Estimating the impact of sarcoptic mange epidemic on the population size of wild raccoon dogs () from wildlife rescue data.

The impact of infectious diseases on host populations is often not quantified because it is difficult to observe the host population and infectious disease dynamics. To address this problem, we developed a state-space model to simultaneously estimate host population and disease dynamics using wildlife rescue data. Using this model, we aimed to quantify the impact of sarcoptic mange on a Japanese raccoon dog population by estimating the change in their relative population size.

Dapagliflozin administration to a mouse model of type 2 diabetes induces DNA methylation and gene expression changes in pancreatic islets.

Decreased pancreatic β-cell volume is a serious problem in patients with type 2 diabetes mellitus, and there is a need to establish appropriate treatments. Increasingly, sodium/glucose cotransporter 2 (SGLT2) inhibitors, which have a protective effect on pancreatic β-cells, are being prescribed to treat diabetes; however, the underlying mechanism is not well understood. We previously administered SGLT2 inhibitor dapagliflozin to a mouse model of type 2 diabetes and found significant changes in gene expression in the early-treated group, which led us to hypothesize that epigenetic regulation was a possible mechanism of these changes.

Exploring the Potential of CarbonCool® in Rapid Prehospital Cooling for Severe Heat Stroke.

Objective: Heat stroke is a life-threatening condition that is characterized by body temperatures above 40 °C and central nervous system dysfunction. Immediate cooling is imperative to prevent irreversible cellular damage and improve patient outcomes. Here, we report two cases of heat stroke that highlight the use of a novel cooling suit (CarbonCool®) as a rapid cooling intervention administered in the prehospital setting, primarily focusing on patients with classic heat stroke.

Association between fall-related serious injury and activity during fall in an acute care hospital.

Objectives: Few studies have evaluated the mechanism of serious injury in acute hospitalization. Thus, the association between fall-related serious injury and activity during falls in acute care hospital remains unclear. Herein, we investigated the relationship between serious injury caused by fall and activity at the time of the fall in an acute care hospital.

Antimicrobial resistance in isolates from Japanese raccoon dogs () in Kanagawa Prefecture, Japan: Emergence of extended-spectrum cephalosporin-resistant human-related clones.

Wild animals are one of the putative reservoirs of antimicrobial-resistant bacteria, but the significance of raccoon dogs remains to be investigated. Raccoon dogs can be a reservoir of antimicrobial-resistant bacteria. This study aimed to explore the prevalence of antimicrobial resistance, mainly extended-spectrum cephalosporins resistance, in isolates from faeces of 80 Japanese raccoon dogs in Kanagawa Prefecture, Japan.

Analysis of thyroid function in Japanese patients with coronavirus disease 2019.

Thyroid dysfunction that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is becoming increasingly recognized. However, only a few reports in Japan have addressed this issue to date. In this study, we sought to clarify whether infection with SARS-CoV-2 affected thyroid hormone levels and whether these hormones could be better predictors of prognosis in patients with coronavirus disease 2019 (COVID-19).

Development of a rapid scabies immunodiagnostic assay based on transcriptomic analysis of Sarcoptes scabiei var. nyctereutis.

Scabies is a highly contagious skin disease caused by the mite Sarcoptes scabiei that affects many mammals. However, the sensitivity of traditional tests for scabies diagnosis in humans is less than 50%. To simplify the diagnosis of scabies, methods that are simple, sensitive, specific, and cost-effective are required.

Captive environmental change and induction of natural breeding and egg-laying in ploughshare tortoises (Astrochelys yniphora).

The ploughshare tortoise (Astrochelys yniphora) is an endangered species. It is important to increase the number of tortoises in the wild and captivity; however, breeding in captivity, especially outside of the natural habitat area, has been unsuccessful worldwide. As a result of an emergency rescue due to a violation of the Act of Conservation of Endangered Species of Wild Fauna and Flora, Nogeyama Zoological Gardens (Yokohama, Japan) has housed ploughshare tortoises, and a natural breeding trial started in 2011.

Multilobular tumor of bone on the forehead of a guinea pig.

Multilobular tumor of bone (MLTB) is an infrequent, slow-growing, bone neoplasm formed predominantly on the head. These tumors can behave as malignant neoplasms clinically and pathologically and can metastasize occasionally. No cases of MLTB in rodents have been reported, to our knowledge.

Emotion estimation using a wearable heart rate monitoring device in Asian elephants (Elephas maximus) during veterinary clinical procedures.

Fatal accidents in captive elephants occasionally occur because humans are unable to gauge elephants' emotions solely by their behavior. The intellectual capacity of elephants makes them capable of understanding circumstantial changes and associated emotions, allowing them to react accordingly. Physiological markers, such as heart rate variability, may be effective in determining an elephant's emotional state.

Possible transmission of Sarcoptes scabiei between herbivorous Japanese serows and omnivorous Caniformia in Japan: a cryptic transmission and persistence?

