Background: Recent improvement in treatments of cancer has significantly increased survival rates of cancer patients. Unfortunately these treatments such as chemotherapy and radiotherapy can sever damage to the ovaries. Ovarian cryopreservation prior to chemo/ radiotherapy and auto-transplantation post-treatment can restore fertility to cancer patients. Hypoxia in the transplant from delayed re...

the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...

Achieving hemostasis following vascular injury requires the rapid accumulation of platelets and fibrin. Here we used a combination of confocal intravital imaging, genetically engineered mice, and antiplatelet agents to determine how variations in the extent of platelet activation following vascular injury arise from the integration of different elements of the platelet-signaling network. Two fo...

Alveolar osteitis is the most common post operative sequel to tooth extraction. It occurs despite the most exacting operative technique, aseptic procedure and regardless of the ability of surgeons. Various packing materials are available for topical treatment of alveolar osteitis. Purpose: The present study was conducted to evaluate and compare the effectiveness of Zinc Oxide Eugenol dressing, ...

We report an atomic force microscopy (AFM) study of fibrinogen molecules and fibrin fibers with resolution previously achieved only in few electron microscopy images. Not only are all objects triads, but the peripheral D regions are resolved into the two subdomains, apparently corresponding to the βC and γC domains. The conformational analysis of a large population of fibrinogen molecules on mi...

Previous studies have shown that hemostatic thrombi formed in response to penetrating injuries have a core of densely packed, fibrin-associated platelets overlaid by a shell of less-activated, loosely packed platelets. Here we asked, first, how the diverse elements of this structure combine to stem the loss of plasma-borne molecules and, second, whether antiplatelet agents and anticoagulants th...

In a graph G = (V,E), a subset $S⊂V$ is said to be an open packing set if no two vertices of S have a common neighbour in G. The maximum cardinality of an open packing set is called the open packing number and is denoted by $ρ^{o}$. This paper further studies on this parameter by obtaining some new bounds.

Hemostasis after traumatic liver injury can be extremely difficult to obtain, particularly in coagulopathic patients who have suffered extensive liver damage. We determined the ability of a fibrin glue preparation (FG) to terminate ongoing bleeding using a new, clinically relevant porcine model of complex hepatic injury. Anesthetized swine (n = 6, 18 to 19 kg) received an external blast to the ...
