REVIEW
Klaus Linde, Karin Rossnagel
BACKGROUND: Propranolol is one of the most commonly prescribed drugs for migraine prophylaxis. OBJECTIVES: We aimed to determine whether there is evidence that propranolol is more effective than placebo and as effective as other drugs for the interval (prophylactic) treatment of patients with migraine. SEARCH METHODS: Potentially eligible studies were identified by searching MEDLINE/PubMed (1966 to May 2003) and the Cochrane Central Register of Controlled Trials (Issue 2, 2003), and by screening bibliographies of reviews and identified articles...

This study aimed to investigate the pharmaceutical performance of an indomethacin-polyvinylpyrrolidone (PVP) glass solution applied using fluid bed processing as a layer on inert sucrose spheres, and subsequently top-coated with a release rate controlling membrane consisting of either ethyl cellulose or Eudragit RL. The implications of the addition of a pore former (PVP) and the coating medium (ethanol or water) on the diffusion and release behavior were also considered. In addition, the role of a charge interaction between drug and controlled release polymer on the release was investigated...

OBJECTIVE: Driven by advances in genomic technology and reduction in costs, next-generation sequencing (NGS) is venturing into routine clinical care. The 'real-world' clinical utility of NGS remains to be determined in focal epilepsies, which account for 60% of all epilepsies and for which the importance of genetic factors is just beginning to emerge. We investigated the diagnostic yield and management implications of whole exome sequencing (WES)-based screening of selected genes in the routine care of common focal epilepsies suspected to have a genetic basis...

The peroxisome proliferator activator receptor-γ (PPAR-γ) remained the most successful target for management of diabetes mellitus. The present work endeavors rational designing of some novel PPAR-γ agonists bearing benzylideneamino-benzylidene-thiazolidine-2,4-dione scaffold. The research involved virtual screening of 37 different molecules by molecular docking studies performed by Molecular Design Suite (MDS) into the ligand binding domain of PPAR-γ receptor to explore the binding affinity and conformations of the molecules...

BACKGROUND: Linezolid, an oxazolidinone, substantially improves treatment outcomes of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. We started a trial to test whether the use of linezolid instead of ethambutol could increase the rate of sputum culture conversion as of 8 weeks of treatment in patients with drug-susceptible tuberculosis. METHODS/DESIGN: This is a phase II, multicenter, randomized study with three arms. We are enrolling patients with pulmonary tuberculosis without rifampicin resistance screened by the Xpert MTB/RIF® assay...

Steering the differentiation of induced pluripotent stem cells (iPSCs) toward specific cell types is crucial for patient-specific disease modeling and drug testing. This effort requires the capacity to predict and control when and how multipotent progenitor cells commit to the desired cell fate. Cell fate commitment represents a critical state transition or "tipping point" at which complex systems undergo a sudden qualitative shift. To characterize such transitions during iPSC to cardiomyocyte differentiation, we analyzed the gene expression patterns of 96 developmental genes at single-cell resolution...

Cryptococcus neoformans is a common pathogen of the immunosuppressed. It can be treated with amphotericin B and fluconazole, but the mortality rate remains 15-30%, thus novel and more effective anti-cryptococcal therapies are needed. The troponoids are based on natural products isolated from Western redcedar and have broad antimicrobial activity. Extracts of Western redcedar inhibit growth of several fungal species, but neither Western redcedar extracts nor troponoid derivatives have been tested against C. neoformans...

BACKGROUND: While cocaine use is an established risk factor for acute cardiovascular complications, associations between cocaine use and markers of cardiac injury outside of acute hospital presentation remain poorly characterized. We leveraged advances in cardiac troponin (cTnI) testing to assess low but clinically meaningful levels of cardiac injury among cocaine users and non-users. METHODS: We conducted a case control study comparing cTnI levels by the presence of cocaine among patients presenting for non-cardiac care in an urban safety net hospital...

BACKGROUND: Transcription factors are known to play key roles in carcinogenesis and therefore, are gaining popularity as potential therapeutic targets in drug development. A 'master regulator' transcription factor often appears to control most of the regulatory activities of the other transcription factors and the associated genes. This 'master regulator' transcription factor is at the top of the hierarchy of the transcriptomic regulation. Therefore, it is important to identify and target the master regulator transcription factor for proper understanding of the associated disease process and identifying the best therapeutic option...

