Since the first successful kidney transplant in 1954, transplant medicine has made enormous progress. Until today, there are numerous patients worldwide waiting for an organ to be transplanted, and the number is still increasing, whereas the number of available organs is decreasing. One promising solution to this critical issue is the breeding of genetically modified animals as potential donors, which has gained the attention of scientists over the past two decades. Recent advancements in xenotransplantation have led to successful transfers of genetically modified pig organs into human recipients. Particularly, pig kidneys have been transplanted into living humans, demonstrating normal postsurgical function. Additionally, pig lungs functioned for 9 days in a brain-dead individual without experiencing hyperacute rejection. Furthermore, the successful xenotransplantation of pig hearts into living persons, exhibiting life-sustaining graft function, underscores significant progress toward clinically viable xenotransplants. This review provides an updated overview of the animal species and models used in xenotransplantation, with particular emphasis on the potential of transgenic pigs as donors. It discusses the process involved in producing the aforementioned animals, including the methods used to modify their genome. Particular attention is paid to immunological and genetic barriers, as well as zoonotic risks, and the possibilities and limitations of this technology. Although xenotransplantation is still in its experimental stage, it may play a crucial role in saving patients ' lives in the future.展开更多

However, the characteristics of CAR content and its influencing factors across different marine animal species remain poorly understood. This study examined the CAR content in 258 marine animals, representing 54 species across seven classes, collected from coastal and offshore regions of China and the Northwest Pacific Ocean(NWPO) between May 2020 and June 2022. The CAR content ranged from0.01 mmol/kg to 1.33 mmol/kg, with a mean value of(0.15 ± 0.18) mmol/kg(mean ± standard deviation). The highest CAR content was observed in Crustacea [(0.48 ± 0.38) mmol/kg], which was four times greater than the average CAR content in the other classes [(0.12 ± 0.11) mmol/kg]. Overall, the CAR content exhibited minor variation among marine animals, potentially because the carnitine pool maintains its dynamic balance. Additionally, significant correlations were observed between the CAR content and environmental factors in some species: a negative correlation with seawater temperature and positive correlations with latitude, seawater salinity, and depth. These results suggest that the CAR content in marine animals is influenced by environmental changes. This study provides theoretical insights for understanding the characteristics and influencing factors of CAR content in marine animals.展开更多

Unfortunately, unprotected ARG will be degraded in the rumen and its price is high, thus feeding rumen-protected ARG seems to be uneconomical. Alternatively, N-carbamoyl glutamate （NCG） is structural analogue of N-acetyl glutamate, cofactor of cabamoyl phosphate synthetasel, is lower in rumen degradation compared to ARG. Additionally, rumen epithelial and duodenal cells have potentially utilized the NCG for ureagenesis. Supplementation of NCG to high yielding dairy cows increased plasma concentration of ARG and nitric oxide, decreased the plasma ammonia N and improved lactation performance and N utilization. Supplementation of NCG enhanced pregnancy rates in rats, improved litter size and fetal survival rate, thereby improved the reproductive performance of sows. Oral NCG supplementation increases plasma ARG and somatotropin levels, and increased growth rate and muscle protein synthesis in nursing piglets. The NCG is potential a relatively cheaper source of feed additive to offer vital compensation over oral administration of ARG, resulting in improved ruminant animal health and production. In this article, we reviewed the mechanism of AfiG biosynthesis by NCG and their significance in growth, reproduction, milk production and N utilization in ruminant animals.展开更多

