2Calcium signaling and T-type calcium channels in cancer cell cycling显示文摘Regulation of intracellular calcium is an important signaling mechanism for cell proliferation in both normal and cancerous cells. In normal epithelial cells, free calcium concentration is essential for cells to enter and accomplish the S phase and the M phase of the cell cycle. In contrast, cancerous cells can pass these phases of the cell cycle with much lower cytoplasmic free calcium concentrations, indicating an alternative mechanism has developed for fulfilling the intracellular calcium requirement for an increased rate of DNA synthesis and mitosis of fast replicating cancerous cells. The detailed mechanism underlying the altered calcium loading pathway remains unclear; however, there is a growing body of evidence that suggests the T-type Ca2+ channel is abnormally expressed in cancerous cells and that blockade of these channels may reduce cell proliferation in addition to inducing apoptosis. Recent studies also show that the expression of T-type Ca2+ channels in breast cancer cells is proliferation state dependent, i.e. the channels are expressed at higher levels during the fast-replication period, and once the cells are in a non-proliferation state, expression of this channel isminimal. Therefore, selectively blocking calcium entry into cancerous cells may be a valuable approach for preventing tumor growth. Since T-type Ca2+ channels are not expressed in epithelial cells, selective T-type Ca2+ channel blockers may be useful in the treatment of certain types of cancers.James T Taylor Xiang-Bin Zeng Jonathan E Pottle Kevin Lee Alun R Wang Stephenie G Yi lennifer A S Scruggs Suresh S Sikka Ming Li 2008World Journal of Gastroenterology2008,14,32:12
3Potentiation of NETs release is novel characteristic of TREM-1 activation and the pharmacological inhibition of TREM-1 could prevent from the deleterious consequences of NETs release in sepsis显示文摘During sepsis,neutrophil activation induces endothelial cell(EC)dysfunction partly through neutrophil extracellular trap(NET)release.The triggering receptor expressed on myeloid cell-1(TREM-1)is an orphan immune receptor that amplifies the inflammatory response mediated by Toll-like receptor-4(TLR4)engagement.Although the key role of TLR4 signaling in NETosis is known,the role of TREM-1 in this process has not yet been investigated.Here,we report that TREM-1 potentiates NET release by human and murine neutrophils and is a component of the NET structure.In contrast,pharmacologic inhibition or genetic ablation of TREM-1 decreased NETosis in vitro and during experimental septic shock in vivo.Moreover,isolated NETs were able to activate ECs and impair vascular reactivity,and these deleterious effects were dampened by TREM-1 inhibition.TREM-1 may,therefore,constitute a new therapeutic target to prevent NETosis and associated endothelial dysfunction.Amir Boufenzer Kevin Carrasco Lucie Jolly Benjamin Brustolin Elisa Di-Pillo Marc Derive Sébastien Gibot 2021Cellular & Molecular Immunology2021,18,2:9
4Role of interventional radiology in the management of acute gastrointestinal bleeding显示文摘Acute gastrointestinal bleeding(GIB) can lead to significant morbidity and mortality without appropriate treatment. There are numerous causes of acute GIB including but not limited to infection, vascular anomalies, inflammatory diseases, trauma, and malignancy. The diagnostic and therapeutic approach of GIB depends on its location, severity, and etiology. The role of interventional radiology becomes vital in patients whose GIB remains resistant to medical and endoscopic treatment. Radiology offers diagnostic imaging studies and endovascular therapeutic interventions that can be performed promptly and effectively with successful outcomes. Computed tomography angiography and nuclear scintigraphy can localize the source of bleeding and provide essential information for the interventional radiologist to guide therapeutic management with endovascular angiography and transcatheter embolization. This review article provides insight into the essential role of Interventional Radiology in the management of acute GIB.Raja S Ramaswamy Hyung Won Choi Hans C Mouser Kazim H Narsinh Kevin C McCammack Tharintorn Treesit Thomas B Kinney 2014World Journal of Radiology2014,6,4:8
