[Determination of 26 perfluorinated and polyfluoroalkyl compounds in human serum by solid-phase extraction-high performance liquid chromatography-tandem mass spectrometry].

Perfluorinated and polyfluoroalkyl compounds （PFASs） represent a category of synthetic chemicals renowned for their environmental persistence. Owing to their hydrophobic， oleophobic， and high-temperature-resistant properties， PFASs are extensively utilized in industrial， agricultural， and civilian sectors， including applications in leather， textiles， flame-retardant materials， lubricants， and coatings， among others. PFASs can accumulate within the human body， exhibiting multi-organ toxicity.

Arginine Metabolic Disruption Impairs Hair Regeneration via ROS-Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia.

Androgenetic alopecia (AGA), a pervasive hair loss disorder, lacks effective therapies due to incomplete pathogenic understanding. Growing evidence suggests a connection between AGA and metabolic disorders. Leveraging unbiased serum metabolomics, a strikingly differentiated metabolic signature in AGA patients compared to healthy controls is identified, with arginine deficiency exhibiting the most pronounced reduction among all amino acids.

Effective Tumor Annotation for Automated Diagnosis of Liver Cancer.

In recent years, visual cancer information retrieval using Artificial Intelligence has been shown to be effective in diagnosis and treatment. Especially for a modern liver-cancer diagnosis system, the automated tumor annotation plays a crucial role. So-called tumor annotation refers to tagging the tumor in Biomedical images by computer vision technologies such as Deep Learning.

Beyond the Rex: an innovative meso-intrahepatic portal vein bypass for late-onset extrahepatic portal vein occlusion after living donor liver transplantation.

The Meso-Rex bypass (MRB) is recognized as an effective treatment for portal hypertension secondary to extrahepatic portal vein occlusion (EHPVO) both in the pediatric and adult population, within or outside the context of liver transplantation. It is the preferred surgical treatment in most centers because not only does it addresses the portal hypertension, but also restores physiologic portal hepatopetal flow. However, the Rex recess, the landmark for this technique, may not be safely accessible in some patients.

IL-17A/F double producing T cells, unstable Tregs and quiescent TRMs in clinically healed lesions are potential cellular candidates for recurrence of psoriasis.

Biological antibodies targeting key cytokines such as IL-17 and IL-23 have revolutionized psoriasis outcome. However, the recurrence remains an urgent challenge to be addressed. Currently, most of the descriptions of skin T-cell characteristics in psoriasis are derived from lesional and non-lesional skin, and their characteristics in resolved lesions (clinically healed lesions) remain vague.

Deep Learning-Based Surgical Treatment Recommendation and Nonsurgical Prognosis Status Classification for Scaphoid Fractures by Automated X-ray Image Recognition.

Biomedical information retrieval for diagnosis, treatment and prognosis has been studied for a long time. In particular, image recognition using deep learning has been shown to be very effective for cancers and diseases. In these fields, scaphoid fracture recognition is a hot topic because the appearance of scaphoid fractures is not easy to detect.

Integrated bioinformatics analysis and experimental validation identifies CPE as a potential biomarker and therapeutic target for skin aging.

Ageing is an inevitable biological process characterized by progressive decline in physiological functions. It is a complex natural phenomenon that will cause structural and functional decline. Despite substantial progress in understanding the mechanism of ageing, both predictive biomarkers and preventive therapies remain limited.

Combined Hounsfield units of hepatocellular carcinoma on computed tomography and PET as a noninvasive predictor of early recurrence after living donor liver transplantation: Time-to-recurrence survival analysis.

Background: Liver transplantation is an effective treatment for preventing hepatocellular carcinoma (HCC) recurrence. This retrospective study aimed to quantitatively evaluate the attenuation in Hounsfield units (HU) on contrast-enhanced computed tomography (CECT) as a prognostic factor for hepatocellular carcinoma (HCC) following liver transplantation as a treatment. Our goal is to optimize its predictive ability for early tumor recurrence and compare it with the other imaging modality-positron emission tomography (PET).

Downregulated SPESP1-driven fibroblast senescence decreases wound healing in aged mice.

Background: Human dermal fibroblasts (HDFs) are essential in the processes of skin ageing and wound healing. However, the underlying mechanism of HDFs in skin healing of the elderly has not been well defined. This study aims to elucidate the mechanisms of HDFs senescence and how senescent HDFs affect wound healing in aged skin.

Usefulness of Diffusion-Weighted Imaging in Evaluating Acute Cellular Rejection and Monitoring Treatment Response in Liver Transplant Recipients.

Acute cellular rejection (ACR) is a significant immune issue among recipients following liver transplantation. Although diffusion-weighted magnetic resonance imaging (DWI) is widely used for diagnosing liver disease, it has not yet been utilized for monitoring ACR in patients after liver transplantation. Therefore, the aim of this study was to evaluate the efficacy of DWI in monitoring treatment response among recipients with ACR.
