Vladimir Despic, Mario Dejung, Falk Butter, Karla M Neugebauer
A decade ago, we believed that at least 300 RNA binding proteins (RBPs) were encoded in our genomes based on annotations of known or predicted RNA binding domains. Deciphering the roles of those RBPs in regulated gene expression was a vast frontier awaiting exploration. Since then, the field has developed a number of key tools that navigate the landscape of cellular RNA. These rely principally on UV crosslinking to create covalent bonds between RBPs and target RNAs in vivo, revealing not only target identities but also local binding sites upon RNA-Seq...

The aim of this case report was to demonstrate how the use of cone-beam computed tomographic (CBCT) imagery is beneficial when treating a tooth with an unusual anatomic variation. A 43-year-old female patient presented to our private practice after a referral from her general dentist. Endodontic therapy was previously initiated and unable to be completed because of suspicious anatomic anatomy. CBCT imagery confirmed the presence of a C-shaped root configuration and 3 canals within the tooth. Root canal treatment was completed successfully without complications...

Multiplex bead assays (MBAs) may provide a powerful integrated tool for monitoring, evaluation, and post-elimination surveillance of onchocerciasis and co-endemic diseases; however, the specificity and sensitivity of Onchocerca volvulus antigens have not been characterized within this context. An MBA was developed to evaluate three antigens (OV-16, OV-17, and OV-33) for onchocerciasis. Receiver operating characteristics (ROC) analyses were used to characterize antigen performance using a panel of 610 specimens: 109 O...

Strains of Toxoplasma gondii in Brazil are highly genetically diverse compared to strains from North America and Europe. Dogs are epidemiologically important because they act as sentinels for T. gondii infections in humans and are good indicators of environmental contamination. The aim of this study was to isolate and genetically characterize T. gondii strains from tissues of naturally infected Brazilian dogs. For this study, 21 blood samples were collected from dogs at the Zoonosis Control Centers of Ilhéus and Itabuna cities, Bahia, Brazil...

BACKGROUND: Venous thromboembolic events (VTEs) are common and potentially fatal complications in cancer patients, and they are responsible for the second most common cause of death. Low molecular weight heparin (LMWH) is the gold-standard treatment, but the costs involved limit its use, especially in developing countries. Recently, the oral anticoagulant rivaroxaban, which directly inhibits factor Xa, was approved for VTE treatment. METHODS: We conducted a retrospective analysis from January 2009 to February 2014 with patients who had cancer and VTE who were receiving rivaroxaban...

Label-free multispectral optoacoustic tomography (MSOT) has recently shown superior performance in visualizing the morphology of human vasculature, especially of smaller vessels, compared to ultrasonography. Herein, we extend these observations towards MSOT interrogation of macrovascular endothelial function. We employed a real-time handheld MSOT scanner to assess flow-mediated dilatation (FMD), a technique used to characterize endothelial function. A data processing scheme was developed to quantify the dimensions and diameter changes of arteries in humans and determine wall distensibility parameters...

Maternal RhD alloimmunization is an inflammatory response against protein antigens in fetal red blood cells (RBC). However, not all women become alloimmunized when exposed to RhD(+) fetal RBC. Thus, this study aimed to evaluate levels of inflammatory chemokines in RhD(-) pregnant women with erythrocyte alloimmunization. CXCL8, CXCL9, CCL5, and CXCL10 levels were determined from cell culture supernatants by flow cytometry in 46 (30 non-alloimmunized RhD(-) and 16 previously alloimmunized RhD(-)) pregnant women...

BACKGROUND: There is increasing evidence that azithromycin 1 g is driving the emergence of macrolide resistance in Mycoplasma genitalium worldwide. We undertook a meta-analysis of M. genitalium treatment studies using azithromycin 1 g single dose and azithromycin 500 mg on day 1 then 250 mg daily for 4 days (5-day regimen) to determine rates of treatment failure and resistance in both regimens. METHODS: The online databases PubMed and Medline were searched using terms "Mycoplasma genitalium", "macrolide" or "azithromycin" and "resistance" up to April 2016...

Although Konkle, Brady, Alvarez, and Oliva (2010, Journal of Experimental Psychology: General, 139(3), 558) claim that visual long-term memory (VLTM) is organized on underlying conceptual, not perceptual, information, visual memory results from visual search tasks are not well explained by this theory. We hypothesized that when viewing an object, any task-relevant visual information is critical to the organizational structure of VLTM. In two experiments, we examined the organization of VLTM by measuring the amount of retroactive interference created by objects possessing different combinations of task-relevant features...

BACKGROUND: Neonatal aortic arch reconstruction, typically performed with deep hypothermia and selective cerebral perfusion, leaves splanchnic organ protection dependent on hypothermia alone. A simplified method of direct in-field descending aortic perfusion during neonatal arch reconstruction permits the avoidance of deep hypothermia. We hypothesize that direct splanchnic perfusion at mild hypothermia provides improved or equivalent safety compared with deep hypothermia and may contribute to postoperative extracardiac organ recovery...

BACKGROUND: Preoperative low-dose whole-body irradiation (IRR) with 1.5 and 7 Gy thymic IRR of the recipient, combined with a perioperative donor splenocyte infusion lead to reliable donor specific peripheral tolerance in our allogeneic porcine lung transplantation model. To reduce the toxicity of this preconditioning regime, modifications of the IRR protocol and their impact on allograft survival were assessed. METHODS: Left-sided single lung transplantation from major histocompatibility complex and sex mismatched donors was performed in 14 adult female minipigs...

This paper examines fruit and vegetable intake (FVI) in low-income households that participated in a cost-offset (CO), or 50% subsidized, community-supported agriculture (CSA) program. CSA customers paid farms upfront for a share of the harvest, and received produce weekly throughout the growing season. A cohort of adults and children 2-12 y in a summer CO-CSA were surveyed online twice: August 2015 (n = 41) and February 2016 (n = 23). FVI was measured by the National Cancer Institute's (NCI) Fruit and Vegetable Screener (FVS) and an inventory of locally grown fruits and vegetables...

Ionotropic glutamate receptors (iGluRs) are involved in most of the fast excitatory synaptic transmission in the central nervous system. These receptors are important for learning and memory formation, but are also involved in the development of diseases such as Alzheimer's disease, epilepsy and depression. In order to understand the function of different types of iGluRs, selective agonists are invaluable as pharmacological tool compounds. Here, we report binding affinities of two bicyclic, conformationally restricted analogues of glutamate (CIP-AS and LM-12b) at AMPA (GluA2 and GluA3) and kainate receptor subunits (GluK1-3 and GluK5)...

Pesticide intoxication is a major public health concern, and unfortunately there is not an effective treatment for severe organophosphorus pesticide intoxication. In this work, a non-immunogenic enzymatic bioconjugate based on cytochrome P450 was assayed for organophosphorus pesticide transformation. Enzyme therapy is an alternative approach to inactivate pesticides in the bloodstream, transforming them into less toxic metabolites. A variant of cytochrome P450 (CYPBM3 F87A) from Bacillus megaterium was chemically modified with polyethylene glycol...
