Prospective Validation of Facial Nerve Monitoring to Prevent Nerve Damage During Robotic Drilling
2019
Facial nerve damage has a detrimental effect on a patient's life, therefore safety mechanisms to ensure its preservation are essential during lateral skull base surgery. During robotic cochlear implantation a trajectory passing the facial nerve at <0.5 mm is needed. Recently a stimulation probe and nerve monitoring approach were developed and introduced clinically, however for patient safety no trajectory was drilled closer than 0.4 mm. Here we assess the performance of the nerve monitoring system at closer distances. In a sheep model eight trajectories were drilled to test the setup followed by 12 trajectories during which the ENT surgeon relied solely on the nerve monitoring system and…
THE METABOLIC SYNDROME IN HYPERTENSION
2019
The metabolic syndrome (MS) is currently considered to be a cluster of metabolic and cardiovascular risk factors including blood pressure elevation. A higher risk to develop hypertension in MS subjects with high-normal blood pressure has been observed and, when hypertension is established, seems to be what confers a higher cardiovascular risk on top of the risk induced by blood pressure elevation. Therefore, assessment of MS components can result in clinical utility strategy to manage hypertension based on individual risk. The main mechanisms for blood pressure elevation include overactivity of the sympathetic and the reninangiotensin system, abnormal renal sodium handling, and endothelial …
A new perspective on adolescent athletes’ transition into upper secondary school : A longitudinal mixed methods study protocol
2016
The challenge of combining elite sport and education into a dual career pathway remains to be a source of concern for many high-performance athletes. Previous research findings suggest that committed participation in both domains is highly demanding and success in one pursuit often comes at the expense of the other. There are emergent studies, however, that argue for the beneficial and complementary nature of dual career pathways. Consequently, we emphasize the importance of understanding the processes underlying differences in the development of athletes’ life trajectories. This article presents a study protocol to explore new methodological and analytical approaches that may extend curren…
NeuronAlg: An Innovative Neuronal Computational Model for Immunofluorescence Image Segmentation
2023
Background: Image analysis applications in digital pathology include various methods for segmenting regions of interest. Their identification is one of the most complex steps and therefore of great interest for the study of robust methods that do not necessarily rely on a machine learning (ML) approach. Method: A fully automatic and optimized segmentation process for different datasets is a prerequisite for classifying and diagnosing indirect immunofluorescence (IIF) raw data. This study describes a deterministic computational neuroscience approach for identifying cells and nuclei. It is very different from the conventional neural network approaches but has an equivalent quantitative and qu…
SV40 transformed fibroblasts recognize the same 140 kD fibronectin chemotactic fragment as non-transformed cells
1985
SV40-virus-transformed human embryonal fibroblasts show an enhanced chemotactic response to the glycoprotein fibronectin. However, they recognize the same chemotactic active region as non-transformed fibroblasts. The result suggests that an enhancement of chemotaxis by fibroblasts which have been transformed with Simian Virus 40 is due not to the utilization of further chemotactic domains in the molecule, but to an increased sensitivity of the cells to the chemoattractant.

Audzēkņu instrumentspēles prasmju un ķermeņa darbības pilnveides mijsakarības trombona spēles mācību procesā mūzikas skolā
2015
Trombona spēles pedagoģija bieži vien izmanto paņēmienus un metodes, kas ir pretrunā ar cilvēka ķermeņa darbības fizioloģiskajiem principiem un var gan kavēt un ierobežot instrumentspēles prasmju attīstību, gan radīt kaitējumus mūziķa veselībai. Ārvalstu mūzikas pedagoģijas zinātniskajā literatūrā arvien lielāks uzsvars tiek likts uz cilvēka darbības psiholoģisko un fizioloģisko mehānismu un likumsakarību integrēšanu pedagoģiskajā procesā. Arī trombona spēles prasmju pilnveidi nepieciešams balstīt cilvēka ķermeņa darbības pamatprincipos. Mērķis: izpētīt trombona spēles prasmju pilnveides teorētiskos aspektus un izstrādāt ķermeņa darbības psihofizioloģiskajos pamatprincipos balstītu vingrinā…