Background: Two transmission patterns of Sarcoptes scabiei in host mammal communities have been reported based on microsatellite-level genetic studies in the last two decades. While one involves restrictions among different host taxa, the other is associated with predator-prey interactions between different host taxa. In contrast to these observations, the present study reports a possible irregular case of transmission of S.

Novel treatment for chronic pododermatitis in an Indian elephant (Elephas maximus indicus) with Mohs' paste.

Asian and African elephants are frequently afflicted by foot disorders that can be very challenging to manage even with aggressive therapy. Such conditions may have indirect life-threatening effects. Mohs' paste (zinc chloride based escharotic agent) was used to treat a female Indian elephant (Elephas maximus indicus) aged 39 years with foot disorder at Kanazawa Zoological Gardens.

The complete mitochondrial genome of Sarcoptes scabiei var. nyctereutis from the Japanese raccoon dog: Prediction and detection of two transfer RNAs (tRNA-A and tRNA-Y).

Evaluation of somatotype in the reticulated giraffe (Giraffa camelopardalis reticulata) using three-dimensional laser measurement.

The giraffe (Giraffa camelopardalis) is a difficult animal to keep in captivity as it has high mortality due to nutrition-related disorders, perhaps because the giraffe's condition is difficult to evaluate. Image analysis techniques have recently become popular and may be useful for evaluating the giraffe's somatotype. The present study aimed to evaluate the giraffe somatotype using a three-dimensional laser measurement device, and to examine the usefulness of this method.

Long-term outcomes of patients evacuated from hospitals near the Fukushima Daiichi nuclear power plant after the Great East Japan Earthquake.

Introduction: After the accident of the Fukushima Daiichi nuclear power plant due to the Great East Japan Earthquake in March 2011, the Japanese government issued a mandatory evacuation order for people living within a 20 km radius of the nuclear power plant. The aim of the current study was to investigate long-term outcomes of these patients and identify factors related to mortality.

Materials And Methods: Patients who were evacuated from hospitals near the Fukushima Daiichi nuclear power plant to the Aizu Chuo Hospital from 15 to 26 March, 2011 were included in this study.

Factors affecting the occurrence of enteritis in 10- to 12-month-old eastern grey kangaroos (Macropus giganteus).

Eastern grey kangaroos (Macropus giganteus) younger than 19 months at Kanazawa Zoological Gardens, Japan, frequently died of enteritis. The main cause of death was coccidiosis. This study aimed to reveal retrospectively the clinical features of enteritis and factors contributing to its high occurrence.

Molar eruption and identification of the eastern grey kangaroo (Macropus giganteus) at different ages.

To treat dental disorders and estimate age, it is important that veterinarians understand teeth eruption sequence for the animal in question. Few dental images of the eastern grey kangaroo have been published. In the present study, radiographic imagings of 29 kangaroos, ranging in age from 12 months to 10 years 9 months, was used to surveil the replacement of premolars and the eruption of molars.

New techniques to collect live Sarcoptes scabiei and evaluation of methods as alternative diagnostics for infection.

Sarcoptes scabiei is a widespread, highly contagious skin disease that affects many mammals including humans. The biological characteristics of S. scabiei remain unclear.

Supplemental feeding of captive neonatal koalas (Phascolarctos cinereus).

Koalas (Phascolarctos cinereus) are cautious animals, making supplemental feeding of neonates challenging because of disturbances to the normal routine. However, supplemental feeding is beneficial in improving juvenile nutrition using less formula than required for hand-rearing, and allowing maternal bonding to continue through suckling. In this study, two neonatal koalas, delivered by the same mother in 2 years, exhibited insufficient growth post-emergence from the pouch; supplemental feeding was therefore initiated.

Hematological and pathological features of massive hepatic necrosis in two radiated tortoises (Astrochelys radiata).

Two radiated tortoises (Astrochelys radiata) exhibited anorexia and hypokinesia. In both cases, hematological and serum biochemical examinations revealed high alkaline phosphatase levels, moderately high aspartate aminotransferase levels and white blood cell counts approximately within the normal range. Despite being treated, the tortoises died 9 and 43 days after the first clinical examination.

FOLLICULAR CELL CARCINOMA OF THE THYROID GLAND IN THREE CAPTIVE AGED RACCOON DOGS (NYCTEREUTES PROCYONOIDES).

The clinical and histologic features of thyroid carcinoma in raccoon dogs have not been previously reported. Three of four raccoon dogs (Nyctereutes procyonoides) over 8 yr of age at the Nogeyama Zoological Gardens developed thyroid follicular cell carcinomas that were detected at necropsy. The affected raccoon dogs were rescued from the wild and were housed at the Nogeyama Zoological Gardens for 8 yr 8 mo, 8 yr 10 mo, and 10 yr 3 mo, respectively.
