Green synthesis of gold (CB-AuNps) and silver (CB-AgNps) nanoparticles using Cibotium barometz root extract was highlighted. CB-AuNps were synthesized almost instantly and CB-AgNps were formed after 25 min in a heated aqueous extract. The formation of CB-AuNps and CB-AgNps was detected at 548 and 412 nm; they were spherical with crystallite sizes of 6 nm and 23 nm, respectively. CB-AgNps were further investigated for their antimicrobial activity against Escherichia, Staphylococcus aureus, Salmonella enterica, and Pseudomonas aeruginosa...

This study is to screening the formulation and process variables that produce significant effect on the gedunin-loaded liposome formulations by using quality-by-design approach. Placket-Burman screening design was used to screen the most influencing formulation and process variables. Mean vesicle size, zeta potential, entrapment efficiency, and loading capacity were found in the range of 112-990 nm, -19.39 to -39.20 mV, 45.25-87.60%, and 3.54-10.47%, respectively. Differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD) result suggested that Gedunin encapsulated within liposome as amorphous state...

In recent decades, several scientists focused their process towards nanoparticles synthesis by using various sustainable approaches. Cocos nucifera (C. nucifera) was one of the versatile trees in tropical regions which also can act as a thrust quencher in all over the world. Cocos nucifera coir was one of the waste by-products in all coconut-refining industries and with the help C. nucifera coir, Palladium nanoparticles (Pd NPs) were synthesized. Green-synthesized spherical-shape Pd NPs were over layered by secondary metabolites from C...

Haemoglobin (Hb)-based oxygen carriers are under consideration as oxygen therapeutics. Their effect on apoptosis is critical, because the onset of pro-apoptotic pathways may lead to tissue damage. MP4OX, a polyethylene glycol-conjugated human Hb preserves the baseline level of neuron apoptosis with respect to sham. Here we develop a method for measuring Hb extravasation in brain. We exchange transfused rats by haemorrhaging 50% of their blood with simultaneous, isovolemic replacement with Hextend (negative control), MP4OX, or αα-cross-linked Hb...

Here a novel antibacterial nanocomposite was developed for combination cancer therapy. The synthesized nanocarrier was characterized by FTIR, (1)H NMR, thermogravimetric analysis (TGA), and FESEM-EDX. Its antibacterial activity was assessed by determining minimum inhibitory concentration (MIC) values. Doxorubicin (DOX) and methotrexate (MTX) conjugation with nanocarrier sustained the release of both drugs with apparent pH-triggered manner. Co-administration of DOX with MTX leads to an efficient anticancer performance to MCF7 cell lines verified by qRT-PCR and MTT assay tests...

Despite using lots of progression in hypersensitivity, it is not yet a cure. Current treatment for allergy focuses on two approaches, including treats only the symptoms of allergy by utilizing drugs and the other is desensitization therapy (immunotherapy), which involves administration of specific allergens. The main obstacle to hypersensitivity permanent treatment is the IgE producing subclass of B-lymphocytes which is the source of IgE- producing in hypersensitive patients. Removal of these lymphocytes causes noticeable reduction in the levels of IgE and allergic responses significantly...

Hemorrhage impairs myocardial contractile function and decreases oxygen delivery. This study investigates how polymerized bovine hemoglobin (PolyHb) solutions affect cardiac function after resuscitation from hemorrhagic shock (HS). Hamsters were hemorrhaged and resuscitated with PolyHb at 8.5 g/dL and 11.5 g/dL. Left ventricle (LV) function was assessed during shock and resuscitation using a miniaturize conductance catheter. PolyHb resuscitation had no beneficial effects in cardiac function; it increased cardiac afterload and systemic vascular resistance (SVR) of 46 and 116% for 8...

In several ocular diseases, the vascular endothelial growth factor (VEGF) level has been found to be upregulated. Bevacizumab, an anti-VEGF drug, is the most commonly used off level drug for these conditions. Delivery of drug to the posterior site is desired for the effective management of these diseases. The present study was to develop and optimize the chitosan (CS)-coated poly(lactide-co-glycolic acid) (PLGA) nanoparticles (NPs) of bevacizumab for sustained and effective delivery to posterior ocular tissues...

The present investigation deals with synthesis of graphene oxide (GO) and fabrication of GO-based hybrid nanocomposites (Ncs). Synthesized GO and Ncs were primarily confirmed by UV visible and Fourier transform infrared (FT-IR) spectroscopy. Fabricated Ncs showed potential antimicrobial activity against Gram-positive and Gram-negative bacterial strains. Surface morphology, Elemental analysis, and FTIR imaging analysis were carried out to confirm Ncs formation. The Ncs were impregnated into the pullulan polymeric layer-by-layer (LbL) ultrathin film by using novel spin-coating approach...
