Distribution of early-branching Cyanobacteriia and the potential habitats that gave rise to the earliest oxygenic phototrophs.

The evolution of oxygenic photosynthesis in the Cyanobacteria was one of the most transformative events in Earth history, eventually leading to the oxygenation of Earth's atmosphere. However, it is difficult to understand how the earliest Cyanobacteria functioned or evolved on early Earth in part because we do not understand their ecology, including the environments in which they lived. Here, we use a cutting-edge bioinformatics tool to survey nearly 500,000 metagenomes for relatives of the taxa that likely bookended the evolution of oxygenic photosynthesis to identify the modern environments in which these organisms live.

Discovery and Development of CFTR Modulators for the Treatment of Cystic Fibrosis.

Cystic fibrosis (CF) is a genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which regulates ion and fluid transport across epithelial cells. Mutations lead to complications, with life-limiting lung disease being the most severe manifestation. Traditional treatments focused on managing symptoms, but advances in understanding CF's molecular basis led to small-molecule CFTR modulators.

Deriving the Landauer Principle From the Quantum Shannon Entropy.

We derive an expression to determine the equilibrium probability distribution of a quantum state in contact with a noisy thermal environment that formally separates contributions from quantum and classical forms of probabilistic uncertainty. A statistical mechanical interpretation of this probability distribution enables us to derive an expression for the minimum free energy costs for arbitrary (reversible or irreversible) quantum state changes. Based on this derivation, we demonstrate that─in contrast to classical systems─the free energy required to erase or reset a qubit depends sensitively on both the fidelity of the target state and on the physical properties of the environment, such as the number of quantum bath states, due primarily to the entropic effects of system-bath entanglement.

Risk factors that predict for presence of clinically significant, noncalcified plaque in younger adults.

Objective: Coronary artery calcium (CAC) scoring may be a useful tool for assessing cardiovascular disease in young adults, particularly in those with risk factors such as hypertension, dyslipidemia, or smoking. In this study, we aimed to address the risk factors for developing noncalcified plaque in young adults by assessing total plaque burden.

Methods: A single-center retrospective cohort study was conducted among 1026 consecutive patients aged 18-45 years who underwent CAC scoring and coronary computed tomography (CT) angiograms for clinical indications.

Ultrafast Photoflash Synthesis of High-Entropy Oxide Nanoparticles.

High-entropy metal oxides (HEOs) have recently received growing attention for broad energy conversion and storage applications due to their tunable properties. HEOs typically involve the combination of multiple metal cations in a single oxide lattice, thus bringing distinctive structures, controllable elemental composition, and tunable functional properties. Many synthesis methods for HEOs have been reported, such as solid-state reactions and carbon thermal shock methods.

(pollen beetle) gastrointestinal disease experimentally reproduced in sheep.

Intoxication of sheep and cattle by recently occurred in Uruguay and Argentina in association with severe drought. Although the disease was experimentally reproduced in sheep in the 1970s, there is limited information on clinical and pathologic findings of sheep experimentally intoxicated by this beetle. Here, we described the clinical, gross, and microscopic findings in 3 sheep orally dosed with (treatment group, TG) and in 2 control sheep (control group, CG) dosed with distilled water.

Evolutionary insights into gut acidification: Invertebrate-like mechanisms in the basal vertebrate hagfish.

Acidification is a key component of digestion throughout metazoans. The gut digestive fluid of many invertebrates is acidified by the vesicular-type H+-ATPase (VHA). In contrast, vertebrates generate acidic gut fluids using the gastric H+/K+-ATPase (HKA); an evolutionary innovation linked with the appearance of a true stomach that greatly improves digestion, absorption, and immune function.

Long-term performance and durability of lime-stabilized oil-contaminated soils.

In oil-rich regions, the increasing risk of oil spills on soil is largely attributed to intensified extraction and transportation activities. This situation necessitates a focus on the short-term and long-term strength of contaminated soils. While existing literature primarily evaluates the oil-contaminated soils over short-term periods, typically up to 28 days, it is essential to investigate their long-term performance, extending the evaluation period to 365 days.

