TL;DR: An electrostatic model is proposed based on two assumptions: 1) the presence of a positive electrostatic end cap on the halogen atom (except for fluorine) and 2) the electronic charge is anisotropically distributed around the Halogen atom.
Abstract: A study of the halogen···hal- ogen contacts in organic compounds using ab initio calculations and the re- sults of previously reported crystallo- graphic studies show that these interac- tions are controlled by electrostatics. These contacts can be represented by the geometric parameters of the C� X1···X2� C moieties (where q1 = C� X1···X2 and q2 = X1···X2 � C; ri = X1···X2 distance). The distributions of the con- tacts within the sum of van der Waals radii (rvdW) versus qi (q1 = q2) show a maximum at q � 1508 for X = Cl, Br, and I. This maximum is not seen in the distribution of F···F contacts. These re- sults are in good agreement with our ab initio calculations. The theoretical results show that the position of the maximum depends on three factors: 1) The type of halogen atom, 2) the hy- bridization of the ipso carbon atom, and 3) the nature of the other atoms that are bonded to the ipso carbon atom apart from the halogen atom. Calculations show that the strength of these contacts decreases in the follow- ing order: I···I > Br···Br > Cl···Cl. Their relative strengths decrease as a func- tion of the hybridization of the ipso carbon atom in the following order: sp 2 > sp > sp 3 . Attaching an electroneg- ative atom to the carbon atom strengthens the halogen···halogen con- tacts. An electrostatic model is pro- posed based on two assumptions: 1) The presence of a positive electrostatic end cap on the halogen atom (except for fluorine) and 2) the electronic charge is anisotropically distributed around the halogen atom.

TL;DR: It is demonstrated that diabetics had significantly worse oral hygiene, higher severity of gingival disease as measured by the average ofGingival index (GI) and higher severityof periodontal disease as measures by theaverage of probing pocket depth (PPD) and clinical attachment loss (CAL).
Abstract: Background This meta-analysis was conducted to assess the association between diabetes mellitus and periodontal diseases by comparing the extent and severity of periodontal diseases between diabetics and nondiabetics. Methods A literature search was performed using MEDLINE database for published studies from January 1970 through October 2003 with manual search for references in relevant studies. This meta-analysis was based on 18 comparative cross-sectional studies, three prospective cohort studies and baseline data of two clinical trials that compared oral hygiene, gingival and periodontal status between diabetics and nondiabetics. Heterogeneity was obvious among included studies; therefore, the analysis using random-effects model was conducted. Results This study demonstrated that diabetics had significantly worse oral hygiene as measured by the average of plaque index (P1I), higher severity of gingival disease as measured by the average of gingival index (GI) and higher severity of periodontal disease as measured by the average of probing pocket depth (PPD) and clinical attachment loss (CAL). However, diabetics had similar extent of oral hygiene, gingival and periodontal disease as measured by percentages of surfaces or sites with specific scores of P1I, GI, bleeding on probing (BOP), PPD and CAL. Conclusions Diabetics had a significantly higher severity but the same extent of periodontal disease than nondiabetics.

TL;DR: Children's and parents' attitudes toward oral health and dental care need to be improved and comprehensive oral health educational programs for both children and their parents are required to achieve this goal.
Abstract: The aim of this study was to assess the knowledge, attitude, and behavior of school children towards oral health and dental care as well as to evaluate the factors that determine these variables. School children (n=557) of an average age of 13.5 years attending public schools in North Jordan were recruited into this study. The subjects completed a questionnaire that aimed to evaluate young school children's behavior, knowledge, and perception of their oral health and dental treatment. The participants' oral hygiene habits (such as tooth brushing) were found to be irregular, and parents' role in the oral hygiene habits of their children was limited. The study population showed higher awareness of caries than periodontal conditions. Irregular visits to the dentist were found to be common, and toothache was the major driving factor for dental visits. Children had positive attitudes toward their dentists; nevertheless, they indicated that they feared dental treatment. The children in this study also recognized the importance of oral health to the well-being of the rest of the body. Parents were not proactive in making sure that their children received regular dental care. Parents' knowledge and attitudes about the importance of oral health care and their fears about dental treatment influenced their children's dental care. The results of this study indicate that children's and parents' attitudes toward oral health and dental care need to be improved. Comprehensive oral health educational programs for both children and their parents are required to achieve this goal.

