Abstract
BACKGROUND This article provides an up-to-date overview of pericardial effusion in oncological practice and a guidance on its management. Furthermore, it addresses the question of when malignancy should be suspected in case of newly diagnosed pericardial effusion. MAIN BODY Cancer-related pericardial effusion is commonly the result of localization of lung and breast cancer, melanoma, or lymphoma to the pericardium via direct invasion, lymphatic dissemination, or hematogenous spread. Several cancer therapies may also cause pericardial effusion, most often during or shortly after administration. Pericardial effusion following radiation therapy may instead develop after years. Other diseases, such as infections, and, rarely, primary tumors of the pericardium complete the spectrum of the possible etiologies of pericardial effusion in oncological patients. The diagnosis of cancer-related pericardial effusion is usually incidental, but cancer accounts for approximately one third of all cardiac tamponades. Drainage, which is mainly attained by pericardiocentesis, is needed when cancer or cancer treatment-related pericardial effusion leads to hemodynamic impairment. Placement of a pericardial catheter for 2-5 days is advised after pericardial fluid removal. In contrast, even a large pericardial effusion should be conservatively managed when the patient is stable, although the best frequency and timing of monitoring by echocardiography in this context are yet to be established. Pericardial effusion secondary to immune checkpoint inhibitors typically responds to corticosteroid therapy. Pericardiocentesis may also be considered to confirm the presence of neoplastic cells in the pericardial fluid, but the yield of cytological examination is low. In case of newly found pericardial effusion in individuals without active cancer and/or recent cancer treatment, a history of malignancy, unremitting or recurrent course, large effusion or presentation with cardiac tamponade, incomplete response to empirical therapy with nonsteroidal anti-inflammatory, and hemorrhagic fluid at pericardiocentesis suggest a neoplastic etiology.

Abstract
Accurate measurements of concentration and ruminal degradability of corn silage starch is necessary for formulation of diets that meet the energy requirements of dairy cows. Five corn silage hybrids ensiled for 0 (unfermented), 30, 60, 120, and 150 d were used to determine the effects of ensiling time on starch degradability of corn silage. In addition, the effects of grind size of silage samples on 7-h in vitro starch degradability and the relationship between in vitro, in situ and near-infrared reflectance spectroscopy (NIRS) starch degradability were studied. In situ disappearance of corn silage starch increased from 0 to 150 d of ensiling, primarily as a result of an increase in the washout or rapidly degraded fraction of starch, particularly during the first 60 d of ensiling. When analyzed in vitro and by NIRS, ensiling time increased corn silage starch degradability either linearly or to a greater extent during the first 2 mo of ensiling. Differences in in situ starch disappearance among corn silage hybrids were apparent during the first 2 mo of ensiling but were attenuated as silages aged. No differences among hybrids were detected using a 7-h in vitro starch digestibility approach. Results from the in vitro subexperiment indicate that 7-h in vitro starch degradability was increased by reducing grind size of corn silage from 4 to 1 mm, regardless of ensiling duration. Fine grinding corn silages samples (i.e., 1-mm sieve) allowed distinguishing low- from medium- and high-starch degradability rated hybrids. Correlations among in situ, in vitro and NIRS measurements for starch degradability were medium to high (r ≥0.57); however, agreement among methods was low (concordance correlation coefficient ≤0.15). In conclusion, ensiling time linearly increased degradation rate of corn silage resulting in greater in situ starch disappearance after 150 d of ensiling. Reductions in grind size from 4 to 1 mm resulted in greater in vitro starch degradability, regardless of ensiling duration. Strong correlation but low agreement between starch degradability methods suggest that absolute estimations of corn silage starch degradability will vary, but all methods can be used to assess the effect of ensiling time on starch degradability.

