Abstract
Pain is the most frequent symptom of disease. In treating pain, a lower incidence of adverse effects is found for paracetamol versus other non-steroidal anti-inflammatory drugs. Nevertheless, paracetamol can trigger side effects when taken regularly. Combined therapy is a common way of lowering the dose of a drug and thus of reducing adverse reactions. Since β-caryophyllene oxide (a natural bicyclic sesquiterpene) is known to produce an analgesic effect, this study aimed to determine the anti-nociceptive and gastroprotective activity of administering the combination of paracetamol plus β-caryophyllene oxide to CD1 mice. Anti-nociception was evaluated with the formalin model and gastroprotection with the model of ethanol-induced gastric lesions. According to the isobolographic analysis, the anti-nociceptive interaction of paracetamol and β-caryophyllene oxide was synergistic. Various pain-related pathways were explored for their possible participation in the mechanism of action of the anti-nociceptive effect of β-caryophyllene oxide, finding that NO, opioid receptors, serotonin receptors, and K+ATP channels are not involved. The combined treatment showed gastroprotective activity against ethanol-induced gastric damage. Hence, the synergistic anti-nociceptive effect of combining paracetamol with β-caryophyllene oxide could be advantageous for the management of inflammatory pain, and the gastroprotective activity should help to protect against the adverse effects of chronic use.

Abstract
CONTEXT The gastroprotective effect of Heliotropium indicum L. (Boraginaceae), a plant traditionally used in Mexico to treat gastric ulcers, has been previously reported. However, no active compound was identified. OBJECTIVE The current contribution aimed to isolate, through a bioassay-guided study, at least one compound from H. indicum with considerable gastroprotective activity, examine its effect on ethanol-induced gastric lesions in mice, and explore possible mechanisms of action. MATERIALS AND METHODS Three extracts (hexane, dichloromethane, and methanol) were obtained from H. indicum leaves. Their 30 and 100 mg/kg doses were assessed on ethanol-induced gastric lesions in male CD1 mice. Since the dichloromethane extract was the most active, successive chromatographies were carried out leading to the identification of the most active compound. This compound (at 3-100 mg/kg) was compared to carbenoxolone (at 10-100 mg/kg) in biological evaluations in mice. Pre-treatments with indomethacin (10 mg/kg, s.c.), L-NAME (70 mg/kg, i.p.), and NEM (10 mg/kg, s.c.) were performed independently to determine the participation of prostaglandins, nitric oxide, and/or sulfhydryl groups, respectively, in the mechanism of action of the compound. RESULTS (E)-Ethyl-12-cyclohexyl-4,5-dihydroxydodec-2-enoate, a compound isolated from H. indicum, afforded dose-dependent gastroprotective activity. The maximum effect was observed at 100 mg/kg (90.13 ± 3.08%), with an ED50 of 5.92 ± 2.48 mg/kg. Gastroprotection was not modified by pre-treatment with indomethacin, L-NAME, or NEM. CONCLUSIONS (E)-Ethyl-12-cyclohexyl-4,5-dihydroxydodec-2-enoate, isolated from H. indicum, was found to produce a substantial gastroprotective effect. Prostaglandins, nitric oxide, and non-protein sulfhydryl groups are not involved in its mechanism of action.

Abstract
The main hydrometeorological, microbiological and physico-chemical characteristics of the Nervión river were monitored during a year, including 10 antibiotics and the presence of bacteria resistant to these antibiotics among faecal coliforms (FC) and total aerobic bacteria at 22 °C (TAB22). The characteristics of the river water were variable without a clear seasonal component, strongly influenced by rainfall, with a good quality for drinking water production throughout the year according to the physico-chemical parameters. The antibiotic resistant bacteria isolated from the water of the Nervión river were especially resistant to β-lactams and macrolide antibiotics, highlighting the absence of resistance to derivatives of tetracyclines among strains of TAB22. A third of the isolated strains were multi-resistant to antibiotics with a seasonal component in its presence, with multi-resistant FC more abundant during summer and multi-resistant TAB22 more abundant during winter. The presence of antibiotics in the waters of the Nervión river was not very significant, with total absence of β-lactams, minocycline and ciprofloxacin. Erythromycin and clarithromycin can be considered ubiquitous with mean concentrations of 2.5 ± 2.3 ngL-1 and 5.7 ± 4.6 ngL-1 respectively, and the presence of sulfamethoxazole and trimethoprim was also noticeable with maximum concentrations of 78.3 ngL-1 for sulfamethoxazole. Dilution due to the increase of rainfall was observed for several analysed antibiotics, but without significant seasonal differences.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are very commonly used, but their adverse effects warrant investigating new therapeutic alternatives. Polyalthic acid, a labdane-type diterpenoid, is known to produce gastroprotection, tracheal smooth muscle relaxation, and antitumoral, antiparasitic and antibacterial activity. This study aimed to evaluate the antinociceptive, antiallodynic, antihyperalgesic and anti-inflammatory effect of polyalthic acid on rats. Moreover, the effectiveness of treating hyperalgesia with a combination of polyalthic acid and naproxen was analyzed, as well as the type of drug-drug interaction involved. Nociception was examined by injecting 1% formalin into the right hind paw and thermal hyperalgesia and inflammation by injecting a 1% carrageenan solution into the left hind paw of rats. Allodynia was assessed on an L5/L6 spinal nerve ligation model. Polyalthic acid generated significant antinociceptive (56-320 mg/kg), antiallodynic (100-562 mg/kg), and antihyperalgesic and anti-inflammatory (10-178 mg/kg) effects. Antinociception mechanisms were explored by pretreating the rats with naltrexone, ODQ and methiothepin, finding the effect blocked by the former two compounds, which indicates the participation of opioid receptors and guanylate cyclase. An isobolographic analysis suggests synergism between polyalthic acid and naproxen in the combined treatment of hyperalgesia.

