Abstract
Background
It is well known that statins, ezetimibe and other lipid lowering treatments such as Evolocumab (PCSK9-Inhibitor) reduce cardiovascular events by decreasing LDL-cholesterol (LDL-C) levels and slowing the progression of coronary atherosclerosis. Nevertheless, cardiovascular (CV) risk remains. Alirocumab, a PCSK9 inhibitor has demonstrated a reduction in cardiovascular events but its relationship with coronary atherosclerosis reduction has not been adequately demonstrated.
Purpose
The ARCHITECT trial sought to determine whether Alirocumab 150 mg/2 weeks is able to stop or reverse coronary atherosclerosis progression, by assessing coronary plaque burden (CPB) by serial multidetector computed tomography (MDCT).
Methods
A total of 104 patients with molecularly characterized heterozygous familial hypercholesterolaemia (FH) without clinical cardiovascular disease were enrolled in this trial. Patients had to have CPB >30% as documented by MDCT, be on maximum tolerated statin therapy with or without ezetimibe and LDL-C >100 mg/dL. Patients underwent a MDCT at enrollment and after 18-month treatment with alirocumab and they were analyzed by means of QAngio CT (Medis medical imaging system, the Netherlans). The pre-specified primary endpoint was change in CPB.
Results
Median age was 53.3 (46.2–59.4) years (54, 51.9% woman). Median LDL-cholesterol was 138.9 mg/dL. There was a significant reduction in the primary endpoint as Alirocumab reduced CPB from 34.6 (32.9–36.8)% to 30.4 (27.4–33.4)%. Significant reductions in LDL-C (67%) and atherosclerotic plaque volume were also found. Plaque regression as estimated by CPB was found in 91 (87.5%) patients. Main resuts may be found in figure 1.
Conclusions
Alirocumab demonstrated significant regression of CPB on MDCT over 18 months. ARCHITECT provides crucial mechanistic clues on coronary plaque behavior under the use of Alirocumab and its results could link and explain ODYSSEY-OUTCOMES results.

Abstract
Introduction Pendant l’épidémie par le COVID-19 plusieurs centres de dialyse ont arrêté de fournir des collations pendant la séance de dialyse par mesure de protection de propagation du virus. Le but de cette étude est d’évaluer l’état nutritionnel des patients hémodialysés chroniques avant et après la suspension des collations intradialytiques. Description Sur cette étude rétrospective on a étudié l’évolution des paramètres nutritionnelles de notre cohorte des patients hémodialysés pour 12 mois avant et après le 20/03/2020, date de suspension des collations pendant la dialyse à cause des mesures de protection contre la COVID-19. On a suivi l’évolution du poids, IMC, CRP, sérum Potassium et Phosphore avant la séance de dialyse, le taux d’albumine et prealbumine sérique ainsi que le nPCR (normalised Protein Catabolic Ratio). Méthodes Les résultats pour les paramètres continues sont présentés comme Moyenne ± Erreur standard moyenne. Pour l’analyse statistique on a effectué un t-test pour mesures indépendantes. Les résultats avec un p < 0,05 était considérés statistiquement significatifs. Résultats On a étudié 121 patients en hémodialyse (80 M,41F) avec un âge moyen à l’inclusion de 68,45 ± 0,45 ans. Ils étaient dialysés au moins depuis 6 mois dans un état stable. Un tiers de ces patients était diabétique. On a mesuré la moyenne des paramètres étudiés pour douze mois avant et après la suppression de collations intradialytiques (voir (Tableau 1). Ces collations comprenaient en moyenne de 395 kcal d’énergie (44 % des besoins journaliers), 13,3 g de protides (40 % des besoins journaliers). Il y avait une dégradation des paramètres nutritionnelles (poids, IMC, Albumine et Prealbumine serique ainsi que le nPCR après la suppression des collations confirmant leur rôle important sur l’état nutritionnel des patients hémodialysés chroniques. Conclusion En conclusion, la suppression des collations intradialytiques pendant la période épidémique de COVID-19 a aggravé les paramètres nutritionnels des patients en hémodialyse chronique.

