Foreskin surgery under local anaesthetic – OK? Or oh no!

Aim: Foreskin surgical procedures such as circumcision, prepuceplasty, frenuloplasty, dorsal slit, reduction of paraphimosis etc. in the adult male is usually performed by both general surgeons and urologists. Our aim was to evaluate the acceptance of performing these procedures in the day procedure unit or in the emergency unit under penile block. 
Method: Fifty patients who underwent foreskin surgeries under local anaesthetic (LA) were evaluated with their experience. Twenty patients who underwent circumcision, 20 patients who underwent foreskin preserving operations such as frenuloplasty or prepuceplasty and 10 patients who underwent other procedures such as reduction of paraphimosis (five) and dorsal slit (five) were included inthe study. The patients were asked about their symptoms such as pain or discomfort during local infiltration of lignocaine, any discomfort during the actual procedure, post-operative discomfort and general acceptance. All the patients were given penile block using smaller size needle (25 gauge, 5/8th inch orange sterile luer slip hypodermic needle) and 1% plain lignocaine. Thirty doctors from general surgery (10), urology (10) and emergency medicine (10) participated in the survey. They were asked about their opinion, confidence and preference about performing foreskin surgical procedures under LA. This included both junior trainees, middle grade doctors and consultants. The majority of middle grade doctors and consultants were fairly confident in performing procedures under LA, whereas the junior trainees in surgery, urology and emergency were lacking confidence. 
Conclusion: Penile block is a safe and effective way ofproviding sufficient anaesthesia for foreskin surgeries. Thetechnique is easy to learn. It reduces post-operative pain aswell. It can reduce the risk and cost of administering generalanaesthesia. doctors who are in training surgical specialityand emergency medicine should be encouraged to learnthe principles and technique in administering penile block.

miR-433 overexpression attenuates the spindle assembly checkpoint response to paclitaxel

Paclitaxel is a microtubule inhibitory chemotherapeutic drug that is increasingly used for the treatment of solid tumours. In vitro studies have demonstrated that attenuating the spindle assemble checkpoint (SAC) alters the post-mitotic responses to paclitaxel. Furthermore, the aberrant expression of a number of the SAC proteins, MAD2, BUBR1, and Aurora A kinase, are associated with poor patient prognosis. We have identified a microRNA, miR-433, that regulates the expression of MAD2. Overexpression of miR-433 in Hela cells induced downregulation of MAD2 mRNA and protein expression. We have also shown that Hela cells overexpressing miR-433 and treated with paclitaxel are no longer capable of cyclin B stabilisation, and thus have lost the ability to activate the SAC in response to paclitaxel. In addition, cell viability assays showed that Hela cells overexpressing miR-433 and treated with paclitaxel have an attenuated response to paclitaxel compared with microRNA scrambled controls. We have characterised the levels of miR-433, MAD2 gene expression and MAD2 protein levels in a cohort of ovarian cancer cell lines. Cell viability assays on this cohort revealed that responsiveness to paclitaxel is associated with high MAD2 protein expression and lower miR-433 expression. We hypothesise that the expression of miR-433 when deregulated in cancer leads to altered MAD2 expression and a compromised SAC, a key feature underlying drug resistance to paclitaxel. In a pilot study of paired human breast tumour and normal breast tissue samples we have shown that expression levels of miR-433 are elevated in cancer tissue. Targeting this microRNA in cancer may improve the efficacy of paclitaxel in treating breast cancer and ovarian cancer.

Molecular study of cell degeneration and evolution induced by mRNA mistranslation

