| 1 | Endoscopy and polyps-diagnostic and therapeutic advances in management显示文摘Despite multiple efforts aimed at early detection through screening, colon cancer remains the third leading cause of cancer-related deaths in the United States, with an estimated 51000 deaths during 2013 alone. The goal remains to identify and remove benign neoplastic polyps prior to becoming invasive cancers. Polypoid lesions of the colon vary widely from hyperplastic, hamartomatous and inflammatory to neoplastic adenomatous growths. Although these lesions are all benign, they are common, with up to one-quarter of patients over 60 years old will develop pre-malignant adenomatous polyps. Colonoscopy is the most effective screening tool to detect polyps and colon cancer, although several studies have demonstrated missed polyp rates from 6%-29%, largely due to variations in polyp size. This number can be as high as 40%, even with advanced (> 1 cm) adenomas. Other factors including sub-optimal bowel preparation, experience of the endoscopist, and patient anatomical variations all affect the detection rate. Additional challenges in decision-making exist when dealing with more advanced, and typically larger, polyps that have traditionally required formal resection. In this brief review, we will explore the recent advances in polyp detection and therapeutic options. | Scott R Steele Eric K Johnson Bradley Champagne Brad Davis Sang Lee David Rivadeneira Howard Ross Dana A Hayden Justin A Maykel | 2013 | World Journal of Gastroenterology2013,19,27: | 16 |
| 2 | The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body. | Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid | 2019 | Genes & Diseases2019,6,3: | 15 |
| 3 | Calcium 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 | 2008 | World Journal of Gastroenterology2008,14,32: | 12 |
| 4 | Neuroimaging the brain-gut axis in patients with irritable bowel syndrome显示文摘AIM:To summarize and synthesize current literature on neuroimaging the brain-gut axis in patients with irritable bowel syndrome(IBS).METHODS:A database search for relevant literature was conducted using Pub Med,Scopus and Embase in February 2015.Date filters were applied from the year2009 and onward,and studies were limited to those written in the English language and those performed upon human subjects.The initial search yielded 797articles,out of which 38 were pulled for full text review and 27 were included for study analysis.Investigations were reviewed to determine study design,methodology and results,and data points were placed in tabular format to facilitate analysis of study findings across disparate investigations.RESULTS:Analysis of study data resulted in the abstraction of four key themes:Neurohormonal differences,anatomic measurements of brain structure and connectivity,differences in functional responsiveness of the brain during rectal distention,and confounding/correlating patient factors.Studies in this review noted alterations of glutamate in the left hippocampus(HIPP),commonalities across IBS subjects in terms of brain oscillation patterns,cortical thickness/gray matter volume differences,and neuroanatomical regions withincreased activation in patients with IBS:Anterio cingulate cortex,mid cingulate cortex,amygdala anterior insula,posterior insula and prefrontal cortex.A striking finding among interventions was the substantia influence that patient variables(e.g.,sex,psychologica and disease related factors)had upon the identification of neuroanatomical differences in structure and con nectivity.CONCLUSION:The field of neuroimaging can provide insight into underlying physiological differences that distinguish patients with IBS from a healthy population. | Kristen R Weaver Lee Anne B Sherwin Brian Walitt Gail D'Eramo Melkus Wendy A Henderson | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,2: | 8 |
| 5 | Dual destructive and protective roles of adaptive immunity in neurodegenerative disorders显示文摘Inappropriate T cell responses in the central nervous system(CNS)affect the pathogenesis of a broad range of neuroinflammatory and neurodegenerative disorders that include,but are not limited to,multiple sclerosis,amyotrophic lateral sclerosis,Alzheimer’s disease and Parkinson’s disease.On the one hand immune responses can exacerbate neurotoxic responses;while on the other hand,they can lead to neuroprotective outcomes.The temporal and spatial mechanisms by which these immune responses occur and are regulated in the setting of active disease have gained significant recent attention.Spatially,immune responses that affect neurodegeneration may occur within or outside the CNS.Migration of antigen-specific CD4+T cells from the periphery to the CNS and consequent immune cell interactions with resident glial cells affect neuroinflammation and neuronal survival.The destructive or protective mechanisms of these interactions are linked to the relative numerical and functional dominance of effector or regulatory T cells.Temporally,immune responses at disease onset or during progression may exhibit a differential balance of immune responses in the periphery and within the CNS.Immune responses with predominate T cell subtypes may differentially manifest migratory,regulatory and effector functions when triggered by endogenous misfolded and aggregated proteins and cell-specific stimuli.The final result is altered glial and neuronal behaviors that influence the disease course.Thus,discovery of neurodestructive and neuroprotective immune mechanisms will permit potential new therapeutic pathways that affect neuronal survival and slow disease progression. | Kristi M Anderson Katherine E Olson Katherine A Estes Ken Flanagan Howard E Gendelman R Lee Mosley | 2014 | Translational Neurodegeneration2014,3,1: | 8 |

