Abstract
Converting minor-approach-only stop (MAS) intersections to all-way-stop (AWS) intersections is a prevailing safety countermeasure in North American urban areas. Although the general population positively perceives the installation of stop-signs in residential areas, little research has investigated the impact of AWS on road safety and road user behaviour. This paper investigated the safety effectiveness of converting MAS to AWS intersections using an observational before and after approach and surrogate measures of safety. More specifically, the safety impacts of AWS conversion were investigated using multiple indicators, including vehicle speed measures, vehicle-pedestrian, vehicle-cyclist, vehicles-vehicle interactions as well as yielding rates before and after the treatment implementation. A multi-level regression approach was adopted to determine the effect of stop signs controlling for built environments, traffic exposure, and intersection geometry factors as well as site-specific unobserved heterogeneity. A unique sample of 31 intersections were used in this before-after study. From this sample, video data were collected before and after implementing AWS. In total, 245 h of video were automatically processed and corrected using a specialized computer vision software. More than 68,000 (37,668 before and 31,305 after AWS treatment) road user trajectories were obtained from 104 approaches. The results show that the conversion of MAS to AWS intersections significantly decreased vehicle speed and increased post-encroachment time. This work also shows that implementing AWS significantly increased the yielding rates from 45.7% to 76.7% in MAS conditions and reduced the average speed of motor-vehicles. Using multi-level regression model, it is estimated that when the intersection was converted from MAS to AWS, the minimum speed in the major approaches was reduced by 60.0%.

Abstract
Genome studies of chronic lymphocytic leukemia (CLL) have revealed the remarkable subclonal heterogeneity of the tumors, but the clinical implications of this phenomenon are not well known. We assessed the mutational status of 28 CLL driver genes by deep-targeted next-generation sequencing and copy number alterations (CNA) in 406 previously untreated patients and 48 sequential samples. We detected small subclonal mutations (0.6-25% of cells) in nearly all genes (26/28), and they were the sole alteration in 22% of the mutated cases. CNA tended to be acquired early in the evolution of the disease and remained stable, whereas the mutational heterogeneity increased in a subset of tumors. The prognostic impact of different genes was related to the size of the mutated clone. Combining mutations and CNA, we observed that the accumulation of driver alterations (mutational complexity) gradually shortened the time to first treatment independently of the clonal architecture, IGHV status and Binet stage. Conversely, the overall survival was associated with the increasing subclonal diversity of the tumors but it was related to the age of patients, IGHV and TP53 status of the tumors. In conclusion, our study reveals that both the mutational complexity and subclonal diversity influence the evolution of CLL.

