Abstract
The isolation of Campylobacter fetus subsp. venerealis (Cfv) from clinical samples is the gold standard for confirming cases of bovine genital campylobacteriosis, an important cause of infertility in cattle and a potential public health concern. Furthermore, isolation is also necessary for the development of autologous vaccines, characterization of strains for antimicrobial susceptibility patterns, etc. Nevertheless, the sensitivity of culture methods is usually low, and there is no standardized protocol to maximize the recovery of Cfv from clinical samples. The aim of the current study is to design a protocol for the culture of Cfv from preputial samples by evaluating the combination of different transport, enrichment and culture media considering the impact of certain factors (time between collection and enrichment, temperature, and use of filters). The use of modified Lander's transport medium and storing the sample for 24 h at 21 ± 2 °C led to the highest recovery of Cfv CFUs. In contrast, the storage of the samples during 24-48 h in PBS and Thomann rarely allowed the recovery of Cfv regardless of the temperature. The enrichment medium yielding the best results was Preston (significantly higher recovery than Brucella medium), while Cfv could not be isolated with Bolton. Regarding our diagnostic assay (using Lander as transport medium and Preston as enrichment medium), the best protocol in terms of maximizing Cfv recovery as well as limiting contaminations is to culture the samples in i) solid media Preston or Skirrow, and ii) using 0.65 μm filters and incubating plates at 37 °C in microaerophilic conditions.

Abstract
There is a knowledge gap in the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) causing bloodstream infections (BSIs) in Peru. Through a surveillance study in 13 hospitals of 10 Peruvian regions (2017-2019), we assessed the proportion of MRSA among S. aureus BSIs as well as the molecular typing of the isolates. A total of 166 S. aureus isolates were collected, and 36.1% of them were MRSA. Of note, MRSA isolates with phenotypic and genetic characteristics of the hospital-associated Chilean-Cordobes clone (multidrug-resistant SCCmec I, non-Panton-Valentine leukocidin [PVL] producers) were most commonly found (70%), five isolates with genetic characteristics of community-associated MRSA (CA-MRSA)-SCCmec IV, PVL-producer-(8.3%) were seen in three separate regions. These results demonstrate that hospital-associated MRSA is the most frequent MRSA found in patients with BSIs in Peru. They also show the emergence of S. aureus with genetic characteristics of CA-MRSA. Further studies are needed to evaluate the extension of CA-MRSA dissemination in Peru.

Abstract
Only up to 25% of the cases in which there is a familial aggregation of breast and/or ovarian cancer are explained by germline mutations in the well-known BRCA1 and BRCA2 high-risk genes. Recently, the BRCA1-associated ring domain (BARD1), that partners BRCA1 in DNA repair, has been confirmed as a moderate-risk breast cancer susceptibility gene. Taking advantage of next-generation sequencing techniques, and with the purpose of defining the whole spectrum of possible pathogenic variants (PVs) in this gene, here we have performed a comprehensive mutational analysis of BARD1 in a cohort of 1946 Spanish patients who fulfilled criteria to be tested for germline pathogenic mutations in BRCA1 and BRCA2. We identified 22 different rare germline variants, being 5 of them clearly pathogenic or likely pathogenic large deletions, which account for 0.26% of the patients tested. Our results show that the prevalence and spectrum of mutations in the BARD1 gene might vary between different regions of Spain and expose the relevance to test for copy number variations.

Abstract
BACKGROUND There is scarce information detailing clinical and physiological effects of reversible injectable protocols of chemical restraint on Neotropical primates. METHODS Nineteen captive Spix´s Owl monkeys (Aotus vociferans) were assessed in a double-blind randomized crossover study using the following: ketamine/xylazine [KX], ketamine/midazolam [KM] and ketamine/xylazine/midazolam [KXM]. During immobilization, respiratory and pulse rates, rectal temperature, haemoglobin oxygen saturation and arterial blood pressure were recorded at 5-minute intervals during a 20-minute period; afterwards, antagonist drugs (yohimbine for xylazine and flumazenil for midazolam) were, respectively, administered. Quality and duration of induction, immobilization and recovery periods were recorded. RESULTS Ketamine/xylazine increased manipulation sensitivity and produced poor muscle relaxation. KM maintained all assessed parameters within physiological ranges. KXM produced depressant cardiorespiratory effects and hypotension. All protocols produced hypothermia. CONCLUSIONS Based on its adequate anaesthetic depth and minimum effects on physiological parameters, KM is suitable for immobilizing A vociferans and performing short-term procedures lasting around 20 minutes.

