Association of hormone profile with various respiratory disorders in sulfur mustard-chemical veterans.

Backgrounds: Chronic respiratory complications such as asthma, bronchiolitis obliterans, and chronic bronchitis are prevalent among individuals exposed to sulfur mustard (SM). This study investigates the hormonal changes associated with SM-induced respiratory disorders.

Methods: A cross-sectional analysis was conducted involving 276 male participants exposed to SM during the Iraq-Iran war and 64 healthy controls.

Asymmetry of the Frontal Aslant Tract Depends on Handedness.

Background And Purpose: The human brain displays structural and functional disparities between its hemispheres, with such asymmetry extending to the frontal aslant tract. This plays a role in a variety of cognitive functions, including speech production, language processing, and executive functions. However, the factors influencing the laterality of the frontal aslant tract remain incompletely understood.

Investigating the effect of drought stress and methanol spraying on the influential genes in the Calvin cycle and photorespiration of rapeseed ().

Due to global warming and changes in precipitation patterns, many regions are prone to permanent drought. Rapeseed (Brassica napus ) is one of the main sources of edible oils worldwide, and its production and yield are affected by drought. In this study, gene expression alterations under drought stress are investigated with bioinformatics studies to examine evolutionary relations of conserved motifs structure and interactions among Calvin cycle and photorespiration pathways key genes in drought-tolerant (SLM046) and drought-sensitive (Hayola308) genotypes of rapeseed.

Impact of white matter hyperintensities on structural connectivity and cognition in cognitively intact ADNI participants.

We used indirect brain mapping with virtual lesion tractography to test the hypothesis that the extent of white matter tract disconnection due to white matter hyperintensities (WMH) is associated with corresponding tract-specific cognitive performance decrements. To estimate tract disconnection, WMH masks were extracted from FLAIR MRI data of 481 cognitively intact participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI) and used as regions of avoidance for fiber tracking in diffusion MRI data from 50 healthy young participants from the Human Connectome Project. Estimated tract disconnection in the right inferior fronto-occipital fasciculus, right frontal aslant tract, and right superior longitudinal fasciculus mediated the effects of WMH volume on executive function.