Abstract
In a previous study, the coexistence of different aggregation pathways of insulin and β-amyloid (Aβ) peptides was demonstrated by correlative stimulated emission depletion (STED) microscopy and atomic force microscopy (AFM). This had been explained by suboptimal proteins labeling strategies that generate heterogeneous populations of aggregating species. However, because of the limited number of proteins considered, the failure of the fluorescent labeling that occurs in a large portion of the aggregating fibrils observed for insulin and Aβ peptides, could not be considered a general phenomenon valid for all molecular systems. Here, we investigated the aggregation process of α-synuclein (α-syn), an amyloidogenic peptide involved in Parkinson's disease, which is significantly larger (MW ∼14 kDa) than insulin and Aβ, previously investigated. The results showed that an unspecific labeling procedure, such as that previously adopted for shorter proteins, reproduced the coexistence of labeled/unlabeled fibers. Therefore, a site-specific labeling method was developed to target a domain of the peptide scarcely involved in the aggregation process. Correlative STED-AFM illustrated that all fibrillar aggregates derived from the aggregation of α-syn at the dye-to-protein ratio of 1 : 22 were fluorescent. These results, demonstrated here for the specific case of α-syn, highlight that the labeling artifacts can be avoided by careful designing the labeling strategy for the molecular system under investigation. The use of a label-free correlative microscopy technique would play a crucial role in the control of the setting of these conditions.

Abstract
Skeletal muscle differentiation was proven to be influenced by changes in the substrate stiffness. However, a lack of knowledge features this field, concerning skeletal muscle tissues obtained from human induced pluripotent stem cells. Here we report the fabrication of polydimethylsiloxane-based substrates in a range of stiffness values from 3.5 to 141 kPa and the response of human induced pluripotent stem cells cultured on them for 5 days. The substrates were able to sustain cell adhesion and proliferation throughout the whole period. An inversely proportional relationship (although not significant) was found between the proliferation rate and the substrate stiffness. Initial analyses of iPSCs skeletal muscle differentiation shown no influences on markers of the early stages. These results lay the foundations for further studies on the influence of extrinsic mechanical stimuli on induced pluripotent stem cells-derived skeletal muscle tissues.

Abstract
Accurate analysis of degradability of silage neutral detergent fiber (NDF) is important for diet formulation and to predict lactational performance of dairy cows. In this study, 5 corn silage hybrids ensiled for 0 (unfermented), 30, 60, 120, and 150 d were used to determine the effects of ensiling time on silage neutral detergent fiber degradability (NDFD) and to assess the relationships between near-infrared reflectance spectroscopy (NIR) NDF-related analyses and in situ NDFD variables. In addition, the relationships between dietary concentration of indigestible NDF, 288-h incubation (iNDF288), or undegraded NDF, 240-h incubation (uNDF240), and in vivo total-tract apparent organic matter and NDF digestibility were studied in total mixed ration samples from 16 experiments with lactating dairy cows. Ensiling time had no effect on silage NDF concentration; however, the ratio of acid detergent fiber ÷ NDF increased, and estimated hemicellulose concentration decreased quadratically with ensiling time. Also, concentration of NDF-bound protein decreased, and that of lignin increased linearly with ensiling time. These changes in silage fiber composition resulted in a linear decrease in in situ effective degradability of silage NDF with increasing ensiling time. The indigestible fraction of NDF and concentration of structural carbohydrates were not affected by ensiling time. Correlations of in situ NDFD variables with laboratory NIR NDFD analyses were weak to moderate. The relationship of corn silage uNDF240 with lignin concentration or 30-h NDFD (all NIR analyses) was remarkably good (R2 = 0.73 and 0.88, respectively). The relationship between in situ iNDF288 concentration (but not uNDF240) and in vivo total-tract apparent digestibility of dietary organic matter and NDF was good (R2 = 0.72 and 0.80, respectively). In conclusion, in situ degradability of silage NDF linearly decreased from 0 to 150 d ensiling time, primarily caused by a decrease in concentrations of hemicellulose and NDF-bound protein. In situ NDF degradability measurements and common laboratory NIR NDF-related analyses were generally poorly correlated. We found a good relationship between in vivo NDF digestibility and dietary concentration of iNDF288 determined in situ, but the relationship with uNDF240 was poor.

Abstract
Mutation or multiplication of the alpha-synuclein (Syn)-encoding gene is frequent cause of early onset Parkinson's disease (PD). Recent evidences point to the pathogenic role of excess Syn also in sporadic PD. Syn is a cytosolic protein, which has been shown to be released from neurons. Here we provide evidence that extracellular Syn induces an increase in surface-exposed glucose-related protein of 78 kDa (GRP78), which becomes clustered in microdomains of the neuronal plasma membrane. Upon interacting with Syn, GRP78 activates a signaling cascade leading to cofilin 1 inactivation and stabilization of microfilaments, thus affecting morphology and dynamics of actin cytoskeleton in cultured neurons. Downregulation of GRP78 abolishes the activity of exogenous Syn, indicating that it is the primary target of Syn. Inactivation of cofilin 1 and stabilization of actin cytoskeleton are present also in fibroblasts derived from genetic PD patients, which show a dramatic increase in stress fibers. Similar changes are displayed by control cells incubated with the medium of PD fibroblasts, only when Syn is present. The accumulation of Syn in the extracellular milieu, its interaction with the plasma membrane and Syn-driven clustering of GRP78 appear, therefore, responsible for the dysregulation of actin turnover, leading to early deficits in synaptic function that precede neurodegeneration.

