Exercise as a Therapeutic Strategy for Obesity: Central and Peripheral Mechanisms.

Obesity is a complex, multifactorial condition involving excessive fat accumulation due to an imbalance between energy intake and expenditure, with its global prevalence steadily rising. This condition significantly increases the risk of chronic diseases, including sarcopenia, type 2 diabetes, and cardiovascular diseases, highlighting the need for effective interventions. Exercise has emerged as a potent non-pharmacological approach to combat obesity, targeting both central and peripheral mechanisms that regulate metabolism, energy expenditure, and neurological functions.

Dorsomedial hypothalamus-raphe pallidus-cardiac sympathetic pathway mediates electroacupuncture intervention of stress-induced tachycardia.

Electroacupuncture at Neiguan point (PC6) effectively ameliorates tachycardia. However, very little is known about the neural pathway mechanism underlying the effect of electroacupuncture at PC6 in stress-induced tachycardia. Here, we investigate whether there exists a dorsomedial hypothalamus (DMH)-raphe pallidus (RP)-heart pathway to mediate the effect of electroacupuncture at PC6.

Comprehensive multiscale analysis of lactate metabolic dynamics in vitro and in vivo using highly responsive biosensors.

As a key glycolytic metabolite, lactate has a central role in diverse physiological and pathological processes. However, comprehensive multiscale analysis of lactate metabolic dynamics in vitro and in vivo has remained an unsolved problem until now owing to the lack of a high-performance tool. We recently developed a series of genetically encoded fluorescent sensors for lactate, named FiLa, which illuminate lactate metabolism in cells, subcellular organelles, animals, and human serum and urine.

Impacts of glutamate, an exercise-responsive metabolite on insulin signaling.

Aims: Disruption of the insulin signaling pathway leads to insulin resistance (IR). IR is characterized by impaired glucose and lipid metabolism. Elevated levels of circulating glutamate are correlated with metabolic indicators and may potentially predict the onset of metabolic diseases.

Electroacupuncture intervention on stress-induced cardiac autonomic imbalance in rats involves corticotropin-releasing hormone system activity.

Autonomic imbalance is a core aspect of stress response that strongly correlates to cardiovascular diseases. Enhanced activity of the central corticotropin-releasing hormone (CRH) system may result in autonomic imbalance to cause cardiovascular responses in a stress state. Electroacupuncture at PC6 acupoints has been demonstrated to prevent and treat cardiovascular diseases.

Designing Intracellular Compartments for Efficient Engineered Microbial Cell Factories.

With the rapid development of synthetic biology, various kinds of microbial cell factories (MCFs) have been successfully constructed to produce high-value-added compounds. However, the complexity of metabolic regulation and pathway crosstalk always cause issues such as intermediate metabolite accumulation, byproduct generation, and metabolic burden in MCFs, resulting in low efficiencies and low yields of industrial biomanufacturing. Such issues could be solved by spatially rearranging the pathways using intracellular compartments.

Effect of initiative pulmonary bullectomy on the risk of post-operative pneumothorax in patients with esophageal carcinoma: a propensity score-matched analysis.

Background: Postoperative pneumothorax can lead to additional invasive intervention and extended hospitalization. The effect of initiative pulmonary bullectomy (IPB) during the esophagectomy on preventing postoperative pneumothorax remains controversial. This study evaluated the efficacy and safety of IPB in patients who underwent minimally invasive esophagectomy (MIE) for esophageal carcinoma complicated by ipsilateral pulmonary bullae.

Muscle PARP1 inhibition extends lifespan through AMPKα PARylation and activation in .

Poly(ADP-ribose) polymerase-1 (PARP1) has been reported to play an important role in longevity. Here, we showed that the knockdown of the PARP1 extended the lifespan of , with particular emphasis on the skeletal muscle. The muscle-specific mutant exhibited resistance to starvation and oxidative stress, as well as an increased ability to climb, with enhanced mitochondrial biogenesis and activity at an older age.

Exercise-induced microbial changes in preventing type 2 diabetes.

The metabolic benefits associated with long-term physical activity are well appreciated and growing evidence suggests that it involves the gut microbiota. Here we re-evaluated the link between exercise-induced microbial changes and those associated with prediabetes and diabetes. We found that the relative abundances of substantial amounts of diabetes-associated metagenomic species associated negatively with physical fitness in a Chinese athlete students cohort.

