In this work, dynamically tunable, superlyophobic surfaces capable of undergoing a transition from profound superlyophobic behavior to almost complete wetting have been demonstrated for the first time. In the initial state, with no voltage applied, these surfaces exhibit contact angles as high as 150°for a wide variety of liquids with surface tensions ranging from 21.8 mN/m (ethanol) to 72.0 mN/m (water). Upon application of an electrical voltage, a transition from the superlyophobic state to wetting is observed. We have examined experimentally and theoretically the nature of these transitions. The reported results provide novel methods of manipulating liquids on the microscale.
The floating and sinking of objects on fluid-fluid interfaces occurs in nature, and has many important implications in technology. Here, we study the stability of floating self-assembled spheres on an oil-water interface, and how the sphere deposition geometry affects the size limits of the assemblies before they collapse and sink through the interface. Specifically, we compare the critical size of particle rafts to particle stacks. We show that, on liquid-liquid interfaces, monolayer rafts and stacked spheres exhibit different scaling of the critical number of spheres to the Bond number-the dimensionless ratio of buoyancy to interfacial tension effects. Our results indicate that particle stacks will sink with a lower threshold number of particles than particle rafts. This finding may have important implications to engineering applications where interfacial assemblies are not monolayers.
Anaemia (particularly iron deficiency) is of important concern in patients with chronic kidney disease (CKD) as it reflects the outcome of the disease. Current recommendations for the use of intravenous iron (IV) therapy in the management of anaemia in such patients are limited. This study highlights the comparison of oral to intravenous iron in patients with chronic kidney disease. Materials and methodsThis is a prospective case-control study comparing intravenous iron to oral iron in chronic kidney disease patients admitted to the Medicine Department of Acharya Vinoba Bhave Rural Hospital, in central India from October 2018 to October 2020. A total of 150 patients were divided into two groups of 75 each, one receiving oral iron (ferrous sulfate 325 mg tablets) and the other intravenous iron (IV iron sucrose). ResultsSerum iron, serum ferritin, and transferrin saturation (TS) showed increased levels in the IV iron group than in the oral iron group. In the IV group, a statistically significant increase was found in haemoglobin levels after therapy among all stages of kidney disease (p<0.05) while the same was not reported in the oral iron group. ConclusionIV iron sucrose therapy had been found to be effective, well-tolerated, and more successful than oral iron treatment in chronic kidney disease patients as far as the parameter of iron deficiency anaemia is concerned.
Diffuse alveolar hemorrhage (DAH) is bleeding into the alveolar spaces of the lung. DAH is often associated with systemic autoimmune diseases, coagulation disorders, drugs, inhaled toxins, or transplantation. This study describes a rare case of acenocoumarol-induced DAH, a pulmonary disorder, which has not been reported before. A 48-year-old male presented with a history of rheumatic heart disease with mitral stenosis with moderate mitral regurgitation status post mitral valve replacement. He was taking acenocoumarol but did not keep his prothrombin time-international normalized ratio (PT-INR) monitoring and came to the hospital with complaints of cough, hemoptysis, and breathlessness. Chest x-ray and high-resolution computed tomography (HRCT) thorax were done which revealed diffuse patchy opacities and pulmonary hemorrhage, respectively. After nine days of hospital stay with appropriate management with corticosteroids, antibiotics, and intravenous fluids, the patient was doing well.
Introduction: Breastfeeding is a natural source of enormous value and is necessary for the life of babies. The influence of infants' eating patterns, on subsequent cholesterol levels is of interest. Breastfeeding has been found to be protective against atherosclerotic cardiac diseases and better lipid profile later in life compared to bovine milk. Hence, the study was carried out with aim to compare the lipid profiles of exclusively breastfed infants and cow milk fed babies. Material and Methods: It was a Prospective Observational Study conducted among fifty exclusively breastfed babies and fifty exclusively cow milk fed babies. Lipid profile were compared at three and six month of life over a span of one year in Rohilkhand Medical College and Hospital, Bareilly who fulfilled inclusion criteria of study. Results: In the present study, the exclusive breastfed babies showed lower levels of cholesterol and low density lipoprotein, rising levels of HDL/LDL ratio, high density lipoprotein in exclusive breastfed babies as compared to cow milk fed babies which showed declining concentrations of high density lipoprotein, HDL/LDL ratio, rising levels of low density lipoprotein. Conclusion: The study was conclusive of the fact that exclusive breastfeeding for initial six month of life shows an edge to the positive lipid profile (decreasing cholesterol, low density lipoprotein, triglycerides, and increasing high density lipoprotein and HDL/ LDL ratio) over six month as compared to exclusively cow milk fed babies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
