Abstract
ATP-binding cassette super family (ABC) proteins are considered key to oncology and pharmacology studies. We examined the effect of benzene on ABC pump protein levels in C57BL/6 mouse bone marrow mononuclear cells. After a 2-week gavage (200 mg/kg, 5 days per week), the number of peripheral leukocytes, lymphocytes and basophils dropped significantly; there was also a significant decrease in MDR1 and MRP1 gene expression. A significant reduction in expression of P-gp was found; however, there was no significant decrease in the expression of MRP1 and NF-κB p65. We conclude that regulation of membrane efflux transport protein could be a factor in benzene hematotoxicity.

Abstract
OBJECTIVES Blood donors in Canada have been tested for Human T-Cell Lymphotropic Virus (HTLV) since 1990. We report the epidemiology, risk factors and lookback/traceback of HTLV-positive donors/recipients. METHODS The annual HTLV rate was calculated from 1990 to 2010. Residual risk was estimated as the product of incidence and window period. Twenty-nine HTLV-positive donors and 116 matched controls (ratio 1 : 4) were interviewed about risk factors. For HTLV-positive donations, lookback investigations involved identification of all previous donations, and attempting to locate and test recipients. Traceback was initiated when transfusion transmission was queried for HTLV-positive blood recipients. All donors of products that the recipient received were identified, with an attempt to locate and test them. RESULTS The HTLV rate decreased from 9.35 per 100,000 donations in 1990 to 1.11 in 2010. The residual risk of infection was 1 in 7.6 million donations. In logistic regression birth overseas (OR 18.7), history of sexually transmitted diseases (OR 32.9), sex with unknown background (OR 5.4) and blood transfusion (OR 8.9) were significant predictors. In the lookback study, of 109 HTLV-positive donors, 508 components were transfused, of whom 147 recipients were tested and 18 (12%) were positive. All were transfused prior to the implementation of donor testing. Twenty-three traceback investigations were requested involving 324 transfused untested products,of whom 219 (67.6%) of donors were tested and 13 (6%) were positive for HTLV. CONCLUSIONS With testing of the blood supply, the risk from HTLV is very low and while most HTLV-positive donors have risk factors, deferrable risk is rare.

Abstract
BACKGROUND In recent years, there were great controversies about gender disparities in stroke outcome. The study was aimed to investigate sex differences in stroke case fatality on all published studies based in a comprehensive meta-analysis. METHODS A systematic search of Pubmed, EMBASE, SCOPUS, ISI Web of Science, and Cochrane Library was conducted for the included papers between 1992 and 2009. For the pooled group and subgroup analysis, fixed effects or random effects model were used to find sex differences in case fatality of stroke with a Mantel-Haenszel method. Meta-regression analysis was performed to study methodological heterogeneity. RESULTS Thirty-six population-based studies, together with three randomized clinical trials (RCTs), were included in the present study. For the pooled group, there was an overall hazard risk of 1.13 for women compared with men. A hazard risk of 1.27 was observed for women in RCTs subgroup and 1.12 for women in population-based subgroup. The regression analysis found no significant correlation between methodological variables and heterogeneity. CONCLUSIONS Due to the limited data about sex differences in stroke case fatality, the findings should be treated cautiously as preliminary. More large multicenter clinical trials should be performed to verify the reliability of the results.

Abstract
OBJECTIVE To determine the efficacies of different preparations of glucosamine for the treatment of osteoarthritis (OA). METHODS Systematic searches of the bibliographic databases Medline, Embase, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews for randomised, double-blind, placebo-controlled trials (RCTs) concerning glucosamine treatment of OA. Effect size (ES) was estimated using Cohen's standardised mean difference. Consistency was evaluated via the I(2) index. RESULTS Nineteen trials (3159 patients) contributed to the meta-analysis, revealing a large degree of inconsistency among the trials in terms of pain-reduction outcome: the combined ES in glucosamine sulphate (GS) trials was -0.22 [95% confidence intervals (CI) -0.48, 0.04], I(2) was 82.3%. The combined ES in glucosamine hydrochloride (GH) trials was -0.03 (95% CI -0.14, 0.08), with an absence of heterogeneity. No treatment ES was observed [-0.38 (95% CI -0.99, 0.23)] favouring GS in trials of less than 24 weeks duration and the I(2) remained high (I(2) = 88.5%). No significant treatment ES -0.09 (95% CI -0.21, 0.03) was observed in trials of more than 24 weeks duration compared with placebo, with a heterogeneity of zero. In terms of function-modifying outcomes, GS showed no significant effect on Lequesne Index reduction vs. placebo in trials of less than 24 weeks duration (ES -0.55 (95% CI -1.22, 0.11)) with a high degree of heterogeneity (I(2) = 92.9%). Pooling data from studies with durations of more than 24 weeks presented a significant combined ES of -0.36 (95% CI: -0.56, -0.17) with an absence of heterogeneity. No risk of publication bias could be detected using Egger test. CONCLUSIONS GH is ineffective for pain reduction in patients with knee OA. GS may have function-modifying effects in patients with knee OA when administered for more than 6 months. However, it showed no pain-reduction benefits after 6 months of therapy.

