Abstract
Investigations of the molecular mechanisms behind detection of short, and particularly ultraviolet, wavelengths in arthropods have relied heavily on studies from insects due to the relative ease of heterologous expression of modified opsin proteins in model organisms like Drosophila. However, species outside of the Insecta can provide information on mechanisms for spectral tuning as well as the evolutionary history of pancrustacean visual pigments. Here we investigate the basis of spectral tuning in malacostracan short wavelength sensitive (SWS) opsins using phylogenetic comparative methods. Tuning sites that may be responsible for the difference between ultraviolet (UV) and violet visual pigment absorbance in the Malacostraca are identified, and the idea that an amino acid polymorphism at a single site is responsible for this shift is shown to be unlikely. Instead, we suggest that this change in absorbance is accomplished through multiple amino acid substitutions. On the basis of our findings, we conducted further surveys to identify spectral tuning mechanisms in the order Stomatopoda where duplication of UV opsins has occurred. Ancestral state reconstructions of stomatopod opsins from two main clades provide insight into the amino acid changes that lead to differing absorption by the visual pigments they form, and likely contribute the basis for the wide array of UV spectral sensitivities found in this order.

Abstract
Overlap of primary studies among systematic reviews (SRs) are one of the main methodological challenges when conducting overviews. If not assessed properly, overlapped primary studies may mislead findings, since they may have a major influence either in qualitative analyses or in statistical weight. Moreover, overlapping SRs may represent the existence of duplicated efforts. Matrices of evidence and the calculation of the overall corrected covered area (CCA) are appropriate methods to address this issue, but they seem to be not comprehensive enough. In this article we present GROOVE (Graphical Representation of Overlap for OVErviews), an easy-to-use tool for overview authors. Starting from a matrix of evidence, GROOVE provides the number of included primary studies and SRs included in the matrix; the absolute number of overlapped and non-overlapped primary studies; and an overall CCA assessment. The tool also provides a detailed CCA assessment for each possible pair of SRs (or "nodes"), with a graphical and easy-to-read representation of these results. Additionally, it includes an advanced optional usage, incorporating structural missingness in the matrix. In this article, we show the details about how to use GROOVE, what results it achieves and how the tool obtains these results. GROOVE is intended to improve the overlap assessment by making it easier, faster, and more friendly for both authors and readers.

Abstract
Transcriptome-based SNP markers were genotyped in a faba bean map to saturate regions bearing QTL for Ascochyta fabae and broomrape and distinguish positional and functional candidates underlying both resistances. Faba bean is an important food crop worldwide. Marker-assisted selection for disease resistance is a top priority in current faba bean research programs, with pathogens such as Ascochyta fabae and broomrape (Orobanche crenata) being among the major constraints in global faba bean production. However, progress in genetics and genomics in this species has lagged behind that of other grain legumes. Although genetic maps are available, most markers are not in or are too distant from target genes to enable an accurate prediction of the desired phenotypes. In this study, a set of SNP markers located in gene coding regions was selected using transcriptomic data. Ninety-two new SNP markers were genotyped to obtain the most complete map reported so far in the 29H × Vf136 faba bean population. Most of the QTL regions previously described in this cross were enriched with SNP markers. Two QTLs for O. crenata resistance (Oc7 and Oc8) were confirmed. Oc7 and Oc10 located nearby a QTL for A. fabae resistance suggested that these genomic regions might encode common resistance mechanisms and could be targets for selection strategies against both pathogens. We also confirmed three regions in chromosomes II (Af2), III (Af3) and VI associated with Ascochyta blight resistance. The QTLs ratified in the present study are now flanked by or include reliable SNP markers in their intervals. This new information provides a valuable starting point in the search for relevant positional and functional candidates underlying both types of resistance.

