Opioids are widely used as therapeutic agents against moderate to severe acute and chronic pain. Still, these classes of analgesic drugs have many potential limitations as they induce analgesic tolerance, addiction and numerous behavioural adverse effects that often result in patient non-compliance....

An ethnomedicinal survey conducted in two sub-districts (upazillas) each of three districts of Bangladesh revealed that there is both inter- and intra-district variation between the choices of medicinal plants selected by folk medicinal healers (kavirajes) to treat any specific ailment. The variatio...

This paper presents a highly sensitive plasmonic refractive index (RI) sensor on a dual-core photonic crystal fiber (PCF). The performance of the RI sensor is weighed in terms of amplitude sensitivity, wavelength sensitivity, wavelength resolution, and linearity of the resonance wavelength. Numerica...

In this paper, two exclusive surface plasmon resonance (SPR) biosensors are proposed numerically utilizing the newly emerged transition metal dichalcogenides (e.g. PtSe2) composed with 2D materials (e.g. Graphene, MoS2 and WS2) onto the traditional SPR biosensors. The performance of the sensors is i...

Disease epidemics in shrimp aquaculture increase apace with the development of aquaculture systems throughout the world. The disease caused by Vibrio spp. (vibriosis) is considered the most devastating, which has made it the most feared bacterial disease in the shrimp sector. In aquaculture, several...

Seasonal and tidal variations in nutrient concentration and water quality were investigated in the western Sundarbans of Bangladesh during the post-monsoon, winter and monsoon seasons during 2010–2011. Water collected from the surface, middle and bottom layers at six locations of the Kholpetua-Arpan...

The distribution, enrichment, and ecotoxicity potential of Bangladesh part of Sundarban mangrove was investigated for eight trace metals (As, Cd, Cr, Cu, Fe, Mn, Pb, and Zn) using sediment quality assessment indices. The average concentration of trace metals in the sediments exceeded the crustal abu...

Cancer is a chronic disease, and it can be lethal due to limited therapeutic options. The conventional treatment options for cancer have numerous challenges, such as a low blood circulation time as well as poor solubility of anticancer drugs. Therapeutic cancer vaccines emerged to try to improve ant...
