Arginine kinase (AK) was isolated from the body wall muscle of the primitive sea anemone Anthopleura japonicus by Ultrogel AcA34 gel filtration, DEAE-32 chromatography and elution on a Cosmogel-SP column. The denatured molecular mass as determined with SDS/PAGE was 80 kDa, twice that of the usual AK subunit, indicating that this AK has an unusual two-domain structure. The native form was eluted...

5aAB1. A comparison of acoustic and visual metrics of sperm whale longline depredation. Aaron Thode (SIO, UCSD, 9500 Gilman Dr., MC 0238, La Jolla, CA 92093-0238, [email protected]), Lauren Wild (Sitka Sound Sci. Ctr., Sitka, AK), Delphine Mathias (GIPSA Lab., Grenoble INP, St. Martin d’Hères, France), Janice Straley (Univ. of Alaska Southeast, Sitka, AK), and Chris Lunsford (Auke Bay Labs., NOAA...

Let a1,a2,…,ak be positive integers with gcd(a1,a2,…,ak)=1. Frobenius number is the largest integer that NOT representable in terms of a1,a2,…,ak. When k?3, there no explicit formula general, but some formulae may exist for special sequences a1,a2,…,ak, including, those forming arithmetic progressions and their modifications. In this paper, we give power weighted sum nonrepresentable integers. ...

A failure-informed enrichment algorithm is devised to improve the performance of existing adaptive Kriging-probability density evolution method (AK-PDEM) for reliability analysis. This improved named AK-PDEMi. Contrary empirically prescribing sample size representative points in AK-PDEM, point set AK-PDEMi sequentially enriched by new sets generated a scheme, which aims making fine partitions k...

The aim of this study was to compare the effect of corneal irregularity on astigmatism assessment using automated keratometry (AK) (IOLMaster) versus ray tracing keratometry (Pentacam). This is an observational case series approved by the institutional review board of Dongguk University Hospital, Goyang, South Korea. A total of 207 eyes of 207 cataract patients were included. Preoperative corne...

Adenosine kinase (AK) is a purine salvage enzyme that catalyzes the phosphorylation of adenosine to AMP. In Mycobacterium tuberculosis, AK can also catalyze the phosphorylation of the adenosine analog 2-methyladenosine (methyl-Ado), the first step in the metabolism of this compound to an active form. Purification of AK from M. tuberculosis yielded a 35-kDa protein that existed as a dimer in its...

Aspartate kinase (AK, EC 2.7.2.4) and homoserine dehydrogenase (HSDH, EC 1.1.1.3) have been partially purified and characterised from immature sorghum seeds. Two peaks of AK activity were eluted by anion-exchange chromatography [diethylaminoethyl (DEAE)-Sephacel] with 183 and 262 mM KCl, and both activities were inhibited by lysine. Similarly, two peaks of HSDH activity were eluted with 145 and...

BACKGROUND Photodynamic therapy with daylight (DL-PDT) is efficacious in treating actinic keratosis (AK), but the efficacy of field-directed, repetitive DL-PDT for the treatment and prophylaxis of AK in photodamaged facial skin has not yet been investigated. METHODS/DESIGN In this multicenter, prospective, randomized, controlled, two-armed, observer-blinded trial, patients with a minimum of 5...