Abstract
IntroductionThe new edition of the DSM has introduced some changes involving differences, sometimes significant, in the conceptualization and classification of mental pathology. One of the most important has been the case of mental retardation.Objectives and aimsDiscuss, with a clinical and pragmatic perspective, the relevance of those changes in the diagnosis and classification of mental retardation in DSM.MethodsA 45-year-old woman diagnosed with mental retardation is admitted in a psychiatric rehabilitation unit for behavioral disorders and psychotic symptoms. Once controlled the symptoms and studied the patient, a disability not corresponding with the diagnosis presented (mild mental retardation according to DSM IV) is shown. Clinicians start a reevaluation of the diagnosis.ResultsA comprehensive rehabilitation program according to the pathology and deterioration of the patient is designed. With the diagnosis review is possible to find new resources and community programs, better fit for the patient needs.ConclusionsDSM V changes in mental retardation diagnosis and classification allows a better perspective of the disease and its impact of functionality.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionSexual function is important for patients’ well-being but it is a common side effect of SSRI and SNRI, included desvenlafaxine.Objectives and aimsEvaluate incidence and characteristics of sexual dysfunction caused by desvenlafaxine in the clinical practice.MethodsOne hundred and thirty-three patients with recently introduced desvenlafaxine treatment are recruited from Barakldo and Uribe-Kosta Mental Health Centres in Biscay, Spain. UKU scale is administered to measure sexual side effects. Statistical analysis is performed using SPSS v.22.ResultsSexual dysfunction is observed in 5 patients (3.7%) at 50 and 100 mg/d (2 and 3 patients, respectively) desvenlafaxine doses. Two patients (1.5%) have experimented more than one sexual side effect. Regarding gender differences, the most frequent sexual dysfunctions are diminished sexual desire (5.5%) and erectile dysfunction (5.5%) in men and orgasmic dysfunction (1.2%) in women (P-values are 0.034; 0.034 and 0.408, respectively). Discontinuation is decided in 60% of patients.ConclusionsDesvenlafaxine has a well-tolerated sexual side effect profile in general population. There are some gender-related differences both in presentation and perception, as it has been described with other drugs, and this should be taken into account by prescriptors.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Cherry trees from Spain affected by cherry leaf scorch (CLS), a fungal disease proposed to be caused by Apiognomonia erythrostoma, show symptoms (translucent-chlorotic leaf spots evolving into rusty areas) very similar to those of cherry chlorotic rusty spot disease (CCRS) and Amasya cherry disease, reported in Italy and Turkey, respectively. The three maladies are closely associated with 10-12 double-stranded viral RNAs, and CCRS is additionally associated with two cherry small circular RNAs (cscRNA1 and cscRNA2). Here, we report that a small viroid-like RNA similar to the CCRS-associated cscRNA1 is also present in CLS-affected trees, thus extending the link between the two diseases. Both CLS and CCRS cscRNA1 elements have common features, including sequence identity (88 %), a predicted quasi rod-like conformation with short bifurcations at both termini, and the presence of hammerhead ribozymes in the strands of both polarities. However, cscRNA2, apparently derived from cscRNA1 by deletion of a short hairpin, was not detected in CLS-affected material. Although the biological nature of cscRNAs is unknown, the identification of at least cscRNA1 in different cherry cultivars and in two distinct geographic areas (Spain and Italy), always in close association with the same mycoviral dsRNAs, supports that these viroid-like RNAs could be satellite RNAs.

Here, we report that a small viroid-like RNA similar to the CCRS-associated cscRNA1 is also present in CLS-affected trees, thus extending the link between the two diseases. Both CLS and CCRS cscRNA1 elements have common features, including sequence identity (88%), a predicted quasi rod-like conformation with short bifurcations at both termini, and the presence of hammerhead ribozymes in the strands of both polarities. However, cscRNA2, apparently derived from cscRNA1 by deletion of a short hairpin, was not detected in CLS-affected material. Although the biological nature of cscRNAs is unknown, the identification of at least cscRNA1 in different cherry cultivars and in two distinct geographic areas (Spain and Italy), always in close association with the same mycoviral dsRNAs, supports that these viroid-like RNAs could be satellite RNAs.

Abstract
The autism susceptibility locus on human chromosome 7q32 contains the maternally imprinted MEST and the non-imprinted COPG2 and TSGA14 genes. Autism is a disorder of the 'social brain' that has been proposed to be due to an overbalance of paternally expressed genes. To study regulation of the 7q32 locus during anthropoid primate evolution, we analyzed the methylation and expression patterns of MEST, COPG2, and TSGA14 in human, chimpanzee, Old World monkey (baboon and rhesus macaque), and New World monkey (marmoset) cortices. In all human and anthropoid primate cortices, the MEST promoter was hemimethylated, as expected for a differentially methylated imprinting control region, whereas the COPG2 and TSGA14 promoters were completely demethylated, typical for transcriptionally active non-imprinted genes. The MEST gene also showed comparable mRNA expression levels in all analyzed species. In contrast, COPG2 expression was downregulated in the human cortex compared to chimpanzee, Old and New World monkeys. TSGA14 either showed no differential regulation in the human brain compared to chimpanzee and marmoset or a slight upregulation compared to baboon. The human-specific downregulation supports a role for COPG2 in the development of a 'social brain'. Promoter methylation patterns appear to be more stable during evolution than gene expression patterns, suggesting that other mechanisms may be more important for inter-primate differences in gene expression.