Abstract
BACKGROUND α(s1)-Casein is one of the four types of caseins, the largest protein component of bovine milk. The lack of a compact folded conformation and the capability to form micelles suggest a relationship of α(s1)-casein with the class of the intrinsically disordered (or natively unfolded) proteins. These proteins are known to exert a stabilizing activity on biomolecules through specific interaction with hydrophobic surfaces. In the present work we focused on the effect of α(s1)-casein on the fibrillogenesis of 1-40 β-amyloid peptide, involved in Alzheimer's disease. METHODS The aggregation kinetics of β-peptide in presence and absence of α(s1)-casein was followed under shear at 37°C by recording the Thioflavine fluorescence, usually taken as an indicator of fibers formation. Measurements of Static and Dynamic Light Scattering, Circular Dichroism, and AFM imaging were done to reveal the details of α(s1)-casein-Aβ(1-40) interaction. RESULTS AND DISCUSSIONS α(s1)-Casein addition sizably increases the lag-time of the nucleation phase and slows down the entire fibrillization process. α(s1)-Casein sequesters the amyloid peptide on its surface thus exerting a chaperone-like activity by means a colloidal inhibition mechanism. GENERAL SIGNIFICANCE Insights on the working mechanism of natural chaperones in preventing or controlling the amyloid aggregation.

Abstract
AIM Oral disorders have a psycho-social impact on the quality of life, that can be measured with instruments as the Oral Health Impact Profile questionnaire (OHIP). Using the OHIP, we evaluated if and how the orofacial pain can affect the quality of life in temporomandibular disorders (TMD) patients. METHODS A transversal case-control study was carried out. Study subjects were patients referred to the Section of Prosthetic Dentistry and Temporomandibular Disorders of the University of Pavia (Italy). Subjects were recruited sequentially until the target of 124. The controls were 61 "pain free" subjects, who were recruited from the same clinic. In analyzing the data, the chi squared test was used for categorical data, and t test and one-way analysis of variance were used for numerical scores. RESULTS The subjects in this study were predominantly females (83.9%). The mean age of subjects was 35.1 years (standard deviation= 14.0). The most frequently reported symptoms were pain in the temporomandibular joint (TMJ) (87.1%). The data showed that orofacial pain had an important impact on daily life (p<0.05) and that its most common outcomes were psychological. CONCLUSIONS Comparison with a "pain free" population clearly indicated that orofacial pain and associated symptoms negatively affect the quality of life of TMD patients.

Abstract
Although devoid of proliferative capacity, polymorphonuclear neutrophils (PMN) express receptors for haemopoietic growth factors and need growth factors for survival and functional stimulation. This study showed that in vitro treatment of human PMN with GM-CSF for up to 48 h increases cell surface expression of the beta 2-integrin molecules CD11b/CD18 and CD11c/CD18 and of the receptor for the chemotactic peptide fMLP. Such modifications are usually expression of PMN activation. PMN treated with GM-CSF also displayed increased phagocytosis of latex particles and enhanced oxidative burst and superoxide anion release. Since integrins mediate PMN adhesion to endothelium, homotypic adhesion, chemotaxis/phagocytosis and the triggering of respiratory burst, our results suggested that functional stimulation of PMN persisted following prolonged exposure of PMN to growth factors and that it was not a temporary phenomenon which lasted only for the first 12-24 h of treatment. We also used oligonucleotides antisense to the Bcr gene mRNA to inhibit expression of the gene and evaluate its function in PMN, following the recent observation that PMN from Bcr-null mutant mice produced increased amounts of reactive oxygen metabolites upon activation. The antisense oligonucleotides had no effect on the parameters investigated. This may indicate that increased production of O2 by neutrophils in which the Bcr gene is not expressed requires either that gene expression is absent in the earlier stages of myeloid differentiation/maturation, so that when inhibition occurs in the terminally differentiated neutrophils their functional status is no longer influenced, or that the residual low-level expression of the gene which may be present in the antisense-treated cells is sufficient to provide a normal response to stimulation.

