TL;DR: In this paper, the physicochemical and functional properties of brown rice and wheat flour were studied and biscuits were prepared with the incorporation of Brown rice flour in 0, 5, 10, 15 and 20 % with the wheat flour to assess the quality and acceptability of the biscuits.
Abstract: The consumer demand is increasing for composite flour based bakery products like biscuits. The incorporation of brown rice flour can be justified in composite flour based biscuits as it has beneficial nutraceutical properties and its gluten-free nature can play important role in preventing celiac problem. The physicochemical and functional properties of brown rice and wheat flour were studied and biscuits were prepared with the incorporation of brown rice flour in 0, 5, 10, 15 and 20 % with the wheat flour to assess the quality and acceptability of the biscuits. The water absorption capacity of brown rice flour was lower than that of wheat flour (p≤0.05), whereas oil absorption and foaming capacity of brown rice flour were significantly higher than that of wheat flour (p ≤0.05). The brown rice flour had higher least gelation concentration (30.66%) as compared with wheat flour (20.33%). As the concentration of brown rice flour was increased, spread ratio of biscuits decreased. The biscuits containing 5, 10 and 15% brown rice flour indicated that addition of increasing level of brown rice flour had higher ash, fat, moisture and crude fiber contents, while protein and total carbohydrate contents found lower in the biscuits. Statistical analysis of biscuits containing various amount of brown rice flour (0, 5, 10, 15 and 20% brown rice flour) showed that control biscuits (0% brown rice flour) secured the highest score for color, flavor, texture and overall acceptability, which is followed by biscuits containing 10, 5,15 and 20% brown rice flour.

TL;DR: Ethanolic extracts of some fruits of Cucurbitaceae family such as Cucumis sativus (cucumber), Lagenaria siceraria (white pumpkin), Luffa acutangula (ridge gourd), Citrullus lanatus (sweet melon) and Cucarbita maxima (pumpkin) have been studied for their hypoglycemic effects on alloxan induced diabetic rats (AIDRs).
Abstract: Ethanolic extracts of some fruits of Cucurbitaceae family such as Cucumis sativus (cucumber), Lagenaria siceraria (white pumpkin), Luffa acutangula (ridge gourd), Benincasa hispida (ash gourd), Citrullus lanatus (sweet melon) and Cucarbita maxima (pumpkin) have been studied for their hypoglycemic effects on alloxan induced diabetic rats (AIDRs). Screening results suggested that among the tested fruits the hypoglycemic potency follows: cucumber > white pumpkin > ridge gourd. These three fruit-extracts were further investigated for their hypoglycemic, hypolipidemic and glycogenesis effects. Cucumber, white pumpkin and ridge gourd extracts reduced blood glucose level by 67, 65 and 51%, respectively at 12 hours after single intraperitone al injection; while reduced the low density lipoprotein (LDL) level to 13, 28 and 86%, respecti vely in AIDRs. The maximum reduction 87% was observed by cucumber extract. Cucumber, white pumpkin and ridge gourd extracts reduced total cholesterol level to 29, 15 and 38%, respectively comparing with the diabetic control group. Here the maximum reduction of 85% was observed by white pumpkin extract. Cucumber, white pumpkin and ridge gourd also reduced triglyceride levels to 72, 68 and 80%, respectively. Maximum reduction of 32% was observed by white pumpkin. Significant improvement of glycogenesis was also observed by ridge gourd extracts in AIDRs.

TL;DR: Wang et al. as mentioned in this paper proposed a tertiary-amine-type gel, named WPD, which exhibited selectivity only for Mo(VI) and Re(VII) with a remarkably high capacity 4.99 mol·kg−1 and 0.96 mol· kg−1, respectively.
Abstract: Waste paper was chemically modified with dimethylamine (DMA) to obtain a tertiary-amine-type gel, named WPD. By comparing with the adsorption of other coexisting metals, such as Pb(II), Ca(II), Zn(II), Mn(VII), and Ni(II), this novel gel exhibited selectivity only for Mo(VI) and Re(VII) with a remarkably high capacity 4.99 mol·kg–1 and 0.96 mol·kg–1, respectively. The adsorption mechanism of Mo(VI) and Re(VII) on the WPD gel was proposed as the anion exchange process. In addition, both the adsorption behavior obeys the Langmuir model, and the endothermic adsorption process followed pseudosecond-order kinetics. Also, the effectiveness of recovery and separation of Mo(VI) and Re(VII) from industrial wastewater was also tested using a column packed with the WPD gel, and it showed highly encouraging results with respect to the stability of the gel and selectivity for the targeted metal ions in the presence of excess of other metal ions.

