mTORC2 ‐AKT‐LAT1 Signalling Participates in Methionine‐induced β‐CASEIN Expression in Mammary Epithelial Cells of Dairy Cows
This study investigated the role of the mammalian target of rapamycin complex 2 (mTORC2)-protein kinase B (AKT) signalling in methionine (Met)-induced L-type amino acid transporter 1 (LAT1) expression and milk protein production. Primary mammary epithelial cells (MECs) from mammary parenchymal tissues of 3 lactating cows and MAC-T bovine MECs were cultured with or without 0.6 mM Met. Rapamycin-insensitive companion of mTOR (RICTOR) siRNA, the mTORC1 inhibitor rapamycin and the AKT activator SC79 were used to evaluate the effects of mTORC2-AKT signalling on Met-induced LAT1 expression and function. Each experiment was perfo...

Dermatologic Aspects of Zoo Mammal Medicine
The article deals with the primary aspects of how to maintain healthy integument in zoo mammals and in particular why husbandry-related health problems can occur in general in a zoologic setting. While working with these species we are often faced with diagnostic challenges, which may include a general approach (often requiring anesthesia or medical training), lack of “normal” references, and difficulties, especially if the cutaneous signs are not a primary ailment, but a manifestation of a generalized disease (eg, immune-suppression). The different etiologies of skin problems are discussed with clinical examples. (Sou...

(Exotic Animal) Dermatology
Due to the increase in popularity of exotic animals as pets in households as well as their recognized importance on the entire ecosystem, zoologic medicine has made significant advances in the past decades. Consequently, all areas of this field have developed considerably. Dermatologic disorders are some of the most common problems affecting companion animals (eg, dogs, cats, horses), and exotic animals are not the exception. This issue of the Veterinary Clinics of North America: Exotic Animal Practice brings, in separate articles, up-to-date information on bird, rabbit, ferret, rodent, reptile, amphibian, four-toed hedgeh...

Rickettsia conorii Subspecies israelensis in Captive Baboons
Emerg Infect Dis. 2023 Apr;29(4):841-843. doi: 10.3201/eid2904.221176.ABSTRACTHamadryas baboons (Papio hamadryas) may transmit zoonotic vector-borne pathogens to visitors and workers frequenting zoological parks. We molecularly screened 33 baboons for vector-borne pathogens. Three (9.1%) of 33 animals tested positive for Rickettsia conorii subspecies israelensis. Clinicians should be aware of potential health risks from spatial overlapping between baboons and humans.PMID:36958035 | DOI:10.3201/eid2904.221176 (Source: Emerging Infectious Diseases)

Antioxidant additive melatonin in tris-based egg yolk extender improves post-thaw sperm attributes in Hariana bull
Anim Reprod Sci. 2023 Mar 15;251:107214. doi: 10.1016/j.anireprosci.2023.107214. Online ahead of print.ABSTRACTIn the study, melatonin, a known antioxidant pineal peptide was used as an additive in the tris-egg yolk glycerol-based semen extender in Hariana bull semen and post-thaw sperm characters were evaluated. In the study, Group I was a control without melatonin; and Group II, III, and IV were having 0.5 mM, 1 mM, and 2 mM melatonin/80 × 106 spermatozoa, respectively were treatment groups. Thirty-two semen ejaculates from 4 Hariana bulls were processed for freezing and post-thaw sperm characteristics were evaluated. S...

Bacterial Cholecystitis and Cholangiohepatitis in Common Marmosets ( < em > Callithrix jacchus < /em > )
Comp Med. 2023 Mar 21. doi: 10.30802/AALAS-CM-22-000075. Online ahead of print.ABSTRACTThe common marmoset (Callithrix jacchus), a New World NHP, has emerged as important animal model in multiple areas of translational biomedical research. The quality of translational research in marmosets depends on early diagnosis, treatment, and prevention of their spontaneous diseases. Here, we characterize an outbreak of infectious cholangiohepatitis that affected 7 adult common marmosets in a single building over a 10-mo period. Marmosets presented for acute onset of lethargy, dull mentation, weight loss, dehydration, hyporexia, and ...
