Secreted Frizzled-Related Protein 5 in Serum and Urine of Post-Partum Women with Gestational Diabetes Mellitus

Secreted frizzled-related protein 5 (SFRP5) is a newly identified member of the SFRP family produced by the adipose tissue which can act as an anti-inflammatory adipokine. The aim of the study was to assess SFRP5 levels in the serum and urine of women with gestational diabetes mellitus (GDM) in the early post-partum period with reference to their laboratory test results, body composition and hydration status. The study subjects included two groups: 22 GDM patients and 24 healthy controls. Maternal body composition and hydration status were evaluated by the bioelectrical impedance analysis (BIA) method. The serum and urine SFRP5, leptin and ghrelin concentrations were determined via enzyme-linked immunosorbent assay (ELISA). No significant differences were observed between the GDM and healthy groups with regard to the serum and urine SFRP5 concentrations. In the GDM group serum and urine SFRP5 levels correlated positively. The serum SFRP5 concentrations correlated negatively with hemoglobin A1c (HgbA1c) and leptin serum levels in the controls. In the control and GDM groups the serum and urine SFRP5 levels correlated negatively with the serum ghrelin levels. It appears that ghrelin as well as SFRP5 could influence the metabolic homeostasis 48 hours after delivery. A significant correlation between concentrations of SFRP5 in the serum and urine seems to suggest that urine sampling may represent an alternative to the current standard of management i.e. blood sampling. Further research in this field is required

Are dispositional adjectives a case of transposition? : semantic effects of -liw(y) attachment to verbal bases in Polish

Celem artykułu jest identyfikacja klas czasowników bazowych w procesie derywacji przymiotników skłonnościowych w języku polskim za pomocą przyrostka -liw(y) oraz ukazanie tego procesu z szerszej perspektywy tworzenia przymiotników odczasownikowych. Przymiotniki z przyrostkiem -liwy należy traktować jako podklasę subiektowych przymiotników potencjalnych, gdyż charakteryzuje je jeden argument, który pełni funkcję subiektu względem czasownika bazowego. Różnica pomiędzy znaczeniem skłonnościowym a potencjalnym nie ma charakteru kategorialnego, lecz wskazuje na różnice w intensywności występowania wspólnej cechy, jaką jest potencjalność. Zidentyfikowano następujące klasy czasowników bazowych: nieprzechodnie czasowniki odnoszące się do komunikacji i emisji, nieprzechodnie czasowniki zwrotne odnoszące się do stanów emocjonalnych, czasowniki dekauzatywne, przechodnie czasowniki odnoszące się do stanów psychicznych, mentalnych i emocjonalnych, które można interpretować jako wewnętrzne sytuacje/stany dotyczące jednego uczestnika, nieprototypowe czasowniki przechodnie, których argumenty występują w dopełniaczu lub celowniku oraz czasowniki występujące zarówno w strukturach tranzytywnych, jak i medialnych. Skłonnościowa interpretacja przymiotnika nie pochodzi od przyrostka, lecz jest zależna od cech uczestnika sytuacji wyrażonej przez czasownik (osobowy, żywotny itd.).The paper presents the constraints on the formation of dispositional adjectives in Polish marked with the suffix -liw(y) and situates the process in a larger-scale picture of the entire class of deverbal adjectivizations. Derivatives with dispositional semantics are argued to be a subclass of Subject adjectivizations/potential adjectives since both are one-participant eventualities, the sole participant being mapped onto the subject position of the main verb. The difference between dispositional and potential semantics is not categorical but a matter of degree. The domain of this process includes intransitive verbs of communication and emission, reflexively marked intransitive verbs referring to emotional states (deponents), (reflexively marked) decausatives, verbs denoting psychological/emotional/mental experiences which syntactically may be transitive but can be viewed as one-participant internal eventualities, non-prototypical transitive verbs which take genitive- and dative-marked objects and verbal roots which alternate between transitive and middle semantics. The dispositional semantics of the adjective depends on the personal/animate or inanimate nature of the participant involved in the eventuality. Thus, it rests with the base (or partly with the nominal argument) and is not supplied by the suffix

Optical properties of charged quantum dots doped with a single magnetic impurity

We present a microscopic theory of the optical properties of self-assembled quantum dots doped with a single magnetic manganese (Mn) impurity and containing a controlled number of electrons. The single-particle electron and heavy-hole electronic shells are described by two-dimensional harmonic oscillators. The electron-electron, electron-hole Coulomb as well as the short-range electron spin-Mn spin and hole spin-Mn spin contact exchange interactions are included. The electronic states of the photo-excited electron-hole-Mn complex and of the final electron-Mn complex are expanded in a finite number of configurations and the full interacting Hamiltonian is diagonalized numerically. The emission spectrum is predicted as a function of photon energy for a given number of electrons and different number of confined electronic quantum dot shells. We show how emission spectra allow to identify the number of electronic shells, the number of electrons populating these shells and, most importantly, their spin. We show that electrons not interacting directly with the spin of Mn ion do so via electron-electron interactions. This indirect interaction is a strong effect even when Mn impurity is away from the quantum dot center.Comment: 12 pages, 10 figure

Convolution properties for certain classes of multivalent functions

AbstractRecently N.E. Cho, O.S. Kwon and H.M. Srivastava [Nak Eun Cho, Oh Sang Kwon, H.M. Srivastava, Inclusion relationships and argument properties for certain subclasses of multivalent functions associated with a family of linear operators, J. Math. Anal. Appl. 292 (2004) 470–483] have introduced the class Sa,cλ(η;p;h) of multivalent analytic functions and have given a number of results. This class has been defined by means of a special linear operator associated with the Gaussian hypergeometric function. In this paper we have extended some of the previous results and have given other properties of this class. We have made use of differential subordinations and properties of convolution in geometric function theory
