#1
E King, R Patel, A Patel, L Addy
Dental implants are seen as a good option for replacing missing teeth. The success and survival rates for implants are very high. Concerns are developing about the problem of peri-implantitis. The reports of its prevalence vary but it is noted that the presence of periodontal disease is a risk factor. The issue of peri-implantitis was raised in the House of Lords in 2014. Complaints relating to implants is on the rise with the General Dental Council. Placement of implants in patients with periodontal disease is not a treatment that should be done without a full periodontal assessment and stabilisation of periodontal disease first...

Traumatic brain injury (TBI) in children can cause persisting cognitive and behavioral dysfunction and inevitably raises concerns about lost potential in these injured youths. Lateral fluid percussion injury (FPI) in weanling rats pathologically affects hippocampal NMDAR- and AMPAR-mediated glutamatergic neurotransmission subacutely, within the first post-injury week. FPI to weanling rats has also been shown to impair enriched-environment (EE) induced enhancement of Morris water maze (MWM) learning and memory in adulthood...

Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of pro-jection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results...

Relaxin (RLX) has demonstrated diverse pharmacological effects in various scientific and clinical studies. The emergence of porcine relaxin (pRLX) has raised concerns on the doping potential of pRLX. There have also been speculations in the horseracing industry on its covert use. In order to control the abuse of pRLX in equine sports, a method to detect pRLX effectively and to provide its unequivocal identification in equine biological samples is required. This paper reports on the detection and confirmation of pRLX in equine plasma by liquid chromatography/high resolution mass spectrometry...

The Bioartificial Renal Epithelial Cell System (BRECS), is a cell-based device to treat acute kidney injury through renal cell therapy from an extracorporeal circuit. To enable widespread implementation of cell therapy, the BRECS was designed to be cryopreserved as a complete device, cryostored, cryoshipped to an end-use site, thawed as a complete device, and employed in a therapeutic extracorporeal hemofiltration circuit. This strategy overcomes storage and distribution issues that have been previous barriers to cell therapy...

BACKGROUND: Cytochrome oxidase (COX) IV complex regulates energy production in mitochondria. Impaired COX gene expression is related to obesity and type 2 diabetes mellitus, but whether it is directly related to the incidence of cardiovascular events is unknown. We investigated whether COX gene expression in monocytes is predictive for cardiovascular events in coronary artery disease patients. To avoid monocyte isolation from fresh blood, we then aimed to validate our findings in monocyte-derived microvesicles isolated from plasma...

A collection of 75 modern skeletons from the Philippines has recently been created, and is being housed at the Archaeological Studies Program of the University of the Philippines, Diliman, Philippines. All individuals lived during the 20th century, and almost all died within the 21st century. These individuals were accessioned from exhumed and abandoned tombs at the Manila North Cemetery, and most have documented age and sex from tombstone inscriptions. This paper describes the first season of recovery and the collection's current demographic composition, with the future addition of more individuals to the collection expected to follow...

Microgastrinae wasps (Hymenoptera, Braconidae) from the city of Ottawa and its surroundings (a 50-km radius circle, ~7,800 km(2)) were studied based on 1,928 specimens collected between 1894 and 2010, and housed in the Canadian National Collection of Insects. A total of 158 species from 21 genera were identified, which is by far the highest number of species ever recorded for a locality in North America. An annotated checklist of species is provided. Choeras parasitellae (Bouché, 1834) and Pholetesor nanus (Reinhard, 1880) are recorded for the first time in the Nearctic (previously only known from the Palearctic region), Cotesia depressa (Viereck, 1912) is recorded for the first time in Canada (previously only known from the United States), and Cotesia hemileucae (Riley, 1881) and Protapanteles phlyctaeniae (Muesebeck, 1929) are recorded for the first time in the province of Ontario...

This paper presents a set of controlled laboratory experiments designed to develop a basis for understanding the relationship between microscopic and macroscopic properties of fine-grained sediments. Two samples of kaolinite platelets were selected for this study, and effects of sediment microstructure on geoacoustic properties are deduced from a comparison of the measured properties. To provide additional interpretation of the acoustic measurements, compressional and shear wave properties are compared to predicted values from sediment-acoustic models...

