Abstract
Brain states such as sleep, anesthesia, wakefulness, or coma are characterized by specific patterns of cortical activity dynamics, from local circuits to full-brain emergent properties. We previously demonstrated that full-spectrum signals, including the infraslow component (DC, direct current-coupled), can be recorded acutely in multiple sites using flexible arrays of graphene solution-gated field-effect transistors (gSGFETs). Here, we performed chronic implantation of 16-channel gSGFET arrays over the rat cerebral cortex and recorded full-band neuronal activity with two objectives: (1) to test the long-term stability of implanted devices; and (2) to investigate full-band activity during the transition across different levels of anesthesia. First, we demonstrate it is possible to record full-band signals with stability, fidelity, and spatiotemporal resolution for up to 5.5 months using chronic epicortical gSGFET implants. Second, brain states generated by progressive variation of levels of anesthesia could be identified as traditionally using the high-pass filtered (AC, alternating current-coupled) spectrogram: from synchronous slow oscillations in deep anesthesia through to asynchronous activity in the awake state. However, the DC signal introduced a highly significant improvement for brain-state discrimination: the DC band provided an almost linear information prediction of the depth of anesthesia, with about 85% precision, using a trained algorithm. This prediction rose to about 95% precision when the full-band (AC + DC) spectrogram was taken into account. We conclude that recording infraslow activity using gSGFET interfaces is superior for the identification of brain states, and further supports the preclinical and clinical use of graphene neural interfaces for long-term recordings of cortical activity.

Abstract
OBJECTIVE In recent years, safety concerns about modafinil exposure during pregnancy have emerged. In particular, increased risks for major congenital anomalies (MCA) and impaired fetal growth were reported, although study results were conflicting. Our investigation aims to examine previously reported safety signals. METHOD Multicenter case series based on data from 18 Teratology Information Services from 12 countries. Modafinil exposed pregnancies with an estimated date of birth before August 2019 were included in this study. For prospectively ascertained pregnancies, cumulative incidences of pregnancy outcomes, rate of nonchromosomal MCA in first trimester exposed pregnancies and percentiles of neonatal/infant weight and head circumference (HC) were calculated. Potential dose-dependent effects on fetal growth were explored by linear regression models. Retrospectively ascertained cases were screened for pattern of MCA and other adverse events. RESULTS One hundred and seventy-five prospectively ascertained cases were included, of which 173 were exposed at least during the first trimester. Cumulative incidences for live birth, spontaneous abortion and elective termination of pregnancy were 76.9% (95% CI, 68.0%-84.8%), 9.3% (95% CI, 5.0%-16.9%), and 13.9% (95% CI, 8.1%-23.1%), respectively. Nonchromosomal MCA was present in 3/150 live births, corresponding to an MCA rate of 2.0% (95%CI, 0.6%-6.1%), none were reported in pregnancy losses. Compared to reference standards, birth weight (BW) tended to be lower and neonatal HC to be smaller in exposed newborns (data available for 144 and 73 of 153 live births, respectively). In nonadjusted linear regression models, each 100 mg increase of average dosage per pregnancy day was associated with a decrease in standard deviation score (SDS) of -0.28 SDS (95% CI, -0.45 to -0.10) for BW and of -0.28 SDS (95% CI, -0.56 to 0.01) for HC. Screening of 22 retrospectively reported cases did not reveal any specific pattern of MCA or other adverse outcomes. CONCLUSION The results do not indicate an increased risk of MCA after in utero exposure to modafinil, but a tendency toward lower BW and reduced neonatal HC. However, these findings should be regarded as preliminary. Until further studies allow for a definite conclusion, modafinil should not be used during pregnancy.

Abstract
Personalized nutrition (PN) has gained much attention as a tool for empowerment of consumers to promote changes in dietary behavior, optimizing health status and preventing diet related diseases. Generalized implementation of PN faces different obstacles, one of the most relevant being metabolic characterization of the individual. Although omics technologies allow for assessment the dynamics of metabolism with unprecedented detail, its translatability as affordable and simple PN protocols is still difficult due to the complexity of metabolic regulation and to different technical and economical constrains. In this work, we propose a conceptual framework that considers the dysregulation of a few overarching processes, namely Carbohydrate metabolism, lipid metabolism, inflammation, oxidative stress and microbiota-derived metabolites, as the basis of the onset of several non-communicable diseases. These processes can be assessed and characterized by specific sets of proteomic, metabolomic and genetic markers that minimize operational constrains and maximize the information obtained at the individual level. Current machine learning and data analysis methodologies allow the development of algorithms to integrate omics and genetic markers. Reduction of dimensionality of variables facilitates the implementation of omics and genetic information in digital tools. This framework is exemplified by presenting the EU-Funded project PREVENTOMICS as a use case.

