Effects of cadmium on the biochemical composition of the freshwater crayfishProcambarus clarkii (Girard, 1852)
1991
Lake Albufera of Valencia (Spain) and the surrounding rice field waters are subjected to very heavy loads of sewage and toxic residues. Among these residues include heavy metals which have been deposited from the many urban and waste waters in this area. The American red crayfish, Procambarus clarkii from Albufera Lake has high resistance to heavy metals. The authors have also found that P. clarkii shows a high capacity for cadmium accumulation in experimental conditions and natural conditions since crayfish collected in this area contained considerable amounts of cadmium in several tissues even after 15 days of depuration in clean water. Since the physiological changes that take place when…
No influence of oxygen levels on pathogenesis and virus shedding in Salmonid alphavirus (SAV)-challenged Atlantic salmon (Salmo salar L.)
2010
Abstract Background For more than three decades, diseases caused by salmonid alphaviruses (SAV) have become a major problem of increasing economic importance in the European fish-farming industry. However, experimental infection trials with SAV result in low or no mortality i.e very different from most field outbreaks of pancreas disease (PD). This probably reflects the difficulties in reproducing complex biotic and abiotic field conditions in the laboratory. In this study we looked at the relationship between SAV-infection in salmon and sub-lethal environmental hypoxia as a result of reduced flow-through in tank systems. Results The experiment demonstrated that constant reduced oxygen leve…
Pancreatic Extracts for the Treatment of Diabetes (1889-1914): Acomatol.
2019
Background Historical review on the early development of organotherapy for diabetes [pancreatic extracts (PE)] and its relationship with the social and political circumstances. Areas of uncertainty The diagnosis of diabetes relied only in the presence of glycosuria and cardinal symptoms. Blood glucose determinations were not regularly available, requiring large volumes for sampling. Micromethods for glycemia were developed just in the last years of the investigated period. Hypoglycemia remains undiscovered. Isolation and purification of PE were difficult tasks due to the unknown chemical structure of the antidiabetic hormone. Data sources (1) Berliner Medizinhistoriches Museum der Charite (…
Wharton’s Jelly Mesenchymal Stem Cells as Candidates for Beta Cells Regeneration: Extending the Differentiative and Immunomodulatory Benefits of Adul…
2010
Mesenchymal stem cells (MSC) are uniquely capable of crossing germinative layers borders (i.e. are able to differentiate towards ectoderm-, mesoderm- and endoderm-derived cytotypes) and are viewed as promising cells for regenerative medicine approaches in several diseases. Type I diabetes therapy should potentially benefit from such differentiated cells: the search for alternatives to organ/islet transplantation strategies via stem cells differentiation is an ongoing task, significant goals having been achieved in most experimental settings (e.g. insulin production and euglycaemia restoration), though caution is still needed to ensure safe and durable effects in vivo. MSC are obtainable in …
Valor de la proteína C reactiva en la detección de la necrosis en la pancreatitis aguda
2003
Objetivos Valorar la utilidad de la proteina C reactiva (PCR) en la deteccion de la necrosis en la pancreatitis aguda y precisar el mejor nivel de corte de la PCR para esta finalidad. Material y metodos Se incluyeron, de forma retrospectiva, 157 pacientes con pancreatitis aguda a los que se habia efectuado una tomografia computarizada (TC) con contraste intravenoso, entre las 72 h y el octavo dia del inicio de la sintomatologia, y determinado el valor de la PCR en el suero por nefelometria a partir de las 24 h del comienzo del dolor. Resultados En total, fueron incluidos 94 varones y 63 mujeres, con una media de edad de 61 anos (limites, 15-96 anos). La etiologia de la pancreatitis fue: lit…

95. Frühindikation der akuten Pankreatitis: Operativ
1978
Das Versagen der konservativen Therapie bei den schweren Verlaufsformen der akuten Pankreatitis, denen eine hamorrhagisch-nekrotisie-rende Entzundung zugrundeliegt, ist einer der Grunde fur ihre operative Behandlung mit dem Ziel, die Nekrosen zu entfernen. Bei den partiellen Nekrosen ging die Letalitat unter operativer Therapie erheblich zuruck, bei den subtotalen und totalen Nekrosen sind erst Einzelerfolge zu verzeichnen. Hier gilt die Forderung nach fruherer Erkennung und ℛorzeitiger Operation”, d. h. vor Auftreten lebensbedrohlicher Komplikationen.
Wertigkeit der pr�operativen Diagnostik zur Beurteilung der Tumorausdehnung bei ductalen Pankreascarcinomen
1990
Fur die Therapieplanung beim Pankreascarcinom kann die Wertigkeit der praope-rativen Beurteilung der Tumorausdehnng von Bedeutung sein. Bei 449 Patienten wurde retrospektiv und bei 35 Patienten prospektiv die Wertigkeit der praoperativen Diagnostik in der Beurteilung dieser Fragestellung uberpruft. Dabei zeigte sich, das nur die Kombination von Angiographie und Computertomographie eine Aussage zur Gefasinfiltration mit einer Treffsicherheit von 90% ermoglicht. Lebermetastasen wurden retrospektiv in 80% und prospektiv in 66,7% (Sonographie) bzw. 58,3% (Computertomographie) bei einer Spezifitat von 86,9% bzw. 91,3% erkannt. Diese Ergebnisse bestatigen das bisherige Therapiekonzept, das nur be…
Studies of malformation syndromes of man XIB: the cerebro-hepato-renal syndrome of zellweger: Comparative pathology
1976
A study of 11 autopsied cases of the cerebro-hepato-renal syndrome of Zellweger (ZS) is reported. All cases had severe, persistent congenital hypotonia, hepatic lobular disarray, renal cortical cysts and pulmonary hypoplasia. Many had cardiovascular malformations, hepatomegaly, cerebral cortical gyral maldevelopment and pancreatic islet hyperplasia. Additional, less frequent findings are delineated. Results of iron content studies of hepatic and renal tissues are related to age of survival and possible development of fibrosis.
Organ Recovery Procedure in Donation After Controlled Circulatory Death with Normothermic Regional Perfusion: State of the Art
2020
The global shortage of organ donors will not be resolved solely by relying on donation after brain death. Expansion to use of donation after controlled circulatory death will be needed to address the shortfall of organs for transplantation. The processes of warm ischemia threaten the viability of organs obtained after controlled circulatory death, but these can be minimized by well-organized donation pathways and new techniques of in situ organ preservation, such as normothermic regional perfusion. The use of extracorporeal membrane oxygenation (ECMO) devices for normothermic regional perfusion in liver transplantation can help reduce rates of biliary complications, ischemic type biliary le…
