This implies that current risk assessment practices are neglecting an important aspect of toxicity, such as delayed effects across generations due to a time gap between chemical exposure and emergence of effects.Brucellosis caused by Brucella abortus and Brucella melitensis is endemic in the Republic of Azerbaijan but a complex mix of fiscal, political and technical constraints has impeded regulatory authority decision making for adoption of a sustainable national control programme. This paper reports a series of epidemiologic studies of the disease in animals and humans which we conducted between 2009 and 2020. A preliminary study and a subsequent larger study using vaccination of all non-pregnant female sheep and goats of breeding age and all females between 3 and 8 months with conjunctival Rev1 vaccine both recorded significant reduction in small ruminant seroprevalences. A case control study of winter pasture flocks found many case and control farmers used raw milk to make dairy products for sale, ate fresh cheese and sold dairy products in unregulated markets. Almost all farmers expressed willingness to pay a portion of the costs associated with elimination of brucellosis from their flocks. A pilot human study in 2009 led to a large study in 2017 which recorded an overall seroprevalence of 8.1% in humans. Persons in farm related occupations were at greater risk than urban persons and males were more likely to be seropositive than females. Risk factors included keeping small ruminants, using raw milk cheese and slaughtering animals whereas having heard education information about brucellosis and vaccinating against brucellosis were protective.The development and early morphological features of feline hip osteoarthritis (OA) are largely unknown. Tears in the acetabular labrum and at the chondrolabral transition zone are suggested to be important in the pathogenesis of human hip OA, but in cats such lesions have not been described. We investigated associations between computed tomography (CT)-detected joint changes and microscopic articular cartilage lesions, the distribution of detected changes, and histologically evaluated the acetabular margin (AM) in hip joints from 20 cats. Histologic evaluation was undertaken on at least one joint from each cat. CT-detected joint changes and articular cartilage lesions were graded and the histological appearance of CT-detected osteophytes evaluated. The majority of CT-detected lesions and cartilage lesions were mild. click here Whole-joint CT scores and AM osteophyte CT scores showed moderate to strong correlation with cartilage scores. The odds were higher for presence of CT-detected osteophytes in craniodorsal, cranial, cranioventral, ventral and dorsal AM regions. Peripheral acetabular regions showed higher cartilage lesion grades than central regions. Tears, seen as fissures/clefts, in labral and perilabral tissues were common. CT-detected AM osteophytes morphologically presented as pointed sclerotic bone, spur-shaped bone or rounded chondro-osteophytes. The results suggest that CT is a valuable tool for diagnosing early feline hip OA. CT-detected osteophytes showed variable histologic morphologies, which may implicate different disease mechanisms and/or disease stages. Tears in the AM could represent an early event in feline hip OA and this warrants further investigation.Osteoarthritis is treated with COX or fosfolipase A2 inhibitors such as carprofen, a propionic acid NSAID. The enhancement of its action over the articular cartilage is mandatory to facilitate its therapeutic application. Drug uptake into the cartilage requires high synovial fluid concentrations, anticipating its rapid distribution towards bloodstream. Thus, intraarticular administration improves local targeting of the drug, lining with the site of action. A pharmacokinetic study in rabbits has been performed to evaluate carprofen nanoparticles after intraarticular administration. Pharmacokinetic analysis of plasma profiles through a modelling approach, has demonstrated the rapid distribution of drug outside of synovial chamber but mainly remaining in plasma. The data modelling has demonstrated the existence of two release-absorption processes when the nanoparticles are administered in the synovial space. Additionally, results are predictive of the PK profile of some other species such as cat, dogs or humans.Analysing hair cortisol concentrations (HCCs) is a minimally invasive way to retrospectively assess long-term stress, and its application in studies of animal welfare and stress has attracted considerable interest. However, not only stress-related effects but also hair-specific characteristics and external influences can affect HCCs and interfere with the interpretation of results. Thus, it was the aim of this study to investigate the impact of daylight and UV irradiation on cortisol concentrations in the hairs of pigs and cattle. We also examined whether a potential irradiation effect on HCCs depended on the colour of the hair. For this purpose, black and white hair samples from 18 Saddleback pigs and 18 Holstein Friesian cattle were exposed to artificial light (both visible and UV) and compared with control hair samples from the same animals kept in the dark. Exposure to artificial light significantly decreased HCCs in both pigs (P less then 0.05) and cattle (P less then 0.001), and hair colour had an imal conditions, such as outdoor and indoor housing.It remains unknown whether dairy cows with more reactive temperament produce more enteric methane (CH4) and are less bioenergetically efficient than the calmer ones. The objectives of this study were (a) to evaluate the relationship between cattle temperament assessed by traditionally used tests with energetic metabolism and enteric CH4 emissions by crossbred dairy cows; (b) to assess how cows’ restlessness in respiration chambers affects energetic metabolism and enteric CH4 emissions. Temperament indicators were evaluated for 28 primiparous F1 Holstein-Gyr cows tested singly in the handling corral (entrance time, crush score, flight speed, and flight distance) and during milking (steps, kicks, defecation, rumination, and kick the milking cluster off). Cows’ behaviors within respiration chambers were also recorded for each individual kept singly. Digestibility and calorimetry trials were performed to obtain energy partitioning and CH4 measures. Cows with more reactive temperament in milking (the ones that kicked the milking cluster off more frequently) spent 25.
