Abstract
AIMS As diabetic retinopathy (DR) can occur even in well-controlled patients with type 2 diabetes (T2D), our study sought to determine whether it might be related to 'glucose memory' by evaluating patients' HbA1c over previous years and their skin autofluorescence (SAF). METHODS In 334 patients with T2D and HbA1c levels≤8%, their available values of HbA1c from previous years were collected, and their SAF measured by an advanced glycation end-product (AGE) reader. Binary logistic regression analysis was then used to correlate DR with previously recorded HbA1c levels and to SAF, with adjustment for DR risk factors [age, gender, BMI, duration of diabetes, arterial hypertension, diabetic kidney disease (DKD), blood lipid levels and statin treatment]. RESULTS Our patients were mostly men (58.4%) aged 63±10years, with a duration of diabetes of 13±10years and HbA1c=7.1±0.7%. Of these patients, 84 (25.1%) had DR, which was associated with longer duration of diabetes and greater prevalence of DKD. A total of 605 HbA1c values from previous years were collected for time periods -4±3 months (n=255), -16±4months (n=152), -30±4months (n=93) and -62±26 months (n=105). After adjustment, the association between DR and having an HbA1c higher than the median was significant only for the oldest previous HbA1c values: OR=6.75, 95% CI: 1.90-23.90. Moreover, SAF values were higher in those with DR [2.95±0.67 arbitrary units (AU)] vs 2.65±0.65 AU with no DR (P<0.01) and were also associated with the oldest previous HbA1c values (P<0.01). CONCLUSION Our study found that 25.1% of our well-controlled T2D patients had DR, which was related to both their HbA1c levels from 5years prior to study admission and their SAF values, a marker of glucose memory.

Abstract
AIM While serum fructosamine may be a good marker of glucose control in pregnant women with diabetes, its relationship with macrosomia is still uncertain. METHODS In 130 hyperglycaemic women with singleton pregnancies (117 gestational diabetes mellitus, 13 pregestational diabetes), serum fructosamine and HbA1c levels were measured at 25±7 weeks of gestation. Levels in mothers of infants with and without macrosomic newborns (birth weight>4000g and/or large-for-gestational-age birth weight>90th percentile) were compared using logistic regression analysis adjusted for macrosomia risk factors. RESULTS These 130 pregnant women were 33±5 years old; their BMI before pregnancy was 27.7±6.9kg/m2, and they gained 7.5±5.1kg during the first 6 months of gestation. Glucose control was good according to HbA1c levels (5.3±0.3%; 34±2mmol/mol), yet 17/130 (13%) newborns had macrosomia: 3900±227g vs 3057±512g (P<0.001) in the others. These mothers were older and had higher parity, whereas their BMI scores before pregnancy and gestational weight gains did not differ. Fructosamine levels were also higher at 221±40μmol/L vs 192±22μmol/l (P<0.001), respectively, and remained significant even after adjusting for maternal age, BMI, parity, type of diabetes, antecedents of macrosomia and excessive gestational weight gain. By contrast, HbA1c did not differ between the two groups. In fact, nearly two-thirds (64.7%) of the mothers of macrosomic newborns had fructosamine levels>200μmol/l vs 31.9% of mothers with non-macrosomic newborns (P<0.05). CONCLUSION High fructosamine levels are associated with macrosomia in the newborns of well-controlled hyperglycaemic pregnant women.

