Deadly nightshade (Atropa belladonna) intoxication: an analysis of 49 children

Deadly nightshade (Atropa belladonna) intoxication has been infrequently reported in both children and adults in the literature. In this article, the clinical and laboratory findings of 49 children with acute deadly nightshade intoxication are reviewed. Our purpose was to enlighten the findings of deadly nightshade intoxication in childhood. The most common observed symptoms and signs were meaningless speech, tachycardia, mydriasis, and flushing. None of the children required mechanical ventilation or died in our series. The patients were categorized into two groups, mild/moderate and severe intoxication. Children with and without encephalopathy were accepted as severe and mild/moderate intoxication, respectively. While 43 children were placed in the group of mild/moderate intoxication, six were in severe intoxication group. We found that meaningless speech, lethargy, and coma were more common, but tachycardia was less common in the severe intoxication group (children with encephalopathy) (P B-0.05). In the treatment, neostigmine was used in all children because of no available physostigmine in our country. In conclusion, our findings showed that the initial signs and symptoms of acute deadly nightshade intoxication might be severe in some children, but no permanent sequel and death were seen in children. We also showed that meaningless speech, lethargy, coma, and absence of tachycardia were ominous signs in deadly nightshade intoxication in childhood. Lastly, we suggest that neostigmine may be used in cases of deadly nightshade intoxication if physostigmine cannot be available.
Brain alpha erythroid spectrin: identification, compartmentalization, and beta spectrin associations.

Using isoform and subunit specific antibodies we have determined the presence, localization, and beta spectrin associations of alpha erythroid spectrin, alpha SpI sigma*, as well as alpha non-erythroid spectrin, alpha SpII sigma 1, in mouse brain. Peptide specific antibodies against unique sequences within the beta SpII sigma 1, non-erythroid beta spectrin isoform, and within beta SpI sigma 1, erythrocyte beta spectrin isoform were used to compare the immunolocalization of beta spectrin subunit isoforms with that of alpha spectrin subunit isoforms and to immunoprecipitate spectrin tetramers in order to identify the subunit components by immunoblot analysis. The specificity and sensitivity of antibodies for isoform specific alpha and beta subunits was determined by immunodot and immunoblot methods. Immunohistochemical analyses indicated that beta SpI sigma 2 is located in neuronal somata and dendrites in mouse cerebellum. beta SpII sigma 1 is located in the medullary layer, chiefly composed of axonal tracts. Parallel immunohistochemical analysis with antibodies for the alpha and beta spectrin isoforms revealed that antibodies specific for the alpha subunit of erythrocyte spectrin (alpha SpI sigma 1) localized antigen to the somata and dendrites of cerebellar granule cell neurons, a pattern similar to that for the localization of the erythroid beta subunit (beta SpI sigma 2). In contrast antibodies specific for the non-erythroid alpha subunit (alpha SpII sigma 1) localized antigen to axons in the cerebellum corresponding to the pattern for the non-erythroid beta subunit (beta SpII sigma 1). The distinct localization of antigens by antisera which recognize either the alpha subunit of red blood cell spectrin or the alpha subunit of non-erythroid brain spectrin, together with the correspondence of their localization with appropriate beta subunits, clearly indicate that brain contains at least two species of spectrin each with distinct alpha and beta subunits. Immunoprecipitation experiments of cerebellar extracts using beta spectrin peptide specific antibodies followed by immunoblotting analysis confirmed the association of an erythroid alpha subunit isoform with a beta erythroid subunit isoform, as well as the association of non-erythroid alpha and beta subunits. In addition the immunoblot analysis of the immunoprecipitated material suggested there are minor populations of various hybrid tetramers in brain consisting of mixed erythroid and non-erythroid subunits. In summary these data collectively demonstrate that in mouse brain there are at least two alpha spectrin subunits, one erythroid alpha SpI sigma* and one non-erythroid alpha SpII sigma 1; these associate with an erythroid beta SpI sigma 1, and a non-erythroid beta SpII sigma 1 in the cerebellum of mouse.

