    Optical Characterization of Different Thin Film Module Technologies (2015)
    Hindawi
    Details
    Publication Date: 2015-06-09
    Description: For a complete quality control of different thin film module technologies (a-Si, CdTe, and CIS) a combination of fast and nondestructive methods was investigated. Camera-based measurements, such as electroluminescence (EL), photoluminescence (PL), and infrared (IR) technologies, offer excellent possibilities for determining production failures or defects in solar modules which cannot be detected by means of standard power measurements. These types of optical measurement provide high resolution images with a two-dimensional distribution of the characteristic features of PV modules. This paper focuses on quality control and characterization using EL, PL, and IR imaging with conventional cameras and an alternative excitation source for the PL-setup.

    The receptor for the cytotoxic ligand TRAIL (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-04-04
    Description: TRAIL (also known as Apo-2L) is a member of the tumor necrosis factor (TNF) ligand family that rapidly induces apoptosis in a variety of transformed cell lines. The human receptor for TRAIL was found to be an undescribed member of the TNF-receptor family (designated death receptor-4, DR4) that contains a cytoplasmic "death domain" capable of engaging the cell suicide apparatus but not the nuclear factor kappa B pathway in the system studied. Unlike Fas, TNFR-1, and DR3, DR4 could not use FADD to transmit the death signal, suggesting the use of distinct proximal signaling machinery. Thus, the DR4-TRAIL axis defines another receptor-ligand pair involved in regulating cell suicide and tissue homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, G -- O'Rourke, K -- Chinnaiyan, A M -- Gentz, R -- Ebner, R -- Ni, J -- Dixit, V M -- DAMD17-96-1-6085/DA/NIDA NIH HHS/ -- ES08111/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1997 Apr 4;276(5309):111-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Michigan Medical School, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9082980" target="_blank"〉PubMed〈/a〉

    Determination of type I receptor specificity by the type II receptors for TGF-beta or activin (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-11-05
    Description: Transforming growth factor-beta (TGF-beta) and activin signal primarily through interaction with type I and type II receptors, which are transmembrane serine-threonine kinases. Tsk 7L is a type I receptor for TGF-beta and requires coexpression of the type II TGF-beta receptor for ligand binding. Tsk 7L also specifically bound activin, when coexpressed with the type IIA activin receptor. Tsk 7L could associate with either type II receptor and the ligand binding specificity of Tsk 7L was conferred by the type II receptor. Tsk 7L can therefore act as type I receptor for both activin and TGF-beta, and possibly other ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebner, R -- Chen, R H -- Lawler, S -- Zioncheck, T -- Derynck, R -- New York, N.Y. -- Science. 1993 Nov 5;262(5135):900-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Growth and Development, and Anatomy, University of California at San Francisco 94143-0640.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8235612" target="_blank"〉PubMed〈/a〉

    Cloning of a type I TGF-beta receptor and its effect on TGF-beta binding to the type II receptor (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-28
    Description: Transforming growth factor-beta (TGF-beta) affects cellular proliferation, differentiation, and interaction with the extracellular matrix primarily through interaction with the type I and type II TGF-beta receptors. The type II receptors for TGF-beta and activin contain putative serine-threonine kinase domains. A murine serine-threonine kinase receptor, Tsk 7L, was cloned that shared a conserved extracellular domain with the type II TGF-beta receptor. Overexpression of Tsk 7L alone did not increase cell surface binding of TGF-beta, but coexpression with the type II TGF-beta receptor caused TGF-beta to bind to Tsk 7L, which had the size of the type I TGF-beta receptor. Overexpression of Tsk 7L inhibited binding of TGF-beta to the type II receptor in a dominant negative fashion. Combinatorial interactions and stoichiometric ratios between the type I and II receptors may therefore determine the extent of TGF-beta binding and the resulting biological activities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebner, R -- Chen, R H -- Shum, L -- Lawler, S -- Zioncheck, T F -- Lee, A -- Lopez, A R -- Derynck, R -- New York, N.Y. -- Science. 1993 May 28;260(5112):1344-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Growth and Development, University of California, San Francisco 94143-0640.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8388127" target="_blank"〉PubMed〈/a〉