Abstract
Although nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the main types of drugs used to treat pain, they have several adverse effects, and such effects can be reduced by combining two analgesic drugs. The aim of this study was to evaluate the nociceptive activity of methyleugenol combined with either diclofenac or ketorolac, and determine certain parameters of pharmacokinetics. For the isobolographic analysis, the experimental effective dose 30 (ED30) was calculated for the drugs applied individually. With these effective doses, the peak plasma concentration (Cmax) was found and the other parameters of pharmacokinetics were established. Methyleugenol plus diclofenac and methyleugenol plus ketorolac decreased licking behavior in a dose-dependent manner in phase II, with an efficacy of 32.9 ± 9.3 and 39.8 ± 9.6%, respectively. According to the isobolographic analysis, the experimental and theoretical ED30 values were similar for methyleugenol plus diclofenac, suggesting an additive effect, but significantly different for methyleugenol plus ketorolac (3.6 ± 0.5 vs. 7.7 ± 0.6 mg/kg, respectively), indicating a probable synergistic interaction. Regarding pharmacokinetics, the only parameter showing a significant difference was Cmax for the methyleugenol plus diclofenac combination. Even with this difference, the combinations studied may be advantageous for treating inflammatory pain, especially for the combination methyleugenol plus ketorolac.

Abstract
The persistent motility of individual constituents in microbial suspensions represents a prime example of the so-called active matter systems. Cells consume energy, exert forces and move, overall releasing the constraints of equilibrium statistical mechanics of passive elements and allowing for complex spatio-temporal patterns to emerge. Moreover, when subject to physico-chemical stimuli their collective behaviour often drives large-scale instabilities of a hydrodynamic nature, with implications for biomixing in natural environments and incipient industrial applications. In turn, our ability to exert external control of these driving stimuli could be used to govern the emerging patterns. Light, being easily manipulable and, at the same time, an important stimulus for a wide variety of microorganisms, is particularly well suited to this end. In this paper, we will discuss the current state, developments and some of the emerging advances in the fundamentals and applications of light-induced bioconvection with a focus on recent experimental realizations and modelling efforts. This article is part of the theme issue 'Stokes at 200 (part 2)'.

Abstract
Diatoms are one of the most abundant, diverse and ecologically relevant phytoplanktonic group, contributing enormously to global biogeochemical processes like the carbon and silica cycles. This large success has been partly attributed to the mechanical and optical properties of the silica shell (the frustule) that envelops their body. But since they lack motility it is difficult to conceive how they cope with the fast-fluctuating environment they live in and where distributions of resources are very heterogeneous and dynamical. This pinpoints an important but yet poorly understood feature of diatoms physiology: buoyancy regulation that helps them controlling their sinking speed and position in the water column. While buoyancy regulation by light and nutrients availability has been well studied, the effect of hydromechanical stress via fluid shear has been rather overlooked when considering diatoms dynamics. Here, we aim to start filling this gap by first presenting direct experimental evidences for buoyancy control in response to hydro-mechanical stress and then review recent theoretical models where simple couplings between local shear and buoyancy control always result in heterogeneous cell distributions, specific accumulation regions within complex flows and increased sedimentation times to the depths, features of direct ecological relevance. We conclude by suggesting future experiments aiming to unveil such coupling and therefore gain better understanding on the fate of these fascinating microorganisms in their natural habitat. This article is part of the theme issue 'Stokes at 200 (part 2)'.

Abstract
Peptic ulcers are currently treated with various drugs, all having serious side effects. The aim of this study was to evaluate the gastroprotective activity of calein D (from Calea urticifolia), a sesquiterpene lactone with a germacrane skeleton. Gastric lesions were induced in mice by administering ethanol (0.2 mL) after oral treatment with calein D at 3, 10 and 30 mg/kg, resulting in 13.15 ± 3.44%, 77.65 ± 7.38% and 95.76 ± 2.18% gastroprotection, respectively, to be compared with that of the control group. The effect found for 30 mg/kg of calein D was not reversed by pretreatment with NG-nitro-l-arginine methyl ester (l-NAME, 70 mg/kg, ip), indomethacin (10 mg/kg, sc) or N-ethylmaleimide (NEM, 10 mg/kg, sc). Hence, the mechanism of action of calein D does not involve NO, prostaglandins or sulfhydryl compounds. Calein D was more potent than carbenoxolone, the reference drug. The findings for the latter are in agreement with previous reports.

