By using the theory of exponential dichotomy and Banach fixed point theorem, this paper is concerned with the problem of the existence and uniqueness of almost periodic solution in a harvesting Lotka-Volterra recurrent neural networks on time scales. To a certain extent, our work in this paper corrects the defect in [Y.G. Liu, B.B. Liu, S.H. Ling, The almost periodic solution of Lotka-Volterra ...

Posterior dislocation of the shoulder is an uncommon injury. Diagnosis is difficult and often missed. Once diagnosed, management must be individualized depending on the amount of the defect of the humeral head and the time from injury. This article presents a case of a 40-year-old man with a 4-month history of bilateral locked posterior fracture-dislocation of the shoulders after a grand mal se...

there are few reports about congenital indifference to pain or hereditary and sensory autonomic neuropathy (hsan). several investigations for pathophysiology of this syndrome have been performed and different classifications about it. in this report we present a case of hsan type ii with general absence of pain and self amputations and leprosy–like damage of extremities which was suspected to b...

rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. the disfigurement associated with the loss of an eye may result in significant physical and emotional problems. various treatment modalities are available, one of which is the use of implants. although implant-supported orbital prosthesis has a superior outcome, it may not b...

background:   to introduce our experience of using the free neurovascular flap from great and second toe. methods:   thirteen patients (fifteen fingers) sought surgical treatment for soft tissue defects of the hand at our medical institutin between march 2006 and september 2009. in two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. i...

in this investigation the effects of excess vitamin a administration during the early embryonic period were studied. intramuscular injection of a single dose of 15000,20000 or 25000 iu/kg vitamin a to pregnant balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (cns) including exencephaly, hydroc...

Three-dimensional measurement and defect detection is an effective guarantee for improving the product quality. In this paper, we present a new 3-D overall measurement method using only one image, which can be effectively used in the defect detection. Compared with the former defect technology, such as the eddy current technology, the leakage of magnetic technology, the infrared technology, and...

in the present research, molecular detection of bovine leukocyte adhesion deficiency (blad) and complex vertebral malformation (cvm)in a population of iranian holstein cows has been carried outusing milk somatic cells by polymerase chain reaction-restriction fragment length polymorphism(pcr-rflp). the blad and cvm are monogenic and autosomal recessive heredity lethal syndrome in holstein-friesi...

background : due to the increased prevalence of celiac disease in chromosomal anomalies and other congenital anomalies, this study was conducted to evaluate the seroprevalence of celiac disease (cd) in patients with congenital heart defects (chd). methods: this case-control study was done on 1002 children in two groups of chd patients (n=402) and controls (n=600). the serum tissue transglutamia...
