The relevance of right atrial pressure (RAP) as the back-pressure for venous return (QVR) and mean systemic filling pressure (MSFP) as up-stream pressure is controversial during dynamic changes of circulation. To examine the immediate response of QVR (sum of caval vein flows) to changes in RAP and pump function we used a closed chest, central cannulation, heart bypass porcine preparation (n=10) with veno-arterial extracorporeal membrane oxygenation (ECMO). MSFP was determined by clamping ECMO tubing with open or closed arterio-venous shunt at Euvolemia, Volume Expansion (9...

Protein modification by the small ubiquitin-like modifier (SUMO) plays important roles in genome maintenance. In Saccharomyces cerevisiae, proper regulation of sumoylation is known to be essential for viability in certain DNA repair mutants. Here we find the opposite result; proper regulation of sumoylation is lethal in certain DNA repair mutants. Yeast cells lacking the repair factors TDP1 and WSS1 are synthetically lethal due to their redundant roles in removing Top1-DNA covalent complexes (Top1ccs). A screen for suppressors of tdp1∆ wss1∆ synthetic lethality isolated mutations in genes known to control global sumoylation levels including ULP1, ULP2, SIZ2 and SLX5 The results suggest that alternative pathways of repair become available when sumoylation levels are altered...

BACKGROUND AND OBJECTIVES: Appendiceal neoplasms with extra-appendiceal spread may show different clinical patterns with pseudomyxoma peritonei (PMP) being one of them. We analyse the results in a series of patients treated in our centre. MATERIAL AND METHODS: Retrospective study of patients operated on for appendiceal peritoneal carcinomatosis from January 2012 to May 2015. RESULTS: Twenty-seven consecutive patients were included. Median age 63 years (26-73); 14 were men...

Malunion after forearm fractures are described to appear in 2% to 10% of cases. Reconstructive surgeries ensure adequate anatomical repositioning. Their importance derives from the fact that malunion can often lead to severe pain as well as deformities causing loss of function and aesthetic issues not only in the forearm, but also the wrist and elbow joint. In this paper a clinical case will be presented using a Patient Specific Instrument (PSI) as navigational aid for reconstructive surgery after malunion of a proximal ulnar fracture combined with allograft surgery of the radial head and radial condyle due to chronic traumatic radial head luxation (Monteggia fracture)...

Cytogenetics and European Leukemia Net (ELN) genetic classification predict patients at increased risk of relapse in acute myeloid leukemia (AML) except in the intermediate risk group for which further prognostic determinants are required. We have previously shown that Natural Killer (NK) cell defects in AML are predictors of poor overall survival (OS). This study aimins at validating NKp30, a receptor that mediates NK activation, as a prognostic biomarker for AML patients with intermediate prognosis.NKp30 expression was prospectively assessed at diagnosis on NK cells from peripheral blood by flow cytometry (N = 201 patients)...

Polydopamine is a bioinspired, versatile material that can adhere to bulk and nanoscale surfaces made of disparate materials to improve their physical and chemical properties in many applications. The typical methods to coat polydopamine on the nanoparticle substrates usually take several hours to a day. This work successfully applies a dispersion method to form a controllable, uniform coating on a nanoparticle surface within minutes. Using plasmonic Ag nanoparticles as a substrate, the coating thickness can be monitored using a spectroscopic method based on the extinction peak shifts of the Ag nanoparticles...

Unprotected sexual intercourse between persons residing in or traveling from regions with Zika virus transmission is a risk factor for infection. To model risk for infection after sexual intercourse, we inoculated rhesus and cynomolgus macaques with Zika virus by intravaginal or intrarectal routes. In macaques inoculated intravaginally, we detected viremia in 75% of macaques and virus RNA in 100%, followed by seroconversion. In macaques inoculated intrarectally, we detected viremia, virus RNA, or both, in 100% of both species, followed by seroconversion...

OBJECTIVE A recent survey has shown that caregivers of children with shunt-treated hydrocephalus frequently use social media networks for support and information gathering. The objective of this study is to describe and assess social media utilization among users interested in hydrocephalus. METHODS Publicly accessible accounts and videos dedicated to the topic of hydrocephalus were comprehensively searched across 3 social media platforms (Facebook, Twitter, and YouTube) throughout March 2016. Summary statistics were calculated on standard metrics of social media popularity...

Organometallic metal(arene) anticancer agents require ligand exchange for their anticancer activity and this is generally believed to confer low selectivity for potential cellular targets. However, using an integrated proteomics-based target-response profiling approach as a potent hypothesis-generating procedure, we found an unexpected target selectivity of a ruthenium(arene) pyridinecarbothioamide (plecstatin) for plectin, a scaffold protein and cytolinker, which was validated in a plectin knock-out model in vitro...

BACKGROUND: Patients with normal myocardial perfusion imaging (MPI) have a good prognosis. However, pre-clinical coronary and extracoronary atherosclerosis may exist in the absence of myocardial ischemia. METHODS: 154 Egyptian patients (mean age 53 years) underwent whole-body non-contrast CT following normal MPI. RESULTS: Atherosclerosis in the form of calcification was observed in ≥1 vascular bed in 115 of 154 (75%) patients. This included the iliofemoral (62%), abdominal aorta (53%), thoracic aorta (47%), coronary (47%), and carotid (25%) vascular beds...

The human thorax is commonly injured in motor vehicle crashes, and despite advancements in occupant safety rib fractures are highly prevalent. The objective of this study was to quantify the ability of gross and cross-sectional geometry, separately and in combination, to explain variation of human rib structural properties. One hundred and twenty-two whole mid-level ribs from 76 fresh post-mortem human subjects were tested in a dynamic frontal impact scenario. Structural properties (peak force and stiffness) were successfully predicted (p < 0...

Pornography has become increasingly accessible in the United States, and particularly for younger Americans. While some research considers how pornography use affects the sexual and psychological health of adolescents and emerging adults, sociologists have given little attention to how viewing pornography may shape young Americans' connection to key social and cultural institutions, like religion. This article examines whether viewing pornography may actually have a secularizing effect, reducing young Americans' personal religiosity over time...

BACKGROUND: Neoadjuvant radiotherapy (RT) and chemotherapy are applied to large, high-grade extremity soft tissue sarcomas to treat metastatic disease earlier and sterilize margins to perform R0 surgery. However, preoperative RT increases wound complication rates (rWC), delaying adjuvant chemotherapy or preventing it from being administered altogether. Hypofractionated neoadjuvant RT can be offered in this situation, concomitant to chemotherapy, allowing patients to receive chemotherapy as a preoperative treatment in less time with an acceptable rWC...

Light chain amyloidosis (AL) results in tissue deposition of misfolded proteins causing organ dysfunction. In an era of modern therapies such as bortezomib, reassessment of the benefit of autologous hematopoietic cell transplantation (AHCT) should be considered. This study compares the difference in outcomes between patients with AL receiving chemotherapy alone (CT) vs. AHCT. Seventy-four patients with AL were retrospectively analyzed. Two cohorts of patients were studied, those receiving CT (n=31) or AHCT (n=43)...