Abstract
The human brain is distinguished by its remarkable size, high energy consumption, and cognitive abilities compared to all other mammals and non-human primates. However, little is known about what has accelerated brain evolution in the human lineage. One possible explanation is that the appearance of advanced communication skills and language has been a driving force of human brain development. The phenotypic adaptations in brain structure and function which occurred on the way to modern humans may be associated with specific molecular signatures in today's human genome and/or transcriptome. Genes that have been linked to language, reading, and/or autism spectrum disorders are prime candidates when searching for genes for human-specific communication abilities. The database and genome-wide expression analyses we present here revealed a clustering of such communication-associated genes (COAG) on human chromosomes X and 7, in particular chromosome 7q31-q36. Compared to the rest of the genome, we found a high number of COAG to be differentially expressed in the cortices of humans and non-human primates (chimpanzee, baboon, and/or marmoset). The role of X-linked genes for the development of human-specific cognitive abilities is well known. We now propose that chromosome 7q31-q36 also represents a hot spot for the evolution of human-specific communication abilities. Selective pressure on the T cell receptor beta locus on chromosome 7q34, which plays a pivotal role in the immune system, could have led to rapid dissemination of positive gene variants in hitchhiking COAG.

Abstract
The CES-D is widely used for the assessment of depressive symptoms in the adult population. However, few studies have been performed to assess the utility of this scale in an older population with cognitive impairment. The factor structure of the Spanish version of the CES-D was examined in an observational, cross sectional study in 623 older adults (M = 72.74 years; SD = 7.7). The validity of the scale was determined in two samples of older adults, one comprising 162 participants with cognitive impairment (M = 76.73 years; SD = 8.1) and one with 58 participants without cognitive impairment (M = 74.64 years; SD = 9.0). The results confirm previous results of a four factor structure. With regard to the validity of the scale, in the group with cognitive impairment the area under the ROC curve is 0.84 (95% CI: 0.77-0.89) and the cut-off point for possible depression is 13, while in the group without cognitive impairment the area is 0.90 (95% CI: 0.79-0.96) and the optimal cut-off point is 28. These results show that the Spanish version of the CES-D is a valid instrument for the identification of depression in older adults with and without cognitive impairment.

Abstract
BACKGROUND Immediate-type hypersensitivity reactions to quinolones are rare. Some reports describe the presence of cross-reactivity among different members of the group, although no predictive pattern has been established. No previous studies confirm or rule out cross-reactivity between levofloxacin and other quinolones.Therefore, a joint study was designed between 2 allergy departments to assess cross-reactivity between levofloxacin and other quinolones. MATERIAL AND METHODS We studied 12 patients who had experienced an immediate-type reaction (4 anaphylaxis and 8 urticaria/angioedema) after oral administration of quinolones. The culprit drugs were as follows: ciprofloxacin (5), levofloxacin (4), levofloxacin plus moxifloxacin (1), moxifloxacin (1), and norfloxacin (1). Allergy was confirmed by skin tests and controlled oral challenge tests with different quinolones. The basophil activation test (BAT) was applied in 6 patients. RESULTS The skin tests were positive in 5 patients with levofloxacin (2), moxifloxacin (2), and ofloxacin (2). BAT was negative in all patients (6/6). Most of the ciprofloxacin-reactive patients (4/5) tolerated levofloxacin. Similarly, 3 of 4 levofloxacin-reactive patients tolerated ciprofloxacin. Patients who reacted to moxifloxacin and norfloxacin tolerated ciprofloxacin and levofloxacin. CONCLUSIONS Our results suggest that skin testing and BAT do not help to identify the culprit drug or predict cross-reactivity. Oral challenge testing is the only way to confirm tolerance to a quinolone before prescribing it as a safe alternative. Levofloxacin could be a safer alternative in cases of reaction to first-, second-, or fourth-generation quinolones.

