Abstract
Abstract
Background
The implications of sharing one's health data are far-reaching. Potential applications of health data range from the delivery of treatments tailored to individuals' characteristics to improvements in public health, while also posing concerns about privacy, social justice and equity. Making informed decisions about health data sharing thus requires thorough consideration of the scientific, ethical and personal implications of donations. This study assessed participants' preferences regarding decision-making about health data sharing for research, including the need for support by data counsellors.
Methods
This observational cross-sectional study includes 159 patients and 479 carers followed at two reference centres for rare diseases in a Portuguese academic hospital, between June 2019 and March 2020. Participants were asked about preferred modes of decision-making: deciding on their own, deciding with support from another person, or delegating the decision to someone else. Those who responded the last two options also reported who they would choose for support or delegation: family or friends; a data counsellor; a professional with no specific training on data counselling; other. Data were analysed using descriptive and inferential statistics.
Results
The majority of respondents would prefer to decide with support (62%), 37% would prefer to decide on their own and 1% would opt to delegate the decision of sharing health data. Among those who expressed a preference for support, 60% would like to rely on a data counsellor. Carers, older and higher educated participants, and those with upper white-collar occupations and who were satisfied with their own health were significantly more likely to select data counsellors as their preferred source of support when engaging in decision-making about health data sharing for research (p < 0.05).
Conclusions
This study supports recommendations for the creation of a new professional specialty of health data counsellors.
Key messages
Most participants express the need for support in making decisions about health data sharing for research, with 60% preferring support from a data counsellor. As a new professional specialism, health data counselling can help to advance informed public participation in health research.

Abstract
During the last decade, several studies have shown that mitochondrial parameters, such as integrity, respiratory activity, membrane potential and ROS production are intimately linked with sperm quality. Given the limitations of conventional semen analyses in terms of predicting male fertility, an increasing number of studies are focusing on the characterization of sperm mitochondria in order to more accurately assess sperm functionality. Moreover, mitochondria from several organs, such as the liver, have been described as a powerful screening tool for drug safety, being an easy in vitro model to assess the toxicity of distinct families of compounds. Given that mitochondrial functionality is intimately related to sperm homeostasis, it has become important to understand how compounds, ranging from dietary supplements, environmental pollutants, dependency-inducing drugs to pharmacological agents (such as erectile dysfunction-targeted drugs and male contraceptives) affect sperm mitochondrial function. In this review, we discuss studies describing the effects of various chemical agents on spermatozoa, with particular emphasis on mitochondrial function. From the extensive literature analyzed, we conclude that in some cases the role of sperm mitochondria as putative predictors of sperm functionality is very obvious, while in others further studies are needed to clarify this issue.

Abstract
Congenital pulmonary lymphangiectasia (CPL) and chylothorax (CC) are rare lymphatic developmental disorders. We report six clinical cases of CPL and CC that were admitted to our level III neonatal intensive care unit over the last 20 years. One case of unilateral CC was successfully treated with pleuro-amniotic shunt; three cases of bilateral CC were associated to lung hypoplasia, hydrops fetalis, and generalized lymphangiectasias; one case of CPL was associated with obstructive congenital heart defect; one case of unilateral CC was successfully treated with thoracocentesis and medium-chain triglyceride diet. Mortality was high (66.6%).

Abstract
Computed tomography (CT) is one of the most used techniques in medical diagnosis, and its use has become one of the main sources of exposure of the population to ionising radiation. This work concentrates on the paediatric patients, since children exhibit higher radiosensitivity than adults. Nowadays, patient doses are estimated through two standard CT dose index (CTDI) phantoms as a reference to calculate CTDI volume (CTDI vol) values. This study aims at improving the knowledge about the radiation exposure to children and to better assess the accuracy of the CTDI vol method. The effectiveness of the CTDI vol method for patient dose estimation was then investigated through a sensitive study, taking into account the doses obtained by three methods: CTDI vol measured, CTDI vol values simulated with Monte Carlo (MC) code MCNPX and the recent proposed method Size-Specific Dose Estimate (SSDE). In order to assess organ doses, MC simulations were executed with paediatric voxel phantoms.

