TL;DR: A combination of GnRH, progestagen sponges and PGF(2alpha) can be effective in synchronizing estrus and improving fecundity in sheep and goats.
Abstract: The objective of this experiment was to evaluate the effect of GnRH, progestagen and prostaglandin F(2alpha) on estrus synchronization in sheep and goats. Sixty Awassi ewes and 53 Damascus does were used in the study. The experiment started at the beginning of the breeding season (June/July). The same treatments were applied to sheep and goats as follows: no treatment (CON), 14-day progestagen sponges and 600 IU equine chorionic gonadotropin (S), gonadotropin releasing hormone followed 5 days later by prostaglandin F(2alpha) (GP) and gonadotropin releasing hormone, progestagen sponges for 5 days and prostaglandin F(2alpha) on the day of sponge removal (GSP). None of the ewes in the S group lambed from mating during the induced cycle. A greater lambing rate (p < 0.05) was observed in the GSP group compared with the CON and S groups while the GP group was intermediate. The number of lambs born per lambed ewe was similar among the CON, GP and GSP groups. However, the number of lambs per exposed ewe was greater (p < 0.05) in the GSP than the remaining groups. The induced cycle kidding rate was 77% for all treatments combined. Similar kidding rate were observed among treatments. The numbers of kids born per kidded and exposed doe from mating during the induced estrus were also similar among treatments. Greater numbers of multiple births were observed in the GP and GSP than in the S group. In conclusion, a combination of GnRH, progestagen sponges and PGF(2alpha) can be effective in synchronizing estrus and improving fecundity in sheep and goats. Although the use of GnRH-PGF(2alpha) was effective, the addition of progestagen sponges at the time of GnRH administration appeared to improve reproductive parameters.

TL;DR: The results suggest that date extract may have multiple effects on Candida with an increasing potential of using it for prophylaxis purposes.
Abstract: The effect of Berhi date extract on the ultrastructure of Candida albicans was studied by scanning and transmission electron microscopy. Exposure of yeast to 5% (w/v) date extract showed evidence of weakening in the cell wall with indications of cell distortion and partial collapse in some cases as seen by scanning electron microscopy. Increasing the concentration of date extract (20%, w/v) led to more drastic damage to the yeast with cell lysis and concurrent leakage of cytoplasmic material with eventual cell death. Ultrastructural investigation showed irregular shapes of cells treated with date extract, with prominent effects on cell wall layers. Cell membranes lost their integrity, aggregation of the cytoplasmic contents and large detachment of plasmalemma from cell wall was observed in the treated cells. These results suggest that date extract may have multiple effects on Candida with an increasing potential of using it for prophylaxis purposes.

TL;DR: It was showed that fertility, as measured by the number of pregnancies, taking into consideration marriage duration, was not affected by consanguinity, and consanguineous marriages showed significantly higher rates of still births and infant mortality in general.
Abstract: OBJECTIVES Consanguinity is a wide spread practice in Jordan. The objective of this study is to explore the health effects of consanguinity, in particular fertility, reproductive wastage, infant mortality and congenital malformations. METHODS A stratified 2 stage cluster sample of 1867 married couples, representative of all population groups and all geographic locations of Jordan were randomly selected. A questionnaire was specially designed to explore each of the objectives set for the study and was field tested. A group of field workers were thoroughly trained on the implementation of this instrument. All 1867 couples were interviewed by these field workers and completed questionnaires were reviewed before data entry. Data analysis was carried out using SPSSX statistical package. Significance tests were performed wherever appropriate. RESULTS The study showed that fertility, as measured by the number of pregnancies, taking into consideration marriage duration, was not affected by consanguinity. Twin pregnancies and abortions did not show any significant difference between consanguineous and non-consanguineous marriages. Consanguineous marriages showed significantly higher rates of still births and infant mortality in general. Within the consanguineous group, female infant mortality rates were significantly higher than those of males. Congenital malformations as reported by mothers of consanguineous marriages were significantly higher than those reported by mothers of non-consanguineous marriages. CONCLUSIONS This study showed that consanguinity has a detrimental effect on many aspects of reproductive health.

TL;DR: There was a negative correlation between quality of life and depression among Jordanian patients with end stage renal disease on maintenance haemodialysis, and depression was higher among women than men, whereas both gender had lowquality of life scores.
Abstract: The purpose of this study was to explore the relationship between quality of life, depression, perception of seriousness of illness and adherence to treatment among Jordanian patients with end stage renal disease on maintenance haemodialysis. The study was carried out using a descriptive, correlation design. A convenience sample of 244 participants was recruited from four major dialysis units in Amman. A self-report questionnaire included demographic data, adherence to treatment and perception of seriousness of illness. Quality of Life Index and Beck Depression Inventory were used for data collection. There was a negative correlation between quality of life and depression (r = −0.05, P = 0.000). Depression was higher among women than men, whereas both gender had low quality of life scores. Higher quality of life has been associated with perceived seriousness of illness and more adherence to treatment regimen. This study provides preliminary evidence to develop culturally sensitive nursing strategies to asses and manage depression, enhance quality of life and adherence to treatment of patients on haemodialysis.
