BACKGROUND: Distinguishing sessile serrated adenomas/polyp (SSA/P), a subset of serrated polyps, from hyperplastic polyps (HPs) remains a challenge and has surveillance implications. Our goal was to identify clinical and pathologic factors associated with serrated polyps originally read as HPs being reassessed as SSA/Ps versus confirmed as HPs. METHODS: Data were collected from consecutive patients with a right-sided HP and a corresponding comparison group with conventional adenomas between 1993 and 2003...

We report the results of an investigation into a fatal case of hantavirus pulmonary syndrome (HPS) in Rio de Janeiro State, Brazil, where the disease had not been reported previous to 2015. Following the notification of an HPS case, serum samples were collected from the household members and work contacts of the HPS patient and tested for antibody to hantaviruses. Seroprevalence of 22% (10/45) was indicated for hantavirus out of 45 human samples tested. Blood and tissue samples were collected from 72 rodents during fieldwork to evaluate the prevalence of hantavirus infection, by using enzyme-linked immunosorbent assay IgG, and to characterize the rodent hantavirus reservoir(s), by reverse transcription polymerase chain reaction and sequencing...

BACKGROUND: Cerebral hyperperfusion syndrome (HPS) is a potentially life-threatening complication following carotid artery stenting (CAS) and carotid endoarterectomy (CEA). Early prediction and treatment of patients at risk for HPS are required in patients undergoing CAS because HPS occurs significantly earlier after CAS than CEA. Near-infrared spectroscopy (NIRS) is often used for monitoring, and indocyanine green (ICG) kinetics by NIRS (ICG-NIRS) can detect reductions in cerebral perfusion in patients with acute stroke...

Advancements in light-emitting diode (LED) technology have made them a viable alternative to current lighting systems for both sole and supplemental lighting requirements. Understanding how wavelength specific LED lighting can affect plants is thus an area of great interest. Much research is available on the wavelength specific responses of leaves from multiple crops when exposed to long-term wavelength specific lighting. However, leaf measurements do not always extrapolate linearly to the complexities which are found within a whole plant canopy, namely mutual shading and leaves of different ages...

GOALS: Over the past twenty years, the existence of oral Helicobacter pylori (H. pylori) infection has been controversial and is still disputed. It proposes that living H. pylori do not exist in the oral cavity. However, the progressive loss of efficacy of standard eradication therapies has made the treatment of H. pylori more challenging than ever due to oral H. pylori infection. We conducted a study to explore the existence of oral H. pylori infection among 4321 adults. PROCEDURES: A total 4321 adults (age range, 20-89 years old) comprising 2849 men and 1472 women were recruited by annual physical exam and evaluated using the saliva H...

100K is an important scaffolding protein of adenoviruses including fowl adenovirus serotype 4 (FAdV-4) that causes inclusion body hepatitis-hydropericardium syndrome (IBH-HPS) in poultry. 100K carries out the trimerization of the major capsid hexon protein of the virus for the generation of new virions inside the target host cells. Despite its critical role for FAdV-4, no structural study, in particular, has been conducted so far. Here, the overexpression of soluble 100K protein was successfully carried out in E...

P34 probable thiol protease (P34) and Gly m Bd 30K (30K) show high relationship with the protease of 24 kDa oleosin of soybean oil bodies. In this study, 9 day germinated soybean was used to separate bioprocessed P34 (P32) from bioprocessed 30K (28K). Interestingly, P32 existed as dimer, whereas 28K existed as monomer; a P32-rich sample had proteolytic activity and high cleavage site specificity (Lys-Thr of 24 kDa oleosin), whereas a 28K-rich sample showed low proteolytic activity; the P32-rich sample contained one thiol protease...

Due to the controversy regarding the criterion for diagnosing heel pad (HP) pathology based on evaluating the state of the heel pad stiffness (HPS), this paper intended to apply modeling to understand the influence of the HPS on the mechanical responses of the HP at heelstrike during locomotion, in an attempt to investigate the optimum HPS in terms of the health-related mechanical responses. Two different models, a finite element model and a classical mechanical model, were used to simulate the mechanical responses (force loading and deformation) experienced by the HP at heelstrike...

A diploid genome is necessary for normal mammalian development, thus haploid parthenogenetic embryos undergo frequent self-diploidization during preimplantation development; however, the underlying mechanism is unclear. In this study, time-lapse recording revealed that human haploid parthenotes (HPs) undergo self-diploidization via failed cytokinesis (FC) and endomitosis (EM). The frequencies of FC/EM were significantly higher in HPs than in normal fertilized embryos (26.3% vs. 1.6%, P < 0.01; 19.7% vs...

BACKGROUND: The sickest-first principle in donor-liver allocation can be implemented by allocating organs to cirrhotic patients with the highest Model of End-stage Liver Disease (MELD) scores. For patients with other risk factors, standard (SE) and non-standard exceptions (NSE) have been developed. We investigated whether this system of matched MELD scores achieves similar outcome on the liver transplant waiting-list for various diagnostic groups in Eurotransplant (ET) countries with MELD-based individual allocation (Belgium, The Netherlands and Germany)...

BACKGROUND AND AIMS: One central factor in hepatopulmonary syndrome (HPS) pathogenesis is intravascular accumulation of activated macrophages in small pulmonary arteries. However, molecular mechanism underlying the macrophage accumulation in HPS is unknown. In this study, we aimed to explore whether elevated COX-2 induces the Bone morphogenic protein-2 (BMP-2)/Crossveinless-2 (CV-2) imbalance and then activation of BMP signaling pathway promotes the macrophage accumulation in Common Bile Duct Ligation (CBDL) rat lung...

Hermansky-Pudlak syndrome (HPS), first described in 1959, is a rare form of syndromic oculocutaneous albinism associated with bleeding diathesis and in some cases pulmonary fibrosis and granulomatous colitis. All 10 HPS types are caused by defects in vesicle trafficking of lysosomes-related organelles (LRO) proteins. The HPS5 protein associates with HPS3 and HPS6 to form the Biogenesis of Lysosome-related Organelles Complex-2 (BLOC-2). Here we report the clinical and genetic data of 11 HPS-5 patients analyzed in our laboratory...

Providing clinical opportunities for students to gain experience in managing cardiac dysrhythmias is a challenge for nursing faculty. High-risk experiences are often not available for all students or are too life-threatening to entrust to students. Faculty shortages and increasing enrollments add to declines in clinical opportunities. The use of human patient simulation (HPS) has added opportunities to experience high-risk, low-frequency clinical situations. HPS may be employed in the classroom setting to teach content related to dysrhythmia treatments...
