Sodium lactate and acetic acid derivatives were evaluated for their effects on color retention, microbial growth, and sensory attributes of hot-boned pork sausage patties. Treatments included: (a) sodium lactate (L), (b) buffered vinegar (V), (c) sodium lactate and vinegar mixture (LV), (d) control with BHA/BHT (C), and (e) negative control (NC). Treatments L and LV decreased TPC at day 14 and day 16 when compared to control samples and reduced bacterial numbers up to 18 days. In addition, use of lactate and vinegar increased (P<0.05) acceptability and juiciness and reduced (P<0.05) off-flavor and rancidity when compared to control treatments at day 14. These results revealed that the L and LV sausage patties retained sensory acceptability and shelf-life quality from day 14 through day 17 as opposed to other treatments. Additionally, sausage patties with LV maintained redness and sensory quality throughout 17 days of shelf-life, as compared to other treatments that retained color and quality for 14 days.

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.
Hypoxia-Inducible Factor-1α Regulates BNIP3-Dependent Mitophagy and Mediates Metabolic Reprogramming Through Histone Lysine Lactylation Modification to Affect Glioma Proliferation and Invasion.

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.

Department of Cardiology, Aarhus University Hospital, Palle Juul-Jensens Boulevard 99, 8200, Aarhus N, Denmark.
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.
