In-device Battery Failure Analysis.

Lithium-ion batteries are indispensable power sources for a wide range of modern electronic devices. However, battery lifespan remains a critical limitation, directly affecting the sustainability and user experience. Conventional battery failure analysis in controlled lab settings may not capture the complex interactions and environmental factors encountered in real-world, in-device operating conditions.

Opportunities to encourage adoption of a biomarker-enabled care pathway for Alzheimer's in primary care.

Unlabelled: Identification of early-stage Alzheimer's disease (AD) remains a challenge due to limited specialist availability, diagnostic access, disease awareness, and cultural factors. Blood-based biomarkers (BBBM) could play a critical role in the identification and referral of patients suspected of AD to specialty care. A multidisciplinary AD Biomarker Task Force was convened to evaluate current biomarker use cases, define an optimal biomarker-enabled AD diagnostic care pathway, and understand factors impacting adoption.

Familial chylomicronemia syndrome and treatments to target hepatic APOC3 mRNA.

Familial chylomicronemia syndrome (FCS) is a rare, recessive monogenic disorder characterized by severely elevated plasma triglyceride (TG) levels due to absent or markedly impaired lipoprotein lipase activity, leading to a greatly increased risk of acute pancreatitis. Naturally occurring very low levels of apoC-III are associated with low TG levels; thus, apoC-III is a target for TG lowering, and therapies have been developed to reduce apoC-III. Strategies to inhibit hepatic apoC-III synthesis include antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs).

Nature-focused livestreams: Connecting people to nature and to each other.

Engaging with nature has been found to have a range of benefits across the biopsychosocial and spiritual domains of well-being. Nature-focused livestreams (NFLs) offer an alternative to physically engaging with nature and serve as a window to nature as society has become more urbanized and has increasingly moved indoors. In this brief review, we examine the role of NFLs in connecting people with nature and connecting people with each other.

MicroRNAs in lung cancer: their role in tumor progression, biomarkers, diagnostic, prognostic, and therapeutic relevance.

MicroRNAs (miRNAs) are a class of small non-coding RNAs which are associated with post-transcriptional regulation of gene expression. Dysfunction or aberrant expression of miRNAs is predominant in various malignancies including lung cancer. Lung cancer is one of the commonest causes of cancer-related death worldwide, with a five-year survival of only 10-20%.

The Transcriptional Landscape of Adaptive Thermal Plasticity Within and Across Generations: The Role of Gene Expression and Alternative Splicing.

There is increasing evidence for the co-occurrence of adaptive within-generation (WGP) and transgenerational (TGP) plasticity and the ecological scenarios driving both types of plasticity. However, some aspects of their transcriptional mechanisms, such as the role of alternative splicing and the consequences of parental acclimation across life stages, have remained elusive. We explore these fundamental questions by considering the desert endemic Drosophila mojavensis for which prior evidence indicates adaptive thermal acclimation within and across generations.

Variation in wood density across South American tropical forests.

Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates and carbon maps. The need to understand how and why wood density varies is especially critical in tropical America where forests have exceptional species diversity and spatial turnover in composition. As tree identity and forest composition are challenging to estimate remotely, ground surveys are essential to know the wood density of trees, whether measured directly or inferred from their identity.

Clinical Characteristics and Outcomes of Cardiac Findings in Young Persons Following SARS-CoV-2 Infection.