Abstract
Although rare, anaphylactic reactions induced by proton pump inhibitors have been reported. The presence of cross-reactivity between different members of the group is not clear. We studied 9 patients with adverse reactions to omeprazole. Clinical symptoms appeared immediately in 8 patients and after 4 hours in 1. Symptoms ranged from urticaria/angioedema in 7 cases to anaphylaxis in 2 cases. Skin prick tests and oral controlled challenge tests with omeprazole, lansoprazole, and pantoprazole were performed. Skin prick or intradermal tests with omeprazole were positive in 8 patients. Four were also positive to pantoprazole. Prick tests with lansoprazole were always negative. Lansoprazole was administered to all 9 patients, with good tolerance in 8. Only 3 patients were challenged with pantoprazole and developed widespread urticaria. We present 9 patients with immunoglobulin E-mediated allergy to omeprazole. In most of our cases, lansoprazole proved to be a good alternative treatment.

Abstract
This open label clinical study provides updated evaluation of the strategy of single unit cord blood transplants (CBTs) with co-infusion of third-party donor (TPD) mobilized hematopoietic stem cells (MHSC). Fifty-five adults with high-risk hematological malignancies, median age 34 years (16-60 years) and weight 70 kg (43-95 kg), received CBTs (median 2.39 x 10(7) total nucleated cell (TNC) per kg and 0.11 x 10(6) CD34+ per kg) and TPD-MHSC (median 2.4 x 10(6) CD34+ per kg and 3.2 x 10(3) CD3+ per kg). Median time to ANC and to CB-ANC >0.5 x 10(9)/l as well as to full CB-chimerism was 10, 21 and 44 days, with maximum cumulative incidences (MCI) of 0.96, 0.95 and 0.91. Median time to unsupported platelets >20 x 10(9)/l was 32 days (MCI 0.78). MCI for grades I-IV and III-IV acute GVHD (aGVHD) were 0.62 and 0.11; 12 of 41 patients (29%) who are at risk developed chronic GVHD, becoming severely extensive in three patients. Relapses occurred in seven patients (MCI=0.17). The main causes of morbi-mortality were post-engraftment infections. CMV reactivations were the most frequent, their incidence declining after the fourth month. Five-year overall survival and disease-free survival (Kaplan-Meier) were 56 % and 47% (63% and 54% for patients <or=40 years). In conclusion, CBT with single units of relatively low cell content and 0-3 HLA mismatches is feasible as a first choice option for adult patients who lack a readily available adequate adult donor.

Abstract
The pore-forming subunits of canonical voltage-gated sodium and calcium channels are encoded by four repeated domains of six-transmembrane (6TM) segments. We expressed and characterized a bacterial ion channel (NaChBac) from Bacillus halodurans that is encoded by one 6TM segment. The sequence, especially in the pore region, is similar to that of voltage-gated calcium channels. The expressed channel was activated by voltage and was blocked by calcium channel blockers. However, the channel was selective for sodium. The identification of NaChBac as a functionally expressed bacterial voltage-sensitive ion-selective channel provides insight into both voltage-dependent activation and divalent cation selectivity.

