(1) To determine the serum levels of vascular endothelial growth factor (VEGF) and insulin- like growth factor- 1 (IGF1) in women with polycystic ovary syndrome (PCOS). (2) To study Doppler blood flow changes within the ovarian stroma of women with PCOS. (3) To evaluate the relationship between VEGF and IGF- 1 and Doppler indices as well as hormonal profile. Department of Obstetrics and Gynecology, and Department of Biochemistry, Faculty of Medicine, Assiut University, Egypt. Cross- sectional study. Fifty infertile women with PCOS diagnosed by ultrasound examination and a history of oligomenorrhea, hirsutism and obesity were studied. Serum levels of vascular endothelial growth factor (VEGF), insulin- like growth factor- 1 (IGF- 1) and hormonal profile were measured. Doppler blood flow velocity waveforms analysis in both right and left intraovarian arteries was done. Twenty healthy and fertile women with regular menstrual cycles served as a comparison group were similarly studied at the third day of the cycle. The serum levels of VEGF,IGF- 1 (4.79 ± 0.91, 253.15 ± 70.07 versus 2.39 ± 0.42, 186.65 ± 42.7) were significantly elevated (P < 0.001 and P < 0.01, respectively) in women with PCOS compared with control. Doppler indices, PI (2.01 ± 0.77, 2.66 ± 1.00 versus 2.98 ± 0.77, 3.75 ± 0.98) and RI (0.77 ± 0.12, 0.82 ± 0.09 versus 0.87 ± 0.09, 0.89 ± 0.09) in both right and left intraovarian vessels were significantly lower in the patients than controls. The VEGF and IGF- 1 levels were negatively correlated with RI and PI in the uterine and intraovarian arteries. VEGF level was positively correlated with IGF- 1 (r = 0.41, P <.0.05) in women with PCOS. Higher serum levels of VEGF and IGF- 1 in PCOS women may be related to the increased vascularity that underlies the increased blood flow demonstrated by Doppler blood flow measurements in these women.

当前的小型天线依赖于电磁波的谐振,因此天线的尺寸与电磁波波长相关。典型的天线尺寸大于波长的1/10,而进一步缩小天线尺寸在近十年来都是一个公开的挑战。介绍一种通过悬浮铁氧/压电薄膜异质结构的声波激励纳机械磁电天线。这种磁电天线通过其在声波谐振频率处的磁电效应接收和发射电磁波。磁电天线中的体声波激发铁磁薄膜的磁化振荡,产生电磁波的辐射;反之,天线感应电磁波的磁场,得到压电电压输出。这种磁电天线(尺寸仅为波长的千分之一)比现有小型天线的尺寸小1到2个数量级,但性能却没有降低,在便携式无线通信系统中具有很大的应用潜力。
