Regulation and Expression of ELOVL Fatty Acid Elongase-5 Genes with Overfeeding in Goose Fatty Liver
Goose liver was an important economic trait which can be affected by high carbohydrate diet contents. So, fatty acid elongase ELOVL plays an important role in the synthesis of long-chain polyunsaturated fatty acids (LCPUFA). We hypothesized that ELOVL5 are involved in goose fatty liver development. To address this, we determined the response of goose ELOVL5 gene to overfeeding and their expression in goose liver and primary hepatocytes with related factors (glucose, fatty acid and insulin). Overfeeding expression data indicated that ELOVL5 was significantly reduction after two days of overfed. In primary hepatocytes data expression by quantities PCR was not affected by glucose and palmitate treatment while reduction expression by high level of insulin. Bioinformatics analysis of the sequence gene was indicated considerably conserved among avian species.

Hydrophobicity properties of graphite and reduced graphene oxide of the polysulfone (PSf) mixed matrix membrane
Hydrophobicity properties of graphite and reduced graphene oxide (rGO) (from exfoliated graphite/rGO) towards PSf polymer membrane characteristic and properties at different additives weight concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. Both PSF/graphite and PSf/rGO membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed that membrane with graphite and reduced graphene oxide nearly diminished their O-H bonding which was opposite to the graphene oxide peak that shows a strong O-H bonding as increased exfoliated times. These results were in line with the contact angle results that showed strong hydrophobicity of graphite and reduced graphene oxide membranes as increased these additives concentration. The effect of strong hydrophobicity in these membranes also has resulted in smoother surface roughness compared to pristine PSf membrane. Further investigation of the performance of water flux also proved that both above membranes have strong hydrophobic effect, with the lowest pure water flux rate (L/m2h) was given by PSf/rGO 3% membrane at 19.2437 L/m2h
The Impact Of Learning Style And Self – Efficacy On Academic Performance Of Mba Candidates
The demand for the MBA program is considered high in Malaysia and to select the suitable MBA candidate that can excel in his performance encouraged me to do this research. The MBA program is different from other postgraduate program in the sense that it’s candidates merge from different backgrounds with different learning styles and this might make them differ in their academic performance
An improved Agrobacterium mediated transformation in tomato using hygromycin as a selective agent
Bacterial wilt is a devastating disease of tomato crop throughout the world. This disease is very dangerous in hot and humid regions, where it spreads with the irrigation water to whole field within days, which resulted in severe decline in yield. Two varieties of tomato were used for developingbacterial wilt resistance. Riogrande responded more efficiently as compared to Roma. Regeneration frequency of 90.6% was achieved when leaf discs were used and 82.5% when hypocotyls were used as explant for tomato cv. Riogrande. While 65.4% regeneration was achieved from hypocotyls and 72.6% regeneration was obtained when leaf discs were used as explant for cv. Roma. Explants were cocultivated with Agrobacterium strain EHA101 containing a binary vector pTCL5, having hygromycin phosphotransferase (HPT) gene which confers resistance to hygromycin and -glucuronidase (GUS) gene in addition to Xa21 gene. Hygromycin (25 mg/l) was used as selectable marker while GUS is areporter gene. Acetosyringone (50 mM) enhanced transformation effeciency. Preselection period of 7 days was found to be indispensable for successful transformation of tomato crop. Transformation efficiency of 24% was observed for Riogrande and 8% for Roma. Molecular analysis of transgenic plants produced was carried out for hygromycin resistance gene. Transgenic plants contained the expected band of 670 bp. PCR analysis confirmed the foreign DNA in to the plant genome
Some inequalities for the Euclidean operator radius of two operators in Hilbert -Modules space
The Euclidean operator radius of two bounded linear operators in the Hilbert
-module over \A is given some precise bounds. Their relationship to
recent findings in the literature that offer precise upper and lower bounds on
the numerical radius of linear operators is also established.Comment: 12 page
Testing collapse models with levitated nanoparticles: the detection challenge
We consider a nanoparticle levitated in a Paul trap in ultrahigh cryogenic
vacuum, and look for the conditions which allow for a stringent
noninterferometric test of spontaneous collapse models. In particular we
compare different possible techniques to detect the particle motion. Key
conditions which need to be achieved are extremely low residual pressure and
the ability to detect the particle at ultralow power. We compare three
different detection approaches based respectively on a optical cavity, optical
tweezer and a electrical readout, and for each one we assess advantages,
drawbacks and technical challenges
Evaluation of noninvasive cardiac output methods during exercise
Noninvasive techniques to estimate cardiac output (Qc) will be used during future space flight. This retrospective literature survey compared the Qc techniques of carbon dioxide rebreathing (CO2-R), CO2 single breath (CO2-S), Doppler (DOP), impedance (IM), and inert gas (IG: acetylene or nitrous oxide) to direct (DIR) assessments measured at rest and during exercise