Abstract
A 23-year-old man presented with a chronic anterior chest wall wound. Previously he had a split thickness skin graft in the area in where the wound bed had become infected, developing a thick purulent drainage. The infected skin graft was excised. Histologic examination of the failed graft revealed skin with surface ulceration, focal abscess formation, deep penetrating acute and chronic inflammation with numerous eosinophils, and granulomatous changes demonstrating a foreign body-type reaction to fungal hyphae (highlighted by periodic acid-Schiff staining, Figures 1A-E). The patient's past medical history included scoliosis, acute lower back pain, right shoulder degenerative joint disease, atopic dermatitis, lymphadenitis, rhonchi, insomnia, depression, and a long history of recurrent infections, particularly cutaneous staphylococcal and candida albicans infections, often accompanied by a purulent drainage. Review of the patient's laboratory studies revealed chronically elevated alkaline phosphatase, with highly elevated serum IgE (2,922 IU/ml) and eosinophilia (925/μL3) since childhood. Other lab studies were unremarkable, except for episodic elevations of the white blood cell count. The patient's family history was largely unremarkable and the patient's parents and siblings had no histories of unusual infections.

Abstract
For the first time the putative NSP2 gene in chickpea has been identified using pairs of NILs differing for the Rn1 / rn1 nodulation gene that was located in LG5 of chickpea genetic map. An intraspecific cross between the mutant non-nodulating genotype PM233, carrying the recessive gene rn1, and the wild-type CA2139 was used to develop two pairs of near-isogenic lines (NILs) for nodulation in chickpea. These pairs of NILs were characterized using sequence tagged microsatellite site (STMS) markers distributed across different linkage groups (LGs) of the chickpea genetic map leading to the detection of polymorphic markers located in LG5. Using this information, together with the genome annotation in Medicago truncatula, a candidate gene (NSP2) known to be involved in nodulation pathway was selected for mapping in chickpea. The full length sequence obtained in chickpea wild-type (CaNSP2) was 1,503 bp. Linkage analysis in an F3 population of 118 plants derived from the cross between the pair of NILS NIL7-2A (nod) × NIL7-2B (non-nod) revealed a co-localization between CaNSP2 and Rn1 gene. These data implicate the CaNSP2 gene as a candidate for identity to Rn1, and suggest that it could act in the nodulation signaling transduction pathway similarly to that in other legumes species.

Abstract
High-altitude hypoxia generates spermiogram impairment due to germinal epithelium, Leydig cells, sperm and seminal plasma alterations, but precise mechanisms involved are unknown. The objective of this work was to analyse the effect of normobaric hypoxia on the morphology of testicular interstitium and some associated molecular and hormonal factors. Twenty-four mice were exposed to normobaric hypoxia (8.1% inspired oxygen fraction) during 20 days. The effects on body weight, testicular weight, vascularisation, testosterone, HIF1-α and VEGF were analysed at different periods of exposure and compared to controls. Hypoxic mice had lower body weight than mice kept in normoxia. Testicular weight raised significantly the 1st day, but remained normal during the rest of experiment. Number of blood vessels per field and mean diameter of vessels were higher in hypoxic mice. Plasmatic and testicular testosterone raised during first 24 h of hypoxia, but decreased on the 5th day. Vascular/interstitial ratio (proportion of interstice occupied by blood vessels) duplicated at the end of the experiment. Most substantial early effects of hypoxia were testicular oedema, increase in number and diameter of blood vessels and elevation of plasmatic and testicular testosterone. Normobaric hypoxia generates similar effects to those induced by hypobaric hypoxia.

Abstract
Two alleles of a chickpea (Cicer arietinum L.) ethylene receptor-like sequence (CaETR-1) were sequence-characterized using synteny analysis with genome sequences of Medicago truncatula L. The full length of the sequence obtained in the accession FLIP84-92C resistant to ascochyta blight (CaETR-1a) span 4,428 bp, including the polyadenylation signal in the 3'-untranslated region (UTR), whereas it has a 730 bp deletion in the 3'-UTR region in the susceptible accession PI359075 (CaETR-1b). The deduced protein belongs to subfamily II of the ethylene receptors and contains all the domains that define EIN4 homologs in Arabidopsis. The EIN4-like sequence (CaETR-1) has been mapped using a recombinant inbred line (RIL) population derived from an intraspecific cross between ILC3279 and WR315, resistant and susceptible to blight, respectively. The locus was located in LGIVa of the genetic map, flanked by markers NCPGR91 and GAA47 (at distances of 11.3 and 17.9 cM, respectively). This is the first potentially functional sequence identified under a QTL peak for ascochyta blight resistance in chickpea (QTL(AR1)). This EIN4-like (CaETR-1) sequence explained up to 33.8% of the total phenotypic variation. This sequence could be directly related to blight resistance, together with other QTLs that have been found to be involved in resistance to this major chickpea disease.

