de Rham cohomology of local cohomology modules: The graded case
Authors: Puthenpurakal Tony J. 
Published: January 2015

AbstractLet K be a field of characteristic zero, and let R = K[X1,… ,Xn]. Let An(K) = K⟨X1,… ,Xn,∂1,… ,∂n⟩ be the nth Weyl algebra over K. We consider the case when R and An(K) are graded by giving deg Xi = ωi and deg ∂i = –ωi for i = 1,…,n (here ωi are positive integers). Set . Let I be a graded ideal in R. By a result due to Lyubeznik the local cohomology modules are holonomic (An(K))-modules for each i≥0. In this article we prove that the de Rham cohomology modules are concentrated in degree —ω; that is, for j ≠ –ω. As an application when A = R/(f) is an isolated singularity, we relate to Hn-1(∂(f);A), the (n – 1)th Koszul cohomology of A with respect to ∂1(f),…, ∂n(f).

Authors: Ohsugi Hidefumi , Hibi Takayuki 
Published: January 2015

AbstractThe concept of centrally symmetric configurations of integer matrices is introduced. We study the problem when the toric ring of a centrally symmetric configuration is normal and when it is Gorenstein. In addition, Gröbner bases of toric ideals of centrally symmetric configurations are discussed. Special attention is given to centrally symmetric configurations of unimodular matrices and to those of incidence matrices of finite graphs.

Published: January 2015

Abstract
Two fulleropyrrolidine derivatives with the benzophenone moiety were synthesized based on a molecular design that suppresses their crystallization. The organic photovoltaic devices using the fulleropyrrolidine derivatives showed higher thermal stability than the devices using [6,6]-phenyl C61-butyric acid methyl ester. Solid-state nuclear magnetic resonance studies revealed that the benzophenone moiety reduced the domain sizes of the fullerene derivatives in the bulk heterojunction.

Published: January 2015

Abstract
The intrinsic fluorescence of a typical small amine-containing molecule, tributylamine, was first studied in polar and nonpolar solvents. The big differences in emission intensity and maximum wavelength position can be ascribed to solvation effect and solvent-induced aggregation in the different kinds of solvents.

Published: January 2015

Abstract
Flower-like BiOClxIy solid solution microspheres were synthesized with a 2:1 molar ratio of chloride (Cl) to iodine (I) by a solvothermal method. The surface area of such a sample is 52.26 m2 g−1, which is at least 10 times larger than that of an individual BiOX. When used as an adsorbent for the removal of organic dyes, the microsphere exhibited notably higher adsorption ability than the individual BiOX. The adsorption efficiency could reach nearly 100% within 10 min. Relevant characterization revealed that the microsphere consisted of accumulated nanosheets.

CelCelem pracy była ocena, czy natężenie lęku jako stanu przed operacją alloplastyki kolana uzależnione jest od funkcji stawu kolanowego.MetodaBadaniem objęto 81 chorych zakwalifikowanych do protezoplastyki kolana z powodu zaawansowanych zmian zwyrodnieniowych. Funkcję stawu oceniano przy pomocy kwestionariuszy Knee Society Score i Oxford, a natężenie lęku badano w przeddzień operacji Inwentarzem Stanu i Cechy Lęku C. D. Spielbergera.WynikiChorzy z podwyższonym lękiem jako cechą mieli większe natężenie przedoperacyjnego lęku jako stanu. Do grupy o podwyższonym lęku jako cechy należały przede wszystkim osoby starsze. Ponadto u tych chorych funkcja kolana była gorsza. W badaniu stwierdzono, że im lepszy przed operacją był stan kliniczny i funkcja kolana, tym wyższy był przed operacją poziom lęku jako stanu.Wnioski1. Stan kliniczny kolana przed operacją wszczepienia protezy oraz lęk jako cecha są predyktorami występowania przedoperacyjnego lęku jako stanu. 2. Wśród chorych przed alloplastyką kolana poziom lęku jako cechy jest wyższy u osób starszych. 3. Przed operacją gorszy stan kliniczny kolana występował u osób z wykształceniem podstawowym w porównaniu do osób z wykształceniem średnim i wyższym. 4. Nie stwierdzono istotnej statystycznie korelacji między przedoperacyjnym lękiem a płcią, statusem pracy i stanem cywilnym chorych.

