Sex-Specific Metabolic Effects of Gestational Chronodisruption and Maternal Melatonin Supplementation in Rat Offspring.

Gestational chronodisruption, increasingly common due to irregular light exposure, disrupts maternal-fetal circadian signaling, leading to long-term health issues in offspring. We utilized a chronic photoperiod shifting model (CPS) in pregnant rats to induce chronodisruption and investigated the potential mitigating effects of maternal melatonin supplementation (CPS + Mel). Male and female offspring were evaluated at 3 ages (90, 200, and 400 days of age) for metabolic profiles, hormonal responses, cytokine levels, and adipose tissue activity.

Unlabelled: Extubation failure (EF) after cardiac surgery is associated with poorer outcomes. Approximately 50% of children with Down syndrome (DS) have congenital heart disease. Our primary aim was to describe the frequency of EF and identify risk factors for its occurrence in a population of patients with DS after cardiac surgery.

Feeding Ecology of the Cuvier's Gazelle (, Ogilby, 1841) in the Sahara Desert.

Knowledge of the feeding ecology of ungulates in arid biomes offers an interesting model for understanding the drought resistance of large desert-adapted herbivores, a crucial issue in the face of increasing desertification due to climate change. To assess the feeding ecology of the endangered Cuvier's gazelle () in the Sahara desert, we used a multi-method approach combining faecal samples, direct observations, and the recording of indirect signs of feeding. We hypothesised that browser behaviour is the best foraging strategy for species living in hyper-arid environments, mainly due to long periods without grazing opportunities.

Liquid biopsy to detect resistance mutations against anti-epidermal growth factor receptor therapy in metastatic colorectal cancer.

Colorectal cancer (CRC) is a major cause of mortality worldwide, associated with a steadily growing prevalence. Notably, the identification of , , and mutations has markedly improved targeted CRC therapy by affording treatments directed against the epidermal growth factor receptor (EGFR) and other anti-angiogenic therapies. However, the survival benefit conferred by these therapies remains variable and difficult to predict, owing to the high level of molecular heterogeneity among patients with CRC.

Cinaciguat (BAY-582667) Modifies Cardiopulmonary and Systemic Circulation in Chronically Hypoxic and Pulmonary Hypertensive Neonatal Lambs in the Alto Andino.

Neonatal pulmonary hypertension (NPHT) is produced by sustained pulmonary vasoconstriction and increased vascular remodeling. Soluble guanylyl cyclase (sGC) participates in signaling pathways that induce vascular vasodilation and reduce vascular remodeling. However, when sGC is oxidized and/or loses its heme group, it does not respond to nitric oxide (NO), losing its vasodilating effects.

Induction of SARS-CoV-2 neutralizing antibodies by CoronaVac and BNT162b2 vaccines in naïve and previously infected individuals.

Background: A major challenge of the SARS-CoV-2 pandemic is to better define "protective thresholds" to guide the global response. We aimed to characterize the longitudinal dynamics of the antibody responses in naturally infected individuals in Chile and compared them to humoral responses induced after immunization with CoronaVac-based on an inactivated whole virus -or the BNT162b2- based on mRNA-vaccines. We also contrasted them with the respective effectiveness and efficacy data available for both vaccines.

Development of a validated method for rapid quantification of up to sixteen cannabinoids using ultra-high-performance liquid chromatography diode-array detector with optional electrospray ionization time-of-flight mass spectrometry detection.

Due to the recent legalization of medical and recreational Cannabis in many countries in the world, there has been an increasing demand for accurate quantification of a growing number of cannabinoids. To meet this challenge, a method for rapid quantification of up to sixteen cannabinoids using ultra-high-performance liquid chromatography diode-array detector (UHPLC-DAD) has been developed, validated and used in the analysis of hemp concentrates. While published LC-UV methods were usually for twelve or less cannabinoids and might not achieve baseline separation of some critical pairs of cannabinoids, e.
