However, many complex factors might affect in vivo extrapolation selleck inhibitor results.”
“Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that selectively affects the motor neurons of the brain and spinal cord. ALS occurs in about 1 in 100,000 individuals. Although recent advances have been made in understanding the pathogenesis of ALS, there has been no new effective pharmacotherapy since the approval of riluzole more than 10 years
ago. The mainstay of clinical management includes pharmacologic management of symptoms, management of dysphagia and respiratory symptoms, palliative care, and multidisciplinary care clinics. In this review, we discuss the clinical management of ALS, recent modifications to the diagnostic criteria, and current clinical trials.”
“High performance liquid chromatography (HPLC) methods for determination of organosulfur compounds (OSCs) before their enzymatic decomposition and allicin in garlic were optimized and validated. Four gamma-glutamyl peptides,
2 S-alk(en)yl cysteine sulfoxides, and 2 S-alk(en)yl cysteine were simply extracted with water, followed by the sensitive and selective determination of all compounds in a single run using reverse phase HPLC. Allicin was extracted with dichloromethane and diethyl ether and analyzed by normal phase HPLC/UV system. OSCs and allicin were separated on Hypurity Elite C(18) and silica gel column, respectively. These methods exhibited excellent linearity for all of the GDC-0994 MAPK inhibitor analytes with good find more correlation coefficient (r>0.984). Average recoveries were in the range of 81.89-102.38% with good standard
deviations. The limits of quantitation (LOQs) of OSCs and allicin ranged from 0.76 to 5.79 and 20.09 mu g/mL, respectively. The precision results were expressed as relative standard deviation (RSD), ranged from 0.03 to 3.31% for intra-day and from 1.22 to 14.00% for the inter-day. These analytical methods and validation data may be useful for quality evaluation of garlic bulbs.”
“The antimicrobial activity of the methanolic crude extract, the ethyl acetate and n-buthanol fractions and the isolated substances ( iriflophenone 2-O-beta-D-glucoside and 3-O-methyl-chiro-inositol) was studied using the microdilution method and determination of minimal inhibitory concentration ( MIC) value. The results obtained with Calliandra umbellifera Benth. extract and fractions showed a strong antibacterial activity, with MIC between 128 and 256 mu g/mL for all bacterial strains and no antifungal activity; however, the isolated substances showed strong antifungal activity against Candida albicans and Candida krusei and no antibacterial activity. This is the first study reporting the biological properties of C. umbellifera.
