“BACKGROUND: The effectiveness of therapies that raise high-density lipoprotein cholesterol (HDL-C) to lower cardiovascular disease risk is currently under debate, Selisistat in vitro and further research into the relationship between HDL-C and function is required.

OBJECTIVE: o investigate whether 2 established HDL-C-raising therapies had differential effects on parameters of high-density lipoprotein (HDL) quality and function, such as HDL particle profile and cholesterol efflux capacity (CEC), in patients with dyslipidemia.


AND RESULTS: Sixty-six patients with dyslipidemia, 24 with low HDL-C levels (<40 mg/dL) and 42 with normal HDL-C levels (40-59 mg/dL), were treated for 6 weeks with fenofibrate (160 mg/d) or extended-release (ER) niacin (0.5 g/d for 3 weeks, then 1 g/d) with 4 weeks of washout between treatments. Lipoprotein particle size distribution was determined using nuclear magnetic resonance, and pathway-specific serum CECs were assessed in J774 macrophages, hepatoma, and Chinese hamster ovary human adenosine triphosphate-binding cassette transporter G1 cells. Comparable increases in HDL-C and apolipoprotein A-I levels were seen with fenofibrate and ER niacin. There was a shift toward larger HDL, predominantly to medium-size HDL particles for fenofibrate (+209%) and to large HDL particles for ER niacin (+221%). Minor changes in serum CECs were observed with fenofibrate and ER niacin for all

the efflux pathways measured. Small increases in plasma cholesteryl ester transfer Ispinesib protein and lecithin: cholesterol acyltransferase concentrations, and decreases in cholesteryl ester transfer protein activity were seen with both drugs.

CONCLUSIONS: Fenofibrate and ER niacin increased plasma HDL-C level similarly,

but modulated HDL particle size distribution differently; however, these changes did not result in differential effects on serum CECs. (c) 2013 National Lipid Association. All rights reserved.”
“A female, eight-year-old, mixed-breed blue-eyed dog was presented for ophthalmic evaluation because its left eye had changed color one year previously. The before Vactosertib solubility dmso left eye was enucleated and submitted for evaluation. Histopathological analysis revealed an invasive neoplastic mass effacing most of the ventral aspect of the iris stroma. A diagnosis of an anterior uveal spindle cell tumor was made. Immunohistochemical results were strongly suggestive of a schwannoma, but some smooth muscle differentiation was also observed. Two and a half years after therapeutic enucleation there was no evidence of neoplasm recurrence or metastasis.”
“OBJECTIVES: To assess the diversity of Mycobacterium tuberculosis strains in Cotonou, Benin, and the risk factors associated with clustering.

METHODS: We analysed one sputum sample from 194 consecutive new pulmonary tuberculosis (TB) cases using two genotyping methods: spoligotyping and the 12 loci mycobacterial interspersed repetitive unit-variable number of tandem repeats (MIRU-VNTR).
