BACKGROUND Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection. OBJECTIVE To compare the efficacy of a traditional herbal medicine (THM) regimen and transarterial chemoembolization (TACE) in preventing recurrence in post-resection patients with small HCC. DESIGN, SETTING...
BACKGROUND Epidemiological studies have used various measures to characterize trihalomethane (THM) exposures, but the relationship of these indicators to exposure biomarkers remains unclear. OBJECTIVES We examined temporal and spatial variability in baseline blood THM concentrations and assessed the relationship between these concentrations and several exposure indicators (tap water concentra...
A fast gas chromatography-mass spectrometry (GC-MS) method with minimum sample preparation is described for early diagnosis of tuberculosis (TB). The automated procedure is based on the injection of sputum samples which are then methylated inside the GC injector using thermally assisted hydrolysis and methylation (THM). The THM-GC-MS procedure was optimized for the injection of sputum samples. ...
This paper describes a new method for predicting trihalomethanes (THMs) presence in networks of water supply systems, using a low-cost device that permits a fast monitoring of concentrations without need of complex analysis made in laboratories. This method, based on statistical models, allows the estimation of THM concentration by monitoring parameters whose determination is direct and easy, a...
BACKGROUND Evidence for a relationship between trihalomethane (THM) or haloacetic acid (HAA) exposure and adverse fetal growth is inconsistent. Disinfection by-products exist as complex mixtures in water supplies, but THMs and HAAs have typically been examined separately. OBJECTIVES We investigated joint exposure at the individual level to THMs and HAAs in relation to birth weight in the mult...
A major challenge for modern steelmaking is the reduction of CO2 emissions. In this regard, blast furnace (BF) process critical due to its high associated This investigation assesses impact tuyere-injected fuels on BF Specifically, CFD results obtained previously at Purdue University Northwest are analyzed obtain emissions when natural gas (NG), syngas, hydrogen or hydrogen/NG injected. compare...
This paper describes a constrained bin-packing •problem (CBPP) and an approximate, anytime algor i thm for solutions. A CBPP is a constrained version of the bin-packing problem, in which a set of items allocated to a bin are ordered in a way to satisfy constraints defined on them and achieve near-optimality. The algor i thm for CBPP uses a heuristic search for labeling edges w i th a binary val...
BACKGROUND Various studies have shown that non-communicable diseases (NCDs) especially diabetes and hypertension are prevalent among older women living in South African urban areas, placing a heavy burden on the healthcare system. This study aimed to understand the health-seeking behaviour, healthcare practices and prevalence of traditional herbal medicine (THM) use among older women self-repor...
2014 Some aspects of the thermodynamic state of CdTe crystals grown by different zone passing techniques (sealed ingot zone refining technique and THM in tellurium solvent) are considered with regard to the general objective of getting high resistivity crystals. A vapour growth technique, called sublimation THM, which reduces several drawbacks of classical THM using a tellurium solvent, is deve...
Economic challenges associated with noncommunicable diseases (NCDs) and the sociocultural outlook of many patients especially in Africa have increased dependence on traditional herbal medicines (THMs) for these diseases. A cross-sectional descriptive study designed to determine the prevalence of and reasons for THM use in the management of NCDs among South African adults was conducted in an urb...
