Production of primary metabolites by Pseudomonas reptilivora B-6bs at the flask level using a full factorial experimental design.

The metabolites gluconic acid, 5-ketogluconic acid, proline, and glutamic acid, produced by Pseudomonas reptilivora B-6bs, are industrially important, particularly in food and pharmaceutical sectors. However, producing these metabolites involves biotin supplementation to enhance yields, which is an expensive additive, and reducing its use can significantly lower production costs. Thus, This study aimed to enhance the production of gluconic acid, 5-ketogluconic acid, proline, and glutamic acid without biotin supplementation.

The effect of hyperbaric oxygen therapy on oxidative stress and inflammation in patients with diabetic foot ulcers: A preliminary study.

Introduction: Patients with an uncontrolled glycemic index develop a wide variety of pathologies associated with diabetes, such as diabetic foot ulcers (DFUs). Hyperbaric oxygen therapy (HBOT) is an adjunctive therapy used to heal wounds and prevent lower extremity amputations in this population.

Objective: This preliminary study aimed to evaluate how HBOT impacts inflammation in patients with Wagner stages 2-4 DFUs by analyzing its effect on the gene expression of key oxidative stress regulators SOD1, SOD2, and GPX2, of pro-inflammatory cytokines TNFα, IL-1β, IL-4, and IL-12, and of the NLRP3 inflammasome.

The usefulness of a 28-item Therapeutic Intervention Scoring System (TISS-28) in critically ill obstetric patients to detect multiorgan dysfunction: A prospective cohort study.

Background: This study evaluated the effectiveness of the 28-item Therapeutic Intervention Scoring System (TISS-28) in detecting multiorgan dysfunction (MOD) among critically ill obstetric patients and compared its predictive potential to other severity models, such as Sequential Organ Failure Assessment (SOFA) and Mortality Probability Model II (MPM II).

Methods: A prospective multicentre cohort study was conducted including obstetric patients, pregnant and up to 42 days postpartum, admitted to the intensive care units of two referral hospitals in Colombia. A total of 93 patients were recruited between March 2016 and February 2017 and from September 2019 to November 2019.

Evaluation of the Effect of Growth Factors on Chlorophylls a and b Production from Microalgae.

Microalgae contain two main groups of pigments: chlorophylls and carotenoids. Chlorophyll is a green pigment that absorbs light energy and transforms it into chemical energy to facilitate the synthesis of organic compounds. This pigment serves as a valuable primary source for biotechnological input products in the food, pharmaceutical, and cosmetic industries due to its high antioxidant properties and coloring capabilities.
