Chemical, physical, and biological methods have been developed to synthesis nanoparticles but chemical and physical methods are involved in the production of toxic by-products which are hazardous moreover the methods are very expensive. To synthesis stable metal nanoparticles with controlled size and shape, there have been searched for inexpensive, safe, and reliable and “green” approach. The present study reports an environmentally friendly, low cost, novel and rapid method for synthesis of silver nanoparticles. We have developed a green synthetic method for silver nanoparticles using Cassia tora leaf extract which acts as a reducing & capping agent. It was observed that use of Cassia tora leaf extract makes rapid and convenient method for synthesis of silver nanoparticles and can reduce silver ions into silver nanoparticles within few seconds of reaction time. UV-Vis spectrometer uses to monitor the reduction of Ag ions and formation of AgNPs in medium. The morphological studies of the biosynthesized nanoparticles are done using UV-Vis, HRTEM & FESEM techniques FTIR was performed to identify the functional groups...

Stevioside glycosides (SGs) are a class of diterpene glycosides being produced by leaves of Stevia rebaudiana. Stevia is getting agricultural importance due to the production of natural sweetener steviol glycosides, also called as zero-calorie sweeteners. Earlier it was thought that steviol was synthesized from Kaurene via MVA pathway but later on it was concluded that precursors of steviol are actually synthesized via the plastid localized methylerythritol 4-phosphate (MEP) pathway. In total, seventeen enzymes are used in this biosynthetic pathway. Each enzyme plays a significant role in the subsequent production of rebaudioside A and other SGs. In order to understand those enzymes functionally, understanding of those genes evolution basically in the Asteraceae family is highly warranted. In this study, the National Center for Biotechnology Information (NCBI) was searched to retrieve amino acid sequences that encode MEP pathway enzymes homologs. A number of MEP pathway enzymes’ amino acid sequences from the Asteraceae family were phyleticaly analyzed to light the way for the evolution characteristics of sweetener-producing plants homologs. The study is...

The present study deals with the identification of the phytochemical compounds in ethanol, acetone and benzene extracts from polyherbal formulation composed of the bark of Ficus religiosa, the root of Smilax chinensis, seeds of Nigella sativa, the fruit of Emblica officinalis, Terminalia chebula and Terminalia bellerica which is used to treat psoriasis. The bioactive components of different extracts of the polyherbal formulation were determined by liquid chromatography coupled with mass spectroscopy (LC-MS) analysis. LC-MS analysis of the ethanol extract of the polyherbal formulation revealed the presence of the 9 bioactive chemical constituents, 5 phytochemicals in the acetone extract of polyherbal formulation and the benzene extract consist of 4 bioactive compounds. The results of this present study provide scientific support to medicinal uses of the polyherbal formulation. These compounds may exhibit an antipsoriatic activity which can be done in further...

Alcohol use disorders (AUDs) recognized as substantial public health problem. It is grown-up many risk factors influence on alcoholism including social, behavior, an environment, and heredity conditions on the global. Alcuremon preparation was based on medicinal herbs and used for the treatment of alcohol-related disease and alcoholic liver disease in traditional Mongolian medicine. Male Wistar rats were used to induce alcoholic liver disease and chronic ethanol (EtOH) intoxication with neurotransmitter imbalance by oral administration of ethanol (subchronic 30% EtOH 10 ml/kg/day for 14 days and chronic 40% EtOH 7 ml/kg/day for 60 days). Alcuremon 50, 100 and 150 mg/kg were given orally for the same day as ethanol administration days. Some biochemical parameters and liver HE stains were examined in subchronic intoxication with alcoholic liver disease. Chronic ethanol-induced neurotransmitters changes were measured by enzyme-linked immunosorbent assay (ELISA) in brain homogenate of nucleus accumbens (NAc) and ventral tegmental area (VTA). Hippocampus was stained with cresyl violet. Data were expressed as mean ± SD. The difference between the groups was compared...

Background: The association between metabolic syndrome and cognitive impairment is not well established. The aim of the present study was to estimate the prevalence of cognitive impairment in adults with metabolic syndrome (MetS). Methods: Cross-sectional observational study conducted in patients with metabolic syndrome (n=185). All patients were subjected to written informed consent, anthropometric measurements, neuropsychological assessments using Mini-Mental State Examination (MMSE). MetS was diagnosed using the definition by the National Cholesterol Education Program- Third Adult Treatment Plan. The main outcome measure was cognitive impairment (<24 on the MMSE scale). Mean, standard deviation and students t-test were used to carry out the analyses. Results: The prevalence of cognitive impairment in MetS patients was 24%. Patients age ranged between 20-75 years and 45% (n= 83) of them were female. MMSE scores were lower in female patients compared to male, however, the difference was not significant (p=0.06). College graduates had significantly higher MMSE scores than patients with just a high school education (p<0.05). Patients with high levels of triglycerides had significantly lower...