Abstract
BACKGROUND Some chronic inflammatory skin diseases, such as psoriasis, have been associated with an increased prevalence of non-alcoholic fatty liver disease (NAFLD). Nevertheless, this prevalence in hidradenitis suppurativa (HS) has not been assessed to date. OBJECTIVES To determine the prevalence of NAFLD in patients with HS and the risk factors associated with this disorder. METHODS This case-control study enrolled 70 HS patients and 150 age- and gender-matched controls who were evaluated by hepatic ultrasonography (US) and transient elastography (TE) after excluding other secondary causes of chronic liver disease. The diagnosis of NAFLD was established if US and/or TE were altered. RESULTS The prevalence of NAFLD was significantly increased in patients with HS compared to controls (72.9% vs. 24.7%: P < 0.001). In the multivariable regression model adjusted for age, sex and classic metabolic risk factors for NAFLD, HS was significantly and independently associated with the presence of NAFLD [OR 7.75 confidence interval (CI) 2.54-23.64; P < 0.001]. CONCLUSIONS Our results show a high prevalence of NAFLD in HS patients independent of classic metabolic risk factors. Therefore, we suggest HS patients to be evaluated for NAFLD and managed accordingly.

Abstract
Detailed information on the anaesthetic and cardiorespiratory effects of drug combinations used for the chemical immobilization of Kinkajous (Potos flavus) is scarce. This study assessed the effects of ketamine (2.5mg/kg), xylazine (1mg/kg) and midazolam (0.5mg/kg) combination in P. flavus. Five clinically healthy adult Kinkajous of both sexes were included. Heart rate, respiratory rate, oxygen saturation, blood pressure and body temperature were recorded at five-minute intervals for 25 minutes. Then, animals received 0.125mg/kg of yohimbine by intramuscular injection. Anaesthetic depth was assessed based on stimulus response and muscle tone. Induction, immobilization, and recovery periods were recorded and qualitatively assessed based on the absence of adverse effects. The durations of the induction, immobilization, and recovery periods were 9.42±1.73, 33.33±2.16, and 31.37±5.82 minutes. All periods showed good quality and adequate anaesthetic depth was achieved. Mean heart and respiratory rates were 99±20 beats/minute and 44±9 breaths/minute. Both parameters decreased over the duration of the anaesthesia but they did not reach levels suggesting either bradycardia or bradypnea. Mean body temperature was 37.1±1.5 0C and it also showed a decreasing trend over the duration of the anaesthesia. Mean oxygen saturation was 92±6% and it showed a mildly increasing trend over the duration of the anesthesia. Mean blood pressure was 129±23 mmHg and mild to moderate hypertension was observed. No mortality occurred and no adverse effects were observed in any of the individuals during the three months following immobilization. The assessed anaesthetic combination effectively immobilized the P. flavus individuals, provided good quality and acceptable duration of both induction and recovery periods. It should, however, not be used in Kinkajous with either known hypertension record or pre-existing target organ disease (e.g., renal failure, retinopathy).

