BACKGROUND The study aimed to investigate the utility of dynamic contrast enhanced MRI (DCE-MRI) in the differentiation of malignant, borderline, and benign complex ovarian tumors. METHODS DCE-MRI data of 102 consecutive complex ovarian tumors (benign 15, borderline 16, and malignant 71), confirmed by surgery and histopathology, were analyzed retrospectively. The patterns (I, II, and III) of ...

The concepts of cumulative distribution function and empirical distribution function are investigated for fuzzy random variables. Some limit theorems related to such functions are established. As an application of the obtained results, a method of handling fuzziness upon the usual method of Kolmogorov–Smirnov one-sample test is proposed. We transact the α-level set of imprecise observations in ...

Human T cell clones and a cDNA probe specific for constant regions of the beta subunit of the antigen/major histocompatibility complex (MHC) receptor, TiC beta 1 and TiC beta 2, were employed to determine whether these genes were differentially used by functional classes of T lymphocytes. DNA from 10 interleukin-2-dependent T cell clones including class I and class II MHC-specific cytotoxic T l...

During ovarian follicle growth, precise regulation of the onset of androgen production by ovarian theca-interstitial cells (TIC) is necessary for maintaining follicle viability. Thus, temporary suppression of TIC androgen production in preantral follicles is the key to promoting follicle development. Evidence indicates that this process is coordinated via intraovarian growth factors. Hepatocyte...

The delta opioid receptor modulates nociceptive and emotional behaviors. This receptor has been shown to exhibit measurable spontaneous activity. Progress in understanding the biological relevance of this activity has been slow, partly due to limited characterization of compounds with intrinsic negative activity. Here, we have used constitutively active mutant (CAM) delta receptors in two diffe...

OBJECTIVE To explore if self-reported presence of thinking about tics or body-focused repetitive behaviours (BFRBs; gests) are direct triggers of tic or gest onset in 3 groups: Tourette syndrome (TS; n =18), persistent chronic tic disorders (TDs; n = 42), and a comparison group with BFRB (n = 36). METHOD The 3 groups completed a thinking about tics inventory, listing 22 items derived from cli...

the gene coding claudin (cldn5) is located on 22q11. since the proteins of cldn5 family are a ma-jor component for barrier-forming tight junctions, it may be important to test whether or not the cldn5 locus could be associated with schizophrenia.a total of 150 individuals affected with schizophrenia and 150 healthy persons were recruited. the relation-ship between the three single nucleotide po...
