Prevalence and Outcomes of Emergency Presentations of Colorectal Cancer in Veterans Affairs Health Care System.

Background: Colorectal cancer (CRC) diagnoses are frequently made through emergency presentations (EPs), a new cancer diagnosis following an emergency care episode or unplanned inpatient admission. The extent and implications of EPs are not well known in the Veterans Affairs (VA) health system, where robust CRC screening protocols exist. The impact of the COVID-19 pandemic on the route of CRC diagnosis also remains unclear.

A novel approach to designing viral precision vaccines applied to SARS-CoV-2.

Efficient precision vaccines against several highly pathogenic zoonotic viruses are currently lacking. Proteolytic activation is instrumental for a number of these viruses to gain host-cell entry and develop infectivity. For SARS-CoV-2, this process is enhanced by the insertion of a furin cleavage site at the junction of the spike protein S1/S2 subunits upstream of the metalloprotease TMPRSS2 common proteolytic site.

Physical properties and mass models of Deglet Noor and Arichti semi-dry Algerian date fruits: A comparative study.

For thousands of years, date fruit ( L.) has been a popular diet in arid and semi-arid locations. It has religious importance for Muslims and is especially important during the holy month of Ramadan.

Molecular identification and antifungal susceptibility profiles of etiologic agents of oral candidiasis among HIV-positive patients: A multicenter study.

Background And Purpose: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a serious risk factor for oral candidiasis (OC). In this regard, the present study aimed to investigate the frequency of species collected from the oropharyngeal cavity of HIV-positive patients and the sensitivity of these isolates to antifungal drugs.

Materials And Methods: Oral samples were collected from 169 HIV-positive patients.
