While plants of the genus Dyssodia are used by man to a certain extent, few phytochemical and pharmacological studies have been performed with species of this genus. D. tagetiflora is an endemic plant of Mexico and has been used as fodder. The aim of this research was to isolate and identify the main bioactive components and evaluate the insecticidal, antioxidant, genotoxic and cytoprotective activities of D. tagetiflora. The isolated substances included an essential oil composed of six monoterpenes, and extracts containing two flavonols, three flavonol-glycosides and four thiophenes...

Papillary ibroelastomas are small benign intracardiac tumors known for their embolic potential. Since the introduction of echocardiography with improved resolution and transesophageal imaging techniques, they are being increasingly detected in clinical practice. In recent series, papillary fibroelastoma is considered the most frequent benign tumor of the heart. Our objective was to analyze characteristics and midterm surgical outcome of histologically-confirmed cases of papillary fibroelastoma. We conducted a retrospective study on patients with cardiac tumors submitted to surgical excision between June 1992 and February 2017...

In the follow-up of patients with the clinically isolated syndrome, both clinical and MRI findings should be carefully evaluated by clinicians to avoid misinterpretation and inappropriate diagnosis of multiple sclerosis. We describe a case of a patient with a previous diagnosis of clinically isolated syndrome who developed a new asymptomatic brain lesion at the MRI follow-up. The careful evaluation of clinical history and radiological findings allowed the correct diagnosis of cocaine-associated ischemic stroke...

Amnestic Alzheimer's disease (AD) is characterized by early atrophy of the hippocampus and medial temporal lobes before spreading to the neocortex. In contrast, nonamnestic Alzheimer's patients have relative sparing of the hippocampus, but the pattern in which the disease spreads is unclear. We examined spreading disease in nonamnestic AD using a novel magnetic resonance imaging-based analysis adapted from pathologic staging studies, applied here to cross-sectional imaging data. We selected 240 T1-weighted scans from 129 patients with pathology confirmed by autopsy or cerebrospinal fluid, and atrophy maps were computed relative to 238 scans from 115 elderly controls...

BACKGROUND: Despite the availability of a safe and efficacious vaccine against HPV, uptake of the vaccine in the United States is low. Missed clinical opportunities to recommend and to administer HPV vaccine are considered one of the most important reasons for its low uptake in adolescents, however, little is known about the frequency or characteristics of missed opportunities in the young adult (18-26 years of age) population. OBJECTIVES: To assess both the rates of and the factors associated with missed opportunities for HPV immunization among young adult women who attended an urban obstetrics and gynecology clinic...

Theileria equi is one of the etiologic agents of the equine piroplasmosis. This infectious disease is transmitted by ticks and is a worldwide problem in the international horse movement. The 18S rRNA gene of T. equi is often used for genotyping and phylogenetic purpose. This study aimed to analyze the degree of the heterogeneity of the 18S rRNA gene of T. equi in horses from the state of Rio de Janeiro, Brazil. The complete T. equi 18S rRNA sequences were obtained from twenty naturally infected horses. The PCR amplicons were cloned and sequenced...

BACKGROUND: Despite the ubiquitous use of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in older adults, little is known about the multimorbidity (MM) profile of this patient population. This study evaluates the temporal trends of MM, hypothesizing that patients with MM have had an increasingly greater representation in THA and TKA patients over time. METHODS: Data on a US representative sample of older adults from the linked Health and Retirement Study and Medicare data from 1993 to 2012 were used...

BACKGROUND: Bipolar disorder (BD) is a major psychiatric illness characterized by heterogeneous symptoms including psychotic features. Up until now, neuroimaging studies investigating cerebral morphology in patients with BD have underestimated the potential impact of psychosis on brain anatomy in BD patients. In this regard, psychotic and non-psychotic BD may represent biologically different subtypes of the disorder, being possibly associated with specific cerebral features. METHODS: In the present study, magnetic resonance imaging (MRI) at 3T was used to identify the neuroanatomical correlates of psychosis in an International sample of BD patients...

INTRODUCTION: Some studies indicate high prevalences of latent tuberculosis infection (LTBI) in the immigrant population, which is relevant because 5-10% of cases will develop active tuberculosis. The objective of this study is to describe the results of a sequential strategy in the newly-arrived immigrant population for the diagnosis of LTBI using the tuberculin skin test (TST) and IGRAs. METHODS: A retrospective descriptive study was carried out with immigrants between 6 and 35years of age from shelters, referred to an international health unit between July 2013 and June 2016...

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is used extensively in cardiothoracic surgery both for hemodynamic and respiratory support. It has proven to be a valuable tool to maintain adequate oxygenation during tracheal surgery. Airway lesion may be an indication for veno-venous ECMO both in case of conservative management and in case of surgical repair. Here we report the case of a patient with a iatrogenic tracheal injury, successfully operated with the support of veno-venous extracorporeal oxygenation...

Here we describe a culture technique of cells dissociated from the external muscularis of the guinea pig small intestine, which allows us to maintain all the elements involved in the intestinal peristaltic reflex. After a few days in culture, these cells reorganize to form a small group of cells that permit the generation of pacemaker activity, spontaneous contractions, and the development of inhibitory and excitatory junction potentials in the petri dish, all elements involved in the peristaltic reflex. Therefore, these co-cultures are suitable to study the cellular and molecular aspects related to the development, maintenance, and modulation of motor intestinal functions...
