Modulation-doped III-V semiconductor nanowire (NW) heterostructures have recently emerged as promising candidates to host high-mobility electron channels for future high-frequency, low-energy transistor technologies. The one-dimensional geometry of NWs also makes them attractive for studying quantum confinement effects. Here, we report correlated investigations into the discrete electronic sub-band structure of confined electrons in the channel of Si delta-doped GaAs/AlAs core-superlattice NW heterostructures and the associated signatures in low-temperature transport...

REVIEW
Lynette Lincoln, Sunil S More
Invertase or β-D-fructofuranoside fructohydrolase (EC 3.2.1.26) was one of the foremost enzyme biocatalysts and established the primary concepts of most enzyme-kinetic principles. Invertases are glycoside hydrolases and occur mostly in microorganisms. Among microbial strains, for many decades yeast species have been extensively researched for invertase production, characterization, and applications in industries. Besides, limited literature is available on invertases from bacterial strains. The enzymic and molecular biological reports from bacterial invertases are scarce...

BACKGROUND: RBM10 is an RNA binding protein involved in message stabilization and alternative splicing regulation. The objective of the research described herein was to identify novel targets of RBM10-regulated splicing. To accomplish this, we downregulated RBM10 in human cell lines, using small interfering RNAs, then monitored alternative splicing, using a reverse transcription-PCR screening platform. RESULTS: RBM10 knockdown (KD) provoked alterations in splicing events in 10-20% of the pre-mRNAs, most of which had not been previously identified as RBM10 targets...

A clash of values has been identified between those who assert that:1. all childhood injuries, regardless of origin, are inherently undesirable and should be prevented and;2. those who believe that some measure of injury to children is an acceptable compromise for the physical benefits associated with physical activity and the development of abilities to appraise and deal with risks.A debate regarding whether the tackles and collisions permitted in schools' rugby represent acceptable risks, and what steps should be taken if they do not, exemplifies the issue...

While the direct physical impact on seabed biota is well understood, no studies have defined thresholds to inform an ecosystem-based approach to managing fishing impacts. We addressed this knowledge gap using a large-scale experiment that created a controlled gradient of fishing intensity and assessed the immediate impacts and short-term recovery. We observed a mosaic of taxon-specific responses at various thresholds. The lowest threshold of significant lasting impact occurred between 1 and 3 times fished and elicited a decrease in abundance of 39 to 70% for some sessile epifaunal organisms (cnidarians, bryozoans)...

To assess the change in the size of the eastern North American monarch butterfly summer population, studies have used long-term data sets of counts of adult butterflies or eggs per milkweed stem. Despite the observed decline in the monarch population as measured at overwintering sites in Mexico, these studies found no decline in summer counts in the Midwest, the core of the summer breeding range, leading to a suggestion that the cause of the monarch population decline is not the loss of Midwest agricultural milkweeds but increased mortality during the fall migration...

Unimpaired near vision is crucial in dentistry, but appropriate visual tests at dental working distance are not publicly available. The aim of this study was to validate a novel visual triage test for dentists that is easy to use and freely available. The near visual acuity at 300 mm of 106 dental professionals (aged 21-65 years) was assessed with 1) a validated near visual test for scientific purposes miniaturized on a microfilm; 2) an experimental test using a US $5 bill, in which the first five words of each line in the Lincoln Memorial frieze had to be read under a dental operating light...

OBJECTIVES: Agriculture is one of the most hazardous industries in the United States. Within agriculture, livestock handling is particularly dangerous. While injury and fatality rates for bison handlers have not been reported, workers in many of the newly established tribal bison herds have limited safety training and animal handling experience, making this a vulnerable workforce. Veterinarians and herd managers, working with tribal bison herds, recognized the need for improvement in the working environment and for worker safety training...

Despite the new World Health Organization data remind us how syphilis is a disease which affects both sexes equally, this pathology has always been mainly considered a male disease. While several famous men are known to be affected by syphilis, there are very few women affected by this pathology of which we have historical records. Through the lives of Mary Todd Lincoln, Catherine of Aragon, Karen Blixen and Florence Foster Jenkins, this article would like to grant dignity to all the women who contracted syphilis in the wrong historical era where, for a woman, admitting to contracting it was shameful...

BACKGROUND: Maternal and infant mortality remains a huge public health problem in developing countries. One of the strategies to minimise the risks of both maternal and infant mortality is access to and utilisation of antenatal care (ANC) services. AIM: This study aimed to investigate the accessibility factors that influence the use of ANC services in Mangwe district.

Many wound care centers (WCCs) provide a specialized level of care using various wound care therapies and are managed by quali ed healthcare professionals (QHPs) from di erent specialty backgrounds such as family medicine, podiatry, and plastic surgery. However, these QHPs are sometimes challenged by reimbursement issues, limited therapy and dressing options, reduced access to multidisciplinary team members, and cost-driven factors unique to WCCs. To help address these issues, a meeting was convened by an expert panel of WCC physicians to discuss best practices for treating complex patients in a WCC...

The field of morphometrics is developing quickly. Recent advances have enabled geometric techniques to be applied to many zoological problems, particularly those involving epidemiologically-relevant mosquitoes. Herein, we briefly introduce geometric morphometric (GM) techniques and then review selected groups of mosquitoes (Culicidae) to which those techniques have been applied. In most of the reviewed cases, GM was capable of satisfactorily discriminating among the tested groups primarily when the studies considered differences within and among species, sexual dimorphism, treatments and the separation of laboratory strains...

Background: One of the most important aetiologies of cervical cancer is Human Papillomavirus (HPV) infection. While vaccination is an effective way in preventing high risk HPV infection, HPV vaccine uptake rate in Hong Kong has been low. Considering the proven effectiveness of HPV vaccination and the low vaccination uptake rate in Hong Kong, this study was conducted to compare the knowledge, attitude and practice towards HPV vaccination for cervical cancer prevention between medical and non-medical students in the University of Hong Kong...

OBJECTIVE: This study examined the role of stress in the association among physical activity, obesity, and depression among women. The extent to which physical activity moderated these relationships was also examined.

Foreign bodies in the spine are most commonly traumatic and managed in an acute setting. A few case reports describe foreign bodies resulting in delayed neurologic dysfunction, most commonly iatrogenic or from penetrating injury. We present a 30-year old man with lower extremity weakness from an intradural extramedullary foreign body granuloma secondary to a thorn, which was initially thought to represent an aggressive malignant process with intra and extramedullary involvement on MR. Postoperatively, the patient endorsed a causative trauma several years prior...

BACKGROUND: A key step in cancer genome analysis is the identification of somatic mutations in the tumor. This is typically done by comparing the genome of the tumor to the reference genome sequence derived from a normal tissue taken from the same donor. However, there are a variety of common scenarios in which matched normal tissue is not available for comparison. RESULTS: In this work, we describe an algorithm to distinguish somatic single nucleotide variants (SNVs) in next-generation sequencing data from germline polymorphisms in the absence of normal samples using a machine learning approach...
