[Purpose] The purpose of this study was to examine the effect of forward head posture on ankle joint range of motion and static balance. [Subjects] The study subjects were on 51 healthy undergraduates (22 males and 29 females) who had not experienced cervical or shoulder pains, or hospital diagnosis of musculoskeletal dysfunction in the previous four weeks. [Methods] The cranial vertical angle (CVA) was measured to investigate forward head posture, and the Tetrax Portable Multiple System (Tetrax Ltd, 56 Miryam Ramat Gan, Sunlight, Israil) was used to measure static balance using the stability test index (STI). Distal dualer-IQ (JTECH Medical, USA) was used to measure ankle joint range of motion. [Results] Cranial vertical angle had an influence on ankle joint plantarflexion, but no influence on static balance. [Conclusion] Forward head posture was shown to transmit tension to the ankle joint through the superficial back-line, one of the myofascial meridians connected to the fascia, which suggests that tension in the neck muscles influence the ankle joints.

A 12-year-old, 3.5-kg, intact female dog was presented with polyuria, polydipsia, and a pendulous abdomen. Laboratory examinations showed elevated hepatobiliary enzyme levels and neutrophilic leukocytosis. The adrenocorticotropic hormone stimulation test confirmed hyperadrenocorticism (HAC). Trilostane therapy managed the clinical condition and cortisol concentration. However, lymphocytosis and nonregenerative anemia developed after HAC remission. Bone marrow aspiration analysis revealed a lymphoproliferative disorder with a clonal T-cell population. Accordingly, the patient was diagnosed with T-cell chronic lymphocytic leukemia (CLL) and concurrent HAC. Thereafter, chemotherapy was initiated, which improved the lymphocytosis. However, euthanasia was performed because of worsening quality of life at 45 weeks after the first presentation. These results suggested that CLL could be masked by excessive endogenous cortisol and discovered after HAC remission.

A 10-month-old male Welsh Corgi with a history of acute blindness underwent neuro-ophthalmological testing and magnetic resonance imaging (MRI). Vision testing revealed complete visual deficits but the electroretinograph and pupillary light reflex were normal in both eyes. The motor and sensory functions of the eyelids and eyes were also normal. The MRI revealed compression of the optic chiasm caused by severe ventriculomegaly in the lateral and third ventricles. Such lesions are associated with inflammatory stenotic lesions in the mesencephalic aqueduct. Moderate neutrophilic pleocytosis was observed during cerebrospinal fluid analysis and Acinetobacter lwoffii was isolated, leading to a diagnosis of Acinetobacter-positive obstructive hydrocephalus. This is the first reported case of culture-proven Acinetobacter-associated postencephalitic hydrocephalus with acute blindness in a dog.

Recently, the adoption of the industrial Internet of things (IIoT) has optimized many industrial sectors and promoted industry “smartization.” Smart factories and smart industries connect the real and virtual worlds through cyber-physical systems (CPS). However, these linkages will increase the cyber security danger surface to new levels, putting millions of dollars' worth of assets at risk if communications in big network systems like IIoT settings are left unsecured. To solve these problems, the fundamental method is security, such as authentication and confidentiality, and it should require the encryption key. However, it is challenging the security performance with the limited performance of the sensor. Blockchain-based identity management is emerging for lightweight, integrity and persistence. However, the key generation and management issues of blockchain face the same security performance issues. First, through blockchain smart contracts and hierarchical deterministic (HD) wallets, hierarchical key derivation efficiently distributes and manages keys by line and group in the IIoT environment. Second, the pairing verification value based on an elliptic curve single point called Root Signature performs efficient public key certificate registration and verification and improves the key storage space. Third, the identity log recorded through the blockchain is the global transparency of the key lifecycle, providing system reliability from various security attacks. Keyless Signature Infrastructure (KSI) is adopted to perform efficiently via hash-based scheme (hash calendar, hash tree etc.). We analyze our framework compared to hash-based state commitment methods. Accordingly, our method achieves a calculation efficiency of O(nlog N) and a storage space saving of 60% compared to the existing schemes.

