The value and significance of nucleolar organizer region proteins as markers of malignancy in breast cancer patients.

Objectives: To assess argyrophilic nucleolar organizer regions (AgNORs) in 60 patients with primary breast carcinoma and evaluated their association with clinical prognostic parameters of breast cancer.

Methods: Argyrophilic nucleolar organizer regions were stained in paraffin sections of the tissues using Ploton's silver method. For each sample, the number of AgNORs within the nuclei of 100 tumor cells was counted.

Syphilis, caused by Treponema pallidum, is resurging globally. Molecular typing allows for the investigation of its epidemiology. In Pakistan and other nations, T.

Epidemiology of Hepatitis B in Saudi Arabia from 2006 to 2021.

Background: This study describes the epidemiological pattern of acute hepatitis B virus (HBV) infection in Saudi Arabia from 2006 to 2021. It explores case frequency and the crude incidence rate (CIR) by year of diagnosis, age group, region, gender, and nationality of patients.

Methods: Retrospective data on acute hepatitis B cases diagnosed across 20 regions of Saudi Arabia during January 2006 to December 2021 were obtained from the Saudi Ministry of Health's Statistical Yearbook.

Epidemiology of gastric cancer in Saudi Arabia from 2004 to 2017.

Gastric cancer (GC), a prevalent disease which globally affects both men and women, was predicted by the International Agency for Research on Cancer in 2020 to have an age-standardized incidence rate (ASIR) in Saudi Arabia of 2.7 per 100,000 individuals for all ages and sexes (ranked 15th), and an age-standardized mortality rate of 2.1 per 100,000 individuals (ranked 12th).

Testicular Cancer in Saudi Arabia Between 2004 and 2017.

Objective: This study examines the epidemiology related to testicular cancer (TC) in the administrative regions of Saudi Arabia by looking at not only the percentage/ frequency of diagnosed cases, but also the crude incidence rate, age-specific incidence rate, and age-standardized incidence rate stratified by the age group, diagnosis year, and regions.

Methods: From 2004 to 2017, descriptive epidemiological research was carried out across all TC cases registered under the Saudi Cancer Registry (SCR). Descriptive statistics as well as the Kruskal-Wallis test, together with SPSS (version 20.

An Approach for Systems-Level Understanding of Prostate Cancer from High-Throughput Data Integration to Pathway Modeling and Simulation.

To understand complex diseases, high-throughput data are generated at large and multiple levels. However, extracting meaningful information from large datasets for comprehensive understanding of cell phenotypes and disease pathophysiology remains a major challenge. Despite tremendous advances in understanding molecular mechanisms of cancer and its progression, current knowledge appears discrete and fragmented.

Streptolysin O concentration and activity is central to in vivo phenotype and disease outcome in Group A Streptococcus infection.

Group A Streptoccocus (GAS) is among the most diverse of all human pathogens, responsible for a range of clinical manifestations, from mild superficial infections such as pharyngitis to serious invasive infections such as necrotising fasciitis and sepsis. The drivers of these different disease phenotypes are not known. The GAS cholesterol-dependent cytolysin, Streptolysin O (SLO), has well established cell and tissue destructive activity.

Epidemiology of Pancreatic Cancer in Saudi Arabia: A Retrospective Analysis of Pancreatic Cancer Diagnosed in Saudi Arabia Between 2004 and 2015.

Purpose: Over the last decades, the incidence of pancreatic cancer has increased, particularly in countries with a higher socioeconomic status. The present work aimed to provide detailed epidemiological data on the incidence of pancreatic cancer in Saudi Arabia.

Patients And Methods: In this retrospective descriptive study, the epidemiological data on pancreatic cancer cases diagnosed in 13 administrative regions of Saudi Arabia between January 2004 and December 2015 were extracted from the Saudi Cancer Registry.

Comparative Study of Gene Expression Profiling Unravels Functions Associated with Pathogenesis of Dengue Infection.

Background: Dengue virus is a potential source of propagating dengue hemorrhagic fever. This virus leads to dengue hemorrhagic fever/dengue shock syndrome, benign syndrome, and severe syndrome and due to its infection, there occurs alterations at multiple levels such as gene expression and pathway levels. So, it is critical to understand the pathogenesis of dengue infection in terms of gene expression and the associated functions.

Epidemiology of Gallbladder Cancer in Saudi Arabia.

Background: Gallbladder cancer is generally rare but can be more common in some populations. The aim of this study was to present an analysis of gallbladder cancer epidemiology in Saudi Arabia.

Materials And Methods: A retrospective study of gallbladder cancer cases in Saudi Arabia from 2004 to 2015 was conducted.

The Incidence Rate of Liver Cancer in Saudi Arabia: An Observational Descriptive Epidemiological Analysis of Data from the Saudi Cancer Registry (2004-2014).

Objective: This study describes the epidemiological pattern of liver cancer in all regions of Saudi Arabia. It explores the frequency of cases diagnosed, the age-specific incidence rate (AIR), the crude incidence rate (CIR), and the age-standardised incidence rate (ASIR) stratified by age group, year of diagnosis, and region.

Methods: A retrospective descriptive epidemiological analysis of all liver cancer cases documented in the Saudi Cancer Registry (SCR) between 2004 and 2014 was performed.

The power of the age standardized incidence rate to discover the gene link between cancer diseases: development of a new epidemiological method to save money, time, and effort for genetic scientists.

Background: This study provides an incipient epidemiological rule using the concept of direct method of standardization to determine the genetic link between cancer diseases.

Methods: The overall 8 or 10 years age standardized incidence rate (ASIR) for both cancer diseases, for example (A) and (B) should be calculated for all regions of the country. A line chart should be used to display the overall ASIR trend of both diseases (A and B).
