Influenza virus infections continually pose a major public health threat with seasonal epidemics and sporadic pandemics worldwide. While currently licensed influenza vaccines provide only strain-specific protection, antigenic drift and shift occasionally render the viruses resistant to the host immune responses, which highlight the need for a vaccine that provides broad protection against multi...
This paper examines the hypothesis that non-US firms cross-list in the United States to increase protection of their minority shareholders. Cross-listing on the NYSE or Nasdaq subjects a non-US firm to a number of provisions of US securities law, and requires the firm to conform to US GAAP. It therefore increases the expected cost to managers of extracting private benefits, and commits the firm...
During the global COVID-19 pandemic, the rate of mortality and morbidity was fairly low in Pakistan compared to western countries. Bacille Calmette-Guerin (BCG) vaccination provides cross-protection for a broad range of related and unrelated pathogens. This protection is attributed to the recognition of broadly cross-reactive Pathogen-Associated Molecular Pattern (PAMPS) like molecules. We inve...
Class I major histocompatibility complex-restricted parasite-specific cytotoxic T lymphocytes (CTL) are known to be a major component of the bovine immune response to the protozoan parasite Theileria parva, but formal proof for their role in protection of cattle against infection with T. parva has been lacking. Animals immunized with one stock of T. parva show variations in the degree of protec...
Background and aims: Employees in hospitals and healthcare centers are exposed to a wide range of respiratory contaminants, such as biological and chemical contaminants. To protect employees against these hazards, it is necessary to use respiratory masks with appropriate protection factor. This study aimed to assess respiratory hazards risk to determine the protection factor of mask in one of t...
