Resumen
Burkholderia sensu lato is a large and complex group, containing pathogenic, phytopathogenic, symbiotic and non-symbiotic strains from a very wide range of environmental (soil, water, plants, fungi) and clinical (animal, human) habitats. Its taxonomy has been evaluated several times through the analysis of 16S rRNA sequences, concantenated 4–7 housekeeping gene sequences, and lately by genome sequences. Currently, the division of this group into Burkholderia, Caballeronia, Paraburkholderia, and Robbsia is strongly supported by genome analysis. These new genera broadly correspond to the various

Resumen
Cathode material Li[Ni1/3Co1/3Mn1/3]O2 for lithium-ion batteries with layered hexagonal structure was successfully synthesized in sol-gel way. The influences of calcination temperature (from 700° to 1000°C) on the structure and electrochemical behaviors of Li[Ni1/3Co1/3Mn1/3]O2 were extensively investigated. The results of XRD show that all samples are isostructural with α-NaFeO2 with a space group R-3m. XPS analysis shows that the oxidation states of Co and Mn were Co3+ and Mn4+ respectively, while Ni exists as Ni2+ and Ni3+. The charge-discharge experiments show that the sample calcined at 8

Extensive mutagenesis followed by in vivo expression analysis showed that three sequences of 4 bases each (−170 ACAA −167, −161 ACAA −158, and −145 TTGT −142) are required for maximal stimulation of in vivo transcription of the P1 promoter.

Activation of mitogen-activated protein kinase (MAP kinase) plays an important role in the cellular effects of nerve growth factor (NGF). Although the precise pathway by which NGF activates MAP kinase is not clear, several enzymes have been identified that may form a linear phosphorylation cascade, in which MAP kinase is activated by MAP kinase kinase (MEK). A key enzyme that links the ras-GTP complex to MEK is widely believed to be the raf kinase. However, immunoprecipitation experiments in PC-12 cells revealed that raf is not the major NGF-dependent MEK kinase [Zheng, Ohmichi, Saltiel and Gu

ABSTRACT Alterations of T-cell receptor signaling by human immunodeficiency virus type 1 (HIV-1) Nef involve its association with a highly active subpopulation of p21-activated kinase 2 (PAK2) within a dynamic signalosome assembled in detergent-insoluble membrane microdomains. Nef-PAK2 complexes contain the GTPases Rac and Cdc42 as well as a factor providing guanine nucleotide exchange factor (GEF) activity for Rac/Cdc42. However, the identity of this GEF has remained controversial. Previous studies suggested the association of Nef with at least three independent GEFs, Vav, DOCK2/ELMO1, and βP

Resumen
ABSTRACT Ras proteins can activate at least three classes of downstream target proteins: Raf kinases, phosphatidylinositol-3 phosphate (PI3) kinase, and Ral-specific guanine nucleotide exchange factors (Ral-GEFs). In NIH 3T3 cells, activated Ral-GEFs contribute to Ras-induced cell proliferation and oncogenic transformation by complementing the activities of Raf and PI3 kinases. In PC12 cells, activated Raf and PI3 kinases mediate Ras-induced cell cycle arrest and differentiation into a neuronal phenotype. Here, we show that in PC12 cells, Ral-GEF activity acts opposite to other Ras effectors.

The susceptibilities of 379 clinical mutans streptococcal isolates to chlorhexidine (CHX) were tested by agar dilution according to the standards of the National Committee for Clinical Laboratory Standards. Isolates were obtained from saliva samples of 34 young mothers who had high or moderate salivary levels of mutans streptococci at baseline. Samples were collected on three occasions, before childbirth, when each child was 6 months old, and 1 year later. Of these isolates, 50% were inhibited at 1 microgram of CHX per ml, 90% were inhibited at 2.0 micrograms/ml, and all were inhibited at 4.0

Resumen
ABSTRACT Neu differentiation factors (NDFs), or neuregulins, are epidermal growth factor-like growth factors which bind to two tyrosine kinase receptors, ErbB-3 and ErbB-4. The transcription of several genes is regulated by neuregulins, including genes encoding specific subunits of the acetylcholine receptor at the neuromuscular junction. Here, we have examined the promoter of the acetylcholine receptor ɛ subunit and delineated a minimal CA-rich sequence which mediates transcriptional activation by NDF (NDF-response element [NRE]). Using gel mobility shift analysis with an NRE oligonucleotide,

