Effect of L-azetidine-2-carboxylic acid on glycosylations of collagen in chick-embryo tendon cells. (1/17)

The glycosylations of hydroxylysine during collagen biosynthesis in isolated chick-embryo tendon cells were studied by using pulse-chase labelling experiments with [14C]-lysine. The hydroxylation of lysine and the glycosylations of hydroxylysine continued after a 5 min pulse label for up to about 10 min during the chase period. These data differ from those obtained previously in isolated chick-embryo cartilage cells, in which, after a similar 5 min pulse label, these reactions continued during the chase period for up to about 20 min. The collagen synthesized by the isolated chick-embryo tendon cells differed markedly from the type I collagen of adult tissues in its degree of hydroxylation of lysine residues and glycosylations of hydroxylysine residues. When the isolated tendon cells were incubated in the presence of L-azetidine-2-carboxylic acid, the degree of glycosylations of hydroxylysine during the first 10 min of the chase period was identical with that in cells incubated without thcarboxylic acid for at least 60 min, whereas no additional glycosylations took place in the control cells after the 10 min time-point. As a consequence, the collagen synthesized in the presence of this compound contained more carbohydrate than did the collagen synthesized by the control cells. Additional experiments indicated that azetidine-2-carboxylic acid did not increase the collagen glycosyltransferase activities in the tendon cells or the rate of glycosylation reactions when added directly to the enzyme incubation mixture. Control experiments with colchicine indicated that the delay in the rate of collagen secretion, which was observed in the presence of azetidine-2-carboxylic acid, did not in itself affect the degree of glycosylations of collagen. The results thus suggest that the increased glycosylations were due to inhibition of the collagen triple-helix formation, which is known to occur in the presence of azetidine-2-carboxylic acid.  (+info)

Incorporation of L-azetidine-2-carboxylic acid into hemoglobin in rabbit reticulocytes in vitro. (2/17)

L-Azetidine-2-carboxylic acid is the naturally occurring lower homologue of L-proline. Reticulocytes from anemic rabbits incubated with DL-[14-C]azetidine-2-carboxylic acid synthesized radiolabeled hemoglobin, which when isolated from cell lysates co-chromatographed with unlabeled hemoglobin on Sephadex G-100 columns. Amino acid analysis of hemoglobin from reticulocytes incubated with DL-[14-C]-azetidine-2-carboxylic acid suggested that the homologue was incorporated into hemoglobin intact and unaltered. Alternatively, another amino acid analogue, 1-aminocyclopentane-[1-14-C]carboxylic acid, which is purported to be a valine antagonist, was not incorporated into hemoglobin under these conditions. Incubation of reticulocytes with 1, 5, and 10 mM L-azetidine-2-carboxylic acid reduced L-[U-14-C]proline (0.10 mM) incorporation into hemoglobin by 25, 58, and 72%, respectively. Conversely, 1.45 and 145 muM L-proline reduced radiolabeled azetidine-2-carboxylic acid (0.8 mM) in corporation into hemoglobin by 45 and 92%, respectively. Incorporation of L-[U-14-C]leucine and L-[U-14-C]lysine (0.1 mM each) into hemoglobin was unaffected at these concentrations of L-azetidine-2-carboxylic acid. These results suggest that L-azetidine-2-carboxylic acid is incorporated into hemoglobin without reducing the rate of globin synthesis in rabbit reticulocytes in vitro. The alpha and beta chains of hemoglobin into which [14-C]azetidine-2-carboxylic acid had been incorporated in rabbit reticulocytes in vitro were resolved electrophoretically on sodium dodecyl sulfate-polyacrylamide gels. The ratio of total radioactivity in the alpha and beta chains separately extracted from gels was in good agreement with the known 7:4 ratio of prolyl residues in the respective chains. Autoradiograms of two-dimensional tryptic peptide maps of rabbit globin into which either [14-C]azetidine-2-carboxylic acid or [14-C]proline had been incorporated showed nearly identical patterns of radioactivity. These results suggest that azetidine-2-carboxylic acid substitutes specifically for prolyl residues during in vitro hemoglobin synthesis in rabbit reticulocytes.  (+info)

Antihypertensive effect of CS-905, a novel dihydropyridine calcium blocker, in conscious hypertensive dogs. (4/17)

