Expression of Ki-67 in Invasive Breast Carcinoma and Its Correlation With Different Clinicopathological Features.

Introduction Worldwide, breast cancer is still the most common cancer that affects women. Breast cancer prognosis is based on a number of clinical and pathological indicators. Further features are needed to predict early metastasis and prognosis of patients with breast carcinoma, as the current pathological characteristics, such as tumor differentiation, vascular infiltration, and TNM (tumor, node, and metastasis) staging, cannot fully describe the early metastatic biological behavior in breast carcinoma.

Immunohistochemical Expression of Cyclooxygenase 2 (COX-2) as a Prognostic Marker and Its Correlation With Clinicopathological Parameters in Breast Cancer.

Introduction Breast cancer is considered the most common cancer among women. According to the literature, cyclooxygenase-2 (COX-2) expression in breast carcinoma is associated with aggressive tumor biology and acts as an independent prognostic marker. As COX-2 is a newly identified marker, studies are required to understand its immunoexpression and correlation with hormone receptor status and other prognostic factors, which helps in the therapeutic management of patients.

A cross sectional analysis of medical device associated adverse events with radiotherapy devices - A materiovigilance study.

Background: Materiovigilance is a method for tracking, documenting, and analyzing the causal factors of adverse outcomes or complications associated with the use of medical devices. In addition, it recommends that the Indian regulatory authority takes necessary steps with the aim of enhancing patient safety. The present study was taken up as there are hardly any studies available in the public domain on adverse events due to radiotherapy.

Packing polymorphism, odd-even alternation and thermotropic phase transitions in -,-diacylethanolamines with varying -acyl chains. A combined experimental and computational study.

-,-Diacylethanolamines (DAEs) are derived by simple esterification of bioactive -acylethanolamines, which are present in plant and animal tissues. In this study, two homologous series of DAEs, namely -acyl ( = 8-15), -palmitoylethanolamines (N-O16s) and -acyl ( = 8-14), -pentadecanoylethanolamines (N-O15s) were synthesized and characterized with respect to thermotropic phase transitions, crystal structures and intermolecular interactions. In addition, computational studies were performed to get a molecular level insight into the role of different factors in selective polymorphism in N-O16s and N-O15s.
