Modern-day consumers are interested in highly nutritious and safe foods with corresponding organoleptic qualities. Such foods are increasingly subjected to various processing techniques which include the use of enzymes. These enzymes like amylases, lipases, proteases, xylanases, laccases, pullulanase, chitinases, pectinases, esterases, isomerases, and dehydrogenases could be derived from extremophilic organisms such as thermophiles, psychrophiles, acidophiles, alkaliphiles, and halophiles.

Background: Granulosa cell ovarian tumors (GCTs) are a rare neoplasia characterized by a pathognomonic mutation in the FOXL2 gene. In vitro studies have demonstrated an overactivation of hormone activity due to this alteration. Thus, we aimed to determine the activity of orteronel, a CYP17 inhibitor, in advanced disease.

The growing demand for clean, decentralized energy has increased interest in blue energy, which generates power from water with different salt concentrations. Despite its potential as a renewable, low-cost energy source, optimizing electrode materials remains a challenge. This work presents a nanomaterial developed via microwave-assisted sol-gel methodology for blue energy applications, where ion diffusion and charge storage are critical.

Article Synopsis
  • Lyme disease in Argentina is currently not autochthonous, with no local cases reported, and its diagnosis involves a two-step serological testing algorithm.
  • From September 2014 to May 2022, a study analyzed 53 suspected cases, with all confirmed cases showing travel history to affected regions.
  • The results revealed a high rate of false positives (91%) from private laboratories, suggesting the need for careful diagnosis based on symptoms and approved testing methods.

Future carbon management strategies require storage in elemental form, achievable through a sequence of CO hydrogenation reactions. Hydrogen is recycled from molecular intermediates by dehydrogenation, and side product acetylene selectively hydrogenated to ethylene. Existing Pd alloy catalysts for gas purification underperform in concentrated feeds, necessitating novel concepts.

Article Synopsis
  • Immunotherapy, particularly when combined with chemotherapy, has shown limited effectiveness against solid tumors due to factors like cancer cells promoting immune cell exhaustion through nutrient diversion in the tumor microenvironment (TME).
  • The authors suggest using high doses of sodium citrate (SCT) alongside immune checkpoint inhibitors (ICIs) to inhibit cancer cell metabolism and enhance anti-tumor immune responses, as preclinical studies indicate SCT can reduce cancer growth and improve chemotherapy outcomes.
  • SCT works by increasing available glucose for immune cells and lowering lactic acid levels in the TME, which may enhance T cell activity and repolarize macrophages, indicating its potential to significantly boost the effectiveness of current immunotherapies in clinical settings.

Background: During diabetes, prorenin is highly produced by the renal collecting ducts. The binding of prorenin to (pro)renin receptor (PRR) on the apical plasma membrane triggers intracellular profibrotic genes, including TGF-β and CTGF. However, the underlying mechanisms contributing to the stimulation of these pathways remain unclear.

Macroalgae are known as abundant sources of phytochemicals, which offer a plethora of beneficial biological properties. Besides being the most notable classes of compounds found in macroalgae, phlorotannins, bromophenols, and terpenoids comprise some of the most relevant for their biological properties. Phlorotannins, mainly prevalent in brown algae and structurally characterized as complex polyphenolic compounds derived from phloroglucinol units, possess robust antioxidant, anti-inflammatory, antitumor, and cytotoxic activities, modulated by factors such as the degree of polymerization and environmental conditions.

This paper analyses the optimal control of infectious disease propagation using a classic susceptible-infected-recovered (SIR) model characterised by permanent immunity and the absence of available vaccines. The control is performed over a time-dependent mean reproduction number, in order to minimise the cumulative number of ever-infected individuals (recovered), under different constraints. We consider constraints on non-pharmaceutical interventions ranging from partial lockdown to non-intervention, as well as the social and economic costs associated with such interventions, and the capacity limitations of intensive care units that limits the number of infected individuals to a maximum allowed value.

Introduction: Small-cell lung carcinoma (SCLC) is a high-grade neuroendocrine carcinoma of poor prognosis. Although immune checkpoint blockers have shown promising results in advanced SCLC, the tumor immune microenvironment (TME) remains poorly understood, with no validated prognostic or predictive biomarkers of efficacy.

Methods: This retrospective study included surgically samples from 48 SCLC patients between 2009 and 2018.

Background: Processing environments can be an important source of pathogenic and spoilage microorganisms that cross contaminate meat and meat products. The aim of this study was to characterize the microbiome of raw materials, processing environments and end products from 19 facilities producing different meat products.

Results: The taxonomic profiles of the microbial communities evolved along processing, from raw materials to end products, suggesting that food contact (FC) surfaces play an important role in modulating the microbiome of final products.

The study aimed to evaluate the effect of digestion and gut microbiota interactions on beetroot ketchup formulations, focusing on the release of polyphenols, bioaccessibility, and microbial interactions on gut microbiota with polyphenols. Tested ketchup samples were evaluated using the TNO Gastro-Intestinal Model 1 (TIM-1) simulated upper part of the gastrointestinal tract and the TNO Gastro-Intestinal Model 2 (TIM-2) simulated colon system. The results showed that fermentation of ketchup with Lactobacillus johnsonii K4, increased the release of bioactive compounds during digestion, with higher polyphenol recoveries observed in fermented samples.
