An additional chromatographic peak was observed in plasma samples of patients receiving NX 211, a liposomal formulation of the topoisomerase I inhibitor lurtotecan. We have isolated and purified this product by sequential solid-phase extractions, and we report its structure and cytotoxicity relative to lurtotecan and related agents. Nuclear magnetic resonance data indicate that cleavage of the ...

OBJECTIVES Establishing indirect immunofluorescence (IFAT) and enzyme-inked immunoassay (ELISA) serological tests' ability to detect canine visceral leishmaniasis (CVL) infection. METHODS 211 cross-bred dogs from the south of the Tolima department (a visceral leishmaniasis endemic area) were evaluated by clinical and serological exams, using the Colombian Leishmania infantum (infantum) MHOM/C...

INTRODUCTION: The occurrence of leprosy reactions, a common event during treatment, may be mostly related to the action of multidrug therapy on Mycobacterium leprae. The clinical and laboratory monitoring of patients with reactions is important, since collecting data that assists in predicting the risk of reactions may help to prevent disability. METHODS: This was a sectional study, in orde...

BACKGROUND A clear association of amino acid variation in the prion protein gene (PRNP) with susceptibility and resistance to classical scrapie exists in sheep, but not in goats. In this study we examined DNA sequence variation in the PRNP of 149 animals from two scrapie-infected herds of Saanen dairy goats, and identified 6 non-synonymous variants in the coding region. RESULTS In the larger ...

LP-211 is a new, selective agonist of serotonin (5-hydroxytryptamine, 5-HT) receptor 7 (5-HT7-R), which is part of a neuro-transmission system with a proposed role in neural plasticity and in mood, cognitive and sleep regulation. Adolescent subchronic LP-211 treatment produces some persisting changes in rats' forebrain structural and functional parameters. Here, using pharmacological MRI (phMRI...

Chronic allograft dysfunction (CAD) remains the major cause of renal transplant loss and characterized by interstitial fibrosis and tubular atrophy (IFTA). MicroRNAs (miRNAs) are implicated in many biological processes as well as innate and adaptive immune responses. We aimed to investigate whether CAD with IFTA is associated with differential expression of miR-142-5p, miR-142-3p and miR-211 wi...

Flexibility and efficiency of coding, content extraction, and content-based search are key research topics in the field of interactive multimedia. Ongoing ISO MPEG-4 and MPEG-7 activities are targeting standardization to facilitate such services. European COST Telecommunications activities provide a framework for research collaboration. COST 211 and COST 211 activities have been instrumental in...

BACKGROUND detention in the harsh conditions of police cells can be a traumatic experience, even for young healthy individuals. It is thus legitimate to question the detention of elderly people. OBJECTIVE we aimed to determine the proportion of detainees over age 60, their medical characteristics and history. METHODS we studied all arrestees over age 60 examined in 1 year (1st January-31 De...

We have used primarily temperature-programmed desorption (TPD) and infrared reflection-absorption spectroscopy (IRAS) to investigate CO adsorption on a Au(211) stepped single-crystal surface. The Au(211) surface can be described as a step-terrace structure consisting of three-atom-wide terraces of (111) orientation and a monatomic step with a (100) orientation, or 3(111) x (100) in microfacet n...
