Background Evaluation of anti-mullerian hormone (AMH) cut-off levels in assisted reproductive technology (ART) as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (OHSS). MaterialsAndMethods In a retrospective study, 177 infertile patients were assessed for AMH in serum and follicular fluid (FF) on the day of follicular puncture (FP...
Background and Objective: Neonatal sepsis is associated with high mortality and has a favourable outcome when recognized and treated in a timely manner. In resource-limited settings, there is a need for an affordable test with a short turnaround time for timely diagnosis of sepsis. The aim of this study was to find out the role of eosinopenia and neutrophil-to-lymphocyte ratio (NLR) in screenin...
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
dxl of calcaneus is a portable method for bmd. this study determined a cut off point for dxl in osteoporosis diagnosis. in 510 healthy postmenopausal women, bmd of axial regions with dxa (dpx-md, ge,lunar corp, madison, wi) and heel with dxl (demeteck- sweden), measured. the agreement of two methods and cut off point for dxl in defining osteoporosis, obtained. dxa found osteoporosis in 34.3% an...
دراین پژوهش که با هدف کلی تعیین حساسیت sensitivity و ویژگی specificity که دو شاخص مهم اعتبار آزمون می باشند و پایایی reliability و آزمون سرند mmse در سرند سالمندان مبتلا به دمانس صورت گرفت.دراین پژوهش جهت برآورد حساسیت و ویژگی آزمون mmse از روش تعیین نقاط برش cut off point استفاده شد و پایایی آن با استفاده از ضریب همبستگی پیرسون محاسبه گردید. نتایج پایایی باز آزمون 73/...
Sarroud Dam is located in the north of Khorasan Razavi Province in the city of Kalat. Being located in a fault zone, it is necessary to inject the cut-off wall. Using remote sensing techniques, geographic information system, Landsat satellite imagery and field observations in this research, it was specified that the dam has been located within the range of the Sarroud Fault. According to this, ...
BACKGROUND AND OBJECTIVE The newly developed Minimal Eating Observation and Nutrition Form - Version II (MEONF-II) has shown promising sensitivity and specificity in relation to the Mini Nutritional Assessment (MNA). However, the suggested MEONF-II cut-off scores for deciding low/moderate and high risk for undernutrition (UN) (>2 and >4, respectively) have not been decided based on statistical ...
BACKGROUND Using the person-oriented approach, we determined the relationships between four indicators (restraint and eating, shape, and weight concerns) of disordered eating (DE), as measured by the self-reported Eating Disorders Examination Questionnaire (EDE-Q), to identify typical DE patterns. We then related these patterns to clinical EDE-Q cut-off scores and emotion dysregulation, depress...
We have demonstrated recently that incubation of the aminoglycoside gentamicin with an hepatic post-mitochondrial fraction produces a compound toxic to sensory cells from the inner ear in short-term culture; in contrast, the parent aminoglycoside was non-toxic in vitro (Huang MY and Schacht J, Biochem Pharmacol 40: R11-R14, 1990). In the present study, we investigated the subcellular distributi...
In this work the selectivity of crosslinked organic solvent stable PBI membranes is tuned by varying molar ratio two grafting agents: a long flexible polymer modifier (Elastamine RE-1-1000, 1000 g mol-1) and small molecule (2-methoxyethylamine, 75 mol-1). Grafting exclusively with chain provided membrane molecular weight cut-off (MWCO) 2000 mol-1 in acetonitrile. Increasing proportion reaction ...