REVIEW
Andrzej Bozek
Recent studies suggest that allergic rhinitis is highly prevalent in the elderly population, but is underdiagnosed and undertreated. This review article briefly introduces allergic rhinitis in the elderly (epidemiology and pathophysiology) and identifies the main goals of treatment in these patients with respect to age-related physiological factors, comorbid conditions and polypharmacy. The primary focus of the article is a narrative review of the literature concerning the different types of treatment options in elderly patients aged 60+ years (pharmacological therapy and allergen-specific immunotherapy)...

Cationic materials have been reported as promising tools for targeting to mitochondria which are the "power houses" and "metabolic garbage keepers" of cells. However, their positive nature also restricts their in vivo application due to the quick clearance. Herein, we fabricated a nanohybrid consisting of the pH-responsive N-(2-hydroxypropyl)methacrylamide (HPMA) co-polymer (R-P) shells and positive mesoporous silica nanoparticle cores via electrostatic interaction. The anticancer drug, docetaxel (DTX), was encapsulated in the positive MSN cores (MSN-DTX)...

We report the calibration of the Orion High-Resolution X-ray (OHREX) imaging crystal spectrometer at the EBIT-I electron beam ion trap at Livermore. Two such instruments, dubbed OHREX-1 and OHREX-2, are fielded for plasma diagnostics at the Orion laser facility in the United Kingdom. The OHREX spectrometer can simultaneously house two spherically bent crystals with a radius of curvature of r = 67.2 cm. The focusing properties of the spectrometer allow both for larger distance to the source due to the increase in collected light and for observation of extended sources...

Y-chromosomal haplogroups are sets of ancestrally related paternal lineages, traditionally assigned by the use of Y-chromosomal single nucleotide polymorphism (Y-SNP) markers. An increasingly popular and a less labor-intensive alternative approach has been Y-chromosomal haplogroup assignment based on already available Y-STR data using a variety of different algorithms. In the present study, such in silico haplogroup assignments were made based on 23-loci Y-STR data for 100 unrelated male individuals from the Tuzla Canton, Bosnia and Herzegovina (B&H) using the following four different algorithms: Whit Athey's Haplogroup Predictor, Jim Cullen's World Haplogroup & Haplogroup-I Subclade Predictor, Vadim Urasin's YPredictor and the NevGen Y-DNA Haplogroup Predictor...

PURPOSE: To investigate the feasibility of three-dimensional (3D) dose measurements near thin high-Z materials placed in a water-like medium by using a polymer gel dosimeter (PGD) when the medium was irradiated with high energy photon beams. METHODS: PGD is potentially a useful tool for this application because it can record the dose around a small object made of a high-Z material in a continuous 3D medium. In this study, the authors manufactured a methacrylic acid-based normoxic PGD, nMAG...

BACKGROUND: We sought to determine whether basophil-allergen sensitivity could be transferred to donor basophils by passive IgE sensitisation in allergic rhinitis and anaphylactic Hymenoptera venom hypersensitivity. METHODS: We studied 15 wasp venom-, 19 grass pollen- and 2 house dust mite-allergic patients, 2 healthy donors, and 8 wasp venom-allergic donors. In all subjects, we first evaluated the initial basophil response to wasp venom, grass pollen, or house dust mite allergen...

BACKGROUND: The hyperglycemic clamp test, the gold standard of beta cell function, predicts impending type 1 diabetes in islet autoantibody-positive individuals, but the latter may benefit from less invasive function tests such as the proinsulin:C-peptide ratio (PI:C). The present study aims to optimize precision of PI:C measurements by automating a dual-label trefoil-type time-resolved fluorescence immunoassay (TT-TRFIA), and to compare its diagnostic performance for predicting type 1 diabetes with that of clamp-derived C-peptide release...

Genome-wide transcription factors (TFs) binding data has been extensively generated in the past few years, which poses a great challenge to data interpretation. Therefore, comprehensive and dedicated functional annotation databases for TF-DNA interaction are in great demands to manage, explore and utilize those invaluable data resources. Here, we constructed a platform 'TFBSbank' which houses the annotation of 1870 chromatin immunoprecipitation (ChIP) datasets of 585 TFs in five species (human, mouse, fly, worm and yeast)...
