Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Age- and sex-related reference values for central blood pressure parameters in middle-aged and older Japanese adults: the Wakayama study.

Central blood pressure (BP) is more strongly associated with cardiovascular events than brachial BP. Few studies have described age-related changes in central BP in the general Japanese population. This study aimed to provide reference values for central BP parameters according to the age and sex, using data from 2964 participants aged 40-89 years (mean age: 60 years) who had no history of overt cardiovascular or chronic kidney disease and had not received antihypertensive, lipid-lowering, or hypoglycemic treatments.

Synthesis and characterization of nano iron oxide biochar composite for efficient removal of crystal violet from water.

In the present study, Coconut Husk Biochar (CHB) was synthesize from widely available, locally sourced agro waste, coconut husk and characterized using different techniques like scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) analysis, Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). CHB was tested for its ability to adsorb crystal violet (CV), a commonly used cationic dye, from water. It was capable of adsorbing more than 98 % of CV from water and follows Freundlich isotherm model with pseudo second order kinetics though the overall process was unfavourable.

Work-Family Care Obstacles and Life Satisfaction among Japanese Working Family Caregivers Living with an Older Care Recipient.

Introduction: The growing obstacles to balancing work and family caregiving responsibilities (work-family care obstacles) have led to heightened difficulties in work-life adjustment among employees, potentially resulting in decreased life satisfaction.

Objectives: The aims of this study were to investigate whether facing work-family care obstacles is associated with poor life satisfaction and whether it moderates the association between caregiver burden and life satisfaction among working family caregivers in Japan.

Methods: A cross-sectional descriptive study was conducted involving 141 family caregivers, all of whom were under 65 years old and living with older long-term care recipients.

Comparative analysis of meningeal transcriptomes in birds: Potential pathways of resilience to repeated impacts.

The meninges and associated vasculature (MAV) play a crucial role in maintaining cerebral integrity and homeostasis. Recent advances in transcriptomic analysis have illuminated the significance of the MAV in understanding the complex physiological interactions at the interface between the skull and the brain after exposure to mechanical stress. To investigate how physiological responses may confer resilience against repetitive mechanical stress, we performed the first transcriptomic analysis of avian MAV tissues using the Downy Woodpecker (Dryobates pubescens) and Tufted Titmouse (Baeolophus bicolor) as the comparison species.

Diverse somatic Transformer and sex chromosome karyotype pathways regulate gene expression in Drosophila gonad development.

The somatic sex determination gene () is required for the highly sexually dimorphic development of most somatic cells, including those of the gonads. In addition, somatic is required for the germline development even though it is not required for sex determination within germ cells. Germ cell autonomous gene expression is also necessary for their sex determination.

Impact of automated pop-up alerts on simultaneous prescriptions of antimicrobial agents and metal cations.

Background: Antimicrobial agents (AMAs) are essential for treating infections. A part of AMAs chelate with metal cations (MCs), reducing their blood concentrations. That drug-drug interaction could lead to a reduction of therapeutic efficacy and the emergence of drug-resistant bacteria.

Association between physical activity and the N-terminal pro-brain natriuretic peptide in a middle-aged Japanese population: The interaction with alcohol consumption, 2005-2006.

Objective: Higher N-terminal pro-brain natriuretic peptide (NT-proBNP) levels are a strong risk factor for cardiovascular disease. The current study aimed to clarify the cross-sectional association of physical activity (PA) with NT-proBNP and to identify the interaction of PA with alcohol consumption or cigarette smoking in middle-aged individuals.

Methods: The study included 4613 individuals (1824 men and 2789 women) (November 2005-November 2006).

Biofilm inhibition of Staphylococcus aureus by silver nanoparticles derived from Hellenia speciosa rhizome extract.

Staphylococcus aureus is the most common cause of serious health conditions because of the formation of biofilm, which lowers antibiotic efficacy and enhances infection transmission and tenacious behavior. This bacteria is a major threat to the worldwide healthcare system. Silver nanoparticles have strong antibacterial characteristics and emerged as a possible alternative.

The haves and have-nots: Infants use wealth to guide social behavior and evaluation.

Biases favoring the wealthy are ubiquitous, and they support and bolster vast resource inequalities across individuals and groups; yet, when these biases are acquired remains unknown. In Experiments 1 through 5 (Total = 232), using multiple methods, we found that 14- to 18-month-old infants track individuals' wealth (Experiments 1-5), prefer and selectively help rich (vs. poor) individuals (Experiments 2 and 3), and negatively evaluate poor individuals (Experiments 4 and 5).

The Interaction of a Gemini Surfactant with a DNA Quadruplex.

DNA secondary structures are stabilized by mono- and divalent cations. To examine the stability of the DNA quadruplex formed from (TTAGGG), its interaction with a dicationic Gemini surfactant in standard phosphate buffer was investigated. The Gemini surfactant begins to form micelles in buffer at a (critical micelle concentration) of 1.

Critical review on plant-derived quorum sensing signaling inhibitors in pseudomonas aeruginosa.

Pseudomonas aeruginosa, a biofilm-forming organism with complex quorum mechanisms (Las, Rhl, PQS, and IQS), poses an imminent danger to the healthcare sector and renders current treatment options for chemotherapy ineffectual. The pathogen's diverse pathogenicity, antibiotic resistance, and biofilms make it difficult to eradicate it effectively. Quorum sensing, a complex system reliant on cell density, controls P.

An extinct north American porcupine with a South American tail.

New World porcupines (Erethizontinae) originated in South America and dispersed into North America as part of the Great American Biotic Interchange (GABI) 3-4 million years ago. Extant prehensile-tailed porcupines (Coendou) today live in tropical forests of Central and South America. In contrast, North American porcupines (Erethizon dorsatum) are thought to be ecologically adapted to higher-latitude temperate forests, with a larger body, shorter tail, and diet that includes bark.
