Involvement of the long arm of chromosome 9 in medulloblastoma in an adult.
1997
Abstract Medulloblastoma is the most common primitive neuroectodermal tumor (PNET) in children, but is very rare in adults. An isochromosome for the long arms of 17, i(17q), is found in about 30% of pediatric cases. Cytogenetic studies in adults are very scarce; only six cases have been described cytogenetically: three cases had normal karyotype, two were studied partially, and another presented only two clonal structural anomalies: del(9)(q12) and del(11)(q22). We studied the chromosomes from medulloblastoma in a 27-year-old woman and found one hypotetraploid stemline with clonal alterations. In the structural anomalies, chromosomes 3, 9, 12, and i(17q) were involved. Chromosome 9 presente…
Temperature and pressure dependence of quercetin-3-O-palmitate interaction with a model phospholipid membrane: film balance and scanning probe micros…
2004
The molecular interaction of quercetin-3-O-palmitate (QP) with dimyristoylphosphatidylcholine (DMPC) has been studied. Film balance measurements of the average molecular area vs QP molar fraction in DMPC/QP mixed monolayers showed that relevant positive deviations from ideality, i.e., a less dense monolayer packing, occurred for a temperature of 10 degrees C, below the critical melting transition temperature of DMPC monolayers T c m approximately equal 20 degrees C), while ideal behavior was observed at 37 degrees C, above this phase transition temperature. The positive deviation observed at low temperatures in the average molecular area increased with the surface pressure. Scanning probe m…
Biofouling management in anaerobic membrane bioreactors
2020
Abstract This chapter is aimed at providing an insight on the main issues around the membrane fouling in anaerobic membrane bioreactors (AnMBRs). The analysis presented here shows that membrane fouling in AnMBRs is attributed to three major factors: membrane features, operating conditions, and wastewater characteristics. Several ad-hoc strategies have been implemented in literature to mitigate membrane fouling in AnMBRs, such as gas sparging, media addition, chemical cleaning, and membrane rotation/vibration. Among them, gas sparging is considered the most expensive strategy due to the high power requirement of the gas blower (up to 1.345 kWh m− 3). An accurate experimental and modeling ana…
OXYGEN SOLUBILITY IN NORMAL HUMAN BLOOD
1981
Publisher Summary This chapter describes oxygen solubility in normal human blood. The most crucial problem in measuring physically dissolved oxygen in blood is the prevention of oxygen binding by hemoglobin (Hb). The chapter discusses a study for the re-determination of oxygen solubility in untreated human blood. The oxygen concentration was measured by a photometric method and the Hb-concentration was determined by the cyanohemoglobin method. Oxygen solubility in normal and untreated blood is a linear function of the Hb-concentration. Hemoglobin in the reduced state has a greater influence on oxygen solubility than hemoglobin. Red cell membranes have no measureable effect on the oxygen sol…
The University of Opole and Biblical and Semitic Rhetoric
2017
The goal of this presentation is not to perform scientific research but to present the group of students, who form the Student’s Research Group of Theology at Universitas Opoliensis in Poland. The aim of the group is the study of Biblical and Semitic Rhetoric and its popularization in the country. The object of the work of these young scholars is entwined with three Learning Seminars and the International Conference of the RBS in Rome. In Poland they have become known by organizing in schools educational workshops «The Lord’s Prayer & Menorah». Their particular methodology of cooperative work is based on human values such as mutual listening and dialogue. Listening is not understood in its …
Inhalational or intravenous anesthetics for craniotomies? Pro inhalational.
2006
In neurosurgery, anesthesiologists and surgeons focus on the same target - the brain. The nature of anesthetics is to interact with brain physiology, leading to favorable and adverse effects. Research in neuroanesthesia over the last three decades has been dedicated to identifying the optimal anesthetic agent to maintain coupling between cerebral blood flow and metabolism, keep cerebrovascular autoregulation intact, and not increase cerebral blood volume and intracranial pressure.Sevoflurane is less vasoactive than halothane, enflurane, isoflurane, or desflurane. The context sensitive half-life is short and similar to that of desflurane, which translates into fast on and offset. Compared wi…
Anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing chemotherapy.
2000
OBJECTIVE: To characterize the effects of anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing regimens with dosages ·50 mg·m−2. METHODS: A prospective, cross-sectional, noncontrolled study was performed to analyze acute vomiting during the first 24 hours in patients treated in a Spanish hospital. The patients received an intravenous combination of drugs (2 doses of metoclopramide 3 mg/kg, dexamethasone 20 mg) as first-choice antiemetic therapy. Intravenous ondansetron 8 mg and dexamethasone 20 mg served as an alternative regimen in patients <30 years old with a history of extrapyramidal manifestations or emesis in previous cycles. Therapeutic …
The Effectiveness of 0.6% Povidone Iodine Eye Drops in Reducing the Conjunctival Bacterial Load and Needle Contamination in Patients Undergoing Anti-…
2019
The study purpose was to assess the efficacy of a preservative-free 0.6% povidone iodine eye drops as perioperative prophylactic treatment for reducing conjunctival bacterial load and the rate of needle contamination in patients undergoing intravitreal anti-vascular endothelial growth factor injection. Enrolled patients were randomized to either the study group (0.6% povidone iodine, three day-prophylactic treatment before the injection) or to the control group (placebo, three day-prophylactic treatment). Conjunctival swabs were obtained before and after the prophylactic treatment in both groups. Intravitreal injections were performed in a sterile fashion. The injection needle and a control…
Rotavirus gastroenteritis in Italian children: can severity of symptoms be related to the infecting virus?
2001
The aim of our study was to determine whether the severity of rotavirus gastroenteritis may be related to the different characteristics of infecting viral strains. The severity of clinical symptoms in 401 children with acute rotavirus gastroenteritis was assessed using a scoring system for frequency and duration of vomiting, diarrhea, and fever, as well as the patients' requirements for intravenous rehydration. Rotavirus strains were characterized by determining the electropherotype of their double-stranded RNA, the G type and subgroup by a panel of monoclonal antibodies, and the P type by reverse transcription-polymerase chain reaction. Strains with a short electropherotype, G2P[4] type, a…
The cultivable human oral gluten-degrading microbiome and its potential implications in coeliac disease and gluten sensitivity
2013
AbstractCoeliac disease is characterized by intestinal inflammation caused by gluten, proteins which are widely contained in the Western diet. Mammalian digestive enzymes are only partly capable of cleaving gluten, and fragments remain that induce toxic responses in patients with coeliac disease. We found that the oral microbiome is a novel and rich source of gluten-degrading organisms. Here we report on the isolation and characterization of the cultivable resident oral microbes that are capable of cleaving gluten, with special emphasis on the immunogenic domains. Bacteria were obtained by a selective culturing approach and enzyme activities were characterized by: (i) hydrolysis of paranitr…
