Abstract
Abstract
Background: Breast cancer is the most frequent malignancy in women worldwide. Distinct intrinsic subtypes of breast cancer have different prognoses, and their relative prevalence varies significantly among ethnic groups. Hispanic/Latino (H/L) populations are a genetically admixed and heterogeneous group, with variable levels of European, Native American and African ancestries. Breast cancer in H/L patients is understudied from a molecular standpoint, and most studies reported so far include limited numbers of H/L patients and assign ethnicity based on self-reported data rather than ancestry. This is the first study to explore the prevalence of breast cancer intrinsic subtypes in Colombia and their association with clinicopathological data and genetic ancestry.
Methods: Immunohistochemistry surrogates from the 2013 St. Gallen International Expert Consensus were applied to classify breast cancer into intrinsic subtypes in 301 patients diagnosed between 2008 and 2012 at the Colombian National Cancer Institute. We analyzed the distribution of subtypes by age, histologic type, node status, margins at surgery, AJCC stage, tumor size, Bloom-Richardson grade, histologic features, administration and response to neoadjuvant therapy, adjuvant therapy and recurrence. Genetic ancestry was estimated from a panel of 80 ancestry-informative markers (AIM).
Results: Luminal B breast cancer subtype was the most prevalent in our population (47.5%), followed by luminal A (23.9%), non-basal triple negative (9.3%), basal-like (8.6%), HER2-enriched (8%), and unknown (2.6%). The average of age at diagnosis was 55 and the average tumor size was 4.08 cm. We found statistical significant differences in age at diagnosis, Bloom-Richardson grade, histologic features, adjuvant chemotherapy and recurrence according to intrinsic subtype. Consistent with North American and European observations, basal-like and non-basal triple negative were poorly differentiated tumors and more likely to be diagnosed at younger ages compared to luminal tumors. Patients diagnosed with HER2-enriched, basal and non-basal triple negative breast cancer had the highest African ancestry.
Conclusions: Luminal B tumors, a high risk subset of ER-positive breast cancer, occur with remarkably higher prevalence in Colombian women with breast cancer compared to North American and European populations. Triple-negative subtypes and HER2-enriched tumors appeared to be more frequent among patients with African ancestry, as observed in North American cohorts. Future studies analyzing the molecular profiles of breast cancer in Colombian women will help us understand the molecular basis of this subtype distribution and compare the molecular characteristics of the different intrinsic subtypes in Colombian Hispanic/Latina patients.

Abstract
The French version of vertical-flow constructed wetlands (VFCWs) is characterized by treating directly raw wastewater on a first-stage filter. VFCW is a well developed technology with more than 3,500 plants in operation in France. However, VFCW performance may be affected under the low temperatures reached in mountain areas during winter. The effect of cold conditions over 12 plants, ranging from 75 to 1,900 person equivalent and from 680 to 1,500 m above sea level, was studied over 2 years. The plant hydraulic loads, and air and filter temperatures were continuously measured. In addition, 24-h flow proportional sampling, at each stage of treatment, was conducted in summer (as a reference) and winter. Online measurements of ammonium and nitrates were also analyzed to describe the nitrogen removal dynamics. Since no impact on chemical oxygen demand (COD), biochemical oxygen demand (BOD) and suspended solids removal was observed, the effect of cold temperatures on nitrification was further analyzed. Nitrogen removal was relatively unaffected during winter season. Significant effects were confirmed only for the second stage for loads above 10 gTKN/m²/d (TKN: total Kjeldahl nitrogen). Temperature profiles allowed analysis of the filter buffer capacity in terms of freezing. Under minimal air temperature of -19 °C, no critical operation was observed, although design and operation recommendations can be provided to ensure suitable plant performances.

Abstract
Porophyllum tagetoides is an annual warm-weather herb that has an intense typical smell. Its leaves are commonly used in soup preparation and traditional medicine for treatment of inflammatory diseases. Its volatile compounds and antioxidant properties were evaluated in crude, aqueous and ethanol leaf extract and an oil emulsion using different antioxidant assays in vitro, such as: DPPH radical scavenging activity, redox potential, polyphenol content, reducing power and optical density. A high antioxidative activity was found when comparing leaves with stems. The crude extract from leaves showed a very high reducing power (2.88 ± 0.20 O.D.) and DPPH radical-scavenging activity (54.63 ± 4.80%), in concordance with a major concentration of vitamin C (23.97 ± 0.36 mg/100 g). Instead, the highest polyphenol content (264.54 ± 2.17 mg GAE/g of sample) and redox potential (561.23 ± 0.15 mV) were found by the ethanol and aqueous extract, respectively. Aldehydes and terpenes such as nonanal, decanal, trans-pineno, β-myrcene and D-limonene were the major volatiles found. This study suggests that Porophyllum tagetoides extracts could be used as antioxidants.

