Urinary dedifferentiated podocytes as a non-invasive biomarker of lupus nephritis.

Background: Currently, renal biopsy remains the gold standard for the diagnosis and prognosis of lupus nephritis (LN). However, it is an invasive method, and new non-invasive laboratory tests are needed to identify renal involvement without renal biopsy. Podocyte damage plays an important role in the pathogenesis and progression of systemic lupus erythematosus (SLE).

Microbiological methods for surveillance of carrier status of multiresistant bacteria.

The presence of colonised patients is one of the main routes for the spread of multiresistant bacteria, and its containment is a clinical and public health priority. Surveillance studies are essential for early detection of colonisation by these bacteria. This article discusses the different microbiological methods, both based on culturing and molecular methods, for detection of carriers of multiresistant bacteria.

The goal of this study was to evaluate the efficacy, in vitro, of 11 essential oils from Brazil on reproductive efficiency and lethality of the cattle tick Rhipicephalus (Boophilus) microplus. The effects of oils extracted from Curcuma longa, Zingiber officinale, Lippia alba, Lippia gracilis, Lippia origanoides, Lippia sidoides, Mentha arvensis, Mentha piperita, Croton cajucara (white and red), and Croton sacaquinha on ticks were investigated by the Immersion Test with Engorged Females (ITEF) and the modified Larval Packet Test (LPT).

Immunohistochemical Evaluation of Glucose Transporter Type 1 in Epithelial Dysplasia and Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and some of these have been documented in association or preceded by oral epithelial dysplasia (OED). Aggressive cancers with fast growth have demonstrated overexpression of some glucose transporters (GLUTs). Thus, the aim of this study was to analyze the immunohistochemical expression of the glucose transporter, GLUT-1, in OEDs and OSCCs, seeking to better elucidate the biological behavior of neoplasias.

Postprandial Changes in Chemokines Related to Early Atherosclerotic Processes in Familial Hypercholesterolemic Subjects: A Preliminary Study.

Background And Aims: Familial hypercholesterolemia (FH) is associated with higher levels of inflammatory mediators such as chemokines, which contribute to an increased risk of premature atherosclerosis in these patients. We studied the response of chemokines related to early atherosclerotic processes during an oral unsaturated fat load test (OFLT) in patients with heterozygous FH and compared this response to normolipidemic and normoglycemic subjects.

Methods: Blood samples were taken from 12 FH patients and 20 healthy controls with a similar age, gender distribution, and body mass index.

Transcriptional regulatory networks controlling woolliness in peach in response to preharvest gibberellin application and cold storage.

Background: Postharvest fruit conservation relies on low temperatures and manipulations of hormone metabolism to maintain sensory properties. Peaches are susceptible to chilling injuries, such as 'woolliness' that is caused by juice loss leading to a 'wooly' fruit texture. Application of gibberellic acid at the initial stages of pit hardening impairs woolliness incidence, however the mechanisms controlling the response remain unknown.

Diffuse Gastric Cancer During Pregnancy: Report of a Rare Association.

Gastric cancer during pregnancy is a rare event and difficult to diagnose, as the symptoms can be confused with those of an ordinary pregnancy. We report a case of a 25-year-old patient with a 29-week gestation, with asthenia complaint, vomiting and weight loss. During the investigation of wasting syndrome endoscopy was performed with infiltrative ulcerative lesions in pre-pyloric region with biopsy revealing carcinoma with signet ring, undifferentiated type.

Increased Urinary Exosomal MicroRNAs in Patients with Systemic Lupus Erythematosus.

There is increased interest in using microRNAs (miRNAs) as biomarkers in different diseases. Present in body fluids, it is controversial whether or not they are mainly enclosed in exosomes, thus we studied if urinary miRNAs are concentrated inside exosomes and if the presence of systemic lupus erythematosus with or without lupus nephritis modifies their distribution pattern. We quantified specific miRNAs in urine of patients with systemic lupus erythematosus (n = 38) and healthy controls (n = 12) by quantitative reverse-transcription PCR in cell-free urine, exosome-depleted supernatant and exosome pellet obtained by ultracentrifugation.

The nutrigenetic influence of the interaction between dietary vitamin E and TXN and COMT gene polymorphisms on waist circumference: a case control study.

Background: Abdominal obesity (AO) is a common modifiable risk factor for certain non-communicable diseases associated with enhanced oxidative stress (OS). The objective of this work was to investigate whether the interaction between antioxidant vitamin intake and OS-related polymorphisms modulates gene-associated anthropometry in a Spanish population.

Methods: A total of 246 subjects with AO, and 492 age and gender matched non-AO subjects were included in the study.

Characterization of microsatellite markers for the Restinga Antwren, Formicivora littoralis (Thamnophilidae), an endangered bird endemic to Brazil.

Molecular markers are important tools in determining parentage, gene flow, and the genetic structure of species. In the case of rare, endemic, and/or threatened species, these markers can be used to understand key ecological questions and support conservation actions. We developed seven microsatellite markers for the only bird endemic to the Restinga ecosystem.
