Background: Meat intake may be related to weight gain because of its high energy and fat content. Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results. Objective: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain a...
Human medicine is continuously developing, and human medical model is also constantly evolving. In the evolution process of medical model, medical humanistic spirit is constantly developing as well. In order to build modern medical humanistic spirit, grasp of the evolution of human medical model as well as the development course of medical humanistic spirit is highly necessary. In this paper, t...
Systemic lupus erythematosus (SLE) is a multi-system inflammatory disease where genetic susceptibility coupled with largely undefined environmental factors is reported to underlie the aetiology of the disease. One such factor is low vitamin D status. The primary source of vitamin D is endogenous synthesis following exposure of the skin to UVB light. Photosensitivity, sunlight avoidance and the ...
Poloxamers are triblock copolymers with a center block of hydrophobic polypropylene oxide (PPO) flanked by two hydrophilic polyethyleneoxide (PEO) blocks. Among this family of copolymers, poloxamer 407 is a non-ionic surfactant with reversible gelation properties above a particular polymer concentration and a particular temperature. Easy preparation of poloxamer 407 based sterile injectable for...
Insights into the proteome reactivity of electrophiles are crucial for designing activity-based probes for enzymes lacking cognate affinity labels. Here, we show that different classes of carbon electrophiles exhibit markedly distinct amino acid labeling profiles in proteomes, ranging from selective reactivity with cysteine to adducts with several amino acids. These data specify electrophilic c...
The present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (PA) that can be used for the preparation of immediate release pellets formulation. Two commercially available grades poloxamer 188 (P 188) and poloxamer 407 (P 407) were selected, and solid dispersions (SDs) conta...

Poloxamer 407 (P-407) is a copolymer surfactant that induces a dose-controlled dyslipidemia in both mice and rats. Human macrophages cultured with P-407 exhibit a concentration-dependent reduction in cholesterol efflux to apolipoprotein A1 (apoA1) linked to downregulation of the ATP-binding cassette transporter A1 (ABCA1). Activators of peroxisome proliferator-activated receptor gamma (PPARgamm...
Supraphysiological increases in serum triglycerides and cholesterol often occur during pregnancy, but their effects on vascular function are poorly understood. Intraperitoneal injection of the nontoxic surfactant poloxamer 407 (P-407) results in sustained elevation of triglycerides and cholesterol. We asked if P-407-induced hyperlipidemia during late pregnancy adversely affects mesenteric resis...