Abstract
Background The Atacama salt flat is located in northern Chile, at 2300 m above sea level, and has a high concentration of lithium, being one of the main extraction sites in the world. The effect of lithium on microorganism communities inhabiting environments with high concentrations of this metal has been scarcely studied. A few works have studied the microorganisms present in lithium-rich salt flats (Uyuni and Hombre Muerto in Bolivia and Argentina, respectively). Nanocrystals formation through biological mineralization has been described as an alternative for microorganisms living in metal-rich environments to cope with metal ions. However, bacterial lithium biomineralization of lithium nanostructures has not been published to date. In the present work, we studied lithium-rich soils of the Atacama salt flat and reported for the first time the biological synthesis of Li nanoparticles. Results Bacterial communities were evaluated and a high abundance of Cellulomonas, Arcticibacter, Mucilaginibacter, and Pseudomonas were determined. Three lithium resistant strains corresponding to Pseudomonas rodhesiae, Planomicrobium koreense, and Pseudomonas sp. were isolated (MIC > 700 mM). High levels of S2− were detected in the headspace of P. rodhesiae and Pseudomonas sp. cultures exposed to cysteine. Accordingly, biomineralization of lithium sulfide-containing nanomaterials was determined in P. rodhesiae exposed to lithium salts and cysteine. Transmission electron microscopy (TEM) analysis of ultrathin sections of P. rodhesiae cells biomineralizing lithium revealed the presence of nanometric materials. Lithium sulfide-containing nanomaterials were purified, and their size and shape determined by dynamic light scattering and TEM. Spherical nanoparticles with an average size < 40 nm and a hydrodynamic size ~ 44.62 nm were determined. Conclusions We characterized the bacterial communities inhabiting Li-rich extreme environments and reported for the first time the biomineralization of Li-containing nanomaterials by Li-resistant bacteria. The biosynthesis method described in this report could be used to recover lithium from waste batteries and thus provide a solution to the accumulation of batteries.

Abstract
GnRH immunogens have been extensively employed in immunocontraception of animals. While they are effective, they are not 100% efficacious and of limited duration. GnRH secretion is dependent on upstream stimulation by kisspeptin. We therefore hypothesised that a dual immunogen combining GnRH and kisspeptin may be more efficacious through targeting two levels of the axis. We have previously shown GnRH immunogen elicits permanent sterilisation when sheep are vaccinated neonatally suggesting that the efficacy of GnRH immunisation may be dependent on the stage of reproductive development. We have now studied over 300 days the efficacy of immunisation with a dual immunogen comprising GnRH linked to kisspeptin via a hepatitis B T helper peptide sequence (GKT) administered to male and female rats prepubertally, pubertally and as adults. At all stages of development all immunised animals produced antibodies to GnRH, kisspeptin and GKT but differentially in titre with respect to sex and stage of development. In immunised adult, prepubertal and pubertal males testosterone and testes length was markedly reduced by 60 days and remained at low levels until day 150. Thereafter, testosterone recovered to pre immunisation levels and testes length increased to a maximum of about 40% of controls. 80% of males were infertile in three matings over 250 days. In prepubertal and pubertal female rats a single immunisation at day 0 reduced estradiol to low levels by day 60 which remained low until termination of the experiment on day 300. In matings of these females with fertile males on days 90, 120 and 250, 74% of prepubertal females were infertile and impressively, 100% (10/10) of pubertal females were infertile after a single immunisation on day 0. These findings set the scene for exploration of immunosterilisation of wild and domestic animals after a single immunisation.

