Invasive Pulmonary Aspergillosis In Solid-Organ Transplant Recipients: Postmortem Histopathologic Findings, Banu Bi̇lezi̇kçi̇, Beyhan Demi̇rhan, Asuman Ni̇han Haberal, Ünser Arikan

Turkish Journal of Medical Sciences

Invasive aspergillosis is often lethal in transplant recipients. The mortality associated with this disease after organ transplantation approaches 100%, partly because it is difficult to recognize and diagnose early on. The clinical course and histological findings in invasive pulmonary aspergillosis in immunocompromised hosts differ from those seen in patients who develop classic aspergillomas. In immunosuppressed patients, the predominant pathologic abnormalities are tissue invasion, abscess formation, and angioinvasion with or without infarction. In this study, we examined cases of invasive pulmonary aspergillosis in one kidney recipient and three liver transplant recipients. All the patients were male, and their mean age was …

Discrimination Between The Acidic And Molecular Effects Of Lactate On Muscle Tension Development, Şeref Erdoğan, Sanli Sadi̇ Kurdak, Ni̇lay Ergen, Ayşe Doğan Jan 2002

Discrimination Between The Acidic And Molecular Effects Of Lactate On Muscle Tension Development, Şeref Erdoğan, Sanli Sadi̇ Kurdak, Ni̇lay Ergen, Ayşe Doğan

Turkish Journal of Medical Sciences

Fatigue can be defined as the decrease in the genesis of maximal muscle tension, and it may develop when metabolic end-products cannot be readily washed out. During anaerobic exercises, lactate accumulates in the muscle and blood, resulting in acidic pH in these tissues. Fatigue during lactate accumulation is generally attributed to its acidifying property; however, the inverse effect of lactate on muscle tension also at isopH values may be due to the molecular as well as the acidifying effects of this metabolite. In this study, we aimed to distinguish the molecular and acidifying effects of high lactate, both of which …

Antitumor Effects Of Tnf-\Beta, 5-Fu And Their Combinations On Cervical Carcinoma Cell Lines, Hakan Akça, Osman Ni̇dai̇ Özeş Jan 2002

Antitumor Effects Of Tnf-\Beta, 5-Fu And Their Combinations On Cervical Carcinoma Cell Lines, Hakan Akça, Osman Ni̇dai̇ Özeş

Turkish Journal of Medical Sciences

Cervical carcinoma is one type of cancer with a high mortality rate in females. In this study, we investigated the cytotoxic effects of TNF-\beta, 5-FU and their combinations on human cervical carcinoma cell lines, ME180 and HeLa. The highest degree of cytotoxic effect was obtained with 5-FU on both cell lines. While high concentrations of TNF-\beta showed cytotoxic effects on both cell lines, the lowest dose induced growth. Combination treatment of 5-FU and TNF-\beta gave a slightly higher cytotoxic and antiproliferative response compared to individual use of 5-FU and TNF-\beta on both cell lines.

Genetic Polymorphisms In Steroid Hormone Metabolizing Enzymes In Human Breast Cancer, Nesli̇han Aygün Kocabaş Jan 2002

Genetic Polymorphisms In Steroid Hormone Metabolizing Enzymes In Human Breast Cancer, Nesli̇han Aygün Kocabaş

Turkish Journal of Medical Sciences

Epidemiologic studies indicate that most risk factors for breast cancer are related to reproductive and hormonal factors. The evaluation of associations between breast cancer risk and genetic polymorphisms in enzymes involved in hormone metabolism may be a cost effective manner in which to determine individual breast cancer susceptibility. A number of molecular epidemiologic studies have been conducted to evaluate associations between polymorphic genes involved in steroid hormone metabolism (i.e., CYP17, CYP19, CYP1A1, CYP1B1, MnSOD, COMT, and GST) that may account for a proportion of enzymatic variability. An evaluation of associations between breast cancer risk and genetic polymorphisms in enzymes involved …