Abstract
The perspective of adding digital breast tomosynthesis (DBT) to standard mammography in screening raises concerns regarding the dose absorbed by the fibroglandular breast tissue. Thus, it is important to estimate accurately the mean glandular dose (MGD), although there are no standard protocols for dosimetry, concerning DBT. This study aims at introducing backscatter factors (BSF) to calculate the entrance surface air kerma (ESAK), directly on patients or phantoms, in order to be introduced in the formalism proposed by Dance et al. MCNPX simulations were performed, to mimic a DBT acquisition, for a wide range of X-ray spectra. A homogeneous breast phantom with 50 % of glandular tissue was considered and several thicknesses were evaluated. Dose measurements were performed, to validate and support the simulation results. The BSF may indicate a real MGD estimation in vivo for DBT examinations and contribute for the improvement of the current guidelines used in these applications.

Abstract
Interventional cardiology (IC) procedures can be complex, requiring the operators to work near the patient, during long exposure times. Owing to scattered radiation in the patient and the fluoroscopic equipment, the medical staff are exposed to a non-uniform radiation field and can receive high radiation doses. In this study, it is proposed to analyse staff doses obtained in real time, during IC procedures. A system for occupational dosimetry in real time was used. In order to identify some parameters that may affect the staff doses, Monte Carlo (MC) calculations, using MCNPX v.2.7.0 code and voxel phantoms, were performed. The data obtained from measurements, together with MC simulations, allowed the identification of actions and behaviours of the medical staff that could be considered a risk under routine working conditions. The implementation of this monitoring system for exposure of personnel may have a positive effect on optimisation of radiological protection in fluoroscopically guided cardiac procedures.

Abstract
The search for cheap, easy-to-use and effective spermicides and microbicides to help avoid unwanted pregnancies and the transmission of sexually transmitted diseases has been ongoing for many years. This review takes into account compounds designed to act both as microbicides and spermicides for multipurpose prevention, and focuses on the required methodological studies to evaluate their safety, especially cytotoxicity. A comprehensive literature review was conducted on the synthesis, development, advantages and disadvantages of vaginal multi-function compounds. The available data shows that after several setbacks, there is a current interest in the synthesis and in the activity of novel dual-function substances. The study of well-known compounds with distinctive mechanisms of action provides a solid starting point to explore the possible development of such strategies. However, a completely safe and efficient compound for commercialization has yet to be identified.

Abstract
AIM Over the last two decades, new therapies have emerged for the management of congenital diaphragmatic hernia (CDH). The aim of this paper was to review our experience in the management of newborns diagnosed with CDH over a 14-year period. METHODS Review of maternal and infant medical records, 1997-2010. RESULTS Eighty newborns with CDH; 21 (26%) were preterm and 28 (35%) of low birthweight (<2500 g), including 3 (4%) of very low birthweight (< 1500 g). Prenatal diagnosis was made in 53 (66%) cases. The location of the hernia was: left side 48 (90.5%); right 4 (7.5%); bilateral 1 (1%). Corrective surgery was performed in 58 (73%) patients. High frequency oscillatory ventilation was used in 10 (12.5%), inhaled nitric oxide in 18 (22.5%), sildenafil in 15 (18.7%) and extracorporeal membrane oxygenation in 1 (1%). The overall survival was 49% (N.=39). Since 2003, the overall survival raised to 64%. The survival rate of the appropriate for gestational age term newborns without other congenital/chromosomal anomaly or hydrops fetalis was 67% (24/36). CONCLUSION Our survival rate for congenital diaphragmatic hernia has improved over the last 14 years, associated to the use of new therapies, such as high-frequency oscillation ventilation (HFOV), inhaled nitric oxide and sildenafil.

Abstract
The MSH2 c.388_389del mutation has occasionally been described in Lynch families worldwide. At the Portuguese Oncology Institute in Porto, Portugal, we have identified 16 seemingly unrelated families with this germline mutation. To evaluate if this alteration is a founder or a recurrent mutation we performed haplotype analysis in the 16 Portuguese index cases and 55 relatives, as well as in four index cases and 13 relatives reported from Germany, Scotland, England, and Argentina. In the Portuguese families we observed a shared haplotype of approximately 10 Mb and all were originated from the north of Portugal. These results suggest that this alteration is a founder mutation in Portugal with a relatively recent origin. In the reported families outside Portugal with this mutation different haplotype backgrounds were observed, supporting the hypothesis that it occurred de novo on multiple occasions. We also conclude that the high proportion of families with the MSH2 c.388_389del mutation indicates that screening for this alteration as a first step may be cost-effective in the genetic testing of Lynch syndrome suspects of Portuguese ancestry, especially those originating from the north of Portugal.

