Article Synopsis
- A study was conducted from September 2022 to April 2023 to evaluate how COVID-19 vaccines affect the risk of infection in children under 5 years old.
- The results showed no significant difference in infection risk between vaccinated and unvaccinated children.
- Although the vaccines are effective in preventing severe illness, they may not prevent the actual infection of the virus in young kids.
Changes in Waveguiding Cone Photoreceptors and Color Vision in Patients With Diabetes Mellitus.
Invest Ophthalmol Vis Sci
December 2024
Purpose: Although it is well known that photoreceptor damage and color vision loss occur in patients with diabetic retinopathy (DR), the relationship between structural and functional changes in diabetes mellitus (DM) remains unclear. Using highly sensitive measures of photoreceptor structure and function, we aim to determine whether early loss of color sensitivity in DM is also accompanied by decreased cone density.
Methods: Monocular data from 26 patients with DM and 25 healthy controls were examined to assess cone photoreceptor metrics, using confocal adaptive optics scanning light ophthalmoscopy, and red/green (RG) and yellow/blue (YB) color vision thresholds, using the Colour Assessment and Diagnosis test.
Article Synopsis
- The study investigates the optical conductivity and magnetotransport properties of top-gated devices made from the topological insulator BiSe, focusing on how different carrier types within the material interact.
- Findings reveal that the topologically protected surfaces are somewhat shielded from gate control due to trivial band-bending states but still show significant mobility changes based on external gate bias.
- The research highlights that the optical conductivity is largely influenced by the topological surface states and is particularly affected by scattering from trivial states, suggesting potential uses in future plasmonic device designs.
Fusarium ear rot (FER) and Gibberella ear rot (GER) caused by Fusarium species are major diseases affecting maize production in Ethiopia. In addition to reducing quality and yield, these fungi can produce mycotoxins that contaminate maize kernels and, thereby, pose health hazards to humans and livestock. A survey was conducted in 10 administrative zones of Ethiopia within the major maize-growing regions of the country to identify the species of Fusarium associated with ear rot.

November 2024
Femoral hernias are at a high risk of strangulation due to their narrow necks. They are an exceptionally rare occurrence in males. In many cases, differentiation between a femoral and inguinal hernia is difficult.
