Abstract
This study aims to this study is to compare the co-infection Plasmodium falciparum + Plasmodium vivax and compare the detection of cases of mixed-species malaria using light microscopy versus semi-nested multiplex PCR (sPCR). Investigators collected 3060 samples at a rural health centre in Ethiopia from December 2010 to October 2011. Two capillary blood specimens were taken from each patient, one for diagnosis of Plasmodium infection by light microscopy and the other for sPCR-based diagnosis. LM detected 627 positive cases; these samples, together with 582 negatives by LM, were also subjected to sPCR testing. Of the 627 positive samples by LM, 68.4% were positive for P. vivax, 30.5% for P. falciparum, and 1.1% for P. falciparum + P. vivax co-infection. Using the sPCR technique, we identified 788 samples positive for Plasmodium: 33.0% for P. vivax, 26.5% for P. falciparum, 3.7% for P. falciparum + P. vivax co-infection, 2.0% for P. ovale and 0.8% for P. vivax + P. ovale co-infection. In the case of P. falciparum + P. vivax co-infection, light microscopy diagnosis showed a sensitivity of 11.1%, a specificity of 99.8%, a positive predictive value of 71.4% and a negative predictive value of 96.6%. The concordance rate for identifying P. falciparum + P. vivax co-infection (kappa statistic) with microscopy and sPCR was 0.184. The LM approach has low sensitivity for the detection of mixed-species infections, while sPCR is more useful.

Abstract
BACKGROUND The role of liver biopsy in the evaluation of a candidate for living liver donation is controversial. Some authors suggest doing it routinely, but others do it only in selected cases. The aim of this work was to evaluate the usefulness of protocol liver biopsy in the evaluation of candidates for living liver donation. METHODS Ninety potential candidates for living liver donation were evaluated. In 46 cases donation was contraindicated without the need of liver biopsy. In the remaining 44 candidates, liver biopsy was done on a protocol basis. The usefulness of protocol biopsy was compared with the use of biopsy according to the recommendations of the Vancouver Forum. RESULTS Fifteen of the 44 biopsies were indicated according to the recommendations of the Vancouver Forum. Twelve of them were normal, and 3 had liver steatosis or steatohepatitis. Of the 29 biopsies done per protocol, 28 were normal and 1 showed liver steatosis. Donation was contraindicated according to liver biopsy findings in 3 of the 15 patients with liver biopsy done according to the Vancouver Forum recommendations and in none of the 29 patients with biopsy done per protocol (P = .034). CONCLUSIONS Protocol liver biopsy has a limited utility in the evaluation of the candidates for living liver donation.

Abstract
OBJECTIVE To compare the profile of attributional style of a group of out-patients with bipolar disorder (BD) and schizophrenia (SZ), and a group of healthy controls - along with other social cognition domains - such as emotion recognition and theory of mind (ToM). METHOD A total of 46 out-patients diagnosed with BD, 49 with SZ, and 50 healthy controls were assessed in attributional style (Ambiguous Intentions Hostility Questionnaire), facial emotion recognition (FEIT, FEDT, ER-40), and ToM (Hinting Task). Symptomatology, clinical variables and global functioning were also collected. RESULTS Both groups with SZ and BD showed hostile social cognitive biases, compared with the control group. Patients with BD also showed a capacity for emotional recognition similar to those with SZ and worse than control subjects. In contrast, patients with SZ showed poorer ToM. Subthreshold depressive symptoms and an attributional style toward hostility appeared as the factors with a strongest association to global functioning in BD. In SZ, PANSS score and a tendency to aggressiveness were the most relevant factors. CONCLUSION Attributional style (along with other domains of social cognition) is altered in out-patients with BD and SZ. The presence of residual symptoms and a hostile social cognitive bias may contribute to the functional impairment of both groups.

