Children suffering from severe acute malnutrition (SAM) have a weakened immune system. The relationship between malnutrition and alterations in the frequency of peripheral blood mononuclear cells (PBMCs) remains unclear. This study investigated the altered immune responses in Bangladeshi children with SAM compared to healthy children.

The diffuse Galactic gamma-ray emission is a very important tool used to study the propagation and interaction of cosmic rays in the Milky Way. In this Letter, we report the measurements of the diffuse emission from the Galactic plane-covering Galactic longitudes from 15° to 235° and latitudes from -5° to +5°, in an energy range of 1 to 25 TeV-made with the Water Cherenkov Detector Array (WCDA) of the Large High Altitude Air Shower Observatory. After the sky regions of known sources are masked, the diffuse emission is detected with 24.

Background: In developing settings, comparative data on COVID hospitalised survivors (HS) and non-hospitalised survivors (NHS) is scarce. We determined burdens, incidence, evolution, and associated factors of long COVID-19 over two years among these groups.

Methods: We conducted a longitudinal cohort study in Dhaka, Bangladesh, and recruited confirmed COVID-19 survivors from December 2020 to May 2021 (previously reported).

Focus of this study is on the use of the hydrazone compound (3) (N-(4-bromobenzylidene)-4-(1H-indol-3-yl) butane hydrazide), which was previously prepared from the reaction of the compound p-bromobenzaldehyde with the corresponding hydrazide (2), as an intermediate compound for the synthesis of azetidine, thiazolidine, tetrazole, oxadiazole and phthalazine heterocyclic compounds through its reaction with some cyclic reagents and catalysts such as chloro acetyl chloride, thioglycolic acid, sodium-azid, lead dioxide and Hydrogen chloride gas. The prepared compounds were characterized using physical properties and also spectroscopic methods such as infrared spectroscopy, nuclear magnetic resonance spectra of the proton and the isotope of carbon as well as mass spectrometry, which accurately identified the proposed structures of the prepared compounds. The identity of the prepared compounds was determined using physical and spectroscopic properties, where infrared and HNMR spectroscopy of the proton as well as carbon were used in addition to using mass spectrometry to verify the validity of the prepared structures.
