Article Abstract
Purpose: Circulating TGF-β1 levels were found to be a predictor of delayed bone healing and non-union. We therefore aimed to investigate some factors that can influence the expression of TGF-β1. The correlation between the expression of TGF-β1 and the different socio-demographic parameters was analysed.
Methods: Fifty-one patients with long bone fractures were included in the study and divided into different groups according to their age, gender, cigarette smoking status, diabetes mellitus and regular alcohol intake. TGF-β1 levels were analysed in patient's serum and different groups were retrospectively compared.
Results: Significantly lower TFG-β1 serum concentrations were observed in non-smokers compared to smokers at week 8 after surgery. Significantly higher concentrations were found in male patients compared to females at week 24. Younger patients had significantly higher concentrations at week 24 after surgery compared to older patients. Concentrations were significantly higher in patients without diabetes compared to those with diabetes at six weeks after surgery. Patients with chronic alcohol abuse had significantly higher concentrations compared to those patients without chronic alcohol abuse.
Conclusion: TGF-β1 serum concentrations vary depending upon smoking status, age, gender, diabetes mellitus and chronic alcohol abuse at different times and therefore do not seem to be a reliable predictive marker as a single-point-in-time measurement for fracture healing.

As sheep production standards progress, and animals are bred for high production in terms of the number and weight of lambs weaned per ewe, research has identified a difference in the physiology of single lambs compared to multiple born lambs. The current study aimed to report the baseline amino acid (AA) profiles and blood gas concentrations in newborn, Merino single and twin lambs. From 120 days of gestation, 50 single-bearing and 50 twin-bearing, naturally mated Merino ewes were monitored for signs of approaching parturition.

Synthetic dyes, such as Congo red (CR), pose serious threats to human health and aquatic ecosystems because of their carcinogenicity and resistance to degradation, necessitating the development of efficient and eco-friendly remediation strategies. In this study, silver nanoparticles (AgNPs) were synthesized via a green method using Ocimum sanctum (holy basil) leaf extract and applied for CR dye removal from aqueous solutions. The adsorption process was optimized using response surface methodology (RSM) based on Box-Behnken design (BBD), evaluating the influence of key parameters including pH, AgNP dosage, initial dye concentration, contact time, and temperature.

Lucilia sericata (Meigen, 1826) maggot excretions/secretions (ES) have demonstrated anti-inflammatory and wound healing potential on corneal epithelial cells. This study aimed to evaluate the in vitro antibacterial potential of the ES against clinically relevant Gram-negative Pseudomonas aeruginosa and Gram-positive Staphylococcus epidermidis in the presence of human tear fluid. The ES was collected from sterile first- and second-instar L.

Human skeletal muscle comprises slow-twitch (type I) and fast-twitch (type II) fibers. Fiber type-specific analyses often require manual isolation of fibers, necessitating effective tissue preservation. While freeze-drying remains the standard, alternative preservation methods such as RNAlater and RNAlater-ICE are increasingly used.

Among the different forms of hydrotherapy, carbon dioxide (CO) water immersion improves peripheral vasodilation and blood flow compared with tap water immersion; however, the heat stress placed on the body through CO water immersion and the appropriate immersion protocols are uncertain. Therefore, this study aimed to compare the thermoregulatory responses during CO and tap water immersions. The participants were 10 male college baseball players.
