Recently, we developed and optimized a new method for the evaluation of the protective properties of serotype 2 inactivated poliovirus vaccines (IPV). The method is based on the immunization and subsequent challenge of transgenic (Tg) mice susceptible to poliovirus. We describe a similar method for the assessment of the protectiveness of serotype 1 IPV and demonstrate that experimental IPV produced from attenuated Sabin strain (sIPV) of serotype 1 poliovirus induced serum neutralizing antibodies, immunoglobulin (Ig) G, IgM, and salivary IgA at titers comparable to those induced by conventional IPV (cIPV) produced from the wild-type Mahoney strain. In contrast to our previous results with serotype 2 sIPV, serotype 1 sIPV provided even better protection of Tg mice than cIPV against challenge with wild-type Mahoney strain.

Background: High-density lipoprotein (HDL) function, rather than its concentration, plays a crucial role in the development of coronary artery disease (CAD). Diminished HDL antioxidant properties, indicated by elevated oxidized HDL (nHDL) and diminished paraoxonase-1 (PON-1) activity, may contribute to vascular dysfunction and inflammation. Data on these associations in CAD patients, including acute coronary syndrome (ACS), remain limited.

Root-knot nematodes (RKNs), particularly , are one of the most destructive plant-parasitic nematodes (PPNs) affecting crop production worldwide. Previous earlier study revealed that calcinated oyster shell powder (OSP) possessed excellent suppression of tobacco RKN disease. However, the suppression mechanism of OSP against RKNs still remains unrevealed.

Medical interventions, such as masks, were a cornerstone in mitigating the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since 2019, the scientific community has increasingly focused on exploring avenues for pandemic prevention and preparedness to enhance responses to future viral outbreaks. One such area of interest explores the use of additives, such as silicon nitride (Si₃N₄), in masks to enhance the antiviral properties of personal protective equipment.

Background: Male infertility is a global health issue, with pharmaceutical agents such as cimetidine contributing significantly to gonadotoxicity through antiandrogenic and oxidative mechanisms. The search for natural protective agents has highlighted var. (collard greens) for its antioxidant and endocrine-modulating properties.

Background: Serum and other blood-derived products are widely used in biomedical and biopharmaceutical processes, especially for the production of vaccines or cell therapeutic applications. To ensure quality and safety, each serum lot undergoes testing for sterility to minimize the risk of disease transmission. A currently performed standard procedure is gamma-irradiation of serum for effectively killing pathogens.
