Galeus melastomus
We reviewed literature on the diet of the Galeus melastomus Rafinesque, 1810, from the Mediterranean Sea. Specific keywords (“Galeus melastomus diet”, “feeding habits”, “trophic position”, “biology”, “deep environment adaptation”) in the principal data sources, such as Web of Science, PubMed, and Google Scholar were used. Seventeen studies conducted on the diet and trophic position of G. melastomus have been considered for Mediterranean Sea regions. The feeding habits have been analyzed in many areas of the western basin; instead, for the Tyrrhenian, Adriatic, and central Mediterranean Seas, information is outdated and fragmentary. In all investigated sub areas, the data showed that G. melastomus is an opportunistic demersal supra benthic predator, benthic feeder, and scavenger, that adapts its diet to the seasonal and geographical fluctuations of the prey availability. It occupies a generalist niche showing individual specialization. In all reviewed Mediterranean sub areas, the most important prey groups were crustaceans, cephalopods, and teleost fishes. Taxa percentage in its diet composition can vary depending on different habitats with ontogenetic development of individuals, depth (that is correlated with the ontogenetic development), seasonal availability, and distribution of different prey groups.

Restoration of Rangelands
Abandonment of agricultural land is currently one of the main land use changes in developed countries. This change has an impact at the economic level and from the point of view of conservation. Therefore, recovering these areas after abandonment is, in many cases, necessary for ecological restoration, especially as they can be invaded by exotic or dominant species, preventing recovery of the original plant species community. The objective of this study is to examine changes in plant species richness and composition after the application of different treatments to eliminate Amelichloa clandestina, a species that dominates pastures abandoned 12 years ago in an area located in northern Mexico. The area is a semi-desert grassland dominated by buffalo grass Bouteloua dactyloides.

PIVKA-II, Canine Tissues, Anticoagulant Poisoning
PIVKA-II is an aberrant form of vitamin K that has been demonstrated to be increased in human coagulation disorders and in some neoplastic diseases. In veterinary medicine, PIVKA-II levels have been demonstrated to be useful for distinguishing anticoagulant poisoning from other coagulopathies. In forensic pathology, there is the need to distinguish malicious poisoning from other causes of death and, in some cases, identifying poisoned dogs from dogs that died as a result of other coagulative disorders can be challenging. This study evaluated the usefulness of the immunohistochemical expression of PIVKA-II in hepatic and renal tissues in order to identify patients with coagulative disorders due to clinical condition or the ingestion of anticoagulants substances.

Quinoa for the Brazilian Cerrado
Quinoa stands out as an excellent crop in the Cerrado region for cultivation in the off-season or irrigated winter season. Quinoa (Chenopodium quinoa Willd.) is a pseudocereal rich in natural antioxidants, flavonoids, and anthocyanins, and these compounds may protect plants against biotic and abiotic stress. Water stress increases leaf temperature, and reduces crop height, stomatal conductance, plant biomass, and yield. Here, we tested the effects of different water regimes on the agronomic characteristics, physiology, and grain quality of different elite quinoa genotypes under field conditions.

Chinese College Students’ Attitudes towards Animal Welfare
College students, specifically from veterinary, animal, agricultural, and life sciences majors represent the future professionals who will closely work with animal industry stakeholders. Therefore, it is important to understand their attitudes towards animals and their knowledge about animal welfare. A survey on Chinese college students was conducted across different majors and Chinese geographical regions to understand their attitude towards the animal Sentient and the Five Freedoms models for pets, laboratory, farm, and wild animals. Most of the respondents exhibited a good attitude towards both the animal Sentient and the Five Freedoms models, with best scoring for pet animals followed by wild animals. Respondents showed less concerns towards farm and laboratory animals. A previous animal welfare education, the ownership of animals, and the participation in laboratory work involving animals positively influenced the attitude of the respondents towards animal welfare.

Musty and Moldy Taint in Wines
The literature about musty and moldy taint—the so-called cork taint—in wines is varied because there are many different molecules involved in this wine defect. Chloroanisoles are the most relevant compound responsible for cork taint and of these, 2,4,6-trichloroanisole (TCA) is the most common, but 2,3,4,6-tetrachloroanisole (TeCA) and 2,4,6-tribromoanisole (TBA) can also be responsible of this defect. For other compounds involved in cork taint, geosmin and 2-methylisoborneol (2-MIB) are responsible for earthy off-flavor; pyrazines cause vegetable odors, and guaiacol results in smoked, phenolic and medicinal defects. Off-odors of mushroom in wines are caused by 1-octen-3-ol and 1-octen-3-one coming from grapes contaminated by bunch rot (Botrytis cinerea).

