1Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis.Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak 2015World Journal of Gastroenterology2015,21,12:14
2Immunoexpression of cyclooxygenase-2 in primary gastric carcinomas and lymph node metastases显示文摘AIM: To evaluate immunoexpression of cyclooxygenase-2 (COX-2) in primary gastric carcinomas and respective lymph node metastases. METHODS: Immunohistochemistry to analyze COX-2 expression was performed on tissue microarray slices obtained from 36 specimens of gastrectomy and satellite lymph nodes from patients with gastric carcinoma. RESULTS: Immunostaining was seen in most cases, and COX-2 expression was higher in lymph node me-tastases than in corresponding primary gastric tumors of intestinal, diffuse and mixed carcinomas, with a statistically signif icant difference in the diffuse histotype (P = 0.0108). CONCLUSION: COX-2 immunoexpression occurs frequently in primary gastric carcinomas, but higher expression of this enzyme is observed in lymph node metastases of the diffuse histotype.Paulo RC Almeida Francisco VA Ferreira Cássio C Santos Francisco D Rocha-Filho Raul RP Feitosa Esther AA Falco Belise K Cavada Roberto CP Lima-Júnior Ronaldo A Ribeiro 2012World Journal of Gastroenterology2012,18,8:14
3Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
4Molecular approaches for spinal cord injury treatment显示文摘Injuries to the spinal cord result in permanent disabilities that limit daily life activities.The main reasons for these poor outcomes are the limited regenerative capacity of central neurons and the inhibitory milieu that is established upon traumatic injuries.Despite decades of research,there is still no efficient treatment for spinal cord injury.Many strategies are tested in preclinical studies that focus on ameliorating the functional outcomes after spinal cord injury.Among these,molecular compounds are currently being used for neurological recovery,with promising results.These molecules target the axon collapsed growth cone,the inhibitory microenvironment,the survival of neurons and glial cells,and the re-establishment of lost connections.In this review we focused on molecules that are being used,either in preclinical or clinical studies,to treat spinal cord injuries,such as drugs,growth and neurotrophic factors,enzymes,and purines.The mechanisms of action of these molecules are discussed,considering traumatic spinal cord injury in rodents and humans.Fernanda Martins de Almeida Suelen Adriani Marques Anne Caroline Rodrigues dos Santos Caio Andrade Prins Fellipe Soares dos Santos Cardoso Luiza dos Santos Heringer Henrique Rocha Mendonça Ana Maria Blanco Martinez 2023Neural Regeneration Research2023,18,1:3
