Aroclor 1254 inhibits the chemiluminescence response of peritoneal cavity cells from sharpsnout sea bream (Diplodus puntazzo)

2014

Chronic exposure to polychlorinated biphenyls (PCBs) affect the immune system of fish and could lead to a decreased disease resistance. The effects of Aroclor 1254, PCB mixtures, on the Diplodus puntazzo innate immunity were examined by assaying the zymosan stimulated chemiluminescence response (CL) of peritoneal cavity cells (PCCs) at various times (1, 24, 48 h and 1-4 weeks) from intraperitoneal injection of the xenobiotic (1 mg kg(-1) body weight). Controls were performed by assaying cells from medium-treated fish. Since the kinetic of the chemiluminescence response showed the highest peak at 25 min after the zymosan stimulation of the cells, the values found at that time were considered…

Efficacy of a bivalent vaccine against eel diseases caused by Vibrio vulnificus after its administration by four different routes

2003

Vulnivaccine, a vaccine against vibriosis caused by Vibrio vulnificus serovar E (formerly biotype 2), confers acceptable levels of protection to eels after its administration by prolonged immersion in three doses. Recently, a new pathogenic serovar, named serovar A, has been isolated from vaccinated eels in a Spanish freshwater eel farm. The main objective of this work was to design a bivalent vaccine, and to study its effectiveness against the two pathogenic serovars. With this aim, eels weighing around 20 g were immunised with the bivalent vaccine by oral and anal intubation, intraperitoneal injection (i.p.) and prolonged immersion. The overall results indicated that: (i) the new vaccine …

Use of tailored intraperitoneal ePTFE dual mesh in permagna inguinal hernia

2012

Here we report a case of a giant inguinoscrotal hernia in an elderly patients treated by means of an open positioning of intraperitoneal ePTFE dual mesh. In patients with giant inguinoscrotal hernia the forceful introduction of viscera in abdominal cavity and primary wall closure is burnened from respiratory complication, abdominal compartment syndrome, and defects in wound healing thus exposing the patients to further morbidity and mortality risk. The management of these patients is difficult because of the high occurrence of morbidity factors that affect the success on intervention independently of the technique of surgical repair. The tension- free technique we adopted consented us to ob…

USE OF INTRAPERITONEAL PTFE DUAL-MESH IN A GIANT INCISIONAL HERNIA AFTER RENAL TRANSPLANTATION: A CASE REPORT

2008

Objectives: We evaluated the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair of a giant incisional hernia by intraperitoneal PTFE dual mesh. Patients and methods: We report our experience about an incisional hernia in a 55 years male after renal transplantation treated with an intraperitoneal dual mesh prosthesis. The cause of incisional hernia was probably due to an urinoma for a total necrosis of distal graft ureter that needed to reopen in 2sd day post transplant with primary fascial approximation. Thirty days after transplantation we discovered a large incisional hernia that rapidly became monstrous with migration of o…

Species differences, influence of dose and application on biotransformation of phenol in fish.

1983

1. The metabolism of phenol in goldfish (Carassius auratus), rainbow trout (Salmo gairdneri) and goldenorfe ide (Leuciscus ideus melanotus) was compared. All three species produced phenyl sulphate, quinol sulphate and phenyl glucuronide. 2. The dose dependence of metabolism of phenol in goldfish was investigated. When the concn. of phenol was increased from 0.2 to 2 mg/l medium, that glucuronylated increased from 7 to 16% and that sulphated decreased from 63 to 47%. 3. The influence of mode of exposure on metabolism of phenol in goldfish was examined. Dietary exposure and uptake from medium was compared with i.p. injection. There was less metabolism in the order: dietary exposure greater th…

The effect of metals on condition and pathologies of European eel (Anguilla anguilla): in situ and laboratory experiments.

2011

Forty-nine wild eels (Anguilla anguilla) caught in the Albufera Lake (Spain), measuring 24.0-75.0 cm in length and 25.0-637.7 g in weight, were examined for metals (Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, Se and Zn), condition (CI and HSI indices), as well as for diseases (Anguillicola infestation; bacterial infections). Total metal load significantly increased in eel liver tissue parallel to total length and body weight (log), while silvering females (W(B) > 200 g; L ≥ 500 mm) exhibited the highest amounts of Co, Cu, Hg, Se and Zn. Diverse effects may be expected in these big eels due to long-term metal exposure. In fact, IMBI (individual mean (multi-metal) bioaccumulation index) and copper load (…

Estándares de calidad en la cirugía de carcinomatosis peritoneal de origen colorectal mediante citorreducción y quimioterapia intraperitoneal hiperte…

2020

El mayor conocimiento de la historia natural de la carcinomatosis peritoneal ha permitido su valoración como una progresión locorregional. Tras los trabajos publicados por Sugarbaker tanto a nivel quirúrgico, con la descripción de las técnicas de peritonectomía como a nivel farmacológico experimental para la aplicación de la quimioterapia intraperitoneal hipertérmica (HIPEC), se considera un tratamiento locorregional de la enfermedad confinada al abdomen. Así, una cirugía radical de citorreducción con extirpación de la enfermedad macroscópica y la aplicación posterior de HIPEC para control de la enfermedad microscópica residual, ha obtenido resultados muy superiores a la quimioterapia aisla…

Following traumatic brain injury (TBI) neuroinflammatory processes promote neuronal cell loss. Alpha-melanocyte-stimulating hormone (α-MSH) is a neuropeptide with immunomodulatory properties, which may offer neuroprotection. Due to short half-life and pigmentary side-effects of α-MSH, the C-terminal tripeptide α-MSH(11–13) may be an anti-inflammatory alternative. The present study investigated the mRNA concentrations of the precursor hormone proopiomelanocortin (POMC) and of melanocortin receptors 1 and 4 (MC1R/MC4R) in naive mice and 15 min, 6, 12, 24, and 48 h after controlled cortical impact (CCI). Regulation of POMC and MC4R expression did not change after trauma, while MC1R levels incr…

Elevated cortisol modulates hsp70 and hsp90 gene expression and protein in sea bass head kidney and isolated leukocytes

2012

In fish, interactions between Hsps and cortisol are involved in stress modulated physiological processes including innate immune responses. Cortisol exerts a role in the regulation of Hsps synthesis. Fish head kidney is a lymphomieloid and endocrine organ releasing cortisol, and it is the central organ for immune-endocrine interactions. In sea bass, cortisol intraperitoneal injection and in vitro treatment of head kidney cells show that inducible Hsp70 and Hsp90 are modulated by this hormone. However, an inverse relationship between mRNA expression (real-time PCR) and Hsp70 and Hsp90 protein levels (densitometric band analysis) was found. Time-course assays indicate a cortisol-mediated regu…

Biodistribution of Insulin-Nanogels in Mouse: A Preliminary Study for the Treatment of Alzheimer's Disease

2017

A growing body of evidence shows that Insulin, Insulin Receptor (IR) and IR signaling are involved in brain cognitive functions and their dysfunction is implicated in Alzheimer's disease (AD) neurodegeneration. Thus, administration of insulin could be a strategy for AD treatment. For this aim we have designed, synthesized and characterized a nanogel system (NG) that has been conjugated to insulin molecules (NG-In) to deliver the protein into the brain, as a tool for the development of a new therapy against AD. In our preclinical study in mice, intraperitoneal injection of fluorescent-labeled NG has allowed to determine the biodistribution of NG vs time in the whole body and its clearance th…