Triglyceride/high-density lipoprotein (HDL) cholesterol ratio (TG/HDL-C), triglyceride-glucose index (TyG), and non-HDL cholesterol level (non-HDL-C) have been proposed as surrogate markers for predicting metabolic syndrome (MetS). This study investigated whether these lipid-derived surrogate markers can predict MetS in Korean children and adolescents. Data from 1,814 participants were analyzed from the 2013-2016 Korean National Health and Nutrition Examination Survey. MetS was defined using three sets of criteria: Cook et al. (MetS1), de Ferranti et al. (MetS2), and the International Diabetes Federation (MetS3). The prevalence of MetS1, MetS2, and MetS3 was 4.6%, 11.3%, and 2.7%, respectively. In receiver operating characteristic curve analysis of MetS and lipid-derived surrogate markers, TG/HDL-C (0.937 for MetS1, 0.894 for MetS2, and 0.897 for MetS3) had the largest area under the curve (AUC), followed by TyG (0.906 for MetS1, 0.864 for MetS2, and 0.887 for MetS3), and non-HDL-C (0.752 for MetS1, 0.708 for MetS2, and 0.703 for MetS3) (all P < 0.001). The cutoff values for detecting MetS with TG/HDL-C, TyG, and non-HDL-C were 2.64, 8.52, and 111.6 for MetS1; 2.23, 8.47, and 110.7 for MetS2; and 2.64, 8.74, and 110.8 for MetS3, respectively. In conclusion, TG/HDL-C and TyG were similarly predictive of MetS. We propose using TG/HDL-C and TyG as surrogate markers for assessing MetS in Korean children and adolescents.

The objective of the present study was to analyze the activation and expression patterns of upstream and downstream factors of PGC-1α to determine whether antioxidant (AO) supplementation inhibits mitochondrial biogenesis in skeletal muscles as an adaptation to endurance training, as well as to analyze changes in endurance capacity based on such findings. For this objective, 24 male Sprague-Dawley (SD) rats were allocated into 4 groups (vehicle-sedentary, V-Sed; vehicle-exercise, V-EX; antioxidant-sedentary, AO-Sed; antioxidant-exercise, AO-EX) of 6 rats each. The rats were then treated with vitamin C (500 mgkg−1 body weightd−1) or a placebo for 8 wk, and a swimming program was implemented in some rats during the last 4 wk of this period. Immediately after the last training session, blood was collected from the tail of each rat, and TBARS was measured to test the effect of vitamin C as an AO. As a result, increased oxidative stress from exercise was inhibited by vitamin C supplementation. Analysis of whether reduced oxidative stress by vitamin C supplementation also inhibited mitochondrial biogenesis within skeletal muscles showed that phosphorylation of p38 MAPK and AMPK, along with levels of PGC-1α, NRF-1, mtTFA, and mitochondrial electron transport enzymes, increased after endurance training in spite of vitamin C supplementation. Moreover, running time, distance, and total work increased significantly in the exercise group as compared to those in the sedentary group, regardless of vitamin C supplementation. These results indicate that mitochondrial biogenesis and endurance capacity increase as a result of endurance training, regardless of AO supplementation.

A 10-year-old male castrated Maltese was referred with clinical signs of hematuria, stranguria, and pollakiuria. The dog was diagnosed with sterile hemorrhagic cystitis with urethroliths and cystoliths. To remove the uroliths, the dog underwent retrograde urohydropropulsion followed by a cystotomy. The following day, persistent bleeding in the urinary bladder was identified with large hematoma, hematuria and anemia. In order to reduce bleeding, the dog received 10 mg/kg of tranexamic acid (TXA) intravenously. Immediately after TXA administration, the dog developed anaphylactic shock manifested by hypotension, hypothermia, tachycardia and a dull mentation. Thus, an emergency treatment including bolus injection of crystalloid, administration of dexamethasone and diphenhydramine, and oxygen supplementation was given, after which the dog quickly recovered within a few minutes.

