in multi-step organic syntheses, the protection and deprotection of tetrahydropyranyl (thp) ethers is one of the most frequently used methods. over the years, different methods have been used from various catalytic systems for the protection of hydroxyl groups as thp ethers and their deprotection. herein we have reported that various alcohols and phenols have been efficiently converted to the c...

Five human malignant non-T lymphoid cell lines have been established. THP-4 and THP-7 were derived from two children with common type acute lymphoblastic leukemia (ALL), THP-6 and THP-8 from two children with null cell type ALL and THP-9 from a child with malignant lymphoma. THP-4 was positive for cytoplasmic mu, B4, common ALL antigen (CALLA) and Ia-like antigen (Ia), THP-7 positive for B4, CA...

The aim of the present work was to develop a simple and rapid method for determination of theophylline (THP) and guaifenesin (GU) in syrup without involving any preparation operations like separation or masking. A HPLC and two spectrophotometric methods based on the derivation of the main spectra are described for the determination of THP and GU in combined pharmaceutical syrup form. The first ...

Many signaling or data forwarding operations involve the broadcasting of packets, which incurs considerable collisions in ad hoc networks based on a contention-based channel access protocol. We propose the Threehop Horizon Pruning (THP) algorithm to compute two-hop connected dominating set (TCDS) using only local topology information (i.e., two-hop neighborhood). Because every node has the two-...

BACKGROUND Pirarubicin (THP), an analogue of doxorubicin, has exhibited promising activities against acute leukemia, malignant lymphoma, and several solid tumors. However, the cumulative cardiotoxicity limits its wide application in chemotherapy. METHOD To provide an alternative strategy for reducing the cardiotoxicity, a novel THP liposome powder (L-THP), comprising distearoylphosphatidylcho...

Tamm-Horsfall protein (THP) is a glycoprotein with unclear functions expressed exclusively in thick ascending limbs (TAL) of the kidney. Its role in ischemic acute kidney injury is uncertain, with previous data suggesting a possible negative effect by enhancing cast formation and promoting inflammation. Using a recently characterized THP knockout mouse (THP-/-), we investigated the role of THP ...

OBJECTIVES Legionella species are facultative intracellular bacteria. Evaluation of the activity of antibiotics against intracellular L. pneumophila is more predictive of their in vivo efficacy than MICs as determined in axenic medium. However, current methodologies are based on cfu count determination, and are tedious because of the slow growth of Legionella spp. We investigated antibiotic sus...

Tamm-Horsfall protein (THP) is an abundant urinary protein of renal origin. We hypothesize that THP can act as an inhibitor of complement since THP binds complement 1q (C1q) of the classical complement pathway, inhibits activation of this pathway, and is important in decreasing renal ischemia-reperfusion injury (a complement-mediated condition). In this study, we began to investigate whether TH...

Bence Jones proteins (BJPs) are the major pathogenic factor causing cast nephropathy ("myeloma kidney") by coaggregation with Tamm-Horsfall glycoprotein (THP). Understanding the interaction between these proteins is therefore important in developing treatment strategies to prevent renal failure from cast formation in multiple myeloma. We developed an enzyme-linked immunoassay to examine this ph...
