Vertically stacked van der Waals (vdW) heterostructures not only provide a promising platform in terms of band alignment, but also constitute fertile ground for fundamental science and attract tremendous practical interest towards their use in various device applications. Beyond most two-dimensional (2D) materials, which are intrinsically non-magnetic, CrI is a novel material with magnetism dependent on its vdW-bonded layers, promising potential spintronics applications. However, for particular device applications, a heterostructure is commonly fabricated and it is necessary to examine the effect of the interface or contact atoms on the magnetic properties of the heterostructure.

Background: Glioblastoma (GBM) is an aggressive primary brain tumor with a poor prognosis. The current gold standard for GBM treatment, known as the Stupp protocol, includes maximal safe surgical resection followed by radiotherapy and temozolomide chemotherapy. Despite extending survival modestly, this regimen is associated with significant side effects and limited efficacy, resulting in a median survival (MS) of 15 months and a 5-year survival rate of only 7%.

Article Synopsis
  • Sub-Saharan Africa has the highest chronic hepatitis B virus (HBV) infection rates globally, making national HBV prevalence estimates crucial for Kenya's viral hepatitis program.
  • In a study analyzing data from over 3,000 participants aged 15-64 in the 2018 Kenya Population-based HIV Impact Assessment, the national HBV prevalence was found to be 3.0%, equating to approximately 810,600 infected individuals in this age group.
  • The study revealed significant geographical variations in HBV prevalence, with higher rates in certain regions, among people living with HIV, older individuals, those with no formal education, and in lower economic groups; lack of formal education was notably linked to increased HBV infection risk.

Background: There are limited data from sub-Saharan Africa describing the demographic characteristics, clinical features and outcome of patients admitted to public hospitals with severe acute respiratory infections during the COVID-19 pandemic.

Methods: We conducted a prospective longitudinal hospital-based sentinel surveillance between May 2020 and December 2022 at 16 public hospitals in Kenya. All patients aged above 18 years admitted to adult medical wards in the participating hospitals were included.
