  The combination of EGFR-TKI and radiotherapy might carry a risk of pneumonitis; however, there are limited data concerning dose constraints. Our results showed a slightly higher incidence of mild or moderate radiation pneumonitis by strict dose limitation.

Such structures have two metal/dielectric interfaces to allow interaction between the gold metal with the interior and external dielectric environment. Upon illumination by light, HGNs exhibit unique surface plasmon resonance (SPR) properties compared to solid gold nanoparticles. Their SPR absorption/scattering can be tuned by changing their diameter, shell thicknesses, and surface morphologies. In addition to the low toxicity, easy functionalization, resistance to photobleaching, and sensitivity to changes in surrounding medium of gold, the enhanced surface-to-volume ratio and tunable SPR of HGNs make them highly attractive for different applications in the fields of sensing, therapy, and theranostics. In this article, we review recent progress on the synthesis and structural control of HGNs and applications of their SPR properties in biomedical sensing and theranostics.

  Diagnosis delay in children and adolescents with cancer is a public health problem in Peru that leads to high rates of advanced disease and mortality. We aimed to assess the implementation feasibility and potential utility of ONCOpeds®, a mobile application that provides consultations with pediatric oncologists, in reducing the latency to diagnosis (LD) and referral time (RT) among children and adolescents in Peru diagnosed with cancer.
 
  A prospective pilot study was conducted in the region of Callao between November 2017 and April 2018. Primary and secondary care providers were trained on the use of ONCOpeds in five educational sessions.  https://www.selleckchem.com/products/tak-981.html  Patients younger than 18 years who resided in Callao and were diagnosed with cancer at four pediatric cancer units in Lima were analyzed by referral type ONCOpeds facilitated or conventional.
 
  ONCOpeds was successfully installed in the smartphones of 78 primary and secondary care providers of Callao. During the study period, 23 new cases of cancer in children and adolescents from the region were diagnosed. Ten patients received ONCOpeds-facilitated referrals and 13 received conventional referrals. The RT decreased among those who received ONCOpeds-facilitated referrals by 66% (P=0.02); however, the LD did not significantly decrease with the use of ONCOpeds.
 
  The implementation of ONCOpeds was found to be feasible in this pilot study, having a potential utility in improving early diagnosis and referral in children and adolescents newly diagnosed with cancer. Directions for future research include multicenter studies with a larger population to further test the application's effectiveness.

We found that most Rb survivors adhered to general population cancer screening recommendations. Rates did not differ among Rb survivors and non-Rb controls, or among survivors by laterality, even though bilateral survivors reported higher levels of concern about future health and cancer risk. Older age, being overweight/obese, and lack of recent contact with medical personnel were independently associated with decreased utilization of Pap smear among female Rb survivors. Future studies are warranted to determine whether these associations might provide an opportunity for intervention.Extramedullary plasmacytoma (EMP) is a rare plasma cell tumor involving the organs but without bone marrow involvement or the characteristics of multiple myeloma. Primary solitary endobronchial plasmacytoma is extremely rare. Here we present the case of an 86-year-old male ex-smoker who visited our outpatient clinic for an endobronchial mass in the left upper lobe of the lung. Fiberoptic bronchoscopy revealed a protruding mass in the left upper lobar bronchus; based on the bronchoscopic biopsy findings, a primary solitary endobronchial plasmacytoma was diagnosed. After radiation therapy the patient was well and 6 months after treatment showed no evidence of disease recurrence. Extramedullary plasmacytoma should be considered in the differential diagnosis of an endobronchial mass.This study was performed to evaluate the antioxidant, anticancer, and toxicity properties of ferutinin, a phytoestrogen derived from Ferula species. The human Michigan Cancer Foundation-7 (MCF-7) breast cancer cell line and normal human fibroblast (HDF) were cultured and treated with different ferutinin concentrations. The cell viability was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell death-defining tests (a comparative real-time polymerase chain reaction [for Bax and Bcl-2 genes], flow cytometry, and acridine orange/propidium iodide cell staining). Moreover, 15 white male balb/c mice were divided into three groups of five (one untreated control group and two groups), which received different doses of ferutinin-supplemented water (500 and 1000 µg/kg mice weight) to check the mice liver and kidney pathomorphological alterations and to determine the antioxidant enzymes' expression profile (superoxide dismutase [SOD], catalase [CAT], and glutathione peroxidase) in the mentioned tissues.