Abstract
Heberprovac is a GnRH based vaccine candidate containing 2.4 mg of the GnRHm1-TT peptide as the main active principle; 245 μg of the very small size proteoliposomes adjuvant (VSSP); and 350 μL of Montanide ISA 51 VG oil adjuvant. The aim of this study was to assess the safety and tolerance of the Heberprovac in advanced prostate cancer patients as well as its capacity to induce anti-GnRH antibodies, the subsequent effects on serum levels of testosterone and PSA and the patient overall survival. The study included eight patients with histologically-proven advanced prostate cancer with indication for hormonal therapy, who received seven intramuscular immunizations with Heberprovac within 18 weeks. Anti-GnRH antibody titers, testosterone and PSA levels, as well as clinical parameters were recorded and evaluated. The vaccine was well tolerated. Significant reductions in serum levels of testosterone and PSA were seen after four immunizations. Castrate levels of testosterone were observed in all patients at the end of the immunization schedule, which remained at the lowest level for at least 20 months. In a 10-year follow-up three out of six patients who completed the entire trial survived. In contrast only one out eight patients survived in the same period in a matched randomly selected group receiving standard anti-hormonal treatment. Heberprovac vaccination showed a good security profile, as well as immunological, biochemical and, most importantly, clinical benefit. The vaccinated group displayed survival advantage compared with the reference group that received standard treatment. These results warrant further clinical trials with Heberprovac involving a larger cohort.

Abstract
Conventional IVF has not yet been implemented in the equine species. One of the main reasons has been the inability to develop a culture medium and incubation conditions supporting high levels of stallion sperm capacitation and hyperactivation in vitro. Although different culture media have been used for this purpose, human tubal fluid (HTF) medium, widely used in the manipulation of human and mice gametes, has not been reported so far in stallion sperm culture. Thus, the first part of this study aimed to compare HTF (Summers and Biggers, 2003 Hum. Reprod. Update9, 557-582, DOI: 10.1093/humupd/dmg039) and Whitten’s (McPartlin et al. 2009 Biol. Reprod.81, 199-206, DOI: 10.1095/biolreprod.108.074880) media on different stallion sperm quality and capacitation variables. Additionally, the effect of procaine, aminopyridine and caffeine on sperm motility parameters was evaluated in both media at different incubation times. Fresh semen from 3 Chilote stallions was collected, diluted to 10×106 sperm mL−1 in capacitating (7mg mL−1 BSA and 25mM NaHCO3) and non-capacitating (without BSA and NaHCO3) HTF and Whitten’s media and incubated for 30 and 120min at 38°C in air atmosphere. Integrity and destabilisation of the plasma membrane were evaluated by merocyanine 540/SYTOX Green (MC540), mitochondrial membrane potential (ΔΨm) using tetramethylrhodamine methyl ester perchlorate, acrosome membrane integrity by peanut agglutinin/fluorescein isothiocyanate and tyrosine phosphorylation by P-tyrosine mouse mAb conjugated to Alexa Fluor® in a FACSCanto II flow cytometer (Becton, Dickinson and Co., Franklin Lakes, NJ, USA). A total of 10,000 sperm events were acquired from each measurement (n=3 replicates for each stallion). Motility parameters were evaluated using the integrated semen analysis system (ISAS®, Selinion Medical, Brussels, Belgium). Percentage data were arcsine transformed and subjected to a 2-way ANOVA with Bonferroni’s post hoc test using Prism 7 software (GraphPad Software, La Jolla, CA, USA). We found no differences between Whitten’s and HTF media in terms of sperm viability, uninduced acrosome membrane damage or mitochondrial membrane potential at 30 and 120min of incubation. Membrane fluidity (MC540) increased in both media at 30 and 120min of incubation compared with non-capacitating conditions. Similarly, tyrosine phosphorylation increased in both media in capacitating conditions at 2 and 4h of incubation compared with non-capacitating conditions, without differences between media. Although procaine showed the best result in terms of sperm hyperactivated motility in both media, aminopyridine also showed parameters consistent with hyperactivation including an increase in curvilinear velocity and decrease in straightness. In conclusion, HTF medium and aminopyridine equally support capacitation-related parameters in stallion sperm.