We investigated the neuritogenic effects of Tremella fuciformis (TF), which has been valued in traditional Chinese medicine as a remedy with nutritive and tonic actions, on PC12h cells. The cognitive improving effects of TF on scopolamine-induced (2 mg/kg, s.c.) amnesia in rats were also evaluated with using the Morris water maze task and by performing choline acetyltransferase (ChAT) immunohistochemistry. The water extract of TF (0.01—1 μg/ml) promoted neurite outgrowth of the PC12h cells in a dose dependent manner. TF was highly efficient at the concentration range of 0.1—1 μg/ml. Oral daily treatment with TF (100 or 400 mg/kg) for 14 consecutive days significantly reversed the scopolamine-induced deficit in learning and memory, and it alleviated decrease in cholinergic immunoreactivity induced by scopolamine in the medial septum and hippocampus. The results demonstrate that the promotion of neuritogenesis in neuronal culture cells by TF water extract is related with its activity for improving the performance of rats on a spatial learning and memory task. Moreover, the impairments of spatial learning and memory may be attributable to the decrease in activation of the septohippocampal cholinergic system and that TF ameliorated learning and memory deficits partly through its increasing the central cholinergic activity. Therefore, TF could represent a potentially useful agent that is able to improve the function of impaired cognitive processes.

An 8-year-old intact male Belgian Malinois, weighing 37.2 kg, was referred for evaluation due to right side facial paresis, ataxia and a two-month history of decreased cognitive ability. Physical and neurological examinations revealed mild depression, left-sided head tilt, right-sided facial paresis and ataxia. A well-demarcated, broad-based cerebellar mass and hyperostosis were found on CT imaging of the brain. Based on these CT findings, a cerebellar meningioma was strongly suspected. Hydroxyurea and prednisolone were administered; after 4 weeks, there was reduction in mass size as compared to initial CT results. However, the mass size was found to have grown 6 weeks after hydroxyurea treatment. We then prescribed a combination of imatinib mesylate and hydroxyurea. Two weeks following combination treatment, the mass size had reduced significantly. The mass continuously decreased in size until the patient died during anesthesia. Cerebellar transitional meningioma was confirmed by histopathologic examination. To the author’s knowledge, this is the first reported case of imatinib mesylate plus hydroxyurea therapy for the treatment of meningioma in veterinary medicine.

A 10-year-old intact male Shih Tzu dog presented with hematuria. Double-contrast cystography revealed a polypoid filling defect at the apex of the urinary bladder. Ultrasonography revealed a heterogeneously hypoechoic intramural mass with minimal vascular flow beneath the submucosal layer. After partial cystectomy, a well-demarcated bladder leiomyosarcoma was diagnosed on histopathology. The patient was alive and well without any clinical signs, recurrence, or metastasis at the 29-month follow-up after the surgical removal of the bladder mass. Leiomyosarcoma should be considered as a differential diagnosis if mass-like lesions are observed in the urinary bladder, although this type of malignancy is rare in canines. Histopathological confirmation is important for predicting prognosis and determining further medical plans.

Aims: In this study, we integrated two randomized control trials, PROSPECTIVE and IMPACT, to address the effect of probucol on cerebrocardiovascular events and carotid intima-media thickness (IMT) in Japanese, Korean, and Chinese patients with coronary artery disease (CAD). Methods: A total of 1,025 patients from the PROSPECTIVE and IMPACT studies were enrolled. The time to the first major adverse cerebrocardiovascular event, in addition to carotid IMT and lipid levels, was compared between the control and probucol groups. Results: In the integrated analysis, the adjusted hazard ratio (HR) and 95% confidence interval (CI) were 0.67 and 0.44–1.03, respectively, indicating a tendency to show the effect of probucol on cerebrocardiovascular events in secondary prevention. We also found no significant differences between the control and probucol groups in the mean IMT of the carotid arteries and its changes. However, we found a significant decrease in cerebrocardiovascular events in patients with reduced levels of HDL cholesterol (HDL-C) (≥ 6.25 mg/dL) compared with those with levels <6.25 mg/dL (p=0.024), without any increase in adverse events such as severe ventricular arrhythmias. Conclusion: We demonstrated a marginal effect of probucol on cerebrocardiovascular events in Asian patients with CAD, with reasonable safety profiles. A larger study may be needed to support the effect of probucol for cardiovascular prevention.

