How Native Prosody Affects Pitch Processing during Word Learning in Limburgian and Dutch Toddlers and Adults

In this study, Limburgian and Dutch 2.5- to 4-year-olds and adults took part in a word learning experiment. Following the procedure employed by Quam and Swingley (2010) and Singh et al. (2014), participants learned two novel word-object mappings. After training, word recognition was tested in correct pronunciation (CP) trials and mispronunciation (MP) trials featuring a pitch change. Since Limburgian is considered a restricted tone language, we expected that the pitch change would hinder word recognition in Limburgian, but not in non-tonal Dutch listeners. Contrary to our expectations, both Limburgian and Dutch children appeared to be sensitive to pitch changes in newly learned words, indicated by a significant decrease in target fixation in MP trials compared to CP trials. Limburgian and Dutch adults showed very strong naming effects in both trial types. The results are discussed against the background of the influence of the native prosodic system.
The health of urban Aboriginal people: insufficient data to close the gap

The Australian Government has committed to reducing Indigenous disadvantage, including closing the life‐expectancy gap within a generation, and to halving the gap in mortality rates for children under 5 years of age within a decade. Sixty per cent of the health gap between Indigenous and non‐Indigenous Australians is attributable to the health of Indigenous people living in non‐remote areas of Australia. We conducted a brief review of recent Australian original research publications on the health of the 53% of Indigenous people who live in urban areas, and found that data are sparse; there were only 63 studies in the past 5 years (11% of all articles about Indigenous health during this period). Although Indigenous Australians living in remote areas experience greater health disparity, the government will not achieve its aims without paying due attention to the non‐remote‐living population. More research is required, and particularly research that actually tests the impact of policies and programs.
Isolation and characterization of the estrogen receptor in human skin.

Evidence exists which suggests that skin is a target tissue for several steroid hormones. However, the receptors for certain steroids, e.g. estrogens, have not been demonstrated in human skin. Evidence is presented which identifies and characterizes an estrogen receptor in normal human skin. Fresh surgical specimens of normal face skin were stripped of excess sc tissue and used immediately. The skin was homogenized in 2 ml buffer/tissue with a Brinkmann Polytron homogenizer, and the homogenate was centrifuged for 10 min at 104 × g. This supernatant was again centrifuged for 1 h at 105 × g to obtain the cytosol. When this cytosol was incubated with [3H]estradiol, a specific binding protein for the steroid was detected. This binding protein displayed 1) a high affinity for estrogen (Kd ≃ 1.5 × 10-10 M), 2) steroid specificity, 3) tissue specificity, 4) a precipitation in a 40% saturated solution of ammonium sulfate, 5) a sedimentation value of 3S in sucrose gradients using high ionic conditions, and 6) two .
Current pharmacotherapeutic strategies for overactive bladder

Overactive bladder (OAB) is a chronic, distressing condition characterised by symptoms of urgency (sudden overwhelming urge to urinate) and frequency (urinating more than eight times daily), with or without urge urinary incontinence (sudden involuntary loss of urine). It affects millions of people of all ages and both sexes world wide, with greater prevalence in women and the elderly. The treatment of OAB is aimed at reducing debilitating symptoms, which have a significant effect on all aspects of an individual’s quality of life, including social, domestic, psychological, occupational, physical and sexual functioning. Anticholinergic agents are currently recommended as first-line therapy for OAB. Their use results in significant clinical improvement in patients, although a lack of selectivity for receptors in the bladder may lead to troublesome side effects, including dry mouth, blurred vision, somnolence, dizziness and constipation. Recent research efforts have focused on developing drugs with a reduced propensity for causing these problems. Of the available anticholinergic agents, oxybutynin and tolterodine are the most widely used to treat OAB. Studies directly comparing tolterodine immediate-release (IR) with oxybutynin IR have shown that the two agents have similar efficacy. However, tolterodine IR is significantly better tolerated, particularly with respect to the incidence and severity of dry mouth. An extended-release formulation of tolterodine (4 mg capsules) has recently been developed to allow for once-daily dosing. In addition to greater convenience, tolterodine extended-release has shown enhanced efficacy and tolerability compared with tolterodine IR.
The Performance of Synapses That Convey Discrete Graded Potentials in an Insect Visual Pathway

