O30-4 Occupational noise exposure during pregnancy and preeclampsia

Oral Session 30 – Reproductive 2, 2016
Background Women of childbearing age are in many parts of the world occupationally active. This leads to a large number of pregnancies potentially exposed to occupational exposures. Occupational and residential noise has been identified as a risk factor for cardiovascular disease in adults.

195Pt NMR of Pt309Phen 36 * O30 Metallic Clusters

1992
195Pt NMR lineshape and spin-lattice relaxation measurements at 77 K are presented for the polynuclear metallic cluster compound Pt309Phen 36 * O30 Two peaks in the NMR lineshape are found centered at Ho/v0=1.110 G/kHz and 1.096 G/kHz. The high field peak is attributed to Pt spins located in the interior of the cluster which are in a metallic ...

O30: Comparing the performance of HR-TOFMS and immunoassay for urine drug screening

Toxicologie Analytique et Clinique, 2014
Introduction Immunoassay screening tests are widely used in clinical and forensic toxicology. However, the emergence of new psychoactive substances (NPS) has challenged the scope and sensitivity of these methods. Consequently, specialized analytical toxicology laboratories are today relying more and more on mass spectrometry based techniques.

O30 Treatment failure in mycoplasma genitalium among gum clinic attendees

Sexually Transmitted Infections, 2017
IntroductionMacrolide resistance inMycoplasma genitalium(MG) is of growing concern in countries where azithromycin is used to treat non-gonococcal urethritis(NGU) but UK data is lacking. Patients with NGU or pelvic inflammatory disease (PID) are routinely tested for MG at our clinic and offered test of cure (TOC) 4 weeks post-treatment.

Ferroelectric and Ferrimagnetic Properties of (Ba6−2xR2x) (Nb9−xFe1+x)O30

Journal of Applied Physics, 1960
Materials which possess properties, which strongly suggest both ferroelectricity and ferrimagnetism, are found in the systems (Ba6−2xR2x) (Nb9−xFe1+x)O30 where R is a trivalent rare earth ion and x can vary from 0 to 1. X-ray diffraction powder patterns indicate a single phase having the potassium tungsten bronze type structure also exhibited by ...

[Structure of the O-specific polysaccharide from Proteus mirabilis O30].

Biokhimiia (Moscow, Russia), 1996
Based on acid hydrolysis, methylation, and one- and two-dimensional 1H- and 13C-NMR spectroscopy, including homonuclear and 1H, 13C heteronuclear correlation spectroscopy (COSY) and rotating-frame nuclear Overhauser effect spectroscopy (ROESY); it was found that the O-specific polysaccharide chain of the lipopolysaccharide of the bacterium Proteus ...

O30 The use of a multi locus sequence typing scheme to characterize Canadian isolates of Corynebacterium diphtheriae

International Journal of Antimicrobial Agents, 2009
Objective: The tcdC gene of C. difficile negatively regulates the production of toxins A and B. Mutations within this gene may result in loss of the negative regulatory role, potentially leading to hyperproduction of toxins and increased virulence. This hypervirulent strain caused an epidemic of C. difficile-associated disease in Quebec in 2002 and has

O30. Diet and preeclampsia: A prospective multicentre unmatched case control study in Ethiopia

Pregnancy Hypertension: An International Journal of Women's Cardiovascular Health, 2015
Background Preeclampsia is one of the most commonly encountered hypertensive disorders of pregnancy that accounts for 20–80% of maternal mortality in developing countries, including Ethiopia. For many years diet have been suggested to play a role in preeclampsia.
