The patient reported visual field outages, and after subsequent computed tomography, she was interdisciplinary managed and surgery was done on at the Neurosurgical Department. After the operation, there was a significant improvement without a pathological finding on the perimeter.
Neurotrophic keratopathy (NK) is adegenerative corneal disease caused by damage to the trigeminal innervation due to adecrease in corneal sensitivity or complete anaesthesia. Impaired corneal innervation leads to morphological and metabolic disorders of the epithelium. In addition, it also leads to the development of recurrent or persistent epithelial defects in corneal ulcers, which may progress to stromal lysis and corneal perforation. One possible solution for severe NK is reinnervation of the anaesthetic cornea (corneal neurotization) using the supraorbital nerve and an autologous sensory nerve graft (indirect neurotization). This article presents the results of corneal neurotization in ayoung male patient with persistent epithelial defects and corneal ulcers due to corneal denervation.

A22-year-old man with ahistory of neurosurgery for astrocytoma of the cerebellum and trunk on the right side at the age of 2 years, was observed for postoperative paresis of the right facial nerve with lagophthalmos in using the supraorbital nerve and the autologous sensory nerve graft represents a new solution for severe NK treatment. The severe corneal condition in our patient healed after the surgery.
To retrospectively evaluate the use of cyclocryocoagulation (CCK) in secondary neovascular glaucomas performed at the Department of Ophthalmology, Faculty of Medicine, Charles University and University Hospital Hradec Králové in the years 2016-2019.

In aretrospective study, 30 procedures of 26 eyes of 24 patients were evaluated. All patients underwent CCK surgery. The main entry criteria were the presence of secondary neovascular glaucoma in diabetes or on the basis of occlusion of the retinal artery or vein and subsequent dispensarization of the patient in the 1st and 6th month after the operation. The parameters evaluated were the best-corrected visual acuity (BCVA), intraocular pressure value (IOP), data of pain and change in the number of active substances of antiglaucoma therapy.

The mean age of patients at the time of the procedure was 62 years (range 22-85 years). The average number of procedures per eye was 1.15 out of atotal of 30 procedures, 26 eyes were performed on 24 patients. The most commnderwent two procedures on the same eye during the study period. One of them had two procedures on both eyes. The average value of the number of active substances of antiglaucoma drugs decreased from 3.10 to 2.87 after the 1st month (p = 0.318) and after 6 months it was 2.6 (p.
The main aim of this work was to find out if there is acorrelation between vessel density (VD) and results of measured perfusion values in ophthalmic artery and in central retinal artery of the same eye in agroup with hypertension glaucoma (HTG).

The file included 20 patients with HTG, thereof 13 women of average age 68.7 years (49-80 years) and 7 men of average age 58.4 years (27-81 years). Criteria for inclusion in the study visual acuity 1,0 with possible correction less than ±3 diopters, approximately the same changes in visual fields in every patient, intraocular pressure (IOP) less than 18 mmHg, no other ocular or neurological diseases. VD was measured by Avanti RTVue XR by Optovue firm, perfusion parameters were measured using Doppler ultrasound with Affinity 70G machine by Philips firm. The peak systolic velocity (PSV) and end diastolic velocity (EDV) and resistance index (RI) were measured both in ophthalmic artery (AO) and in central retinal artery (CRA). Visual field (VF) was examined by quick suitable than Doppler ultrasound for determining the condition of blood circulation in the eye.
Measured values showed that the vascular component of VD has a huge impact on the changes in visual fields in HTG. Weak to moderate influence exists between VD and RI in CRA. OCTA has proven to be more suitable than Doppler ultrasound for determining the condition of blood circulation in the eye.
Analysis of the presence of choroidal neovascularization (CNV) by optical coherence tomography angiography (OCTA) in eyes treated with photodynamic therapy in areduced dosing regimen (HD-PDT, half dose of verteporfin) for the chronic form of central serous chorioretinopathy (cCSC).

Retrospective evaluation of OCTA findings in 54 eyes of 52 patients treated for cCSC with HD-PDT. OCTA was performed on Angioplex Zeiss Cirrus 5000 (Carl Zeiss Meditec, Dublin, CA, USA) 1 year after HD-PDT to verify changes typical of cCSC. By analyzing the results of this examination, we evaluated in particular the presence or absence of concomitant CNV and the correlation of the present CNV with the average resulting best corrected visual acuity (BCVA).

We analyzed the OCTA findings of 54 eyes (52 patients), in which we demonstrated the presence of concomitant CNV in 35 eyes (35.2%). Revealed CNV occurred in 82% below the undulating hyperreflective RPE line. In eyes with CNV, the mean BCVA (72 letters ETDRS) was statistically significantly lower than in eyes without CNV (82.7 letters ETDRS) (p=0.0179).

In our retrospective evaluation of agroup of patients who underwent HD-PDT for cCSC, we demonstrated with OCTA the presence of CNV in 35.2% eyes 1 year after the treatment. We believe that the presence of type ICNV is acomplication of the chronic disease itself rather than an adverse effect of HD-PDT.

