Background: To determine the ultrasonic measurement of female pelvic reproductive organs and compare the BMI between fertile and infertile women Methods: In this descriptive study 120 women, 60 fertile and 60 infertile, subdivided into age groups 20 to 30, and 31 to 40, were included. Total ovarian volume (OV) was determined transabdominally (OV-TA) and transvaginally (OV-TV), antral follicle c...

Cyanide-resistant (alternative) respiration by tissues of 7 male-sterile lines from 4 species (Glycine max (L.), Helenium amarum (Raf.) H. Rock., Plantago lanceolata L. and Zea mays L.) was compared with that of fertile tissues. Six of the 7 male-sterile lines lacked alternative respiration in the tissue assayed (leaf or root), while the corresponding fertile tissue displayed a typical alternat...

BACKGROUND A number of studies have indicated regional differences in semen quality. To examine the current status in Japan, we undertook a cross-sectional study on the semen quality of fertile Japanese men for comparison with recent European results. METHODS Semen parameters of 324 fertile men from the Kawasaki/Yokohama area were investigated. The semen parameters were compared with those pu...

PURPOSE To compare pregnancy rates when women have intercourse on self-estimated high and peak fertile days and when they only have intercourse on low fertile days during the fertile window (FW). STUDY DESIGN AND METHODS We used a prospective observational cohort study design. Our convenience sample included 124 women who utilized our online charting Web sites to achieve pregnancy from Januar...

In the paper, we first present an approach to extract social networks from message boards on the Internet. Then we propose communication gaps based on structural features of the social networks as an indicator of understanding the state of communication. After we classify 3,000 social networks into three types of communication, i.e., interactive communication, distributed communication, and soa...

abstractbackground and purpose nowadays, the application of antioxidants and plant growth regulators has discussed for decreasing the negative effect of different stresses. ascorbic acid and sodium nitroprusside have substance caused witch the resistance to biotic and abiotic stresses. to evaluate the effect of ascorbic acid and sodium nitroprusside foliar application on some traits of safflowe...

HE sterility of triploids and other unbalanced polyploids is generally conT ceded to be a consequence of irregularities in the distribution of univalents and multivalents at meiosis. Occasional viable gametes are produced, however, because of nonrandom orientation and segregation of chromosome associations. Thus, SATINA and BLAKESLEE (1937a, b) found a higher frequency of n and 2n chromosome nu...

We present a deep, high spatial resolution (0.35 arcsec FWHM), near-infrared (1–2.5 μm) imaging survey of the Eagle Nebula, M 16, made with the VLT, centred on the famous elephant trunks. We compare these data with the existing HST optical images to search for evidence of ongoing or recent star formation in the trunks, and in particular in the 73 small evaporating gaseous globules (EGGs) on the...
