The aim of this experiment was to study 15N and amino-nitrogen (AN) portal absorption in the growing pig after ingestion of uniformly (0.2509 APE) labelled 15N milk (M), yogurt ingested just after manufacturing (Y0), yogurt stored for 21 d at 4 degrees C (Y21) and heat-treated yogurt (HY). The highest porto-arterial differences (PAD) in 15N and AN were found in the period between 30 min and 90 ...

Exposure to alcohol in utero can induce a variety of physical and mental impairments, collectively known as fetal alcohol spectrum disorders (FASD). This study explores the persistent cognitive consequences of ethanol administration in rat pups over postnatal days (PD) 4-9, modeling human third trimester consumption. Between PD65-70, ethanol-exposed (5E) and control rats were evaluated in two v...

A total of 719 wild rats were captured from four localities representing the west (Kuala Lumpur), east (Kuantan), north (Georgetown) and south (Malacca) to determine the diversity of blood protozoan from the urban wild rat population in peninsular Malaysia. Five rat species were recovered with Rattus rattus diardii being the most dominant species, followed by Rattus norvegicus, Rattus exulans, ...

chemistry Nitrosamines (NAs) are a family of chemical compounds discovered over 100 years ago. It was not until the 1950s that these compounds received worldwide attention. In the 1950s, two British scientists, Barnes and Magee discovered that dimethylnitrosamine is a powerful carcinogen in laboratory animals. This finding led to massive studies involving NAs in many industries throughout the y...

So far, we have been concerned with nonparametric tests and procedures: tests and procedures with minimal assumptions about the probability distribution that gives rise to the data. Examples of the kinds of assumptions we have made in various places are that the distribution is continuous, that the observations are iid, that subjects are randomized into treatment and control, etc. We now consid...

Human behavior is mostly composed of habitual actions that require little conscious control. Such actions may become invalid if the environment changes, at which point individuals need to switch behavior by overcoming habitual actions that are otherwise triggered automatically. It is unknown how the brain controls this type of behavioral switching. Here we show that the presupplementary motor a...

Pyridostigmine bromide (PB) is a reversible cholinesterase inhibitor. The aim of this study was to determine the effect of orally administration of single dose sustained-released tablet of pyridostigmine bromide (PBSR) on the frequency domain indices of heart rate variability (HRV). Thirty-two healthy young men were participated in this study. They were divided into 2 groups; the pyridostigmine...

palm date leaves were processed with lime in a processing reactor in a factorial arrangement of treatments (3 × 3) with 3 levels of temperatures (40, 80 and 100°c) and time periods (80, 160, and 240 minutes) in a completely randomized design. fermentation parameters measured using gas production technique. with increasing pretreatment time and temperature lignin content reduced from 13.0 percen...

The feeding rate of a parasitic gnathiid isopod on fish was examined. Individual fish, Hemigymnus melapterus, were exposed to gnathiid larvae and sampled after 5, 10, 30, 60, and 240 min. I recorded whether larvae had an engorged gut, an engorged gut containing red material, or had dropped off the fish after having completed engorgement; variation among sampling times and larval stages was anal...

This study assessed whether glucose-dependent insulin secretion and overall counterregulatory response are preserved during hypoglycemia in the presence of exenatide. Twelve healthy fasted volunteers were randomized in a triple-blind crossover study to receive either intravenous exenatide (0.066 pmol. kg(-1). min(-1)) or placebo during a 270-min stepwise hyperinsulinemic-hypoglycemic clamp (ins...
