Effect of Intra-Arterial Infusion of Papaverine Hydrochloride on Brain Tissue Oxygen Pressure in the Management of Severe Vasospasm Following Aneurys…

2001

Despite considerable advances in diagnostic, surgical and interventional techniques, the overall outcome for patients with aneurysmal subarachnoid hemorrhage remains poor. Concerning perioperative course, cerebral ischaemia is one of the major factors causing secondary brain demage. The aim of all therapeutic interventions is the stabilization and maintance of cerebral blood flow and tissue oxygenation in order to prevent cerebral ischaemia and consecutively brain infarction [1].

Rapid radiation of North American desert genera of the Papaveraceae: Evidence from restriction site mapping of PCR-amplified chloroplast DNA fragments

1995

Phylogenetic relationships of a group of North American desert genera of the Papaveraceae subfam. Papaveroideae and Platystemonoideae were investigated with an RFLP analysis of three PCR-amplified chloroplast genome regions. In agreement with earlier results it was found that subfam. Platystemonoideae is nested within subfam. Papaveroideae. The group under study is characterized by a large number of generic autapomorphies but only few informative synapomorphies. This is interpreted as strong evidence for a rapid radiation event caused by major climatic changes in the past. Poor phylogenetic resolution seems to reflect biological reality and not to be an experimental artifact. There is also …

Systematics, Phylogeny, and Evolution of Papaver californicum and Stylomecon heterophylla (Papaveraceae)

2011

Abstract We present a detailed comparison of Papaver californicum and Stylomecon heterophylla, which earlier were found to be sister species and most closely related to Meconopsis cambrica + Papaver s.str. from western Eurasia. The two species of winter annuals differ mainly in the shape of their distal cauline leaves, coloration of petals and staminal filaments, and most notably morphology of the gynoecium and capsule, with Papaver californicum having a sessile stigmatic disc and Stylomecon heterophylla having a distinct style. They were earlier found to differ in ploidy, with chromosome numbers of 2n  =  28 (Papaver californicum) and 2n  =  56 (Stylomecon heterophylla). Mapped distributio…

A revision of Papaver sect. Meconidium

2010

The biennial Papaver L. sect. Meconidium Spach (Papaveraceae) is considered to contain four species: P. libanoticum Boiss. with subspp libanoticum and polychaetum (Schott & Kotschy ex Boiss.) Kadereit comb. et stat. nov., P. armeniacum (L.)DC. with subspp armeniacum, microstigmum (Boiss.) Kadereit comb. et stat. nov. and pilgerianum (Fedde) Kadereit comb. et stat. nov., P. curviscapum Nab., and P. persicum Lindl. with subspp persicum, tauricolum (Boiss.) Kadereit comb. et stat. nov. and microcarpum (Boiss.) Kadereit comb. et stat. nov. A key to species and subspecies is given, capsules and leaves of all taxa are illustrated, and distribution maps are provided.

Highly Efficient Virus-induced Gene Silencing (VIGS) in California Poppy (Eschscholzia californica): An Evaluation of VIGS as a Strategy to Obtain Fu…

2007

†Background and Aims Eschscholzia californica (California poppy) is an emerging model plant for ‘evo‐devo’ studies from the basal eudicot clade of Papaveraceae. California poppy has a relatively small genome, a short life cycle and, most importantly, it is amenable for transformation. However, since this transformation protocol is time consuming, virus-induced gene silencing (VIGS) was evaluated as a fast method to obtain functional data for California poppy genes. †Methods Commercially available California poppy plants were infiltrated with Agrobacterium tumefaciens carrying the tobacco rattle virus plasmids pTRV1 and pTRV2. pTRV2 contained part of the eschscholzia Phytoene Desaturase (EcP…

Synthesis and biological evaluation of papain-family cathepsin L-like cysteine protease inhibitors containing a 1,4-benzodiazepine scaffold as antipr…

2014

Novel papain-family cathepsin L-like cysteine protease inhibitors endowed with antitrypanosomal and antimalarial activity were developed, through an optimization study of previously developed inhibitors. In the present work, we studied the structure-activity relationships of these derivatives, with the aim to develop new analogues with a simplified and more synthetically accessible structure and with improved antiparasitic activity. The structure of the model compounds was significantly simplified by modifying or even eliminating the side chain appended at the C3 atom of the benzodiazepine scaffold. In addition, a simple methylene spacer of appropriate length was inserted between the benzod…

Worm-like artifacts in exfoliative cytology.

2006

The presence of worms in cytological smears is occasionally reported, although various other structures exist that may be confused with such parasites. We present eight worm-like artifacts observed in routine Papanicolaou smears. Recognition of these structures is important to avoid overvaluation or confusion with true worms. Diagn.
