Child growth stunting is common in low-income countries, possibly due to insufficient protein intakes. Most previous studies have concluded that children's protein intakes are adequate in relation to estimated requirements, but these studies did not consider issues of protein digestibility and effects of infection on dietary protein utilization. Using an alternative approach to assess the possible role of protein inadequacy in children's growth restriction, the results of 18 intervention trials in which supplementary protein or amino acids were provided to children ages 6-35 months and growth outcomes were reviewed...

The current left ventricular assist devices (LVADs) are limited by a highly invasive implantation procedure in a severely unstable group of advanced heart failure patients. Additionally, the current transcutaneous power drive line acts as a nidus for infection resulting in significant morbidity and mortality. In an effort to decrease this invasiveness and eliminate drive line complications, we have conceived a wireless miniaturized percutaneous LVAD, capable of being delivered endovascularly with a tether-free operation...

Domestic violence is a global public health issue. Midwives are ideally placed to screen for, and respond to, disclosure of domestic violence. Qualified midwives and midwifery students report a lack of preparedness and low levels of confidence in working with women who disclose domestic violence. This paper reports the findings from an education intervention designed to increase midwifery students' confidence in working with pregnant women who disclose domestic violence. An authentic practice video and associated interactive workshop was developed to bring the 'woman' into the classroom and to provide role-modelling of exemplary midwifery practice in screening for and responding to disclosure of domestic violence...

To date, existing tissue adhesives have various weak points in gluing kinetics and stability - particularly, in biocompatibility, which make most of them remain suboptimal for internal conditions. Herein, a novel mussel-inspired "BCD" tissue glue made of bovine serum albumin (BSA), citrate acid (CA) and dopamine was developed aiming at internal medical applications. BSA was employed as a natural and biocompatible macromolecular backbone; CA was introduced as a dual-functional intermediate to increase reactive carboxyl sites for engraftment of dopamine onto BSA backbone and also block the competing reactive amines from the proteinic backbone...

In the last decade, new methods of estimating global species richness have been developed and existing ones improved through the use of more appropriate statistical tools and new data. Taking the mean of most of these new estimates indicates that globally there are approximately 1.5 million, 5.5 million, and 7 million species of beetles, insects, and terrestrial arthropods, respectively. Previous estimates of 30 million species or more based on the host specificity of insects to plants now seem extremely unlikely...

Neural circuit development requires that synapses be formed between appropriate neurons. In addition, for a hierarchical network, successful development involves a sequencing of developmental events. It has been suggested that one mechanism that helps speed up development of proper connections is an early overproduction of synapses. Using a computational model of synapse development, such as adaptive synaptogenesis, it is possible to study such overproduction and its role in speeding up development; it is also possible to study other outcomes of synapse overproduction that are seemingly new to the literature...

Pediatric dentists are often the first ones to be consulted for the presence of an anterior cross bite in the primary dentition. The condition requires an early interception to avoid progressive dentoalveolar and skeletal changes. The management, however, poses unique challenges in terms of young age of the child, correct choice of appliance and unpredictability of the response to treatment due to inability to ascertain the inherent growth potential. It is very important therefore for the specialist, to be able to recognize the early signs of a developing class III malocclusion tendency and also know the basic details of successful management of such cases...

OBJECTIVE: Dental anxiety, fear and phobia have different etiology, response patterns, time courses, and intensities that justify a clear distinction between these constructs. Differentiation of dental anxiety, fear or phobia in practice is a critical prerequisite for developing and implementing effective treatment for children. The aim of this study was to investigate whether current researches in the pediatric dentistry appropriately discriminate the central construct of dental anxiety, fear and phobia...

A unique approach in mechanosynthesis, joining solid-state NMR spectroscopy, X-ray crystallography, and theoretical calculations, is employed for the first time to study the mechanism of the formation of the C-N amide bond using EDC·HCl as a coupling reagent. It has been proved that EDC·HCl, which in the crystal lattice exists exclusively in the cyclic form (X-ray data), easily undergoes transformation to a pseudocyclic stable intermediate in reaction with carboxylic acid forming a low-melt phase (differential scanning calorimetry, solid-state NMR)...

Tuberculosis (TB) is a chronic, potentially fatal disease caused by Mycobacterium tuberculosis (Mtb). The dihyrofolate reductase in Mtb (mt-DHFR) is believed to be an important drug target in anti-TB drug development. This enzyme contains a glycerol (GOL) binding site, which is assumed to be a useful site to improve the selectivity towards human dihyrofolate reductase (h-DHFR). There have been previous attempts to design drugs targeting the GOL binding site, but the designed compounds contain a hydrophilic group, which may prevent the compounds from crossing the cell wall of Mtb to function at the whole cell level...

We report the use of continuous electrical stimulation to assist with the preoperative placement of a thoracic epidural which was used to provide postoperative analgesia in a patient undergoing excision of a large scapular sarcoma. The size of the sarcoma and the surrounding area required to maintain a sterile surgical field necessitated that the epidural catheter be inserted several vertebral interspaces caudal to the level of desired catheter tip termination. The use of electrical stimulation allowed for sequential intercostal muscle stimulation during threading, which enabled the placement of the catheter tip at the appropriate spinal level to optimize analgesia...