Abstract
Abstract
Background: Low uptake and poor adherence to oral drugs for breast cancer prevention and ductal carcinoma in situ has led to an interest in local routes of delivery with the intent of decreasing systemic exposure and reducing toxicity. LTT has emerged as a possible alternative; previous studies have shown selectively higher concentrations in the breast than in the serum with this delivery route. A question related to LTT is whether or not the drug will permeate and distribute throughout the breast, as is expected with oral delivery.
Methods: We conducted a double-blind study of oral versus LTT delivery of the selective progesterone receptor modulator, telapristone acetate (TPA), in a presurgical window setting, enrolling 82 women planning therapeutic or prophylactic mastectomy. We randomized 67 women 1:1, to oral TPA 12 mg daily, or gel TPA applied to both breasts daily (12 mg/breast), for 4 weeks ±1 week. Mastectomy specimens were sampled at 5 non-tumor locations as well as the tumor and lymph node when available. Samples were split in two: drug concentration (conc.) assay using LC-MS/MS and histological evaluation of tissue composition (fat, fibrous stroma, epithelium). The primary endpoint was mean drug conc. across all breast locations (anticipating that the gel would deliver a mean concentration that was >50% of the mean in the oral group). A secondary endpoint was the drug distribution pattern across the breast, expecting that the distribution would be similar. The tumor sample was saved for biomarker assays related to TPA action; these are ongoing, for a pre-planned pooled analysis of data with NCT01800422 (reported in SABCS abstract 851863).
Results: Of 63 evaluable women (33 oral and 30 gel group), 27 had unilateral and 36 had bilateral mastectomy. The mean drug conc. in the oral group was 166.3 ng/G (SE 11.7), and in the gel group was 10.6 ng/G (SE 10.8), (p<.0001). The conc. was variable across the 7 locations tested in both groups. High concentrations were found in the superficial and deep central locations, retroareolar and lateral locations ranked in the middle, and the medial location was discrepant, being high in the oral and low in the gel group. The variation in drug concentration across all locations was not significantly different between groups (Kolmogorov-Smirnov p=0.99). Among women with bilateral mastectomy, drug concentrations were similar between breasts in both oral and gel groups. In the gel group, despite low TPA concentrations, there was evidence of drug metabolism. The major metabolite, CDB 4453 was detectable in 192/193 samples with detectable parent drug. Analysis of drug concentration adjusted for tissue composition is ongoing.
Conclusions: The gel formulation of TPA did not permeate the skin well. However, the drug delivered to the breast was distributed throughout the breast, similar to the oral delivery route, with the highest concentration in the deep central location. These drug distribution data are novel; drug distribution at multiple locations throughout the breast has not previously been shown. Further work is needed to understand breast distribution with formulations known to have good dermal permeation.

Abstract
Background Advanced glycation end-products play a role in diabetic vascular complications. Their optical properties allow to estimate their accumulation in tissues by measuring the skin autofluorescence (SAF). We searched for an association between SAF and major adverse cardiovascular events (MACE) incidence in subjects with Type 1 Diabetes (T1D) during a 7 year follow-up. Methods During year 2009, 232 subjects with T1D were included. SAF measurement, clinical [age, sex, body mass index (BMI), comorbidities] and biological data (HbA1C, blood lipids, renal parameters) were recorded. MACE (myocardial infarction, stroke, lower extremity amputation or a revascularization procedure) were registered at visits in the center or by phone call to general practitioners until 2016. Results The participants were mainly men (59.5%), 51.5 ± 16.7 years old, with BMI 25.0 ± 4.1 kg/m2, diabetes duration 21.5 ± 13.6 years, HbA1C 7.6 ± 1.1%. LDL cholesterol was 1.04 ± 0.29 g/L, estimated Glomerular Filtration Rates (CKD-EPI): 86.3 ± 26.6 ml/min/1.73 m2. Among these subjects, 25.1% were smokers, 45.3% had arterial hypertension, 15.9% had elevated AER (≥ 30 mg/24 h), and 9.9% subjects had a history of previous MACE. From 2009 to 2016, 22 patients had at least one new MACE: 6 myocardial infarctions, 1 lower limb amputation, 15 revascularization procedures. Their SAF was 2.63 ± 0.73 arbitrary units (AU) vs 2.08 ± 0.54 for other patients (p = 0.002). Using Cox-model, after adjustment for age (as the scale time), sex, diabetes duration, BMI, hypertension, smoking status, albumin excretion rates, statin treatment and a previous history of MACE, higher baseline levels of SAF were significantly associated with an increased risk of MACE during follow-up (HR = 4.13 [1.30–13.07]; p = 0.02 for 1 AU of SAF) and Kaplan–Meier curve follow-up showed significantly more frequent MACE in group with SAF upper the median (p = 0.001). Conclusion A high SAF predicts MACE in patients with T1D.