Abstract
Abstract
Introduction
Liposarcomas are malignant neoplasms that originate in fatty mesenchymal tissue and are the most common histological subtype of soft tissue sarcomas. They account for 1% of solid tumors in adults and are located mainly in the extremities, with the retroperitoneum being the second most frequent location. Given the rarity and aggressiveness of these tumors, it is advisable to establish a multidisciplinary approach towards them in order to improve the prognosis of patients.
Clinical case
Patient who was operated upon on a scheduled and outpatient basis for a left inguinal hernia. During surgery, a preperitoneal tumor was identified that was removed and revealed a high-grade dedifferentiated liposarcoma. In a second surgical act, a tumor mass of about 10 centimeters in length was found, lodged in the left pelvis and contacting sigma, which extended into the inguinal duct and scrotal pouch. Finally, compartment surgery and a left orchiectomy with end-to-end colo-sigmoid anastomosis were performed.
Discussion
Routine examination of the masses contained in the hernial sacs is recommended since, despite their infrequency (<0.1%), cases of liposarcomas that have their origin in the inguinal canal have been described. Surgery for retroperitoneal sarcomas must be compartmental, which requires the inclusion of viscera close to the tumor in the resection. Complete surgical resection R0 is the only potentially curative treatment. Compartment surgery should be performed by expert surgeons in referral centers with multidisciplinary teams to improve the prognosis of these patients.

Abstract
INTRODUCTION Multiple sclerosis mainly affects women of childbearing age, and the pregnancy and postpartum period is of special interest because of the peculiarities of the disease course and the therapeutic consequences that derive from it. During the period of breastfeeding (BF), the choice of treatment strategy must weigh up the well-established benefits of BF for both the newborn and the mother against the safety profile and potential adverse effects on the infant resulting from exposure to disease-modifying drugs transferred through breast milk. DEVELOPMENT The study reviews the current evidence on the safety of disease-modifying drugs available for the treatment of multiple sclerosis during the BF period, and gathers data on the transfer of the different drugs into breast milk, as well as the potential adverse effects described in the infant. The drugs of first choice during this period are interferon beta and glatiramer acetate. The rest of the disease modifying drugs are not accepted for use in the BF period according to their summary of product characteristics. However, in recent years, data from studies of clinical practice and case series have been published suggesting that some of these drugs could be used safely during this period. CONCLUSIONS Given the recognised health benefits of BF for both mother and infant, exclusive breastfeeding is recommended whenever possible. It is essential to carry out an individualised assessment prior to pregnancy and to evaluate the different treatment options depending on each patient.

Abstract
In the framework of the research project called fitomatics, we have isolated and characterized a bacterial plant-endophyte from the rhizomes of Iris germanica, hereafter referred to as strain FIT81T. The bacterium is Gram negative, rod-shaped with lophotrichous flagella, and catalase- and oxidase-positive. The optimal growth temperature of strain FIT81T is 28 °C, although it can grow within a temperature range of 4–32 °C. The pH growth tolerance ranges between pH 5 and 10, and it tolerates 4% (w/v) NaCl. A 16S rRNA phylogenetic analysis positioned strain FIT81T within the genus
Pseudomonas
, and multilocus sequence analysis revealed that
Pseudomonas gozinkensis
IzPS32dT,
Pseudomonas glycinae
MS586T,
Pseudomonas allokribbensis
IzPS23T, 'Pseudomonas kribbensis' 46–2 and
Pseudomonas koreensis
PS9-14T are the top five most closely related species, which were selected for further genome-to-genome comparisons, as well as for physiological and chemotaxonomic characterization. The genome size of strain FIT81T is 6 492 796 base-pairs long, with 60.6 mol% of G+C content. Average nucleotide identity and digital DNA–DNA hybridization analyses yielded values of 93.6 and 56.1%, respectively, when the FIT81T genome was compared to that of the closest type strain
P. gozinkensis
IzPS32dT. Taken together, the obtained genomic, physiologic and chemotaxonomic data indicate that strain FIT81T is different from its closest relative species, which lead us to suggest that it is a novel species to be included in the list of type strains with the name Pseudomonas fitomaticsae sp. nov. (FIT81T=CECT 30374T=DSM 112699T).

