Distribution of colored carotenoids between light-harvesting complexes in the process of recovering carotenoid biosynthesis in Ectothiorhodospira haloalkaliphila cells.
Pushchino, Russia. In J Photochem Photobiol B, 16 Oct 2014
It has been found that (1) the rate of recovering colored-Car biosynthesis in the lag-phase is far ahead of the growth rate of the cells themselves; (2) several Cars (ζ-carotene, neurosporene etc.) act as intermediates in Car biosynthesis; (3) because filling the "empty" Car pockets in the LH1-RC complexes is faster than in LH2, available spirilloxanthin is preferentially incorporated into the nascent LH1-RC core particles; (4) as a consequence of the resulting lack of spirilloxanthin availability, the biosynthetic intermediates (anhydrorhodovibrin, rhodopin and lycopene) fill the empty nascent LH2 Car pockets.
Reproduction, smell, and neurodevelopmental disorders: genetic defects in different hypogonadotropic hypogonadal syndromes.
Liège, Belgium. In Front Endocrinol (lausanne), Dec 2013
Interestingly, defects in PROKR2, FGFR1, FGF8, CHD7, DUSP6, and WDR11 genes are also associated with normosmic IHH, whereas mutations in KISS1/KISSR, TAC3/TACR3, GNRH1/GNRHR, LEP/LEPR, HESX1, FSHB, and LHB are only present in patients with normosmic IHH.
Bone collagen: new clues to its mineralization mechanism from recessive osteogenesis imperfecta.
Seattle, United States. In Calcif Tissue Int, Oct 2013
They include CRTAP, LEPRE1, and PPIB, which encode three proteins forming the prolyl 3-hydroxylase complex; PLOD2 and FKBP10, which encode, respectively, lysyl hydroxylase 2 and a foldase required for its activity in forming mature cross-links in bone collagen; SERPINH1, which encodes the collagen chaperone HSP47; SERPINF1, which encodes pigment epithelium-derived factor required for osteoid mineralization; and BMP1, which encodes the type I procollagen C-propeptidase.
The medial habenula: still neglected.
Houston, United States. In Front Hum Neurosci, 2012
While the lateral habenula (LHb) has been extensively studied, the anatomically and histochemically distinct medial habenula (MHb) remains largely understudied.
Structural and functional proteomics of intracytoplasmic membrane assembly in Rhodobacter sphaeroides.
United States. In J Mol Microbiol Biotechnol, 2012
Functional aspects of the photosynthetic unit assembly process were monitored by fluorescence induction/relaxation measurements of the variable fluorescence arising from LH-bacteriochlorophyll a. Slowing of the rate of RC electron transfer turnover (τQA), as assessed from the relaxation phase, was correlated with the growth of the functional absorption cross section (σ) and LH2/LH1 molar ratios.
Luteinizing hormone beta mutation and hypogonadism in men and women.
Brasília, Brazil. In N Engl J Med, 2007
homozygous mutation of a 5' splice site in LHB: IVS2+1G-->C disrupts the splicing of messenger RNA, generating a gross abnormality in the processing of the luteinizing hormone beta-subunit mRNA, which abrogates the secretion of luteinizing hormone
