Diagnostic Value and Effective Factors on Transbronchial Lung Biopsy Using Cup and Alligator Forceps.

Background: Lung biopsy through the airways by using a flexible bronchoscope (transbronchial lung biopsy: TBLB) is a suitable method for obtaining tissue specimens. This study aimed at evaluating the factors influencing TBLB results in order to increase the diagnostic power of this method.

Materials And Methods: This was a prospective double blind observational study.

NLRP3 Localizes to the Tubular Epithelium in Human Kidney and Correlates With Outcome in IgA Nephropathy.

Nod-like receptor pyrin domain-containing-3 (NLRP3) has been implicated in the pathogenesis of experimental renal injury, yet its characterization in human kidney disease remains largely unexplored. NLRP3 expression was evaluated in human kidney biopsies, primary renal tubular cells (HPTC) and correlated to disease outcomes in patients with IgA nephropathy (IgAN). NLRP3 localized to renal tubules in normal human kidney tissue and to mitochondria within HPTC by immunohistochemistry and immunofluorescence microscopy.

Effects of propofol versus isoflurane on liver function after open thoracotomy.

Background: Anesthetic agents and type of surgery may contribute to postoperative hepatic injury. Inhalational anesthetics have been associated with hepatic dysfunction after surgery, however, propofol is expected to have a lower potential for postoperative liver injury. This prospective double-blind randomized clinical study was planned to determine whether postoperative liver function differs after anesthesia with isoflurane and total intravenous anesthesia with propofol in patients undergoing a posterolateral thoracotomy.

Inhibition of hTERT Gene Expression by Silibinin-Loaded PLGA-PEG-Fe3O4 in T47D Breast Cancer Cell Line.

Introduction : Nowadays, using drug delivery is an essential method to improve cancer therapy through decreasing drug toxicity and increasing efficiency of treatment. Silibinin (C25H22O10), a polyphenolic flavonoid which is isolated from the milk thistle plant, has various applications in cancer therapy but it has hydrophobic structure with low water solubility and bioavailability. To increase the effect of silibinin, silibinin-loaded PLGA-PEG-Fe3O4 was prepared to determine the inhibitory effect of this nanodrug on Telomerase gene expression.

No association between simian virus 40 and diffuse malignant mesothelioma of the pleura in Iranian patients: a molecular and epidemiologic case-control study of 60 patients.

Background: Diffuse malignant mesothelioma (DMM) is increasing in incidence on a worldwide basis and is linked to exposure to asbestos. Simian virus 40 (SV40), a DNA virus, was introduced inadvertently to human populations through contaminated polio vaccine during the years 1956-1963. It has been associated with various types of malignancy in animal experiments.

Incidence of fever and bacteriemia following flexible fiberoptic bronchoscopy: a prospective study.

The latest American Heart Association (AHA) statement for preventing infectious endocarditis, has not recommended prophylactic antibiotic therapy prior to fiberoptic bronchoscopy (FB) except for patients with preexisting predisposing cardiac conditions. Our aim was to determine the incidence of bacteriemia and fever following FB in our experience and compare with those which have been mentioned in AHA guideline as well as other studies. Venous blood of 85 consecutive patients was evaluated for both aerobic and anaerobic cultures before (for detecting possible previous bacteriemia) and after FB.

Clonality of the immunoglobulin heavy chain genes in B cell non-hodgkin lymphoma using semi-nested PCR.

Background: Identification of gene rearrangements and clonality analysis are important techniques for the diagnosis of malignant lymphoproliferative diseases. These methods have various sensitivities based on the type of primer used and method of determination of polymerase chain reaction (PCR) products. This study aimed at determining the clonality of B cell non-Hodgkin lymphoma in Iranian patients using PCR method and 2 primers of FR2 and FR3.

Primary pulmonary plasmacytoma with diffuse alveolar consolidation: a case report.

Solitary extramedullary plasmacytomas are plasma cell tumors that tend to develop in mucosa-associated lymphoid tissues including the sinonasal or nasopharyngeal regions. Primary plasmacytoma of the lung is exceedingly rare and often presents as a solitary mass or nodule in mid-lung or hilar areas and diagnosed after resection. Herein, we report a case of primary pulmonary plasmacytoma that presented with diffuse alveolar consolidation and diagnosed by transbronchial lung biopsy.

The diagnostic value of Ki-67 and repp86 in distinguishing between benign and malignant mesothelial proliferations.

Context: The differentiation of benign mesothelial proliferations from malignant mesotheliomas may be difficult, especially when evaluating small specimens from pleural biopsies.

Objective: To explore the potential value of 2 proliferative cell markers, Ki-67 and restrictedly expressed proliferation-associated protein 86 kDa (repp86), in distinguishing between malignant mesothelioma (MM) and benign reactive mesothelial hyperplasia (MH).

Design: Thirty-six cases of MM from 26 men and 10 women with a mean age of 62.

Prognostic values of proliferative markers ki-67 and repp86 in breast cancer.

Background: Breast cancer is the leading cause of carcinoma death in women. Proper treatment depends on the consideration of molecular biology status of tumor cells, which may determine the patient's treatment and prognosis. To determine the prognostic models for this disease, we evaluated the role of cell proliferation-related antigens including ki-67 (a nuclear antigen, expressed in G1, G2, and M phases of cell cycle) and repp86 (an 86-kDa nuclear protein expressed in S, G2, and M phases of cell cycle) for detection of biologic behavior of breast cancer.
