Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in developing countries. Tripartite motif-59 (TRIM59) a member of the TRIM ubiquitin ligase family, is a surface molecule that regulates biological processes such as cell proliferation, apoptosis, and tumorigenesis. Previous studies reported that TRIM59 expression was upregulated in human CRC, however, the expression pattern and role of TRIM59 in benign colorectal lesions remain unclear.

Objective: To appraise clinical outcomes of systematic lymphadenectomy in women with ovarian cancer based on stage, control group and type of chemotherapy.

Study Design: A literature search was conducted on SCOPUS, PUBMED, COCHRANE, MEDLINE, and WEB OF SCIENCE databases. All comparative studies that assess outcomes of systematic lymphadenectomy in patients with ovarian cancer were eligible.

In late 2019, a new virulent coronavirus (CoV) emerged in Wuhan, China and was named as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This virus spread rapidly, causing the coronavirus disease-2019 (COVID-19) pandemic. Bacillus Calmette-Guérin (BCG) is a live attenuated tuberculosis (TB) vaccine, associated with induction of non-specific cross-protection against unrelated infections.

Objective: To create a model for prediction of success of uterine-preserving procedures in women with placenta accreta spectrum (PAS).

Methods: PAS-ID is a multicenter study that included 11 centers from 9 countries. Women with PAS, who were managed between January 1, 2010 and December 31, 2019, were retrospectively included.

Article Synopsis
  • High-intensity focused ultrasound (HIFU) is a non-invasive treatment being evaluated for managing placenta accreta spectrum (PAS).
  • A systematic review of studies up to January 2020 found that HIFU was successful in all tested cases, with an average recovery time for menstruation of about 49 days and no major complications reported.
  • The study emphasizes the need for a unified global research approach to integrate HIFU and other conservative treatment methods into a comprehensive management protocol for PAS.

Colorectal cancer is considered to be one of the major causes of morbidity and mortality all over the world. T Follicular helper (T) and T follicular regulatory (T) cells are specialized providers of T-cells to help B-cells and shaping germinal centers (GC) response. Recent researches reported a high percentage of T and T in different infectious diseases and certain malignancies.

Recently, layered chalcogenide alloys (LCAs) have been extensively investigated for use in various practical applications by selectively controlling the amount of foreign components. However, the alloying behavior of layered chalcogenides has been rarely explored at the atomistic level. Here, we study the microstructural evolution of SnSeS alloys on the atomic scale by combining scanning tunneling microscopy (STM) measurements with first-principles density functional theory (DFT) calculations.