Abstract
Avaliaram-se as fertilidades e coeficientes de variação (CV) de carneiros Saloios após inseminação artificial (IA) por via cervical com sémen refrigerado (SR) ou congelado (SC). Na 1ª experiência avaliou-se o efeito de duas épocas de IA (primavera vs. outono) sobre a fertilidade, utilizando SR (n=5 carneiros) e de duas épocas de congelação de sémen (outono vs. inverno) sobre a fertilidade de ovelhas inseminadas na primavera utilizando SC (n=3 carneiros). Nas outras experiências avaliaram-se as variações da fertilidade de carneiros, independentemente das épocas de IA ou congelação, utilizando SR e SC (2ª experiência: 4 carneiros comuns; 3ª experiência: 16 e 5 carneiros, respectivamente). Não foram observadas diferenças na fertilidade entre épocas de IA ou congelação de sémen. As fertilidades obtidas com SR foram superiores às do SC (2ª experiência: 51,28 vs. 13,65 %; 3ª experiência: 48,51 vs. 13,04 %). Os CV da fertilidade utilizando SC foram superiores aos do SR (2ª experiência: 41,3 % vs. 13,1 %; 3ª experiência: 38,9 vs. 19,5 %). Os carneiros de raça Saloia podem ser utilizados em programas de IA com SR e SC nas épocas do ano estudadas sem diminuição da fertilidade. O SC originou CV para a fertilidade superior sugerindo diferentes susceptibilidades dos carneiros à congelação.

Abstract
Brunner's gland hyperplasia is a very rare lesion of the duodenum, which is usually asymptomatic and diagnosed incidentally during upper gastrointestinal endoscopy. It can cause gastrointestinal bleeding but hemorrhagic shock is a rare clinical presentation of Brunner's gland hyperplasia. The authors present a case of a patient with hemorrhagic shock due to a bleeding Brunner's gland hyperplasia, treated by urgent laparotomy and polypectomy.

Abstract
BACKGROUND Petersen's space hernia is caused by the herniation of intestinal loops through the defect between the small bowel limbs, the transverse mesocolon and the retroperitoneum, after any type of gastrojejunostomy. The laparoscopic approach facilitates the occurrence of this type of hernia, due to the lack of post-operative adhesions which prevent bowel motility and hence, herniation. CASE REPORT We report the case of a 46 year-old male submitted to an open antrectomy and vagotomy with a Roux-en-Y reconstruction six-years before, for the treatment of bleeding gastric ulcer.He presented with epigastric abdominal pain radiating to the back and alimentary vomiting with a 3 days evolution, with an episode of hematemesis 2 h before admission. His abdomen was bloated and tender at the epigastric region. The laboratory exams revealed mild leucocytosis and CRP elevation with normal pancreatic tests. The abdominal CT scan revealed an intestinal occlusion. An exploratory laparotomy was performed, disclosing an incarcerated Petersen space hernia of the common limb, with obstruction and dilatation of the biliary limb. CONCLUSION The knowledge of this anatomic post-operative defect and a low threshold for diagnosis are crucial to its management, since its nonspecific clinical and laboratory findings. Early operative intervention is warranted in order to avoid the severe complications of bowel necrosis.

Abstract
A variational approach is used to develop a robust numerical procedure for solving the nonlinear Poisson-Boltzmann equation. Following Maggs and Rossetto [Phys. Rev. Lett. 88, 196402 (2002)], we construct an appropriate constrained free energy functional such that its Euler-Lagrange equations are equivalent to the Poisson-Boltzmann equation. This is a formulation that searches for a true minimum in function space, in contrast to previous variational approaches that rather searched for a saddle point. We then develop, implement, and test an algorithm for its numerical minimization, which is quite simple and unconditionally stable. The analytic solution for planar geometry is used for validation. Some results are presented for a charged colloidal sphere surrounded by counterions and optimizations based upon fast Fourier transforms and hierarchical preconditioning are briefly discussed.

