(Diptera: Culicidae) Immune Responses with Different Feeding Regimes Following Infection by the Entomopathogenic Fungus .

The mosquito is the most notorious vector of illness-causing viruses. The use of entomopathogenic fungi as bioinsecticides is a promising alternative for the development of novel mosquito control strategies. We investigate whether differences in immune responses could be responsible for modifications in survival rates of insects following different feeding regimes.

Impaired neurovascular reactivity in the microvasculature of pregnant women with preeclampsia.

Introduction: PE is associated with maternal vascular dysfunction, leading to serious cardiovascular risk both during and following pregnancy.

Objective: To assess microvascular reactivity in pregnant women with PE.

Methods: A cross-sectional study was performed in 36 pregnant women with PE and 36 normotensive pregnant women (C) in the third trimester.

Larvicidal Potential of the Halogenated Sesquiterpene (+)-Obtusol, Isolated from the Alga Laurencia dendroidea J. Agardh (Ceramiales: Rhodomelaceae), against the Dengue Vector Mosquito Aedes aegypti (Linnaeus) (Diptera: Culicidae).

Dengue is considered a serious public health problem in many tropical regions of the world including Brazil. At the moment, there is no viable alternative to reduce dengue infections other than controlling the insect vector, Aedes aegypti Linnaeus. In the continuing search for new sources of chemicals targeted at vector control, natural products are a promising alternative to synthetic pesticides.

Facial responses to basic tastes in the newborns of women with gestational diabetes mellitus.

Objective: To compare facial responses to basic tastes among newborns of women with and without gestational diabetes mellitus (GDM).

Methods: Two-hundred and one healthy newborns, 100 from GDM women were studied at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Brazil.

MR arthrography of the shoulder: optimizing pulse sequence protocols for the evaluation of cartilage and labrum.

Objectives: To compare axial T1weighted fat-saturated (T1w fs) and T1w non-fs sequences, and coronal T1w-fs and T2w-fs sequences, for evaluation of cartilage and labrum using CT arthrography (CTA) as the reference.

Methods: Patients had MR arthrography (MRA) and CTA of the shoulder on the same day. Cartilage was assessed for superficial and full thickness focal and diffuse damage.

Effects of an aquatic physical exercise program on glycemic control and perinatal outcomes of gestational diabetes: study protocol for a randomized controlled trial.

Background: Gestational diabetes mellitus (GDM) is increasing worldwide and has been associated with adverse perinatal outcomes and high risk for chronic disease both for the mother and for the child. Physical exercise is feasible for diabetic pregnant women and contributes to better glycemic control and to a decrease in adverse perinatal outcomes. However, there are no randomized controlled trials (RCT) assessing the effects of aquatic physical exercise on GDM control and adverse maternal and fetal outcomes.

Inorganic polyphosphates regulate hexokinase activity and reactive oxygen species generation in mitochondria of Rhipicephalus (Boophilus) microplus embryo.

The physiological roles of polyphosphates (poly P) recently found in arthropod mitochondria remain obscure. Here, the possible involvement of poly P with reactive oxygen species generation in mitochondria of Rhipicephalus microplus embryos was investigated. Mitochondrial hexokinase and scavenger antioxidant enzymes, such as superoxide dismutase, catalase, and glutathione reductase were assayed during embryogenesis of R.

Glycogen and glucose metabolism are essential for early embryonic development of the red flour beetle Tribolium castaneum.

Control of energy metabolism is an essential process for life. In insects, egg formation (oogenesis) and embryogenesis is dependent on stored molecules deposited by the mother or transcribed later by the zygote. In oviparous insects the egg becomes an isolated system after egg laying with all energy conversion taking place during embryogenesis.

MRI of bone marrow abnormalities in hematological malignancies.

Magnetic resonance imaging (MRI) is essential for evaluating bone marrow. Bone marrow undergoes constant modification and its appearance on MRI changes in response. Knowledge of the types of changes and their origins is essential for analysis of MRI findings of bone marrow infiltration with hematological malignancies.

On the mechanisms involved in biological heme crystallization.

Blood-feeding organisms digest hemoglobin, releasing large quantities of heme inside their digestive tracts. Free heme is very toxic, and these organisms have evolved several mechanisms to protect against its deleterious effects. One of these adaptations is the crystallization of heme into the dark-brown pigment hemozoin (Hz).

Alpha-glucosidase promotes hemozoin formation in a blood-sucking bug: an evolutionary history.

Background: Hematophagous insects digest large amounts of host hemoglobin and release heme inside their guts. In Rhodnius prolixus, hemoglobin-derived heme is detoxified by biomineralization, forming hemozoin (Hz). Recently, the involvement of the R.

[Thymus hyperplasia in a patient with antiphospholipid syndrome].

Thymus is an important central lymphoid organ that plays a pivotal role in the generation of peripheral T-lymphocytes. Thymoma and thymus hyperplasia have been associated with various autoimmune disorders, mainly myasthenia gravis. There is no established relationship between thymus pathology and antiphospholipid syndrome; however, there are some reported cases of antiphospholipid syndrome associated with myasthenia gravis or following thymectomy.

[Idiopathic hypoparathyroidism and systemic lupus erythematosus: a rare association].

A 20-year-old woman was admitted to our hospital after two generalized seizures with severe hypocalcemia. She was diagnosed with Idiopathic Hypoparathyroidism. In the follow-up she was diagnosed with Systemic Lupus Erythematosus (SLE) by the presentation of four criteria of the American College of Rheumatology (ACR) for SLE.

[Lower lung field tuberculosis].

Lower lung lobe tuberculosis is less common than the classical radiological forms of pulmonary tuberculosis. However this radiological presentation has a particular relevance in patients with some associated pathological conditions, such as diabetes mellitus, HIV infection and chronic alcoholism. We make a review of this entity in reference to an illustrative clinical case.

Cardiac sarcoidosis: a case report.

Cardiac involvement is found in approximately 5% of patients with sarcoidosis. The course of the disease is variable, ranging from benign arrhythmias to high-degree heart block or sudden death, and diagnosis is difficult. Endomyocardial biopsy can confirm the diagnosis but the diagnostic yield of the procedure is low because of the uneven distribution of the granulomatous process.

[Mediastinal seminoma: in reference to a case report].

In reference to a clinical report, the authors of this article make a review about semiology, diagnosis and treatment of mediastinal seminoma.

[Endobronchial sarcoidosis: in reference to a clinical report].

In reference to a clinical report, the authors make a review on sarcoidosis and it's endobronchial involvement.

The haemoxisome: a haem-iron containing structure in the Rhodnius prolixus midgut cells.

Rhodnius prolixus midgut was analysed using transmission electron microscopy and electron spectroscopic imaging in order to localize the cellular structures involved in haem metabolism. In the posterior midgut, special cellular electron-dense structures were observed. These structures are here designated haemoxisomes.

Effects of angiotensins on day-night fluctuations and stress-induced changes in blood pressure.

In this study we evaluated by telemetry the effects of ANG II and ANG-(1-7) infusion on the circadian rhythms of blood pressure (BP) and heart rate (HR) and on the cardiovascular adjustment resulting from restraint stress in rats. ANG II or ANG-(1-7) or vehicle were infused subcutaneously for 7 days. Restraint stress was carried out before, during, and after infusion at 7-day intervals.
