The current reproduction number of COVID-19 in Saudi Arabia: is the disease controlled?

The infectiousness of COVID-19 is high among the susceptible population, making the calculation of the reproduction number (R) an essential step to implement preventive measures. We aim to estimate COVID-19 transmission to determine if the disease is successfully controlled or extra measured should be adopted to attain this goal. The daily incidence data of COVID-19 in Saudi Arabia from March 2, 2020, to April 4, 2021, were obtained from the continuously updated Saudi Ministry of Health COVID-19 repository.

Correlation between measles immunization coverage and overall morbidity and mortality for COVID-19: an epidemiological study.

We conducted the current analysis to determine the potential role of measles vaccination in the context of the spread of COVID-19. Data were extracted from the World Health Organization's (WHO) Global Health Observatory data repository about the measles immunization coverage estimates and correlated to overall morbidity and mortality for COVID-19 among different countries. Data were statistically analyzed to calculate the Spearman rank correlation coefficient (rho).

Correlation between polio immunization coverage and overall morbidity and mortality for COVID-19: an epidemiological study.

We conducted the current analysis to determine the potential role of polio vaccination in the context of the spread of COVID-19. Data were extracted from the World Health Organization's (WHO) Global Health Observatory data repository regarding the polio immunization coverage estimates and correlated to the overall morbidity and mortality for COVID-19 among different countries. Data were analyzed using R software version 4.

The Growth Inhibitory Potential and Antimetastatic Effect of Camel Urine on Breast Cancer Cells In Vitro and In Vivo.

Although it may sound unpleasant, camel urine has been consumed extensively for years in the Middle East as it is believed to be able to treat a wide range of diseases such as fever, cold, or even cancer. People usually take it by mixing small drops with camel milk or take it directly. The project aims to study the effects of camel urine in inhibiting the growth potential and metastatic ability of 4T1 cancer cell line in vitro and in vivo.

Comparative study of keloid formation in humans and laboratory animals.

Background: Keloids are common lesions arising from sites of a previous trauma, and are distinguishable from scars by the presence of continuous growth over the borders of the original injury. The objective of this article is to improve methods for studying keloids using experimental animal models, which may help to promote wound-healing research and to attain suitable management of keloids.

Material/methods: This study consisted of two parts: animal and tissue culture experiments.