Abstract
The aim of this study was to assess the expression of CD11b/CD18 integrin adhesion molecules on the phagocytes of patients with ischaemic diseases, and to evaluate the concentration of soluble adhesion molecules that are released from endothelium (sICAM-1) and from phagocytes (sL-selectin). A total of 370 patients were enrolled: 120 with coronary artery disease (CAD); 50 with peripheral artery occlusive disease (PAOD); and 200 control subjects with no clinical manifestations of ischaemic disease. CD11b/CD18 integrin was detected by flow cytometry, whereas sL-selectin and sICAM-1 concentrations were detected using a sandwich-type immunoassay. CD11b/CD18 integrin expression was found to be higher in the patients with ischaemic disease than in the control subjects (P < 0.001). The PAOD patients had higher values of CD11b/CD18 integrin than the CAD ones (P < 0.01). The concentration of soluble adhesion molecules did not show any significant differences within the three groups (P = NS). The high expression of CD11b/CD18 integrin in ischaemic disease patients may depend on the increased, but probably stable, cytokine network that has been demonstrated to occur in chronic ischaemic diseases: the difference observed between PAOD and CAD patients could be the consequence of higher inflammatory activation probably resulting from the greater extent of the atherosclerotic process in PAOD, or of the more localized ischaemic area in CAD patients. CD11b/CD18 can therefore be considered a marker of chronic phagocyte activation during ischaemic disease. On the other hand, sICAM and sL-selectin concentrations were found to be within the normal range; they have recently been considered as a marker for acute ischaemic events and acute inflammatory process activation. Our results confirm that in uncomplicated atherosclerosis no acute inflammatory process activation should occur.

Abstract
In order to better elucidate the immunological effect of opioid abuse in the absence of HIV infection as a confounding factor, granulocyte function was investigated in 3 groups of HIV negative subjects including 20 active parenteral heroin abusers (E), 20 long-treatment methadone-maintained former opiate abusers (M) and 20 healthy controls. Chemotaxis to fMLP, casein and activated plasma were markedly and similarly reduced (approximately 50%) in both E and M groups, as true for superoxide production after fMLP and PMA stimulation, 47% decrease of C values. PMNs of E and M subjects also exhibited a very marked and similar reduction in the expression of CD11b/CD18 integrin receptors after fMLP treatment with values that were lower than 10% of those in controls as observed by flow cytometry. In parallel, PMNs of E and M individuals presented an approximately four fold increase in opioid receptors number compared to controls, a significant inverse correlation existing between the increase in opiate receptors and defective chemotaxis. The possible mechanism retaining the observed changes in PMNs of E and M individuals are discussed.

Abstract
This study has been designed to demonstrate the in vivo effects of iloprost therapy on expression of adhesion molecules on phagocytes. Sixty patients suffering from peripheral arterial occlusive disease (PAOD) and/or from skin ulcers due to secondary progressive systemic sclerosis (PSS) were enrolled in a double-blind controlled parallel study. Thirty patients (group I) underwent iloprost infusion and 30 patients (group II) were treated with aspirin. Clinical assessment and measurement of phagocyte activation in vivo, using quantitative flow cytometry, were performed on entry and after 6 h on the first day of therapy. After 3 months of therapy, complete healing of all cutaneous lesions was observed in 84% of the patients treated with iloprost compared with the control patients (P < 0.001). Neutrophils and monocytes of PAOD and PSS patients showed a significant decrease in the expression of the alpha M beta 2 integrin adhesion receptor after 6 h of iloprost infusion. Neutrophils and monocytes released a lower amount of anion superoxide (O2-) after 6 h of iloprost treatment. These data confirm other clinical observations but demonstrate that in vivo this drug modifies the expression of the alpha M beta 2 integrin of phagocytes that has a key role in leukocyte-endothelium interactions in cases of inflammation and thrombosis.