TL;DR: Evidence showed that geinstein increases osteoblasts formation as well as decreases osteoclast production, which proves the potentiality of phytoestrogens as a source of bioactive substance.
Abstract: Genistein recognized as phytoestrogens is one of the most extensively studied isoflavones. It comprises of significant portion of Asian diet including Japanese and Chinese cuisine in the form of Soy food products. Evidence showed that geinstein increases osteoblasts formation as well as decreases osteoclast production. It plays an important role in immunity; such as suppression of delayed hypersensitivity and increases host resistance to B16F10 tumor by proliferating cytotoxic T and NK cells. It also decreases the activity of lipoprotein lipase which in turn inhibits lipogenesis and prevents the uptake of glucose in type 2 diabetic in rats. Geinstein play important role in reproductive system where it regulates the productive of oestrogen and progesterone. Moreover Geinstein has the ability to inhibit the tumor and cancer cell proliferation. Numerous beneficial effect of Geinstein including cancer treatment and function in immunity, obesity, diabetes and reproductivity Geinstein proves the potentiality of phytoestrogens as a source of bioactive substance.

TL;DR: Investigation of the effects of combination drugs (metformin and atorvastatin) on long-term alloxan-induced diabetes with CVD in rats may suggest that treatment with combination therapy is more effective than mono-therapy for preventing diabetes with DPPH free radical scavenging activity.
Abstract: The present study was designed to investigate the effects of combination drugs (metformin and atorvastatin) on long-term alloxan-induced diabetes with CVD in rats. In short-term alloxan-induced diabetic rats, metformin reduced significant amount of glucose in blood, but it had no significant effect on lipid profile. Atorvastatin significantly reduced TC, TG and LDL-C, whereas it increased significant amount of HDL-C. However, pathological changes of heart were not observed after short-term induction of alloxan in rats. In long-term induction of diabetes by alloxan, LV hypertrophy was observed and cardimyocyte size in rats was increased. Atorvastatin alone and in combination with metformin significantly reduced the LV hypertrophy, cardiomyocyte size, TC, TG and LDL-C level. They increased significant amount of HDL-C level and showed significant DPPH free radical scavenging activity. Present findings may suggest that treatment with combination therapy is more effective than mono-therapy for preventing diabetes with CVD in rats. © 2012 JSR Publications.

TL;DR: The vaccine potential of Streptococcus iniae ghosts produced by gene E mediated lysis was investigated using tilapia and fish immunized with SIG and formalin killed S. iniae (FKC) vaccines showed significantly higher serum agglutination titres than control fish.
Abstract: The vaccine potential of Streptococcus iniae ghosts produced by gene E mediated lysis was investigated using tilapia ( Oreochromis niloticus ). Tilapia immunized with S. iniae ghosts (SIG) and formalin killed S. iniae (FKC) vaccines showed significantly higher serum agglutination titres than control fish. Fish immunized with SIG showed no significant differences with fish immunized with FKC in serum agglutination titres, but showed significantly higher bactericidal activity than fish immunized with FKC. Furthermore, fish immunized with SIG showed higher protection than fish immunized with FKC. As this promising type of a non-living whole cell envelope preparation seems to be favorable over conventional vaccines, we suggest S. iniae ghosts as a new vaccine candidate DOI: http://dx.doi.org/10.3329/bvet.v29i1.11889 Bangl. vet . 2012.

TL;DR: In this article, the authors proposed a new scheme to detect microwave using surface plasmon resonance (SPR) generated in optical fiber (OF), which is the result of the related Bragg wavelength shift in the optical fiber due to temperature change.
Abstract: Microwaves (MW) sensing is done through complex and big size detector or sensor which comprises a lot of elements. In this paper a new scheme to detect MW is proposed. The motivation is to minimize the conventional MW detector size and reduce the number of elements in the detector by using a new technology. Here MW is detected by measuring the surface plasmon wavelength shift which is the result of the related Bragg wavelength shift (0.009 nm/ °C) in the optical fiber due to temperature change. The analysis is done through experimental procedure and related result comparison of different research papers to get the possibility to detect the MW using Surface Plasmon Resonance (SPR) generated in Optical Fiber (OF).

