background: we performed this study to evaluate use of fresh and frozen sperm samples in non-obstructive azoospermia microdissection testicular sperm extraction (micro-tese-icsi) treatment. methods: we performed a total of 82 consecutive in vitro fertilization (ivf) cycles at fertijin ivf center in istanbul, turkey from january 2010 to march 2012. in 43 participants we used fresh sperm and froz...

bovine leukemia provirus: evidence of presence of part of gag gene inseminal plasma of naturally infected bullsit is of critical importance to understand the modalities of blv presence in semen, especially with regard to artificial insemination (ai). presence of bovine leukemia provirus was demonstrated in fresh and frozen semen samples by researchers. in this study paired blood and semen sampl...

Some molecular analyses require microgram quantities of DNA, yet many epidemiologic studies preserve only the buffy coat. In Frederick, Maryland, in 2010, we estimated DNA yields from 5 mL of whole blood and from equivalent amounts of all-cell-pellet (ACP) fraction, buffy coat, and residual blood cells from fresh blood (n = 10 volunteers) and from both fresh and frozen blood (n = 10). We extrac...

Trauma-induced coagulopathy represents a life-threatening complication in severely injured patients. To avoid exsanguination, rapid surgical bleeding control coupled with immediate and aggressive haemostatic treatment is mandatory. In most trauma centres, coagulation therapy is established with transfusion of high volumes of fresh frozen plasma. Due to logistic issues, only busy trauma faciliti...

In acute clinical settings where there may be a role for antioxidant therapy, patients receive large amounts of i.v. fluids which may have antioxidant activity. To investigate such effects the antioxidant capacity of nine i.v. fluids was measured (Gelofusine, Haemaccel, 20% mannitol, 4.5% human albumin solution, fresh frozen plasma, aprotinin, N-acetylcysteine and two hydroxyethyl starch soluti...

Production of high quality embryos in vitro needs an efficient in vitro fertilization (IVF). Seminal origin is one of the important factors that affects the success of in vitro embryo production. So our goal was to determine the effect of using fresh and frozen semen in fertilization on developmental competence and cryo-survival of buffalo embryos. Buffalo oocytes wer...

Numerous published guidelines encourage appropriate use of fresh frozen plasma (FFP). However, adherence is documented as poor. Therefore, we sought to determine the laboratory effect of FFP administration to patients with an international normalized ratio (INR) less than 1.6 (prothrombin time <1.6 times normal). We found minimally prolonged INRs decreased with treatment of the underlying disea...

 ABSTRACT Background: Aprotinin has been used increasingly to reduce postoperative blood loss in open-heart operations due to the potentialities for complications and high cost, it would seem reasonable to use aprotinin more selectively in small doses in the prime solution of the pump. Methods: We prospectively studied the effect of preoperative low dose aprotinin [2 million units (230mg)] on b...

We assessed a modified multichannel thromboelastogram for differentiation of the causes of coagulopathy after cardiopulmonary bypass and its suitability as a therapy guide. Thirty adult patients undergoing surgery with cardiopulmonary bypass, who revealed a coagulopathy as observed by a prolonged activated clotting time of >150 sec after the application of protamine, were enrolled. Therapy was ...
