With potassium hydroxide (KOH) as catalyst, hydroxypropyl guar gum (HPG) was successfully prepared under homogenous conditions in an ionic liquid 1-butyl-3-methylimidazolium chloride (BmimCl). The value of degree of molar substitution (MS) of HPG, which was determined by means of 1H NMR, was eas...

Herein we report the synthesis and X-ray characterization of a neutral mercury(II) complex of composition [Hg(L)2]n (1), [L = N1-(3-hydroxypropyl)-5-fluorouracilate]. The Hg(II) is bound to the N(3) atoms of both ligands in an essentially linear geometry. Mercury also interacts through short con...

Binary liquid–liquid equilibria for 10 systems containing an ionic liquid (1-(3-hydroxypropyl)pyridinium bis(trifluoromethylsulfonyl)-amide and 1-(3-hydroxypropyl)pyridinium trifluorotris(perfluoroethyl)phosphate) with a hydrocarbon (n-hexane, n-heptane, cyclohexane, benzene, toluene) were meas...

The aim of this study was to investigate urinary 3-hydroxypropyl mercapturic acid (3-HPMA), a metabolite of acrolein, as a novel biomarker in acute spinal cord injury (ASCI) due to intervertebral disc herniation in dogs. Urine from 10 client-owned dogs with ASCI collected at presentation and 10 ...

Nanobud assembled copper oxide mesostructures have been synthesized on a stainless steel substrate via a simple chemical bath deposition method and characterized for crystal structure, surface morphology and oxidation state by X-ray diffraction, field emission scanning electron microscopy, nitro...

A convenient method is described for the rapid synthesis of 5-(4-methoxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OMe) from anethole and elemental sulfur using microwave irradiation. Various reaction conditions were applied to reduce the reaction time from several hours to 10 min, resulting in an im...

Despite the high prevalence of aggression across a wide range of disorders, there is a severe lack of pharmacological treatments. Recent rodent studies have shown both centrally and peripherally administered oxytocin is effective in reducing territorial aggression, an adaptive form of aggression...

The neuropeptide Oxytocin (ΟΤ) is involved as a neurohormone, a neurotransmitter, or a neuromodulator in an extensive range of central and peripheral effects, complex emotional and social human behaviors, memory and learning processes. It is implicated in homeostatic, neuroadaptive processes a...

BackgroundMorbidity and mortality from cardiovascular disease is a typical phenomenon in the elderly, and are related to unfavorable genetic, hormonal and environmental (lifestyle) interactions. In this context, oxytocin (OT) seems plays a key role in the development of CVD by performing importa...

IntroductionRetained placenta can be defined as lack of expulsion of the placenta within 30 min of delivery of the infant. It is a significant cause of maternal mortality and morbidity throughout the developing world.

Oxytocin mediates its behavioural effects via the centrally expressed oxytocin receptor (OTR). Oxytocin signalling has been implicated in multiple disorders involving centrally regulated pathways, including obesity, autism, schizophrenia and depression. The OTR has been described to have a compl...

In addition to its role in childbirth labor and lactation, oxytocin is a well-known neurohormone, having several prosocial effects. Moreover, oxytocin seems to play a significant modulatory role in painful experiences, due to its participation in central and peripheral processing of nociceptive ...

Previous research suggests a dynamic regulatory relationship between oxytocin and cortisol, but the specific nature of this relationship and its context-specificity have not been fully specified. In the present study, we repeatedly assessed both salivary oxytocin and salivary cortisol during two...

Oxytocin is a hormone of interest in reproduction, but also in the field of psychology and behavior, being considered as a biomarker of positive emotions. Saliva can be a non-invasive sample to measure oxytocin very useful in species as the pig where blood collection can produce a high degree of...

Cardiovascular disease (CVD) remains the leading cause of death worldwide, despite multiple treatment options. In addition to elevated lipid levels, oxidative stress and inflammation are key factors driving atherogenesis and CVD. New strategies are required to mitigate risk and most urgently for...

More than 300 million people are suffering from depression, one of the civilization diseases in the 21st century. Serotonin 5-HT1AR and dopamine D2R play an important role in the treatment and pathogenesis of depression. Moreover, in recent years, the efficacy of dual 5-HT1A/D2 receptors ligands...

Acidolytic cleavage of C-terminal Cys(Acm)-containing tripeptides from the Wang (HMP) resin can lead to partial deprotection of the Acm group and subsequent disulfide formation. The presence of water and the type of scavenger used in the cocktail mixture were found to play a role in the extent o...

Some T cell epitopes become inactive when their thiols are blocked with various irreversible reagents (Régnier-Vigouroux, 1988; Maillère, 1992; Maillère et al., 1993). Blocking protein and peptide thiols with BCNP (Boc-Cys(Npys)-OH) constitutes a most appropriate strategy when searching for t...

Silver complexes of halocarbons and silver salts of halogenated organic acids (for example, silver chloroacetate) often show secondary Ag⋯X bonding interactions and unusually low 35Cl NQR frequencies, due to secondary bonding of chlorines to silver atoms. The crystal structure of silver dichloro...

The syntheses of the 7β-hydroxy metabolite of ORG OD14 (Livial®), (3α,7β,17α)-7-methyl-19-norpregn-5(10)-en-20-yne-3,7,17-triol (35), and its 7-epimer, (3α,7α,17α)-7-methyl-19-norpregn-5(10)-en-20-yne-3,7,17-triol (11), are described.
