Choroidal neovascularization (CNV) is a common pathologic lesion that occurs in various chorioretinopathy. Although the incidence of CNV is quite rare in children and adolescents, these lesions have a severe impact on visual acuity and quality of life over patients' lifetime. The management of CNV in pediatric patients is challenging, clear guidelines are limited due to a lack of randomized clinical trials. However, the more promising option is the use of vascular endothelial growth factor (VEGF) inhibitors...

Stimuli responsive luminescent materials possessing room temperature phosphorescence (RTP) are extremely desirable for various applications. The here investigated derivative of cyclic triimidazole (TT) functionalized with carbazole (Cz), namely TT-Ph-Cz, belongs to this class. TT-Ph-Cz possesses high conformational freedom resulting in rigidochromic and multi-stimuli responsive emissive behavior. It has been isolated as MeOH-solvated and de-solvated forms characterized by distinctive emissive features. In particular, the solvated form, in which hydrogen bonds with MeOH inhibit competitive non-radiative deactivation channels, possesses a higher quantum yield associated with a strong phosphorescence contribution which is preserved in DMSO/water solutions...

Transcript levels of BSE-treated and untreated plants were studied by RNA-seq and validated by quantitative real-time PCR analysis (RT-qPCR). Root morphology, sugar yield, and processing quality traits were also analyzed to better elucidate the treatment effects. RNA-seq revealed 1019 differentially expressed genes (DEGs) between the BSE-treated and untreated plants. An adjusted p -value < 0...

The development of organic room-temperature phosphorescent (ORTP) materials represents an active field of research due to their significant advantages with respect to their organometallic counterparts. Two cyclic triimidazole ( TT ) derivatives bearing one and three hexyl-thiophene moieties, TT-HThio and TT-(HThio)3 , have been prepared and characterized. Both compounds display enhanced quantum yields in their crystalline form with respect to those in a solution state, revealing crystallization-enhanced emissive (CEE) behavior...

INTRODUCTION: SB11 (Byooviz™) is a ranibizumab biosimilar that acts as a vascular endothelial growth factor (VEGF)-A inhibitor. Stability data for unopened SB11 vials at room temperature are limited and no data are available for SB11 withdrawn into syringes (in-use) for intravitreal administration. METHODS: SB11 stability was assessed in two different settings: unopened vials stored at 30 ± 2 °C/65 ± 5% relative humidity (RH) for 2 months, and in-use SB11 withdrawn into syringes stored at 5 ± 3 °C for 98 days and then 25 ± 2 °C/60 ± 5% RH for 24 h...

IMPORTANCE: SB11 and reference ranibizumab (RBZ) are monoclonal anti-vascular endothelial growth factor (VEGF)-A antibodies approved for the treatment of neovascular age-related macular degeneration (nAMD) and other retinal diseases. The association of ranibizumab immunogenicity and treatment outcomes in patients with nAMD is unclear but relevant regarding concerns about immunogenicity of anti-VEGF biological products. OBJECTIVE: To examine the association of immunogenicity to ranibizumab products (SB11 and RBZ) with efficacy, safety, and pharmacokinetics...

The multicenter, noninterventional prospective BLUE SKY study investigates brolucizumab treatment with different schemes in 600 treatment-naive and pretreated nAMD patients in routine clinical practice over a 24-month period...

BACKGROUND: Pre-hospital emergency medical systems do not appear to work totally coordinated with Accident and Emergency (A&E). Often, patient admission to A&E is marked by scarce attention to the handover between the respective healthcare professionals. This phenomenon is potentially dangerous because it exposes patients to the risk of errors in a context where the patients' critical or progressing conditions must not be worsened by avoidable errors of communication between professionals...
