Hepatitis B virus (HBV) infection is a major risk factor for chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. While multiple hepatitis B drugs have been developed, development of drug resistance during treatment or weak efficacies observed in some cases have limited their application. Therefore, there is an urgent need to develop better pharmacological agents for HBV-infected individuals. Here, we identified cetylpyridinium chloride (CPC) as a novel inhibitor of HBV. Using computational analysis of CPC-nucleocapsid proteins, microscale thermophoresis analysis of CPC binding to viral nucleocapsids, and in vitro nucleocapsid formation assays, we found that CPC interacts with dimeric viral nucleocapsid protein (known as core protein or HBcAg)...

Evidence suggests that many G protein-coupled receptors (GPCRs) are bound together forming dimers. The implications of dimerisation for cellular signalling outcomes, and ultimately drug discovery and therapeutics, remain unclear. Consideration of ligand binding and signalling via receptor dimers is therefore required as an addition to classical receptor theory, which is largely built on assumptions of monomeric receptors. A key factor in developing theoretical models of dimer signalling is cooperativity across the dimer, whereby binding of a ligand to one protomer affects the binding of a ligand to the other protomer...

Fibroblast activation protein-α (FAPα) is a promising tumor-associated target expressed by reactive stromal fibroblasts in tumor tissue. FAPα has a postprolyl peptidase activity and can specifically cleave N-terminal benzyloxycarbonyl (Z)-blocked peptides, such as the substrate Z-Gly-Pro-AMC. Doxorubicin (DOX) is an effective antitumor drug, but its application is greatly limited by toxic adverse effects owing to poor tumor selectivity. Based on these facts, we previously designed a FAPα-targeting prodrug of doxorubicin (FTPD) which can be selectively hydrolyzed by FAPα...

Paracetamol (acetaminophen or N-acetyl-p-aminophenol) is considered a safe analgesic and antipyretic nonsteroidal antiinflammatory drug commonly used during pediatric ages and during pregnancy. We report on a term neonate with closed ductus arteriosus, severe cardiomyopathy, right ventricular dysfunction, and functional stenosis of pulmonary arteries at birth after maternal self-medication with paracetamol and consumption of polyphenol-rich foods in late pregnancy. This drug, especially when associated with other vasoconstrictors (such as polyphenols), interferes with prostaglandin metabolism, which seriously accentuates the intrauterine ductus arteriosus constriction and leads to pharmacologic adverse events...

BACKGROUND: The severe form of equine asthma is associated with pathological changes of the peripheral airways and pulmonary parenchyma that are only partly described. Also, the relationship between these structural alterations and the percentage of neutrophils found within the airway lumen, assessed by bronchoalveolar lavage fluid (BALF) cytology, remains ill-defined. OBJECTIVE: To examine the histological lesions associated with equine asthma during disease exacerbation and remission, and their relationship with lung function and BALF neutrophilia...

BACKGROUND: Hypertensive urgency (HU), defined as acute severe uncontrolled hypertension without end-organ damage, is a common condition. Despite its association with long-term morbidity and mortality, guidance regarding immediate management is sparse. Our objective was to summarize the evidence examining the effects of antihypertensive medications to treat. METHODS: We searched the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Database of Abstracts of Reviews of Effects (DARE), Cochrane Database of Systematic Reviews, Web of Science, Google Scholar, and Embase through May 2016...

Varices manifest as a major etiology of upper gastrointestinal bleeding in patients with chronic liver diseases, such as liver cirrhosis and hepatocellular carcinoma. By contrast, non-variceal upper gastrointestinal bleeding is rare. Pharmacological treatment differs between patients with variceal and non-variceal bleeding. Vasoconstrictors are recommended for the treatment of variceal bleeding, rather than non-variceal bleeding. In contrast, pump proton inhibitors are recommended for the treatment of non-variceal bleeding, rather than variceal bleeding...

Vestibular schwannoma and endolymphatic hydrops are two conditions that may present with similar audio-vestibular symptoms. The association of the two in the same patient represents an unusual finding that may lead clinicians to errors and delays in diagnosis and clinical management of affected subjects. We discuss the case of a patient with an intrameatal vestibular schwannoma reporting symptoms suggestive for ipsilateral endolymphatic hydrops. The patient presented with fluctuating hearing loss, tinnitus, and acute rotatory vertigo episodes, and underwent a full audiological evaluation and imaging of the brain with contrast-enhanced Magnetic Resonance Imaging...

REVIEW
Marcos Roberto de Oliveira
Carnosic acid (CA; C20H28O4), a phenolic diterpene characterized as an ortho-dihydroquinone-type molecule, is a pro-electrophile agent that becomes an electrophile after reacting with free radicals. The electrophile generated from CA interacts with and activates the nuclear factor erythroid 2-related factor 2 (Nrf2) transcription factor, which is a major modulator of redox biology in mammalian cells. CA induces antioxidant and anti-inflammatory effects in several cell types, as observed in both in vitro and in vivo experimental models...
