Statins are effective in reducing cardiovascular disease (CVD) risk, but adherence rates remain low globally. Understanding and addressing modifiable influences on adherence is key to improving outcomes. Existing reviews have methodological limitations, often failing to integrate qualitative and quantitative data or consider specific barriers to statin adherence.

An African perspective to biodiversity conservation in the twenty-first century.

Philos Trans R Soc Lond B Biol Sci

January 2025

Georgina Mace Centre for the Living Planet, Imperial College London, Silwood Park Campus, Ascot SL5 7PY, UK.

Africa boasts high biodiversity while also being home to some of the largest and fastest-growing human populations. Although the current environmental footprint of Africa is low compared to other continents, the population of Africa is estimated at around 1.5 billion inhabitants, representing nearly 18% of the world's total population.

Background: Cutaneous melanoma (CM) is the leading cause of skin cancer mortality with associated high healthcare costs. Up-to-date reporting of epidemiological trends for CM is required to project future trends, assess the burden of disease and aid evaluation of new diagnostic, therapeutic and preventative strategies.

Objectives: To describe the trends in CM mortality, incidence, mortality-to-incidence indices (MIIs) and disability-adjusted life years (DALYs) over the last three decades.

Mollusca is the second most species-rich animal phylum, but the pathways of early molluscan evolution have long been controversial. Modern faunas retain only a fraction of the past forms in this hyperdiverse and long-lived group. Recent analyses have consistently recovered a fundamental split into two sister clades, Conchifera (including gastropods, bivalves and cephalopods) and Aculifera, comprising Polyplacophora ('chitons') and Aplacophora.

Form-function relationships often have tradeoffs: if a material is tough, it is often inflexible, and vice versa. This is particularly relevant for the elephant trunk, where the skin should be protective yet elastic. To investigate how this is achieved, we used classical histochemical staining and second harmonic generation microscopy to describe the morphology and composition of elephant trunk skin.

Antimicrobial resistance (AMR) is a major cause of death worldwide, with 1.27 M direct deaths from bacterial drug-resistant infections as of 2019. Dissemination of multidrug-resistant (MDR) bacteria in the environment, in conjunction with pharmapollution by active pharmaceutical ingredients (APIs), create and foster an environmental reservoir of AMR.

Structural brain organization in infancy is associated with later cognitive, behavioral, and educational outcomes. Due to practical limitations, such as technological advancements and data availability of fetal MRI, there is still much we do not know about the early emergence of topological organization. We combine the developing Human Connectome Project's large infant dataset with generative network modeling to simulate the emergence of network organization over early development.

Infertility affects one-in-six couples, often necessitating in vitro fertilization treatment (IVF). IVF generates complex data, which can challenge the utilization of the full richness of data during decision-making, leading to reliance on simple 'rules-of-thumb'. Machine learning techniques are well-suited to analyzing complex data to provide data-driven recommendations to improve decision-making.

Human DNA licensing initiates replication fork assembly and DNA replication. This reaction promotes the loading of the hMCM2-7 complex on DNA, which represents the core of the replicative helicase that unwinds DNA during S-phase. Here, we report the reconstitution of human DNA licensing using purified proteins.

Uncertainty remains regarding the role of diet in colorectal cancer development. We examined associations of 97 dietary factors with colorectal cancer risk in 542,778 Million Women Study participants (12,251 incident cases over 16.6 years), and conducted a targeted genetic analysis in the ColoRectal Transdisciplinary Study, Colon Cancer Family Registry, and Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO).

Physical unclonable functions (PUFs) are considered the most promising approach to address the global issue of counterfeiting. Current PUF devices are often based on a single stochastic process, which can be broken, especially since their practical encoding capacities can be significantly lower than the theoretical value. Here we present stochastic PUF devices with features across multiple length scales, which incorporate semiconducting polymer nanoparticles (SPNs) as fluorescent taggants.

Unsymmetric triazine-based triglucoside detergents for membrane protein stability.

Chembiochem

January 2025

Hanyang University, Department of Bionano Engineering, 55 Hanyangdaehak-ro, 15588, Ansan, KOREA, REPUBLIC OF.

Membrane proteins play a crucial role in a variety of biological processes and are key targets for pharmaceutical development. Structural studies of membrane proteins provide molecular insights into the mechanisms of these processes and are essential for effective drug discovery. Historically, these studies have relied on solubilization of the target protein using detergents, but conventional detergents often fail to maintain the stability of challenging membrane proteins.

Aims: Atrial fibrillation (AF) accounts for about 20% of all ischemic strokes worldwide. It is known that AF impairs health-related quality of life (HRQOL) in the general population, but data on HRQOL in stroke patients with newly diagnosed AF are sparse.

Methods: Post hoc analysis of the prospective, investigator-initiated, multicenter MonDAFIS study (NCT02204267) to analyze whether AF-related oral anticoagulation (OAC), and/or AF-symptom severity are associated with HRQOL after ischemic stroke or transient ischemic attack (TIA).

Background/aims: Buspirone shows promise in treating disorders of gut-brain interaction (DGBIs), particularly functional dyspepsia. However, findings have been mixed.

Methods: We systematically searched for prospective studies testing buspirone for any upper gastrointestinal DGBI in 4 databases (Cochrane, PubMed, Scopus, and PsycInfo).

Diuretic Potentiation Strategies in Acute Heart Failure.

JACC Heart Fail

January 2025

Department of Medicine, University of Mississippi Medical Center, Jackson, Mississippi, USA; Baylor Scott and White Research Institute, Baylor Scott and White Health, Dallas, Texas, USA. Electronic address:

Several trials have evaluated diuretic-based strategies to improve symptoms and outcomes in patients with acute heart failure (AHF). The authors sought to summarize the effect of different combination strategies on symptoms, physical signs, physiological variables, and outcomes in patients with AHF. Twelve trials were identified that assessed the addition of thiazide diuretics, sodium-glucose cotransporter 2 inhibitors, mineralocorticoid receptor antagonists, vasopressin receptor antagonists, carbonic anhydrase inhibitors, or loop diuretic intensification to conventional therapy for AHF.

CRISPR/Cas13X-assisted programmable and multiplexed translation regulation for controlled biosynthesis.

Nucleic Acids Res

January 2025

Key Laboratory of Carbohydrate Chemistry and Biotechnology, Ministry of Education, Jiangnan University, No. 1800, Lihu Avenue, Binhu District, Wuxi 214122, China.

Developing efficient gene regulation tools is essential for optimizing microbial cell factories, but most existing tools only modulate gene expression at the transcriptional level. Regulation at the translational level provides a faster dynamic response, whereas developing a programmable, efficient and multiplexed translational regulation tool remains a challenge. Here, we have developed CRISPRi and CRISPRa systems based on hfCas13X that can regulate gene translation in Bacillus subtilis.

Pulmonary arteriovenous malformations (PAVMs) cause cerebral abscess and ischemic stroke due to paradoxical emboli, risks that are increasingly recognized. We report the evolving placement of thoracic surgery in multi-disciplinary team management of PAVMs that were sporadic or associated with hereditary hemorrhagic telangiectasia. From 1983 to 2006, all patients receiving elective treatment had embolization.