TL;DR: Women with repeated IVF-embryo transfer failure should be screened for thrombophilia, which has a significant role in IVF and embryo transfer implantation failure.
Abstract: BACKGROUND: The objective of this study was to determine the incidence of undiagnosed thrombophilic factors and its relation to IVF and embryo transfer failure in women who have had three or more previous IVF-embryo transfer cycles. METHODS: The study group comprised of 90 consecutive women with three or more previously failed IVF-embryo transfer cycles (group A). Two control groups were enrolled: group B (n = 90) included women who have had successful pregnancy after their first IVF-embryo transfer cycle, and group C (n = 100) included women who conceived spontaneously with at least one uneventful pregnancy and no previous history of miscarriage. All women were tested for the presence of inherited [factor V Leiden (FVL) mutation, prothrombin mutation, methylenetetrahydrofolate reductase (MTHFR) mutation and deficiencies in proteins S and C and antithrombin III] or acquired (lupus anticoagulant and anticardiolipin) thrombophilic factors. RESULTS: An increase in the incidences of FVL, MTHFR and antiphospholipid antibodies was found in the study group compared with the two control groups. At least one inherited or acquired thrombophilic factor was detected in 68.9% of women with repeated IVF failure compared with 25.6 and 25% in the groups B and C, respectively (P < 0.01). Combined thrombophilia (two or more thrombophilic factors) was significantly higher in women who have had repeated IVF failure as compared with the two control groups (35.6 versus 4.4 and 3%) (P < 0.0001). CONCLUSION: Thrombophilia has a significant role in IVF-embryo transfer implantation failure. Women with repeated IVF-embryo transfer failure should be screened for thrombophilia.

TL;DR: Direct pulp capping is recommended after mechanical exposure with immediate placement of permanent restoration, while root canal therapy would be the choice of treatment if the exposure was due to caries.
Abstract: Background The decision between pulp capping and root canal therapy after pulp exposure is a clinical issue. The aim of the authors' study was to evaluate the outcome of direct pulp-capping procedures performed by dental students. Methods The authors followed the treatment outcomes of 193 patients with 204 pulp exposures with direct pulp capping. They determined the outcome of pulp capping radiographically using periapical radiographs taken at least three years after pulp exposure. The outcome was considered as successful if the tooth was present and not associated with periapical radiolucency or root canal treatment; otherwise, the outcome was considered as being a failure. Results Overall, the success rate of pulp capping was 59.3 percent. The success was associated more with mechanical exposure than with carious exposure (92.2 versus 33.3 percent) ( P P P = .009). Patients' age, sex, and tooth location and position had no significant effect on the outcome ( P > .05). Conclusion The success rate of direct pulp capping was 92.2 percent with mechanical exposure and 33.3 percent with carious exposure. Clinical Implications Direct pulp capping is recommended after mechanical exposure with immediate placement of permanent restoration, while root canal therapy would be the choice of treatment if the exposure was due to caries.

TL;DR: In this paper, a large number of Cu-based archaeological artefacts from the Mediterranean basin have been selected for investigation of their chemical composition, metallurgical features and corrosion products (i.e. the patina).
Abstract: A large number of Cu-based archaeological artefacts from the Mediterranean basin have been selected for investigation of their chemical composition, metallurgical features and corrosion products (i.e. the patina). The guidelines for the selection of the Cu-based artefacts have taken into account the representativeness of the Mediterranean archaeological context, the manufacturing technique, the degradation state and the expected chemical composition and structure of the objects. The results show wide variation of the chemical composition of the alloys that include all kinds of ancient Cu-based alloys such as low and high tin, and also leaded bronzes, copper and copper-iron alloys. The examination of the alloy matrix shows largely different metallurgical features thus indicating the use of different manufacturing techniques for producing the artefacts. The results of the micro-chemical investigation of the patina show the structures and the chemical composition of the stratified corrosion layers where copper or tin depletion phenomenon are commonly observed with a remarkably surface enrichment of some soil elements such as P, S, Ca, Si, Fe, Al and Cl. This information indicates the strict interaction between soil components and corrosion reactions and products. In particular, the ubiquitous and near constant presence of chlorine in the corrosion layers is observed in the patina of the archaeological Cu-based artefacts found in different contexts in Italy, Turkey, Jordan, Egypt, Spain and Tunisia. This latter occurrence is considered dangerous because it could induce a cyclic corrosion reaction of copper that could disfigure the artefact. The micro-chemical and micro-structural results also show that another source of degradation of the bronze archaeological artefacts, are their intrinsic metallurgical features whose formation is induced during the manufacturing of the objects, carried out in ancient times by repeated cycles of cold or hot mechanical work and thermal treatments. These combined treatments induce crystallisation and segregation phenomena of the impurities along the grain boundaries and could cause mechanical weakness and increase the extent of the inter-granular corrosion phenomena.