Abstract
Testicular germ cell tumors (TGCT) are a rare neoplasia but are still the most common malignancy in males between the ages of 15 and 44. TGCTs can be divided into two main types: Seminomas (SE) and non-seminomas (NS), the latter with an earlier age of onset and a worst prognosis. One of the most consistent features of TGCTs is the gain of material in the short arm of chromosome 12, that occurs in almost 100% of TGCT cases; 80% of them involve the formation of an isochromosome of the short arm i(12p). This might be the key step that allows the lesion to progress from a germ cell neoplasia in situ (GCNIS), which is a microscopic finding preceding the TGCT and without gain in 12p, to a TGCT. Some tumors, specially SE, present a more restricted amplification of certain 12p regions such as the 12p11.2-12.1 amplicon instead of the i(12p). The mechanism that associates the gain of 12p and the development of invasiveness is not yet well understood but it is believed a number of genes are involved, including DPPA3/STELLA, SOX5, PHC2, ATF7IP and proto-oncogenes Cyclin D2 and KRAS. Genome wide association studies have allowed us to acquire a better knowledge of the pathogenesis of this type of tumor, in which multiple genes show an increase in copy numbers, higher expression or activating mutations in genes related to the KIT/ KITLG pathway like KRAS, BRAF or KIT and KITLG itself. A less frequent subtype of TGCT found in older patients are spermatocytic tumors (ST). It does not develop from a GCNIS and presents a gain of genetic material in chromosome 9 instead of 12. It is believed the overexpression of the gene DMRT1, at 9p24.2, might have a role in the development of ST. In this review we are trying to delineate the most important loci involved in testicular germ tumors, the genes involved in this pathogenesis, and attempting to describe the possible mechanisms behind this tumorigenesis.

Abstract
BACKGROUND The local recurrence of pancreatic cancer is around 30% when complete resection can be achieved. Extended lymphatic resections may improve survival, but increases severe morbidity. As accurate patient selection should be mandatory, a new method is presented for pancreatic sentinel lymph node (SLN) detection with lymphoscintigraphy and gamma probe. MATERIALS AND METHODS Seven patients with cT2N0M0 pancreatic head cancer were enrolled between 2009 and 2012 in this prospective study. One day prior to surgery, preoperative lymphoscintigraphy with echoendoscopic intratumoural administration of Tc(99m)-labelled nanocolloid was performed, with planar and SPECT-CT images obtained 2h later. Gamma probe detection of SLN was also carried out during surgery. RESULTS Radiotracer administration was feasible in all patients. Scintigraphy images showed inter-aortocaval lymph nodes in 2 patients, hepatoduodenal ligament lymph nodes in 1, intravascular injection in 3, intestinal transit in 5, and main pancreatic duct visualisation in 1. Surgical resection could only be achieved in 4 patients owing to locally advanced disease. Intraoperative SLN detection was accomplished in 2 patients, both with negative results. Only in one patient could SLN be confirmed as truly negative by final histopathological analysis. CONCLUSIONS This new method of pancreatic SLN detection is technically feasible, but challenging. Our preliminary results with 7 patients are not sufficient for clinical validation.

Abstract
Malaria is a vectorborne disease caused by protozoan of the genus Plasmodium, which can also be transmitted by the transfusion of infected red blood cells. One year after return from a travel to Honduras, a Spanish traveller developed vivax malaria. Prior to the onset of symptoms, the donor made a donation that tested non-reactive using an immunological test for malaria. Samples from the donor taken before donation and tested by serological and molecular methods were negative but positive at the time of hospital admission. The possible sources of the donors' infection, imported versus locally acquired, are discussed.

Abstract
BACKGROUND Mandatory screening of blood donations for hepatitis B and hepatitis C viruses and human immunodeficiency viruses 1 and 2 requires assays with exceptional sensitivity and specificity. This study reports the results from a direct head-to-head comparison of the Elecsys HBsAG II, Elecsys Anti-HBc, Elecsys Anti-HCV II and Elecsys HIV combi PT immunoassays with the respective ABBOTT PRISM/Architect instrument immunoassays in a multicentre blood bank evaluation study. STUDY DESIGN AND METHODS Assay validation was performed in the blood screening laboratories of four blood bank centres in Austria, Germany, Spain and Thailand, where both first-time donor samples (approximately 6000 donors) and repeat donor samples (approximately 14,000 donors) were screened. RESULTS Of all screened donor samples, 93 (0.46%) were confirmed to be positive using assays from both manufacturers. The specificity of all immunoassays was >99.5% and was comparable between first-time and multiple-time donors. A direct comparison between the assays from Roche and ABBOTT according to Bland and Altman analysis demonstrated equivalent quality. CONCLUSIONS These results suggest that the Elecsys immunoassays for HBV, HCV and HIV infection, with a comparative sensitivity of 100% and a specificity exceeding the common technical specification threshold of >99.5%, meet the stringent performance criteria stipulated for blood donor screening for these infectious agents. Significant differences in the specificity between first-time and repeat donors were not detectable.