Abstract
In a previous study aimed to design a novel prostate cancer vaccine, the authors of the present study demonstrated the advantage of combining the adjuvants Montanide ISA 51 with very small size proteoliposomes (VSSP) to promote a significant humoral immune response to gonadotropin-releasing hormone (GnRH) in healthy animals. The present study compared the efficacy of this vaccine formulation versus the standard treatment currently available in terms of preventing the development of tumors in DD/S mice injected with Shionogi carcinoma (SC) 115 cells. The results demonstrated that 5 non-vaccinated control mice exhibited a fast tumor growth, and succumbed to the disease within 19-31 days. Mice immunized with the GnRH/Montanide ISA 51/VSSP vaccine exhibited a moderate decline in testosterone levels that was associated with a decrease in anti-GnRH antibody titers, which lead to a sustained tumor growth inhibition. In total, 2 mice in the immunized group exhibited complete remission of the tumor for the duration of the present study. In addition, castrated mice, which were used as a control for standard hormonal therapy, exhibited an accelerated decrease in tumor size. However, tumor relapse was observed between days 50 and 54, and between days 65 and 85, following the injection of SC 155 cells. Therefore, these mice were sacrificed at day 90. The present study concludes that the slow and moderate reduction of testosterone levels observed using the GnRH-based vaccine may delay the appearance of castration resistance in a Shionogi prostate cancer model. These findings suggest that this vaccine may be used to delay castration resistance in patients with prostate cancer.

Abstract
INTRODUCTION Self-determination theory postulates that the three basic psychological needs of autonomy, competence and relatedness have to be satisfied for students to achieve intrinsic motivation and internalisation of autonomous self-regulation towards academic activities. Consequently, the influence of the clinical teaching environment becomes crucial when satisfying these needs, particularly when promoting or diminishing students' intrinsic motivation. The aim of this study was to describe and understand how clinical teachers encourage intrinsic motivation in undergraduate dental students based on the three basic psychological needs described by the self-determination theory. METHODS A qualitative case study approach was adopted, and data were collected through semistructured interviews with nine experienced undergraduate clinical teachers of one dental school in Santiago, Chile. Interview transcripts were analysed by two independent reviewers using a general inductive approach. FINDINGS Several themes emerged outlining teaching strategies and behaviours. These themes included the control of external motivators; gradual transference of responsibility; identification and encouragement of personal interests; timely and constructive feedback; delivery of a vicarious learning experience; teamwork, team discussion, and presence of a safe environment, amongst others. Overall, teachers stressed the relevance of empowering, supporting and building a horizontal relationship with students. CONCLUSIONS Our findings regarding dental education expand on the research outcomes from other health professions about how teachers may support students to internalise behaviours. An autonomy-supportive environment may lead students to value and engage in academic activities and eventually foster the use of an autonomy-supportive style to motivate their patients.

Abstract
With the goal of providing the first example of application of a recently proposed method, thus demonstrating its ability to give results in principle, global stability of a version of the rotating Couette flow is examined. The flow depends on the Reynolds number and a parameter characterizing the magnitude of the Coriolis force. By converting the original Navier–Stokes equations to a finite-dimensional uncertain dynamical system using a partial Galerkin expansion, high-degree polynomial Lyapunov functionals were found by sum-of-squares of polynomials optimization. It is demonstrated that the proposed method allows obtaining the exact global stability limit for this flow in a range of values of the parameter characterizing the Coriolis force. Outside this range a lower bound for the global stability limit was obtained, which is still better than the energy stability limit. In the course of the study, several results meaningful in the context of the method used were also obtained. Overall, the results obtained demonstrate the applicability of the recently proposed approach to global stability of the fluid flows. To the best of our knowledge, it is the first case in which global stability of a fluid flow has been proved by a generic method for the value of a Reynolds number greater than that which could be achieved with the energy stability approach.