Abstract
Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. This global burden of cancer continues to increase largely because of the aging and growth of the world population. Although very much progress has been attained in the development of new therapies, there is a clear need of more efficient and selective antitumor drugs for the effective treatment of many types of cancer. Among the different strategies developed to create new antitumor drugs, pleiotropic non-genotoxic effectors have gained interest since this approach is less susceptible to known resistance mechanisms. The cell nucleus is the subcellular compartment where the genetic information and the transcription machinery reside and accordingly where numerous therapeutic agents efficiently work. Hence, nuclear-targeted drugs are expected to kill cancer cells more directly and efficiently. In this review, we discuss the potential of nuclear-targeted drugs as antineoplastic therapeutics and reason the benefits of the strategy to endow ribonucleases with cytotoxic properties based on its targeting into the nucleus.

Abstract
INTRODUCTION Patients with bipolar disorder show social cognition deficits during both symptomatic and euthymic phases of the illness, partially independent of other cognitive dysfunctions and current mood. Previous studies in schizophrenia have revealed that social cognition is a modifiable domain. Social cognition and interaction training (SCIT) is an 18-week, manual-based, group treatment designed to improve social functioning by way of social cognition. METHOD 37 outpatients with DSM-IV-TR bipolar and schizoaffective disorders were randomly assigned to treatment as usual (TAU)+SCIT (n=21) or TAU (n=16). Independent, blind evaluators assessed subjects before and after the intervention on Face Emotion Identification Task (FEIT), Face Emotion Discrimination (FEDT), Emotion Recognition (ER40), Theory of Mind (Hinting Task) and Hostility Bias (AIHQ). RESULTS Analysis of covariance revealed significant group effects for emotion perception, theory of mind, and depressive symptoms. The SCIT group showed a small within-group decrease on the AIHQ Blame subscale, a moderate decrease in AIHQ Hostility Bias, a small increase in scores on the Hinting Task, a moderate increase on the ER40, and large increases on the FEDT and FEIT. There was no evidence of effects on aggressive attributional biases or on global functioning. LIMITATION No follow up assessment was conducted, so it is unknown whether the effects of SCIT persist over time. CONCLUSION This trial provides preliminary evidence that SCIT is feasible and may improve social cognition for bipolar and schizoaffective outpatients.

Abstract
Anastomoses often leak after esophageal surgery; if they are not detected in time, leaks can give rise to complications like fluid collections, superinfections, and mediastinitis. Although these complications usually require surgical treatment, different series of patients successfully treated with conservative or minimally invasive approaches have been reported. We present the case of a patient who developed a mediastinal abscess after epiphrenic diverticulectomy. We treated the abscess with US-guided percutaneous transhepatic drainage to avoid surgical reintervention. Although other cases of a transhepatic approach to thoracic lesions have been reported, to our knowledge this is the first report of this technique in mediastinal abscesses. We recommend that transhepatic drainage be considered a therapeutic option in the management of these complications.

Abstract
Ovine pulmonary adenocarcinoma (OPA) is a contagious tumour caused by infection of sheep with Jaagsiekte sheep retrovirus. Two forms of OPA have been identified, classical and atypical, which can be distinguished clinically and pathologically. Most notably classical OPA is progressive until death, while atypical OPA remains subclinical. In the present study the local immune responses in the lungs of cases of atypical OPA were compared with those from classical cases by immunohistochemistry using a panel of mouse anti-sheep mAbs. Distinct differences in the distribution of immune cell subsets in the two forms of OPA were observed. In particular there was an intratumoural influx of T cell subsets and MHC Class II expression on the tumour cells in atypical OPA, neither of which was seen in classical OPA. It is possible that these differences may contribute, at least in part, to determining the progressive course of classical OPA compared with the subclinical nature of atypical OPA.

Abstract
The wild grapevine, Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi, considered as the ancestor of the cultivated grapevine, is native from Eurasia. In Spain, natural populations of V. vinifera ssp. sylvestris can still be found along river banks. In this work, we have performed a wide search of wild grapevine populations in Spain and characterized the amount and distribution of their genetic diversity using 25 nuclear SSR loci. We have also analysed the possible coexistence in the natural habitat of wild grapevines with naturalized grapevine cultivars and rootstocks. In this way, phenotypic and genetic analyses identified 19% of the collected samples as derived from cultivated genotypes, being either naturalized cultivars or hybrid genotypes derived from spontaneous crosses between wild and cultivated grapevines. The genetic diversity of wild grapevine populations was similar than that observed in the cultivated group. The molecular analysis showed that cultivated germplasm and wild germplasm are genetically divergent with low level of introgression. Using a model-based approach implemented in the software structure, we identified four genetic groups, with two of them fundamentally represented among cultivated genotypes and two among wild accessions. The analyses of genetic relationships between wild and cultivated grapevines could suggest a genetic contribution of wild accessions from Spain to current Western cultivars.

