Selecting the appropriate rangeland improvement method is a challenging task for range managers because it requires consideration of various criteria. This study was aimed to evaluate various restoration and reclamation practices in the rangelands of Semirom-Isfahan using Multi-Criteria Decision Making (MCDM) methods. Grazing management, water point development, pit seeding, exclosure, water ...
Cheatgrass (Bromus tectorum L.) is the most widespread invasive weed in sagebrush ecosystems of North America. Restoration of perennial vegetation is difficult and land managers have often used introduced bunchgrasses to restore degraded sagebrush communities. Our objective was to evaluate the potential of ‘Vavilov’ Siberian wheatgrass (Agropyron fragile [Roth] P. Candargy) to establish on chea...
The cobblestone-area forming cell (CAFC) assay permits a direct measurement of the seeding of primitive and more mature murine hematopoietic stem cell subsets by comparing the number of CAFC in the original transplant with the number of CAFC retrieved from bone marrow (BM) and spleen after transplantation. We found no differences in seeding efficiency between the more mature and primitive CAFC ...
tissues. 0.7–0.9% of patients with a malignant tumour at any site can develop a cutaneous or subcutaneous metastasis after percutaneous procedures [2]. The duration between the onset of tumour seeding and the previous percutaneous needle biopsy has been shown to vary widely. Clinically, tumour deposits are observed as painful cutaneous or subcutaneous nodules, typically round or oval, with well...
Background and study aims Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esopha...
