Abstract
According to the American Heart Association, approximately 166,200 out-of-hospital cardiac arrests occur each year. It is estimated that a victim's chances of survival are reduced by 7-10 percent for every minute that passes without treatment. Obviously, time is very critical in such situations. In most cardiac arrest cases, there is little to no warning to the victim that their heart has stopped and thus no time to notify others that emergency care is immediately required. To help alert the victim and others that a cardiac arrest episode has occurred, an ambulatory alarm and notification system has been built for individuals at high risk of cardiac arrest. The cardiac arrest alert system uses a ring-style photoplethysmograph that is connected to an armband unit which performs signal processing and wireless transmission and possesses an audible alarm. A wristband interface provides visual and tactile warnings, a reset button and a threshold adjuster. If the user's heart rate goes outside the preset range or is not detected by the system, a visual and tactile warning notifies the user of the situation. If the device is not reset or the problem not rectified within several seconds, the device then goes into full activation mode and sounds a loud alarm to notify nearby individuals who may be able to provide emergency assistance to the user. In full activation mode, the device also wirelessly transmits a signal to a central unit that, when signaled, automatically calls 911 and plays a pre-recorded message that states the incident and specifies the location. An additional phone number can also be stored so that another notification call is automatically performed. The central unit has a speaker so that the notification message is locally audible as well. In emergency situations, the cardiac arrest alert system will provide a life-saving service by rapidly alerting the user as well as nearby individuals and emergency respondents who can provide immediate assistance.

Abstract
Several members of the order Mucorales (subphylum Mucoromycotina) are important agents of severe human infections. The identification of these fungi by using standard mycologic methods is often difficult and time consuming. Frequently, the etiological agent in clinical cases is reported either as a Mucor sp., which is not the most frequent genus of zygomycetes, or only as a member of the Mucorales. For this reason, the actual spectrum of species of zygomycetes and their incidences in the clinical setting is not well known. The goals of this study were to compare the results of the molecular identification of an important set of clinical isolates, received in a mycological reference center from different regions of the United States, with those obtained by using the traditional morphological methods and to determine the spectrum of species involved. We tested 190 isolates morphologically identified as zygomycetes by using sequencing of the internal transcribed spacer (ITS) region of the ribosomal DNA. Molecular identification revealed that Rhizopus oryzae represented approximately half (44.7%) of these isolates. The remainder was identified as Rhizopus microsporus (22.1%), Mucor circinelloides (9.5%), Mycocladus corymbifer (formerly Absidia corymbifera) (5.3%), Rhizomucor pusillus (3.7%), Cunninghamella bertholletiae (3.2%), Mucor indicus (2.6%), Cunninghamella echinulata (1%), and Apophysomyces elegans (0.5%). The most common anatomic sites for clinically significant zygomycetes, as determined by isolates sent to the Fungus Testing Laboratory for identification and/or susceptibility testing and included in this study, were the sinuses, lungs, and various cutaneous locations, at 25.8%, 26.8%, and 28%, respectively. These sites represented approximately 80% of the isolates evaluated. A high level of correlation (92.6%) between morphological and molecular identifications was found.

Abstract
An immunohistochemical study was performed using tissue arrays and specific antibodies against MMPs -1, -2, -7, -9, -11, -13, -14, and TIMPs -1, -2 and -3. More than 5,000 determinations on cancer specimens from 124 patients with invasive breast cancer were performed at the center of the tumor and the invasive front. Immunostaining for MMPs/TIMPs by fibroblasts was evaluated. To identify specific groups of tumors with distinct expression profiles, the data obtained from both fibroblast populations were analyzed by unsupervised hierarchical cluster analysis. Intratumor stromal fibroblasts more frequently showed expression of MMP-2, -7, and -14, and TIMP-3, but less frequently of MMP-9 than fibroblasts at the invasive front. Multivariate analysis showed that a high profile of MMPs and TIMPs staining in both fibroblast populations was the most potent predictor factor of distant metastases, whereas a low staining profile in fibroblasts was associated with a low risk of metastases.

