Nerve-sparing laparoscopic disc excision of deep endometriosis involving the bowel: a single-center experience on 371 consecutives cases.

Background: Bowel endometriosis is the most common pattern of Deep Endometriosis (DE). Arising from the posterior portion of the cervix and spreading to the recto-vaginal septum, utero-sacral and parametrial ligaments could lead to a distortion of normal pelvic anatomy, causing pain and infertility. Hormonal therapy is the first-line treatment in non-symptomatic patient.

Early Detection of Microvascular Changes in Patients with Diabetes Mellitus without and with Diabetic Retinopathy: Comparison between Different Swept-Source OCT-A Instruments.

Optical coherence tomography angiography (OCT-A) has recently improved the ability to detect subclinical and early clinically visible microvascular changes occurring in patients with diabetes mellitus (DM). The aim of the present study is to evaluate and compare early quantitative changes of macular perfusion parameters in patients with DM without DR and with mild nonproliferative DR (NPDR) evaluated by two different swept-source (SS) OCT-A instruments using two scan protocols (3 × 3 mm and 6 × 6 mm). One hundred eleven subjects/eyes were prospectively evaluated: 18 healthy controls (control group), 73 eyes with DM but no DR (no-DR group), and 20 eyes with mild NPDR (DR group).

Notch signaling and progenitor/ductular reaction in steatohepatitis.

Background And Objective: Persistent hepatic progenitor cells (HPC) activation resulting in ductular reaction (DR) is responsible for pathologic liver repair in cholangiopathies. Also, HPC/DR expansion correlates with fibrosis in several chronic liver diseases, including steatohepatitis. Increasing evidence indicates Notch signaling as a key regulator of HPC/DR response in biliary and more in general liver injuries.

CXCR1 modulates the anti-inflammatory activity of hepatic dendritic cells in response to acute liver injury.

The chemokine fractalkine (CXCL1) and its receptor CXCR1 are known to mediate leukocyte chemotaxis, adhesion and survival. In the liver, CXCR1 is expressed on multiple cell types including monocytes and dendritic cells. However, the function of CXCR1 on hepatic dendritic cells (HDCs) is still poorly understood.

SerpinB3 Promotes Pro-fibrogenic Responses in Activated Hepatic Stellate Cells.

SerpinB3 is a hypoxia- and hypoxia-inducible factor-2α-dependent cystein protease inhibitor that is up-regulated in hepatocellular carcinoma and in parenchymal cells during chronic liver diseases (CLD). SerpinB3 up-regulation in CLD patients has been reported to correlate with the extent of liver fibrosis and the production of transforming growth factor-β1, but the actual role of SerpinB3 in hepatic fibrogenesis is still poorly characterized. In the present study we analyzed the pro-fibrogenic action of SerpinB3 in cell cultures and in two different murine models of liver fibrosis.

Effects of Holder pasteurization on the protein profile of human milk.

Background: The most widespread method for the treatment of donor milk is the Holder pasteurization (HoP). The available literature data show that HoP may cause degradation of some bioactive components. The aim of this study was to determine the effect of HoP on the protein profile of human milk (HM) using a GeLC-MS method, a proteomic approach and a promising technique able to offer a qualitative HM protein profile.

Human Chorionic Gonadotropin Protects Vascular Endothelial Cells from Oxidative Stress by Apoptosis Inhibition, Cell Survival Signalling Activation and Mitochondrial Function Protection.

Background/aim: Previous reports have made it hypothetically possible that human chorionic gonadotropin (hCG) could protect against the onset of pregnancy-related pathological conditions by acting as an antioxidant. In the present study we planned to examine the effects of hCG against oxidative stress in human umbilical vein endothelial cells (HUVEC).

Methods: HUVEC were subjected to peroxidation by hydrogen peroxide.

Protective effects elicited by levosimendan against liver ischemia/reperfusion injury in anesthetized rats.

As in other organs, oxidative stress-induced injury and cell death may result from free oxygen radical-dependent mechanisms and alterations in signal transduction pathways leading to apoptosis. Among the new suggested therapies for injuries caused by oxidative stress, the use of levosimendan has been reported to be quite promising. In the present study, we aimed to examine the protective effects of levosimendan against liver oxidative stress in anesthetized rats and to analyze the involvement of mitochondrial adenosine triphosphate-dependent potassium (mitoK(ATP)) channels and nitric oxide (NO).

Calcium handling in porcine coronary endothelial cells by gastrin-17.

In porcine coronary artery endothelial cells (PCAEC), gastrin-17 has recently been found to increase nitric oxide (NO) production by the endothelial NO synthase (eNOS) isoform through cholecystokinin 1/2 (CCK1/2) receptors and the involvement of protein kinase A (PKA), PKC and the β2-adrenoreceptor-related pathway. As eNOS is the Ca(2)(+)-dependent isoform of the enzyme, we aimed to examine the effects of gastrin-17 on Ca(2)(+) movements. Thus, experiments were performed in Fura-2-acetoxymethyl-ester-loaded PCAEC, where changes of cytosolic Ca(2)(+) ([Ca(2)(+)]c) caused by gastrin-17 were analysed and compared with those of CCK receptors and β2-adrenoreceptors agonists/antagonists.

Intracoronary levosimendan prevents myocardial ischemic damages and activates survival signaling through ATP-sensitive potassium channel and nitric oxide.

Objective: Levosimendan has been reported to exert cardioprotection. In this study, we have examined the cardiac effects of different doses of intracoronary levosimendan on ischemia/reperfusion injuries, and the involvement of K(ATP) channels and nitric oxide (NO).

Methods: The experiments were performed in a total of 56 anesthetized pigs.

Molecular mechanisms of liver preconditioning.

