Cerebrovasc Dis 2021 Sep 22:1-4. Epub 2021 Sep 22.

Department of Neurosurgery, Stanford School of Medicine, Stanford, California, USA.

Background: The coronavirus disease 2019 (COVID-19) pandemic heralded a number of indirect perturbations to patient behavior and disease epidemiology, and mounting evidence suggests that the COVID-19 pandemic may have exacerbated underlying health disparities along racial and socioeconomic (SES) groups for acute ischemic stroke (AIS).

Cancer Genet 2021 Aug 28;258-259:61-68. Epub 2021 Aug 28.

University of California at San Francisco, San Francisco, CA, USA; Dana-Farber Cancer Institute and Brigham and Women's Hospital, Boston, MA, USA. Electronic address:

Background: High tumor mutation burden (TMB) and total mutation count (TMC) can be predictive of better response to immune checkpoint blockade (ICB). Nevertheless, TMB and TMC are limited by variation across cancers and inconsistent definitions due to different profiling methods (targeted vs whole genome sequencing). Our objective was to identify genomic alterations (GAs) associated with ICB response and builds a novel genomic signature predictive of ICB response, independent of TMB/TMC. Read More

Behav Brain Res 2021 Sep 19:113591. Epub 2021 Sep 19.

University of Maryland School Institute of Human Virology; University of Maryland School of Medicine.

HIV-related neurocognitive impairment can be worsened by cigarette smoking and be more severe in women. Therefore, we analyzed the effects of sex on behavioral function in HIV transgenic (Tg) rats that were exposed to either nicotine alone, to smoke from either nicotine-containing or nicotine-free cigarettes, or non-exposed. The animals were then assessed on the open field test for the total distance traveled and for the fraction of the total distance traveled and the total time spent in the center of the field, and the results then compared to WT rats subjected to the same exposures and testing.

New fractionations in breast cancer: a dosimetric study of 3D-CRT versus VMAT.

J Med Radiat Sci 2021 Sep 22. Epub 2021 Sep 22.

Dipartimento di Diagnostica per Immagini, Radioterapia Oncologica ed Ematologia, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Roma, Italy.

Introduction: Adjuvant radiation therapy (RT) following primary surgery in women affected by early breast cancer (EBC) plays a central role in reducing local recurrences and overall mortality. The FAST-FORWARD trial recently demonstrated that 1-week hypofractionated adjuvant RT is not inferior to the standard schedule in terms of local relapse, cosmetic outcomes and toxicity. The aim of this in silico study was to evaluate the dosimetric aspects of a 1-week RT course, administered through volumetric modulated arc therapy (VMAT), compared with traditional three-dimensional conformal radiation therapy (3D-CRT) with tangential fields.

NS398 as a potential drug for autosomal-dominant polycystic kidney disease: Analysis using bioinformatics, and zebrafish and mouse models.

J Cell Mol Med 2021 Sep 22. Epub 2021 Sep 22.

Division of Nephrology, Kidney Institute of People's Liberation Army (PLA), Changzheng Hospital, Second Military Medical University, Shanghai, China.

Autosomal-dominant polycystic kidney disease (ADPKD) is characterized by uncontrolled renal cyst formation, and few treatment options are available. There are many parallels between ADPKD and clear-cell renal cell carcinoma (ccRCC); however, few studies have addressed the mechanisms linking them. In this study, we aimed to investigate their convergences and divergences based on bioinformatics and explore the potential of compounds commonly used in cancer research to be repurposed for ADPKD.
