In Beaufort Street they only learnt that Waymark had not yet been home. Thence they drove to the east, and stopped at a police-station, where Abraham saw the inspector. The latter suggested that Mr. Woodstock should go through all the houses which Waymark would have visited; if that search proved fruitless, the police would pursue the matter. Ida insisted on being allowed to accompanying him when the cab stopped at the end of Litany Lane. She gazed about her like one who had been suddenly set down in a new country; this squalor and vileness, so familiar to her of old, affected her strangely under the present conditions. The faces of people at whom she looked remained fresh in her memory for years after; the long confinement and the excitement which now possessed her resulted in preternatural acuteness of observation. Abraham spoke first with several people whom he had already questioned about Waymark, but they had heard nothing since. "Are you strong enough for this?" he asked Ida. "Hadn't you better go back to the cab and wait for.

This method employs a body-fitted grid system where the gas-liquid interface is one line of the grid system. Based on a Finite-Volume formulation, complicated dynamic boundary conditions are incorporated naturally and accurately in our ALE method. The resulting nonlinear system of mass and momentum conservation is therefore solved by a projection method. As far as the physics is concerned, we employ a non-linear Langmuir model to determine the surfactant equation of state. For simplicity, we limit ourself to the situation of an insoluble surfactant. We consider two popular nonlinear constitutive equations for the viscoelastic liquid: the FENE-CR model and the Giesekus model. We study the effect of surfactant on bubble deformation in an uniaxial extensional flow of moderate Reynolds number between 10 and 100 , with emphasis on the transition from a slip to no-slip boundary condition on the gas-liquid interface. Finally, we report our results on bubble rising in a quiescent polymer solution, including the phenomenon of the negative wake. 9: 05 KF The effect of surfactant on the pinch off of a drop moving through a constriction SCOTT WILLIAMS, ASHLEY J. JAMES, University of Minnesota A computational method was developed to simulate the axisymmetric, pressure driven motion of a drop through a tube with a step constriction. The interface motion is computed using a volume of fluid method and surface tension is included as a continuum surface force. Insoluble surfactant is included in some cases using a new continuum formulation. As the drop approaches the constriction, the leading edge accelerates and the drop deforms. The trailing edge accelerates later, eventually catching up to the leading edge, which decelerates downstream of the constriction. In the process, the drop may pinch off at the trailing edge, forming one or more smaller satellite drops. Pinch off is primarily dependent on the surface tension and the constriction to drop diameter ratio. When insoluble surfactant is present it accumulates at the trailing edge of the drop, allowing greater deformation there than in the clean case. Thus, adding surfactant changes the drop evolution and the pinch off process, effecting whether satellites form, the pinch off time, and the satellite drop sizes. 9: 18 KF Lattice-Boltzmann simulations of non-deformable bubble suspensions at moderate Reynolds numbers XIAOLONG YIN, Graduate Student, Chemical and Biomolecular Engineering, Cornell University ROLF VERBERG, Postdoctoral Research Associate, Chemical and Biomolecular Engineering.

Merck's HIV clinical research program began in 1985. Merck scientists were among the first to discover and develop medicines for the treatment of HIV AIDS. In 1996, Merck introduced CRIXIVAN indinavir sulfate ; , a protease inhibitor, which was followed by the introduction in 1999 of STOCRIN efavirenz ; , a non-nucleoside reverse transcriptase inhibitor. Today, Merck remains focused on developing new treatments for millions of individuals who are already infected with HIV, as well as on preventing HIV transmission through the development of a vaccine. I Merck is in Phase III clinical studies for MK-0518, which belongs to a new class of investigational antiretroviral therapy agents called integrase inhibitors that inhibit the insertion of the HIV viral DNA into human DNA. Merck has established a worldwide expanded access program for MK-0518 for HIV AIDS patients with limited or no treatment options. Merck scientists have been conducting research to develop an HIV AIDS vaccine for nearly 20 years. Merck currently is testing vaccine candidates in phase I and phase II clinical studies and irinotecan. MATERIALS AND METHODS Samples. The cryopreserved plasma samples used in the present study were obtained from patients infected with HIV who were participating in a clinical trial with i ; indinavir at a dose of 600 mg four times a day patients H and P ; or ii ; the same therapy combined with interleukin-2 that is given by continuous infusion for 5 days every 2 months patients A and L ; 15 ; . The patients had previously received nucleoside analogs. Patients on the first regimen were