#1
Nurettin Sahiner, Sahin Demirci
Polyethylene imine (PEI) microgels prepared via micro emulsion polymerization technique were treated with 1,3-propane sultone to obtained betainized PEI (b-PEI) microgels. The betainization reaction generated zwitterions on PEI microgel that are positive charges from quarternized amine groups of PEI, and the newly formed negative charges from SO3(-) groups from the modifying agent, 1,3-propane sultone offered interesting properties. The smaller size of b-PEI microgels that are obtained by simple filtration were increased with betainization from 512±14 to 1114±86nm...

AIM: An increasing number of failing automated external defibrillators (AEDs) is reported: AEDs not giving a shock or other malfunction. We assessed to what extent AEDs are 'failing' and whether this had a device-related or operator-related cause. METHODS: We studied analysis periods from AEDs used between January 2012 and December 2014. For each analysis period we assessed the correctness of the (no)-shock advice (sensitivity/specificity) and reasons for an incorrect (no)-shock advice...

Pulmonary hypertension (PH) is a strong predictor of mortality in patients with heart failure (HF). However, the relationship between PH, through echocardiographic pulmonary artery pressure (PASP) estimation, and the risk of HF rehospitalizations remains unclear. METHODS: We prospectively included 2343 consecutive patients discharged for acute heart failure (AHF). PH was estimated by echocardiography through PASP determination during the index admission. Patients were categorized as follows across PASP: non-measurable, normal (≤35mmHg), mild (36-45mmHg), moderate (46-60mmHg), or severe PH (>60mmHg)...

Damask rose (Rosa damascena Mill.) is one of the most high-value essential oil-bearing plants in the world. However, the flower yield and quality of essential oil of R. damascena are largely influenced by the pruning practices and balanced supply of plant nutrition. The objective of this study was to test the hypothesis whether the pruning system and foliar fertilization of MgSO4 would influence the flower yield, growth and secondary metabolites profile of R. damascena. A field experiment of 10 treatment combinations comprising two pruning systems (complete and partial) and five levels of MgSO4 (water spray, MgSO4 @ 5...

The association between dietary vitamin K intake and the risk of fractures is controversial. Therefore we perform a meta-analysis of cohort or nested case-control studies to investigate the relationship between dietary vitamin K intake and the risk of fractures. A comprehensive search of PubMed and EMBASE (to July 11, 2016) was performed to identify cohort or nested case-control studies providing quantitative estimates between dietary vitamin K intake and the risk of fractures. Summary relative risk (RRs) with corresponding 95% confidence intervals (CIs) were pooled by using a random-effects model...

OBJECTIVES: Dicarbonyl stress and high concentrations of advanced glycation endproducts (AGEs) relate to an elevated risk for cardiovascular diseases (CVD). Exercise training lowers the risk for future CVD. We tested the hypothesis that lifelong endurance athletes have lower dicarbonyl stress and AGEs compared to sedentary controls and that these differences relate to a better cardiovascular health profile. DESIGN: Cross-sectional study. METHODS: We included 18 lifelong endurance athletes (ATH, 61±7years) and 18 sedentary controls (SED, 58±7years) and measured circulating glyoxal (GO), methylglyoxal (MGO) and 3-deoxyglucosone (3DG) as markers of dicarbonyl stress...

BACKGROUND: The standard treatment strategy of mass drug administration with ivermectin plus albendazole for lymphatic filariasis cannot be applied in central Africa, because of the risk of serious adverse events in people with high Loa loa microfilaraemia. Thus, alternative strategies are needed. We investigated one such alternative strategy for mass drug administration for elimination of lymphatic filariasis and soil-transmitted helminth infections in Republic of the Congo. METHODS: In 2012, we started a 3 year community trial of biannual mass administration of albendazole in a village in Republic of the Congo...

BACKGROUND: Periarticular anesthesia (PAI) with liposomal bupivacaine (LB) and femoral nerve block (FNB) were 2 common type of pain management after total knee arthroplasty (TKA). There is no consensus about PAI with LB shows better clinical outcome than FNB. Thus, we performed a systematic review and meta-analysis to compare the efficacy and safety of PAI with LB and FNB for patients prepared for TKA. METHODS: Randomized controlled trials (RCTs) and non-RCTs from PubMed (1966-2017...

BACKGROUND: The 2014-15 Ebola virus disease (EVD) epidemic strained health systems in west Africa already overburdened with other diseases, including malaria. Because EVD and malaria can be difficult to distinguish clinically, and rapid testing was not available in many Ebola Treatment Units (ETUs), guidelines recommended empirical malaria treatment. Little is known, however, about the prevalence and characteristics of patients entering an ETU who were infected with malaria parasites, either alone or concurrently with Ebola virus...

BACKGROUND: Previous reports indicate that treating patients with lupus (SLE) at or close to the time of diagnosis successfully without using any, or minimal, corticosteroids by using B-cell depletion (BCD) is possible in the short-term. It is not however known whether using BCD is as effective or reduces corticosteroid use in the long-term. We report the long-term (up to 7 years) use of BCD with respect to its steroid-saving capacity and clinical effectiveness in newly diagnosed SLE...

BACKGROUND: Metabolic syndrome (Met-S) has a robust concurrent association with depression. A small, methodologically limited literature suggests that Met-S and depression are reciprocally related over time, an association that could contribute to their overlapping influences on morbidity and mortality in cardiovascular disease, diabetes, and cancer. PURPOSE: Using a refined approach to the measurement of Met-S as a continuous latent variable comprising continuous components, this study tested the prospective associations between Met-S and depression...