    Inactivation of the type II receptor reveals two receptor pathways for the diverse TGF-beta activities (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-28
    Description: Transforming growth factor-beta (TGF-beta) is a multifunctional protein that regulates cell proliferation and differentiation and extracellular matrix production. Although two receptor types, the type I and type II receptors, have been implicated in TGF-beta-induced signaling, it is unclear how the many activities of TGF-beta are mediated through these receptors. With the use of cells overexpressing truncated type II receptors as dominant negative mutants to selectively block type II receptor signaling, the existence of two receptor pathways was shown. The type II receptors, possibly in conjunction with type I receptors, mediate the induction of growth inhibition and hypophosphorylation of the retinoblastoma gene product pRB. The type I receptors are responsible for effects on extracellular matrix, such as the induction of fibronectin and plasminogen activator inhibitor I, and for increased JunB expression. Selective inactivation of the type II receptors alters the TGF-beta response in a similar manner to the functional inactivation of pRB, suggesting a role for pRB in the type II, but not the type I, receptor pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, R H -- Ebner, R -- Derynck, R -- New York, N.Y. -- Science. 1993 May 28;260(5112):1335-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Growth and Development, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8388126" target="_blank"〉PubMed〈/a〉

    Notes: The scr genes located on plasmid pUR400 and responsible for sAucrose (Scr) metabolism of Escherichia coli K12 and other enteric bacteria have been cloned on a 9.3 kb DNA fragment. The different genes were mapped by transposon insertion mutagenesis, by restriction endonuclease and deletion mapping, and the corresponding gene products were identified. Besides the known structural genes scrA, coding for an EnzymellScr (45 kD) of the phosphoenolypyruvate-dependent phosphotransferase system (PTS), and scrB, coding for a sucrose 6-phosphate hydrolase (invertase) (55 kD), two new structural genes were discovered. Gene scrK apparently codes for an intracellular and ATP-dependent fructokinase (39 kD), while scry seems to code for a sucrose porin (58 kD) in the outer cell membrane. No genes for an Enzyme IIIScr of the PTS or for (a) glycosyltransferase(s) were detected. The four genes form an scr operon (gene order, scrK scrY scrA scrB, transcription from K to B), regulated by a repressor (gene scrR, 37 kD) and inducible by sucrose, fructose and fructose-containing oligosaccharides

    DNA sequence of the gene scrA encoding the sucrose transport protein EnzymellScr of the phosphotransferase system from enteric bacteria: homology of the EnzymellScr and EnzymellBgl proteins (1988)

    Notes: The nucleotide sequence of the structural gene, scrA, which codes for sucrose-specific EnzymellScr (EIIScr) of the phosphoenolpyruvate-dependent carbohydrate: phosphotransferase system (PTS), was determined. EllScr requires an Enzymelll, the product of the gene crr, for full activity. The gene scrA is preceded immediately by a classical Shine-Dalgarno sequence (AAGAGGGTA). It contains 1368 nucleotides with an increased GC-content (58%) corresponding to a polypeptide of 455 amino acid residues (Mr 47 500). The protein has the hydropathic profile (average hydropathy +0.82) of an integral membrane protein lacking extended α-helical structures and a signal peptide. Comparison with the sequence of the β-glucoside-specific Enzymell (EllBgl, 625 amino acids, Mr 66480; Bramley and Kornberg, 1987a; Schnetz et al., 1987) revealed strong homologies between EllScr and the first 458 residues of EllBgl. The 162 carboxyterminal residues of EllBgl, however, showed a high homology with the sequence of Enzymelll (Nelson et al., 1984), a homology also described recently by Bramley and Kornberg (1987b). The evolutionary and functional significance of the similarities with four other Enzymesll is discussed.

    A sugar-specific porin, ScrY, is involved in sucrose uptake in enteric bacteria (1991)

    Notes: During the molecular analysis of a plasmid-coded sucrose metabolic pathway of enteric bacteria, a gene, scrY, was found whose product, ScrY, had all the properties of a bacterial porin (Schmid et al, 1988). Loss of this protein (Mr 58kDa), localized in the outer membrane, led, as shown here, to an increase in the apparent Km for sucrose transport in whole cells from 10 μM in wild-type cells to 300 μM in mutant cells. This contrasts with the Km for sucrose phosphorylation as measured in membrane vesicles from mutant and wild-type cells, which remained unchanged at about 10 μM, and reflects the activity of the sucrose-specific Enzymell of the phosphoenolpyruvate-dependent carbohydrate:phosphotransferase system (PTS) responsible for uptake through the inner membrane. Furthermore, the presence of ScrY restored growth on maltodextrins in cells devoid of LamB, thus complementing the lack of this maltoporin. The amino acid sequence deduced from the DNA sequence was determined for the plasmid-coded and the ScrY porin coded in the chromosome of Klebsiella pneumoniae. Both show high identity (86%) to each other, and to the channel domain of LamB, further corroborating the conclusion that they constitute porins.
