AIDS therapies employing HIV protease inhibitors (PIs) are associated with changes in fat metabolism. However, the cellular mechanisms affected by PIs are not clear. Thus, the affects of PIs on adipocyte differentiation were examined in vitro using C3H10T1/2 stem cells. In these cells the PIs, nelfinavir, saquinavir, and ritonavir, reduced triglyceride accumulation, lipogenesis, and expression ...

Piscidin-1 (Pis-1) is a linear antibacterial peptide derived from mast cells of aquacultured hybrid striped bass that comprises 22 amino acids with a phenylalanine-rich amino-terminus. Pis-1 exhibits potent antibacterial activity against pathogens but is not selective for distinguishing between bacterial and mammalian cells. To determine the key residues for its antibacterial activity and those...

In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...

Antiretroviral drug combinations that include two nucleoside reverse transcriptase inhibitors and a protease inhibitor (PI) can suppress HIV replication to undetectable levels, improving the prognosis of HIV-infected individuals. The aim of therapy is complete virological suppression, with a current goal of <50 copies/mL HIV-1 RNA, in order to minimize the occurrence of drug resistance. Improve...

BACKGROUND There is little data on the safety of combining radiation therapy and human immunodeficiency virus (HIV) protease inhibitors to treat cancers in HIV-positive patients. We describe acute toxicities observed in a series of HIV-positive patients receiving modern radiation treatments, and compare patients receiving HIV protease inhibitors (PI) with patients not receiving HIV PIs. METHO...

Many studies have evaluated how the characteristics of feedback receiver, feedback deliverer and feedback information influence psychological feedback reactions of the feedback receiver while largely neglecting that feedback intervention is a kind of social interaction process. To address this issue, this study proposes that employees' perceived insider status (PIS), as a kind of employee-organ...

Pancreatic islets (PIs) transplantation is an alternative approach for the treatment of severe forms of type 1 diabetes (T1D). To monitor the success of transplantation, it is desirable to follow the location of engrafted PIs non-invasively. In vivo magnetic resonance imaging (MRI) of transplanted PIs is a feasible cell tracking method; however, this requires labeling with a suitable contrast a...

HIV protease inhibitors (HIV-PIs) target the HIV aspartyl protease, which cleaves the HIV gag-pol polyprotein into shorter proteins required for the production of new virions. HIV-PIs are a cornerstone of treatment for HIV but have been associated with lipodystrophy and other side effects. In both human and mouse fibroblasts, we show that HIV-PIs caused an accumulation of prelamin A. The prelam...

PURPOSE The aim of this study was to examine if package inserts (PIs) supplied with prescribed and over-the-counter medications in Saudi Arabia contain information relevant for the safe and appropriate use of these medications. METHODS Sixty PIs for prescription-only medications (n = 37) and over-the-counter medications (n = 23) were evaluated against a set of safety criteria compiled from th...

The goat polled intersex syndrome (PIS) is a full association between the absence of horns and intersexuality. Several pairs of primer were designed to detect the complete or partial deletion of 11.7 kb fragment in PIS goat. We proved that the 11.7 kb fragment was not deleted completely but partially in PIS goat. The special 198 base substitutions were found between normal and PIS dairy goats, ...
