Glutamine has been used to treat canine patients with parvoviral enteritis. However, little is known about the effect of L-alanyl-L-glutamine (Ala-Gln) supplementation in dogs with parvoviral enteritis. The objective of this study was to determine whether Ala-Gln supplementation can improve dog survival and ameliorate clinical signs without adverse effects. We conducted a randomized, double-blind, placebo-controlled clinical trial involving 39 client-owned dogs. The dogs were randomly assigned to two groups and administered either an Ala-Gln solution (Dipeptiven, 0.4 g/kg, n = 20) or an equivalent volume of placebo (n = 19) orally twice daily. Of the 39 dogs, 17 were vaccinated (n = 9 in the Ala-Gln-treated group and n – 9 in the placebo group). All dogs received standard treatment while hospitalized. The dogs were monitored according to a clinical scoring system and evaluated diagnostically daily for 11 days. Survival rates in both groups were quantified using Kaplan‒Meier survival curves and statistically compared using the log-rank test. The total score for clinical signs did not differ between the groups, except on day 2. The survival rates differed significantly (p=0.038). Three Ala-Gln-treated dogs (15.0%) died during the study, whereas eight dogs in the placebo group died (42.1%). No adverse effects were found to be associated with Ala-Gln treatment. Oral administration of Ala-Gln improves survival in dogs with parvoviral enteritis without causing adverse effects.

A one-year-old, intact male Maltese was referred with dehydration, anorexia, and marked hyperglycemia. The dog had been managed due to meningoencephalitis of unknown etiology (MUE) for three months. The dog had been treated with long-term prednisolone administration. Diabetic ketoacidosis (DKA) was identified based on the blood chemistry and venous gas analyses, and intensive treatments including insulin administration were initiated. On further examinations, there was no any other disease that contributed to the occurrence of DKA. Insulin resistance resulted from the administration of prednisolone was highly suspected, but the agent could not be tapered due to managing MUE. Following resolution of DKA, the dog was discharged with life-long insulin and prednisolone therapy. Over the next two years, the dog continued to be routinely re-evaluated and was managed with permanent insulin therapy (0.8–1.4 units/kg SC 12 hourly) and medications including prednisolone (0.4–1.1 mg/kg PO 12 hourly). Because MUE severely progressed, the dog was euthanized by owner’s request. Histopathologic examination of pancreas obtained by post-mortem revealed that both endo- and exocrine pancreas was within normal limit. The case described herein showed the risk of ketoacidosis as well as hyperglycemia after long-term prednisolone administration in a dog without pancreatic islet pathology.

A one-year-old, intact female, Maltese dog was presented with a history of anorexia and regurgitation. Thoracic radiographs and ultrasonography scans suggested an abnormal mass in the cranial mediastinal region, and computed tomography confirmed the origin of this mass. Ultrasound-guided fine needle aspiration cytology showed the presence of intermediate to large lymphoid cells showing mitotic figures. B-cell lymphoma was confirmed by the result of a polymerase chain reaction assay for antigen receptor rearrangement, therefore the patient was diagnosed with primary mediastinal large B-cell lymphoma (PMBL). The patient underwent L-CHOP (L-asparaginase, cyclophosphamide, doxorubicin, vincristine, prednisolone)-based chemotherapy, and showed complete tumoral remission from the beginning of chemotherapy. Seventytwo weeks after the completion of chemotherapy, the patient is still alive without any evidence of metastasis or relapse. A standardized treatment protocol has yet to be established for primary mediastinal lymphoma in dogs. This case report describes the complete remission of PMBL by an L-CHOP-based chemotherapy protocol in a young Maltese. Clinicians should consider that L-CHOP based chemotherapy may be useful against PMBL in dogs.

We report a carbothermal reduction process for massive synthesis of monolithic WO phase from tungsten oxide in the presence of carbon source. Carbon black powder was used as a carbon source and added to WO by 40 weight percent. Bundles of WO rods were formed over the temperature range of 80 to 90. Pure WO bundles could be separated from the mixture of WO and residual carbon black powder. Field emission character of WO phase was determined using the extracted WO rods. Flat lamp fabricated from the WO rods showed the turn-on field of 9.3 V/

Clubroot is a devastating disease caused by Plasmodiophora brassicae and results in severe losses of yield and quality in Brassica crops including Brassica oleracea. Therefore, it is important to identify resistance gene for CR disease and apply it to breeding of Brassica crops. In this study, we applied genotyping-by-sequencing (GBS) technique to construct high resolution genetic map and mapping of clubroot resistance (CR) genes. A total of 18,187 GBS markers were identified between two parent lines resistant and susceptible to the disease, of which 4,103 markers were genotyped in all 78 F2 plants generated from crossing of both parent lines. The markers were clustered into nine linkage groups spanning 879.9 cM, generating high resolution genetic map enough to refine reported reference genome of cabbage. In addition, through QTL analysis using 78 F2:3 progenies and mapping based on the genetic map, two and single major QTLs were identified for resistance of race 2 and race 9 of P. brassicae, respectively. These QTLs did not show collinearity with CR loci found in Chinese cabbage (Brassica rapa) but roughly overlapped with CR loci identified in cabbage for resistance to race 4. Taken together, genetic map and QTLs obtained in this study will provide valuable information to improve reference genome and clubroot resistance in cabbage.