Abstract
The purpose of this work was to determine solution- and solid-phase changes associated with the oxidative leaching of arsenopyrite (FeAsS) by Thiobacillus ferrooxidans and a moderately thermoacidophilic mixed culture. Jarosite [KFe(3)(SO(4))(2)(OH)(6)], elemental sulfur (S), and amorphous ferric arsenate were detected by X-ray diffraction as solid-phase products. The oxidation was not a strongly acid-producing reaction and was accompanied by a relatively low redox level. The X-ray diffraction lines of jarosite increased considerably when ferrous sulfate was used as an additional substrate for T. ferroxidans. A moderately thermoacidophilic mixed culture oxidized arsenopyrite faster at 45 degrees C than did T. ferroxidans at 22 degrees C, and the oxidation was accompanied by a nearly stoichiometric release of Fe and As. The redox potential was initially low but subsequently increased during arsenopyrite oxidation by the thermoacidophiles. Jarosite, S, and amorphous ferric arsenate were also formed under these conditions.

Abstract
INTRODUCTION AND AIMS It has been described that patients who receive a transplant display a better Health Related Quality of Life (HRQoL). Our objective was to describe the HRQoL before and after a solid organ transplantation, comparing results among various transplantations. METHODS This HRQoL study using the SF-36 was implemented before as well as at 3 and 12 months posttransplantation. Posttransplantation were compared with pretransplantation scores as well as with the general population. RESULTS One hundred sixty-two renal, 159 liver, and 58 lung candidates were included before transplantation, among whom there were 126 renal, 108 liver, and 22 lung recipients. The median age of all transplant recipients was 53 years with 68% men. The various transplant types began with different HRQoL: lung showed the worst, followed by the liver, and then renal. The scores of the SF-36 before and 3 months posttransplantation showed significant improvements, except for "Pair." At 12 versus 3 months, mental health was somewhat better for renal, and almost all dimensions showed significant improvement for liver and lung patients. All subjects showed clear improvements after transplantation. CONCLUSION All patients showed clear improvements after transplantation when mental health was compared with the general population, particularly lung transplant recipients who expressed the greatest improvement. However, they still showed deficits in physical health.

Abstract
1551 Background: Community involvement is critical to advance cancer education and prevention in minority communities. Researchers must be knowledgeable of the target community's basic cultural beliefs and linguistic needs. This study sought to identify the best approach for conducting community based cancer research in South Texas Hispanic communities. We report our experiences and lessons learned with participants and site recruitment and retention. Methods: We introduced a community based, culturally relevant breast and cervical cancer screening and early detection program, Esperanza y Vida, to address barriers and disparities in four border communities (urban, rural, colonia, and small border town). These areas represent the diverse South Texas Mexican American population in terms of language use, immigration status, and length of time in the US. Within these communities we recruited a grassroots community organization, faith-based health center, rural hospital district, and federally qualified health center. Results: Focus groups were conducted with women and men to assess knowledge, attitudes, and beliefs about women's cancers. To successfully recruit participants, we implemented various techniques to engage the community and establish sustainable relationships. These included community health worker recruitment of community members, traditional recruitment (flyers, posters, word of mouth), key community and cultural leader support, and discussions with local groups and health organizations. We and our community partners identified and overcame investigator/community barriers (lack of community knowledge, community integration into the research process, community understanding of research methods, reluctance to develop innovative approaches). Consequently, participants are eager to remain with the program and are individually and collectively mobilizing others to create a sustainable and durable program. Conclusions: 1. Cultural leader engagement worked best for participant recruitment in the small border town and colonia settings, while key community leader engagement was most effective in the small city urban and rural settings. 2. Research/community partners must identify and discuss project barriers regardless of the fear of creating discordance to reach solutions. No significant financial relationships to disclose.

