Dermatoglyphic finger patterns and pattern intensity were examined in a sample of 204 (105 males and 99 females) adults from the authochthonous Arab population of south central Morocco. No significant sex differences were found for the overall finger pattern incidence or for the pattern intensity index. A high incidence of arches is the most remarkable characteristic of this population as compared to other Mediterranean groups. The significant differences from two previous sets of Moroccan data indicate a remarkable heterogeneity within the present day Moroccan population. Also important is the differentiation of this sample from other north African ethnic groups such as Berbers and Tuaregs. An analysis of the dermatoglyphic relationships using R-matrix analysis, shows a relative proximity between this Moroccan series and other southwest European groups as compared to north African populations.

Deconvoluting thermomechanical effects in X-ray diffraction data using machine learning.
Acta Crystallogr A Found Adv
March 2025

X-ray diffraction is ideal for probing the sub-surface state during complex or rapid thermomechanical loading of crystalline materials. However, challenges arise as the size of diffraction volumes increases due to spatial broadening and because of the inability to deconvolute the effects of different lattice deformation mechanisms. Here, we present a novel approach that uses combinations of physics-based modeling and machine learning to deconvolve thermal and mechanical elastic strains for diffraction data analysis.

Background: Donor-derived cell-free DNA (dd-cfDNA) is a promising non-invasive biomarker for detecting graft injury in solid organ transplant recipients. Elevated dd-cfDNA levels are strongly associated with rejection and graft injury, especially antibody-mediated rejection (ABMR). While donor-specific antibodies (dnDSA) are crucial in ABMR, the relationship between dd-cfDNA levels and dnDSA features, such as DSA category, MFI and HLA target loci, remains unclear.

Background: Physical activities are widely implemented for non-pharmacological intervention to alleviate depressive symptoms. However, there is little evidence supporting their genotype-specific effectiveness in reducing the risk of self-harm in patients with depression.
Aims: To assess the associations between physical activity and self-harm behaviour and determine the recommended level of physical activity across the genotypes.
The effects of aerobic exercise on goal-directed attention and inhibitory control in individuals with high trait anxiety: an EEG study.
BMC Psychol
January 2025
Faculty of Psychology, Naval Medical University, Shanghai, China.
Anxiety is known to significantly impair cognitive function, particularly attentional control. While exercise has been demonstrated to alleviate these cognitive deficits, the precise neural mechanisms underlying these effects remain poorly understood. This study examines the effects of exercise on attentional control in individuals with high trait anxiety, based on attentional control theory, which suggests that such individuals have reduced top-down attention.