CelCelem badania była odpowiedź na pytanie czy aktywność fizyczna w trakcie ciąży oraz uczestnictwo w zajęciach w Szkole Rodzenia przygotowuje kobiety do porodu oraz wpływa na poziom postrzeganego stresu i występowanie u nich objawów obniżonego nastroju.MetodaBadania przeprowadzono wśród 100 kobiet, z których połowa uczestniczyła przed porodem w zajęciach Szkoły Rodzenia. Do przeprowadzenia badań wykorzystano ankietę własnego autorstwa, Edynburską Skalę Depresji Poporodowej (EPDS) oraz Skalę Postrzeganego Stresu (PSS-10).WynikiNie stwierdzono istotnej zależności między uczestniczeniem w zajęciach w Szkole Rodzenia a wynikami EPDS i PSS-10. Nastrój kobiet po porodzie korelował istotnie z poziomem odczuwanego stresu w całej badanej grupie (p<0,0001). Najlepsze średnie samopoczucie i najniższy średni odczuwany stres prezentowały kobiety pozostające w związku (p=0,0029, p=0,0008). Kobiety aktywne fizycznie charakteryzowały się również lepszym samopoczuciem i mniejszym poziomem odczuwanego stresu (odpowiednio 6,7 i 14,4 vs. 8,4 i 16,0). Wśród kobiet ćwiczących w czasie ciąży zdecydowanie liczniejsze były uczestniczki zajęć w Szkole Rodzenia (p<0,0001).WnioskiDeklarowana aktywność fizyczna w czasie ciąży była związana z niższym poziomem odczuwanego przez kobiety stresu oraz mniejszym nasileniem objawów depresyjnych po porodzie, szczególnie w grupie uczestniczek zajęć Szkoły Rodzenia.

CelZbadanie wpływu psychoedukacji grupowej w zaburzeniach dwubiegunowych na wybrane aspekty poznawczej reprezentacji choroby.Metoda51 pacjentów z rozpoznaniem zaburzeń dwubiegunowych włączono do badania, a 24 do ostatecznej analizy statystycznej. Uczestnicy wzięli udział w 8 spotkaniach grupowej psychoedukacji. Poddano ich trzykrotnej (przed, po i w 18 miesięcy po interwencji) ocenie za pomocą kwestionariuszy badających wybrane aspekty poznawczej reprezentacji choroby: akceptację choroby, umiejscowienie kontroli zdrowia, uogólnioną własną skuteczność, nadzieję na sukces, współpracę terapeutyczną, przekonania wobec zaburzeń dwubiegunowych, w celu zarejestrowania ewentualnych zmian po zastosowaniu psychoedukacji.WynikiWykazano istotny statystycznie wzrost w zakresie poziomu akceptacji choroby, spostrzeganej własnej skuteczności, poziomu nadziei na sukces, współpracy w zażywaniu leków normotymicznych, a także korzystną modyfikację przekonań na temat zaburzeń dwubiegunowych. Zaobserwowana zmiana wystąpiła zaraz po zakończeniu oddziaływań i nie utrzymała się w czasie okresu obserwacyjnego.WnioskiPsychoedukacja może wywierać korzystny wpływ na potencjalnie ważne z punktu widzenia efektów leczenia zaburzeń dwubiegunowych zmienne poznawcze. Wpływ ten może zanikać w czasie, stąd oddziaływania powinny być powtarzane lub czas trwania interwencji wydłużony. Badanie wyznacza możliwe dalsze kierunki prac badawczych w obszarze poszukiwania mechanizmów działania psychoedukacji oraz aktywnych komponentów stosowanych interwencji.

Published: January 2015

CelCelem badania była ocena związku między stężeniem homocysteiny (HCY), witaminy B12 i kwasu foliowego, a zaburzeniami funkcji poznawczych w okresie ostrego epizodu depresji w przebiegu choroby afektywnej dwubiegunowej (CHAD).MetodaW badaniu uczestniczyło 116 osób (93 kobiety, 23 mężczyzn), w wieku od 20 do 78 (średnio 51±13) lat, z epizodem depresyjnym w przebiegu CHAD. Do określenia stanu psychicznego posłużyła 17-itemowa Skala Depresji Hamiltona (HDRS). Zastosowano testy badające wybiórcze sprawności poznawcze: Test Łączenia Punktów, Test Sortowania Kart Wisconsin, Test Stroopa i Skala Inteligencji Wechslera (WAIS-R). U wszystkich pacjentów wykonano oznaczenia poziomu homocysteiny, witaminy B12 i kwasu foliowego w surowicy krwi.WynikiHiperhomocysteinemię (HCY > 15µM/l) stwierdzono u 41 osób (35%), częściej mężczyzn (52%) niż kobiet (31%). Pacjenci z hiperhomocysteinemią osiągnęli gorsze wyniki w podtestach WAIS-R (rozumienie werbalne i organizacja percepcyjna). U mężczyzn stwierdzono ujemną korelację między stężeniem HCY, a liczbą błędów w teście Stroopa B i teście Wisconsin (ogólna liczba i błędy nieperseweracyjne). U kobiet z CHAD typu II ujemna korelacja dotyczyła stężenia HCY i czasu wykonania testu Stroopa B oraz stężenia witaminy B12 i liczby błędów w teście Stroopa A. W całej grupie oraz grupie mężczyzn stwierdzono dodatnią korelację między liczbą błędów w teście Stroopa B, a wyższym stężeniem kwasu foliowego.WnioskiUzyskane wyniki wskazują na istnienie podwyższonego stężenia HCY u znacznej części pacjentów w depresji CHAD, zwłaszcza w grupie mężczyzn. Potwierdzają również związek wysokiego stężenia homocysteiny z gorszym wykonaniem testów neuropsychologicznych w różnych obszarach funkcji poznawczych. Zależność taka wyrażona jest w większym stopniu u mężczyzn.
Short and Long Interpregnancy Intervals: Correlates And Variations by Pregnancy Timing Among U.S. Women
Authors: Cheslack Postava Keely , Winter Alix S. 
Published: January 2015

