Published: July 2009

AbstractObjective: The current study aimed to determine the frequency of sleep disturbances in women prior to adjuvant therapy for breast cancer (BCa), and whether greater sleep dysfunction uniquely predicts poorer functional outcomes.Method: We assessed subjective sleep reports and associated them with multiple indicators of psychosocial adaptation in 240 women with Stage I–III BCa before they had begun adjuvant treatment.Results: The average global score on the Pittsburgh Sleep Quality Index (PSQI) was 8.49 (SD=4.16); 54% scoring above the suggested adjusted cutoff for cancer populations of 8.0. Controlling for various medical, sociodemographic, and psychosocial covariates, multiple regression analyses revealed that higher global PSQI score was significantly associated with poorer functional well‐being, greater fatigue intensity, greater disruptions in social interactions, and lower positive states of mind. Specifically, a poorer ‘sleep efficiency’ PSQI component was associated with poorer functional quality of life and the SIP–Social Interactions subscale, while a poorer ‘sleep quality’ (SQ) PSQI component was associated with all of the outcomes except for the SIP–Recreations and Pastimes subscale.Conclusions: Results indicate consistent associations between a clinical indicator of sleep dysfunction, particularly those subscales of the PSQI comprising the ‘SQ’ component, and multiple indicators of psychosocial adaptation among women treated for BCa, independent of anxiety and depression, and suggest the value of comprehensive psychosocial interventions that consider sleep problems.

AbstractObjective: Family functioning appears to be a predictor of psychological distress among childhood cancer survivors and their family members; however, relatively little is known about patterns in those families that are psychologically at‐risk. The purpose of this study was to identify distinct clusters of families that include childhood cancer survivors, and to evaluate differences between the clusters with respect to anxiety, depression, and post‐traumatic stress symptoms (PTSS).Methods: Childhood cancer survivors and their parents (247 individuals: 88 adolescent cancer survivors, 87 mothers, and 72 fathers) completed self‐report questionnaires. Perceptions of family functioning were assessed using the Family Relationship Index and its three dimensions (cohesiveness, expressiveness, and conflict), and individuals were classified into groups via a cluster analytic approach. State‐trait anxiety, depression, and PTSS were assessed to all of the participants.Results: The individuals were classified into three types: One cluster featured high cohesiveness, high expressiveness, and low conflict (‘Supportive‐type’, n=102); a second cluster featured low cohesiveness, low expressiveness, and high conflict (‘Conflictive‐type’, n=32); and a third cluster had moderate cohesiveness, moderate expressiveness, and moderate conflict (‘Intermediate‐type’, n=113). Among the three types, an analysis of variance revealed that ‘Conflictive‐type’ members had the highest levels of PTSS, depression, and state–trait anxiety.Conclusions: These findings suggest that perceptions of family functioning are related to psychological distress in family members of childhood cancer survivors. A family‐focused intervention might be a useful approach to targeting emotional distress in these families, particularly for families with a ‘Conflictive‐type’ family member.

Assessment of ligand binding residue predictions in CASP8
Authors: López Gonzalo , Ezkurdia Iakes , Tress Michael L. 
Published: July 2009

AbstractHere we detail the assessment process for the binding site prediction category of the eighth Critical Assessment of Protein Structure Prediction experiment (CASP8). Predictions were only evaluated for those targets that bound biologically relevant ligands and were assessed using the Matthews Correlation Coefficient. The results of the analysis clearly demonstrate that three predictors from two groups (Lee and Sternberg) stand out from the rest. A further two groups perform well over subsets of metal binding or nonmetal ligand binding targets. The best methods were able to make consistently reliable predictions based on model structures, though it was noticeable that the two targets that were not well predicted were also the hardest targets. The number of predictors that submitted new methods in this category was highly encouraging and suggests that current technology is at the level that experimental biochemists and structural biologists could benefit from what is clearly a growing field.

The evaluation of spin‐density matrices within the graphically contracted function method
Authors: Gidofalvi Gergely , Shepard Ron 
Published: July 2009

