Summary
Focal choroidal excavation (FCE) often remains stable over time, but choroidal neovascularization can develop. This study analyzed morphological changes in FCE using various imaging techniques.
Area of Science:
- Ophthalmology
- Medical Imaging
- Retinal Diseases
Background:
- Focal choroidal excavation (FCE) is a recognized condition affecting the choroid.
- Understanding its morphological changes is crucial for patient management.
Purpose of the Study:
- To investigate the morphological changes of focal choroidal excavation (FCE).
Main Methods:
- Retrospective review of 18 FCE patients (25 eyes).
- Analysis of ocular fundus images, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (OCT).
- OCT images were the primary tool for evaluating changes during follow-up.
Main Results:
- FCE lesions varied from pigment irregularity to yellowish-white plaques.
- OCT revealed discontinuity in retinal layers and the retinal pigment epithelium/Bruch's complex.
- Choroidal neovascularization developed in 4 patients during the follow-up period.
Conclusions:
- FCE, in both confirming and non-confirming types, can remain stable long-term.
- Choroidal neovascularization is a potential complication that may arise at the site of FCE.

3.5K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

2.0K
Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

01:30Lytic Cycle of Bacteriophages
77.6K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