The reaction is performed by oxidation with carbazole (CbzH) in tetrahydrofuran (THF) at 50 °C with subsequent crystallization in toluene (C7H8). The oxo cluster contains noncharged molecular units with a central Sm6O4 core. Single-crystal structure analysis and infrared spectroscopy confirm the oxidation of CbzH with the formation of (cbz)-. Polynuclear carbazole complexes are generally rare and here prepared using metal nanoparticles as a reactive starting material for the first time. The reaction with CbzH as a sterically demanding ligand exemplarily shows the feasibility of rare-earth-metal nanoparticles for obtaining new compounds with complex composition and structure.Designing and fabricating high-performance microwave absorption materials with efficient electromagnetic absorption and corrosion resistance becomes a serious and urgent concern. Herein, novel corrosion-resistant graphene-based carbon-coated iron (Fe@C) magnetic composite foam is fabricated via self-assembly of iron phthalocyanine/Fe3O4 (FePc hybrid) on the graphene skeletons under solvothermal conditions and then annealing at high temperature. As a result, the rational construction of a hierarchical impedance gradient between graphene skeletons and Fe@C particles can facilitate the optimization in impedance matching and attenuation characteristic of the foam, realizing the efficient dissipation for incident electromagnetic waves. Additionally, the performance of electromagnetic absorption can be controllably regulated by optimizing annealing temperature and/or time. More importantly, the formation of a carbon-coated iron structure substantially improves the corrosion resistance of magnetic particles, endowing the composite foam with excellent stability and durability in microwave absorption performance.Using real-time measurements of CO2 and volatile organic compounds (VOCs) in the air handler of an occupied middle school, we quantified source strengths for 249 VOCs and apportioned the source to the building, occupants and their activities, outdoor air, or recirculation air. For VOCs quantified in this study, there is a source to the outdoors of 8.6 ± 1.8 g/h in building exhaust air, of which 5.9 ± 1.7 g/h can be attributed to indoor sources (the building and occupants and their activities). The corresponding whole-building area emission factor from indoor sources is 1020 ± 300 μg/(m2 h), including reactive VOCs like isoprene and monoterpenes (33 ± 5.1 and 29 ± 5.7 μg/(m2 h), respectively). Per-person emission factors are calculated for compounds associated with occupants and their activities, e.g., monoterpenes are emitted at a rate of 280 ± 80 μg/(person h). The air handler included carbon scrubbing, reducing supply air concentrations of 125 compounds by 38 ± 19% (mean ± std. dev.) with a net removal of 2.4 ± 0.4 g/h of organic compounds from the building. This carbon scrubber reduces steady-state indoor concentrations of organics by 65 μg/m3 and the contribution of indoor sources of VOCs to the outdoor environment by ∼40%. These data inform the design and operation of buildings to reduce human exposure to VOCs inside buildings. These data indicate the potential for gas-phase air cleaning to improve both indoor air quality and reduce VOC emissions from buildings to the outdoor environment.The reductive Heck cyclization of nonracemic benzylidene γ-butyrolactone is studied toward the asymmetric synthesis of aryltetralin lignans, where the stereochemistry of the benzylidene lactone is found to control the mode of cyclization. The Z-isomer undergoes mostly 6-endo-cyclization and provides the desired (-)-isopodophyllotoxin along with a minor amount of 5-exo-cyclized product, but the E-isomer goes through exclusively 5-exo-cyclization, leading to the undesired dihydroindenolactone compound instead of (-)-podophyllotoxin. The experimental results are well-supported by the DFT studies.Ag-catalyzed nitrene transfer (NT) converts C-H bonds into valuable C-N bonds. These reactions offer a promising strategy for catalyst-controlled regiodivergent functionalization of different types of reactive C-H bonds, as the regioselectivity is tunable by varying the steric and electronic environments around the Ag nitrene, as well as the identity of the nitrene precursors and the tether length. Therefore, a unified understanding of how these individual factors affect the regioselectivity is key to the rational design of highly selective and regiodivergent C-H amination reactions. Herein, we report a computational study of various Ag-catalyzed NT reactions that indicates a concerted H-atom transfer (HAT)/C-N bond formation mechanism. A detailed analysis was carried out on the effects of the C-H bond dissociation enthalpy (BDE), charge transfer, ligand-substrate steric repulsions, and transition state ring strain on the stability of the C-H insertion transition states with different Ag nitrene complexes. https://www.selleckchem.com/products/Vorinostat-saha.html The ancillary ligands on the Ag and the nitrene precursor identity both affect transition state geometries to furnish differing sensitivities to the BDE, tether length, and electronic effects of the reactive C-H bonds. Based on our understanding of the dominant factors that control selectivity, we established a rational catalyst and precursor selection approach for regiodivergent amination of diverse C-H bonds. The computationally predicted regiodivergent amination of β- and γ-C-H bonds of aliphatic alcohol derivatives was validated by experimental studies.