| 8 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014,5,2: | 5 |

| 10 | Prognostic impact of the Bismuth-Corlette classification:Higher rates of local unresectability in stageⅢb hilar cholangiocarcinoma显示文摘Background:The Bismuth-Corlette(BC)classification is used to categorize hilar cholangiocarcinoma by proximal extension along the biliary tree.As the right hepatic artery crosses just behind the left bile duct,we hypothesized that BCⅢb tumors would have a higher likelihood of local unresectability due to involvement of the contralateral artery.Methods:A retrospective review of a prospectively maintained database identified patients with hilar cholangiocarcinoma taken to the operating room for intended curative resection between April 2008 and September 2016.Cases were assigned BC stages based on preoperative imaging.Results:Sixty-eight patients were included in the study.All underwent staging laparoscopy after which 16 cases were aborted for metastatic disease.Of the remaining 52 cases,14 cases were explored and aborted for locally advanced disease.Thirty-eight underwent attempt at curative resection.After exclud-ing cases aborted for metastatic disease,the chance of proceeding with resection was 55.6%for BCⅢb staged lesions compared to 80.0%of BCⅢa lesions and to 82.4%for BCⅠ-Ⅲa staged lesions(P<0.05).About 44.4%of BCⅢb lesions were aborted for locally advanced disease versus 17.6%of remaining BC stages.Conclusions:When hilar cholangiocarcinoma is preoperatively staged as BCⅢb,surgeons should antici-pate higher rates of locally unresectable disease,likely involving the right hepatic artery. | Michael J Passeri Maria R Baimas-George Jesse K Sulzer David A Iannitti John B Martinie Erin H Baker Lee M Ocuin Dionisios Vrochides | 2020 | Hepatobiliary & Pancreatic Diseases International2020,19,2: | 3 |

| 14 | Transforming the cost of solar-to-electrical energy conversion: Integrating thin-film GaAs solar cells with non-tracking mini-concentrators显示文摘Practical solar energy solutions must not only reduce the cost of the module,but also address the substantial balance of system costs.Here,we demonstrate a counter-intuitive approach based on gallium arsenide solar cells that can achieve extremely low-cost solar energy conversion with an estimated cost of only 3% that of conventional gallium arsenide solar cells using an accelerated,non-destructive epitaxial lift-off wafer recycling process along with a lightweight,thermoformed plastic,truncated mini-compound parabolic concentrator that avoids the need for active solar tracking.Using solar cell/concentrator assemblies whose orientations are adjusted only a few times per year,the annual energy harvesting is increased by 2.8 times compared with planar solar cells without solar tracking.These results represent a potentially drastic cost reduction in both the module and the balance of system costs compared with heavy,rigid conventional modules and trackers that are subject to wind loading damage and high installation costs. | Kyusang Lee Jaesang Lee Bryan A Mazor Stephen R Forrest | 2015 | Light(Science & Applications)2015,4,1: | 2 |
