Phenotypic analysis of complex bioengineered 3D models.

With advances in underlying technologies such as complex multicellular systems, synthetic materials, and bioengineering techniques, we can now generate in vitro miniaturized human tissues that recapitulate the organotypic features of normal or diseased tissues. Importantly, these 3D culture models have increasingly provided experimental access to diverse and complex tissues architectures and their morphogenic assembly in vitro. This review presents an analytical toolbox for biological researchers using 3D modeling technologies through which they can find a collation of currently available methods to phenotypically assess their 3D models in their normal state as well as their response to therapeutic or pathological agents.

Challenges and perspectives with understanding the concept of mental fatigue.

Mental fatigue is referred to as a psychophysiological or neurobiological state caused by prolonged periods of demanding cognitive activity. Sports and exercise science research have investigated the effects of experimentally induced mental fatigue on cognitive performance, with mixed results. It has been suggested that negative effects of mental fatigue on cognition performance in laboratory studies could translate to impaired sport performance.

Unlocking Therapeutic Potential: Mesenchymal Stem Cells-derived Exosomes in IUA Treatment, Current Status and Perspectives.

Intrauterine adhesion (IUA) is a condition caused by damage to the basal uterine layer which can lead to partial or full occlusion of the uterine cavity. Although traditional treatment options have been useful in mild and moderate cases, they have been unsatisfactory in severe IUA cases. Therefore, it is essential to improve the treatment strategies of IUA.

Single Precursor-Derived Sub-1 nm MoCo Bimetallic Particles Decorated on Phosphide-Carbon Nitride Framework for Sustainable Hydrogen Generation.

The strategic design and fabrication of efficient electrocatalysts are pivotal for advancing the field of electrochemical water splitting (EWS). To enhance EWS performance, integrating non-noble transition metal catalysts through a cooperative double metal incorporation strategy is important and offers a compelling alternative to conventional precious metal-based materials. This study introduces a novel, straightforward, single-step process for fabricating a bimetallic MoCo catalyst integrated within a three-dimensional (3D) nanoporous network of N, P-doped carbon nitride derived from a self-contained precursor.

Mechanical Cell Interactions on Curved Interfaces.

We propose a simple mathematical model to describe the mechanical relaxation of cells within a curved epithelial tissue layer represented by an arbitrary curve in two-dimensional space. This model generalises previous one-dimensional models of flat epithelia to investigate the influence of curvature for mechanical relaxation. We represent the mechanics of a cell body either by straight springs, or by curved springs that follow the curve's shape.

Background: Coeliac Disease (CD) affects up to 1.4% of children worldwide, with a rising global incidence. A less typical clinical presentation and the need for a life-long gluten exclusion diet raise challenges for diagnosis, management, and healthcare delivery with considerable impacts for CD patients and families as well as clinical services.

Feasibility and psychometric quality of smartphone administered cognitive ecological momentary assessments in women with metastatic breast cancer.

Objective: Metastatic breast cancer (MBC) is associated with burdensome side effects, including cognitive changes that require ongoing monitoring. Cognitive ecological momentary assessments (EMAs) allow for assessment of individual cognitive functioning in natural environments and can be administered via smartphones. Accordingly, we sought to establish the feasibility, reliability, and validity of a commercially available cognitive EMA platform.

The Application of Hydrogels in the Treatment of Intrauterine Adhesions.

Intrauterine Adhesions (IUA) are a significant cause of infertility and miscarriage, often resulting from trauma to the endometrium. While hysteroscopic adhesiolysis is the primary treatment, the use of hydrogels as anti-adhesion barriers and drug delivery systems is gaining traction for improving patient outcomes. This review aims to explore various hydrogel types, their role in tissue repair, and the integration of stem cell therapy.

Klebsiella pneumoniae species complex bloodstream infection in adult patients: changing epidemiology and determinants of poor outcomes.

Purpose: Klebsiella pneumoniae is a common cause of hospital- and community-acquired infection and can readily acquire multiple antimicrobial resistance determinants leading to poor health outcomes. We define the contemporary burden of disease, risk factors for antimicrobial resistance, and poor health outcomes for patients with K. pneumoniae bloodstream infection (Kp-BSI).

Isolation of a strain from an Eastern Gray Kangaroo.

Methanogenic archaea are a group of microorganisms found in the gastrointestinal tract of various herbivores and humans; however, the quantity (intensity) of methane emissions during feed digestion varies. Macropodids, such as the Eastern Gray Kangaroo (), are considered to be low methane-emitting animals, but their gut methanogenic archaea remain poorly characterized. Characterizing methanogens from animals with low methane emissions offers the potential to develop strategies and interventions that reduce methane emissions from livestock.

Targeted exonic sequencing identifies novel variants in a cerebral small vessel disease cohort.

Background And Aims: Cerebral small vessel diseases (CSVDs) are a set of conditions that affect the small blood vessels in the brain and can cause severe neurological pathologies such as stroke and vascular dementia. The most common monogenic CSVD is cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) which is caused by mutations in NOTCH3. However, only 15-20% of CADASIL cases referred for genetic testing have pathogenic mutations in NOTCH3.

Shifts in seasonal influenza patterns in Australia during and after COVID-19: A comprehensive analysis.

Background: During the COVID-19 pandemic, seasonal influenza virus circulation was heavily suppressed worldwide. In Australia, since the virus re-emerged in 2022, shifts in seasonal influenza patterns have been observed. Both the 2022 and 2023 seasons started earlier than pre-pandemic norms and were categorised as moderate to severe, highlighting the renewed importance of prevention strategies for seasonal influenza.

Estimating the differences in police and hospital records of people injured in traffic crashes in Dire Dawa City administration, Ethiopia.

The management of road safety relies on data from road traffic crashes to identify priorities, monitor trends and evaluate interventions. Both police and hospital records are important sources of information on crashes that result in injury; however, both are known to be incomplete, with the quality and completeness of data being lower in low- and middle-income countries. The aim of this study is to estimate the magnitude of the underreporting of crashes in Dire Dawa City, Ethiopia, as a case study that may be applicable elsewhere.

High-quality and diverse supportive care is required to improve outcomes and rehabilitation for people affected by breast cancer. However, the availability and access to high-quality supportive care services is limited due to factors including cost and demand.

International Symposium on Ruminant Physiology: Current perspective on rumen microbial ecology to improve fiber digestibility.

Although cellulose has received the most attention, further research is needed for a complete comprehension of other fiber components in forage and nonforage fiber sources corresponding with the array of enzymes needed for depolymerization and resulting fermentation of sugars. The carbohydrate-active enzymes (CAZymes) have been described in detail herein, although new information will no doubt accumulate in the future. Known CAZymes are attributed to taxa that are easily detected via 16S rRNA gene profiling techniques, but such approaches have limitations.