Abstract
Placentation starts with the formation of a spheroidal trophoblastic shell surrounding the embryo, thus facilitating both implantation into the uterine stroma and contact with maternal blood. Although it is known that diabetes increases the placental size and weight, the mechanisms responsible for this alteration are still poorly understood. In mammals, cellular proliferation occurs in parallel to placental development and it is possible that diabetes induces abnormal uncontrolled cell proliferation in the placenta similar to that seen in other organs (e.g. retina). To test this hypothesis, the objective of this work was to determine cell proliferation in different regions of the placenta during its development in a diabetic rat model. Accordingly, diabetes was induced on day 2 of pregnancy in Wistar rats by a single injection of alloxan (40 mg/kg i.v.). Placentas were collected on days 14, 17, and 20 postcoitum. Immunoperoxidase was used to identify Ki67 nuclear antigen in placental sections. The number of proliferating cells was determined in the total placental area as well as in the labyrinth, spongiotrophoblast and giant trophoblast cell regions. During the course of pregnancy, the number of Ki67 positive cells decreased in both control and diabetic rat placentas. However, starting from day 17 of pregnancy, the number of Ki67 positive cells in the labyrinth and spongiotrophoblast regions was higher in diabetic rat placentas as compared to control. The present results demonstrate that placentas from the diabetic rat model have a significantly higher number of proliferating cells in specific regions of the placenta and at defined developmental stages. It is possible that this increased cell proliferation promotes thickness of the placental barrier consequently affecting the normal maternal-fetal exchanges.

Abstract
Understanding the host response to Uromyces sp., the causal agent of rust in many crop species, is crucial in elucidating the specific biology of rust resistance. In an attempt to unravel the Medicago truncatula-U. striatus interaction, we performed a global analysis of transcription factor (TF) expression in resistant and susceptible accessions of the model plant M. truncatula during infection with U. striatus. For this purpose, an established qPCR platform was applied, consisting of specific primer pairs for more than 1,000 predicted TF genes. A total of 107 putative TF genes out of the 1,084 studied were differentially expressed. Thirteen of the TFs that were differentially expressed between resistant and susceptible genotypes are known to be relevant in cellular defense. These data suggest that resistance could be mediated both by genes that are constitutively expressed and by genes, which are activated/repressed when plants are inoculated. These defense related TFs sequences were amplified in chickpea DNA with the aim of determining the location of these genes on the genetic map of this crop and identifying possible DNA regions involved in resistance mechanisms.

Abstract
Four pairs of near-isogenic lines (NILs) of chickpea with resistance/susceptibility to Fusarium oxysporum f. sp. ciceris (Foc) have been developed in this study. These lines were produced by searching in advanced recombinant inbred lines (RILs) that are segregating for Foc race 5 based on a phenotypic screening. The sequence tagged microsatellite (STMS) marker TA59, closely linked to wilt resistance genes on linkage group 2 (LG2) of the chickpea map, was used to assist the selection of resistant or susceptible genotypes. The NILs were also characterized for disease reaction to Foc races 1A, 2, 3 and 4. Resistance, susceptibility and slow wilting reactions were found in these NILs. Our results suggest that more than one gene controls the resistance to race 5. Combination of the major gene foc-5 linked to TA59 with other gene/s appears to be required to complete resistance, and the absence of these unknown genes leads to slow wilting reactions. The independent differential responses to races 2 and 3 observed in three NILs could be explained as recombination events. This result suggests that foc-2 and foc-3 are delimiting points at opposite ends of a genomic region that includes the remaining foc genes and the TA59 marker. This set of NILs has great potential for studying the genetics and mechanisms of wilt resistance. In addition, the NIL RIP8-94-11 can be used as differential line for Foc race 3; it showed a clear resistance reaction to race 3 and susceptibility to the other Foc races.

