Jyh-Hong Lee 2010-01-01 Full Text Available The IL-1R/TLR family has been receiving considerable attention as potential regulators of inflammation through their ability to act as either activators or suppressors of inflammation. Asthma is a chronic inflammatory disease characterized by airway hyperresponsiveness, allergic inflammation, elevated serum total, allergen-specific IgE levels, and increased Th2 cytokine production. The discovery that the IL-1RI–IL-1 and ST2–IL-33 pathways are crucial for allergic inflammation has raised interest in these receptors as potential targets for developing new therapeutic strategies for bronchial asthma.
This paper discusses the current use of neutralizing mAb or soluble receptor constructs to deplete cytokines, the use of neutralizing mAb or recombinant receptor antagonists to block cytokine receptors, and gene therapy from experimental studies in asthma. Targeting IL-1RI–IL-1 as well as ST2–IL-33 pathways may promise a disease-modifying approach in the future. Pitmon, E; Stephens, G; Parkhurst, S J; Wolf, F W; Kehne, G; Taylor, M; Lebestky, T 2016-03-01 Drosophila groom away debris and pathogens from the body using their legs in a stereotyped sequence of innate motor behaviors. Here, we investigated one aspect of the grooming repertoire by characterizing the D1 family dopamine receptor, DopR. Removal of DopR results in decreased hind leg grooming, as substantiated by quantitation of dye remaining on mutant and RNAi animals vs. Controls and direct scoring of behavioral events. These data are also supported by pharmacological results that D1 receptor agonists fail to potentiate grooming behaviors in headless DopR flies.

DopR protein is broadly expressed in the neuropil of the thoracic ganglion and overlaps with TH-positive dopaminergic neurons. Broad neuronal expression of dopamine receptor in mutant animals restored normal grooming behaviors. These data provide evidence for the role of DopR in potentiating hind leg grooming behaviors in the thoracic ganglion of adult Drosophila.
This is a remarkable juxtaposition to the considerable role of D1 family dopamine receptors in rodent grooming, and future investigations of evolutionary relationships of circuitry may be warranted. © 2016 The Authors.

Previous work has shown that the LPP reflects the modulation of activity in extrastriate visual cortical structures, but little is known about the source of that modulation. The present study investigated whether beta-adrenergic receptors are involved in the generation of the LPP. We used a genetic individual differences approach (experiment 1) and a pharmacological manipulation (experiment 2) to test the hypothesis that the LPP is modulated by the activation of β-adrenergic receptors.
In experiment 1, we found that LPP amplitude depends on allelic variation in the β1- receptor gene polymorphism. In experiment 2, we found that LPP amplitude was modulated by the β-blocker propranolol in a direction dependent on subjects' level of trait anxiety: In participants with lower trait anxiety, propranolol led to a (nonsignificant) decrease in the LPP modulation; in participants with higher trait anxiety, propranolol increased the emotion-related LPP modulation. These results provide initial support for the hypothesis that the LPP reflects the downstream effects, in visual cortical areas, of β- receptor-mediated activation of the amygdala. Javadi, Parastoo; Rezayof, Ameneh; Sardari, Maryam; Ghasemzadeh, Zahra 2017-07-01 The aim of the present study was to examine the possible role of nicotinic acetylcholine receptors of the dorsal hippocampus (CA1 regions), the medial prefrontal cortex or the basolateral amygdala in the effect of acute or sub-chronic stress on nicotine-induced conditioned place preference. Our results indicated that subcutaneous administration of nicotine (0.2 mg/kg) induced significant conditioned place preference. Exposure to acute or sub-chronic elevated platform stress potentiated the response of an ineffective dose of nicotine.
Pre-conditioning intra-CA1 (0.5-4 µg/rat) or intra-medial prefrontal cortex (0.2-0.3 µg/rat) microinjection of mecamylamine (a non-selective nicotinic acetylcholine receptor antagonist) reversed acute stress-induced potentiation of nicotine reward as measured in the conditioned place preference paradigm. By contrast, pre-conditioning intra-basolateral amygdala microinjection of mecamylamine (4 µg/rat) potentiated the effects of acute stress on nicotine reward. Our findings also showed that intra-CA1 or intra-medial prefrontal cortex, but not intra-basolateral amygdala, microinjection of mecamylamine (4 µg/rat) prevented the effect of sub-chronic stress on nicotine reward. These findings suggest that exposure to elevated platform stress potentiates the rewarding effect of nicotine which may be associated with the involvement of nicotinic acetylcholine receptors. It seems that there is a different contribution of the basolateral amygdala, the medial prefrontal cortex or the CA1 nicotinic acetylcholine receptors in stress-induced potentiation of nicotine-induced conditioned place preference.