Idiopathic pulmonary fibrosis (IPF) is a fatal progressive fibrotic lung disease characterized by the presence of invasive myofibroblasts in the lung. Currently, there are only two FDA-approved drugs (pirfenidone and nintedanib) for the treatment of IPF. There are no defined criteria to guide specific drug therapy. New methodologies are needed not only to predict personalized drug therapy, but also to screen novel molecules that are on the horizon for treatment of IPF. We have developed a model system that exploits the invasive phenotype of IPF lung tissue...

In any drug discovery and development effort, reduction in the lead optimization cycle is critical to decrease the time to license and reduce cost. In addition, ethical guidelines call for more ethical use of animals to minimize the number of animals used and decrease their suffering. Therefore, any cutaneous Leishmaniasis drug development effort requires multiple tiers of in vivo testing that start with higher-throughput efficacy assessments and progress to lower-throughput models with the most clinical relevance...

Drug resistance among bacteria is a scourge to patients and infectious disease and infection control specialists. The rapid detection of resistance is a challenge for clinical microbiologists who wish to prevent deleterious individual and collective consequences such as (i) delaying efficient antibiotic therapy, which worsens the survival rate of the most severely ill patients, or (ii) delaying the isolation of the carriers of multidrug-resistant bacteria and promoting outbreaks; this last consequence is of special concern, and there are an increasing number of approaches and market-based solutions in response...

Antiangiogenic drugs encompass many of the different cancer drugs currently under clinical investigation. One of the drawbacks of antiangiogenic therapy, though, is that upon cessation of drug treatment tumors can recur with an accelerated growth rate. In this study we investigate the capacity of using affinity interactions between a polymer made from cyclodextrin and four antiangiogenic drugs, tranilast, SU5416, 2-methoxyestradiol, and silibinin, with the ultimate goal of creating delivery profiles on the order of antiangiogenic processes (needing weeks, rather than hours of delivery)...

INTRODUCTION: To date there is no cure for Alzheimer's disease (AD). After amyloid beta immunotherapies have failed to meet primary endpoints of slowing cognitive decline in AD subjects, the inhibition of the beta-secretase BACE1 appears as a promising therapeutic approach. Pre-clinical data obtained in APP23 mice suggested that the anti-cancer drug thalidomide decreases brainBACE1 and A levels. This prompted us to develop an NIH-supported Phase IIa clinical trial to test the potential of thalidomide for AD...

Antiretroviral therapy (ART) can control HIV-1 replication in infected individuals. Unfortunately, patients remain persistently infected owing to the establishment of latent infection requiring that ART be maintained indefinitely. One strategy being pursued involves the development of latency reversing agents (LRAs) to eliminate the latent arm of the infection. One class of molecules that has been tested for LRA activity is the epigenetic modulating compounds histone deacetylases inhibitors (HDACis). Previously, initial screening of these molecules typically commenced using established cell models of viral latency, and although certain drugs such as the HDACi SAHA demonstrated strong activity in these models, it did not translate to comparable activity with patient samples...

BACKGROUND AND AIMS: High rates of loss to follow-up represent a significant challenge to clinical trials of pharmacologic treatments for methamphetamine (MA) use disorder. We aimed to estimate and test the relationship between achieving and maintaining abstinence in the initial weeks of study participation and subsequent retention in such trials, hypothesizing that participants able to achieve early abstinence would be less likely to drop out. DESIGN: Data from four randomized controlled trials (RCTs) of pharmacologic treatments for MA use disorder were pooled and analyzed using a random-effects approach...

BACKGOUND: Fusarium graminearum (FG) is one of the major cereal infecting pathogens causing high economic losses worldwide and resulting in adverse effects on human and animal health. Therefore, the development of new fungicides against FG is an important issue to reduce cereal infection and economic impact. In the strategy for developing new fungicides, a critical step is the identification of new targets against which innovative chemicals weapons can be designed. As several G-protein coupled receptors (GPCRs) are implicated in signaling pathways critical for the fungi development and survival, such proteins could be valuable efficient targets to reduce Fusarium growth and therefore to prevent food contamination...
