Ruptured Liver Abscess Post Severe COVID-19 Infection: A Case Report.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) caused imminent acute infection of respiratory tract known as Coronavirus disease 2019 (COVID-19). Complications of hepatobiliary system especially liver often found in post-acute COVID-19 patients. However, there are only few studies specifically discussing about liver abscess in patients who had history of contracted COVID-19.

Quantification of mesenchymal stem cell growth rates through secretory and excretory biomolecules in conditioned media via Fresnel reflection.

An efficient and low cost optical method for directly measuring the concentration of homogenous biological solutes is proposed and demonstrated. The proposed system operates by Fresnel reflection, with a flat-cleaved single-mode fiber serving as the sensor probe. A laser provides a 12.

Highly stable graphene-assisted tunable dual-wavelength erbium-doped fiber laser.

A highly stable tunable dual-wavelength fiber laser (TDWFL) using graphene as a means to generate a highly stable output is proposed and generated. The TDWFL comprises a 1 m long, highly doped erbium-doped fiber (EDF) acting as the linear gain medium, with a 24-channel arrayed waveguide grating acting as a wavelength slicer as well as a tuning mechanism to generate different wavelength pairs. The tuned wavelength pairs can range from 0.
