We evaluated the effects of novel benzimidazolone, 1-ethyl-2-benzimidazolinone (1-EBIO), on Cl- secretion across T84 monolayers. 1-EBIO stimulated a sustained secretory response at half-maximal effective concentration 490 microM. Charybdotoxin (CTX) inhibited 1-EBIO-induced short-circuit current (Isc) with an inhibitory constant (Ki) 3.6 nM, whereas 293B, inhibitor adenosine 3',5'-cyclic monophosphate-activated K+ channels, had no effect induced by 1-EBIO. In contrast, CTX failed to inhibit...

We evaluated the effects of clotrimazole and clofibrate on Ca(2+)- adenosine 3',5'-cyclic monophosphate (cAMP)-mediated Cl- secretion in colonic cell line, T84. used 1-ethyl-2-benzimidazolinone (1-EBIO) to activate Ca(2+)-dependent K+ channel (KCa) these cells induce a sustained secretory current (Isc). Clotrimazole potently inhibited KCa-dependent Isc, with an inhibition constant (Ki) 0.27 +/- 0.02 microM. Clofibrate also 1-EBIO-induced Isc albeit lower affinity (Ki = 6.5 1.2 microM). (10...

This study presents a comprehensive assessment of faunal diversity on the University Rajasthan campus, critical green space in rapidly urbanizing city Jaipur, India. Through systematic observational surveys conducted over year 2024, we identified 109 species across 3 phyla, 5 classes, 29 order and 74 families, with Arthropoda dominating (73.5%), followed by Chordata (24.8%) Annelida (1.8%). The high arthropods, particularly pollinators like bees, underscores their ecological importance...

Introduction: Intraoperative cytology in ovarian tumors involves collecting cell samples from the sample sent during surgery and quickly examining them for diagnostic information. Frozen section provides rapid diagnosis to guide intraoperative patient management. The indications of frozen are identification tissue, evaluation margins lymph nodes metastasis. Aim: To evaluate comparative utility squash smear, scrape smear imprint with tumour. Materials methods: tissue clinico-radiologically...

The mainstay of treatment for ovarian cancer is surgery. To prevent under-treatment and overtreatment to choose the best surgical strategy patients with tumors, intraoperative pathological assessment essential. Frozen sections (FSs) have been historically used evaluation. In 1927, cytology was introduced by Dudgeon Patrick as a new method examination. Diagnosis can be made in minutes making smears from lesion, staining them quickly, analyzing under microscope. Following comprehensive search...

Abstract Context Glioblastoma multiforme (GBM) is a malignant and aggressive primary brain tumor with poor prognosis. This adverse prognosis due to the tumor's tendency for advancement recurrence caused by highly intrusive nature of persisting GBM cells that actively escape from main mass into surrounding normal tissue. On basis biomarker illustration, it can be classified molecular subgroups. Aims (1) To determine expression IDH1, ATRX, p53, Ki67 immunohistochemistry, in cohort GBMs. (2)...

We previously demonstrated that 1-ethyl-2-benzimidazolone (1-EBIO) directly activates basolateral membrane calcium-activated K(+) channels (K(Ca)), thereby stimulating Cl(-) secretion across several epithelia. In our pursuit to identify potent modulators of may be useful overcome the secretory defect in cystic fibrosis (CF), we have identified chlorzoxazone [5-chloro-2(3H)-benzoxazolone], a clinically used centrally acting muscle relaxant, as stimulator epithelial cell types, including T84,...

We evaluated effects of psoralens on Cl- secretion (short-circuit current, I(sc)) across T84 monolayers. Methoxsalen failed to increase I(sc). Several observations suggest that open cystic fibrosis transmembrane conductance regulator channels. 1) After activation the Ca2+-dependent basolateral membrane K+ channel (K(Ca)) by 1-ethyl-2-benzimidazolinone or thapsigargin, methoxsalen (10 microM) further increased 2) When added before carbachol (CCh), potentiated I(sc) response CCh, as predicted,...