Additionally, significant correlations were observed between the CAR content and environmental factors in some species: a negative correlation with seawater temperature and positive correlations with latitude, seawater salinity, and depth. These results suggest that the CAR content in marine animals is influenced by environmental changes. This study provides theoretical insights for understanding the characteristics and influencing factors of CAR content in marine animals.
文摘Studying the interactions and relationships between humans and animals is known as ethnozoology.Indigenous medicine that is used to prevent,diagnose,and cure physical and mental disorders is known as traditional medicine.The understanding of how various animal materials are used in conventional medicine by different ethnic communities is undocumented and largely passed through oral communication from generation to generation.Traditional medicine is the primary source of healthcare for many ethnic tribes in Ethiopia.Approximately 80%of Ethiopians rely on traditional medicine to cure a variety of human conditions.However,because they are passed down orally from generation to generation,this indigenous medical practice is being disregarded and is still disappearing as a result of inadequate documentation.Ethiopia is a land of diversity,with a wide variety of fauna and ethnic groups,each of whom uses and manipulates medicinal animals in a unique way to treat a range of human illnesses.The main participants in the curative component of traditional medicine practice are traditional healers,who go by various names in different regions of the nation.In Ethiopia,though indigenous societies medicinally used animal species for millennia,they have given little attention to their conservation.Therefore,documentation of traditional medicinal animals and indigenous healing practices of Ethiopian cultures are very important to preserve the country’s resources.
文摘In November 2024,the famous British zoologist Jane Goodall,known as“the Mother of Chimpanzees”,visited China for the 17th time.During her trip,she celebrated the 30th anniversary of her“Roots&Shoots”project in China and participated in the 8th“It's Warm Winter”event organized by the Beijing It's Animal Protection Public Welfare Foundation(It's Fund).

文摘Arginine （ARG） exerts many beneficial effects on animal body and enhanced angiogenesis, lactogenesis, which finally leads to the improvement in nitrogen （N） metabolism, reproduction, lactation, immunity and growth. Unfortunately, unprotected ARG will be degraded in the rumen and its price is high, thus feeding rumen-protected ARG seems to be uneconomical. Alternatively, N-carbamoyl glutamate （NCG） is structural analogue of N-acetyl glutamate, cofactor of cabamoyl phosphate synthetasel, is lower in rumen degradation compared to ARG. Additionally, rumen epithelial and duodenal cells have potentially utilized the NCG for ureagenesis. Supplementation of NCG to high yielding dairy cows increased plasma concentration of ARG and nitric oxide, decreased the plasma ammonia N and improved lactation performance and N utilization. Supplementation of NCG enhanced pregnancy rates in rats, improved litter size and fetal survival rate, thereby improved the reproductive performance of sows. Oral NCG supplementation increases plasma ARG and somatotropin levels, and increased growth rate and muscle protein synthesis in nursing piglets. The NCG is potential a relatively cheaper source of feed additive to offer vital compensation over oral administration of ARG, resulting in improved ruminant animal health and production. In this article, we reviewed the mechanism of AfiG biosynthesis by NCG and their significance in growth, reproduction, milk production and N utilization in ruminant animals.

文摘Selenium is an essential trace mineral important for the maintenance of homeostasis in animals and humans.It evinces a strong antioxidant,anti-inflammatory and potential antimicrobial capacity.Selenium biological function is primarily achieved by its presence in selenoproteins as a form of selenocysteine.Selenium deficiency may result in an array of health disorders,affecting many organs and systems;to prevent this,dietary supplementation,mainly in the forms of organic(i.e.,selenomethionine and selenocysteine)inorganic(i.e.,selenate and selenite)sources is used.In pigs as well as other food animals,dietary selenium supplementation has been used for improving growth performance,immune function,and meat quality.A substantial body of knowledge demonstrates that dietary selenium supplementation is positively associated with overall animal health especially due to its immunomodulatory activity and protection from oxidative damage.Selenium also possesses potential antiviral activity and this is achieved by protecting immune cells against oxidative damage and decreasing viral replication.In this review we endeavor to combine established and novel knowledge on the beneficial effects of dietary selenium supplementation,its antioxidant and immunomodulatory actions,and the putative antimicrobial effect thereof.Furthermore,our review demonstrates the gaps in knowledge pertaining to the use of selenium as an antiviral,underscoring the need for further in vivo and in vitro studies,particularly in pigs.
