The effects of 12-O-tetradecanoylphorbol-13-acetate (TPA) on myeloid colony formation were investigated by initial and delayed addition of TPA to the cultures. In the human placental conditioned medium-stimulated cultures, TPA inhibited normal myeloid colony formation without any change in colony morphology when added at the beginning of culture. However, macrophage-like transformation of myelo...
Coupling tissue-type plasminogen activator (tPA) to carrier red blood cells (RBC) prolongs its intravascular life span and permits its use for thromboprophylaxis. Here, we studied the susceptibility of RBC/tPA to PA inhibitors including plasminogen activator inhibitor-1 (PAI-1) that constrain its activity and may reduce the duration of its effect. Despite lesser spatial and diffusional limitati...
The process of acute release of tissue-type plasminogen activator (tPA) is important in locally speeding up fibrinolysis. Using a sensitive enzyme-linked immunosorbent assay for tPA, we investigated the acute release of tPA from cultured human umbilical vein endothelial cells. The addition of thrombin (0.003 to 3 NIH U/mL) caused the dose-dependent release of noncomplexed, enzymatically active ...
Current treatment with tissue plasminogen activator (tPA) requires an intravenous infusion (1.5-3 h) because the clearance of tPA from the circulation is rapid (t 1/2 approximately 6 min). We have developed a tPA variant, T103N,N117Q, KHRR(296-299)AAAA (TNK-tPA) that has substantially slower in vivo clearance (1.9 vs. 16.1 ml per min per kg for tPA in rabbits) and near-normal fibrin binding and...
The characteristic texture of turrón, torrone and nougat was examined. They are typical European confections prepared from almonds, honey, sugars and/or chocolate. Three different instrumental tests: puncture, cutting, and Texture Profile Analysis (TPA), were used in this study and samples prepared from three countries (Spain, Italy, and France), and by six manufacturing companies (two companie...
Reperfusion therapy with tissue plasminogen activator (tPA) is a rational therapy for acute ischemic stroke. Properly titrated use of tPA improves clinical outcomes. However, there is also an associated risk of hemorrhagic transformation after tPA therapy. Emerging data now suggest that some of these potentially neurotoxic side effects of tPA may be due to its signaling actions in the neurovasc...

در سال¬های اخیر، استفاده از گیاهان به¬عنوان میزبان¬هایی برای تولید پپتیدهای نوترکیب باارزش، به¬دلیل مزایایی همچون ایمنی بالا، هزینه پایین و تغییرات پس از ترجمه، سطح وسیعی از تحقیقات را به¬خود اختصاص داده است. یکی از پپتیدهای باارزشی که هزینه بالای تولید آن، بررسی سایر سیستم¬های تولید پروتئین نوترکیب نظیر گیاهان را برای تولید ارزان¬ و ایمن¬تر آن، الزامی کرده است، فعال¬کننده پلاسمینوژن بافتی (tpa...
گیاهان به دلیل تولید پروتئین نوترکیب با هزینه پایین، تولید انبوه و ایمنی بالا، به عنوان جایگزین مناسبی برای سیستمهای رایج تولید پروتئین نوترکیبدارویی، بویژه در فرمانتور مطرح میباشند.فعال کننده پلاسمینوژن بافتی(tpa) یکی از پروتئینهای دارویی است که برای حل کردن لختههای خونی در سکتههای قلبی و مغزی کاربرد گسترده ای دارد و به دلیل کمیاب بودن و قیمت بالا در دسترس عموم بیماران نمیباشد. گیاهان تر...
To investigate the fluorination influence on the photovoltaic performance of small molecular based organic solar cells (OSCs), six small molecules based on 2,1,3-benzothiadiazole (BT), and diketopyrrolopyrrole (DPP) as core and fluorinated phenyl (DFP) and triphenyl amine (TPA) as different terminal units (DFP-BT-DFP, DFP-BT-TPA, TPA-BT-TPA, DFP-DPP-DFP, DFP-DPP-TPA, and TPA-DPP-TPA) were synth...