Abstract
In this report we analyse the presenting features of a series of patients diagnosed with Waldenström macroglobulinaemia (WM) in Spain over the last 10 years. Criteria for diagnosis required a serum monoclonal IgM protein > or = 30 g/l and > 20% bone marrow lymphocytes. Two hundred and seventeen patients were included in the study, with a median age of 69 years and male/female ratio of 2:1. The most common symptoms at diagnosis were anaemia (38%), hyperviscosity (31%), B symptoms (23%), bleeding (23%) and neurological symptoms (22%). Sixty-one patients (27%) were asymptomatic at diagnosis and, to date, 32 of them have not received chemotherapy. Variables predicting a shorter survival free of therapy were haemoglobin < 12.5 g/dl and high beta2microglobulin (beta2M). The 83% of patients who did receive treatment were distributed as follows: chlorambucil/prednisone (43%), intermittent chlorambucil (11%), continuous chlorambucil (26%), cyclophosphamide/vincristine/prednisone (COP, 13.5%) and other (6.5%). Response to therapy was complete in 2%, partial in 48% and minor in 10%. Finally, 28% and 13% of patients presented stable and progressive disease, respectively, which was more common among patients treated with COP. Progression-free survival was 43% at 5 years, with three independent predictors for shorter progression-free survival (PFS): COP treatment, age > 65 and B symptoms at diagnosis. The 10-year projected overall survival (OS) was 55%. The two most frequent causes of death were development of second malignancies (31%), or infections (19%). The two main variables predicting a poor OS were hyperviscosity and high beta2M. In summary, this study favours the use of chlorambucil-based therapy as the standard treatment for WM, and describes a subset of patients who should be considered as suffering a smouldering form and who therefore do not require treatment for a long period of time.

Abstract
Calcium and cyclic nucleotides have crucial roles in mammalian fertilization, but the molecules comprising the Ca2+-permeation pathway in sperm motility are poorly understood. Here we describe a putative sperm cation channel, CatSper, whose amino-acid sequence most closely resembles a single, six-transmembrane-spanning repeat of the voltage-dependent Ca2+-channel four-repeat structure. CatSper is located specifically in the principal piece of the sperm tail. Targeted disruption of the gene results in male sterility in otherwise normal mice. Sperm motility is decreased markedly in CatSper-/- mice, and CatSper-/- sperm are unable to fertilize intact eggs. In addition, the cyclic-AMP-induced Ca2+ influx is abolished in the sperm of mutant mice. CatSper is thus vital to cAMP-mediated Ca2+ influx in sperm, sperm motility and fertilization. CatSper represents an excellent target for non-hormonal contraceptives for both men and women.

Abstract
The generation of unlimited quantities of neural stem and/or progenitor cells derived from the human brain holds great interest for basic and applied neuroscience. In this article we critically review the origins and recent developments of procedures developed for the expansion, perpetuation, identification, and isolation of human neural precursors, as well as their attributes. Factors influencing their in vitro properties, both under division and after differentiation conditions, are evaluated, with the aim of identifying properties common to the different culture systems reported. This analysis suggests that different culture procedures result in cells with different properties, or even in different cells being isolated. With respect to in vivo performance, present evidence obtained in rodents indicate that cultured human neural precursors, in general, are endowed with excellent integrative properties. Differentiation of the implanted cells, in particular in the case of adult recipients, seems not to be complete, and functionality still needs to be demonstrated. In relation to gene transfer and therapy, aspects currently underexplored, initial data support the view that human neural stem and progenitor cells may serve a role as a platform cell for the delivery of bioactive substances to the diseased CNS. Although a large deal of basic research remains to be done, available data illustrate the enormous potential that human neural precursors isolated, expanded, and characterized in vitro hold for therapeutic applications. In spite of this potential, maintaining a critical view on many unresolved questions will surely help to drive this research field to a good end, that is, the development of real therapies for diseases of the human nervous system.

Abstract
Because of their ability to generate all the cell types in the nervous system, neural stem cells are promising candidates for the development of cellular and genetic therapies for nervous system disorders and, in particular, neurodegenerative diseases. In recent years, researchers have discovered ways of expanding and perpetuating these cells in culture, as well as different sources for these tissue-specific stem cells, ranging from embryonic to adult tissue, and also from human pluripotent stem cells. Current efforts are oriented to the understanding of the molecular mechanisms controlling their fate decisions, their genetic engineering, and how to harness their potential to make them useful from a therapeutic point of view.