Abstract
Hit, Lead & Candidate Discovery The gastroprotective effect of calealactone B, isolated from Calea urticifolia was assessed in an ethanol-induced model of gastric lesioning. The possible involvement of prostaglandins, nitric oxide (NO) and sulfhydryl groups in the mechanism of action of calealactone B was also assessed. Calealactone B inhibited ethanol-induced gastric injuries with a maximal effect (95.3 ± 2.6%) at 30 mg kg-1 . A similar value was obtained at 10 mg kg-1 (83.5 ± 7.7%). Meanwhile, the reference anti-ulcer drug, carbenoxolone, an 11β-hydroxysteroid dehydrogenase (11β-HSD) inhibitor administered at 30 mg kg-1 showed 63.5 ± 9.4% gastroprotection. Hence, calealactone B was more potent than carbenoxolone. Pretreatment with indomethacin, L-NAME or NEM did not reverse the effects of calealactone B, indicating that prostaglandins, NO and sulfhydryl compounds do not participate in its mechanism of action.

Abstract
(‒)-Encecanescin (1) has been isolated from the leaves of Eupatorium aschembornianum. Two conformers are present in the crystal structure as a result of molecular disorder. The structure of 1 was established by 1H- and 13C-NMR spectroscopy in CDCl3 solution using 2D NMR techniques (gHSQC, gHMBC and NOESY). A Monte Carlo random search using molecular mechanics followed by the geometry optimization of each minimum energy structure using density functional theory (DFT) calculations at the B3LYP/6–31G* level and a Boltzmann analysis of the total energies generated accurate molecular models describing the conformational behavior of 1. The three most stable conformers 2–4 of compound 1 were reoptimized at the B3LYP/6-311++G(d,p) level of theory using CHCl3 as a solvent. Correlations between the experimental 1H- and 13C-NMR chemical shifts (δexp) have been found, and the GIAO/B3LYP/6-311++G(d,p) calculated magnetic isotropic shielding tensors (σcalc) for conformers 2 and 3, δexp = a + b σcalc, are reported. A good linear relationship between the experimental and calculated NMR data has been obtained for protons and carbon atoms.

Abstract
Peperomia pellucida is a plant used in traditional medicine to treat gastric ulcers. Although this gastroprotective activity was reported, the active compounds have not been identified. Therefore, the aim herein was to identify the most active compound in the gastroprotective activity of P. pellucida using an ethanol-induced gastric ulcer experimental rat model. A gastroprotective effect was observed when the hexane and dichloromethane extracts were tested, with the higher effect being obtained with the dichloromethane extract (82.3 ± 5.6%) at 100 mg/kg. Dillapiole was identified as the most active compound in this extract. Although there have been previous reports on dillapiole, this is the first on its gastroprotective activity. Rats treated with this compound at 3, 10, 30 and 100 mg/kg showed 23.1, 56.1, 73.2 and 85.5% gastroprotection, respectively. The effect elicited by dillapiole at 100 mg/kg was not attenuated by pretreatment with indomethacin (10 mg/kg, s.c.), a prostaglandin synthesis blocker, NG-nitro-l-arginine methyl ester (70 mg/kg, i.p.), a nitric oxide (NO) synthase inhibitor, or N-ethylmaleimide (10 mg/kg, s.c.), a blocker of sulfhydryl groups. This suggests that the gastroprotective mechanism of action of dillapiole does not involve prostaglandins, NO or sulfhydryl groups.

Abstract
The present study aimed to evaluate the antinociceptive activity (in inflammatory and neuropathic pain models) and gastroprotective effect of the 3,5-diprenyl-4-hydroxyacetophenone (HYDP), isolated from Ageratina pichinchensis. The gastroprotective activity of this plant was previously reported by our workgroup, finding encesanescin to be one active compound. The present results show that HYDP reduced nociception in a dose-dependent manner in carrageenan and L5/L6 spinal nerve ligation, with efficacies of 72.6 and 57.1%, respectively, at doses of 100 and 562 mg/kg. HYDP also showed gastroprotective activity in the model of ethanol-induced gastric lesion, with a 75.59% maximum inhibition of ulcers at a dose of 100mg/kg. This gastroprotective effect was attenuated by N(G)-nitro-L-arginine methyl ester, indomethacin and N-ethylmaleimide, indicating that NO, prostaglandins and sulfhydryl groups are involved in the mechanisms of action. This is the first evidence, to our knowledge, of the antinociceptive and gastroprotective activities of HYDP.

Abstract
Hyptis suaveolens is a medicinal plant that is, according to traditional medicine, considered useful in the treatment of gastric ulcers. Although its gastroprotective activity was reported, the active compounds have not been identified. Therefore, the aim of the present study was to identify at least one active compound potentially responsible for the gastroprotective activity of H. suaveolens by using a bioassay guided study with an ethanol-induced gastric ulcer experimental model in rats. The results show that the hexane extract had protective activity (close to 70% when using doses between 10 and 100 mg/kg), and that the compound suaveolol, isolated from this extract, was one of the active gastroprotective agents. This is the first report about the gastroprotective activity of suaveolol. Rats treated with this compound at 3, 10, 30 and 100 mg/kg showed 12.6, 21.3, 39.6 and 70.2% gastroprotection respectively. The effect elicited by suaveolol (at 100 mg/kg) was attenuated by pretreatment with either NG-nitro-L-arginine methyl ester (70 mg/kg, i.p.), a nitric oxide (NO) synthase inhibitor, indomethacin (10 mg/kg, s.c.), a blocker of prostaglandin synthesis, or N-ethylmaleimide (10 mg/kg, s.c.), a blocker of sulfhydryl groups. This suggests that the gastroprotective mechanism of action of this compound involves NO, prostaglandins and sulfhydryl groups.

