Mycorrbizal symbiosis is critical to growth of many warmseason prairie grass seedlings, but its effect on regrowth of rbizomes has not been determined. As forage species, the effect of grazing on the symbiosis is also important. when the impact of mycorrbizae on regrowth of Andropogon germ&i Vit. rhizomes was assessed, A. germ& rhizomes collected from the field and grown with mycorrbizal inocul...

A common approach for color image processing is to rst transform the RGB image to a new color space (such as LHS and YIQ), do the processing, and then transform back to RGB space. In many applications, only the luminance component is processed, and the hue and saturation are preserved. However, when the processed values in the new color system are transformed back to RGB, the transformed values...

BACKGROUND AND PURPOSE The purpose of this study was to analyze the 3-month outcomes of patients with aneurysmal subarachnoid hemorrhage (SAH) treated from January 2005 to June 2006. This paper describes the outcomes after treatment of aneurysmal SAH and comparison between patients treated by clipping or coiling in a high volume center. MATERIALS AND METHODS A retrospective chart review was p...

Jugular venous compression by the Queckenstedt's test (Q-test) increases the intracranial pressure, but the effects of isolated jugular venous congestion are not well known. Intraventricular pressure (IVP) was compared during direct obstruction of the common jugular veins (bilateral CJV clipping) and during external compression of bilateral CJV flows (Q-test) in a rat model. Intracerebroventric...

PURPOSE To evaluate the efficacy and stability of the wrap-clipping methods as a reconstructive strategy in the treatment of unclippable cerebral aneurysms. MATERIALS AND METHODS Twenty four patients who had undergone wrap-clipping microsurgery were retrospectively reviewed. Type and morphology of the treated aneurysm, utilized technique for wrap-clip procedure, and clinical outcome with angi...

BACKGROUND There is wide regional variation in the predominant treatment for unruptured cerebral aneurysms. We investigated the association of elective surgical clipping and endovascular coiling with mortality, readmission rate, length of stay, and discharge to rehabilitation. METHODS AND RESULTS We performed a cohort study involving patients with unruptured cerebral aneurysms, who underwent ...

While complete neck clipping of ruptured cerebral aneurysms prevents rerupture, recurrent subarachnoid hemorrhage (SAH) due to the rupture of an aneurysm at the same sites of the previous aneurysm may occur, even if no residual neck was detected during and after neck clipping. We present the cases of 3 patients with recurrent SAH due to regrowth after neck clipping of aneurysms at the anterior ...

BACKGROUND Publication bias and/or true heterogeneity can skew aggregate impressions from scientific literature. To better determine aggregate measures for unruptured intracranial aneurysm (UIA) treatment, we analyzed adverse outcome rates of surgical clipping and endovascular coil embolization. METHODS Two independent reviewers searched MEDLINE for studies publishing adverse outcome rates fo...

This paper work focuses on performance analysis of PAPR reduction of orthogonal frequency division multiplexing (OFDM) using amplitude clipping & filtering based design. Now a days one of the most proficient multi-carrier transmission techniques widely used today is orthogonal frequency division multiplexing (OFDM) which has been implemented by the next generation wireless communication technol...

OBJECTIVE The purpose of this study was to determine the outcomes of surgical clipping in patients with unruptured middle cerebral artery (MCA) aneurysms. METHODS A retrospective single-center database of 125 consecutive patients with 143 small MCA aneurysms (< 10 mm) who underwent surgical clipping was reviewed from January 2007 to December 2010. Clinical outcomes were assessed based on surg...
