Bazedoxifene increases the proliferation of human arterial endothelial cells but does not affect the expression of cyclins A, B, and D1 and of p27Kip1

2021

Endothelial dysfunction and denudation are considered a first step in atherosclerosis. Endothelial proliferation is key for cellular repair. The effect of bazedoxifene on the vascular endothelium h...

Endothelial Dysfunction and Inflammation in Ischemic Stroke Pathogenesis

2020

: Stroke is a heterogeneous disease, and within the broad category of brain ischemia and its subtypes vary dramatically in its etiology. : The endothelium can regulate the vascular homeostasis by modulating processes of vascular dilation and constriction by producing and secreting cytokines and chemical mediators, and inflammation represents one of the most important factors that contribute to alteration in vessel structure and function by dysregulation of this fine balance. : Endothelial dysfunction means a basic determinant of the vascular damage, which can be identified in all different clinical subtypes of stroke, and, recently, it has been recognized as an interesting determinant of c…

Primary hypercholesterolemia and development of cardiovascular disorders: Cellular and molecular mechanisms involved in low-grade systemic inflammati…

2021

Primary hypercholesterolemia, a metabolic disorder characterized by elevated circulating levels of cholesterol products, mainly low-density lipoproteins, is associated with arteriosclerosis development. Cardiovascular disease, predominantly myocardial infarction and stroke, remains the main cause of death worldwide, with atherosclerosis considered to be the most common underlying pathology. In addition to elevated plasma levels of low-density lipoproteins, low-grade systemic inflammation and endothelial dysfunction seem to be the main drivers of premature atherosclerosis. Here we review current knowledge related to cellular and molecular mechanisms involved in low-grade systemic inflammatio…

Microcirculatory dysfunction in sepsis: a pathogenetic basis for therapy?

2000

Sepsis is a frequent complication of multiple organ dysfunction syndrome and remains a major problem of intensive care medicine. It is also a common factor in the final cause of death in hospital populations. Clinical observations, assisted by invasive monitoring techniques as well as pathological-anatomical studies, clearly indicate that microcirculatory dysfunction lies at the centre of sepsis pathogenesis. Numerous animal models, from rodents to primates, many of which employ bacteria or their toxins, especially endotoxins, have helped to shed light on the pathomechanisms leading to this dysregulation in the peripheral circulation. Among these are activation of humoral and cellular infla…

Reducing the Cost of Being the Boss: Authentic Leadership Suppresses the Effect of Role Stereotype Conflict on Antisocial Behaviors in Leaders and En…

2021

What drives entrepreneurs to engage in antisocial economic behaviors? Without dismissing entrepreneurs’ agency in their decision-making processes, our study aims to answer this question by proposing that antisocial economic behaviors are a dysfunctional coping mechanism to reduce the psychological tension that entrepreneurs face in their day-to-day activities. Further, given the overlap between the male gender role stereotype and both leader and entrepreneur role stereotypes, this psychological tension should be stronger in female entrepreneurs (or any person who identifies with the female gender role). We argue that besides the well-established female gender role – leader role incongruence…

Disfunzioni sessuali, farmaci antiepilettici e profilo ormonale sierico negli uomini affetti da epilessia

2012

Razionale ed obiettivi: Le disfunzioni sessuali sono un problema relativamente comune nei pazienti di sesso maschile affetti da epilessia, la cui.prevalenza varia dal 38-71%. La loro eziologia non è conosciuta e potrebbe essere multifattoriale; possono essere implicati nella loro genesi sia l’epilessia che l’utilizzo di farmaci antiepilettici (FAE). L’assunzione di farmaci per la terapia dell’epilessia può essere all’origine della presenza di DS e di alterazioni ormonali e riproduttive in questa popolazione di pazienti. Lo scopo dello studio è valutare l’incidenza delle DS negli uomini con epilessia, valutando il tipo di epilessia, la frequenza delle crisi, il tipo di FAE utilizzato, il pro…

Disfunzioni sessuali, farmaci antiepilettici e profilo ormonale sierico negli uomini affetti da epilessia. Sexual disfunctions, antiepileptic drugs, …

2012

Sexual dysfunctions (SD) are a relatively common problem in men with epilepsy; the prevalence ranges from 38-71%. Etiology may be multifactorial and may involve both the epilepsy and the use of antiepileptic drugs. The purpose of this study was to evaluate the incidence of SD in epileptic men, assessing the type of epilepsy, seizures frequency, antiepileptic drugs used, the serum hormonal profile and the presence of psychiatric disorders.

Cell-mediated lipoprotein transport: A novel anti-atherogenic concept

2010

Lipoprotein transport is thought to occur in the plasma compartment of the blood, where lipoproteins are modulated by various enzymatic reactions. Subsequently, lipoproteins can migrate through the endothelial barrier to the subendothelial space or are taken up by the liver. The interaction between pro-atherogenic (apoB-containing) lipoproteins and blood cells (especially monocytes and macrophages) in the subendothelial space is well known. This lipoprotein-inflammatory cell interplay is central in the development of the atherosclerotic plaque. In this review, a novel interaction is described between lipoproteins and both leukocytes and erythrocytes in the blood compartment. This lipoprotei…
