Abstract
BACKGROUND Persistent complex defects and dysfunctions of the upper aerodigestive tract after tumor surgery represent a major challenge. The aim of this study was to evaluate the effectiveness of an interdisciplinary approach using the free anterolateral thigh flap (ALT) as a reconstruction option in the upper aerodigestive tract. MATERIALS AND METHODS The retrospective study identified 5 patients with complex defects after laryngectomy/pharyngolaryngectomy (LE/PLE) and multiple revision surgeries between 2017 and 2023. The operations were performed by an interdisciplinary team from otolaryngology, plastic surgery, and visceral/thoracic surgery. The results of the microsurgical reconstruction were analyzed. RESULTS There was an average of six previous operations. The defects included tracheoesophageal fistulas, pharyngocutaneous fistulas, neopharyngeal stenosis, and combinations thereof. Successful reconstruction was achieved in 100% of patients using the ALT flap. In 2 patients, ALT flow-through flaps were used with an additional free jejunal interposition (JI) and in 3 patients split-ALT flaps were used. The major complication rate was 40% and the minor complication rate was 20%. CONCLUSION Complex defects of the upper aerodigestive tract with multiple previous operations can be successfully reconstructed. Because of its versatility, the ALT flap seems to be a very good option. Prerequisite for this is an interdisciplinary treatment approach with a critical assessment of patient- and disease-specific factors.

Abstract
We have previously reported that high aldehyde dehydrogenase (ALDH) enzyme activity in breast cancer cells results in breast cancer stem cell (BCSC) properties by upregualting Notch-1 and epithelial mesenchymal markers. This results in chemoresistance in breast cancer. Here, we examined the functional and clinical significance of ALDH expression by measuring the ALDH levels in breast cancer tissues by immunohistochemistry. There was a significantly higher ALDH expression in higher grade breast cancer tumor tissues (Grade- II and III) versus normal breast tissues. Injection of BCSC (ALDH+ and CD44+ /CD22- ) cells resulted in aggressive tumor growth in athymic mice versus ALDH- cells. The ALDH+ and CD44+ /CD22- tumors grow rapidly and are larger than ALDH- tumors which were slow growing and smaller. Molecularly, ALDH+ tumors expressed higher expression of Notch-1 and EMT markers than ALDH- tumors. Oral administration of the naturally occurring Psoralidin (Pso, 25 mg/kg of body weight) significantly inhibited the growth in ALDH+ and ALDH- tumors as well. Psoralidin inhibited Notch-1 mediated EMT activation in ALDH+ and ALDH- tumors-this confirms our in vitro findings. Our results suggest that Notch-1 could be an attractive target and inhibition of Notch-1 by Psoralidin may prevent pathogenesis of breast cancer as well as metastasis. © 2016 Wiley Periodicals, Inc.

Abstract
This study identifies the pattern of twelve Malaysian academic library websites usage among 823 university students. Seventy percent of the respondents knew of the existence of their university library websites. Only 11 percent of respondents searched the Internet before searching printed materials. A majority of the respondents agreed that the Internet adds value to library services and speeds up reference searching. For 23 percent of respondents the Internet was not their first choice in reference searching. A majority of the respondents agreed that the Internet makes reference work more challenging, more fun, more interesting, and more accessible. Eight percent disagreed that using the Internet increases their class assignment grades. 69 percent of respondents did not agree that use of the Internet reduces the students’ need to refer to the library’s helpdesk.

Abstract
Background Nerve transfers are a powerful tool in extremity reconstruction, but the neurophysiological effects have not been adequately investigated. As 81 % of nerve injuries and most nerve transfers occur in the upper extremity with its own neurophysiological properties, the standard rat hindlimb model may not be optimal in this paradigm. Here we present an experimental rat forelimb model to investigate nerve transfers. Methods In ten male Sprague-Dawley rats, the ulnar nerve was transferred to the motor branch of long head of the biceps. Sham surgery was performed in five animals (exposure/closure). After 12 weeks of regeneration, muscle force and Bertelli test were performed and evaluated. Results The nerve transfer successfully reinnervated the long head of the biceps in all animals, as indicated by muscle force and behavioral outcome. No aberrant reinnervation occurred from the original motor source. Muscle force was 2,68 N ± 0.35 for the nerve transfer group and 2,85 N ± 0.39 for the sham group, which was not statically different (p = 0.436). The procedure led to minor functional deficits due to the loss of ulnar nerve function; this, however, could not be quantified with any of the presented measures. Conclusion The above-described rat model demonstrated a constant anatomy, suitable for nerve transfers that are accessible to standard neuromuscular analyses and behavioral testing. This model allows the study of both neurophysiologic properties and cognitive motor function after nerve transfers in the upper extremity.

Abstract
Conjugated linoleic acid (cLA) is a commercially available weight-loss supplement that is not currently regulated by the U.S. FDA. Numerous studies suggest that cLA mediates protection against diseases including cancer, diabetes, atherosclerosis, immune function, and obesity. Based upon these reports, it was hypothesized that supplementation with cLA would improve heart function in aged wild-type (WT) mice. At 10 months of age, mice were treated with cLA, nitrite, or the combination of the two. Echocardiograms revealed that cardiac function was decreased in aged compared to young WT mice, as determined by percentage of fractional shortening. Also, contrary to the hypothesis, mice that received cLA (6-week treatment) had significantly worse cardiac function compared to controls. This effect was attenuated when mice were cotreated with cLA and nitrite. Taken together, these results suggest that cLA-mediated cardiac injury can be circumvented by nitrite supplementation in a murine model of aging.

