Simplified Convolutional Neural Network Application for Cervix Type Classification via Colposcopic Images.

The inner parts of the human body are usually inspected endoscopically using special equipment. For instance, each part of the female reproductive system can be examined endoscopically (laparoscopy, hysteroscopy, and colposcopy). The primary purpose of colposcopy is the early detection of malignant lesions of the cervix.

PRK using an absorbing cell delivery system for correction of myopia from 4 to 26 D in 3251 eyes.

An ophthalmic laser unit with a Lambda-Physik LPX excimer emitting 193 nm and a unique beam shaping system was designed at the Complex "Eye Microsurgery." An absorbing cell, used as the main element of the delivery system, allowed us to obtain a precise profile of the laser energy density on the patient's cornea, smoothly changing the corneal refraction with each shot in the whole ablation area. The absorbing cell also allowed for varying the shape of distribution of radiation energy density depending on the patient's corneal shape.

Comparative study of two protein-coding regions of mitochondrial DNA from three endemic sculpins (Cottoidei) of Lake Baikal.

Two protein-coding regions (cytochrome b, ATPase 8, and part of ATPase 6) from mitochondrial DNA of Cottus kessleri, Cottocomephorus grewingki, and Cottocomephorus inermis--Baikalian endemic sculpins--were amplified via polymerase chain reaction, and sequenced. Two novel primers--L8352 (5'-TAAAGATTGGTGAC TCCCAACCACC) and H8773 (5'-GTAGGGAGT AAGCCCAATATGTT)--were used for the latter region. Phylogenies suggested by sequence divergence of the genes of ATPases appeared to be different from those computed from data for cytochrome b.

Radial thermokeratoplasty for the correction of hyperopia.

Hyperopic thermokeratoplasty involves making controlled thermal burns in the corneal stroma in a radial pattern up to a premarked clear zone. It steepens the central cornea and reduces the hyperopia. A series of 117 radial thermokeratoplasty eyes done in the Soviet Union were analyzed.

Influence of some factors on the sutures of the lens.

A clinical study of the lens transparency conditions was made on 118 patients with regard for an applicable treatment, the use of hyperbaric oxygenation and a type of lesion. It showed, that sutures of the lens were wider in patients with uveitis and in diabetic patients as compared with the control-group patients who had no other pathologies. Glaucomatous patients had very narrow sutures.

Corneal biomicroscopy following repeated radial keratotomy.

Two distinct forms of corneal incision healing are described following repeated radial keratotomy. The new incisions were made along the old corneal scars. No complications were observed intra- or postoperatively.

1004 cases of traumatic cataract surgery with implantation of an intraocular lens.

Traumatic cataracts occurring after ocular trauma were removed by phacoemulsification, cryoextraction or extracapsular cataract extraction, depending on the degree of lens absorption. All eyes received sputnik-style iridocapsular lenses. Most cases were complicated by the presence of synechiae and/or the need for iridoplasty.

The state of eye hydrocircular system in view of age pathology and open-angle glaucoma.

With age the eye drainage system undergoes a number of changes because less favorable conditions arise for intraocular fluid reflux. The manifestation and extent of these changes were closely connected with the manifestation of arteriosclerotic affection of the cardiovascular system. The changes in eye drainage passages in persons with pronounced complicated arteriosclerosis and advanced open-angle glaucoma were identical in character and comparable in the manifestation.

Calculation of the optical power of intraocular lenses.

A rather simple clinical approach has been used to derive formulas necessary to calculate the power of pupillary intracameral prosthetics and these have been applied in 150 eyes. In 136 eyes, the postoperative measurements were within one diopter of preoperative calculations.
