Macrodactyly is a congenital disease characterized by aggressive overgrowth of adipose tissue in digits or limbs frequently accompanied with hyperostosis and nerve enlargement; its pathological mechanism is poorly understood. Adipose-derived stem cells (ASCs) have been extensively studied in tissue engineering and regenerative medicine as an ideal alternative substitute for bone marrow-derived mesenchymal stem cells (BM-MSCs), but their pathological role is largely unknown. In this study, ASCs from macrodactyly adipose tissues (Mac-ASCs) were isolated and compared to ASCs derived from the normal abdominal subcutaneous adipose tissue (Sat-ASCs) for cell morphology, surface marker expression, proliferation rate, and tri-lineage differentiation potential. Despite similar cell morphology and cell surface marker expression, Mac-ASCs showed higher cell proportion in the S phase and increased proliferation compared with Sat-ASCs. Moreover, osteogenic and chondrogenic differentiation capacities were enhanced in Mac-ASCs, with reduced adipogenic potential. In addition, the expression levels of adipogenic genes were lower in undifferentiated Mac-ASCs than in Sat-ASCs. These findings unraveled enhanced proliferation activity, a regression in the differentiation stage, and greater potentiality of ASCs in macrodactyly, which could contribute to hyperostosis and nerve enlargement in addition to adipose tissue overgrowth in patients.

Background: Obesity, characterized by excessive adipose tissue, is associated with chronic low-grade inflammation and elevated inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP). This inflammation is linked to obesity-associated medical problems, including cardiovascular diseases. One anastomosis gastric bypass (OAGB) has emerged as an effective metabolic and bariatric surgical procedure to address severe obesity and its associated inflammatory state.

Background: For many colorectal cancer patients, primary surgery is the standard care of treatment. Further insights in perioperative care are crucial. The aim of this study is to assess the prognostic value of body composition for postoperative complications after laparoscopic and open colorectal surgery.

Introduction: Metabolic syndrome (MetS) is a metabolic disorder related to obesity and insulin resistance and is the primary determinant of the development of low-intensity chronic inflammation. This continuous inflammatory response culminates in neuroimmune-endocrine dysregulation responsible for the metabolic abnormalities and morbidities observed in individuals with MetS. Events such as the accumulation of visceral adipose tissue, increased plasma concentrations of free fatty acids, tissue hypoxia, and sympathetic hyperactivity in individuals with MetS may contribute to the activation of the innate immune response, which compromises cerebral microcirculation and the neurovascular unit, leading to the onset or progression of neurodegenerative diseases.

Background: Obese subjects undergoing weight loss often fear the Yoyo dieting effect, which involves regaining or even surpassing their initial weight. To date, our understanding of such long-term obesity and weight cycling effects is still limited and often based on only short-term murine weight gain and loss studies. This study aimed to investigate the long-term impacts of weight cycling on glycemic control and metabolic health, focusing on adipose tissue, liver, and hypothalamus.

Background: This research aims to explore the anti-obesity potential of Wu-Mei-Wan (WMW), particularly its effects on adipose tissue regulation in obese mice induced by a high-fat diet (HFD). The study focuses on understanding the role of heat shock factor 1 (HSF1) in mediating these effects.
Methods: HFD-induced obese mice were treated with WMW.
