antifibrotic therapies should preferentially be targeted to the activated hepatic mesenchymal cells. those cells resemble wound healing myofibroblasts and synthesize an excess of extracellular matrix (ecm) proteins. they derive from quiescent hepatic stellate cells (hsc) and portal/perivascular (myo-) fibroblasts (mf). whereas various agents have been shown to inhibit hsc/mf proliferation and c...

P2Y(12) receptor antagonists are antithrombotic agents that inhibit platelet function by blocking the effects of adenosine diphosphate (ADP) at P2Y (12)receptors. However, some P2Y(12) receptor antagonists may affect platelet function through additional mechanisms. It was the objective of this study to investigate the possibility that P2Y(12) antagonists inhibit platelet function through intera...

abstract   introduction: inflammation and wear debris may be responsible for bone lysis and subsequent lost in aseptic arthroplasty. prostaglandin e2, platelet activating factor, and histamine are important mediators of inflammatory cells. we studied histopathological changes of cement-bone interface after using specific antagonists of these mediators.   methods: left and right tibiae of 120 ra...

BACKGROUND Physicians traditionally treat ulcerative colitis (UC) using a step-up approach. Given the paucity of data, we aimed to assess the cumulative probability of UC-related need for step-up therapy and to identify escalation-associated risk factors. METHODS Patients with UC enrolled into the Swiss IBD Cohort Study were analyzed. The following steps from the bottom to the top of the ther...

There are no existing guidelines supporting the withdrawal or continuation of renin-angiotensin-aldosterone system (RAAS) antagonists in the preoperative setting. RAAS antagonists include ACE inhibitors, angiotensin II receptor subtype 1 blockers and direct renin inhibitors (eg, aliskiren), as well as the aldosterone antagonists. The use of these agents before surgery has been associated with a...

Objectives: Our objective was to analyse effectiveness and safety of oral anticoagulants (OAC) for stroke prevention in non-valvular atrial fibrillation. Material methods: Population-based cohort study including adults initiating anticoagulants, either direct (DOAC) or vitamin K antagonists (VKA), during 2011–2020. Data source: SIDIAP, capturing information from the electronic health records Pr...

BACKGROUND The World Health Organization (WHO) report has predicted that major depression will become a key cause of illness-induced disability by the year 2020, second only to ischemic heart diseases. OBJECTIVES/METHODS Although a large number of antidepressant drugs (from monoamine oxidase inhibitors and tricyclic antidepressants to dual reuptake inhibitors) are available for treatment of t...

The renin-angiotensin-aldosterone system (RAAS) plays a prominent role in the pathophysiology of cardiac and renal diseases. Aldosterone leads to local effects of vasoconstriction, sodium resorption, and possibly inflammation and fibrosis in several organs. Pharmacologic manipulation of the RAAS may involve renin inhibitors, angiotensin-converting enzyme inhibitors, angiotensin II–receptor bloc...

serotonin specific reuptake inhibitors (ssri) may induce antinociception however, the mechanism of this effect is not clear. ssrls increase 5-ht levels in neuronal synapses and facilitate serotonergic activity. in this study, therefore, the activity of para-chlorophenylalanine (pcpa), which reduces 5-ht release, and 5- hydroxy tryptophan (5-htp), a precursor of 5-ht, were examined on the antino...

objective(s): hyperglycemia, oxidative stress and apoptosis have key roles in pathogenesis of diabetic neuropathy. there are local renin-angiotensin systems (rass) in different tissues such as neural tissue. local rass are involved in physiological and pathophysiological processes such as inflammation, proliferation and apoptosis. this study aimed to investigate the role of local renin-angioten...
