Abstract
Realizing precise therapy for glioblastomas (GBMs), a kind of high-frequency malignant brain tumor, is of great importance in improving the overall survival (OS) of patients. With relentless efforts made in the past few years, a sponge medium has been introduced into concurrent tumor treating fields (TTFields) and radiotherapy to enhance therapy efficacy for GBMs, and some progresses have been witnessed. However, the specific physical and chemical characteristics of the sponge that can be used for GBMs have not been reported as far as we know. Therefore, this study aims to develop a simple yet robust method to select a candidate sponge medium and verify its safety in advanced concurrent TTFields and radiotherapy for GBMs through interdisciplinary investigation among materials science, medical physics, and clinical radiation oncology. Significantly, latex-free polyurethane (PU) sponges with a Hounsfield unit (HU) value lower than -750, which exhibit almost no negative influence on planning computed tomography (CT) imaging and radiotherapy dosimetry, are demonstrated to be available for concurrent TTFields and radiotherapy for GBMs. Moreover, in clinical research, the achieved clear CT images, negligible scalp toxicity, lower residual positioning errors, and high compliant rate of 82% over the selected representative sponge sample corroborate the availability and safety of PU sponges in practical applications for GBM treatment.

Chitosan-acrylate nanogel for durable anti mosquito finishing of cotton fabric and its dermal toxicity profiling on Swiss albino mice. Colloids Surf B Biointerfaces 2019; 181:789-797.

Abstract
Chitosan nanocapsules, containing lemongrass (Cymbopogon citratus) oil (LGO), have been developed in gel form in which acrylate (Ac) was incorporated as a thickener and fabric binder. The gel was impregnated on fabric to achieve long-lasting and wash-durable mosquito repellency. The interaction between cotton fibers and gel was investigated by FTIR and XRD. Wash durability of gel was compared with chitosan nanocapsules without acrylate (LGO-encap) using SEM and GC-MS. The SEM analyses revealed that acrylate containing nanocapsules retains on fabric after a series of washing. The GC-MS results indicated that the relative amount of deducible oil components from fabric was found to be higher after the series of washing in acrylate containing nanocapsules (LGO-encap-Ac), which further points to the improved wash durability and retention of capsules on fabric. The bio-efficacy results of post-fifteen washing turned out was 75% of repellency against mosquitoes with the use of acrylate; while in nanocapsules without acrylate, only 51% of repellency was achieved. Furthermore, the 36 days repeated application of nanogel on Swiss albino mice did not show any signs of dermal toxicity. The formulation is, thus, suitable to impregnate dress of the military personals and individuals who have to perform field duty and where risk of mosquito bites is probably more.

Abstract
Polyurethane acrylate (PUA) from vegetable oil has been synthesized and prepared for solid polymer electrolyte. Polyol has been end-capped with Toluene 2,4-Diisocyanate (TDI) followed by hydroxylethylmethylacrylate (HEMA) in a urethanation process to produce PUA. The mixtures were cured to make thin polymeric films under UV radiation to produce excellent cured films which exhibit good thermal stability and obtain high ionic conductivity value. 3 to 15 wt. % of ethylene carbonate (EC) mixed with 25 wt. % LiClO₄ was added to PUA to obtain PUA electrolyte systems. PUA modified with plasticizer EC 9 wt. % achieved the highest conductivity of 7.86 × 10-4 S/cm, and relatively improved the linear sweep voltammetry, transference number and dielectric properties. Fourier Transform Infrared Spectroscopy (FTIR) and dielectric analysis were presented. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), followed by X-ray Diffraction (XRD) and morphology have been studied. The addition of plasticizer to the polyurethane acrylate shows significant improvement in terms of the conductivity and performance of the polymer electrolyte.
