Abstract

This study intends to fabricate new biodegradable and antimicrobial membranes based on crosslinked gelatin/chitosan biopolymers. Cinnamaldehyde was incorporated into membranes for boosting their antimicrobial activities. FTIR spectroscopy and electronic spectrum analysis were used to prove their chemical structures, while SEM and TGA analysis were applied to investigate the morphological changes and the thermal properties of the crosslinked membranes. Moreover, ion exchange capacity, wettability and mechanical analysis were also conducted to get more information about the physicochemical properties for the developed membranes. Four different types of bacteria have been used for studying the antibacterial activities of the crosslinked membranes (one gram-positive and three gram-negative bacteria). The results showed a significant augmentation in the inhibition percent with increasing cinnamaldehyde content in the membrane matrix. Besides, hemocompatibility, biodegradability, and cytotoxicity studies were performed and the findings emphasized that the as-fabricated biodegradable gelatin/chitosan/cinnamaldehyde membranes could be efficiently used as antibacterial dressers for ameliorating the wound healing.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