Synapses from nonspiking neurons transmit small graded changes in potential, but variability in their postsynaptic potential amplitudes has not been extensively studied. At synapses where the presynaptic signal is an all-or-none spike, the probabilistic manner of neurotransmitter release causes variation in the amplitudes of postsynaptic potentials. I have measured the reliability of the operation of synapses that convey small graded potentials between pairs of identified large, second-order neurons in the locust ocellar system. IPSPs are mediated by small rebound spikes, which are graded in amplitude, in the presynaptic neuron. A transfer curve plotting amplitudes of spikes against amplitudes of IPSPs has a characteristic S shape with a linear central portion where IPSP amplitude is between −0.2 and −0.6 as large as spike amplitude but shows appreciable scatter. Approximately half of the scatter is attributable to background noise, most of which originates in photoreceptors and persists in darkness. The remaining noise is intrinsic to the synapse itself and is usually 0.3–0.7 mV in amplitude. It limits the resolution with which two spike amplitudes can be distinguished from one another to ∼2 mV and, because the linear part of the transfer curve occupies ∼10 mV in spike amplitudes, limits the number of discrete signal levels that can be conveyed across the synapse to approximately five. The amplitude of the noise is constant throughout the synaptic operating range, which means it is unlikely that presynaptic membrane potential controls transmitter release by setting a single probability level for quantal release.
International School Children’s Health Needs

Rapid globalization and the integration of national economies have contributed to the sharp rise in enrollment in international schools. How does this global nomadism affect international school children and their individual health needs? This study attempts to find an answer by interviewing 10 school nurses, with varying degrees of experience in international schools in Sweden, Germany, and Switzerland. Through qualitative semistructured interviews, the school nurses described that the international school children expressed common health needs similar to the ones faced by children in other school settings. However, children in the international schools expressed additional context-specific health needs related to their transient lifestyle, such as language and cultural difficulties, emotional distress, vulnerability, homesickness, alienation, and increased physical health needs related to their expatriate lifestyle. These factors often present a challenge for the school nurse whose profession is to interpret the child’s health needs, which may be obscured by cultural diversity.
Mycobacteria lacking the RD1 region do not induce necrosis in the lungs of mice lacking interferon‐γ

The genetic region of difference 1 (RD1) in Mycobacterium tuberculosis has recently been hypothesized to encode for proteins that are cytotoxic to the host cell in nature. We demonstrate here that while M. tuberculosis grew progressively in the lungs of gene disrupted mice (GKO) unable to produce interferon‐γ (IFN‐γ), similar mice infected instead with M. bovis bacillus Calmette–Guérin (BCG) reproducibly exhibited an obvious slowing of the disease after about 20 days. Closer examination of BCG‐infected GKO mice showed a florid granulomatous inflammation in the lungs, whereas similar mice infected with M. tuberculosis exhibited wholesale progressive necrosis. In the BCG‐infected GKO mice large numbers of activated effector T cells, some strongly positive for the cytokine tumour necrosis factor, as well as activated natural killer cells accumulated in the lungs. To further test the hypothesis that the differences observed were directly associated with the loss of the RD1 region, it was then shown that a mutant of M. tuberculosis lacking RD1 grew progressively in both normal and GKO mice but failed to induce any degree of necrosis in either animal despite reaching similar levels in the lungs. However, when mice were infected with this mutant, in which the RD1 region had been restored by complementation, wholesale necrosis of the lungs again occurred. These data support the hypothesis that proteins encoded in the RD1 region are a major cause of necrosis and contribute significantly to the pathogenesis of the disease.
Association of LPP and TAGAP Polymorphisms with Celiac Disease Risk: A Meta-Analysis

