BACKGROUND: Metallothionein (MT) protein expression deficiency has been implicated in carcinogenesis while MT over expression in tumors is indicative of tumor resistance to anti-cancer treatment. The purpose of the study was to examine the expression of MT expression in human renal cell carcinoma (RCC) and to correlate MT positivity, the pattern and extent of MT expression with tumor histologic...

The t(11;18)(q21;q21) translocation is a specific marker for Helicobacter pylori-independent status of low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, there are no reliable markers to predict tumor response to H pylori eradication in patients without t(11;18)(q21;q21). Nuclear expression of BCL10 and nuclear factor kappa B (NF-kappaB) was recently found to be close...

Background: Intracytoplasmic sperm injection (ICSI) can be considered the solstice in vitro insemination technique because it has powerfully allowed the treatment of male factor infertility, but in this procedure, except visual morphological selection, there is no standardization for sperm selection. Recently, hypo osmotic swelling test (HOST) has been proposed to have the potential to select i...

Background and Objective: Histological grading has prognostic and therapeutic implications in meningioma. However, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. P63 gene is a novel P53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. In this study,...

BACKGROUND Clinical and histopathologic characteristics that may predict risks of recurrence in women with ductal carcinoma in situ (DCIS) have not been consistently identified. We identified factors associated with recurrence as DCIS versus invasive breast cancer and determined the 5-year absolute risks of recurrence as a function of these factors. METHODS We conducted a population-based coh...

i.p.s. hypergroups are canonical hypergroups such that$[forall(a,x),a+xni x]longrightarrow[a+x=x].$i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved thatif the order is less than 9, they are strongly canonical (see [13]). in this paperwe obtain the sequences of fuzzy sets and of join spaces determined (see [8])by all i.p.s. hypergroups of order seven. for the meaning ...

CONTEXT Among the cytological and morphological properties of mucoepidermoid carcinoma, one of the most important criteria for measuring its biological behavior and aggressiveness is cell proliferation. In this way, immunohistochemical markers of cell proliferation have been found to be useful in tumor classification and have formed part of the prognostic and therapeutic studies of these pathol...

Estimating the size of India’s inventory of separated weapon-grade plutonium has become more difficult following its nuclear tests in May 1998. India treats this number as highly classified, partly because such estimates provide a direct indication of the number of nuclear weapons it may possess. The purpose of this report is to summarize estimates of its stock of weapon-grade plutonium. A comp...
