Humoral and Innate Immunological Profile of Paediatric Recipients of Pfizer-BioNTech BNT162b2 mRNA Vaccine.

The Pfizer-BioNTech vaccine was one of the essential tools in curtailing the COVID-19 pandemic. Unlike conventional vaccines, this newly approved mRNA vaccine is taken up by cells, which leads to the synthesis of the specific viral Spike antigen. The vaccine was initially introduced for adults, and the immunological profile of adult recipients is well-characterized.

Alzheimer's-linked axonal changes accompany elevated antidromic action potential failure rate in aged mice.

Alzheimer's disease (AD) affects both grey and white matter (WM), but considerably more is known about the former. Interestingly, WM disruption has been consistently observed and thoroughly described using imaging modalities, particularly MRI which has shown WM functional disconnections between the hippocampus and other brain regions during AD pathogenesis when early neurodegeneration and synapse loss are also evident. Nonetheless, high-resolution structural and functional analyses of WM during AD pathogenesis remain scarce.

The prevalence of pseudoexfoliation syndrome in King Hamad University Hospital.

Purpose: The aim of this study is to determine the prevalence of pseudoexfoliation syndrome in patients with cataracts in King Hamad University Hospital (KHUH) and rates of complication in pseudoexfoliation (PXF) patients postoperatively and 2-year follow-up.

Methods: A retrospective analysis was conducted on medical records of PXF patients who underwent phacoemulsification and extracapsular cataract extraction in KHUH, Bahrain, between August 31, 2016, and December 30, 2018.

Results: From the 458 cases analyzed, there were 17 patients with PXF (3.

Tonsillectomy for this 35-year-old patient?

Is tonsillectomy an appropriate treatment modality for this adult patient's refractory group A β-hemolytic streptococcal pharyngitis, in light of her history of recurrent infections?

Cystic fibrosis and fertility.

Purpose Of Review: As the life expectancy of cystic fibrosis (CF) patients continues to increase, and more patients become adults with a chronic disease, researching the impact of the disorder on male and female infertility has become increasingly important. Studies suggest that the prevalence of CF mutations may be higher than previously thought and that many mutations are yet to be identified.

Recent Findings: Assisted reproductive technologies can help both infertile male and female patients with CF in achieving successful parenthood.

A single administration of human umbilical cord blood T cells produces long-lasting effects in the aging hippocampus.

Neurogenesis occurs throughout life but significantly decreases with age. Human umbilical cord blood mononuclear cells (HUCB MNCs) have been shown to increase the proliferation of neural stem cells (NSCs) in the dentate gyrus (DG) of the hippocampus and the subgranular zone of aging rats (Bachstetter et al., BMC Neurosci 9:22, 2008), but it is unclear which fraction or combination of the HUCB MNCs are responsible for neurogenesis.