Abstract
Measurements of iron-plasma transmission at 156+/-6 eV electron temperature and 6.9+/-1.7 x 10(21) cm(-3) electron density are reported over the 800-1800 eV photon energy range. The temperature is more than twice that in prior experiments, permitting the first direct experimental tests of absorption features critical for understanding solar interior radiation transport. Detailed line-by-line opacity models are in excellent agreement with the data.

Abstract
Management of airway infections caused by Pseudomonas aeruginosa is a serious clinical challenge, but little is known about the microbial ecology of airway infections in intubated patients. We analyzed bacterial diversity in endotracheal aspirates obtained from intubated patients colonized by P. aeruginosa by using 16S rRNA clone libraries and microarrays (PhyloChip) to determine changes in bacterial community compositions during antibiotic treatment. Bacterial 16S rRNA genes were absent from aspirates obtained from patients briefly intubated for elective surgery but were detected by PCR in samples from all patients intubated for longer periods. Sequencing of 16S rRNA clone libraries demonstrated the presence of many orally, nasally, and gastrointestinally associated bacteria, including known pathogens, in the lungs of patients colonized with P. aeruginosa. PhyloChip analysis detected the same organisms and many additional bacterial groups present at low abundance that were not detected in clone libraries. For each patient, both culture-independent methods showed that bacterial diversity decreased following the administration of antibiotics, and communities became dominated by a pulmonary pathogen. P. aeruginosa became the dominant species in six of seven patients studied, despite treatment of five of these six with antibiotics to which it was sensitive in vitro. Our data demonstrate that the loss of bacterial diversity under antibiotic selection is highly associated with the development of pneumonia in ventilated patients colonized with P. aeruginosa. Interestingly, PhyloChip analysis demonstrated reciprocal changes in abundance between P. aeruginosa and the class Bacilli, suggesting that these groups may compete for a similar ecological niche and suggesting possible mechanisms through which the loss of microbial diversity may directly contribute to pathogen selection and persistence.

Abstract
AIMS To assess cytokeratin (CK) and thyroid transcription factor (TTF)-1 expression in primary epithelial lung tumours by comparison with non-pulmonary carcinomas and to correlate it with their histological type and grade. METHODS AND RESULTS Immunohistochemistry using antibodies against CKs 5/6, 7, 19, 20 and TTF-1 was applied to 165 primary and 37 secondary epithelial lung tumours. CK5/6 is a sensitive and specific marker of lung squamous carcinomas being positive in 100% of cases. CK7 is a common marker of primary lung adenocarcinomas (100% of cases) but with a lower specificity since it is also observed in other primary lung carcinomas (70% of large-cell neuroendocrine carcinomas, 40% of large-cell carcinomas, 23% of squamous carcinomas) but also in 27% of non-pulmonary adenocarcinomas. Addition of an anti-CK20 may be useful to prove or disprove the pulmonary origin of an adenocarcinoma when there is a history of colon cancer. CK19 is ubiquitous but a predominant or exclusive 'dot-like' pattern is very suggestive of high-grade neuroendocrine carcinoma. TTF-1 is a very sensitive and specific marker to document the pulmonary origin of an adenocarcinoma if a thyroid origin is excluded. Its expression in neuroendocrine lung tumours depends on the tumour grade. CONCLUSIONS Immunohistochemical expression of CKs and TTF-1 may be correlated with histological type and grade of lung primary epithelial tumours and may allow them to be distinguished from non-pulmonary carcinomas.

Abstract
The microbiological leaching of chalcopyrite (CuFeS(2)) is of great interest because of its potential application to many CuFeS(2)-rich ore materials. However, the efficiency of the microbiological process is very limited because this mineral is one of the most refractory to bacterial attack. Knowledge of bacterial role during chalcopyrite oxidation is very important in order to improve the efficiency of bioleaching operation. The oxidative dissolution of a massive chalcopyrite electrode by Acidithiobacillus ferrooxidans was evaluated by electrochemical impedance spectroscopy (EIS) and atomic force microscopy (AFM). A massive chalcopyrite electrode was utilized in a Tait-type electrochemical cell in acid medium for different immersion times in the presence or absence of bacterium. The differences observed in the impedance diagrams were correlated with the adhesion process of bacteria on the mineral surface.

