Processes by which phototrophic organisms use sunlight as their primary energy source. Contrasts with chemotrophic processes which do not depend on light and function in deriving energy from exogenous chemical sources. Photoautotrophy (or photolithotrophy) is the ability to use sunlight as energy to fix inorganic nutrients to be used for other organic requirements. Photoautotrophs include all GREEN PLANTS; GREEN ALGAE; CYANOBACTERIA; and green and PURPLE SULFUR BACTERIA. Photoheterotrophs or photoorganotrophs require a supply of organic nutrients for their organic requirements but use sunlight as their primary energy source; examples include certain PURPLE NONSULFUR BACTERIA. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; HETEROTROPHY; chemotrophy; or phototrophy) to utilize different sources to meet their nutrients and energy requirements.

Drug-protein binding and blood-brain barrier permeability. (1/549)

The permeability surface area (PS) product, an index of permeability of the blood-brain barrier (BBB), was measured by using the in situ perfusion method. In the cerebral circulation, the fraction of drug that permeates into the brain through the BBB is not only the unbound fraction but also the fraction dissociated from the protein in the perfusate. The sum of these two fractions, the apparent exchangeable fraction, was estimated by fitting the parameters of the BBB permeability under the condition of varying BSA concentrations in the perfusate. The unbound fraction of drugs in a buffer containing 0.5 mM BSA was measured by using the ultrafiltration method in vitro, and the apparent exchangeable fraction was measured in vivo by using the intracarotid artery injection method. The apparent exchange fraction was 100% for S-8510, 96.5% for diazepam, 90.9% for caffeine, 38.3% for S-312-d, 33.1% for propranolol, and 6.68% for (+)-S-145 Na, and each of these was higher than the corresponding unbound fraction in vitro in all drugs. The apparent exchangeable fractions, for example, were 8 times higher for diazepam and 38 times for S-312-d than the unbound fractions in vitro. The apparent exchangeable fraction of drugs was also estimated from the parameters obtained with the perfusion method. Because drugs can be infused for an arbitrary length of time in the perfusion method, substances with low permeability can be measured. The apparent exchangeable fractions obtained with this method were almost the same as those obtained with the intracarotid artery injection method.  (+info)

Influence of a new antiulcer agent, ammonium 7-oxobicyclo (2, 2, 1) hept-5-ene-3-carbamoyl-2-carboxylate (KF-392) on gastric lesions and gastric mucosal barrier in rats. (2/549)

Antiulcer effects of KF-392 were studied in several experimental gastric ulcer models in rats. It was found that KF-392 given orally at 1.0 to 5.0 mg/kg had a marked suppression on the developments of Shay ulcer as well as the aspirin-, stress-, and reserpine-induced gastric lesions. The influence of KF-392 on gastric mucosal barrier was also studied. A back diffusion of H+ into the gastric mucosa and a fall of transmucosal potential difference were induced with KF-392 given orally at the above mentioned doses. KF-392 given s.c. at 5.0 mg/kg showed no inhibition of Shay ulcer and no induction of back diffusion of H+ into the gastric mucosa.  (+info)

Group II metabotropic glutamate receptor activation attenuates traumatic neuronal injury and improves neurological recovery after traumatic brain injury. (4/549)

We examined the effects of modulating group II metabotropic glutamate receptors (mGluRs) on traumatic neuronal injury using both in vitro and in vivo models. Treatment with various selective group II mGluR agonists significantly decreased lactate dehydrogenase release, a marker of cell death, after traumatic injury to rat neuronal-glial cultures; injury-induced increases in cyclic AMP and glutamate levels were also significantly reduced by a group II agonist. The neuroprotective effects of group II agonists were markedly attenuated by coadministration of a group II antagonist or a membrane-permeable cyclic AMP analog and were additive to those provided by an N-methyl-D-aspartate receptor antagonist or a selective group I mGluR antagonist. Administration of a group II mGluR agonist 30 min after lateral fluid percussion-induced brain injury in rats significantly improved subsequent behavioral recovery as compared with vehicle-treated controls. Together these studies indicate that group II mGluR agonists protect against traumatic neuronal injury by attenuating glutamate release and cAMP levels and suggest a potential role for these agents in the treatment of clinical neurotrauma.  (+info)

Endothelium-derived contracting factor in carotid artery of hypertensive Dahl rats. (5/549)

