The efficacy of using additives to improve the shelf life of low-fat (approximately 18%) Chinese-style sausages was demonstrated. Sausages containing 3% sodium lactate (SL), 0.2% trisodium phosphate (TSP) or 0.2% potassium sorbate (KS) compared with the control (CONT) were manufactured and stored at 4°C for 12 weeks. Treatment TSP was the highest in pH during any storage intervals. Generally speaking, all microbial counts were lower for SL but higher for TSP; nonetheless, all treatments had bacterial counts less than 10(7) CFU/g. Low-fat Chinese-style sausage containing 3% sodium lactate resulted in better quality regarding physicochemical and microbiological characteristics. Results also suggested a potential utilization of sodium lactate as an antimicrobial agent.

Background/objectives: rapidly acquires antibiotic resistance and demonstrates increasing tolerance to antiseptics. This study evaluated the activity of eight antiseptics against , assessed its ability to develop adaptation to these antiseptics, and, for the first time, determined the Karpinski Adaptation Index (KAI) for this bacterium.
Methods: The minimal inhibitory concentration (MIC), susceptibility to antibiotics, bactericidal time according to EN 1040:2005, adaptation potential, and KAI of strains were evaluated.

This systematic review and meta-analysis evaluated the effects of sodium bicarbonate (NaHCO₃) supplementation on 200 m time trial performance and physiological responses in swimmers, following PRISMA guidelines. A comprehensive search across five databases identified eligible randomized controlled trials comparing NaHCO₃ with placebo. Outcomes were 200 m time, blood bicarbonate, blood lactate, and blood pH.

Background: Venous blood gas and acid-base analysis is often performed in cats and requires appropriate reference intervals (RIs) for interpretation. The currently available RIs were created from small numbers of cats, while current guidelines suggest that a minimum number of 40 samples is required for the creation of an accurate/appropriate RI.
Key Findings: In 41 healthy awake cats, pH, PCO, PO, sodium, potassium, ionized calcium, chloride, glucose, and plasma lactate concentrations were measured, while bicarbonate, standardized base excess, and anion gap were calculated.

Objective: Gliomas are the predominant form of malignant brain tumors. We investigated the mechanism of hypoxia-inducible factor-1α (HIF-1α) affecting glioma metabolic reprogramming, proliferation and invasion.
Methods: Human glioma cell U87 was cultured under hypoxia and treated with small interfering (si)HIF-1α, si-B cell lymphoma-2/adenovirus E1B 19-kDa interacting protein 3 (siBNIP3), si-YT521-B homology domain 2 (siYTHDF2), 3-methyladenine and 2-deoxyglucose, with exogenous sodium lactate-treated normally-cultured cells as a lactate-positive control.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.
