OBJECTIVE To investigate the relationship between tonsillar and peritonsillar infections. STUDY DESIGN Retrospective population-based study and a retrospective case series review. SETTINGS Tertiary academic medical facility. SUBJECTS AND METHODS All individuals hospitalized with peritonsillar abscess (PTA) or peritonsillar cellulitis (PTC) during 2004-2008 were reviewed. Patient age, gend...

BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty (PTA) is currently being assessed for the treatment of carotid stenosis. In comparison with carotid endarterectomy (CEA), there is evidence of an increased risk of cerebral microembolism during the procedure. We have sought evidence of any neuropsychological sequelae of carotid PTA and compared it with CEA to demonstrate the relative ...

BACKGROUND AND PURPOSE When medication fails to improve symptoms of atherosclerotic stenosis of the intracranial vertebral and basilar arteries, percutaneous transluminal angioplasty (PTA) is considered. However, because investigators disagree on the usefulness of this procedure, we conducted a retrospective study to evaluate the indications, efficacy, and safety of PTA. METHODS Twenty patien...

Atypical lymphocytes from nine young adults with acute infectious mononucleosis (IM) were studied for morphologic, ultrastructural, cytochemical, and membrane surface marker characteristics. There was an absolute increase in T lymphocytes in the patients. Atypical lymphocytes accounted for 83%-96% of the lymphocyte population. These lymphocytes contained cytoplasmic inclusions which ranged in s...

Triticum genus encloses several tetraploid species that are used as genetic stocks for expanding the genetic variability of wheat (Triticum aestivum L.). Although the T. aestivum (2n = 6x = 42, AABBDD) and T. durum (2n = 4x = 28, AABB) karyotypes were well examined by chromosome staining, Giemsa C-banding and FISH markers, other tetraploids are still poorly characterized. Here, we established a...

Objectives Patients with sudden sensorineural hearing loss (SSNHL) may have word recognition scores (WRS) that correlate with pure tone average (PTA). We hypothesize that there is a subset of patients with SSNHL who have improved WRS despite stable PTA. Methods Retrospective case review at a tertiary otolaryngology practice. Results We identified 13 of 113 patients with SSNHL whose WRS incr...

Exceptionally high surface area and ordered nanopores of a metal-organic framework (MOF) are exploited to encapsulate and homogeneously disperse a considerable amount of phosphotungstic acid (PTA). When combined with platinum nanoparticles positioned on the external surface of the MOF, the construct shows a high catalytic activity for hydroisomerization of n-hexane, a reaction requiring hydroge...

In phylogenomics the analysis of concatenated gene alignments, the so-called supermatrix, is commonly accompanied by the assumption of partition models. Under such models each gene, or more generally partition, is allowed to evolve under its own evolutionary model. Although partition models provide a more comprehensive analysis of supermatrices, missing data may hamper the tree search algorithm...
