Selenium is a trace element that, although toxic in higher concentrations, is essential for human and animal health. In this study, we looked at microarray-based gene expression patterns from liver and gastrocnemius tissues in mice fed either a selenium-deficient diet or diets containing sodium selenite, selenomethionine, or a yeast-derived selenium supplement. A p value cutoff of 0.

There is little rigorous evidence of the effectiveness of different intervention approaches. We describe findings of a cluster randomized trial of a community-based, multicomponent HIV, and reproductive health intervention aimed at changing social norms for adolescents in rural Zimbabwe.

Data were derived from a multi-method, qualitative sexual health needs assessment of 31 out-of-school adolescents in rural southwest Uganda. Grounded theory analysis allows contextual meanings of exchange to emerge.

Data were drawn from a sexual health needs assessment using applied anthropological techniques with young people aged 13-19 years. Parents, guardians and community leaders were also consulted.

Organic copper complexes such as copper tri- and tetraglycinates (GGG-Cu(II) and GGGG-Cu(II)) were used as model system. In a novel analytical approach the Ussing chamber was combined with mass spectrometry.

Practicing with a simulator model has been shown to speed the acquisition of these skills for various ultrasound-guided procedures. However, commercial models for ultrasound-guided regional anesthesia may be too costly or not readily available.

A corn-soybean meal diet without Cu and Zn supplementation, containing 31 mg of Zn/kg of diet and 6.6 mg of Cu/kg of diet, was used as a basal diet.

We report a single surgeon, single centre experience with 20 consecutive laparoscopic nephrectomies comparing them to 20 open cases performed prior to the establishment of a laparoscopic service.
Methodology: A retrospective comparative analysis was carried out over an 18 month period.
Purpose: The critical shortage of kidneys available for transplantation has led to alternate strategies to expand the pool. Transplantation of the 2 kidneys into a single recipient using organs suboptimal for single kidney transplantation was suggested. We assessed results in 24 grafts allocated for dual kidney transplantation vs those in a control group of 44 designated for single kidney transplantation.

This qualitative study investigated the experiences of mothers who have a child with communication difficulties resulting from cerebral palsy (CP). There is a dearth of information about parents' experiences of having a child with CP and communication difficulties. Three participants, whose children had moderate or severe CP and communication difficulties, were recruited from a voluntary organization.

However, the transfer of the chelates is not well understood and speciation studies may bring a comprehensive insight to further investigate the biological uptake mechanism(s) implicated. An analytical method was developed for the characterization of the water-soluble metal complexes in animal feed supplements obtained by reaction of a metal salt with a non-GMO soybean enzymatic digest.

The Russian government is discussing the initiation of compulsory treatment to bring illegal drug users to the treatment services. At the same time, there is no access to the evidence-based treatment for opiate addiction such as methadone and buprenorphine maintenance programs.

Methods: A cross-sectional survey of IDUs was conducted in six sites across Australia's eastern states to investigate IRID experience among Australian IDU. Correlates of IRIDs were explored using logistic and negative binomial regression analyses.
Objective: Glucagon-like peptide-1 (GLP-1) and gastrin promote pancreatic beta-cell function, survival, and growth. Here, we investigated whether GLP-1 and gastrin can restore the beta-cell mass and reverse hyperglycemia in NOD mice with autoimmune diabetes.
Research Design And Methods: Acutely diabetic NOD mice were treated with GLP-1 and gastrin, separately or together, twice daily for 3 weeks.
Background: Evidence of harms associated with temazepam gel capsule injecting among injecting drug users in Australia led to its withdrawal from manufacture in Australia. Subsequently, diphenhydramine gel capsule injecting was identified among a subset of ethnic Vietnamese injecting drug users.
Methods: Observational fieldwork around an active street-based illicit drug marketplace together with targeted purposive sampling enabled 66 ethnic Vietnamese injecting drug users to be recruited for in-depth interview.
Previous quantitative cross sectional studies of ethnic Vietnamese drug users in Melbourne have been overwhelmingly drawn from samples of men. In this qualitative investigation, 24 women aged between 18 and 33 years were interviewed. This exploratory study sought: to identify issues surrounding heroin initiation and drug use career; to examine relationships with family and primary sex partners; and to reveal participants' attitudes to drug treatment.

Methods: Cluster randomised trial of a multi-component HIV prevention intervention for adolescents based in rural Zimbabwe. Thirty communities were selected and randomised in 2003 to early or deferred intervention implementation.
Self-reporting of sensitive data is often unreliable, particularly when questions are asked about culturally or socially censured behaviours. This study aimed to improve the validity of questionnaire responses through cognitive interviewing of young people in Zimbabwe to better understand their underlying thought processes when responding to sexual behaviour questions. A questionnaire was developed in English and translated into Shona.

Objective: To report on the response rate achieved in a survey of medical practitioners and discuss the reasons for it.
Method: An on-line (internet-based) survey of all 609 registered pharmacotherapy prescribers in Victoria and Queensland; invitations to participate were sent by mail in late April 2007, and one reminder letter in late May 2007.
Results: Six hundred and nine invitation letters were mailed, nine were returned to sender, and 52 questionnaires completed, making the overall response rate 52/600 = 8.
Background: Discussion about coverage has primarily focused on answering the question: what level of coverage is required to reduce the spread of HIV among people who inject drugs? This paper documents the process involved in designing a Monitoring Information System (MIS) that provides a tool to estimate coverage, frequency of contacts as well as provides a mechanism for correlating these data with changes in risk behaviour among the surveyed population.
Methods: The system uses paper and pencil data collection forms to record information about the type and location of a contact. Information about the content of the contact such as the services, equipment or education that is delivered is also collected.
Objectives: To detect and quantify current risk factors for HIV seroconversion among gay men seeking repeat tests at sexual health clinics.
Design: Unmatched case control study conducted in London, Brighton and Manchester, UK.
Methods: 75 cases (recent HIV positive test following a negative test within the past 2 years) and 157 controls (recent HIV negative test following a previous negative test within the past 2 years) completed a computer-assisted self interview focused on sexual behaviour and lifestyle between HIV tests.
This study explored injection drug users' (IDUs) perceptions of drug abuse treatment and treatment providers in three Russian cities as well as their attitudes toward opiate substitution therapy, which is currently not available in Russia. Data were collected from 121 qualitative interviews with IDUs conducted in 2003-2004. Negative perceptions of available treatments were related to poor treatment outcomes, judgmental service providers, lack of psychologic services, and short lengths of stay in treatment.
