Adrenal cysts – a rare entity

Nádia Mourinho Bala , Raposo Nuno , Sílvia Guerra , José Maria Aragüés , Valadas Cristina

IntroductionAdrenal cyst lesions are uncommon and only a few large series have been reported. The pathogenesis is unclear. Currently, adrenal cystic lesions are categorized into endothelial cysts, pseudocysts, epithelial cysts and parasitic cysts. In most cases they are found incidentally in asymptomatic patients or in patients with non-specific gastrointestinal symptoms. We describe three cases of adrenal cysts.Case report<p c...

Mitochondrial uncoupling proteins (UCPs) regulate the mitochondrial activity of human sertoli cells

Carrageta David F. , Freire-Brito Lais , Monteiro Bruno S. , Guerra-Carvalho Barbara , Bernardino Raquel L. , Oliveira Pedro F. , Monteiro Mariana P. , Alves Marco G.

Introduction: Mitochondrial uncoupling proteins (UCPs) are channel proteins present in the mitochondrial inner membrane which are responsible for the transport of protons between the mitochondrial intermembrane space and the matrix. Currently, six UCP homologues had been identified (UCP1-6). UCPs are major regulators of reactive oxygen species (ROS) production, general cellular redox state and metabolism. UCPs also exhibit specific functions, such as UCP1 and thermogenesis or ...

High-fat diet promotes 3’mt-tiRNA-Met epididymosome enrichment which correlates to lower spermatozoa mitochondrial translation

Pereira Sara C. , Freire-Brito Lais , Guerra-Carvalho Barbara , Carrageta David F. , Bernardino Raquel , Crisostomo Luis , Terzo Simona , Monteiro Mariana P. , Oliveira Pedro F. , Allegra Mario , Alves Marco

Metabolic and endocrine dysregulation induced by high-fat diet (HFD) can lead to decreased male fertility potential and have a negative impact on the offspring’s metabolic health. Small non-coding RNAs (sncRNAs) were proposed as being potential mediators of metabolic queues across transgenerational inheritance. During development and epidydimal transit, spermatozoa become enriched with tRNA-derived stress-induced RNAs (tiRNAs). This sncRNAs class appears to be particularl...

In vitro exposure to the endocrine disruptor atrazine induces a pro-oxidant state and modulates mouse Sertoli cells metabolic support of spermatogenesis

Gomes-Andrade Daniela , Guerra-Carvalho Barbara , Carrageta David F. , Bernardino Raquel L. , Oliveira Pedro F. , de Lourdes Pereira Maria , Alves Marco G.

Introduction: Atrazine is one of the most widely used pesticides worldwide and a common contaminant in human drinking water. Atrazine is also a potent endocrine disruptor capable of causing a variety of negative health outcomes, including decreased testosterone production and infertility. Although harmful effects of atrazine on male reproductive health have been reported, little is known about its molecular mechanisms. Within the seminiferous tubules, Sertoli cells are respons...

Cytotoxic activity of plant extracts from Brazilian biome in prostate cancer cell lines

Cardoso Sarah , Andrade Matheus , Cunha Vinicius , Silva Cristian , Rodrigues Patricia , Leao Mayra , Fagg Christopher , Guerra Eliete , Neves Francisco , Simeoni Luiz , Silveira Damaris , Lofrano-Porto Adriana

Introduction: Prostate cancer is a public health problem worldwide. The cure is unlikely and therapeutic alternatives are limited. The Brazilian biodiversity represents a huge source of potential discovery of new drugs derived from plants. We therefore aimed to conduct a biomonitoring chemical study of plant extracts from Pouteria sp. previously shown to be cytotoxic in androgen-sensitive (LNCaP) and androgen-resistant (PC3) human prostate cancer cell lines.<p cla...

Patients with new onset diabetes after liver transplantation have higher sclerostin levels that tend to decrease after an oral glucose tolerance test

Diaz-Guerra Guillermo Martinez , Miguel Gonzalo Allo , Ramos Mercedes Aramendi , Librizzi Soledad , Iglesias Sonsoles Guadalix , Fernandez Elena Garcia , Carranza Federico Hawkins

Introduction: Decreased bone formation has been proposed as a mechanism involved in the higher risk of fractures in diabetic patients. Some clinical studies have found that sclerostin (SCL, a negative regulator of bone formation) is increased in diabetic patients. However, there is no information about the relationship between SCL and new onset diabetes after transplantation (NODAT). The aim of our study is to evaluate serum SCL levels in a cohort of patients with liver transp...

Exposure to phenolic compounds (Bisphenol A and Methyl Paraben) in pregnancy and its relationship with gestational diabetes mellitus, insulin homeostasis and pancreatic beta cell function

Serrano Joaquin , Picó-Alfonso Antonio , Fernández Mariana F , Pedro Arrebola Juan , Alfayate-Guerra Rocio , Teresa López Maria , Moreno-Perez Oscar

Objectives: The effect of exposure to endocrine disruptors (exogenous chemical compounds that interfere with hormonal homeostasis), such as Bisphenol A (BPA) and Methyl Paraben (MPB), on gestational diabetes mellitus (GDM) has only been investigated in a small number of studies, with inconclusive results. Our objective was to investigate the association between concentrations of BPA and MPB in urine and the presence of DMG, insulin sensitivity and function of beta cells in a c...

Prevalence of hypovitaminosis D in adult patients with hypopituitarism

Di Somma C. , Esposito R. , Savanelli M. , Scarano E. , Brunelli V. , Contaldi P\. , Rubino M. , Guerra E. , Vuolo L. , Savastano S. , Colao A.

Introduction: Italy is considered a country with high prevalence of 25 OH vitamin D deficiency. Changes in vitamin D serum levels were linked with the onset and progression of several diseases, including osteoporosis and cardiovascular diseases. The hypopituitary patients show several comorbidities like cardiovascular diseases and osteoporosis.Purpose: To evaluate the prevalence of vitamin D deficiency in hypopituitary patients.Pat...

Providing good information, exchanging expertise and stimulating clinical discussions are usually main goals when structuring academic services. Nowadays, especially in large countries with social/economic differences between regions, such as Brazil, telemedicine and telehealth are resources with main strategic importance in a country’s Public Health System. Since its creation, RUTE network (Rede Universitária de Telemedicina, supported by brazilian Ministry of Scien...
