Epigenetic Regulation of Nuclear Factor Erythroid-2-Related Factor 2 in Colorectal Cancer Cells Resistant to Ionizing Radiation.

γ-Radiation resistance is a major obstacle to the success of radiotherapy in colorectal cancer. Antioxidant-related factors contribute to resistance to radiation therapy and, therefore, are targets for improving the therapeutic response. In this study, we evaluated the molecular mechanisms underlying γ-radiation resistance using the colorectal cancer cell line SNUC5 and γ-radiation-resistant variant SNUC5/RR, including analyses of the role of nuclear factor erythroid 2-related factor 2 (NRF2), a transcription factor that regulates antioxidant enzymes, and related epigenetic regulators.

COVID-19 may Enduringly Impact cognitive performance and brain haemodynamics in undergraduate students.

To date, 770 million people worldwide have contracted COVID-19, with many reporting long-term "brain fog". Concerningly, young adults are both overrepresented in COVID-19 infection rates and may be especially vulnerable to prolonged cognitive impairments following infection. This calls for focused research on this population to better understand the mechanisms underlying cognitive impairment post-COVID-19.

Proteomic and cytokine profiling of a CTRP8-RXFP1 glioma mouse model.

Glioblastoma (GB) is the most prevalent and aggressive primary brain tumor with fatal outcome due to a lack of effective treatments. We previously identified C1q-tumor necrosis factor-related protein 8 (CTRP8), a new member of the adiponectin family, as a novel agonist of the relaxin family peptide receptor 1 (RXFP1) and showed that the CTRP8-RXFP1 ligand-receptor system facilitates increased invasiveness and chemoresistance in GB cells. In the present study, we have investigated the role of the CTRP8-RXFP1 signaling axis in glioma progression using an orthotopic mouse model xenografted with human U251 glioma cells stably expressing CTRP8 and RXFP1.

Development of tetracycline analogues with increased aqueous stability for the treatment of mycobacterial infections.

Tetracycline analogs from the minocycline family have recently shown promise for the treatment of non-tuberculous mycobacterial infections. However, current tetracycline and minocycline therapeutics can be limited by tolerability, stability, or inactivation by TetX. In this study, a series of novel 9-heteroaryl substituted minocycline analogs were designed and synthesized, which resulted in analogs with good in vitro activity against Mycobacterium tuberculosis and Mycobacterium abscessus, stability in water for more than 7 days, avoidance of TetX inactivation in M.

Extensive Secondary Cratering From the InSight Sol 1034a Impact Event.

Impact cratering is one of the fundamental processes throughout the history of the Solar System. The formation of new impact craters on planetary bodies has been observed with repeat images from orbiting satellites. However, the time gap between images is often large enough to preclude detailed analysis of smaller-scale features such as secondary impact craters, which are often removed or buried over a short time period.

Factors affecting women's access to primary care in the United States since the Affordable Care Act: A mixed-methods systematic review.

Background: In the United States, the Affordable Care Act (ACA) expanded public and private health coverage, increased health insurance affordability, reduced healthcare costs, and improved healthcare quality for many. Despite ACA provisions, lack of insurance and other factors continue to affect working-age women's access to primary care services.

Methods: We conducted a mixed-method systematic review to identify factors that affect women's access to primary care services since the ACA.

Gut microbiota profiling in injection drug users with and without HIV-1 infection in Puerto Rico.

Introduction: The full extent of interactions between human immunodeficiency virus (HIV) infection, injection drug use, and the human microbiome is unclear. In this study, we examined the microbiomes of HIV-positive and HIV-negative individuals, both drug-injecting and non-injecting, to identify bacterial community changes in response to HIV and drug use. We utilized a well-established cohort of people who inject drugs in Puerto Rico, a region with historically high levels of injection drug use and an HIV incidence rate disproportionately associated with drug use.

Safety and efficacy of ketamine use in patients with vaso-occlusive crisis: A systematic review and meta-analysis.

Introduction: Sickle cell disease (SCD) is characterized by acute episodes called vaso-occlusive crises (VOC). VOC is marked by severe pain due to blocked blood vessels by sickled cells. Ketamine has been reported to be effective and safe in managing VOC in SCD patients.

C-Peptide Ameliorates Particulate Matter 2.5-Induced Skin Cell Apoptosis by Inhibiting NADPH Oxidation.

Roadmap for the evolution of monitoring: developing and evaluating waveform-based variability-derived artificial intelligence-powered predictive clinical decision support software tools.

Background: Continuous waveform monitoring is standard-of-care for patients at risk for or with critically illness. Derived from waveforms, heart rate, respiratory rate and blood pressure variability contain useful diagnostic and prognostic information; and when combined with machine learning, can provide predictive indices relating to severity of illness and/or reduced physiologic reserve. Integration of predictive models into clinical decision support software (CDSS) tools represents a potential evolution of monitoring.