Background: Lipoma preferred partner (LPP) and T-cell activation Rho GTPase activating protein (TAGAP) polymorphisms might influence the susceptibility to celiac disease. Therefore, we performed a meta-analysis by identifying relevant studies to estimate the risks of these polymorphisms on celiac disease. Methods: The PubMed, Web of Science and Embase databases were searched (up to October 2016) for LPP rs1464510 and TAGAP rs1738074 polymorphisms. Results: This meta-analysis included the same 7 studies for LPP rs1464510 and TAGAP rs1738074. The minor risk A allele at both rs1464510 and rs1738074 carried risks (odds ratios) of 1.26 (95% CI: 1.22–1.30) and 1.17 (95% CI: 1.14–1.21), respectively, which contributed to increased risks in all celiac disease patients by 10.72% and 6.59%, respectively. The estimated lambdas were 0.512 and 0.496, respectively, suggesting that a co-dominant model would be suitable for both gene effects. Conclusions: This meta-analysis provides robust estimates that polymorphisms in LPP and TAGAP genes are potential risk factors for celiac disease in European and American. Prospective studies and more genome-wide association studies (GWAS) are needed to confirm these findings, and some corresponding molecular biology experiments should be carried out to clarify the pathogenic mechanisms of celiac disease.
Epidemiology of injuries in First Division Spanish football

Abstract The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively collected from 16 teams (427 players) using a specific web-based survey during the 2008/2009 season. A total of 1293 injuries were identified (145 were recurring injuries). The overall injury incidence was 5.65 injuries per 1000 h of exposure. Injuries were much more common during competition than during training (43.53 vs. 3.55 injuries per 1000 h of exposure, P < 0.05). Most of the injuries (89.6%) involved the lower extremities, and overuse (65.7%) was the main cause. Muscle and tendon injuries were the most common types of injury (53.8%) among the players. The incidence of training injuries was greater during the pre-season and tended to decrease throughout the season, while the incidence of competition injuries increased throughout the season (all P < 0.05). In conclusion, the results of this study suggest the need for injury prevention protocols in the First Division of the Spanish Football League to reduce the number of overuse injuries in the muscles and tendons in the lower extremities. In addition, special attention should be paid during the pre-season and the competitive phase II (the last four months of the season) in order to prevent training and competition injuries, respectively.
Sphenopalatine and Anterior Ethmoidal Artery Ligation for Severe Epistaxis

Objectives: We describe the surgical treatment of severe epistaxis and evaluate the recurrence of bleeding in a nonrandomized retrospective trial. Methods: We performed a retrospective study comparing bilateral endoscopic ligation of the sphenopalatine artery alone (ELSPA) and bilateral endoscopic ligation of the sphenopalatine artery with concomitant bilateral external ligation of the anterior ethmoidal artery (ELSPEA) in the management of persistent epistaxis. Clinical and hematologic information, preoperative and surgical care, and short- and long-term outcomes were analyzed. The main outcome measure was recurrence of epistaxis in the short- and long-term follow-up periods. Results: Forty-five patients were enrolled in the study. There were 20 patients in group A (ELSPA) and 25 in group B (ELSPEA). Three patients in group A and no patients in group B had long-term (more than 2 weeks after surgery) re-bleeding. The difference between the two groups was not statistically significant (p > 0.05). Conclusions: We conclude that ELSPA and ELSPEA are effective, well-tolerated, reliable procedures if performed by an experienced surgeon. Their failure can be explained by anatomic lateral nasal wall variations and perioperative technical difficulties. They can be appropriate methods to treat severe recurrent epistaxis refractory to repeated nasal packing.
P2Y12 receptor inhibition and effect of morphine in patients undergoing primary PCI for ST-segment elevation myocardial infarction

