Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide with an estimated number of 2.7-6.1 million cases in the United States (US) alone. The incidence of AF is expected to increase 2.5 fold over the next 50 years in the US. The management of AF is complex and includes mainly three aspects; restoration of sinus rhythm, control of ventricular rate and prevention of systemic thromboembolism. AF as a cause of systemic embolization has been well known for many years, and majority of patients are on oral anticoagulants (OACs) to prevent this...

Jie Sun, Ke Chen
Nucleotides play a central role in life-form metabolism, by interacting with proteins and mediating the function of proteins. It is estimated that nucleotides constitute about 15% of the biologically relevant ligands included in PDB. Prediction of binding sites of nucleotides is useful in understanding the function of proteins and can facilitate the in silico design of drugs. In this study, we propose a nucleotide-binding site predictor, namely, NSiteMatch. The NSiteMatch algorithm integrates three different strategies: geometrical analysis, energy calculation, and template comparison...

In patients with home ventilation, there is a markedly higher probability for lower respiratory infections or pneumonia and severe courses due to comorbidity. Tracheobronchitis and pneumonia are often difficult to distinguish. Tracheobronchitis with pronounced secretion which can't be controlled otherwise can be an indication for antimicrobial therapy.There are no data available in order to establish a recommendation for the initial empiric calculated antimicrobial therapy in patients with home ventilation...

BACKGROUND: Advances in pharmaceuticals offer improved health outcomes for a wide range of illnesses, yet medicines are often inaccessible for many patients worldwide. One potential barrier to making medicines available to all is the cost of product registration, the fees for regulatory review and licensing for the sale of medicines beyond the cost of clinical trials, if needed. METHODS AND FINDINGS: We performed a cross-sectional analysis of pharmaceutical registration fees in low-, middle-, and high-income countries...

Shanshan Liu, Paul C Ho
OBJECTIVES: Scutellarin (SCU) is a traditional Chinese medicine used for the treatment of ischaemic cerebrovascular disease, but its clinic applications have been limited due to its poor water solubility, poor bioavailability and short half-life. In comparison with the conventional oral and intravenous administration, nasal administration may help targeting the drug more directly to brain. Thus, we proposed to employ a novel SCU-loaded HP-β-CD/chitosan nanoparticles (CD/CS-SCU-NPs) to deliver SCU to brain through the nasal route...

Although antibacterial therapy has an impact on human intestinal flora and emergence of resistant bacteria, its role on amplification of antimicrobial resistance and the quantitative exposure-effect relationship is not clear. An observational prospective study was conducted to determine whether and how ceftriaxone exposure is related to amplification of resistance in non- ICU patients.Serial stool samples from 122 ESBL(+) hospitalized patients were analyzed with quantitative real-time PCR to quantify the resistant gene blaCTX-M Drug exposure was calculated for each patient using a population pharmacokinetic model...

Anthelmintic resistance in sheep gastrointestinal nematodes is a worldwide problem. Multi-drug resistant haemonchosis is the most serious impediment for small ruminant systems, and there are no new drug candidates currently under development. Molecules from natural sources have demonstrated anthelmintic activity against parasites. In this work, the monoterpenoids carvacrol, carvone, cineole, linalool, limonene, and thymol and the phenylpropanoids cinnamaldehyde, anethole, vanillin, and eugenol were assessed individually or in mixtures of ten binary, three ternary, and three quaternary combinations using the in vitro egg hatch assay with eggs of a multi-drug resistant strain of Haemonchus contortus...

Dave M Leathwick, Dongwen Luo
The concentration profile of anthelmintic reaching the target worms in the host can vary between animals even when administered doses are tailored to individual liveweight at the manufacturer's recommended rate. Factors contributing to variation in drug concentration include weather, breed of animal, formulation and the route by which drugs are administered. The implications of this variability for the development of anthelmintic resistance was investigated using Monte-Carlo simulation. A model framework was established where 100 animals each received a single drug treatment...

REVIEW

BACKGROUND: Acetylcholinesterase inhibitors, such as neostigmine, have traditionally been used for reversal of non-depolarizing neuromuscular blocking agents. However, these drugs have significant limitations, such as indirect mechanisms of reversal, limited and unpredictable efficacy, and undesirable autonomic responses. Sugammadex is a selective relaxant-binding agent specifically developed for rapid reversal of non-depolarizing neuromuscular blockade induced by rocuronium. Its potential clinical benefits include fast and predictable reversal of any degree of block, increased patient safety, reduced incidence of residual block on recovery, and more efficient use of healthcare resources...

Bio-compatible gold nanoclusters can be utilized as contrast agents in virus imaging. The labeling of viruses can be achieved non-covalently but site-specifically by linking the cluster to the hydrophobic pocket of a virus via a lipid-like pocket factor. We have estimated the binding affinities of three different pocket factors of echovirus 1 (EV1) in molecular dynamics simulations combined with non-equilibrium free energy calculations. We have also studied the effects on binding affinities with a pocket factor linked to the Au102pMBA44 nanocluster in different protonation states...

Telmisartan, an angiotensin receptor blocker (ARB), is indicated for the treatment of essential hypertension. This study aimed to develop a mechanistic model of telmisartan drug effect in human using non-invasive markers. Data were acquired from a previous study where telmisartan 80 mg was given once daily for 6 days. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were measured before dosing for day 1 to 5 and serially after the last dose. Mean arterial pressure (MAP) and pulse pressure (PP) were calculated from SBP and DBP...

The dopamine D2 Receptor (D2R) is a member of the G-Protein Coupled Receptor (GPCR) family and plays a critical role in neurotransmission activities in the human brain. Dysfunction in dopamine receptor signaling may lead to mental health illnesses such as schizophrenia and Parkinson's disease. D2R is the target protein of the commonly used anti-psychotic drugs such as risperidone, clozapine, aripiprazole, olanzapine, ziprasidone and quetiapine. Due to their significant side effects and nonselective profiles, the discovery of novel drugs has become a challenge for researchers working in this field...

Various approaches have been undertaken to enhance the delivery of therapeutic agents, including tissue-killing radionuclides, into solid tumors. Here we describe the preparation of conical needles composed of Ti and Mo coated by pulsed laser deposition or chemical vapor deposition with elements (Ho and Re) that can readily yield radioactive isotopes following irradiation in a neutron flux. The radioactive needles, whose design were based on solid microneedle arrays used in transdermal drug delivery, can be produced with minimal handling of radioactivity and subsequently inserted into tumors as a means of internal radiation therapy...
