This study was conducted to evaluate the effect of different levels of sunflower meal (SFM) and niacin on laying hens performances, biochemical parameters, antioxidant status, and egg yolk cholesterol concentration. A total of 960, White Leghorn (Hy-Line W-36) commercial layers were randomly assigned to 12 groupsof 8 replicates with 10 hens each. Hens were allocated to diets 1 through 12 in a 3...

Niacin is an important therapeutic option for the treatment of dyslipidemias and is the only agent currently available that favorably affects all components of the lipid profile to a significant degree. Niacin has consistently been shown to significantly reduce levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and lipoprotein (a), while having the greatest h...

Treatment with niacin effectively improves multiple lipid parameters and cardiovascular outcomes. Widespread use of niacin, however, is limited by flushing, which is mediated primarily by prostaglandin D2 (PGD2). Laropiprant is a selective PGD2 receptor 1 (DP1) antagonist that reduces objective measures of niacin-induced flushing symptoms upon initiation of therapy and with more chronic use. Re...

Due to the incorporation of niacin into the coenzymes NAD and NADP, niacin is of great importance for the metabolism of man and animals. Apart from niacin in feed and endogenous formation, microbial niacin synthesis in the rumen is an important source for dairy cows. But the amount synthesised seems to differ greatly, which might be influenced by the ration fed. Many studies revealed a positive...

Niacin, also known as nicotinic acid, is an organic compound that has several cardio-beneficial effects. However, its use is limited due to the induction of a variable flushing response in most individuals. Flushing occurs from a niacin receptor mediated generation of prostaglandins from arachidonic acid metabolism. This study examined the ability of docosahexaenoic acid, eicosapentaenoic acid,...

this experiment was conducted to examine effects of different levels of niacin on the gut and liver histology and also some activity of the liver enzymes in the blood serum of common carp. a control diet (containing 30 mg niacin kg-1 commercial diet) and four other diets were prepared which had 50, 70, 90 and 110 mg niacin per kg of commercial diet, added by spraying. fish with initial average ...

It is well known that niacin deficiency manifests with several psychiatric manifestations. Also historically evidence has accumulated that niacin augmentation can be used for treatment of schizophrenia. However, the etiopathological associations between niacin deficiency and schizophrenia as well as the mechanism of action of niacin in its treatment. More importantly, the subgroups of schizophr...

Although coagulopathy is a well-known complication of severe niacin-induced hepatotoxic reaction, it is not found in patients with minimal aminotransferase level elevations. Three patients with significant clotting factor synthesis deficiency and coagulopathy (prothrombin times, greater than 1.5 times control) from sustained-release niacin had only mild aminotransferase level elevations (1.5 to...

BACKGROUND Abuse-deterrent formulations attempt to address public health and societal concerns regarding opioid abuse. Oxycodone HCl-niacin tablets combine oxycodone HCl with niacin and functional inactive excipients to create potential barriers to oral, intranasal, and intravenous abuse. This study compared the relative abuse potential of oral immediate-release oxycodone HCl-niacin with that o...