METHODS A retrospective study including all infants with CDH at the Hospital de São João, a center that does not provide ECMO support, for the period from 1997 to 2006. Since 2003, a new treatment protocol has been used. RESULTS There were 61 newborns (30 male/31 female) with a birth weight of 2800 g (880 - 3770), and a gestational age of 38 weeks (28 - 41); 46 (75 %) were inborn and 42 (69 %) had a prenatal diagnosis of CDH. There were 2 (3 %) chromosomal anomalies, 3 (5 %) with other congenital anomalies and 1 (2 %) with nonimmune hydrops fetalis. The diaphragmatic defect was left sided in 55 (90 %) cases. Corrective surgery was performed in 43 (70 %) patients. New therapies were used: HFOV 13 % (n = 8); inhaled nitric oxide 13 % (n = 8); and sildenafil 7 % (n = 4). We found that systemic arterial hypotension (p = 0.001), the severity of pulmonary hypertension (p = 0.001), prenatal diagnosis (p = 0.006), birth weight (p = 0.022), female gender (p = 0.029), inborn birth (p = 0.030), arterial pH < 7.35 at admission (p = 0.030), right-sided defect (p = 0.033) and pneumothorax (p = 0.033) to be predictive of mortality. The overall survival rate was 43 % (n = 26), and since 2003 this rate has improved to 61 % for term neonates without other congenital or chromosomal anomalies. CONCLUSIONS Our survival rate for infants with CDH has improved over the last ten years, and this improvement is associated with the use of new therapies such as HFOV, inhaled nitric oxide and sildenafil.

Abstract
Infiltration systems are frequently used as an option to manage urban storm drainage. By reducing flows and volumes in downstream sewers or in surface waters, they decrease the overflows and make it possible to recharge groundwater. They come in various forms with different uses; therefore, their performance is diverse and integrates multiple aspects. Consequently, a multicriteria approach was developed in order to quantify the performance of these systems and to help in decision making problems. For that purpose, a list of performance indicators integrating technical, economical, environmental and social aspects was developed. The performances were defined with the help of a working group composed of engineers from different technical or strategic departments from Greater Lyon and researchers from different fields. The paper presents the last version of the performance indicators tested according to a set of quality requirements: availability of data, relevance, fidelity, precision, sensitivity/robustness. This critical review of the set of indicators has led us to redefine a certain number of indicators, identify numerous biases and allow putting forward general instructions for criterion or indicator construction. The last phase is to propose multicriteria decision aid methods; a procedure using ELECTRE methods should be used.

Abstract
Germline MLH1 and MSH2 mutations are scarce in young colorectal cancer patients with negative family history of the disease. To evaluate the contribution of germline MSH6 mutations to early-onset colorectal cancer, we have analysed peripheral blood of 38 patients diagnosed with this disease before 45 years of age and who presented no family history of hereditary nonpolyposis colorectal cancer-related cancers. Blood samples from 108 healthy volunteers were analysed for those genetic alterations suspected to affect the function of MSH6. Of the seven (18.4%) MSH6 alterations found, we have identified three novel germline mutations, one 8 bp deletion leading to a truncated protein and two missense mutations resulting in the substitution of amino acids belonging to different polarity groups. High-frequency microsatellite instability was found in the patient with the MSH6 deletion, but not in the other 27 carcinomas analysed. No MLH1 promoter methylation was detected in tumour tissue. Our findings suggest that germline MSH6 mutations contribute to a subset of early-onset colorectal cancer. Further studies are warranted to understand the genetic and environmental factors responsible for the variable penetration of MSH6 germline mutations, as well as to identify other causes of early-onset colorectal cancer.

Abstract
BACKGROUND Pouch enlargement and band slippage are the most common late complications of laparoscopic adjustable gastric banding (LAGB). Often, confusion exists among surgeons regarding the denomination or even the treatment of these two different entities. This study aimed to establish the differences in clinical presentation, radiologic features, and management between pouch enlargement and band slippage. The authors hypothesized that pouch enlargement can be managed nonoperatively (via band deflation), that band slippage is an acute complication requiring surgical treatment, and that tailored adjustment allows earlier diagnosis of pouch enlargement in asymptomatic patients. METHODS From March 2001 to December 2004, 516 patients underwent LAGB placement. Barium swallow was performed preoperatively, postoperatively, and during band adjustments ("tailored adjustment"). Pouch enlargement was defined as dilation of the pouch, and band slippage was considered when band and stomach were prolapsed. Four radiologic types of pouch enlargement were considered: band 45 degrees, band 45 degrees with covering of the band, band 0 degrees, and band smaller than 0 degrees. RESULTS A total of 1,600 barium swallows were performed with 516 patients. As a result, pouch enlargement was diagnosed for 61 patients (12%) and band slippage for 12 patients (2%). CONCLUSION In this study, pouch enlargement was found to be a chronic complication that can be managed conservatively with a 77% success rate. Tailored adjustment allows early diagnosis of pouch enlargement, thus preventing adjustments in patients with undiagnosed pouch enlargement. Surgical treatment should be considered when medical treatment fails. By comparison, band slippage is an acute complication that requires surgical treatment in every case (100%).