Abstract
Tithonia diversifolia is a medicinal plant from the Municipality of Suchiapa, Chiapas, Mexico, that according to local folk medicine is considered useful in the treatment of gastric ulcers. The aim of the present study was to investigate the gastroprotective activity of T. diversifolia by using an ethanol-induced gastric ulcer experimental model in male Wistar rats. The results showed that T. diversifolia had gastroprotective activity, and that the dichloromethane extract had the highest protective activity (close to 90% when using doses between 10 to 100 mg/kg), and that further the compound tagitinin C isolated from this extract was the main active gastroprotective agent. Rats treated with tagitinin C suspended in Tween 80 at 1, 3, 10 and 30 mg/kg showed 37.7, 70.1, 100, and 100% gastroprotection, respectively. The effect elicited by tagitinin C (30 mg/kg) was not attenuated by pretreatment with either NG-nitro-L-arginine methyl ester (70 mg/kg, i.p.), a nitric oxide (NO) synthase inhibitor, N-ethylmaleimide (10 mg/kg, s.c.), a blocker of sulfhydryl groups, or indomethacin (10 mg/kg, s.c.), a blocker of prostaglandin synthesis, which suggests that the gastroprotective mechanism of action of this sesquiterpene lactone does not involve NO, sulfhydryl groups or prostaglandins.

Abstract
Given the high prevalence of the hyponutrition state among haemodialysis patients and knowing that this implies an increase in the rates of infection, hospitalisation and hospital stay, which translates into an increase in global morbid-mortality, the Spanish Society of Nephrology (SEN) and the Spanish Society of Parenteral and Enteral Nutrition (SENPE) have reached a consensus on the indications, contraindications, and limitations of Intra-Dialysis Parenteral Nutrition (IDPN.) This consensus considers IDPN as a valid alternative to other types of nutritional support when these show their lack of efficacy. The bases are set regarding the timing of nutritional intervention with IDPN, its ideal composition, the time of administration, its controls, follow-up schedules, and the time at which the nutritional support has to be discontinued.

Abstract
This work aimed to study the effect of Cuachalalate methanol extract (CME) on the anti-inflammatory activity and pharmacokinetics of diclofenac sodium, a frequently prescribed non-steroidal antiinflammatory drug (NSAID). The gastroprotective effect of CME on the gastric injury induced by diclofenac was studied in rats. CME showed a gastroprotective effect of 15.7% at 1 mg kg−1 and 72.5% at dose of 300 mg kg−1. Omeprazole, used as anti-ulcer reference drug, showed gastroprotective effects of 50–89.7% at doses tested (1–30 mg kg−1). The value of the 50% effective dose for the anti-inflammatory effect of diclofenac sodium (ED50 = 1.14 ± 0.23 mg kg−1) using carrageenaninduced rat paw oedema model, was not modified by the concomitant administration of 30 or 100 mg kg−1 of CME. The effect of CME (30, 100 and 300 mg kg−1, p.o.) on the pharmacokinetics of diclofenac sodium was studied. It was observed that the simultaneous administration of diclofenac sodium and 300 mg kg−1 of CME decreased significantly the values of Cmax (7.08 ± 1.42 μg mL−1) and AUC (12.67 ± 2.97 μg h mL−1), but not the value of tmax (0.13 (0.1–0.25) h) obtained with the administration of diclofenac alone. The simultaneous administration of 30 or 100 mg kg−1 of CME did not modify the pharmacokinetic parameters of diclofenac. The experimental findings in rats suggest that CME at doses lower than 100 mg kg−1 protects the gastric mucosa from the damage induced by diclofenac sodium without altering either the anti-inflammatory activity or the pharmacokinetics of this NSAID.

Abstract
Croton reflexifolius H. B. K (Euphorbiaceae) is a very common medicinal plant in the Huastecan region of Mexico that, according to local folk medicine, is considered useful in the treatment of gastritis and gastric ulcer. We have aimed to test the validity of this practice by using the experimental model of an ethanol-induced gastric ulcer in male Wistar rats. The results showed that C. reflexifolius had gastroprotector activity, that the hexane extract had the highest protective activity (64.38+/-7.72%), and that polyalthic acid isolated from this extract was the main active gastroprotector agent. Rats treated orally with polyalthic acid showed a gastroprotective effect similar to that elicited by carbenoxolone. As with carbenoxolone, the effect elicited by polyalthic acid was attenuated by pretreatment with either N(G)-nitro-L-arginine methyl ester (70 mgkg(-1), i.p.), a nitric oxide (NO) synthase inhibitor, or N-ethylmaleimide (10 mgkg(-1), s.c.), a blocker of sulfhydryl groups. This suggested that the gastroprotective mechanism of this diterpenoid involved the participation of both NO and endogenous sulfhydryl groups. Contrary to carbenoxolone, the gastroprotective effect of polyalthic acid was not affected by the inhibition of prostaglandin synthesis with indometacin (10 mgkg(-1), s. c.). In conclusion, Croton reflexifolius contains compounds with gastroprotector activity. Polyalthic acid, which was isolated from this plant, was the main compound with gastroprotector activity, having effectiveness similar to that found with the use of carbenoxolone. Whereas NO and sulfhydryl groups were involved in the mechanisms of gastroprotective action of polyalthic acid, prostaglandins were not.

