This study aimed to compare efficacy of the topical 4% nicotinamide and 1% clindamycin gels in these patients. In this randomized, double-blind clinical trial, patients with moderate inflammatory facial acne vulgaris were randomly allocated to receive either topical 4% nicotinamide (n = 40) or 1% clindamycin gels (n = 40) twice daily. In each group, they were further categorized in two subgroups with oily and non-oily types of facial skin. The Cook's acne grade was determined at baseline and at weeks 4 and 8 post treatment. Acne grade decreased from an average of 5.93 ± 0.83 at baseline to 4.03 ± 1.33 at week 4 and 2.08 ± 1.59 at week 8 in nicotinamide receivers, and from an average of 5.70 ± 0.94 at baseline to 3.85 ± 1.66 at week 4 and 2.03 ± 1.53 at week 8 in t... read more..

Correlation between Phylogroups and Intracellular Proteomes of Propionibacterium acnes and Differences in the Protein Expression Profiles between Anaerobically and Aerobically Grown Cells.
Authors: Dekio I, Culak R, Fang M, Ball G, Gharbia S, Shah HN Abstract Propionibacterium acnes is one of the dominant commensals on the human skin and also an opportunistic pathogen in relation to acne, sarcoidosis, prostate cancer, and various infections. Recent investigations using housekeeping and virulence genes have revealed that the species consists of three major evolutionary clades (types I, II, and III). In order to investigate protein expression differences between these phylogroups, proteomic profiles of 21 strains of P. acnes were investigated. The proteins extracted from cells cultured under anaerobic and aerobic conditions were analysed using a SELDI-TOF mass spectrometer, high-resolution capillary gel electrophoresis, and LC-MS/ MS. The SELDI spectral profiles were v...MedWorm Sponsor Message: Find the best Christmas presents and January Sales in the UK with this simple shopping directory. read more..