CS-905, (+-)-3-(1-diphenylmethylazetidin-3-yl)5-isopropyl 2-amino-1,4-dihydro-6-methyl-4-(m-nitrophenyl)-3,5-pyridine-dicarboxy lat e, is a novel dihydropyridine calcium blocker. Both CS-905 and nicardipine, when administered orally, produced a dose-dependent fall of blood pressure in conscious perinephritic hypertensive dogs. Unlike the hypotensive effect of nicardipine, that of CS-905 has a gradual onset and is long-lasting, with little increase in the heart rate and plasma renin activity (PRA). The lack of both tachycardia and increase of PRA is probably mostly due to the slow onset of antihypertensive action following CS-905.  (+info)

Effects of a new thyrotropin-releasing hormone derivative on behavioral changes after focal cerebral ischemia in rats. (6/17)

We observed the effects of a new thyrotropin-releasing hormone derivative, YM-14673 (N alpha-[[(S)-4-oxo-2-azetidinyl]carbonyl]-L-histidyl-L-prolinamide dihydrate), on behavioral changes in rats for 3 weeks after focal cerebral ischemia. Under halothane anesthesia, the left middle cerebral artery was occluded via a transretro-orbital approach. YM-14673 was administered just after the operation and once a day for 3 weeks. Neurologic deficits, including hemiplegia and abnormal posture, and disturbance of passive avoidance learning were present in solvent-treated control rats for the entire 3 weeks. YM-14673 at 0.1 or 0.3 mg/kg i.p. or 1 mg/kg p.o. significantly accelerated the recovery of neurologic deficits and ameliorated cognitive disturbance compared with the solvent-treated controls although the drug at 0.1 and 0.3 mg/kg i.p. did not influence the size of the ischemic infarct. YM-14673 mitigated the behavioral disturbances in this model of chronic focal cerebral ischemia. We also discuss the suitability of this model for the evaluation of drugs.  (+info)

Beneficial renal effects of CS-905, a novel dihydropyridine calcium blocker, in SHR. (7/17)

CS-905 is a potent dihydropyridine calcium blocker that has a gradual and long-lasting antihypertensive action with little tachycardia in SHR. In this study, we investigated chronic and acute effects of CS-905 on renal functions in SHR. To examine the chronic effects, 23 week-old male SHR were treated with CS-905 (1 or 3 mg/kg/day, p.o.) or 0.3% CMC (carboxymethylcellulose). After the 15 week-treatment, the agent dose-relatedly lowered systolic blood pressure measured 24 hr after the final administration (184 +/- 2 and 173 +/- 3 mmHg at 1 and 3 mg/kg/day vs. 218 +/- 4 mmHg for the control group). Natriuresis and the reduction of urinary protein excretion were also observed in the CS-905 treated groups. Urinary NAG (N-acetyl-beta-D-glucosaminidase) activity tended to decrease, but not significantly. Histopathological changes observed in the SHR kidney were reduced by chronic treatment with CS-905. On a single oral administration in 38 week-old SHR, CS-905 caused natriuresis at a dose of 3 mg/kg, but did not affect urinary protein excretion and urinary NAG activity. These effects of CS-905 on renal functions may be beneficial in the treatment of hypertension.  (+info)

Interference with thyroid histogenesis by inhibitors of collagen synthesis. (8/17)

Histogenesis of thyroid follicles in the chick embryo begins with a penetration by cells of the mesenchymal capsule into a solid epithelial primordium. Before penetration occurs, slits containing fibrillar material form between the epithelial cells. The fibrillar material is an epithelial cell product as shown by its formation within channels that form in cultures of isolated epithelial primordia. The drugs L-azetidine-2-carboxylic acid (LACA) and alpha, alpha'-dipyridyl, which interfere with collagen synthesis, prevent the formation of fibrils in cultured epithelial primordia and in cultures of whole thyroids. Furthermore, mesenchymal cells do not invade when whole thyroid primordia are cultured in the presence of either drug. The effects of alpha, alpha'-dipyridyl are reversed by washing out the drug; the effects of LACA are reversed by incubation with equimolar or greater amounts of L-proline added to the medium along with the drug. The results are interpreted to mean that the fibrillar material is collagen of epithelial origin, that the collagen in some way plays a role in mesenchymal penetration of the epithelial primordium, and that the epithelium is responsible for the pattern of lobulation within the developing gland.  (+info)

