Background: The RBCs storage lesion is most carefully viewed as the sum of all the changes in RBCs occurring during the course of storage and that limit their survival.
Materials And Methods: Erythrocytes were isolated from stored blood at regular intervals. Oxidative stress markers were analyzed to determine the changes during the storage.
Results: Antioxidant enzymes--(SOD and CAT), and SH showed insignificant variation whereas hemolysis, MDA and AOPP showed significant variations.
Conclusion: The oxidative stress has not successfully overridden the protection offered by the endogenous antioxidant system. Prolonged storage may result in the onset of erythrocyte deterioration. This clearly indicates that the erythrocytes are capable of attenuating ROS with 2 weeks of storage.

Background: Studies of pediatric osteoarticular infections (OAIs) mostly focus on acute hematogenous osteomyelitis (AHO) and acute bacterial arthritis (ABA). A comprehensive descriptive analysis of pediatric OAIs, including subacute, chronic, and non-hematogenous types, is lacking.
Methods: A detailed analysis of all pediatric OAIs was undertaken at two academic centers, Hasbro Children's Hospital, Providence, RI, and Nationwide Children's Hospital, Columbus, OH.
Background And Aims: People who have diabetes mellitus (DM) are thought to be more susceptible to pulmonary tuberculosis (PTB). Several published comparative investigations have reported that chest x-ray images from PTB with DM are considered atypical due to their frequent involvement of the lower lung field (LLF). This study aimed to investigate the frequency of lower lung field tuberculosis (LLF-TB) in DM and the risk factor of DM for the development of TB.

Background: A number of immunotherapeutic approaches have been developed and are entering the clinic. Bispecific antibodies (BsAbs) are one of these modalities and induce robust efficacy by endogenous T cells in several hematological malignancies. However, most of the treated patients experience only a temporary benefit.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has highlighted the urgent need for novel therapeutic agents targeting viral enzymes such as the main protease (Mpro), which plays a crucial role in viral replication. In this study, we investigate the inhibitory potential of 23 peptides isolated from the skin of amphibians belonging to the Hylidae and Leptodactylidae families against SARS-CoV-2 Mpro. Five peptides demonstrated significant inhibition using a colorimetric Mpro inhibition assay, with IC50 values ranging from 41 to 203 µM.
