Benign Prostate Hyperplasia
This entry presents B-mode and color Doppler imaging of the prostate and testes in dogs suffering from benign prostate hyperplasia (BPH), and receiving Deslorelin Acetate (SuprelorinTM) or Osaterone Acetate (YpozaneTM). The study was planned as a controlled clinical trial, dogs were divided into negative control (healthy dogs, n = 10), positive control (dogs with BPH, n = 10), and study groups, III (n = 15), receiving deslorelin acetate (DA), and IV (n = 10), receiving osaterone acetate (OA). The B-mode appearance of the prostate parenchyma improved in all investigated dogs from the DA group, and in 60% of OA dogs.

Bimodal Processing and Learning in Insect Models
The study of sensory systems in insects has a long-spanning history of almost an entire century. Olfaction, vision, and gustation are thoroughly researched in several robust insect models and new discoveries are made every day on the more elusive thermo- and mechano-sensory systems. Few specialized senses such as hygro- and magneto-reception are also identified in some insects. In light of recent advancements in the scientific investigation of insect behavior, it is not only important to study sensory modalities individually, but also as a combination of multimodal inputs. This is of particular significance, as a combinatorial approach to study sensory behaviors mimics the real-time environment of an insect with a wide spectrum of information available to it. As a fascinating field that is recently gaining new insight, multimodal integration in insects serves as a fundamental basis to understand complex insect behaviors including, but not limited to navigation, foraging, learning, and memory.

Biological Medicinal Products
Definitions of biological medicinal products (BMPs) vary depending on the source. BMPs are manufactured using complex biological/biotechnological processes involving living cell lines, tissues and organisms such as microorganisms, plants, humans and even animals.

Bird Survival in the City
Urbanization poses a significant threat to biodiversity worldwide. Yet, a few wild species of flora and fauna thrive in urban landscapes by undergoing certain trait adaptations. Birds are a well-studied taxon in terms of urbanization-induced trait changes. Some robust findings on ecological traits, life history, physiology, behavior, and genetic traits changes in individual species as well as bird communities have been observed. Urbanized birds differ in behavioral traits, showing an increase in song frequency and amplitude, and bolder behavior, compared to rural populations of the same species. Differential food resources and predatory pressure results in changes in life-history traits including prolonged breeding duration, and increases in clutch and brood size to compensate for lower survival. Other species-specific changes include changes in hormonal state, body state, and genetic differences from rural populations. There is a paucity of studies in tropical cities and a need for greater examination of traits that influence persistence and success in native vs. introduced populations.

Black Rhinoceros
Black rhinoceros under human care are predisposed to Iron Overload Disorder that is unlike the hereditary condition seen in humans. We aim to address the black rhino caretaker community at multiple perspectives (keeper, curator, veterinarian, nutritionist, veterinary technician, and researcher) to describe approaches to Iron Overload Disorder in black rhinos and share learnings. This report includes sections on (1) background on how iron functions in comparative species and how Iron Overload Disorder appears to work in black rhinos, (2) practical recommendations for known diagnostics, (3) a brief review of current investigations on inflammatory and other potential biomarkers, (4) nutrition knowledge and advice as prevention, and (5) an overview of treatment options including information on chelation and details on performing large volume voluntary phlebotomy. The aim is to use evidence to support the successful management of this disorder to ensure optimal animal health, welfare, and longevity for a sustainable black rhinoceros population.

Calcium Propionate in Dairy Cows
Calcium propionate is a safe and reliable food and feed additive. It can be metabolized and absorbed by humans and animals as a precursor for glucose synthesis. In addition, calcium propionate provides essential calcium to mammals. In the perinatal period of dairy cows, many cows cannot adjust to the tremendous metabolic, endocrine, and physiological changes, resulting in ketosis and fatty liver due to a negative energy balance (NEB) or milk fever induced by hypocalcemia. On hot weather days, cow feed (TMR or silage) is susceptible to mildew, which produces mycotoxins. These two issues are closely related to dairy health and performance. Propionic acid is the primary gluconeogenic precursor in dairy cows and one of the safest mold inhibitors. Therefore, calcium propionate, which can be hydrolyzed into propionic acid and Ca2+ in the rumen, may be a good feed additive for alleviating NEB and milk fever in the perinatal period of dairy cows. It can also be used to inhibit TMR or silage deterioration in hot weather and regulate rumen development in calves. This paper reviews the application of calcium propionate in dairy cows.

Calcium-Responsive Nanoparticles for Animal Systems
Since the 1970s, the emergence and expansion of novel methods for calcium ion (Ca2+) detection have found diverse applications in vitro and in vivo across a series of model animal systems. Matched with advances in fluorescence imaging techniques, the improvements in the functional range and stability of various calcium indicators have significantly enhanced more accurate study of intracellular Ca2+ dynamics and its effects on cell signaling, growth, differentiation, and regulation. Nonetheless, the current limitations broadly presented by organic calcium dyes, genetically encoded calcium indicators, and calcium-responsive nanoparticles suggest a potential path toward more rapid optimization by taking advantage of a synthetic biology approach.

Camel husbandry
Minor species such as camels are lacking for transactional agreements between applied research and regulatory agencies in regards of animal welfare. Given these species being progressively recognized as sustainable livestock even under extreme environmental conditions, camel international science has brought about valuable academic efforts towards its functional revalorization but not updated policy reforms. By means of bibliometrics analysis, camel science upturn and its academic and societal impacts were evaluated to highlight the potential promoting factors for camel research advances and specific parallel law enforcing. Historical camel referring documents that were indexed in ScienceDirect directory from 1880-2019 were considered. Camel as a species did not affect research impact (p > 0.05) despite the journal, author number, corresponding author origin, discipline and publication year affecting it (p < 0.001). However, camel welfare-related laws remain scarcely available. In this framework, research advances must play a cardinal role in influencing business stakeholders and animal welfare advocacies to promote sustainable camel husbandry practices through science-based law enforcement in this emerging industry on a global scale.

Canine Heat-Related Illness
Heat-related illness - more commonly known as "heat stroke" - is a potentially fatal disorder that can affect both man and animals. The condition has two main causes: exertional and environmental heat. Exertional heat-related illness occurs either when a dog is active in a hot environment, or associated with strenuous and typically prolonged activity in any temperature. Environmental heat-related illness occurs when the ambient temperature and humidity increase beyond the dog's cooling limits, cases of environmental heat-related illness typically occur during heatwave events.