TL;DR: The results suggest that methanol extract of the aerial parts of Aerva lanata could be a source of natural anticancer and antioxidant compounds.
Abstract: The present study was conducted to demonstrate the antioxidant and anticancer effects of methanol extract of the aerial parts of Aerva lanata Linn. In vitro antioxidant potentiality was tested using DPPH radical scavenging test, total phenol and flavonoid content and reducing power determination assays. The extracts showed moderate antioxidant activity in a dose dependent manner. In vivo anticancer activity was studied against Ehrlich Ascites Carcinoma (EAC) cells in Swiss albino mice by monitoring parameters like tumor weight measurement, survival time and tumor cell growth inhibition. It has been found that the compound at the dose of 40 mg/kg/day (i.p) significantly decreases tumor weight, increases life span and reduces tumor cell growth rate in comparison to those of EAC bearing mice receiving no extract. These results suggest that methanol extract of the aerial parts of Aerva lanata could be a source of natural anticancer and antioxidant compounds. In vitro cytotoxicity of the same extract was also assessed to link the finding with the potent anticancer activity of the experimental extract (LC50 less than 50 μg/ml).
TL;DR: The aim of the present study was to assess whether the proportion of adults with acute HAV infection has been increasing over the years and analyze the seroprevalence of immunoglobulin M(IgM) anti- HAV antibodies in young adults below the age of 20 years as well as in cases of chronic liver disease.
Abstract: Hepatitis A (HAV) infection is caused by the hepatitis A virus which is transmitted through the fecal-oral route. Life long protective antibodies are present after infection. The number of cases of adult hepatitis A has progressively been increasing during the last several decades in Bangladesh. In addition, the pattern of age-specific seroprevalence of anti-HAV has changed with economic growth. The prevalence of anti-HAV in 20-40 year age range has declined rapidly during the last 3 decades. As a result, this age groups has a high risk for HAV infection and clinically overt hepatitis A is increasing in adolescents and adult. The aim of the present study were to assess whether the proportion of adults with acute HAV infection has been increasing over the years and analyze the seroprevalence of immunoglobulin M(IgM) anti- HAV antibodies in young adults below the age of 20 years as well as in cases of chronic liver disease. Sera collected from 530 patients with acute and chronic liver disease attends the Somorita Hospital Ltd. during the previous 2 years and 6 months (Jan. 2008- Jun. 2010) were tested for various serological markers of acute and chronic hepatitis. In addition, 530 normal healthy attendants of the patients above the age of 20 years were tested for IgM anti-HAV as controls. Of 530 patients with acute hepatitis (13.42%) were positive for immunoglobulin M. The patients who were IgM anti-HAV negative were found to be hepatitis B (106 patients), hepatitis C, (10 patients), hepatitis E (150 patients) and unclassified (273 patients). Although the frequency of HAV infection among young adult (< 20 age) had increased (33.33% to 42.35%) in the 2 years and 6 months period, the frequency of HAV infection among adults had also increased (15.38% to 28.13%) during the same period. This study should be helpful for the identification of high risk population for vaccination of hepatitis A. DOI: http://dx.doi.org/10.3329/bjsir.v47i3.13065 Bangladesh J. Sci. Ind.

TL;DR: There was no significant changed observed in some biochemical parameters in the different age group of Vitiligo patients but some biochemical parameter like total protein, total cholesterol, triglycerides (TG), uric acid and random blood sugar level were significantly changed in different age groups, specially among the 11-20 and 31-40 years age group.
Abstract: This study is focus on the biochemical analysis to investigate the condition of different biochemical parameters for the Vitiligo patients. This biochemical analysis deals with the blood serum level of random blood sugar, bilirubin, urea, total protein, SGOT, SGPT, alkaline phosphatase, total cholesterol and uric acids. The increasing some of the biochemical parameters were statistically significant with the age groups. Random blood sugar analysis of the 125 patient's age group 31- 40, 41- 50 and above 50 significantly higher than the control group. No significant changes were observed in serum bilirubin, serum urea, serum creatinine, serum alkaline phosphatase (ALP) and serum asparate amino transferase (AST) level in different age group of Vitiligo patients. In this study, the serum total proteins were slightly decreased in the age group patients below 10 and 11-20 as compared to healthy controls. The average serum total protein level of the below 10 and 11-20 age group patients were 5.31 g/dl and 6.50 g/dl respectively, whereas the controls were 5.95 g/dl and 6.92 g/dl respectively. Serum cholesterol, serum triglycerides and serum uric acid levels were significantly changed in the age group 11-20 and 31-40 compared with the healthy control. The average serum cholesterol level, triglyceride (TG) level and uric acid level were 152.17 mg/dl, 90.27 mg/dl, 4.75 mg/dl and 173.40 mg/dl, 149.95 mg/dl, 5.54 mg/dl respectively for the patients of 11-20 and 31-40 years age group. The controls of these parameters for the 11-20 years and 31-40 years age groups were 150.57 mg/dl, 94.41 mg/dl, 4.28 mg/dl and 156.75 mg/dl, 101mg/dl, 4.77mg/dl respectively. These biochemical studies on Vitiligo indicated that there was no significant changed observed in some biochemical parameters in the different age group of Vitiligo patients but some biochemical parameters like total protein, total cholesterol, triglycerides (TG), uric acid and random blood sugar level were significantly changed in different age group of Vitiligo patients specially among the 11-20 and 31-40 years age group. This biochemical studies would be helpful to know details about the pathological condition of the Vitiligo patients associated with other disease.
