The aim of the present study was to construct tissue-engineered bone using a bioreactor and platelet-rich plasma (PRP). Bone marrow mesenchymal stem cells (BMSCs) and β-tricalcium phosphate (β-TCP) were cultured in a perfusion bioreactor with PRP-containing medium for 21 days to form a BMSC-TCP composite. Rabbits were then implanted with the BMSC-TCP composite. The morphology of the implanted B...
Autologous platelet-rich plasma (PRP) exerts positive therapeutic effects on hair thickness and density in patients with pattern hair loss. The aim of our study was to evaluate the efficacy of intra-perifollicular autologous PRP and polydeoxyribonucleotide (PDRN) injections in treating female pattern hair loss (FPHL). Twenty FPHL patients were treated with a single session of PRP injection, fol...
هموفیلوس آنفلوانزا تیپ b، نوعی باکتری گرم منفی کپسولدار است و یکی از شایع ترین عوامل مولد مننژیت حاد بشمار می آید. کپسول پلی ساکاریدی این باکتری ؛پلی ریبوزیل ریبیتول فسفات (prp )و پروتئین غشاء خارجی p6 به عنوان ایمونوژن در تولید واکسن علیه هموفیلوس آنفلوانزا نقش دارند .هدف از انجام این مطالعه ، کونژوگه نمودن پروتئین نوترکیب p6(rp6 ) با prp و ارزیابی ایمونولوژیک آن به عنوان کاندیدای جدید واکسینا...
Tricalcium phosphate (TCP) and platelet-rich plasma (PRP) are commonly used in bone tissue engineering. The aim of the present study was to investigate a composite that combined TCP with PRP and assess its effectiveness in the treatment of bone defects. Cavity-shaped bone defects were established on the tibiae of 27 beagle dogs, and were repaired by pure β-TCP with bone marrow stromal cells (BM...
we have previously shown the adjuvant activity of propranolol (prp) (a beta-adrenergic receptor antagonist) using a vaccine model for salmonella typhimurium. in this study prp was used as an adjuvant in combination with plasmodium berghei (p. berghei) whole blood stage (pwbs) antigens. balb/c mice were immunized three times with a 2-week interval, either pwbs vaccine alone or in combination ...
Editorial Platelet rich plasma (PRP), also termed autologous platelet gel, plasma rich in growth factors (PRGF), platelet concentrate (PC), is essentially an increased concentration of autologous platelets suspended in a small amount of plasma after centrifugation. Basically, patient's blood is collected and centrifuged at varying speeds until it separates into 3 layers: platelet poor plasma (P...
Platelet-rich plasma (PRP) is autologous and multifunctional. Platelet concentrate from blood contains highly concentrated platelets and various types of cells, including growth factors. PRP promotes the recovery of cell proliferation and differentiation. Osteonecrosis of the femoral head is a disease caused by femoral head damage or an insufficient blood supply, which leads to the death of bon...
یکی از مسائل مهم طب امروز، بیماری های درگیرکننده ی تاندون ها می باشد. بنابراین هدف از این مطالعه بررسی تاثیر prpخودی در ترمیم نقص تاندونی تجربی در خوکچه هندی می باشد. تعداد40 سر خوکچه ی هندی بالغ، از هر دو جنس تهیه گردید. بعد از بیهوش شدن حیوانات، در سطح خلفی اندام عقبی راست، برشی به طول 3سانتی متر در پوست ایجاد شد. تاندون خم کننده ی عمقی انگشتان مجزا و نقیصه ی تاندونی به طول 7/0 سانتی متر در آ...
BACKGROUND Platelet-rich plasma (PRP) as a storage vehicle of growth factors has been successfully used in clinical applications, but in most cases the platelets were autologous. However, the large volume of blood withdrawn has detrimental effects on patients with anemia or poor general health. To overcome these limitations, this study was designed to separate the growth factors in homologous p...
A series of N-substituted pyrroles having phosphorylcholine with different methylene chain lengths between pyrrole group and phosphorylcholine group were synthesized and their electropolymerizations were performed in aqueous solution. The methylene chains were trimethylene (n = 3), pentamethylene (n = 5), nonamethylene (n = 9), and undecamethylene (n = 11), for 3-(1-pyrrolyl)propyl-2-(trimethyl...