CONTEXTShort and long interpregnancy intervals are associated with adverse health outcomes. Little is known about the correlates of short and long interpregnancy intervals in the general population, and whether correlates vary by pregnancy intention.METHODSData on 10,236 pregnancies following a live birth were drawn from the 1995, 2002 and 2006–2010 waves of the National Survey of Family Growth. Logistic regression was used to assess characteristics associated with women's reporting short interpregnancy intervals (less than 12 months) and long intervals (greater than 60 months). Analyses were stratified by whether women considered their pregnancies well timed or mistimed.RESULTSThirty‐one percent of pregnancies following short intervals and 47% following long intervals were well timed. Among well‐timed pregnancies only, the odds of short intervals were elevated if women had been 35 or older, rather than aged 20–29, at last pregnancy (odds ratio, 2.3); if their prior infant had died (10.6); or if they had wanted their prior pregnancy sooner than it had occurred (2.2). Overall, the odds of long intervals were higher among minority groups than among whites (1.4–1.6) and were lower among women who had been 30 or older at prior pregnancy than among those who had been in their 20s (0.1–0.5); they increased with level of family income. Correlates of long intervals generally varied little by intention.CONCLUSIONSAlthough the majority of pregnancies at short intervals are unintended, specific subsets of women have elevated odds of intending short interpregnancy intervals.
A Model of the Academic Review Process with Informed Authors
Authors: Azar Ofer H. 
Published: January 2015

Abstract
Research on the academic review process may help to improve research productivity. The article presents a model of the review process in a top journal, in which authors know their paper’s quality whereas referees obtain a noisy signal about quality. Increased signal noisiness, lower submission costs and more published papers all reduce the average quality of published papers in the journal. The model allows analyzing how the submission cost, the accuracy of referees and the number of published papers affect additional equilibrium characteristics. Implications of the model for journal policies are also discussed.
Structural transformation and productivity in Latin America
Authors: Ferreira Pedro Cavalcanti , da Silva Leonardo Fonseca 
Published: January 2015

AbstractThis article examines the effects of sectorial shifts and structural transformation on the recent productivity path of Latin America. We use a four-sector (agriculture, industry, modern services and traditional services) general equilibrium model calibrated to the main economies in the region. The model very closely replicates labor reallocations across sectors and the growth of aggregate labor productivity from 1950 to 2005. Structural transformation explains a sizeable portion of the region’s convergence in the first decades. In most cases, the poor performance of the traditional services sector is the main cause of the slowdown in productivity growth observed in the region after the mid-1970s and is a key factor in explaining the divergence during this period.
Comparison of two methods for measuring methylmalonic acid as a marker for vitamin B12 deficiency
Authors: Obeid Rima , Geisel Jürgen , Herrmann Wolfgang 
Published: January 2015

Abstract

Background: Methylmalonic acid (MMA) is a functional marker of vitamin B12 status and a valuable diagnostic tool. The gas chromatography mass spectrometry (GCMS) MMA assay has been used for decades in clinical studies.

Methods: In this study, we compared a newly developed liquid chromatography tandem mass spectrometry assay for MMA (ClinMass® Complete Kit) with the GCMS method and further measured other relevant vitamin B12 markers (homocysteine, total B12 and holotranscobalamin) to validate the new liquid chromatography combined with tandem mass spectrometry (LC-MS/MS) method. For this purpose, 138 samples that were sent to our routine laboratory total B12 assay were used.

