This paper presents the geometric optimal design of magnetorheological (MR) valves in order to improve valve performance, such as pressure drop. The optimization problem is find dimensions MR constrained a specific volume. After describing configuration valves, their drops are investigated on basis Bingham model an fluid. Then, ratio, which objective function, derived by considering field-dependent (controllable) and viscous (uncontrollable) valves. Subsequently, procedure using...
Obovatol isolated from the medicinal herb Magnolia obovata exhibits a variety of biological activities. Here, effect obovatol and its mechanism action on microglial activation, neuroinflammation neurodegeneration were investigated.In BV-2 cells stimulated with lipopolysaccharide (LPS), we measured nitric oxide (NO) cytokine production, activation intracellular signalling pathways by reverse transcription-polymerase chain reaction Western blots. Cell death was assayed in co-cultures activated...
Nonsteroidal anti-inflammatory drugs (NSAIDs), the most highly prescribed in world for treatment of pain, inflammation, and fever, are associated with gastric mucosal damages including ulcer directly or indirectly. This study was aimed to document preventive effects an organosulfur constituent garlic, S-allyl cysteine (SAC), against NSAIDs-induced damages, as well elucidation its pharmacological actions, such anti-inflammatory, anti-oxidative, cytoprotective actions.Different doses SAC were...
To prove whether dietary intervention can prevent Helicobacter pylori-induced atrophic gastritis and gastric cancer, we developed cancer preventive kimchi (cpKimchi) through special recipe administered to chronic H. pylori-initiated, high salt diet-promoted, tumorigenesis mice model. pylori-infected C57BL/6 were with cpKimchi mixed in drinking water up 36 weeks. Gross pathological lesions evaluated after 24 weeks, respectively explored underlying molecular changes explain efficacies. Cancer...
This paper presents vibration and position control of a flexible beam structure by adopting shape memory alloy (SMA) wire actuators. The governing equation motion the proposed is obtained via Hamilton's principle. dynamic characteristics SMA actuator are experimentally identified incorporated with to furnish system model in state space. Subsequently, sliding mode controller which has inherent robustness external disturbances parameter uncertainties formulated. then empirically realized for...
PRKAA (protein kinase, AMP-activated, α catalytic subunit) regulates mitochondrial biogenesis, function, and turnover. However, the molecular mechanisms by which dynamics remain poorly characterized. Here, we report that regulated fission via autophagy-dependent degradation of DNM1L (dynamin 1-like). Deletion Prkaa1/AMPKα1 or Prkaa2/AMPKα2 resulted in defective autophagy, accumulation, aberrant fragmentation mouse aortic endothelium. Furthermore, autophagy inhibition chloroquine treatment...
Abstract Objective In spite of cytoprotective and anti‐inflammatory actions, conventional licorice extracts (c‐lico) were limitedly used due to serious side effects glycyrrhizin. As our group had successfully isolated special (s‐lico) lowering troublesome glycyrrhizin, but increasing licochalcone A, we have compared anti‐inflammatory, antioxidative, actions s‐lico c‐lico against either in vitro or vivo H elicobacter pylori infection. Methods RT ‐ PCR W estern blot performed check action...
Numerous studies have demonstrated that diets containing an increased ratio of ω-6 : ω-3 polyunsaturated fatty acids (PUFAs) are a risk factor for colon cancer and might affect tumorigenesis. Therefore, dietary PUFA administration may be preventive strategy against cancer. Until now, the exact molecular mechanisms required doses PUFAs prevention were unknown. In this study, we explored anti-tumorigenic colitis-associated (CAC) model. Through in vitro cell models involving docosahexaenoic...
We developed a compact, wearable diagnostic imaging modality employing optical coherence tomography for in situ plant leaf quality assessments. This system is capable of diagnosing infected leaves at the initial disease stages. Our versatile backpack-type with compact spectrometer, miniature computer, rechargeable power source, and handheld inspection probe. method enhances real-time specimen through direct implementation plantation. To evaluate performance, field experiments were conducted...
Cancer cachexia is a syndrome accompanying weight loss, skeletal muscle atrophy, and loss of adipose tissue in patients with advanced cancer. Since interleukin-6 (IL-6) one core mediators causing cancer kimchi can modulate IL-6 response, we hypothesized dietary intake ameliorate cachexia. In this study, studied preemptive administration mouse colon carcinoma cells (C26) adenocarcinoma-induced explored anti-cachexic mechanisms focused on the changes cachexic inflammation, catabolic...
Oxygen vacancies are a major factor that controls the electrical characteristics of amorphous indium-gallium-zinc oxide transistor (a-IGZO TFT). affected by composition ratio a-IGZO target and injected oxygen flow rate. In this study, we fabricated three types TFTs with different rates then investigated changes in characteristics. Atomic force microscopy (AFM) was performed to analyze surface morphology films according gas Furthermore, X-ray photoelectron spectroscopy (XPS) analysis confirm...