On the Origin and Rarity of Interspecific Nest Parasitism in Birds

Interspecific nest parasitism is surprisingly rare in birds given the potential advantages for the parasite of exploiting the parental care of other species. One possibility is that chicks will not thrive with the parental care and food of heterospecifics. I simulated parasitism in nonparasitic congeners by switching eggs between nests of three species of titmice (great tit Parus major, blue tit Parus caeruleus, and coal tit Parus ater). The experiment showed that compatibility of parental care was not a constraint preventing parasitism. I also used the model system to compare fitness consequences of inter- and intraspecific nest parasitism, addressing the problem of which form is ancestral. Fledging success (body mass, survival) was higher when an egg was added to the nest of a smaller species than to the nest of a conspecific and also higher when the parasitic chick hatched early rather than late relative to host chicks. This suggests that interspecific nest parasitism may not require a stage of intraspecific nest parasitism before evolving but may start from a larger species directly exploiting the parental care of a smaller species or a species with shorter incubation period directly exploiting a species with longer incubation period.
Clinical features of Japanese elderly patients with type 1 autoimmune hepatitis.

OBJECTIVE In Caucasian type 1 autoimmune hepatitis patients with a main susceptibility of human leukocyte antigen DR3 and DR4, elderly patients have a higher frequency of concurrent autoimmune disease and cirrhosis at presentation. However, in Japanese patients, the disease is dominantly associated with DR4, and their clinical features may be different from those of previous reports. In this study, we assessed the clinical features of Japanese elderly patients with type 1 autoimmune hepatitis. METHODS We investigated 160 consecutive patients with type 1 autoimmune hepatitis, consisting of 34 elderly patients (> or = 65 years) and 126 younger patients (< 65 years). RESULTS There were no differences in form of clinical onset, frequencies of concurrent autoimmune disease, positive proportions of anti-nuclear antibody and/or anti-smooth muscle antibody, and human leukocyte antigen DR status between the two groups. However, the elderly patients had lower serum levels of albumin (p=0.0049), and higher frequencies of cirrhosis (F4) and pre-cirrhosis (F3) (p=0.014) compared with the younger patients. In contrast, in elderly patients, the cumulative incidental rate of the normalization of serum alanine aminotransferase levels within 6 months after the introduction of initial treatment was higher in those treated with prednisolone > or = 20 mg/day than those treated only with ursodeoxycholic acid (p=0.001). CONCLUSION We speculate that more years may pass between the occurrence of the disease and the presentation in Japanese elderly patients than in younger patients, and we considered that, even in elderly patients, those with advanced fibrosis should be treated with prednisolone in order to prevent progress of the disease into liver failure.
Cancer incidence and mortality attributable to alcohol consumption

Alcohol consumption is a major cause of disease and death. In a previous study, we reported that in 2002, 3.6% of all cases of cancer and a similar proportion of cancer deaths were attributable to the consumption of alcohol. We aimed to update these figures to 2012 using global estimates of cancer cases and cancer deaths, data on the prevalence of drinkers from the World Health Organization (WHO) global survey on alcohol and health, and relative risks for alcohol‐related neoplasms from a recent meta‐analysis. Over the 10‐year period considered, the total number of alcohol‐attributable cancer cases increased to approximately 770,000 worldwide (5.5% of the total number of cancer cases)—540,000 men (7.2%) and 230,000 women (3.5%). Corresponding figures for cancer deaths attributable to alcohol consumption increased to approximately 480,000 (5.8% of the total number of cancer deaths) in both sexes combined—360,000 (7.8%) men and 120,000 (3.3%) women. These proportions were particularly high in the WHO Western Pacific region, the WHO European region and the WHO South‐East Asia region. A high burden of cancer mortality and morbidity is attributable to alcohol, and public health measures should be adopted in order to limit excessive alcohol consumption.
Estimation of Premorbid Intelligence in Schizophrenia

