Hepatic Estrogen Receptor Alpha Overexpression Protects Against Hepatic Insulin Resistance and MASLD.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with cardiometabolic risk. Although studies have shown that estradiol positively contributes to energy metabolism via estrogen receptor alpha (ERα), its role specifically in the liver is not defined. Therefore, this study aimed to evaluate the effects of ERα overexpression, specifically in the liver in mice fed a high-fat diet (HFD).

Self-perception of stuttering: association with self-perception of hearing, fluency profile, and contextual aspects.

Purpose: This study investigated the association between self-perception of stuttering and self-perception of hearing, speech fluency profile, and contextual aspects in Brazilian adults who stutter.

Methods: Fifty-five adults who stutter (ages 18 to 58 years), speakers of Brazilian Portuguese speakers, participated in an observational study that included: (a) a clinical history survey to collect identification, sociodemographic, clinical, and assistance data; (b) the Brazil Economic Classification Criteria (CCEB); (c) a hearing self-perception questionnaire (Speech, Spatial and Qualities of Hearing Scale - SSQ, version 5.6); (d) self-perception of the impact of stuttering (Brazilian Portuguese version of the Overall Assessment of the Speaker's Experience of Stuttering - Adults - OASES-A); and (e) an assessment of speech fluency (Fluency Profile Assessment Protocol -- PAPF).

Soybean tolerance to waterlogging is achieved by detoxifying root lactate via lactate dehydrogenase in leaves and metabolizing malate and succinate.

Waterlogging is a significant stressor for crops, particularly in lowland regions where soil conditions exacerbate the problem. Waterlogged roots experience hypoxia, disrupting oxidative phosphorylation and triggering metabolic reorganization to sustain energy production. Here, we investigated the metabolic aspects that differentiate two soybean sister lines contrasting for waterlogging tolerance.

Comparing the Extent of Methionine Oxidation in the Prion and Native Conformations of PrP.

Scrapie is a prion disease of sheep and goats. Prions (PrP) replicate by inducing a natively expressed protein (PrP) to refold into the prion conformation. PrP and PrP contain a disproportionately large number of methionines.

Durvalumab as consolidation therapy in patients who received chemoradiotherapy for unresectable stage III NSCLC: Real-world data from an expanded access program in Brazil (LACOG 0120).

Objective: The PACIFIC trial established standard therapy for patients with unresectable stage III NSCLC who did not progress after platinum-based concurrent chemoradiation therapy. However, real-world data, particularly from Latin America, remain limited. The LACOG 0120 study aimed to evaluate the efficacy and safety of consolidation therapy with durvalumab in a real-world setting in Brazil.
