Objectives: The aim of the current study was to identify the expression of P63 and its relation to odontogenic epithelial cell proliferation, severity of the inflammatory infiltrate and size of radicular cysts (RCs).
Methods: In this retrospective cross-sectional study, 30 cases of paraffin-embedded RCs were randomly selected from the archive. P63 and Ki-67 expression was assessed by immunohistochemistry.
Results: Epithelial P63 expression was absent in four (13.3%), weak in 10 (33.3%), and moderate in 16 (53.3%) cases. In the connective tissue wall of RC, P63 expression was absent in two (6.7%) cases, weak in 24 (80.0%) cases, and moderate in four (13.3%) cases. Ki-67 was found to be weakly expressed in 12 (40.0%) cases, moderately expressed in 13 (43.3%), and strongly expressed in five (16.7%) cases. No correlation was found between Ki-67 expression in odontogenic epithelium and P63 expression in the odontogenic epithelium (rho = 0.110, p = .563) or fibrous capsule (rho = 0.160, p = .399). Nevertheless, we found a positive correlation between Ki-67 expression in the odontogenic epithelium and the size of the RC (rho = 0.450, p = .013). The inflammatory infiltrate was negatively correlated with P63 expression in the odontogenic epithelium (rho = -0.428, p = .018), and with the size of cysts (rho = -0.728, p < .001).
Conclusions: There is a high expression of P63 throughout the odontogenic epithelium and connective tissue capsule of the RC. P63 expression in the odontogenic epithelium is negatively correlated with the degree of the inflammatory infiltrate but not with epithelial cell proliferation or the size of the cyst.

Objectives: Therefore, the objective of this study was to analyze the cytotoxic effect of 23 synthetic chalcones on human acute leukemia (AL) cell lines (Jurkat and K562).
Methods: Cytotoxicity assessment was performed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method.
Clinical impacts of Artocarpus lakoocha agglutinin-binding glycans for prognosis and treatment of cholangiocarcinoma.

Artocarpus lakoocha agglutinin (ALA), which specifically targets the Gal/GalNAc components of complex glycans, was isolated from the seeds of Artocarpus lakoocha. This study is the first to explore the role of ALA in identifying aberrant glycans, designated ALA-binding glycans (ALAG), and its implications in cholangiocarcinoma (CCA). ALA-histochemistry was used to evaluate ALAG expression in liver fluke-induced CCA tissues from hamsters (n = 60).

Cellular prion protein (PRNP) has been implicated in various physiological processes in different cell types, for decades. Little has been known how PRNP functions in multiple, yet related processes within a particular system. In our current study, with the aid of high-throughput RNA-sequencing technique, we have presented an overall transcriptome profile of rat vascular smooth muscle cells (VSMCs) with Prnp knockdown.

Objective: Triple negative breast carcinoma (TNBC) is characterized by the absence of estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 receptor expression. Carbonic anhydrase IX (CA IX) is a tumor-associated cell surface glycoprotein that is involved in adaptation to hypoxia-induced acidosis and plays a role in cancer progression. The aim of this study was to investigate CA IX expression in TNBC and its relationship with treatment effect.