As proteínas existentes nas células são produzidas pelo mecanismo de tradução do mRNA, no qual a informação genética contida nos genes é descodificada em cadeias polipeptídicas. O código genético, que define as regras de descodificação do genoma, minimiza os erros de tradução do mRNA, garantindo a síntese de proteínas com elevada fidelidade. Esta é essencial para a estabilidade do proteoma e para a manutenção e funcionamento dos processos celulares. Em condições fisiológicas normais, os erros da tradução do mRNA ocorrem com frequências que variam de 10-3 a 10-5 erros por codão descodificado. Situações que aumentam este erro basal geralmente estão associadas ao envelhecimento, stresse e a doenças; no entanto, em certos organismos o código genético é traduzido naturalmente com elevado erro, indicando que a síntese de proteínas aberrantes pode de algum modo ser vantajosa. A fim de estudar a resposta celular aos erros de tradução do mRNA, construímos leveduras que incorporam serina no proteoma em resposta a um codão de leucina, usando a expressão constitutiva de um tRNASer mutante. Este fenómeno genético artificial provocou uma forte diminuição da esporulação, da viabilidade e da eficiência de mating, afectando imensamente a reprodução sexual da levedura. Observou-se também uma grande heterogeneidade no tamanho e na forma das células e elevada instabilidade genómica, com o aparecimento de populações poliplóides e aneuplóides. No sentido de clarificar as bases celulares e moleculares daqueles fenótipos e compreender melhor a biologia do erro de tradução do mRNA, construímos também células de levedura que inserem serina em resposta a um codão de leucina de modo indutível e controlado. Utilizaram-se perfis de mRNA total e de mRNA associado a polissomas para elucidar a resposta celular ao erro de tradução do mRNA. Observou-se a indução de genes envolvidos na resposta ao stresse geral, stresse oxidativo e na unfolded protein response (UPR). Um aumento significativo de espécies reactivas de oxigénio (ROS) e um forte impacto negativo na capacidade das células pós-mitóticas re-iniciarem o crescimento foram também observados. Este fenótipo de perda de viabilidade celular foi resgatado por scavangers de ROS, indicando que o stresse oxidativo é a principal causa de morte celular causada pelos erros de tradução. Este estudo levanta a hipótese de que o stresse oxidativo e a acumulação de ROS, ao invés do colapso súbito do proteoma, são as principais causas da degeneração celular e das doenças humanas associadas aos erros de tradução do genoma. ABSTRACT: Proteins are synthesized through the mechanism of translation, which uses the genetic code to transform the nucleic acids based information of the genome into the amino acids based information of the proteome. The genetic code evolved in such a manner that translational errors are kept to a minimum and even when they occur their impact is minimized by similar chemical properties of the amino acids. Protein synthesis fidelity is essential for proteome stability and for functional maintenance of cellular processes. Indeed, under normal physiological conditions, mistranslation occurs at frequencies that range from 10-3 to 10-5 errors per codon decoded. Situations where this basal error frequency increases are usually associated to aging and disease. However, there are some organisms where genetic code errors occur naturally at high level, suggesting that mRNA mistranslation can somehow be beneficial. In order to study the cellular response to mRNA mistranslation, we have engineered single codon mistranslation in yeast cells, using constitutive expression of mutant tRNASer genes. These mistranslating strains inserted serines at leucine-CUG sites on a proteome wide scale due to competition between the wild type tRNALeu with the mutant tRNASer. Such mistranslation event decreased yeast sporulation, viability and mating efficiencies sharply and affected sexual reproduction strongly. High heterogeneity in cell size and shape and high instability in the genome were also observed, with the appearance of some polyploid or aneuploid cell populations. To further study the cellular and molecular basis of those phenotypes and the biology of mRNA mistranslation, we have also engineered inducible mRNA misreading in yeast and used total mRNA and polysome associated mRNA profiling to determine whether codon misreading affects gene expression. Induced mistranslation up-regulated genes involved in the general stress response, oxidative stress and in the unfolded protein response (UPR). A significant increase in reactive oxygen species (ROS) and a strong negative impact on the capacity of post-mitotic cells to re-initiate growth in fresh media were also observed. This cell viability phenotype was rescued by scavengers of ROS, indicating that oxidative stress is the main cause of cell death caused by mRNA mistranslation. This study provides strong support for the hypothesis that oxidative stress and ROS accumulation, rather than sudden proteome collapse or major proteome disruption, are the main cause of the cellular degeneration observed in human diseases associated mRNA mistranslation.

