In the present study, we investigate whether methylphenidate (MPH) affects emotional processing and whether this effect is modulated by age. We measured amygdala reactivity with functional Magnetic Resonance Imaging (fMRI) during processing of angry and fearful facial expressions in male stimulant treatment-naive patients with ADHD (N = 35 boys; N = 46 men) and 23 healthy control subjects (N = 11 boys; N = 12 men). In ADHD patients, we also measured amygdala reactivity 90min after an acute oral challenge with MPH (0...

The mechanism of action of psychostimulant drugs in the treatment of Attention Deficit Hyperactivity Disorder is still largely unknown, although recent evidence suggests one possibility is that the drugs affect the superior colliculus (SC). We have previously demonstrated that systemically administered d-amphetamine attenuates/abolishes visual responses to wholefield light flashes in the superficial layers of the SC in anaesthetised rats, and the present study sought to extend this work to methylphenidate (MPH)...

The ventrobasal (VB) thalamus relay nucleus processes information from rodents' whiskers, projecting to somatosensory cortex. Cocaine and methylphenidate (MPH) have been described to differentially alter intrinsic properties of, and spontaneous GABAergic input to, VB neurons. Here we studied using bis-fura 2 ratiometric fluorescence the effects of cocaine and MPH on intracellular [Ca(2+)] dynamics at the soma and dendrites of VB neurons. Cocaine increased baseline fluorescence in VB somatic and dendritic compartments...

Azithromycin (AZM) is a clinically important antibiotic to Vibrio cholerae especially for inhibiting colonization of V. cholerae in intestine and the treatment of severe cholera in children and pregnant women. One IncA/C plasmid was isolated from both of the high MIC AZM resistant V cholerae strains of the two mainly pathogenic serogroups, O1 and O139. In the 172 predicted ORFs, 16 genes were related to antibiotic resistance in which 5 were well-defined genes associated with macrolide resistance. The 5 macrolide resistant genes disturbed in two clusters, mphR-mrx-mph(K) and mel-mph2, flanking by insertion sequence (IS) and involving two kinds of mechanisms...

Pistacia vera seed is a common food and medicinal seed in Iran. It's hull (outer skin) as a significant byproduct of pistachio, is traditionally used as tonic, sedative and antidiarrheal and has been shown to be a rich source of antioxidants. The aim of the present study is to evaluate the anti-melanogenic activity of the pistachio hulls in order to discover a new alternative herbal agent to treat skin hyperpigmentation disorders. In this work, antioxidant and anti-tyrosinase activity of MeOH extract from Pistacia vera hull (MPH) were evaluated in vitro, respectively, by DPPH radical scavenging and mushroom tyrosinase activity assays...

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in which a significant proportion of patients do not respond to treatment. The objective of this study was to examine the role of genetic risk variants in the response to treatment with methylphenidate (MPH). The effectiveness of MPH was evaluated based on variations in the CGI-S and CGAS scales over a 12-month treatment period using linear mixed effects models. A total of 208 ADHD patients and 34 polymorphisms were included in the analysis...

Insufficient suppression and connectivity of the default mode network (DMN) is a potential mediator of cognitive dysfunctions across various disorders, including attention deficit/hyperactivity disorder (ADHD). However, it remains unclear if alterations in sustained DMN suppression, variability and connectivity during prolonged cognitive engagement are implicated in adult ADHD pathophysiology, and to which degree methylphenidate (MPH) remediates any DMN abnormalities. This randomized, double-blinded, placebo-controlled, cross-over clinical trial of MPH (clinicaltrials...

This work presents ultrasound-assisted dispersive micro solid phase extraction (USA DMSPE) for preconcentration of fluorine (F) in water and herb samples. TiO2 nanoparticles (NPs) were used as an adsorbent. The determination with slurry sampling was performed via molecular absorption of calcium monofluoride (CaF) at 606.440 nm using a high-resolution continuum source electrothermal absorption spectrometry (HR-CS ET MAS). Several factors influencing the efficiency of the preconcentration technique, such as the amount of TiO2, pH of sample solution, ultrasonication and centrifugation time and TiO2 slurry solution preparation before injection to HR-CS ET MAS, were investigated in detail...

BACKGROUND/AIMS: Although microangiopathic hemolysis (MAH) is a well-known complication of malignant phase hypertension (MPH), only less data on whether MAH in MPH predicts renal outcome exist. Therefore, we evaluated whether MAH was associated with the renal outcome in patients with MPH. METHODS: We conducted a single-center, retrospective, cohort study. Data from 35 patients diagnosed with MPH between October 1998 and January 2015 were analyzed. MPH was defined as the presence of a diastolic blood pressure of ≥120 mm Hg and grades III/IV hypertensive retinopathy according to the Keith-Wagener-Barker classification...

BACKGROUND/PURPOSE: Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) are frequently co-occurring in youth, but data about the pharmacological management of this comorbidity are scarce, especially when impulsive aggression is prominent. Although stimulants are the first-line medication for ADHD, second-generation antipsychotics, namely, risperidone, are frequently used. We aimed to assess effectiveness and safety of monotherapy with the stimulant methylphenidate (MPH) and risperidone in a consecutive sample of 40 drug-naive male youths diagnosed as having ADHD-combined presentation, comorbid with ODD and aggression, without psychiatric comorbidities, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria and a structured clinical interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version)...
