EIF5A in Mitochondrial Function
The eukaryotic translation initiation factor 5A (eIF5A) is an evolutionarily conserved protein that binds ribosomes to facilitate the translation of peptide motifs with consecutive prolines or combinations of prolines with glycine and charged amino acids. It has also been linked to other molecular functions and cellular processes, such as nuclear mRNA export and mRNA decay, proliferation, differentiation, autophagy, and apoptosis. The growing interest in eIF5A relates to its association with the pathogenesis of several diseases, including cancer, viral infection, and diabetes. It has also been proposed as an anti-aging factor: its levels decay in aged cells, whereas increasing levels of active eIF5A result in the rejuvenation of the immune and vascular systems and improved brain cognition. Data have linked the role of eIF5A in some pathologies with its function in maintaining healthy mitochondria. The eukaryotic translation initiation factor 5A is upregulated under respiratory metabolism and its deficiency reduces oxygen consumption, ATP production, and the levels of several mitochondrial metabolic enzymes, as well as altering mitochondria dynamics. However, although all the accumulated data strongly link eIF5A to mitochondrial function, the precise molecular role and mechanisms involved are still unknown.

Cathepsin S in Rabbits's cells
In goat and sheep, CTSS is reported to be important for the development and maturation of oocytes by regulating cell proliferation and apoptosis. The purpose of this study was to investigate the role of CTSS in regulating cell apoptosis and hormone secretion in rabbit granulosa cells. Our results suggested that the CTSS gene can promote the proliferation of granulosa cells and reduce its apoptosis in vitro, while overexpression of CTSS promoted the secretion of progesterone and estrogen in rabbit granulosa cells. Therefore, manipulation of CTSS may improve development of oocytes, and thus provide an approach for better manipulation of rabbit reproductive performance.

Wholegrain Rice and Human Nutrition
Rice is one of the most widely consumed cereals in the world. The husks of harvested, unprocessed rice are not digested by humans and need to be removed to obtain edible grains, whereas the bran can be partially (brown rice) or totally removed (white rice). Brown rice is a wholegrain cereal and, as such, is known to have beneficial effects on human health.

Heat Tolerance in Common Wheat
Heat tolerance (HT) in plants is the capacity of plants to tolerate heat stress. It is a quantitative trait involving complex genetic, physiological, and biochemical controls and is affected by environmental factors. In response to heat stress, tolerant varieties generally activate an antioxidant defence system, express heat shock proteins (HSPs) and reduce senescence by staying green.

Plant Growth Promoting Microorganisms in Soilless Systems
Soilless systems, such as hydroponics and aquaponics, are gaining popularity as a sustainable alternative to traditional soil-based agriculture, aiming at maximizing plant productivity while minimizing resource use. Plant growth-promoting microorganisms (PGPM) have emerged as a promising solution to overcome these issues. Bacillus, Pseudomonas, and Azospirillum are the most extensively studied genera for their effectiveness as growth promoters, inducing changes in root architecture morphology. Furthermore, PGPM inoculation, either alone or in synergy, can reverse the effects of nutrient deficiency and salt stress. The genera Pseudomonas and Trichoderma were recognized for their solid antagonistic traits, which make them highly effective biocontrol agents in hydroponic systems. The findings indicate their ability to significantly reduce disease severity index (DSI) through mycoparasitism, antibiosis, and induced systemic resistance. In aquaponic systems, the inoculation with Bacillus subtilis and Azospirillum brasilense demonstrated increased dissolved oxygen, improving water quality parameters and benefiting plant and fish growth and metabolism.

Aphrophoridae Role in Xylella fastidiosa Invasion in Italy
The Philaenus spumarius L. (Hemiptera Aphrophoridae) is a xylem-sap feeder vector that acquires Xylella fastidiosa subsp. pauca ST53 during feeding on infected plants. The bacterium is the plant pathogen responsible for olive quick decline syndrome that has decimated olive trees in Southern Italy. Damage originates mainly from the insect vector attitude that multiplies the pathogen potentialities propagating Xf in time and space. The principal action to manage insect borne pathogens and to contain the disease spread consists in vector and transmission control. The analysis of an innovative and sustainable integrated pest management quantitative strategy that targets the vector and the infection by combining chemical and physical control means demonstrates that it is possible to stop the Xylella invasion. This entry updates the available topics addressing vectors' identification, bionomics, infection management, and induced disease by Xylella invasion to discuss major available tools to mitigate the damage consequent to the disease.

Problems in Paddy Procurement System in Bangladesh
Bangladesh derives one-half of its agricultural GDP and one-sixth of its national income from paddy. It is crucial to the farmers’ ability to survive. The majority of farmers in Bangladesh are classified as middle- or low-income. They must frequently take out loans to cultivate paddy. Moreover, they are compelled to sell their paddy at a lower price immediately after harvesting for primarily two reasons: the lack of storage facilities; and the immediate need for money to pay back loans taken out to buy labour, seeds, fertiliser, insecticides, and other necessities, and to fund daily costs.

Biological Processes of Designing Candidate Anti-Tick Vaccines
Ticks are obligate hematophagous arthropod ectoparasites distributed worldwide, and belong to two families; Ixodidae (hard-bodied ticks) and Argasidae (soft-bodied ticks). They affect 80% of the world’s cattle population and are associated with numerous health and economic effects. In developing tropical countries, tick-borne diseases (TBDs) constitute a major constraint to the livestock production, especially among smallholder farms of East, Central and Southern Africa.

