Runs of Homozygosity and Inferences in Wild Populations.

Mol Ecol

January 2025

Conservation Biology Division, Northwest Fisheries Science Center, National Marine Fisheries Service, National Oceanic and Atmospheric Administration, Seattle, Washington, USA.

Long homozygous chromosome segments are known as runs of homozygosity (ROH); these reflect patterns of identity by descent and can be used to measure individual inbreeding, map recessive traits, and reconstruct demographic histories. Here, we review some key considerations with ROH detection and the inferences pertaining to inbreeding and demographic analyses in wild populations.

The detection of skeletal remains using human remain detection dogs (HRD) is often reported anecdotally by handlers to be a challenge. Limited studies have been conducted to determine the volatile organic compounds (VOCs) emitted from bones, particularly when there is limited organic matter remaining. This study aimed to determine the VOCs emitted from dry, weathered bones and examine the detection performance of HRD dogs on these bones when used as training aids.

Modeling Hydrogen Markets: Energy System Model Development Status and Decarbonization Scenario Results.

Energy Clim Chang

December 2024

South China University of Technology, School of Future Technology, 777 Xingye Ave East, Panyu District, Guangzhou, Guangdong, 511442, China.

Hydrogen can be used as an energy carrier and chemical feedstock to reduce greenhouse gas emissions, especially in difficult-to-decarbonize markets such as medium- and heavy-duty vehicles, aviation and maritime, iron and steel, and the production of fuels and chemicals. Significant literature has been accumulated on engineering-based assessments of various hydrogen technologies, and real-world projects are validating technology performance at larger scales and for low-carbon supply chains. While energy system models continue to be updated to track this progress, many are currently limited in their representation of hydrogen, and as a group they tend to generate highly variable results under decarbonization constraints.

Article Synopsis
  • Wildfire regimes are altering, raising concerns for aquatic ecosystems and fish species, as predicting fish responses can be complex due to multiple wildfire impacts.
  • Whole-ecosystem approaches like food web modeling can help understand these interactions, showing how different wildfire severities affect aquatic life dynamics in streams.
  • Simulations reveal that wildfires can have varying effects on periphyton, invertebrates, and fish biomass, influenced by fire severity and environmental changes, indicating a need to consider context when assessing wildfire impacts on aquatic ecosystems.

Introduction: Corneal confocal microscopy (CCM) detects neurodegeneration in mild cognitive impairment (MCI) and dementia and identifies subjects with MCI who develop dementia. This study assessed whether abnormalities in corneal endothelial cell (CEC) morphology are related to corneal nerve morphology, brain volumetry, cerebral ischemia, and cognitive impairment in MCI and dementia.

Methods: Participants with no cognitive impairment (NCI), MCI, and dementia underwent CCM to quantify corneal endothelial cell density (CECD) and area (CECA), corneal nerve fiber morphology, magnetic resonance imaging (MRI) brain volumetry, and severity of brain ischemia.

The archaeal class is widely and abundantly distributed in anoxic habitats. Metagenomic studies have suggested that they are mixotrophic, capable of CO fixation and heterotrophic growth, and involved in acetogenesis and lignin degradation. We analyzed 35 metagenome-assembled genomes (MAGs), including the first complete circularized MAG (cMAG) of the Bathy-6 subgroup, from the metagenomes of three full-scale pulp and paper mill anaerobic digesters and three laboratory methanogenic enrichment cultures maintained on pre-treated poplar.

Advancement and Innovations in Drying of Biopharmaceuticals, Nutraceuticals, and Functional Foods.

Food Eng Rev

August 2024

Department of Biosystems Engineering, University of Manitoba, E2-376, EITC, 75A Chancellor's Circle, Winnipeg, MB, R3T 2N2 Canada.

Drying is a crucial unit operation within the functional foods and biopharmaceutical industries, acting as a fundamental preservation technique and a mechanism to maintain these products' bioactive components and nutritional values. The heat-sensitive bioactive components, which carry critical quality attributes, necessitate a meticulous selection of drying methods and conditions backed by robust research. In this review, we investigate challenges associated with drying these heat-sensitive materials and examine the impact of various drying methods.

The Relationship Between Quantitative Ischemia, Early Revascularization, and Major Adverse Cardiovascular Events: A Multicenter Study.

JACC Adv

January 2025

Department of Medicine (Division of Artificial Intelligence in Medicine), Biomedical Sciences, and Imaging, Cedars-Sinai Medical Center, Los Angeles, California, United States.

Background: Observational data have suggested that patients with moderate to severe ischemia benefit from revascularization. However, this was not confirmed in a large, randomized trial.

Objectives: Using a contemporary, multicenter registry, the authors evaluated differences in the association between quantitative ischemia, revascularization, and outcomes across important subgroups.

Background: Patients with systemic right ventricle (SRV), either d-transposition of the great arteries following an atrial switch procedure or congenitally corrected transposition of the great arteries, develop severe right ventricular dysfunction, prompting appropriate medical therapy. However, the efficacy of beta-blockers and angiotensin receptor blockers or angiotensin-converting enzyme inhibitors (ACEI) in SRV patients is unproven.

Objectives: The objective of this study was to determine the effects of ACEI/ARB and beta-blockers on outcomes in SRV patients after accounting for likely cofounders affecting their use.

Efficacy and safety of iclepertin (BI 425809) with adjunctive computerized cognitive training in patients with schizophrenia.

Schizophr Res Cogn

June 2025

Boehringer Ingelheim Pharmaceuticals, Inc., 900 Ridgebury Road, Ridgefield, CT 06877, USA.

Unlabelled: Despite significant patient burden, there are no approved pharmacotherapies to treat symptoms of cognitive impairment associated with schizophrenia (CIAS). This double-blind, placebo-controlled, parallel-group Phase II trial assessed the efficacy and safety of pharmacological augmentation of at-home computerized cognitive training (CCT) with iclepertin (BI 425809, a glycine transporter-1 inhibitor). Participants with schizophrenia (aged 18-50 years) on stable antipsychotic therapy, who were compliant with CCT during the run-in period, were enrolled.

This article argues for a pluralization of the "platform capitalism" framework, suggesting we should think instead in terms of "platform capitalisms." This pluralization opens the way to a better account of how platforms work in different geocultural contexts, with our focus being on China, India and Japan. The article first outlines several roles the state has taken on in mediating platform capitalisms.

Cyanobacteria in winter: Seasonal dynamics of harmful algal blooms and their driving factors in boreal lakes.

Heliyon

December 2024

Groupe de Recherche en Écologie de la MRC Abitibi (GREMA), Institut de Recherche sur les Forêts, Université du Québec en Abitibi-Témiscamingue, 341 Rue Principale N, Amos, QC, J9T 2L8, Canada.

Lake cyanobacteria can overgrow and form blooms, often releasing life-threatening toxins. Harmful algal blooms (HABs) are typically caused by excess nutrients and high temperatures, but recent observations of cyanobacteria beneath the ice in boreal lakes suggest that the dynamics are more complex. This study investigates the seasonal dynamics of HABs in boreal lakes and identifies their driving factors.
