The films have been prepared by spincoating a mixture of PVA, ammonium dichromate and metal (zinc or silver) precursor from water solutions, and then rendered insoluble by crosslinking under UV illumination. Antimicrobial activity has been tested against different bacteria and fungi, such as Bacillus atrophaeus, Bacillus megaterium, Staphylococcus aureus, Enterococcus faecium, Pseudomonas

aeruginosa, Salmonella enterica, Escherichia coli, Neurospora crassa, and Saccharomyces cerevisiae. It was found that combining the zinc and silver precursors resulted in films which had excellent antimicrobial activity and at the same time exhibited superior environmental stability compared to films containing prepared with single Daporinad purchase metal precursor.

“Fetal warfarin syndrome (warfarin embryopathy) is a consequence of maternal ingestion of warfarin during pregnancy. Warfarin fetotoxicity comprises wide range of manifestations including dysmorphology in neonate with characteristic classical features of nasal hypoplasia and stippling of epiphyses.

Here we present a case of a neonate whose mother was on unsupervised warfarin prophylaxis throughout pregnancy. A brief review of literature with suitable options

for anticoagulation during pregnancy is discussed.

The final consensus over LMWH and warfarin in the first trimester is yet to be finalised. The treatment of warfarin embryopathy is

symptomatic. Long term sequels in survivors are still not known.”
“The parameters for reducing the threshold current density of InAs/InGaAsP/InP quantum- dot (QD) lasers suitable for high temperature operation are studied. The structures were grown using metalorganic vapor phase epitaxy. Increasing the number of QD layers leads to a substantial improvement of the optical confinement and a markedly reduced threshold per dot layer in broad area devices. A reduction of the spacer thickness between the QD layers was not found to significantly affect device characteristics. Depending upon the device length, an optimum number of QD layers was deduced. Based C59 Wnt inhibitor upon optimized QD stacks, buried- heterostructure lasers with a medium device length emitting at 1.5 mu m were fabricated. Laterally single- mode devices show promising low threshold currents near 10 mA and good thermal stability with a characteristic temperature of 65 K up to 90 degrees C.

“Electrochemical polymerization of aniline on nanostructured Ni substrates was investigated. To this aim, the Ni substrate electrodes were prepared by casting various samples of Ni nanoparticles having different morphologies.
