The initiation of ferrite nanoparticles has changed the perception of nanotechnology in the biomedical field especially magnetic hyperthermia based application. Wet chemical co-precipitation method has been used to synthesize chitosan-coated Co1−xMnxFe2O4 (0.0 ≤ x ≤ 1.0, in the steps of 0.2) nano fe...

Chest radiographs (X-rays) combined with Deep Convolutional Neural Network (CNN) methods have been demonstrated to detect and diagnose the onset of COVID-19, the disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). However, questions remain regarding the accuracy of th...

Optimum sintering temperature (Ts) plays an important role in controlling densification and growth of grains which greatly affect the magnetic and electrical properties of polycrystalline materials. Y-substituted Mg-Zn [Mg0.5Zn0.5YxFe2−xO4 (0 ≤ x ≤ 0.05)] ferrites have been prepared by using convent...

Genetic and neurobiological factors are considered to be the major causes of mood and mental disorders. However, over the past few years, increased levels of serum malondialdehyde and altered levels of various non-enzymatic antioxidants and essential minerals involved in abnormal functional activity...

Abstract We report the synthesis of Y-substituted Mg–Zn [Mg 0.5 Zn 0.5 Y x Fe 2− x O 4 (0 ≤ x ≤ 0.05)] ferrites using conventional standard ceramic technique. The samples were characterized by x-ray diffraction (XRD) analysis, field emission scanning electron microscopy (FESEM), FTIR spectroscopy, U...

BACKGROUND: Seasonal and avian influenza viruses circulate among human and poultry populations in Bangladesh. However, the epidemiology of influenza is not well defined in this setting. We aimed to characterise influenza seasonality, examine regional heterogeneity in transmission, and evaluate cosea...

Genomics, combined with population mobility data, used to map importation and spatial spread of SARS-CoV-2 in high-income countries has enabled the implementation of local control measures. Here, to track the spread of SARS-CoV-2 lineages in Bangladesh at the national level, we analysed outbreak tra...

Hyperthermia opens a safe alternative for cancer treatment. Researchers synthesize new materials that can be successfully used for the biomedical application. We have synthesized Mn1-xZnxFe2O4 (0.2 ≤ x ≤ 1.0, in the steps of 0.2) and coated the samples with chitosan. The structural properties of the...

Bangladesh reported the highest number of annual deaths (n = 281) related to dengue virus infection in 2022 since the virus reappeared in the country in 2000. Earlier studies showed that >92% of the annual cases occurred between the months of August and September. The 2022 outbreak is characterized ...
