In order to elucidate the correlation between lens optical function and metabolic function, in vitro bovine lens optical quality and mitochondrial integrity was measured following treatment with carbonyl cyanide m-chlorophenylhydrazone (the mitochondrial depolarizing agent, CCCP). The results indicate that in vitro exposure to CCCP resulted in concentration and time-dependent loss of sharp focus. The concentrations tested included 65.0, 32.5, 16.25 and 8.125 microm CCCP. Lenses treated with two lower concentrations show recovery from damage at the 24-h scan point. In lenses treated with 65 microM CCCP, mitochondria in lens epithelial and superficial cortical fibre cells appeared short and swollen. The results of this study indicate that lens optical function and mitochondrial integrity are closely correlated.

Purpose: To develop and assess the psychometric properties of a quality of life (QoL) assessment tool for Chinese patients treated with intravitreal injection (IVI) of anti-vascular endothelial growth factor (anti-VEGF).
Methods: We developed a 31-item IVI-QoL questionnaire using semi- structured patient interviews and expert panel consultation, drawing on a study of the literature. After pretesting on a subset of patients undergoing IVI, the questionnaire was pared down to 23 items.

Purpose: To evaluate the presence and progression of maculopathy in patients with sickle cell disease (SCD) using Optical Coherence Tomography (OCT) and OCT-Angiography (OCTA), and to identify clinical/laboratory risk factors for progression during follow-up.
Methods: Complete ophthalmic examination, including fundoscopy and macular SD-OCT/OCTA scans, was performed in consecutive SCD-patients (HbSS/HbSβ0/HbSβ+/HbSC genotype) during baseline and follow-up visits. SCR stage was based on fundoscopy instead of the Goldberg classification, since fluorescein angiography was not routinely used.

Precise and sensitive analysis of specific DNA in actual human bodily fluids is crucial for the early diagnosis of major diseases and for a deeper understanding of DNA functions. Herein, by grafting a peptide-conjugated hairpin DNA probe to a covalent organic framework (COF)-based photocathode, a robust anti-interference photoelectrochemical (PEC) DNA bioassay was explored, which could specifically resist potential interference from nonspecific proteins and reducing species. Human immunodeficiency virus (HIV) DNA was used as the target DNA (tDNA) for the PEC DNA bioassay.

Electronic devices cover a large subset of daily life gadgets which use power to run, hence increasing the load of the energy needs and indirectly impacting greenhouse gas emissions. Smart electrochromic windows provide a solution to this through remarkable energy saving by adjusting optical behavior depending on the environmental conditions. Since the electrochromic windows also need power to run, a self-powered electrochromic panel will be a better solution.

The physiological and clinical importance of motile cilia in reproduction is well recognized, however, the specific role they play in transport through the oviduct and how ciliopathies lead to subfertility and infertility is still unclear. The contribution of cilia beating, fluid flow, and smooth muscle contraction to overall progressive transport within the oviduct remains under debate. Therefore, we investigated the role of cilia in the oviduct transport of preimplantation eggs and embryos using a combination of genetic and advanced imaging approaches.
