Pain, opioid use, depressive symptoms, and mortality in adults living in precarious housing or homelessness: a longitudinal prospective study.

Pain and related consequences could contribute to comorbid illness and premature mortality in homeless and precariously housed persons. We analyzed longitudinal data from an ongoing naturalistic prospective study of a community-based sample (n = 370) to characterize risk factors and consequences of bodily pain. The aims were to describe bodily pain and associations with symptoms and psychosocial function, investigate factors that may increase or ameliorate pain, and examine the consequences of pain for symptoms, functioning, and all-cause mortality.

Glucose Treatment Targets in Pregnancy - A Review of Evidence and Guidelines.

Background: Maternal diabetes mellitus during pregnancy is associated with an increased risk of pregnancy complications for both the mother and the fetus. One of the most prevalent complications is pathological fetal growth, and particularly infants are born large for gestational age (LGA), which leads to problematic deliveries, including the need for caesarean section, instrumental delivery, and further perinatal complications. Glucose monitoring during pregnancy is essential for ensuring appropriate glycaemic control and to reduce these associated risks.

Cytoplasmic long noncoding RNAs are differentially regulated and translated during human neuronal differentiation.

The expression of long noncoding RNAs is highly enriched in the human nervous system. However, the function of neuronal lncRNAs in the cytoplasm and their potential translation remains poorly understood. Here we performed Poly-Ribo-Seq to understand the interaction of lncRNAs with the translation machinery and the functional consequences during neuronal differentiation of human SH-SY5Y cells.

Lechebnaia pedagogika: The Concept and Practice of Therapy in Russian Defectology, c. 1880-1936.

Therapy is not simply a domain or form of medical practice, but also a metaphor for and a performance of medicine, of its functions and status, of its distinctive mode of action upon the world. This article examines medical treatment or therapy (in Russian lechenie), as concept and practice, in what came to be known in Russia as defectology (defektologiia) - the discipline and occupation concerned with the study and care of children with developmental pathologies, disabilities and special needs. Defectology formed an impure, occupationally ambiguous, therapeutic field, which emerged between different types of expertise in the niche populated by children considered 'difficult to cure', 'difficult to teach', and 'difficult to discipline'.

Evaluation of JAK3 Biology in Autoimmune Disease Using a Highly Selective, Irreversible JAK3 Inhibitor.

Reversible janus associated kinase (JAK) inhibitors such as tofacitinib and decernotinib block cytokine signaling and are efficacious in treating autoimmune diseases. However, therapeutic doses are limited due to inhibition of other JAK/signal transducer and activator of transcription pathways associated with hematopoiesis, lipid biogenesis, infection, and immune responses. A selective JAK3 inhibitor may have a better therapeutic index; however, until recently, no compounds have been described that maintain JAK3 selectivity in cells, as well as against the kinome, with good physicochemical properties to test the JAK3 hypothesis in vivo.

V. M. BEKHTEREV IN RUSSIAN CHILD SCIENCE, 1900S-1920S: "OBJECTIVE PSYCHOLOGY"/"REFLEXOLOGY" AS A SCIENTIFIC MOVEMENT.

In the early 20(th) century the child population became a major focus of scientific, professional and public interest. This led to the crystallization of a dynamic field of child science, encompassing developmental and educational psychology, child psychiatry and special education, school hygiene and mental testing, juvenile criminology and the anthropology of childhood. This article discusses the role played in child science by the eminent Russian neurologist and psychiatrist Vladimir Mikhailovich Bekhterev.

Overcoming mutagenicity and ion channel activity: optimization of selective spleen tyrosine kinase inhibitors.

Development of a series of highly kinome-selective spleen tyrosine kinase (Syk) inhibitors with favorable druglike properties is described. Early leads were discovered through X-ray crystallographic analysis, and a systematic survey of cores within a selected chemical space focused on ligand binding efficiency. Attenuation of hERG ion channel activity inherent within the initial chemotype was guided through modulation of physicochemical properties including log D, PSA, and pKa.

Etanercept ameliorates inflammation and pain in a novel mono-arthritic multi-flare model of streptococcal cell wall induced arthritis.

Background: The impact of anti-TNF, corticosteroid and analgesic therapy on inflammation and pain was evaluated in a novel mono-arthritic multi-flare rat Streptococcal Cell Wall (SCW) model using Etanercept, Dexamethasone and Buprenorphine.

Methods: Multiple flares of arthritis were induced with an intra-articular injection of SCW in the hind ankle on day 1, followed by intravenous challenges on days 21 and 42. Inflammation and pain were monitored in the hind paws.

