Vascular atherosclerotic disease: evaluation of the whole-blood filterability and red cell membrane microrheological pattern after intravenous admini…

1990

SummaryA study was carried out in 10 patients with vascular atherosclerotic disease to investigate the effects of a single dose of 300 mg pentoxifylline, given by intravenous infusion over 30 minutes, on various macrorheological and nzicrorheological parameters. Measurements were made at baseline, at the end of the intravenous infusion and again 30 minutes later of whole-blood filterability, erythrocyte membrane fluidity (using pyrene as probe) and transverse fluidity gradient (using fluorescent fatty acids as probes). The results showed that there was a significant variation in whole-blood filterability and the red cell membrane fluidity gradient after pentoxifylline. No difference, howeve…

Sonographische Charakteristika laterozervikaler Raumforderungen

2001

UNLABELLED Sonography of the head and neck mainly focuses on tumours of the lateral neck. Even though most of these masses are enlarged lymph nodes, other tumors have to be considered. AIM To determine whether different pathological cervical masses display a characteristic sonographic morphology. METHOD On the basis of 530 sonographical findings in the neck, typical ultrasound characteristics either in B-scan or in colour coded sonography were demonstrated. RESULTS Apart from enlarged lymph nodes, it was possible to differentiate other occurrences such as branchial cysts, abscesses, laryngoceles, lipomas, neurinomas, glomus tumours, paragangliomas and also fibromas by their specific ultraso…

Polymorphonuclear leucocyte rheology and cytosolic Ca2+ content after activation in chronic renal failure

2001

SUMMARY: We evaluated polymorphonuclear leucocyte (PMN) flow properties in patients with clinically stable chronic renal failure (CRF) and in control subjects at baseline and after activation with 4-phorbol 12-myristate 13-acetate (PMA) and N-formyl-methionyl-leucyl-phenylalanine (fMLP). Initial relative flow rate (IRFR) and clogging particles (CPs) were obtained using the St. George's Filtrometer, and PMN membrane fluidity was assessed by marking PMNs with 1-(4-(trimethylamino)phenyl)-6-phenyl-1,3,5-hexatriene (TMA-DPH). PMN cytosolic Ca2+ concentration was determined by marking PMNs with Fura 2-AM. At baseline, CRF patients showed a significant increase only in PMN cytosolic Ca2+ content.…

Dental management in patients with hemostasis alteration

2011

Haemostasis is a mechanism that, through different interdependent biologic processes, has the purpose of ensuring the integrity and permeability of the circulatory system. Hemostasis term means prevention the loss of blood. Interventions or treatments in the oral cavity, in particular those with a possibility of bleeding, represent a risk for patients with disorders of hemostasis. Prevention is the key to avoid bleeding complications after oral surgical procedures and therefore it is essential a detailed medical history of the patient. The appropriate diagnosis and treatment in patients with disorders of hemostasis, depends directly in the understanding of hemostasis standard mechanisms. Em…

Mitochondrial complex I impairment in leukocytes from polycystic ovary syndrome patients with insulin resistance.

2009

Insulin resistance is a feature of polycystic ovary syndrome (PCOS) and is related to mitochondrial function.Our objective was to assess mitochondrial function by evaluating mitochondrial oxygen (O(2)) consumption, reactive oxygen species (ROS) production, levels of glutathione (GSH), the oxidized glutathione/GSH ratio, TNFalpha levels, and membrane potential. Additionally, we have evaluated mitochondrial complex I as a target of the oxidative stress responsible for PCOS in polymorphonuclear cells.This was a prospective controlled study conducted in an academic medical center.The study population consisted of 20 lean reproductive-age women with PCOS and 20 body composition-matched controls.…

Platelet membrane fluidity and platelet membrane lipid pattern in essential hypertension

1995

In a group of subjects with essential hypertension platelets were studied in resting conditions: platelet membrane fluidity was measured with the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenylhexatriene (TMA-DPH), platelet membrane cholesterol/phospholipid ratio was evaluated separating the membrane lipids with column chromatography, and platelet membrane individual phospholipids were determined using two-dimensional thin-layer chromatography. From the obtained results, it is evident that platelet membrane fluidity does not differentiate normals from hypertensives; platelet membrane cholesterol/phospholipid ratio is increased in hypertensives, while of the platelet membrane individu…

Chapter 23: Choline, a precursor of acetylcholine and phospholipids in the brain

1993

Publisher Summary The plasma level of free choline is remarkably constant at about 10 pM in animals and human. Ingestion of food, especially when rich in choline or lecithin, transiently elevates the plasma choline level up to 20 pM or more. In contrast, choline-deficient diet leads to a reduction of the plasma level by about 50%. Choline is considered an essential nutrient, which is predominantly supplied as phosphatidylcholine (lecithin). For a long time, neuroscientists have been intrigued by the fact that choline is a precursor for the biosynthesis of both acetylcholine (ACh) and phospholipids. For 50 years, lecithin has been marketed in Europe as a drug that was claimed to prevent exha…

Secondary Vitrectomy with Internal Limiting Membrane Plug due to Persistent Full-Thickness Macular Hole OCT-Angiography and Microperimetry Features: …

2020

Purpose. To study the features in OCT-angiography and microperimetry in eyes with persistent full-thickness macular hole (FTMH) closed with the secondary plana vitrectomy (PPV) with autologous internal limiting membrane (ILM) plug. Methods. Secondary PPV was performed with closing the persistent FTMH with ILM plug, C3F8 tamponade, and face-down positioning. Four patients were followed for 6 months with best corrected visual acuity (BCVA) measurement, SD-OCT and OCT-A, and microperimetry. The results were compared with the fellow eye; in two patients, it was the healthy eye, and in two remaining eyes, successfully closed FTMH after primary PPV. Results. ILM flap was integrated in all cases w…