Abstract
El trauma psíquico es una transversalidad en la historia de la humanidad, pero de diagnóstico tardío, especialmente en lo que refiere a su incorporación a los sistemas de clasificación en psicopatología como Trastorno por Estrés Postraumático (TEPT). Desde ese momento hasta nuestros días han ido en aumento los estudios sobre TEPT, avanzando primero en las formas de evaluación específica y posteriormente en las propuestas de intervención, con énfasis en población adulta. Otros trabajos han evidenciado que, la semiológica del TEPT en niños y adolescentes, no puede ser analizada y bordada de igual manera que en población adulta. En este artículo se presentan los resultados generales de estudios sobre el TEPT en la infancia y adolescencia y los trabajos sobre un Listado de apoyo a los Clínicos para la evaluación del TEPT y del TEPTC o DESNOS, con algunos de los resultados preliminares de los estudios realizados con población de menores en situación de abuso y maltrato.

Abstract
BACKGROUND Skin problems are among the most frequent reasons for seeking medical attention in primary care. In recent years, as a result of the process of adapting medical curricula to the requirements of the European Higher Education Area, the amount of time students spend learning the concepts of dermatology has been reduced in many universities. MATERIAL AND METHODS In order to reach a consensus on core content for undergraduate education in dermatology, we sent a survey to the 57 members of the instructors' group of the Spanish Academy of Dermatology and Venereology (AEDV), asking their opinions on what objectives should be set for a dermatology course in Spain. A total of 131 previously selected objectives were listed. We then applied the Delphi method to achieve consensus on which ones the respondents considered important or very important (score≥4 on a Likert scale). RESULTS Nineteen responses (33%) were received. On the second round of the Delphi process, 68 objectives achieved average scores of at least 4. The respondents emphasized that graduates should understand the structure and functions of the skin and know about bacterial, viral, and fungal skin infections, the most common sexually transmitted diseases (STDs), and the 4 main inflammatory dermatoses. Students should also learn about common complaints, such as itching and bald patches; the management of dermatologic emergencies; purpura and erythema nodosum as signs of internal disease; and the prevention of STDs and skin cancer. During clinical clerkships students should acquire the communication skills they will need to interview patients, write up a patient's medical history, and refer the patient to a specialist. CONCLUSIONS The AEDV's group of instructors have defined their recommendations on the core content that medical faculties should adopt for the undergraduate subject of dermatology in Spain.

Abstract
The helminth parasite Fasciola hepatica causes fascioliasis in human and domestic ruminants. Economic losses due to this infection are estimated in U$S 2000-3000 million yearly. The most common method of control is the use of anthelmintic drugs. However, there is an increased concern about the growing appearance of F. hepatica resistance to Triclabendazole (TCBZ), an anthelmintic with activity over adult and young flukes. F. hepatica has eight Glutathione S-Transferase (GST) isozymes, which are enzymes involved in the detoxification of a wide range of substrates through chemical conjugation with glutathione. In the present work we identified and characterized the GST mu gene isolated from the TCBZ-susceptible and TCBZ-resistant F. hepatica strains. Total RNA was transcribed into cDNA by reverse transcription and a 657 bp amplicon corresponding to the GST mu gene was obtained. The comparative genetic analysis of the GST mu gene of the TCBZ susceptible strain (Cullompton) and TCBZ resistant strain (Sligo) showed three nucleotide changes and one amino acid change at position 143 in the GST mu isozyme of the TCBZ-resistant strain. These results have potential relevance as they contribute better understand the mechanisms that generate resistance to anthelmintics.

Abstract
BACKGROUND A significant increase in the number of patients starting chronic hemodialysis (HD) with an estimated glomerular filtration rate (eGFR)≥10 mL/min/1.73 m(2) was observed in Argentina between 2004 and 2009. METHODS In order to study this topic, we calculated the mortality hazard ratios (HR) in a cohort of incident HD individuals from the Argentine Registry of Chronic Dialysis [Registro Argentino de Diálisis Crónica] (2004-2009), grouped according to the initial eGFR (0-4.9, 5-9.9, 10-14.9 and ≥15 mL/min/1.73 m(2) ; reference group 0-4.9) estimated by CKD-EPI; in three cohorts: "total population", "healthy" (<65 years, without diabetes or comorbidities) and "planned entry" (with permanent vascular access). RESULTS After adjusting the population (n=16,931) for age, gender, coexisting conditions, serum albumin, income, and temporary vascular access a HR of 1.19 (95%CI:1.07-1.33) was observed in the group with eGFR≥15 mL/min/1.73 m(2). In the cohort of 3,897 "healthy" after adjusting for the same co-variates, HRs of 1.44 (95%CI: 1.08-1.65) and 1.65 (95%CI: 1.06-2.55) were obtained for the groups with baseline eGFR values of 10-14.9 and ≥15 mL/min/1.73 m(2), respectively. In "planned entry" patients (n=6,280), after adjusting for age, gender, co-morbidities, serum albumin and income, HRs in all groups were not significantly different as compared to the control group. CONCLUSIONS HD initiation with eGFR>10 mL/min/1.73 m(2) shows no survival advantage. The higher mortality in the group with >eGFR starting dialysis looks like an "artifact" related to higher age, more co-morbidities, low albuminemia and the use of temporary vascular access.

