Study Design: This retrospective study included 920 consecutive elective patients undergoing liver resection from 2017 to 2023. Patient demographics, postoperative surgical outcomes, postoperative length of stay (LOS), and costs were compared between LLR and OLR before and after propensity score matching (PSM).

Long-term effects of underground mining on surface soil moisture and vegetation environment: evidence from the Xishan mining area.

This research aims to study the prolonged effects of underground mining on the ecological environment, particularly on surface soil moisture (SM) and fractional vegetation cover (FVC). Using 21 years of data (2000-2020) from the Xishan mining area, a novel quantitative relational model was developed to disentangle the effects of mining activities from those of climate, soil type, and topography. The findings reveal that climatic factors, such as precipitation and air temperature, have significant effects on SM and FVC, while soil type and topographic features are important factors affecting SM and FVC.

5-HT receptor activation produces rapid antidepressant-like effects in rodents.

Ketamine is noted for its rapid onset antidepressant response and effectiveness in patients with treatment resistant depression. While most research has focused on glutamatergic mechanisms, recent studies show that antidepressant-like effects in rodents are dependent upon the serotonergic (5-HT) system and suggest a potential contribution of the 5-HT receptor. In this study we utilized CP-94253 to examine whether 5-HT receptor agonism produces rapid and sustained antidepressant-like effects, focusing on rodent models and treatment approaches commonly used to demonstrate the differentiated response to ketamine.

Effect of yoga on balance, falls, and bone metabolism: a systematic review of randomized controlled trials in healthy individuals.

Unlabelled: This systematic review of 18 RCTs assessed the impact of yoga on balance, fall risk, fear of falling, bone mineral density (BMD), and bone turnover markers in healthy individuals. Yoga significantly improved balance but its effects on BMD were inconclusive. Standardised protocols and longer-term studies are needed.

A case of asymptomatic giant renal angiomyolipoma with extrusion of fat content with literature review.

Angiomyolipoma is a benign mesenchymal tumour of kidney that consists of adipose tissue, muscle cells and blood vessels. Renal angiomyolipomas represent almost one percent of all renal tumours. We reported a case of a 50-year-old woman complaining of mild abdominal discomfort with no other symptoms and no remarkable medical history.

Protein digestibility and techno-functional performance of milk-alternative prototypes based on combinations of lentil and cereal protein.

Lentil protein isolate was combined with proteins from oat, rice, brewer's spent grain (BSGP) and wheat to achieve plant-based milk alternatives (PBMA) with improved protein quality and functionality. Due to the complementary amino acid (AA) profile of pulse protein which is high in lysine, and cereal protein which is high in sulphur amino acids, their combination at an optimised ratio resulted in a protein blend with a significantly improved indispensable amino acid score (IAAS) compared to the single ingredients. All protein combinations with lentil except for wheat resulted in a full IAAS for adults.
