OBJECTIVE This study aims to compare the efficacy and safety of T-tube free (TTF) versus T-tube drainage (TTD) after laparoscopic common bile duct exploration (LCBDE). BACKGROUND LCBDE has been proven to be an effective and preferred treatment approach for uncomplicated choledocholithiasis, and the appropriateness of T-tube placement after laparoscopic(More)
BACKGROUND The Short Musculoskeletal Function Assessment (SMFA) questionnaire is one of the most commonly used scales to evaluate functional status and quality of life (QOL) of patients with a broad range of musculoskeletal disorders. However, a Chinese version of the SMFA questionnaire for the psychometric properties of skeletal muscle injury patients in(More)
Transmission of the protozoan parasite Giardia intestinalis to vertebrate hosts presupposes the encapsulation of trophozoites into an environmentally resistant and infectious cyst form. We have previously shown that cyst wall proteins were faithfully sorted to large encystation-specific vesicles (ESVs), despite the absence of a recognizable Golgi apparatus.(More)
Algal assay using marine microalgae has emerged as an important method to evaluate the toxicity of chemicals, which is currently undertaken using conventional culture and additional detection of physiological cellular endpoints. While effective, this approach can be labor-intensive and thus could benefit from a more streamlined, integrated approach.(More)
The protozoan parasite Giardia intestinalis belongs to one of the earliest diverged eukaryotic lineages. This is also reflected in a simple intracellular organization, as Giardia lacks common subcellular compartments such as mitochondria, peroxisomes, and apparently also a Golgi apparatus. During encystation, developmentally regulated formation of large(More)
A novel continuous-flow bioreactor with aerobic granular sludge and self-forming dynamic membrane (CGSFDMBR) was developed for efficient wastewater treatment. Under continuous-flow operation, aerobic granular sludge was successfully cultivated and characterized with small particle size of about 0.1-1.0mm, low settling velocity of about 15-25 m/h, loose(More)
The problem of robust fault-tolerant control for networked control systems (NCSs) is discussed in this paper. The uncertainty of network-induced delays is converted to the uncertainty of the parameter matrix, and in order to eliminate the effect of the asynchronism the states are transformed into the augmented states. Based on Lyapunov stability theory and(More)
Stroke is a leading cause of death and disability, affecting millions of people worldwide with almost 80% of them as ischemic stroke and understanding the multiple mechanisms underlying cerebral ischemia is essential for development of effective treatments. To understand metabolic changes induced by focal brain ischemia, we conducted a comparative analysis(More)
BACKGROUND Vitamin A deficiency is recognized as a major public-health nutrition issue in the developing countries. Limited hospital sources and sample sizes are available in most of the existing studies associated with healthy school-age children. The aim of this study was to compare vitamin A status of 6- to 13-year-old healthy children in China between(More)
Antibody-derived fragments have enormous potential application in solid-phase assays such as biomarker detection and protein purification. Controlled orientation of the immobilized antibody molecules is a critical requirement for the sensitivity and efficacy of such assays. We present an approach for covalent, correctly oriented attachment of scFv antibody(More)