Abstract
In this investigation the gastroprotective activity of stigmasterol and β-sitosterol was evaluated. Gastric mucosal damage was induced in rats by intragastric ethanol (1 mL/rat). Rats treated orally with stigmasterol suspended in Tween 80 at 10, 30, 100 and 300 mg kg−1 showed 26.2, 39.6, 58.3 and 70.7% gastroprotection, respectively. β-Sitosterol at 10, 30,100 and 300 mg kg−1 showed 21.6, 42.5, 48.5 and 71.2% gastroprotection, correspondingly. The gastroprotection observed at 30 mg kg−1 for stigmasterol and β-sitosterol was attenuated in rats pretreated with indomethacin, (10 mg kg−1, s. c.), NG-nitro-L-arginine methyl ester (L-NAME, 70 mg kg−1, i. p.) and capsaicin (125 mg kg−1, s. c), suggesting that the gastroprotective mechanism of these sterols involves, at least in part, the participation of prostaglandins, nitric oxide (NO) and capsaicin-sensitive sensory neurons (CPSN). The gastroprotection of β-sitosterol was also attenuated by the pretreatment with N-ethylmaleimide (NEM, 10 mg kg−1, s. c.) indicating that endogenous sulfrydryls may be involved in the gastrorpotection of this compound. Carbenoxolone was used as a gastroprotective model drug and showed a dose-dependent gastroprotective effect (25.7, 33.6 and 88.3% of gastroprotection, at 3, 10 and 30 mg kg−1, respectively). The partial participation of PGs, sulfhydryls and NO was observed in the gastroprotective mechanism of carbenoxolone.

Abstract
We investigated the mechanisms of action of Gnaphalium liebmannii which is used as a folk medicine in México for treating various respiratory diseases such as gripe, fever, asthma, cough, cold, bronchitis, expectorating, and bronchial affections. The tension changes of guinea pig tracheal segments were isometrically recorder on a polygraph. Hexane extract of Gnaphalium liebmannii was the most active relaxant extract (IC(30)=54.23+/-19.79 microg/mL with 99.5+/-3.2 % of relaxation), followed by dichloromethane extract (IC(30)=120.22+/-5.27 microg/mL) and methanol extract (IC(30)=190.25+/-30.02 microg/mL). Hexane extract produced a parallel rightward shift of the concentration-response curve of carbachol in a competitive manner (pA(2)=-2.4), but did not modify the concentration-response curves for histamine. The relaxant effect of hexane extract of Gnaphalium liebmannii was unaffected by the presence of propranolol (3x10(-6)M) or glibenclamide (10 microM). However hexane extract produced a leftward shifts of the concentration-response curve of forskolin (10(-8) to 10(-3)M), nitroprusside (10(-10) to 10(-6)M), isoproterenol (3x10(-10) to 3x10(-5)M) and aminophylline (10(-11) to 10(-2)M). The above results suggest that Gnaphalium liebmannii induce relaxation of the tracheal muscle, probably via phosphodiesterase inhibition. The bronchodilator effect of Gnaphalium liebmannii might explain in part their traditional use as anti-asthmatic remedy.

Abstract
This investigation evaluated the gastroprotective activity of Astragaloside IV, a cycloartane-type triterpene glycoside isolated from Astragalus zahlbruckneri. Gastric mucosal damage was induced in rats by intragastric ethanol (1 mL/rat). Rats treated orally with Astragaloside IV suspended in Tween 80 at 3, 10 and 30 mg kg(-1), showed 15, 37 and 52% gastroprotection, respectively. The gastroprotection observed at 30 mg kg(-1) for this compound was attenuated in rats pretreated with N(G)-nitro-L arginine methyl ester (70 mg kg(-1), i.p), a nitric oxide (NO)-synthase inhibitor, suggesting that the gastroprotective mechanism of this glycoside involves, at least in part, the participation of NO. The gastroprotective effect of Astragaloside IV was not affected by the inhibition of prostaglandin synthesis with indometacin (10 mg kg(-1), s.c.) nor by the block of endogenous sulfhydryls with N-ethylmaleimide (NEM, 10 mg kg(-1), s.c.). Carbenoxolone was used as a gastroprotective model drug and showed a dose-dependent gastroprotective effect (25, 43 and 88% of gastroprotection, at 3, 10 and 30 mg kg(-1), respectively). The partial participation of prostaglandins, sulfhydryls and NO was observed in the gastroprotective mechanism of carbenoxolone.

Abstract
In Spain and in each of its autonomous communities, the dialysis treatment of chronic renal disease stage 5 is totally covered by public health. Peritoneal dialysis, in any of its modalities, is established as the preferred home dialysis technique and is chosen by high percentage of patients as their choice in dialysis treatment. The Spanish Society of Nephrology has promoted a project of creation of performance guides in the field of peritoneal dialysis, entrusting a work group composed of members of the Spanish Society of Nephrology a with the development of these guides. The information offered is based on levels of evidence, opinion and clinical experience of the most relevant publications of the topic. In these guides, after defining the concept of << peritoneal dialysis>>, the obligations and responsibilities of the sanitation team of the peritoneal dialysis unit are determined, and protocols and performance procedures that try to include all the aspects that concern the patient with chronic renal disease in substitute treatment with this technique are developed. They propose prescription objectives based on available clinical evidence and, lacking this, on the consensus of the experts' opinions. The final aim is to improve the care and quality of the of the patient in peritoneal dialysis, optimizing in this way the survival of the patient and of the technique. In Spain, as in other neighbouring countries, peritoneal dialysis has an incidence and prevalence that is much lower than that of hemodialysis, ranging in the last evaluation by the Spanish Society of Nephrology between 5 and 24% in the different autonomous communities. The great majority of peritoneal dialysis units form part of the public network of the Spanish state, with special representation as a Satellite Unit or Concerted Center related to the public hospital of reference, on which it must depend.