Abstract
The emergency of the coronavirus disease 2019 (COVID-19) pandemic led to the off-label use of drugs without data on their toxicity profiles in patients with COVID-19, or on their concomitant use. Patients included in the COVID-19 Patient Registry of a tertiary hospital during the first wave were analyzed to evaluate the adverse drug reactions (ADRs) with the selected treatments. Twenty-one percent of patients (197 out of 933) had at least one ADR, with a total of 240 ADRs. Patients with ADRs were more commonly treated with multiple drugs for COVID-19 infection than patients without ADRs (p < 0.001). They were younger (median 62 years vs. 70.1 years; p < 0.001) and took less medication regularly (69.5% vs. 75.7%; p = 0.031). The most frequent ADRs were gastrointestinal (67.1%), hepatobiliary (10.8%), and cardiac disorders (3.3%). Drugs more frequently involved included lopinavir/ritonavir (82.2%), hydroxychloroquine (72.1%), and azithromycin (66.5%). Although most ADRs recovered without sequelae, fatal cases were described, even though the role of the disease could not be completely ruled out. In similar situations, efforts should be made to use the drugs in the context of clinical trials, and to limit off-label use to those drugs with a better benefit/risk profile in specific situations and for patients at high risk of poor disease prognosis.

Abstract
Through bacterial plant–endophyte extraction from rhizomes of Iris germanica plant, a Gram-stain-negative, aerobic, catalase- and oxidase-positive gammaproteobacterial strain, referred to as FIT28T, was isolated. FIT28T shows vigorous growth on nutrient rich media within the temperature range of 4–35 °C, with optimal growth at 28 °C, a wide pH tolerance from pH 5 to 11, and salt tolerance up to 6 % (w/v) NaCl. Colonies are white-yellow and quickly become mucoid. The results of analysis of the 16S rRNA gene sequence placed the strain within the genus
Pseudomonas
, and multilocus sequence analysis (MLSA) using 16S rRNA, rpoB, gyrB and rpoD concatenated sequences revealed that the closest relatives of FIT28T are
Pseudomonas zeae
OE48.2T, '
Pseudomonas crudilactis
' UCMA 17988,
Pseudomonas tensinigenes
ZA5.3T,
Pseudomonas helmanticensis
OHA11T,
Pseudomonas baetica
a390T,
Pseudomonas iridis
P42T,
Pseudomonas atagonensis
PS14T and
Pseudomonas koreensis
Ps 9-14T, within the
Pseudomonas koreensis
subgroup of the
Pseudomonas fluorescens
lineage. The genome size of FIT28T is about 6.7 Mb with 59.09 mol% DNA G+C content. Average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values calculated from the genomic sequences of FIT28T, and the closely related
P. zeae
OE48.2T are 95.23 and 63.4 %, respectively. Biochemical, metabolic and chemotaxonomic studies further support our proposal that Pseudomonas germanica sp. nov., should be considered a novel species of the genus
Pseudomonas
. Hence, the type strain FIT28T (=LMG 32353T=DSM 112698T) has been deposited in public cell-type culture centres.

Abstract
AIM To retrospectively analyse hospital outpatient treatment (HOT) withdrawal due to unacceptable toxicity at our hospital. Information regarding unacceptable toxicity leading to treatment withdrawal was recorded. METHODS HOT interruptions because of unacceptable toxicity were identified from the Register of Patients and Treatments (RPT) (January 2014 to December 2017). Information regarding the demographic and clinical characteristics of patients, adverse drug reactions (ADRs) and drug treatments was retrieved from electronic health records. Causality and previous knowledge of ADRs were assessed according to the Spanish Pharmacovigilance System algorithm. Information regarding HOT risk management plans (RMPs) and their classification as inverted black triangle medicines was obtained from the European Medicines Agency (EMA). RESULTS HOTs were withdrawn due to unacceptable toxicity in 136 (1.5%) registries corresponding to 135 (1.7%) patients. Fifty-one different HOTs (38.6% of those registered) were involved in 240 ADR/HOT pairs: 24 (47%) were additional monitoring medicines and 37 (72.5%) were EMA RMPs. The most frequent medicines involved in ADRs were lenalidomide (30, 12.5%) (mainly neutropenia, thrombocytopenia and bicytopenia), bevacizumab (19, 7.9%) (mainly venous and pulmonary thromboembolism) and sunitinib (13, 5.4%) (mainly thromboembolic events, diarrhoea and worsening of chronic renal failure). Cytopenia (40, 17.3%), diarrhoea (15, 6.5%), asthenia (9, 3.9%) and neuropathy (6, 2.6%) were the most frequent ADRs. All ADRs were severe, 10 (6 patients) had been poorly described or were unknown and only 9 (5 patients) had been reported by spontaneous notification. CONCLUSIONS Valuable information regarding severe and unknown ADRs was obtained from the RPT. Such registers are useful tools to complement spontaneous ADR notifications.