Abstract
The effects of metal bioleaching on nutrient solubilization, especially nitrogen and phosphorous, from anaerobically-digested sewage sludge were investigated in this work. The assessment of the sanitary quality of the anaerobic sludge after bioleaching was also carried out by enumerating indicator (total coliforms, fecal coliforms, and fecal streptococci) and total heterotrophic bacteria. The experiments of bioleaching were performed using indigenous sulphur-oxidizing bacteria (Thiobacillus spp.) as inoculum and samples of anaerobically-digested sludge. Nitrogen and phosphorous solubilization from sewage sludge was assessed by measuring, respectively, the concentration of Total Kjeldahl Nitrogen, ammonia, nitrate/nitrite, and soluble and total phosphorous before and after the bioleaching assays. At the end of the experiment, after 4 days of incubation (final pH of 1.4), the following metal solubilization yields were obtained: zinc, 91%; nickel, 87%; copper, 79%; lead, 52%; and chromium, 42%. As a result of sludge acidification, the viable counts of selected indicator bacteria were decreased to below the detection limit (4 x 10(3) cfu 100 ml(-1)), followed by an increase in the mineral fraction of nitrogen (from 6 to 10%) and in the soluble fraction of phosphorous (from 15 to 30%). Although some loss of sludge nutrients can occur during solid-liquid separation following bioleaching, its beneficial effects as metal removal and reduction of pathogenic bacteria are sufficient to consider the potential of this treatment before sludge disposal onto agricultural fields.

Abstract
Nineteen strains of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, including 12 strains isolated from coal, copper, gold and uranium mines in Brazil, strains isolated from similar sources in other countries and the type strains of the two species were characterized together with the type strain of A. caldus by using a combination of molecular systematic methods, namely ribotyping, BOX- and ERIC-PCR and DNA-DNA hybridization assays. Data derived from the molecular fingerprinting analyses showed that the tested strains encompassed a high degree of genetic variability. Two of the Brazilian A. ferrooxidans organisms (strains SSP and PCE) isolated from acid coal mine waste and uranium mine effluent, respectively, and A. thiooxidans strain DAMS, isolated from uranium mine effluent, were the most genetically divergent organisms. The DNA-DNA hybridization data did not support the allocation of Acidithiobacillus strain SSP to the A. ferrooxidans genomic species, as it shared only just over 40% DNA relatedness with the type strain of the species. Acidithiobacillus strain SSP was not clearly related to A. ferrooxidans in the 16S rDNA tree.

Here, we set network 1.2 in the Y-chromosomal phylogenetic tree, date it with respect to other lineages associated with the same movements by other authors, examine its diversity by means of tri- and tetranucleotide loci and discuss the implications in reconstructing the spread of this group of chromosomes in the Mediterranean area. Our results define a tripartite phylogeny within HG 9 (Rosser et al. 2000), with the deepest branching defined by alleles T (Haplogroup Eu10) or G (Haplogroup Eu9) at M172 (Semino et al. 2000), and a subsequent branching within Eu9 defined by network 1.2. Population distributions of HG 9 and network 1.2 show that their occurrence in the surveyed area is not due to the spread of people from a single parental population but, rather, to a process punctuated by at least two phases. Our data identify the wide area of the Balkans, Aegean and Anatolia as the possible homeland harbouring the largest variation within network 1.2. The use of recently proposed tests based on the stepwise mutation model suggests that its spread was associated to a population expansion, with a high rate of male gene flow in the Turkish-Greek area.

Abstract
The levels of haplotype diversity associated with different alpha1-antitrypsin (PI) alleles were assessed by the analysis of three microsatellites located within or close to corticosteroid-binding globulin (CBG), alpha1-antitrypsin [PI-(TG)n] and protein C inhibitor [PCI-(TG)n] loci in three populations with different historic backgrounds: Portugal, the Basque Country and São Tomé Príncipe (Gulf of Guinea). Unlike the more distant PCI-(TG)n repeat, allelic variation at PI-(TG)n reflected distinct phases of mutational recovery of microsatellite diversity around different founder alleles and showed a considerable differentiation between alpha1-antitrypsin protein variants. In accordance with population history, the Basque sample presented overall reduced levels of microsatellite variation. The African sample, although presenting the highest PCI-(TG)n diversity, showed a lineage-specific reduction in PI-(TG)n heterozygosity within the oldest M1Ala213 variant that could have been caused by (1) selection at a closely linked locus or (2) biases in the microsatellite mutation process leading to a stable equilibrium distribution. Age estimates of alpha1-antitrypsin variants based on microsatellite variation suggest that the Z deficiency allele appeared 107-135 generations ago and could have been spread in Neolithic times. The S mutation has an older 279- to 470-generation age, indicating that its high frequencies in Iberia did not result from a recent bottleneck and that PI*S could have originated in this region. M2 and M3 types had lower age estimates than would be expected from their wide geographical distributions, suggesting that their dispersion in Europe might have been preceded by important bottlenecks.

