The free chromophores (chr) extracted from macromomycin (MCR) and auromomycin (AUR) showed different IR spectra in KBr tablets and different CD spectra in ethanol or methanol solution. Chr-MCR contained a greater amount of alkyl moieties than chr-AUR as shown by much stronger IR absorbance at 2960 cm-1. The IR spectra of MCR, AUR and their apo-proteins (apo) in D2O showed that major parts of th...

The aim of the study was to explore the genetic architecture influencing weight of fast- and slow-twitch skeletal muscles. The weights of the slow-twitch soleus, the mixed gastrocnemius, the fast-twitch tibialis anterior (TA), and extensor digitorum longus (EDL) muscles were 11-34% greater (P < 0.001) in 200-day-old C57BL/6J (B6) than in DBA/2J (D2) mice. Male muscles were 13-28% larger than fe...

The cdc25C , cdc2 and cyclin A promoters are controlled by transcriptional repression through two contiguous protein binding sites, termed the CDE and CHR. In the present study we have identified a factor, CDF-1, which interacts with the cdc25C CDE-CHR module. CDF-1 binds to the CDE in the major groove and to the CHR in the minor grove in a cooperative fashion in vitro , in a manner similar to ...

Genetic and physical framework mapping in cotton (Gossypium spp.) were used to discover putative gene sequences involved in resistance to common soil-borne pathogens. Chromosome (Chr) 11 and its homoeologous Chr 21 of Upland cotton (G. hirsutum) are foci for discovery of resistance (R) or pathogen-induced R (PR) genes underlying QTLs involved in response to root-knot nematode (Meloidogyne incog...

We introduce a systematic, concurrent execution scheme for Constraint Handling Rules (CHR) based on a previously proposed sequential goal-based CHR semantics. We establish strong correspondence results to the abstract CHR semantics, thus guaranteeing that any answer in the concurrent, goal-based CHR semantics is reproducible in the abstract CHR semantics. Our work provides the foundation to obt...

Catharanthus roseus L. is a medicinal plant that produces numerous indole terpenoid alkaloids, including vincristine and vinblastine, which are used for cancer treatment. The effect of specified precursors (L-phenylalanine, L-tyrosine) elicitors (chitosan, methyl jasmonate) on C. hairy roots (CHR) growth has been examined in order to increase the content vinblastine. Our results showed CHR gene...

Bu çalışmada 5,7-dihidroksiflavon (chrysin, chr) ve 4,4′-di-ter-bütil-2,2′-bipiridin (4,4’-dtbbpy) ligandları kullanılarak Cu(II) iyonunun yeni bir karışık ligand-bakır(II) koordinasyon bileşiği elde edildi. Sentezlenen bu bileşiğinin yapısı, elementel analiz, iletkenlik, manyetik süsseptibilite, kütle spektrometrisi Infrared (IR) spektroskopisi yöntemleriyle aydınlatıldı. Ayrıca TGA/DSC analiz...

Constraint Handling Rules (CHR) are our proposal to allow more exibility and application-oriented customization of constraint systems. CHR are a declarative language extension especially designed for writing user-deened constraints. CHR are essentially a committed-choice language consisting of multi-headed guarded rules that rewrite constraints into simpler ones until they are solved. In this b...
