Health behaviour in children and adolescents with type 1 diabetes compared to a representative reference population.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status.

Synergistic mutations in SLC3A1 and SLC7A9 leading to heterogeneous cystinuria phenotypes: pitfalls in the diagnostic workup.
Pediatr. Nephrol.
PUBLISHED: 03-17-2013
Show Abstract
Hide Abstract
Cystinuria is an inherited disorder of a renal tubular amino acid transporter and leads to increased cystine excretion with the risk of urinary stone formation. Phenotypical classification is based on urinary amino acid concentration as type I (silent), type non-I (hyper-excretors), mixed or untyped. Genotypic classification is based on mutations in SLC3A1 (type A) or SLC7A9 (type B).

Estrogen receptor alpha expression in podocytes mediates protection against apoptosis in-vitro and in-vivo.
PLoS ONE

Show Abstract
Hide Abstract
Epidemiological studies have demonstrated that women have a significantly better prognosis in chronic renal diseases compared to men. This suggests critical influences of gender hormones on glomerular structure and function. We examined potential direct protective effects of estradiol on podocytes.

The influence of gender and sexual hormones on incidence and outcome of chronic kidney disease.

Hide Abstract
It has long been known that the female sex is associated with a better clinical outcome in chronic renal diseases. Although many experimental, clinical, and epidemiological studies in adults have attempted to explain the difference in disease progression between females and males, a definitive understanding of the underlying mechanisms is still lacking. Hormone-modulating therapies are being increasingly used for various indications (such as post-menopausal hormone replacement, estrogen- or androgen-receptor antagonists for cancer therapy). Therefore, a deeper knowledge of the interaction between sexual hormones and progression of kidney disease is important, as hormone-modulating therapy for non-renal indication may influence both kidney structure and function. In addition, specific modulation of the sexual hormone system, such as the use of selective estrogen receptor modulators, may represent a therapeutic option for patients with renal diseases. Although conclusive data on this topic in the pediatric population are still lacking, the aim of this review is to familiarize pediatric nephrologists with gender-specific differences in renal physiology, pathophysiology, and the progression of kidney diseases. Experimental models that analyze the effects of sexual hormones on renal structure and function are discussed. It is hoped that this review will stimulate researchers to focus on pediatric studies that will provide a deeper insight into the interaction of gender hormones and the kidney both before and during puberty.

Liver fibrosis in recessive multicystic kidney diseases: transient elastography for early detection.
Pediatr. Nephrol.
PUBLISHED: 01-05-2011
Show Abstract
Hide Abstract
Cystic renal diseases are characterized by intrarenal cysts of different size and number. Further important diagnostic criteria include, e.g., liver fibrosis. The latter represents a significant cause of morbidity and mortality in autosomal-recessive polycystic kidney disease (ARPKD), whereas patients with autosomal-dominant polycystic kidney disease (ADPKD) can develop hepatic cysts without fibrosis. We report the use of transient elastography [FibroScan®, (FS)] for early and noninvasive detection of increased liver stiffness as marker of liver fibrosis. Compared with matched healthy controls, ADPKD patients (n?=?7) showed no significant difference in liver stiffness (5.3 kPa vs. 4.5 kPa; ns). ARPKD patients (n?=?7) had significantly increased median liver stiffness compared with controls (12.0 kPa vs. 4.5 kPa, p?=?0.002) and ADPKD patients (12.0 kPa vs. 5.3 kPa, p?=?0.002). Conventional ultrasound revealed evidence of liver fibrosis in only four of seven ARPKD patients (57%) compared with 100% detection by FS. Additional laboratory examinations showed no pathologic liver parameters. In conclusion, our data found FS to be a valuable, sensitive, and noninvasive new tool for early evaluation of liver fibrosis in cystic kidney diseases. This could facilitate diagnosis, monitoring, and management of liver involvement in ARPKD or any other cystic kidney disease.

Regulation of protein tyrosine kinases in tumour cells by the transcription factor Ets-1.
Int. J. Oncol.
PUBLISHED: 09-30-2009
Show Abstract
Hide Abstract
Tyrosine phosphorylation is one of the key covalent modifications that occurs in multicellular organisms as a result of intercellular communication. The family of tyrosine kinases (PTKs) are responsible for part of the cellular phosphorylation and are involved in a broad variety of cellular functions including differentiation, proliferation, migration, invasion, angiogenesis and survival under physiological as well as pathological conditions. Aberration in PTK signalling occurs in inflammatory diseases and diabetes, and aberrant expression can lead to benign proliferative conditions as well as to various forms of cancer. Indeed, more than 70% of the known oncogenes and proto-oncogenes involved in cancer code for PTKs. Therefore, these enzymes are now used as targets in the treatment of different tumours. Ets-1 is a transcription factor expressed in a number of human malignancies with demonstrated roles within both neoplastic cells and tumour stroma. These roles include stimulation of tumour cell proliferation and invasion as well as tumour angiogenesis. Database searches have revealed that ETS binding sites are present in several promoters of PTK-encoding genes. We investigated the role of Ets-1 in transcriptional regulation of a panel of 89 PTKs in epithelial HeLa tumour cells. In this study, HeLa cells stably overexpressing and underexpressing Ets-1 were used for real-time PCR analysis of all known human PTKs. The results suggest that Ets-1 is an essential transcription factor that cannot be substituted by other members of the ETS family. Transcription of most PTKs was found to be increased by Ets-1. In contrast Ets-1 seems to act as a transcriptional repressor of other PTKs. The data presented here underscore the importance of Ets-1 in tumour development and progression.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
