The present work deals with the simultaneous ultrastructure and triple immunofluorescence study of the three main hepatic fibrogenic cells, hepatic stellate cell, myofibroblast (MF), and fibroblast, in a group of hepatitis C virus (HCV) RNA positive patients, as their exact interrelation behavior in vivo with the progress of hepatic fibrosis is still inadequate. In this study, for the first time, cells having the morphological characteristic of MF and not bone marrow fibrocytes were revealed in liver portal vessels. This necessitates the reevaluation of the available knowledge concerning bone marrow fibrocyte. Also, the distribution, cellular interrelations, and the fate of MF were highlighted.

Understanding the behavior of populations of drug consumers has been and remains a topic of keen interest. Using a unique dataset on 25 districts from Bengal, India, from 1911 to 1925, we analyze whether populations of consumers treat alcohol, cannabis, and opium as economic substitutes or complements in a legal regime. Additionally, we examine responsiveness to prices and income.

BACKGROUND Different temperature conditions can affect the efficiency of irrigation solutions and consequently the ability of canal sealers to bond to root canal walls. The aim of this endodontic study was to evaluate the effect of irrigation solutions at different temperatures on the bond strength of a bioceramic-based root canal sealer. MATERIAL AND METHODS Root canal preparations were completed through irrigation with the following solutions: Group 1 was irrigated with 5 ml NaOCl (sodium hypochlorite) +5 ml EDTA (Ethylenediamine tetra-acetic acid) (22°C); Group 2 was irrigated with 5 ml NaOCl +5 ml EDTA (37°C); Group 3 was irrigated with 5 ml NaOCl +5 ml GA (Glycolic acid) (22°C); Group 4 was irrigated with 5 ml NaOCl +5 ml GA (37°C), Group 5 was irrigated with 20 ml Dual Rinse® HEDP (Etidronate) - NaOCl mixture (22°C); and Group 6 was irrigated with 20 ml of Dual Rinse® HEDP mixture (37°C).

Nitric oxide (NO) is an important signaling molecule that is involved in stress response, homeostasis, host defense, and cell development. In most cells, NO levels are in the femtomolar to micromolar range, with extracellular concentrations being much lower. Thus, real time measurement of spatiotemporal NO dynamics near the surface of living cells/tissues is a major challenge.

Background: African Americans experience cardiovascular disease (CVD) disparities, and the burden is greatest in the rural south. Although evidence-based CVD prevention and management programs have been tailored to this context, implementation has been limited and not sustained long-term. To understand how to implement and sustain evidence-based CVD programs at scale, we must explore the perspectives of organizations serving rural African American communities and situate findings within foundational Implementation Science frameworks.

Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.
Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.
