Background Due to significant increases in the prevalence of overweight and obesity in adolescents in developed countries, much attention has been focused on this issue. This study aimed to determine the effectiveness of nutritional education based on Health Belief Model (HBM) on self-esteem and body mass index (BMI) of overweight and at risk of overweight adolescent girls. Materials and Method...

Tick-borne hemorrhagic fever viruses (TBHFV) are detected throughout the African and Eurasian continents and are an emerging or re-emerging threat to many nations. Due to the largely sporadic incidences of these severe diseases, information on human cases and research activities in general have been limited. In the past decade, however, novel TBHFVs have emerged and areas of endemicity have exp...

چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...

Access to nutrients is a key factor governing development, reproduction and ultimately fitness. Within social groups, contest-competition can fundamentally affect nutrient access, potentially leading to reproductive asymmetry among individuals. Previously, agent-based models have been combined with the Geometric Framework of nutrition to provide insight into how nutrition and social interaction...

OBJECTIVES Data on acute geriatric patients' nutritional status are lacking, and the associations among physical function, sarcopenia, health status and nutritional status are not sufficiently investigated in this population. The aims of this study are to investigate (1) nutritional status and sarcopenia in a group of acute geriatric patients, (2) the association between nutritional status, phy...

PURPOSE Elderly cancer patients are at increased risk for malnutrition. We aim to identify comprehensive geriatric assessment (CGA) based clinical factors associated with increased nutritional risk and develop a clinical scoring system to identify nutritional risk in elderly cancer patients. PATIENTS AND METHODS CGA data was collected from 249 Asian patients aged 70 years or older. Nutritiona...

Preclinical research is the initial prerequisite to determining the efficacy of an implant for eventual translation into the clinical arena. Once a spinal implant has been validated through benchtop mechanical testing, analytical modeling, and in vitro evaluation, it is often useful to conduct an in vivo study using animal models to assess the interactions of the living tissue environment surro...

PURPOSE OF REVIEW The impact of neonatal nutrition on the health status of the newborn and incidence of disease in later life is a topic of intense interest. Animal models are an invaluable tool to identify mechanisms that mediate the effect of nutrition on neonatal development and metabolic function. This review highlights recently developed animal models that are being used to study neonatal ...

Mechanistic models of ruminant digestion and metabolism have advanced our understanding of the processes underlying ruminant animal physiology. Deterministic modeling practices ignore the inherent variation within and among individual animals and thus have no way to assess how sources of error influence model outputs. We introduce Bayesian calibration of mathematical models to address the need ...

Dengue virus remains the most important arbovirus worldwide, and dengue disease poses a significant public health threat. Infection by one dengue serotype does not produce life-long protection against the other three serotypes, and severe disease may be due to non/poorly-neutralizing antibodies to heterologous or homologous dengue serotypes. As such, development, validation, and implementation ...
