Uncontrolled haemorrhage is one of the leading causes of death. This issue is present in controlled environments, such as hospitals, as well as pre-hospital and remote locations. Treatment is more challenging in remote locations where there is a lack of effective products to deliver oxygen and control coagulation. Poorly treated haemorrhage can lead to rapidly deteriorating bodily conditions that can result in organ failure and tissue death. Thus, the availability of products to support oxygen delivery to tissues and coagulation processes within the body is essential for the effective treatment of severe haemorrhage, particularly in out-of-the-hospital settings...

Targeted drug delivery has received considerable attention due to its key role in improving therapeutic efficacy and reducing the side effects of anticancer drugs. Bleomycin (BLM) is an anticancer antibiotic with short half-life, low therapeutic and high side effects that limit its clinical applications. This study aims to evaluate the anticancer potential of folate-targeted liposomal bleomycin (FL-BLM) and its free-folate form (L-BLM) on two different cancer cell lines including human cervix carcinoma HeLa, and human breast carcinoma MCF-7 cells...

With increasing gap in the demand and supply of vital organs for transplantation there is a pressing need to bridge the gap with substitutes. One way to make substitutes is by tissue engineering which involves combining several types of synthetic or biomaterials, cells and growth factors cross-linked together to synthesize a functional scaffold for repair or replacement of non-functional organs. Nanoparticle based composites are gaining importance in tissue engineering due to their ability to enhance cell attachment and proliferation...

Curcumin, a natural polyphenol, exhibits anti-oxidant, anti-inflammatory, anti-neoplastic and chemopreventive properties. In fact, targeting of this natural anticancer agent has received a great deal of attention during the recent years. In this study, we proposed that curcumin conjugation with lactoferrin molecules may lead to a potential drug delivery system targeted toward cancerous cells through both active and passive targeting. In this regard, curcumin conjugated lactoferrin was developed via a carbodiimide-based coupling reaction and the resulting conjugates were appraised for their molecular properties as a potential targeted drug delivery system...

Herein, ZnO nanoparticles were synthesized using microwave-assisted method in the presence of Vaccinium arctostaphylos L, fruits extract. The structure, size, morphology and optical properties of the samples were characterized by XRD, SEM, TEM, EDX, FT-IR, UV-vis DRS and TGA analysis. A decrease in crystallite size was observed for the biologically synthesized ZnO compared to the chemically synthesized sample. Furthermore, the existence of organic moieties over the biologically synthesized ZnO NPs was approved using characterizing methods...

The stability of mulberry-extracted anthocyanin is a main concern in food supplement application. In this article, the alginate/chitosan beads were fabricated by spray drying and external gelation techniques using different processes: (1) dropping a sodium alginate solution into a CaCl2 solution containing chitosan and (2) incubating calcium alginate beads in a solution of chitosan. These beads were introduced as microcarrier to enhance the stability and bioavailability of anthocyanin. We showed that the beads fabricated by different processes could encapsulate the anthocyanin at different amounts...

The healthcare area is often reluctant to execute new technology unless they are proven to be safe, constructive and secure. Eventually, an aspiration stands for providing point-of-care testing service to allow a better estimation of the biochemical levels of a patient that entails an insistent remedial action. With increasing mortality rate due to cardiovascular diseases (CVDs) in present scenario, it has become the need of hour to develop more advance methods for their diagnosis, so that it can be determined at sensitive levels and can be prevented from being fatal...

Chrysin (Chr) is a naturally occurring flavone with a wide spectrum of biological functions including anti-cancer, anti-inflammatory and anti-oxidant properties. Due to the low bioavailability and in vivo stability of Chr at therapeutic levels for wound-healing applications, Chr-loaded PCL/PEG nanofibrous mats were successfully fabricated by optimizing the electrospinning parameters and characterized using FE-SEM and FTIR. Results of MTT showed that Human foreskin fibroblast cells (HFF-1) have more than 80% viability on Chr-loaded nanofibers...

