Abstract: A tridentate Schiff base ligand, (E)-2-(4-dimethylbenzydimino) glycylglycine (glygly-DAB), derived from the condensation of 4-Dimethylaminobenzaldehyde (DAB) and glycylglycine (glygly) together with its Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized and characterized using various physico-chemical methods including C,H,N elemental analysis, melting point determination, molar conductivity measurement, IR, 1H NMR and UV-Vis. The ligand and metal complexes were screened in vitro for antimicrobial and antifungal activities on four bacterial strains (Staphylococcus aureus, Escherichia coli, Salmonella thyphi and Pseudomonas aeruginosa) and two fungal strains (Candida albicans and Cryptococcus neoformans). glygly-DAB showed remarkable antifungal activities on all the fungal strains and antibacterial activities on one bacterial strain.

Abstract: The title compound, [N-(2-pyridylmethyl)-(L)-alanine]Co(III) thiocyanate (1) was obtained from the reaction of Co(OOCH3)2·H2O with the tridentate reduced Schiff base ligand, N-(2-pyridylmethyl)-(L)-alanine (L) and NH4SCN and characterized by elemental analysis, IR, UV-visible, TGA and single- crystal X-ray diffraction. Structural and spectroscopic analyses reveal [Co(L)2)]SCN to be monomeric with Cobalt(III) adopting a pseudo-octahedral geometry, coordinating to two reduce Schiff base ligands. In the crystal lattice, the thiocyanate anion forms an intermolecular SCN···HNamine hydrogen bond, while adjacent monomers are linked by intermolecular Ocarboxyl···HNamine···H-bonds to form a supramolecular network. This work is therefore undertaken in an

Trials , 2010, DOI: 10.1186/1745-6215-11-100
Abstract: Fifty-seven schools (86% of 66 eligible secondary schools) in Perth, Australia were recruited to the clustered (by school) randomised trial, with even randomisation to the intervention and control arms. Between 2003 and 2006, the VIP program was administered to 1,267 participants in the intervention schools, while 1,567 participants in the non-intervention schools received standard curriculum. Participants were all female and aged between 13-15 years upon recruitment. Pre and post-intervention questionnaires measured short-term impact and participants are now being followed through their teenage years via data linkage to hospital medical records, abortion clinics and education records. Participants who have a live birth are interviewed by face-to-face interview. Kaplan-Meier survival analysis and proportional hazards regression will test for differences in pregnancy, birth and abortion rates during the teenage years between the study arms.This protocol paper provides a detailed overview of the trial design as well as initial results in the form of participant flow. The authors describe the intervention and its delivery within the natural school setting and discuss the practical issues in the conduct of the trial, including recruitment. The trial is pragmatic and will directly inform those who provide Infant Simulator based programs in school settings.ISRCTN24952438The social and financial cost to the individual and to society of unintended pregnancy is substantial and giving birth as a teenager is associated with a higher risk of negative consequences for both the young mother and child [1,2]. In developed countries teenage motherhood tends to be associated with low social and economic circumstances, and high risk behaviours such as drinking, smoking and drug use [3-6]. Although a small minority of teenage mothers in late teenage years have access to good social support and financial resources, most teenage mothers and their children represent high need clients for

