Chronic stress produces long-term metabolic changes throughout the superfamily of nuclear receptors, potentially causing various pathologies. Sex hormones modulate the stress response and generate a sex-specific age-dependent metabolic imprint, especially distinct in the reproductive senescence of females. We monitored chronic stress recovery in two age groups of female Sprague Dawley rats to determine whether stress and/or aging structurally changed the glycolipid microenvironment, a milieu playing an important role in cognitive functions. Old females experienced memory impairment even at basal conditions, which was additionally amplified by stress. On the other hand, the memory of young females was not disrupted. Stress recovery was followed by a microglial decrease and an increase in astrocyte count in the hippocampal immune system. Since dysfunction of the brain immune system could contribute to disturbed synaptogenesis, we analyzed neuroplastin expression and the lipid environment. Neuroplastin microenvironments were explored by analyzing immunofluorescent stainings using a newly developed Python script method. Stress reorganized glycolipid microenvironment in the Cornu Ammonis 1 (CA1) and dentate gyrus (DG) hippocampal regions of old females but in a very different fashion, thus affecting neuroplasticity. The postulation of four possible neuroplastin environments pointed to the GD1a ganglioside enrichment during reproductive senescence of stressed females, as well as its high dispersion in both regions and to GD1a and GM1 loss in the CA1 region. A specific lipid environment might influence neuroplastin functionality and underlie synaptic dysfunction triggered by a combination of aging and chronic stress.The skeletal presence of 1,3-azoles in a variety of bioactive natural products, pharmacophores, and organic materials demands the derivatization of such heteroarenes regioselectively. Plenty of cross-coupling as well as cyclocondensation reactions have been performed to build up these skeletons but remained commercially unrealizable. A couple of severe drawbacks are faced by these traditional protocols that require a more straightforward strategy to obviate them. Transition metal-catalyzed C-H functionalization has emerged as a superior alternative in that context. 1,3-Azoles and their benzo counterparts have been extensively functionalized exploiting both noble and earth-abundant transition metals. Lately, C-2 functionalization have gained much traction due to the ease of attaining high regioselectivity and installation of synthetically manipulative functionalities. This critical review presents a bird's eye view of all major C-2 functionalization of (benz)azoles catalyzed by a diverse set of metals performed over the past 15 years. This study aimed to determine whether there is an association between clinical practices carried out during spontaneous vaginal birth (SVB), or clinical situations that arise during vaginal birth, and the incidence of post-traumatic stress disorder (PTSD). A cross-sectional study with 839 puerperal women in Spain was conducted. The Perinatal Post-traumatic Stress Disorder Questionnaire (PPQ) was administered online. The relationship between the risk of postpartum PTSD and various intrapartum complications was studied in addition to practices or procedures performed during the intrapartum period. PTSD (PPQ scores ≥19) was identified in 8.1% (68) of the women who participated. Among the risk factors for PTSD was a concerning intrapartum FHR tracing (adjusted OR 2.24, 95% CI 1.07-4.66). Other intrapartum practices also put women at risk of PTSD, including the administration of an enema (aOR 7.01, 95% CI 2.14-23.01), being required to stay lying down throughout the labor and birth (aOR 5.75, 95% CI 3.25-10. Spain. Care practitioners need to better appreciate their roles in preventing PTSD.Two di- and tetranuclear Ru(bda) (bda 2,2'-bipyridine-6,6'-dicarboxylate) mac
