1Role of endoscopic ultrasound/SpyScope in diagnosis and treatment of choledocholithiasis in pregnancy显示文摘Cholelithiasis and choledocholithiasis occur frequently in pregnancy and their management can be complicated. Traditional endoscopic retrograde cholangiopancreatography(ERCP)is the first line treatment for choledocholithiasis,but in addition to its baseline risks,fluoroscopy poses an additional radiation risk to the fetus. Endoscopic ultrasound(EUS)is an accurate modality for detecting common bile duct stones,but its role has not been defined in pregnancy.We describe an alternative management strategy to conventional ERCP in a pregnant patient with choledocholithiasis and cholangitis detected using EUS and choledochoscopy.Mohit Girotra Niraj Jani 2010World Journal of Gastroenterology2010,16,28:11
2Microwave assisted synthesis of novel Hantzsch 1,4-dihydropyridines,acridine-1,8-diones and polyhydroquinolines bearing the tetrazolo[1,5-α]quinoline moiety and their antimicrobial activity assess显示文摘Microwave assisted efficient Hantzsch reaction via four-component coupling reactions of tetrazolo[1,5-α]quinoline-4-carbal-dehyde, dimedone/cyclohexane-1,3-dione,ethyl/methyl acetoacetate and ammonium acetate was described as the preparation of tetrazolo[1,5-α]quinoline based 1,4-dihydropyridines,acridine-1,8-diones and polyhydroquinolines.The process presented here is simple,rapid,environmentally welcoming and high yielding.All the derivatives were subjected to an in vitro antimicrobial screening against a representative panel of bacteria and fungi and results worth further investigations.Niraj K.Ladani Divyesh C.Mungra Manish P.Patel Ranjan G.Patel 2011Chinese Chemical Letters2011,22,12:7

4Low hypoxia inducible factor-1α(HIF-1α)expression in testicular germ cell tumors--a major reason for enhanced chemosensitivity?显示文摘The molecular basis for enhanced chemosensitivity of testicular germ cell tumors(GCT)has been an area of great interest,as it could potentially give us therapeutic leads in other resistant malignancies.Thus far,however,the increased sensitivity of GCT has been variously attributed to multiple factors—an inability to detoxify cisplatin,a lack of export pumps,an inability to repair the DNA damage,an intact apoptotic cascade and lack of p53 mutation;but a unifying underlying etiology leading to the aforementioned processes and having a translational implication has so far been elusive.Herein,we offer evidence to support a potential significant role for the previously demonstrated low hypoxia inducible factor-1α(HIF-1α)expression in mediating the general exquisite chemosensitivity of testicular GCT,through the aforementioned processes.This molecular mechanism based hypothesis could have a significant translational implication in platinum refractory GCT as well as other platinum resistant malignancies.niraj shenoy roxana dronca fernando quevedo stephen a boorjian john cheville brian costello manish kohli thomas witzig lance pagliaro 2017Chinese Journal of Cancer Research2017,29,4:4
5Novel synthesis and characterization of CuO nanomaterials:Biological applications显示文摘CuO nanoparticles were synthesized at a relatively low temperature(80 ℃) for 2 h using polyethylene glycol-glycerol mixture which acts as a capping agent.A detailed characterization of the synthesized nanomaterials were performed utilizing X-ray diffraction(XRD),infra-red spectroscopy(IR),thermogravimetric analysis(TGA-DTA),transmission electron microscopy(TEM),photoluminescence(PL) by studying its crystalline phase,vibrational mode,thermal analysis,morphology and photoluminescence properties.The effect of annealing on the as-prepared nanoparticles were studied and compared with their corresponding bulk counterpart.The synthesized nanoparticles have been screened for in vitro cytotoxicity(1C_(50)) studies against the human cervical adenocarcinoma cell line(HeLa) using WITT assay methods.The as-prepared nanoparticle inhibits the proliferation of this HeLa cell.The standard disc diffusion method has been used to study the antibacterial activity of the samples against the human pathogenic bacteria Escherichia coli(MTCC 729),Proteus mirabilis(MTCC 425) and Klebsiella pneumoniae subsp.pneumoniae(MTCC 432).The results have been compared with the positive control antibiotic gentamycin.The synthesized nanoparticles would provide a potential alternative to antibiotics for controlling some of the microorganisms causing urolithiasis.Ayekpam Bimolini Devi Dinesh Singh Moirangthem Narayan Chandra Talukdar M.Damayanti Devi N.Rajen Singh Meitram Niraj Luwang 2014Chinese Chemical Letters2014,25,12:4

