    Description: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

    Description: Group B streptococci are common causative agents of early-onset neonatal sepsis (EOS). Pharmacokinetic (PK) data for penicillin G have been described for extremely preterm neonates but have been poorly described for late-preterm and term neonates. Thus, evidence-based dosing recommendations are lacking. We describe the PK of penicillin G in neonates with a gestational age (GA) of ≥32 weeks and a postnatal age of 〈72 h. Penicillin G was administered intravenously at a dose of 25,000 or 50,000 IU/kg of body weight every 12 h (q12h). At steady state, PK blood samples were collected prior to and at 5 min, 1 h, 3 h, 8 h, and 12 h after injection. Noncompartmental PK analysis was performed with WinNonlin software. With those data in combination with data from neonates with a GA of ≤28 weeks, we developed a population PK model using NONMEM software and performed probability of target attainment (PTA) simulations. In total, 16 neonates with a GA of ≥32 weeks were included in noncompartmental analysis. The median volume of distribution ( V ) was 0.50 liters/kg (interquartile range, 0.42 to 0.57 liters/kg), the median clearance (CL) was 0.21 liters/h (interquartile range, 0.16 to 0.29 liters/kg), and the median half-life was 3.6 h (interquartile range, 3.2 to 4.3 h). In the population PK analysis that included 35 neonates, a two-compartment model best described the data. The final parameter estimates were 10.3 liters/70 kg and 29.8 liters/70 kg for V of the central and peripheral compartments, respectively, and 13.2 liters/h/70 kg for CL. Considering the fraction of unbound penicillin G to be 40%, the PTA of an unbound drug concentration that exceeds the MIC for 40% of the dosing interval was 〉90% for MICs of ≤2 mg/liter with doses of 25,000 IU/kg q12h. In neonates, regardless of GA, the PK parameters of penicillin G were similar. The dose of 25,000 IU/kg q12h is suggested for treatment of group B streptococcal EOS diagnosed within the first 72 h of life.

    Notes: [Auszug] Botanical evidence has so far not been forthcoming from the East African area, but some palynologists are at present engaged in the analyses of a number of pollen containing cores from Ruanda-Urundi, Uganda, Kenya and south Tanganyika. I am carrying out my work mainly in the last two areas and have ...

    Notes: In a multicentre trial, 120 patients with endoscopically diagnosed duodenal ulcer were randomly allocated to treatment with either 35 μg enprostil b.d. or 400 mg cimetidine b.d. for up to 6 weeks on a double-blind basis. After 6 weeks, 82% (42/51) of enprostil-treated patients and 92% (44/48) of cimetidine-treated patients were healed. Corresponding healing figures on an intention-to-treat basis were 70% and 76%. No significant differences were detected between treatments with respect to healing rates or symptom control at any time. Side-effects were reported by 14 patients taking enprostil and 17 patients taking cimetidine; none were serious but they resulted in withdrawal of one and two patients respectively. Enprostil was found to be similar in efficacy and tolerance to cimetidine.
