The eastern green mamba (Dendroaspis angusticeps) is a highly venomous snake species of the mamba genus Dendroaspis native to the coastal regions of southern East Africa. Described by Scottish surgeon and zoologist Andrew Smith in 1849, it has a slender build with a bright green back and green-yellow ventral scales .
ReLEx Small incision lenticule extraction (SMILE), second generation of ReLEx Femtosecond lenticule extraction (FLEx), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism.
Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes. Environmental or acquired factors can alter these inherited traits. [7]
Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
A mamba may retain the same lair for years. Resembling a cobra, the threat display of a mamba includes rearing, opening the mouth and hissing. The black mamba's mouth is black within, which renders the threat more conspicuous. A rearing mamba has a narrower yet longer hood and tends to lean well forward, instead of standing erect as a cobra does.
Incision lines for blepharoplasty. The thorough pre-operative medical and surgical histories, and the physical examination of the patient's periorbital area (eyebrow-to-cheek-to-nose), determine if the patient can safely undergo a blepharoplasty procedure to feasibly resolve (correct or modify, or both) the functional and aesthetic indications presented by the patient.
The most common complication is an increase in eye pressure. The patient is given a topical treatment. [5] Following the surgery, the artificial iris may become misaligned or partially dislocated. This happens when the sutures become loose or if the patient had previous eye trauma around the implantation site that makes the implant fit loosely.