Abstract
Metabolic adaptations are associated with changes in enzyme activities. These adaptations are characterized by patterns of positive and negative changes in metabolic fluxes and concentrations of intermediate metabolites. Knowledge of the mechanism and parameters governing enzyme kinetics is rarely available. However, the signs-increases or decreases-of many of these changes can be predicted using the signs of metabolic control coefficients. These signs require the only knowledge of the structure of the metabolic network and a limited qualitative knowledge of the regulatory dependences, which is widely available for carbon metabolism. Here, as a case study, we identified control coefficients with fixed signs in order to predict the pattern of changes in key enzyme activities which can explain the observed changes in fluxes and concentrations underlying the metabolic adaptations in oncogenic K-ras transformation in NIH-3T3 cells. The fixed signs of control coefficients indicate that metabolic changes following the oncogenic transformation-increased glycolysis and oxidative branch of the pentose-phosphate pathway, and decreased concentration in sugar-phosphates-could be associated with increases in activity for glucose-6-phosphate dehydrogenase, pyruvate kinase and lactate dehydrogenase, and decrease for transketolase. These predictions were validated experimentally by measuring specific activities. We conclude that predictions based on fixed signs of control coefficients are a very robust tool for the identification of changes in enzyme activities that can explain observed metabolic adaptations in carbon metabolism.

Abstract
OBJECTIVE The most common treatment in recurrent malignant ascites is generally temporary peritoneal drainage. We present our experience in placing permanent tunneled catheters in a series of patients and analyze the safety and efficacy of the treatment. MATERIAL AND METHODS We used total aseptic measures in the interventional ultrasonography suite to place permanent tunneled catheters in 10 patients under ultrasonographic guidance and local anesthesia. RESULTS The catheters remained patent for a median of 52 days in the nine patients who died. In one of these, the catheter was withdrawn while still patent due to generalized sepsis. At the end of the study, one patient still had a permeable catheter 124 days after placement. CONCLUSION Although the low number of patients in our series precludes generalizations, tunneled peritoneal catheters seem to be a safe and effective minimally invasive treatment for malignant ascites in terminal oncologic patients. This approach facilitates the draining of the ascites at home, obviating the need for repeated hospital visits and punctures and the risks involved therein. Nevertheless, further experience and prospective randomized trials are necessary.

Abstract
Immunohistochemical staining for cell cycle proteins and heat shock proteins was performed on 17 canine gastric carcinomas. The immunoexpression of p53, p21, p16, Hsp27, and Hsp70 was investigated. A study was conducted to determine the histological type and parameters related to tumor malignancy. Possible associations and trends were assessed between the immunoexpression of each protein and tumor type as well as specific parameters of malignancy. High intratumor frequency of cellular p53 immunostaining was observed (61.96% average), but lower frequencies of p21 and p16 expression were present (34.65% and 10.41%, respectively). The p53 overexpression was associated with tumor infiltration (P = .0258). Expression of p21 was lower in undifferentiated carcinomas, and the loss of expression was associated with histopathological parameters characteristic of a poor prognosis such as lymphatic vessel invasion (P = .0258). The lack of p16 immunoreactivity was related to histopathological characteristics of malignancy such as the presence of evident and multiple nucleoli (P = .0475). In contrast, deep tumor infiltration was observed in those carcinomas with a high p16 index (P = .0475). Hsp70 appeared to be overexpressed in all gastric neoplasms included in this study. This is in contrast to Hsp27, because a group of tumors showed complete lack of Hsp27 immunoexpression, whereas the others displayed extensive Hsp27 immunostaining. The differences in Hsp27 did not correlate with any of the histopathological parameters, but Hsp27 immunoexpression was higher in the undifferentiated carcinoma. No significant differences in the expression of the proteins were found in canine gastric carcinomas according to their histological type. These findings may be useful for establishing a prognosis for canine gastric carcinoma.