Abstract
This study investigated the association between biomarkers of fetal exposure to cigarette smoke at the end of pregnancy, cotinine in cord serum and in maternal and newborn urine samples, and quantitative measurement of smoking intake and exposure evaluated by maternal self-reported questionnaire. Study subjects were 429 mothers and their newborns from a hospital in Barcelona, Spain. A questionnaire including smoking habits was completed in the third trimester of pregnancy and on the day of delivery. Cotinine concentration in cord serum was associated with daily exposure to nicotine in nonsmokers and with daily nicotine intake in smokers. The geometric mean of cotinine concentration in cord serum statistically discriminated between newborns from nonexposed and exposed nonsmoking mothers, and between these two classes and smokers, and furthermore was able to differentiate levels of exposure to tobacco smoke and levels of intake stratified in tertiles. Urinary cotinine levels in newborns from nonsmoking mothers exposed to more than 4 mg nicotine daily were statistically different from levels in two other categories of exposure. Cotinine concentration in urine from newborns and from mothers did not differentiate between exposure and nonexposure to environmental tobacco smoke (ETS) in nonsmoking mothers. Cord serum cotinine appeared to be the most adequate biomarker of fetal exposure to smoking at the end of pregnancy, distinguishing not only active smoking from passive smoking, but also exposure to ETS from nonexposure.

Abstract
Poly(2-hydroxyethyl methacrylate-co-acrylamide) hydrogels crosslinked with ethylen glycol dimethacrylate were used as devices for the in-vivo drug release of 5-fluorouracil (5-FU). Drug-loaded hydrogels were subcutaneously implanted in the back of Wistar rats. All hydrogel discs reached an equilibrium swelling degree, which was slightly larger than that determined in-vitro. After 30 days of implantation, the hydrogel discs were transparent, and without fracture or apparent degradation. In addition, a fibrous capsule was not detected around the hydrogels that had greater hydration degrees. Release of 5-FU from these hydrogels allows the drug to remain in the plasma from 1 to 5 days, in spite of its short plasma half-life (15 min). This was an improvement of up to 98-times compared with the intraperitoneal drug administration. Administration of 5-FU by implantation of 2-hydroxyethylmethacrylate-co-acrylamide copolymeric hydrogels seems to be a good candidate for 5-FU therapy, since the drug released results in a therapeutically suitable plasma concentration of 5-FU for an extended period of time, despite the short half-life of the drug.

Abstract
Blood samples from 489 unrelated Caucasian Mestizo and 252 individuals of African descent in Colombia were amplified and typed for three short tandem repeat (STR) markers (D12S1090, D3S1744, and D18S849). All markers conformed to Hardy-Weinberg equilibrium expectations in both populations studied. In addition, heterozygosity, mean exclusion chance, polymorphism information content, discrimination power, and the assumption of independence within and between loci were determined. The mean exclusion chance for all three STR markers is 0.9750 in the Caucasian Mestizo population and 0.9731 in the African Colombian Population. The discrimination power is 0.999925 and 0.999911 in the Caucasian Mestizo and African Colombian respectively.

Abstract
Respirometric experiments demonstrated that the oxygen uptake by Thiobacillus ferrooxidans strain LR was not inhibited in the presence of 200 mM copper. Copper-treated and untreated cells from this T. ferrooxidans strain were used in growth experiments in the presence of cadmium, copper, nickel and zinc. Growth in the presence of copper was improved by the copper-treated cells. However, no growth was observed for these cells, within 190 h of culture, when cadmium, nickel and zinc were added to the media. Changes in the total protein synthesis pattern were detected by two-dimensional polyacrylamide gel electrophoresis for T. ferrooxidans LR cells grown in the presence of different heavy metals. Specific proteins were induced by copper (16, 28 and 42 kDa) and cadmium (66 kDa), whereas proteins that had their synthesis repressed were observed for all the heavy metals tested. Protein induction was also observed in the cytosolic and membrane fractions from T. ferrooxidans LR cells grown in the presence of copper. The level of protein phosphorylation was increased in the presence of this metal.