Corroles : synthesis, functionalization and application as chemosensors

O trabalho de investigação apresentado nesta dissertação foi desenvolvido tendo como objectivo a síntese e funcionalização de meso-triarilcorróis para utilização como quimiossensores. Este trabalho encontra-se apresentado ao longo de cinco capítulos. No primeiro capítulo são apresentadas as características gerais, as metodologias de síntese e de funcionalização de macrociclos de tipo corrólico, e descrevemse algumas aplicações em que têm sido utilizados. São ainda abordadas algumas das propriedades e características dos quimiossensores e os mecanismos de deteção de diversos analítos. No segundo capítulo, após uma pequena introdução às reações de Wittig e de Diels-Alder, escolhidas para a funcionalização do macrociclo corrólico, descreve-se o estudo efectuado para a obtenção do complexo de gálio(III) do 3- vinil-5,10,15-tris(pentafluorofenil)corrol e o seu comportamento como dieno, em reações de Diels-Alder na presença dos dienófilos 1,4-benzoquinona e 1,4- naftoquinona. Desses estudos resultaram dois aductos cuja habilidade sensorial, bem como a dos seus precursores, foi estudada, em solução, na presença de aniões esféricos (F-, Br-, Cl-), lineares (CN-) e volumosos (CH3COO-, H2PO4 -). Dos macrociclos estudados verificou-se que o corrol base-livre 5,10,15-tris(pentafluorofenil)corrol apresenta uma elevada sensibilidade para o anião fluoreto (F-), e que a coordenação do núcleo corrólico com gálio(III) diminui a afinidade para este anião. Em geral, todos os compostos mostraram afinidade para o anião cianeto (CN-) mesmo quando em suportes poliméricos. O gel de poliacrilamida revelou-se muito promissor na determinação de CN- em amostras de água. No terceiro capítulo é avaliada a reatividade do complexo de gálio(III) do 3- vinil-5,10,15-tris(pentafluorofenil)corrol ainda como dieno mas agora na presença de um dienófilo linear, o acetilenodicarboxilato de dimetilo. Desse estudo resultaram dois novos derivados corrólicos. A habilidade sensorial dos mesmos perante os aniões fluoreto, cianeto, acetato, e fosfato foi avaliada por espectroscopia de absorção e emissão tendo um dos aductos mostrado ser colorimétrico para o anião cianeto. No quarto capítulo descreve-se a síntese e caracterização de dois conjugados do tipo corrol-cumarina, resultantes de reações de Hetero-Diels-Alder entre o 3-vinil-5,10,15-tris(pentafluorofenil)corrolatogálio(III)(piridina) e orto-quinonasmetídeos gerados in situ a partir de reacções de Knoevenagel entre cumarinas e paraformaldeído. Realizaram-se estudos de afinidade sensorial para aniões e catiões com estes macrociclos, bem como com conjugados porfirinacumarina análogos. A inserção de uma unidade cumarina conferiu uma excepcional solubilidade tendo os novos derivados apresentado solubilidade em etanol. No quinto e último capítulo desta dissertação é avaliada a capacidade sensorial do 5,10,15-tris(pentafluorofenil)corrol e da sua espécie monoaniónica, para os catiões metálicos Na+, Ca2+, Cu2+, Cd2+, Pb2+, Hg2+, Ag+, Al3+, Zn2+, Ni2+, Cr3+, Ga3+, Fe3+ em tolueno e acetonitrilo. Os macrociclos corrólicos mostraram ser selectivos e colorimétricos para o catião Hg2+. Neste trabalho descreve-se ainda a síntese do derivado -iminocorrol, que após funcionalização com o 3-isocianatopropiltrimetoxisilano originou um derivado do tipo alcoxisilano, que foi, posteriormente, ancorado a nanopartículas comerciais de sílica. As novas nanopartículas ancoradas com o alcoxisilano corrol foram estudadas na presença de Cu2+, Hg2+ e Ag+. Na presença do catião Ag+ assistiu-se a uma mudança de cor, de verde para amarelo.

Handling the transfer of power: a note on the 1964 origins of the Douglas‐Home rules

Opposition is rarely a good preparation for government. The only post‐war government to enter office confident, well‐acquainted with the Civil Service and with a fund of administrative experience to draw on was the Attlee administration formed in 1945. The longer a party spends in opposition the more these assets disappear. Labour, by the end of the long period of Conservative rule in 1951–64, was largely unfamiliar with the burdens of office. This formed the background to the formulation of the Douglas‐Home rules, whereby informal contact is permitted between the Civil Service and the Opposition in advance of a general election. Since 1964 this arrangement has gradually become more extensive (especially after Neil Kinnock complained that the period for contact was too brief during the run‐up to the 1992 election) and more formalised. In late 1993 John Major agreed that contacts could be made from early 1996 in advance of the next election, rather than only during the last six months of a parliament, as had by then become the convention.’ The object of this short paper is, however, to explain how these rules originated.

Argonauta Video Database: General simulated scenes. Scene 1 (Right camera)

General simulated scenes These scenes followed a pre-defined script (see the Thesis for details), with common movements corresponding to general experiments. People go to or stand still in front of "J9", and/or go to the side of Argonauta reactor and come back again. The first type of movement is common during Irradiation experiments, where a material sample is put within the "J9" channel; and also during neutrongraphy or gammagraphy experiments, where a sample is placed in front of "J9". Here, the detailed movements of putting samples on these places were not reproduced in details, but only the whole bodies' movements were simulated (as crouching or being still in front of "J9"). The second type of movement may occur when operators go to the side of Argonauta to verify some operational condition. - Scene 1 (Obs.: Scene 1 of the "General simulated scenes" class): Comprises one of the scenes with two persons.

