In patients with moderate, dietary noncorrigible hyperlipoproteinemia type IIb and ischemic heart disease, treatment with nicotinic acid is limited by the side effects of the drug. In 100 patients, 6-month treatment with nicotinic acid (n = 50) or "essential" phospholipids (EPL); Lipostabil, manufacturer: Rhône-Poulenc Rorer) (n = 50) indicated comparable efficacy for both substances: Significant (p < .001) reductions of serum total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride values were similar in both groups, while nicotinic acid increased high-density lipoprotein (HDL) cholesterol significantly (p < .01) better than Lipostabil. A detailed analysis of ultracentrifugal lipoprotein profiles, hydroperoxide concentrations in LDL, and cholesterol-accepting properties of HDL in a small number of Lipostabil- and nicotinic acid-treated patients revealed favorable shifts in the lipoprotein profile, significant (p < .05) reductions of LDL hydroperoxides, and favorable increases of the most antiatherogenic HDL2b subfraction only in the Lipostabil-treated group. Clinically, both medications reduced the intensity and number of angina pectoris attacks per week (p < .05), but only Lipostabil-treated patients significantly (p < .05) increased their working capacity in the veloergometric test. Since in the nicotinic acid-treated group dropouts (nine patients, eight related to the drug) and side effects [14] exceeded those in the Lipostabil-treated group (two dropouts not related to the drug, no side effects), it is suggested that Lipostabil is a preferable alternative in the treatment of patients with moderate, dietary noncorrigible hyperlipoproteinemia IIb and ischemic heart disease.

Nicotinamide adenine dinucleotide phosphate hydrate dehydratase (NAXD) and nicotinamide adenine dinucleotide phosphate hydrate epimerase (NAXE) deficiencies are rare autosomal recessive metabolic disorders characterized by severe neurological manifestations during infancy. In affected individuals, febrile illnesses can trigger progressive encephalopathy often accompanied by distinctive skin eruptions, resulting in high mortality rates. This study reviews the literature on NAXD/NAXE deficiencies, focusing on dermatological manifestations and their correlation with genotypic variations and treatment responses.

Nicotinamide (NAM), a main precursor of NAD+, is essential for cellular fuel respiration, energy production, and other cellular processes. Transporters for other precursors of NAD+ such as nicotinic acid and nicotinamide mononucleotide (NMN) have been identified, but the cellular transporter of nicotinamide has not been elucidated. Here, we demonstrate that equilibrative nucleoside transporter 1 and 2 (ENT1 and 2, encoded by SLC29A1 and 2) drive cellular nicotinamide uptake and establish nicotinamide metabolism homeostasis.

Objective: To characterize food group consumption, assess the contribution of food groups to energy and micronutrient intake, and estimate usual nutrient intake among adults in rural Sri Lanka.

Design: A baseline survey (Dec 2020-Feb 2021) was conducted as part of an agriculture-based, nutrition-sensitive resilience program evaluation. Dietary intake was assessed using telephone-based 24-hour recalls (n=1283), with repeat recalls from 769 participants.

Conusvenoms are composed of peptides that are commonly post-translationally modified, increasing their chemical diversity beyond what is encoded in the genome and enhancing their potency and selectivity. This study describes how PTMs alter an α-conotoxin's selectivity for specific nAChR subtypes. Venom from the cone snailConus(Asprella)neocostatuswas fractionated using high-performance liquid chromatography and tested using a behavioral intracranial mouse bioassay and a cholinergic calcium imaging assay using SH-SY5Y neuroblastoma cells.

Objectives: Increased nuclear factor (NF-kβ) and carbonyl stress due to decreased glyoxalase-1 activity (Glo-I) contribute significantly to insulin resistance and vascular complications. Therefore, we aimed to study the impact of the combination of thiamine and niacin on hepatic NF-kβ signaling, metabolic profile, and Glo-I activity in male rats with type-2 diabetes (T2DM).

Materials And Methods: Forty male rats were divided equally into five groups: control, diabetic, diabetic treated with thiamine (180 mg/l in drinking water), niacin (180 mg/l), and a combination of both.