TL;DR: An approach that employs fuzzy decision making (FDM) to combine these three measures into one measure namely the project management internal efficiency (PMIE) which should represent an overall estimate of how well the project was managed and executed.
Abstract: Specific applications of fuzzy logic in project management are relatively few in comparison to other application areas. The criteria of project cost, project time, and project quality may be considered as project management internal measures of efficiency. The objective of this research is to present an approach that employs fuzzy decision making (FDM) to combine these three measures into one measure namely the project management internal efficiency (PMIE) which should represent an overall estimate of how well the project was managed and executed. The proposed approach for the evaluation of PMIE is illustrated on a case study. A fuzzy decision making system is designed and implemented using the MATLAB software for the evaluation of the PMIE The methodology and procedure proposed in this research may be easily implemented by project management organizations. The evaluation of PMIE can serve for project managers and for project organizations as an indicator for the level of achievement of the project management internal objectives. PMIE may help in the evaluation of the performance of project teams.

TL;DR: The analytical hierarchy process (AHP) was applied to select a material for a simple product utilising Expert Choice software and confidence in the output is found to be high owing to the low inconsistency of the decision maker's judgement.
Abstract: Material selection is a rapidly growing multi-criteria decision-making (MCDM) problem owing to the large number of factors affecting decision making. The right choice of available material is critical to the success and competitiveness of the manufacturing organisation. The analytical hierarchy process (AHP) is a tool designed to solve MCDM problems. The AHP was applied to select a material for a simple product (a key) utilising Expert Choice software. Confidence in the output is found to be high owing to the low inconsistency of the decision maker's judgement. Sensitivity analysis was performed to increase the confidence in the choice of material.

TL;DR: In this article, a study was conducted to identify Jordanian nursing students' attitudes towards older people and to consider whether the attitudes of the selected sample had any bearing on the care provided for this client group.
TL;DR: A hybrid traceback approach in which packet marking and packet logging are integrated in a novel manner so as to achieve the best of both worlds, to achieve a small number of attack packets to conduct the traceback process and a small amount of resources to be allocated at intermediate routers for packet logging purposes.
Abstract: Tracing DoS attacks that employ source address spoofing is an important and challenging problem. Traditional traceback schemes provide spoofed packets traceback capability either by augmenting the packets with partial path information (i.e., packet marking) or by storing packet digests or signatures at intermediate routers (i.e., packet logging). Such approaches require either a large number of attack packets to be collected by the victim to infer the paths (packet marking) or a significant amount of resources to be reserved at intermediate routers (packet logging). We adopt a hybrid traceback approach in which packet marking and packet logging are integrated in a novel manner, so as to achieve the best of both worlds, that is, to achieve a small number of attack packets to conduct the traceback process and a small amount of resources to be allocated at intermediate routers for packet logging purposes. Based on this notion, two novel traceback schemes are presented. The first scheme, called distributed link-list traceback (DLLT), is based on the idea of preserving the marking information at intermediate routers in such a way that it can be collected using a link list-based approach. The second scheme, called probabilistic pipelined packet marking (PPPM), employs the concept of a "pipeline" for propagating marking information from one marking router to another so that it eventually reaches the destination. We evaluate the effectiveness of the proposed schemes against various performance metrics through a combination of analytical and simulation studies. Our studies show that the proposed schemes offer a drastic reduction in the number of packets required to conduct the traceback process and a reasonable saving in the storage requirement.
TL;DR: In this article, the authors evaluate practice, knowledge and attitude to breastfeeding and assess factors associated with breastfeeding among women in the north of Jordan in the Middle East region of the country.