AbstractAn efficient algorithm is presented to compute spin‐density matrices from wave functions expanded in a basis of graphically contracted functions (GCF). The GCFs are based on the graphical unitary group approach (GUGA), which is a “spin‐free” formulation of the electronic wave function. The spin‐density matrix elements are computed from one‐particle and two‐particle charge‐density matrix elements. The recursive algorithm allows the spin‐density matrix to be computed with O(Nωn2) total effort where NGCF is the dimension of the GCF basis and n is the dimension of the orbital basis. The scale factor ω depends on the number of electrons N and ranges from O(N0) to O(N2) depending on the complexity of the underlying Shavitt graph. Because the “spin‐free” GCF formulation eliminates the need to expand the wave function in a spin‐dependent Slater determinant basis, it is possible to treat wave functions with large numbers of electrons and orbitals. Timings are given for wave functions that correspond to determinantal expansions over 10200 in length. The implementation is applicable to arbitrary spin states and to both ground and excited electronic states. © 2009 Wiley Periodicals, Inc. Int J Quantum Chem, 2009
Syntheses, Structures, and Theoretical Studies of New Mercury Iodobismuthates: (Et4N)4(Bi4Hg2I20) and (nBu4N)2(Bi2HgI10)
Authors: Yuan Mao‐Wen , Li Long‐Hua , Chen Ling 
Published: July 2009

AbstractThe first two mercury iodobismuthates, (Et4N)4(Bi4Hg2I20) (1) and (nBu4N)2(Bi2HgI10) (2) have been synthesized by the reactions of binary BiI3 and HgI2 in a mixed solution of ethanol/acetone with the existence of different ammonia cations. The novel hexanuclear (Bi4Hg2I20)4– anion in 1 can be viewed as a dimer of the trinuclear (Bi2HgI10)2– anion in 2. The DFT calculations reveal that the band gaps of both compounds are determined only by the anionic moieties and therefore are similar, which agrees with the experimental measurements.
The Effect of Temperature onto the Crystal Structure of Thioantimonates: Solvothermal Syntheses and Crystal Structures of [Co(dien)2][Co(tren)SbS4]2·0.5H2O and {[Co(tren)]2[CoSb2S6]}·H2O

Published: July 2009

AbstractThe two new compounds [Co(dien)2][Co(tren)SbS4]2·0.5H2O (1) and {[Co(tren)]2[CoSb2S6]}·H2O (2) were synthesized applying mixtures of amines as structure directing molecules (dien = diethylenediamine; tren = tris(2‐aminoethyl)amine). Compound 1 represents a pseudo‐polymorph to the compound [Co(dien)2][Co(tren)SbS4]2·4H2O. The structure consists of the two complexes [Co(2)(dien)2]2+ and [Co(1)(tren)SbS4]– with the latter containing a [Sb(V)S4]3– anion bonded to the Co2+ cation. The central and new feature of the structure is a heterometallic [CoSb2S6] core composed of two [SbIIIS3] pyramids and a [CoS4] tetrahedron. The [CoS4] tetrahedron shares two edges with two [SbIIIS3] units. The remaining sulfur atom of the [SbIIIS3] groups are bonded to two independent [Co(tren)] complexes.
Studies on Nanostructured Bi2WO6: Convenient Hydrothermal and TiO2‐Coating Pathways

Published: July 2009

AbstractBismuth tungstate is an important conductor and photocatalyst that keeps attracting research interest due to its promising catalytic activity under visible light irradiation. The 2D Aurivillius‐type structure of Bi2WO6 promotes its tendency towards the formation of nanosheets that can be converted into hierarchically structured Bi2WO6 microspheres. As their formation mechanism varies strongly with the preparative parameters and further investigations are required, we present studies on the most direct and convenient access to Bi2WO6 nano‐architectures developed hitherto. Our one‐step approach towards this key material is based on the immediate hydrothermal reaction of Bi(NO3)3·5H2O with K2WO4 that proceeds through a mechanism that differs from the previously observed routes. These insights are essential for the development of straightforward technical processes in order to produce nanomaterials without complicated parameter adjustments. The resulting Bi2WO6 nanostructures display high photocatalytic activity under visible light irradiation. For the first time, the influence of an inorganic additive, K2SO4, is investigated in the Bi(NO3)3·5H2O/K2WO4 hydrothermal system. This paved the way to the synthesis and stabilization of other bismuth oxide‐based materials at lower temperatures. Furthermore, we developed a flexible and efficient solution‐based coating process to cover the hierarchical Bi2WO6 arrangements with a thin layer of anatase TiO2 nanoparticles.

Published: July 2009

AbstractTwo new oxidovanadium (IV) complexes: TpVO(L1) (1) and Tp*VO(pzH*)(L2) (2) [Tp = hydrotris(pyrazolyl)borate, HL1 = 5‐methyl‐1H‐pyrazole‐3‐carboxylic acid, Tp* = hydrotris(3,5‐dimethylpyrazolyl)borate, pzH* = 3,5‐dimethylpyrazole, HL2 = 5‐phenyl‐1H‐pyrazole‐3‐carboxylic acid] have been synthesized and characterized by elemental analysis and IR spectroscopy. The single‐crystal structures of the complexes shows that the vanadium ion is in a distorted octahedral environment with a N4O2 donor set in each complex. Additionally, hydrogen bonding interaction exits in both complexes. Interestingly, the molecules of 1 are held together to form a 1D hydrogen bonded polymer along the b axis, whereas complex 2 is a hydrogen bonded dimer. In addition, the catalytic activities of complexes 1 and 2 in bromination reactions in phosphate buffer with phenol red as a trap were evaluated primary by UV/Vis spectroscopy. Furthermore, ab initio calculations of complexes 1 and 2 were performed.

