The profile of oxidative stress markers (arachidonic and linoleic acid derivatives) in patients with benign prostatic hyperplasia in relation to metabolic syndrome.

So far, it has been proven that benign prostatic hyperplasia (BPH) is strongly associated with inflammation resulting from, i.a. the presence of infectious agent, autoimmune disease, aging process and lipid disorders associated with metabolic syndrome (MetS).

Impedimetric Sensor for SARS-CoV-2 Spike Protein Detection: Performance Assessment with an ACE2 Peptide-Mimic/Graphite Interface.

The COVID-19 pandemic has prompted the need for the development of new biosensors for SARS-CoV-2 detection. Particularly, systems with qualities such as sensitivity, fast detection, appropriate to large-scale analysis, and applicable in situ, avoiding using specific materials or personnel to undergo the test, are highly desirable. In this regard, developing an electrochemical biosensor based on peptides derived from the angiotensin-converting enzyme receptor 2 (ACE2) is a possible answer.

Functional interactions among H2O2, NO, H2S, and melatonin in the physiology, metabolism, and quality of horticultural Solanaceae.

Cellular signaling is a key component of both intra- and intercellular communication, playing a crucial role in the development of higher plants as well as in their responses to environmental conditions of both abiotic and biotic origin. In recent decades, molecules such as hydrogen peroxide (H2O2), nitric oxide (NO), hydrogen sulfide (H2S), and melatonin have gained significant relevance in plant physiology and biochemistry due to their signaling functions and their interactions, forming a comprehensive cellular communication network. The Solanaceae family of plants includes a group of horticultural crops of great global importance, for instance, tomatoes, eggplants, and peppers, which are of major agroeconomic significance due to their widespread cultivation and consumption.

Characterization of Platelet Receptors and Their Involvement in Immune Activation of These Cells.

The article characterises platelets, pointing out the role and contribution of their numerous receptors determining their specific and broad immune activity. Three types of platelet receptors are described, that is, extracellular and intracellular receptors-TLR (toll-like receptors), NLR (NOD-like receptor), and RLR (RIG-I-like receptor); extracellular receptors-selectins and integrins; and their other extracellular receptors-CLR (C-type lectin receptor), CD (cluster of differentiation), TNF (tumour necrosis factor), among others. Outlining the contribution of these numerous platelet receptors to the intravascular immunity, it has been shown that they are formed by their fusion with pathogen-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs), and lifestyle-associated molecular patterns (LAMPs).

Production and Optimization of LTE, a Leishmania tarentolae Derived Cell-Free Protein Expression System for Recombinant Protein Production.

This protocol outlines the production and optimization of a eukaryotic Cell-Free Protein Expression System (CFPS) derived from the unicellular flagellate Leishmania tarentolae, referred to as Leishmania Translational Extract or LTE. Although this organism originally evolved as a parasite of geckos, it can be cultivated easily and inexpensively in flasks or bioreactors. Unlike Leishmania major, it is non-pathogenic to humans and does not require special laboratory precautions.