Abstract
Abstract
A collaborative study was conducted to validate a method for the determination of glyphosate and aminomethylphosphonic acid (AMPA) in crops. The analytes are extracted from crops with water, and the crude extracts are then subjected to a cation exchange cleanup. The analytes are derivatized by the direct addition of the aqueous extract into a mixture of heptafluorobutanol and trifluoroacetic anhydride. The derivatized analytes are quantitated by capillary gas chromatography with mass-selective detection (MSD). The collaborative study involved 13 laboratories located in 5 countries 12 laboratories returned valid data sets. The crops tested were field corn grain, soya forage, and walnut nutmeat at concentrations of 0.050, 0.40, and 2.0 mg/kg. The study used a split-level pair replication scheme with blindly coded laboratory samples. Twelve materials were analyzed, including 1 control and 3 split-level pairs for each matrix, 1 pair at each nominal concentration. For glyphosate, the mean recovery was 91%, the average intralaboratory variance, the repeatability relative standard deviation (RSDr), was 11%, and the interlaboratory variance, the reproducibility relative standard deviation (RSDR), was 16%. For AMPA, the mean recovery was 87%, the RSDr was 16%, and the RSDR was 25% at mg/kg levels.

Abstract
The aims of this retrospective cohort study were to retrieve characteristics and outcomes of older (65+) medical patients who are directly admitted to ICU from the ED and to compare these with those admitted to ICU from a ward. Of 1396 patients, 21 (1.5%) were directly admitted to ICU and 54 (3.9%) after a delay. Blood pressure was lower and respiratory rate higher in the direct than in the delayed group. The direct group had lower mortality (28-day: 19.0 vs. 38.9%, p=0.14; 1-year: 42.9 vs. 66.7%; p=0.06), shorter length-of-stay and returned more frequently to independent living than the delayed group. Only a fraction of older patients are admitted to ICU; directly admitted patients tend to have better outcomes.

Abstract
Defects in monolayer transition-metal dichalcogenides (TMDCs) may lead to unintentional doping, charge-carrier trapping, and nonradiative recombination. These effects impair electronic and optoelectronic technologies. Here we show that charged defects in MoS2 monolayers can be effectively screened when they are in contact with an ionic liquid (IL), leading to an increase in photoluminescence (PL) yield by up to two orders of magnitude. The extent of this PL enhancement by the IL correlates with the brightness of each pretreated sample. We propose the existence of two classes of nonradiative recombination centers in monolayer MoS2: (i) charged defects that relate to unintentional doping and may be electrostatically screened by ILs and (ii) neutral defects that remain unaffected by the presence of ILs.

Abstract
Background Biotechnological agents (BA) are increasingly being used in clinical practice. We aimed to determine, whether enquiries about them to a therapeutic consultation service have also become more frequent, and to describe the information requested in these consultations. Methods We retrospectively reviewed 14 104 therapeutic consultations collected in a computerised database between 2000 and 2014. Enquiries about BA (monoclonal antibodies, fusion proteins or cytokine antagonists) were chosen. Information on the type of BA, underlying condition, type of enquiry and affiliation of the enquirer was retrieved and compared with data from consultations about other agents. Results During the study period, 365 enquiries about 30 different BA were received. Only 4% of them were received before 2004, while 48.8% were received after 2010. Rituximab, infliximab, adalimumab and etanercept were most frequently enquired about. Agent selection (n=184) and/or adverse effects (n=174) were the most frequent reasons for making an enquiry. Most enquiries about an agent selection were made about an off-label use (n=164), mainly for systemic autoimmune diseases (n=61). Over half of the enquiries about adverse effects were about their teratogenic potential (n=96). Enquiries about BA more often requested an opinion (87.7% vs 77.7%) were made by physicians (89.9% vs 76.9%), from a hospital (81.6% vs 44.5%) and regarded a specific patient (87.4% vs 74.5%). Conclusions Therapeutic consultations about BA are increasing. Most of them are related to uncertainties of health professionals regarding any new medicine: their off-label use, actual adverse effects or the teratogenic potential of the involved agents.

