The purpose of this study was to examine the physicochemical properties of TA ointments and conduct a human sensory test to assess the properties of those ointments. Physicochemical assessment was done via near-infrared (NIR) absorption spectroscopy, measurement of water content, microscopy, and measurement of viscoelasticity. The human sensory test examined 5 aspects (texture, cohesiveness, sp...

It is argued that reliable acoustic profiles of speech under stress can only be found if different types of stress are clearly distinguished and experimentally induced. We report first results of a study with 100 speakers from three language groups, using a computer-based induction procedure that allows distinguishing cognitive load due to task engagement from psychological stress. Findings sho...

The activity of the atrial natriuretic peptide receptor (Npr1) is altered in spontaneously hypertensive rats (SHR) in relation to its mRNA levels, suggesting abnormal transcriptional control in hypertension. A single-stranded conformational polymorphism caused by a repetitive dinucleotide segment of 10 TA in BN-Lx and of 40 TA in SHR was localized at position -943 relative to the transcription ...

Thioacetamide (TA), a potent centrilobular hepatotoxicant, undergoes a two-step bioactivation mediated by microsomal CYP2E1 to TA sulfoxide (TASO), and further to TA-S,S-dioxide (TASO2), a reactive metabolite that initiates cellular necrosis. Our earlier studies showed that bioactivation-mediated liver injury of TA is not dose-proportional. The objective of this study was to examine whether inc...

There is increasing evidence that androgens play a significant role in the development and progression of breast cancer. 5alpha-Reductase (SRD5A2) is an enzyme that is expressed in androgen-dependent tissues, and it catalyzes the reduction of testosterone to its more bioactive form, dihydrotestosterone, which then transactivates a number of genes. One of these genes encodes for prostate-specifi...

In the present study, the bovine coronavirus (BCV) spike glycoprotein cleavage products (S1 and S2) were individually expressed in Spodoptera frugiperda (Sf9) insect cells, using a baculovirus expression system. The coding sequence of S1 and S2 gene fragments were amplified by RT-PCR and cloned into the baculovirus shuttle vector pBlueBac4.5/V5-His TOPO ® TA. The cloned fragments were inserted ...

Human JL-calpain is activated maximally by 100-200 JLM Ca2+. Both the 80 kDa and 29 kDa subunits of JL-calpain have a EF-hand type calcium-binding domain. It is known that trivalent terbium ion (Tb3+) mimics Ca2+ in many biological systems. We found that Tb3+ alone transiently activated calpain. However, in the presence of Ca2+ , Tb3+ inhibited JL-calpain with an IC5o of about loo JLM. As high ...

Several transfer RNA precursors which accumulate in a strain of Escherichia coli temperature-sensitive for RNase P have been described. These precursors range from 135 to 690 nucleotides in length. Their tRNA content has been determined by digestion of the precursors to 4 S RNA, followed by Sanger fingerprint analysis of the purified 4 S material. Identification of some of these tRNAs, as well ...
