Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia.

The mechanisms that drive placental dysfunction in pregnancies complicated by hypoxia and fetal growth restriction remain poorly understood. Changes to mitochondrial respiration contribute to cellular dysfunction in conditions of hypoxia and have been implicated in the pathoaetiology of pregnancy complications, such as pre-eclampsia. We used bespoke isobaric hypoxic chambers and a combination of functional, molecular and imaging techniques to study cellular metabolism and mitochondrial dynamics in sheep undergoing hypoxic pregnancy.

Interspecies interactions mediated by arginine metabolism enhance the stress tolerance of against .

Colorectal cancer (CRC) is a common cancer accompanied by microbiome dysbiosis. Exploration of probiotics against oncogenic microorganisms is promising for CRC treatment. Here, differential microorganisms between CRC and healthy control were analyzed.

Ultrasound-guided radiofrequency ablation for isthmus papillary thyroid microcarcinoma: a prospective 2 years of follow-up study.

To explore the safety and clinical efficacy of radiofrequency ablation (RFA) for papillary thyroid microcarcinoma (PTMC) located in the isthmus. This prospective study enrolled patients with single isthmus PTMC admitted to General Surgery Department of 983rd Hospital of Joint Logistic Support Force of PLA from 2017 to 2022. After ablation, the ultrasound and contrast-enhanced ultrasound (CEUS) were performed to follow up the outcomes at 1, 3, 6, 12, 18, and 24 months.

Loss of flavonoids homeostasis leads to pistillody in sua-CMS of Nicotiana tabacum.

The homeotic transformation of stamens into pistil-like structures (pistillody) causes cytoplasmic male sterility (CMS). This phenomenon is widely present in plants, and might be induced by intracellular communication (mitochondrial retrograde signaling), but its systemic regulating mechanism is still unclear. In this study, morphological observation showed that the stamens transformed into pistil-like structures, leading to flat and dehiscent pistils, and fruit set decrease in sua-CMS (MS K326, somatic fusion between Nicotiana.

Influences of age and sex on the diagnostic accuracy of human epididymis secretory protein 4 for malignant pleural effusion.

Previous studies have suggested that the presence of human epididymal protein 4 (HE4) in pleural fluid can be used to diagnose malignant pleural effusion (MPE) with moderate accuracy. However, the factors that affect the diagnostic accuracy of HE4 remain unknown. This study aimed to examine how age and sex influence the diagnostic accuracy of HE4.