Abstract: Background
In Jordan, as in neighboring countries in the Middle East, higher education and higher employment rates in recent years among women have had an impact on traditionally based infant feeding. The objective of this study was to evaluate practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in the north of Jordan.
TL;DR: In this article, a new geo-environmental approach was proposed to use waste tires in certain engineering applications and thereby reduce the potential impact on the environment, where shredded tires improved some engineering properties of sand.
Abstract: A new geo-environmental approach was proposed to use waste tires in certain engineering applications and thereby reduce the potential impact on the environment. This paper presents a laboratory study on the effect of shredded tires on the physical properties of some sands. Shredded tires were passed through US sieve size 4 and mixed with three different types of sands with varying gradations. Each type of sand was mixed with four different percentages of shredded tires: 10, 20, 30 and 40% by dry weight. Direct shear tests were conducted to study the effect of the shredded tires on the shear strength properties of sands, such as angle of internal friction and shear strength. The addition of shredded waste tires increased both the angle of internal friction and the shear strength of the sands. Additionally, a prediction model was developed to calculate the shear strength of sand due to increasing shredded tire content. The shredded tires improved some engineering properties of sand.
TL;DR: The prevalence of two canals in this group of mandibular incisors was 26.2% and is within the range of previous studies performed on populations of different racial origin.
Abstract: Al-Qudah AA, Awawdeh LA. Root canal morphology of mandibular incisors in a Jordanian population. International Endodontic Journal, 39, 873–877, 2006. Aim To investigate the root canal morphology of mandibular incisors in a Jordanian population using a canal staining and tooth-clearing technique. Methodology Four hundred and fifty extracted mandibular incisors were collected from dental clinics within north Jordan. Following pulp tissue removal and staining of the canal systems, the teeth were decalcified with 5% nitric acid, dehydrated with ascending concentrations of alcohol and rendered clear by immersion in methyl salicylate. Cleared teeth were examined by eye and the following features were evaluated: (i) number and type of root canals; (ii) presence and location of lateral canals and intercanal communications; (iii) location of apical foramina; and (iv) frequency of apical deltas. Results The majority of mandibular incisors had a single canal (73.8% of teeth possessed a Type I canal system). Although 26.2% of the roots possessed two canals, only 8.7% had two separate apical foramina. Conclusions The prevalence of two canals in this group of mandibular incisors was 26.2% and is within the range of previous studies performed on populations of different racial origin.
TL;DR: The main conclusion of this survey is that the use of medicinal herbs among diabetic patient in Jordan is common and it is essential to increase the level of awareness among diabetic patients and health care providers regarding the efficacy and toxicity of these medicinal herbs.
Abstract: Diabetes mellitus is the most common metabolic disorder worldwide. To date, there have been no reports on the frequency of use of herb medicines in the managements of diabetes mellitus in Jordan. This cross-sectional study was conducted by interviewing 310 diabetic patients visiting two medical centers in Jordan: Jordan University of Science & Technology Medical Center and Sarih Medical Center between December 2003 and August 2004. It is found that 31% of interviewed patients have used herbal products (96 patients). The results revealed that the most commonly used herbs by diabetic patients in Jordan were Trigonella foenumgraecum (22.9%), Lupinus albus (14.6%), Allium sativum (11.5%), Allium cepa (5.2%), Nigella sativa (7.3%), Zea mays L. (6.3%), Urtica dioica L. (8.3%), Eucalyptus globules LA (9.4%), Olea europea L. (3.1%), Cumminum cyminum (9.4%), Coriandrum sativum (10.4%), Salvia officinalis L. (3.1%), and Tilia cordata (1%). Furthermore, it is found that 47.9% of the patients used herbs according to advice from their friends on a daily basis. The side effects were reported by 36.5% of the patients and include headache, nausea, dizziness, itching, palpitation, and sweating. Among the patients, 72.9% used the herbs as adjunctive therapy along with their anti-diabetic drugs and 80.2% of the patients informed their physicians about their use. A 79.2% of the sample confirmed their intention to re-use these herbs as 86.5% of them were satisfied with their diabetes control. There was a significant relationship between the use of herbs, the patient's place of residence and his/her level of education. The main conclusion of this survey is that the use of medicinal herbs among diabetic patient in Jordan is common. Therefore, it is essential to increase the level of awareness among diabetic patients and health care providers regarding the efficacy and toxicity of these medicinal herbs.