PRRS Immune Control Strategies
Porcine reproductive and respiratory syndrome (PRRS) affects farmed pigs worldwide and still causes heavy direct and indirect losses. The syndrome emerged in the late 1980s, in USA, and later on in Europe, and it eventually became enzootic in most countries among farmed pigs. Late-term reproductive failure in sows with transplacental transmission of the virus, preweaning mortality of piglets, respiratory distress, anorexia, and possible cutaneous hyperemia in weaners and growers are common clinical signs of PRRS.

Toxic Mechanism of Fumonisins
Fumonisins are widely found in animal feed, feed raw materials, and human food. This can not only cause economic losses in animal husbandry but can also have carcinogenicity or teratogenicity and can be left in animal meat, eggs, and milk which may enter the human body and pose a serious threat to human health. Fumonisins cause a variety of toxic effects to organisms including autophagy, apoptosis, neurotoxicity, immunotoxicity, reproductive toxicity, tissue and organ toxicity, and carcinogenicity. They can not only cause disease alone but also have a combined toxic effect with other mycotoxins such as aflatoxins. The toxicity of fumonisins is a very complex process. Previous studies report that fumonisins exert their toxicity by modulating sphingolipid metabolism and inducing oxidative stress

Rendzinas of the Russian Northwest
Rendzinas in the taiga zone are intrazonal soils; moreover, all of their processes occur in ways that are different from podzolic soil formation, which is typical for the zonal taiga boreal ecosystem. At the same time, the habitats of carbonate soils are known as places in which there is a concentration of biodiversity in the more southern regions, as they are drier, are insolated, and have a higher trophic state than zonal podzols. The biotopes on carbonate soils are becoming more southern and are dominated by nemoralis species of flora, including abundant calciphilous plant species. Carbonate soils regulate biogeochemical processes within their distribution and in the geochemically subordinate landscapes of Northwest Russia. They are associated with the existence of a number of specially protected natural areas, as well as the implementation of a number of important ecosystem services. Carbonate soils of the southern taiga are endangered and require special protection. The belt of the carbonate soils in the northwestern Russian and Baltic regions extends to Poland and is the basis for the formation of a special landscape–ecological framework with specific biodiverse, biogeochemical, and geographical characteristics.

Antimicrobial Stewardship under Global Framework
Antimicrobials are naturally occurring semi-synthetic or synthetic substances that kill or inhibit the replication of microorganisms. Remarkable achievements have been reached in human medicine due to the availability and efficacy of antimicrobials, from the treatment of previously fatal infections to surgical procedures, otherwise impossible. Promoting and supporting antimicrobial stewardship (AMS) at the global, national, and local levels is dependent on building strong supporting pillars. From the Food and Agriculture Organization (FAO) perspective, these pillars are (1) awareness, (2) governance, (3) practices, and (4) surveillance.

Extracellular Vesicles from Animal Milk
Milk represents the main source of nutrition for newborn mammals and serves as the conveyor of maternal messages of a sophisticated signaling system to promote postnatal health. It contains bioactive components that are essential for the development of the newborn immune system such as oligosaccharides, lactoferrin, lysozyme, alpha-lactalbumin, and immunoglobulins. Extracellular vesicles (EVs) were identified to be pivotal in this mother-to-child exchange. EVs are micro- and nanosized structures enclosed in a phospholipidic double-layer membrane that are produced by all cell types. They are released in the extracellular environment and reach close and distant cells. EVs can induce the modulation of biological processes in receiving cells after their absorption through the release of the molecular cargo contained within vesicles. In this way, EVs can also serve through immunomodulant anti-inflammatory, angiogenetic, and pro-regenerative actions depending on the cell of origin and patho/physiological conditions. EVs can be recovered from all biological fluids including milk.

Mechanism of Melatonin in Horticultural Plants
It has been discovered that melatonin, a hormone that is known for its involvement in regulating sleep-wake cycles in mammals, has a range of different functions in horticultural plants. Research has shown that melatonin plays an important role in many physiological processes in plants. This includes the regulation of growth and development, stress tolerance and antioxidant defense. Melatonin has been found to be beneficial in supporting seed germination, roots, shoot growth and biomass accumulation in horticultural crops. It also has a key role in regulating vegetative and reproductive growth stages, floral transition and leaf senescence. Moreover, melatonin helps to improve stress tolerance in crops by regulating root architecture, nutrient uptake and ion transport. Additionally, melatonin acts as a broad-spectrum antioxidant by effectively scavenging reactive oxygen species and enhancing antioxidant activity. The mechanism of melatonin's action in horticultural plants involves gene expressions, hormone signaling pathways and antioxidant defense pathways. Melatonin interacts with other plant growth regulators, including auxins, cytokinins and abscisic acid, to coordinate different physiological processes in plants. Melatonin has become a versatile chemical entity with diverse functions in horticultural plants and its potential applications in crop production and stress management are being increasingly explored.
