NBT staining was used to determine the presence of superoxide anions (O2-) produced by tiger shrimp (Penaeus monodon) hemocytes attached to a coverslip. When cells were treated with beta-glucan, blue granules were observed in 41% of studied hemocyte cytoplasm. For zymosan-treated, PMA-treated, and control cells, the percentages of hemocytes showing similar(More)
Non-specific disease resistance induced by yeast cell wall extract, beta-1,3-1,6-glucan, was demonstrated in the tiger shrimp. In this study beta-1,3-1,6-glucan was administered to shrimps by immersion before culturing and orally during the culturing period. Challenge of the treated shrimps with the virulent pathogens, Vibrio vulnificus and viral agents(More)
Beta-1,3-1,6-glucan, derived from bakers' yeast Saccharomyces cerevisiae, was used in the present study to investigate the extent to which glucan is able to protect spawners from white spot syndrome associated virus (WSSV), and whether this protection (if any) can be passed on to hatchlings via maternal transmission of immunity. Results showed that fewer(More)
The phenoloxidase (PO) activity of hemocyte lysate supernatant (HLS) from both tiger shrimp (Penaeus monodon) and giant freshwater prawn (Macro-branchium rosenbergii) was examined by treating HLS with various factors, such as an increase in temperatures from 25 to 70 degrees C, one of four elicitors (beta-1,3-1,6-glucan, zymosan, heat-killed Vibrio cells,(More)
Airway smooth muscle (ASM) cell phenotype modulation, characterized by reversible switching between contractile and proliferative phenotypes, is considered to contribute to proliferative diseases such as allergic asthma and chronic obstructive pulmonary disease (COPD). KCa3.1 has been suggested to be involved in regulating ASM cell activation,(More)
INTRODUCTION The objective of this study is to take into consideration the influence of baseline risk on the treatment effect and evaluate the effectiveness of standardized GINKGO BILOBA extract (GbE) on cognitive symptoms of dementia with the treatment period of approximately 6 months. METHODS We systematically searched the literature to identify all(More)
OBJECTIVE To assess the feasibility of using light-emitting diode fluorescence microscopy (LED-FM) in peripheral laboratories in China. DESIGN The performance of LED-FM and Ziehl-Neelsen (ZN) microscopy was compared on slides directly prepared from the sputum of tuberculosis (TB) suspects and follow-up patients on treatment. The examination time, fading(More)
Aquaporin-1 (AQP1) is the principle water channel in the peripheral nervous system (PNS) and is specifically localized to Schwann cells in the PNS. However, the pathophysiological role of AQP1 in peripheral nerves is poorly understood. Here, we utilized RNA interference by lentiviral transduction to specifically down-regulate AQP1 expression and a(More)
AIM To explore the role of magnetic resonance imaging (MRI) in detecting bone marrow infiltration of malignant lymphoma through a systematic review and meta-analysis. MATERIALS AND METHODS Studies that evaluated the diagnostic performance of MRI in detecting bone marrow infiltration of malignant lymphoma were acquired from the MEDLINE, EMBASE, Cancerlit,(More)
Lysyl oxidase is an essential catalyst for the cross-linking of extracellular collagen and elastin. Abnormalities in lysyl oxidase activity may contribute to the pathogenesis of arterial diseases characterized by abnormal matrix remodeling. This study tested the hypothesis that interferon (IFN)-gamma, a proinflammatory cytokine present in aortic aneurysm(More)
