Purpose: The pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF), might be altered in patients with acute lymphoblastic leukemia (ALL), affecting the optimum dose needed for hepatitis C virus treatment. Limited data are available evaluating the population PK of LDV/SOF and SOF metabolite GS-331007. We aimed to study whether ALL could affect population PK parameters of LDV, SOF, and the SOF major metabolite GS-331007 in hepatitis C virus-infected children, develop and validate a predictive PK model of LDV/SOF disposition in this special population, and identify their explained and unexplained sources of variability.

Hybridisation of the cavity modes and the excitons to polariton states together with the coupling to the vibrational modes determine the linear optical properties of organic semiconductors in microcavities. In this article we compute the refractive index for such system using the Holstein-Tavis-Cummings model and determine then the linear optical properties using the transfer matrix method. We first extract the parameters for the exciton in our model from fitting to experimentally measured absorption of a 2,7-bis[9,9-di(4-methylphenyl)-fluoren-2-yl]-9,9-di(4-methylphenyl) fluorene (TDAF) molecular thin film.

Modifying the energy landscape of existing molecular emitters is an attractive challenge with favourable outcomes in chemistry and organic optoelectronic research. It has recently been explored through strong light-matter coupling studies where the organic emitters were placed in an optical cavity. Nonetheless, a debate revolves around whether the observed change in the material properties represents novel coupled system dynamics or the unmasking of pre-existing material properties induced by light-matter interactions.

Article Synopsis
  • In 2021, symptomatic dry bean plants were collected near the Pembina - Emerson Border showing signs of wilting, leaf discoloration, and poor growth, alongside brown to black discoloration on stems and roots.
  • The affected root and stem pieces were sterilized and cultured on potato dextrose agar, revealing the growth of a fungus that transitioned from light gray to dark brown or black.
  • The fungus was identified as Macrophomina phaseolina through morphological examination and genetic sequencing, confirming its identity with 100% match on a database search.

Purpose: Children with hematological malignancies and chronic hepatitis C virus (HCV) infection are at a higher risk for rapid progression of liver disease and malignancy relapse due to multiple hepatitis flares and chemotherapy interruption. They are therefore potential candidates for microelimination of HCV infection. This study aimed to assess the effect of acute lymphoblastic leukemia (ALL) on the pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF) and the SOF major metabolite GS-331007.

This study intends to enhance the mechanical strength of wood-plastic composite selective laser sintering (SLS) parts by using a sustainable composite, peanut husk powder (PHP)/poly ether sulfone (PES) (PHPC). The study aims to address agricultural waste pollution by encouraging the eco-friendly utilization of such waste in SLS technology. To ensure the sintering quality and mechanical properties and prevent deformation and warping during sintering, the thermo-physical properties of PHP and PES powders were analyzed to determine a suitable preheating temperature for PHPC.

Improving the performance of organic optoelectronics has been under vigorous research for decades. Recently, polaritonics has been introduced as a technology that has the potential to improve the optical, electrical, and chemical properties of materials and devices. However, polaritons have been mainly studied in optical microcavities that are made by vacuum deposition processes, which are costly, unavailable to many, and incompatible with printed optoelectronics methods.
