62 %). Only volume of intervention produced a significant effect between the subgroups.

This review suggests that high volume hypnotherapy is more beneficial than low and should be adopted for GDH. Both high frequency and group interventions are effective in reducing GGS in IBS. However, the sample size is small and more studies are needed to confirm this.

Dehydroepiandrosterone (DHEA), the most abundant steroid hormone in human serum, inhibits proliferation and migration of breast cancer cells, modulating the expression of proteins involved in mesenchymal-epithelial transition (MET). However, the underlying molecular mechanisms are not fully understood. DHEA effects on the triple-negative breast cancer cell line MDA-MB-231 (mesenchymal stem-like) could be exerted by binding to receptors tyrosine kinase (RTKs) and signaling through MEK/ERK and/or PI3K/Akt pathways. In this study, MDA-MB-231 cells were exposed to DHEA in the presence of pharmacological inhibitors of these pathways and a siRNA against PIK3CA gene, which blocks PI3K pathway. Cell proliferation was measured by crystal violet staining, migration by the wound healing and transwell assays, and MET protein expression by western blot. A xenograft tumor growth in nude mice (nu-/nu-) using a siRNA against PI3K was also performed. Results showed that neither of the inhibitors used reverted the antiproliferative activity of DHEA. However, wortmannin and LY294002, inhibitors of the PI3K/Akt pathway, abolished the up- and down-regulation of E- and N-cadherin expression respectively, and inhibition of migration induced by DHEA in MDA-MB-231 cells. The siRNA that blocks the PI3K pathway, abolished the effects of DHEA on proliferation, migration, MET proteins expression and the growth of tumors in nude mice. In conclusion, these results suggest that PI3K/Akt pathway participates in the effects of DHEA on breast cancer cells.Clostridium perfringens (C. perfringens), a prolific toxin-producing anaerobe is an important foodborne pathogen with a huge public health concern. Rapid and on-site detection of C. perfringens is of specific importance in developing countries. In the present study, saltatory rolling circle amplification (SRCA) assay was developed for culture-independent, rapid and visual detection of C. perfringens and evaluated in meat with pork as a model. The specificity of the SRCA assay was ascertained by using 62 C. perfringens and 18 non- C. perfringens strains. The analytical sensitivity of the developed SRCA, conventional and real-time PCR assays were 80 fg, 800 fg and 800 fg DNA per tube, respectively. The limit of detection of the SRCA assay was 80 CFU/g of pork in the absence of enrichment and 8 CFU/g after short enrichment of 6 h. The detection limits of 80 CFU/g and 8 CFU/g of pork were attained within 120 min and 8 h, respectively. Real-world or field relevancy of the developed assay was evaluated by screening 82 raw and processed pork samples. As the developed assay is simple, user-friendly, cost-effective and sophisticated-equipment free, it would be more suitable for on-site testing of C. perfringens in foods. To our information, this is the first report to apply SRCA for the detection of C. perfringens.Beta toxins (CPB) produced by Clostridium perfringens type B and C cause various diseases in animals, and the use of toxoids is an important prophylactic measure against such diseases. Promising recombinant toxoids have been developed recently. However, both soluble and insoluble proteins expressed in Escherichia coli can interfere with the production and immunogenicity of these antigens. In this context, bioinformatics tools have been used to design new versions of the beta toxin, and levels of expression and solubility were evaluated in different strains of E. coli. The immunogenicity in sheep was assessed using the molecule with the greatest potential that was selected on analyzing these results. In silico analyzes, greater mRNA stability (-169.70 kcal/mol), solubility (-0.755), and better tertiary structure (-0.12) were shown by rCPB-C. None of the strains of E. coli expressed rFH8-CPB, but a high level of expression and solubility was shown by rCPB-C. Higher levels of total and neutralizing anti-CPB antibodies were observed in sheep inoculated with bacterins containing rCPB-C. Thus, this study suggests that due to higher productivity of rCPB-C in E. coli and immunogenicity, it is considered as the most promising molecule for the production of a recombinant vaccine against diseases caused by the beta toxin produced by C. perfringens type B and C.The correct choice of formulation buffer is a critical aspect of drug development and is chosen primarily to improve the stability of a protein therapeutic and protect against degradation. find more Amino acids are frequently incorporated into formulation buffers. In this study we have identified and characterized light induced cross-links between the side chain of histidine residues in an IgG4 monoclonal antibody and different amino acids commonly used in formulation buffers. These reactions have the potential to impact the overall product quality of the drug. The structure of each cross-link identified was elucidated using high performance liquid chromatography (HPLC) hyphenated to tandem mass spectrometry (MS/MS) with higher energy collisional dissociation (HCD). Furthermore, we speculate on the role of amino acids in formulation buffers and their influence on mAb stability. We theorize that whilst the adduction of formulation buffer amino acids could have a negative impact on product quality, it may protect against other pathways of photo-degradation.
