INTRODUCTION: Adult vaccination coverage rates in the US are well below national targets, leaving many adults at increased risk. Additionally, typical vaccination coverage calculations do not adequately approximate population immunity as they do not consider whether multidose vaccines were administered within the recommended schedules. As timely administration of each dose optimizes overall vaccine effectiveness, we sought to document adherence to and completion of the hepatitis A (HepA), hepatitis B (HepB), and combined hepatitis A and hepatitis B (HepA-HepB) multidose vaccine schedule in an insured adult population in the US...

OBJECTIVE: The exposure to artificial light at night (ALAN) disrupts the biological rhythms and has been associated with the development of metabolic syndrome. MicroRNAs (miRNAs) display a critical role in fine-tuning the circadian system and energy metabolism. In this study, we aimed to assess whether altered miRNAs expression in the liver underlies metabolic disorders caused by disrupted biological rhythms. RESULTS: We found that C3H/HePas mice exposed to ALAN developed obesity, and hepatic steatosis, which was paralleled by decreased expression of Rev-erbα and up-regulation of its lipogenic targets ACL and FAS in liver...

The recently developed three-dimensional (3D) graphene foam (GrF) is intriguing for potential bone tissue engineering applications because it provides stem cells with a 3D porous substrate for osteogenic differentiation. However, the nature of graphene's structure lacks functional groups, thus making it difficult for further modification such as immobilization or conjugation of growth factors, which are normally required to promote tissue regeneration. To explore the potential of GrF functionalization and sustained release of therapeutic proteins, we fabricated a modified 3D GrF scaffold with bio-inspired heparin-dopamine (Hepa-Dopa) molecules using a highly scalable chemical vapour deposition method...

Particulate matter (PM) exposure may contribute to depressive-like response in mice. However, few studies have evaluated the adaptive impacts of long-term PM exposure on depressive-like response associated with systemic inflammation and brain-derived neurotrophic factor (BDNF) signaling pathway. We studied the association among depressive-like behaviors, mRNA levels of pro- and anti-inflammatory cytokines, and the expression of BDNF signaling pathway in mice by long-term PM exposure. C57BL/6 male mice were exposed to ambient air alongside control mice breathing air filtered through a high-efficiency air PM (HEPA) filter...

INTRODUCTION: Hepatitis A can cause widespread outbreaks. Until 2018, postexposure prophylaxis (PEP) in the United States for individuals >40 years consisted of immune globulin (IG) administered as soon as possible after exposure, ideally within 14 days whereas those aged ≤40 should receive hepatitis A (HepA) vaccine. However, state health departments reporting difficulty quickly accessing and administering IG, costs of higher IG doses and importance of long-term HAV protection prompted CDC to review immunogenicity data for use of HepA vaccine for PEP in older adults...

Carboxylesterases (CES) are a family of phase I enzymes that play an important role in xenobiotic clearance and lipid metabolism. Here, we investigate a potential role of E4 promoter-binding protein 4 (E4bp4) in regulation of Ces and CPT-11 (irinotecan, a first-line drug for treating colorectal cancer) pharmacokinetics in mice. Mouse hepatoma Hepa-1c1c7 cells were transfected with Rev-erbα expression plasmid or siRNA targeting E4bp4. The relative mRNA and protein levels of Ces enzymes in the cells or the livers of wild-type and E4bp4-deficient (E4bp4-/- ) mice were determined by qPCR and Western blotting, respectively...

Tuberculosis has spread by human movements throughout history. There have been reports indicating tuberculosis transmission on all travel vehicles, including aircrafts, ground vehicles and vessels until today. However, due to the ever increasing of air transportation and air travelling among countries with low and high tuberculosis incidence, transmission risk especially in aircrafts has become an important issue worldwide. But in many of the studies conducted in this regard, transmission of tuberculosis in aircrafts was found very low...

Various species of cyanobacteria, diatoms and dinoflagellates are capable of synthesizing the non-proteinogenic neurotoxic amino acid β-N-methylamino-L-alanine (BMAA), which is known to be a causative agent of human neurodegeneration. Similar to most cyanotoxins, the biological and ecological functions of BMAA in cyanobacteria are unknown. In this study, we show for the first time that BMAA, in micromolar amounts, inhibits the formation of heterocysts (specialized nitrogen-fixing cells) in heterocystous, diazotrophic cyanobacteria [Anabaena sp...

Liver cancer is mainly originated by cancer stem cells (CSCs). Due to difference in pH between normal and tumor cell microenvironments, targeting hepatic CSCs exploiting pH-dependent charge switchable nanoparticles (NPs) is extremely required to limit nonselective toxicity to normal hepatocytes (NHCs) and to completely eliminate the root of cancer origin. In this study, NPs were prepared from cationic chitosan and then coated with anionic albumin namely uncoated and coated NPs, respectively. Both NPs were loaded with diethyldithiocarbamate (DDC) which is an inhibitor of the critical enzyme, aldehyde dehydrogenase (ALDH) 1A1, for CSCs survival...