Abstract
Human neural stem cells (HNSCs) may serve as a cellular vehicle for molecular therapies as well as for cell replacement in the human CNS. The survival, integration, and differentiation of HNSC.100, a multipotent cell line of HNSCs (A. Villa et al. (2000), Exp. Neurol. 161, 67-84), conditionally perpetuated by genetic and epigenetic means, was investigated after transplantation to the striatum and substantia nigra of the adult, intact rat brain. These are two key regions in the mammalian brain involved in the control of voluntary movement and motor coordination, among other functions. Soon after transplantation (1 week), the cells had already integrated in a nondisruptive manner into the surrounding tissue and migrated out of the implantation site to different distances depending on graft location (in the range of 0.5-2.5 mm). Cell migration was markedly more extensive in the striatum, where the cells colonized the whole extent of the caudate-putamen, than in the substantia nigra region. The engrafted cells completely downregulated the stem cell marker nestin and, due to their multipotential nature, differentiated and expressed mature neural markers. As expected from cells grafted into nonneurogenic regions of the intact brain, the majority of differentiated cells expressed GFAP (astroglia), but expression of other markers, like GalC (oligodendroglia) and MAP2, beta-tubulin III, NeuN, and NSE (for mature neurons) could also be detected. These results demonstrate that genetically perpetuated HNSCs, once transplanted, find residence in the host brain, where they differentiate, generating mature neural cells in the host, chimeric, adult mammalian brain. HNSCs cell lines may be a highly useful model for the development of humanized systems for cell replacement and/or gene transfer to the CNS, which will likely be strong candidates for future therapeutic application in human neurodegenerative conditions.

Abstract
Targeted expression of foreign genes to the peripheral nervous system is interesting for many applications, including gene therapy of neuromuscular diseases, neuroanatomical studies, and elucidation of mechanisms of axonal flow. Here we describe a microneurosurgical technique for injection of replication-defective viral vectors into dorsal root ganglia (DRG). Adenovirus- and adeno-associated virus-based vectors with transcriptional competence for DRG neurons led to expression of the gene of interest throughout the first neuron of the sensory system, from the distal portions of the respective sensory nerve to the ipsilateral nucleus gracilis and cuneatus, which contains the synapses to the spinothalamic tracts. Use of Rag-1 ablated mice, which lack all B and T lymphocytes, allowed for sustained expression for periods exceeding 100 days. In immunocompetent mice, long-term (52 days) expression was achieved with similar efficiency by using adeno-associated viral vectors. DRG injection was vastly superior to intraneural injection into the sciatic nerve, which mainly transduced Schwann cells in the vicinity of the site of inoculation site but only inefficiently transduced nerve fibers, whereas i.m. injection did not lead to any significant expression of the reporter gene in nerve fibers. The versatile and efficient transduction of genes of interest should enable a wide variety of functional studies of peripheral nervous system pathophysiology.

Abstract
PURPOSE Accurate presurgical assessment of tumor size in breast cancer is important for choosing appropriate treatment. We retrospectively compared presurgical sonographic measurements of tumor size with postsurgical measurements of size and other variables. METHODS In 174 cases, tumor size was measured by sonography before surgery, and those measurements were compared with values obtained by histopathologic examination of the specimens. The histologic type and grade, the number of lesions, and the presence of an extensive intraductal component also were considered in the intramodal correlations of tumor size. RESULTS Sonographic measurements of tumor size correlated well with size measured after surgery (r = 0.72; 95% confidence interval, 0.64-0.78). The correlation was higher for lesions of 20 mm or less in their longest diameter than for larger lesions. The intramodal size correlation was lower for tumors with an extensive intraductal component than for tumors without an extensive intraductal component. The sonographic versus pathologic correlation of tumor size was less accurate when several lesions were present. CONCLUSIONS Sonography is useful for presurgical assessment of tumor size in patients with breast cancer, especially for single lesions of 20 mm or less and without an extensive intraductal component.

