These results demonstrate that thiol-bound Hg is bioavailable to E. coli and that this bioavailability is higher in Hg-resistant bacteria with a complete Mer system than in non-resistant strains. No difference in the uptake rate of Hg from Hg(GSH)2 was observed in E. coli strains with or without functioning glutathione transport systems. There was also no difference in uptake rates between a wildtype Bacillus subtilis strain with a functioning cystine/cysteine transport system, and a mutant strain where this transport system had been knocked out. These results cast doubt on the viability of the hypothesis that the entire Hg-thiol complex is taken up into the cell by a thiol transporter. It is more likely that the Hg in the Hg-thiol complex is transferred to a transport protein on the cell membrane and is subsequently internalized.The application of the organophosphate larvicide temephos to water storage containers is one of the most commonly employed dengue vector control methods. This systematic literature review is to the knowledge of the authors the first that aims to assess the community-effectiveness of temephos in controlling both vectors and dengue transmission when delivered either as a single intervention or in combination with other interventions. A comprehensive literature search of 6 databases was performed (PubMed, WHOLIS, GIFT, CDSR, EMBASE, Wiley), grey literature and cross references were also screened for relevant studies. Data were extracted and methodological quality of the studies was assessed independently by two reviewers. 27 studies were included in this systematic review (11 single intervention studies and 16 combined intervention studies). All 11 single intervention studies showed consistently that using temephos led to a reduction in entomological indices. Although 11 of the 16 combined intervention studies se is associated with reductions in dengue transmission.One of the main goals of conservation biology is to understand the factors shaping variation in biodiversity across the planet. This understanding is critical for conservation planners to be able to develop effective conservation strategies. Although many studies have focused on species richness and the protection of rare and endemic species, less attention has been paid to the protection of the phylogenetic dimension of biodiversity. We explored how phylogenetic diversity, species richness, and phylogenetic community structure vary in seed plant communities along an elevational gradient in a relatively understudied high mountain region, the Dulong Valley, in southeastern Tibet, China. As expected, phylogenetic diversity was well correlated with species richness among the elevational bands and among communities. At the community level, evergreen broad-leaved forests had the highest levels of species richness and phylogenetic diversity. Using null model analyses, we found evidence of nonrandom phylogenetic structure across the region. Evergreen broad-leaved forests were phylogenetically overdispersed, whereas other vegetation types tended to be phylogenetically clustered. We suggest that communities with high species richness or overdispersed phylogenetic structure should be a focus for biodiversity conservation within the Dulong Valley because these areas may help maximize the potential of this flora to respond to future global change. In biodiversity hotspots worldwide, we suggest that the phylogenetic structure of a community may serve as a useful measure of phylogenetic diversity in the context of conservation planning.Glioma, one of the most common aggressive malignancies, has the highest mortality in the present world. Delivery of nanocarriers from the systemic circulation to the glioma sites would encounter multiple physiological and biological barriers, such as blood-brain barrier (BBB) and the poor penetration of nanocarriers into the tumor. To circumvent these hurdles, the paclitaxel-loaded liposomes were developed by conjugating with a TR peptide (PTX-TR-Lip), integrin αvβ3-specific vector with pH-responsible cell-penetrating property, for transporting drug across the BBB and then delivering into glioma. Surface plasmon resonance (SPR) studies confirmed the very high affinity of TR-Lip and integrin αvβ3. In vitro results showed that TR-Lip exhibited strong transport ability across BBB, killed glioma cells and brain cancer stem cells (CSCs), and destroyed the vasculogenic mimicry (VM) channels. In vivo results demonstrated that TR-Lip could better target glioma, and eliminated brain CSCs and the VM channels in tumor tissues. The median survival time of tumor-bearing mice after administering PTX-TR-Lip (45 days) was significantly longer than that after giving free PTX (25.5 days, p less then 0.001) or other controls. In conclusion, PTX-TR-Lip would improve the therapeutic efficacy of brain glioma in vitro and in vivo.It is an interesting issue if the transport behavior of a piezoelectric tunnel junction is sensitive to external strain or stress, and it implies a prospect for developing novel mechanical sensors, transducers, piezotronic devices, etc. Many studies paid attention to this issue, yet how the strain and stress tunable transport behavior of a tunnel junction depends on the barrier thickness is still rarely known. Using the first principles calculations, we investigate the size-dependent and strain-tunable transport behavior in the tunnel junctions. It was confirmed that external strain has strong control over the transport properties of ZnO tunnel junctions, with several times amplification of tunnel conductance obtained by strain reversal. More importantly, the conductance amplification by strain reversal exponentially changes with the barrier thickness, indicating the size-dependent strain tunability of the transport behavior. The electrostatic quantities (i.e., built-in field, depolarization field, polarization, interfacial dipoles and potential barrier) and the transport properties of tunnel junctions were comprehensively analyzed to reveal the relationships between these quantities and their size dependence. The exponential size-dependence of strain tunable transport behavior in ZnO tunnel junctions is attributed to the linear change in the potential barrier with the barrier thickness. Our simulations provide an insight of how to maximize the strain tunability of transport behavior of piezoelectric tunnel junctions by thickness design and strain engineering.
To evaluate the nature and extent of lacrimal apparatus injury in children after eyelid laceration from a dog bite.

