Authors: M R, S V, Ramirez JT, A V, L L Abstract Novel materials are explored very often by material scientists to design an efficient drug delivery system to target carcinoma cells. Among various nanosystem, functionalized Iron oxide Nanoparticles (IoNP) were definitely studied especially to target, endocyte and release drug moieties inside the cells. This IoNP platform is usually composed of an inorganic core and a highly biocompatible shell layer in order to perform numerous tasks at the same time, such as drug delivery, multimodal imaging, and instantaneous monitoring, along with collective therapeutic approach...

In this study, the chemically crosslinked hydrogels of carboxymethyl chitosan and polyvinyl alcohol were fabricated by the free radical polymerization. Successful polymerization was confirmed by Fourier transform infrared spectroscopy, while x-ray diffraction, thermogravimetric analysis, and differential scanning calorimetric measurements helped in investigating crystallinity and thermal behavior of the products. Morphological characterization was performed by scanning electron microscopy. The increased incorporation of carboxymethyl chitosan and polyvinyl alcohol enhanced the swelling, drug loading, and in-vitro drug rele...

ConclusionsThe present study describes the development of an image analytic module for assessing tumor growth rate and the data demonstrates the functionality and reproducibility of the module in a pilot cohort of EGFR-mutant NSCLC patients treated with EGFR-TKI. The image analytic module is an initial step for clinical translation of the tumor growth rate approach to guide cancer treatment in precision oncology.

PEGylated Poly(α-lipoic acid) Loaded with Doxorubicin as a pH and Reduction Dual Responsive Nanomedicine for Breast Cancer Therapy. Biomacromolecules. 2018 Oct 22;: Authors: Yang H, Shen W, Liu W, Chen L, Zhang P, Xiao C, Chen X Abstract Disulfide-containing nanoparticles are promising vehicles for anticancer drug delivery. However, the preparation of disulfide-containing nanoparticles usually relies on complex synthetic procedures. In the present work, a PEGylated poly(α-lipoic acid) (mPEG-PαLA) copolymer was facilely synthesized and used for pH and reduction dual responsive drug de...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

bin Yin Jian Ni Sustained-release preparation is a hot spot in antitumor drug research, where the first task is to select suitable drug carriers. Research has revealed that carboxylic acid iron metal–organic frameworks (MOFs), constructed from iron (Fe) ions and terephthalic acid, are nontoxic and biocompatible. Due to the breathing effect, the skeleton of this mesoporous material is flexible and can reversibly adapt its pore size through drug adsorption. Therefore, we chose one kind of Fe-MOF, MIL-53(Fe), as a carrier for the anticancer drug oridonin (Ori). In this work, we report the design and synthesis ...

Publication date: 1 January 2019Source: Materials Science and Engineering: C, Volume 94Author(s): Lijun You, Xiaocui Liu, Zhexiang Fang, Qianhui Xu, Qiqing ZhangAbstractA new folic acid (FA)-conjugated poly (lactic-co-glycolicacid) (PLGA)-polyethylene glycol (PEG) nano-noisome was prepared. The noisome was employed as a drug delivery system to load curcumin (Cur) as a model drug and fluorescent probe for cervical cancer therapy and cell imaging. The Fe3O4@PLGA-PEG@FA noisomes were prepared through facile emulsion solvent evaporation and conjugation chemistry method, possessing the properties of high rapid magnetic separati...

AbstractPurpose of ReviewLung cancer is increasingly a disease of the elderly. Historically, the information on how best to treat these patients is scant, but over recent years, there have been increasing data to support both systemic and targeted treatment as would be offered to younger patients. This paper aims to summarise the considerations behind this.Recent FindingsThe introduction of a screening tool to help understand the overall health of patients will ensure that older cancer patients are considered for all active anti-cancer therapies. These geriatric assessment tools include several important domains such as nu...

Scientists at the Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) have developed a method implemented as pulse sequences and software to be used with magnetic resonance imaging (MRI) scanners and systems. This technology is available for licensing and commercial development. The method allows for measuring and mapping features of the bulk or average apparent diffusion coefficient (ADC) of water in tissue – aiding in stroke diagnosis and cancer therapy assessment. The pulse sequences and software enable MRI scanners to yield diffusion weighted images (DWI) that are orientationa...
