We examined the relationship between anterior knee laxity (AKL), evaluated while the knee was nonweight bearing, and anterior translation of the tibia relative to the femur (ATT), evaluated when the knee transitioned from nonweight-bearing to weight-bearing conditions in response to an applied compressive load at the foot. Twenty subjects with normal knees (10 M, 10 F; 25.2 ± 4.1 years, 169.8 ±...

PURPOSE The importance of arterial transit time (ATT) correction for arterial spin labeling MRI has been well debated in neuroimaging, but it has not been well evaluated in renal imaging. The purpose of this study was to evaluate the feasibility of pulsed continuous arterial spin labeling (pcASL) MRI with multiple post-labeling delay (PLD) acquisition for measuring ATT-corrected renal blood flo...

BACKGROUND Adenotonsillectomy (ATE) is a well-established and effective treatment of pediatric obstructive sleep apnea (OSA). In recent years, a more conservative method, adenotonsillotomy (ATT), has gained popularity because it is associated with less postoperative morbidity. Yet no previous randomized study has compared these 2 methods regarding their effectiveness in treating pediatric OSA i...

This case-control study followed by a longitudinal cohort study was undertaken to evaluate the level of lipid peroxidation product malondialdehyde (MDA) and nitrite as an indirect measurement of nitric oxide vis-à-vis the levels of antioxidants vitamin C and vitamin E in pulmonary tuberculosis. Fifty-six sputum smear-positive cases of pulmonary tuberculosis based on Ziehl-Neelsen (ZN) staining ...

I denna avhandling studeras prostatacancerns naturalförlopp och värdet av befi ntliga prognostiska faktorer. Man studerar också några nya tänkbara prognostiska faktorer. Dessutom tittar man på tids trender för prostata tumörer som är upptäckta incidentalt vid två olika typer av operationer, som görs vid vattenkastningsbesvär. Avhandlingen bygger på två unika prostata cancer material som samlats...

We describe the isolation of a variant of Mu transposase (MuA protein) which can recognize altered att sites at the ends of Mu DNA. No prior knowledge of the structure of the DNA binding domain or its mode of interaction with att DNA was necessary to obtain this variant. Protein secondary structure programs initially helped target mutations to predicted helical regions within a subdomain of MuA...

background: interferon gamma (ifn-γ), a cytokine produced by a variety of cells is involved in the immune response against m. tuberculosis. it activates the production of other cytokines and molecules that kill mycobacterium. ifn-γ also has diagnostic role in identification of active and latent tuberculosis. objective: to determine the level of ifn-γ in the blood of tb patients. methods: ninety...