Abstract
BACKGROUND AND PURPOSE To delineate the clinical target volume (CTV) in low dose rate (LDR) brachytherapy for prostate cancer, American Brachytherapy Society (ABS) recommends a CTV = prostate. ESTRO advocates a CTV = prostate + 3 mm excluding rectum and many authors use and recommend other different CTVs. This study aims to: (1) evaluate the appropriateness of these recommendations and (2) test the applicability of seed distributions on the different CTVs and contrast the dosimetric differences. MATERIALS AND METHODS Ninety-eight patients treated with (125)I seeds (dose 145 Gy; CTV = prostate) were studied. We established for every patient: (1) risk of extraprostatic extension (EPE), (2) adequacy of original plan to an extended CTV with 3 mm-margin (3) a new planning and seed distribution for this CTV and (4) comparison of dosimetry of both plans. RESULTS Mean risk of EPE was 28.46 %. Original plan, when applied to the extended CTV, resulted in unsatisfactory dosimetry. A plan was generated for the 98 extended CTVs meeting all dosimetric specifications. CONCLUSIONS The risk of EPE is high enough to consider a 3 mm-margin around prostate necessary for all cases. A CTV = prostate + 3 mm except rectum as ESTRO recommends is feasible and would adjust planning to the most probable extension of the tumor.

Abstract
The pontine micturition center or Barrington's nucleus (BN) - besides regulating micturition - co-regulates the activity of other pelvic viscera such as the colon and genitals. At present, this issue is gaining particular importance due to: (i) recent findings of α-synuclein in BN, (ii) known urinary dysfunction in parkinsonian patients (part of the so-called non-motor symptoms), other patients with dementia and as in very old individuals; and (iii) its proximity to the pedunculopontine nucleus, a surgical target in deep brain stimulation for Parkinson's disease (PD). The structural and functional organization of the micturition reflex comprises a coordinating action of somatic motor activity with both divisions of the autonomic nervous system, modulated by trunk encephalic and cortical centers that involve the BN as locus coeruleus and periaqueductal gray matter, among other trunk encephalic structures. The involvement of dopaminergic activity (physiologic inhibition of the micturition reflex mediated by dopaminergic D1 activity) that diminishes in Parkinsonism and leads to overactivity of the micturition reflex is also well known. In this review, the integrating role of the BN in the context of vesical and gastrointestinal behavior is revisited, and the principal morpho-functional findings that associate dysfunction with the urinary disorders that appear during the pre-motor stages of PD are summarized.

Abstract
Abelmoschus esculentus (okra) is one of the polysaccharide rich crop plants. The polysaccharides interfere with nucleic acids and protein isolation thereby affecting the downstream molecular analysis. So, to understand the molecular systematics of okra, high quality DNA, RNA and proteins are essential. In this study we present a method for extracting genomic DNA, RNA and proteins from polysaccharide rich okra tissues. The conventional extraction procedures were integrated with purification treatments with pectinase, RNase and proteinase K, which improved the quality and quantity of DNA as well. Using SDS, additional washes with CIA and NaCl precipitation improved the RNA isolation both quantitatively and qualitatively. Finally, ammonium acetate mediated protein precipitation and re-solubilization increased the quality of total protein extracts from the okra leaves. All of the methods above not only eliminated the impurities but also improved the quality and quantity of nucleic acids and proteins. Further, we subjected these samples to versatile downstream molecular analyses such as restriction endonuclease digestion, RAPD, Southern, reverse transcription-PCR and Western analysis and were proved to be successful.