Abstract
Quality of vascular access (VA) has a remarkable influence in hemodialysis patients outcomes. Dysfunction of VA represents a capital cause of morbi-mortality of these patients as well an increase in economical. Spanish Society of Neprhology, aware of the problem, has decided to carry out a revision of the issue with the aim of providing help in comprehensión and treatment related with VA problems, and achieving an homogenization of practices in three mayor aspects: to increase arteriovenous fistula utilization as first vascular access, to increment vascular access monitoring practice and rationalise central catheters use. We present a consensus document elaborated by a multidisciplinar group composed by nephrologists, vascular surgeons, interventional radiologysts, infectious diseases specialists and nephrological nurses. Along six chapters that cover patient education, creation of VA, care, monitoring, complications and central catheters, we present the state of the art and propose guidelines for the best practice, according different evidence based degrees, with the intention to provide help at the professionals in order to make aproppiate decissions. Several quality standars are also included.

Abstract
Valerian is the common name given to the crude drug consisting of the underground organs of the species Valeriana. Valeriana edulis ssp. procera Meyer is the Mexican valerian. The aim of the present work was to elucidate the neuropharmacological profile of a hydroalcohol extract of Valeriana edulis roots at doses of 100, 300 and 1000 mg/kg in several experimental models. A dose-dependent anticonvulsant and anxiolytic-like effect of V. edulis was demonstrated. In addition, the extract decreased rotarod performance and traction force and prolonged the pentobarbital-induced sleeping time at high doses. Concomitant administration of valerian extract and pentobarbital showed a synergistic effect on motor coordination and traction force in mice. The anxiolytic-like effect of V. edulis was compared with diazepam and with diphenhydramine and doxylamine, the latter in order to consider the H(1)-antihistamine effect as another possibility to explain, at least in part, the central nervous system depressant effect of valerian. These results also underlie the medical and industrial use of this species and allowed the conclusion that the extract of V. edulis has central nervous depressant properties similar to, but with some differences to V. of ficinalis, a very well known species.

Abstract
UNLABELLED Sclerosing encapsulating peritonitis secondary to peritoneal dialysis has been associated to acetate-containing dialysis fluids, hypertonic glucose and disinfectants. Physiopathologic mechanisms of fibrotic proliferation that implicate those agents are not totally explained. With an experimental approach using cultured peritoneal fibroblasts, we have studied intracellular pH changes and Na+/H+ antiporter activity under cells perfusion with peritoneal dialysis liquids containing acetate, lactate, hypertonic glucose and interleukin-1. All experiments were performed at extracellular pH 7.4 and physiologic HCO3/CO2 concentration. RESULTS 35 mM acetate produced a huge intracellular acidosis (ipH = 6.80 +/- 0.08). Lactate effect was less important (6.95 +/- 0.07), with a slow ipH recovery in about 30 min in both cases. IL-1, 10(-6) M also reduced ipH to 7.10 +/- 0.03. Acidosis was linked to Ca2+ outflow via Ca/H exchange and was blocked with Cd 20 nM. Extracellular Na = 0 and amiloride totally inhibited ipH recovery after acetate, lactate, or interleukin-induced acidosis. Hypertonic glucose perfusion increased ipH (7.31 +/- 0.06) for 5-7 min. This increase was also inhibited by amiloride or extracellular Na absence. Na+/H+ exchanger activity increased to 58%, and kept activated after ipH recovery. In conclusion, acetate, hypertonic glucose and IL-1 showed the common effect of stimulating the sodium-proton exchanger by different mechanisms, giving a possibility of potentiation. Activated Na+/H+ exchanger may act as a signal-transduction increasing fibroblast proliferation and explaining the cellular mechanism of sclerosing peritonitis.

Abstract
In this investigation three bioactive compounds, responsible for the gastroprotective property of Amphipterygium adstringens, were purified from an active dichloromethane fraction. These compounds were 3alpha-hydroxymasticadienonic acid, beta-sitosterol and 3- epi-oleanolic acid. The latter was the most active compound (88.8 % of gastroprotection) followed by 3alpha-hydroxymasticadienoic acid and beta-sitosterol (69.8 and 42.5 % of gastroprotection, respectively). Carbenoxolone was used as positive control and it showed 88.4 % of gastroprotection. Masticadienonic acid was also isolated from the active fraction, but it was unable to inhibit the ethanol-induced gastric lesions. The gastroprotection of the methanol extract was completely inhibited by the pretreatment with l-NAME and attenuated by pretreatment with indomethacin and N-ethylmaleimide. These results suggest that endogenous nitric oxide plays an important role in the gastroprotection of A. adstringens methanol extract on ethanol-induced gastric mucosal lesions and that there is partial participation by prostaglandins and endogenous sulfhydryls. The effect of 3alpha-hydroxymasticadienonic acid was attenuated only by pretreatment with N-ethylmaleimide, indicating that endogenous sulfhydryls (thiols) participate in its gastroprotective mechanism. Capsaicin-sensitive afferent neurons do not participate in the gastroprotection of either the methanol extract or 3alpha-hydroxymasticadienoic acid.