Probiotics as a Friendly Antibiotic Alternative
The improvement of feed consumption and genetic selection have been the primary areas of poultry research. The control of a variety of microbial infectious diseases caused by Streptococcus, Staphylococcus, Escherichia coli, Pseudomonas, Campylobacter, Salmonella, Yersinia, Bacillus, Clostridium, Mycobacterium, Enterococcus, Klebsiella and Proteus species has been less thoroughly investigated. The immune system of broilers is not fully developed during the first few weeks and therefore it is more susceptible to bacterial infection. Furthermore, it can take up to eight weeks for the gut microbiota to develop and stabilize. The longer the time necessary to reach bacterial homeostasis, the greater the risk of bacterial infection. Poultry are kept in closed facilities to minimize the risk of bacterial infection.

Fluorescent Tracers by Soybean
Systemic seed treatment uptake was investigated in seeds and seedlings using fluorescent tracers to mimic systemic agrochemicals. Soybean was used as the model as soybean has the permeable seed coat characteristic to both charged and noncharged molecules. The purpose of the paper is to (1) screen 32 fluorescent tracers and then use optimal tracers for seed and seedling uptake, (2) investigate varietal differences in seed uptake, (3) examine the distribution of tracer uptake into 14-day-old seedlings, and (4) study the relationship between seed treatment lipophilicity, measured as log P on seed and root uptake. The major chemical families that displayed both seed and seedling uptake were coumarins and xanthenes. Seed uptake of coumarin 120 ranged from 1.1% to 4.8% of the applied seed treatment tracer from 15 yellow-seeded varieties. Rhodamine B, a xanthene compound uptake in seedlings, showed translocation from the applied seed treatment to all seedling tissues. Most of the tracer was measured in the hypocotyl and root, with lesser amounts in the epicotyl and true leaves. Log P is well documented in the literature to model systemic uptake by roots, but log P of the tracers were not related to seed uptake.

The Effect of Music on Livestock
The welfare of animals, especially those kept in intensive production systems, is a priority for modern agriculture. This stems from the desire to keep animals healthy, to obtain a good-quality final product, and to meet the demands of today’s consumers, who have been increasingly persuaded to buy organic products. As a result, new sound-based methods have been pursued to reduce external stress in livestock. Music therapy has been known for thousands of years, and sounds were believed to improve both body and spirit. Today, they are mostly used to distract patients from their pain, as well as to treat depression and cardiovascular disorders. However, recent studies have suggested that appropriately selected music can confer some health benefits, e.g., by increasing the level and activity of natural killer cells. For use in livestock, the choice of genre, the loudness of the music and the tempo are all important factors. Some music tracks promote relaxation (thus improving yields), while others have the opposite effect.

Application of Campylobacter jejuni Phages
Campylobacter jejuni is a zoonotic bacterial pathogen found in abundance, e.g., in raw poultry. C. jejuni is part of the avian gut microbiome, causing no harm to birds. When birds are slaughtered, the bacterium is released from the intestines and contaminates the meat. Cross-contaminated foods processed in parallel to the meat cause diarrhea in humans and in rare cases may cause post-infectious complications like arthritis and paralysis of peripheral nerves. Illnesses caused by C. jejuni have been on the rise in both developed and developing countries. At the same time, C. jejuni has acquired resistance to important antibiotics, which further complicates therapeutic approaches. To decrease the Campylobacter load on chicken carcasses, chemical or thermal treatment can be used. However, this may change the taste or affect the appearance of chicken meat.

Innate Immune Cells in the Chicken Intestine
The chicken intestinal epithelium is a monolayer consisting of various cell types. Intercellular junctional complexes, tight junctions, present between the intestinal epithelial cells maintain the gut barrier integrity. Tight junctions hold the intestinal epithelial cells together to prevent the entry of enteric pathogens and thus maintain gut homeostasis. In addition to the gut microbiota, also intestinal epithelial cells inhibit the entry of pathogens for example by producing a mucus layer. In addtion to this physical barreier, also soluble factors suc a antimicrobial compunds play a role in the defence against pathogens. When all these defense mechanism are not sufficient in protecting the host, the cells of the intestinal innate immune system are activated. Properties and function of these cells are the subject of this entry.

Artificial Intelligence Impact Affective State Recognition in Livestock
Farm animals, numbering over 70 billion worldwide, are increasingly managed in large-scale, intensive farms. With both public awareness and scientific evidence growing that farm animals experience suffering, as well as affective states such as fear, frustration and distress, there is an urgent need to develop efficient and accurate methods for monitoring their welfare. At present, there are not scientifically validated ‘benchmarks’ for quantifying transient emotional (affective) states in farm animals, and no established measures of good welfare, only indicators of poor welfare, such as injury, pain and fear. Conventional approaches to monitoring livestock welfare are time-consuming, interrupt farming processes and involve subjective judgments. Biometric sensor data enabled by artificial intelligence is an emerging smart solution to unobtrusively monitoring livestock, but its potential for quantifying affective states and ground-breaking solutions in their application are yet to be realized.

Minerals and Cancer
Minerals and trace elements are important micronutrients for normal physiological function of the body. They are abundant in natural food sources and are regularly included in dietary supplements whereas highly processed industrial food often contains reduced or altered amounts of them. In modern society, the daily intake, storage pools, and homeostasis of these micronutrients are dependent on certain dietary habits and can be thrown out of balance by malignancies. Their dietary imbalance, which is becoming more common in the diets of industrialized countries, is linked to an increased risk of cancer.