Hypoxia as a Double-Edged Sword to Combat Obesity and Comorbidities.

The global epidemic of obesity is tightly associated with numerous comorbidities, such as type II diabetes, cardiovascular diseases and the metabolic syndrome. Among the key features of obesity, some studies have suggested the abnormal expansion of adipose-tissue-induced local endogenous hypoxic, while other studies indicated endogenous hyperoxia as the opposite trend. Endogenous hypoxic aggravates dysfunction in adipose tissue and stimulates secretion of inflammatory molecules, which contribute to obesity.

Neoadjuvant immunotherapy combined with chemotherapy significantly improved patients' overall survival when compared with neoadjuvant chemotherapy in non-small cell lung cancer: A cohort study.

Background: Programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) inhibitors displayed considerable advantages in neoadjuvant therapy of non-small cell lung cancer (NSCLC), but the specific application of neoadjuvant immunotherapy has not been well determined, and the long-term prognostic data of neoadjuvant immunochemotherapy combined with surgical resection of NSCLC remains limited. In this study, we intended to assess the efficacy of the neoadjuvant therapy of the PD-1 inhibitor and long-term prognosis in patients with resectable NSCLC.

Methods: We retrospectively analyzed NSCLC surgical patients treated with neoadjuvant therapy in our hospital, and divided them into a neoadjuvant chemotherapy group and a neoadjuvant immunotherapy combined with chemotherapy group.

Plasma Metabolomics Reveals β-Glucan Improves Muscle Strength and Exercise Capacity in Athletes.

The present study aimed to assess the changes in muscle strength and plasma metabolites in athletes with β-glucan supplementation. A total of 29 athletes who met the inclusion criteria were recruited for this study (ChiCTR2200058091) and were randomly divided into a placebo group (n = 14) and β-glucan group (n = 15). During the trial, the experimental group received β-glucan supplementation (2 g/d β-glucan) for 4 weeks and the control group received an equal dose of placebo supplementation (0 g/d β-glucan), with both groups maintaining their regular diet and exercise habits during the trial.

The roles of PARK gene family in myopathy.

The causative gene family of Parkinson's disease, PARK, plays important roles in the regulation of skeletal myopathy and is also involved in multiple biological processes, such as the modification of motor neurons, the transmission of nerve signals at the nerve-muscle junction, the regulation of skeletal muscle energy metabolism and mitochondrial quality, and the expression of myogenesis factors. PARK gene family regulates skeletal muscle mass, functions through a multi-level regulatory system, and plays a key role in the occurrence and development of skeletal myopathy. In this review, we summarize the structural characteristics, functions, and research of the PARK gene family in skeletal myopathy, providing a theoretical foundation and future research direction for in-depth study of the molecular mechanism for skeletal myopathy and giving references to further study on the role of PARK family in the development, the pathology, clinical diagnosis, and treatment of skeletal myopathy.

Proteomics and Organoid Culture Reveal the Underlying Pathogenesis of Hashimoto's Thyroiditis.

Hashimoto's thyroiditis (HT) is an autoimmune disease, and its incidence continues to rise. Although scientists have studied this disease for many years and discovered the potential effects of various proteins in it, the specific pathogenesis is still not fully comprehended. To understand HT and translate this knowledge to clinical applications, we took the mass spectrometric analysis on thyroid tissue fine-needle puncture from HT patients and healthy people in an attempt to make a further understanding of the pathogenesis of HT.

Central 5-HTR2C in the Control of Metabolic Homeostasis.

The 5-hydroxytryptamine 2C receptor (5-HTR2C) is a class G protein-coupled receptor (GPCR) enriched in the hypothalamus and the brain stem, where it has been shown to regulate energy homeostasis, including feeding and glucose metabolism. Accordingly, 5-HTR2C has been the target of several anti-obesity drugs, though the associated side effects greatly curbed their clinical applications. Dissecting the specific neural circuits of 5-HTR2C-expressing neurons and the detailed molecular pathways of 5-HTR2C signaling in metabolic regulation will help to develop better therapeutic strategies towards metabolic disorders.