Ischemia/reperfusion (I/R) injury still represents an important cause of morbidity following hepatic surgery and limits the use of marginal livers in hepatic transplantation. Transient blood flow interruption followed by reperfusion protects tissues against damage induced by subsequent I/R. This process known as ischemic preconditioning (IP) depends upon intrinsic cytoprotective systems whose activation can inhibit the progression of irreversible tissue damage.

Understanding autophagy in cell death control.

Autophagy is an evolutionarily conserved degradation pathway which primary functions as a cell survival adaptive mechanism during stress conditions. Autophagy is a tumor suppressor process and induction of the autophagic machinery can cause cell demise in apoptosis-resistant cancer. Thus, this metabolic pathway can act either to prevent or to promote carcinogenesis, as well as to modulate the response to anticancer therapies, included drug-induced apoptosis.

Modulation of programmed forms of cell death by intracoronary levosimendan during regional myocardial ischemia in anesthetized pigs.

Purpose: Powerful mediators of programmed cell death, such as apoptosis and autophagy, can contribute to myocyte cell loss during pathological cardiac conditions. Levosimendan has been shown to exert beneficial hemodynamic effects in presence of global myocardial ischemia and heart failure through vasodilatation and increase of cardiac contractility. Recently, the intracoronary administration of a bolus levosimendan was found to exert favourable cardiac anti-stunning effects without lowering arterial pressure, which limits the use of levosimendan mainly in coronary artery disease.

New method to compute mixed water and electrolyte changes in hyponatremia: a preliminary report.

Background: We developed a new method that diagnoses when either Na or water alone are altered during electrolyte abnormalities. The aim of this study is to describe the preliminary report of an original method which can give exact or useful calculations even in mixed disorders.

Methods: when NaCl is lost, the plasma Cl (PCl) to plasma Na (PNa) ratio falls from 0.

p27Kip1 is inactivated in human colorectal cancer by cytoplasmic localization associated with activation of Akt/PKB.

p27Kip1 is a nuclear member of the Kip/Cip family of cyclin-dependent kinase inhibitors and is a negative cell cycle regulator that is thought to play a role in tumour suppression. Reduced levels of p27Kip1 are frequent in human cancers and these have been associated with poor prognosis. We have analysed p27Kip1 expression and intracellular localization in 70 human colorectal cancers by western blotting and immunohistochemistry and the results related to Akt expression and clinical pathological parameters.

Antibodies against oxidized phospholipids in laboratory tests exploring lupus anti-coagulant activity.

Lupus anti-coagulants (LA) are a variety of anti-phospholipid antibodies characterized by their capacity to interfere with phospholipid-dependent coagulation assays. LA are increasingly recognized as important predictors of thrombosis. However, the antigen specificity of LA is still poorly characterized.

Intracoronary infusion of levosimendan to treat postpericardiotomy heart failure.

Systemic hypotension limits the intravenous use of levosimendan, particularly in coronary disease. Published reports show that the intracoronary administration of levosimendan in animal models causes an increase of coronary blood flow without systemic hypotension. In this case report, the intracoronary administration of levosimendan bolus in a 74-year-old man with postpericardiotomy heart failure elicited beneficial cardiac effects, increasing both systolic and diastolic functions and blood flow in all of the grafts.

Purinergic P2Y2 receptors promote hepatocyte resistance to hypoxia.

Background/aims: ATP stimulation of purinergic P2 receptors (P2YR and P2XR) regulates several hepatic functions. Here we report the involvement of ATP-mediated signals in enhancing hepatocyte tolerance to lethal stress.

Methods: The protection given by purinergic agonists was investigated in rat hepatocytes exposed to hypoxia.

Anti-phospholipid antibodies associated with alcoholic liver disease target oxidized phosphatidylserine on apoptotic cell plasma membranes.

Background/aims: Circulating anti-phospholipid antibodies (aPL) are often present in patients with alcoholic liver disease (ALD). The observations that defects in the disposal of apoptotic corpses leads to the development of aPL prompted us to investigate whether ALD-associated aPL might recognize antigens in apoptotic cells.

Methods: Apoptosis was induced in HuT-78 human T-lymphoma and HepG2 hepatoma cells by, respectively, FAS ligation with CH11 monoclonal antibodies or the incubation with ethanol (400 mmol/L).

Cardiac angio-CT scan for planning MIDCAB.

Precise evaluation of the cardiac and thoracic anatomy of the patient is mandatory for planning safe minimally invasive direct coronary artery bypass (MIDCAB). Three-dimensional images obtained with a computed tomographic coronary angiography (angio-CT) scan make it possible to accurately visualize the intrathoracic surgical anatomy in order to check the feasibility of the direct exposure of the anatomical structures involved in the surgical procedure. Particular morphological parameters of coronary arteries such as diameter, wall calcification, and intramyocardial position as well as bypass grafts and internal thoracic artery (ITA) displacement can all be precisely defined with this method.

Signal pathway responsible for hepatocyte preconditioning by nitric oxide.

Nitric oxide (NO) improves liver resistance to hypoxia/reperfusion injury acting as a mediator of hepatic preconditioning. However, the mechanisms involved are still poorly understood. In this study, we have investigated the mechanisms by which short-term exposure to the NO donor (Z)-1-(N-methyl-N-[6-(N-methylammoniohexyl)amino])-diazen-1-ium-1,2-diolate (NOC-9) increases hepatocyte tolerance to hypoxic injury.

Signal pathway involved in the development of hypoxic preconditioning in rat hepatocytes.

Ischemic preconditioning improves liver resistance to hypoxia and reduces reperfusion injury following transplantation. However, the intracellular signals that mediate the development of liver hypoxic preconditioning are largely unknown. We have investigated the signal pathway leading to preconditioning in freshly isolated rat hepatocytes.
