Assessment and Predictors of Metabolic Syndrome in Patients of Xanthelasma Palpebrarum: An Observational Study.

Introduction: Xanthelasma palpebrarum is considered to be a cutaneous marker for cardiovascular diseases, and there is a known association with hypertension, insulin resistance, diabetes mellitus, obesity, and stroke.

Objectives: Our aim was to study the association and identify the predictors of metabolic syndrome in patients with xanthelasma palpebrarum.

Methods: An observational study was conducted on 55 patients in which patients of both sexes ages 20-70 years without any other skin condition were included after written informed consent.

The Effect of After-Hours Resection on the Outcomes in Patients with High-Grade Gliomas.

Objective: The "weekend effect" is the finding that patients presenting for medical care outside of regular working hours tend to have worse outcomes. There is a paucity of literature in the neuro-oncology space exploring this effect. We investigated the extent of resection and complication rates in patients undergoing after-hours high-grade glioma resection.

Optic nerve sheath diameter correlates with both success and failure of hydrocephalus treatment in pediatric patients with pineal region lesions.

Background: Pineal region lesions in children are heterogenous pathologies often symptomatic due to occlusive hydrocephalus and thus elevated intracranial pressure (ICP). MRI-derived parameters to assess hydrocephalus are the optic nerve sheath diameter (ONSD) as a surrogate for ICP and the frontal occipital horn ratio (FOHR), representing ventricle volume. As elevated ICP may not always be associated with clinical signs, the adjunct of ONSD could help decision making in patients undergoing treatment.

Diffusional and Biochemical Limitations to Photosynthesis Under Water Deficit for Field-Grown Cotton.

Water deficit stress limits net photosynthetic rate (A), but the relative sensitivities of underlying processes such as thylakoid reactions, ATP production, carbon fixation reactions, and carbon loss processes to water deficit stress in field-grown upland cotton require further exploration. Therefore, the objective of the present study was to assess (1) the diffusional and biochemical mechanisms associated with water deficit-induced declines in A and (2) associations between water deficit-induced variation in oxidative stress and energy dissipation for field-grown cotton. Water deficit stress was imposed for three weeks during the peak bloom stage of cotton development, causing significant reductions in leaf water potential and A.

Synthesis of -Tosyl Allylic Amines from Substituted Alkenes via Vanadoxaziridine Catalysis.

Herein, we report the catalytic allylic amination of α-methylalkenes with VODipic(HMPA) and chloramine T as the quantitative source of . The reaction works with high yields and stereoselectivities for α-methylalkenes. A proposed tosylnitrene-free catalytic cycle involving the formation of vanadoxaziridine complex as the active catalyst and aminovanadation across the substrate as the rate-determining step has been proposed.