5睾酮与男性心血管疾病显示文摘尽管冠状动脉疾病(CAD)的发病存在地域差异,但相对于女性,男性的CAD发病及死亡率还是较高。性激素的性别特异性影响起着一定的作用。本文对目前睾酮在男性CAD中起的作用进行了概述,包括年龄相关的睾酮下降,睾酮水平与CAD、CAD风险因子和死亡率之间的关系。同时我们也论述了睾酮的血管活性作用,并讨论了其在心衰和心绞痛男性病人中的应用。我们还讨论了CAD男性病人的低睾酮水平是其“缘由”还是“影响”的争议,以及用睾酮补充疗法治疗中老年男性的各种顾虑。文章最后提出了此领域未来研究的方向,包括用睾酮补充疗法治疗男性CAD病人及其优缺点等。Paul D Morris Kevin S Channer 2012Asian Journal of Andrology2012,14,3:8
6A review of UHMWPE wear-induced osteolysis:the role for early detection of the immune response显示文摘In a world where increasing joint arthroplasties are being performed on increasingly younger patients,osteolysis as the leading cause of failure after total joint arthroplasty(TJA) has gained considerable attention.Ultra-high molecular weight polyethylene wear-induced osteolysis is the process by which prosthetic debris mechanically released from the surface of prosthetic joints induces an immune response that favors bone catabolism, resulting in loosening of prostheses with eventual failure or fracture. The immune response initiated is innate in that it is nonspecific and self-propagating, with monocytic cells and osteoclasts being the main effectors. To date, detecting disease early enough to implement effective intervention without unwanted systemic side effects has been a major barrier. These barriers can be overcome using newer in vivo imaging techniques and modules linked with fluorescence and/or chemotherapies. We discuss the pathogenesis of osteolysis, and provide discussion of the challenges with imaging and therapeutics. We describe a positron emission tomography imaging cinnamoyl-Phe-(D)-Leu-Phe-(D)-Leu-Phe-Lys module,specific to macrophages, which holds promise in early detection of disease and localization of treatment.Further research and increased collaboration among therapeutic and three-dimensional imaging researchers are essential in realizing a solution to clinical osteolysis in TJA.Adrese M Kandahari Xinlin Yang Kevin A Laroche Abhijit S Dighe Dongfeng Pan Quanjun Cui 2016Bone Research2016,4,2:7
7Tumor Antigen Specific Activation of Primary Human T-Cells Expressing a Virally Encoded Chimeric T-Cell Receptor Specific for p185HER2显示文摘We have developed and tested chimeric T-cell receptors (TCR) specific for p185HER2. In these experiments, retroviral vectors expressing the N29γ or N29ζ receptors were constructed in pRET6. Amphotropic viral producer cells were established in the GALV-based PG13 packaging cell line. Ficoll purified human peripheral blood lymphocytes (PBL) were virally transduced using an optimized protocol incorporating activation with immobilized anti-CD3/anti-CD28 monoclonal anti- bodies, followed by viral infection in the presence of fibronectin fragment CH296. Transduced cells were co-cultured with human tumor cell lines that overexpress (SK-OV-3) or underexpress (MCF7) p185HER2 to assay for antigen specific im- mune responses. Both CM+ and CD8+ T-cells transduced with the N29γ or N29ζ chTCR demonstrated HER2-specific anti- gen responses, as determined by release of Th1 like cytokines, and cellular cytotoxicity assays. Our results support the fea- sibility of adoptive immunotherapy with genetically modified T-cells expressing a chTCR specific for p185HER2.杨建民 Michael S FRIEDMAN Christopher M REYNOLDS Marianne T HUBEN Lee WILKE Jennifer FULLER 李桥 Zelig ESHHAR James J MULE Kevin T MCDONAGH 2004Journal of Microbiology and Immunology2004,2,4:5

9Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage显示文摘AIM:To describe the prevalence,diagnosis,treatment,and outcomes of end stage liver disease(ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage(UGIH).METHODS:This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011.RESULTS:A total of 1249 patients were registered for severe UGIH in the data basis,461(36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen(75%) subjects required posterior nasal packing and 2(10%) embolization in addition to correction of coagulopathy. Five(25%) patients died in the hospital,12(60%) received orthotopic liver transplantation(OLT),and 3(15%) were discharged without OLT. The mortality rate was 63% in patients without OLT.CONCLUSION:Severe epistaxis in patients with ESLD is(1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH;and(2) associated with a high mortality rate in patients not receiving OLT.Marine Camus Dennis M Jensen Jason D Matthews Gordon V Ohning Thomas O Kovacs Rome Jutabha Kevin A Ghassemi Gustavo A Machicado Gareth S Dulai 2014World Journal of Gastroenterology2014,20,38:3
