Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...

In our previous studies, we noted a non-uniform distribution of protein tracer preferentially entering the anterior stromal lamellae of the cornea from the limbus. Given other differences reported previously between the anterior and posterior lamellae of the cornea, and the number of corneal disorders in which abnormalities are preferentially confined to either the anterior or posterior lamella...

PERFORATING keratoplasty is found to be most successful in cases of small central corneal nebulae and keratoconus. In both these conditions the graft lies completely surrounded by healthy cornea. Where there is gross opacification extending widely throughout the thickness of the cornea and especially if degenerative changes are present, then a simple perforating graft rapidly becomes completely...

ExtractDefective corneas are the leading cause of blindness world wide and the second leading cause, after diabetic retinopathy,of blindness in the united state , afflicting 30000 americans each year. happily, nearly 95 percent of those who have corneal transplantations( in 1985 they numbered,26300) regain their sight. The cornea is a transparent, a vascular, dim-sized tissue continious with th...

Biologics, like peptides, proteins and nucleic acids, have proven to be promising drugs for the treatment of numerous diseases. However, besides off label use monoclonal antibody bevacizumab corneal neovascularization, date no other biologics diseases reached market. Indeed, delivering in eye remains a challenge, especially at level cornea. While it appears rather accessible tissue administrati...

The use of Frozen-section during surgical procedures, gives the surgeon valuable information and guides him to perform the appropriate surgical procedure. In order to determine the accuracy of Frozen-section in gynecologic surgery, we compared the results of 172 gynecologic Frozen-section diagnosis with their final diagnosis in Mirza Kockak Khan Hospital, from 1378 to 1379. A total of 106 ovari...

Background: Currently, frozen embryo transfers contribute an increasing rate of births from assisted reproductive technologies such as in vitro fertilization (IVF). However, very few studies evaluated the neonatal outcomes from frozen embryo transfer. This study aimed to investigate and compare the neonatal outcomes from frozen embryo transfer versus fresh embryo transfers. Materials and Method...
