Chronic HBV Infection Disrupts CCL5‐Secreting cNK Cells and Attenuates Liver Accumulation and Activation of DCs and HBV‐Specific T Cells

open access: yesAdvanced Science, EarlyView.
ADORA2A activation suppresses NFκB‐dependent CCL5 production in cNK cells during chronic HBV infection, disrupting intrahepatic DC recruitment and HBV‐specific CD8+ T‐cell differentiation and function. Targeting the ADORA2A/NFκB/CCL5 axis restores antiviral immunity and facilitates HBV clearance.

Mercury and lead pollution in rivers in Ghana: geo-accumulation index, contamination factor, and water quality index

open access: yesWater Practice and Technology, 2023
Abstract The main environmental problem in Kumasi is water pollution, but little is done about this. Neither water quality nor the degree of heavy metal contamination in Kumasi has been assessed. The degree of mercury and lead pollution in Kumasi was investigated in this study by determining the geo-accumulation index ...

Geo-accumulation index and contamination factors of heavy metals (Zn and Pb) in urban river sediment [PDF]

open access: yesEnvironmental Geochemistry and Health, 2017
The aim of the present study was to appraise the levels of heavy metal contamination (Zn and Pb) in sediment of the Langat River (Selangor, Malaysia). Samples were collected randomly from 15 sampling stations located along the Langat River. The parameters measured were pH, redox potential, salinity, electrical conductivity, loss of ignition, cation ...