Abstract
The first European case of tetrodotoxin intoxication is reported in a patient who ingested a trumpet shellfish from the Atlantic Ocean in Southern Europe. He suffered general acute paralysis with respiratory failure necessitating ventilation. Early neurophysiologic studies showed complete peripheral nerve inexcitability, with no recordable sensory or motor responses, and normal electroencephalography. Tetrodotoxin was detected in high quantities in the patient's blood and urine through high performance liquid chromatography-mass spectrometry analysis. Seventy-two hours after admission the patient recovered normal strength, reflexes and sensation.

Abstract
Background: Although not definitively proven, there is commonly accepted to be a latitudinal gradient in the distribution of multiple sclerosis (MS), which is more frequent in temperate zones. The European Mediterranean countries are situated in a zone of median frequency, although ever increasing figures have been noted in the last decades. Objective: The objective of this study was to assess the current prevalence rate of MS in the province of Malaga, Southern Spain. Methods: The capture–recapture method (CRM) uses independent sources of data and permits the number of non-registered cases of a given disease to be estimated, and by doing so, to avoid ascertainment bias. Results: Use of this method showed the estimated prevalence rate of MS in the province of Malaga, Southern Spain, to be 125/105 (95% confidence interval: 102/105–169/105), higher than the figures published previously. Conclusions: Although we recognize that these data need to be confirmed in further studies and in other areas of the country using a similar method, we believe this study is the first to find such high figure of prevalence, being very similar to the figures reported in recent years in other southern European countries.

Abstract
We studied the role of Kupffer cell functioning in T3 liver preconditioning against ischemia-reperfusion (IR) injury using the macrophage inactivator gadolinium chloride (GdCl3) previous to T3 treatment. Male Sprague-Dawley rats given a single i.p. dose of 0.1 mg T3/kg were subjected to 1 h ischemia followed by 20 h reperfusion, in groups of animals pretreated with 10 mg GdCl3/kg i.v. 72 h before T(3) or with the respective vehicles. IR resulted in significant enhancement of serum aspartate aminotransferase (3.3-fold increase) and tumor necrosis factor-alpha (93% increase) levels, development of liver damage, and diminished nuclear factor-kappaB DNA binding over control values. These changes, which were suppressed by the T3 administration prior to IR, persisted in animals given GdCl3 before T3 treatment, under conditions of complete elimination of ED2+ Kupffer cells achieved in a time window of 72 h. It is concluded that Kupffer cell functioning is essential for T3 liver preconditioning, assessed in a warm IR injury model by hepatic macrophage inactivation.

