A bioassay procedure for the evaluation of nutritional quality protein in foods is described. This method involves measurement efficiency ratio (grams gain per gram consumed) under standardized conditions. Male rats Wistar strain 20–23 days age are fed ad libitum an otherwise adequate reference diet containing 10% supplied by a standard sample casein. Foods to be assayed added as sole source at expense casein and corn starch maintain level 10%. Protein ratios (P.E.R.'s) calculated after 4...

BackgroundRemote digital health interventions to enhance physical activity provide a potential solution improve the sedentary behaviour, inactivity, and poor health-related quality of life that are typical chronic conditions, particularly for people with kidney disease. However, there is need high-quality evidence support implementation in clinical practice. The Kidney BEAM trial evaluated effect 12-week intervention on life.MethodsIn single-blind, randomised controlled conducted at 11...

Human alpha, pi, and mu class glutathione S-transferases (GSH S-T) have been localized immunohistologically in a variety of organs. Alpha GSH S-T are found principally hepatocytes, proximal convoluted tubules kidney, the deep reticular layer adrenal gland, interstitial cells testis, oxyntic stomach. The pi present relative abundance ductular, as opposed to parenchymal liver, pancreas, salivary glands, kidney. presence tissues certain patients its absence same from other has demonstrated....

This article discusses research capacity building and its relevance for health practitioners using allied professionals (AHPs) as a case example. Allied is term used to represent diverse group of workers, each with discrete clinical focus, whose needs are likely be similar one another other medical nursing professionals. The work AHPs challenges many current paradigms being complex multidisciplinary in nature, often delivered community settings focusing on holistic outcomes. examines some...

Positive contrast radiographic studies of the central nervous system were first reported by Sicard and Forestier in 1922, using Lipiodol (8). Other substances investigated since that time include Abrodil (1), Thorotrast (5), Perabrodil or Diodrast (2), Pantopaque (4, 6, 9, 10, 11), Hypaque (3), various chelate compounds (7). Failures with air, Pantopaque, at stereotaxic surgery suspected midline tumors aroused our interest absorbable positive media. This paper reviews investigations Conray...

Two rapeseed oils with erucic acid contents of 23 and 42%, their hydrogenated products produced under selective non-selective conditions, corn oil, a lard – olive oil mixture were fed to separate groups rats for 4 weeks. Fatty composition dietary carcass fats was determined. The associated lower food intakes body weight gains than the mixture. Small amounts incorporated into fats. It is possible that amount palmitic in too small good balance fatty acids, partially responsible gains.

This trial assessed the feasibility and acceptability of Kidney BEAM, a physical activity emotional well-being self-management digital health intervention (DHI) for people with chronic kidney disease (CKD), which offers live on-demand sessions, educational blogs videos, peer support. In this mixed-methods, multicentre randomised waitlist-controlled internal pilot, adults established CKD were recruited from five NHS hospitals 1:1 to BEAM or waitlist control.

Fourteen patients with rheumatoid arthritis (RA) self rated their pain and stiffness on separate 10 cm visual analogue scales performed bead intubation coordinometry (BIC) six occasions each day for seven consecutive days. In addition, 14 healthy controls matched age sex also BIC measurements according to the same schedule. Data were analysed using least squares cosine vector techniques. Significant circadian rhythms in RA detected pain, stiffness, BIC, BIC. Pain was at 1700 1724. Peak...

There is considerable variability in the susceptibility and progression for COVID-19 it appears to be strongly correlated with age, gender, ethnicity pre-existing health conditions. However, our knowledge, cohort studies of clinically vulnerable groups are lacking. Host genetics has also emerged as a major risk factor COVID-19, variation ACE2 receptor, which facilitates entry SARS-CoV-2 virus into cell, become focus attention. Thus, we interrogated an ethnically diverse National Health...

Abstract Background Physical activity and emotional self-management has the potential to enhance health-related quality of life (HRQoL), but few people with chronic kidney disease (CKD) have access resources support. The Kidney BEAM trial aims evaluate whether an evidence-based physical wellbeing programme (Kidney BEAM) leads improvements in HRQoL CKD. Methods This was a prospective, multicentre, randomised waitlist-controlled trial, health economic analysis nested qualitative studies. In...