TL;DR: The results suggest that long term exposure to ELF could have adverse effects on mammalian fertility and reproduction.
Abstract: The effects of an extremely low frequency (ELF) magnetic field on the sex hormones and other fertility parameters of adult male Sprague-Dawley rats were investigated. Adult male rats were exposed to a 50 Hz sinusoidal magnetic field at approximately 25 microT (rms) for 18 consecutive weeks. There were no significant effects on the absolute body weight and the weight of the testes of the exposed rats. However, the weights of seminal vesicles and preputial glands were significantly reduced in the exposed male rats. Similarly, a significant reduction in sperm count was observed in the exposed group. Furthermore, there were no significant effects on the serum levels of male follicle stimulating hormone (FSH) during the 18 weeks of exposure period. On the other hand, there was a significant increase in the serum levels of male luteinizing hormone (LH) after 18 weeks of exposure (P < .005), while testosterone levels were significantly decreased only after 6 and 12 weeks of the exposure period. These results suggest that long term exposure to ELF could have adverse effects on mammalian fertility and reproduction.
TL;DR: Young age of onset, shorter duration of illness, a relapsing remitting pattern, and use of interferon were identified as statistically significant predictors of less disability.
Abstract: To characterize the clinical, demographic and epidemiological features of multiple sclerosis (MS) in Jordan. Data for consecutive Jordanian patients, fulfilling the McDonald criteria for clinically definite and clinically probable MS, during the time period 2004–2005 were collected and analyzed in the three major referral centers for MS in Jordan. We identified a total of 224 patients (165 females, 87%; 59 males, 13%). The mean (±SD) age of onset was 29.3 (±9.6) years, and mean (±SD) duration of illness was 3.9 (±9.3) years. The prevalence of MS in the city of Amman was 39/100,000. The prevalence of MS in Irbid, north Jordan, was 38/100,000. The most frequent presentation was weakness (30.8%), followed by optic neuritis (20.1%), sensory impairment (19.6%), and ataxia (14.3%). A relapsing remitting pattern was identified in 90.2% of patients, the rest being primary and secondary progressive, and one patient had a progressive relapsing course. Family history of MS was found in 9.4% of the cases. About 60% of the patients were using interferon beta. The degree of physical disability was determined using the Expanded Disability Status Scale (EDSS). Younger age of onset, shorter duration of illness, a relapsing remitting pattern, and use of interferon were identified as statistically significant predictors of less disability. Jordan is a medium-high risk country for MS, with prevalence higher than what has previously been reported, possibly representing an increase in incidence. Clinical and demographic characteristics are similar to most reports worldwide.
TL;DR: The effects of application method and concentration of gibberellic acid, paclobutrazol and chlormequat on black iris performance were assessed and it was indicated that the tallest plants in the GA3 experiment were those sprayed with 250 mg L−1.
TL;DR: Consumer results showed that no significant differences of fortification of soy protein isolate, chickpea, or broad bean flour as well as ISP and the control of sensory quality attributes of liking and JAR were found except for overall flavor and color.
Abstract: This study evaluated the effectiveness of substituting different concentrations of chickpea flour, broad bean flour, or isolated soy protein (ISP) on the physicochemical and sensory properties of biscuits. Fortification processes were conducted by substituting specified concentrations (3%, 6%, 9%, and 12%) of both broad bean and chickpea and (3%, 6%, and 9%) ISP from the total percent of wheat flour (100%). Proximate chemical analysis results of biscuits showed that fortification increased protein contents from 16.57% to 22.84%. Results indicated that fortification decreased spread factor compared with the control. Sensory and instrumental color results showed that fortified chickpea increased the lightness, while fortification with broad bean or ISP increased the darkness. Descriptive results showed that as the fortified ISP and chickpea ratios increased most of liking and just about right (JAR) attributes decreased, while they increased for fortified broad bean. Descriptive analysis also showed that 3% of fortified ISP and chickpea or 12% of broad bean provided the best quality ratios within each type of fortification. Consumer results showed that no significant differences of fortification of soy protein isolate (3%), chickpea (3%), or broad bean (12%) and the control of sensory quality attributes of liking and JAR were found except for overall flavor and color. Fortification of chickpea and broad bean flour as well as ISP could be used in production of high-protein biscuits.
