Primary effusion lymphoma (PEL) is a rare B-cell lymphoma caused by Kaposi's sarcoma-associated herpesvirus (KSHV). PEL is poorly responsive to standard cytotoxic chemotherapy and portends a poor survival. Consequently, new effective treatment options are urgently needed. It is known that KSHV encodes two lytic genes, ORF36 (phosphotransferase) and KSHV ORF21 (thymidine kinase), which can phosp...

This article describes the development of a procedure for the simultaneous evaluation of the activity of six different uridine diphosphate (UDP)-glucuronyltransferases (UGTs) in human liver microsomes (HLMs). The method consists of incubations of probe substrates for UGT1A1 (etoposide), UGT1A3 (chenodeoxycholic acid), UGT1A4 (trifluoperazine), UGT1A6 (serotonin), UGT1A9 (mefenamic acid), and UG...

Abstract: Background: Zidovudine (Azidothymidine, AZT) is widely used in the treatment of Acquired Immuno Deficiency Syndrome (AIDS) and related conditions, either alone or combination with other antiviral agents to combat HIV. AZT a Biopharmaceutical Classification System (BCS) class III drug has various disadvantages. Thus, potential candidate for delivery via lipid-based system. Materials Me...

We describe a patient who presented with cryptococcosis and the adult respiratory distress syndrome (ARDS) as the initial manifestation of the acquired immunodeficiency syndrome. This patient represents the first reported recovery from ARDS secondary to widespread cryptococcosis. He is currently doing well as an outpatient on maintenance therapy with amphotericin B and azidothymidine.

The prevalence of nucleoside reverse-transcriptase inhibitor (NRTI) mutations was determined among 95 human immunodeficiency virus-infected Thai children who were treated with dual nucleoside reverse-transcriptase inhibitors. Almost all children had resistance to at least 1 NRTI, and approximately half of the children had resistance to multiple NRTIs. Cross-resistance to stavudine and azidothym...

The release of azidothymidine from macromolecular prodrugs was designed to respond to the intracellular disulfide reshuffling. This drug has no thiol groups, and a response to this trigger was engineered using a self-immolative linker. The resulting formulations were fast-acting, efficacious, and highly potent with regards to suppressing the infectivity of the virus.

Platinum extraction from spent reforming catalysts in iodine solutions under atmospheric pressure at different temperatures, acid concentration, and iodine spices concentration, catalyst particle size, and impeller agitation speed have been studied in our group. In this system, platinum is oxidized from spent catalyst with I3¯ that is formed ...
