Sonication tailored enhance cytotoxicity of naringenin nanoparticle in pancreatic cancer: Design, optimization, and in vitro studies. Drug Dev Ind Pharm. 2020 Mar 25;:1-41 Authors: Akhter MH, Kumar S, Nomani S Abstract Objective: In vitro, optimization, characterization and cytotoxic studies of NAR NPs to against pancreatic cancer.Method: The sonication tailored NARG loaded poly (lactide-co-glycolic acid) (PLGA) nanoparticle (NPs) was fabricated for potential cytotoxic effect against pancreatic cancer. NARG NPs were prepared by emulsion-diffusion evaporation technique applying Box Behnken experimental design based on 3-level and 3-factors. The effect of independent variables surfactant concentration (X1), polymer concentration (X2) and sonication time (X3) were studied on responses particle size (Y1), and drug release % (Y2). NPs characterized for particles size and size distribution, polydispersity index (PDI), zeta potential, transmission electron microscope (TEM), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), Differential scanning calorimeter (DSC), and X-ray diffraction (XRD) studies. Further, the studies was fitted to various drug release kinetic model and cytotoxicity evaluated in vitro.Results: The nanosized particles were spherical, uniform with an average of size of 150.45 ± 12.45 nm, PDI value 0.132 ± 0.026, zeta potential of -20.5 ± 2.5&...
CONCLUSION: In conclusion, the synthesized nanoparticles from D. microcarpum leaves (dAgNps) have inhibitory effect on pancreatic and cervical cancer cells. PMID: 32458629 [PubMed - in process]
Conclusions: IRE combined with radiotherapy or chemotherapy was superior to IRE alone for the treatment of LAPC, as it prolonged the survival time and improved the survival rate, making it worthy of wide dissemination and clinical application.
ConclusionsHypoxia modulation may play a role in nal-IRI ’s mechanism of action. Nal-IRI demonstrated greater anti-tumor activity in the more aggressive and hypoxic tumor model. Furthermore, hypoxia imaging provided early prediction of treatment response.
Conclusions: Although bevacizumab caused atrophy of the pancreas and reduced pancreatic volume, pancreatic endocrine function showed no change. Future studies should investigate the survival rate and functional changes caused by bevacizumab treatment. PMID: 32432961 [PubMed - as supplied by publisher]
rian M. Zeglis High expression levels of the tumor-associated antigen MUC1 have been correlated with tumor aggressiveness, poor response to therapy, and poor survival in several tumor types, including breast, pancreatic, and epithelial ovarian cancer. Herein, we report the synthesis, characterization, and in vivo evaluation of a novel radioimmunoconjugate for the immuno-positron emission tomography (immunoPET) imaging of MUC1 expression based on the AR20.5 antibody. To this end, we modified AR20.5 with the chelator desferrioxamine (DFO) and labeled it with the positron-emitting radiometal zirconium-89 (t1/2 ~3.3 d) to ...
Conclusions Mortality is a poor proxy for cancer diagnosis for treatable cancers and not the optimal outcome measure in etiological studies. Although the HR prese nted here handle bias from the healthy worker hire effect and left truncation, they do not handle bias from healthy worker survivor effect, which likely results in underestimates of the health impacts of MWF. Although this updated summary provides some information on the risk of cancer from MWF, tar geted future analyses will help clarify associations.byCostello S, Chen K, Picciotto S, Lutzker L, Eisen E. doi:10.5271/sjweh.3899

Authors: Araç E, Can C, Kömek H Abstract OBJECTIVE: The present study compared metabolic and volumetric fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) parameters [metabolic tumour volume (MTV), total lesion glycolysis (TLG), and maximum standardized uptake value (SUVmax)] with carbohydrate antigen (CA) 19-9 tumour marker levels and haemogram parameters [(neutrophil-lymphocyte ratio, mean platelet volume (MPV), and platelet-lymphocyte ratio] as prognostic and diagnostic markers of pancreatic cancer. MATERIAL AND METHODS: A total of 66 patients who u...
son SM Abstract PURPOSE: 124I-PU-H71 is an investigational first-in-class radiologic agent specific for imaging tumor epichaperome formations. The intracellular epichaperome forms under cellular stress and is a clinically validated oncotherapeutic target. We conducted a first-in-human study of microdose 124I-PU-H71 for positron emission tomography (PET) to study in vivo biodistribution, pharmacokinetics, metabolism, and safety; and the feasibility of epichaperome-targeted tumor imaging. EXPERIMENTAL DESIGN: Adult patients with cancer (n=30) received 124I-PU-H71 tracer (201±12 MBq,
CONCLUSION: Organ-matching may be a better setup correction technique than BM for both photon therapy and IMPT plans. However, in some beam arrangements of IMPT, the dose distribution may be somewhat worse using OM, due to interfractional anatomical variation. Therefore, it is important to choose beam angles that are less likely to be influenced by changes in the gastrointestinal gas volume, especially in IMPT plans.
