HTLV-1 Tax Structure Models
Human T-cell Leukemia Virus type 1 (HTLV-1) is a human retrovirus responsible for leukaemia in 5 to 10% of infected individuals. Among the viral proteins, Tax has been described as directly involved in virus-induced leukemogenesis. Tax is therefore an interesting therapeutic target. However, its 3D structure is still unknown and this hampers the development of drug-design-based therapeutic strategies. Several algorithms are available that can be used to predict the structure of proteins, particularly with the recent appearance of artificial intelligence (AI)-driven pipelines. However, Tax seems to be resistant to such predictions.

Lignocellulolytic Microorganisms in Cereal Crop Residue Decomposition
The global escalation in cereal production, essential to meet growing population demands, simultaneously augments the generation of cereal crop residues, estimated annually at approximately 3107 × 106 Mg/year. Among different crop residue management approaches, returning them to the soil can be essential for various ecological benefits, including nutrient recycling and soil carbon sequestration. However, the recalcitrant characteristics of cereal crop residues pose significant challenges in their management, particularly in the decomposition rate. Microorganisms employ a range of mechanisms, such as the utilization of different enzymes that work in combination, to initiate oxidative attacks on plant litter. Consequently, this serves to reduce the recalcitrance of the lignocellulosic material, hence facilitating subsequent action by depolymerizing enzymes. Both fungi and bacteria have received increased attention for their ability to secrete a diverse range of lignocellulolytic enzymes.

Biological Role of FAM111A and FAM111B
Proteases are critical enzymes in cellular processes that regulate intricate events like cellular proliferation, differentiation, and apoptosis. FAM111A is implicated in DNA replication and replication fork protection, thereby maintaining genome integrity. Additionally, FAM111A functions as an antiviral factor against DNA and RNA viruses. FAM111B, a paralog of FAM111A, participates in cell cycle regulation and apoptosis. It influences the apoptotic pathway by upregulating anti-apoptotic proteins and modulating cell cycle-related proteins. Furthermore, FAM111B’s association with nucleoporins suggests its involvement in nucleo-cytoplasmic trafficking and plays a role in maintaining normal telomere length. FAM111A and FAM111B also exhibit some interconnectedness and functional similarity despite their distinct roles in cellular processes and associated diseases resulting from their dysfunction.

Astrocytes and α-Syn in Parkinson’s Disease
The α-syn protein is a 140-amino-acid protein that comprises an N-terminal region that assumes an α-helical secondary structure upon membrane binding, a non-amyloid-component hydrophobic domain that can adopt a β-sheet conformation, promoting protein aggregation in its monomeric form, and a negatively charged C-terminal domain. Astrocytes greatly contribute to neuronal survival through numerous mechanisms, such as the secretion of neurotrophins and antioxidants, the clearance of α-synuclein, glutamate metabolism, fatty acid metabolism, and the transfer of healthy mitochondria to neurons.

Influence of Alcohol on Intracerebral Hemorrhage
Alcohol, a key part of human culture since ancient times, has various uses ranging from beverages to antiseptics and fuels. Different types of alcoholic beverages such as wine and beer, being the oldest and probably the most widely used drugs, were known for their therapeutic value in addition to the vital part they played in the daily life of people in ancient times. A standard alcohol unit, used to measure drinking consistently, varies globally. The World Health Organization (WHO) suggests that a standard drink contains 10 g of pure ethanol per day, though this varies (8–20 g) across countries.

Dairy Cow Health and Methane Emissions
The dairy industry is facing criticism for its role in exacerbating global GHG emissions, as climate change becomes an increasingly pressing issue. These emissions mostly originate from methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2). An optimal strategy involves the creation of an economical monitoring device to evaluate methane emissions from dairy animals.

Antioxidant Activities of Mentha spp. Essential Oils
Plant essential oils (EOs) are produced predominantly using steam distillation, but can also be generated using fermentation, crushing, extraction, hydrolysis, and airing. EOs are used extensively in cosmetics in many different aspects as perfumes, in antiseptic applications, and in domestic cleaning products. The essential oils of Mentha (the Lamiaceae family) have been extensively studied for their biological actions.

Health Benefits of Phenolic Compounds from Pigmented Corn
Pigmented corn is a gramineae food of great biological, cultural and nutritional importance for many Latin American countries, with more than 250 breeds on the American continent. It confers a large number of health benefits due to its diverse and abundant bioactive compounds. Phenolic compounds, among which are anthocyanins are some of the most studied and representative compounds in these grasses, with a wide range of health properties, mainly the reduction of pro-oxidant molecules.

Ant–Pollinator Conflict in Extrafloral Nectary-Bearing Plants
The net outcomes of mutualisms are mediated by the trade-offs between the costs and benefits provided by both partners. This trade-off has important implications for understanding the evolution of extrafloral nectaries (EFNs), an adaptation that has repeatedly evolved throughout the flowering plant clade.

Impact of Heat-Stress-Induced Oxidative Stress and Apoptosis
Heat stress represents a pervasive global concern with far-reaching implications for the reproductive efficiency of both animal and human populations. An extensive body of published research on heat stress effects utilizes controlled experimental environments to expose cells and tissues to heat stress and its disruptive influence on the physiological aspects of reproductive phenotypic traits, encompassing parameters such as sperm quality, sperm motility, viability, and overall competence. Beyond these immediate effects, heat stress has been linked to embryo losses, compromised oocyte development, and even infertility across diverse species. One of the primary mechanisms underlying these adverse reproductive outcomes is the elevation of reactive oxygen species (ROS) levels precipitating oxidative stress and apoptosis within mammalian reproductive cells. Oxidative stress and apoptosis are recognized as pivotal biological factors through which heat stress exerts its disruptive impact on both male and female reproductive cells. In a concerted effort to mitigate the detrimental consequences of heat stress, supplementation with antioxidants, both in natural and synthetic forms, has been explored as a potential intervention strategy. Furthermore, reproductive cells possess inherent self-protective mechanisms that come into play during episodes of heat stress, aiding in their survival.