AbstractBackgroundPast trials have shown perioperative immunonutrition to improve the outcome for patients with gastric cancer. The present study was designed to evaluate the effect of preoperative oral immunonutrition on cellular immunity, the duration of the systemic inflammatory response syndrome (SIRS), and detailed postoperative complications in patients with gastric cancer.MethodsSixty patients with gastric cancer were randomly assigned to two groups: one group received immune‐enhanced formulas supplemented with arginine and ω‐3 fatty acids (immune‐enhancing diet (ID) group, n = 30); the other received standard formulas (conventional diet (CD) group, n = 30) for 7 days before the operation. These groups were well matched in terms of age, sex, operations, cancer stages, and intraoperative variables. The postoperative outcome was evaluated based on clinical variables, including postoperative infectious complications, noninfectious complications, and SIRS duration. In addition, the perioperative state of cellular immunity was evaluated and compared between the two groups.ResultsThe incidence of postoperative infectious complications in the ID group (6%) was significantly (p < 0.05) lower than that of the CD group (28%). The duration of SIRS in the ID group (0.77 ± 0.9 days) was significantly (p < 0.05) shorter than that in the CD group (1.34 ± 1.45 days). The postoperative lymphocyte and CD4+T‐cell counts significantly decreased (p < 0.05) in both groups. However, the number of CD4+T‐cells on preoperative day 1 and postoperative day 7 was significantly (p < 0.05) higher in the ID group than in the CD group.ConclusionsPreoperative oral immune‐enhanced formulas supplemented with arginine and ω‐3 fatty acids enhanced the immune status of the patients, reduced the duration of SIRS, and decreased the incidence of postoperative infectious complications. CD4+T‐cell immunity likely played an important role in the modulation of the postoperative immune and inflammatory response after gastrectomy.

AbstractBackgroundSmall size, high benignity rate, and sporadic nature make insulinomas suitable for laparoscopic resection. On the other hand, occult location or multicentricity mandate open surgery. This study was designed to analyze a series of patients who had pancreatic insulinomas and underwent initial treatment at our institution.MethodsClinical records of the 34 patients with pancreatic insulinomas who underwent surgical resection between 1995 and 2007 were reviewed. Main variables for analysis were cure of the disease and surgical complications.ResultsThere were 20 women and 14 men with a mean age of 40 ± 13 years. Mean size of the tumors was 2.2 ± 1 cm. Laparoscopic resection was completed in 14 of 21 patients. Most tumors that were resected by laparoscopy were solitary, benign, and located in the body and tail of the pancreas. Open surgery was selected for 13 patients, including 7 sporadic (5 in the head), 4 related to the MEN syndrome, and 2 malignant tumors. Surgical morbidity occurred in 23 patients. The most common complication was pancreatic fistula (3/13 in open, 4/14 in laparoscopic, and 6/7 in conversions). One patient in the open group died 15 days after surgery from massive PTE. Postoperative normoglycemia was achieved in all patients and persisted for a follow‐up period of 4 ± 3.7 years.ConclusionsMost insulinomas in our series were small and benign. Tumors that were located in the body and tail were more often amenable for laparoscopic resection. The cure rate was very high. Pancreatic fistula was the most frequent complication.

Published: July 2009

SummaryBackground: With improvements in the treatment of children with organic acidaemias (OA), the number surviving to adulthood is increasing. To plan appropriate services for their care it is important to know what their needs are. Objective: To describe the clinical and social problems affecting adult patients with OA. Patients and methods: We reviewed the medical records of 15 adult patients diagnosed with OA. Social attainment (housing, schooling and occupation) was analysed. Nutritional status was evaluated by body mass index (BMI) and laboratory studies. Neurological and visceral complications were noted. Cognitive outcome was evaluated by psychometric testing and/or educational attainment. Results: Seven had methylmalonic acidaemia (MMA), 4 isovaleric acidaemia (IVA) and 4 propionic acidaemia (PA). Ten were female, and median age was 23.5 years (range 18–48). All but three had late‐onset disease. Two patients became pregnant during follow up. Four patients had obtained university degrees and were working. Three‐quarters of the patients required some kind of social support. All had a good nutritional status. Height was normal in IVA and 3 PA patients. Osteoporosis was present in 2 out of 8 patients assessed. A variety of neurocognitive or visceral complications were seen in two‐thirds of the patients. Metabolic decompensations were unusual. Conclusions: The approach to adult patients with OA has to be multidisciplinary, with the clinician and dietician as the core of the team, but with the collaboration of clinical nurses specialists, social workers and other specialist services and the support of a biochemical and molecular laboratory.

