        Bacterial phytopathogen Pectobacterium causes soft rot disease in several vegetable crops globally, resulting in heavy agricultural losses at both the pre and postharvest stages. The present work was carried out to screen Kimchi cabbage genetic resources conserved at the National Agrobiodiversity Center, Rural Development Administration, Korea, for resistance against the soft rot pathogen Pectobacterium carotovorum subsp. carotovorum KACC 21701 over a period of three years (from 2020 to 2022). Infection of the phytopathogen was carried out at four-leaf stage and for each accession, twenty-five plants per germplasm were infected with KACC 21701. Kimchi cabbage cultivars Wangmatbaechu, Seoulbaechu, and CR Kiyoshi were used as control. Seven-days post-infection, the Disease Index (DI) values were manually recorded from zero to four, zero matched perfectly heathy plants and four completely dead plants. The 682 accessions of Kimchi cabbage exhibited varying degrees of disease resistance to KACC 21701 and thirty accessions, exhibiting a DI≤2, were considered for replication studies. During the replication studies, four landrace germplasms (IT102883, IT120036, IT120044, and IT120048) and one cultivar (IT187919) were confirmed to be moderately susceptible to KACC 21701. Results of the preliminary screening as well as replication studies were documented for the all the 682 germplasms. Addition of such information to the passport data of stored germplasms might serve as potential bio-resource for future breeders and researchers to develop resistant varieties or study the mechanisms involved in resistance of plants to such phytopathogen.

        Looking at the dietary patterns of women in their 20s and 30s as well as postmenopausal women, the intake of most nutrients was lower than the recommended levels. Shrimp is a low-calorie, high-protein food, and contains abundant minerals, and it is expected to help prevent osteoporosis. In this study, jinmal dasik was prepared by varying the shrimp content at 0, 1, 5, and 7%, and the quality characteristics were measured. Hardness, adhesion, chewiness, and cohesiveness of physical properties increased significantly as the amount added increased (p<0.001). The springiness decreased significantly as the amount of addition increased in the addition group (p<0.001). In the calcium, there was a significant increase as the amount added increased (p<0.001). In the potassium, there was a significant increase as the amount added increased (p=0.049). This study intends to highlight the benefits and possible uses of shrimp.

        This study evaluated the effect of lactic acid bacteria (LAB, a mixture of Enterococcus faecium and Lactobacillus plantarum) supplementation, the storage temperature, and storage period on the fermentation characteristics and in vitro ruminal digestibility of a total mixed ration (TMR). The TMR was prepared into two groups, namely, CON (control TMR without the LAB) and ML (supplementing a mixture of E. faecium and L. plantarum in the ratio of 1% and 2% (v/w), respectively). Both groups were divided and stored at 4°C or 25°C for 3, 7, and 14 d fermentation periods. Supplementing LAB to the TMR did not affect the chemical composition of TMR except for the lactate and acetate concentration. Storage temperatures affected (p<0.05) the chemical composition of the TMR, including pH, lactate, and acetate contents. The chemical composition of TMR was also affected (p<0.05) by the storage period. During in vitro rumen fermentation study, the ML treatment showed lower (p<0.05) dry matter digestibility at 24 h incubation with a higher pH compared to the CON. There was no difference in the in vitro dry matter digestibility (IVDMD) of TMR between the CON and ML treatment however, at 24 h, ML treatment showed lower (p<0.05) IVDMD with a higher pH compared to the CON. The effects of storage temperature and period on IVDMD were not apparent at 24 h incubation. In an in vivo study using Holstein steers, supplementing LAB to the basal TMR for 60 d did not differ in the final body weight and average daily gain. Likewise, the fecal microbiota did not differ between CON and ML. However, the TMR used for the present study did include a commercial yeast in CON, whereas ML did not; therefore, results were, to some extent, compromised in examining the effect of LAB. In conclusion, storage temperature and period significantly affected the TMR quality, increasing acetate and lactate concentration. However, the actual effects of LAB supplementation were equivocal.

        Foot-and-mouth disease (FMD) is a very deadly and highly contagious disease that occurs in various cloven-hoofed animals. Korea imports vaccines including non-vaccinated serotype for the vaccine bank. The two company vaccines imported from 2019 to 2021 were evaluated through multiple tests based on national standard assay. SN titers for the vaccine of company A were more than 1.5 log10, those of company B vaccine in the geometric mean were at least 1.72. All imported vaccines exceeded the evaluation criteria, and the potency of each vaccine was above its own company standard. Stockpiled vaccines for emergency may help to control non-vaccinated serotypes of FMD outbreak nationally.