Summary PRIVATE-ATLANTIC (P2Y12 Receptor Inhibition with VASP Testing using Elisa kit during the ATLANTIC study) is a pre-specified substudy of the randomised, double-blind ATLANTIC trial in patients with ST-segment elevation myocardial infarction, designed to help interpret the main trial results. The primary objective of ATLANTIC was to assess coronary reperfusion prior to percutaneous coronary intervention (PCI) with pre- vs in-hospital ticagrelor 180 mg loading dose (LD). PRIVATE-ATLANTIC assessed platelet inhibition in 37 patients by measurement of vasodilator-associated stimulated phosphoprotein (VASP) platelet reactivity index (PRI) and VerifyNow platelet reactivity units (PRU) before angiogram (T1), immediately after PCI (T2), 1 (T3), and 6 (T4) hours (h) after PCI, and before next study drug administration (T5). The median time difference between the two ticagrelor LD was 41 minutes. Platelet reactivity was unaffected at T1 when measured by VASP-PRI (89.8 vs 93.9% for pre- and in-hospital ticagrelor, respectively; p = 0.18) or PRU (239 vs 241; p = 0.82). Numerical differences were apparent at T2 and maximal at T3. Morphine administration significantly delayed onset of platelet inhibition at T3 (VASP-PRI 78.2 vs 23.4% without morphine; p = 0.0116) and T4 (33.1 vs 11.0%; p = 0.0057). In conclusion, platelet inhibition in ATLANTIC was unaffected by pre-hospital ticagrelor administration at the time of initial angiogram due to the short transfer delay. The maximum difference in platelet inhibition was detected 1 h after PCI (T3). Morphine administration was associated with delayed onset of action of ticagrelor and appeared more important than timing of ticagrelor administration.
The Effects of Efaproxyn™ (Efaproxiral) on Subcutaneous RIF-1 Tumor Oxygenation and Enhancement of Radiotherapy-Mediated Inhibition of Tumor Growth in Mice

Abstract Hou, H. , Khan, N. , Grinberg, O. Y. , Yu, H. , Grinberg, S. A. , Lu, S. , Demidenko, E. , Steffen, R. P. and Swartz, H. M. The Effects of Efaproxyn™ (Efaproxiral) on Subcutaneous RIF-1 Tumor Oxygenation and Enhancement of Radiotherapy-Mediated Inhibition of Tumor Growth in Mice. Radiat. Res. 168, 218–225 (2007). Efaproxiral, an allosteric modifier of hemoglobin, reduces hemoglobin-oxygen binding affinity, facilitating oxygen release from hemoglobin, which is likely to increase tissue pO2. The purpose of this study was to determine the effect of efaproxiral on tumor oxygenation and growth inhibition of RIF-1 tumors that received X radiation (4 Gy) plus oxygen breathing compared to radiation plus oxygen plus efaproxiral daily for 5 days. Two lithium phthalocyanine (LiPc) deposits were implanted in RIF-1 tumors in C3H mice for tumor pO2 measurements using EPR oximetry. Efaproxiral significantly increased tumor oxygenation by 8.4 to 43.4 mmHg within 5 days, with maximum increases at 22–31 min after treatment. Oxygen breathing alone did not affect tumor pO2. Radiation plus oxygen plus efaproxiral produced tumor growth inhibition throughout the treatment duration, and inhibition was significantly different from radiation plus oxygen from day 3 to day 5. The results of this study provide unambiguous quantitative information on the effectiveness of efaproxiral to consistently and reproducibly increase tumor oxygenation over the course of 5 days of treatment, modeling the clinical use of efaproxiral. Also, based on the tumor growth inhibition, the study shows the efaproxiral-enhanced tumor oxygenation was radiobiologically significant. This is the first study to demonstrate the ability of efaproxiral to increase tumor oxygenation and to increase the tumor growth inhibition of radiotherapy over 5 days of treatment.
Assessment of Bcl-2 Expression as Modulator of Fas Mediated Apoptosis in Acute Leukemia

