Altered adipose tissue metabolism in offspring of dietary obese rat dams.
2011
To investigate further the mechanisms of developmental programming, we analysed the effects of maternal overnutrition and of postnatal high-fat feeding on adipose tissue metabolism in the offspring. Postnatal changes in serum adiponectin, leptin and TAG [triacylglycerol (triglyceride)] levels, adipose tissue TAGs, fatty acids and enzyme activities were determined in offspring of cafeteria-diet-fed dams during gestation and lactation, weaned on to standard chow or on to cafeteria diet. Obese rats showed higher adiposity (+35% to 85%) as well as a significant increase in serum glucose, insulin, leptin, adiponectin and TAG levels (P<0.01) and adipose tissue LPL (lipoprotein lipase) and …
Peroxisome Proliferator-Activated Receptor Deficiency Increases the Risk of Maternal Abortion and Neonatal Mortality in Murine Pregnancy with or with…
2006
We assessed the implication of peroxisome proliferator-activated receptor (PPAR) alpha deficiency in pregnancy outcome and neonatal survival and in the modulation of T cell differentiation in murine diabetic pregnancy and their offspring. Pregnant wild-type (WT) and PPAR alpha-null mice of C57BL/6J genetic background were rendered diabetic by five low doses of streptozotocin. We observed that, in the absence of diabetes, PPAR alpha deficiency resulted in an increase in abortion rate, i.e. 0% in WT mice vs. 20% in PPAR alpha-null mice [odds ratio (OR) = 14.33; P = 0.013]. Under diabetic conditions, the abortion rate was enhanced, i.e. 8.3% in WT mice vs. 50% in PPAR alpha-null mice (OR = 4.2…
Platelet, Not Endothelial, P-Selectin Expression Contributes to Generation of Immunity in Cutaneous Contact Hypersensitivity
2010
Leukocyte extravasation is a prerequisite for host defense and autoimmunity alike. Detailed understanding of the tightly controlled and overlapping sequences of leukocyte extravasation might aid development of novel therapeutic strategies. Leukocyte extravasation is initiated by interaction of selectins with appropriate carbohydrate ligands. Lack of P-selectin expression leads to decreased contact hypersensitivity responses. Yet, it remains unclear if this is due to inhibition of leukocyte extravasation to the skin or due to interference with initial immune activation in lymph nodes. In line with previous data, we here report a decreased contact hypersensitivity response, induced by 2,4,-di…
The Drainage System of the Paranasal Sinuses: A Review with Possible Implications for Balloon Catheter Dilation
2011
Background Intersinus connections and accessory ostia of the maxillary sinus are well known to rhinologic surgeons but are less known for the remaining paranasal sinuses. Probing and dilatation of the natural ostia of diseased sinuses is being popularized currently by the clinical value of balloon catheter dilation (BCD). Although short-term high success rates with treatment of the dilated ostia/duct have been reported with this technique, the potential impact of fractures of adjacent bony septae on accessory sinus ostia, on mucosally lined surfaces, and on intersinus drainage pathways still has not been considered. The aim of this study was to review the literature on accessory sinus ostia…
The diabetic ketoacidosis
2014
The Diabetic Ketoacidosis (DKA) is still today a medical emergency in pediatrics. Despite the latest great sensibilization of the population and the doctors, the risk of DKA has not yet been eliminated and this pathology is still occurring in 25 to 40% of diabetes onset cases, in already diagnosed patients with poor compliance (10%), in patients undergoing acute medical or surgical events or in patients in Continuous Subcoutaneous Insulin Therapy (CSII). In toddlers (0-3 years) it is twice more frequent than in the following ages and is characterized by the presence of more serious clinical dehydratation (>10%) and neurological signs (obnubilation 40%). The other category at risk is represe…
Osteoporosis, densidad mineral ósea y complejo CKD-MBD (I): consideraciones diagnósticas
2018
Resumen: Osteoporosis (OP) y enfermedad renal crónica (ERC) influyen de manera independiente en la salud ósea y cardiovascular. Un número significativo de pacientes con ERC, especialmente desde estadios 3a a 5D, presentan una disminución significativa de la densidad mineral ósea condicionando un alto riesgo de fractura y un incremento importante de la morbimortalidad asociada. Independientemente de la OP clásica asociada a edad y/o sexo, las propiedades mecánicas del hueso se encuentran afectadas adicionalmente por factores intrínsecos a la ERC («OP urémica»). En la primera parte de esta revisión, analizaremos conceptos generales sobre densidad mineral ósea, OP y fracturas, en gran parte in…
Incidence and clinical importance of perioperative histamine release: randomised study of volume loading and antihistamines after induction of anaest…
1994
Although histamine release is recognised as a common event during anaesthesia and surgery, few clinicians judge the resultant cardiorespiratory disturbances serious enough to warrant prophylaxis with antihistamines. We have assessed the incidence and importance of histamine release in a randomised 2 x 2 factorial study. 240 patients representing a routine throughput of major general surgery were studied during a standardised induction of anaesthesia and preoperative loading of the circulation with either Ringer solution or Haemaccel-35, with or without antihistamine prophylaxis with dimetindene (H1) plus cimetidine (H2). Cardiorespiratory disturbances were graded as detectable, clinically r…
Flat Panel Computed Tomography Pooled Blood Volume and Infarct Prediction in Endovascular Stroke Treatment
2019
Background and Purpose— Patients with large-vessel stroke frequently need to be transferred to comprehensive stroke centers for endovascular treatment. An update of physiological perfusion parameters and stroke progression on arrival is desirable. We examined the reliability of preinterventional pooled blood volume (PBV)-maps acquired by flat-panel detector computed tomography (CT) in the interventional angiography suite. Methods— The volumes of preinterventional perfusion deficit in flat-panel detector CT-PBV source images were compared with final infarct volume on follow-up multislice-CT after endovascular treatment of 29 consecutive patients with occlusion of the middle cerebral artery …
Revascularisation of a Giant Coronary Artery Aneurysm in Suspected Incomplete Kawasaki-Disease
2006
Kawasaki disease leads to typical vascular complications in up to 20 % of untreated cases. We describe a 47-year-old patient with coronary vessel disease, involving the right coronary artery with a huge aneurysmatic dilatation, suspicious for an incomplete form of Kawasaki disease. We found little information about the surgical treatment and postoperative course of this disease in adults. Typically, these infrequent patients present with acute myocardial infarction and require interdisciplinary decision-making.
CD133 expression in placenta chorioangioma presenting as a giant asymptomatic mass
2021
Background: Placental chorioangioma is the most common benign non-trophoblastic neoplasm of the placenta. Its clinical relevance lies in the size of the tumor since larger masses cause pregnancy complications, including an unfavorable neonatal outcome. Case presentation: We report the case of a 34-year-old second gravida and nullipara at the 35th week of gestation, admitted to the gynecological department for antibiotic-resistant fever. The cardiotocography performed during hospitalization showed an abnormal fetal pattern. A 2250 g newborn was delivered by cesarean section. No complications were observed during childbirth and postpartum was insignificant. On gross inspection a white fleshy …
