Anti_spike and anti_nucleocapsid IgG responses to SARS-CoV-2 in children of Jordan.

Background: It is proven that children have significantly milder COVID-19 disease compared to adults. Various immunological characteristics influence this age-related difference in protection against COVID-19. Pediatric COVID-19 in Jordan is extremely under reported.

FISH analysis reveals CDKN2A and IFNA14 co-deletion is heterogeneous and is a prominent feature of glioblastoma.

Deletion of CDKN2A occurs in 50% of glioblastomas (GBM), and IFNA locus deletion in 25%. These genes reside closely on chromosome 9. We investigated whether CDKN2A and IFNA were co-deleted within the same heterogeneous tumour and their prognostic implications.

Anti-S and Anti-N Antibody Responses of COVID-19 Vaccine Recipients.

The long-term immunoglobulin responses of COVID-19 vaccinations is important to determine the efficacy of these vaccinations. This study aimed to investigate and compare the long-term immunoglobulin response of COVID-19 vaccination recipients, using anti-S IgG, anti-N IgG, and IgM titer levels. This study included 267 participants, comprising individuals who tested positive for COVID-19 through PCR testing ( = 125), and those who received the Pfizer ( = 133), Sinopharm ( = 112), AstraZeneca ( = 20), or Sputnik ( = 2) vaccines.

COVID-19 Vaccine-Related Arthritis: A Descriptive Study of Case Reports on a Rare Complication.

Large-scale coronavirus disease 2019 (COVID-19) vaccination programs have been rolled out worldwide. Vaccines that are widely used globally include mRNA vaccines, adenoviral vector vaccines, and inactivated whole-virus vaccines. COVID-19 vaccines can lead to varying side effects.

Rare Adverse Events Related to Nivolumab, an Immune Checkpoint Inhibitor: A Case Series.

Immune checkpoint inhibitors are a novel class of immunotherapy drugs that have improved the prognosis of melanoma, renal cell carcinoma, non-small cell lung cancer, urothelial carcinoma, and various other solid tumors. Nivolumab is an immune checkpoint inhibitor that acts by inhibiting programmed death. Its use is associated with significant immune-related adverse events, such as pneumonitis, thyroiditis, hepatitis, pruritus, vitiligo, and diarrhea.

Expression of Senescence and Apoptosis Biomarkers in Synchronous Bilateral Breast Cancer: A Case Report.

Background: Synchronous bilateral breast cancer (SBBC) provides a special condition where two independent breast tumors are exposed to cancer pharmacotherapy within a uniform pharmacokinetic milieu. Both senescence and apoptosis are established responses to therapy; however, they have potentially variable contributions to the overall outcome of treatment, which are yet to be determined.

Methods: In this report, we describe the clinicopathological picture of two SBBC cases that received standard anticancer treatment and assess their expression profile of several molecular hallmarks of senescence and apoptosis.