Abstract
BACKGROUND Laparoscopic Heller myotomy is the standard operation for achalasia. The incidence of esophageal perforation is approximately 5% to 10%. Data about the safety and utility of robotically assisted Heller myotomy (RAHM) are scarce. The aim of this study was to assess the efficacy and safety of RAHM for the treatment of esophageal achalasia. METHODS From a prospectively maintained database, demographic data, symptoms, esophagograms, manometries, and perioperative data from all the RAHMs performed between September 2002 and February 2004 were analyzed. RESULTS A total of 54 patients underwent RAHM, including 26 men. The mean age of these patients was 43 years (range, 14-75 years). Dysphagia was present in 100% of the patients. Of the 54 patients, 26 (48%) had undergone previous treatment including pneumatic dilation (17 patients), Botox injections (4 patients), or both of these treatments (5 patients). The dissection was performed laparoscopically, and the myotomy was performed with robotic assistance. The operative time, including the robot setup time, averaged 162 min (range, 62-210 min). Blood loss averaged 24 ml. No mucosal perforations were observed. The hospital length of stay was 1.5 days. There were no deaths. At 17 months, 93% of the patients had relief of their dysphagia. CONCLUSIONS The findings showed RAHM to be safe and effective, with a 0% incidence of perforation and relief of symptoms for 91% of the patients.

Abstract
BACKGROUND In the United States, the most frequently performed bariatric procedure is the Roux-en-Y gastric bypass (RYGB). Worldwide, the most common operation performed is the laparoscopic adjustable gastric band (LAGB). The expanding use of LAGB is probably driven by the encouraging data on its safety and effectiveness, in contrast to the disappointing morbidity and mortality rates reported for RYGB. The aim of this study was to evaluate the results of LAGB versus RYGB at a single institution. METHODS Between November 2000 and July 2004, 590 bariatric procedures were performed. Of these, 120 patients (20%) had laparoscopic RYGB and 470 patients (80%) had LAGB. A retrospective review was performed. RESULTS In the LAGB group, 376 patients (80%) were female, and the mean age was 41 years (range, 17-65). In the RYGB group, 110 patients (91%) were female, and the mean age was 41 years (range, 20-61). Preoperative body mass index was 47 +/- 8 and 46 +/- 5, respectively (p = not significant). Operative time and hospitalization were significantly shorter in LAGB patients (p < 0.001). Complications and the need for reoperation were comparable in both groups. Weight loss at 12, 18, 24, and 36 months for LAGB and RYGB was 39 +/- 21 versus 65 +/- 13, 39 +/- 20 versus 62 +/- 17, 45 +/- 25 versus 67 +/- 8, and 55 +/- 20 versus 63 +/- 9, respectively. CONCLUSIONS The current study demonstrates that LAGB is a simpler, less invasive, and safer procedure than RYGB. Although mean percentage excess body weight loss (%EBWL) in RYGB patients increased rapidly during the first postoperative year, it remained nearly unchanged at 3 years. In contrast, in LAGB patients weight loss was slower but steady, achieving satisfactory %EBWL at 3 years. Therefore, we believe that LAGB should be considered the initial approach since it is safer than RYGB and is very effective at achieving weight loss.

Abstract
The design process of urban stormwater systems incorporating BMPs involves more complexity unlike the design of classic drainage systems for which just the technique of pipes is likely to be used. This paper presents a simple decision aid methodology and an associated software (AvDren) concerning urban stormwater systems, devoted to the evaluation and the comparison of drainage scenarios using BMPs according to different technical, sanitary, social environmental and economical aspects. This kind of tool is particularly interesting so as to help the decision makers to select the appropriate alternative and to plan the investments especially for developing countries, with important sanitary problems and severe budget restrictions.

Abstract
The authors recently demonstrated that genetic triplication of the SNCA locus causes Parkinson disease. Here it is shown that SNCA triplication results in a doubling in the amount of alpha-synuclein protein in blood. Examination of brain tissue showed a doubling in the level of SNCA message. However, at the protein level in brain, there was a greater effect on deposition of aggregated forms into insoluble fractions than on net expression of soluble alpha-synuclein.