permitted to switch to combination therapy with interleukin-2 and other antiretroviral agents after 12 weeks. Samples obtained from 10 patients before receiving indinavir therapy were used to analyze the preexisting mutations. All subjects provided written informed consent and the protocol was approved by the institutional review board of the National Institute of Allergy and Infectious Diseases. RNA isolation and cDNA synthesis. HIV-1 RNA was isolated from 260 l of plasma by using the QIAamp HCV kit Qiagen Inc., Chatsworth, Calif. ; . HIV-1 RNA was reverse transcribed to cDNA by using oligonucleotide primer A and avian myelobastosis virus reverse transcriptase Invitrogen Corporation, San Diego, Calif. ; . The primers used for cDNA synthesis and PCR amplification are listed in Table 1. PCR. The HIV-1 protease gene sequence was amplified by PCR with a mixture of Klentaq1 Ab Peptides, Inc., St. Louis, Mo. ; and Pfu Stratagene, La Jolla, Calif. ; DNA polymerases 2 ; and the B-C primer pair. Nested PCR was carried. Adult AIDS Clinical Trials Group 5043 examined pharmacokinetic PK ; interactions between amprenavir APV ; and efavirenz EFV ; both by themselves and when nelfinavir NFV ; , indinavir IDV ; , ritonavir RTV ; , or saquinavir SQV ; is added. A PK study was conducted after the administration of single doses of APV day 0 ; . Subjects n 56 ; received 600 mg of EFV every 24 h q24h ; for 10 days and restarted APV with EFV for days 11 to 13 with a PK study on day 14. A second protease inhibitor PI ; NFV, 1, 250 mg, q12h; IDV, 1, 200 mg, q12h; RTV, 100 mg, q12h; or SQV, 1, 600 mg, q12h ; was added to APV and EFV on day 15, and a PK study was conducted on day 21. Controls continued APV and EFV without a second PI. Among subjects, the APV areas under the curve AUCs ; on days 0, 14, and 21 were compared using the Wilcoxon signed-rank test. Ninety-percent confidence intervals around the geometric mean ratios GMR ; were calculated. APV AUCs were 46% to 61% lower median percentage of AUC ; with EFV day 14 versus day 0; P values of 0.05 ; . In the NFV, IDV, and RTV groups, day 21 APV AUCs with EFV were higher than AUCs for EFV alone. Ninety-percent confidence intervals around the GMR were 3.5 to 5.3 for NFV P 0.001 ; , 2.8 to 4.5 for IDV P 0.001 ; , and 7.8 to 11.5 for RTV P 0.004 ; . Saquinavir modestly increased the APV AUCs GMR, 1.0 to 1.4; P 0.106 ; . Control group AUCs were lower on day 21 compared to those on day 14 GMR, 0.7 to 1.0; P 0.042 ; . African-American non-Hispanics had higher day 14 efavirenz AUCs than white non-Hispanics. We conclude that EFV lowered APV AUCs, but nelfinavir, indinavir, or ritonavir compensated for EFV induction. The clinical use of antiretroviral regimens containing combinations of nucleoside reverse transcriptase inhibitors NRTIs ; , non-nucleotide reverse transcriptase inhibitors NNRTIs ; , and protease inhibitors PI ; has become the accepted approach to therapy for human immunodeficiency virus HIV ; infection, especially for patients with multiple prior antiretroviral regimens 1, 29 ; . This has led to the development of new antiretroviral treatments and clinical studies of three- and four-drug combinations as salvage regimens for antiviral-experienced patients. While these combination regimens are often guided by HIV-1 resistance assays, there are often incomplete pharmacokinetic PK ; data available to guide optimal dosing of dual protease inhibitors in an NNRTI-containing regimen. Due to the complex nature of drug interactions metabolic induction versus inhibition, efflux transporter interactions ; and the desire to understand mechanisms underlying these drug interactions, Adult AIDS Clinical Trials Group ACTG ; protocol A5043 was developed to examine these interactions. At the time A5043 was developed, the routine use of low-dose ritonavir RTV ; was not considered to be the standard of care, and the optimal approach to combining two PIs with efavirenz EFV ; was under investigation in ACTG 398. ACTG 398 utilized NNRTI-PI combinations similar to those of ACTG 5043 along with nucleoside analogs and reported 30% antiviral responses in a group of PI-experienced patients 10 ; . Another clinical study was conducted in a small group of patients with HIV-1 infection, examining two dosage regimens of reduceddose ritonavir in combination with amprenavir APV ; , efavirenz, and NRTIs, indicating that efavirenz induction could be offset by ritonavir 6 ; . The pharmacologic objective of ACTG 5043 was to extend these studies and obtain additional data on indinavir IDV ; -, nelfinavir NFV ; -, and saquinavir SQV ; containing regimens and their dosage requirements when combined with amprenavir and efavirenz in HIV-seronegative subjects. In addition, the inclusion of a control group that did not have a second PI added allowed for comparison against results obtained by continued efavirenz and amprenavir dosing. The rationale for conducting ACTG 5043 in HIV-seronegative volunteer subjects was that stepwise introduction of a second PI to the combination of amprenavir plus efavirenz could be accomplished without the concern of drug concentrations being less than therapeutic, which might put HIV-in3373 and isdn.