Abstract
BACKGROUND As HIV management has become more successful during the past years, non-communicable diseases have become more prevalent among HIV-infected individuals. As a result, more HIV-infected patients die of cardiovascular diseases, with diabetes being one of the main risk factors. This study evaluates screening and management of diabetes among HIV-infected patients in a university hospital in the Netherlands. METHODS We examined clinical characteristics, glycaemic control and cardiovascular risk management of HIV-infected patients with coexisting diabetes, and determined the frequency of diabetes screening in those without. RESULTS Of 518 HIV-infected patients, 28 had been diagnosed with diabetes (5.4%), mostly (20÷28) after being diagnosed with HIV. Patients with coexisting diabetes were older, had a longer duration of HIV, lower CD4 cell counts and higher body mass index (BMI), and were more likely to use aspirin, statins and antihypertensive medication than those without diabetes (all p < 0.05). HbA1c values were below 7% (53 mmol÷mol) in 54% of patients. Targets for systolic blood pressure (< 140 mmHg), LDL cholesterol (< 2.5 mmol÷l) and BMI (< 25 kg÷m2) were achieved by 82%, 50% and 29% of patients, respectively. Annual ophthalmology examination, screening for microalbuminuria and foot control were rarely performed. Among the patients without known diabetes, diabetes screening during the past year had been performed using (non-fasting) plasma glucose in 56% and HbA1c in 10%, but 42% of patients had not been screened. CONCLUSION For HIV-infected individuals with diabetes, glycaemic control and cardiovascular risk management were reasonable, but screening for microvascular complications was rarely performed. Annual diabetes screening of HIV-infected patients was not routine.

Abstract
The gold standard for evaluating cognitive impairments in HIV-infected patients is to administer an extensive neuropsychological assessment. This may, however, be time-consuming and hence not always feasible in the clinic. Therefore, several brief screening tools have been developed. This study determined the validity of the Montreal Cognitive Assessment (MoCA) and the HIV Dementia Scale (HDS) in detecting cognitive impairment using both the Frascati and cognitive impairment, no dementia (CIND) criteria to classify cognitive impairment in HIV-1 infected patients. The MoCA, HDS, and an extensive neuropsychological assessment, covering nine cognitive domains, were administered in a group of 102 HIV-infected patients who were all on cART and virologically suppressed for at least 1 year. Results show that the areas under the curve (AUCs) for both the MoCA and the HDS were statistically significant, using both the Frascati and the CIND criteria as gold standard. However, the AUCs for the MoCA and HDS did not differ significantly, regardless of the used classification criteria (Frascati: z = 0.37, p = 0.35; CIND: z = -0.62, p = 0.27). Sensitivity of both the MoCA and HDS were low for the recommended cutoff scores (Frascati: MoCA (<26) = 0.56, HDS (<11) = 0.26; CIND: MoCA (<26) = 0.55, HDS (<11) = 0.36). Cutoff scores with good sensitivity and adequate specificity could not be determined for both screening instruments. Therefore, the HDS and MoCA are not recommended as sole instruments to diagnose HIV-associated cognitive impairment.

Abstract
BACKGROUND Hypercholesterolaemia plays a key role in the development and progression of coronary artery disease. There are numerous drugs available to treat this condition but they are often expensive and can have unwanted side effects. Therefore, a screening of lactic acid bacteria to select candidate probiotic strains to reduce cholesterol levels was carried out. Three Lactobacillus plantarum strains (CECT 7527, 7528 and 7529) were selected as potential probiotics to reduce cholesterol levels after conducting several in vitro tests for demonstrating the functionalities of the strains according to international guidelines. RESULTS The three strains showed a high ability to survive under gastrointestinal tract conditions and to adhere to intestinal cells. Regarding lipid metabolism, the strains showed a great production of bile salt hydrolase, especially when combined. Moreover, the strains assimilated cholesterol directly from the medium. Part of the cholesterol present in the medium was removed via binding onto the bacterial cellular surface. Finally, the three strains, especially CECT 7529, produce large quantities of propionic and butyric acids. CONCLUSION Combined, these characteristics suggest that these strains could be excellent candidates for reducing high blood cholesterol levels.

Abstract
OBJECTIVE The effectiveness of influenza vaccination in preventing illness is lower in the elderly; this is why the ability of Lactobacillus plantarum CECT 7315/7316 to stimulate the response to influenza vaccination in elderly was evaluated. RESEARCH METHODS AND PROCEDURES A randomized, double-blind, placebo-controlled human trial including 60 institutionalized volunteers aged 65-85 years was performed. All the volunteers were vaccinated with a trivalent influenza vaccine (A/Wisconsin/67/2005 NYMC X-161B (H3N2), A/Solomon Islands/3/2006 (H1N1) and B/Malaysia/2506/2004) for the Spanish vaccine campaign 2006/2007. The consumption of the probiotic began between three and four months after the vaccination. Volunteers were randomly assigned to one of three following groups: group A (receiving 5*10(9) cfu/day of L. plantarum CECT 7315/7316 in 20 g powdered skim milk), group B (receiving 5*10(8) cfu/day of L. plantarum CECT 7315/7316 in 20 g powdered skim milk) and group C or placebo (20 g powered skim milk). The participants consumed the probiotic during 3 months. RESULTS The consumption of L. plantarum CECT 7315/7316 during 3 months after influenza vaccination increased the levels of influenza-specific IgA and IgG antibodies. Moreover, a trend towards an increase in influenza-specific IgM antibodies was also observed. CONCLUSION L. plantarum CECT7315/7316 has an immunostimulating effect and could be used to improve the response to influenza vaccination in elderly.

