Most proteins encoded by members of the Ly-49 gene family are class I-recognizing receptors on murine natural killer (NK) cells. Class I recognition by Ly-49 receptors usually results in inhibition of NK cell lysis of target cells. However, NK cells function not only in a lytic capacity, but also can mediate cytokine production. In this report we have demonstrated the ability of Ly-49A and Ly-4...

The mouse T-lymphoma (S-49) cell line is useful for individually studying RNA- and DNA-directed effects of 5-fluoropyrimidines. On the basis of their metabolic activation, biochemical effects on pyrimidine nucleotide metabolism, and biological toxicity, we hve established that incubation of S-49 cells with 5-fluorodeoxyuridine produces only DNA-directed toxicity (thymidylate synthetase inhibiti...

STUDY OBJECTIVES To compare the results of open myomectomy with those of laparoscopic myomectomy, and to assess complications, surgical results, total hospital cost, and morbidity associated with each procedure. DESIGN Retrospective chart review. SETTING Private practice of one surgeon, and Department of Obstetrics and Gynecology, Rush Medical College, Chicago, Illinois. PATIENTS Ninety-e...

In recent years, a plethora of theoretical carbon allotropes have been proposed, none of which has been experimentally isolated. We discuss here criteria that should be met for a new phase to be potentially experimentally viable. We take as examples Haeckelites, 2D networks of sp(2)-carbon-containing pentagons and heptagons, and "penta-graphene," consisting of a layer of pentagons constructed f...

Torularhodin is a fungus-derived carotenoid, and the lack of downstream processing torularhodin still challenge for its large-scale production. To support industrial production torularhodin, this work initially evaluated efficiency carotenoid release from Rhodotorula mucilaginosa using thermal acid treatment, saponification ultrasound-assisted enzymatic lysis. Based on polarity, was then purifi...