TL;DR: Examination of the effects of extracts of two chewing sticks on proliferation of fibroblasts and viability of cariogenic bacteria shows that aqueous extracts of miswak and derum enhance the growth of fibrobasts and inhibit the Growth of caruogenic bacteria.
Abstract: : Objectives: This study examined the effects of extracts of two chewing sticks on proliferation of fibroblasts and viability of cariogenic bacteria. Methods: Aqueous extracts of miswak (Salvadora persica; Arak tree) and derum (Juglans regia; walnut tree) were prepared and their effects investigated on growth of Balb/C 3T3 mouse fibroblasts by measuring the mitochondrial succinic dehydrogenase activity. Furthermore, the effects on the viability of various cariogenic bacteria (Streptococcus mutans, Streptococcus salivarius, Lactobacillus casei and Actinomyces viscosus) was also determined. Results: The data revealed that Balb/C 3T3 fibroblasts exposed to aqueous extracts of miswak or derum showed an increase in cell proliferation by 156% and 255%, respectively, in comparison with controls (p<0.0001). Furthermore, extracts from both miswak and derum had adverse effects on the growth of the cariogenic microorganisms, with derum having significantly greater antimicrobial effects than miswak and at much lower concentrations against all the bacteria tested. The most sensitive organisms were A. viscosus, followed by S. mutans, S. salivarius, with L. casei being the most resistant. Conclusion: The results show that aqueous extracts of miswak and derum enhance the growth of fibroblasts and inhibit the growth of cariogenic bacteria, with the derum extract showing greater activity than miswak.
TL;DR: Neuroticism was found the main predictor of the patients' oral health-related quality of life following implant treatment, and personality traits provide valuable information for the prediction of patients' satisfaction with their implant-supported prostheses.
Abstract: Objectives: The literature has shown that patients' satisfaction with dental prostheses is associated with the existence of certain personality profiles. It is important to study such relationships in dental implant patients.
Material and methods: Fifty patients (28 men and 22 women), aged between 22 and 71 years (mean age 43.22 years, SD 12.24 years), who were partially edentulous and were seeking dental implant therapy were entered into this study. The patients were requested to answer two reliable and valid questionnaires – the Dental Impact on Daily Living (DIDL) and the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) – before implant treatment and 2–3 months after prosthodontic rehabilitation therapy.
Results: Certain personality traits were found to have a significant relationship with patients' satisfaction with dental implants both before and after implant therapy (P<0.05). Neuroticism score had valuable features in predicting patients' total satisfaction ratings (P=0), satisfaction with appearance dimension (P=0), satisfaction with oral comfort dimension (P=0.005) as well as satisfaction with general performance dimension (P=0).
Conclusion: Personality traits have an impact on patients' satisfaction with dental implant therapy. In addition, personality traits provide valuable information for the prediction of patients' satisfaction with their implant-supported prostheses. Neuroticism, openness, agreeableness and consciousness are very helpful in this regard. Neuroticism was found the main predictor of the patients' oral health-related quality of life following implant treatment.
TL;DR: The incidence and recurrence rate of luteinized unruptured follicle (LUF) syndrome are significantly increased in subsequent cycles of IUI in women with unexplained infertility undergoing intrauterine insemination.
Abstract: Background The objective of this study was to determine the incidence and recurrence rate of luteinized unruptured follicle (LUF) syndrome in women with unexplained infertility undergoing intrauterine insemination (IUI). Methods A total of 167 women with unexplained infertility who underwent 292 cycles of IUI were enrolled in the study. All patients were treated with clomiphene citrate, 50-150 mg/daily from day 5 to 9 of their menstrual cycle. Ultrasound examination to confirm ovulation was performed on the day of IUI (day 0) and every day thereafter for another 3 days (days 1, 2 and 3). A total of 69 women who failed to conceive in the first cycle and 56 women who failed to conceive in the second cycle underwent second and third cycles, respectively. Results Of the total 167 patients who underwent first cycle, 42 (25%) had LUF. The incidence of LUF was 56.5% in 69 patients who underwent a second cycle of IUI treatment, of whom 33 patients had LUF in the first cycle with recurrence rate of 78.6%. In 56 patients who underwent 3 consecutive cycles, the incidence of LUF was 58.9% and recurrence rate of 90%. No pregnancies were recorded in patients with LUF during the study period. Conclusion The incidence and recurrence rate of LUF are significantly increased in subsequent cycles of IUI. In these patients, other options of infertility treatment might be justified.
