Histologic and histomorphometric assessment of eggshell-derived bone graft substitutes on bone healing in rats
2013
Objective: The objective of this study was to histologically and histomorphometrically evaluate the efficacy of the new formulations of eggshell-derived calcium carbonate in rats. Study Design: The study was conducted on 30 adult male rats. Four standardized and circular intrabony defects were created in the both maxilla and mandibula of each animal. Three different graft materials were prepared as follows: 1) Material A: Eggshell-derived calcium carbonate combined with carrageenan gel, 2) Material B: Eggshell-derived calcium carbonate combined with xanthan gum gel, and 3) Material C: Eggshell-derived calcium carbonate powder. The right mandibular defect sites were grafted with Material A i…
Monitoring programme on cadmium, lead and mercury in fish and seafood from Valencia, Spain: levels and estimated weekly intake.
2008
The study was carried out to determine the current levels of mercury, cadmium, and lead in fish and seafood from the market of Comunitat Valenciana, Spain. Levels of total mercury ranged from 0.02 to 3.15 mg kg⁻¹ w.w. (average = 0.073 mg kg⁻¹ w.w.). Cadmium concentrations ranged from 0.003 to 0.66 mg kg⁻¹ w.w. (average = 0.27 mg kg⁻¹ w.w.) for seafood, and between 0.003 and 0.71 mg kg⁻¹ w.w. (average = 0.01 mg kg⁻¹ w.w.) for marine fish. Concerning lead, concentrations from 0.02 to 0.36 mg kg⁻¹ w.w (average = 0.04 mg kg⁻¹ w.w.) were found in fish, and from 0.02 to 1.02 mg kg⁻¹ w.w. in seafood (average = 0.147 mg kg⁻¹ w.w.). The levels found were, in general, lower than maximum levels propos…
Transient CD15-positive endothelial phenotype in the human placenta correlates with physiological and pathological fetoplacental immaturity
2013
Abstract Objective Placental growth and villous maturation are critical parameters of placental function at the end of pregnancy. A failure in these processes leads to the development of placental dysfunction, as well as fetal and neonatal mortality and morbidity. The aim of the study was to determine the relevant diagnostic markers associated with pathological placental development. Study design Forty tissue samples from normal placentas of different gestational age and 68 pathological term placentas with defective villous maturation (GDM, idiopathic IUFD, preeclamsia, HELLP syndrome) comprised the comparative immunohistochemical study (CD15, CD45 and CD34). Positive immunohistochemical re…
ProC® Global Assay in the Evaluation of Women with History of Severe Preeclampsia or HELLP Syndrome
2003
Preeclampsia/HELLP syndrome has been associated with a high incidence of defects in the protein C pathway and increased anticardiolipin-antibodies/lupus anticoagulants. It is also apparent that thrombophilia is responsible for other pregnancy complications, such as recurrent spontaneous abortion, fetal growth restriction, intrauterine fetal death, and abruptio placentae. ProC® Global is a new global clotting assay designed to evaluate the abnormalities in the protein C anticoagulant pathway. It is based on the ability of endogenous activated protein C, generated by activation of protein C by Protac®, to prolong an activated partial thromboplastin time. A total of 61 patients with a history…
Pregnancy-associated diseases are characterized by the composition of the systemic regulatory T cell (Treg) pool with distinct subsets of Tregs
2011
Dysregulations concerning the composition and function of regulatory T cells (T(regs)) are assumed to be involved in the pathophysiology of complicated pregnancies. We used six-colour flow cytometric analysis to demonstrate that the total CD4(+) CD127(low+/-) CD25(+) forkhead box protein 3 (FoxP3)(+) T(reg) cell pool contains four distinct T(reg) subsets: DR(high+) CD45RA(-), DR(low+) CD45RA(-), DR(-) CD45RA(-) T(regs) and naive DR(-) CD45RA(+) T(regs). During the normal course of pregnancy, the most prominent changes in the composition of the total T(reg) cell pool were observed between the 10th and 20th weeks of gestation, with a clear decrease in the percentage of DR(high+) CD45RA(-) and…
Laparoscopic treatment for esophageal achalasia: experience at a single center
2013
Background. Achalasia is a not frequent esophageal disorder cha- racterized by the absence of esophageal peristalsis and incomplete re- laxation of the lower esophageal sphincter (LES). Its cause is unknown. The aim of treatment is to improve the symptoms. We report the results of the treatment of this condition achieved in one center. Patients and methods. We conducted a retrospective study of pa- tients with esophageal achalasia. In the period 2010-2012 we observed 64 patients, of whom 19 were referred for medical treatment. Three of Introduction Achalasia is a not frequent esophageal motor disor- der that affects both the body of the esophagus and the lower esophageal sphincter (LES). It…
The Value of Scoring Achalasia: A Comparison of Current Systems and the Impact on Treatment–The Surgeon's Viewpoint
2007
Heller myotomy in patients with achalasia promises better long-term success than pneumatic dilation, especially in younger patients, and therefore has evolved as the primary treatment option. The aim of this study was to evaluate the impact of different disease-specific severity scores on achalasia treatment. Fifty consecutive patients undergoing pneumatic dilation (n = 25) or myotomy (n = 25) were assessed pre- and postinterventionally by clinical evaluation using the Eckardt Score, the Vantrappen Classification, and the Adams's Stages, as well as by radiologic and manometric studies and by subjective evaluation. The Eckardt Score and the Vantrappen Classification correlated significantly…
Acute liver failure and HELLP syndrome: A clinical case and literature review.
2021
Summary Background HELLP syndrome is a pregnancy-related liver disease associated with increased maternal and foetal mortality. In rare cases, it can lead to the development of a subcapsular hepatic haematoma as well as its rupture. This rupture is life-threatening if not urgently treated. Method We describe a clinical case of HELLP syndrome involving a ruptured subcapsular liver haematoma and contextualise this with a literature overview. Clinical case A 39-year-old woman of 40 weeks’ gestation presented to her local Emergency Department with symptoms and serology classically associated with HELLP syndrome. However, she clinically deteriorated and developed a ruptured subcapsular haematoma…
L’immagine di Agatocle e l’arte dell’età di Agatocle
2013
La tradizione letteraria, spesso ostile, ci restituisce in termini assai nitidi un’immagine di Agatocle del tutto in linea con le tendenze eminenti nell’arte aulica del Primo Ellenismo. Il Siracusano risulta aver sfruttato con abilità e perspicacia i clichés dell’ideologia regale affermatasi tra i Diadochi e gli Epigoni, nei regni originatisi dalla divisione dell’impero di Alessandro, fondata sull’esaltazione delle virtù militari eccezionali e del carisma del re (degno emulo del grande Macedone), e del suo stile di vita “straordinario”, cui le grandi feste e i banchetti danno occasione di ostentare magnificenza e generosità, definendo altresì le nuove gerarchie sociali. Da un lato quindi il…