Abstract
Multiple sclerosis (MS) is a disease supposedly of autoimmune origin, with reactivity directed against myelin antigens. From the neuropathological point of view, MS produces inflammation, demyelination and axonal and neuronal degeneration. Inflammatory phenomena are predominant in the initial phase of the disease, followed later by neurodegenerative processes. Over the last decade, early treatment, during the most inflammatory phase of the disease, has been considered the best strategy to treat MS. Accordingly, we decided to determine the periods of delay between the first symptoms and the time to the first medical visit, the time to referral to a specialised MS unit, the delay in undertaking clinical and paraclinical tests, the diagnostic criteria used and the overall delay in diagnosis and treatment. The median time from onset of first symptoms to the first visit to a physician was 19.2 months, which represented the greatest delay. The median time between this initial medical consultation and the confirmation of the diagnosis by a specialised MS unit was 5.7 months, and the overall time from symptom onset to diagnosis was 24.9 months (2.08 years). The median time between onset of the first symptoms and the decision to give the first treatment was 2 years. The most important delay was that from symptom onset to the first medical visit, with the other delays being less. Thus, it is during this initial period that greater effort is required in order to reduce the time to diagnosis, by increasing awareness of the problem of MS among the general population and primary care physicians.

Abstract
Between November 2003 and September 2006, 300 to 400 45-60-day-old Iberian piglets developed anorexia, polydipsia, and lethargy. Piglets were from 5 different farms in the western part of Spain. Morbidity was between 40% and 60%, and mortality ranged from 20% to 40% of the total population of postweaning piglets. In the 9 piglets in which postmortem examinations were conducted, kidneys were enlarged with yellow foci in the cortex and medulla. Microscopically, these foci were accumulations of crystals within the lumina of dilated distal tubules and collecting ducts, causing flattening of the renal tubular epithelial cells. The crystals displayed a multicolored birefringence under cross-polarized light. The multinucleated giant cells surrounding the crystals, interstitial fibrosis, and nonsuppurative infiltrates indicated a chronic inflammatory response. Toxicologic analysis of fixed kidney tissues from 4 piglets demonstrated the presence of melamine, ammeline, ammelide, and cyanuric acid. Ammelide concentrations were highest, ranging from 39,000 to 92,000 mg/kg, followed by ammeline (20,000-34,000 mg/kg), melamine (9,200-29,000 mg/kg), and cyanuric acid (2,200-9,100 mg/kg). The clinical, histologic, and toxicologic findings in affected piglets were similar to those reported in dogs and cats that died of melamine and melamine analogue-associated renal failure in 2004 and 2007. To the authors' knowledge, this is the first documented report of poisoning due to melamine and its analogues in pigs and demonstrates that contamination of pig feed occurred as early as 2003.

Abstract
BACKGROUND Lung cancer is one of the main health problems in the developed world. Our aims were to determine the symptomatic time prior to a specific diagnosis, the clinical and histological characteristics of the cases of lung cancer diagnosed in a department of internal medicine, and to analyze the survival factors. MATERIAL AND METHODS We studied retrospectively all patients diagnosed with lung cancer in the internal medicine department in the period between January 2001 and September 2006 reviewing clinical records. We specifically recorded age, gender, smoking habit, time and type of symptomatic presentation, radiological manifestations, methods of histological diagnosis, tumour staging, and performance status measured by ECOG classification. We also evaluated the factors associated with the survival time. RESULTS In this period 124 patients were diagnosed with lung cancer [mean age 68 +/-12 years, male 105 (85%), female 18 (15%), smokers 85%]. The mean symptomatic time before hospitalization was 74.5 +/-7 days. On hospitalization, respiratory symptoms were present in 40 (32%) patients. Tumour staging was carried out in 120 (97%) patients. In 96 (77%) patients non-small lung cancer was diagnosed, 62 (64%) in stage IV. In 28 (23%) patients small lung cancer was diagnosed, 22 (79%) in extended stage. Median time to diagnosis as an in-patient was 7 days. One hundred and thirteen (91%) patients died with a median survival time of 3 months. Factors associated with longer survival were the performance status and tumour stage. CONCLUSIONS In this community, lung cancer is diagnosed late and in advanced stages, with a high mortality rate. A better performance status and lower tumour stages appear to be associated with longer survival.