Abstract
Human respiratory syncytial virus (HRSV) is one of the most common viral aetiological agents in the youngest population. In the present study a novel HRSV-B BA genotype is first described based on the phylogenetic analysis of the coding hypervariable region 2 sequences of G protein from strains detected during the 2014-2015 season. Among all strains detected in the last season, 44% belonged to this new genotype. Therefore, it highlights the importance of a continuous HRSV surveillance to monitor the emergence and spread of new genotypes or variants with genetic changes that may affect antigenic and tropism features.

Abstract
BACKGROUND AND AIMS Reduction of cardiovascular risk with high consumption of fish in diet is still a matter of debate, and concerns about heavy metal contamination have limited consumption of oily fish. We aimed to evaluate the effect of regular ingestion of white fish on cardiovascular risk factors in patients with metabolic syndrome. METHODS AND RESULTS Multicenter randomized crossover clinical trial including 273 individuals with metabolic syndrome. An 8-week only-one dietary intervention: 100 g/d of white fish (Namibia hake) with advice on a healthy diet, compared with no fish or seafood with advice on a healthy diet. Outcomes were lipid profile, individual components of the metabolic syndrome, serum insulin concentrations, homeostasis model of insulin resistance, serum C-reactive protein and serum fatty acid levels. We found a significant lowering effect of the intervention with white fish on waist circumference (P < 0.001) and diastolic blood pressure (P = 0.014). A significant lowering effect was also shown after the dietary intervention with fish on serum LDL concentrations (P = 0.048), whereas no significant effects were found on serum HDL or triglyceride concentrations. A significant rise (P < 0.001) in serum EPA and DHA fatty acids was observed following white fish consumption. Overall adherence to the intervention was good and no adverse events were found. CONCLUSION In individuals with metabolic syndrome, regular consumption of hake reduces LDL cholesterol concentrations, waist circumference and blood pressure components of the metabolic syndrome.

Abstract
BACKGROUND AND AIMS rs17321515 SNP has been associated with variation in LDL-C, high density lipoprotein cholesterol and triglycerides concentrations. This effect has never been studied in patients with severe hypercholesterolemia. Therefore, our aims were to assess the association of the rs17321515 (TRIB1) SNP with plasma lipids concentrations and anthropometric variables and to explore the interaction between this SNP and some classic risk factors in patients with familial hypercholesterolemia (FH). METHODS AND RESULTS rs17321515 SNP was genotyped in 531 subjects with genetic diagnosis of FH. Homozygous A/A had significantly higher waist circumference compared with G/G subjects (P = 0.006) and carriers of the minor allele G (P = 0.039). Interestingly, smokers homozygous for the A allele displayed higher plasma triglycerides concentrations (P = 0.029), higher VLDL-C levels (P = 0.023) and higher TC/HDL-C ratio (P = 0.035) than carriers of the minor allele G. In addition, homozygous A/A with the presence of arcus cornealis displayed lower plasma ApoA-I levels (P = 0.024) and higher TC/HDL-C ratio (P = 0.046) than carriers of the minor allele G. CONCLUSIONS Smoking status and presence of arcus cornealis modulate the effect of rs17321515 (TRIB1) polymorphism on plasma lipids levels in patients with FH. These results could explain the differences in the susceptibility to coronary heart disease in these patients.

Abstract
INTRODUCTION The aim of this study was to identify predictive factors of success following a single-session of shock wave lithotripsy (SWL) at 3 weeks of follow-up in our center. MATERIAL AND METHODS The medical records of 116 patients with solitary urinary calculi who underwent single-session SWL in our department between October 2007 and August 2009 were reviewed. All preoperative unenhanced computed axial tomographies were reviewed by two radiologists blinded to clinical outcome. Success was defined as complete clearance or the persistence of fragments ≤ 2 mm on a plain film at 3 weeks of follow-up. The impact of clinical and radiological factors on success was assessed by univariate and multivariate analyses. RESULTS The single-session SWL success rate at 3 weeks was 49.1%. Stone size <8 mm, stone area < 30 mm(2), stone location (mid- and distal ureter), stone density <1000 HU and intraoperative fragmentation showed a significant association with SWL success in the univariate analysis (p<0.05). Stone area (OR 2.9), ureteral stone location (OR 3.4) and intraoperative fragmentation (OR 4.2) were the only predictors of success in the multivariate analysis. CONCLUSIONS Stone area and ureteral stone location provide important information when deciding about the indication of a SWL in a patient with stone disease. However, successful resolution of only half of the cases after a single session at 3 weeks in our series undermines the relevance of informing patients about the potential need for additional treatment.