AbstractWe used survey data collected from a large plot (20 ha) of sub‐tropical forest in the Dinghushan Nature Reserve, Guangdong Province, southern China, in 2005 to test the comparative performance of nine species‐richness estimators (number of observed species, three species‐individual curve models, five nonparametric estimators). As the true species richness, we used the 210 free‐standing shrub and tree species of >1 cm diameter at breast height recorded during the survey. This true species richness was then used to calculate performance measures of bias, accuracy, and precision for each estimator, whereby we distinguished performance for low, medium, and high sampling intensity. Unsurprisingly, all estimators performed better than the number of observed species in terms of bias and accuracy. Surprisingly, however, two curve models (logistic and logarithm) outperformed all other estimators in terms of bias, accuracy, and precision, which is in contrast to most other previous studies, in which nonparametric methods usually outperform curve models. Intriguingly, relative estimator performance changed between low, medium, and high sampling intensity, sometimes dramatically, reinforcing the assertion that the influence of sampling intensity on estimator performance is an important aspect to investigate and to consider when choosing estimators for ecological surveys. Because these results are based on only one dataset, the results should be treated with caution, both because (1) the generality of these results needs to be confirmed with simulated datasets and (2) more work is needed to establish what “true” species richness is extrapolated by each of the tested estimators in both the statistical and the practical sense. Nevertheless, the two curve estimators, namely Logistic and Logarithm, should be considered in future studies of comparative performance of species‐richness estimators because of their outstanding performance in this study.

Abstract
Mesoporous silica with KIT-6 structure was investigated as a preconcentrating material in chromatographic systems for ammonia and trimethylamine. Its adsorption capacity was compared to that of existing commercial materials, showing its increased adsorption power. In addition, KIT-6 mesoporous silica efficiently adsorbs both gases, while none of the employed commercial adsorbents did. This means that KIT-6 Mesoporous silica may be a good choice for integrated chromatography/gas sensing micro-devices.

AbstractCCN3 expression was observed in a broad variety of tissues from the early stage of development. However, a kind of loss of function in mice (CCN3 del VWC domain ‐/‐) demonstrated mild abnormality, which indicates that CCN3 may not be critical for the normal embryogenesis as a single gene. The importance of CCN3 in bone marrow environment becomes to be recognized by the studies of hematopoietic stem cells and Chronic Myeloid Leukemia cells. CCN3 expression in bone marrow has been denied by several investigations, but we found CCN3 positive stromal and hematopoietic cells at bone extremities with a new antibody although they are a very few populations. We investigated the expression pattern of CCN3 in the cultured bone marrow derived mesenchymal stem cells and found its preference for osteogenic differentiation. From the analyses of in vitro experiment using an osteogenic mesenchymal stem cell line, Kusa‐A1, we found that CCN3 downregulates osteogenesis by two different pathways; suppression of BMP and stimulation of Notch. Secreted CCN3 from Kusa cells inhibited the differentiation of osteoblasts in separate culture, which indicates the paracrine manner of CCN3 activity. CCN3 may also affect the extracellular environment of the niche for hematopoietic stem cells.

AbstractObjectiveTo qualitatively explore potential mechanisms that may confer heightened risk for HIV infection among survivors of sex trafficking in India.MethodsCase narratives of 61 repatriated women and girls who reported being trafficked into sex work and were receiving services at an NGO in Mysore, India, were reviewed. Narratives were analyzed to examine potential sources of HIV risk related to sex trafficking.ResultsParticipants were aged 14–30 years. Among the 48 women and girls tested for HIV, 45.8% were HIV positive. Narratives described very low levels of autonomy, with control exacted by brothel managers and traffickers. Lack of control appeared to heighten trafficked women and girls' vulnerability to HIV infection in the following ways: use of violent rape as a means of coercing initiation into sex work, inability to refuse sex, inability to use condoms or negotiate use, substance use as a coping strategy, and inadequate access to health care.ConclusionSex trafficked women and girls lack autonomy and are rendered vulnerable to HIV infection through several means. Development of HIV prevention strategies specifically designed to deal with lack of autonomy and reach sex‐trafficked women and girls is imperative.