The present study is designed to investigate whether acetylcholine (ACh) elicits an endothelium-derived contracting factor (EDCF) and whether it contributes to decreased relaxant response induced by ACh in Dahl rats. Dahl salt-sensitive (DS) and -resistant (DR) rats were fed a 0.4% NaCl or an 8% NaCl diet for 4 weeks. High sodium intake significantly increased blood pressure in DS rats but not in DR rats. The carotid rings were suspended for isometric tension recording. ACh caused an endothelium-dependent contraction in carotid rings from hypertensive DS rats but not from normotensive Dahl rats. Atropine, indomethacin, SQ29548, or ONO-3708 (prostaglandin H(2) [PGH(2)]/thromboxane A(2) [TXA(2)] receptor antagonist) abolished ACh-induced contraction, and OKY-046 (inhibitor of TXA(2) synthetase) partially attenuated the contraction. High sodium intake significantly enhanced contraction evoked by U46619, a PGH(2)/TXA(2) receptor agonist, in both DS and DR rats. In contrast, ACh-induced relaxation was significantly depressed in the rings from hypertensive DS rats, and ONO-3708 partially improved the depressed relaxation. Administration of ONO-8809 (an orally active PGH(2)/TXA(2) receptor antagonist; 30 micrograms per body per day) for 4 weeks neither reduced blood pressure nor improved the depressed ACh-induced relaxation in hypertensive DS rats. These results suggest that ACh causes release of EDCF in carotid rings of hypertensive DS rats, which is likely to be PGH(2) and TXA(2). The EDCF contributed in part to the depressed ACh-induced relaxation.  (+info)

Fatty acid translocase/CD36 mediates the uptake of palmitate by type II pneumocytes. (6/549)

Type II pneumocytes, which synthesize, store, and secrete pulmonary surfactant, require exogenous fatty acids, in particular palmitic acid, for maximum surfactant synthesis. The uptake of palmitate by type II pneumocytes is thought to be protein mediated, but the protein involved has not been characterized. Here we show by RT-PCR and Northern blot analysis that rat type II pneumocytes express the mRNA for fatty acid translocase (FAT/CD36), a membrane-associated protein that is known to facilitate the uptake of fatty acids into adipocytes. The deduced amino acid sequence from rat type II pneumocytes reveals 98% identity to the FAT/CD36 sequence obtained from rat adipocytes. The uptake of palmitate by type II pneumocytes follows Michaelis-Menten kinetics (Michaelis-Menten constant = 11.9 +/- 1.8 nM; maximum velocity = 62.7 +/- 5.8 pmol. min(-1). 5 x 10(5) pneumocytes(-1)) and decreases reversibly under conditions of ATP depletion to 35% of control uptake. Incubation of cells at 0 degrees C inhibited the uptake of palmitate almost completely, whereas depletion of potassium was without effect. Preincubation of the cells with bromobimane or phloretin decreases the uptake of palmitate significantly as does preincubation with sulfo-N-succinimidyl oleate, the specific inhibitor of FAT/CD36 (C. M. Harmon, P. Luce, A. H. Beth, and N. A. Abumrad. J. Membr. Biol. 121: 261-268, 1991). From these data, we conclude that FAT/CD36 is expressed in type II pneumocytes and mediates the uptake of palmitate in a saturable and energy-dependent manner. The data suggest that the uptake process is independent of the formation of coated pits and endocytotic vesicles.  (+info)

Hyperforin, a major antidepressant constituent of St. John's Wort, inhibits serotonin uptake by elevating free intracellular Na+1. (7/549)

Extracts of Hypericum perforatum (St. John's Wort) are widely used for the treatment of depressive disorders and are unspecific inhibitors of the neuronal uptake of several neurotransmitters. Previous studies have shown that hyperforin represents the reuptake inhibiting constituent. To characterize the mechanism of serotonin reuptake inhibition, kinetic analyses in synaptosomes of mouse brain were performed. Michaelis-Menten kinetics revealed that hyperforin (2 microM) induces a decrease in V(max) by more than 50% while only slightly decreasing K(m), indicating mainly noncompetitive inhibition. By contrast, citalopram (1 nM) leads to an elevation of K(m) without changing V(max). Monensin, a Na(+)/H(+) exchanger, showed similar properties as hyperforin (decrease of V(max) without changing K(m)). Compared with classical antidepressants, such as selective serotonin reuptake inhibitors and tricyclic antidepressants, hyperforin is only a weak inhibitor of [(3)H]paroxetine binding relative to its effects on serotonin uptake. As monensin decreases serotonin uptake by increasing Na(+)/H(+) exchange, we compared the effects of hyperforin and monensin on the free intracellular sodium concentration ([Na(+)](i)) in platelets by measuring 1,3-benzenedicarboxylic acid, 4,4'-[1,4,10-trioxa-7, 13-diazacyclopentadecan-7,13-diylbis(5-methoxy-6, 2-benzofurandiyl)]bis-, tetraammonium salt (SBFI/AM) fluorescence. Both drugs elevated [Na(+)](i) over basal levels, with a maximal [Na(+)](i) of 69 +/- 16.1 mM (50 microM hyperforin) and 140 +/- 9.1 mM (10 microM monensin). Citalopram at concentrations relevant for [(3)H]serotonin uptake inhibition had no effect on [Na(+)](i). Although the mode of action of hyperforin seems to be associated with elevated [Na(+)](i) similar to those levels found with monensin, the molecular mechanism might be different, as even at high concentrations, hyperforin does not elevate free intracellular sodium concentration ([Na(+)](i)) up to the extracellular level, as monensin does. Hyperforin represents the first substance with a known preclinical antidepressant profile that inhibits serotonin uptake by elevating [Na(+)](i).  (+info)

