Highly versatile small virus-encoded proteins in cellular membranes: A structural perspective on how proteins' inherent conformational plasticity couples with host membranes' properties to control cellular processes.

We investigated several small viral proteins that reside and function in cellular membranes. These proteins belong to the viroporin family because they assemble into ion-conducting oligomers. However, despite forming similar oligomeric structures with analogous functions, these proteins have diverse amino acid sequences.

Doctors' satisfaction with the rehabilitation system for anti-terrorist operation participants: A factor analysis.

Background: A war has a catastrophic effect on veterans' health. However, there is a knowledge gap about the veterans' rehabilitation system, requirements, and the satisfaction of doctor-organizers. The present study aims to assess the level of satisfaction of the doctor-organizers of health care with the existing rehabilitation system for anti-terrorist operation (ATO) veterans in Ukraine.

Is calcification integral to enthesopathy and tendinopathy rather than a separate disease process?

Background: The pathophysiology of enthesopathy and tendinopathy is mucoid degeneration, which includes chondroid metaplasia. The chondroid metaplasia can be associated with calcification. Inflammation is typically absent unless calcification triggers a self-limited immune response representing acute calcific tendinitis.

Mothering matters: Towards a better understanding of disrupted infant-caregiver relationships in both mother and offspring.

The mother-infant bond is among the strongest social relationships formed in humans and nonhuman mammals. As such, disrupted infant-caregiver relationships have the capacity to result in potent adverse effects not only in the offspring, but also in the mother. Here, I provide a brief overview of my prior work showing adversity-induced alterations in offspring and maternal behavioral and brain function.

Drug-Linker Constructs Bearing Unique Dual-Mechanism Tubulin Binding Payloads Tethered through Cleavable and Non-Cleavable Linkers.

Antibody-drug conjugates (ADCs) have advanced as a mainstay among the most promising cancer therapeutics, offering enhanced antigen targeting and encompassing wide diversity in their linker and payload components. Small-molecule inhibitors of tubulin polymerization have found success as payloads in FDA approved ADCs and represent further promise in next-generation, pre-clinical and developmental ADCs. Unique dual-mechanism payloads (previously designed and synthesized in our laboratories) function as both potent antiproliferative agents and promising vascular disrupting agents capable of imparting selective and effective damage to tumor-associated microvessels.

The dual impact of education and occupation on cognitive functioning in older Mexican adults: A cross-sectional exploratory study.

This research investigated the relationship between cognitive performance and an individual's educational attainment as well as occupational mental demands among Mexican adults aged 50 or older. We hypothesized that cognitively demanding work boosts cognitive performance for older adults regardless of their education level. To test our hypothesis, we analyzed data on 12,939 individuals in the 2012 Mexican Health and Aging Study using a Generalized Linear Model with a Gaussian family and identity link function.

Nanofibrous Peptide Hydrogels Leveraging Histidine to Modulate pH-Responsive Supramolecular Assembly and Antibody Release.

In this work, we investigate the pH-responsive behavior of multidomain peptide (MDP) hydrogels containing histidine. Small-angle X-ray scattering confirmed that MDP nanofibers sequester nonpolar residues into a hydrophobic core surrounded by a shell of hydrophilic residues. MDPs with histidine on the hydrophilic face formed nanofibers at all pH values tested, but the morphology of the fibers was influenced by the protonation state and the location of histidine in the MDP sequence.

Causal Estimands and Multiply Robust Estimation of Mediated-Moderation.

When studying effect heterogeneity between different subgroups (i.e., moderation), researchers are frequently interested in the mediation mechanisms underlying the heterogeneity, that is, the mediated moderation.

Conquering Overtreatment of DCIS: Lessons from PRECISION.

As we cannot reliably distinguish indolent, low-risk ductal carcinoma in situ (DCIS) from potentially progressive, high-risk DCIS, all women with DCIS diagnosis undergo intensive treatment without any benefit. The PREvent ductal Carcinoma In Situ Invasive Overtreatment Now team was established to unravel DCIS biology and develop new multidisciplinary approaches for accurate risk stratification to tackle the global problem of DCIS overdiagnosis and overtreatment.

Atypical Small Cell Lung Cancer: A New Malignancy Characterized by Chromothripsis, Carcinoid Tumors, and Wild-type RB1 and TP53.

Small cell lung cancer (SCLC) and pulmonary carcinoid tumors are traditionally seen as unrelated, with SCLC linked to smoking and characterized by biallelic loss of RB1 and TP53 and rapid progression. Rekhtman and colleagues upend these assumptions by discovering an "atypical" SCLC that arises in nonsmokers with intact RB1 and TP53 loci, chromothripsis-induced oncogene amplifications on extrachromosomal DNA, and frequent synchronous carcinoid tumors. See related article by Rekhtman et al.

Nerves at Play: The Peripheral Nervous System in Extracranial Malignancies.

The exponential growth of the cancer neuroscience field has shown that the host's immune, vascular, and nervous systems communicate with and influence each other in the tumor microenvironment, dictating the cancer malignant phenotype. Unraveling the nervous system's contributions toward this phenotype brings us closer to cancer cures. In this review, we summarize the peripheral nervous system's contributions to cancer.