Abstract
PURPOSE To test efficacy and tolerability of non-platinum regimens for advanced non-small-cell lung cancer (NSCLC). METHODS Chemonaive patients with measurable stage IIIB/IV NSCLC treated with gemcitabine and cisplatin (GC), or gemcitabine and docetaxel (GD), maximumsix cycles in a phase IIB trial. RESULTS A total of 108 patients were randomized. Response rates (GC vs. GD, respectively): complete 3.6/2.0%, Partial 30.9/38.0%. Median Overall Survival (OS): 8.9 months in both groups (P = 0.53); and median time to progression (TTP): 6.2/5.5 months respectively (P = 0.61). Toxicities included (GC vs. GD, respectively): grade 3-4 neutropenia 49.1/41.2%; grade 3 thrombocytopenia 30.9/3.9%; grade 3 anemia 14.5/3.9%. Non-haematological toxicity was similar, except for nausea and vomiting, (16.3/2%); renal toxicity (3.7/0%) and hepatic toxicity (5.6/12.7%). CONCLUSIONS With a higher overall response rate and lower toxicity, GD is a good first treatment option for advanced NSCLC.

Abstract
The human umbilical cord is a biological sample that can be easily obtained just after birth. A methodology was developed to perform cultures of human umbilical artery smooth muscle cells (HUASMC) expressing contractile proteins and functional ionic channels. To avoid fibroblast and endothelial cell contamination, we mechanically separated the tunica media, which only contains HUASMC and matrix proteins. To isolate the cells, collagenase V and elastase were used as hydrolyzing enzymes. The isolated cells were plated in collagen-coated dishes to obtain cultures of HUASMC. The cells obtained after different passages (1 to 6) exhibit the characteristic vascular smooth cell morphology and express smooth muscle alpha-2 actin, myosin heavy chain SM1, and alpha subunits of L- and T-type calcium channels (Cav 1.2, Cav 1.2, and Cav 3.2). Electrophysiology recordings for L- and T-type calcium channels were made, indicating that these channels are functional in the cultured cells. In conclusion, the procedure developed allows obtaining cultures of HUASMC expressing contractile proteins and also functional ionic channels. These cells could be used to study cellular and molecular aspects about the regulation of the vascular function.

Abstract
OBJECTIVE The study aimed to establish clinical predictors of non-affective acute remitting psychosis (NARP) and assess whether these patients showed a distinct serotonergic profile. METHOD First-episode never treated psychotic patients diagnosed of paranoid schizophrenia (n=35; 21 men and 14 women) or NARP (n=28; 15 men and 13 women) were included. RESULTS NARP patients showed significantly lower negative symptomatology, better premorbid adjustment, shorter duration of untreated psychosis, more depressive symptomatology and a lower number of 5-HT2A receptors than the paranoid schizophrenia patients. In the logistic regression, the four variables associated with the presence of NARP were: low number of 5-HT2A receptors; good premorbid adjustment; low score in the item 'hallucinatory behaviour' and reduced duration of untreated psychosis. CONCLUSION Our findings support the view that NARP is a highly distinctive condition different from either affective psychosis or other non-affective psychosis such as schizophrenia, and highlight the need for its validation.

Abstract
Aplidin® is an antitumour drug, currently undergoing phase II evaluation in different haematological and solid tumours. In this study, we analysed the antimyeloma effects of Aplidin in the syngeneic 5T33MM model, which is representable for the human disease. In vitro, Aplidin inhibited 5T33MMvv DNA synthesis with an IC50 of 3.87 nM. On cell-cycle progression, the drug induced an arrest in transition from G0/G1 to S phase, while Western blot showed a decreased cyclin D1 and CDK4 expression. Furthermore, Aplidin induced apoptosis by lowering the mitochondrial membrane potential, by inducing cytochrome c release and by activating caspase-9 and caspase-3. For the in vivo experiment, 5T33MM-injected C57Bl/KaLwRij mice were intraperitoneally treated with vehicle or Aplidin (90 μg kg−1 daily). Chronic treatment with Aplidin was well tolerated and reduced serum paraprotein concentration by 42% (P<0.001), while BM invasion with myeloma cells was decreased by 35% (P<0.001). Aplidin also reduced the myeloma-associated angiogenesis to basal values. This antiangiogenic effect was confirmed in vitro and explained by inhibition of endothelial cell proliferation and vessel formation. These data indicate that Aplidin is well tolerated in vivo and its antitumour and antiangiogenic effects support the use of the drug in multiple myeloma.