We submit the first evidence that cysteine residues of homocysteine or acetylcysteine affect TRPC6 expression in human monocytes. That patients with chronic renal failure had significantly elevated homocysteine levels and TRPC6 mRNA expression levels in monocytes compared to control subjects.
We further observed that administration of homocysteine or acetylcysteine significantly increased TRPC6 channel protein expression compared. To control conditions. We therefore hypothesize that cysteine residues increase TRPC6 channel protein expression in humans. Yue, Lan; Xie, An; Bruzik, Karol S 2011-01-01 Purpose. Propofol (2,6-diisopropyl phenol), a widely used systemic anesthetic, is known to potentiate GABA(A) receptor activity in a number of CNS neurons and to produce changes in electroretinographically recorded responses of the retina. However, little is known about propofol's effects.
On specific retinal neurons. The authors investigated the action of propofol on GABA-elicited membrane current responses of retinal bipolar cells, which have both GABA(A) and GABA(C) receptors. Single, enzymatically dissociated bipolar cells obtained from rat retina were treated with propofol. + propofol) led to a progressive increase in peak response amplitude and, at higher propofol concentrations, additional changes that included a prolonged time course of response recovery.
Pre-exposure of the cell to perfusing propofol typically enhanced the rate of development of potentiation produced. Loeppky, Richard N; Shi, Jianzheng; Barnes, Charles L; Geddam, Sailaja 2008-02-01 Tolazoline (1-benzylimidazoline), a representative imidazoline-containing drug, reacts readily with nitrite in acetic acid to produce a complex product mixture. Fourteen compounds have been identified as products of this transformation when an 8-fold excess of HNO2 is used. The products, which include N-nitrosoamides, esters, alcohols, and phenylacetic acid, are rationalized as arising from a cascade of reactive diazonium ions. N-Nitrosotolazoline can be isolated from the nitrosation reaction in good yield when the mixture is extracted with CH2Cl2 as the transformation progresses. It nitrosates much more rapidly (50x) than tolazoline to give, among other products, the oxime 1-( N-nitroso-2-imidazolinyl)benzylidenehydroxylamine, which can also be produced in good yield from the reaction of tolazoline with isopropyl nitrite.
At low substrate and nitrite concentrations, the main reaction products are N-nitrosotolazoline, its decomposition product N-2-hydroxyethylphenylacetamide, the above-mentioned oxime, phenyl acetic acid, and 2-hydroxyethyl phenylacetate. The tolazoline nitrosation rate in three buffer systems has been determined at pH 3.4 and 37 degrees C ( kobs = 6.25 x 10 (-5) s (-1) in 0.5 M acetate buffer with a 10.
NO2(-) = 250 mM). Because N-nitrosotolazoline exhibits the chemical properties of a direct-acting mutagen and carcinogen, we have used the rate data to estimate its level of formation at nitrite concentrations.

That depends on where we live and the challenges to being “faithful.” It is not identical in the US with what may be required in So. America, or Europe, or Asia or especially the Middle East.
What worldly powers are forcing the church to be the “sanctified community” Bonhoeffer envisioned? In Europe it may be the increasing hostility towards a refugee catastrophe unmatched since WWII.
In Asia it may be economic priorities, or genocidal starvation by dictators hungry for world power. In the Middle East it is an increasing fundamentalism in Islam which lusts for encompassing power through violence so abhorrent we in the civilized world can hardly believe it.
In the USA, whatever it is (and there are several prominent candidates), it must include the following (shades of Nazi Germany): the persecution of “inferior” races, LGBTQ persons, government refusal to care for the most vulnerable in the name of national security, unjustified spending on armaments to ensure the military-industrial complex is cared for, and so on and so on. “Give us eyes to see” what we do not wish to see. Loose Follower – Other Paleo followers take a more lax approach, and realize that in our modern world it’s not practical to eat exactly like a caveman, and they take some modern comforts into their Paleo approach.