To determine whether the National Adult Reading Test (NART) would provide a valid estimate of premorbid intelligence in schizophrenia, two schizophrenic samples were recruited, one consisting of 35 patients resident in long-stay wards, the other of 29 patients normally resident in the community. Schizophrenic patients were individually matched for age, sex, and education with a healthy, normal subject. Both schizophrenic samples scored significantly lower on the Wechsler Adult Intelligence Scale (WAIS) than their respective control groups. NART-estimated IQ did not differ significantly between the community-resident schizophrenics and their controls, suggesting that the NART provides a valid means of estimating premorbid intelligence in such a population. NART-estimated IQ was significantly lower in the long-stay sample than in their controls. Although low NART scores in this latter sample could be a valid reflection of low premorbid IQ, the alternative explanation that NART performance was impaired by onset of the disease cannot be ruled out.
The Effect of Anti-Thyroid Peroxidase Antibodies on Pregnancy Outcomes in Euthyroid Women.

INTRODUCTION Thyroid autoimmunity can have an adverse impact on the outcome of the pregnancy. Although the adverse effects of antithyroid antibodies have been well studied in hypothyroid women, their effects in euthyroid women are not well evaluated. AIM The study was conducted to assess the overall prevalence of anti-Thyroid Peroxidase (anti-TPO) antibodies in pregnant women and the effect of anti-TPO positivity on the outcome of pregnancy in euthyroid women. MATERIALS AND METHODS One thousand Indian women, in their first trimester were screened for anti-TPO antibodies to know the prevalence. Of this, euthyroid women who were positive for the presence of anti-TPO antibody were selected and their obstetric history was recorded. These women were followed up and the incidences of maternal and foetal complications were recorded. The complications were compared with the past obstetric history and outcomes in parity and gestation matched controls (anti-TPO negative). RESULTS The prevalence of anti-TPO positivity was 11% (n=110). Out of the positives, those with elevated Thyroid Stimulating Hormone (TSH) were 6.5%. The prevalence of euthyroid women who were anti-TPO positive was 4% (n=40). Anti-TPO positive, euthyroid females had a higher prevalence of infertility, anaemia and preterm delivery as compared to the controls (p<0.0001). No differences were observed between the two groups in terms of history of abruption recurrent abortions, intrauterine growth restriction, postpartum haemorrhage, symptomatic hypothyroidism, hypertensive disorders of pregnancy and foetal complications. CONCLUSION Anti-TPO positivity is common in pregnant women. Anti-TPO positive euthyroid females had a higher prevalence of infertility, anaemia as well as preterm delivery. Our results indicate that anti-TPO screening in pregnancy, may aid in early identification of the women at risk.
Refractive error and ocular biometry in Jordanian adults

The aim of this study was to establish the prevalence of refractive errors in Jordanian adults of working age, and to study the ocular biometric correlates of refractive error in this population. Refractive error and ocular biometry were measured in 1093 Jordanian adult subjects aged 17–40 years to determine the prevalence of refractive error, and explore structural correlations of ametropia. Refractive error was measured using a Grand‐Seiko GR‐3100K closed‐view infrared autorefractor. Ocular component measurements were made using A‐scan ultrasonography and autokeratometry. The prevalence of myopia [spherical equivalent refraction (SER) less than −0.50 DS] and hyperopia (SER greater than +0.50 DS) was 53.71 and 5.67% respectively; 40.62% of the sample was emmetropic (refraction between +0.50 D and −0.50 D inclusive in both principal meridians). The distribution of SER was found to show marked leptokurtosis, exhibiting a peak between plano and 1 D of myopia. Corneal radius, anterior chamber depth, crystalline lens thickness, vitreous chamber depth and axial length (AL) parameters were normally distributed in the population studied. AL to corneal curvature ratio was not normally distributed, and showed marked leptokurtosis. Linear regression analysis showed that AL correlated most closely with spherical equivalent refractive error. This study has established a database of refractive error prevalence and ocular biometric correlates of ametropia in a Middle Eastern population of working age.
Characterization of circannual patterns of metabolic recovery from activity in Rana catesbeiana at 15°C

