Trehalose and trehalose metabolism are crucial for insect development. We measured the content of polyhydric compounds in the hemolymph of diapause- and nondiapause-destined individuals of Helicoverpa armigera. We found that the trehalose content is much higher in diapause-destined individuals than that in nondiapause individuals. The activity of trehalose-6-phosphate synthase (TPS) during H. a...

Soybean lecithin transphosphatidylated phosphatidylserine (SB-tPS) is already known to improve the learning ability of aged or drug-induced amnesic rodents. In this study, its effect on normal adult rodents was evaluated using several learning tasks. Firstly, three behavioral tests (open-field, Y-maze, and active avoidance test) were consecutively carried out after the daily oral administration...

introduction dosimetric accuracy is a major issue in the quality assurance (qa) program for treatment planning systems (tps). an important contribution to this process has been a proper dosimetry method to guarantee the accuracy of delivered dose to the tumor. in brachytherapy (bt) of gynecological (gyn) cancer it is usual to insert a combination of tandem and ovoid applicators with a complicat...

Baseline design of the Taiwan photon Source (TPS) control system of NSRRC is proposed. The control system design is based on EPICS toolkits. Guidelines for hardware platform and operating system choice will be addressed. The EPICS test bed will be setup to evaluate various selected hardware and software components. The TPS control system will provide versatile environments for machine commissio...

Background: HDR brachytherapy is one of the commonest methods of nasopharyngeal cancer treatment. In this method, depending on how advanced one tumor is, 2 to 6 Gy dose as intracavitary brachytherapy is prescribed. Due to high dose rate and tumor location, accuracy evaluation of treatment planning system (TPS) is particularly important. Common methods used in TPS dosimetry are based on computat...

Secondary phenolic metabolites play an important role in plant defense mechanisms, and increasing evidence indicates that many are important in human health. To date, few studies have investigated the impact of various agricultural practices on levels of secondary plant metabolites. To address this issue, the total phenolic (TP) content of marionberries, strawberries, and corn grown by sustaina...

The thermomechanical behavior of damaged space shuttle tile thermal protection system is determined using the finite element method. The relative effects of damage on the thermal protection capability and the induced thermal stresses in the TPS are determined by comparing the thermal and structural response of the damaged configurations with the undamaged configurations. The TPS, consisting of ...

Experiments are conducted on damaged and undamaged space shuttle tile thermal protection system (TPS) to determine its thermomechnical behavior. The TPS specimens, which consists of a LI-900 tile, the strain isolator pad and the underlying structure, is subjected to a temperature profile corresponding to the thermal loading of the Access to Space (ATS) reference vehicle. Experiments are conduct...

The main purpose of urine cytology is to detect high-grade urothelial carcinoma. With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of high-grade urothe...

Sesterterpenoids are a rare terpene class harboring untapped chemodiversity and bioactivities. Their structural diversity originates primarily from the scaffold-generating sesterterpene synthases (STSs). In fungi, all six known STSs are bifunctional, containing C-terminal trans-prenyltransferase (PT) and N-terminal terpene synthase (TPS) domains. In plants, two colocalized PT and TPS gene pairs...
