  1. Artikel ; Online: Endothelial Cell-Pericyte Interactions in the Pathogenesis of Cerebral Cavernous Malformations (CCMs).

    Abstract Cerebral cavernous malformations (CCMs), consisting of multiple, dilated capillary channels formed by a single layer of endothelium and lacking parenchymal cells, are exclusively to the brain. Patients with inherited autosomal-dominant CCMs carry loss-of-function mutations in one of three genes: CCM1, CCM2, and CCM3. It is not known why CCM lesions are confined to brain vasculature despite the ubiquitous expression of CCM proteins in all tissues, and whether cell types other than endothelial cells (ECs) contribute to CCM lesion formation. The prevailing view is that the primary defects in CCMs in humans are EC-intrinsic, such that EC-specific deletion of any one of the three genes in mice results in similar CCM lesions. An unexpected finding is that Ccm3 deletion in pericytes (PCs) also induces CCM lesions. CCM3 deletion in ECs or PCs destabilizes PC-EC associations, highlighting the importance of these interactions in CCM formation.

    Abstract Cytochrome P450 monooxygenases (P450s) are considered nature's most versatile catalysts and play a crucial role in regio- and stereoselective oxidation reactions on a broad range of organic molecules. The oxyfunctionalisation of unactivated carbon-hydrogen (C-H) bonds, in particular, represents a key step in the biosynthesis of many natural products as it provides substrates with increased reactivity for tailoring reactions. In this study, we investigated the function of the P450 enzyme TraB in the terrestric acid biosynthetic pathway. We firstly deleted the gene coding for the DNA repair subunit protein Ku70 by using split marker-based deletion plasmids for convenient recycling of the selection marker to improve gene targeting in Penicillium crustosum. Hereby, we reduced ectopic DNA integration and facilitated genetic manipulation in P. crustosum. Afterward, gene deletion in the Δku70 mutant of the native producer P. crustosum and heterologous expression in Aspergillus nidulans with precursor feeding proved the involvement of TraB in the formation of crustosic acid by catalysing the essential hydroxylation reaction of viridicatic acid. KEY POINTS: •Deletion of Ku70 by using split marker approach for selection marker recycling. •Functional identification of the cytochrome P450 enzyme TraB. •Fulfilling the reaction steps in the terrestric acid biosynthesis.

    Abstract Aim: To assess the association of mental health burden with diabetes-related self-care behaviors and healthcare utilization among older adults.
    Method: This cross-sectional 2019 Behavioral Risk Factor Surveillance System (BRFSS) study included ≥ 65 years old adults with self-reported diabetes. Three groups were used based on the number of days in the past month affected by mental health: 0 days (no burden), 1-13 days (occasional burden), and 14-30 days (frequent burden). Primary outcome was performing ≥ 3 of 5 diabetes-related self-care behaviors. Secondary outcome was performing ≥ 3 of 5 healthcare utilization behaviors. Multivariable logistic regression was used in Stata/SE 15.1.
    Results: Of 14,217 included individuals, 10.2 % reported frequent mental health burden. Compared to 'no burden', 'occasional' and 'frequent burden' groups included more female, obese, not married persons with younger age of diabetes diagnosis, and reported more comorbidities, insulin use, cost-related barriers to see doctors, and diabetes-related eye issues (p < 0.05). 'Occasional/frequent burden' groups reported less self-care and healthcare utilization behaviors, except 30 % higher healthcare utilization was observed in the 'occasional burden' group compared to no burden (aOR 1.30, 95 %CI 1.08-1.58, p = 0.006).
    Conclusions: Overall, mental health burden was associated with reduced participation in diabetes-related self-care and healthcare utilization behaviors in a stepwise manner, except occasional burden was associated with higher healthcare utilization.

