In this paper first the Multi-term Fractional-Order PID (MFOPID) whose transfer function is equal to [Formula: see text] , where kj and αj are unknown and known real parameters respectively, is introduced. Without any loss of generality, a special form of MFOPID with transfer function kp+ki/s+kd1s+kd2s(μ) where kp, ki, kd1, and kd2 are unknown real and μ is a known positive real parameter, is considered. Similar to PID and TID, MFOPID is also linear in its parameters which makes it possible to study all of them in a same framework...

The propensity for cytochrome P450 (CYP)3A4 induction by 2-(6-(5-chloro-2-methoxyphenyl)-4-oxo-2-thioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide (PF-06282999), an irreversible inactivator of myeloperoxidase, was examined in the present work. Studies using human hepatocytes revealed moderate increases in CYP3A4 messenger RNA (mRNA) and midazolam-1'-hydroxylase activity in a PF-06282999 dose-dependent fashion. At the highest tested concentration of 300 μM, PF-06282999 caused maximal induction in CYP3A4 mRNA and enzyme activity ranging from 56% - 86% and 47% - 72%, respectively, of rifampicin response across the three hepatocyte donor pools...

Polychlorinated biphenyls (PCBs) are a group of synthetic chlorinated compounds that have been widely used as dielectric fluids in capacitors and transformers. Due to their toxicity, persistence, and bioaccumulation in the food chain, PCBs are an environmental concern and among the most analyzed compounds in environmental analysis. The most common analytical methods for analysis of PCBs are based on gas chromatography-electron capture detection (GC-ECD) and gas chromatography-mass spectrometry (GC-MS). However, the number of possible congeners (209), similarities of physical and chemical properties, and complexity of sample matrices make it difficult to distinguish and accurately speciate PCB congeners using existing methods...

BACKGROUND: In a previous study, 6-minute walk distance (6MWD) improvement with sildenafil was not dose dependent at the 3 doses tested (20, 40, and 80 mg 3 times daily [TID]). This study assessed whether lower doses were less effective than the approved 20-mg TID dosage. METHODS: Treatment-naive patients with pulmonary arterial hypertension were randomized to 12 weeks of double-blind sildenafil 1, 5, or 20 mg TID; 12 weeks of open-label sildenafil 20 mg TID followed...

Interstitial pneumonitis is a classical complication of many drugs. Pulmonary toxicity due to 5-azacytidine, a deoxyribonucleic acid methyltransferase inhibitor and cytotoxic drug, has rarely been reported. We report a 67-year-old female myelodysplastic syndrome patient treated with 5-azacytidine at the conventional dosage of 75 mg/m(2) for 7 days. One week after starting she developed moderate fever along with dry cough and subsequently her temperature rose to 39.5 °C. She was placed under broad-spectrum antibiotics based on the protocol for febrile neutropenia, including ciprofloxacin 750 mg twice daily, ceftazidime 1 g three times daily (tid), and sulfamethoxazole/trimethoprim 400 mg/80 mg tid...

Increasingly complex demonstrations of integrated circuit elements based on semiconducting single-walled carbon nanotubes (SWCNTs) mark the maturation of this technology for use in next-generation electronics. In particular, organic materials have recently been leveraged as dopant and encapsulation layers to enable stable SWCNT-based rail-to-rail, low-power complementary metal-oxide-semiconductor (CMOS) logic circuits. To explore the limits of this technology in extreme environments, here we study total ionizing dose (TID) effects in enhancement-mode SWCNT-CMOS inverters that employ organic doping and encapsulation layers...

BACKGROUND: Helicobacter pylori eradication rates in Portugal are declining, due to increased resistance of this bacterium to antimicrobial agents, especially Clarithromycin. Quadruple Levofloxacin-containing regimens could be an option for first-line treatment, but its efficacy should be evaluated as fluoroquinolone resistance is rapidly increasing. Our aim was to compare the efficacy of Clarithromycin and Levofloxacin-based sequential quadruple therapies as first-line treatment options and determine factors associated with treatment failure...

Low-dose SoluMatrix diclofenac was developed to provide effective pain relief for osteoarthritis pain. We evaluated the effects of SoluMatrix diclofenac on health-related quality of life (HRQoL) measures in patients with osteoarthritis, hypothesizing that SoluMatrix-treated patients would experience significant improvement compared with placebo. In this 12-week, phase 3 randomized controlled trial, 305 patients with osteoarthritis of the hip or knee received SoluMatrix diclofenac 35 mg three times (TID) or twice (BID) daily or placebo...