Abstract
Adaptive Optics corrected flood imaging of the retina has been in use for more than a decade and is now a well-developed technique. Nevertheless, raw AO flood images are usually of poor contrast because of the three-dimensional nature of the imaging, meaning that the image contains information coming from both the in-focus plane and the out-of-focus planes of the object, which also leads to a loss in resolution. Interpretation of such images is therefore difficult without an appropriate post-processing, which typically includes image deconvolution. The deconvolution of retina images is difficult because the point spread function (PSF) is not well known, a problem known as blind deconvolution. We present an image model for dealing with the problem of imaging a 3D object with a 2D conventional imager in which the recorded 2D image is a convolution of an invariant 2D object with a linear combination of 2D PSFs. The blind deconvolution problem boils down to estimating the coefficients of the PSF linear combination. We show that the conventional method of joint estimation fails even for a small number of coefficients. We derive a marginal estimation of the unknown parameters (PSF coefficients, object Power Spectral Density and noise level) followed by a MAP estimation of the object. We show that the marginal estimation has good statistical convergence properties and we present results on simulated and experimental data.

Abstract
BACKGROUND Tigecycline is a new broad spectrum antibiotic that is predominantly used for the treatment of severe infections both in critically ill patients admitted to the ICU and in non-ICU patients with less severe clinical conditions. OBJECTIVE To assess differences in the use of tigecycline between ICU patients and non-ICU patients treated with this antibiotics. MATERIALS AND METHODS Retrospective, cohort, observational study in which cases were defined as patients who received one or more doses of tigecycline over the first 18 months after approval of the drug in a general hospital. Clinical characteristics, indications, route of administration, clinical response, tolerability and outcome were recorded in the groups of ICU and non-ICU patients. Descriptive data and results of the comparison of both cohorts are presented. RESULTS A total of 103 were included in the study, 34(33%) of which received tigecycline during their stay in the ICU. ICU patients compared to non-ICU patients had a higher SAPS II score on admission (39.0 +/- 11.8 vs 26.3 +/- 8.0, p < 0.001) and at the time of starting tigecycline treatment (42.2 +/- 12.6 vs 25.6 +/- 8.2, p < 0.001), were treated with antibiotics for more days (21.4 +/- 30.6 vs 13.6 +/- 30.5 days, p < 0.012) and received a greater number of antibiotic agents concomitantly (85.3% vs 47.8%,p < 0.001), presented a higher selection of emerging bacterial flora (41.2% vs 15.9%, p =0.005), particularly Pseudomonas aeruginosa (20.6%vs 2.9%, p =0.006), higher rate of clinical failure (58.8%vs 21.7%, p < 0.001), longer hospitalization (51.2 +/- 39.4 vs 28.7 +/- 26.3 days, p < 0.001) and higher overall mortality rate (50% vs 14.5%, p < 0.001) and infection-attributed mortality (20.6% vs 7.2%, p =0.047). CONCLUSIONS The patient that receives tigecycline in the ICU has a higher severity level and worse clinical outcome than the non-ICU patient treated with this antibiotic. It is necessary to optimize the indications of tigecycline in the ICU to improve the clinical results.

Abstract
Chondroitin 4-sulfate (C4S) is a bioactive glycosaminoglycan with inductive properties in bone and tissue regeneration. Dicalcium phosphate dehydrate cements (known as brushite) are biocompatible and resorbable materials used in bone and dental surgery. In this study we analyzed the effect of C4S on the setting of a calcium phosphate cement and the properties of the resulting material. Brushite based cement powder was synthesised by mixing monocalcium phosphate with beta-tricalcium phosphate and sodium pyrophosphate. When the concentration of C4S, in the liquid added to the cement powder, was between 1 and 8% the cement final setting time increases. Furthermore, the cement diametral tensile strength remains unaffected when solutions with concentrations of C4S below 5% were used, but decreases at higher C4S concentrations. Calorimetric analysis showed that the cements prepared with C4S alone and in combination with silica gel have a greater content of hydrated water. We concluded from our study that the addition of small amounts of C4S increases the cement setting time without affecting its diametral tensile strength and at the same time improves the cement's hydrophilicity.