Abstract
In this study, we report a robust agitation method for small-volume liquids. It utilizes an elastic diaphragm as the bottom of a liquid chamber, upon which an initial tension is also applied to enhance the aeroelasticity effects at small/micro scales. As a result, spontaneous vibration of the diaphragm can be induced by an external air flow, which further provides fluid agitations. The device structure is simple and can be easily fabricated at low cost. More importantly, the vibration amplitude is controllable and varies widely from several tens to several hundred micrometers depending on the applied air pressure. The resulting agitation is effective and applicable at high viscosities of up to 900 cSt. The influences of air pressure and liquid viscosity on the vibration frequency are discussed. Potential applications of this technique for solid particle agitation, focusing and fluid mixing are also demonstrated.

Abstract
Gonococcal inflammation of paraurethral glands around the external urethral orifice is a local complication of gonorrhoea in men. To investigate the risk factors for this complication we compared prepuce factors, Chlamydia trachomatis infection, demographic data and behavioural indicators of gonorrhoeal patients with and without this complication. Results showed that a prolonged disease course of gonorrhoea, sexual intercourse during gonorrhoea, repeated squeezing of the penis and a redundant prepuce were risk factors for this complication.

Abstract
Air sparging (AS) was explored for remediation of a petroleum contaminated semi-confined groundwater system in NE China. Physical, hydro-chemical and hydraulic behaviors in subsurface environment during AS were investigated with support of modeling to understand the hydrogeo-chemical impacts of AS on the aquifer. The responses of groundwater, dissolved oxygen and temperature indicated that the radius of influence of AS was up to 8-9 m, and a 3D boundary of the zone of influence (ZOI) was accordingly obtained with volume of 362 m(3). Water mounding unlike normal observations was featured by continuous up-lift and blocked dissipation. AS induced water displacement was calculated showing no obvious spreading of contaminant plume under this AS condition. Slug tests were employed before and after AS to reveal that the physical perturbation led to sharp increase in permeability and porosity. Modeling indicated that the regional groundwater flow field was not affected by AS except the physical perturbation in ZOI. Hydro-chemically increase of pH and Eh, and reduction of TDS, electrical conductivity and bicarbonate were observed in ZOI during AS. PHREEQC modeling inferred that these chemical phenomena were induced by the inorganic carbon transfer during air mixing.

Abstract
Obesity, and in particular central adiposity, is a key feature of metabolic syndrome, which includes trends toward increased triglycerides, insulin resistance, high blood pressure, hypercholesterolemia, and heart disease. It has a prevalence of 25% or more and is a dominant component of the health care budgets in Western societies. In addition to genetic causes, high-fat diets and disrupted sleep patterns have major influences on the development of metabolic syndrome. Recent studies have demonstrated active roles for the nuclear receptor superfamily and the energy-sensing kinase adenosine monophosphate (AMP)-activated protein kinase (AMPK) in regulating metabolism and circadian rhythm. In this chapter, we review these findings and attempt to develop a better understanding of the interplay between metabolism and circadian rhythm and their coordinated regulation by nuclear receptors and AMPK. This supraregulatory network may be considered a target for novel therapeutic applications against metabolic syndrome.

Abstract
Drug resistance is one of the major obstacles limiting the success of cancer chemotherapy. Biological mechanisms contributing to drug resistance may be present de novo and related to inherent features or may be raised after exposure to anticancer drugs. In recent years, both clinical observations and experimental studies suggested that steroid hormones and their receptors might also affect the therapeutic efficacy of antineoplastic drugs. Estrogens and estrogen receptors (ER) are well-known for their critical roles in the development and progression of breast tumors. It has long been known that breast tumors expressing ERα protein (ERα+) behave in a fundamentally different fashion than ERα-negative (ERα-) tumors with regard to their responses to hormonal therapy. Data obtained from both laboratory and clinical investigations suggested that some chemotherapeutic agents are clearly less effective in ERα+ tumors than ERα- tumors, although the mechanisms of ERα-mediated chemoresistance are not entirely clear. Moreover, recent studies from our laboratory and others demonstrated that the combination of antiestrogenic agents with chemotherapeutic drugs is of significant therapeutic benefit in ERα+ breast cancer over chemotherapy alone. In addition, the ERα-derived peptides, microRNAs specifically targeting ERα, as well as agents targeting estrogen-related receptors (ERRs) may hold promise to sensitize ERα+ breast tumors to chemotherapy. Considering that ERs are expressed in ˜ 65% of human breast cancer, the ERα-mediated chemoresistance has become a big challenge for clinical treatment. The hope to overcome this drug resistance relies on further clarification of specific pathways or molecules contributing to the resistance. More exhaustive and systematic studies are essential to reach deeper understandings on the underlying mechanisms and to develop novel approaches to sensitize ERα+ breast tumors to chemotherapy.

Abstract
We report a hydroelasticity-based microfluidic oscillator that converts otherwise steady laminar flow to oscillatory flow. It incorporates an elastic diaphragm to enhance nonlinearity of the flow. Negative differential flow resistance is observed. High-frequency oscillatory flow is produced passively through interactions among hydrodynamic, elastic and inertial forces, without resorting to external actuators and control equipment. Driven by fluid flow and pressure, this device can operate in either steady laminar flow or oscillatory flow states, or work as a valve. Its applications for flow control and operation, and mixing enhancement are demonstrated.