Abstract
UNLABELLED The aim of the present study was to compare the head position and dental wear of bruxist and non-bruxist children with primary dentition. METHODS All the subjects had complete primary dentition, dental and skeletal class I occlusion and were classified as bruxist or non-bruxist according to their anxiety level, bruxism described by their parents and signs of temporomandibular disorders. The dental wear was drawn in dental casts and processed in digital format. Physiotherapeutic evaluation and a cephalometric radiograph with natural head position were also performed for each child to evaluate the cranio-cervical position for the bruxist group (n = 33) and the control group (n = 20). The variables of the two groups were compared, using the Student t-test and Mann-Whitney U-test. RESULTS A more anterior and downward head tilt was found in the bruxist group, with statistically significant differences compared with the controls. More significant dental wear was observed in the bruxist children. CONCLUSIONS Bruxism seems to be related to altered natural head posture and more intense dental wear. Further studies are necessary to explore bruxism mechanisms.

Abstract
This study was designed to evaluate the efficacy of an inactivated vaccine based on a European-type strain of porcine reproductive and respiratory syndrome virus (PRRSV) against the reproductive form of the syndrome in breeding gilts, and any congenital disease in their piglets. Five gilts were vaccinated twice, following the manufacturer's instructions, before they were inseminated. Nine additional gilts remained unvaccinated and served as positive (five gilts) and negative (four gilts) controls. A European wild-type strain genetically divergent from the vaccine strain was used to challenge the five vaccinated and five unvaccinated positive control gilts at 90 days' gestation. The vaccination of the five seronegative gilts did not produce any clinical signs or adverse reactions. However, the vaccine failed to prevent the clinical signs associated with PRRSV infection, viraemia after the challenge and transplacental infection of their piglets. The reproductive performance of the vaccinated gilts was similar to that of the unvaccinated positive controls, and there were no statistically significant differences in most of the parameters tested. However, the preweaning mortality of the piglets born to the vaccinated gilts was significantly lower than that of the piglets born to the positive control gilts.

Abstract
We constructed noninvasive models to predict significant fibrosis (F > or = 2) and advanced fibrosis (F > or = 3) among human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients, naïve for anti-HCV treatment. A total of 296 patients with liver biopsy were randomly assigned to an estimation group (EG = 226; 70%) and a validation group (VG = 70; 30%). We developed the Hospital Gregorio Marañón (HGM)-1 index, based on platelet count, aspartate aminotransferase (AST) and glucose, to predict F > or = 2 and the HGM-2 index, based on platelet count, international normalized ratio, alkaline phosphatase and AST to predict F > or = 3. The area under the receiver operating characteristic curves (AUROCs) of the HGM-1 index for the EG and the VG were 0.807 and 0.712 respectively. The AUROCs of the HGM-2 index for the EG and the VG were 0.844 and 0.815 respectively. With the HGM-1 index applied to the VG, using best cutoff scores, the negative predictive value (NPV) to exclude F > or = 2 was 54.5% and the positive predictive value (PPV) to confirm F > or = 2 was 93.3%. With the HGM-2 index applied to the VG, using best cutoff scores, the NPV to exclude F > or = 3 was 92.3, and the PPV to confirm F > or = 3 was 64.3%. Thus, HGM-2 accurately predicted F > or = 3 among HIV/HCV-coinfected patients. HGM-1 was less accurate at predicting F > or = 2.

Abstract
INTRODUCTION The serotoninergic system seems to be implicated in characteristic symptoms of borderline personality disorder (BPD) such as affective instability, impulsivity or suicide. Some studies suggest an association between serotonin transporter gene (5-HTT) polymorphisms and some BPD symptoms. Short allele (S) of the 5-HTTLPR polymorphism in the promoter region has been shown to be associated with impulsivity, aggressive behavior, anxiety and neuroticism. Of the variable number of tandem repeat (VNTR) polymorphism in intron 2, BPD patients showed higher frequencies of the allele with the 10 repeats. The aim of this study was to determine the association between 5- HTTLPR and VNTR polymorphism of 5-HTT and personality traits in borderline personality disorder. METHOD A total of 65 BPD patients diagnosed by means of semi-structured interviews SCID-II and DIB-R were included. Two common polymorphisms of 5-HTT were genotyped: the 5-HTTLPR in the promoter region and VNTR in intron 2. Personality traits were assessed by the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). RESULTS Patients with L allele (L/S or L/L) in the 5-HTTLPR polymorphism showed lower scores on the subscale of liking parties and friends. Patients with the allele with 10 repeat of the VNTR polymorphism, showed lower scores in impulsivity, sensation seeking and in the subscale liking of parties and friends. CONCLUSIONS The results suggest a significant association between the 5-HTT gene and some personality traits in BPD. This gene may play a role in the etiology of borderline personality disorder.