Abstract
The adoption of Evidence Based Laboratory Medicine (EBLM) has been hampered until today by the lack of effective tools. The SIMeL EBLM e-Thesaurus (on-line Repertoire of the diagnostic effectiveness of the laboratory, radiology and cardiology test) provides a useful support to clinical laboratory professionals and to clinicians for the interpretation of the diagnostic tests. The e-Thesaurus is an application developed using Microsoft Active Server Pages technology and carried out with Web Server Microsoft Internet Information Server and is available at the SIMeL website using a browser running JavaScript scripts (Internet Explorer is recommended). It contains a database (in Italian, English and Spanish) of the sensitivity and specificity (including the 95% confidence interval), the positive and negative likelihood ratios, the Diagnostic Odds Ratio and the Number Needed to Diagnose of more than 2000 diagnostic (most laboratory but also cardiology and radiology) tests. The e-Thesaurus improves the previous SIMeL paper and CD Thesaurus; its main features are a three languages search and a continuous and an easy updating capability.

Abstract
A robust and validated LC-MS-MS quantitative method, using column switching and mutiple reaction monitoring was developed for the analysis of risperidone (RIS) and 9-hydroxyrisperidone in human plasma and saliva. The analytical range was 1-100 ng/ml. The method used 25 microl of sample precipitated with 75 microl of acetonitrile containing internal standard (R068808). Analyses were conducted on a PE Sciex API-III + triple quadrupole mass spectrometer fitted with a Turbo IonSpray source. The method was validated for human plasma using EDTA as the anticoagulant and cross-validated to heparinized human plasma and saliva. The recoveries of risperidone and 9-hydroxyrisperidone were 90-93 and 89-93%, respectively. The validated method was applied to clinical samples to study risperidone and 9-hydroxyrisperidone concentrations in plasma and saliva. Risperidone and 9-hydroxyrisperidone appear in the saliva of patients treated with risperidone. Their detection/quantification in saliva provides evidence for recent adherence with therapy.

Abstract
OBJECTIVE To describe the methodological challenges and decisions made in developing a multisite, controlled study of risperidone in children and adolescents with autism. METHODS Review the design considerations for clinical trials in children with autistic disorder accompanied by severe tantrums, aggressive and/or self-injurious behaviors. These design considerations include the definition of inclusion criteria that are relevant to clinical practice and matching study design to the goal of evaluating short- and long-term effects. Additional ethical and scientific issues concern the length of trial and sample size. RESULTS We undertook a short-term, placebo-controlled study to evaluate the efficacy and safety of risperidone in children and adolescents with autistic disorder. This trial design was followed by an extended open-label maintenance on risperidone to confirm durability of treatment effects and to monitor safety. Finally, a placebo-controlled discontinuation study tested the need for continuous treatment. CONCLUSIONS In the absence of standard pharmacological treatment for children with autistic disorder, a placebo-controlled study remains the most appropriate method of testing efficacy and safety. The clinical relevance of this study is enhanced by the addition of an extended maintenance phase followed by a placebo discontinuation.

Abstract
Several factors appear to impede the development of a valid taxonomy of psychopathology in children and adolescents with mental retardation. These include (a) the lack of a widely accepted definition of psychopathology in mental retardation, (b) disagreement on the nature of the relationship between mental retardation and psychopathology, and (c) insufficient evidence for the reliability and validity of current DSM or ICD systems in this population. In this article, we offer a definition of psychopathology in children with mental retardation; review concepts of the relationship between psychopathology and mental retardation; argue that in moving toward a valid taxonomy factors to be considered should include data from multivariate studies, findings related to behavior phenotypes, and diagnostic considerations with stereotypic behavior and self-injury, organic brain syndromes and pervasive developmental disorders. Finally, we outline a research strategy that may serve as a useful framework for developing a valid taxonomy of psychopathology in this population.

Abstract
BACKGROUND Intracellular glutathione declines progressively in platelet concentrates stored for transfusion, but little is known about the nature of this process. STUDY DESIGN AND METHODS Acivicin, an irreversible inhibitor of gamma-glutamyl transpeptidase, was used to determine the fate of glutathione lost from platelets during storage. Glutathione, cysteinylglycine, cysteine, and their disulfides were measured by high-performance liquid chromatography. RESULTS In control and acivicin-treated platelet concentrates, intracellular glutathione declined progressively during 7 days' storage, with half-disappearance times of 2.12 +/- 0.22 and 2.13 +/- 0.23 days, respectively. No glutathione accumulated accumulated in the medium of control concentrates. In concentrates treated with acivicin, glutathione accumulated in plasma to a level equal to 150 percent of that present in platelets and plasma on Day 1 of storage, which suggested a net synthesis of glutathione during storage. The sum of glutathione, cysteinylglycine, and cysteine in plasma was not different in control and acivicin-treated concentrates; however, plasma from control concentrates contained significantly higher amounts of cysteinylglycine and cysteine. Treatment of concentrates with acivicin had a small favorable effect on plasma lactate dehydrogenase, beta-thromboglobulin, and beta-N-acetylglucosaminidase during storage. CONCLUSION The loss of glutathione from platelets during their storage as concentrates for transfusion is due to its egress into the suspending medium and catabolism by gamma-glutamyl transpeptidase.

Abstract
Triosil 370 has been compared with Urografin 76, and Hypaque 65 by injecting identical volumes into the coronary arteries of human subjects in the course of coronary arteriography. The injection times used were the same and neither the patient nor the coronary artery catheter were moved between injections. The order in which the solutions compared were injected was alternated. The deviation in the ST segment and of the T wave which resulted from the injection was measured. The Triosil caused significantly less change than Urografin and Hypaque. A numerical expression of the T wave deflection derived from the data showed Triosil:Hypaque:Urografin equals I:2.6:2.9.