The research concerned of the regeneration of plants from embryos obtained from anther cultures of ginseng (Panax ginseng C. A. Meyer). The aim was to determine the influence of the regeneration medium on the efficiency of the regeneration process. We conducted to determine the optimum conditions such as cold pretreatment, plant growth regulators and carbon sources on anther culture of P. ginseng. Highest callus formation rate was obtained when flower buds pretreated at 4℃ for 1 day. Among the treated growth regulators with various degrees of concentration in Murashige and Skoog's (MS) medium, 4.53 μm of 2.4-dichlorophenoxyacetic acid and 4.44 μm of 6-benzylaminopurine gives the most responsive callus with the frequency of 73.89% and 129.53 g of fresh weight. When we used 3-9% of sucrose and maltose among the different kinds and various concentrations of carbohydrates, callus was formed highest 67.29% in the medium with 3% of sucrose. Shoots induced from callus supplemented with 28.9 μm of gibberellic acid and rooted in Gamborg's B5 medium supplemented with 14.7 μm of indole-3-butyric acid.

Miniature inverted- repeat transposable elements are expected to play vital role in evolution of genes and genome of major eukaryotic organisms. However, there have been little reports on MITEs in B. rapa, a polyploidy model genome. We identified 13 novel MITE families in B. rapa genome by computational approach. Out of 13 MITEs families three, eight and two were classified under stowaway-like, tourist-like and hAT super families based on their unique structural characteristics. We characterized the members of 13 MITE families from the available 256 Mbp from whole genome draft sequences of B. rapa. We found ech MITE has high copiy number ranges from 14 to 977 which are distributed randomly along all the chromosomes. We also found more than 40% of the MITE members were associated with genes and gene rich regions. Furthermore, the polymorphism due to insertion and non-insertion of MITEs analysis suggest that MITEs are active in the genome. As, such the newly identified MITEs will provide a foundation for the further analysis of roles of MITEs in gene and genome evolution.

family in the Brassica genome sequences by computational approach. The MITE family showed a total of 264bp length including 36bp terminal inverted repeats and remained 2bp (TA) targets it eduplication by its insertion. By searching the genome database of Brassica species, 516, 227, and 15 members were identified from 470Mbp of Brassica oleraceae, 154Mbp of B.rapa and 15Mbp of B.napus, respectively, indicating that there are approximately 692, 760, 1235 copies in B.oleracea, B.rapa and B.napus genomes,respectively. A total of 225 relatively intact MITE members, 146,68, and 11 members, which showed >80% sequence similarity and sequence coverage were identified and retrieved for MITE analysis from B.oleracea, B.rapa and B.napus genomes, respectively. Out of 225 MITE family members 159 having full structure of MITE and 66 having the truncated end either in right TIR or left TIR. Insertion polymorphism due to insertion or non-insertion of MITEs showed high level of polymorphism among accessions intra and inter species of Brassica. The new MITE would provide abetter tool for study molecular breeding in Brassica species and also helpful to understand their contribution in evolution and diversification of the highly duplicated Brassica genome.

Perilla is a genus as a member of the mint family Lamiaceae which is known to contain lots of volatile metabolite. Perilla has been called as ‘deulkae’ indicating ‘wild sesame’ that means it has been maintained in Korea with long history. It has been very friendly used as edible oil and as fresh leaf vegetable. Perilla oil is valued for its medicinal benefit because it contains best amounts of unsaturated fatty acids, especially for the alpha-linolenic acid, known to omega-3 fatty acid, among all of the plant oils. It also include many beneficial phytochemicals. However, little study is conducted on their genetics. Here, we announce construction of well normalized and full length enriched-perilla cDNA library from a whole plant of one cultivar ‘Youngho-deulkae’ and their sequence characterization to provide useful resources for genetics, breeding and metabolite engineering. By sequencing of 5,760 cDNA clones, we 5,438 high quality EST sequences. Sequence trimming and assembly resulted 3,995 unigenes which consists 1,004 contigs and 2,991 singletones. Unigenes that showed little homology at the DNA sequence level with known genes in other plants even though they showed similarity at the protein domain level based on BLASTN, BLASTX, and TBLASTX. This study may provide good resources for initiation of further genomics, comparative genomics, functional genomics such as metabolic engineering and molecular breeding.