A one-year-old male Golden Retriever presented with acute onset of vomiting and hemorrhagic diarrhea since 2 days. The dog was depressed, showing abdominal pain, 12% dehydration, tachycardia, and a bounding pulse. Diagnostic imaging showed severe dilatation and fluid retention of the entire gastrointestinal tract with decreased motility. A foreign body was found in the gastroduodenal region, but there was no obstruction or plication. The dog was tentatively diagnosed with acute hemorrhagic diarrhea syndrome and rapidly recovered after supportive treatment. However, on the morning of day 4, anorexia and vomiting recurred, and diagnostic imaging revealed intestinal plication with free peritoneal fluid, not found on the previous image. An emergency laparotomy revealed the foreign body to be two used feminine hygiene products. These contaminated products were suspected to induce acute hemorrhagic diarrhea syndrome, and led to subsequent complication in this large dog.

Rabies virus (RABV), canine distemper virus (CDV), canine parvovirus type-2 (CPV-2), and canine influenza A virus (CIV) are important contagious pathogens in canine populations. To assess post-vaccination immunity against RABV, CDV and CPV-2, and serological evidence of exposure to influenza A virus in military working dogs (MWDs) in Korea, we tested blood samples of 78 MWDs by fluorescent antibody virus neutralization (FAVN) for RABV, and by commercially available enzyme-linked immunosorbent assay (ELISA) for CDV, CPV-2, and CIV. Korean MWDs had high antibody-positive rates against RABV (97.4%, ≥0.5 IU/ml), CDV (94.8%), and CPV (100%). All dogs tested seronegative (0/78; 0%) for influenza A virus. Two 1-year-old dogs stationed in known rabies outbreak areas (Gangwon and Gyeonggi) exhibited VNA titers below the protective level (0.06 and 0.29 IU/ml, respectively). The breed and sex of MWDs were not significantly associated with antibody titers for RABV, CDV, or CPV; however, age was significantly associated with CPV antibody titers, while region of residence was associated with CDV antibody titer. Taken together, the data presented here provide important insights necessary for post-vaccination management and control of infectious diseases in MWDs.

[Purpose] The purpose of this study was to measure gluteal pressure and center of force (COF) during sitting in children with cerebral palsy (CP). [Subjects and Methods] The participants were five children with CP and five typically developing controls. We measured peak gluteal pressure and COF using the TekScan system. During the measurements, all children sat on the therapeutic table for 1 minute without back and foot support. [Results] The peak gluteal pressure and COF in children with CP were significantly higher than values in controls. [Conclusion] This study suggests that it is important to distribute hip pressure evenly and transfer COF in a forward direction during rehabilitation in children with CP.

A 3-year-old French bulldog presented for evaluation of recurrent swelling and a fistula on the right cheek after a dog fight. A large volume of serous fluids was identified on the wound immediately after atropine drops. A diagnosis of parotid salivary duct rupture secondary to trauma was made. On surgical exploration, the thickened proximal segment of the severed duct was identified and circumferentially double ligated with 3-0 silk. No evidence of swelling and normal appearance of the parotid salivary gland was identified 4 months postoperative recheck. No further problems were noted 10 months postoperatively phone-call. To the author’s knowledge, this is the first reported case of successful proximal parotid duct ligation of parotid salivary duct rupture secondary to non-iatrogenic trauma.

Ulleungdo and Dokdo are volcanic islands that experience a characteristic marine climate, influenced by warm currents. The richness and diversity of the plant species, particularly vascular plants, are higher on Ulleungdo than on Dokdo. In contrast to the native plant life, little is known about the diversity of soil fungi living in the rhizosphere of these two islands. In this study, we utilized the barcoded pyrosequencing method to analyze rhizosphere soil fungi on Ulleungdo and Dokdo. In total, 768 operational taxonomic units (OTUs) were analyzed from the Ulleungdo samples, while 640 OTUs and 382 OTUs were analyzed from the Dongdo and Seodo (islets of Dokdo) samples, respectively. Species richness was considerably higher in the Ulleungdo samples than in the Dongdo and Seodo samples, while there was little difference in species diversity between the samples. The taxonomic composition analyses demonstrated that members of the phylum Basidiomycota dominated the Ulleungdo samples, whereas members of the phylum Ascomycota were predominant in the Dokdo samples. Ectomycorrhizal fungi belonging to the phylum Basidiomycota, in particular, were more abundant in the Ulleungdo samples. This finding suggests that the difference in the abundance of the ectomycorrhizal fungi in the rhizospheres of Ulleungdo and Dokdo may have been affected by species richness and diversity of the vascular plants. Our study is the first detailed report of the composition of soil fungal communities on the Ulleungdo and Dokdo islands. In addition, our findings provide a basis for understanding the ecological interactions between plants and fungi.

