https://www.readbyqxmd.com/read/29766832/northstar-perspectives-for-actinium-225-production-at-commercial-scale
#1
James T Harvey
Actinium-225, and its daughter bismuth-213, have great promise in alpha immuno therapy (AIT) for treatment of various disease modalities. Unfortunately, current production levels of actinium-225 that are commercially available do not support broad use of either actinium-225 or bismuth-213 in development or use for disease treatment. Further, the current cost per millicurie is much too high to be sustainable long term in the market. Resolution of both supply and cost issues allows clinical research to proceed through clinical trials and potentially produce one or more effective therapies for cancer or infectious diseases that could benefit the public...

Lin Wang, Yonggan Niu, Hui Zhang, Baokai Li
BACKGROUND: Reinforcement of lower lateral crura (LLC) is an imperative prophylaxis against the secondary deformity of alar and nasal tip in Asian rhinoplasty. The common limitation of the existing techniques is loss of nasal tip's mobility to a large degree in exchange for structural stability. In search for a natural and animated postoperative nasal tip, the elasticity and rigidity of coastal periphery was taken into account. METHOD: Two pieces of sliced costal periphery (SCP) were used to reinforce the LLC...

Laparoscopic liver resection (LLR) has garnered attention as a new form of liver surgery. In China, many hepatobiliary surgeons are now encouraging the examination and assessment of LLC in order to improve its outcomes, and several young hepatobiliary surgeons recently shared their clinical experiences and the results of their research in presentations at the Akamon Forum as part of the 118th Annual Congress of the Japan Surgical Society, which was held April 5-7, 2018 in Tokyo, Japan. In China, LLR has gradually improved over the past 20 years, including both expanded indications and improved surgical approaches...

The activity of negative immune regulatory molecules, such as indoleamine 2,3-oxygenase (IDO), significantly attenuates DC (Dendritic cells)-mediated immunotherapy. We have previously reported that knockdown of IDO using siRNA can reinstall anti-tumor immunity. However, a DC-targeted siRNA delivery system for in vivo mobilized DCs remains to be developed, while gene silencing in mobilized DCs for cancer immunotherapy has never been explored. In this study, we developed a novel DC-targeted siRNA delivery system, man-GNR-siIDO, using as a nanocarrier of siRNA specific for IDO (siIDO) and mannose (man) as a guide molecule for targeting DCs...

Dihydroartemisinin (DHA), a semi-synthetic derivative of artemisinin isolated from the traditional Chinese herb Artemisia annua , is an effective novel antimalarial agent. Studies have suggested that it also exhibits anticancer effects when administered alone or in combination with conventional chemotherapeutic agents. The present study investigated the therapeutic effect of DHA combined with carboplatin (CBP) on Lewis lung carcinoma (LLC) cells and the possible underlying molecular mechanisms. MTT and clonogenic assays demonstrated that the proliferation activity of LLC cells was inhibited in a dose-dependent manner by DHA combined with CBP...

Preventive effects and corresponding molecular mechanisms of mugwort ( Artemisia argyi ) extract and its flavonoid constituents on contrast-induced nephrotoxicity were explored in the present study. We treated cultured LLC-PK1 cells with iodixanol to induce contrast-induced nephrotoxicity, and found that A. argyi extracts ameliorated the reduction in cellular viability following iodixanol treatment. The anti-apoptotic effect of A. argyi extracts on contrast-induced nephrotoxicity was mediated by the inhibition of mitogen-activated protein kinase (MAPK) phosphorylation and the activation of caspases...

BACKGROUND: As survival following treatment for symptomatic spinal metastases increases, the incidence of local tumor recurrence may also increase. However, data regarding incidence and timing of recurrence, or duration of survival after second surgeries are not readily available, and may help to inform clinicians when to perform second surgeries. OBJECTIVE: To identify features associated with loss of local control (LLC) at a previously treated or new spinal level...

Although previous studies have demonstrated that dysregulation of microRNA (miR)-126 is associated with the progression of several types of cancer, including lung cancer, the relationship between miR-126 and lung cancer metastasis remains unclear. SPC-A1 lung cancer cells were transfected with miR-126 mimic and negative control using Lipofectamine® 3000. Following 2 h, TGF-β1 was used to induce epithelial-to-mesenchymal transition (EMT). The protein expression levels of EMT markers: E-cadherin, fibronectin, N-cadherin and vimentin were detected by western blot analysis or immunofluorescence staining...

Nanoparticulate anti-tumor photodynamic therapy (PDT) has been suffering from the limited dose accumulation in tumor. Herein, we report dually hypoxia- and singlet oxygen-responsive polymeric micelles to efficiently utilize the photosensitizer deposited in the disease site and hence facilely improve the therapeutic efficacy of PDT. Tailored methoxy poly(ethylene glycol)-azobenzene-poly(aspartic acid-imidazole) copolymer conjugate was synthesized. The self-assembled conjugate micelles (189 ± 19 nm) could efficiently load a model photosensitizer, chlorin e6 (Ce6) with a loading of 4...

Lung-specific overexpression of prostacyclin synthase (PGIS) decreases tumor initiation in murine lung cancer models. Prostacyclin analogs prevent lung tumor formation in mice and reverse bronchial dysplasia in former smokers. However, the effect of prostacyclin on lung cancer progression has not been well studied. We investigated the effects of pulmonary PGIS overexpression in an orthotopic immunocompetent mouse model of lung cancer using two murine lung cancer cell lines. Pulmonary PGIS overexpression significantly inhibited CMT167 lung tumor growth, increased CXCL9 expression, and increased CD4+ tumor-infiltrating lymphocytes...

Under diabetic conditions, sodium-glucose cotransporter 2 (SGLT2) for glucose uptake in proximal tubules (PTs) increases, whereas NAD+ -dependent protein deacetylase silent mating type information regulation 2 homolog 1 (Sirtuin-1; SIRT1) for PT survival decreases. Therefore, we hypothesized that increased glucose influx by SGLT2 reduces SIRT1 expression. To test this hypothesis, db/db mice with diabetes and high-glucose (HG)-cultured porcine PT LLC-PK1 cells in a two-chamber system were treated with the SGLT2 inhibitor canagliflozin...

BACKGROUND: Suitable and scalable in vitro culture conditions for parasite maintenance are needed to foster drug research for loiasis, one of the neglected tropical diseases which has attracted only limited attention over recent years, despite having important public health impacts. The present work aims to develop adequate in vitro culture systems for drug screening against both microfilariae (mf) and infective third-stage larvae (L3) of Loa loa. METHODS: In vitro culture conditions were evaluated by varying three basic culture media: Roswell Park Memorial Institute (RPMI-1640), Dulbecco's modified Eagle's medium (DMEM) and Iscove's modified Dulbecco's medium (IMDM); four sera/proteins: newborn calf serum (NCS), foetal bovine serum (FBS), bovine serum albumin (BSA) and the lipid-enriched BSA (AlbuMax® II, ALB); and co-culture with the Monkey Kidney Epithelial Cell line (LLC-MK2) as a feeder layer...

Trypanosoma cruzi , the aetiologic agent of Chagas disease, releases vesicles containing a wide range of surface molecules known to affect the host immunological responses and the cellular infectivity. Here, we compared the secretome of two distinct strains (Y and YuYu) of T. cruzi , which were previously shown to differentially modulate host innate and acquired immune responses. Tissue culture-derived trypomastigotes of both strains secreted extracellular vesicles (EVs), as demonstrated by electron scanning microscopy...
