Ammonia-oxidizing archaea (AOA) within the phylum Thaumarchaeota are the only known aerobic ammonia oxidizers in geothermal environments. Although molecular data indicate the presence of phylogenetically diverse AOA from the Nitrosocaldus clade, group 1.1b and group 1.1a Thaumarchaeota in terrestrial high-temperature habitats, only one enrichment culture of an AOA thriving above 50°C has been r...
I late 2011, the Accreditation Council for Graduate Medical Education (ACGME) announced proposed changes to their Common Program Requirements, which are requirements that must be met by all ACGME residency and fellowship programs regardless of specialty. The proposed changes would have limited the ability of osteopathic physicians with graduate medical education (GME) training through a program...
World Health Organization (WHO) grade 3 glioma is one of the common brain tumors and has three main histological subtypes, including anaplastic astrocytoma (AA), anaplastic oligoastrocytoma (AOA) and anaplastic oligodendroglioma (AO). However, most previous studies have considered AOA and AO as one group because of the difficult differential diagnosis between AOA and AO. Therefore the prognosti...
Soil ammonia oxidizing bacteria (AOB) and archaea (AOA) are responsible for nitrification in terrestrial ecosystems, and play important roles in ecosystem functioning by modulating the rates of N losses to ground water and the atmosphere. Vascular plants have been shown to modulate the abundance of AOA and AOB in drylands, the largest biome on Earth. Like plants, biotic and abiotic features suc...
Background: Failed fertilization after intracytoplasmic sperm injection (ICSI) can be due to a reduced oocyte-activation capacity caused by reduced concentrations and abnormal localization of the oocyte-activation factor phospholipase C (PLC) zeta. Patients with this condition can be helped to conceive by artificial activation of oocytes after ICSI with calcium ionophore (assisted oocyte activa...
Objective: In this study, we plan to measure plasma Catalase (CAT), Antioxidant Activity (AOA) and Glutathione-S-Transferase (GST) levels to understand whether oxidative stress develops or not and whether or not the detoxification mechanism properly functions in children with Attention Deficit and Hyperactivity Disorder (ADHD) with unknown etiology and pathogenesis. Method and Results: Plasma C...
Background Failed fertilization occurs 1-3% in the infertile couples. Failure of oocyte activation (OA) is mainly attributed to failed fertilization. ICSI alone artificial oocyte activation (AOA) is only treatment approach for these individuals. Three procedures are introduced for AOA: chemical, mechanical and electrical. Most of the clinical Centers have commonly used ionomycin for activation ...
BACKGROUND Aortic Atheroma (AoA) is an independent risk factor for new and recurrent stroke. AoA ulceration and mobility are associated with an increased risk for brain embolism. Transesophageal echocardiography (TEE) is the gold standard for detection and measurement of AoA in stroke/TIA patients. Cardiovascular MRI (cMRI) could be an alternative, non-invasive imaging modality for stroke/TIA p...
Community composition and abundance of ammonia-oxidizing archaea (AOA) in the ocean were affected by different physicochemical conditions, but their responses to physical barriers (such as a chain of islands) were largely unknown. In our study, geographic distribution of the AOA from the surface photic zone to the deep bathypelagic waters in the western subarctic Pacific adjacent to the Kuril I...
