Moderate disturbances and shrub protection enhance perennial grass recruitment in northern Patagonia
Herbivory and fire promote changes in vegetation patches of arid environments, recruitment plays a key role their maintenance. We studied seedling dynamics seven sites with different land use histories related to grazing north-eastern Patagonian Monte, Argentina. selected shrub grazed/burned areas. On each patch, we established microsites along an under-canopy windward/leeward transect. Seedlin...
BACKGROUND Breast cancer is associated with a relatively good prognosis. Prognostic factors examined to date are related to early recurrence while those related to late recurrence and their countermeasures remain unclear. Therefore, we examined the factors related to late recurrence. PATIENTS AND METHODS From January 1980 to August 2012, 4,774 patients who underwent primary treatment and estr...
Basal-like breast cancer, an aggressive subtype associated with high grade, poor prognosis, and younger age, is reported frequently in Africa. We analyzed the expression of the basal cytokeratins (CKs) 5/6 and 17 in a case series from Central Sudan and investigated correlations among basal CK status, ER, PgR, and Her-2/neu, and individual/clinicopathological data. Of 113 primary breast cancers ...
OBJECTIVES The aim of the study was to estimate the implications of androgen receptor (AR) expression in estrogen receptor (ER)-positive subset of invasive breast carcinoma patients. PATIENTS AND METHODS We assessed the AR expression in a subset of 96 predominantly ER-positive invasive breast carcinomas and correlated this expression pattern with several clinical and pathologic parameters: hi...
A series of experiments were conducted in 2003 in the Upper Gila River Valley in Safford, AZ to evaluate several different formulations of the plant growth regulator (PGR) Pix manufactured by BASF. Two experiments were conducted at the Safford Agricultural Center (SAC) while the third was conducted on a grower-cooperator field in the same valley. Experiments conducted at SAC involved evaluating...
BACKGROUND Analysis of estrogen receptor (ER), progesterone receptor (PgR) and HER2 status in early breast cancer (EBC) is increasingly being conducted in core needle biopsies (CNBs) taken at diagnosis but the concordance with the excisional biopsy (EB) is poorly documented. PATIENTS AND METHODS Patients with EBC presenting to The Royal Marsden Hospital from June 2005 to September 2007 who ha...
PURPOSE Patients with hormone receptor-negative breast cancer generally do not benefit from endocrine-targeted therapies. However, a subset with androgen receptor (AR) expression is predicted to respond to antiandrogen therapies. This phase II study explored bicalutamide in AR-positive, estrogen receptor (ER), and progesterone receptor (PgR)-negative metastatic breast cancer. EXPERIMENTAL DES...
Abstract The Potential Grasp Robustness (PGR) metric considers different states of the contact points, relaxing requirement all points being far from friction cone boundary. addition new for each point increases computational complexity, which is combinatorial on number and takes a long time grasping configurations with large hand-object contacts. In this work we analyse complexity two recently...
The sea lamprey (Petromyzon marinus) represents one of the few vertebrate species known to undergo large-scale programmatic elimination of genomic DNA over the course of its normal development. Programmed genome rearrangements (PGRs) result in the reproducible loss of ~20% of the genome from somatic cell lineages during early embryogenesis. Studies of PGR hold the potential to provide novel ins...
A total of 725 human primary breast tumor biopsy samples were analyzed for epidermal growth factor receptor (EGFR) content, using a multiple-point EGFR assay standardized in accordance with the recom mendations of the European Organization for Research and Treatment of Cancer Receptor Study Group. After the establishment of a lower cell membrane protein threshold of 0.2 mg of membrane protein p...
