The human gastrointestinal (GI) tract harbors many microorganisms, including viruses, protozoa, archaea, fungi, and bacteria. Altogether, these microbes constitute what we know as the gut microbiome (GM). These commensal communities have important implications for human health. They influence physiological processes through different mechanisms, including synthesizing neurotransmitters, regulating enzymatic pathways, and releasing molecules responsible for different signal pathways. The interaction between GM and b [...]

This paper suggests an approach for the use of a single paucicellular histological sample to investigate two characteristics indicative of the cell’s functional potential: 1) the content of telomerase reverse transcriptase (TERT) and 2) the telomere length. An algorithm has been suggested for the successive detection of the catalytic telomerase subunit with immunohistochemical staining and assessment of telomere length with Q-FISH on the same set of cells. The described approach uses three incontestable advantages [...]

Wheelchair basketball (WB) is a health and inclusion opportunity for people with disabilities. In the scientific literature, no evidence defines WB as a symmetrical or asymmetrical sport; however, it would be helpful to deepen this aspect because it could improve the quality of training programs and consequently speed up WB performance. In WB, the biomechanical role of the shoulders is crucial. Therefore, the symmetry index and the activation of the bilateral supraspinatus and biceps brachii muscles were investigat [...]

Keratinocytes are particularly vulnerable to oxidative stress due to their function as the primary natural protective barrier exposed to chemicals, rays, and pollution to stimulate the formation of free radicals in the body. Two factors of interest correlate with cellular senescence under oxidative stress. These include regulating antioxidant synthesis, which maintains free-radical homeostasis through the Nrf2 gene, and the prevention of telomere shortening, which involves the collaboration of human telomerase gene [...]

Falls are a serious global public health issue affecting individuals of all ages, resulting in serious injuries, fatalities, and extended hospital stays. While knowledge and attitude of healthcare staff toward fall prevention are understood to impact patient safety, less well known are the type and content of fall prevention surveys used to identify nurses’ knowledge of fall prevention. Until now, no study has systematically reviewed the universe of existing tests, surveys, and programs used to assess fall pr [...]

Moisl [1, 2] proposed a model of how the brain implements intrinsic intentionality with respect to lexical and sentence meaning, where 'intrinsic' is understood as 'independent of interpretation by observers external to the cognitive agent'. The discussion in both was mainly philosophical and qualitative; the present paper gives a mathematical account of the distance structure preservation that underlies the proposed mechanism of intrinsic intentionality. The three-layer autoassociative multilayer perceptron (aMLP) [...]

Microorganisms that are capable of degrading lignocellulolytic materials can produce extracellular cellulase complexes. Microorganisms are an excellent alternative for the production of cellulolytic complex, since these sources have a high power of multiplication. In this work, we researched the production by the fungus Moniliophthora perniciosa. The production and pH and temperature optimum optimization were studied by Response surface methodology and carboxymethylcellulase (CMCase) characterization. Thermal stabi [...]

This review intended to resume key Research reports and publications that open many themes and topics related to Carbon-based semiconductors and Quantum emitters. The Design and synthesis of highly pure materials such as Graphene, Carbon Nanotubes, fullerenes, and other Carbon-based allotropes were shown. They presented their most important and promising properties concerning new studies and developments in photonics. Carbon-based Quantum dots, semiconductors, and higher sized Nanoplatforms allowed us to discuss fu [...]

The gut microbiota, a complex ecosystem of billions of microorganisms in the human digestive tract, plays a crucial role in maintaining health. Recent studies have highlighted a bidirectional communication pathway called the gut-brain axis between the gut and the brain. This communication is significantly influenced by gut microbiota and its interactions with the immune system, which can affect brain function and contribute to inflammation. This study aims to provide a comprehensive overview of the relationship bet [...]
