SLC20A1 Is Involved in Urinary Tract and Urorectal Development

2020

Previous studies in developing Xenopus and zebrafish reported that the phosphate transporter slc20a1a is expressed in pronephric kidneys. The recent identification of SLC20A1 as a monoallelic candidate gene for cloacal exstrophy further suggests its involvement in the urinary tract and urorectal development. However, little is known of the functional role of SLC20A1 in urinary tract development. Here, we investigated this using morpholino oligonucleotide knockdown of the zebrafish ortholog slc20a1a. This caused kidney cysts and malformations of the cloaca. Moreover, in morphants we demonstrated dysfunctional voiding and hindgut opening defects mimicking imperforate anus in human cloacal exs…

The Challenges of the European Anorectal Malformations-Net Registry

2015

Item does not contain fulltext Anorectal malformations (ARM) have a low prevalence, patients need specialized surgical care, and in many cases, patients born with ARM even need life-long aftercare. Due to its low prevalence most patients are still treated in low-volume pediatric surgical centers without any adequate monitoring of the outcome. Data on prevalence, comparison of different surgical techniques, and prospective outcome measurements are still scarce and difficult to interpret. In 2010, a consortium was founded (ARM-Net consortium) including several European pediatric surgical centers to collaborate more in research and share knowledge on ARM. One of the structures started by the c…

The Qualification of Outcome after Cervical Spine Surgery by Patients Compared to the Neck Disability Index

2016

Contains fulltext : 168196.PDF (Publisher’s version ) (Open Access) OBJECTIVE: The Neck Disability Index (NDI) is a patient self-assessed outcome measurement tool to assess disability, and that is frequently used to evaluate the effects of the treatment of neck-related problems. In individualized medicine it is mandatory that patients can interpret data in order to choose a treatment. A change of NDI or an absolute NDI is generally meaningless to a patient. Therefore, a correlation between the qualification of the clinical situation rated by the patient and the NDI score was evaluated. METHODS: Patients who completed an NDI after anterior surgery because of symptomatic single level degenera…

Association of Gestational Weight Gain With Adverse Maternal and Infant Outcomes

2019

Importance: Both low and high gestational weight gain have been associated with adverse maternal and infant outcomes, but optimal gestational weight gain remains uncertain and not well defined for all prepregnancy weight ranges. Objectives: To examine the association of ranges of gestational weight gain with risk of adverse maternal and infant outcomes and estimate optimal gestational weight gain ranges across prepregnancy body mass index categories. Design, setting, and participants: Individual participant-level meta-analysis using data from 196 670 participants within 25 cohort studies from Europe and North America (main study sample). Optimal gestational weight gain ranges were estimated…

Obtaining mesenchymal stem cells from adipose tissue of murine origin: Experimental study

2015

Stem cells have a key role in regenerative medicine and tissue engineering. Although not immortal, they are able to expand manyfold in culture retaining at the same time their growth and multilineage potential. They also show a migratory capacity when transplanted systemically in animal model with injuries. Thanks to their properties and their plasticity stem cells are of great importance since they can be used as a tool for repair damaged tissues and organs. Mesenchymal stem cells, in particular, have the ability to differentiate into lineages of mesodermal tissues, such as skeletal muscle, bone, tendons, cartilage, and fat under appropriate culturing conditions. Recent evidence suggest th…

On the Interaction between 1D Materials and Living Cells

2020

One-dimensional (1D) materials allow for cutting-edge applications in biology, such as single-cell bioelectronics investigations, stimulation of the cellular membrane or the cytosol, cellular capture, tissue regeneration, antibacterial action, traction force investigation, and cellular lysis among others. The extraordinary development of this research field in the last ten years has been promoted by the possibility to engineer new classes of biointerfaces that integrate 1D materials as tools to trigger reconfigurable stimuli/probes at the sub-cellular resolution, mimicking the in vivo protein fibres organization of the extracellular matrix. After a brief overview of the theoretical models r…

Largest neurosurgical social media group and its impact on communication and research

2022

Item does not contain fulltext BACKGROUND: The use of social media to communicate and disseminate knowledge has increased exponentially, especially in the field of neurosurgery. 'Neurosurgery cocktail' (NC) was developed by a group of young neurosurgeons as a means of sharing didactic materials and clinical experiences via social media. It connects 35.000 neurosurgeons worldwide on multiple platforms, primarily Facebook and Twitter. Given the rising utilization of social media in neurosurgery, the popularity of NC has also increased since its inception. In this study, the authors surveyed the social media analytics of NC for both Facebook and Twitter. Besides, we reviewed the literature on …

Complement proteins regulating macrophage polarisation on biomaterials

2019

[EN] One of the events occurring when a biomaterial is implanted in an host is the protein deposition onto its surface, which might regulate cell responses. When a biomaterial displays a compromised biocompatibility, distinct complement pathways can be activated to produce a foreign body reaction. In this article, we have designed different types of biomaterial surfaces to study the inflammation process. Here, we used different concentrations of (3-glycidoxypropyl)-trimethoxysilane (GPTMS), an organically-modified alkoxysilane as a precursor for the synthesis of various types of sol-gel materials functionalizing coatings for titanium implants to regulate biological responses. Our results sh…