10Accuracy of biometric formulae for intraocular lens power calculation in a teaching hospital显示文摘AIM: To evaluate the accuracy of three commonly used biometric formulae across different axial lengths(ALs) at one United States Veterans Affairs teaching hospital.METHODS: A retrospective chart review was conducted from November 2013 to May 2018. One eye of each patient who underwent cataract surgery with a monofocal intraocular lens(IOL) was included. The range of postoperative follow-up period was from 3 wk to 4 mo. The Holladay 2, Barrett Universal II, and Hill-Radial Basis Function(Hill-RBF) formulae were used to predict the postoperative refraction for all cataract surgeries. For each formula, we calculated the prediction errors [including mean absolute prediction error(MAE)] and the percentage of eyes within ±0.25 diopter(D) and ±0.5 D of predicted refraction. We performed subgroup analyses for short(AL<22.0 mm), medium(AL 22.0-25.0 mm), and long eyes(AL>25.0 mm).RESULTS: A total of 1131 patients were screened, and 909 met the inclusion criteria. Resident ophthalmologists were the primary surgeons in 710(78.1%) cases. We found no statistically significant difference in predictive accuracy among the three formulae over the entire AL range or in the short, medium, and long eye subgroups. Across the entire AL range, the Hill-RBF formula resulted in the lowest MAE(0.384 D) and the highest percentage of eyes with postoperative refraction within ±0.25 D(42.7%) and ±0.5 D(75.5%) of predicted. All three formulae had the highest MAEs(>0.5 D) and lowest percentage within ±0.5 D of predicted refraction(<55%) in short eyes.CONCLUSION: In cataract surgery patients at our teaching hospital, three commonly used biometric formulae demonstrate similar refractive accuracy across all ALs. Short eyes pose the greatest challenge to predicting postoperative refractive error.Kevin S Tang Elaine M Tran Allison J Chen David R Rivera Jorge J Rivera Paul B Greenberg 2020International Journal of Ophthalmology(English edition)2020,13,1:3

12In vivo anti-tumor activity of murine hematopoietic stem cells expressing a p185HER2-specific chimeric T-cell receptor gene显示文摘We have confirmed efficient anti-tumor activities of the peripheral lymphocytes transduced with a p185HER2-specific chimeric T-cell receptor gene both in murine and in human in our previous studies. To further test the feasibility of chimeric T-cell receptor in a bone marrow transplantation model, we first, made two murine tumor cell lines: MT901 and MCA-205, to express human p185HER2 by retroviral gene transduction. Murine bone marrow cells were retrovirally transduced to express the chimeric T-cell receptor and gene-modified bone marrow cells were transplanted into lethally irradiated mouse. Six months post transplantation, p185HER2-positive tumor cells:MT-901/HER2 or MCA-205/ HER2 was subcutaneously or intravenously injected to make mouse models simulating primary breast cancer or pulmonary metastasis. The in vivo anti-tumor effects were monitored by the size of the subcutaneous tumor or counting the tumor nodules in the lungs after India ink staining. The size of the subcutaneous tumor was significantly inhibited and the number of pulmonary nodules were significantly decreased in mouse recipients transplanted with chimeric T-cell receptor modified bone marrow cells compared with the control group. Our results suggest the efficient in vivo anti-tumor activities of chimeric T-cell receptor gene modified bone marrow cells.JIAN MIN YANG MICHAEL S FRIEDMAN MARIANNE T HUBEN JENNIFER FULLER QIAO LI ALFRED E CHANG JAMES J MULE KEVIN T MCDONAGH 2006Journal of Microbiology and Immunology2006,4,2:3
