Leishmania (V.) braziliensis and Leishmania(L.) amazonensis are the most pathogenic agents of American Cutaneous Leishmaniasis in Brazil, causing a wide spectrum of clinical and immunopathological manifestations, including: localized cutaneous leishmaniasis (LCLDTH+/++), borderline disseminated cutaneous leishmaniasis (BDCLDTH±), anergic diffuse cutaneous leishmaniasis (ADCLDTH-), and mucosal leishmaniasis (MLDTH++++). It has recently been demonstrated, however, that while L. (V.) braziliensis shows a clear potential to advance the infection from central LCL (a moderate T-cell hypersensitivity form) towards ML (the highest T-cell hypersensitivity pole), L...

Frontal EEG asymmetry (FEA) has been studied as both state and trait parameter in emotion regulation and affective disorders. Its significance in borderline personality disorder (BPD) remains largely unknown. Twenty-six BPD patients and 26 healthy controls underwent EEG before and after mood induction using aversive images. A slight but significant shift from left- to right-sided asymmetry over prefrontal electrodes occurred across all subjects. In BPD baseline FEA over F7 and F8 correlated significantly with childhood trauma and functional neurological "conversion" symptoms as assessed by respective questionnaires...

Borderline personality disorder (BPD) and chronic depression (CD) are common and challenging mental disorders. Maladaptive cognitive schemas have been proposed to increase vulnerability to both disorders. In order to elucidate the role of maladaptive cognitive schemas in BPD and CD, this study compared psychiatric outpatients with BPD (N = 30) and CD (N = 30) in terms of early maladaptive schemas (EMSs). The groups were compared using the Young Schema Questionnaire short form-extended (YSQ-S2-extended) and the 15D health status questionnaire...

One of the core symptoms of borderline personality disorder (BPD) is emotion dysregulation, which comprises emotion sensitivity, heightened and labile negative affect, deficient appropriate regulation strategies, and a surplus of maladaptive regulation strategies. Although earlier studies provided some evidence for threat hypersensitivity in terms of a negatively biased perception of other people ("negativity bias") and deficits in the recognition of full-blown anger, i.e., higher error rates and slower reaction times, researchers have only recently started studying effects of interindividual differences (e...

Short-term moderate doses of serotonergic and dissociative hallucinogens can be useful in the treatment of anxiety. Recently, a trend has developed for long-term intermittent 'microdosing' (usually one-tenth of a 'full' active dose), with reports of long-lasting relief from anxiety and related disorders; however, there is no scientific evidence for the efficacy of therapeutic microdosing nor to show its lasting effects. The objective of this study was to test for lasting effects on anxiety in rats after microdosing with ketamine or psilocin...

PURPOSE: The WEE1 tyrosine kinase regulates G2/M transition and maintains genomic stability, particularly in p53-deficient tumors which require DNA repair after genotoxic therapy. There is a need to exploit the role of WEE1 inhibition in head and neck squamous cell carcinoma (HNSCC) mostly driven by tumor-suppressor loss. This completed phase I clinical trial represents the first published clinical experience using the WEE1 inhibitor, AZD1775, with cisplatin and docetaxel. EXPERIMENTAL DESIGN: We implemented an open-label phase I clinical trial using a 3+3 dose-escalation design for patients with Stage III/IVB HNSCC with borderline-resectable or unresectable disease, who were candidates for definitive chemoradiation...

BACKGROUND: One indication for intervention in coarctation of the aorta is a peak-to-peak gradient >20 mmHg. Gradients may be masked in patients under general anaesthesia and may be higher during exercise. Isoproterenol was given during cardiac catheterisation to simulate a more active physiologic state. OBJECTIVES: We aimed to describe the haemodynamic effects of isoproterenol in patients with coarctation and the impact of intervention on the elicited gradients...

Primary myelofibrosis (PMF) is a chronic clonal myeloid disorder. Together with essential thrombocythemia (ET) and polycythemia vera (PV), it belongs to a group of Philadelphia chromosome-negative myeloproliferative neoplasms. An integral part of laboratory tests carried out in this disease group is detecting the presence of mutations in the Janus kinase 2 gene at position 617 (JAK2 V617F) and in the gene encoding for the receptor for thrombopoietin (myeloproliferative leukemia virus oncogene, MPL) found in approximately 60% of PMF patients...