Abstract
We present results from a genome-wide scan of a six generation pedigree with 28 affected members with apparently dominant bipolar I disorder from eastern Cuba. Genotypes were obtained using the early access version of the Genechip Mapping 10K Xba array from AFFYMETRIX. Parametric and non-parametric linkage analyses under dominant and recessive models were performed using GENEHUNTER v2.1r5. Two phenotypic models were included in the analyses: bipolar I disorder and recurrent depressive disorder, or bipolar I disorder only. LOD scores were calculated for the entire family combined, and for four subdivisions of the family. For the entire family a suggestive parametric LOD score was obtained under the dominant model and the broader phenotype at 14q11.2-12 (LOD = 2.05). In the same region, a non-parametric LOD score close to genome-wide significance was also obtained, based on the entire family (NPL = 7.31, P-value = 0.07). For two individual branches of the pedigree, genome-wide significance (P < 0.005) was obtained with NPL scores of 8.71 and 12.99, respectively, also in the same region on chromosome 14. Chromosome 5q21.3-22.3 also showed close to genome-wide significant linkage for the complete pedigree (NPL = 7.26, P = 0.07), also supported by significant linkage in one individual branch (NPL = 9.86, P < 0.005). In addition, genome-wide significant nonparametric results (P-values <0.005) were obtained for individual branches at 5p13.1-q12.3, 6p22.3, 8q13.3-21.13, and 10q22.3-23.32. Finally, 2p25.1-25.3, 2p13.3-14, 3p14.2, 6p22.3-24.1, 7p14.1-14.2, 8q12.2-12.3, 10q21.1-21.2, 14q13.1-21.1, 15q15.1-21.2, and 22q12.3-13.32 showed suggestive linkage in the complete family. Most of these potential susceptibility loci overlap with, or are close, to previous linkage findings. The locus on 5q may, however, represent a novel susceptibility locus.

Abstract
Objetivos: Analizamos los resultados clínicos, radiológicos y funcionales mediante un estudio retrospectivo del tratamiento de la artrosis trapeciometacarpiana con técnica de artroplástia de resección-suspensión
Material y Métodos: Hemos revisado una serie de 36 artroplastias de interposición tendinosa utilizando el tendón del flexor carpi radialis intervenidas en nuestro servicio para el tratamiento de la artrosis trapecio-metacarpiana dolorosa e inestable. En 2 pacientes la intervención fue bilateral. Hubo un predominio de mujeres (82%). La media de edad fue de 62 años entre: 50-75. El seguimiento postoperatorio medio fue de 36 meses. Se evaluaron la presencia de dolor, la realización de actividades cotidianas, la movilidad y los resultados radiológicos tanto en el preoperatorio como después de la intervención.
Resultados y Conclusiones: La media de movimiento articular del pulgar aumentó, así como la fuerza de pinza y el ángulo interdigital. El resultado subjetivo fue bueno en el 97% de los casos. Consideramos que esta intervención es una opción valida en el tratamiento de la artrosis trapecio-metacarpiana dolorosa y con pérdida funcional.

Abstract
Four new HLA classical class I alleles in the three loci are described in Caucasian individuals. A*3012 was first suspected by an abnormal serologic pattern that would be explained by the single amino acid substitution at the A30-specific Ser17. B*270505 differs from B*270502 in a silent substitution at an up to now constant position in the B locus. B*3541 encodes for a new Cys at position 118 that has not been encountered in neither human nor primate alleles. Cw*0716 seems to be originated by a large-scale interallelic recombination event between Cw*0701/*0706/*0718 and Cw*020202, giving rise to a new antigen-binding cleft conformation.

Abstract
Homozygosity mapping is a very powerful method for finding rare recessive disease genes in monogenic disorders and may also be useful for locating risk genes in complex disorders, late onset disorders where parents often are not available, and for rare phenotypic subgroups. In the present study, homozygosity mapping was applied to 24 persons with bipolar disorder from 22 inbred families. The families were selected irrespective of whether other affected family members were present or not. A genome wide screen using genotypes from only a single affected person in each family was performed using the AFFYMETRIX GeneChip HuSNP Mapping Assay, which contains 1,494 single nucleotide polymorphisms. At chromosome 17q24-q25 a parametric multipoint LOD score of 1.96 was found at WIAF-2407 and WIAF-2405. When analyzing 19 additional microsatellite markers on chromosome 17q the maximum parametric multipoint LOD score was 2.08, 1.5 cM proximal to D17S668. The present study replicates a recent significant linkage finding.