Abstract
Prostate growth, development, functions, and neoplastic transformation is androgen dependent. Estrogens have similar effects in the ovary and breast. Previous studies using gonadotrophin releasing hormone (GnRH/LHRH) vaccines have shown the usefulness of immunization against this hormone in prostate (PC) and breast cancer (BC). We have synthesized a peptide mutated at position 6 and attached to the 830-844 tetanic toxoid (TT) helper T cell sequence in the same synthesis process. After repeated pig immunizations, we have demonstrated a vaccine that significantly decreased testes size (p < 0.001), prostate (p < 0.01), seminal vesicles (p < 0.01), and testosterone (T) castration [0.05 nM ml(-1) (p < 0. 01)]. Similar results were obtained in adult male and female healthy dogs and Macaca fascicularis models. These data indicate that this GnRHm1-TT vaccine is safe and able to induce significant tumor growth inhibition in the Dunning R3327-H rat androgen responsive prostate tumor model. In these rats, the immunization induced high anti-GnRH titers concomitant with T castration reduction (p < 0.01) in 90% of the animals tested. In addition, 70% of the responders exhibited tumor growth inhibition (p = 0.02) and a survival rate approximately three times longer that those of untreated rats. These data indicate that GnRHm1-TT vaccine may be a potential candidate in the treatment of PC, BC, and other hormone-dependent cancers.

Abstract
BACKGROUND Familial hypercholesterolemia (FH) is associated with a high risk of coronary heart disease. Pharmacological treatment and diet are both essential for the management of FH. Foods rich in plant sterols (PS) may play an important role in the treatment of patients with these disorders. OBJECTIVE To test the effect of the intake of PS on low-density lipoprotein (LDL) concentration, endothelial function (EF) and LDL particle size in 30 patients with FH. DESIGN Randomized and crossover dietary intervention study. SETTING Tertiary outpatient care. SUBJECTS Thirty-eight were recruited, but only 30 were subjected to four low-fat dietary intervention periods, each of 4 weeks. METHODS Each intervention had a different content of cholesterol (<150 or 300 mg/day) and sitosterol (<1 or 2 g/day). Lipid response, EF and LDL particle size were analysed after the intervention. RESULTS Plasma sitosterol/cholesterol ratio was higher during both plant sterol-rich periods than during the low plant sterols periods. Basal sitosterol concentrations predicted the LDL-cholesterol response during the intake of plant sterol-enriched diets. The change in LDL-cholesterol was significantly greater in subjects in the upper and intermediate tertiles of basal plasma sitosterol concentrations (-21+/-8 mg/dl, P=0.03; -19+/-7 mg/dl, P=0.04, respectively) than in subjects in the lower tertile (8+/-5 mg/dl) when they changed from a low cholesterol diet to a low cholesterol plus plant sterol diet. CONCLUSION Our study demonstrates that basal sitosterol values can predict hypolipidemic response in patients with FH.

Abstract
This paper analyzes the dynamics of cell proliferation in the developing central nervous system. Three different algorithms, Fano factor, Allan factor and detrended fluctuations analysis, are used to estimate de scaling exponent of space numerical series obtained by recording the number and position of proliferating cells along the cephalic-caudal axis of the system. It can be concluded that the dynamics of proliferation involves two component: (a) a random noncorrelated stochastic component representing a basal proliferating activity uniformly distributed along the cephalic-caudal axis and (b) a deterministic nonstationary component that imposes a defined global trend to the process. The deterministic nonstationary trend can be interpreted as the effect of a controlling influence operating along the cephalic-caudal axis. This result indicates that the proliferative activity is spatially organized along the cephalic-caudal axis of the system.