24-hour esophageal pH-metry is not designed to detect laryngopharyngeal reflux (LPR). The new laryngopharyngeal pH-monitoring system (Restech) may detect LPR better. There is no established correlation between these two techniques as only small case series exist. The aim of this study is to examine the correlation between the two techniques with a large patient cohort. All patients received a complete diagnostic workup for gastroesophageal reflux including symptom evaluation, endoscopy, 24-hour pH-metry, high resolution manometry, and Restech...

Traditionally, validation was considered to be a final gatekeeping function, but refinement is smoother and results are better if model validation actively guides corrections throughout structure solution. This shifts emphasis from global to local measures: primarily geometry, conformations and sterics. A fit into the wrong local minimum conformation usually produces outliers in multiple measures. Moving to the right local minimum should be prioritized, rather than small shifts across arbitrary borderlines...

For the purpose of this article, experimental phasing is understood to mean the determination of macromolecular structures by exploiting small intensity differences of Friedel opposites and possibly of reflections measured at different wavelengths or for heavy-atom derivatives, without the use of specific structural models. The SHELX programs provide a robust and efficient route for routine structure solution by the SAD, MAD and related methods, but involve a number of simplifying assumptions that may limit their applicability in borderline cases...

The aim of the present study is to contribute to the scientific characterization of sildenafil citrate according to the Biopharmaceutics Classification System, following the World Health Organization (WHO) guidelines for biowaivers. The solubility and intestinal permeability data of sildenafil citrate were collected from literature; however, the experimental solubility studies are inconclusive and its "high permeability" suggests an API in the borderline of BCS Class I and Class II. The pH-solubility profile was determined using the saturation shake-flask method over the pH range of 1...

Introduction: Physician global assessments of disease activity (medical doctor (MD) globals) are important outcomes. MD globals may vary based on their age, gender, practice setting and experience (number of patients seen per year and years in practice). Methods: We determined the variability of MD globals, surveying rheumatologists from the Canadian Rheumatology Association using rheumatoid arthiritis (RA) cases rated by MD for disease activity from 0 to 10. Cases were developed to span the spectrum of disease activity...

Oxidative stress has been implicated in the development of hypertension, arterial stiffness and atherosclerosis. Optimal functioning of the enzymatic antioxidant system is central to prevent increased oxidative stress and its consequences. We aimed to investigate the relationships of ambulatory blood pressure and carotid intima-media thickness with enzyme activities of the glutathione cycle in 396 young, black and white South Africans of the African-PREDICT study. Ambulatory blood pressure and carotid intima-media thickness were measured and glutathione peroxidase and glutathione reductase activities were analyzed...

The current research tested whether four dimensions of mindfulness - acceptance without judgment, observing, describing and acting with awareness - predicted frequency of nonsuicidal self-injury (NSSI) and mediate the relationship with NSSI outcomes during 20-weeks of Dialectical Behaviour Therapy (DBT) skills training for borderline personality disorder (BPD). Eighty-four self-harming individuals with BPD were randomized to either DBT skills training or to a waitlist control group. A series of regressions revealed no relationship between dimensions of mindfulness and NSSI at baseline...

Borderline personality disorder (BPD) is often a complicating comorbid factor in alcohol use disorders and substance use disorders. Previous work showed that abstinent alcoholics endorsed lifetime and current symptoms of most of the BPD criteria at much higher rates than controls, with much higher symptom counts for short-term abstinent alcoholic (STAA) women than men, which is consistent with such symptoms negatively affecting female alcoholics' ability to maintain abstinence. Because prior work has also shown that treatment-naïve alcoholics (TNA) are not the same as treated alcoholics observed earlier in their alcohol dependence, but rather are a different population with potentially lower psychiatric comorbidity, in this study we compared BPD symptom criteria between TNA samples of comparable age to the control and STAA samples, including both men and women and individuals dependent on alcohol only or with lifetime dependence on both alcohol and drugs...

OBJECTIVES: Effectiveness of the condensed Dialectical Behavior Therapy Skills Training Group (DBTSTG) was compared to the Cognitive Therapy Group (CTG) in reducing depression and suicide reattempt, and modifying emotion regulation strategies among those with borderline personality disorder (BPD). METHODS: Eighty-two depressed BPD college students with a suicidal history within the past six-months were randomly allocated to DBTSTG or CTG. RESULTS: Both groups had similar reductions in suicide reattempts and depression after the intervention and 6-month follow-ups...