Abstract
OBJECTIVE Various methods have been used to obtain samples to study the structure of human respiratory muscles and the expression of diverse substances in them. Samples are most often obtained from autopsies, from muscle biopsies during thoracotomy performed because of a localized pulmonary lesion (TLL), and from ambulatory thoracoscopic biopsy in patients free of comorbidity (AT). The disadvantage of the first 2 of these methods lies in the possibility of interference from factors related to the patient's death in the first case or from the disease that necessitated surgery in the second. Although AT is free from the disadvantages of the other 2 methods, it is impossible to obtain samples of the diaphragm the principal respiratory muscle with this procedure. The objective of this study was to analyze the fibrous structure of the external intercostal muscle of patients with chronic obstructive pulmonary disease and to quantify the expression of the principal inflammatory cytokine tumor necrosis factor alpha (TNF-alpha)- and of insulin-like growth factor (IGF-1) in the same muscle, comparing the results obtained with TLL and AT samples. METHODS Prospective and consecutive samples were taken of the external intercostal muscle (fifth space, anterior axillary line) in 15 patients with chronic obstructive pulmonary disease (mean [SD] age 66 [6] years; forced expiratory volume in 1 second 49% [9%] of predicted; PaO2 75 [9] mm Hg). Samples were taken during TLL (8 patients, all with pulmonary neoplasms but carefully selected in order to rule out systemic effects) or TA (7 patients). Patients with serious comorbidity were excluded from the second group. Samples were processed for structural analysis of fibers (immunohistochemical and enzymatic histochemical) and genetic expression of TNF-alpha and IGF-1 (real-time polymerase chain reaction). RESULTS No differences in the structure of fibers were found between the 2 groups. No differences were observed in the expression of TNF-alpha or IGF-1. CONCLUSIONS Using rigorous criteria, the TLL method appears to be suitable for studying the structural characteristics and expression of inflammatory cytokines and growth factors in the external intercostal muscle. Moreover, it can also be inferred that TLL is probably also useful for obtaining samples of the diaphragm, a muscle which cannot currently be sampled by any alternative method.

Abstract
The in vitro activity of gemifloxacin against over 4900 bacterial isolates was determined by microbroth dilution with interpretation in accordance with NCCLS guidelines. Susceptibility results were compared with those for ciprofloxacin, gatifloxacin, levofloxacin and moxifloxacin. Gemifloxacin and the other fluoroquinolones were not affected by either beta-lactamase production or penicillin-resistance in Streptococcus pneumoniae. The MIC90 values for gemifloxacin were: S. pneumoniae 0.063 mg/l; Haemophilus influenzae 0.016 mg/l; Moraxella catarrhalis 0.008 mg/l, methicillin-susceptible Staphylococcus aureus 0.063 mg/l; methicillin-susceptible Streptococcus pyogenes 0.031 mg/l; Enterobacteriaceae 0.031-0.16 mg/l; Pseudomonas aeruginosa 4 mg/l; Neisseria meningitidis 0.008 mg/l. The MIC90 for gemifloxacin was lower than those for the other quinolones tested against S. pneumoniae (ciprofloxacin 2-4 mg/l, gatifloxacin 0.5 mg/l, levofloxacin 1-2 mg/l, moxifloxacin 0.25 mg/l). This study confirms the enhanced potent activity of gemifloxacin against Gram-positive pathogens, its broad-spectrum, Gram-negative activity and indicates that gemifloxacin is likely to have an important role in treating patients with Gram-positive and/or Gram-negative infections.

Abstract
BACKGROUND AND OBJECTIVES A multicentre trial was set up to evaluate the performance of a new leucodepletion protocol. MATERIALS AND METHODS Filtration at high haematocrit was started during collection of red blood cell (RBC) products by apheresis with Trima. SAG-M was added after filtration through the filter. Haematocrits and haemoglobin of the filtered RBCs were measured. Residual leucocytes were determined by Nageotte counting. RESULTS One-hundred and forty seven procedures were carried out. The haematocrit and haemoglobin contents were 57.3 +/- 3.0% and 55.1 +/- 4.3 g/unit, respectively. All products showed low residual leucocyte levels (< or = 0.75 x 106/unit; 99.31% < 1 x 106). CONCLUSION Immediate, on-line, high-haematocrit filtration of red cells collected on Trima resulted in leucoreduced RBCs, which met the AABB and Council of Europe criteria.