SUMMARY We characterized carbohydrate metabolism following activity in the American bullfrog, Rana catesbeiana, and compared whole body metabolic profiles between two seasons. Forty-eight adult male Rana catesbeiana were chronically cannulated and injected with [U-14C]l-lactic acid sodium salt in either summer (June) or winter (January) after acclimation for 2 weeks at 15°C with a 12 h:12 h L:D photoperiod. Following injection with [14C]lactate, frogs were either allowed to rest for 240 min (REST), hopped for 2 min on a treadmill and immediately sacrificed (PE), or hopped for 2 min on a treadmill and allowed to recover for 240 min (REC 4). Exercise caused a significant increase in blood lactate level from 2.7±0.1 mmol l–1 at rest to 17.0±2.1 mmol l–1 immediately following exercise. This increase persisted throughout the recovery period, with average blood lactate level only reduced to 13.7±1.1 mmol l–1 after 240 min of recovery, despite complete recovery of intramuscular lactate levels. Lactate levels were not significantly different between seasons in any treatment (REST, PE, REC4), in either gastrocnemius muscle or blood. The vast majority of [14C]lactate was recovered in the muscle, in both winter (86.3%) and summer (87.5%). Season had no effect on total amount of 14C label recovered. [14C]Lactate was measured in the forms of lactate, glucose and glycogen, in the liver and the muscle sampled. The most robust difference found in seasonal metabolism was that both the liver and the gastrocnemius contained significantly higher levels of intracellular free glucose under all treatments in winter. These data suggest that, overall, bullfrogs accumulate and slowly clear lactate in a manner quite similar to findings in fish, other amphibians and lizards. Additionally, our findings indicate that lactate metabolism is not highly influenced by season alone, but that intracellular glucose levels may be sensitive to annual patterns.
What characterizes women in Norway who wish to have a caesarean section?

Aims: The aim of this study was to describe the characteristics of pregnant women who wish to have a caesarean section. Methods: Data were collected as part of the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health. Pregnant women booked for antenatal care in Norway between 1999 and 2006 were invited to participate in the study. Data on women's interest in mode of delivery and a set of associated variables were gathered from a questionnaire completed by 55,859 women at 30 weeks of pregnancy. Results: A wish for caesarean section was expressed by 10% of the women, and 33% thought that the woman herself should be allowed to decide whether to have a caesarean section or not. A negative experience from a previous labour, a second birth, an age>35, a low level of education, being single, being unemployed, having an assisted conception, expecting more than one foetus, experiencing urinary and bowel incontinence before current pregnancy, experiencing pelvic pain, having a fear of childbirth and reporting negative intra-psychic phenomena were significantly associated with a wish for caesarean section. Conclusions: At 30 weeks of pregnancy, one out of 10 women in a sample of Norwegian women would choose a caesarean section. Negative experiences from previous pregnancies and fear of giving birth are two of the strongest factors associated with a wish for a caesarean section and should be taken into consideration.
MOLECULAR EVOLUTION OF GLUTAMINE SYNTHETASE II AND III IN THE CHROMALVEOLATES 1

Glutamine synthetase (GS) is encoded by three distinct gene families (GSI, GSII, and GSIII) that are broadly distributed among the three domains of life. Previous studies established that GSII and GSIII isoenzymes were expressed in diatoms; however, less is known about the distribution and evolution of the gene families in other chromalveolate lineages. Thus, GSII cDNA sequences were isolated from three cryptophytes (Guillardia theta D. R. A. Hill et Wetherbee, Cryptomonas phaseolus Skuja, and Pyrenomonas helgolandii Santore), and GSIII was sequenced from G. theta. Red algal GSII sequences were obtained from Bangia atropurpurea (Mertens ex Roth) C. Agardh; Compsopogon caeruleus (Balbis ex C. Agardh) Mont. ; Flintiella sanguinaria F. D. Ott and Porphyridium aerugineum Geitler; Rhodella violacea (Kornmann) Wehrmeyer and Dixoniella grisea (Geitler) J. L. Scott, S. T. Broadwater, B. D. Saunders, J. P. Thomas et P. W. Gabrielson; and Stylonema alsidii (Zanardini) K. M. Drew. In Bayesian inference and maximum‐likelihood (ML) phylogenetic analyses, chromalveolate GSII sequences formed a weakly supported clade that nested among sequences from glaucophytes, red algae, green algae, and plants. Red algal GSII sequences formed two distinct clades. The largest clade contained representatives from the Cyanidiophytina and Rhodophytina and grouped with plants and green algae. The smaller clade (C. caeruleus, Porphyra yezoensis, and S. alsidii) nested within the chromalveolates, although its placement was unresolved. Chromalveolate GSIII sequences formed a well‐supported clade in Bayesian and ML phylogenies, and mitochondrial transit peptides were identified in many of the sequences. There was strong support for a stramenopile‐haptophyte‐cryptophyte GSIII clade in which the cryptophyte sequence diverged from the deepest node. Overall, the evolutionary history of the GS gene families within the algae is complex with evidence for the presence of orthologous and paralogous sequences, ancient and recent gene duplications, gene losses and replacements, and the potential for both endosymbiotic and lateral gene transfers.
Initial experience of single-port video-assisted thoracoscopic surgery sleeve lobectomy and systematic mediastinal lymphadenectomy for non-small-cell lung cancer.

