Background Up to one-third of people affected by cancer experience ongoing psychological distress and would benefit from screening followed by an appropriate level of psychological intervention. This rarely occurs in routine clinical practice due to barriers such as lack of time and experience. This study investigated the feasibility of community-based telephone helpline operators screening callers affected by cancer for their level of distress using a brief screening tool (Distress Thermometer), and triaging to the appropriate level of care using a tiered model. Methods Consecutive cancer patients and carers who contacted the helpline from September-December 2006 (n = 341) were invited to participate. Routine screening and triage was conducted by helpline operators at this time. Additional socio-demographic and psychosocial adjustment data were collected by telephone interview by research staff following the initial call. Results The Distress Thermometer had good overall accuracy in detecting general psychosocial morbidity (Hospital Anxiety and Depression Scale cut-off score ≥ 15) for cancer patients (AUC = 0.73) and carers (AUC = 0.70). We found 73% of participants met the Distress Thermometer cut-off for distress caseness according to the Hospital Anxiety and Depression Scale (a score ≥ 4), and optimal sensitivity (83%, 77%) and specificity (51%, 48%) were obtained with cut-offs of ≥ 4 and ≥ 6 in the patient and carer groups respectively. Distress was significantly associated with the Hospital Anxiety and Depression Scale scores (total, as well as anxiety and depression subscales) and level of care in cancer patients, as well as with the Hospital Anxiety and Depression Scale anxiety subscale for carers. There was a trend for more highly distressed callers to be triaged to more intensive care, with patients with distress scores ≥ 4 more likely to receive extended or specialist care. Conclusions Our data suggest that it was feasible for community-based cancer helpline operators to screen callers for distress using a brief screening tool, the Distress Thermometer, and to triage callers to an appropriate level of care using a tiered model. The Distress Thermometer is a rapid and non-invasive alternative to longer psychometric instruments, and may provide part of the solution in ensuring distressed patients and carers affected by cancer are identified and supported appropriately.

SHMT (serine hydoxymethyltransferase), a type I pyridoxal 5'-phosphate-dependent enzyme, catalyses the conversion of L-serine and THF (tetrahydrofolate) into glycine and 5,10-methylene THE SHMT also catalyses several THF-independent side reactions such as cleavage of P-hydroxy amino acids, trans-amination, racemization and decarboxylation. In the present study, the residues Asn(341), Tyr(60) and Phe(351), which are likely to influence THF binding, were mutated to alanine, alanine and glycine respectively, to elucidate the role of these residues in THF-dependent and -independent reactions catalysed by SHMT. The N341A and Y60A bsSHMT (Bacillus stearothermophilus SHMT) mutants were inactive for the THF-dependent activity, while the mutations had no effect on THF-independent activity. However, mutation of Phe(351) to glycine did not have any effect oil either of the activities. The crystal structures of the glycine binary complexes of the mutants showed that N341A bsSHMT forms an external aldimine as in bsSHMT, whereas Y60A and F351G bsSHMTs exist as a Mixture of internal/external aldimine and gem-diamine forms. Crystal structures of all of the three Mutants obtained in the presence of L-allo-threonine were similar to the respective glycine binary complexes. The structure of the ternary complex of F351G bsSHMT with glycine and FTHF (5-formyl THF) showed that the monoglutamate side chain of FTHF is ordered in both the subunits of the asymmetric unit, unlike in the wild-type bsSHMT. The present studies demonstrate that the residues Asn(341) and Tyr(60) are pivotal for the binding of THF/FTHF, whereas Phe(351) is responsible for the asymmetric binding of FTHF in the two subunits of the dimer.

In 2015 the QLRC is conducting an inquiry into whether to extend legislative mandatory reporting duties for physical abuse and sexual abuse to early childhood education and care practitioners. The current legislation does not require these practitioners to report suspected cases of significant harm from physical or sexual absue to child welfare agencies. Based on the literature, and a multidisciplinary analysis, our overall recommendation is that we endorse the extension to selected early childhood education and care practitioners of Queensland’s current mandatory reporting duty in the Child Protection Act 1999 s 13E.