Abstract: Background There is increasing interest in the contribution of the quality of nursing care to patient outcomes. Due to different casemix and risk profiles, algorithms for administrative health data that identify nursing-sensitive outcomes in adult hospitalised patients may not be applicable to paediatric patients. The study purpose was to test adult algorithms in a paediatric hospital population and make amendments to increase the accuracy of identification of hospital acquired events. The study also aimed to determine whether the use of linked hospital records improved the likelihood of correctly identifying patient outcomes as nursing sensitive rather than being related to their pre-morbid conditions. Methods Using algorithms developed by Needleman et al. (2001), proportions and rates of records that identified nursing-sensitive outcomes for pressure ulcers, pneumonia and surgical wound infections were determined from administrative hospitalisation data for all paediatric patients discharged from a tertiary paediatric hospital in Western Australia between July 1999 and June 2009. The effects of changes to inclusion and exclusion criteria for each algorithm on the calculated proportion or rate in the paediatric population were explored. Linked records were used to identify comorbid conditions that increased nursing-sensitive outcome risk. Rates were calculated using algorithms revised for paediatric patients. Results Linked records of 129,719 hospital separations for 79,016 children were analysed. Identification of comorbid conditions was enhanced through access to prior and/or subsequent hospitalisation records (43% of children with pressure ulcers had a form of paralysis recorded only on a previous admission). Readmissions with a surgical wound infection were identified for 103 (4.8/1,000) surgical separations using linked data. After amendment of each algorithm for paediatric patients, rates of pressure ulcers and pneumonia reduced by 53% and 15% (from 1.3 to 0.6 and from 9.1 to 7.7 per 10,000 patient days) respectively, and an 84% increase in the proportion of surgical wound infection (from 5.7 to 10.4 per 1,000 separations). Conclusions Algorithms for nursing-sensitive outcomes used in adult populations have to be amended before application to paediatric populations. Using unlinked individual hospitalisation records to estimate rates of nursing-sensitive outcomes is likely to result in inaccurate rates.

Mathematics , 1994,
Abstract: Let $R=\bigoplus_{n\ges0}R_n$ be a graded commutative ring generated over a field $K=R_0$ by homogeneous elements $x_1,\dots,x_e$ of positive degrees $d_1,\dots,d_e$. The Hilbert-Serre Theorem shows that for each finite graded $R$--module $M=\bigoplus_{n\in\BZ}M_n$ the {\it Hilbert series\/} $\sum_{n\in\BZ}(\rank_K M_n)t^n$ is the Laurent expansion around $0$ of a rational function $$ H_M(t)=\frac{q_M(t)}{\prod_{i=1}^e(1-t^{d_i})} $$ with $q_M(t)\in\BZ[t,\ti]$. We demonstrate that Laurent expansions $\left[M\right]_z$ of $H_M(t)$ around other points $z$ of the extended complex plane $\overline\BC$ also carry important structural information.

Abstract: Multiple Osteochondromas (MO) MIM 133700Hereditary Multiple Exostoses (HME), Multiple Hereditary Exostoses (MHE), EXT, diaphyseal aclasis, (multiple hereditary) osteochondromatosis, multiple cartilaginous exostosesOsteochondroma (osteocartilaginous exostosis) is a cartilage capped bony projection arising on the external surface of bone containing a marrow cavity that is continuous with that of the underlying bone [1]. A diagnosis of MO can be made when radiologically at least two osteochondromas of the juxta-epiphyseal region of long bones are observed. In the majority of patients a positive family history and/or mutation in one of the EXT genes can be detected [2,3].The prevalence of MO is estimated at 1:50,000 persons within the general population [4] and seems to be higher in males (male-to-female ratio 1.5:1) [2,5]. This is probably due to the fact that females tend to have a milder phenotype and are therefore more easily overlooked [2]. The solitary (sporadic) form of osteochondroma is approximately six times more common than the occurrence within the context of MO. Approximately 62% of the patients with multiple osteochondromas have a positive family history [2].Osteochondromas develop and increase in size in the first decade of life, ceasing to grow when the growth plates close at puberty. They are pedunculated or sessile (broad base) and can vary widely in size. The majority are asymptomatic and located in bones that develop from cartilage, especially the long bones of the extremities, predominantly around the knee (Figures 1 and 2A). The facial bones are not affected. The number of osteochondromas may vary significantly within and between families, the mean number of locations is 15–18 [6]. In addition, in MO patients a variety of orthopaedic deformities can be found like deformities of the forearm (shortening of the ulna with secondary bowing of radius) (39–60%) [4,6,7] (Figure 2C), inequality in limb length (10–50%) [4,7], varus or valgus angulation of th

Abstract: this article is a re-examination of the lithic artifacts of las buitreras 1 cave, güer aike departament, santa cruz province, focused on the explotation of lithic raw materials for the manufacture of artifacts. the procurement strategies for rocks at the site are also discussed. the sample includes lithics from layers iv to i, which correspond to the last 4000 years bp. the explotation of nearby lithic raw materials, the predominance of tools/debris, the scarcity of primary and secondary flakes/debris, the small size of flakes and the reutilization of blanks, suggest a low investment in the procurement of rocks and the manufacture of artifacts. these results agree with the previously proposed marginal land-use model of the gallegos river basin during the late holocene.

