Some Physiological Effects of Nanofertilizers on Wheat-Aphid Interactions.

The increasing use of nanofertilizers in modern agriculture and their impact on crop yield and pest management require further research. In this study, the effects of nano-Fe, -Zn, and -Cu (which are synthesized based on nanochelating technology), and urea (N) fertilizers on the antioxidant activities of wheat plants (cv. Chamran), and the wheat green aphid (Rondani) are investigated.

Photocage-initiated time-resolved solution X-ray scattering investigation of protein dimerization.

This work demonstrates a new method for investigating time-resolved structural changes in protein conformation and oligomerization photocage-initiated time-resolved X-ray solution scattering by observing the ATP-driven dimerization of the MsbA nucleotide-binding domain. Photocaged small molecules allow the observation of single-turnover reactions of non-naturally photoactivatable proteins. The kinetics of the reaction can be derived from changes in X-ray scattering associated with ATP-binding and subsequent dimerization.

Group Psychotherapy in Italy.

This article describes the history and the prevailing orientations of group psychotherapy in Italy (psychoanalytically oriented, psychodrama, CBT groups) and particularly group analysis. Provided free of charge by the Italian health system, group psychotherapy is growing, but its expansion is patchy. The main pathways of Italian training in the different group psychotherapy orientations are also presented.

An uncommon presentation of eosinophilic granulomatosis with polyangiitis: a case report.

Introduction: Eosinophilic granulomatosis with polyangiitis is a rare and potentially fatal disease if not readily diagnosed. Cerebral involvement is extremely rare and clinical presentation as hemorrhagic stroke is even rarer.

Case Presentation: A 58-year-old Caucasian man was admitted to our medical unit because of a computed tomography-diagnosed hemorrhagic stroke with right-sided hemiparesis and fever.

Prognostic role of aldosterone in patients with acute coronary syndrome: short and medium term follow-up.

Aims: Different studies have shown a correlation between aldosterone, atherosclerosis and ischemia in the past decade. Evidence exists for the relationship between high levels of aldosterone and augmented risk of cardiovascular diseases, such as hypertension, cardiac failure, coronary artery disease and stroke. The objective of this study was to determine the prognostic role of aldosterone in patients with myocardial infarction.

Prevalence of metabolic syndrome: a comparative analysis in an unselected sample of mediterranean subjects.

Aim: The metabolic syndrome (MS) is associated with increased cardiovascular and cerebrovascular risk. This study aimed to compare the difference of the three established diagnostic criteria of MS, developed by Adult Treatment Panel III (ATP III), American Heart Association (AHA) and National Heart Lung and Blood Institute (NHLBI), and International Diabetes Federation (IDF), with regard to the prevalence of the syndrome and the ability to correctly identify individuals with cardiovascular or cerebrovascular disease or subclinical atherosclerosis.

Methods: We studied 947 consecutive patients underwent clinical evaluation between the 1997-2002.

Risk factors for contrast induced nephropathy: a study among Italian patients.

This study aimed to make a profile of patients at highest risk of developing contrast induced nephropathy (CIN) in order to take appropriate prevention measures. 591 patients undergoing coronary procedures were divided into two groups: patients with (CIN-group) and without (no-CIN) an increase in creatinine level equal or more than 25% from baseline values within 24-48 h after the coronary procedure. All patients underwent an accurate anamnesis, objective exam, hematochemical measurements, and diagnostic exams.

Impact of dual antiplatelet therapy with proton pump inhibitors on the outcome of patients with acute coronary syndrome undergoing drug-eluting stent implantation.

This study aimed to assess if proton pump inhibitors (PPIs) may reduce the effectiveness of clopidogrel, than H2 antagonist (anti-H2) in order to determine rehospitalization for acute coronary syndrome (re-ACS), target vessel revascularization (TVR) and cardiac death. This case-control study included 176 patients with ACS undergoing angioplasty (PCI) with drug-eluting stent implantation. The population was divided into two groups: PPI group (n = 121) consisting of patients receiving at discharge dual antiplatelet therapy (DAT) plus PPI and anti-H2 group (n = 55), consisting of patients receiving at discharge DAT + H2 receptor antagonist (H2RA).