Abstract
INTRODUCTION The prevalence of epilepsy in multiple sclerosis (MS) is low and the occurrence of an epileptic seizure as a first sign of this illness is even more infrequent. The relationship between both these illnesses is not clear; as epilepsy is a common condition, a coincidental association only could exist between the two diseases. OBJECTIVE To establish a nexus of causality between epilepsy an MS. Clinical case. We present one case of epileptic seizures as the first manifestation of MS. The patient was a woman of 25 years old. The only result of the clinical examination was a right homonymous inferior cuadrantanopsy. The patient presented a high Tibbling index, lesions of demyelination in the subcortical occipital region and semioval centrum in the MRI and a pathological electroencephalogram; also, the visual and auditory evoked potential latency were delayed. CONCLUSIONS We related he results of the neuroimaging, the clinical examination and the complementary tests of the patient. The appears to be a causal association between epilepsy and MS.

Abstract
Chrysanthemum chlorotic mottle viroid (CChMVd) is an RNA of 398-399 nt that can adopt hammerhead structures in both polarity strands. We have identified by Northern-blot hybridization a nonsymptomatic strain (CChMVd-NS) that protects against challenge inoculation with the symptomatic strain (CChMVd-S). Analysis of CChMVd-NS cDNA clones has revealed a size and sequence very similar to those of the CChMVd-S strain. Some of the mutations observed in CChMVd-NS molecular variants were previously identified in CChMVd-S RNA, but others were never found in this RNA. When bioassayed in chrysanthemum, cDNA clones containing the CChMVd-NS specific mutations were infectious but nonsymptomatic. Site-directed mutagenesis showed that one of the CChMVd-NS-specific mutations, a UUUC --> GAAA substitution, was sufficient to change the symptomatic phenotype into the nonsymptomatic one without altering the final accumulation level of the viroid RNA. The pathogenicity determinant-to our knowledge, a determinant of this class has not been described previously in hammerhead viroids-is located in a tetraloop of the computer-predicted branched conformation for CChMVd RNA. Analysis of the sequence heterogeneity found in CChMVd-S and -NS variants strongly supports the existence of such a conformation in vivo, showing that the rod-like or quasi-rod-like secondary structure is not a universal paradigm for viroids.

Abstract
Viroids, subviral pathogens of plants, are composed of a single-stranded circular RNA of 246-399 nucleotides. Within the 27 viroids sequenced, avocado sunblotch, peach latent mosaic and chrysanthemum chlorotic mottle viroids (ASBVd, PLMVd and CChMVd, respectively) can form hammerhead structures in both of their polarity strands. These ribozymes mediate self-cleavage of the oligomeric RNAs generated in the replication through a rolling circle mechanism, whose two other steps are catalyzed by an RNA polymerase and an RNA ligase. ASBVd, and presumably PLMVd and CChMVd, replicate and accumulate in the chloroplast, whereas typical viroids replicate and accumulate in the nucleus. PLMVd and CChMVd do not adopt a rod-like or quasi rod-like secondary structure as typical viroids do but have a highly branched conformation. A pathogenicity determinant has been mapped in a defined region of the CChMVd molecule.

Abstract
The coexistence of trisomy 12 and deletions of chromosome 13 (13q12-q32) has rarely been observed in chronic lymphocytic leukaemia (CLL). Fluorescence in situ hybridization (FISH) performed on 600 consecutive CLL patients revealed the association of trisomy 12 and 13q14 deletion, of at least one of the three markers analysed (RB1, D13S319 and D13S25), in 55 cases (9% of 600 and 46% of 120 trisomy 12 cases). Trisomy 12 and isolated RB1 deletion were seen in 14/120 cases, trisomy 12 and D13S319/D13S25 deletion with diploid RB1 in 19/118, and trisomy 12 and deletion encompassing the three 13q markers studied in 22/118 cases. The heterogenous distribution of trisomy 12 and 13q deletions within the neoplastic B cells suggests that they are secondary rather than primary events in CLL leukaemogenesis.