Abstract
The city of Bahía Blanca occupies a strategic place in Argentina south of the Pampean region in the north-east corner of the Patagonia. Since 1828, this city has been the historical and political border between Amerindian lands in the south, and the lands of European colonists. Nowadays, Bahía Blanca is an urban population mainly composed by descendents of immigrants from Spain and other European countries with apparently low admixture with Amerindians. In view of the unexpectedly high Amerindian admixture levels (about 46.7%) suggested by mtDNA data, and protein markers (19.5%), we analyzed a set of 19 Alu polymorphisms (18 autosomal, 1 of Chromosome Y) in a well-documented genealogical sample from Bahía Blanca. The genotyped sample was made up of 119 unrelated healthy individuals whose birth place and grandparent origins were fully documented. According to available genealogical records, the total sample has been subdivided into two groups: Bahía Blanca Original (64 individuals with all 4 gandparents born in Argentina) and Bahía Blanca Mix (55 individuals with one to three grandparents born out of Argentina). Allele frequencies and gene diversity values in Bahía Blanca fit well into the European ranges. Population relationships have been tested for 8 Alu markers, whose variation has been described in several Amerindian and European samples. Reynolds genetic distances underline the significant genetic similarity of Bahía Blanca to Europeans (mean distance 0.044) and their differentiation from Amerindians (0.146). Interestingly enough, when the general sample is divided, Bahía Blanca Original appears slightly closer to Amerindians (0.127) in contrast to Bahía Blanca Mix (0.161). Furthermore, the genetic relationships depicted through a principal components analysis emphasize the relative similarity of Bahía Blanca Original to Amerindians. A thorough knowledge of the sample origins has allowed us to make a subtle distinction of the genetic composition of Bahía Blanca.

Abstract
Vertebral osteomyelitis and septic arthritis are pathologies that principally affect people over fifty years old, but their incidence seems to be growing due to the increase of nosocomial bacteraemia associated with intravascular devices and the aging of hospitalised people. The majority of cases are produced by Staphylococcus aureus. We present the case and diagnostic process of a patient with vertebral osteomyelitis caused by another organism, Escherichia coli, with fatal evolution despite adequate treatment.

Abstract
The presence of pro-coagulant and anti-coagulant components of the placental vascular endothelium and syncytiotrophoblast are essential for homeostasis. Vascular endothelium prevents blood clot formation in vivo by involving a cell surface thrombin-binding glycoprotein, thrombomodulin (TM), that activates plasma anti-coagulant protein C. The TM levels increase during pregnancy, but the fibrinolytic capacity diminishes. Since vascular lesions with placental coagulation disorders can be associated with preeclampsia (PE), we hypothesized that TM expression in the stem villous vasculature and syncytiotrophoblast of the placenta are impaired in PE. Plasma and placental tissue samples were collected from PE (n=12) and normotensive pregnant patients (n=11). Patient's gestational age was 35.7+/-1.2 (normotensive) and 30.6+/-1.5 weeks (PE). Blood samples were drawn 30 min before delivery. Serum PAI-1 and PAI-2 antigens were determined by enzyme-linked immunoabsorbent assay (ELISA). A monoclonal antibody specific for TM was used for immunohistochemical tissue staining (ABC) and the staining was quantified by semi quantitative scores. Results show no intensity differences at the apical syncytiotrophoblast between the two groups. However, in preeclamptic placenta, TM expression diminished in the endothelium of the stem villi arteries and increased in the perivascular and stromal myofibroblats in cases of severe PE. TM changes were associated with an increased PAI-1/PAI-2 ratio. It is suggested that in severe PE, the decreased placental blood flow may be due to structural and functional impairment of the endothelium of the stem villi vessels and the surrounding perivascular and stromal myofibroblast, by increasing TM expression which may modulate fetal blow flow in the villous tree.

