Objectives: Despite substantial evidence that visceral obesity is an epidemiological risk factor for hyperuricemia (HUA), studies on the connection between the Metabolic Score for Visceral Fat (METS-VF) and HUA remain insufficient. This research focused on METS-VF's potential role as a risk factor for HUA.
Methods: Notably, 8,659 participants from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were enrolled in this study.
Purpose: Inguinal hernia is a common feature of decompensated liver cirrhosis and a frequent cause of life-threatening complications. The traditional treatment of inguinal hernia in patients with liver cirrhosis includes non-operative management; however, emerging data suggest elective surgical repair as a preferable approach. Therefore, we aimed to assess the outcomes of inguinal hernia repair in patients with liver cirrhosis and describe their clinical characteristics.

In this study, we performed 252 experiments to investigate the influence of fabric thickness and material on the apparent 'wet' conductive (or effective) thermal resistance of the fabric 'skin' using a 'Newton' manikin. Four types of cotton fabric 'skin' (fabric thickness: 0.

To characterize viral nucleic acid in shellfish, oysters (Crassostrea ariakensis) were analyzed using viral metagenomics. Two large de novo assembled contigs, CaaDV1 and CaaDV2, consisting of nearly complete densovirus genomes (5860 nucleotides (nt) and 4034 nt) with two major ambisense protein coding regions were identified.

An electronic literature search was performed from inception to May 2015 and a total of 18,455 patients, enrolled in 62 recent studies, were included in this meta-analysis. Patients receiving LRYGB had a significantly higher percentage of excess weight loss and better resolution of hypertension, dyslipidemia, gastroesophageal reflux disease, and arthritis compared with those receiving LSG.

It is still a great challenge to develop PCSs that are portable, inexpensive, and effective. We studied the performance of a new hybrid PCS incorporating both ventilation fans and phase change materials (PCMs).

- Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are popular bariatric procedures used to treat morbid obesity, and this meta-analysis compares their effectiveness and safety.
- A systematic review of 32 studies with 6,526 patients showed that RYGB had a better impact on resolving obesity-related health issues like diabetes and hypertension, but it also had more complications and longer surgery times compared to SG.
- The study concludes that while RYGB is more effective in addressing comorbidities, SG offers a safer option with fewer complications and reoperations.
Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most widely used bariatric procedures, and laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for treating morbid obesity is becoming more popular. We compared both techniques to evaluate their efficacy in treating morbid obesity or type 2 diabetes mellitus (T2DM).
Methods: We searched the Cochrane Controlled Trials Register databases, Medline, Embase, ISI databases and the Chinese Biomedical Literature Database to identify randomized controlled trials (RCTs) of LRYGB and LSG for morbid obesity or T2DM published in any language.
Background: Previous reviews of the effectiveness of antibiotic prophylaxis for elective inguinal hernia repair were not conclusive owing to the limited number of patients enrolled in randomized controlled trials (RCTs). However, since new RCTs involving patients undergoing tention-free hernioplasty have been published in recent years, we performed a new meta-analysis to evaluate the effectiveness of antibiotic prophylaxisin the prevention of postoperative complications after this procedure.
Methods: We performed a meta-analysis of RCTs studying the use of antibiotic prophylaxis to prevent postoperative complications in patients undergoing tension-free hernioplasty.
Objective: Our aim was to investigate the effect of soy isoflavone (SI) on liver fibrosis in a thioacetamide (TAA)-induced rat model.
Materials And Methods: Twenty-eight rats were assigned to four groups: sham group, fibrosis group, low-dose treatment group (LDg) and high-dose treatment group (HDg). SI (90 or 270 mg/kg) was administered daily during the model development by TAA.
Background: Cardiac-specific deletion of ALK3 is lethal in mid-gestation with ventricular septum malformations (VSM). This study was designed to define the Pax-8's role in heart development and cardiomyocyte apoptosis.
Methods: Pathologic changes in the hearts of Pax-8 or ALK3 knockout and wild type control mice were determined by light and electron microscopy.
Objective: To investigate the differential expression profiles of microRNAs in the knockout Pax-8 mice by miRNA microarray analysis and study the function of microRNA during cardiac development.
Methods: The knockout Pax-8 mice model was established and the total RNA derived from Pax-8 KO-/- and Pax-8 KO+/- mice heart. MicroRNA microarray containing 567 mammalian microRNA probes was used to investigate the microRNAs differential expression between Pax-8 KO-/- and Pax-8 KO+/- mice.
