Quinqueloculares (Boiss.) Phitos (Campanulaceae) were investigated with a light microscope (LM)

and scanning electron microscope (SEM). All examined species are endemic, except Campanula crispa Lam. According to the results of this study, pollen grains of the examined taxa were triporate and spheroidal. Their sculpture was spinose and baculate (C. crispa Lam.); spinulose and microperforate (C. tomentosa Lam.); microperforate (C. vardariana Bocquet) or more commonly, microechinate (C. iconia selleck inhibitor Phitos, C. lyrata Lam. subsp. lyrata, C. hagielia Boiss., C. sorgerae Phitos, C. betonicifolia SM., C. karadjana Bocquet, C. telmessi Hub.-Mor. & Phitos, C. davisii Turrill).”
“Background: Herein we report a case of bilateral anterior ischemic optic neuropathy (AION) showing histopathologic evidence of AL-amyloidosis of the temporal arteries. It is known that light-chain (AL) amyloidosis may rarely affect the temporal arteries, mimicking giant cell arteritis, while, to our knowledge, the association between AL-amyloidosis and AION was not previously described. Case presentation: A 64 year-old woman with AL-amyloidosis secondary

to a monoclonal gammopathy of undetermined significance (MGUS) referred to our hospital for acute painless drop of vision due to bilateral AION. Age greater than 50 years, high erythrocyte sedimentation rate (ESR), and bilateral AION were suggestive of giant cell arteritis (GCA). However, a temporal artery biopsy excluded GCA, showing segmental stenosis of the lumen caused by amyloidosis of the artery wall. Conclusions: The present case shows that AL-amyloidosis may present with AION, high ESR, and temporal artery AR-13324 concentration involvement, mimicking GCA. In patients with monoclonal gammopathies, C-reactive protein may be a more specific index of GCA compared with the ESR. Patient medical history and pathology are crucial for a correct diagnosis.”
“Adenoviruses with deletion of E1b have been used in clinical trials to treat cancers that are resistant to conventional therapies. The efficacy of viral replication within cancer cells determines the results of oncolytic therapy, which learn more remains poorly understood and requires further improvement. In this report, we show

that adenoviruses induce autophagy by increasing the conversion of LC3-I to LC3-II and the formation of the Atg12-Atg5 complex. Inhibition of autophagy with 3-methyladenine (3MA) resulted in a decreased synthesis of adenovirus structural proteins, and thereby a poor viral replication; promotion of autophagy with rapamycin increased adenovirus yield. This study indicates that adenovirus-induced autophagy correlates positively with virus replication and oncolytic cell death, and that autophagy may generate nutrients that can be used for building viral progeny particles. These results further suggest that chemotherapeutic agents that increase cancer cell autophagy may improve the efficacy of oncolytic virotherapy. (C) 2011 Elsevier Inc. All rights reserved.
