Neurogenic characteristics of placental stem cells in preeclampsia

Preeclampsia is associated with perinatal brain injury. Autologous placenta stem cell transplantation represents a promising future treatment option for neuroregeneration. The aim of this study was to compare the neuroregenerative capacity of preeclampsia-placenta stem cells to previously characterized placentas from uncomplicated pregnancies.

Homing of placenta-derived mesenchymal stem cells after perinatal intracerebral transplantation in a rat model

The aim of this study is to assess early homing of placenta-derived stem cells after perinatal intracerebral transplantation in rats.

The quest for planarizing distortions in hydrocarbons: two stereoisomeric 4.5.5.5 fenestranes

According to semiempirical calculations the planarizing distortions in the central C(C)4 substructure of fenestranes, represented as 1, can be enhanced by a variety of structural modifications. Based on these results we selected the 7-hydroxy-c,c,c,c- and c,t,c,c[4.5.5.5]fenestranones 13 and 16 as precursors for the introduction of a bridgehead double bond. The efficient synthesis of these precursors and their chemical transformations are reported. Attempts to activate the hydroxyl group in 16 for introduction of a bridgehead double bond led to the rearrangement of the [4.5.5.5]fenestrane to a triquinacane skeleton. (C) 2011 Elsevier Ltd.

Synthesis and reactions of two stereoisomeric 4.5.5.5 fenestranes with bridgehead substituents

The [4.5.5.5]fenestranes 2 and 3 with two different functionalities were prepared in seven steps with overall yields of 5% and 10%, respectively. For introduction of a bridgehead double bond the removal of the tertiary hydroxy group was investigated in the two stereoisomeric hydroxyketones 12 and 15. Whereas the dehydration readily occurred in 12, a ring opening reaction was observed for 15. (C) 2011 Elsevier Ltd. All rights reserved.

Hypereosinophilia driven by GM-CSF in large-cell carcinoma of the lung

In contrast to leukocytosis, paraneoplastic hypereosinophilia is uncommon in lung cancer. We present a patient with large-cell carcinoma of the lung, in which cancer cells generate large amounts of GM-CSF leading to a leukemoid reaction with prominent hypereosinophilia and potentially involved in autocrine tumor stimulation.