Results: The GCMS and LC-MS/MS assays showed a strong correlation (r=0.92, p<0.001) particularly at low holoTC levels (deficiency is more probable). Forty six cases had MMA>300 nmol/L with both methods. Only five subjects showed MMA GCMS>300 nmol/L, but MMA LC-MS/MS≤300 nmol/L. However, the LC-MS/MS method showed a slightly better correlation with other B12 markers (holoTC, total B12). In addition, the LC-MS/MS method offers several advantages over the GCMS method, such as saving time and costs, precision, flexibility and popularity in modern labs.

Conclusions: The new LC-MS/MS assay for MMA showed an excellent correlation to the GCMS method. The two methods showed similar agreements with other vitamin B12 markers.
Making the LINC: SUN and KASH protein interactions
Authors: Kim Dae In , KC Birendra , Roux Kyle J. 
Published: January 2015

AbstractCell nuclei are physically integrated with the cytoskeleton through the linker of nucleoskeleton and cytoskeleton (LINC) complex, a structure that spans the nuclear envelope to link the nucleoskeleton and cytoskeleton. Outer nuclear membrane KASH domain proteins and inner nuclear membrane SUN domain proteins interact to form the core of the LINC complex. In this review, we provide a comprehensive analysis of the reported protein-protein interactions for KASH and SUN domain proteins. This critical structure, directly connecting the genome with the rest of the cell, contributes to a myriad of cellular functions and, when perturbed, is associated with human disease.
HIV testing among non-incarcerated substance-abusing juvenile offenders
Authors: Tolou-Shams Marina , Conrad Selby , Louis Alaina , Shuford Sarah Hart , Brown Larry K. 
Published: January 2015

Abstract
Juvenile offenders are a subgroup of adolescents at particular risk for HIV/STI infection. Although HIV prevalence among these youth is low (<1%) in the US, rates of other STIs, unprotected sexual activity, multiple partners, and incidents of substance use during sex are high compared with other adolescent populations. Many of these youth will enter the adult criminal justice system, which is known to have an extremely high rate of HIV infection. US constitutional mandates provide HIV/STI testing for incarcerated juveniles, but close to 80% of juvenile arrestees are never detained. Moreover, although they engage in similar HIV risk behaviors as those detained, they have limited access to available HIV/STI testing services. Thus, our study examined rates of lifetime HIV testing among a pilot sample of 60 court-involved, substance-using juveniles monitored in the community to explore rates of testing and the reasons related to lifetime testing among a high-risk, yet understudied US juvenile population.
Perceptions of family styles by adolescents with eating disorders and their parents
Authors: Fisher Martin , Bushlow Megan 
Published: January 2015

Abstract
Purpose: The traditional view has been that there is a great deal of rigidity and enmeshment in the families of adolescents with eating disorders, with poor communication and satisfaction among family members. We used the Family Adaptability and Cohesion Evaluation Scales IV (FACES-IV) to study whether this traditional view remains true or whether family styles among those with eating disorders have changed over time to include a wider range of families.
Methods: Forty-four patients (aged 14–18 years; mean, 15.4 years; 38 females and 6 males) being treated for an eating disorder in a Division of Adolescent Medicine completed the FACES-IV questionnaire, along with the Beck Depression Inventory (BDI). Patients were diagnosed with anorexia nervosa (38.6%), eating disorders not otherwise specified (59.5%), and bulimia nervosa (2.3%) according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. They had a mean BMI of 19.6 at the time of questionnaire completion, which was an average of 175 days from first visit. Parents (38 mothers and 6 fathers) completed the FACES-IV and the BDI at the same visit without conferring with their children.
Results: A great majority of patients and parents reported their families as being connected/very connected (93% of patients and 98% of parents) and flexible/very flexible (80% and 93%), with low/very low enmeshment (89% and 89%), moderate/low/very low rigidity (77% and 95%), low/very low chaos (84% and 86%), and moderate/high/very high communication (85% and 50%). Despite these scores, all well within the normal range for families with teenagers, 70% of patients and 64% of parents reported low/very low satisfaction with their families, well below the normal range. Depression scores were moderate/severe for 44% of patients and 14% of parents. Analysis of variance and t-tests showed no differences between FACES-IV scores and age, gender, ethnicity, diagnosis, and time from first visit for patients, whereas patients and parents who were more depressed were each more likely (p<0.05) to report greater dissatisfaction with their families.
Conclusion: A great majority of patients with eating disorders and their parents reported their family styles to be in the healthy range. However, many patients and parents, especially those with depression, expressed dissatisfaction with their families. These data demonstrate that older concepts of the families of adolescents with eating disorders need to be reconsidered.