Abstract
UNLABELLED Rhabdomyoma is the most common cardiac neoplasm in neonates. Spontaneous regression of such tumors is common, particularly with smaller lesions, followed by resolution of symptoms. Because most of the tumoral masses regress spontaneously, treatment should primarily be symptomatic, while surgical removal is required only in life-threatening situations. Tuberous sclerosis is found in half of the patients with rhabdomyomas. AIM The aim of our work was to analyze the cases of rhabdomyoma with neonatal presentation in our hospital. METHODS A retrospective review was performed of the hospital records (cardiovascular examination, radiologic and echocardiographic findings, association with tuberous sclerosis, treatment and follow-up) of all neonates admitted, during the last 12 years, with the diagnosis of rhabdomyoma. RESULTS Six patients were found. All diagnoses were established during the first month of life. One third of our population had associated tuberous sclerosis. In three cases the tumors were multiple and the preferential location was the left ventricle. In only one case was surgical removal indicated because of the presence of life-threatening symptoms but the infant's parents refused consent for the procedure. All the children had regression of the tumoral masses. CONCLUSIONS The natural history of rhabdomyomas is one of spontaneous regression with surgical excision being recommended only in the presence of life-threatening symptoms.

Abstract
Superoxide dismutases convert superoxide anions to molecular oxygen and hydrogen peroxide, which, in turn, is metabolized by catalases and/or peroxidases. These enzymes constitute one of the major defense mechanisms of cells against oxidative stress and hence play a role in the pathogenesis of certain bacteria. We previously demonstrated that group B streptococci (GBS) possess a single Mn-cofactored superoxide dismutase (SodA). To analyze the role of this enzyme in the pathogenicity of GBS, we constructed a sodA-disrupted mutant of Streptococcus agalactiae NEM316 by allelic exchange. This mutant was subsequently cis complemented by integration into the chromosome of pAT113/Sp harboring the wild-type sodA gene. The SOD specific activity detected by gel analysis in cell extracts confirmed that active SODs were present in the parental and complemented strains but absent in the sodA mutant. The growth rates of these strains in standing cultures were comparable, but the sodA mutant was extremely susceptible to the oxidative stress generated by addition of paraquat or hydrogen peroxide to the culture medium and exhibited a higher mutation frequency in the presence of rifampin. In mouse bone marrow-derived macrophages, the sodA mutant showed an increased susceptibility to bacterial killing by macrophages. In a mouse infection model, after intravenous injection the survival of the sodA mutant in the blood and the brain was markedly reduced in comparison to that of the parental and complemented strains whereas only minor effects on survival in the liver and the spleen were observed. These results suggest that SodA plays a role in GBS pathogenesis.

Abstract
The capacity of Escherichia coli poly(A) polymerase to adenylylate the 3'-OH residue of a variety of nucleosides, nucleoside 5'-phosphates and dinucleotides of the type nucleoside(5')oligophospho(5')nucleoside is described here for the first time. Using micromolar concentrations of [alpha-32P]ATP, the following nucleosides/nucleotides were found to be substrates of the reaction: guanosine, AMP, CMP, GMP, IMP, GDP, CTP, dGTP, GTP, XTP, adenosine(5')diphospho(5')adenosine (Ap2A), adenosine (5')triphospho(5')adenosine (Ap3A), adenosine(5')tetraphospho(5')adenosine (Ap4A), adenosine(5')pentaphospho(5')adenosine (Ap5A), guanosine(5')diphospho(5') guanosine (Gp2G), guanosine(5')triphospho(5')guanosine (Gp3G), guanosine(5')tetraphospho(5')guanosine (Gp4G), and guanosine(5')pentaphospho(5')guanosine (Gp5G). The synthesized products were analysed by TLC or HPLC and characterized by their UV spectra, and by treatment with alkaline phosphatase and snake venom phosphodiesterase. The presence of 1 mM GMP inhibited competitively the polyadenylylation of tRNA. We hypothesize that the type of methods used to measure polyadenylation of RNA is the reason why this novel property of E. coli poly(A) polymerase has not been observed previously.

