Synthesis and biological evaluation of platinum complexes of highly functionalized aroylaminocarbo-N-thioyl prolinate containing tetrahydropyrrolo[3,4-c]pyrrole-1,3(2H,3aH)-dione moieties
Platinum complexes, derived from two families of bidentate funcionalized aroylaminocarbo-N-thyoyl prolinates, are prepared using mild conditions from prolinates, which are available via 1,3-dipolar cycloadditions. The resulting four coordinated neutral square-planar platinum(II) complexes are very stable and are fully characterized. Their structures are determined by spectroscopic and analytical methods and one of them by single crystal X-ray diffraction analysis. In this pattern, the platinum exhibits distorted square planar geometry, with cis-bond angles ranging from 89.42(2) and 94.37(6)° and trans-bond angles of 176.19(6) and 177.08(6)°, respectively. Anti(myco)bacterial and antifungal studies of all these new compounds are carried out under standardized protocols.This work is a part of Samet Belveren's ongoing PhD thesis granted by Mersin University (Project no.

Synthesis of highly functionalized 2-(pyrrolidin-1-yl)thiazole frameworks with interesting antibacterial and antimycobacterial activity
A versatile, facile and concise approach to access to highly substituted functionalized 2-(pyrrolidin-1-yl)thiazole ring system is accomplished. The efficient protocol proceeds by the reaction of corresponding racemic or enantiomerically enriched pyrrolidines and readily available benzoylisothiocyanate in acetonitrile followed by sequential reaction of readily available alpha-bromo ketones in acetone. The selectivity and good yield in the desired product is another important advantage of this reaction protocol. In a few cases, the resulting N-benzoylthiourea intermediate cyclizes spontaneously before reacting with the benzophenone component. Finally, a wide study of the biological scope of this new bisheterocyclic molecules is reported.This work is a part of Samet Belveren's ongoing PhD thesis granted by Mersin University (Project no.

A quantitative version of the non-abelian idempotent theorem
Suppose that G is a finite group and A is a subset of G such that 1_A has
algebra norm at most M. Then 1_A is a plus/minus sum of at most L cosets of
subgroups of G, and L can be taken to be triply tower in O(M). This is a
quantitative version of the non-abelian idempotent theorem.Comment: 82 pp. Changed the title from `Indicator functions in the
Fourier-Eymard algebra'. Corrected the proof of Lemma 19.1. Expanded the
introduction. Corrected typo
From Bioactive Pyrrolidino[3,4-c]pyrrolidines to more Bioactive Pyrrolidino[3,4-b]pyrrolidines via Ring-Opening/Ring-Closing Promoted by Sodium Methoxide
The process involving a rearrangement of pyrrolidino[3,4-c]pyrrolidine to another pyrrolidino[3,4-b]pyrrolidine using sodium methoxide as base is fully studied. The effects of the substituents are analyzed during the ring-opening/ring-closing sequence. Computational studies are also performed to explain the importance of susbstituents and quaternary carbons, especially when the (3-indolyl)methyl is present in the starting material. Finally, all the samples are evaluated as potential candidates for antibacterial and antimycobacterial activities.We are grateful for support from Mersin University [Project no: MEU-2017-COL-01007-M150D and BAP-SBE AKB (SB) 2012-8 YL and BAP 2015- AP2-1342].

The potential teratogenic effects of interferon beta-1a and interferon beta-1b on in vitro embryonic development
Background: Interferon beta (IFNb) was the first proven drug for the treatment of multiple sclerosis (MS). The diagnosis of MS frequently occurs in women at childbearing age (especially in twenties and thirties). Therefore, the pregnancy process is major concern for many women with MS. Data on women exposed to IFNb during pregnancy are limited. The aim of our study was to investigate the teratogenic potential of IFNb on embryonic development via embryo culture technique. Recently, this technique has been often used for determining teratogenic effect of pharmacologic drugs and potential teratogens on embryonic development.
Materials and methods: In this study, IFNb was applied to the culture medium and after 48 h of culture effects of IFNbs (1000 IU/IFNb-1a and 1000 IU/IFNb-1b) on embryonic development were morphologically investigated.
Results: According to morphologic scoring system, total morphologic score, somite number and protein contents were similar between control group and two experimental groups (p > 0.05). On the other hand, yolk sac diameter, crown- -rump length and head length were significantly decreased in two experimental groups compared with control group (p < 0.05).
Conclusions: Consequently, IFNb-1a and IFNb-1b, applied to the culture medium, have no macroscopic teratogenic effect on embryonic development. However, in respect of morphometric measurements, IFNb-1a and IFNb-1b have caused growth retardation in embryo. This research related to interferon was the first study using vitro embryo culture technique; thus, in our point of view, future studies which will be performed by using different doses of IFN will contribute to the literature
Metastatic cancer versus sarcoidosis in a geriatric patient: A never-ending pitfall for clinicians
Weakly almost periodic functionals on the measure algebra
It is shown that the collection of weakly almost periodic functionals on the convolution algebra of a commutative Hopf von Neumann algebra is a C*-algebra. This implies that the weakly almost periodic functionals on M(G), the measure algebra of a locally compact group G, is a C*-subalgebra of M(G)* = C(G)**. The proof builds upon a factorisation result, due to Young and Kaiser, for weakly compact module maps. The main technique is to adapt some of the theory of corepresentations to the setting of general reflexive Banach spaces