S100A6 jest białkiem wiążącym wapń, którego gen zidentyfikowano po raz pierwszy jako gen indukowany czynnikami wzrostu. Od tego czasu przyjmuje się, że S100A6 jest białkiem biorącym udział w proliferacji i pokrewnych procesach komórkowych. Podczas gdy struktura S100A6 i kinetyka wiązania Ca2+ zostały dość wcześnie określone to badania nad mechanizmem działania S100A6 są prowadzone stosunkowo od niedawna. Niemniej wydaje się oczywiste, że S100A6 pełni swoją funkcję w komórce poprzez oddziaływanie w wieloma ligandami, z których większość została zidentyfikowana w naszym zespole. Ostatnio nasze b

Resumen
An attempt has been made to synthesize nickel (up to 5 at%) containing ZnO diluted magnetic semiconductors by sol–gel process using zinc acetate dihydrate, nickel acetate tetrahydrate and oxalic acid as precursors and ethanol as solvent. The process comprises of gel formation, digestion at 80 °C for 24 h to obtain oxalate and calcination at 400 °C or above for 2 h for decomposition to oxide. The resulting powders correspond to wurtzite hexagonal structure similar to that of pure ZnO and contain nanoparticles of average diameter decreasing with (i) decrease of calcination temperature and (ii) r

Nuclear factor I (NFI) is a group of related site-specific DNA-binding proteins that function in adenovirus DNA replication and cellular RNA metabolism. We have measured both the levels and forms of NFI that interact with a well-characterized 26-base-pair NFI-binding site. Five different NFI-DNA complexes were seen in HeLa nuclear extracts by using a gel mobility shift (GMS) assay. In addition, at least six forms of NFI were shown to cross-link directly to DNA by using a UV cross-linking assay. The distinct GMS complexes detected were composed of different subspecies of NFI polypeptides as ass

Resumen
Die skryf van dié tipe artikel is altyd ’n gevaarlike onderneming: dit is onvermydelik voorskriftelik (en as sodanig druis dit in teen alles wat ek in verband met poësie geleer het), dis beperkend, patroniserend, laat nie genoeg speelruimte vir die individuele talent nie, en is ook noodgedwonge vereenvoudigend van iets so kompleks soos die skryf van ’n gedig. Daar is geen reëls in die poësie nie. Wys my 'n reël en ek wys jou ’n gedig wat dit skitterend oortree. Ek storm nietemin in waar engele huiwer om voet neer te sit, want ek glo dat niks op aarde werklike talent kan onderkry nie.

Raakpunte in die studie van Latyn en Hebreeus kom nie dikwels tot hulle reg in die akademiese wêreld nie, en Suid-Afrika is seker geen uitsondering op die reël nie. Tog is daar 'n groot terrein wat op ontginning wag in hierdie verband. As blyk van waardering word hierdie poging in die rigting aangebied aan 'n geëerde leermeester op wie se rekening die gebreke nie geplaas moet word nie. Die Latynse vertalings van die Ou Testament waaraan aandag gegee word, is die Vetus Latina (VL) en die Vulgaat (V). Hulle word vergelyk met die Massoretiese teks (MT), die standaard Hebreeuse teks van die Ou Tes

Resumen
Die doel met die ondersoek was om die verband tussen verbale/nie-verbale intelligensieverskille op die Nuwe Suid-Afrikaanse Groeptoets (NSAG) en persoonlikheidsfunksionering van adolessente te ondersoek. Die ondersoekgroep het uit matriekleerlinge bestaan. Hulle is volgens IK-tellings onderverdeel in drie groepe: een groep by wie die nie-verbale telling die verbale telling met 15 punte oorskry, 'n tweede groep by wie die verbale telling die nie-verbale telling met dieselfde aantal punte oorskry en 'n derde groep by wie die verbale en nie-verbale tellings met nie meer as vyf punte verskil nie.