Abstract
The effect of L-propionylcarnitine on patients with left ventricular dysfunction (EF < 45%) NYHA class II, symptomatic despite therapy with digitalis and diuretics was evaluated in a phase II parallel, double-blind, randomized, placebo-controlled study. Fifty patients (28 men and 22 women) aged 37-70 years received 1.5 g of L-propionylcarnitine or placebo on a random basis as oral treatment for 6 months. At baseline, during a 7 day placebo run-in period, and during the 6-month treatment bicycle exercise test, M-B mode and Doppler echocardiography, and clinical evaluation (clinical score) were repeatedly performed. The analysis of variance for repeated measurements showed a statistically significant difference (P < 0.01) in the mean value of exercise time between the treatments over the period of the study. There was a final increase of 0.36 min in the placebo group, 1.4 min in the treated group and a minor production of lactate during exercise in the treated group. Left ventricular shortening fraction and left ventricular ejection fraction showed a significant increase in the L-propionylcarnitine group (respectively P < 0.01 and P < 0.0001) whereas no difference was apparent in the placebo group. Stroke volume index and cardiac index showed significant increments in the treated group (P < 0.05) and systemic vascular resistance was lowered (P < 0.05). No haemodynamic variations were observed in the placebo group, and the clinical score showed a significant improvement in the L-propionylcarnitine treated group. In conclusion, L-propionylcarnitine treatment was shown to improve patient symptomatology and effort tolerance.

Abstract
The present report describes an unusual case (apparently the 10th in the world literature) of a type-A aortic dissection with full circumferential detachment of the ascending aortic intima and intussusception thereof into the aortic arch and descending aorta, partly occluding the arch vessels. Computed tomographic scanning and 2-dimensional echocardiography failed to detect an intimal flap and a false lumen in the ascending aorta. Aortic dissection was visualized by aortography. The ascending aorta was surgically repaired and the aortic valve resuspended. The pertinent literature is reviewed.

Abstract
Twenty-six patients with an intracardiac myxoma underwent surgical resection at our institution from 1977 through 1992. Left atrial myxoma was diagnosed in 22 patients, left ventricular in 1, right atrial in 2, and right ventricular in 1. Six patients were asymptomatic; preoperative symptoms included dyspnea, arrhythmias, embolic episodes, and syncope. The diagnosis was established with transthoracic echocardiography in all cases but one. Surgery was performed in all cases with the aid of cardiopulmonary bypass with moderate hypothermia and cold crystalloid cardioplegia. One patient with a left ventricular myxoma died in a comatose state during the immediate postoperative period. Long-term clinical and echocardiographic evaluation was performed in 19 patients; results were excellent (all the patients were in New York Heart Association functional class I or II), and no recurrences were documented. The clinical characteristics, diagnostic methods, and surgical approach are presented and discussed.

Abstract
Amlodipine, a novel dihydropyridine calcium-antagonist, was compared to slow-release nifedipine in a short-term study on 40 patients with mild to moderate essential hypertension, in order to assess the efficacy and tolerability of two different dihydropyridine calcium-antagonists with short and long half-life. After a two-week single-blind placebo period, patients were given, in a randomized sequence, amlodipine (5 or 10 mg/day od, 20 patients) or nifedipine s.r. (20 or 40 mg BID, 20 patients). At the end of treatment (12 weeks) a significant lowering of arterial pressure was obtained after 24h from the administration of amlodipin (-34/-17 mmHg) and after 12h from the administration of nifedipine s.r. (-33/-16 mmHg). Furthermore, with both drugs, no significant changes in heart rate and ECG have been reported. Amlodipine was better tolerated than nifedipine, as shown by the lower incidence of side effects. Therefore amlodipine proved to be an effective and well tolerated drug in the therapy of mild to moderate hypertension.

Abstract
The efficacy and safety of amlodipine (5-10 mg once daily) and diltiazem (30-60 mg three times daily) were compared in 40 patients with symptomatic myocardial ischemia. A 2-week placebo run-in period was followed by 10 weeks of open treatment with amlodipine (n = 20) or diltiazem (n = 20). Concomitant treatment with other antianginal drugs (except other calcium antagonists) was permitted throughout the study. The baseline blood pressures were 166/93 and 160/91 mm Hg for the amlodipine group and diltiazem groups, respectively. Amlodipine (mean final daily dose of 9.25 mg) reduced blood pressure by - 27/-11 mm Hg compared with a reduction of - 17/-8 mm Hg for diltiazem (mean final daily dose of 180 mg), with no significant effects on heart rate. A significantly greater reduction in the mean rate-pressure product was observed after amlodipine (-20.8%) when compared with diltiazem (-13.1%) (p < 0.05). Amlodipine reduced the mean weekly angina attacks to zero after 6 weeks of treatment (baseline of 3.4 attacks/week) compared with a reduction from 3.3 to 0.35 attacks/week after 10 weeks of treatment with diltiazem. The amlodipine group had a reduction in mean nitroglycerin consumption from baseline of 1.1 mg/week to zero by week 6, whereas the diltiazem group had reduced mean weekly intake from 0.9 to 0.1 mg at the end of the study. The overall assessment of clinical efficacy was excellent for 100% of amlodipine patients compared with 40% of diltiazem patients. The high-density lipoprotein cholesterol/total cholesterol ratio increased by 15.8% with amlodipine compared to diltiazem, which produced a 4.5% decrease. Amlodipine decreased triglycerides by 7.1% compared to 4.5% with diltiazem. The incidence and severity of side effects was comparable for both treatments. Amlodipine once daily was effective and well tolerated in the treatment of patients with symptomatic myocardial ischemia and was comparable with diltiazem three times daily.

