Hydrogels are three-dimensional, hydrophilic networks of polymers with a high water absorption capacity. We investigated the removal of monovalent cationic dye, methylene blue, from aqueous solutions by a polyvinyl alcohol/Sodium alginate/Starch mix hydrogel to discover a solution to the environmental waste-water problem. By applying a gamma radiation dose from a Co-60 source without adding a hazardous cross-linker, a novel PVA/SA/Starch mix hydrogel was synthesized. The effects of factors like irradiation dose and [...]

Background: Cardiac allograft vasculopathy (CAV) remains a major obstacle to long-term heart allograft survival. A number of studies show that immune mechanisms are involved in CAV. Using non-invasive cellular MRI (CMRI) to explore indicators of CAV lesions and characterize its development could provide new insights into the target immune cells that are responsible for the progression of CAV and reveal early markers of the disease before irreversible changes occur. Methods and Results: Rat heart transplant allograf [...]

Sasthamkotta Lake eco-region is a freshwater Ramsar site in Kerala, India. Eco-regions are ecologically and geographically defined larger land or water mass areas with a characteristic assemblage of the ecosystem and significant biodiversity. A decentralized and locally self-sustaining mechanism has been achieved in managing this eco-region by a participatory model through a joint Biodiversity Management Committee (jBMC) constitution. BMCs are custodians of the environment, and biodiversity, confined to a village/P [...]

Lifestyle and dietary interventions can have a significant impact on patients with dyslipidemia and should be encouraged with the use of dietary supplements. With new research, there is evidence that using dietary supplements, specifically nutraceuticals can be helpful for cholesterol management. Four commonly used supplements are: Red Yeast Rice, Omega 3 Fatty Acids, Niacin and Berberine.

Recently the GexOy nanomaterials have been studying intensively due to their interesting electronic materials, which have many particular properties and applications in nanotechnology and nano-devices fabrication. Much work has been done on many different synthesis methods and their properties of Ge and GexOy nanomaterials. However, the effects of the different Ge substrate surface states and Au catalyst layer thicknesses on the formation of different forms/morphologies of nanomaterials (nanowires, nanorods, nanopa [...]

Rural and remote communities are more vulnerable to damage caused by extreme events as compared to urban areas. Natural disasters can disrupt basic supplies such as domestic water supply and cooking needs in addition to electricity outages. The recognition of the interlinked nature of food, water and energy has gained momentum over the past few years. Smart Integrated Renewable Energy System (SIRES) has been proposed to handle basic needs such as cooking, domestic and irrigation water supply, and electricity to rem [...]

(1) Background: Within this study, we assessed the effects of acupuncture on heart rate variability (HRV) in Chinese post-stroke patients. (2) Methods: In 30 Chinese post-stroke patients (14 f, 16 m; mean age ± SD 64.3 ± 3.8 years; range 40 - 80 years) electrocardiographic signals before, during and after acupuncture at the left Weizhong acupoint (BL40) were recorded in Harbin and analyzed in Graz using teleacupuncture via internet. HRV data were analyzed in the time and frequency domain and a protoco [...]

This review summarizes the latest results from the interventional clinical trials for inducing clinical tolerance in the recipients of human leukocyte antigen (HLA)-matched or mismatched living donor kidney transplants via allogeneic hematopoietic stem cell (HSC)-based therapies. The protocols utilized by the three medical centers in the United States differ in degree of HLA-matching, relatedness or unrelatedness, donor cell composition of the hematopoietic stem cells transplant (HSCT), timing for infusion and cond [...]

Introduction of biocompatible ingredients into nano-material formulations has been studied as a strategy for the enhancement of the pharmacokinetics as well as pharmacodynamics of the final product. With the aim of enhancing drug loading and the ultimate efficacy, incorporation of Bovine Serum Albumin (BSA) into carbonate apatite (CA) nanoparticles structure was employed in the present study. As a result of BSA embedding in the CA formulation, approximately three-times higher loading efficiency was achieved for pac [...]

Background: To estimate the survival of patients in the heart transplantation waiting list (HTx WL) at Almazov National Medical Research Centre (V.A. Almazov NMRC), Saint-Petersburg, Russia, from 2010 to 2017 and to define risk factors for death among these patients. Methods: It was a single-center retrospective study involving 151 patients with advanced chronic heart failure (CHF) in the HTx WL. Results: Mortality in the HTx WL for the period 2010-2017 was found to decrease. Based on the results of constructing th [...]