BACKGROUND In this study, we evaluate the feasibility and safety of single-port video-assisted thoracoscopic surgery (VATS) sleeve lobectomy (SL) and systematic mediastinal lymphadenectomy and summarize our surgical experience. METHODS From October 2014 to December 2015, eight cases of single-port VATS SL [seven male patients and one female patient, median age 56.0 (range, 38-63) years] were performed by a single group of surgeons in Fujian Medical University Fujian Union Hospital. The median tumor size was 2.7 cm. Types of resection included four right upper, one right lower, and three left upper sleeve lobectomies. Systematic mediastinal lymphadenectomy was performed in all patients. A modified anastomosis technique developed by the author (Chen's technique) was applied for bronchial anastomosis. Postoperative outcome and short-term follow-up data were recorded and analyzed. RESULTS All eight operations were completed uneventfully with no conversion to thoracotomy or reoperation required. No perioperative death was observed. Major results (medians or percentages) were as follows: operative duration, 234.5 [185-345] min; bronchial anastomosis duration, 38.0 [30-43] min; blood loss, 65.0 [50-200] mL; number of lymph node dissected, 22.5 [18-37]. The postoperative complication rate was 37.5% (three of eight cases, including two pulmonary infections and one atrial fibrillation). All patients recovered and were discharged uneventfully with symptomatic therapy. Pathology showed squamous cell carcinoma in seven patients and adenocarcinoma in one patient; two patients were in TNM stage IB, three in stage IIA, one in stage IIB, and two in stage IIIA. The mean follow-up was 7.5 [2-15] months. There were no tumor recurrences or bronchial anastomotic complications. CONCLUSIONS Single-port VATS SL and mediastinal lymphadenectomy are safe and feasible. Improvements in operating procedures can help facilitate single-port VATS. The application of Chen's technique in bronchial anastomosis is easy and reliable and shows a satisfactory short-term clinical outcome.
Evidence That Partial Unwrapping of DNA from Nucleosomes Facilitates the Binding of Heat Shock Factor following DNA Replication in Yeast*

In the yeast Saccharomyces cerevisiae, heat shock transcription factor (HSF) binds heat shock element (HSE) DNA shortly after DNA replication, independently of its activation by heat shock. To determine if HSF binding occurs before newly replicated DNA is packaged into nucleosomes, we inserted an HSE into a DNA segment that normally forms a positioned nucleosome in vivo. Transcription from constructs designed to create steric competition between binding of HSF and histone H2A-H2B dimers was generally poor, suggesting that nucleosome assembly precedes and inhibits HSF binding. However, one such construct was as transcriptionally active as a nucleosome-free control. Structural analyses suggested that ∼40 base pairs of DNA, including the HSE, had unwrapped from the 3′ edge of the histone octamer, allowing HSF to bind; ∼100 base pairs remained in association with the histone octamer, with the same translational and rotational orientation as was seen for the poorly transcribed constructs. Modeling studies suggest that the active and inactive constructs differ from one another in the ease with which the HSE and flanking sequences can adopt the curvature needed to form a stable nucleosome. These differences may influence the probability of DNA unwrapping from already assembled nucleosomes and the subsequent binding of HSF.