Dokdo, located east of the mainland of South Korea, is a volcanic island designated as a natural monument of South Korea due to its ecological value. Dokdo is divided into Dongdo and Seodo, islands with geological differences. The soil bacterial communities on Dokdo (Dongdo and Seodo) were analyzed using the pyrosequencing method. There were 1,693 and 1,408 operational taxonomic units (OTU) from Dongdo and Seodo, respectively. The statistical analyses (rarefaction curves as well as Chao1, Shannon, and Simpson indices) showed that bacterial diversity was slightly higher in Dongdo than Seodo. From results of a BLASTN search against the EzTaxon-e database, the validated reads (obtained after sequence preprocessing) were almost all classified at the phylum level. From the phylum level down to the species level, the number of classified reads considerably decreased due to the absence of information concerning unculturable or unidentified bacteria to date. Among the 36 phyla identified, three phyla (Proteobacteria, Actinobacteria and Acidobacteria) accounted for around 74.64%. The taxonomic composition was similar at the higher ranks (family and above) between Dongdo and Seodo, but a little different at the genus level. There were also various differences in the relative abundance of taxonomic ranks between Dongdo and Seodo. In particular, the proportion of the genus Acidobacterium (of the phylum Acidobacteria) was about six times higher in Seodo than Dongdo. In addition, the percentage of the genus Mycobacterium (of the phylum Actinobacteria) was nearly three times higher in Seodo than Dongdo, and the proportion of the genus Gaiella was about 3.7 times higher in Dongdo than Seodo. Overall, through the metagenomic analysis, the number of species identified in Dongdo and Seodo was 1,239 and 1,055, respectively. This information on the numerous culturable and unculturable bacteria is expected to help in the screening of new species in Dokdo.

A 9-year-old castrated male Shih-tzu dog was referred to us because of chronic vomiting. The patient’s hematological, radiographic, ultrasonographic, endoscopic, and histological examinations were evaluated for diagnosis. Hematologic analysis indicated moderate anemia and azotemia. Based on imaging study, oval-shape mass was identified in gastric pylorus area. A proliferative mass was found on endoscopic examination and we performed biopsy using grasping forceps. The histopathological findings of the biopsy specimens indicated hypertrophic gastritis and Y-U pyloroplasty was performed. However, the histopathological examination of surgically resected mass was identified as tubular adenocarcinoma of stomach. Then carboplatin chemotherapy was performed 4 times for 13 weeks. The clinical sign such as vomiting were resolved gradually after surgery and chemotherapy, and the patient’s condition was managed favorably until recently (30 months after surgery). This case report demonstrated clinical features, imaging studies, endoscopic characteristics, histopathological and immunohistochemical features of gastric tubular adenocarcinoma as early gastric cancer in a dog.

A 4-year-old female Maltese (case 1), a 9-year-old castrated male Shih-Tzu (case 2) and 2-year-old female Pomeranian (case 3) were presented because of neurological signs such as head tilt, ataxia, circling and paresis. Three cases were tentatively diagnosed to meningoencephalitis of unknown etiology based on computed tomography scan and cerebrospinal fluid analysis. All patients were managed with cyclosporine plus prednisolone therapy. The survival times of three patients were 170, 70 and 21 days, respectively. After cases expired, we performed necropsy and histopathological examination for definitive diagnosis. Based on the necropsy, histopathological and immunohistochemical examinations, case 1, 2 and 3 were definitely diagnosed to necrotizing meningoencephalitis, necrotizing leukoencephlaitis and granulomatous meningoencephalitis, respectively. This case report demonstrated that the clinical findings, brain CT characteristics, histopathological and immunohistochemical features of NME, NLE and GME in dogs and discussed about the reason of relatively short survival times under cyclosporine plus prednisolone therapy.
