THE DISTANCE COVERED OF SOCCER AND RUGBY REFEREES DURING THE MATCH USING A MOBILE "GPS"

The purpose of this study was to measure the distance covered of soccer and rugby referees during the match using mobile GPS method. And also, the distance covered measured by GPS method 'Nas compared with VTR method and manual tracing method, so as to examine availability of a mobile GPS. Nine soccer referees and ten rugby referees participated in this study. The distance covered was measured by mobile GPS method, VTR method and manual tracing method. In the case of soccer referee, there was no significant difference between mobile GPS method and VTR method. While the case of rugby referee, there was no significant difference among three methods. Therefore, it was concluded the mobile GPS might have the possibility of one effective instrument for measuring the referee's distance covered during soccer and rugby match

Secreted Phospholipase PLA2G2D Contributes to Metabolic Health by Mobilizing ω3 Polyunsaturated Fatty Acids in WAT

Polyunsaturated fatty acids (PUFAs) confer health benefits by preventing inflammation and obesity and by increasing thermogenesis in brown and beige adipocytes. As well as being supplied exogenously as nutrients, PUFAs are largely stored in membrane glycerophospholipids and released by phospholipase A2s (PLA2s). However, the molecular identity of the PLA2 subtype(s) that supplies endogenous PUFAs for metabolic homeostasis remains unclear. Here we show that PLA2G2D, a secreted PLA2 isoform, is constitutively expressed in M2-type macrophages in white adipose tissue (WAT) and shows a reciprocal correlation with obesity. Studies using global and macrophage-specific Pla2g2d-deficient mice reveal that PLA2G2D increases energy expenditure and thermogenesis by facilitating adipocyte browning, thereby ameliorating diet-induced obesity, insulin resistance, and WAT inflammation. Mechanistically, PLA2G2D constitutively supplies a pool of PUFAs, ω3 in particular, in WAT. Thus, our present findings underscore the contribution of the macrophage-driven PLA2G2D-ω3 PUFA axis to metabolic health

Pemphigus Vulgaris Confined to the Gingiva: A Case Report

Pemphigus Vulgaris (PV) is an autoimmune intraepithelial blistering disease involving the skin and mucous membranes. Oral mucosa is frequently affected in patients with PV, and oral lesions may be the first sign of the disease in majority of patients. In some patients, oral lesions may also be followed by skin involvement. Therefore, timely recognition and therapy of oral lesions is critical as it may prevent skin involvement. Early oral lesions of PV are, however, often regarded as difficult to diagnose, since the initial oral lesions may be relatively nonspecific, manifesting as superficial erosions or ulcerations, and rarely presenting with the formation of intact bullae. Lesions may occur anywhere on the oral mucosa including gingiva; however; desquamtive gingivitis is less common with PV than other mucocutaneous conditions such as pemphigoid or lichen planus. This paper describes the case of a patient presenting with a one-year history of painful gingival, who is finally diagnosed as having PV

Prevalence of Viral Frequency-Dependent Infection in Coastal Marine Prokaryotes Revealed Using Monthly Time Series Virome Analysis

海洋微生物も”密”ならウイルスに感染する --頻度依存的なウイルス感染を大阪湾で実証--. 京都大学プレスリリース. 2023-02-24.Viruses infecting marine prokaryotes have a large impact on the diversity and dynamics of their hosts. Model systems suggest that viral infection is frequency dependent and constrained by the virus-host encounter rate. However, it is unclear whether frequency-dependent infection is pervasive among the abundant prokaryotic populations with different temporal dynamics. To address this question, we performed a comparison of prokaryotic and viral communities using 16S rRNA amplicon and virome sequencing based on samples collected monthly for 2 years at a Japanese coastal site, Osaka Bay. Concurrent seasonal shifts observed in prokaryotic and viral community dynamics indicated that the abundance of viruses correlated with that of their predicted host phyla (or classes). Cooccurrence network analysis between abundant prokaryotes and viruses revealed 6, 423 cooccurring pairs, suggesting a tight coupling of host and viral abundances and their “one-to-many” correspondence. Although stable dominant species, such as SAR11, showed few cooccurring viruses, a fast succession of their viruses suggests that viruses infecting these populations changed continuously. Our results suggest that frequency-dependent viral infection prevails in coastal marine prokaryotes regardless of host taxa and temporal dynamics

ANALYSIS OF MATCH ACTIVITIES IN HIGH SCHOOL SOCCER PLAYERS USING A MOBILE GPS AND VTR METHODS

The purposes of this study were to obtain the match activity of high school soccer player, and to examine the measured value between GPS and VTR methods during a match play. The players' match activity ratios of total distance covered were walking 37.8%, jogging 16.6%, running 32.2%, sprinting 6.8%, back-walking 3.9% and back-running 3.1%, respectively. The total distance covered by GPS method was 5140.7 ± 476.6 m, and by VTR method was 5105.6 ± 459.8 m. As for the total distance covered, no significant difference was found between GPS and VTR methods. These finding,s gave suggestion that the distance covered by soccer player could be used with mobile GPS receiver. In the near future, more new accurate data will be got with GPS technique of new receiver in high quality

Desquamative Gingivitis

Desquamative gingivitis (DG) is characterized by erythematous, epithelial desquamation, erosion of the gingival epithelium, and blister formation on the gingiva. DG is a clinical feature of a variety of diseases or disorders. Most cases of DG are associated with mucocutaneous diseases, the most common ones being lichen planus, mucous membrane pemphigoid, and pemphigus vulgaris. Proper diagnosis of the underlying cause is important because the prognosis varies, depending on the disease. This chapter presents the underlying etiology that is most commonly associated with DG. The current literature on the diagnostic and management modalities of patients with DG is reviewed