    Abstract Background: Hemophagocytic lymphohistiocytosis is a rare hematological syndrome characterized by excessive and uncontrolled activation of the immune system. The often nonspecific nature of early symptoms and the potential for progression to multiorgan failure and death if appropriate therapy is not started promptly, highlight the importance of heightened recognition for this uncommon disease. Although there are well-described associations of hemophagocytic lymphohistiocytosis with infectious, malignant, and autoimmune diseases and an established treatment protocol for these cases, the link between medications and hemophagocytic lymphohistiocytosis is less clearly established and the optimal treatment of these cases less well defined.
    Case presentation: Here we describe the case of a 45-year-old caucasian woman presenting with signs and symptoms consistent with hemophagocytic lymphohistiocytosis, induced by recent exposure to lamotrigine. She had a rapidly progressive clinical course, complicated by multiorgan failure including stress-induced Takotsubo cardiomyopathy and cardiac arrest. With dexamethasone and etoposide therapy, she made a full and sustained recovery.
    Conclusions: This case highlights that medication-induced hemophagocytic lymphohistiocytosis appears to respond similarly to the same dexamethasone and etoposide treatment regimen developed for other non-drug-induced forms of hemophagocytic lymphohistiocytosis. With the continued cessation of the offending agent there has not been need for maintenance therapy and no relapse to date. In addition, given the risk for cardiomyopathy, a clinical complication not classically associated with hemophagocytic lymphohistiocytosis, echocardiogram and telemetry monitoring should be considered in the initial workup of suspected hemophagocytic lymphohistiocytosis.

    Abstract Titanium dioxide (TiO₂) is commonly used for photocatalytic decomposition of organic contaminants for the purpose of water purification. One promising method to enhance TiO₂ photocatalysis is the incorporation of surface plasmon resonance on its surface where photocatalytic reactions take place. Herein, a novel methodology using plasmonically tuned aluminum nanostructures to enhance the rate of photodecomposition of aqueous methyl orange is demonstrated. These nanostructures are tuned to the TiO₂ band gap in the UV regime and patterned on TiO₂-coated substrates using nanosphere lithography. Compared to a blank TiO₂ film, the plasmonics is found to enhance the initial TiO₂ photocatalytic rate by up to 10 times, and further enhancement is possible upon refinement of the plasmonic technology.

    Abstract For individuals with severe to profound hearing loss resulting from irreversibly damaged hair cells, cochlear implants can be used to restore hearing by delivering electrical stimulation directly to the spiral ganglion neurons. However, current spread lowers the spatial resolution of neural activation. Since light can be easily confined, optogenetics is a technique that has the potential to improve the precision of neural activation, whereby visible light is used to stimulate neurons that are modified with light-sensitive opsins. This study compares the spread of neural activity across the inferior colliculus of the auditory midbrain during electrical and optical stimulation in the cochlea of acutely deafened mice with opsin-modified spiral ganglion neurons (H134R variant of the channelrhodopsin-2). Monopolar electrical stimulation was delivered via each of four 0.2 mm wide platinum electrode rings at 0.6 mm centre-to-centre spacing, whereas 453 nm wavelength light was delivered via each of five 0.22 × 0.27 mm micro-light emitting diodes (LEDs) at 0.52 mm centre-to-centre spacing. Channel interactions were also quantified by threshold changes during simultaneous stimulation by pairs of electrodes or micro-LEDs at different distances between the electrodes (0.6, 1.2 and 1.8 mm) or micro-LEDs (0.52, 1.04, 1.56 and 2.08 mm). The spread of activation resulting from single channel optical stimulation was approximately half that of monopolar electrical stimulation as measured at two levels of discrimination above threshold (p<0.001), whereas there was no significant difference between optical stimulation in opsin-modified deafened mice and pure tone acoustic stimulation in normal-hearing mice. During simultaneous micro-LED stimulation, there were minimal channel interactions for all micro-LED spacings tested. For neighbouring micro-LEDs/electrodes, the relative influence on threshold was 13-fold less for optical stimulation compared electrical stimulation (p<0.05). The outcomes of this study show that the higher spatial precision of optogenetic stimulation results in reduced channel interaction compared to electrical stimulation, which could increase the number of independent channels in a cochlear implant. Increased spatial resolution and the ability to activate more than one channel simultaneously could lead to better speech perception in cochlear implant recipients.