Amlodipine causes marked coronary and peripheral arterial vasodilation (which leads to plasma leakage in dependent areas since the veins remain constricted). As happens with other dihydropyridine calcium blockers, this results in a small percentage of patients having a problem with pedal edema (Am J Med. 2004;116:35-43). The pedal edema is not related to congestive heart failure and responds only inconsistently to diuretics, but it is not harmful.Mungkin akan nmpk sedikit gemuk sbb berlaku edema/bengkak.. ...

Limited examples of the successful ring expansion of aziridines with sulfonium ylides to generate azetidines are known, but typically result in functional groups on azetidine that are not broadly useful for downstream chemistry. Described here is an investigation into the scope of this reaction including the discovery that N-activated 2-methoxy ester functionalised aziridines are not compatible with this protocol. Advances have also been made in understanding the reactivity of azirines with rhodium carbenoids to generate azetines from successful ring expansion, or N-vinylimine from ring opening.. An alternative route to azetidines from the 1,3-cleavage of azabicyclo[1.1.0]butanes is described, along with a proposed route to highly functionalised azetidines with control over the absolute configuration at each step. Early success reacting a range of reagents with an azabicyclo[1.1.0]butane of moderate steric bulk has been shown, as well as early steps towards a novel azetidine 3-sulfonamide ...

The project aims to develop simple and cost-efficient diagnostic assays for the detection and monitoring of PCa. Our on-going research efforts aim to utilize the detection of prostate specific targets and aberrant glycosylations on EVs as a novel source of cancer biomarkers, which have previously been found to provide enhanced specificity for other cancers. Glycosylation changes are a well-known hallmark in cancer development and progression, and can enable the specific detection of EV subpopulations originating from tumor cells. The objectives will include the identification and detection of tissue and disease specific EV-subsets with the use of novel bioaffinity reagents (lectins and antibodies).. The project will include the formulation and clinical validation of in vitro diagnostics assays of biological fluids with decisively improved capability for sensitive and specific detection of PCa tumor derived biomarker isoforms, thus providing superior tools for early detection/screening of PCa as ...

Effects of opioid peptides on behavioral changes induced by stressful situations were investigated. [D-Ala2,Met5]-enkephalinamide and [D-Ala2,D-Leu5]-enkephalin, degrading-enzyme-resistant derivatives of methionine-enkephalin and leucine-enkephalin, respectively, significantly attenuated both environment-induced conditioned suppression of motility and forced swimming-induced immobility in a dose-dependent manner. The [D-Ala2,Met5]-enkephalinamide- and [D-Ala2,D-Leu5]-enkephalin-induced attenuations were antagonized by naloxone at different doses.

N2 - In this study we analyzed the effects of melatonin (Mel, 1 mg/kgip) on behavioral changes as well as cell and oxidative damage prompted by bilaterally olfactory bulbectomy. Olfactory bulbectomy caused an increase in lipid peroxidation products and caspase-3, whereas it prompted a decrease of reduced glutathione (GSH) content and antioxidative enzymes activities. Additionally, olfactory bulbectomy induced behavioral changes characterized by the enhancement of immobility time in the forced swim test and hyperactivity in the open field test. All these changes were normalized by treatment of Mel (14 days). Our data show that Mel has a beneficial neuropsychiatric action ...

Hello All, For me karate is a martial art, so therefore training is fighting, and fighting (in the healthy sense that it leads away from fear and paranoia) -as in combat sports. So when we perform our drills and basic techniques, we are putting them into a context where we can apply them against each other in such a way as to develop the underlying delivery system of the karate skills, and to develop our athleticism. In effect, what we do looks like MMA in a gi. I enjoy that game of using stand-up, clinch, ground, and wall/cage techniques together. Although we use our karate in this manner, what we do is not MMA, as no one at my gym competes in the cage, nor do we want to. We just enjoy the game. We are developing the physical skill sets required for fighting and self-defence (when in breaks down into fighting) in a fun and light manner. I emphasize athletic output with the use of non-damaging fighting technique (think as Judo was to the older battlefield Ju-Jitsu) to develop the qualities so ...

