Seasonal Dynamics of Ticks and Tick-Borne Pathogens in Republic of Korea.

Tick-borne diseases are a public health problem and a significant burden on the livestock industry. The seasonal abundance of ticks and tick-borne pathogens strongly correlates with the prevalence of these diseases. To investigate the seasonal variation in ticks and tick-borne pathogens, ticks were collected from Gangwon State, Korea, and the tick-borne pathogens , , , and were examined.

Suspected paroxysmal dyskinesia in four small-breed dogs: Clinical presentation, diagnosis, management and prognosis.

This case report details the clinical presentation, diagnosis, management and prognosis of paroxysmal dyskinesia (PD) in four small-breed dogs, each weighing under 6 kg: A 7-year-old spayed female Pomeranian, an 8-year-old female mixed breed, a 1-year-old female Pomeranian and a 9-year-old castrated male Poodle. These dogs were referred to our hospital due to movement disorders. Diagnosis was facilitated by video recordings of the episodes, assessing motor activity, consciousness, episode duration, any pre- or post-episodic behaviour as well as the presence of autonomic signs.

Comparison of the fecal microbiota with high- and low performance race horses.

Exercise plays an important role in regulating energy homeostasis, which affects the diversity of the intestinal microbial community in humans and animals. To the best of the authors' knowledge, few studies have reported the associations between horse gut microbiota along with their predicted metabolic activities and the athletic ability of Jeju horses and Thoroughbreds living in Korea. This study was conducted to investigate the association between the gut microbiota and athletic performance in horses.

Utility of ultra-rapid real-time PCR for detection and prevalence of Rickettsia spp. in ticks.

Background: Rickettsia spp. are important tick-borne pathogens that cause various human and animal diseases worldwide. A tool for rapid and accurate detection of the pathogens from its vectors is necessary for prevention of Rickettsioses propagation in humans and animals, which are infested by ticks.

Real-time PCR biochip for on-site detection of Coxiella burnetii in ticks.

Background: Q fever, a zoonosis caused by Coxiella burnetii, has adverse effects on public health. Ticks are vectors of C. burnetii and they contribute to the transmission of the pathogen.

Novel variants of the newly emerged Anaplasma capra from Korean water deer (Hydropotes inermis argyropus) in South Korea.

Background: Anaplasma spp. are tick-borne Gram-negative obligate intracellular bacteria that infect humans and a wide range of animals. Anaplasma capra has emerged as a human pathogen; however, little is known about the occurrence and genetic identity of this agent in wildlife.

Clusterin is highly expressed in tubular complexes during spontaneous pancreatitis of spontaneous hypertensive rats.

Pancreatitis is an inflammatory disorder of pancreas which leads to varying degrees of pancreatic endocrine and exocrine dysfunction and manifests in either acute or chronic forms. Spontaneous pancreatitis in experimental animals has rarely been reported. Here, we found acute to chronic courses of spontaneous pancreatitis in spontaneously hypertensive rats (SHRs), showing the formation of tubular complexes (TCs) and enhanced islet regeneration.

Influence of Horse and Rider on Stress during Horse-riding Lesson Program.

The present study aims to confirm the influence of a horse-riding lesson program (HRLP) on the stress level of horses and riders by respectively analyzing their salivary cortisol concentration. Twenty-four healthy horses and 23 riders participated in this study. The horses were randomly classified into two groups for the horse riding lesson program: Class 1 (for the beginner lesson) and Class 2 (for the intermediate lesson).

New record of Lipoptena fortisetosa (Diptera: Hippoboscidae) collected from Siberian roe deer on Jeju Island, Korea.

Lipoptena deer keds (Diptera: Hippoboscidae) are blood-sucking ectoparasites of mammals, and only one species, Lipoptena cervi (L.), has previously been reported from the Republic of Korea. A study of Siberian roe deer Capreolus pygargus Pallas on Jeju Island, south of the Korean mainland, led to the discovery of a second species of deer ked, Lipoptena fortisetosa Maa, for Korea.

