RESUMO

We identified two genes related to fungicide resistance in Fusarium fujikuroi through random mutagenesis. Targeted gene deletions showed that survival factor 1 deletion resulted in higher sensitivity to fungicides, while deletion of the gene encoding F-box/WD-repeat protein increased resistance, suggesting that the genes affect fungicide resistance in different ways.

RESUMO

PURPOSE: Although advancement in treatment and diagnostic tools related to hepatocelluar carcinoma has been much improved, long term survival rates of hepatocellular carcinoma are still low because of delayed clinical manifestations and underlying diseases causing the cancer. Various kinds of modalities to treat hepatocellular carcinoma have developed but surgical resection is still recognized as the best method. Therefore, we studied the associated factors of long-term survival after liver resection. METHODS: We retrospectively analyzed 184 patients who were pathologically diagnosed with hepatocellular carcinoma from May 1990 to December 2002. Associated factors of long-term survival classified as preoperative, operative, pathological and recurrence factors. Univariate and multivariate analyses were done using cross tabulation analysis and logistic regression analysis. RESULTS: The cumulative 1-, 3- and 5- year survival rates were 66%, 50% and 30%, respectively. Preoperative factors, significantly associated with long-term survival, were age of 60 years and under, tumor size, HBe Ag status and preoperative tumor marker level. As pathological factors, the vascular invasion and lymphatic invasion status were significantly associated. But cirrhosis of the liver was not associated with long-term survival. And in cases of recurrence, patients who had undergone repeat resection survived significantly longer. CONCLUSION: The most significant factors of multivariate analyses were lymphatic invasion status. Tumor size, ICG-R15 and HBe Ag status followed second. We should correct the preoperative factors through screening and early diagnosis. And when recurrence occurs, if the recurring cancer has resectability, repeat hepatectomy will increase the patient's lifespan.

RESUMO

@#ObjectiveTo explore the early factors influencing 30 days survival of hypertensive intracerebral hemorrhage.MethodsThe data of 96 cases of hypertensive intracerebral hemorrhage were analyzed with log-rank and cox model.ResultsGCS scores, systolic blood pressure (SBP), diastolic blood pressure (DBP), body temperature, FPG, the volume of hemorrhage whether or not breaking through ventricle were significant factors in log-rank and GCS scores, body temperature, FPG, the volume of hemorrhage showed a significant relation in cox model.ConclusionMany factors can induce the death of hypertensive intracerebral hemorrhage patients; the most important factors are coma, body temperature, FPG, the volume of hemorrhage.

RESUMO

PURPOSE: Insulin-like growth factor-I (IGF-I) is an important mitogen in many types of malignancies. The purpose of this study was to evaluate the role of the IGF system on cell proliferation and cell death in mouse lung cancer cell lines (3LL). MATERIALS AND METHODS: Northern analysis was performed in 3LL cells. We evaluated the phosphorylation of IGF-I receptor (IGF-IR) with IGF-I stimulation. MTT assay was performed after treating 3LL cells with IGF-I and the treatment effect on cell death in the presence of anticancer drug was investigated. RESULTS: Northern analysis revealed the presence of IGF-I and IGF-IR mRNA expression in 3LL cells. IGF-I increased cellular proliferation in serum free media. IGF-I also stimulated the tyrosine phosphorylation of two proteins: one, with a molecular mass of 95 kDa, was the beta-subunit of IGF-IR; the other, with an approximate molecular mass of 185 kDa, was originally identified as the insulin receptor substrate-I (IRS-I). IGF-I at a low concentration inhibited the cell death induced by adriamycin. CONCLUSION: IGF-I, a mitogen through the phosphorylation of the IGF-IR beta-subunit, acts as a survival factor to inhibit cell death. Therefore, these findings suggest that IGF-I and IGF-IR are involved in both the cell proliferation and cell death associated with cancer cell growth.