Abstract: Gaining access to stereodefined deoxy-sugar containing oligosaccharides, such as those containing 2,6-dideoxy and 2,3,6-trideoxy motifs, remains a formidable challenge. This is largely due to the difficulties associated with controlling the selectivity of glycosylations using deoxy-sugar donors. Herein, the development of three generations of reagent-controlled approaches utilizing cyclo... read morepropenium cations are described. Chapter 2 describes our first-generation approach which utilized a 3,3-dichloro-1,2-diphenylcyclopropene/tetrabutylammonium iodide (TBAI) promoter system for α-selective glycosylations. These substrates reacted with a range of glycosyl acceptors to afford products in 55 to 99% yield, with selectivities ranging from 3:1 α:β to all α, determined by NMR. In chapter 3 we describe how we improved upon the method by utilizing a 3,3-dibromo-1,2-diphenylcyclopropenone/TBAI system. This latter system activated deoxy-sugar donors to react with a range of glycosyl ...

Previously: v4.16.. Linux kernel v4.17 was released last week, and here are some of the security things I think are interesting:. Jailhouse hypervisor. Jan Kiszka landed Jailhouse hypervisor support, which uses static partitioning (i.e. no resource over-committing), where the root cell spawns new jails by shrinking its own CPU/memory/etc resources and hands them over to the new jail. Theres a nice write-up of the hypervisor on LWN from 2014.. Sparc ADI. Khalid Aziz landed the userspace support for Sparc Application Data Integrity (ADI or SSM: Silicon Secured Memory), which is the hardware memory coloring (tagging) feature in Sparc M7. Id love to see this extended into the kernel itself, as it would kill linear overflows between allocations, since the base pointer being used is tagged to belong to only a certain allocation (sized to a multiple of cache lines). Any attempt to increment beyond, into memory with a different tag, raises an exception. Enrico Perla has some great write-ups on using ...

20.07.17. Tonights lesson brought my client to 10 hour point of his course, completing Basic Muay Thai for Martial Arts Cross Training. This is where I like to bring clients back to the self-protection line and look at ways to integrate their attribute training into this area.. This time I looked at one aspect of the fence - a posture termed the pleading fence by Geoff Thompson. I mention it briefly on my Cross Training in the Martial Arts DVD. It involves putting the hands up in a parallel position as if pleading. Such a tactic is often employed by some self-defence teachers who teach handgun disarms, where the hands frame the weapon. The problem with teaching a fence posture is that individuals can easily get hung up and fixated on that particular posture. Geoff Thompson told me that the stylization of the fence largely came from people seeing his diagrams and photos, and assuming that the fence was a static position. When I started seeing people using the fence as a blocking tool rather ...

What is CombatiX™?. CombatiX™ is unlike any other combatives system out there! CombatiX™ is not simply Martial Arts. Instead, it is a highly specialized self-protection system developed extensively over decades of practical combative experience. We have evaluated and refined the techniques taught it many special forces and law enforcement programs to create an easy-to-learn and highly effective system of defensive tactics.. We have incorporated extensive knowledge of anatomy and physiology into CombatiX™. Most existing programs are based on Martial Arts systems which incorporate a block/punch/kick mentality to fighting. In those systems, brute force is favored. Unfortunately, this means that one has to have superior strength and size to be effective. With CombatiX™, training is focused on attacking the weaknesses of the human body.. For those who need or want to incorporate weapons, there is no need to learn a different system with highly specialized stances and techniques. With ...

I work in the pharmaceutical industry as a scientist and thus am very familiar with genetic engineering. We use it to engineer cell lines to produce the protein biologicals we engineer as medicines, such as antibodies. It is a common and well known concept that the species that one produces those proteins in matters very much, ie, if you take a single gene and express it in various species of cell lines, you will not get the same final protein due to something called post translational modifications. For example, the protein may have parts of it cut off, it may be folded differently, different phosphorylations may occur, or glycosylations (sugars) will get added on in different patterns. Sometimes those differences have little effect, and sometimes those effects are quite huge - you just dont know until you test it. This is what a lot of geneticists fail to convey when talking about genetic engineering. Sure, when you move DNA from species to another, that DNA is all made of the same ...