HCl) (as a water-soluble drug):Eudragit(®) RS100 (Eud) nanobeads and nanofibres applying the electrospraying method as an economical and one-step technique. Different ratios of Prop. HCl:Eud (i.e. 1:5 and 1:10) at total solution concentrations of 10-20% W/V were investigated. The FE-SEM studies revealed that morphology and size of the samples were highly affected by the solution concentration; so that, the nanobeads (a mean diameter of 82...

The design of mild and non-toxic synthesis of metallic nanoparticles is a topical subject in the nanotechnology field. The objective of this present study is to screen the bioactivity of biosynthesized nanoparticles by aqueous fruit extract of Chaenomeles sinensis. The reducing and stabilizing ability of C. sinensis to fabricate gold (Cs-AuNps) and silver (Cs-AgNps) nanoparticles was confirmed by UV-visible (UV-Vis) spectroscopy at 562 nm and 477 nm, respectively. The field-emission transmission electron microscopy (FE-TEM) and X-ray diffraction analysis (XRD) verify the nano-scale morphology and crystallinity of Cs-AuNps (20-40 nm) and Cs-AgNps (5-20 nm)...

Stem cells of dental origin emerged as a new source for the regeneration of tissues with advantages mainly including non-invasive collection procedures and lack of ethical contraversies with their harvest or use. In this study, porcine TGSCs (pTGSCs) were isolated from mandibular third molar tooth germs of 6-month-old domestic pigs. This is the first study that reports the isolation and characterization of TGSCs from porcine third molars and their differentiation depending on STRO-1 expression. PTGSCs were sorted according to their STRO-1 expression as STRO-1(+) and STRO-1(-)...

In the present study, a sustainable green chemistry approach was established to fabricate magnetic Fe3O4 nanoparticles (Fe3O4NPs) using the aqueous fruit extract of edible C. guianensis (CGFE). Synthesized NPs were further confirmed with different high-throughput characterization techniques such as UV-visible spectroscopy, FT-IR, XPS, DLS and zeta potential analysis. Additionally, XRD, AFM, HRTEM and SQUID VSM demonstrate the generation of crystalline CGFe3O4NPs with mean diameter of 17 ± 10 nm. Interestingly, CGFe3O4NPs exhibit a stupendous bactericidal action against different human pathogens which depicts its antimicrobial value...

Green synthesis of AgNPs has gained many research interests as a low cost and eco-friendly approach. This work reported on the use of bacterial genomic DNA as the alternative biopolymer for a green production of AgNPs under a neutral pH. Although both ssDNA and dsDNA could function as stabilizing agents during the synthesis process, the ssDNA, generated by pre-heating the dsDNA at 100 °C, was more efficient to produce AgNPs with higher yield as determined by the intensity of the surface plasmon resonance (SPR) peak of silver at 475 nm...

Candida species are pleomorphic, commensal fungi associated with candidiasis. The extracellular hydrolytic-secreted aspartyl proteinases are recognized as chief agents for pathogenesis of Candida species, involved in the degradation of proteins and adhesion during biofilm formation. This study aimed at exploring inhibitory effect of mycogenic silver nanoparticles (Ag NPs) against C. albicans and non-albicans' biofilm growth and aspartyl proteinase enzyme activity in-vitro. Biofilm forming, drug-resistant clinical isolates of C...

In the present work, we studied the reduction of gold ions into gold nanoparticles using Nigella arvensis leaf extract in the one-step green synthesis method. The formation of N. arvensis gold nanoparticles (NA-GNPs) was confirmed by UV-Vis spectroscopy, XRD, FT-IR and TEM analyses. The XRD pattern confirmed the crystal structure of NA-GNPs, and TEM image showed the small size (3-37 nm) and almost spherical shape of NA-GNPs. NA-GNPs have not shown enhanced antioxidant properties compared to the plant extract while they were active against the clinical isolated bacterial strains...