Abstract Apoptosis is the primary mechanism through which most chemotherapeutic agents induce tumor cell death. The balance in the expression of pro (Fas/CD95) and anti-apoptotic protein (Bcl-2) may control the response of leukemic cells to chemotherapy and subsequently affect the patient's prognosis. The aim of this study was to determine the levels of Bcl-2 and Fas expression on blast cells from patients with acute leukemia and to correlate the degree of expression to the clinical and laboratory prognostic factors and the patient's outcome. Forty newly diagnosed patients with acute leukemia (16 ALL, 24 AML) were included in the study. Ten normal subjects of matched age and sex were studied as a reference control group. The degree of Bcl-2 and Fas expression on acute leukemia blast cells were assessed before the start of therapy and on mononuclear cells after 1 year of follow up, using flow cytometry. The degree of Bcl-2 and Fas expression were significantly higher in AML (P<0.01,<0.05, respectively) and ALL (P<0.01, <0.05, respectively) as compared to controls. The expression of Fas and Bcl-2 was related to FAB type with the highest Bcl-2 and lowest Fas expression in M5 and T-ALL (P<0.01, for all). In ALL, patients responding to induction chemotherapy revealed lower Bcl-2 and higher Fas expression when compared to non-responders (P<0.05). In contrast, in AML the difference between responders and non-responders to induction chemotherapy regarding Bcl-2 and Fas expressions was not statistically significant (P>0.05). Bcl-2 and Fas expression were significantly elevated in the relapsed acute leukemia group (in both AML and ALL) when compared to those in remission (P<0.01, <0.05, respectively). Bcl-2 and Fas expression at diagnosis was not significantly different when those surviving were compared to the group who had died, either in the ALL or AML groups (P>0.05). Bcl-2 expression was significantly correlated to bone marrow blast cell counts (R=0.6, P<0.01), blast cell distribution ratio (R=0.4, P<0.05) and lymphadenopathy (R=0.33, P<0.05). Whereas Fas expression was significantly correlated to bone marrow blast cell counts (R=0.52, P<0.01). In conclusion, assessment of Bcl-2 and Fas expression at diagnosis in acute leukemia (1) could predict responsiveness to induction chemotherapy in ALL but not in AML group but (2) could not predict patients out come both in ALL and AML groups.
An Analysis of Early Renal Transplant Protocol Biopsies – the High Incidence of Subclinical Tubulitis

To investigate the possibility that we have been underestimating the true incidence of acute rejection, we began to perform protocol biopsies after kidney transplantation. This analysis looks at the one‐week biopsies. Between March 1 and October 1, 1999, 100 adult patients undergoing cadaveric kidney or kidney/pancreas transplantation, or living donor kidney transplantation, underwent 277 biopsies. We focused on the subset of biopsies in patients without delayed graft function (DGF) and with stable or improving renal function, who underwent a biopsy 8.2 ± 2.6 d (range 3–18 d) after transplantation (n = 28). Six (21%) patients with no DGF and with stable or improving renal function had borderline histopathology, and 7 (25%) had acute tubulitis on the one‐week biopsy. Of the 277 kidney biopsies, there was one (0.4%) serious hemorrhagic complication, in a patient receiving low molecular weight heparin; she ultimately recovered and has normal renal function. Her biopsy showed Banff 1B tubulitis. In patients with stable or improving renal allograft function early after transplantation, subclinical tubulitis may be present in a substantial number of patients. This suggests that the true incidence of rejection may be higher than is clinically appreciated.
Adsorption of cyanophage AS-1 to unicellular cyanobacteria and isolation of receptor material from Anacystis nidulans

Cells of unicellular cyanobacteria of typological group Ia, containing approximately 50 mol% guanine + cytosine (G+C) in their DNA (R. Y. Stanier, R. Kunisawa, M. Mandel, and G. Cohen-Bazire, Bacteriol. Rev. 35:171-205, 1971), were susceptible to infection by the cyanophage AS-1. Cyanobacteria of the same typological group, containing approximately 65 mol% G+C in their DNA, did not adsorb the cyanophage AS-1 or adsorbed it at a low rate. AS-1 was not propagated by any of the investigated strains with a high G+C content in their DNA. However, cells of strains 6907 and 6911 were lysed by cyanophage AS-1. A comparison of the host range of this phage with the lipopolysaccharide composition of host and non-host cell walls suggests that lipopolysaccharides are involved in the adsorption process. About 8 microgram of lipopolysaccharide per ml from host strains inactivated 50% of the particles of a solution containing 100 PFU/ml after 60 min of incubation at 30 degrees C. Material with receptor activity was extracted from the host strain Anacystis nidulans KM. The extract was purified of glycolipids and pigments, and a fraction showing receptor activity was isolated. This fraction contained three polypeptides of molecular weights between 54,000 and 64,000. Heat and protease treatment of whole cells and of isolated receptor material decreased the receptor activity. The fluorescence intensity of A. nidulans cells labeled with 1-anilino-8-naphthalene sulfonate was increased when AS-1 was adsorbed to these cells. The participation of lipopolysaccharides and proteins in the formation of the receptor complex is discussed.
