Enhancement of Purified Human Colon Cancer-Specific Parasporal Toxin from Bacillus thuringiensis-LDC-501.

Enhancement of Purified Human Colon Cancer-Specific Parasporal Toxin from Bacillus thuringiensis-LDC-501. Curr Microbiol. 2019 Nov 14;: Authors: Grace JJ, Ramani G, Shenbagarathai R Abstract Parasporal inclusion protein of Bacillus thuringiensis-LDC-501 (Bt-LDC-501) exhibits selective cytocidal action towards human colon cancer cells. The yield of this parasporal protein was minimum in the normal culture. In order to increase the yield of protein from Bt-LDC-501 various agro-based cost-efficient nutrient sources such as corn steep liquor (CSL), sesame oil cake extract (SOC), groundnut oil cake extract (GOC), neem oil cake extract (NOC), rice bran extract (RB), wheat bran extract (WB), red gram hull extract (RGH), green gram hull extract (GGH), black gram hull extract (BGH), Mysore gram hull extract (MGH), and maize flour waste extract (MFW) were screened. Statistical experimental designs such as Plackett-Burman design (PBD) and response surface methodology (RSM) were the tools employed for the optimization of medium. Groundnut cake extract (GOC) served as a potential carbon and nitrogen source, as it induced twofold higher production of parasporal protein. Among the optimized seven media components KH2PO4, K2HPO4, GOC, NaCl, MgSO4, MnSO4, and FeSO4, the concentrations of GOC, NaCl, and MgSO4 have significant effect on parasporin production as well as cytotoxicity against colon cancer cell line, HCT-116. Bt-LDC-501 was found to produce 0.88 mg/ml of ...

Authors: Kim SY, Lee S, Lee E, Lim H, Shin JY, Jung J, Kim SG, Moon A Abstract There is a wide disparity in the incidence, malignancy and mortality of different types of cancer between each sex. The sex-specificity of cancer seems to be dependent on the type of cancer. Cancer incidence and mortality have been demonstrated as sex-specific in a number of different types of cancer, such as liver cancer, whereas sex-specificity is not noticeable in certain other types of cancer, including colon and lung cancer. The present study aimed to elucidate the molecular basis for sex-biased gene expression in cancer. The mRNA e...

Authors: Dai D, Zhou B, Zhong Y, Jin H, Wang X Abstract The aim of the present study was to use a competing risk model to analyze the prognostic value of mucinous adenocarcinoma (MAC) in patients with colorectal cancer (CRC). An additional aim was to construct nomograms for estimating the 3- and 5-year overall survival (OS) and cancer specific survival (CSS) rates of patients with primary CRC with MAC. The data were extracted from the Surveillance, Epidemiology, and End Results database, and a Multivariate Cox model and competing risk model were applied to assess the OS and CSS. Cox-based and competing risk-based n...

Aspects concerning patient adherence to anti-TNFα therapy in psoriasis: A decade of clinical experience. Exp Ther Med. 2019 Dec;18(6):4987-4992 Authors: Mocanu M, Toader MP, Rezus E, Taranu T Abstract Non-adherence to psoriasis treatment has an important impact in controlling chronic disease evolution and the occurrence of systemic comorbidities. Biologic therapy represents a revolutionary treatment, many of the undesirable psychological and socio-economical consequences of conventional topical or systemic therapies being avoided. Nevertheless, the discontinuation of biological therapy may occur ...

Authors: Shen H, Liao K, Wu W, Yu H, Wu H Abstract A total of six male patients, who had undergone radical cystectomy and sigma-rectum pouch surgery due to bladder cancer (2-5 years previously), developed hyperchloremic metabolic acidosis, hypokalemia and renal dysfunction. The patients underwent urinary undiversion surgery (the pouch was isolated from the intestinal tract, abdominal ostomy was performed, and the sigmoid colon and rectum were reconnected) and blood gas and electrolyte analysis and renal function were compared pre- and post-surgery. Blood hydrocarbonate levels significantly improved 3 months post-su...

Conclusions: This small, qualitative study suggests that older adults familiar with surveillance colonoscopy prefer patient-centered decision-making on when to discontinue testing and want support and information from providers when making choices. The evidence also suggests that participants value provider communication and trust their advice. Future work will use this information to create a larger patient survey on attitudes and beliefs toward surveillance colonoscopy.

CONCLUSIONS: In all the instances, statistical analysis showed that mean mSWAT score before/after SN diagnosis had a significantly difference (p value=0.0037) suggesting that patients with a SN may have a worse clinical outcome. By secreting immunosuppressive cytokines or recruiting immunosuppressive cells, a sort of mutual help between the two neoplasms may be prompted. Our data suggest that SN development in MF patients may be regarded as a worse prognostic marker. PMID: 31804054 [PubMed - as supplied by publisher]

WadaanAbstractRecent trends in anticancer therapy is to use therapeutic agents which not only kill the cancer cell, but are less toxic to surrounding normal cells/tissue. One approach is to cut the nutrient supply to growing tumor cells, by blocking the formation of new blood vessels around the tumor. As the phytochemicals and botanical crude extracts have proven their efficacy as natural antiangiogenic agents with...