The preclinical efficacy, selectivity and pharmacologic profile of MK-5932, an insulin-sparing selective glucocorticoid receptor modulator.

Glucocorticoids are used widely in the treatment of inflammatory diseases, but use is accompanied by a significant burden of adverse effects. It has been hypothesized that gene- and cell-specific regulation of the glucocorticoid receptor by small molecule ligands could be translated into a therapeutic with an improved risk-benefit profile. MK-5932 is a highly selective glucocorticoid receptor modulator that is anti-inflammatory in vivo with an improved profile on glucose metabolism: Bungard et al.

The discovery of novel 8-azabicyclo[3.2.1]octan-3-yl)-3-(4-chlorophenyl) propanamides as vasopressin V1A receptor antagonists.

The discovery of a novel series of 8-azabicyclo[3.2.1]octan-3-yl)-3-(4-chlorophenyl) propanamide antagonists of the vasopressin V(1A) receptor is disclosed.

Turning pedagogy into a science: teachers and psychologists in late imperial Russia (1897-1917).

The article explores the Russian teachers' tortuous campaign at the beginning of the twentieth century to rise above the status of "semiprofessionals" by rooting the legitimacy of their professional expertise, training institutions, and working practices in the authority of "science." This involved a radical reshaping of traditional pedagogy and its fusion with new, controversial approaches to child psychology. It also led to a proliferation of teacher-training courses and conferences devoted to "pedagogical psychology," "experimental pedagogy," and "pedology.

The hypnotic, electroencephalographic, and antinociceptive properties of nonpeptide ORL1 receptor agonists after intravenous injection in rodents.

Background: Agonists at the opioid receptor-like receptor 1 (ORL1) induce motor impairment, sedation, and loss of righting reflex (LRR) in rodents. This receptor may provide a novel target in the field of anesthesia.

Methods: We examined the hypnotic, electroencephalographic (EEG), and antinociceptive effects of two IV administered nonpeptide ORL1 agonists, (Ro 65-6570 and Org 26383), using LRR in mice and rats, percent EEG burst suppression in rats, and formalin paw test in mice.

Novel water soluble 2,6-dimethoxyphenyl ester derivatives with intravenous anaesthetic activity.

A number of water soluble bis-amino-2,6-dimethoxyphenyl ester derivatives were found to exhibit improved anaesthetic activity in mice relative to propofol 1. Of the analogues disclosed, 44 was further profiled in rodents and found to be a superior agent to propofol for the induction and maintenance of anaesthesia.

A1 adenosine receptor overexpression attenuates ischemia-reperfusion-induced apoptosis and caspase 3 activity.

We tested the hypothesis that myocardial ischemia-reperfusion (I/R)-induced apoptosis is attenuated in transgenic mice overexpressing cardiac A(1) adenosine receptors. Isolated hearts from transgenic (TG, n = 19) and wild-type (WT, n = 22) mice underwent 30 min of ischemia and 2 h of reperfusion, with evaluation of apoptosis, caspase 3 activity, function, and necrosis. I/R-induced apoptosis was attenuated in TG hearts.

Gene expression profile of mouse myocardium with transgenic overexpression of A1 adenosine receptors.

Transgenic mice with cardiac-specific overexpression of adenosine A(1) receptors (A(1)AR) have demonstrated metabolic and functional tolerance to myocardial ischemia. We utilized cDNA microarrays to test the hypothesis that the cardioprotective mechanism(s) of A(1) overexpression involves altered gene expression. Total RNA extracted from the left ventricles from A(1) transgenic (n = 4) and wild-type (n = 6) mice was hybridized to Affymetrix mgU74A chips.

A1 adenosine receptor overexpression decreases stunning from anoxia-reoxygenation: role of the mitochondrial K(ATP) channel.

Myocardial A1 adenosine receptor (A1AR) overexpression protects hearts from ischemia-reperfusion injury; however, the effects during anoxia are unknown. We evaluated responses to anoxia-reoxygenation in wild-type (WT) and transgenic (Trans) hearts with approximately 200-fold overexpression of A1ARs. Langendorff perfused hearts underwent 20 min anoxia followed by 30 min reoxygenation.

Cardiac overexpression of A1-adenosine receptor protects intact mice against myocardial infarction.