        Pseudo-pheochromocytoma is defined as an adrenal tumor that has the typical characteristics of pheochromocytoma likely hypertension but is histopathologically diagnosed to other types of adrenal tumors. 11-year-old, castrated male Maltese presented for a left adrenal mass with hypertension. According to clinical signs and radiological features, a temporary diagnosis was made of pheochromocytoma. The adrenalectomy was performed and the histopathological examination of the resected adrenal gland was diagnosed as cortical adenocarcinoma. This report describes the case of pseudo-pheochromocytoma in a dog and implies the salience that even if pheochromocytoma is diagnosed based on all test results, pseudo-pheochromocytoma should not be excluded.

        This study aimed to determine if animal-assisted therapy could enhance language and social interactions in autistic children. It is a single case study of a 6.7-year-old child diagnosed with second-rate autism disorder with a program of twelve sessions in total, a session per week, and fifty minutes per session. The program was constructed to increase the frequency of using words and to improve interpersonal relationships through contact with peers or strangers. To do this, SCAR and E-CLAC scales went through a pretest and posttest and the changes in main behaviors observed during the twelves sessions were analyzed, obtaining the following results: First, the animal-assisted therapy program allowed the autistic child to use daily words about twice more frequently than usual. Second, the animal-assisted therapy program was effective in allowing the autistic child to improve social interactions with peers or strangers around the dog. Therefore, the animal-assisted therapy program was effective in helping the autistic child enhance language and social interactions.

        A field experiment was conducted at Chishaka, Wedza district in the province of Mashonaland East, Zimbabwe during the 2020/2021 cropping season to determine effect of integrated nutrient management (INM) on cabbage (Brassica oleracea var. capitata) yields, net returns, and residual soil fertility. A total of six treatments were evaluated in a randomised complete block design (RCBD) with five replications. Treatments comprised T1 (control, 100% recommended chemical fertilizer), T2 (25% Cattle manure + 25% Chicken manure + 50% Ammonium nitrate), T3 (50% Compound S + 50% Chicken manure), T4 (50% Compound S + 25% Goat manure + 25% Chicken manure), T5 (farmer practice, 75% Compost + 25% Chicken manure), and T6 (50% Compost + 50% Chicken manure). All rates of organic manures were applied based on N equivalence. The soil was sandy loam with low soil organic carbon (1.28%), nitrogen (0.175%), and phosphorus (6.59 mg/kg) for all experimental plots. Results indicated that INM significantly improved soil and crop productivity. INM treatments T4, T3, and T2 recorded significantly maximum yield and yield components which were statistically at par. These treatments also gave the best strategy to improve major soil nutrients and maintain soil fertility. Similarly, the maximum net profit was obtained from combined application of treatments T4, T3, and T2. Treatment with 100% chemical fertiliser gave relatively lower yields and net benefit value than T4, T3, and T2. These results indicate that INM has the great potential to reduce the use of chemical fertilisers without decreasing soil fertility or crop yields. Therefore smallholder resource constrained farmers can adopt INM as a strategy, to enhance resource use efficiency and sustain soil health and crop productivity for improved livelihoods.

        The ambiguity of complex regional pain syndrome (CRPS) posed a challenge to many medical researchers in the early days after its discovery and continues to do so till date. The establishment of the Budapest Criteria of the International Association for the Study of Pain resolved certain queries on CRPS. Many aspects of CRPS, such as pathophysiology and etiology, remain unknown. Therefore, of these aspects, we focused on the genetic basis of CRPS. In this qualitative review, we summarized the recent findings on the genetic association of CRPS and analyzed the roles of genes identified in each study and limitations of the studies. In particular, we confirmed the reliability of each study by comparing the following research, which used the following control groups or the same candidate genes. Notably, specific phenotypes of CRPS with dystonia indicate a significant association with human leukocyte antigen (HLA)-DQ8. Further, HLA-DQ8, which is associated with aberrant CD4+ T-cell reaction, could be associated with CRPS etiology since an increased CD4+ T-cell population was reported in CRPS patients. In addition, matrix metalloproteinase (MMP)-9 found in genome-wide expression profiling is noteworthy since MMP-9 is associated with neuro-inflammatory reactions. Despite these suggestions on the genetic aspects of CRPS, the pathophysiology and etiology of CRPS may be polygenic and multifactorial, influenced by multiple genes and other factors. Further, some studies have suggested that CRPS phenotypes have different etiologies. Thus, further studies with the precise classification of CRPS on a unified basis and with a significant number of case groups are required

        This paper explores the L2 motivation of 11 students about to start studying English as junior college English majors. The participants took part in a ten-day L2 motivational program designed to help them with L2 skills and life on campus. To understand how they participated in the program, data gathered from online learning logs were coded using qualitative thematic analysis. Consequently, the participants shifted to embody ‘none to something’ qualities in terms of L2 selves and effort during the program. That is, they established self-images to believe in when using and learning English, which eventually developed into effort-driven attitudes and behavior. The students also set goals and plans according to their L2 selves created or revealed during the program. Although the program was comparatively short with a small number of participants entering a junior college, the findings indicate that an L2 motivational program for new adult students could be conducive to promoting and sustaining their effort, L2 selves, and motivation.
