This study contributes to the health policy debate on medical systems integration by describing and analysing the interactions between health-care users, indigenous healers, and the biomedical public health system, in the so far rarely documented case of post-conflict Burundi. We adopt a mixed-methods approach combining (1) data from an existing survey on access to health-care, with 6,690 individuals, and (2) original interviews and focus groups conducted in 2014 with 121 respondents, including indigenous healers, biomedical staff, and health-care users...

Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small...

Lead (Pb) is a neurotoxic heavy metal, but the mechanism of its neurotoxicity is not clearly understood. Expression of metallothioneins (MTs) is induced in response to heavy metal exposure as a protective mechanism against heavy metal toxicity. There are several isoforms of MTs (MT-1 to 4), of which MT-3 is the neuron specific isoform, which also has neurite growth inhibitory effects. Whereas, the induction of MT-1 and 2 in response to Pb has been reported, the effect of Pb on the expression of MT-3 in the brain has not been documented...

House is the major site for malaria infection where most human-vector contact takes place. Hence, improving housing might reduce the risk of malaria infection by limiting house entry of vectors. This study aimed to explore the impact of screening doors and windows with wire meshes on density and entomological inoculation rate (EIR) of malaria vector, and malaria incidence, and assess the acceptability, durability, and cost of the intervention. The susceptibility status of malaria vector was also assessed. A two-arm randomized trial was done in Arba Minch Town, southwest Ethiopia...

Propolis, a resinous substance produced by honeybees, possesses various biological actions including anticancer activity towards tumor cells. Recently, the ethanol extract of Brazilian green propolis has been shown to induce autophagy, which is known to be induced in treatment of cancer cells with anticancer drugs, leading to cancer cell survival and decreased sensitivity to anticancer agents. In this study, we aimed to identify autophagy-inducing components of the propolis and elucidated the reciprocal relationship between anticancer cytotoxicity and protective autophagy in prostate cancer CWR22Rv1 cells...

Understanding racial/ethnic drinking patterns and service provision preferences is critical for deciding how best to use limited alcohol prevention, intervention, and treatment resources. We used nationally representative data from 150,727 U.S. high school seniors from 2005 to 2016 to examine differences in a range of alcohol use behaviors and the felt need to reduce or stop alcohol use based on detailed racial/ethnic categories, both before and after controlling for key risk/protective factors. Native students reported particularly high use but corresponding high felt need to reduce/stop use...

BACKGROUND: Local timber is still one of the main sources of work and income for mountain communities. However, illegal logging is a major cause of deforestation in many countries and has significant impacts on local communities and biodiversity. Techniques for tracing timber would provide a useful tool to protect local timber industries and contribute to the fight against illegal logging. Although considerable progress has been made in food traceability, timber provenance is still a somewhat neglected research area...

Since ancient times, opioids have been used clinically and abused recreationally. In the early stages (about 1,000 AD) of opium history, an Arab physician, Avicenna, administered opioids to control diarrhea and eye diseases. 1 Opioids have very strong pain relieving properties and they also regulate numerous cellular responses. Opioid receptors are expressed throughout the body, including the nervous system, heart, lungs, liver, gastrointestinal tract, and retina. 2-6 Delta opioid receptors (DORs) are a very attractive target from the perspective of both receptor function and their therapeutic potential...

Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable diversity of sex determination mechanisms. The underlying causes of this diversity remain unclear, and it is unknown if there are convergent trends in the directionality of turnover in sex determination mechanisms. We used the recently assembled Tree of Sex database to assess patterns in the evolution of sex determination systems in the remarkably diverse vertebrate clades of teleost fish, squamate reptiles, and amphibians...

Gut microbiota is a complex ecosystem, resident in the digestive tract, exerting multiple functions that can have a significant impact on the pathophysiology of the host organism. The composition and functions of this "superorganism" are influenced by many factors, and among them, the host's dietary habits seem to have a significant effect. Dietary changes in the evolution of human history and in the different stages of life of the human subjects are responsible for qualitative and functional modification of gut microbiota...

Finite element analysis (FEA) is a powerful tool for evaluating questions of functional morphology, but the application of FEA to extant or extinct creatures is a non-trivial task. Three categories of input data are needed to appropriately implement FEA: geometry, material properties, and boundary conditions. Geometric data are relatively easily obtained from imaging techniques, but often material properties and boundary conditions must be estimated. Here we conduct sensitivity analyses of the effect of the choice of Young's Modulus for elements representing trabecular bone and muscle loading complexity on the proximal femur using a finite element mesh of a modern human femur...

OBJECTIVE: Previous studies have highlighted that narrative skill is critical to the development of the literacy skills by children. Children with cochlear implants (CI) and hearing-aids (HA) may have problems in narrative development compared to peers with healthy hearing (HH). There is no exact data about the narrative writing ability of Persian-speaking students who are hearing-impaired. The current study was undertaken to compare the microstructure and macrostructure scores for narrative writing of Persian-speaking students who are hearing-impaired and peers with HH...

Kidney transplant is the optimal therapy for end stage renal disease, prolonging survival and reducing healthcare spending. Prior economic analyses of kidney transplant using Markov models, have generally assumed compatible, low risk, donors. The economic implications of using deceased donor kidneys with high kidney donor profile index (KPDI) scores, ABO incompatible or HLA incompatible living donors has not been assessed. The costs of transplant and dialysis were compared using discrete event simulation over a 10-year period, using data from the United States Renal Data System, Vizient ™ (Irving, Texas), and literature review...

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is more commonly diagnosed in males than in females. A growing body of research suggests that females with ADHD might be underdiagnosed or receive alternative diagnoses, such as anxiety or depression. Other lines of reasoning suggest that females might be protected from developing ADHD, requiring a higher burden of genetic risk to manifest the disorder. METHODS: We tested these two hypotheses, using common variant genetic data from two population-based cohorts...

Electroacupuncture preconditioning at acupoint Baihui (GV20) can reduce focal cerebral ischemia/reperfusion injury. However, the precise protective mechanism remains unknown. Mitochondrial fission mediated by dynamin-related protein 1 (Drp1) can trigger neuronal apoptosis following cerebral ischemia/reperfusion injury. Herein, we examined the hypothesis that electroacupuncture pretreatment can regulate Drp1, and thus inhibit mitochondrial fission to provide cerebral protection. Rat models of focal cerebral ischemia/reperfusion injury were established by middle cerebral artery occlusion at 24 hours after 5 consecutive days of preconditioning with electroacupuncture at GV20 (depth 2 mm, intensity 1 mA, frequency 2/15 Hz, for 30 minutes, once a day)...
