This paper proposes a dynamic model to describe and forecast the dynamics of the coronavirus disease COVID-19 transmission.The model is based on an approach previously used to describe the Middle East Respiratory Syndrome (MERS) epidemic.This methodology is used to describe the COVID-19 dynamics in six countries where the pandemic is widely spread,
Background: A superior mesenteric arteriovenous fistula (SMAVF) is a rare, aberrant connection between the superior mesenteric artery (SMA) and the superior mesenteric vein (SMV).Management includes either open surgical repair or endovascular repair with embolization coils or covered stents.We report a novel STEVIA in-stent coil embolization techni
Summary: Currently, strop patients receiving cancer treatments routinely suffer from distressing toxic effects, most originating from premature drug leakage, poor biocompatibility, and off-targeting.For tackling this challenge, we construct an intracellular Ca2+ cascade for tumor therapy via photothermal activation of TRPV1 channels.The nanoplatfor
Abstract As a key component of electron multiplier device, a microchannel plate (MCP) can be applied in many scientific fields.Pure aluminum oxide (Al2O3) FERMENTED PROTEINS as secondary electron emission (SEE) layer were deposited in the pores of MCP via atomic layer deposition (ALD) to overcome problems such as high dark current and low lifetime
There is a large gap between diagnostic needs and diagnostic access across much of sub-Saharan Africa (SSA), particularly for infectious diseases that inflict a substantial burden of morbidity and mortality.Accurate diagnostics are essential for the correct treatment of individuals and provide vital information underpinning disease surveillance, pr
