A Microwave-Enhanced Synthesis and Biological Evaluation of N-Aryl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d ]pyrimidin-4-amines
A series of N-aryl-5,6,7,8-tetra-hydrobenzo[4,5]thieno[2,3-d ]pyrimidin-4-amines were synthesized in moderate to good yield by using a microwave-enhanced conditions. The selected compounds were evaluated for their cytotoxic effects (IC50 values) on human pulmonary carcinoma (A549), murine BALB/c spontaneous colon adenocarcinoma (CT26) and human hepatocellular liver carcinoma (HepG2) cell lines in vitro. Amongst these compounds, one compound was found to have the better cytotoxic activity with reference...

4D-QSAR Study of 17β-Hydroxysteroid Dehydrogenase Type 3 Inhibitors
Prostate cancer is one of the most common form of cancer among men, and its incidence has been increasing progressively. Since the prostate depends on androgenic hormones to regulate its growth and development, interference with androgenic biosynthesis are important to control the disease. Thus, in this work, a 4D-quantitative structure-activity relationship (QSAR) receptor independent study was carried out using the Laborat ório de Quimiometria Teórica e Aplicada (LQTA)-QSAR approach and the new...

Opportunities to reduce reoperations and to improve inter-facility profiling after initial breast-conserving surgery for cancer. A report from the NCDB
ConclusionIn the NCDB, significant inter-facility variability exists regardless of case volume, case mix, and risk adjustment. There were fewer reoperations after the SSO-ASTRO guideline. An endorsed target rate of 10% was achieved by only 1 in 4 facilities. The most impactful determinant of reoperation was the facility itself. Thus, all stakeholders should consider participation in improvement activities. Such activities will benefit from risk-adjusted profiling; the relevant adjustors were identified....

Surgical treatment of vulvar cancer: Impact of tumor-free margin distance on recurrence and survival. A multicentre cohort analysis from the francogyn study group
ConclusionThis study did not reveal a significant impact of tumor-free margin distance on recurrence and survival in vulvar cancer. Moreover, the benefit of re-excision seems stronger when tumor-free margins are positive or very close (<3 mm), cases in which invasive or in situ lesions are often present closest to the edge of the specimen.

Imiquimod application at mid and late telogen activated the hair follicle stem cells leading to premature hair cycle entry. Based on quinoline structure, a newly synthesized compound 6b displayed proliferation activity in vitro and in vivo through branch chain replacement and triazole ring cyclization. Toll-like receptors (TLRs) are also critical mediators of the immune system, and their activation is linked...

ConclusionThe overall operative mortality for minimally invasive surgery in gynecologic oncology is 1 in 381 (95% CI 1:306-1:474). For patients with early cervical cancer is 1:2049 (95% CI 1:356-1: 11832), for endometrial cancer with node dissection is 1:195 (95% CI 1:109- 1:349), and for ovarian cancer is 1 in 685 (95% 1:44–1:10971).  There is no difference between the type of MIS approach for patients undergoing any type of gynecologic oncology surgery.

Hypothesis: does adrenalitis caused by immune checkpoint-inhibitors put melanoma patients at an elevated risk for recurrence?
AbstractPrimary adrenal failure (Addison ’s disease) is a rare complication of immune checkpoint inhibitor (ICI) therapy. Untreated – and also sometimes under adequate hydrocortisone replacement therapy – the levels of ACTH (Adrenocorticotropic hormone) and MSH (Melanocyte stimulating hormone) are elevated. This may be a reason for c oncern in patients with malignant melanoma (MM): Melanocortin receptors bind to ACTH and the different isoforms of MSH. For example, the melanocortin 1 receptor (MC1R)...

The reality of cancer patients rely on the diagnosis of cancer at the early stages (either in stage 1 or stage 2). If the cancer is diagnosed in stage 3 or later stages means the changes of survival of the patient will become more critical. Normally, single patient records will generate a huge amount of data if the data could be manage and analyze means to solve many problems for identifying the...

In conclusion, overexpression of H19 improved HMEC-1 cells viability, migration and tube-formation capacity. H19 exerted pro-angiogenic effects possibly by down-regulating miR-181a, and thus activating JNK and AMPK signalling pathways.

AbstractGastrectomy is the mainstay treatment for gastric cancer. To reduce the associated patient burden, minimally invasive gastrectomy was introduced in almost 30  years ago. The increase in the availability of surgical robotic systems led to the first robotic-assisted gastrectomy to be performed in 2002 in Japan. Robotic gastrectomy however, particularly in Europe, has not yet gained significant traction. Most reports to date are from Asia, predominantly co ntaining observational studies. These...
