In this study, we evaluated the effects of tebuconazole on morphology and exploratory larvae behavior and adult locomotion. Furthermore, we analyzed the effects of this fungicide on AChE activity and gene expression in zebrafish larvae and in the adult zebrafish brain. Tebuconazole (4 mg/L) increased the ocular distance in larvae and reduced the distance travelled, absolute turn angle, line crossing and time outside area in exposed larvae. Moreover, adult zebrafish that were exposed to this fungicide (4 and 6 mg/L) showed a decrease in distance travelled and mean speed when compared to the control group...

Epidemiological investigations have shown that aluminium (Al) is an important neurotoxicant which can be absorbed by organisms via various routes. Previous studies have confirmed that exposure to Al could cause neurodegenerative diseases, decline CREB phosphorylation and then down-regulate the transcription and protein expression of its target genes including BDNF. However, recent studies revealed that CREB activation alone was far from enough to activate the expression of long-term memory (LTM) related genes; there might be other regulatory factors involved in this process...

BACKGROUND: Seeking treatment in formal healthcare for uncomplicated infections is vital to combating disease in low- and middle-income countries (LMICs). Healthcare treatment-seeking behaviour varies within and between communities and is modified by socio-economic, demographic, and physical factors. As a result, it remains a challenge to quantify healthcare treatment-seeking behaviour using a metric that is comparable across communities. Here, we present an application for transforming individual categorical responses (actions related to fever) to a continuous probabilistic estimate of fever treatment for one country in Sub-Saharan Africa (SSA)...

Network models of healthcare systems can be used to examine how providers collaborate, communicate, refer patients to each other, and to map how patients traverse the network of providers. Most healthcare service network models have been constructed from patient claims data, using billing claims to link a patient with a specific provider in time. The data sets can be quite large (106-108 individual claims per year), making standard methods for network construction computationally challenging and thus requiring the use of alternate construction algorithms...

BACKGROUND: Trauma systems improve outcome; however, it is unclear how geographic organization of trauma system resources (TSR) affects outcome. Our objective was to evaluate the relationship of fatal motor vehicle collisions (MVC) rates and the distance from individual MVC locations to the nearest TSR as a measure of the geographical organization of trauma systems, as well as how theoretical changes in the distribution of TSR may affect fatal MVC rates. METHODS: All fatal MVC in Pennsylvania 2013-14 were mapped from the FARS database...

BACKGROUND: Access to abortion care in the United States is limited by the availability of abortion providers and their geographic distribution. We aimed to assess how far women travel for Medicaid-funded abortion in California and identify disparities in access to abortion care. METHODS: We obtained data on all abortions reimbursed by the fee-for-service California state Medicaid program (Medi-Cal) in 2011 and 2012 and examined distance traveled to obtain abortion care by several demographic and abortion-related factors...

Understanding the dispersal of Aedes (aegypti (L.) Diptera: Culicidae) after consuming a potentially infectious bloodmeal is an important part of controlling the spread of the arboviruses it transmits. Because of the impact on abundance, removal of oviposition sites is a key component of vector control. However, source reduction around a case may encourage dispersal of potentially infected vectors. We compare the effect of oviposition site availability on Ae. aegypti dispersal behavior within 30-m linear cages in three model ecosystems at the University of Arizona's Biosphere 2 research facility...

BACKGROUND: Centralization of complex surgical care has led patients to travel longer distances. Emerging evidence suggested a negative association between increased travel distance and mortality after pancreatectomy. However, the reason behind this association remains largely unknown. We sought to unravel the relationships among travel distance, receiving pancreatectomy at high volume hospitals (HVH), delayed surgery, and operative outcomes. STUDY DESIGN: We identified 44,476 patients who underwent pancreatectomy for neoplasms between 2004 and 2013 at the reporting facility from the National Cancer Data Base...