BACKGROUND: Delayed-release dimethyl fumarate (DMF) is an approved oral treatment for relapsing forms of multiple sclerosis (MS). Preclinical studies demonstrated that DMF activated the nuclear factor E2-related factor 2 (Nrf2) pathway. DMF and its primary metabolite monomethyl fumarate (MMF) were also shown to promote cytoprotection of cultured central nervous system (CNS) cells via the Nrf2 pathway. OBJECTIVE: To investigate the activation of Nrf2 pathway following ex vivo stimulation of human peripheral blood mononuclear cells (PBMCs) with DMF or MMF, and in DMF-treated patients from two Phase 3 relapsing MS studies DEFINE and CONFIRM...

Visual system pathway dysfunction has been postulated in migraineurs. We wanted to investigate if any difference exists interictally in visual attention and visual evoked habituation of frequently attacked migraineurs compared to the healthy control group. The effects of 3-month prophylactic migraine treatment on these parameters were also assessed. The migraineurs at headache-free interval (n = 52) and age, sex-matched healthy controls (n = 35) were compared by habituation response to 10 blocks of repetitive pattern-reversal visual stimuli (each block consisted 100 responses)...

After dipyridamole infusion, electrocardiographic (ECG), blood pressure and heart rate (HR) changes were seen. We tried to investigate whether there is a relationship between hemodynamic, ECG and HR changes after dipyridamole infusion and gated myocardial perfusion SPECT findings. We studied 206 consecutive patients which underwent a 2-day protocol Dipyridamole Stress/Rest Tc99m-Sestamibi gated myocardial perfusion SPECT. Systolic blood pressure (SBP), diastolic blood pressure (DBP), HR and ECG were recorded...

The aim of this analysis was to examine sex-based differences in renal segmental resistances in healthy controls (HC) and patients with type 1 diabetes (T1D). We hypothesized that hyperfiltration - an early hemodynamic abnormality associated with diabetic nephropathy (DN) - would disproportionately affect women with T1D, thereby attenuating protection against the development of renal complications. Glomerular hemodynamic parameters were evaluated in HC (n=30) and in normotensive, normoalbuminuric patients with T1D and either baseline normofiltration (n=36, T1D-N, glomerular filtration rate [GFR] 90-134 ml/min/1...

INTRODUCTION: Pharmacokinetic of vancomycin in very low birth weight neonates showed big variety, and limited data were available due to very minor population. These facts make it difficult to adjust its optimal initial dosage. Therefore, this study was to develop optimal dosing regimen of vancomycin in very low birth weight neonates. METHODS: Between 2010 and 2015, low birth weight neonates (≤1500 g) were included in a population pharmacokinetics analysis. Based on the pharmacokinetic parameters we estimated, we simulated individual blood concentrations of vancomycin and evaluated the probability of its pharmacokinetics/pharmacodynamics (PK/PD) target attainment, such as 24-h area under the concentration-time curve (AUC24)/MIC (≥400) and blood trough concentration (10-20 μg/mL), as primary measure for several dosing regimens by Monte Carlo simulation method...

Supraventricular tachycardia (SVT) is a common infant arrhythmia, for which beta-blockers are frequently chosen as therapy. Propranolol is a common choice though it is dosed every 6-8 h. We reviewed the clinical results of treating infant SVT with an extemporaneous preparation of nadolol. Retrospective cohort study of patients under 2 years old receiving nadolol for SVT at a single center. Patients were ascertained by patient and pharmacy databases. Twenty-eight infants received nadolol, of whom 25 had regular narrow complex tachycardia, 2 atrial flutter, and 1 focal atrial tachycardia...

WHAT IS KNOWN AND OBJECTIVE: Previous studies indicate that the implementation of a prior authorization requirement for coxibs was followed by a sharp decline in their use. There are no studies showing what happens if coxib prior authorization is removed. The objective of this study is to assess the trend in the use of coxibs marketed in Spain, following removal of their respective prior authorization requirements in November 2006 for celecoxib and February 2007 for etoricoxib. METHODS: We calculated the monthly number of defined daily doses per thousand inhabitants per day (DDD/TID) of coxibs dispensed in a health area of Spain from mid-2005 to December 2007...