On the applicability of mathematics : philosophical and historical perspectives

The present thesis is a contribution to the debate on the applicability of mathematics; it examines the interplay between mathematics and the world, using historical case studies. The first part of the thesis consists of four small case studies. In chapter 1, I criticize "ante rem structuralism", proposed by Stewart Shapiro, by showing that his so-called "finite cardinal structures" are in conflict with mathematical practice. In chapter 2, I discuss Leonhard Euler's solution to the Königsberg bridges problem. I propose interpreting Euler's solution both as an explanation within mathematics and as a scientific explanation. I put the insights from the historical case to work against recent philosophical accounts of the Königsberg case. In chapter 3, I analyze the predator-prey model, proposed by Lotka and Volterra. I extract some interesting philosophical lessons from Volterra's original account of the model, such as: Volterra's remarks on mathematical methodology; the relation between mathematics and idealization in the construction of the model; some relevant details in the derivation of the Third Law, and; notions of intervention that are motivated by one of Volterra's main mathematical tools, phase spaces. In chapter 4, I discuss scientific and mathematical attempts to explain the structure of the bee's honeycomb. In the first part, I discuss a candidate explanation, based on the mathematical Honeycomb Conjecture, presented in Lyon and Colyvan (2008). I argue that this explanation is not scientifically adequate. In the second part, I discuss other mathematical, physical and biological studies that could contribute to an explanation of the bee's honeycomb. The upshot is that most of the relevant mathematics is not yet sufficiently understood, and there is also an ongoing debate as to the biological details of the construction of the bee's honeycomb. The second part of the thesis is a bigger case study from physics: the genesis of GR. Chapter 5 is a short introduction to the history, physics and mathematics that is relevant to the genesis of general relativity (GR). Chapter 6 discusses the historical question as to what Marcel Grossmann contributed to the genesis of GR. I will examine the so-called "Entwurf" paper, an important joint publication by Einstein and Grossmann, containing the first tensorial formulation of GR. By comparing Grossmann's part with the mathematical theories he used, we can gain a better understanding of what is involved in the first steps of assimilating a mathematical theory to a physical question. In chapter 7, I introduce, and discuss, a recent account of the applicability of mathematics to the world, the Inferential Conception (IC), proposed by Bueno and Colyvan (2011). I give a short exposition of the IC, offer some critical remarks on the account, discuss potential philosophical objections, and I propose some extensions of the IC. In chapter 8, I put the Inferential Conception (IC) to work in the historical case study: the genesis of GR. I analyze three historical episodes, using the conceptual apparatus provided by the IC. In episode one, I investigate how the starting point of the application process, the "assumed structure", is chosen. Then I analyze two small application cycles that led to revisions of the initial assumed structure. In episode two, I examine how the application of "new" mathematics - the application of the Absolute Differential Calculus (ADC) to gravitational theory - meshes with the IC. In episode three, I take a closer look at two of Einstein's failed attempts to find a suitable differential operator for the field equations, and apply the conceptual tools provided by the IC so as to better understand why he erroneously rejected both the Ricci tensor and the November tensor in the Zurich Notebook.

Aggregating Brain Cell Cultures as a Model to Study Ischaemia-induced Neurodegeneration.

Rotation-mediated aggregating brain cell cultures at two different maturational stages (DIV 11 and DIV 20) were subjected for 1 or 2 hours to ischaemic conditions by transient immobilization (arrest of media circulation). During recovery, cell damage was evaluated by measuring changes in cell type-specific enzyme activities and total protein content. It was found that in immature cultures (DIV 11), immobilization for 1 or 2 hours did not affect the parameters measured. By contrast, at DIV 20, ischaemic conditions for 1 hour caused a pronounced decrease in the activities of glutamic acid decarboxylase and choline acetyltransferase. A significant decrease in these neuron-specific enzyme activities was found at post-ischaemic days 1-14, indicating immediate and irreversible neuronal damage. The activity of the astrocyte-specific enzyme, glutamine synthetase, was significantly increased at 4 days post-treatment; equal to control values at 6 days; and significantly decreased at 14 days after the ischaemic insult. Immobilization of DIV 20 cultures for 2 hours caused a drastic reduction in all the parameters measured at post-ischaemic day 6. Generally, the ischaemic conditions appeared to be more detrimental to neurons than to astrocytes, and GABAergic neurons were more affected than cholinergic neurons.

