The first exploratory study was conducted on the compound eye morphology and spectral characteristics of (Selman & Vogt, 1971) to clarify its eye structure and its spectral sensitivity. Scanning electron microscopy, paraffin sectioning, and transmission electron microscopy revealed that has apposition compound eyes with both eucones and open rhabdom. The micro-computed tomography (CT) results after 3D reconstruction demonstrated the precise position of the compound eyes in the insect's head and suggested that the visual range was mainly concentrated in the front and on both sides of the head. The electroretinogram (ERG) experiment showed that red, yellow, green, blue, and ultraviolet light could stimulate the compound eyes of to produce electrical signals. The behavioural experiment results showed that both males and females had the strongest phototaxis to yellow light and positive phototaxis to red, green, and blue light but negative phototaxis to UV light. This study of the compound eyes of will be helpful for decoding its visual mechanism in future studies.

Background: The global increase in diabetes mellitus has been accompanied by a significant rise in related complications. Diabetic patients frequently experience ocular surface disorders and multiple studies have demonstrated that the diabetic corneal epithelium is characterized by increased cellular fragility and compromised barrier integrity. It has been demonstrated that the processes of oxidative stress and inflammation are pivotal in causing ocular tissue damage in diabetic patients.

Bardet-Biedl Syndrome (BBS) is a rare autosomal recessive ciliopathy characterized by genetic heterogeneity. Despite significant progress in understanding the BBSome-coding genes associated with ciliopathies, the pathogenesis linked to mutations in chaperonin-coding genes (BBS6, BBS10, and BBS12) remains poorly defined. This study aims to confirm the genetic diagnosis of BBS and elucidate the pathological mechanisms in causative genes of BBS10 and BBS12.

Xenopus embryo serves as an ideal model for teratogenesis assays to observe the effects of any compounds on the cellular processes crucial for early development and adult tissue homeostasis. In our screening of a chemical library with frog embryo, caffeic acid phenethyl ester (CAPE) was found to upregulate the FGF/MAPK pathway, disrupting germ layer formation in early development. Exposure to CAPE interfered with the formation of anterior-posterior body axis and of ectodermal derivatives such as eyes, dorsal fin and pigment cells.

Background: Multidrug-resistant bacterial infections have high mortality rates and few treatment options. Synergistic combinations may improve clinical outcome but traditional strategies often damage healthy microbiome. Oxazolidinone-class antibiotics are typical last-resort drugs for treating drug-resistant bacterial infections but are becoming less effective due to resistance development.

Optical superposition natural compound eyes (OSNCEs) allow circadian insects to thrive in varying light conditions thanks to their unique anatomical structures. This provides a blueprint for optical superposition artificial compound eyes (OSACEs) that can adapt to different illumination intensities. However, OSACEs have received limited research attention until recently, with most studies focusing on apposition compound eyes that operate only in bright light.