TL;DR: Accumulation of dehydrin-like proteins was maximal in seeds harvested at 43 d after R 5 (seed physiological maturity) and under irrigation and nonirrigation conditions, with the first detection for dehydrins at 22 d afterR 5 (R 6 ).
Abstract: There is no information on accumulation of dehydrin proteins during seed development and maturation of soybean [Glycine max (L.) Merr.j in response to drought stress. Our objective was to study accumulation of dehydrin-like proteins in developing soybean seeds in response to drought stress. A greenhouse experiment and a field experiment were conducted. In the greenhouse experiment, three treatments were imposed on soybean plants after beginning of linear seed filling (R 5 ): well-watered (WW), gradual stress (GS) imposed before severe stress, and sudden severe stress (SS). In the field treatments were irrigation (I) and nonirrigation (NI) (rainfed) conditions imposed from R 5 to R 8 (mature seeds). Greenhouse results indicated dehydrin-like proteins (28 and 32 kDa) were detected 18 d after R 5 (R 5.8 ) in developing seeds from drought-stressed plants but not in seeds from the well-watered plants. In the mature seeds, dehydrin-like proteins (28, 32, and 34 kDa) were detected in seeds from drought-stressed plants as well as the well-watered plants. In the field, dehydrin-like proteins accumulated similarly under irrigation and nonirrigation conditions, with the first detection for dehydrins (28 and 32 kDa) at 22 d after R 5 (R 6 ). Accumulation of dehydrin-like proteins was maximal in seeds harvested at 43 d after R 5 (seed physiological maturity).
TL;DR: The preliminary results from the ARMed project appear to support previous sporadic reports suggesting high antibiotic resistance in the Mediterranean region and suggest that this is particularly the case in the eastern Mediterranean region where resistance in S. aureus and E. coli seems to be higher than that reported in the other countries of the Mediterranean.
Abstract: Sporadic reports from centres in the south and east of the Mediterranean have suggested that the prevalence of antibiotic resistance in this region appears to be considerable, yet pan-regional studies using comparable methodology have been lacking in the past. Susceptibility test results from invasive isolates of Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Enterococcus faecium and faecalis routinely recovered from clinical samples of blood and cerebrospinal fluid within participating laboratories situated in Algeria, Cyprus, Egypt, Jordan, Lebanon, Malta, Morocco, Tunisia and Turkey were collected as part of the ARMed project. Preliminary data from the first two years of the project showed the prevalence of penicillin non-susceptibility in S. pneumoniae to range from 0% (Malta) to 36% (Algeria) [median: 29%] whilst methicillin resistance in Staphylococcus aureus varied from 10% in Lebanon to 65% in Jordan [median: 43%]. Significant country specific resistance in E. coli was also seen, with 72% of isolates from Egyptian hospitals reported to be resistant to third generation cephalosporins and 40% non-susceptible to fluoroquinolones in Turkey. Vancomycin non-susceptibility was only reported in 0.9% of E. faecalis isolates from Turkey and in 3.8% of E. faecium isolates from Cyprus. The preliminary results from the ARMed project appear to support previous sporadic reports suggesting high antibiotic resistance in the Mediterranean region. They suggest that this is particularly the case in the eastern Mediterranean region where resistance in S. aureus and E. coli seems to be higher than that reported in the other countries of the Mediterranean.

TL;DR: Tooth wear had an adverse effect on several aspects of patient satisfaction in patients with atypical gum disease.
Abstract: PURPOSE The aim of this study was to identify the effects of tooth wear on patients' quality of life and satisfaction with their dentition. MATERIALS AND METHODS Seventy-six tooth wear patients and 76 control subjects were recruited for the study. A Dental Impact on Daily Living questionnaire was used to assess the affect of tooth wear on daily living and satisfaction with the dentition. An ordinal scale was used to assess the severity of tooth wear in a patient cohort. RESULTS The results showed that tooth wear has a measurable impact on patients' satisfaction with their appearance, pain levels, oral comfort, general performance, and chewing and eating capacity (P < .001). CONCLUSION Tooth wear has an impact on patients' satisfaction with their dentition regardless of tooth wear severity or personal factors.
