Heterogeneity and plasticity in the development of language: a 17-year follow-up of children referred early for possible autism.

BACKGROUND Delayed, abnormal language is a common feature of autism and language therapy often a significant component of recommended treatment. However, as with other disorders with a language component, we know surprisingly little about the language trajectories and how varied these might be across different children. Thus, we know little about how and when language problems might resolve, whether there are periods of relative stability or lack of change and what periods might offer more favourable circumstances for intervention. METHODS Expressive and receptive language was measured on six occasions between age 2 and 19 on a cohort of 192 children initially referred for autism. Latent class growth models were fitted to characterize the patterns of heterogeneous development. RESULTS Latent class growth analysis identified seven classes. Between age 6 and 19, all classes tracked in parallel. Between ages 2 and 6, development was more heterogeneous with considerable variation in relative progress. In all groups, receptive and expressive language developed very largely in tandem. CONCLUSIONS The results confirmed previous analysis of children with specific language impairment where progress beyond age 6 was remarkably uniform. Greater variation was evident before this age with some groups making clearly better or worse progress compared to others. While this developmental heterogeneity may simply be a reflection of variation in preexisting and unchanging biological disposition, it may also reflect, at least in part, greater sensitivity in the early years to environments that are more or less supportive of language development. These findings contribute to the case for the importance of early intervention.
Ranibizumab and bevacizumab for neovascular age-related macular degeneration.

BACKGROUND Clinical trials have established the efficacy of ranibizumab for the treatment of neovascular age-related macular degeneration (AMD). In addition, bevacizumab is used off-label to treat AMD, despite the absence of similar supporting data. METHODS In a multicenter, single-blind, noninferiority trial, we randomly assigned 1208 patients with neovascular AMD to receive intravitreal injections of ranibizumab or bevacizumab on either a monthly schedule or as needed with monthly evaluation. The primary outcome was the mean change in visual acuity at 1 year, with a noninferiority limit of 5 letters on the eye chart. RESULTS Bevacizumab administered monthly was equivalent to ranibizumab administered monthly, with 8.0 and 8.5 letters gained, respectively. Bevacizumab administered as needed was equivalent to ranibizumab as needed, with 5.9 and 6.8 letters gained, respectively. Ranibizumab as needed was equivalent to monthly ranibizumab, although the comparison between bevacizumab as needed and monthly bevacizumab was inconclusive. The mean decrease in central retinal thickness was greater in the ranibizumab-monthly group (196 μm) than in the other groups (152 to 168 μm, P=0.03 by analysis of variance). Rates of death, myocardial infarction, and stroke were similar for patients receiving either bevacizumab or ranibizumab (P>0.20). The proportion of patients with serious systemic adverse events (primarily hospitalizations) was higher with bevacizumab than with ranibizumab (24.1% vs. 19.0%; risk ratio, 1.29; 95% confidence interval, 1.01 to 1.66), with excess events broadly distributed in disease categories not identified in previous studies as areas of concern. CONCLUSIONS At 1 year, bevacizumab and ranibizumab had equivalent effects on visual acuity when administered according to the same schedule. Ranibizumab given as needed with monthly evaluation had effects on vision that were equivalent to those of ranibizumab administered monthly. Differences in rates of serious adverse events require further study. (Funded by the National Eye Institute; ClinicalTrials.gov number, NCT00593450.).
Relationship between the ankle-brachial index and the risk of coronary heart disease and stroke: the circulatory risk in communities study.

