Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3). The steric hindrance of the equatorial OH group probably prevents the trans isomer from entering into such reaction. Triol (3) was also obtained from the reduction of the d...

For those who do not consume preformed DHA from dietary sources, concern has been expressed about the potential inhibitory effect of high trans fatty acid (TFA) intakes in the diet relative to ALA and the potential for an even more compromised conversion efficiency from ALA to DHA. This concern is based on extensive literature indicating that high trans intakes in experimental animals partially...

The asymmetric unit of the title compound, [Co(C(8)H(6)NO(2))(2)(H(2)O)(4)], contains one half-mol-ecule. The Co(II) atom lies on an inversion centre and is coordinated by two N atoms of the pyridine rings of 3-(3-pyrid-yl)acrylate anions and four O atoms of water mol-ecules in a distorted octa-hedral coordination geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the...

A new antimicrobial nitrofuran designated SQ 18,506 showed some therapeutic activity when administered orally to mice infected with Escherichia coli, Salmonella schottmuelleri, Shigella flexneri, or Klebsiella pneumoniae. Animals infected parenterally with Streptococcus pyogenes, Proteus mirabilis, Mycobacterium tuberculosis, and Candida albicans, or topically with Trichophyton mentagrophytes, ...

A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...