Abstract
The crude ethanol extract from the leaves of Zanthoxylum liebmannianum exhibited inhibitory effect on the reproduction of trophozoites of Entamoeba histolytica (IC(50)=3.48 microg/ml) and Giardia lamblia (IC(50)=58.00 microg/ml). From this extract, asarinin, hyperin, beta-sitosterol, and beta-sitosterol glucoside were isolated. Among them, asarinin was the most active with IC(50) values of 19.86 microg/ml for E. histolytica and 35.45 microg/ml for G. lamblia. The remaining compounds showed moderate activity against both parasites.

Abstract
Levansucrase (EC 2.4.1.10) was identified as a constitutive exoenzyme in 14 Gluconacetobacter diazotrophicus strains recovered from different host plants in diverse geographical regions. The enzyme, consisting of a single 60-kDa polypeptide, hydrolysed sucrose to synthesise oligofructans and levan. Sugar-cane-associated strains of the most abundant genotype (electrophoretic type 1) showed maximal values of levansucrase production. These values were three-fold higher than those of the isolates recovered from coffee plants. Restriction fragment length polymorphism analysis revealed a high degree of conservation of the levansucrase locus (IsdA) among the 14 strains under study, which represented 11 different G. diazotrophicus genotypes. Targeted disruption of the lsdA gene in four representative strains abolished their ability to grow on sucrose, indicating that the endophytic species G. diazotrophicus utilises plant sucrose via levansucrase.

Abstract
Acetobacter diazotrophicus SRT4 secretes a constitutive levansucrase (LsdA) (EC 2.4.1.10) that is responsible for sucrose utilization. Immunogold electron microscopical studies revealed that LsdA accumulates in the periplasm before secretion. The periplasmic and extracellular forms of the enzyme were purified to homogeneity. Both proteins exhibited similar physical and biochemical characteristics indicating that LsdA adopts its final conformation in the periplasm. The N-terminal sequence of mature LsdA was pGlu-Gly-Asn-Phe-Ser-Arg as determined by PSD-MALDI-TOFMS (post-source decay-matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry). Comparison of this sequence with the predicted precursor protein revealed the cleavage of a 30-residue typical signal peptide followed by the formation of the pyroglutamic acid (pGlu) residue. Thus, in contrast with other Gram-negative bacteria, A. diazotrophicus secretes levansucrase by a signal-peptide-dependent mechanism.

Abstract
beta-Fructofuranosidases share a conserved aspartic acid-containing motif (Arg-Asp-Pro; RDP) which is absent from alpha-glucopyranosidases. The role of Asp-309 located in the RDP motif of levansucrase (EC 2.4.1.10) from Acetobacter diazotrophicus SRT4 was studied by site-directed mutagenesis. Substitution of Asp-309 by Asn did not affect enzyme secretion. The kcat of the mutant levansucrase was reduced 75-fold, but its Km was similar to that of the wild-type enzyme, indicating that Asp-309 plays a major role in catalysis. The two levansucrases showed optimal activity at pH 5.0 and yielded similar product profiles. Thus the mutation D309N affected the efficiency of sucrose hydrolysis, but not the enzyme specificity. Since the RDP motif is present in a conserved position in fructosyltransferases, invertases, levanases, inulinases and sucrose-6-phosphate hydrolases, it is likely to have a common functional role in beta-fructofuranosidases.

Abstract
A limited supply of organs is the main obstacle for organ transplantation. The shortage reflects not only a shortage of donors but also a failure to make use of existing donors. The Basque Country Transplant Coordination Team is an organ procurement organization that operates in the Basque country, an area of 7260 km2 with 2.1 million inhabitants. From January 1, 1990, to December 31, 1995, the number of potential cadaveric organ donors found by the team increased, to 70 donors per million inhabitants in 1995. Since 1993, the organization has had more than 30 donors per million persons and has procured more than 90 cadaveric organs, including more than 60 cadaveric kidneys, per million persons. Because of these rates, the team coordinated 61.7 cadaveric kidney transplants per million persons during 1995. This paper describes some characteristics of the Basque organ procurement organization that might explain these results.

Abstract
A prospective study was undertaken to determine whether stapedectomy can safely be performed in an outpatient setting. Twenty patients with otosclerosis amenable to surgical treatment were divided into two groups; those in the hospitalized group were admitted the day before surgery and discharged 24 hours after the procedure. The patients in the ambulatory group were admitted on the day surgery was scheduled and released 1 or 2 hours after the procedure. We analyzed the intensity and duration of postoperative vertigo, and the hearing gain obtained, studying the speech frequencies (500 to 2000 Hz) separately from the high frequencies (4000 to 8000 Hz). No significant difference was found at 4, 3, and 6 months of follow-up in any of the parameters studied, concluding that small-fenestra stapedectomy can safely be performed as an outpatient procedure.