AIM Patients with peripheral artery disease (PAD) are at a high risk of cardiovascular disease (CVD) among Western populations. However, evidence for an elevated risk in Asian populations is limited. METHODS This prospective cohort study examined 939 Japanese men 60-74 years of age at the time of the baseline survey. A total of 115 cases of CVD were detected during a median 9.3 years of follow-up, and the ankle brachial blood pressure index (ABI) functioned as a surrogate measurement of PAD. RESULTS The age-adjusted risks of coronary heart disease, ischemic stroke and ischemic CVD (coronary heart disease and ischemic stroke) were higher among men in the lowest ABI tertile compared with that observed in the men in the highest tertile (<1.08 vs. >1.17). These associations did not change substantially after adjusting for cardiovascular risk factors. The respective multivariable hazard ratios (HRs, 95% CI) for the three conditions were as follows: 2.48 (1.08-5.71), p for trend=0.03; 1.95 (0.94-4.02), p for trend=0.04; and 2.16 (1.25-3.72), p for trend=0.004. These results did not vary based on a comparison of the three ABI categories: ≤0.90, 0.91-1.10 and >1.10. The multivariable HRs (95% CI) for an ABI ≤0.90 versus >1.10 were as follows: 2.04 (0.67-6.20), p for trend=0.14 for coronary heart disease; 3.39 (1.10-10.5), p for trend=0.006 for ischemic stroke; and 2.61 (1.19-5.76), p for trend=0.003 for ischemic CVD. There were no associations between the ABI and the risk of hemorrhagic stroke. CONCLUSIONS A low ABI is associated with the risk of coronary heart disease, ischemic stroke and ischemic CVD in elderly Japanese men.
Tailored therapy and long-term surveillance of malignant germ cell tumors in the female genital system: 10-year experience

Objective To explore the appropriate treatment of malignant germ cell tumor (MGCT) in the female genital system, and to analyze the factors influencing both therapeutic response and survival outcome. Methods A cohort of 230-Chinese women diagnosed with MGCT of the genital system was retrospectively reviewed and prospectively followed. The demographic and pathological features, extent of disease and surgery, treatment efficiency, recurrence and survival were analyzed. Results MGCTs from different genital origins shared a similar therapeutic strategy and response, except that all eight vaginal cases were infantile yolk sac tumors. The patients’ cure rate following the initial treatment, 5-year overall survival and disease-free survival (DFS) were 85.02%, 95.00%, and 86.00%, respectively. Although more extensive excision could enhance the remission rate; it did not improve the patients’ survival. Instead, the level of the medical institution, extent of surgery and disease were independent prognostic factors for relapse (p<0.05). Approximately 20% of patients had recurrent or refractory disease, more than half of whom were in remission following secondary cytoreductive surgery with salvage chemotherapy. Conclusion Fertility-sparing surgery with or without standardized PEB/PVB (cisplatin, etoposide/vincristine, and bleomycin) chemotherapy is applicable for female MGCTs of different origins. Comprehensive staging is not required; nor is excessive debulking suggested. Appropriate cytoreduction by surgery and antineoplastic medicine at an experienced medical institution can bring about an excellent prognosis for these patients.
[Comparison of friction and abrasion between six different dental materials and natural enamel].

PURPOSE The purpose of this study was to evaluate and compare the friction and abrasion of six kinds of dental materials that was widely used clinically. The mechanisms were investigated to provide experimental reference for selecting proper restorative material to protect opposite natural enamel of the patients. METHODS In the experimental groups,pure Ti, Ti alloy, Au-Pd alloy, Ni-Cr alloy, AgHg alloy,ceramic were fabricated into thirty uniform 8.0mmx8. 0mmx2.0mm block. Five specimens in each group.In the control group,five recently extracted mandibular third molar of adults were fabricated into 8.0mmx8. 0mmx2.0mm block. Steatites were fabricated into discs in the diameter of 25mm and thickness of 2.0mm to act as counter sample materials. The mass loss of each specimen and the opposing steatite were weighted by electric balance. The volume loss of the materials and opposing steatites were analyzed by SPSS11.5 software package and the difference was compared between each group. RESULTS The ranking of the volume loss of six materials and enamel from the most to the least was group A, group E, group C, group D, group B, group F and group G. Significant difference was found between group A and the other groups. No significance was found between group G and F. The coefficient of friction of group A-G was 0.68, 0.12, 0.11, 0.41, 0.38, 0.48 and 0.65,respectively. CONCLUSION The six materials in this study were less resistant to wear than natural tooth. The wear of pure Ti, AgHg alloy and Ni-Cr alloy are to enamel.
Arts on referral interventions: a mixed-methods study investigating factors associated with differential changes in mental well-being.