Abstract
BACKGROUND Some indices derived from cardiac morphology have been proposed as prognostic factors in fetuses and newborns with congenital diaphragmatic hernia (CDH). These would be of interest in evaluating the risk of pulmonary hypoplasia and the need for surgery in the fetus. The aim of this study was to evaluate the heart-related indices in the nitrofen-induced CDH rat model. METHODS At day 9 1/2 of gestation dated pregnant female Wistar rats received 100 mg of nitrofen. Fetuses were harvested at day 21 1/2 by laparotomy. The fetuses exposed to nitrofen without CDH were defined as the control group (n = 38) while the fetuses exposed to nitrofen with CDH were defined as the CDH group (n = 30). The hearts from both groups were weighed, processed for paraffin embedding and fragmented in serial 7 microns thick transverse sections. In the hearts without cardiac morphological defects the right and the left ventricular cavity volumes were estimated. These allowed calculation of cardioventricular and left-ventricular mass indices. RESULTS In the fetuses without cardiac malformations, no significant difference was found regarding heart-to-body weight ratio, cardioventricular index or left ventricular mass between the study groups. CONCLUSION In this model the presence of CDH was not associated with any alteration in cardiac dimension, in the absence of structural malformations. These results suggest that the indices derived from ventricular morphology should not be used to evaluate the prognosis in fetuses and newborns with CDH.

Abstract
BACKGROUND/PURPOSE The perinatal management and pathophysiology of gastroschisis remain controversial. Large animal experimental models of gastroschisis are inherently limited by expense and length of gestation, making multiple studies and statistical analysis difficult. To address these limitations the authors have developed a model of gastroschisis in the fetal rat. METHODS Twenty-one time-dated pregnant rats underwent laparotomy at 18 (1/2) day's gestational age. The exposed uterus was bathed in ritodrine for tocolysis. The right posterior leg was exteriorized through a hysterotomy, and under a dissecting microscope (16x) the fetal small bowel was exteriorized through a small incision performed on the right lower abdominal quadrant. The amniotic fluid was restored with saline solution and the hysterotomy closed with a purse-string suture. Control fetuses underwent hysterotomy and leg manipulation only. The surgical time was uniformly less than 60 minutes. Fetuses were harvested by cesarean section at 21 (1/2) days' gestational age. Fetal intestine was assessed by microscopic examination, and fetal weight, intestinal length, and intestinal weight per unit length were evaluated. RESULTS There was a significant surgical and anesthetic learning curve, which is not included in this report. After this, the authors achieved a maternal survival of 100% (n = 21). We created gastroschisis in 64 fetuses (58 survivors, 90.6%), and 33 fetuses were only manipulated (30 survivors, 90.9%). The number of induced gastroschisis per pregnant rat varied between 2 and 5 with median of 3. On gross examination, eviscerated intestine appeared dilated, edematous, and covered by peel when compared with control intestine. Fetuses with gastroschisis had significantly reduced body weight (4.1+/-0.5 v 5.6 g +/- 0.5 g) and intestinal length (102+/-19 v 210+/-17 mm) relative to controls, whereas the intestinal weight per unit length (1.75+/-0.29 v 0.71 +/- 0.1 mg/mm) was markedly increased (P<.001). CONCLUSIONS The pathophysiology observed in this experimental model appears to resemble human gastroschisis. In comparison with large animal models, the rat model offers the advantages of low expense, short gestation, littermate controls, and high maternal and fetal survival rates. In addition, there are specific probes and reagents available for application of molecular methodology to clarify the mechanisms responsible for the intestinal damage. This model appears appropriate for future experimental studies on gastroschisis.

Abstract
Oligonucleotides targeting M5 muscarinic receptor mRNA were infused for 6 d into the ventral tegmental area of freely behaving rats trained to bar-press for lateral hypothalamic stimulation. The bar-pressing rate was determined at a range of frequencies each day to evaluate the effects of infusions on reward. M5 antisense oligonucleotide (oligo) infusions increased the frequency required for bar pressing by 48% over baseline levels, with the largest increases occurring after 4-6 d of infusion. Two control oligos had only slight effects (means of 5 and 11% for missense and sense oligos, respectively). After the infusion, the required frequency shifted back to baseline levels gradually over 1-5 d. Antisense oligo infusions decreased M5 receptors on the ipsilateral, but not the contralateral, side of the ventral tegmentum, as compared with a missense oligo. Therefore, M5 muscarinic receptors associated with mesolimbic dopamine neurons seem to be important in brain-stimulation reward.
