Juvenile Nile crocodiles (Crocodylus niloticus) and spectacled caimans (Caiman crocodilus) use water surface waves for the detection of prey, usually insects trapped at the water surface. This prey detection relies on mechanosensors, the integumentary sensory organs. We found by go/no go conditioning that C. niloticus and C. crocodilus can discriminate surface waves that differ in frequency. On average, frequency difference thresholds were about 4-5 %, e.g. C. niloticus and C. crocodilus distinguished a 40 Hz surface wave from a 38,5 Hz surface wave stimulus. C. niloticus and C. crocodilus also discriminated between single-frequency surface waves (15 Hz or 40 Hz) and surface waves that showed an abrupt frequency change (e.g. from 15 to 16.5 Hz or from 40 Hz to 38.5 Hz). The threshold for the abrupt frequency changes averaged 3-9 %. Additionally, Nile crocodiles differentiated also between a single-frequency water surface wave and a water surface wave that was amplitude modulated. C. niloticus also determined the direction (mean error angle between 13,7° and 16,6°) to a surface wave stimulus. Furthermore, the distance covered by the Nile crocodiles increased slightly with increasing source distance. This was true whether a single-frequency (15 Hz or 40 Hz, relative distance error between 36 and 37%) or a multi-frequency (band width 1 - 80 Hz, relative distance error 25%) surface wave stimulus was offered. Even if the rewarded stimulus (40 Hz) was superimposed by an unrewarded surface wave some distance determination was observed (relative distance error between 30 and 62%). PURPOSE To compare the prevalence of enlarged ovarian and intrapelvic parasitic arteries to the gravid uterus between cases of placenta accreta spectrum (PAS) and those with normal placentation using unenhanced magnetic resonance (MR) angiography. METHODS Unenhanced time-of-flight MR angiography was performed in 12 consecutive women with PAS (mean age, 34 years; range, 23-42 years) and 24 women with normal placentation (mean age, 31 years; range, 24-42 years) in their third trimester and reviewed by two independent observers. The consensus reading served as the reference standard. Findings of pelvic arteriography performed at cesarean hysterectomy were reviewed in all cases of PAS. The prevalence of enlarged ovarian and intrapelvic parasitic arteries was compared using Fisher's exact test. The interobserver agreement was assessed with Kappa statistics. RESULTS The prevalence of enlarged ovarian arteries was not significantly different between cases of PAS and normal placentation (17% [4/24 pelvic sides] vs. 4% [2/48 pelvic sides], P = .091). The prevalence of intrapelvic parasitic arteries was significantly higher in cases of PAS than in those with normal placentation (67% [16/24 pelvic sides] vs. learn more 0% [0/48 pelvic sides], P less then .0001). On a patient-by-patient basis, the intrapelvic parasitic artery was frequently present in women with PAS (92% [11/12 patients]). The Kappa values were 0.915 and 0.852 for detecting enlarged ovarian and intrapelvic parasitic arteries, respectively, indicating excellent interobserver agreement. CONCLUSIONS The development of intrapelvic parasitic arteries was an anomalous phenomenon observed on unenhanced MR angiography in the majority of women with PAS but was not observed in those with normal placentation. Virtually all transport events at the Golgi complex are regulated by Arf and Rab family GTPases. Recent work has advanced our knowledge regarding the mechanisms controlling GTPase activity, and it has become clear that GTPases do not act in isolation but rather function in complex networks of crosstalk and feedback. Together with earlier findings, these recent studies indicate that communication between GTPases, their regulatory proteins, effectors, and lipids plays a pivotal role in Golgi transport and cisternal maturation. A tracking and reporting system was developed to monitor radiation dose in X-ray breast imaging. We used our tracking system to characterize and compare the mammographic practices of five breast imaging centers located in the United States and Brazil. Clinical data were acquired using eight mammography systems comprising three modalities computed radiography (CR), full-field digital mammography (FFDM), and digital breast tomosynthesis (DBT). Our database consists of metadata extracted from 334,234 images. We analyzed distributions and correlations of compressed breast thickness (CBT), compression force, target-filter combinations, X-ray tube voltage, and average glandular dose (AGD). AGD reference curves were calculated based on AGD distributions as a function of CBT. These curves represent an AGD reference for a particular population and system. Differences in AGD and imaging settings were attributed to a combination of factors, such as improvements in technology, imaging protocol, and patient demographics. The tracking system allows the comparison of various imaging settings used in screening mammography, as well as the tracking of patient- and population-specific breast data collected from different populations. BACKGROUND Articles concerning the correlation of the risk of chronic kidney disease (CKD) with air contaminant exposure present inconsistent findings and the magnitude of the link is still unclear. Therefore, we planned to systematically and quantitatively investigate the overall strength of proofs in this field. METHODS Relevant articles on Cochrane, EMBASE, Medline, Web of Science, and CINHAL were searched as per relevant strategies. Only observational studies that disclosed the link of CKD risk with major air pollutants were enrolled, including PM10 and PM2.5, which were particulate matter less than 10 um and less than 2.5 um in erodynamic diameter respectively. Pooled relative risk (RR) and 95 % confidence interval (CI) were determined using random--effects models, regardless of the heterogeneity quantified by I2 statistic. RESULTS Finally, 7 studies involving 5,812,381 participants were included. The incidence of CKD was increased by long-term exposure to PM10 (including solely estimated exposure to PM10 from studies using PM2.
