Ligation of B cell receptors on immature bone marrow B cells, either by an endogenous Ag or by an anti-B cell receptor Ab induces secondary V(D)J gene rearrangements, termed receptor editing. Whether the same signal induces receptor editing in transitional B cells is not clear. In this study, we examined the responses of immature and transitional B cells from V(H)12Vkappa1A Ig transgenic mice t...

Follicle growth and associated changes in circulating hormone concentrations were evaluated after follicle ablation in mares (n = 13) during four 13 day periods beginning at means of -98.5, -61.4, -26.0 and 10 days from the first ovulation and corresponding to mid-anovulatory, early-transitional, late-transitional and ovulatory periods, respectively. During each period, all follicles > 5 mm in ...

INTRODUCTION The aim of this study was to evaluate the levels of p53 protein in serum and urine samples of patients with bladder transitional cell carcinoma (TCC) and their relation with the overexpression of p53 in the tumoral tissue. MATERIALS AND METHODS A total of 39 patients with bladder TCC were evaluated for p53 protein in their serum and urine samples and the overexpression of this ma...

Transitions are the glue that holds a paper together. These cohesive allies are needed when a paper “does not flow,” is “choppy,” or seems unrelated to the thesis of their parent essay. Transitions can be simple, such as the following: moreover, therefore, nevertheless, despite, consequently, instead, also. However (that’s another transition), it is better to use transitional phrases, rather th...

A serum-free medium, DH-S1, is described which is valuable for the establishment of primary cultures of normal and malignant transitional epithelium (transitional cell carcinoma of the bladder). Growth of epithelial cells in DH-S1 is facilitated but that of fibroblasts is suppressed. Another established human transitional cell carcinoma cell line, 647V, has grown continually in DH-S1 for over 3...

Biplane left ventricular angiography was performed in 22 patients with isolated obstructive disease of the anterior descending branch of the left coronary artery and with an anterior aneurysm following transmural myocardial infarction. Six patients were restudied between 6 and 10 months after aneurysmectomy. Left ventricular reserve was estimated by analysis of a spontaneous postextrasystolic b...

Transitional spaces have been widely applied in building designs nowadays, which are present in the form of atria, lobbies, corridors and covered streets. As they have become common features of buildings, they account for 1040% of the total volume in different types of buildings. However, maintaining an acceptable thermal comfort for transitional spaces poses challenges to building designers an...

Phosphotungstic acid at low pH and colloidal iron hydroxide have been used to stain sialic acid residues at the surfaces of the transitional epithelium that covers the human urinary bladder. The staining of surfaces of normal epithelium was compared in the electron microscope to staining of surfaces of cells from noninvasive Grade I transitional cell carcinomas and from higher grades of invasiv...

Transitional justice has typically relied on a handful of mechanisms, including trials, truth commissions, and reparations programmes, in seeking justice after conflict. In many societies, however, these mechanisms have less salience and value than do traditional practices of justice. Often, this occurs in large part because these transitional justice mechanisms have been imported and the commu...

In a longitudinal study, five indicators of a transition in the development of analogical reasoning were examined in young elementary school children, (a) bimodality and (b) inaccessibility in the frequency distributions of test performance, and in the responses of the transitional subjects, respectively, (c) sudden jumps, (d) anomalous variance, and (e) critical slowing down. An open-ended geo...
