Potential of Tribological Properties of Metal Nanomaterials in Biomedical Applications.

Potential of Tribological Properties of Metal Nanomaterials in Biomedical Applications. Adv Exp Med Biol. 2019 Dec 05;: Authors: Shende P, Patel D Abstract Metallic nanomaterials show tremendous applications in biomedical devices due to compatible integration into the most of the biological systems as they are nano- structured. Metallic nanomaterials are capable of mimicking all the three major antioxidant enzymes such as catalase (CAT), peroxidase and oxidase, to control the level of reactive oxygen species (ROS) inside the cell as an alternative strategy over conventional one which has biological toxicity and have several adverse effects, if accumulation takes places during the treatment. This anti-oxidant property of metallic nanomaterials demonstrates as a promising candidate for its biomedical application in disease conditions where the excessive level of ROS causes damage to DNA, lipids and protein in several conditions such as diabetes, cancer and neurodegenerative diseases. Tribology is the study of interacting surfaces in motion and the measurement of properties such as friction, wear-tear and abrasion. While designing nano-scale biomedical devices, the consideration of tribology is particularly important because the high surface area ratio enhances problems with friction and wear-tear which can further affects its function as well as longevity.

Authors: Okan Cakir M, Kirca O, Gunduz S, Ozdogan M Abstract Infections in immunocompromised-neoplastic patients represent a severe complication. Among bacteria, Enterococcus species constitute a common causative pathogen of urinary tract infections (UTIs), especially among hospitalized patients with or without urinary tract carcinoma, related commonly to urinary tract abnormalities, urinary catheters or prolonged antibiotic treatment. Although enterococci have been considered more commonly as colonization bacteria in the intestine than virulent agents, they are frequently implicated in UTIs. The high incidence of ...

Immune checkpoint inhibitors (ICIs) have been widely used in the treatment of various types of cancers worldwide. Although ICI-related autoimmune diabetes is a rare complication, it can be associated with a life-threatening condition, diabetic ketoacidosis (DKA). Here, we report the cases of four patients who presented with ICI-induced DKA in a tertiary center in Korea. Three patients were newly diagnosed with type 1 diabetes, and one patient was known to have a history of type 2 diabetes. All DKA cases were due to programmed cell death protein-1 (PD-1) or its ligand inhibitors (PD-L1). The mean age of the patients was 71....

Undergoing earlier menopause is a sign of a greater burden of age-related damage and dysfunction, so it should not be surprising to see that this correlates with a greater incidence of chronic disease in the years thereafter. People with a greater burden of cell and tissue damage tend to exhibit all of the manifestations of aging earlier than their less damaged peers. These variations in damage burden and consequences from individual to individual are near all the results of lifestyle choices, particularly smoking, weight, and exercise, and environmental factors such as exposure to chronic viral infection. Genetics plays o...

Molecules, Vol. 25, Pages 549: Adropin as A Fat-Burning Hormone with Multiple Functions—Review of a Decade of Research Molecules doi: 10.3390/molecules25030549 Authors: Jasaszwili Billert Strowski Nowak Skrzypski Adropin is a unique hormone encoded by the energy homeostasis-associated (Enho) gene. Adropin is produced in the liver and brain, and also in peripheral tissues such as in the heart and gastrointestinal tract. Furthermore, adropin is present in the circulatory system. A decade after its discovery, there is evidence that adropin may contribute to body weight regulation, glucose and lipid ...

by Roc ío Vega, Manuel Carretero, Rui D. M. Travasso, Luis L. Bonilla During angiogenesis, new blood vessels sprout and grow from existing ones. This process plays a crucial role in organ development and repair, in wound healing and in numerous pathological processes such as cancer progression or diabetes. Here, we present a mathematical model of early stage angioge nesis that permits exploration of the relative importance of mechanical, chemical and cellular cues. Endothelial cells proliferate and move over an extracellular matrix by following external gradients of Vessel Endothelial Growth Factor, adhesion and st...

AbstractKinase inhibitor selectivity is a major concern for the design of small-molecule compounds. As a member of serine/threonine protein kinase family, glycogen synthase kinase 3 β (GSK3β) is involved in diverse biological processes and abnormal dysregulation of its activity has been associated with several pathologies, including type II diabetes, Alzheimer’s disease, bipolar disorders, and cancers. A small-molecule PF-367 significantly inhibited the GSK3 enzymatic activ ity over its closest cyclin-dependent kinase 2 (CDK2) with>1000-fold selectivity. However, the PF-367 selectively binding to GSK3 &b...

ConclusionP. karwinskii leaf extract inhibited reactive oxygen species and exerted an anti-inflammatory effect. Moreover, this extract did not induce gastric damage in the animals. The bioactivity of the species was found to support its traditional use in traditional medicine. This orchid could be used to treat inflammatory diseases without causing the side effects associated with Nonsteroidal anti-inflammatory drugs. It can also be employed to treat other pathological conditions associated with oxidative stress. The findings herein form the basis for the future discovery of natural products that may serve as safe alternat...
