Over 4 million infants die each year from infections, many of which are vaccine-preventable. Young infants respond relatively poorly to many infections and vaccines, but the basis of reduced immunity in infants is ill defined. We sought to investigate whether myeloid-derived suppressor cells (MDSC) represent one potential impediment to protective immunity in early life, which may help inform strategies for effective vaccination prior to pathogen exposure.

- The study aimed to identify immune factors in neonates that influence the transmission of HIV-1 from mother to child, comparing infants who got infected to those who did not.
- Researchers analyzed cord blood samples for natural killer (NK) and T-cell populations using advanced techniques and found that infected infants had a unique NK cell profile and less activated immune cells.
- Results suggested that the differences in immune cell types and activation levels in the cord blood could affect the risk of HIV-1 transmission, highlighting the role of both innate and adaptive immunity in this process.
An off-axis Fresnel zone plate, through use of a halftone screen to introduce a spatial carrier frequency, can be used as a large-area, coded aperture for imaging incoherent radiation sources. This paper discusses the structure of off-axis Fresnel zone plate as an aperture and the mentods of imaging from the viewpoint of the spatial resolution by optical simulation, appending some examples of objects, holograms and reconstructed images. It is then concluded that the off-axis Fresnel zone plate having D (diameter) = 5.