A retrospective chart review of all eyelid lacerations treated between 1990 and 2012 at Boston Children's Hospital, Boston, Massachusetts, was conducted. Seventy-three patients who sustained an eyelid laceration due to dog bite were identified and were matched 51 with a randomly selected cohort of 365 patients from the group of 1,177 patients who had sustained eyelid lacerations from other causes during the same time period.

Of the 73 patients who sustained an eyelid laceration due to a dog bite, 26 (35.62%) had damage to the lacrimal apparatus. This was statistically significant when compared to patients who sustained eyelid lacerations from other causes, in which 13 (3.56%) patients had damage to the lacrimal apparatus (P < .000001). The inferior canaliculus was the most commonly involved site of lacrimal apparatus trauma as a result of a dog bite. Success was defined as lack of epiphora at the time of the last follow-up. Early surgical management of eyelid lacerations with lacrimal apparatus involvement had a success rate of 82%.

Eyelid lacerations due to dog bites have a greater prevalence of involvement of the lacrimal apparatus and especially the inferior canaliculus than lacerations due to other causes in children. Clinicians should have a high index of suspicion for lacrimal apparatus involvement and be prepared for surgical repair, if indicated.

As a result, the treatment options remain unsatisfactory and nonspecific. With the rapid advancement of diagnostic imaging techniques, imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI) are playing a more important role in IBD diagnosis and evaluation. Recent developments in nanotechnology utilize an interdisciplinary approach to specifically target molecular or cellular IBD pathological process thereby generating nanoparticles (NPs) with high specificity and diagnostic and/or therapeutic efficacy. Nano-based imaging, which incorporates nanotechnology and imaging modalities, may allow for the early detection of IBD, the monitoring of disease activity, and may be used to monitor the therapeutic response at cellular and/or molecular level. In this review, we highlight issues related to nano-based imaging and its application in IBD field.
Randomized, population-representative trials of clinical interventions are rare. Quasi-experiments have been used successfully to generate causal evidence on the cascade of HIV care in a broad range of real-world settings.

Quasi-experiments exploit exogenous, or quasi-random, variation occurring naturally in the world or because of an administrative rule or policy change to estimate causal effects. Well designed quasi-experiments have greater internal validity than typical observational research designs. At the same time, quasi-experiments may also have potential for greater external validity than experiments and can be implemented when randomized clinical trials are infeasible or unethical. Quasi-experimental studies have established the causal effects of HIV testing and initiation of antiretroviral therapy on health, economic outcomes and sexual behaviors, as well as indirect effects on other community members. Recent quasi-experiments have evaluated specific interventions to improve patient performance in the cascade of care, providing causal evidence to optimize clinical management of HIV.

Quasi-experiments have generated important data on the real-world impacts of HIV testing and treatment and on interventions to improve the cascade of care. With the growth in large-scale clinical and administrative data, quasi-experiments enable rigorous evaluation of policies implemented in real-world settings.

Health and demographic surveillance systems (HDSS), in conjunction with HIV treatment cohorts, have made important contributions to our understanding of the impact of HIV treatment and treatment-related interventions in sub-Saharan Africa. The purpose of this review is to describe and discuss innovations in data collection and data linkage that will create new opportunities to establish the impacts of HIV treatment, as well as policies affecting the treatment cascade, on population health and economic and social outcomes.

Novel approaches to routine collection of biomarkers, behavioural data, spatial data, social network information, migration events and mobile phone records can significantly strengthen the potential of HDSS to generate exposure and outcome data for causal analysis of HIV treatment impact and policies affecting the HIV treatment cascade. Additionally, by linking HDSS data to health service administration, education and welfare service records, researchers can substantially broaden opportunities to establish how HIV treatment affects health and economic outcomes when delivered through public sector health systems and at scale.
