Deformation of Nanoglass under High-pressure Torsion
Metallic glasses are amorphous solids with metallic atomic bonds. Different from traditional crystalline metals, they have no long-range atomic order. Only short-range order on the scale of 0.5–1 nm can be detected. Because of the lack of a lattice dislocation slip system, as in crystalline alloys, metallic glasses exhibit some outstanding properties,

Around the world, viral infections have impacted civilizations’ circumstances since the earliest times, including the current panorama of the SARS-CoV-2 pandemic known as coronavirus disease in 2019 (COVID-19). In this sense, in the last century,
In silico Analysis for the Repurposing of Broad-spectrum Antiviral Drugs against Multiple Targets from SARS-CoV-2: A Molecular Docking and ADMET Approach
SARS-CoV-2 belongs to the genus Beta of the Coronaviridae family of enveloped single-stranded, positive-sense ribonucleic acid (RNA) with a genome length of 30,000bp. The virion is composed of various non-structural (RNA dependent RNA polymerase also known as RdRp) and structural proteins such as Spike (S), Nucleocapsid (N), Matrix (M), and Envelope (E) proteins.
Multidirectional Benefits of Nanotechnology in the Diagnosis, Treatment and Prevention of Tuberculosis
Despite the curious advancement in medical science and therapeutics, tuberculosis (TB) persist the primary factor of mortality than any other infectious disease and socioeconomic disaster for millions of people around the world. According to the World Health Organization (WHO), World’s One-third of the population is infected with this disease and of these, 8 to 10 million people develop active disease and 2 million people die each year and the rest of the infected people remain asymptomatic.
Green Nanotechnology: The Influence of Intermolecular and Supramolecular Interactions
In the last decade, the study of nanometer-scale particles has grown exponentially worldwide. This growth is due to the broad field of nanostructures applications, which, due to their dimensions in nanometric sizes, have new properties not found in micro and macro scale. These properties result from the increase in the ratio between the surface area and volume, and the nanostructures’ size directly influences these. Tolerance to temperature, variety of colors, changes in chemical reactivity,
The Possible Role of Molecular Vibration in Intracellular Signalling
The exchange of information within the cell is extremely complex. Besides the well-studied chemical signalling, physical signalling is required to fulfil spatial and temporal aspects. The Golgi apparatus and the microtubule skeleton system are the decisive structures for numerous intracellular transport tasks.
Nanotechnology in Water Treatment: An Optimistic Perspective for the Near Future
Unequal access to drinking water and basic sanitation are old issues in Brazil and worldwide. Besides, this situation foments the proliferation of infectious parasitic diseases. Moreover, mainly in underdeveloped countries, it victimizes socioeconomically vulnerable people. The degree of water contamination analysis, usually by fecal matter, is made by the number of microorganisms present in the sample, including Escherichia coli or thermotolerant coliforms. In addition, several
Folic acid-chitosan Nanomaterials for delivery of dietary polyphenols
Despite the health benefits associated with polyphenols, the bioavailability of many polyphenols limits their effects. Problems with poor solubility fast-metabolism and food preparation techniques limit the bioavailability and bioactivity of these dietary micronutrients. Encapsulation of polyphenols has shown to protect and increase bioavailability of these dietary compounds and to enhance their anticancer activity.
Altered Peak C-peptide and Fasting Blood Glucose in Children with Autism Spectrum Disorder
ASD refers to a group of complex neurodevelopmental disorders, characterized by deficits in social communication, interaction and demonstrating restricted, repetitive, and stereotyped patterns of behavior. Centers for Disease Control and Prevention forecasted that the prevalence of ASD would be 1 in 45 in USA.

Nanoscale Chitosan-Based Hemostasis Membrane
Excessive bleeding or hemorrhage in traumatic injuries is the leading preventable cause of death in the combat and civilian trauma centers. Nearly 50% of military deaths, 90% of military battlefield casualties, and 33-56% mortalities in civilian’s surgical bleeding are associated with severe bleeding and can be prevented. Hence, significant and rapid hemostasis or bleeding control require innovative strategies with easy to use, stable, and inexpensive processing. Furthermore, the developed hemostatic material should ensure biocompatibility and biodegradability with non-immunogenic properties. To date, a wide variety of hemostatic powders, dressings, and bandages have been investigated as useful materials in reducing hemorrhage.
Aberrant Signaling Pathways in Cancer Cells: Application of Nanomaterials
Cell signaling pathways involve several proteins, called kinases, to pass on vital messages from the transmembrane-proteins, e.g., receptor tyrosine kinases (RTKs) to the nucleus of a cell through a cascade of processes for various activities such as controlled cell division, proliferation, apoptosis, metabolism, DNA replication and repair. Alterations in these signaling proteins combined with genetic and/or epigenetic mutations spawn various types of cancer that empowers the cells to ignore or maneuver the immune signals and carry on felonious activities such as uncontrolled cell division and growth, genetic instability, angiogenesis around the tumor in hypoxia, eluding the body’s immune system, cell migration, and invasion of surrounding healthy cells.

Comparison of Horizontal blaCTX-M Gene Transfer via Conjugation among Extended Spectrum β-Lactamases Producing Escherichia coli Isolates from Patients with Urinary Tract Infection, Their Animals and Environment
The dissemination of the extended spectrum β-lactamases (ESBL) producing E. coli poses a significant public health problem. Understanding the efficiency and frequency of horizontal gene transfer via conjugation of ESBL producing E. coli is imperative towards devising prevention and control measures. This study compared the frequencies and efficiencies of horizontal blaCTX-M gene transfer via conjugation among Escherichia coli isolates from urine and gastrointestinal tract (GIT) of patients with urinary tract infection (UTI), their animals and environment.