Early detection of coronary artery flow and myocardial perfusion impairment in hypertensive patients evidenced by myocardial blush grade (MBG) and thrombolysis in myocardial infarction (TIMI) frame count (TFC).

Objective: In hypertensive patients with typical chest pain but absence of coronary stenosis the coronary microcirculation may be impaired, thus, our study aimed to appraise, in these subjects, the role of the coronary microcirculation, assessed by Myocardial Blush Grade (MBG) and Thrombolysis in Myocardial Infarction (TIMI) Frame Count (TFC).

Methods: A total of 95 subjects with chest pain and uninjured coronary arteries were recruited into the study: 80 subjects were hypertensive while 15 subjects were normotensive. The hypertensive subjects were divided into two subgroups: hypertensive subjects with positive scintigraphy and hypertensive subjects with negative scintigraphy.

An update on the role of markers of inflammation in atherosclerosis.

In recent years, several studies have used the measurement of carotid intima-media thickness (IMT) as a marker of early atherosclerosis: IMT has been shown to correlate significantly with the presence of coronary artery disease (CAD) and to predict fatal and not fatal cerebro- and cardio-vascular events. These findings highlight the importance of recognizing and managing early stages of atherosclerosis for effective cardiovascular prevention. Beyond traditional established cardiovascular risk factors, inflammation has been shown to be crucial throughout atherosclerosis from endothelial dysfunction to plaque rupture and thrombosis.

The predictive role of C-reactive protein in patients with hypertension and subclinical atherosclerosis.

Background: Recent guidelines published by the joint European Society of Hypertension/European Society of Cardiology have suggested the inclusion of C-reactive protein (CRP) in the standard assessment of cardiovascular risk in hypertensive patients, but few data are available on the role of CRP in patients with carotid lesions.

Methods: We studied 472 patients, 236 with and 236 without hypertension, sex- and age-matched, with and without early stages of atherosclerosis (e.g.

Endothelial dysfunction and carotid lesions are strong predictors of clinical events in patients with early stages of atherosclerosis: a 24-month follow-up study.

Background: The purpose of this study was to investigate whether the vasodilator response to brachial artery and the presence of carotid lesions may have a prognostic significance in patients with early stages of atherosclerosis.

Methods And Results: Vascular echography was performed to analyze flow-mediated vasodilatation (FMD) at the brachial artery and intima-media thickness (IMT) of carotid arteries in 84 asymptomatic patients. At baseline, we evaluated all the established traditional cardiovascular risk factors.

Peripheral artery disease: potential role of ACE-inhibitor therapy.

Subjects with peripheral arterial disease (PAD) of the lower limbs are at high risk for cardiovascular and cerebrovascular events and the prevalence of coronary artery disease in such patients is elevated. Recent studies have shown that regular use of cardiovascular medications, such as therapeutic and preventive agents for PAD patients, seems to be promising in reducing long-term mortality and morbidity. The angiotensin-converting-enzyme (ACE) system plays an important role in the pathogenesis and progression of atherosclerosis, and ACE-inhibitors (ACE-I) seem to have vasculoprotective and antiproliferative effects as well as a direct anti-atherogenic effect.

Role of inflammation and infection in vascular disease.

Relationship of infection, inflammation, and atherosclerosis has been a subject of intensive investigation in recent years. Potential mechanisms whereby chronic infections may play a role in atherogenesis are myriad. Chlamydia pneumoniae (Cp) infection in early life may accelerate atherosclerosis, leading to cardiovascular complications.

Innervated island flaps in morphofunctional vulvar reconstruction.

In this article, the authors present their own experience in vulvar reconstruction following vulvectomy using two different innervated island flaps according to the size and site of the defect. Island-flap mobilization is possible thanks to the rich blood supply of the perineal region. The methods described are a "V-Y amplified sliding flap from the pubis" and a "fasciocutaneous island flap" raised from one or both gluteal folds.

A new extended external oblique musculocutaneous flap for reconstruction of large chest-wall defects.

A new extended external oblique musculocutaneous flap utilized in the reconstruction of chest-wall defects is described. The flap is drawn as a V-Y rotation flap on the ipsilateral abdominal wall. It is laterally based, and its pedicle coincides with the five lowest costal insertions of the external oblique.
