Increased Nitric Oxide Bioavailability and Decreased Sympathetic Modulation Are Involved in Vascular Adjustments Induced by Low-Intensity Resistance Training.

Resistance training is one of the most common kind of exercise used nowadays. Long-term high-intensity resistance training are associated with deleterious effects on vascular adjustments. On the other hand, is unclear whether low-intensity resistance training (LI-RT) is able to induce systemic changes in vascular tone.

[Not Available].

Ehlers-Danlos syndrome is a genetic disease that results in abnormalities of collagen synthesis, causing extremely fragile connective tissue. This fragility predisposes patients to a series of vascular disorders, such as dissections, aneurysms and pseudoaneurysms. The authors describe the case of a 19-year-old patient with an aneurysm of the brachiocephalic trunk who was treated endovascularly by placement of covered stents.

Aortic valve replacement with the Carpentier-Edwards Perimount bioprosthesis: Clinical and hemodynamic evaluation.

Introduction: The number of aortic valve replacement (AVR) surgeries has increased recently, along with the number of bioprosthetic valves implantations. Several studies reported excellent durability and low incidence of valve-related complications with the Carpentier-Edwards Perimount (CEP) pericardial bioprosthesis. The aim of this study is to evaluate the hemodynamic performance and clinical outcomes of the CEP in the aortic position.

Vascular Reconstruction Is Not Warranted in Most Civilian Traumatic Shank Vascular Injuries.

Background: Operative management of traumatic shank vascular injuries (SVI) evolved significantly in the past few decades, thereby leading to a dramatic decrease in amputation rates. However, there is still controversy regarding the minimum number of patent shank arteries sufficient for limb salvage.

Methods: Between January 2006 and September 2011, 191 adult trauma patients presented to an urban level I trauma center in Miami, Florida, with traumatic lower extremity vascular injuries.

Solitary pulmonary nodule and (18)F-FDG PET/CT. Part 2: accuracy, cost-effectiveness, and current recommendations.

A solitary pulmonary nodule is a common, often incidental, radiographic finding. The investigation and differential diagnosis of solitary pulmonary nodules remain complex, because there are overlaps between the characteristics of benign and malignant processes. There are currently many strategies for evaluating solitary pulmonary nodules.

Solitary pulmonary nodule and (18)F-FDG PET/CT. Part 1: epidemiology, morphological evaluation and cancer probability.

Solitary pulmonary nodule corresponds to a common radiographic finding, which is frequently detected incidentally. The investigation of this entity remains complex, since characteristics of benign and malignant processes overlap in the differential diagnosis. Currently, many strategies are available to evaluate solitary pulmonary nodules with the main objective of characterizing benign lesions as best as possible, while avoiding to expose patients to the risks inherent to invasive methods, besides correctly detecting cases of lung cancer so as the potential curative treatment is not delayed.

Polymorphism C242T in the Cyp19 gene in meat sheep.

The objective of this study was to evaluate the frequency of C242T polymorphism on the aromatase gene and the allelic and genotypic frequency of these variants in sheep belonging to four breed groups. Blood samples were collected from 187 animals of four breed groups: Dorper, Santa Inês, Texel and White Dorper, originated from herds in the region of Maringá/PR, Brazil. The genomic DNA was extracted using alkaline extraction, with subsequent amplification of the fragments via PCR with specific primer.

Efficacy of Angiotensin-Converting Enzyme Inhibitors and Angiotensin-Receptor Blockers in Coronary Artery Disease without Heart Failure in the Modern Statin Era: a Meta-Analysis of Randomized-Controlled Trials.

Purpose: Current practice guidelines support the use of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin-receptor blockers (ARBs) in patients with coronary artery disease (CAD) without heart failure (HF). However, a number of cited trials were performed prior to the era of prevalent statin use. Our objective was to evaluate the effectiveness of ACEi and ARBs in reducing cardiovascular events as well as the impact of statin therapy.

Introduction: Acute Aortic Syndrome (AAS) affecting the ascending aorta still represents a challenge to cardiologists and cardiothoracic surgeons, being associated with high mortality even with early surgery.

Aims: To describe the immediate post-operative results and long-term survival after the surgical treatment of type A AAS. Secondary outcomes include hospital mortality, length of hospital stay and long-term mortality.

Relationship between body mass index and mean arterial pressure in normotensive and chronic hypertensive pregnant women: a prospective, longitudinal study.

Background: Being overweight is associated with both higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) during pregnancy and increased risk of gestational hypertensive disorders. The objective of this study was to determine and quantify the effect of body mass index (BMI) on mean arterial pressure (MAP) at several time points throughout pregnancy in normotensive (NT) and chronic hypertensive pregnant (HT) women.

Methods: A prospective longitudinal study was carried out in 461 singleton pregnancies (429 low-risk and 32 with chronic arterial hypertension), with measurements taken at the 1(st), 2(nd), and 3(rd) trimesters and at delivery.

Functionalized nanomaterials: are they effective to perform gene delivery to difficult-to-transfect cells with no cytotoxicity?

Nanodiamonds (NDs), multiwalled carbon nanotubes (MWCNTs) and gold nanorods (NRs) can be functionalized to promote gene delivery to hard-to-transfect cells with higher transfection efficiency than cationic lipids, and inducing less cell death.

Evaluation of clinical and laboratory data for early diagnosis of heparin-induced thrombocytopenia.

Purpose: Results of a study to determine the utility of combining laboratory values and clinical probability scores to improve the detection of heparin-induced thrombocytopenia (HIT) are reported.

Methods: In a retrospective, single-site, chart review-based investigation, 156 cases in which patients with suspected HIT had positive results on a widely used diagnostic test (the anti-heparin/platelet factor 4, or anti-PF4, assay) were identified; in all cases, the blood specimens had been sent to a reference laboratory for confirmation of HIT via serotonin release assay (SRA). After investigator scoring of the clinical probability of HIT in each case by the 4T's method, a multiple logistic regression model was used to evaluate the combined effect of 4T's scores and anti-PF4 assay values in predicting SRA results.

Risks to the fetus from diagnostic imaging during pregnancy: review and proposal of a clinical protocol.

We report a case of genetically confirmed BWS in a 5-month-old girl who presented with a 9.5-cm abdominal mass associated with elevated α-fetoprotein levels.

Incidence of cardiovascular events and gastrointestinal bleeding in patients receiving clopidogrel with and without proton pump inhibitors: an updated meta-analysis.

Background: Dual antiplatelet therapy is the standard of care after coronary stent placement but increases the bleeding risk. The effects of proton pump inhibitors (PPIs) on clopidogrel metabolism have been described, but the clinical significance is not yet definitive. We aimed to do an updated meta-analysis comparing outcomes in patients receiving clopidogrel with and without PPIs.

Wing Morphometry and Acoustic Signals in Sterile and Wild Males: Implications for Mating Success in Ceratitis capitata.

The sterile insect technique (SIT) is widely utilized in the biological control of fruit flies of the family Tephritidae, particularly against the Mediterranean fruit fly. This study investigated the interaction between mating success and morphometric variation in the wings and the production of acoustic signals among three male groups of Ceratitis capitata (Wiedemann): (1) wild males, (2) irradiated with Co-60 (steriles), and (3) irradiated (steriles) and treated with ginger oil. The canonical variate analysis discriminated two groups (males irradiated and males wild), based on the morphological shape of the wings.