Abstract
PURPOSE It is well known that altitude natives differ from sea level natives in aspects of fluid and electrolyte homeostasis. METHODS To evaluate exercise and environmental influences on the electrolyte and water status in hypoxia adapted subjects, we investigated 11 well-trained marathon runners (33.7 +/- 0.7 yr, 60.5 +/- 1.9 kg), native to an altitude above 2600 m, before and after two marathon races. One competition was held at moderate altitude (AM, 2650 m, 14 degrees C, 55% RH, running time 3 h 6 min +/- 22 min) and another under tropical conditions (HM, 470 m, 28 degrees C, 70% RH, running time 2 h 54 min +/- 30 min). Blood samples were taken 3 d before, immediately after, 1 h after, and 24 h after the races. RESULTS The loss in body fluid was calculated to be 2.15 L during AM and 5.05 L during HM, respectively. It was compensated mostly by ingested fluids without electrolyte content and by metabolically produced water, which led to hyponatremia during AM (plasma [Na+] from 144.3 +/- 0.7 to 131.7 +/- 2.1 mmol x L(-1)). Severe dehydration without significant changes in plasma [Na+] could be detected after HM. Serum antidiuretic hormone concentrations and serum aldosterone concentrations significantly increased during both races and remained at a high level for at least 1h after both competitions. Serum atrial natriuretic peptide (ANP) concentrations were at a high level at rest, increasing during HM, and decreasing during AM. CONCLUSION Under tropical conditions, we found a severe state of dehydration characterized by an extended ANP-response, which was not prevented by water intake during the race. Under hypoxic conditions, however, we found that hyponatremia had developed. This can be partly explained by pure water intake and metabolically produced water, and also, possibly, by a special hypoxia-induced effect.

Abstract
Although the predictive factors of postoperative mortality after coronary artery surgery are well known, those predictive of long-term survival have received less attention. This study reviews the outcome of a group of 480 patients between 50 and 65 years of age, operated between 1984 and 1986. The patients were classified in two groups according to the presence or absence of internal mammary artery bypass grafts: Group I (304 patients with saphenous vein bypass grafts alone) and group II (176 patients with an internal mammary artery +/- saphenous vein bypass grafts). The long-term results were assessed according to 3 criteria: isolated cardiac mortality: cardiac mortality associated with a repeat revascularisation procedure and cardiac mortality associated with reoperation or recurrence of angina. Cardiac survival at 10 years was significantly better after internal mammary-LAD bypass: 91.4% (CI 87.1-95.1) than after saphenous vein bypass grafting alone: 79.6% (CI 74.8-84.4) (p = 0.012). Univariate analysis identified the following poor predictive factors: three vessel disease (p = 0.03), preoperative left ventricular dysfunction with an ejection fraction inferior to 45% (p = 0.0001), incomplete revascularisation (p = 0.0003), use of venous bypass graft alone (p < 0.014) and perioperative infarction (p = 0.0254). For each criterion of survival (cardiac isolated or associated with a new revascularisation and/or recurrence of angina), multivariate analysis identified three independent predictive factors of long-term extramortality: not using internal mammary artery-LAD bypass graft, incomplete revascularisation and preoperative hypertension. This study confirms the beneficial effects of internal mammary-LAD artery grafting on long-term survival after coronary artery surgery, and also demonstrates the prejudicial effects of hypertension.

Abstract
Traditionally, most of transverse rectus abdominis musculocutaneous (TRAM) flap shaping takes place after transfer of the flap to the chest. As skin-sparing mastectomies become more commonplace, flap tailoring becomes a more difficult and lengthy process due to lack of exposure through these small incisions. Immediate breast reconstruction was performed on 40 patients using the mastectomy specimen as a model for TRAM flap fabrication. Detailed measurements of the specimen were taken and a template was created as a guide for shaping the flap. All flaps were shaped on the abdomen, and additional tailoring was not necessary after transfer to the chest. Significant differences in weight were recorded between the shaped flap and the specimen. Size, shape, and orientation were found to be more reliable parameters in matching the flap to the specimen than approximating their weights. This approach allows for greater accuracy in shaping the flap, reduces operative time, and avoids flap manipulation after transfer.

Abstract
Blood samples from 202-208 unrelated Basque Country autochthonous individuals were amplified, typed and their allele frequencies were determined. Results demonstrate the assumption of independence within and between the loci analyzed. Therefore, a Basque population database can be used in identity testing to estimate the frequency of a multiple PCR-based locus DNA profile.