BACKGROUND Art interventions may provide a cost-effective approach to improving mental well-being. Most evaluations concentrate on intervention characteristics and little is known about other factors which might contribute to successful outcomes. METHODS This pre-and-post intervention mixed-methods study explored influences on differential changes in measured well-being among participants of an Arts on Referral (AoR) scheme in the UK. Measured well-being scores of 44 volunteers and findings from six semi-structured interviews were triangulated. RESULTS Mean well-being scores improved by 8.0 (95% CI 4.8-11.3, P < 0.0001); the number of sessions attended and baseline scores were positively associated with outcome score. Participants from Black and Minority Ethnic (BME) groups and females appeared to show greater improvement in well-being scores than White British or male participants. Qualitative interviews supported and further explained these findings and suggested differential impacts of AoR may, in part, be explained by the importance of sharing experiences, reduced social isolation and external stressors. CONCLUSION This study supports the use of AoR interventions for improving well-being among those facing short- and long-term mental health challenges. However, given the reduced sample size and the pre-post design results should be interpreted with caution and potential differences between ethnic groups and genders should be further explored.
The Efficacy of Several Neuromuscular Monitoring Modes at the P6 Acupuncture Point in Preventing Postoperative Nausea and Vomiting

BACKGROUND:In this study, we tested the efficacy of several neuromuscular monitoring modes at the P6 acupuncture point for preventing postoperative nausea and vomiting (PONV). METHODS:In this prospective, double-blind, randomized, placebo-controlled trial, 264 women undergoing laparoscopic hysterectomy were evaluated for PONV. Neuromuscular blockade was monitored by acceleromyography with 1-Hz single twitch (ST) over the ulnar nerve (n = 54, control), and ST (n = 52), train-of-four (n = 53), double-burst stimulation (n = 53), or tetanus (n = 52) over the median nerve stimulating at the P6 acupuncture point. RESULTS:The incidence of PONV (P = 0.022), the number of requests for patient-controlled analgesia (P = 0.009), and total patient-controlled analgesia volume (P = 0.042) 6 hours after tetanic stimulation were significantly reduced in the treatment group compared with the control group. Overall, patients in the tetanus group were more satisfied with the management of PONV compared with patients in the control group. CONCLUSION:Tetanic stimulation applied to the P6 acupuncture point can reduce PONV after laparoscopic hysterectomy compared with ST stimulation of the ulnar nerve, resulting in a greater degree of patient satisfaction. None of the stimulations, ST, train-of-four, or double-burst, applied to the P6 acupuncture point significantly affected PONV.
Parrot Bornavirus (PaBV)-2 isolate causes different disease patterns in cockatiels than PaBV-4

ABSTRACT Psittaciform 1 bornavirus (PaBV) has already been shown to be the aetiologic agent of proventricular dilatation disease, a significant disease of birds. However, the pathogenesis of PaBV infection has not yet been resolved and valid data regarding the pathogenicity of different PaBV species are lacking. Thus, the present study was aimed to characterize the influence of two different PaBV species on the course of disease. Eighteen cockatiels were inoculated intracerebrally (i.c.) or intravenously (i.v.) with a PaBV-2 isolate under the same conditions as in a previous study using PaBV-4. Birds were surveyed and sampled for 33 weeks to analyse the course of infection and disease in comparison to that of PaBV-4. Similar to PaBV-4, PaBV-2 induced a persistent infection with seroconversion (from day 6 p.i. onwards) and shedding of viral RNA (from day 27 p.i. onwards). However, in contrast to PaBV-4, more birds displayed clinical signs and disease progression was more severe. After PaBV-2 infection, 12 birds exhibited clinical signs and 10 birds revealed a dilated proventriculus in necropsy. After PaBV-4 infection only four birds revealed clinical signs and seven birds showed a dilatation of the proventriculus. Clinically, different courses of disease were observed after PaBV-2 infection, mainly affecting the gastrointestinal tract. This had not been detected after PaBV-4 infection where more neurological signs were noted. The results provide evidence for different disease patterns according to different PaBV species, allowing the comparison between the infection with two PaBV species, and thus underlining the role of viral and individual host factors for disease outcome.
Time course of change in calcium x phosphorus product after percutaneous ethanol injection therapy.

