Protection from fishing improves body growth of an exploited species

2022

Hunting and fishing are often size-selective, which favours slow body growth. In addition, fast growth rate has been shown to be positively correlated with behavioural traits that increase encounter rates and catchability in passive fishing gears such as baited traps. This harvest-induced selection should be effectively eliminated in no-take marine-protected areas (MPAs) unless strong density dependence results in reduced growth rates. We compared body growth of European lobster ( Homarus gammarus ) between three MPAs and three fished areas. After 14 years of protection from intensive, size-selective lobster fisheries, the densities in MPAs have increased considerably, and we demonstrate t…

Critical Assessments of the Potential for Integrating Renewable Energy into Isolated Grids on Vietnamese Islands: The Case of the An-Binh Grid

2023

Renewable electricity for off-grid areas is widely seen as one of the top choices in supporting local economic development in most countries, and so is Vietnam. Over the years, many isolated networks using renewable energy sources have been deployed for off-grid areas in Vietnam. However, the use of these energy sources in Vietnam’s isolated networks is still facing many challenges due to its infancy here. The issues of reliability and vulnerability of these networks are not given the expected attention. Another challenge is that the issues of the operational security of these systems could also be negatively affected by the variable nature of renewable sources, including static and dynamic…

Klotho urinario determinado por ELISA como biomarcador precoz de fracaso renal agudo en pacientes sometidos a cirugía cardiaca o angiografía coronaria

2015

ResumenIntroducción y objetivos: El fracaso renal agudo (FRA) es una complicación frecuente tras la cirugía cardiaca y las intervenciones percutáneas coronarias cuya aparición empeora el pronóstico de manera marcada. En los últimos años se han identificado nuevos biomarcadores precoces de FRA, pero aún quedan muchos aspectos importantes por resolver. Klotho es una proteína pleiotrópica que actúa como un factor paracrino y endocrino en múltiples órganos. En diversos modelos animales de FRA se ha demostrado niveles disminuidos de Klotho renal. No se ha publicado ningún estudio en el que se haya probado Klotho como marcador precoz de FRA en humanos. El objetivo de este trabajo es investigar la…

Telehealth in Urology: A Systematic Review of the Literature. How Much Can Telemedicine Be Useful During and After the COVID-19 Pandemic?

2020

Context Coronavirus disease 2019 (COVID-19) pandemic has caused increased interest in the application of telehealth to provide care without exposing patients and physicians to the risk of contagion. The urological literature on the topic is sparse. Objective To perform a systematic review of the literature and evaluate all the available studies on urological applications of telehealth. Evidence acquisition After registration on PROSPERO, we searched PubMed and Scopus databases to collect any kind of studies evaluating any telehealth interventions in any urological conditions. The National Toxicology Program/Office of Health Assessment and Translation Risk of Bias Rating Tool for Human and A…

Renal and hepatic integrity in long-term sevoflurane sedation using the anesthetic conserving device: A comparison with intravenous propofol sedation…

2015

Abstract Introduction Critically ill patients are sedated with intravenous agents because the use of inhaled agents is limited by their potential risk of toxicity. Increasing levels of inorganic fluorides after the metabolism of these agents have been considered potentially nephrotoxic. However, hepatic involvement after prolonged administration of sevoflurane has not yet been studied. The present study evaluated the potential renal and hepatic toxicity caused by prolonged administration (72 h) of sevoflurane. Methods For this experimental, prospective, randomized, controlled trial, 22 Landrace × Large-White female pigs were randomly assigned to two groups: intravenous propofol (P) or inhal…

Kynurenine and Neopterin in Chronic Glomerulonephritis

1999

The results of our clinical observations of 102 patients with chronic glomerulonephritis with normal renal function have shown that hyperkynureninemia in 22,5% of patients develops in cases of pyridoxal-5-phosphate deficiency (hyperkynureninemia after peroral L-tryptophan load), but in 14,8% of patients through the stimulation of the cellular immune system (hyperkynureninemia at fasting state, increase of serum neopterin concentration). In all 20 patients with chronic renal failure hyperkynureninemia develops due to decreased renal function (increased serum kynurenine, neopterin and creatinine concentrations). Therefore, L-tryptophan peroral loading test with the determination of serum conc…

256 Functional analysis of elective nephron-sparing surgery versus radical nephrectomy for renal tumors larger than 4 cm

2012

Objective To preserve renal function, nephron sparing surgery (NSS) for renal tumors should be performed. Little is known about perioperative morbidity and long-term functional outcome of patients after elective NSS compared with radical nephrectomy (RN) in renal tumors >4 cm. Materials and Methods Eight-hundred twenty-nine patients were treated with either RN (n = 641) or NSS (n = 188) for renal tumors >4 cm. After pairing the cohort for age, grading, TNM, size, gender, and preoperative renal function and excluding patients with imperative indication and metastases, 247 patients remained for functional analysis. Serum creatinine (SCr) values were used to estimate glomerular filtration rate…

Clinical pathways for urology patients during the COVID-19 pandemic

2020

The public health emergency caused by the Coronavirus Disease 2019 (COVID-19) pandemic has resulted in a significant reallocation of health resources with a consequent reorganization of the clinical activities also in several urological centers. A panel of Italian urologists has agreed on a set of recommendations on pathways of pre-, intra- and post-operative care for urological patients undergoing urgent procedures or non-deferrable oncological interventions during the COVID-19 pandemic. Simplification of the diagnostic and staging pathway has to be prioritized in order to reduce hospital visits and consequently the risk of contagion. In absence of strict uniform regulations that impose th…
