Mongolian herders rely significantly on grazing their animals, such as goats, sheep, cattle, horses, yaks, and camels, in broad rangelands throughout the year. The availability of appropriate forage, the amount of hay and forage to be kept, and whether the animals will acquire physical strength from the pasture to make it through the impending cold season are all determined by the meteorological conditions of the year. Herders' principal source of income is animals, therefore preventing mortality is a top priority. In Mongolia, meadows are a major element determining cattle live weight. However, in the summer of 2022, Mongolia faced a drought, which resulted in inadequate pastures and starved cattle. Livestock might lose weight in these situations due to a lack of supplemental feeding.

Excessive intake of sodium caused by high salt diet promotes the expression of inflammatory cytokines and differentiation of helper T cells resulting in inflammatory responses. High-glucose diet also contributes to the pathogenesis of periodontitis by inducing changes in the oral microbiome and reducing salivation. However, the effect of a high-salt and glucose diet (HSGD) on the prognosis of periodontitis remains unclear. In this study, a rat model of experimental periodontitis was established by periodic insertion of absorbable sutures containing Porphyromonas gingivalis and Fusobacterium nucleatum strains into the right gingival sulcus to analyze the effect of HSGD on the incidence and progression of periodontitis. The alveolar bone heights (ABH) was measured with microcomputed tomography imaging of the HSGD- and general diet (GD)-treated groups. The right ABH was significantly decreased compared to the left in both groups at 4 weeks after induction of inflammation; however, no significant difference was noted between the groups. Notably, the ABH in the HSGD-treated group was significantly decreased at 8 weeks after induction of inflammation, whereas in the GD-treated group, an increase in the ABH was observed; a significant difference of the ABH was noted between the two groups (p < 0.05). At 12 weeks, recovery of the alveolar bone was observed in both groups, with no significant differences in ABH between the two groups. These findings indicate that the intake of excessive sodium attenuates the recovery rate of the alveolar bone even after the local infectant is removed. In addition, this study demonstrates the use of HSGD in establishing a new animal model of periodontitis.

Near infrared reflectance spectroscopy (NIRS) has become increasingly used as a rapid and accurate method of evaluating some chemical compositions in forages and feedstuff. This study was carried out to explore the accuracy of near infrared spectroscopy (NIRS) for the prediction of chemical parameters of fresh whole crop barley silages. A representative population of 284 fresh whole crop barley silages was used as a database for studying the possibilities of NIRS to predict chemical composition. Samples of silage were scanned at 1 nm intervals over the wavelength range 680~2,500 nm and the optical data were recorded as log 1/Reflectance (log 1/R) and were scanned in fresh condition. NIRS calibrations were developed by means of partial least-squares (PLS) regression. NIRS analysis of fresh whole crop barley silages provided accurate predictions of moisture, acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP) and pH, as well as lactic acid content with correlation coefficients of cross-validation (R2cv) of 0.96, 0.81, 0.79, 0.84, 0.72 and 0.78, respectively, and standard error of cross-validation (SECV) of 1.26, 2.83, 2.18, 1.19, 0.13 and 0.32% DM, respectively. Results of this experiment showed the possibility of the NIRS method to predict the chemical parameters of fresh whole crop barley silages as a routine analysis method in feeding value evaluation and for farmer advice.

A 63-year-old woman with a history of nephrolithiasis and long-term hemodialysis (HD) presented with abdominal pain. Abdominal computed tomography (CT) showed urinoma induced by renal forniceal rupture, and three causative calculi. No active stone growth or new stones were observed when compared with previous CT, however, fragmentation and migration of an existing stone was observed. After ureteroscopic lithotripsy and stenting with a double-J catheter, the patient made a full recovery. To the best of our knowledge, this is the first case of spontaneous renal forniceal rupture in an anuric HD patient caused by calculi. Renal forniceal rupture can occur, even in anuric HD patients.

Cerebral infarction is one of the leading causes of death worldwide and the most common cause of death from a singledisease in South Korea. Each year, 795,000 people in the U.S. experience a new or recurrent stroke. Approximately 15-30% of cerebral infarctions are of embolic origin related to cardiac abnormalities. Because determination of the etiology of cerebral infarction is crucial to acute management and future prevention, clinicians should pay attention to finding the cardiac source of embolism in patients with cerebral infarction. We report on a case of cerebral infarction by a small papillary fibroelastoma on the mitral valve. The patient was treated with open heart surgery and closure of the patent foramen ovale to prevent further embolic events.

A reproducible transformation system via optimized regeneration media for Korean rice cultivars was established using Agrobacterium tumefeciens LBA4404 (pSBM-PPGN; gusA and bar). Although japonica rice genotypes were easier to produce transgenic plants compared to Tongil type cultivars, transformation efficiencies were not always correlated with regeneration efficiencies of non-transgenic callus on the control medium. Regeneration efficiencies of Donganbyeo, Ilmibyeo, and Manchubyeo were over 50% in non-transgenic control, however, transformation efficiencies were significantly low when only sucrose was added to the media as a carbon source. However, the medium, MSRK5SS-Pr (or MSRK5SM-Pr), that contains 5~textrmmgL-1 kinetin, 0.5~textrmmgL-1 NAA, 2 % sucrose (or maltose), 3% sorbitol, and 500~textrmmgL-1 proline, was the most efficient not only for regeneration of non-transgenic callus but also for regeneration of transgenic callus in the presence of L-phosphinotricin (PPT). Average transformation efficiencies of 16 Korean rice cultivars were significantly enhanced by using the optimized medium from 1.5% to 5.8% in independent callus lines and from 2.9% to 19.4% in tromsgenic plants obained. Approximately 98.9% (876 out of 885) transgenic plants obtained on optimized media showed basta resistance. Stable integration, inheritance and expression of gusA and bar genes were continued by GUS assay and PCR and Southern analysis of the bar gene. With Pst1 digestion of genomic DNA of transgenic plants, one to five copies of T-DNA segment were observed; however, 76% (19 out of 25 transgenic plants) has low copy number of T-DNA. The transformants obtained from one callus line showed the same copy numbers with the same fractionized band patterns.