Abstract
Forty patients with mild-to-moderate arterial hypertension were randomized for double-blind treatment with ketanserin (20 mg b.i.d.) vs. captopril (25 mg b.i.d.) for fifteen days. Diastolic pressure was normalized (less than 90 mmHg) in 11 out of 20 patients of both groups. Of the 18 patients not responding to monotherapy, 17 were treated for 45 days with a combination of both drugs at the same dosages. Diastolic blood pressure was normalized in 15 out of these 17, and in one patient it was reduced by more than 10%. Thus the success rate of therapy was 94%.

Abstract
A group of 30 patients with II-III NYHA class cardiac insufficiency was treated with ibopamine in association with other drugs for a 6-month period. The patients were submitted to a 24-h ambulatory ECG Holter monitoring, chest X-ray, Doppler echocardiography in order to calculate total peripheral vascular resistance. Blood levels of aldosterone and renin-angiotensin activity in plasma were also measured, together with norepinephrine excretion. The measurements and recordings were performed in basal conditions before the trial, and were repeated after the first, second, third and sixth month. Laboratory tests were performed at the baseline and after 6 months. The results showed a significant decline in the number of ventricular and supraventricular ectopic beats after treatment. Heart rate did not change. Cardio-thoracic ratio decreased significantly along with peripheral vascular resistance. A very noticeable decline in all three neurohormonal parameters, i.e. norepinephrine excretion, blood level of aldosterone and renin activity in plasma was observed after 1 month's treatment, and this reduction was still present without any attenuation after 6 months. No significant changes were observed in routine laboratory tests.

Abstract
Sixteen angina patients were submitted to echocardiographic examination during the cold pressor test and during hand grip. Certain left ventricular function echocardiographic parameters were assessed in these subjects and in a further 14 patients presenting negative histories for cardiovascular diseases who represented the control group. Of the two tests associated with echocardiography, the cold pressor test appeared capable of inducing the more evident changes on left ventricular function compared to isometric effort in subjects suffering from ischaemic cardiopathy.

Abstract
Left ventricular (LV) performance was studied in young patients with severe chronic anemia due to beta-thalassemia major, intermedia, and in healthy control subjects. M-mode echocardiograms were recorded in each patient and semiautomatic computerized analysis of the tracings provided data relating to LV performance. Then a statistical analysis of the difference between each specific thalassemic group and the normal subjects was made using Student's t-test for unpaired data. The study showed that cardiac dysfunction is more serious in major than in intermediate beta thalassemia. A follow-up one year later showed a progressive deterioration of the cardiac indices, in spite of treatment with desferrioxamine. A handgrip test was performed in the follow-up study, which permitted us to distinguish different groups relative to the changes in LV performance indices. Our findings indicate that echocardiography provides a simple noninvasive means for assessing changes in the cardiac structure and function, which should also prove useful in the serial evaluation of patients at risk of developing myocardial iron deposition.

Abstract
The discovery tha carnitine takes an active part in the transportation of long-chain acyl residues across the inner mitochondrial membrane dates back to 1958. It has been shown experimentally tha a reduction in myocardial carnitine content takes place after 15-30 min of ischemia. L-carnitine was administered orally in doses of 3 g/day for 30 days to 16 subjects with effort-induced angina and to 14 healthy subjects. A bicycle ergometer exercise test revealed a 1.5 mm (mean) depression of the ST-T segment in the angina subjects after pharmacological wash-out and a 1 mm depression in the same subjects after carnitine treatment. M-code echocardiography showed positive changes in a number of ventricular function parameters in the angina subjects and also, to a lesser extent, in the healthy controls.