Abstract
Background Ancestral reconstructions of mammalian genomes have revealed that evolutionary breakpoint regions are clustered in regions that are more prone to break and reorganize. What is still unclear to evolutionary biologists is whether these regions are physically unstable due solely to sequence composition and/or genome organization, or do they represent genomic areas where the selection against breakpoints is minimal. Methodology and Principal Findings Here we present a comprehensive study of the distribution of tandem repeats in great apes. We analyzed the distribution of tandem repeats in relation to the localization of evolutionary breakpoint regions in the human, chimpanzee, orangutan and macaque genomes. We observed an accumulation of tandem repeats in the genomic regions implicated in chromosomal reorganizations. In the case of the human genome our analyses revealed that evolutionary breakpoint regions contained more base pairs implicated in tandem repeats compared to synteny blocks, being the AAAT motif the most frequently involved in evolutionary regions. We found that those AAAT repeats located in evolutionary regions were preferentially associated with Alu elements. Significance Our observations provide evidence for the role of tandem repeats in shaping mammalian genome architecture. We hypothesize that an accumulation of specific tandem repeats in evolutionary regions can promote genome instability by altering the state of the chromatin conformation or by promoting the insertion of transposable elements.

Abstract
UNLABELLED Probiotics have been proven effective for preventing caries. In contrast, the effect of probiotics on improving oral diseases such as gingivitis, periodontitis and halitosis has been less explored. OBJECTIVE To perform a screening of lactic acid bacteria, according to international guidelines for the evaluation of probiotics, in order to select candidate probiotic strains for preventing oral disorders. STUDY DESIGN The strains were isolated from healthy children and were subjected to a variety of in vitro tests in order to show their functionality. The safety of the strains was assessed by determining antibiotic susceptibility and production of lactic acid. RESULTS Forty-six of the 100 new isolates were assigned to lactic acid bacteria genera after a biochemical characterization. Most of the new isolated strains seem to be resistant to oral conditions, have great ability to form aggregates and have high antagonistic activity against oral pathogens. None of the strains produced unpleasant volatile compounds. The strains showed high ability to adhere to oral tissues and they do not present any antibiotic resistance. Moreover, an increased risk of developing caries due to their ability to produce lactic acid was discarded in seven pre-selected probiotic candidates. CONCLUSIONS These lactic acid bacteria show promising properties to be used as potential probiotics for improving oral health.

Abstract
Obesity and metabolic syndrome (MS) occur frequently in patients with obstructive sleep apnoea syndrome (OSAS). We hypothesised that circulating free fatty acids (FFAs) are elevated in OSAS patients independently of obesity. This elevation may contribute to the development of MS in these patients. We studied 119 OSAS patients and 119 controls. Participants were recruited and studied at sleep unit of our institution (Hospital Universitari Son Dureta, Palma de Mallorca, Spain) and were matched for sex, age and body mass index (BMI). The occurrence of MS was analysed by clinical criteria. Serum levels of FFAs, glucose, triglycerides, cholesterol, high-density lipoprotein-cholesterol, aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, C-reactive protein and 8-isoprostanes were determined. Prevalence of MS was higher in OSAS than in the control group (38 versus 21%; p=0.006). OSAS patients had higher FFAs levels than controls (mean±sd 12.2±4.9 versus 10.5±5.0 mg·dL(-1); p=0.015). Among subjects without MS, OSAS patients (OSAS+ MS-) showed higher levels of FFAs than controls (OSAS- MS-) (11.6±4.7 versus 10.0±4.4 mg·dL(-1); p=0.04). In a multiple regression model, after adjustment for age, sex, BMI and the presence of MS, FFAs were significantly associated with apnoea/hypopnoea index (p=0.04). This study shows that FFAs are elevated in OSAS and could be one of the mechanisms involved in the metabolic complications of OSAS.

