materials and methods in the present study, a potent nk-producing strain was isolated from cow milk and identified. to enhance the yield of nk, effect of various parameters such as ph, temperature, carbon source, nitrogen source and inoculum size were optimized. strain improvement of p. aeruginosa cmss was done by random uv-mutagenesis. nattokinase was partially purified and the activity was de...

In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to st...

Thrombotic disorders, such as myocardial infarction, ischemic stroke, peripheral arterial disease, deep venous thrombosis, pulmonary embolism, or other embolic diseases that are responsible for worldwide mortality and morbidity, are manifestations of the formed thrombi by blood clots during a pathologic blood coagulation process. Once thrombi are formed, the only way to resolve the blood clot i...

abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...

The capacity of saliva to clot blood has been documented in the scriptures (Luke 16:21), folklore, and in the medical literature of the 1920s when Hunter described the ability of saliva to clot blood and proposed it as a means to attenuate bleeding from gastric ulcers.1 In 1938, Glazko and Greenberg reported that saliva contains a cell-derived, protein-based thromboplastin,2 which was later ide...

A 61-year-old man with autosomal dominant polycystic kidney disease suffered from alternating anuria and polyuria resulting from cyst bleeding with clot formation in renal pelvis, a finding which could not be detected by ultrasonography. Subsequent magnetic resonance imaging revealed the right renal pelvis and major calyces were filled with staghorn-shaped blood clots in both coronal sections o...

In early diagnosis of typhoid fever, the emphasis has for long been on the isolation of S. typhi from blood culture. Clot culture techniques have not enjoyed the same vogue, although they are largely used in areas where the disease is endemic. Felix (1924) found that clot culture was hardly ever unsuccessful if blood culture was successful, but that the reverse was frequently true. He attribute...

Respiratory tract obstruction due to a blood clot may result in life threatening ventilatory impairment. Ball valve blood clot obstructions of the airways are rare. A ball valve blood clot acts as a one-way valve, allowing (near) normal air entry into the airways, but (completely) blocking expiration. In a near fatal case of obstruction of the airways by a ball valve blood clot, we performed 'w...
