Current androgen receptor antagonists under investigation for resistant prostate cancer: progress and challenges.

Introduction: Prostate cancer represents a significant oncological challenge, with its natural history predominantly driven by androgen receptor (AR) signaling. The pivotal role of this pathway underscores the rationale for targeting AR activity in therapeutic strategies. However, the development of resistance mechanisms has highlighted the need for advanced therapies to address the complexity of the castration-resistant status.

The DnaJ1 heat shock protein interacts with the flavanone 3-hydroxylase-like protein F3HL to synergistically enhance drought tolerance by scavenging reactive oxygen species in tomato.

The widely distributed heat shock protein DnaJ is renowned for its pivotal role in enhancing thermal tolerance in plants; however, its involvement in drought tolerance remains elusive. In this study, genes encoding DnaJ1 were cloned from drought-resistant wild tomato (Solanum pennellii) and drought-sensitive cultivated tomato (Solanum lycopersicum). SpDnaJ1 and SlDnaJ1 from both tomato species were localized in the chloroplast, and their gene expression was induced by various abiotic stresses.

The LINC Complex Regulates Tendon Elastic Modulus, Collagen Crimp, and Lateral Expansion During Early Postnatal Development.

There is limited understanding of how mechanical signals regulate tendon development. The nucleus has emerged as a major regulator of cellular mechanosensation via the linker of nucleoskeleton and cytoskeleton (LINC) protein complex. Specific roles of LINC in tenogenesis have not been explored.

Normothermic Machine Perfusion Improves Outcomes for Donation After Cardiac Death Allografts With Extended Donor Warm Ischemia Time.

Introduction: Donation after circulatory death (DCD) allografts are underutilized in liver transplantation (LT) due to increased risk of complications. These risks stem from ischemic injury sustained during the total donor warm ischemia time (tDWIT), historically limited to 30 min. Normothermic machine perfusion (NMP) can mitigate these risks and facilitate LT of DCD grafts with extended tDWIT.

Review: Placental physiology and fetal programming in ruminants under heat stress.

The placenta plays a crucial role in transferring nutrients and oxygen between the dam and fetus during pregnancy. It is highly influenced by environmental conditions, especially stressors such as heat and nutritional deficiencies, which can significantly impact the fetus's long-term health and development. Cattle, especially dairy cows, commonly experience stress during late gestation, which can lead to changes in behavior and physiology, affecting both subsequent milk production and fetal development.

Leveraging artificial intelligence for inclusive maternity care: Enhancing access for mothers with disabilities in Africa.

Women with disabilities face significant barriers in accessing maternal healthcare, which increases their risk of adverse pregnancy outcomes, particularly in Africa, where resources are limited. Artificial intelligence (AI) presents a unique opportunity to improve inclusivity and accessibility to antenatal care, skilled birth attendance and postnatal care for these women. This paper explores the potential of AI to address the socio-economic, physical, and institutional barriers that limit the utilisation of maternal healthcare services by women with disabilities.

The MUSIQ calculator was originally developed to help clinics identify contextual factors that may affect QI success. This retrospective study adapted the MUSIQ calculator to serve as an evaluative tool for practice facilitators engaged in a colorectal cancer screening initiative.

Mechanically Robust Mesoporous UiO-66-NH/Nanofibrous Aerogel for Organophosphonates Detoxification.

There is a critical need for novel composite materials for high-performance chemical filtration and detoxification of organophosphonates (OPs) and other harmful compounds found in nerve agents, pesticides, and industrial processes. In this work, rapid hydrolysis of OPs using high-surface-area zirconium-based MOF-aerogel composites is demonstrated. Using a unique surfactant-templated solvothermal synthesis method, mesoporous UiO-66-NH grown on the fibers within a polyacrylonitrile (PAN)/polyvinylpyrrolidone (PVP) nanofibrous sponge can produce a 3D MOF-polymer matrix with a specific surface area of up to 900 m g -almost 2X larger than the highest previously reported values while maintaining robust mechanical integrity.

Replicating PET Hydrolytic Activity by Positioning Active Sites with Smaller Synthetic Protein Scaffolds.

Evolutionary constraints significantly limit the diversity of naturally occurring enzymes, thereby reducing the sequence repertoire available for enzyme discovery and engineering. Recent breakthroughs in protein structure prediction and de novo design, powered by artificial intelligence, now enable to create enzymes with desired functions without solely relying on traditional genome mining. Here, a computational strategy is demonstrated for creating new-to-nature polyethylene terephthalate hydrolases (PET hydrolases) by leveraging the known catalytic mechanisms and implementing multiple deep learning algorithms and molecular computations.

Dimensions of the functional degrees of freedom of the first serve in tennis.

We examined the influence of court side and target location of the ball on the coordination and control of the tennis serve. Five male and five female experienced players performed 10 'first-serves' to centre and wide targets. 3D kinematics of the service were analysed from two frames of reference: joint position (v) and joint angle (ω) with emphasis on the qualitative aspects of movement coordination.

Excessive leaf oil modulates the plant abiotic stress response via reduced stomatal aperture in tobacco (Nicotiana tabacum).

High lipid producing (HLP) tobacco (Nicotiana tabacum) is a potential biofuel crop that produces an excess of 30% dry weight as lipid bodies in the form of triacylglycerol. While using HLP tobacco as a sustainable fuel source is promising, it has not yet been tested for its tolerance to warmer environments that are expected in the near future as a result of climate change. We found that HLP tobacco had reduced stomatal conductance, which results in increased leaf temperatures up to 1.

Strategies used by organisms to survive very cold climates - student's guide.

We briefly examine how cold-hardiness in general, including freeze-tolerance, freeze-avoidance and dehydration strategies allow survival in cold climates, through the eyes of some specific insects and fish. Strategies do vary with geography and latitude, even between two types of insects living in the same area. We look at ice nucleation proteins to enhance freezing and antifreeze proteins to help avoid ice formation or, in some cases, to hinder what is known as recrystallization, as a frozen organism thaws.

E-cigarette Use and Incident Cardiometabolic Conditions in the All of Us Research Program.

Introduction: Although several potential respiratory and cardiovascular health effects of e-cigarettes have been reported, their association with incident cardiometabolic conditions remains unclear.

Methods: We used longitudinal data from the All of Us research program to investigate the association between current exclusive e-cigarette use (EE), exclusive combustible cigarette use (ECC), and dual use (DU) with incident cardiometabolic conditions, including hypertension, type 2 diabetes mellitus (T2DM), chronic obstructive pulmonary disease (COPD), heart failure (HF), and atherosclerotic cardiovascular disease (ASCVD), using Cox regression analyses adjusted for age, sex, race and ethnicity, and body mass index (BMI). ECC use was used as a positive control to validate our methodology/findings.