Abstract
Although their function has not yet been clearly elucidated, interstitial telomeric sequences (ITSs) have been cytogenetically associated with chromosomal reorganizations, fragile sites, and recombination hotspots. In this paper, we show that ITSs are not located at the exact evolutionary breakpoints of the inversions between human and chimpanzee and between human and rhesus macaque chromosomes. We proved that ITSs are not signs of repair in the breakpoints of the chromosome reorganizations analyzed. We found ITSs in the region (0.7-2.7 Mb) flanking one of the two breakpoints in all the inversions assessed. The presence of ITSs in those locations is not by chance. They are short (up to 7.83 repeats) and almost perfect (82.5-97.1% matches). The ITSs are conserved in the species compared, showing that they were present before the reorganizations occurred.

Abstract
Backgound The RPS4 gene codifies for ribosomal protein S4, a very well-conserved protein present in all kingdoms. In primates, RPS4 is codified by two functional genes located on both sex chromosomes: the RPS4X and RPS4Y genes. In humans, RPS4Y is duplicated and the Y chromosome therefore carries a third functional paralog: RPS4Y2, which presents a testis-specific expression pattern. Results DNA sequence analysis of the intronic and cDNA regions of RPS4Y genes from species covering the entire primate phylogeny showed that the duplication event leading to the second Y-linked copy occurred after the divergence of New World monkeys, about 35 million years ago. Maximum likelihood analyses of the synonymous and non-synonymous substitutions revealed that positive selection was acting on RPS4Y2 gene in the human lineage, which represents the first evidence of positive selection on a ribosomal protein gene. Putative positive amino acid replacements affected the three domains of the protein: one of these changes is located in the KOW protein domain and affects the unique invariable position of this motif, and might thus have a dramatic effect on the protein function. Conclusion Here, we shed new light on the evolutionary history of RPS4Y gene family, especially on that of RPS4Y2. The results point that the RPS4Y1 gene might be maintained to compensate gene dosage between sexes, while RPS4Y2 might have acquired a new function, at least in the lineage leading to humans.

Abstract
Different strategies have been developed to produce vaccines against Pasteurella multocida. The approach described herein involves overexpression on the bacterial cell surface of Fur-regulated IROMPs (iron-regulated outer-membrane proteins). Accordingly, the ability of fur mutants to promote heterologous protection was examined in a Swiss mouse animal model. Twofur mutants derived from P. multocida were isolated, one of which was also defective in the OmpH protein. In mice challenged with virulent P. multocida, outer-membrane protein (OMP) extracts of fur cells conferred the same protection as obtained with wild-type cells grown in iron-depleted medium. Total protection was achieved with 40 microg of OMP extract from the fur ompH mutant. Mice administered heat-inactivated fur ompH cells were 60% cross-protected. The presence of a galE mutation in these cells did not further increase the protection level. Additionally, cell disruption by sonication provoked a higher level of protection than conferred by heat-treated cells. Taken together, the results showed that P. multocida fur ompH cells offer a simple and suitable approach for cross-protecting animals against infection with P. multocida.

Abstract
The Spire protein, together with the formin Cappuccino and profilin, plays an important role in actin-based processes that establish oocyte polarity. Spire contains a cluster of four actin-binding WH2 domains. It has been shown to nucleate actin filaments and was proposed to remain bound to their pointed ends. Here we show that the multifunctional character of the WH2 domains allows Spire to sequester four G-actin subunits binding cooperatively in a tight SA(4) complex and to nucleate, sever, and cap filaments at their barbed ends. Binding of Spire to barbed ends does not affect the thermodynamics of actin assembly at barbed ends but blocks barbed end growth from profilin-actin. The resulting Spire-induced increase in profilin-actin concentration enhances processive filament assembly by formin. The synergy between Spire and formin is reconstituted in an in vitro motility assay, which provides a functional basis for the genetic interplay between Spire, formin, and profilin in oogenesis.

Abstract
Recent studies reveal that multisensory convergence can occur in early sensory cortical areas. However, the behavioral importance of the multisensory integration in such early cortical areas is unknown. Here, we used c-Fos immunohistochemistry to explore neuronal populations specifically activated during the facilitation of reaction time induced by the temporally congruent audiovisual stimuli in rats. Our newly developed analytical method for c-Fos mapping revealed a pronounced up-regulation of c-Fos expression particularly in layer 4 of the lateral secondary visual area (V2L). A local injection of a GABA A receptor agonist, muscimol, into V2L completely suppressed the audiovisual facilitation of reaction time without affecting responses to unimodal stimuli. Such a selective suppression was not found following the injection of muscimol into the primary auditory and visual areas. To examine whether or not the rats might have shown the facilitated responses because of increment of stimulus intensity caused by the two modal stimuli, the behavioral facilitation induced by the high-intensity unimodal stimuli was tested by the injection of muscimol into V2L, which turned out not to affect the facilitation. These results suggest that V2L, an early visual area, is critically involved in the multisensory facilitation of reaction time induced by the combination of auditory and visual stimuli.

