Ischemia-reperfusion injury (IRI) is a major obstacle in liver transplantation, especially with steatotic donor livers. Dysbiosis of the gut microbiota has been implicated in modulating IRI, and plays a pivotal role in regulating host inflammatory and immune responses, but its specific role in liver transplantation IRI remains unclear. This study explores whether can mitigate IRI and its underlying mechanisms.

Abolition of Aorticorenal Ganglia Pacing Responses Improves Denervation Efficacy.

Hypertension

January 2025

Cardiology Department (P.B., X.L., V.T.T., M.A.B., A.V., E.Y., D.M.N., U.P., J.L., S.P.T., P.C.Q.), Westmead Hospital, Sydney, Australia.

Background: Transcatheter renal denervation (RDN) remains inconsistent despite developments in ablation technologies, due to the lack of an intraprocedural physiological end point.

Objective: To identify whether aorticorenal ganglion (ARG) guided RDN using microwave (MW) catheter leads to more consistent denervation outcomes compared with empirical MW ablation.

Methods: Pigs underwent sham procedure (n=8) or bilateral RDN using an in-house built open-irrigated MW catheter.

Rapid and accurate methods for tracing and identifying the origin of lamb are crucial for ensuring food authenticity and quality. This study developed a precise traceability method to determine the origin of lamb by integrating rapid evaporative ionization mass spectrometry (REIMS) with multivariate statistical analysis. Lamb samples from Xilin Gol, Ordos, and Hulun Buir ranches were identified by REIMS fingerprinting within 1 min.

Growing evidence indicates that type 2 diabetes (T2D) is associated with an increased risk of developing Parkinson's disease (PD) through shared disease mechanisms. Studies show that insulin resistance, which is the driving pathophysiological mechanism of T2D plays a major role in neurodegeneration by impairing neuronal functionality, metabolism and survival. To investigate insulin resistance caused pathological changes in the human midbrain, which could predispose a healthy midbrain to PD development, we exposed iPSC-derived human midbrain organoids from healthy individuals to either high insulin concentration, promoting insulin resistance, or to more physiological insulin concentration restoring insulin signalling function.

Mural cells are essential for maintaining the proper functions of microvasculatures. However, a key challenge of microvascular tissue engineering is identifying a cellular source for mural cells. We showed that , circulating fibrocytes (CFs) can (1) shear and stabilize the microvasculatures formed by vascular endothelial cells (VECs) in a collagen gel, (2) form gap junctions with VECs and (3) induce basement membrane formation.

Arthroscopic ligament repair has gained popularity as a minimally invasive alternative for addressing ankle instability, due to its minimally invasive nature, which offers significant advantages over traditional open procedures. These benefits include smaller incisions, reduced soft tissue dissection, and the ability to concurrently manage intra-articular pathology, contributing to its popularity among surgeons and patients alike. Despite these advantages, the procedure presents a range of technical challenges and potential complications that can impact patient outcomes.

Intrahepatic cholangiocarcinoma (iCCA) is a highly malignant tumor of the liver and gallbladder, which is usually diagnosed at an advanced stage and the opportunity for surgery is lost. Therefore, conversion therapy is important to convert the iCCA into a resectable state. In recent years, the conversion protocol of immuno-chemotherapy has been applied for advanced liver cancer.

As plastic surgeons, we strive to achieve the best possible outcomes for our patients. However, despite being a good surgeon with a sound plan that was thoughtfully crafted and well executed, complications still happen. As a result, surgeons involved in the care of patients who have complications can experience mental and emotional suffering, including feelings of guilt, sadness, anxiety, and stress.

Our literature review describes the complicated intersection of the physician/surgeon's professional practice and their spouse/domestic partner, acknowledging that the existing literature specific to plastic surgeons is limited. Nevertheless, the broader research of physicians and other surgical fields identifies many risk factors for work-home conflicts, which can negatively impact the surgeon and the spouse. Furthermore, certain studied groups have other unique challenges and considerations, such as women surgeons, residents, and dual-physician couples.

The benefits of exercise for the general population are well established, although there is limited information focusing on its importance for plastic surgeons. Plastic surgery is arguably one of the most physically taxing fields within medicine due to lengthy operations that often require putting oneself in uncomfortable positions for the majority of the case, all while maintaining mental focus and discipline. It is essential to incorporate regular routines that can optimize a plastic surgeon's mental and physical capacity both short- and long-term.
