One of the ways to improve the fusion of an implant with bone tissue is through the use of biocompatible coatings, in particular, hydroxyapatite (HAp). It is important to assess the strength of the HAp adhesion to the implant. The measure of the strength of the bond of the coating with the substrate is the energy of this bond. Using density functional theory and molecular dynamics, the reaction path, reaction products, oscillation frequency, activation energy and bond energy between different combinations of compon [...]

This paper reviews the relationship between RBD and PD and the pathophysiology. Most RBD patients develop PD within 14 years. PD pathophysiology is α-synucleinopathy with dopamine degeneration in nigrostriatal pathways. RBD pathology is poorly understood. Anomalies suggest RBD and PD are different, evidenced by smoking. RBD and PD are associated with glucocerebrosidase gene mutations (GBA gene), suggesting RDB with GBA gene mutation predicts PD. PET imaging, assessing vesicular monoamine transporter 2 (VMAT2), inde [...]

Increased body fat mass can lead to lifestyle diseases such as hypertension, diabetes, and hyperlipidemia. Metabolic syndrome is a cluster of conditions that increases the onset of multiple diseases, such as cardiovascular diseases, stroke, and type 2 diabetes, which are closely related to lipid metabolism; therefore, new prevention approaches and treatments are needed. Our study investigated the effects and mechanism of YNCRG on anti-obesity in metabolic syndrome model SHR.Cg-Leprcp/NDmcr (SHRCP) rats. Eight-week- [...]

The present study deals with the development of scaffolds based on gelatin (G) and/or chitosan (CH) through modifications in the central processing method. This process consists of the fabrication of a hydrogel which is, then submitted to a freeze-drying stage. To compare the effects of the different modifications, the mechanical properties of the various systems were characterized, employing both dynamic compressive strain and frequency sweep tests. In addition, their porosity as well as the structure and fiber di [...]

This article explores difficulties encountered by those with no personal experience of a chronic disease or disability in accurately evaluating the quality of life with a condition present from birth. In most countries, cost-effectiveness analysis relies on ratings of health states by members of the general population, who must try to imagine what life for those affected is like based on (usually brief) descriptions of the conditions. That task is challenging for reasons that have been well-discussed in the literat [...]

The high prevalence of obesity is a global concern. However, obesity and inflammatory bowel disease have similarities in epidemiology, diet, and gut microbial dysbiosis. An omnivorous (westernized) diet replacement with a plant-based diet in inflammatory bowel disease achieved better outcomes in both the induction and quiescent phases. Educational hospitalization providing a plant-based diet was found effective in suppressing flare-up in ulcerative colitis. This case report was designed to assess whether a plant-ba [...]

Lung transplantation (LTx) is the gold standard for the surgical treatment of end-stage lung disease. Ongoing discussions persist whether single lung transplantation (SLT) or bilateral lung transplantation (BLT) lead to better patient outcomes and quality of life. This study analyzed 58 peer-reviewed articles from 1990 to 2024, comparing SLT and BLT across several parameters, including indications for transplantation, overall survival, pulmonary hypertension, complications, chronic rejection, functional status, and [...]

Flows in multi-branch piping systems are modeled for linear Newtonian and nonlinear Power Law, Bingham Plastic and Herschel-Bulkley fluids. The nonlinear models are often used to describe multiphase fluids consisting of liquid and solid phases, including cement slurries and drilling muds in petroleum engineering. Rheological and heterogeneous multiphase effects are important to blood flows in single and bifurcated arteries, capillaries and veins – biological applications are also emphasized to highlight their incre [...]

After the completion of the human genome project, there have been many advances in the field of genetics. With next generation sequencing, patients can undergo genomic analysis through whole exome or whole genome testing. These comprehensive tests can shorten the diagnostic odyssey and guide medical management and thereby potentially reduce mortality and morbidity. To date, parents and physicians have reported positive perceptions of using these genomic testing even when a diagnosis is not made. Remaining challenge [...]
