BACKGROUND: Nausea and vomiting in pregnancy (NVP) affects up to 85% of all women during pregnancy, but for the majority self-management suffices. For the remainder, symptoms are more severe and the most severe form of NVP - hyperemesis gravidarum (HG) - affects 0.3-1.0% of pregnant women. There is no widely accepted point at which NVP becomes HG. OBJECTIVES: This study aimed to determine the relative clinical effectiveness and cost-effectiveness of treatments for NVP and HG...

Methylmalonyl-coA epimerase (MCE) follows propionyl-coA carboxylase and precedes methylmalonyl-coA mutase in the pathway converting propionyl-coA to succinyl-coA. MCE deficiency has previously been described in six patients, one presenting with metabolic acidosis, the others with nonspecific neurological symptoms or asymptomatic. The clinical significance and biochemical characteristics of this rare condition have been incompletely defined. We now describe a patient who presented acutely at 5 years of age with vomiting, dehydration, confusion, severe metabolic acidosis and mild hyperammonemia...

A sandwich FAU-LTA zeolite dual-layer membrane has been developed and used as a catalytic membrane reactor for the synthesis of dimethyl ether (DME). In the top H-FAU layer with mild acidity, methanol is dehydrated to DME. The other reaction product, water, is removed in situ through a hydrophilic Na-LTA layer, which is located between the porous alumina support and the H-FAU top layer. The combination of mild acidity with the continuous removal of water results in high methanol conversion (90.9 % at 310 °C) and essentially 100 % DME selectivity...

Herein, we report Rh(III)-catalyzed, N-amino (hydrazine)-directed C-H functionalization with α-diazo-β-ketoesters for access to the cinnoline scaffold. A diverse set of nondiscriminating conditions obtained for a highly efficient test transformation prompted use of a substrate-replacement technique for an in-depth search of experimental parameter space and pinpointing of the optimized conditions. A successive C-H activation/C-C coupling/intramolecular dehydration mechanistic sequence is proposed. The ability to perform gram-scale synthesis proves the synthetic utility of this simple, yet efficient, method...

Understanding how ticks survive the multitude of stresses experienced during winter is integral to predicting population dynamics and transmission of tick-borne pathogens. The American dog tick (Dermacentor variabilis), a predominant vector of Rocky Mountain spotted fever, overwinters in any of its post-egg life stages. In this study, we characterized the cold tolerance of larval D. variabilis and examined the effect of various acclimatory conditions on cold hardiness. Cold-shock survival during 2h exposure to various subzero temperatures was assessed and a lower lethal temperature of -20°C and a 50% mortality temperature near -16°C was established...

A highly efficient synthetic route to pterocarpenes and coumestans is described. BCl3-mediated dehydrative cyclization of 1,3-diaryloxyacetones under mild conditions permitted regioselective ring closure to afford 3-((2-iodoaryloxy)methyl)benzofurans which were converted to the corresponding pterocarpenes by Pd-catalyzed intramolecular direct arylation. The subsequent benzylic oxidation led to coumestans. This sequence was applied to the formal syntheses of coumestrol and the proposed structure of plicadin as well as total syntheses of flemichapparins B and C...

Aging-associated kidney disease is usually considered a degenerative process associated with aging. Recently, it has been shown that animals can produce fructose endogenously, and that this can be a mechanism for causing kidney damage in diabetic nephropathy and in association with recurrent dehydration. We therefore hypothesized that low-level metabolism of endogenous fructose might play a role in aging-associated kidney disease. Wild-type and fructokinase knockout mice were fed a normal diet for 2 yr that had minimal (<5%) fructose content...

Extrapontine myelinolysis (EPM) is an uncommon disorder in children, with few pediatric cases reported to date. We report the first case of an infant with EPM without central pontine myelinolysis (CPM) presenting with severe hypernatremia. On admission, the infant had impaired consciousness, mild dehydration, and severe hypernatremia (190 mmol/L). The following day, the patient developed abnormal involuntary movements. Brain magnetic resonance imaging (MRI) confirmed EPM without CPM. He recovered without sequelae, and clinical examinations were within normal limits approximately 6 months after discharge...

We have found that activating either 2,3-bis(2,3,4-trimethoxyphenyl)cyclopropenone or 2,3-bis(2,3,4-trimethoxyphenyl)cyclopropene-1-thione with oxalyl bromide results in the formation of a species that promotes the glycosylation between 2,6-dideoxy-sugar hemiacetals and glycosyl acceptors in good yield and high α-selectivity. Both reactions are mild and tolerate a number of sensitive functional groups including highly acid-labile 2,3,6-trideoxy-sugar linkages.
