BACKGROUND: Orthodontic treatment involves using fixed or removable appliances (dental braces) to correct the positions of teeth. The success of a fixed appliance depends partly on the metal attachments (brackets and bands) being glued to the teeth so that they do not become detached during treatment. Brackets (metal squares) are usually attached to teeth other than molars, where bands (metal rings that go round each tooth) are more commonly used. Orthodontic tubes (stainless steel tubes that allow wires to pass through them), are typically welded to bands but they may also be glued directly (bonded) to molars...

SETTING: A third of the world's population has latent tuberculous infection (LTBI). Current TB diagnostics used in developing countries are ineffective and are unable to distinguish LTBI from active TB. Identifying biomarkers that could aid in the early detection of TB and in distinguishing TB states could be a major breakthrough in global TB control. OBJECTIVE: To identify potential immune biomarkers to distinguish active TB from LTBI. DESIGN: A cross-sectional study was conducted among 19 active TB patients, 8 TB-negative individuals (controls) and 16 LTBI non-human immunodeficiency virus infected individuals in Nairobi, Kenya...

In this study, strain-resolved metagenomics was used to solve a mystery. A 6.4-Mbp complete closed genome was recovered from a soil metagenome and found to be astonishingly similar to that of Delftia acidovorans SPH-1, which was isolated in Germany a decade ago. It was suspected that this organism was not native to the soil sample because it lacked the diversity that is characteristic of other soil organisms; this suspicion was confirmed when PCR testing failed to detect the bacterium in the original soil samples...

Predictive models are valuable tools for assessing food safety. Existing thermal inactivation models for Salmonella and ground chicken do not provide predictions above 71°C, which is below the recommended final cooked temperature of 73.9°C for chicken. They also do not predict when all Salmonella are eliminated without extrapolating beyond the data used to develop them. Thus, a study was undertaken to develop a model for thermal inactivation of Salmonella to elimination in ground chicken at temperatures above those of existing models...

BACKGROUND: The influence of blood collection devices on laboratory tests is often overlooked. We have discussed here how blood collection materials and devices can alter haematological test results, with an emphasis on blood collection tube (BCT) additives. We have compared K2 & K3-EDTA vacuum tubes of same manufacturer IMPROVACUTER (®) for CBC analysis. METHODS: Blood was collected in both tubes simultaneously. Samples were analysed immediately after collection (<15 minutes) and after 4 hours by MEK-6318J/K Haematology Analyzer...

INTRODUCTION: Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. AIM: To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain...

Fluorogenic probes targeting G-quadruplex structures have emerged as the promising toolkit for functional research of G-quadruplex and biosensor development. However, their biosensing applications are still largely limited in in-tube detection. Herein, we proposed a fluorescent bioimaging method based on enzyme-generated G-quadruplexes for detecting apoptotic cells at the cell and tissue level, namely, terminal deoxynucleotidyl transferase (TdT)-activated de novo G-quadruplex synthesis (TAGS) assay. The detection target is genomic DNA fragmentation, a biochemical hallmark of apoptosis...

The aim of the current study is to develop a sensitive solid-phase microextraction (SPME) device for direct and rapid analysis of untreated complex matrixes (i.e., single drop of the samples, V ≤ 2 μL). A thin layer of a biocompatible nanostructured polypyrrole (PPy) was electrochemically deposited inside a medical grade spinal needle, minimizing the matrix effect. Microsampling was facilitated by loading the sample inside the in-tube SPME device (withdraw of sample via plunger), where extraction was performed under static conditions...

In this investigation, the mobility of system eigenpeaks in capillary electrophoresis (CE) was experimentally found to decrease when the background electrolyte (BGE) contained higher percentages of acetonitrile. In order to explain this observation, the effects of changes in the pH and ionic strength of the BGE on the pKa and actual mobility of each constituent in the system were determined, and the results evaluated in terms of their theoretical basis. Utilizing the derived values of each of these parameters, the software Peakmaster was then applied to simulate the eigenpeak mobility...

PURPOSE: Fecal incontinence is a socially debilitating problem for many children. We hypothesized that in selected patients with medically-refractory encopresis, placement of an appendicostomy or cecostomy tube for administration of antegrade continence enemas (ACE) would improve quality of life (QOL). METHODS: We reviewed all patients with encopresis who underwent appendicostomy or cecostomy placement from 2003 to 2014 at our institution. We contacted subjects' parents by phone and administered 3 surveys: a survey reflecting current stooling habits, a disease-specific QOL survey, and the PedsQL™ QOL survey...

A new multiplex PCR test was designed to detect Mycobacterium chelonae, Mycobacterium abscessus group, and Mycobacterium fortuitum complex on the BD MAX System. A total of 197 clinical samples previously submitted for mycobacterial culture were tested using the new protocol. Samples were first treated with proteinase K, and then each sample was inoculated into the BD MAX Sample Buffer Tube. Extraction and multiplex PCR were performed by the BD MAX System, using the BD MAX ExK TNA-3 extraction kit and BD TNA Master Mix, along with specific in-house designed primers and probes for each target...

The protozoan Trypanosoma cruzi is the causative agent of Chagas disease, a major public health problem in Latin America. This parasite has a complex population structure comprised by six or seven major evolutionary lineages (discrete typing units or DTUs) TcI-TcVI and TcBat, some of which have apparently resulted from ancient hybridization events. Because of the existence of significant biological differences between these lineages, strain characterization methods have been essential to study T. cruzi in its different vectors and hosts...

Electromagnetic-guided placement of nasoenteral feeding tubes by nurses is an alternative to endoscopic placement by gastroenterologists. During placement, the electromagnetic signal that is emitted by the tip of the guidewire enables visualisation of the position of the tube on a portable monitor. The procedure can be performed by a trained endoscopy nurse at the bedside of the patient. This could have logistic advantages, as the patient transport is not necessary and confirmation of the position of the tube by an abdominal X-ray is not required...

Surgical resection of colorectal cancer liver metastases (CLM) can be curative, yet 80% of patients are unsuitable for this treatment. As angiogenesis is a determinant of CLM progression we isolated endothelial cells from CLM and sought a mechanism which is upregulated, essential for angiogenic properties of these cells and relevant to emerging therapeutic options. Matched CLM endothelial cells (CLMECs) and endothelial cells of normal adjacent liver (LiECs) were superficially similar but transcriptome sequencing revealed molecular differences, one of which was unexpected upregulation and functional significance of the checkpoint kinase WEE1...

OBJECTIVE: Reduced skin flap survival due to ischemia is a serious concern during reconstructive cosmetic surgery. The absence of vascular endothelial growth factor (VEGF) and its receptors during ischemia may lead to flap failure. We identified Pellino-1 (Peli1), a 46-kDa protein, as a proangiogenic molecule and is directly regulated by VEGF. Therefore, we hypothesized that Peli1 acts downstream of Flk-1/VEGFR2 and aids in skin flap survival during ischemia. METHODS: Scratch and matrigel assays were performed to observe cell proliferation, migration and tube formation in vitro...