Ticks collected from migratory birds, including a new record of Haemaphysalis formosensis, on Jeju Island, Korea.

Migratory birds may disperse parasites across ecological barriers, and recent climate change may alter the pattern of ectoparasite dispersal via changed patterns of bird migration. In order to document the parasitization of migratory birds by Ixodidae ticks on Jeju Island in Korea, we examined 934 migratory birds comprising 75 species for ticks from 2010 to 2012. In total, 313 ticks were collected from 74 migratory birds across 17 avian species and identified based on morphological keys.

Evaluation of a new method for pulse push/pull hemodialysis: comparison with conventional hemodialysis.

The repetition of forward and backward filtration during hemodialysis (HD) increases convective mass transfer, and thus, the authors devised a method of achieving cyclic repletion of ultrafiltration and backfiltration. Hemodialytic efficiencies of the developed unit are described. The devised method, named pulse push/pull hemodialysis (PPPHD), is based on the utilization of dual pulsation in a dialysate stream.

Physiological changes in jeju crossbred riding horses by swim training.

The changes in physiologic parameters by swim exercise duration were examined in five female well-trained Jeju crossbred riding horses that had riding experience of more than three years without swim training experience. The horses were performed with swim exercise for 10 min (60.0 m/min) once a day for 14 days.

Real time observation of mouse fetal skeleton using a high resolution X-ray synchrotron.

The X-ray synchrotron is quite different from conventional radiation sources. This technique may expand the capabilities of conventional radiology and be applied in novel manners for special cases. To evaluate the usefulness of X-ray synchrotron radiation systems for real time observations, mouse fetal skeleton development was monitored with a high resolution X-ray synchrotron.

G-, R- and C-band patterns of goral (Nemorhaedus caudatus) and comparison to goat (Capra hircus).

The karyotype of goral (Nemorhaedus caudatus, 2n = 56) was prepared using lymphocytes and its chromosomal band patterns were compared with those of goat (Capra hircus, 2n = 60) by CBG-, GTG- and RBG-banding techniques. The standard karyotype of goral was composed of 54 acrocentric autosomes, submetacentric X chromosome, and acrocentric Y chromosome. C-bands were prominent in all autosomes except the X chromosome.

Antigenic diversity of Theileria major piroplasm surface protein gene in Jeju black cattle.

Piroplasms are tick-transmitted, intracellular, hemoprotozoan parasites that cause anorexia, fever, anemia, and icterus. Theileriosis is caused by Theileria sergenti and causes major economic losses in grazing cattle in Japan and Korea. In May 2003, we examined the antigenic diversity of the major piroplasm surface protein (MPSP) gene in 35 healthy Jeju black cattle that were born and raised at the National Institute of Subtropical Agriculture.

Computational dose predictions for combined treatment of hemofiltration with weekly hemodialysis.

Hemodialysis (HD) has sufficient efficacy as a conventional diffusive treatment for removing small molecules, whereas hemofiltration (HF), which is a convective treatment, has an improved the clearance of intermediate-sized molecules. This paper reports a combined treatment (CT) which combines the diffusive and convective efficacies of HF several times weekly with HD weekly. CT modalities with various schedules and prescriptions are described mathematically using a variable-volume two-compartment kinetics model, and the kinetic parameters were obtained from previous clinical reports and a hemodialysis-related database.

Genetic polymorphism of the serum proteins of horses in Jeju.

The study was carried out to investigate the genetic polymorphism of the serum proteins of horses in Cheju. They were assigned to three groups; 45 Cheju native horses(CNH), 60 Cheju racing horses(CRH) and 60 Thoroughbreds(TB). We analyzed the phenotypes and gene frequencies of serum proteins which were albumin (Alb), vitamin-D binding protein(GC), esterase (ES), A1B glycoprotein(A1B) and transferrin(TF) loci using horizontal polyacrylamide gel electrophoresis (HPAGE).