BACKGROUND Percutaneous ethanol injection therapy (PEIT) effectively suppresses PTH secretion, but the change in the serum calcium and phosphorus product (Ca x P) after PEIT has not been fully evaluated. METHODS Twenty-seven haemodialysis patients with severe secondary hyperparathyroidism (2HPT) were divided into two groups according to their intact PTH (i-PTH) concentrations 6 months after PEIT: (i). effective (E) group, i-PTH concentration <360 pg/ml; and (ii). non-effective (N) group i-PTH > or = 360 pg/ml. The changes in serum calcium and phosphorus concentrations and the Ca x P were recorded for the following 2 years under post-PEIT medical treatment with oral calcitriol or intravenous 22-oxacalcitriol (OCT). RESULT In the E group, the i-PTH concentrations decreased to <300 pg/ml 1 year after PEIT (801+/-302 to 280+/-134 pg/ml), then increased to 435+/-201 pg/ml at 2 years. Serum calcium concentration did not show any significant change except for a transient reduction at 1 month after PEIT. The Ca x P decreased for 1 year (from 66.3+/-15.3 to 56.2+/-10.3 mg(2)/dl(2); P<0.05), in agreement with the course of phosphorus concentration, and continued to be <60 mg(2)/dl(2) up to 2 years after PEIT. The Ca x P tended to decrease more with OCT than oral calcitriol. In the N group, calcium and Ca x P increased significantly at 6 months after PEIT and remained at a high value. CONCLUSION Treatment with PEIT suppresses serum PTH concentration as well as Ca x P in the long term.
Effect of Ku proteins on IRES‐mediated translation

Background information. Ku is an abundant nuclear heterodimeric protein composed of 70 and 86 kDa subunits. As an activator of the catalytic subunit of DNA‐PK (DNA‐dependent protein kinase), Ku plays an important role in DNA repair and recombination. Ku is also involved in actions independent of DNA‐PK, such as transcription regulation and telomere maintenance. Although Ku is localized in the cytoplasm under specific cellular conditions, no functions for Ku outside of the nucleus have as yet been reported. In addition to DNA binding, Ku binds specific RNA sequences with high affinity. However, no specific cellular mRNA targets for Ku have been identified.
Cytosolic monoterpene biosynthesis is supported by plastid-generated geranyl diphosphate substrate in transgenic tomato fruits.

Geranyl diphosphate (GPP), the precursor of most monoterpenes, is synthesized in plastids from dimethylallyl diphosphate and isopentenyl diphosphate by GPP synthases (GPPSs). In heterodimeric GPPSs, a non-catalytic small subunit (GPPS-SSU) interacts with a catalytic large subunit, such as geranylgeranyl diphosphate synthase, and determines its product specificity. Here, snapdragon (Antirrhinum majus) GPPS-SSU was over-expressed in tomato fruits under the control of the fruit ripening-specific polygalacturonase promoter to divert the metabolic flux from carotenoid formation towards GPP and monoterpene biosynthesis. Transgenic tomato fruits produced monoterpenes, including geraniol, geranial, neral, citronellol and citronellal, while exhibiting reduced carotenoid content. Co-expression of the Ocimum basilicum geraniol synthase (GES) gene with snapdragon GPPS-SSU led to a more than threefold increase in monoterpene formation in tomato fruits relative to the parental GES line, indicating that the produced GPP can be used by plastidic monoterpene synthases. Co-expression of snapdragon GPPS-SSU with the O. basilicum α-zingiberene synthase (ZIS) gene encoding a cytosolic terpene synthase that has been shown to possess both sesqui- and monoterpene synthase activities resulted in increased levels of ZIS-derived monoterpene products compared to fruits expressing ZIS alone. These results suggest that re-direction of the metabolic flux towards GPP in plastids also increases the cytosolic pool of GPP available for monoterpene synthesis in this compartment via GPP export from plastids.
Intracavernous delivery of clonal mesenchymal stem cells restores erectile function in a mouse model of cavernous nerve injury.

