ABSTRACT The present article deals with the preparation and characterization of pure lead oxide (PbO) nanoparticles embedded polyvinyl alcohol (PVA) films by using a colloidal processing technique. PbO were successfully synthesized simple precipitation method. Polymer/ceramic‐based flexible self‐standing obtained further characterized various analytical techniques. mechanical dielectric properties also investigated. Fourier Transform Infrared Spectroscopy (FTIR) results indicate that...

An intensive idea of bone tissue engineering is to design regenerative nanofibrous scaffolds that could afford a natural extracellular matrix (ECM) microenvironment with the ability induce cell proliferation, biodegradation, sustained drug release, and bioactivity. Even mechanical properties orientation nanofibers may enhance performance scaffolds. To address this issue, we designed novel sandwich-like hybrid silk fibroin (SF)/silica/poly(vinyl alcohol) (PVA) The developed scaffold was...

Novel tertiary nanocomposite films comprising of poly (vinyl alcohol) (PVA), (4-styrenesulfonic acid) (PSSA) and titanium dioxide (TiO2) nanoparticles (NPS) were prepared using simple solvent casting method. The structural, thermal, morphological, thermo-mechanical electromagnetic interference (EMI) shielding properties PVA/PSSA/TiO2 investigated. EMI effectiveness (SE) in the X Ku band was found to be 12 dB 13 respectively at 25 wt% TiO2 NPs loading. These results demonstrate possible...

Hypericin, also known as naphthodianthrone, is a naturally occurring photosensitiser derived from anthraquinone. It has gained attention owing to its prospective use in photodynamic therapy (PDT) for cancer treatment. PDT minimally invasive treatment that utilises light, photosensitiser, and oxygen kill the target cells. However, conventional synthesis methods of hypericin harm environment human health. Therefore, researchers focused on developing green extraction overcome these limitations....

The aim of this study is to investigate the dosimetric effects rotational uncertainties in patient positioning on target coverage stereotactic radiosurgery (SRS) multiple brain metastases using single isocenter volumetric modulated arc therapy (VMAT).Ten SRS cases with (2-8) planned non-coplanar VMAT technique were investigated study. Pitch, yaw and roll displacements 1, 3 5° simulated about along each axes nine plans obtained for case. Gross tumor volume (GTV) compared original plan four...

Magnetic nanoparticles have attracted increasing attention due to their potential applications in many industrial fields, even extending use biomedical like drug delivery system, Implants, biosensors, lab on a chip, image enhancement, hyperthermia therapy and so on.For better experimental magnetic are encapsulated. The coating material used this study is pullulan. Pullulan non toxic, immunogenic, plasma expanders which coated with the nanoparticles. Acetylation of pullulan carried out using...

Hydroxyapatite (HAP) was isolated from the bones of sea bass (Lates calcarifer) fish by thermal calcination at 800°C. HAP-chitosan-coir pith composite prepared with HAP, chitosan and coir pith. The characterized using thermogravimetric analysis (TG), differential (DTA), Fourier Transformed Infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive (EDX). crystalline compressive strength 13.96 ± 0.95 MPa, tensile 1.51 0.74...

The aim of this study was to compare the various dosimetric parameters dynamic multileaf collimator (MLC) intensity modulated radiation therapy (IMRT) plans with volumetric arc (VMAT) for base tongue cases. All were done in Monaco planning system Elekta synergy linear accelerator 80 MLC. IMRT planned nine stationary beams, and VMAT 360° single or dual arc. dose target volumes (PTV) 70, 63, 56 Gy compared. 95, 98, 50% volume PTV analyzed. homogeneity index (HI) conformity (CI) ₇₀...

The development of practical sensors for the detection and quantification heavy metals ions in samples is subject considerable research. A glutathione stabilized silver nanoparticles (GSH-AgNPs) modified screen printed electrode was proposed to determine trace levels Pb(II) by using cyclic voltammetry. Maximum current obtained at potential range 0.263 V. electrostatic redox peak shows a linear response towards concentration calibration curves were obtained. limit determined as 4.963×10 <sup...

Metal–organic complexes have shown astounding bioactive properties; however, they are rarely explored as biomaterials. Recent studies showed that carboxymethyl-chitosan (CMC) genipin-conjugated zinc biomimetic scaffolds unique bioselective properties. The biomaterial was reported to be mammalian cell-friendly; at the same time, it found discourage microbial biofilm formation on its surface, which seemed a promising solution addressing problem of trauma-associated and development...

To measure and compare the head scatter factor for flattened (FB) unflattened (FFF) of 6MV 10MV photon beam using indigenously designed mini phantom. A columnar phantom was as recommended by AAPM Task Group 74 with low high atomic number materials at 10 cm (mini phantom) approximately twice depth maximum dose water equivalent thickness (brass build-up cap). Scatter in accelerator (Sc) values 6MV-FFF beams are lesser than that 6MV-FB (0.66-2.8%; Clinac iX, 2300CD) (0.47-1.74%; True beam)...

The purpose of this study is to verify the accuracy commissioning intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc (VMAT) based on recommendation American Association Physicists in Medicine Task Group 119 (TG-119).TG-119 proposes a set clinical test cases IMRT planning delivery system. For these cases, we generated two sets treatment plans, first plan using 7-9 fields second utilizing two-arc VMAT technique for both 6 MV 15 photon beams. template plans TG-119 were...