Teaching Principled negotiation skills to parents and their children : the impact of parental involvement /

This study explored the impact of training parents and children concurrently in principled negotiation skills for the purpose of developing negotiation skills and problem solving abilities in children. A second experimental group was utilized to determine the viability of negotiation skills training of junior elementary students for the purpose of improving problem solving and conflict resolving abilities. The student population in each experimental group was trained using The Program for Young Negotiators (Curhan, 1996). A control group was also established using the remaining grade four and five students attending the participating school. These students did not receive training as part of this study. Student group distribution was as follows: Experimental group 1 (students with parent participant) consisted of 10 (5 grade five and 5 grade 4 students), Experimental group 2 students without parent participant) consisted of 48 (20 grade 4 and 28 grade 5 students), and the Control group 3 (55 grade 4 and 5 students). The impact of training was measured using the Five Factor Negotiation Scale developed for use with the Program for Young Negotiators (Curhan, 1996). This measure was employed as a pre- and post-test questionnaire to the total student population, (113 students) to determine levels of ability in each of the key elements of negotiation, personal initiative, collaboration, communication, conflict based perspective taking, and conflict resolution approach (Nakkula & Nikitopoulos, unpublished). This measure has a coefficient alpha of .75 which is acceptable for this type of affective instrument. As well, open ended ability questions designed to measure ability, knowledge, and behaviour as they relate to negotiation skill application were given to the total student population, (113 students). Finally, journals were maintained by the students in both experimental groups, and informal feedback discussions were held with students and parents participating in the study.The intent of using both qualitative and quantitative measures was to provide an overall perspective of student abilities as they related to principled negotiation skills. While the quantitative measures were from the student perspective, more qualitative information was sought from parents and teachers through informal interviews, discussions, and use of confidential feedback cards. For analysis purposes, the ability questions were randomly selected for Experimental group 2 and Control group 3 in an effort to balance the groups more equitably with Experimental group 1. The findings of this study indicate that students of the junior elementary school age can be taught how to perceive conflict in a more constructive way. However, they are not as likely to use their skills when the conflict is with a sibling as they are with a peer, a teacher, or a parent. While no statistically significant differences between mean scores for Experimental groups 1 and 2 exist some subtle differences are noted. Overall, increases in mean scores for grade 4 students exceeded the increases for grade 5 students within Experimental group 1 . The implication being that younger students benefit more from having a parent trained in principled negoUation skills than older students. The skill level of a parent in principled negotiation can not be underesUmated. Without a consistent and effective role model the likelihood of developing student skill level to a point of automaticity is greatly reduced. Enough so that perhaps the emphasis should be placed on training parents more so than the students.

The Role of Pyruvate Dehydrogenase Kinase-4 in Post-Exercise Glycogen Recovery

The pyruvate dehydrogenase (PDH) complex regulates the oxidation of carbohydrates in mammals. Decreased activation of PDH following exhaustive exercise may aid the resynthesis of glycogen through increased activity of PDH kinase-4 (PDK4), one of four kinases that decrease the activity of the PDH complex. The purpose of this study was to examine the role of PDK4 in post-exercise glycogen resynthesis. Wild-type (WT) and PDK4-knockout (PDK4-KO mice) were exercised to exhaustion and were sampled at rest (Rest), at exercise exhaustion (Exh), and after two-hours post-exercise (Rec). Differences in feeding post-exercise led to the addition of a PDK4-KO group, pair-fed (PF) with WT mice. Glycogen fully recovered in all Rec groups in muscle however remained low in the PF group in liver. Flux through PDH was elevated in PDK4-KO muscle with feeding and low in the PF group in both tissues. This suggests PDK4 may fine-tune flux through PDH during exercise recovery.

Canadian Shredded Wheat Company Fonds

In 1893 Attorney Henry Drushel Perky and William H. Ford invented a machine for the preparation of cereals for food. Perky soon realized that the actual cereal biscuits were more popular than the machines and he opened Shredded Wheat plants in Massachusetts and Niagara Falls, New York. In 1904, the Niagara Falls, Canada plant was opened. These factories also served as tourist attractions. In 1907, one hundred thousand people visited the plants on both sides of the border. In 1928, the company was sold to The National Biscuit Company and the product name changed to Nabisco Shredded Wheat. The name of the plant was changed to Nabisco Foods in 1956 to reflect the variety of foods that were being produced at that time. In 1985, Nabisco was purchased by J.R. Reynolds thus forming RJR Nabisco. In 1994, RJR sold its breakfast cereal business to Kraft Foods and the international licenses to General Mills. Shredded Wheat is now integrated into the Post Foods portfolio. with information from: Niagara Falls Canada a History by The Kiwanis Club of Stamford, Ontario Inc. and Business Source Complete