INTRODUCTION Recently, much attention has focused on stem cell therapy; bone marrow-derived stem cells (BMSCs) are one of the most studied mesenchymal stem cells used in the field of erectile dysfunction (ED). However, a major limitation for the clinical application of stem cell therapy is the heterogeneous nature of the isolated cells, which may cause different treatment outcomes. AIM We investigated the effectiveness of mouse clonal BMSCs obtained from a single colony by using subfractionation culturing method (SCM) for erectile function in a mouse model of cavernous nerve injury (CNI). METHODS Twelve-week-old C57BL/6J mice were divided into four groups: sham operation group, bilateral CNI group receiving a single intracavernous (IC) injection of phosphate-buffered saline (20 μL) or clonal BMSCs (3 × 10(5) cells/20 μL), and receiving a single intraperitoneal (IP) injection of clonal BMSCs (3 × 10(5) cells/20 μL). MAIN OUTCOME MEASURES The clonal BMSC line was analyzed for cell-surface epitopes by using fluorescence-activated cell sorting and for differentiation potential. Two weeks after CNI and treatment, erectile function was measured by electrically stimulating the cavernous nerve. The penis was harvested for histologic examinations and Western blot analysis. RESULTS Clonal BMSCs expressed cell surface markers for mesenchymal stem cells and were capable of differentiating into several lineages, including adipogenic, osteogenic, and chondrogenic cells. Both IC and IP injections of clonal BMSCs significantly restored cavernous endothelial and smooth muscle content, and penile nNOS and neurofilament content in CNI mice. IC injection of clonal BMSCs induced significant recovery of erectile function, which reached 90-100% of the sham control values, whereas IP injection of clonal BMSCs partially restored erectile function. CONCLUSION We established a homogeneous population of mouse clonal BMSCs using SCM; clonal BMSCs successfully restored erectile function in CNI mice. The homogeneous nature of clonal mesenchymal stem cells may allow their clinical applications.
Supernormal excitability of human sensory fibers after ischemia

Weak electrical stimuli were applied to sensory fibers of the median nerve at the wrist, and the ascending action potentials were recorded at the elbow. This was done with or without a preceding conditioning stimulus to test for supernormal excitability to the second stimulus. In the resting nerve, supernormal excitability was present from 3 to 20 msec after a conditioning shock. After a period of ischemia, excitability was both exaggerated and prolonged. this observation confirms the presence in sensory fibers of a phenomenon previously described in motor fibers.
Female genital mutilation in children presenting to a London safeguarding clinic: a case series

Objective To describe the presentation and management of children referred with suspected female genital mutilation (FGM) to a UK safeguarding clinic. Design and setting Case series of all children under 18 years of age referred with suspected FGM between June 2006 and May 2014. Main outcome measures These include indication for referral, demographic data, circumstances of FGM, medical symptoms, type of FGM, investigations and short-term outcome. Results Of the 47 girls referred, 27 (57%) had confirmed FGM. According to the WHO classification of genital findings, FGM type 1 was found in 2 girls, type 2 in 8 girls and type 4 in 11 girls. No type 3 FGM was seen. The circumstances of FGM were known in 17 cases, of which 12 (71%) were performed by a health professional or in a medical setting (medicalisation). Ten cases were potentially illegal, yet despite police involvement there have been no prosecutions. Conclusions This study is an important snapshot of FGM within the UK paediatric population. The most frequent genital finding was type 4 FGM with no tissue damage or minimal scarring. FGM was performed at a young age, with 15% reported under the age of 1 year. The study also demonstrated significant medicalisation of FGM, which matches recent trends in international data. Type 4 FGM performed in infancy is easily missed on examination and so vigilance in assessing children with suspected FGM is essential.
Disentangling the role of heat and smoke as germination cues in Mediterranean Basin flora.

BACKGROUND AND AIMS The role of fire as a germination cue for Mediterranean Basin (MB) plants is still unclear. The current idea is that heat stimulates germination mainly in Cistaceae and Fabaceae and that smoke has a limited role as a post-fire germination cue, in comparison with other Mediterranean-type ecosystems (MTEs), suggesting that fire-stimulated germination is less relevant in the MB than in other MTEs. However, recent studies showed that the assembly of Mediterranean plant communities is strongly driven by post-fire germination, suggesting an important role for fire as a germination cue. We hypothesize that both heat and smoke have important effects on the different post-fire recruitment processes of MB species (e.g. level and rate of germination and initial seedling growth). METHODS To ascertain the role of heat and smoke in the post-fire germination response of MB woody plants, a germination experiment was performed with seven heat and two smoke treatments on 30 MB woody species from seven different families, including species with water-permeable seeds and species with water-impermeable seeds. KEY RESULTS Heat stimulated the germination (probability and rate) of 21 species and smoke in eight species, out of the 30 species studied. In addition, six species showed enhanced initial seedling growth after the smoke treatments. CONCLUSIONS The results suggest that both heat and smoke are important germination cues in a wide range of MB woody species and that fire-cued germination in woody plants of the MB may be as important as in other MTEs.