Abstract
Acetobacter diazotrophicus, a nitrogen-fixing bacterium associated with sugar cane, secretes a levansucrase (sucrose-2,6-beta-D-fructan 6-beta-D-fructosyltransferase; EC 2.4.1.10). This enzyme is constitutively expressed and represents more than 70% of the total proteins secreted by strain SRT4. The purified protein consists of a single 58 kDa polypeptide with an isoelectric point of 5.5. Its activity is optimal at pH 5.0. It catalyses transfructosylation from sucrose to a variety of acceptors including water (sucrose hydrolysis), glucose (exchange reaction), fructan (polymerase reaction) and sucrose (oligofructoside synthesis). In vivo the polymerase activity leads to synthesis of a high-molecular-mass fructan of the levan type. A. diazotrophicus levansucrase catalyses transfructosylation via a Ping Pong mechanism involving the formation of a transient fructosyl-enzyme intermediate. The catalytic mechanism is very similar to that of Bacillus subtilis levansucrase. The kinetic parameters of the two enzymes are of the same order of magnitude. The main difference between the two enzyme specificities is the high yield of oligofructoside, particularly 1-kestotriose and kestotetraose, accumulated by A. diazotrophicus levansucrase during sucrose transformation. We discuss the hypothesis that these catalytic features may serve the different biological functions of each enzyme.

Abstract
In view of the controversy surrounding the role of environmental factors, such as the presence of bovine albumin in milk, or viral infections, in the etiology of IDDM, a study was undertaken to determine the relationship between these events and the subsequent risk of developing IDDM. On 40 venezuelan diabetic children (< 18 y) and forty, age, sex and race-matched controls were studied at the same time. Parents of children completed a questionnaire on the infant's feeding habits, its environment and family history. The X2 method and the Fischer's exact test were used to analyze the results. We found that 20% of the controls, and 10% of IDDM (NS), were never breast-fed. In 95% of controls vs 65% of IDDM (p < 0.001), cow's milk was given exclusively from birth, or combined with breast-feeding, 65% of IDDM and 60% of controls (NS) were breast-fed (alone or combined with milk substitutes) for more than three months. These results do not support the hypothesis that early exposure to breast milk substitutes increases the risk of IDDM in venezuelan children. The study revealed, however, that a family history of diabetes mellitus was present in 55% of IDDM vs 30% of controls (p < 0.05) and mumps infection before the onset of diabetes was recorded in 42.5% of IDDM in comparison with 12.5% of controls (p = 0.005). Other viral infections (rubella, chicken pox) had no statistical significance. The latter results suggest an association between a family history of diabetes mellitus and viral infections with the development of IDDM among this group of children.

Abstract
The purpose of this study was to define the mechanism whereby agonists that increase free cytosolic calcium (Cai2+) affect intracellular pH (pHi) in smooth muscle. Rat aortic vascular smooth muscle cells grown on coverslips were loaded with BCECF/AM or fura-2/AM for continuous monitoring of pHi or Cai2+, respectively, in a HCO3-/CO2- containing medium. Recovery from rapid increases in Cai2+ produced by 1 microM angiotensin (Ang) II (delta Cai2+ -229 +/- 43 nM) or 1 microM ionomycin (delta Cai2+ -148 +/- 19 nM) was accompanied by a fall in pHi (delta pHi, -0.064 +/- 0.0085 P < 0.01, and -0.05 +/- 0.012 pH units, P < 0.01, respectively). Neither the fall in pHi nor the rise in Cai2+ elicited by Ang II was prevented by pretreatment with agents which block the action of this agonist on pHi via the stimulation of the Cl/HCo3 exchangers (DIDS, 50 microM) or the Na+/H+ antiporter (EIPA, 50 microM). In the presence of DIDS and EIPA, Ang II produced a fall in pHi (delta pHi, -0.050 +/- 0.014, P < 0.01) and a rise in Cai2+ (delta Ca2+ 252 +/- 157 nM, P < 0.01). That the change in pHi was secondary to changes in Cai2+ was inferred from the finding that, when the rise in Cai2+ elicited by Ang II was prevented by preincubation with a Ca2+ buffer, BAPTA (60 microM), the fall in pHi was abolished as well (delta pHi, 0.0014 +/- 0.0046). The pHi fall produced by Ang II and ionomycin was prevented by cadmium at a very low concentration (20 nM) which is known to inhibit plasma membrane Ca(2+)-ATPase activity (delta pHi -0.002 +/- 0.0006 and -0.0016 pH units, respectively). Cadmium also blunted Cai2+ recovery after Ang II and ionomycin. These findings suggest that the fall in pHi produced by these agents is due to H+ entry coupled to Ca2+ extrusion via the plasma membrane Ca(2+)-ATPase. Our results indicate that agonists that increase Cai2+ cause intracellular acidification as a result of Ca2+/H+ exchange across the plasma membrane. This process appears to be mediated by a plasma membrane Ca(2+)-ATPase which, in the process of extruding Ca2+ from the cell, brings in [H+] and thus acidifies the cell.

Abstract
The visceral block, composed of both kidneys and their vascular pedicles, inferior vena cava, ureters and bladder, was removed from a 3-day-old male anencephalic donor and transplanted into a 32-year-old adult in chronic renal failure. The urinary tract was reconstructed by vesicovesicostomy for technical ease, and prevention of reflux and ureteral stenosis. Maximum urine output was 150 ml. per day and the kidney grafts were lost owing to rejection 5 months after transplantation.
