How organ-specific central tolerance is established and regulated has been an intriguing question. Lymphotoxin beta receptor (LTbetaR) deficiency is associated with autoimmune phenotypes characterized by humoral and cellular autoreactivity to peripheral organs. Whether this results from defective negative selection of T cells directed at tissue-restricted Ags has not been well understood. By tr...
BACKGROUND The pathological boundary of acute cholecystitis (AC) between early edematous and late chronic fibrotic inflammation beyond 72 h is well-described. Early laparoscopic cholecystectomy (ELC) is safe in AC but the timing still remains controversial. The aim of this study was to analyze the impact of the duration of symptoms on clinical severity, pathology and outcome in patients who und...
Chemokines can act as signal lamps for trafficking of lymphocytes at the important crossing points of lymphoid tissues. Lymphoid progenitors at different differentiation stages are differentially localized in primary lymphoid tissues and have differential responsiveness to thymic or bone marrow chemokines: SDF-1, CKbeta-11/MIP-3beta/ELC, SLC/6Ckine/Exodus2, MIP-1beta, and TECK. Naive T cells an...
Patients with choledochocystolithiasis are usually treated by endoscopic retrograde cholangiography with endoscopic sphincterotomy (ES) followed by laparoscopic cholecystectomy (LC). LC after ES is more difficult than in uncomplicated gallstone disease, possibly due to bacterial colonization of the common bile duct. The goal of this study was to evaluate if bactobilia influences the peri- and p...
IRF4 promotes cutaneous dendritic cell migration to lymph nodes during homeostasis and inflammation.
Migration of resident dendritic cells (DC) from the skin to local lymph nodes (LN) triggers T cell-mediated immune responses during cutaneous infection, autoimmune disease, and vaccination. In this study, we investigated whether the development and migration of skin-resident DC were regulated by IFN regulatory factor 4 (IRF4), a transcription factor that is required for the development of CD11b...
The twentieth century saw rapid environmental degradation due to changes that contributed increased net GHG emissions, loss of natural ecosystems, and declining biodiversity. Deterioration unprotected landscapes during swift industrialization, urbanization, increasing monocultures in agriculture, expansion commercial production significantly these negative consequences. However, a cultural shif...
Electronic Line Calling (ELC) is an auxiliary referee system used for tennis matches based on binocular vision technology. While ELC has been widely used, there are still many problems, such as complex installation and maintenance, high cost etc. We propose a monocular technology method. The method the following steps: (1) locate ball’s trajectory. multistage ball positioning approach combining...
A hydroelectric power plant is an electrical energy generator that utilizes water to drive a turbine coupled generator. The main problem in plants the frequency and voltage fluctuations due consumer loads. purpose of this research make prototype Electronic Load Controller (ELC) system at Pico Hydropower Plant. part ELC sensor gating system. first made by Zero Crossing Detector, which detects fr...
Pada sebuah pembangkit listrik tenaga pikohidro (PLTH) diperlukan kontrol beban konsumen supaya generator tidak mengalami kerusakan akibat stabilnya tegangan dan arus keluaran generator. Electronic load control (ELC) merupakan pilihan untuk mengatur tersebut. Namun, ELC di pasaran menggunakan konfigurasi ballast dengan pengendalian yang memanipulasi gelombang masukannya besarnya ballast, sehing...
