Ion-Sensitive Field-Effect Transistors With Micropillared Gates for Measuring Cell Ion Exchange at Molecular Levels

The detection of small concentrations of cancer cells before cancer takes over the primary organ completely, or metastasizes to other areas of the body is important for early screening of cancer. One approach to address cancer early screening is through cell ion exchange bioelectricity, which characterizes voltage potential in non-neuronal cells to regulate shape changing, proliferation, differentiation, migration, and cancer formation. Herein, novel ion-sensitive field-effective transistor (ISFET) modality is shown to measure cell behavior during the change of cell properties at molecular levels. ISFETs produce low resistance signals and consume low power. The small size of ISFETs enables miniature diagnosis devices that can be affordably fabricated in a massive array format. A large number of cells can be measured in parallel. Therefore, ISFET allows the combination of low sample requirements and prompt response. ISFETs have the ability to measure the effect of ions from complex biological samples and can be used as affordable point of care devices

If current inhibitor ivabradine in patients with idiopathic dilated cardiomyopathy: Impact on the exercise tolerance and quality of life

Background: Evidence supported a beneficial effect of ivabradine on clinical outcome of patients with systolic heart failure, and a sinus heart rate (HR) ≥ 70 bpm. We explored the effect of ivabradine, vs. placebo, added to evidence-based treatment on exercise tolerance and quality of life in patients with idiopathic dilated cardiomyopathy. Methods: We enrolled 43 consecutive patients with dilated cardiomyopathy of no apparent cause, a left ventricular ejection fraction (LVEF) < 40%, New York Heart Association class ≥ II, sinus HR ≥ 70 bpm, and background evidence-based anti-failure medications. Ischemic heart disease was ruled out. Patients were randomized (1:1) to receive ivabradine or placebo. Ivabradine was titrated up gradually till 7.5 mg twice daily, or a HR < 60 bpm, and continued for 3 months. Symptom-limited exercise tolerance test was performed, and quality of life was assessed by the Minnesota Living With Heart Failure Questionnaire at 0, and 3 months. Results: Forty-three patients were randomized to ivabradine (n = 20), or placebo (n = 23). Mean age was 50.8 ± 14.5 years (53.5% males). Mean HR was 85 ± 12 bpm, and mean LVEF was 32 ± 6%. Mean dose of carvedilol was 31.2% of the target dose. Baseline HR, blood pressure, exercise tolerance, Minnesota questionnaire score, and left ventricular systolic function were comparable between the two groups (p > 0.05 for all). At 3 months, mean dose of ivabradine was 6.8 mg bid. Ivabradine-treated patients had a lower HR, and improved left ventricular dimensions and systolic function, versus placebo-treated ones (p < 0.05 for all). HR dropped by a mean of 14 bpm in the ivabradine group, corrected for placebo. Both exercise tolerance, and Minnesota questionnaire score were better in the ivabradine group (p < 0.05 both). Ivabradine was well-tolerated. Conclusions: In symptomatic patients with idiopathic dilated cardiomyopathy, the addition of ivabradine, vs. placebo, to evidence-based treatment, reduced HR, and improved functional capacity, at short-term follow-up

Magnetic tension and gravitational collapse

The gravitational collapse of a magnetised medium is investigated by studying qualitatively the convergence of a timelike family of non-geodesic worldlines in the presence of a magnetic field. Focusing on the field's tension we illustrate how the winding of the magnetic forcelines due to the fluid's rotation assists the collapse, while shear-like distortions in the distribution of the field's gradients resist contraction. We also show that the relativistic coupling between magnetism and geometry, together with the tension properties of the field, lead to a magneto-curvature stress that opposes the collapse. This tension stress grows stronger with increasing curvature distortion, which means that it could potentially dominate over the gravitational pull of the matter. If this happens, a converging family of non-geodesic lines can be prevented from focusing without violating the standard energy conditions.Comment: Typos corrected. Published versio

THE PREVALENCE OF MALOCCLUSION AND ORTHODONTIC TREATMENT NEED IN A SAMPLE OF SYRIAN CHILDREN

Knowledge of a population’s epidemiological situation is vital in planning and provision of dental health services. The present study was undertaken to determine the prevalence of malocclusion and orthodontic treatment need in Syrian children. A randomly selected sample of 200 Syrian children aged between 8 and 13 years was collected from three different public schools in Damascus. For each participant, the records were a pair of dental study casts and a frontal intra-oral photograph. Firstly, Angle’s classification was used to classify malocclusion and the treatment need was assessed utilizing the Aesthetic Component (AC) and the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN). The treatment demand was also evaluated in association with gender and the connection between the two components of IOTN was statistically ascertained. The results of the study showed that more than one third of the subjects in the sample were in moderate to great need for orthodontic treatment. No significant difference in treatment need was found between genders and a statistically significant association was expressed between the two components of IOTN

Comparison between oxytocin, ergometrine and misoprostol in active management of the third stage of labour: a randomized controlled trial

Background: The aim of the present study was to compare the effectiveness of sublingual misoprostol, intravenous infusion of oxytocin, and intravenous infusion of Ergometrine in reducing blood loss during the third stage of labor.Methods: This is a no-random trial study conducted in in Ribat University Hospital, Khartoum among 150 laboring ladies with a healthy singleton pregnancy. After obtaining their written informed consent to participate in the study, they were randomly assigned to one of three possible treatment groups: 400 μg of sublingual misoprostol; 10 IU of intravenous infusion oxytocin; and 0.5 mg of intravenous infusion of Ergometrine. Blood loss was estimated by weighing the collected blood and converting the weight to milliliters.Results: The shortest mean duration of the third stage of labor was seen in patients who received misoprostol (3.89±0.37 min), followed by oxytocin (4.6±0.9 min), and Ergometrine (5.45±0.9 min). The lowest mean blood loss was seen in the patients who received 400 µg misoprostol (168.36±24.83 ml), followed by those who received 10 IU oxytocin (205.56±34.82 ml), and 0.5 mg Ergometrine (214.49±35.97 ml).Conclusions: Present study showed that 400 µg sublingual misoprostol was more effective than the conventional parenteral uterotonics in reducing the amount of the blood loss during the third stage of labor and has comparable effect to that of 10 IU intravenous oxytocin in shortening the duration of third stage of labor. It also showed that the use of misoprostol reduces the need for extra-uterotonics and blood transfusion

Practical dynamic de Bruijn graphs

International audienceAs datasets of DNA reads grow rapidly, it becomes more and more important to represent de Bruijn graphs compactly while still supporting fast assembly. Previous implementations have not supported edge deletion, however, which is important for pruning spurious edges from the graph. Belazzougui et al. Belazzougui et al. (2016b) recently proposed a compact and fully dynamic representation, which supports exact membership queries and insertions and deletions of both nodes and edges. In this paper we give a practical implementation of their data structure, supporting exact membership queries and insertions and deletions of edges only, and demonstrate experimentally that its performance is comparable to that of state-of-the-art implementations based on Bloom filters.