Here we describe the properties of CP-154,526, a potent and selective nonpeptide antagonist of corticotropin (ACTH) releasing factor (CRF) receptors. CP-154,526 binds with high affinity to CRF receptors (Ki , 10 nM) and blocks CRF-stimulated adenylate cyclase activity in membranes prepared from rat cortex and pituitary. Systemically administered CP-154,526 antagonizes the stimulatory effects of exogenous CRF on plasma ACTH, locus coeruleus neuronal firing and startle response amplitude. Potential anxiolytic activity of CP-154,526 was revealed in a fearpotentiated startle paradigm. These data are presented in the context of clinical findings, which suggest that CRF is hypersecreted in certain pathological states. We propose that a CRF antagonist such as CP-154,526 could affirm the role of CRF in certain psychiatric diseases and may be of significant value in the treatment of these disorders.. ...

Pinene is another distinctive terpene and there are actually two different strains that are used.. Your CBD might contain either alpha-pinene or beta-pinene, although they are both derived from pine trees and the pleasant smell is unmistakable when it hits your nostrils.. The main benefits attached to both the alpha-pinene and beta-pinene is their anti-inflammatory properties. Pinene is also considered useful for people with respiratory issues such as asthma.. Love lavender?. The smell of lavender is very distinctive and is an aroma associated with calmness and relaxation.. Linalool is the terpene that is found in lavender and CBD products and other herbs enriched by it also include coriander, mint, and cinnamon. This particular compound is often used when the purpose is to reduce inflammation, help you to contend with arthritis, and help reduce the impact of seizures.. It might be suggested to you that if you use other herbs that contain linalool in addition to your chosen CBD product it could ...

Group II metabotropic glutamate receptors (mGluR2 and mGluR3, encoded by GRM2 and GRM3) are implicated in hippocampal function and cognition, and in the pathophysiology and treatment of schizophrenia and other psychiatric disorders. However, pharmacological and behavioral studies with group II mGluR agonists and antagonists have produced complex results. Here, we studied hippocampus-dependent memory in GRM2/3 double knockout (GRM2/3-/-) mice in an iterative sequence of experiments. We found that they were impaired on appetitively motivated spatial reference and working memory tasks, and on a spatial novelty preference task that relies on animals exploratory drive, but were unimpaired on aversively motivated spatial memory paradigms. GRM2/3-/-mice also performed normally on an appetitively motivated, non-spatial, visual discrimination task. These results likely reflect an interaction between GRM2/3 genotype and the arousal-inducing properties of the experimental paradigm. The deficit seen on appetitive

The graphs show the effects of ketamine 30 mg/kg (KET), LY379268 3 mg/kg (LY), the vehicle (VEH) and co-administration of ketamine 30 mg/kg + LY379268 3 mg/kg (KET/LY) on the absolute (a) and relative (b) power spectra. For better graphical presentation, data are expressed per 1 Hz as the percent change of their corresponding baseline with ±SEM × 100 / mean power of the corresponding baseline. Thus, all baselines are represented by the X axis (the zero line). Significant differences of mean power within the whole spectral bands of each treatment compared to the vehicle are shown in the upper part of the figure (ANCOVA). The direction of change is indicated by arrows. The ketamine-induced increase of low-gammaand the decrease in delta and theta powerwere reversed by LY379268. The decrease in beta andhighpower in LY379268was also observed in the ketamine + LY379268 treated animals. *** indicates p b 0.001 for ketamine 30 mg/kg vs the vehicle. ‡‡‡