Abstract: the analysis of stone tool from the surface of laguna cóndor (estancia glencross, santa cruz, argentina), located in the upper basin of the gallegos river, in an area known as los morros, is presented. the methodology applied, denominated minimun analitical nodules analysis (larson y kornfel 1997), has the advantage of grouping the artifacts and ecofacts by rock nodule, which is more useful than clustering them by class or type of lithic raw material. this method allows us to doing a major resolution analysis and a more detailed quantification. the results shown the predominance of nodules represen-ted by only one piece of debitage, in some cases in non-local raw materials, and by sets of debitage in immediately available lithic raw materials. according to the organization models proposed as framework to this methodology, the results point out, at frst, the resharpening of tools manufactured and discarded in another place and with a minor rate, in situ manufacture and maintenance of tools, removed of the site and transported far away. this pattern, together with other lines of evidences, suggests a logistic landscape use, at least in historic times, according to the available radiocarbon dating.

Abstract: Se presenta el análisis de los materiales líticos de superficie recuperados en la margen noreste de la laguna Cóndor (Estancia Glencross, Santa Cruz, Argentina), localizada en las nacientes del río Gallegos, en un área conocida localmente como los Morros. La metodología implementada, denominada Minimun Analitical Nodules Analysis (Larson y Kornfel 1997), permite agrupar los artefactos y ecofactos por nódulo de roca, lo cual posibilita un análisis de mayor resolución y una cuantificación más precisa de las materias primas líticas explotadas que la agrupación genérica por clase o tipo de roca. Los resultados alcanzados muestran el predominio de nódulos representados por un desecho aislado, en muchos casos en materias primas no-locales, y por conjuntos de desechos en materias primas disponibles en la inmediata vecindad. De acuerdo con los modelos de organización tecnológica propuestos como marco de esta metodología de análisis, los resultados indican, en primer lugar, la reactivación de instrumentos manufacturados y descartados en otro lado que transitaron por el sitio y, en menor proporción, la manufactura y mantenimiento de artefactos in situ que fueron transportados fuera del sitio. Este patrón, junto con otras evidencias, sugieren un uso logístico de este sector del espacio, al menos en momentos históricos, según las dataciones radiocarbónicas disponibles hasta la fecha.

Abstract: En este trabajo se presenta un reanálisis de la colección de artefactos líticos de Las Buitreras 1 (Departamento Güer Aike, provincia de Santa Cruz), poniendo la atención en la forma en que se utilizaron las materias primas líticas para la manufactura de artefactos. Asimismo, se discuten las estrategias de aprovisionamiento de rocas que se implementaron en el sitio. La muestra analizada comprende las capas IV a I, las cuales corresponden a los últimos ca. 4000 a os AP. El aprovechamiento de materias primas disponibles en la inmediata vecindad del sitio, el predominio de artefactos formatizados/desechos de talla, la escasez de lascas primarias y secundarias/total de desechos, el tama o peque o de los mismos y la reutilización de formas-base para la manufactura de artefactos indican una baja inversión en el abastecimiento de rocas y en la manufactura de artefactos. Estos resultados apoyan las propuestas previas de un uso marginal de la cuenca del río Gallegos para el Holoceno tardío. This article is a re-examination of the lithic artifacts of Las Buitreras 1 Cave, Güer Aike Departament, Santa Cruz Province, focused on the explotation of lithic raw materials for the manufacture of artifacts. The procurement strategies for rocks at the site are also discussed. The sample includes lithics from layers IV to I, which correspond to the last 4000 years BP. The explotation of nearby lithic raw materials, the predominance of tools/debris, the scarcity of primary and secondary flakes/debris, the small size of flakes and the reutilization of blanks, suggest a low investment in the procurement of rocks and the manufacture of artifacts. These results agree with the previously proposed marginal land-use model of the Gallegos river basin during the late Holocene.
