: Prostate cancer (PC) and its treatment are often associated with side effects such as fatigue, muscle loss, and diminished quality of life (QoL). Physical exercise, particularly resistance training (RT) and aerobic training (AT), has been suggested as a strategy to mitigate these effects. However, the comparative efficacy of RT, AT, and combined RT/AT on QoL, body composition, physical fitness, and laboratory markers in PC patients is still insufficiently understood.

Objective: Progression of prediabetes to type 2 diabetes has been associated with β-cell dysfunction, whereas its remission to normoglycemia has been related to improvement of insulin sensitivity. To understand the mechanisms and identify potential biomarkers related to prediabetes trajectories, we compared the proteomics and metabolomics profile of people with prediabetes progressing to diabetes or reversing to normoglycemia within 1 year.

Research Design And Methods: The fasting plasma concentrations of 1,389 proteins and the fasting, 30-min, and 120-min post-oral glucose tolerance test (OGTT) plasma concentrations of 152 metabolites were measured in up to 134 individuals with new-onset diabetes, prediabetes, or normal glucose tolerance.

The case for neurons: a no-go theorem for consciousness on a chip.

Neurosci Conscious

December 2024

Department of Philosophy, Institute of Technology Futures, Karlsruhe Institute of Technology, Douglasstraße 24, Karlsruhe 76133, Germany.

We apply the methodology of no-go theorems as developed in physics to the question of artificial consciousness. The result is a no-go theorem which shows that under a general assumption, called dynamical relevance, Artificial Intelligence (AI) systems that run on contemporary computer chips cannot be conscious. Consciousness is dynamically relevant, simply put, if, according to a theory of consciousness, it is relevant for the temporal evolution of a system's states.

Gene regulation at the post-transcriptional level is prevalent in all domains of life. In bacteria, ProQ-like proteins have emerged as important RNA chaperones facilitating RNA stability and RNA duplex formation. In the major human pathogen Vibrio cholerae, post-transcriptional gene regulation is key for virulence, biofilm formation, and antibiotic resistance, yet the role of ProQ has not been studied.

Background: MECP2 Duplication Syndrome, also known as X-linked intellectual developmental disorder Lubs type (MRXSL; MIM: 300260), is a neurodevelopmental disorder caused by copy number gains spanning MECP2. Despite varying genomic rearrangement structures, including duplications and triplications, and a wide range of duplication sizes, no clear correlation exists between DNA rearrangement and clinical features. We had previously demonstrated that up to 38% of MRXSL families are characterized by complex genomic rearrangements (CGRs) of intermediate complexity (2 ≤ copy number variant breakpoints < 5), yet the impact of these genomic structures on regulation of gene expression and phenotypic manifestations have not been investigated.

Background: Approved tralokinumab maintenance dosing regimens for treatment of moderate-to-severe atopic dermatitis (AD) include 300 mg every two weeks (Q2W) and every four weeks (Q4W), that clinicians may consider for patients who achieved clear or almost clear skin at Week 16 with initial Q2W dosing.

Objectives: To identify predictive factors associated with maintained response after switching to tralokinumab Q4W, evaluate recapture of treatment response after relapse on Q4W, and assess treatment-emergent immunogenicity with tralokinumab Q4W.

Methods: These post hoc analyses utilized machine learning to identify predictive factors for maintained treatment response at Week 52 using data from the Week 16 responder population (ie, patients who met Investigator's Global Assessment of clear/almost clear skin [IGA 0/1] and/or ≥75% improvement in Eczema Area and Severity Index (EASI-75) at Week 16 with tralokinumab Q2W monotherapy) of the phase 3 ECZTRA 1 and 2 trials.

Despite the well-known effects of sexual selection on phenotypes, links between this evolutionary process and reproductive isolation, genomic divergence, and speciation have been difficult to establish. We unravel the genetic basis of sexually selected plumage traits to investigate their effects on reproductive isolation in barn swallows. The genetic architecture of sexual traits is characterized by 12 loci on two autosomes and the Z chromosome.

Optical Control of TRPM8 Channels with Photoswitchable Menthol.

Angew Chem Int Ed Engl

December 2024

Walther Straub Institute of Pharmacology and Toxicology, Ludwig Maximilian University of Munich, Goethestr. 33, 80336, Munich, Germany.

Transient receptor potential melastatin 8 (TRPM8) channels are well known as sensors for cold temperatures and cooling agents such as menthol and icilin and these channels are tightly regulated by the membrane lipid phosphoinositol-4,5-bisphosphate (PIP). Since TRPM8 channels emerged as promising drug targets for treating pain, itching, obesity, cancer, dry eye disease, and inflammation, we aimed at developing a high-precision TRPM8 channel activator, to achieve spatiotemporal control of TRPM8 activity with light. In this study, we designed, synthesized and characterized the first photoswitchable TRPM8 activator azo-menthol (AzoM).

As the field of neural organoids and assembloids rapidly expands, there is an emergent need for guidance and advice on designing, conducting and reporting experiments to increase the reproducibility and utility of these models. Here, our consortium- representing specialized laboratories from around the world- presents a framework for the experimental process that ranges from ensuring the quality and integrity of human pluripotent stem cells to characterizing and manipulating neural cells in vitro, and from transplantation techniques to considerations for modeling human development, evolution, and disease. As with all scientific endeavors, we advocate for rigorous experimental designs tailored to explicit scientific questions, and transparent methodologies and data sharing, to provide useful knowledge for both current research practices and for developing regulatory standards.

The archives of Ministry of Health of Russia, journal publications, interviews and memoirs testify that issue of quality of medications was key one in life of Russian Pharma in 1992-2004. The drug safety support considered not only as part of social policy, but also as rules that could be used to reformat"wild bazaar" into "controlled market". The media disputes, departmental justifications, political bills and memoirs give idea about "price of the issue" - tension of emotions, ambitions, financial losses.

Tau PET has attracted increasing interest as an imaging biomarker for 4-repeat (4R)-tauopathy progressive supranuclear palsy (PSP). However, the translation of in vitro 4R-tau binding to in vivo tau PET signals is still unclear. Therefore, we performed a translational study using a broad spectrum of advanced methodologies to investigate the sources of [F]PI-2620 tau PET signals in individuals with 4R-tauopathies, including a pilot PET autopsy study in patients.

Background: Metastatic prostate cancer remains a therapeutic challenge. Based on data of the STAMPEDE trial, patients with a low metastatic burden showed prolonged failure-free and overall survival when treated with prostate radio therapy (RT) in addition to standard of care (SOC). The objective of this study was to determine the cost-effectiveness of additional prostate RT compared to SOC alone for following subgroups: non-regional lymph node (NRLN) metastases, up to three bone metastases and four or more bone metastases.

The discovery of a new kind of experience can teach an agent what that kind of experience is like. Such a discovery can be epistemically transformative, teaching an agent something they could not have learned without having that kind of experience. However, learning something new does not always require new experience.

Physiology education in Africa faces challenges due to gaps in curricula across many of its universities, such as divergent content, a lack of standardized competencies, and suitable benchmarking. Here, we describe the development of the Physiology Curriculum for African Universities (PhysioCAFUN), a competency-based curriculum development guideline, as a first step to address such shortcomings. A committee of 15 physiologists from different African regions, Europe, and the United States was constituted to draft the PhysioCAFUN, which was introduced and revised during the joint East African Society of Physiological Sciences (EASPS) and African Association of Physiological Sciences (AAPS) conference held in Tanzania late 2023.