Abstract
We have identified a novel polymerase beta (Pol beta)-like enzyme from Leishmania infantum, a parasite protozoon causing disease in humans. This protein, named Li Pol beta, shows a nuclear localization that contrasts with the mitochondrial localization of Pol beta from Crithidia fasciculata, a closely related parasite, the only polymerase beta described so far in Trypanosomatidae. Li Pol beta, that belongs to the DNA polymerase X family, displays an evolutionarily conserved Pol beta-type DNA polymerase core, in which most of the key residues involved in DNA binding, nucleotide binding, dRPase and polymerization catalysis are conserved. In agreement with this, Li Pol beta, overproduced in Escherichia coli, displayed intrinsic DNA polymerase activity. Cell synchronization experiments showed a correlation between both Li Pol beta mRNA and protein levels along the parasite cell cycle. Analysis of these parameters at the different growth phases of the parasite, from the proliferative (non-infective) logarithmic phase to the non-dividing (highly infectious) stationary phase, showed high levels of Li Pol beta at the infective phase of the parasite. The data suggest a role of Li Pol beta in base excision repair in L.infantum, a parasite usually affected by oxygen stress environments into the macrophage host cells.

Abstract
Base excision repair (BER) is a major repair pathway in eukaryotic cells responsible for repair of lesions that give rise to abasic (AP) sites in DNA. Pivotal to this process is the 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity of DNA polymerase beta (Pol beta). DNA polymerase lambda (Pol lambda) is a recently identified eukaryotic DNA polymerase that is homologous to Pol beta. We show here that human Pol lambda exhibits dRP lyase, but not AP lyase, activity in vitro and that this activity is consistent with a beta-elimination mechanism. Accordingly, a single amino acid substitution (K310A) eliminated more than 90% of the wild-type dRP lyase activity, thus suggesting that Lys(310) of Pol lambda is the main nucleophile involved in the reaction. The dRP lyase activity of Pol lambda, in coordination with its polymerization activity, efficiently repaired uracil-containing DNA in an in vitro reconstituted BER reaction. These results suggest that Pol lambda may participate in "single-nucleotide" base excision repair in mammalian cells.

Abstract
Various chemicals, including some bacteria-derived components, modulate natural killer cell (NKC) activity. We have analyzed the effect of wild-type Ty2 and of mutant strain TYT1231 Salmonella typhi-infected monocytes (U937 cells and human autologous monocytes) on NKC cytotoxicity of peripheral blood mononuclear cell (PBMC) and highly purified NKC (HPNKC; CD16+/56+ > 95%; the rest corresponding to CD3+ T-cells). PBMC's co-culture with either S. typhi strain infected U937 cells (medium or non-infected U937 cells as controls) resulted in the induction of lymphocyte activated killer (LAK) cell activity showing cytotoxicity against target human NKC-resistant lymphoblastoid Daudi cell line. Comparable experiments using autologous monocytes gave similar results. Co-culture of HPNKC preparations with either S. typhi strain infected U937 cells resulted in increased LAK cell activity against target Daudi cells in each and everyone of the five samples tested; paired Student's t-test p < 0.01 for both times (20 and 40 h) tested. Similar to the results observed in the experiments using PBMC, we did not find significant differences in the ability between medium and non-infected cells, or between wild-type S. typhi Ty2 and mutant strain TYT1231 infected U937 cells, to induce LAK activity in HPNKC preparations. PBMC co-incubation with either S. typhi strain infected U937 cells or autologous monocytes resulted in significant increases in IL-12, TNF-alpha, and IFN-gamma secretion. In similar experiments using HPNKC samples instead, infected U937 cells significantly increased IL-12 and IFN-gamma, but not TNF-alpha secretion. PBMC co-incubation with non-infected U937 cells, but not with non-infected monocytes, significantly increased supernatant IL-12 and TNF-alpha levels (no significant changes in IFN-gamma were recorded). Secreted cytokines remained essentially unchanged after co-incubating HPNKC preparation with non-infected U-937 cells. Incubation of PBMC or HPNKC preparations with either S. typhi strain infected U937 cells failed to produce significant changes in the expression of NKC lineage (CD16+/56+) or activation (CD28+, CD69+ and CD95+) markers. The ability of infected monocytes to induce LAK activity, release NKC cytokines and upmodulate NKC's CD95+ marker expression was essentially the same for both infecting Salmonella strains used. These results suggest a role for NKC in the physiological defensive response against intracellularly infected monocytes representing, perhaps one of the earliest antimicrobial mechanisms of the innate immune system.