Abstract
The oil spill from Prestige tanker showed the importance of scientifically based protocols to minimize the impacts on the environment. In this work, we describe a new forecasting system to predict oil spill trajectories and their potential impacts on the coastal zone. The system is formed of three main interconnected modules that address different capabilities: (1) an operational circulation sub-system that includes nested models at different scales, data collection with near-real time assimilation, new tools for initialization or assimilation based on genetic algorithms and feature-oriented strategic sampling; (2) an oil spill coastal sub-system that allows simulation of the trajectories and fate of spilled oil together with evaluation of coastal zone vulnerability using environmental sensitivity indexes; (3) a risk management sub-system for decision support based on GIS technology. The system is applied to the Mediterranean Sea where surface currents are highly variable in space and time, and interactions between local, sub-basin and basin scale increase the non-linear interactions effects which need to be adequately resolved at each one of the intervening scales. Besides the Mediterranean Sea is a complex reduced scale ocean representing a real scientific and technological challenge for operational oceanography and particularly for oil spill response and search and rescue operations.

Abstract
OBJECTIVE To study the relationship between human leucocyte antigen (HLA) genotype and clinical response to interferon-beta (IFN-beta). METHODS We analysed the HLA class II genotypes of 96 multiple sclerosis (MS) patients treated with IFN-beta. The patients were classified as responders or non-responders according to clinical criteria: one or more relapses or a sustained increase after 1 year treatment compared with the year prior to IFN-beta therapy of > or = 0.5 points on the Expanded Disability Status Scale (EDSS). RESULTS There were 66 (69%) responders and 30 (31%) non-responders. Baseline clinical characteristics were similar. We found no association between HLA class II alleles and clinical response to IFN-beta. CONCLUSIONS HLA genotype does not appear to influence the clinical response to IFN-beta in MS patients.

Abstract
CHK1: gene encodes for a serine/threonine kinase involved in the regulation of cell cycle progression and DNA damage checkpoints. To determine the role of CHK1 in the pathogenesis of lymphoid neoplasms and its relationship to other DNA damage response genes, we have analyzed the gene status, protein, and mRNA expression in a series of tumors and nonneoplastic lymphoid tissues. CHK1 protein and mRNA expression levels were very low in both reactive tissues and resting lymphoid cells, whereas tumor samples showed a variable pattern of expression related to their proliferative activity. However, seven aggressive tumors showed a dissociate pattern of extremely low or negative protein expression in spite of a high proliferative activity. Four of these tumors were diffuse large B-cell lymphomas (DLCLs) with concordant reduced levels of mRNA, whereas one blastoid mantle cell lymphoma (B-MCL) and two DLCLs had relatively normal levels of mRNA. No gene mutations, deletions, or hypermethylation of the promoter region were detected in any of these cases. In all these tumors ATM, CHK2, and p53 genes were wild type. These findings suggest that CHK1 inactivation in NHLs occurs by loss of protein expression in a subset of aggressive variants alternatively to ATM, CHK2, and p53 alterations.

Abstract
Evidence for the effectiveness of immunosuppressive agents in MS is scanty. There are few good quality trials; most have methodological limitations, such as a small sample size and short duration. Moreover, there is no consistency in treatment regimes, patient groups or outcome measures and the clinical benefits remain unclear. Although azathioprine appears to reduce the relapse rate in MS patients, its effect on disability progression has not been demonstrated. Methotrexate may alter the course of disease favourably in patients with progressive MS, but the evidence is again sparse.

Abstract
Tacrolimus is an immunosuppressive drug used most successfully as a primary drug to suppress the rejection of transplants. Tacrolimus may also be useful as a novel therapy for autoimmune disease. There are various reports in the bibliography about the use of tacrolimus in the treatment of some autoimmune diseases: inflammatory bowel disease, autoimmune hepatitis, cutaneous, neurologic, renal, endocrine or eye disease. In this review of more than 130 papers, we discuss the rationale for the use of tacrolimus in autoimmune disease and report the clinical experience with the drug in the management of a variety of autoimmune diseases. But, although there are a lot questions that require future research (dose, duration of treatment, when to begin tacrolimus treatment, how to monitor it, etc.), there is also wide experience with tacrolimus in the treatment of this type of disease.