We developed an explant model of the mouse eye and optic nerve that facilitates the study of retinal ganglion cell axons and mitochondria in the living optic nerve head (ONH) in an ex vivo environment. Two transgenic mouse strains were used, one expressing yellow fluorescent protein in selected axons and a second strain expressing cyan fluorescent protein in all mitochondria. We viewed an explanted mouse eye and optic nerve by laser scanning microscopy at and behind the ONH, the site of glaucoma injury. Explants from previously untreated mice were studied with the intraocular pressure (IOP) set artificially at normal or elevated levels for several hours...

PURPOSE: Radical cystectomy (RC) has become increasingly regionalized to high-volume hospitals. Our objective was to describe changes in regional market concentration and the distribution of RCs among hospitals, and examine how these changes affect patient travel distance to surgery. MATERIALS AND METHODS: We used the surveillance, epidemiology, and end results-Medicare database to identify patients who had RC for bladder cancer from 2001 to 2011. We defined RC market concentration within each Hospital Referral Regions (HRR) in surveillance, epidemiology, and end results using the Hirschman-Herfindhal Index...

OBJECTIVE: The study objective was to determine whether air travel in the immediate postoperative period after anatomic pulmonary resection is associated with increased morbidity or mortality. METHODS: All patients undergoing anatomic pulmonary resection at the Mayo Clinic (2005-2012) were identified and sent surveys querying their mode of transportation home after hospital dismissal and any complications encountered during or shortly after this travel. This included pneumonia, hospital readmission, deep venous thrombosis/pulmonary embolism, and specific pleural complications (pneumothorax, empyema, or chest tube placement)...

RATIONALE: Few studies suggest that antidepressants exert their effects by activating some signaling pathways, including the phosphatidylinositol 3-kinase (PI3K). Moreover, valproic acid (VPA) activates the PI3K pathway. Thus, here we investigated the antidepressant-like effect of VPA and if its effect is related to PI3K/Akt/mTOR activation. METHODS: C57Bl/6 (WT) and PI3Kγ(-/-) mice received VPA injections (30, 100 or 300mg/kg, i.p.) and 30minutes after they were submitted to the forced swimming (FS), tail suspension (TS) and open field (OF) tests...

The tropical freshwater snail Bulinus truncatus serves as an important intermediate host of several human and cattle Schistosoma species in many African regions. Despite some ecological and malacological studies, there is no information on the genetic diversity of B. truncatus in Egypt. Here, we sampled 70-100 snails in ten localities in Upper Egypt and the Nile Delta. Per locality, we sequenced 10 snails at a partial fragment of the cytochrome c oxidase subunit 1 gene (cox1) and we genotyped 25-30 snails at six microsatellite markers...

To explore the impact of road injuries for different age groups, this study compares the health burden of road injuries in young adolescents-12 to 17 years of age-to those for older age groups. Young adolescents are underrepresented in road fatalities. However, their inexperience, developmental stage and use of bicycles may expose them to high levels of road risk, but their physical resilience may help them survive injuries which in older age groups would be fatal. To assess the impact of injuries compared with death, this study assessed by age group the health burden expressed in disability adjusted life years; years of life lost plus years lived with disability...

This article discusses boundary integral simulations of dissolving drops flowing through a cylindrical tube for large aspect ratio drops. The dynamics of drop dissolution is determined by three dimensionless parameters: λ, the viscosity of the drop fluid relative to the suspending fluid; Ca, the capillary number defining the ratio of the hydrodynamic force to the interfacial tension force; and k, a dissolution constant based on the velocity of dissolution. For a single dissolving drop, the velocity in the upstream region is greater than the downstream region, and for sufficiently large k, the downstream velocity can be completely reversed, particularly at low Ca...

Robots have proven very useful in automating industrial processes. Their rigid components and powerful actuators, however, render them unsafe or unfit to work in normal human environments such as schools or hospitals. Robots made of compliant, softer materials may offer a valid alternative. Yet, the dynamics of these compliant robots are much more complicated compared to normal rigid robots of which all components can be accurately controlled. It is often claimed that, by using the concept of morphological computation, the dynamical complexity can become a strength...
