I briefly review the current status of quantum gravity. After giving some general motivations for the need of such a theory, I discuss the main approaches in quantizing general relativity: Covariant approaches (perturbation theory, effective theory, and path integrals) and canonical approaches (quantum geometrodynamics, loop quantum gravity). I then address quantum gravitational aspects of stri...

Protein conjugates of pyridoxal have been used to elicit anti-vitamin B6 antibodies in rabbits. These antibodies have been incorporated into 2 homogeneous assays systems, a spin immunoassay, using a paramagnetic derivative of the vitamin as ligand, and a fluorescence enzyme immunoassay, using beta-galactosidase conjugated to vitamin B6 as the indicator molecule. These assay systems do not requi...

Refeeding oedema in patients with anorexia nervosa is a known but yet under-reported and poorly-understood condition. We illustrate this condition in a 19-year-old girl with anorexia nervosa who developed bipedal oedema after she was started on nutritional therapy. It is important to be aware of the differential diagnoses of oedema in such cases, which includes heart failure and previous diuret...

introduction: a challenge for health care providers is that there will be a distinct rise globally in the number of elderly people aged 80 years and over. malnutrition is a well-known problem among elderly people. the aim of this study was to determine nutritional status and its associated risk factors in elderly nursing home residents in tehran, iran. methods: the cross-sectional study was car...

the nutrients are able to interact with molecular mechanisms and modulate the physiological functions in the body. the nutri­tional genomics focuses on the interaction between bioactive food components and the genome, which includes nutrigenet­ics and nutrigenomics. the influence of nutrients on f genes expression is called nutrigenomics, while the heterogene­ous response of gene variants to nu...

results a relatively strong positive correlation was found between the knowledge development approach, nutritional science, nutrition education and research, and proper solutions for individual nutritional problems and a culture of nutrition (p < 0.001). conclusions 1) effective enhancement and participation in an academic community will be important in the future of food and nutrition security...

Protein compositional data can address nutritional, packaging, origin/authenticity, processing history, safety and other quality questions. Such data has been time-consuming and expensive to generate until recently but "protein analysis on a chip" systems are now available that can analyze a complex food sample in a few minutes and do not require great protein analytical expertise. We review so...

Overweight and obesity in children and adolescents represent a serious public health problem in Peru, with high costs for society that require the implementation of a set of public policies directed toward its control. Thus, interventions have been proposed as the regulation of advertising of unhealthy foods, self-regulation, the implementation of kiosks healthy and nutritional labeling. From t...

This review describes theories of human atherogenesis and experimental results evaluating gene or protein expression in the pigeon model for spontaneous atherosclerosis. The spontane‐ ous disease in the pigeon differentiates from other animal models that require manipulation (genetic, nutritional, environmental) to induce the disease state. Both susceptible and resistant pigeons have been studi...
