Spectral computed tomography (CT) has become increasingly of interest with the development of photon counting X-ray detector technology. The energy selective measurement capabilities of these devices open the doors to many exciting directions in CT research across a number of fields including security applications. Over the past year our work under ALERT support has been directed at the continu...

30 and 50S ribosomal subunits, released from polysomes upon polypeptide chain termination, possess a high affinity for each other and readily form single ribosomes. Highly purified initiation factor F3(B), acting stoichiometrically, prevents the formation of single ribosomes without promoting their dissociation. These findings are interpreted in terms of a ribosome cycle in which a limiting amo...

Purple corn is a cereal plant that has health benefits. contains anthocyanins, which are useful as anticancer and antioxidants, high nutritional value. Improving the quality of production can be done through breeding. This study aimed to determine value variability, heritability expected genetic advance F3 purple from open-pollinated hybridization. The research was conducted December 2020 April...

Abstract Flavonoids, such as anthocyanins, proanthocyanidins, and flavonols, are widespread plant secondary metabolites important for adaptation to diverse abiotic biotic stresses. Flavonoids can be variously hydroxylated decorated; their biological activity is partly dependent on the degree of hydroxylation B-ring. Flavonoid biosynthesis regulated by MYB transcription factors, which have been ...

Daun sirsak (Annona muricata L.) mengandung flavonoid yang memiliki aktivitas antioksidan sangat kuat . Telah dibuat formula handbody lotion daun masing-masing 0,05% (F1), 0,1% (F2), 0,15% (F3). Tujuan penelitian ini untuk melihat dari ketiga ekstrak etanol (F1, F2, F3) telah dibuat.Uji dilakukan terhadap F1, dan F3 menggunakan metode DPPH dengan menentukan nilai IC 50 formula. Hasil menunjukka...

Mcl-1 is a member of the Bcl-2 family protein; its degradation is required for the initiation of apoptosis. The mechanism, however, is not yet clearly known. Previously, it was reported that Mcl-1 is degraded through the ubiquitination-mediated pathway and the PEST domain is the motif responsible for promoting this degradation. We found evidence that this may not be true. We generated several M...

Melastoma malabathricum Linn. is a perennial traditional medicine plants that grows abundantly throughout Asian countries. In this study, M. malabathricum Linn. leaf hot water crude extract with anticoagulant activity was purified through solid phase extraction cartridge and examined for the bioactive chemical constituents on blood coagulation reaction. The SPE purified fractions were, respecti...

BACKGROUND Epidemiology studies have linked exposure to pollutant particles to increased cardiovascular mortality and morbidity, but the mechanisms remain unknown. OBJECTIVES We tested the hypothesis that the ultrafine fraction of ambient pollutant particles would cause endothelial cell dysfunction. METHODS We profiled gene expression of human pulmonary artery endothelial cells (HPAEC) expo...