Treatment approaches in advanced penile cancer: targeted therapies and immunotherapy.

Penile cancer is a rare genitourinary malignancy which can be treated with surgery or radiation for localized disease, but often requires systemic treatment with chemotherapy for recurrent or metastatic disease. With the emergence of immune checkpoint inhibitors and targeted therapies for specific genomic aberrations in the treatment of over a dozen other cancers, recent studies have sought to identify therapies other than chemotherapy in treating this uncommon cancer. Several ongoing trials involving immune checkpoint inhibitors, tyrosine kinase inhibitors, and antibody drug conjugates are attempting to identify additional therapies.

Nutrition Users' Guides: RCTs Part 2 - structured guide for interpreting and applying study results from randomised controlled trials on therapy or prevention questions.

This article continues from a prior commentary on evaluating the risk of bias in randomised controlled trials addressing nutritional interventions. Having provided a synopsis of the risk of bias issues, we now address how to understand trial results, including the interpretation of best estimates of effect and the corresponding precision (eg, 95% CIs), as well as the applicability of the evidence to patients based on their unique circumstances (eg, patients' values and preferences when trading off potential desirable and undesirable health outcomes and indicators (eg, cholesterol), and the potential burden and cost of an intervention). Authors can express the estimates of effect for health outcomes and indicators in relative terms (relative risks, relative risk reductions, OR or HRs)-measures that are generally consistent across populations-and absolute terms (risk differences)-measures that are more intuitive to clinicians and patients.

Nutrition users' guides: RCTs part 1 - structured guide for assessing risk of bias in randomised controlled trials that address therapy or prevention questions.

The purpose of this article, part 1 of 2 on randomised controlled trials (RCTs), is to provide readers (eg, clinicians, patients, health service and policy decision-makers) of the nutrition literature structured guidance on interpreting RCTs. Evaluation of a given RCT involves several considerations, including the potential for risk of bias, the assessment of estimates of effect and their corresponding precision, and the applicability of the evidence to one's patient. Risk of bias refers to flaws in the design or conduct of a study that may lead to a deviation from measuring the underlying true effect of an intervention.

Predicting conversion to psychosis using machine learning: response to Cannon.

Background: We previously reported that machine learning could be used to predict conversion to psychosis in individuals at clinical high risk (CHR) for psychosis with up to 90% accuracy using the North American Prodrome Longitudinal Study-3 (NAPLS-3) dataset. A definitive test of our predictive model that was trained on the NAPLS-3 data, however, requires further support through implementation in an independent dataset. In this report we tested for model generalization using the previous iteration of NAPLS-3, the NAPLS-2, using the identical machine learning algorithms employed in our previous study.

Quick Oil Red O, Paint3D and Biopython as an economical tool to measure total lipid levels in .

Quick Oil Red O staining is a well established method to assay total lipid levels in , but the software to clean up and analyse the images is either laborious, expensive or both. We have developed a process that uses an existing protocol to stain the animals, followed by Magic Select in Paint3D to remove background and then a custom script in Biopython to quantify average pixel intensity animal. The software is free, accessible and relatively easy to use for undergraduate researchers.

Clinical Use of Dostarlimab in Advanced Stage and Recurrent Endometrial Cancer: Patient Selection and Perspectives.

Endometrial cancer (EC) is the most common gynecologic cancer in developed nations with reported 420,368 new cases worldwide in 2022 and resulting in 97,723 deaths that year; it is also one of the few cancers with expected increases in incidence and mortality, which are expected to increase by 50% and 70%, respectively, by 2045. The mortality from EC can largely be attributed to the advanced stage and recurrent cases. Over the past decade, the standard of care for treatment of primary advanced stage and recurrent EC has been chemotherapy, resulting in a median overall survival (OS) of less than 3 years.
