COVID- 19, caused by the coronavirus SARS-CoV- 2, has arisen as a global health epidemic, claiming the lives of millions of people throughout the world. Combating the pandemic has involved developing and approving vaccines and antiviral products. Camostat Mesylate (Camo) is a TMPRSS2 inhibitor that inhibits virus-cell membrane fusion and, thereby,...

Zinc phosphate cement is used in dentistry to lute crowns and bridges. So far, its biocompatibility for other applications has not been studied. This paper reports the biocompatibility of zinc phosphate towards MG63 cells, testing both the material (discs; 3 mm diameter × 1 mm thick) and leachate from the cement. Cell viability was determined using...

Cancer is an unprecedented proliferation of cells leading to abnormalities in differentiation and maturation. Treatment of primary and metastatic cancer is challenging. In addition to surgery, chemotherapy and radiation therapies have been conventionally used; however, they suffer from severe toxicity and non‐specificity. Immunotherapy, the science...

Lung cancer is one of the grave diseases and accounts for 18% of cancer-related deaths. It has a high mortality rate due to early metastasis, rapid proliferation, low sensitivity, and poor specificity in early diagnosis. Nanotechnology can play a significant role in diagnosing lung cancer by employing nanomaterials as diagnostic reagents. Due to se...

The global menace of cancer has led to an increased death toll in recent years. The constant evolution of cancer therapeutics with novel delivery systems has paved the way for translation of innovative therapeutics from bench to bedside. This review explains the significance of mesoporous silica nanoparticles (MSNs) as delivery vehicles with partic...

RNA binding proteins (RBPs) enact a very crucial part in the RNA directive processes. Atypical expression of these RBPs affects many steps of RNA metabolism, majorly altering its expression. Altered expression and dysfunction of RNA binding proteins lead to cancer progression and other diseases. We enumerate various available interventions, and rec...

Purpose Intranasally administered unfractionated heparin (UFH) and other sulfated polysaccharides are potential prophylactics for COVID-19. The purpose of this research was to measure the safety and pharmacokinetics of clearance of intranasally administered UFH solution from the nasal cavity. Methods Double-blinded daily intranasal dosing in C57Bl...

Millions of people die each year from viral infections across the globe. There is an urgent need to overcome the existing gap and pitfalls of the current antiviral therapy which include increased dose and dosing frequency, bioavailability challenges, non-specificity, incidences of resistance and so on. These stumbling blocks could be effectively ma...

Most of the ayurvedic medicines are in the form of powder and they may have some kind of unacceptable or bitter taste and have problem of patient compliance. Medicines in powder form have problem of administration of accurate dose with ease. Furthermore it needs water or honey for administration and chances of spoilage and waste are more. Formulati...

Polymers are repeated structural units of one or more monomeric units. Several polymers have been investigated preclinically in vitro and in vivo in animals to evaluate their use in pulmonary drug delivery. The major concern associated with the use of polymeric systems for pulmonary drug delivery is their safety, biocompatibility, stability, and cl...

This study summarizes the synthesis, characterization, and evaluation of a library of biocompatible self-assembling Janus dendrimers (JDs) and their resulting nanostructures possessing either a cationic (NH3+), anionic (COO-), or neutral (OH) surface. Strategically designed for applications in therapeutic delivery, the dendrimers are comprised of a...

This study investigated the impact of different calcium reagents on the morphology, composition, bioactivity and biocompatibility of two-component (CaO-SiO2) glasses produced by the Stöber process with respect to their potential application in guided tissue regeneration (GTR) membranes for periodontal repair. The properties of the binary glasses we...

The barriers in the delivery of the therapeutic agent to brain diseases are blood–brain barrier (BBB), blood-cerebrospinal fluid barrier, and cellular barriers. The above mentioned barriers limit the distribution of the therapeutic agent or drug delivery system, thereby affects the therapeutic efficacy. The route of administration is also an import...

Most of the ayurvedic medicines are in the form of powder. Being in powder form the administration of accurate dose with ease is a problem. They may have some kind of unacceptable bitter taste. Furthermore it needs water or honey for administration and chances of spoilage and waste are more. Oro-dispersible tablet which rapidly disintegrating in mo...

The catechin, epigallocatechin gallate (eGCG), found in green tea, has inhibitory activity against a number of protein toxins and was investigated in relation to its impact upon ricin toxin (RT) in vitro. The IC50 for RT was 0.08±0.004ng/mL where as the IC50 for RT + 100μM eGCG was 3.02±0.572ng/mL, indicating that eGCG mediated a significant (p<0.0...

A composite membrane of the polymer, chitosan, and the silver-exchanged mineral phase, tobermorite, was prepared by solvent casting and characterised by scanning electron microscopy and Fourier transform infrared spectroscopy. The in vitro bioactivity, cytocompatibility and antimicrobial activity of the composite were evaluated with respect to its...

The microscopic imaging of specific organelles has become a staple of the single-cell assay and has helped define the molecular regulation of many physiological processes. This definition has been made possible by utilizing different criteria to identify specific subpopulations of organelles. These criteria can be biochemical, immunological, or phy...

The reaction of the five-membered C,N-palladacycle [(L)PdCl](2), where LH = 1-methyl-5-phenyl-1H-1,4-benzodiazepin-2(3H)-one, with 1,2-ethanebis(diphenylphosphine), dppe, leads to the formation of the bridged palladacycle. [Pd(2)L(2)(mu-dppe)Cl(2)] 3, which was characterised in solution by (1)H and (31)P NMR spectroscopy and in the solid state by X...

The Knoevenagel condensation of 1,3-dihydro-2H-indol-2-one with ferrocene carboxaldehyde afforded an approximate 2:1 mixture of the geometrical isomers (E)- and (Z)-3-ferrocenylmethylidene-1,3-dihydro-2H-indol-2-one respectively in an overall 67% yield; the air and solution-stable isomers were readily separated by preparative thin layer chromatogra...

The reaction between alpha,beta-poly(aspartylhydrazide) (PAHy), a water soluble synthetic polymer and 3-(carboxypropyl)trimethyl-ammonium chloride (CPTACl) produced copolymers bearing permanent positive charges (PAHy-CPTA) with molecular weight of 10 kDa and PAHy-CPTA copolymers differing in positive charge amount (18-58%) were chosen for biologica...
