The present work has been under taken to study the antibacterial activity of stem, leaf, flower and seed extracts of Trichosanthes cucumerina L against disease causing bacteria. Antibacterial activity of different solvent extracts (Aqueous, Methanol, Chloroform, Petroleum ether, Acetone) of stem, leaf, flower and seed of T. cucumerina has been studied to find out their activity against nine pathogenic bacteria viz., Bacillus cereus, Micrococcus luteus, Escherichia coli, Proteus vulgaris, Klebsiella pneumonia, Bacillus sphericus, Salmonella typhimurium, Pseudomonas aeruginosa and Staphylococcus aureus. The antibacterial activity of the extracts of different plant parts was done through well diffusion method and by measuring the inhibition zone around the disc. According to our observations, the seed extracts of T. cucumerina exhibited antibacterial activity against all the bacteria under study. The results provided evidence that the species T. cucumerina can be used as a potential source of antibacterial...

The main objective of this present work was to develop and evaluate matrix tablets of Atenolol by melt granulation technique and compare the drug release between bess wax and glyceryl monostearate (GMS). Polymers like HPMC K 4 M, HPMC K 100 M, bees wax, glyceryl monostearate and ethyl cellulose were incorporated in the formulation. Formulations were prepared by keeping the HPMC and ethyl cellulose at constant ratio. Bees wax and glyceryl monostearate (GMS) were used in different ratios. FTIR studies indicate that there is no interaction between drug and excipients. Developed tablets were evaluated for weight variation, friability, hardness, thickness, drug content, swelling index and drug release profiles. The dissolution studies showed that drug release was better in the formulations where glyceryl monostearate (GMS) is higher than the bees wax. Thus, it was concluded that HPMC K 4 M, HPMC K 100 M along with Bees wax and Glyceryl monostearate can be successfully used in the formulation of Atenolol sustained release gastro retentive floating drug delivery...

Cancer is primarily an environmental disease with 90–95% of cases attributed to environmental conditions and 5–10% due to genetics.RAS proteins act as binary molecular switches and play an important role in intracellular signal transduction which regulates processes such as actin cytoskeletal integrity, proliferation, differentiation, cell adhesion, apoptosis, and cell migration. The present bio-computational analysis was performed using web-based tools and servers. Multiple sequence alignment of selected human RAS subfamily proteins with other homologous sequences revealed highly conserved regions. The present work determined the physico-chemical properties of selected RAS proteins such as their hydrophilic nature; alpha–helical structure and close evolutionary relationship with higher vertebrates. Cancerous proteins (gi166706781, gi 4505451) from human having most of homology with the number of species. On the basis of this study we can suggest that these organisms can be taken for the further study and after the successful analysis, these can be implemented on...

Scope: In recent years, governments and industries worldwide have invested billions of dollars in nanotechnology research and development, and proponents predict that it will offer numerous benefits to society. Objectives: To evaluate the toxicity of Cerium in nanomaterials and in bulk form in rats by repeated daily oral treatment for 28 days by monitoring the effects on animal and also to assess the hematological and various biochemical parameters in serum and targeted biochemical parameters. Results and discussion: The 28 days repeated dose oral toxicity showed CeO2-NM and CeO2-Bulk did not affect the body weight gain and feed intake of the treated rats. Further, CeO2-NM significantly inhibited some of the hematological parameters like platelets count, granulocytes, % hematocrit and biochemical parameters in both male and female rats in dose dependent manner. However, CeO2-Bulk could not induce any significant alterations in these parameters and the changes were near to control in both male and female treated rats. Conclusion: These results suggested that as particle size decreases, showed increased toxicity, even though...

It is well known that main sources of Vitamin D are sun exposure and diet. There is a gap in our knowledge about the contribution of these factors to Vitamin D level among autistic children in Egypt. Aim: To determine Vitamin D dietary intake and sun exposure and their impact on vitamin D level. Methods and procedures: Serum Vitamin D levels were measured in 42 autistic and 40 healthy matched children. Dietary Vitamin D intake and sun exposure hours were collected using an adapted pre-validated food frequency questionnaire. Vitamin D intake was compared with recommended dietary intake (600 IU). Results and outcomes: Autistic children had significantly lower serum levels of 25- hydroxy Vitamin D than healthy children (P < 0.001) with 54.7% and 28.6% being Vitamin D deficient and insufficient, respectively. Dietary Vitamin D intake of both groups was significantly lower than recommended dietary intake. No correlations between serum Vitamin D level and dietary Vitamin D intake or Childhood Autism Rating Scale. Conclusion and implications: Vitamin D deficiency was...