10Autoimmune pancreatitis and cholangitis显示文摘Autoimmune pancreatitis(AIP) is part of a systemic fibrosclerotic process characterized by lymphoplasmacytic infiltrate with immunoglobulin G subtype-4(Ig G4) positive cells. It characteristically presents with biliary obstruction due to mass-like swelling of the pancreas. Frequently AIP is accompanied by extra-pancreaticmanifestations including retroperitoneal fibrosis, thyroid disease, and salivary gland involvement. Auto-antibodies, hypergammaglobulemia, and prompt resolution of pancreatic and extrapancreatic findings with steroids signify its autoimmune nature. Refractory cases are responsive to immunomodulators and rituximab. Involvement of the biliary tree, termed IgG 4 associated cholangiopathy, mimics primary sclerosing cholangitis and is challenging to manage. High IgG 4 levels and swelling of the pancreas with a diminutive pancreatic duct are suggestive of autoimmune pancreatitis. Given similarities in presentation but radical differences in management and outcome, differentiation from pancreatic malignancy is of paramount importance. There is controversy regarding the optimal diagnostic criterion and steroid trials to make the diagnosis. Additionally, the retroperitoneal location of the pancreas and requirement for histologic sampling, makes tissue acquisition challenging. Recently, a second type of autoimmune pancreatitis has been recognized with similar clinical presentation and steroid response though different histology, serologic, and extrapancreatic findings.Niraj Jani James Buxbaum 2015World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4:2

14Unique case of oligoastrocytoma with recurrence and grade progression:Exhibiting differential expression of high mobility group-A1 and human telomerase reverse transcriptase显示文摘Mixed gliomas, primarily oligoastrocytomas, account for about 5%-10% of all gliomas. Distinguishing oligoastrocytoma based on histological features alone has limitations in predicting the exact biological behavior, necessitating ancillary markers for greater specificity. In this case report, human telomerase reverse transcriptase(hT ERT) and high mobility group-A1(HMGA1); markers of proliferation and stemness, have been quantitatively analyzed in formalin-fixed paraffin-embedded tissue samples of a 34 years old patient with oligoastrocytoma. Customized florescence-based immunohistochemistry protocol with enhanced sensitivity and specificity is used in the study. The patient presented with a history of generalized seizures and his magnetic resonance imaging scans revealed infiltrative ill-defined mass lesion with calcified foci within the left frontal white matter, suggestive of glioma. He was surgically treated at our center for four consecutive clinical events. Histopathologically, the tumor was identified as oligoastrocytoma-grade Ⅱ followed by two recurrence events and final progression to grade Ⅲ. Overall survival of the patient without adjuvant therapy was more than 9 years. Glial fibrillary acidic protein, p53, Ki-67, nuclear atypia index, pre-operative neutrophillymphocyte ratio, are the other parameters assessed. Findings suggest that hT ERT and HMGA1 are linked to tumor recurrence and progression. Established markers can assist in defining precise histopathological grade in conjuction with conventional markers in clinical setup.Puneet Gandhi Richa Khare Kavita Niraj Nitin Garg Sandeep K Sorte Hanni Gulwani 2016World Journal of Clinical Cases2016,4,9:2
15A CLASS OF ENTIRE DIRICHLET SERIES AS AN FK-SPACE AND A FRECHET SPACE显示文摘In the present paper we consider a class of entire functions represented by Dirichlet series whose coefcients belong to a commutative Banach algebra and prove it to be a complex FK-space and a Frechet space.Niraj KUMAR Garima MANOCHA 2013Acta Mathematica Scientia2013,33,6:2
16Eosinophilic enteritis presenting as a rare cause for ileo-ileal intussusception显示文摘Eosinophilic enteritis,a relatively rare entity,usually involves gastric antrum or proximal small bowel. Our case is rarer in its involvement of the distal small bowel and presents unusually as intussusception. The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed,surgical modality is the treatment of choice. In our case,the patient presented with acute intestinal obstruction due to intussusception and emergency laparotomy with ileoileal anastomosis was done. Histopathology confirmed the diagnosis as eosinophilic enteritis. This case with such a presentation is discussed here.Ashok Yadavrao Kshirsagar Sunil Vitthalrao Jagtap Rajkamal Prabhudayal Kanojiya Yogesh Bhupal Langade Sanjay Laxman Shinde Niraj Shekhar 2007World Journal of Gastroenterology2007,13,47:2