Abstract
BACKGROUND Excessive daytime sleepiness (EDS) occurs often in patients with obstructive sleep apnea syndrome (OSAS). However, not all patients present EDS. We hypothesized that the prostaglandin D2 system (PGD2) may be involved in the pathogenesis of EDS associated with OSAS. METHODS We measured the levels of lipocalin-type PGD synthase (L-PGDS), the enzyme that produces PGD2, in the serum of 47 patients with OSAS (26 with and 21 without EDS) and 18 healthy controls. RESULTS Patients with EDS had higher levels of L-PGDS (0.73+/-0.06 mg/L) than patients without EDS (0.58+/-0.03 mg/L, p<0.05) and controls (0.62+/-0.02 mg/L, p<0.05). L-PGDS levels in patients without EDS and controls were similar. CONCLUSION The increased levels of circulating L-PGDS detected in OSAS patients with EDS suggest a possible role of the prostaglandin D system in the pathophysiology of daytime sleepiness in these patients.

Abstract
2021 Background: Standard therapy for glioblastoma, which includes surgery followed by radiation and concurrent chemotherapy, creates a low tumor burden environment that could be ideal for immunotherapeutic approaches. We conducted a Phase I study to assess the safety and immunologic responses of tumor lysate-pulsed dendritic cell (DC) therapy plus topical imiquimod, in combination with standard radio-chemotherapy. Methods: Thirteen patients with newly diagnosed glioblastoma were immunized using autologous tumor lysate-pulsed DC. Each patient initially received 3 immunizations at 2-week intervals, following completion of a 6-week course of radio- chemotherapy. Four patients received 1 million DC, 4 received 5 million, and 5 received 10 million DC per immunization. Patients without tumor progression subsequently received booster vaccinations combined with topical administration of the TLR-7 agonist imiquimod. Immunologic responses to tumor antigens were monitored by HLA-restricted tetramer staining, CTL assays, and quantitation of T-regulatory cells. Clinical tumor growth was monitored by brain MRI scans every 2 months, and the primary clinical endpoint was 2-year survival. Results: All immunizations were well tolerated, with only mild side effects attributable to the DC vaccination and imiquimod adjuvant. Increased levels of CD8+ T cells reactive against tumor antigens, (e.g., gp100, TRP-2, her-2, survivin, and CMV antigens), were detected in 5 patients. Median PFS and OS have not been reached in this trial. To date, 6 of the 13 patients have progressed, and 4 of those have died. The median PFS to date is 18.1 mos. and median OS is 33.8 mos. This compares favorably with controls from the published literature, with a median PFS of 6.9 mos and OS of 14.6 mos. Conclusions: This study demonstrates the safety and clinical/immunologic effects of an autologous tumor lysate-pulsed DC vaccine for patients with newly diagnosed glioblastoma. The adjunctive use of the TLR-7 agonist imiquimod with DC vaccination appears to be non-toxic, and deserves further study. We demonstrate that this active immunotherapy strategy can generate antigen-specific immunologic responses in brain tumor patients following standard radio-chemotherapy. No significant financial relationships to disclose.

Abstract
Onconase is an RNase with a very specific property because it is selectively toxic to transformed cells. This toxin is thought to recognize cell surface receptors, and the protection conferred by metabolic poisons against Onconase toxicity indicated that this RNase relies on endocytic uptake to kill cells. Nevertheless, its internalization pathway has yet to be unraveled. We show here that Onconase enters cells using AP-2/clathrin-mediated endocytosis. It is then routed, together with transferrin, to the receptor recycling compartment. Increasing the Onconase concentration in this structure using tetanus toxin light chain expression enhanced Onconase toxicity, indicating that recycling endosomes are a key compartment for Onconase cytosolic delivery. This intracellular destination is specific to Onconase because other (and much less toxic) RNases follow the default pathway to late endosomes/lysosomes. Drugs neutralizing endosomal pH increased Onconase translocation efficiency from purified endosomes during cell-free translocation assays by preventing Onconase dissociation from its receptor at endosomal pH. Consistently, endosome neutralization enhanced Onconase toxicity up to 100-fold. Onconase translocation also required cytosolic ATP hydrolysis. This toxin therefore shows an unusual entry process that relies on clathrin-dependent endocytic uptake and then neutralization of low endosomal pH for efficient translocation from the endosomal lumen to the cytosol.
