  abstract  = {Mit modernen nicht invasiven bildgebenden Verfahren lassen sich anhand der Fundusfotografie bzw. der optischen Verfilmung Aspekte der funktionellen und strukturellen retinalen Gef{\"a}ßver{\"a}nderungen objektiv untersuchen. Der Zustand und das Verhalten retinaler Gef{\"a}ße beeinflussen im pr{\"a}-, post- und kapillaren Bereich den Blutfluss und str{\"o}mungsbedingte Stoffwechselverh{\"a}ltnisse passiv und aktiv {\"u}ber den Gef{\"a}ßdurchmesser. Retinale Gef{\"a}ße gleichen von Aufbau und Funktion den zerebralen Gef{\"a}ßen und spiegeln den Zustand der Mikrozirkulation wider. Mithilfe von aus den Gef{\"a}ßweiten berechneten Biomarkern soll eine Aussage {\"u}ber die Prognose von systemischen vaskul{\"a}r bedingten Erkrankungen getroffen werden. Die statische retinale Gef{\"a}ßanalyse befasst sich mit der Untersuchung des Zustandes der pr{\"a}- und postkapillaren Gef{\"a}ßdurchmesser der retinalen Mikrozirkulation anhand einer optischen Fundusaufnahme. Bei der dynamischen retinalen Gef{\"a}ßanalyse wird der L{\"a}ngsschnitt eines retinalen Gef{\"a}ßes nicht invasiv funktionell und strukturell {\"u}ber einen Zeitraum vor, w{\"a}hrend und nach einer spezifischen vaskul{\"a}ren Stimulation untersucht. Die genaue Methodologie der Auswertung und die Bezeichnung der Parameter variieren bei unterschiedlichen Ans{\"a}tzen. Mittels retinaler Gef{\"a}ßanalyse wurden bislang mehrere klinische Querschnitts- und Interventionsstudien in der Augenheilkunde und anderen Fachgebieten, inkl. Kardiologie, Neurologie, Neurochirurgie, Nephrologie, Gyn{\"a}kologie, Sportmedizin, Diabetologie, Hypertensiologie usw. durchgef{\"u}hrt. Mit der statischen retinalen Gef{\"a}ßanalyse steht eine kosteng{\"u}nstige, reproduzierbare, nicht invasive Screeningtechnik zur Verf{\"u}gung, um eine prognostische Aussage {\"u}ber die Gef{\"a}ßgesundheit eines individuellen Patienten zu treffen. Die dynamische retinale Gef{\"a}ßanalyse besitzt ein weiteres diagnostisches Anwendungsspektrum als die statische, da sie das Verhalten retinaler Gef{\"a}ße zeitkontinuierlich untersucht. Die Evaluation vaskul{\"a}rer Erkrankungen sowie zerebro- bzw. kardiovaskul{\"a}rer Morbidit{\"a}t und Mortalit{\"a}t mittels mehrerer methodologischer Modalit{\"a}ten retinaler Gef{\"a}ßanalyse mit ihren jeweiligen quantitativen Biomarkern bietet eine zukunftstr{\"a}chtige diagnostische Perspektive. Die interdisziplin{\"a}re klinische Anwendung dieser vaskul{\"a}ren Biomarker gewinnt zunehmend an Bedeutung, sowohl in der Augenheilkunde als auch in anderen Fachgebieten.},

  abstract  = {Impaired cerebral autoregulation and neurovascular coupling (NVC) contribute to delayed cerebral ischemia after subarachnoid hemorrhage (SAH). Retinal vessel analysis (RVA) allows non-invasive assessment of vessel dimension and NVC hereby demonstrating a predictive value in the context of various neurovascular diseases. Using RVA as a translational approach, we aimed to assess the retinal vessels in patients with SAH. RVA was performed prospectively in 24 patients with acute SAH (group A: day 5-14), in 11 patients 3 months after ictus (group B: day 90 ± 35), and in 35 age-matched healthy controls (group C). Data was acquired using a Retinal Vessel Analyzer (Imedos Systems UG, Jena) for examination of retinal vessel dimension and NVC using flicker-light excitation. Diameter of retinal vessels—central retinal arteriolar and venular equivalent—was significantly reduced in the acute phase (p < 0.001) with gradual improvement in group B (p < 0.05). Arterial NVC of group A was significantly impaired with diminished dilatation (p < 0.001) and reduced area under the curve (p < 0.01) when compared to group C. Group B showed persistent prolonged latency of arterial dilation (p < 0.05). Venous NVC was significantly delayed after SAH compared to group C (A p < 0.001; B p < 0.05). To our knowledge, this is the first clinical study to document retinal vasoconstriction and impairment of NVC in patients with SAH. Using non-invasive RVA as a translational approach, characteristic patterns of compromise were detected for the arterial and venous compartment of the neurovascular unit in a time-dependent fashion. Recruitment will continue to facilitate a correlation analysis with clinical course and outcome.},

  abstract  = {The objective of this paper is to present our findings on the biomechanical aspects of the virgin passive anisotropic hyperelasticity of the porcine colon based on equibiaxial tensile experiments. Firstly, the characterization of the intestine tissues is discussed for a nearly incompressible hyperelastic fiber-reinforced Holzapfel-Gasser-Ogden constitutive model in virgin passive loading conditions. The stability of the evaluated material parameters is checked for the polyconvexity of the adopted strain energy function using positive eigenvalue constraints of the Hessian matrix with MATLAB. The constitutive material description of the intestine with two collagen fibers in the submucosal and muscular layer each has been implemented in the FORTRAN platform of the commercial finite element software LS-DYNA, and two equibiaxial tensile simulations are presented to validate the results with the optical strain images obtained from the experiments. Furthermore, this paper also reviews the existing models of the active smooth muscle cells, but these models have not been computationally studied here. The review part shows that the constitutive models originally developed for the active contraction of skeletal muscle based on Hill's three-element model, Murphy's four-state cross-bridge chemical kinetic model and Huxley's sliding-filament hypothesis, which are mainly used for arteries, are appropriate for numerical contraction numerical analysis of the large intestine.},

  abstract  = {There is a growing body of evidence for the effects of vitamin D on intestinal host-microbiome interactions related to gut dysbiosis and bowel inflammation. This brief review highlights the potential links between vitamin D and gut health, emphasizing the role of vitamin D in microbiological and immunological mechanisms of inflammatory bowel diseases. A comprehensive literature search was carried out in PubMed and Google Scholar using combinations of keywords "vitamin D," "intestines," "gut microflora," "bowel inflammation". Only articles published in English and related to the study topic are included in the review. We discuss how vitamin D (a) modulates intestinal microbiome function, (b) controls antimicrobial peptide expression, and (c) has a protective effect on epithelial barriers in the gut mucosa. Vitamin D and its nuclear receptor (VDR) regulate intestinal barrier integrity, and control innate and adaptive immunity in the gut. Metabolites from the gut microbiota may also regulate expression of VDR, while vitamin D may influence the gut microbiota and exert anti-inflammatory and immune-modulating effects. The underlying mechanism of vitamin D in the pathogenesis of bowel diseases is not fully understood, but maintaining an optimal vitamin D status appears to be beneficial for gut health. Future studies will shed light on the molecular mechanisms through which vitamin D and VDR interactions affect intestinal mucosal immunity, pathogen invasion, symbiont colonization, and antimicrobial peptide expression.},
