Published: August 2012

Object
The difference in the hemodynamics of wall shear stress (WSS) and oscillatory shear index (OSI) between ruptured and unruptured aneurysms is not well understood. The authors investigated the hemodynamic similarities and dissimilarities in ruptured and thin-walled unruptured aneurysm blebs.

Methods
Magnetic resonance imaging–based fluid dynamics analysis was used to calculate WSS and OSI, and hemodynamic and intraoperative findings were compared. The authors also compared ruptured and unruptured thin-walled blebs for the magnitude of WSS and OSI.

Results
Intraoperatively, 13 ruptured and 139 thin-walled unruptured aneurysm blebs were identified. Twelve of the ruptured (92.3%) and 124 of the unruptured blebs (89.2%) manifested low WSS and high OSI. The degree of WSS was significantly lower in ruptured (0.49 ± 0.12 Pa) than in unruptured (0.64 ± 0.15 Pa; p < 0.01) blebs.

Conclusions
Ruptured and unruptured blebs shared a distinctive pattern of low WSS and high OSI. The degree of WSS at the rupture site was significantly lower than in the unruptured thin-walled blebs.
Avoiding transport bottlenecks in an expanding root system: Xylem vessel development in fibrous and pioneer roots under field conditions
Authors: Bagniewska‐Zadworna Agnieszka , Byczyk Julia , Eissenstat David M. , Oleksyn Jacek , Zadworny Marcin 
Published: August 2012

• Premise of the study: Root systems develop to effectively absorb water and nutrients and to rapidly transport these materials to the transpiring shoot. In woody plants, roots can be born with different functions: fibrous roots are primarily used for water and nutrient absorption, whereas pioneer roots have a greater role in transport. Because pioneer roots extend rapidly in the soil and typically quickly produce fibrous roots, they need to develop transport capacity rapidly so as to avoid becoming a bottleneck to the absorbed water of the developing fibrous roots and, as we hypothesized, immediately activate a specific type of autophagy at a precise time of their development.• Methods: Using microscopy techniques, we monitored xylem development in Populus trichocarpa roots in the first 7 d after emergence under field conditions.• Key results: Newly formed pioneer roots contained more primary xylem poles and had larger diameter tracheary elements than fibrous roots. While xylogenesis started later in pioneer roots than in fibrous, it was completed at the same time, resulting in functional vessels on the third to fourth day following root emergence. Programmed cell death was responsible for creating the water conducting capacity of xylem. Although the early xylogenesis processes were similar in fibrous and pioneer roots, secondary vascular development proceeded much more rapidly in pioneer roots.• Conclusions: Compared to fibrous roots, rapid development of transport capacity in pioneer roots is not primarily caused by accelerated xylogenesis but by larger and more numerous tracheary elements and by rapid initiation of secondary growth.
Distribution of Low-Elevation American Pika Populations in the Northern Great Basin
Authors: Collins Gail H. , Bauman Bradley T. 
Published: August 2012

Abstract
The recent discovery that a portion of the historically described populations of American pikas Ochotona princeps in the Great Basin of North America appear to be extinct added emphasis to earlier warnings that these populations may be highly vulnerable, in particular those occurring at low elevations (&lt;2,500 m). Pikas in the Great Basin have received increased scientific interest; however, there is still little known about the distribution or number of populations throughout their range. Here we report on the discovery of several previously undescribed low-elevation pika populations in Southeast Oregon and Northwest Nevada. The average elevation of sites currently occupied by pikas was 1,993 m (range  =  1,648–2,357 m). This and other recent discoveries suggest that pikas may be more common at low elevations in portions of the northern Great Basin than previously suspected (i.e., &gt;2,500 m).

The experiences of first-time mothers with colic infants who seek help from medical professionals
Authors: Cox Leigh , Roos Vera 
Published: August 2012

The purpose of this study was to describe the experiences of first-time mothers with colic infants. The research design was qualitative, exploratory, descriptive and contextual. Data were collected by means of in-depth, semistructured, phenomenological interviews and a descriptive analysis was done. The results show that the real experience of having a baby did not meet mothers’ expectations. Furthermore, colic babies were anxiety-provoking and mothers struggled with feelings of failure. They searched for an explanation for the colic, but felt disillusioned with the medical profession. Mothers exhibited a need for a containing figure. They also reflected on their relationship with their mothers. Mothers felt ambivalent towards their babies and marital relationships became strained. Lastly, mothers renegotiated their identity. Based on the results, suggestions for mental health professions were made with regard to providing parent-child therapy, support for the mother and strengthening the marital relationship. The importance of psychological interventions was emphasised as a source of support for these mothers.

Opsomming
Die doel van hierdie studie was om die ervarings van eerstekeermoeders met koliekbabas te beskryf. Die navorsingsontwerp was kwalitatief, ondersoekend, beskrywend en kontekstueel van aard. Data is ingesamel deur middel van indiepte, semi-gestruktureerde, fenomenologiese onderhoude en ‘n beskrywende ontleding is gedoen. Die resultate het getoon dat die beleefde ervarings om ‘n koliekbaba te hê, nie aan die moeders se verwagtinge voldoen het nie. Voorts veroorsaak koliekbabas angs en moeders stry teen gevoelens van mislukking. In hul soeke na ‘n verklaring vir die koliek, voel hulle ontnugter met die mediese professie. Moeders het ‘n behoefte aan ‘n ondersteunende persoon uitgedruk en gereflekteer op hul verhouding met hulle eie ma’s. Moeders het ambivalent oor hul babas gevoel en hul huweliksverhoudings het gespanne geword. Laastens het moeders hulle identiteit as moeders heroorweeg. Op grond van die resultate word voorstelle vir professionele geestesgesondheidwerkers met betrekking tot ouer-kindterapie, ondersteuning aan die moeder en versterking van die huweliksverhouding, gemaak. Laastens word die belangrikheid van sielkundige intervensies in die hantering van koliek as ‘n hulpbron vir hierdie moeders beklemtoon.