Abstract
OBJECTIVES Patients who survive an episode of acute necrotizing pancreatitis may develop endocrine and exocrine pancreatic functional impairment; often these patients have undergone pancreatic surgery during the acute episode. Aim of this study is to report the results of a long-term follow-up of patients recovering from an episode of acute necrotizing pancreatitis which had not been treated surgically during the index hospital admission. DESIGN AND SUBJECTS Sixty-five consecutive patients enrolled between January 1990 and December 1993, prospectively followed through December 2006. RESULTS Median follow-up period was 179.5 months (range 156-203). 40 patients (61.5%) who completed follow-up were analysed. Endocrine function: 2 patients (5%) were diabetic before the pancreatitis episode, and 6 (15.7%) developed overt diabetes; diabetes appeared within the 3rd year after acute pancreatitis in 2 patients, between the 3rd and 4th year in 2 patients, and between the 5th and 6th year in the last 2 patients. Exocrine function: 9 patients (22.5%) showed fecal elastase impairment; in all patients ultrasound was normal and fecal elastase returned above the normal limit during follow-up. CONCLUSIONS After an episode of acute necrotizing pancreatitis treated without surgery, the endocrine and exocrine function is not frequently impaired after long-term follow-up. Reduction in exocrine function is transient and complete recovery is achieved in all patients within a few years.

Abstract
BACKGROUND Septic arthritis (SA) of the sternoclavicular joint (SCJ) is an uncommon form of arthritis, generally described in patients with predisposing risk factors such as primary or secondary immunosuppressive disorders, systemic or localized infections and central venous catheters. More rarely the infection occurs in patients without these risk factors, thus rendering difficult an early diagnosis. MATERIAL AND METHODS We report two cases of SA of the SCJ occurred in two patient, without known predisposing risk factors, hospitalized in our Internal Medicine Unit. RESULTS The clinical characteristics didn't significantly differ from clinical course of the disease occurring in patients with predisposing risk factors. Imaging techniques were useful to suspect diagnosis, but only fine-needle aspiration biopsy with culture of specimens leaded to identify the pathogen and its antibiotic sensitivity (in both patients Staphylococcus aureus). One patient was treated with surgical adequate curettage, drainage and intravenous methicillin, while the other one received only medical treatment with intravenous teicoplanin and ceftazidime. The outcome was uneventful with a complete recovery in both cases. CONCLUSIONS Even if SA of SCJ is uncommon in subjects without predisposing risk factors, the clinician must have a high index of suspicion to consider this disease in differential diagnosis of arthritis also in previously healthy subjects with negative or unsettling instrumental investigations. In fact, prompt diagnosis is essential to obtain a successful outcome, avoiding the prolongation of the hospitalization and the sequelae of a chronic infection.

Abstract
When a stimulus appears in a previously cued location several hundred milliseconds after the cue, the time required to detect that stimulus is greater than when it appears in an uncued location. This increase in detection time is known as inhibition of return (IOR). It has been suggested that IOR reflects the action of a general attentional mechanism that prevents attention from returning to previously explored loci. At the same time, the robustness of IOR has been recently disputed, given several failures to obtain the effect in tasks requiring discrimination rather than detection. In a series of eight experiments, we evaluated the differences between detection and discrimination tasks with regard to IOR. We found that IOR was consistently obtained with both tasks, although the temporal parameters required to observe IOR were different in detection and discrimination tasks. In our detection task, the effect appeared after a 400-msec delay between cue and target, and was still present after 1,300 msec. In our discrimination task, the effect appeared later and disappeared sooner. The implications of these data for theoretical accounts of IOR are discussed.

Abstract
Genital herpes is one of the sexually transmitted diseases that can have serious long-term psychological and physical consequences for young adults who contract the disease. Because of the chronic, reoccurring nature of genital herpes, these young adults need education about the transmission of the herpes virus and about safer sexual practices in addition to emotional support. Psychoeducational groups have shown to be a nursing intervention that can effectively provide this education and support. Yet community health nurses may not be knowledgeable about or comfortable with using this type of intervention. In this article we explain the process of training community health nurses to be nurse facilitators who conduct psychoeducational groups for young adults with genital herpes. The training consisted of a 1-day workshop and three follow-up sessions. The content and format of this training workshop and the follow-up sessions is presented in addition to recommendations to enhance this nursing intervention.
