Summary: This study aimed to explore the feasibility of ultrafiltration (UF) and polyethylene glycol (PEG) precipitation for macroprolactin screening, as well as the incidence and clinical characteristics of Chinese patients with macroprolactinemia. The results showed a high correlation between UF and PEG precipitation, with PEG precipitation having smaller variation and substantial diagnostic consistency with gel filtration chromatography (GFC). The incidence of macroprolactinemia in Chinese patients with hyperprolactinemia (HPRL) was found to be low in this study. We recommend using PEG precipitation screening only for patients clinically suspected of having macroprolactinemia.

Summary: By incorporating alginate-porous starch solution as the gel matrix and slow-gelling agents, a curcumin-loaded microemulsion gel with improved drug loading efficiency and capacity was successfully prepared. The denser structure that entrapped all microemulsion droplets was observed, and drug release followed a diffusion-controlled mechanism depending on the components and pH value.CUR-ME-G with a curcumin concentration of 0.20% exhibited the best biological activity, suggesting its potential application in smart drug delivery systems.

Summary: This study established a diagnostic model to predict early recurrence of hepatocellular carcinoma based on the GAR value, with tumor size, number, BCLC stage, microvascular invasion, and GAR value identified as independent risk factors. The predictive model performed well, accurately predicting 1, 3, and 5-year disease-free survival and demonstrating better clinical usability compared to the BCLC staging system.

Summary: In a case where a young male presented with persistently elevated TSH levels but clinically and biochemically demonstrated euthyroidism, it was found that the patient harbored macro-TSH, a rare condition where the complex binding of TSH to other plasma proteins leads to elevated plasma TSH levels while the biologically active fraction remains normal.

Summary: This study evaluates the feasibility of simultaneously measuring urinary gamma-glutamyltransferase (gamma GT) and lactate dehydrogenase (LDH) to distinguish fresh from previously frozen specimens in urine drug monitoring. The results demonstrate that this measurement method can reliably determine the enzyme activity of urinary gamma GT and LDH, and the measurement results can accurately predict the storage mode of urine samples.

Summary: Elevated levels of serum alanine and aspartate aminotransferase (ALT and AST) were associated with a U-shaped relationship with cancer mortality, while both the lowest and highest levels of these enzymes were linked to increased risk. Higher levels of alkaline phosphatase (ALP) were also associated with higher cancer mortality. Gamma-glutamyltransferase (GGT) levels did not show a consistent relationship with cancer mortality, but an increase after median was associated with higher mortality risk. Further exploration is needed to understand the mechanisms behind these relationships.

Summary: This study investigated the potential role of sympathetic renal denervation (RD) in limiting myocardial damage and remodeling immediately after acute myocardial infarction (AMI) in pigs. The results showed that RD performed after AMI led to smaller necrotic areas, improved myocardial salvage index, higher cardiac output, and lower LV end diastolic volume compared to the control group. RD also resulted in reduced sympathetic activation and better cardiac function, indicating its potential for improving outcomes following AMI.

Summary: The study found that the free sulfhydryl groups in the hinge region of monovalent antibody fragments (rIgG) play a crucial role in the orientation of antibodies on immunosensors. Both chemical reduction and orientation affect the signal enhancement, with rIgG generally showing greater signal enhancement capacity.

Summary: This study investigated screening practices on admission to hospital wards and the risk of developing infection from colonisation. It found that the burden of antimicrobial-resistant Gram-negative bacteria (AMR-GNB) colonisation and the risk of progression to infection vary significantly across regions, pathogens, and time in hospitals.

Summary: This study presents five cases of sudden death secondary to myocardial infarction (MI) closely related to COVID-19 vaccination. Pathological analysis and genetic testing revealed that the patients carried pro-thrombotic mutations, suggesting a possible link between COVID-19 vaccination, pro-thrombotic genotypes, and acute cardiovascular events that requires further investigation.

Summary: Antibody light chains are synthesized in excess by plasma cells and can be secreted into biological fluids in different forms. Structural differences between monomers and dimers may affect their biological functions and pathogenicity. A simple preparatory procedure allows for the purification of FLC monomers and dimers from urine samples of patients with plasma cell disorders.

Summary: Transthyretin (TTR) amyloid cardiomyopathy (ATTR-CM) is a cause of heart failure characterized by misfolded TTR monomers deposited as amyloid fibrils in the myocardium. Standard treatment with TTR-stabilizing ligands may not be effective in advanced disease. Amyloid seeding, a self-propagating process, may further accelerate amyloid aggregation. Inhibition of amyloidogenesis combined with anti-seeding peptides and alternative strategies, such as TTR silencers and immunological amyloid disruptors, show promising results.

Summary: Gamma-glutamyl transferase (GGT) plays a role in the progression of atherosclerosis by promoting the generation of reactive oxygen species. It can also induce tissue factor expression, independently of its enzymatic activity. In this study, it was found that GGT-induced tissue factor stimulation is mediated by binding to Toll-like receptor 4, which is expressed on monocytes and colocalizes with GGT activity in atherosclerotic plaques.