Previous studies have shown that high-level (300-fold normal) cardiac overexpression of A1-adenosine receptors (A1-ARs) in transgenic (TG) mice protects isolated hearts against ischemia-reperfusion injury. However, this high level of overexpression is associated with bradycardia and increased incidence of arrhythmia during ischemia in intact mice, which interfered with studies to determine whether this line of TG mice might also be protected against myocardial infarction (MI) in vivo. For these studies, we therefore selected a line of TG mice that overexpresses the A1-AR at more moderate levels (30-fold normal), which affords cardioprotection in the isolated heart while minimizing bradycardia and arrhythmia during ischemia in intact mice.

Water-soluble propofol analogues with intravenous anaesthetic activity.

Propofol (2,6-diisopropylphenol) is a widely used intravenous anaesthetic that is formulated as an emulsion since it lacks water solubility. We report a range of water-soluble analogues of propofol, containing a para-alkylamino substituent, which retain good intravenous anaesthetic activity in rodents.

Transgenic overexpression of cardiac A(1) adenosine receptors mimics ischemic preconditioning.

The role of A(1) adenosine receptors (A(1)AR) in ischemic preconditioning was investigated in isolated crystalloid-perfused wild-type and transgenic mouse hearts with increased A(1)AR. The effect of preconditioning on postischemic myocardial function, lactate dehydrogenase (LDH) release, and infarct size was examined. Functional recovery was greater in transgenic versus wild-type hearts (44.

Local anesthetic inhibition of m1 muscarinic acetylcholine signaling.

Background: Local anesthetics inhibit lipid mediator signaling (lysophosphatidate, thromboxane) by acting on intracellular domains of the receptor or on the G protein. On receptors for polar agonists, the ligand-binding pocket could form an additional site of interaction, possibly resulting in superadditive inhibition. The authors therefore investigated the effects of local anesthetics on m1 muscarinic receptor functioning.

Transgenic A1 adenosine receptor overexpression increases myocardial resistance to ischemia.

Activation of myocardial A1 adenosine receptors (A1AR) protects the heart from ischemic injury. In this study transgenic mice were created using the cardiac-specific alpha-myosin heavy chain promoter and rat A1AR cDNA. Heart membranes from two transgene positive lines displayed approximately 1,000-fold overexpression of A1AR (6,574 +/- 965 and 10,691 +/- 1,002 fmol per mg of protein vs.

Anesthetic activity of novel water-soluble 2 beta-morpholinyl steroids and their modulatory effects at GABAA receptors.

(3 alpha,5 alpha)-3-Hydroxypregnan-20-ones and (3 alpha,5 alpha)-3-hydroxypregnane-11,20-diones bearing a 2 beta-morpholinyl substituent were synthesized, and the utility of these steroids as anesthetic agents was evaluated through determination of their potency and duration of hypnotic activity in mice after intravenous administration. Alkylation of the morpholinyl substituent or chlorination at C-21 afforded the novel amino steroids (2 beta,3 alpha,5 alpha)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)-pregnane-11,20-dione (19) and (2 beta,3 alpha,5 alpha)-21-chloro-3-hydroxy-2-(4-morpholinyl)pregnan-20-one (37) that were more potent and advantageously produced shorter sleep times than related compounds which were previously reported. Furthermore, salts of these and other amino steroids generally retained good aqueous solubility.

The anaesthetic action and modulation of GABAA receptor activity by the novel water-soluble aminosteroid Org 20599.

The anaesthetic profile of a novel water-soluble aminosteroid, Org 20599 [(2 beta, 3 alpha, 5 alpha)-21-chloro-3-hydroxy-2-(4-morpholinyl)pregnan-20-one methanesulphonate], and the ability of the compound to allosterically regulate the activity of the GABAA receptor, have been studied in comparison to the properties of established intravenous general-anaesthetic agents. Intravenously administered Org 20599 produced a rapid onset, short duration loss of the righting reflex in mice. The anaesthetic potency of Org 20599 was comparable to that of the steroids 5 alpha-pregnan-3 alpha-ol-20-one or alphaxalone, and exceeded that of propofol, thiopentone or pentobarbitone.

Changes in myocardial A1 adenosine receptor and message levels during fetal development and postnatal maturation.

Previously we have shown myocardial adenosine A1 receptors are up-regulated during the newborn period. The timing of the increase or the mechanism of the changes are not known. The purpose of the present study was to (1) determine the time course of increased A1 adenosine receptors during fetal development and (2) determine if A1 adenosine receptor regulation is secondary to changes in A1 receptor mRNA levels.

Replisome pausing in mutagenesis.

E. coli cells containing a temperature-sensitive dnaE mutation, in the alpha-subunit of holoenzyme DNA polymerase III, do not survive at the restrictive temperature. Such cells may survive in the presence of the pcbA1 mutation, an allele of the gyrB gene.