En el Centro Experimental Agropecuario La Calera, Managua, Nicaragua, se estableció en siembra de agosto a noviembre de 1976, un ensayo para determinar el tratamiento mas efectivo y rentable en el control de las malezas del cultivo de la soya (Glycine max L. Merril). Se escogió la variedad (Biloxi x Hardee) 69-341 de crecimiento determinado y ciclo vegetativo intermedio de 90-100 días. Los tratamientos que se evaluaron fueron los siguientes: Alachlor, Metribuzin, Linuron, Trifluralina, Alachlor + Metribuzin, Alachlor + Linuron, Alachlor + Trifluralina, Metribuzin + Lanuron, Metribuzin + Trifluralina, Linuron + Trifluralina en dosis de 2049,5 ml, 497,70 g, 966,00 g, 533,75 ml, 1024,75 ml + 248,85 g, 1024,75 ml + 483,00 g, 1024,75 ml + 266,87 ml, 248,85 g + 483,00 g, 248,85 g + 266,87 ml y 483,00 g, + 266,87 ml, por hectárea respectivamente, usando como comparadores un tratamiento mecánico y un testigo absoluto. Los tratamientos fueron distribuidos en un diseño de bloques completos al azar, con cuatro repeticiones. La parcela experimental consto de ocho surcos de cinco metros de largo, espaciados a cincuenta centímetros entre si y a 2,50 centímetros entre planta, correspondiendo a la parcela útil los cuatro surcos centrales a los cuales se les elimino 50,0 centímetros en cada extremo. El análisis de varianza practicado en los rendimientos de granos y en los porcentajes de control de malezas determino diferencia altamente significativa entre tratamientos al nivel de 0,01 de probabilidad de error. La mezcla de Alachlor + Metribuzin fue el tratamiento herbicida que ejerció el mayor control sobre gramíneas y hojas ancha, con 97,00 por ciento de control hasta los 60 días de emergida la soya. Los tratamientos Metribuzin, Metribuzin + Trifluralina y Alachlor fueron estadisticamente igual al nivel del 0,05 de probabilidad de error con: 74,00; 72,00 y 71;00 por ciento. Los tratamientos que menor porcentaje de control de malezas ejercieron hasta los 60 dias fueron Linuron y Linuron + Trifluralina con 34.00 por ciento. Los mayores rendimientos significativos de grano de soya, se lograron con: testigo mecanico, Alachlor + Metribuzin, Alachlor, y Alachlor + Linuron obteniendo 2,539.00, 2.294.00, 2.279.00 y 2.194.00 kilogramos por hectárea respectivamente. Los menores rendimientos correspondieron a: Trifluralina con 1,103.00 hectarea y testigo absoluto con 844.00 por hectarea. El analisis economico de los rendimientos por tratamiento, revelo que los mayores ingresos netos se obtuvieron con: testigo mecánico, Alachlor + Metribuzin, y Alachlor y Alachlor + Linuron de: 1,945.22, 1,800.12, 1,771.87 y 1,668.31 córdobas por hectárea respectivamente, pero la mayor relación beneficio-costo se logro con los tratamientos Alachlor, Alachlor + Metribuzin, testigo mecánico y Alachlor + Linuron, con 2.31, 2.30, 2.23 y 2.21 respectivamente.

Adiabatic shear localization is a mode of failure that occurs in dynamic loading. It is characterized by thermal softening occurring over a very narrow region of a material and is usually a precursor to ductile fracture and catastrophic failure. This reference source is the first detailed study of the mechanics and modes of adiabatic shear localization in solids, and provides a systematic description of a number of aspects of adiabatic shear banding. The inclusion of the appendices which provide a quick reference section and a comprehensive collection of thermomechanical data allows rapid access and understanding of the subject and its phenomena. The concepts and techniques described in this work can usefully be applied to solve a multitude of problems encountered by those investigating fracture and damage in materials, impact dynamics, metal working and other areas. This reference book has come about in response to the pressing demand of mechanical and metallurgical engineers for a high quality summary of the knowledge gained over the last twenty years. While fulfilling this requirement, the book is also of great interest to academics and researchers into materials performance.

A Sessão do Plenário da Constituinte começou com os líderes de diversos partidos se revesando na tribuna a favor e contra a proposta do Centrão para a mudança do Regimento Interno. Após muita confusão e debate, é posta em votação a proposta do Centrão. O líder Mário Covas comunica que o PMDB se retira da votação. O PMDB e os Partidos Progressistas se retiram e os constituintes começam a votação. O Centrão está sozinho no Plenário. As galerias do Plenário se enchem com participantes de um evento da CUT, CGT e Contag. Vaias e chuvas de papel cobrem o Centrão a cada voto. Finda a votação, a mudança do Regimento é aprovada. Diante da impossibilidade de acordo, o presidente do PMDB, sugere que a Mesa faça um substitutivo com as alterações objeto de divergência. Ulysses Guimarães sugere a apresentação de um projeto de resolução para tentar o acordo entre os constituintes. Emendas e destaques poderão aperfeiçoar a proposta aprovada pelo Centrão.