Abstract
AIMS To investigate the role of HMG-CoA reductase inhibitor (statin) treatment during serum glucose variations on plasma oxidized LDL (ox-LDL) levels in obese patients with early Type 2 diabetes mellitus (T2D) and its relationship to endothelial biomarkers. METHODS In a double-blind, randomized crossover study, 15 obese diet-treated T2D patients received cerivastatin (0.4 mg/day) or placebo for 3 months. Circulating ox-LDL levels were measured fasting and during a euglycaemic-hyperinsulinaemic clamp (approximately 5.5 mmol/l; EHC) and a hyperglycemic clamp (approximately 20 mmol/l; HC). An endothelium-dependent flow-mediated dilation (FMD) study was carried out and urinary albumin excretion (UAE) was measured at rest and during EHC. S-ICAM, s-VCAM and basal prothrombotic factors were also measured. RESULTS During cerivastatin treatment, basal circulating ox-LDL levels decreased by 48% (P<0.001) compared with placebo. Serum ox-LDL levels decreased during EHC and remained unchanged during HC compared with the fasting state; with cerivastatin treatment these levels were lower compared with placebo both in the fasting state and during the clamp studies. FMD was higher with cerivastatin than with placebo (P<0.001) and the increments in FMD correlated with decrements in serum ox-LDL levels (r=0.78, P=0.001). Microalbuminuria increased during EHC but this was blunted during cerivastatin therapy compared with placebo (P<0.05). Basal sICAM-1 and sVCAM-1 levels decreased (P<0.01 and P<0.05, respectively). CONCLUSIONS In early obese Type 2 diabetic patients, serum ox-LDL levels are influenced by short-term serum glucose variations and lowered with cerivastatin therapy. During cerivastatin treatment, improved flow-mediated endothelium-dependent dilation was associated with decrements in circulating ox-LDL levels and the hyperinsulinaemia-induced urinary albumin excretion was blunted.

Abstract
Paraoxonase 1 (PON 1) is an esterase with antioxidant properties that is present in HDL. Gln192Arg polymorphism (also named Q192R or Q/R) of the PON 1 gene that encodes this protein defines two alleles (Q and R). The R allele has been associated with higher cardiovascular risk. LDL size and susceptibility to oxidation also have been identified as cardiovascular risk factors. Our objective was to determine whether genetic variations in the Gln192Arg polymorphism influence LDL size and susceptibility to oxidation after the consumption of diets with different fat content. In our experiments, the participants (n = 98) underwent three 4-wk diets--one, saturated fat-enriched (SAT); another, monounsaturated fat-enriched (MONO); and a third, carbohydrate-enriched (CHO). We observed that LDL were smaller in the QQ group after the CHO diet vs. the SAT (P < 0.01) and MONO diets (P < 0.03). No differences in LDL size were found in QR/RR subjects. When we analyzed lag time of oxidation of LDL, we found that when carriers of the R allele (QR/RR) received the MONO diet, the lag period of LDL oxidation was longer as compared with the CHO diet. Otherwise, we found no differences in QQ homozygotes when we evaluated the lag time of oxidation of LDL after the three diets. These results suggest that the Glnl92Arg polymorphism of the paraoxonase gene influences LDL size and susceptibility to oxidation in response to diet.