Abstract
The usage of alternative synonymous codons in the completely sequenced, extremely A+T-rich parasite Plasmodium falciparum was studied. Confirming previous studies obtained with less than 3% of the total genes recently described, we found that A- and U-ending triplets predominate but translational selection increases the frequency of a subset of codons in highly expressed genes. However, some new results come from the analysis of the complete sequence. First, there is more variation in GC3 than previously described; second, the effect of natural selection acting at the level of translation has been analysed with real expression data at 4 different stages and third, we found that highly expressed proteins increment the frequency of energetically less expensive amino acids. The implications of these results are discussed.

Abstract
BACKGROUND The human leukocyte antigen (HLA) class II DR2 haplotype (DRB1*1501, DQA1*0102, DQB1*0602) has been associated with multiple sclerosis (MS) in all ethnic groups and very strongly in Caucasians. AIM To investigate the possible HLA class II (DRB1, DQA1 and DQB1) associations with MS in Malaga, southern Spain. METHODS We analysed the HLA class II sub-regions DRB1, DQA1 and DQB1 by polymerase chain reaction (PCR) and sequence-specific oligonucleotide probe hybridization (PCR/SSO) for DRB1 and DQB1 and with sequence-specific primers (PCR/SSP) for DRB1 subtypes and DQA1. Possible HLA class II associations with clinical MS characteristics were investigated in 149 subjects with and 160 without MS. RESULTS Associations were detected between MS and the HLA class II alleles DRB1*1501 (45.6 % vs. 21.3%, p=0.001), DQA1*0102 (44% vs. 29.4%, p=0.001) and DQB1*0602 (45% vs. 20.6%, p=0.001). The DR2 haplotype (DRB1*1501, DQA1*0102, DQB1*0602) was associated with MS (43.6 % vs. 20%, p=0.002). DQB1*0602 was the only allele that maintained an association with MS in a logistic regression model. No HLA class II alleles or genotypes were significantly associated with any clinical characteristics of MS. CONCLUSIONS Our results confirm the positive association of the DR2 haplotype with MS, particularly the allele DQB1*0602, in the population studied. DR4 was not associated with the disease in Malaga. HLA class II alleles or haplotypes were not associated with clinical or demographic characteristics, or clinical form or severity of MS.

Abstract
The metabolic or insulin resistance syndrome, characterized by hypertension, dyslipidemia, glucose intolerance and hyperinsulinemia, may have genetic determinants. The insulin gene (INS), insulin receptor gene (INSR) and insulin receptor substrate 1 gene (IRS1) have been proposed as candidate genes. We examined eight polymorphisms in these genes in 163 individuals from Yucatan, Mexico; this population has a high prevalence of obesity, type 2 diabetes mellitus and dyslipidemia. Subjects were evaluated for body mass index (BMI) and blood pressure. Blood samples were collected to determine glucose, insulin, triglycerides and cholesterol levels, as well as for DNA isolation. Restriction fragment length polymorphisms in INS, INSR and IRS1 were identified by polymerase chain reaction and digestion with selected restriction enzymes. Among the eight polymorphisms analyzed, the PstI polymorphism in INS was significantly associated with hypertriglyceridemia and with the presence of at least one abnormality related to the metabolic syndrome (P=0.007 and 0.004, respectively). The MaeIII polymorphism in INS was associated with fasting hyperinsulinemia (P=0.045). In multilocus analyses including both INS polymorphisms, significant associations were seen with hypertriglyceridemia (P=0.006), hypercholesterolemia (P=0.031) and with presence of at least one metabolic abnormality (P=0.009). None of the polymorphisms in INSR or IRS1 was associated with any of these traits. These findings suggest that the insulin gene may be an important determinant of metabolic syndrome, and particularly of dyslipidemia, in this population.

Abstract
The authors describe a patient who presented with myoglobinuria after starting cerivastatin-gemfibrozil therapy. Muscle histochemistry revealed ragged-red fibers and cytochrome c oxidase negative (COX) fibers, and biochemistry showed a defect of COX activity. Immunoblot analysis showed a 60% reduction of COX I and COX II polypeptides. Cerivastatin myotoxicity might be related to a depletion of essential metabolites needed to anchor COX subunit I to mitochondrial membrane.