Abstract
It has recently been reported that carriers of the less common allele at the scavenger receptor class B type I (SR-BI) exon 1 polymorphism are more susceptible to the presence of saturated fatty acid in the diet because of a greater increase in LDL cholesterol. Our aim was to determine if this polymorphism could also influence postprandial lipoprotein metabolism, because the SR-BI has been described as a possible mediator in the intestinal absorption of triacylglycerols. Forty-seven normolipidemic volunteers who were homozygous for the E3 allele at the APOE gene were selected [37 homozygous for the common genotype (1/1) at the SR-BI exon 1 polymorphism and 10 heterozygous (1/2)]. They were given a fat-rich meal containing 1 g fat and 7 mg cholesterol per kg body weight and vitamin A 60,000 IU/m2 body surface. Fat accounted for 60% of calories, and protein and carbohydrates accounted for 15% and 25% of energy respectively. Blood samples were taken at time 0, every 1 h until 6 h, and every 2.5 h until 11 h. Total cholesterol and triacylglycerols in plasma, and cholesterol, triacylglycerols and retinyl palmitate in triacylglycerol-rich lipoproteins (large and small triacylglycerol-rich lipoproteins) were determined. Postprandial responses for triacylglycerols and retinyl palmitate in small triacylglycerol-rich lipoproteins were higher in 1/1 individuals than in 1/2 individuals. No other significant differences were noted. Our data show that the presence of the genotype 1/2 is associated with a lower postprandial lipemic response.

Abstract
The aim of this study was to carry out a nationwide survey to assess the susceptibility of clinical isolates of four respiratory pathogens against nine antibiotics. Eight Spanish centers participated in the study, collecting a total of 977 isolates of Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis. The susceptibility of S. pneumoniae to penicillin was 37.46% susceptible, 30.43% intermediate and 32.11% resistant. MIC(90) of all antibiotics against this microorganism were 48 mg/l, except cefaclor, cefixime and azithromycin. For S. pyogenes, all the strains were susceptible to penicillins and cephalosporins, and azithromycin was the least active with a rate of resistance of 11.43%. A total of 95 isolates of H. influenzae were betalactamase positive (26.32%). With regard to M. catarrhalis, only penicillin and amoxicillin showed MICs(90) >=8 mg/l.

Abstract
BACKGROUND AND AIM The effect of the quality of dietary fat on body composition is unknown. Our objective was to determine whether body composition is modified by the isocaloric substitution of a diet rich in saturated fat by a diet high in monounsaturated fat (Mediterranean diet) or a carbohydrate-rich diet in overweight subjects with hypercholesterolemia. METHODS AND RESULTS The study involved 34 hypercholesterolemic males aged 18-63 years with a body mass index (BMI) of 28.2 (2.6), all of whom consumed a diet rich in saturated fat (SAT) for 28 days. They were then randomly divided into two groups of 17 subjects and underwent two dietary periods of 28 days each in a crossover design: a Mediterranean diet high in monounsaturated fat (MONO) and a carbohydrate-rich diet (CHO). The order of the diets was different for the two group. The CHO diet contained 57% CHO and 28% total fat (< 10% saturated fat, 12% monounsaturated fat and 6% polyunsaturated fat); the Mediterranean diet contained 47% CHO and 38% fat (< 10% saturated fat, 22% monounsaturated fat--75% of which was provided by olive oil- and 6% polyunsaturated fat). The variables measured at the end of each dietary intervention period were: 1) body composition by means of bioelectrical impedance; 2) plasma lipoproteins using enzymatic techniques; and 3) fatty acids in cholesterol esters by means of gas chromatography. BMI and the waist/hip ratio remained the same during the three dietary periods. A decrease in fat was observed when changing from a saturated fat diet (23.3 (6.3) kg) to a Mediterranean diet (20.8 (7.2) kg) (p < 0.05), or a carbohydrate-rich diet (20.6 (6.7) kg) (p < 0.05). Lean mass increased when changing from a SAT diet (58.4 (7.0) kg) to a CHO diet (60.2 (7.0) kg) (p < 0.05). CONCLUSION The isocaloric substitution of a saturated fat-rich diet by a Mediterranean or carbohydrate-rich diet decreases total body fat in hypercholesterolemic males.
