Background
The identification and analysis of allelic variation are important bases for crop diversity research, trait domestication and molecular marker development. Grain tannin content is a very important quality trait in sorghum. Higher tannin levels in sorghum grains are usually required when breeding varieties resistant to bird damage or those used for brewing liquor. Non-tannin-producing or low-tannin-producing sorghum accessions are commonly used for food and forage. Tan1 and Tan2, two important cloned genes, regulate tannin biosynthesis in sorghum, and mutations in one or two genes will result in low or no tannin content in sorghum grains. Even if sorghum accessions contain dominant Tan1 and Tan2, the tannin contents are distributed from low to high, and there must be other new alleles of the known regulatory genes or new unknown genes contributing to tannin production.

Methods
The two parents 8R306 and 8R191 did not have any known recessive alleles for Tan1 and Tan2, and it was speculated that they probably both had dominant Tan1 and Tan2 genotypes. However, the phenotypes of two parents were different; 8R306 had tannins and 8R191 had non-tannins in the grains, so these two parents were constructed as a RIL population. Bulked segregant analysis (BSA) was used to determine other new alleles of Tan1 and Tan2 or new Tannin locus. Tan1 and Tan2 full-length sequences and tannin contents were detected in wild sorghum resources, landraces and cultivars.

Results
We identified two novel recessive tan1-d and tan1-e alleles and four recessive Tan2 alleles, named as tan2-d, tan2-e, tan2-f, and tan2-g. These recessive alleles led to loss of function of Tan1 and Tan2, and low or no tannin content in sorghum grains. The loss-of-function alleles of tan1-e and tan2-e were only found in Chinese landraces, and other alleles were found in landraces and cultivars grown all around the world. tan1-a and tan1-b were detected in foreign landraces, Chinese cultivars and foreign cultivars, but not in Chinese landraces.

Conclusion
These results implied that Tan1 and Tan2 recessive alleles had different geographically distribution in the worldwide, but not all recessive alleles had been used in breeding. The discovery of these new alleles provided new germplasm resources for breeding sorghum cultivars for food and feed, and for developing molecular markers for low-tannin or non-tannin cultivar-assisted breeding in sorghum.
Vorschläge für eine große Aktienrechtsreform
Authors: Habersack Mathias , Vetter Jochen 
Published: May 2024

Zusammenfassung
Seit Inkrafttreten des Aktiengesetzes vor knapp 60 Jahren haben sich die Lebenswirklichkeit der Aktiengesellschaften und das regulatorische Umfeld deutlich verändert. Der Gesetzgeber hat zwar auf diese Veränderungen mit einer großen Zahl durchaus beachtlicher Reformgesetze reagiert. Diese waren indes eher punktueller Natur und nicht selten durch Vorgaben des Unionsrechts, aber auch - man denke nur an das FISG - durch Unternehmensskandale veranlasst. Betrachtet man die Entwicklung aus einer Vogelperspektive, zeigt sich die Notwendigkeit einer großen, mehr oder weniger sämtliche Bereiche des Aktienrechts umfassenden Reform. Ein von der wissenschaftlichen Vereinigung für Unternehmens- und Gesellschaftsrecht (VGR) getragener Arbeitskreis von 26 Expertinnen und Experten des Aktienrechts hat es sich zur Aufgabe gemacht, Vorschläge zu einer großen Aktienrechtsreform zu entwickeln. Die Regelungsvorschläge nebst ausführlicher Begründung sollen zeitnah in der VGRSchriftenreihe des Verlags Dr. Otto Schmidt KG veröffentlicht werden. Nachfolgend werden die Gründe für eine große Aktienrechtsreform dargelegt und die Regelungsvorschläge zusammenfassend wiedergegeben.

Biomimetic Smart Interface Materials for Biological Applications
Authors: Sun Taolei , Qing Guangyan 
Published: March 2011

AbstractControlling the surface chemical and physical properties of materials and modulating the interfacial behaviors of biological entities, e.g., cells and biomolecules, are central tasks in the study of biomaterials. In this context, smart polymer interface materials have recently attracted much interest in biorelated applications and have broad prospects due to the excellent controllability of their surface properties by external stimuli. Among such materials, poly(N‐isopropylacrylamide) and its copolymer films are especially attractive due to their reversible hydrogen‐bonding‐mediated reversible phase transition, which mimics natural biological processes. This platform is promising for tuning surface properties or to introduce novel biofunctionalities via copolymerization with various functional units and/or combination with other materials. Important progress in this field in recent years is highlighted.
Paper Electronics

Published: March 2011

AbstractPaper is ubiquitous in everyday life and a truly low‐cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed.
Association between hybrid status and reproductive success of captive male and female rhesus macaques (Macaca mulatta) at the California National Primate Research Center (CNPRC)

Published: March 2011

AbstractThe California National Primate Research Center (CNPRC) houses more than 1,000 rhesus macaques (Macaca mulatta) of mixed Chinese–Indian ancestry. Most of these animals are kept in outdoor field cages, the colony's long term breeding resource. Since 2001, hybrids comprised between 4 and 49% of the field cage populations, but in most cases have represented a maximum of 10% of those populations. The increasing prevalence of hybrids is partly due to management efforts to distribute genetic diversity effectively and minimize genetic subdivisions. However, other factors may also contribute to the spread of hybrids within the colony, most notably variance in socio‐sexual behaviors and physical attributes. It is known that hybrids of some species exhibit heterosis, such as early maturation, that can enhance reproductive success, and anecdotal observations of mixed groups of hybrid, Indian and Chinese animals at the CNPRC suggest that hybrids are more sexually active. To determine whether hybrids experienced a reproductive advantage, a study was conducted using birth records of 5,611 offspring born in the CNPRC colony between 2003 and 2009. We found that while the degree of Chinese ancestry (DCA) appeared to influence the maturational schedule of both males and females (maturation was inversely related to proportion of Chinese ancestry), DCA had no independent effect on either male or female RS or rank. Therefore, we have found no evidence that a hybrid phenotype confers an absolute reproductive advantage in our colony. Am. J. Primatol. 73:671–678, 2011. © 2011 Wiley‐Liss, Inc.
Enhancement of graft yield and control of degradation during polypropylene maleation in the presence of polyfunctional monomer
Authors: Ni Qing‐Lin , Fan Jia‐Qi , Niu Hui , Dong Jin‐Yong 
Published: March 2011

AbstractFree‐radical initiated grafting of maleic anhydride (MAH)/polyfunctional acrylate (PFA) multimonomer system onto polypropylene (PP) via reactive extrusion was studied. The effects of PFA and initiator concentration on the grafting reaction were investigated. It was shown that PFA as a comonomer could greatly enhance MAH grafting degree, which increased monotonically as the molar ratio of PFA to MAH increased. The rheology test demonstrated that the viscosity of grafted PP was also promoted as more PFA was used. The formation of branched structure during the grafting process was proved by oscillatory shear rheological analysis. The mechanism of grafting in the presence of PFA was discussed, suggesting PFA had higher reactivity with PP macroradicals than MAH and therefore forming stabilized macroradicals, thus resulting in depression of β‐scission and favoring the formation of branched structure. Higher initiator concentration gave higher MAH grafting degree but more severe degradation. The mechanical properties of the grafted PP were comparable with those of unmodified PP. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Functionalization of plasma‐treated polymer surfaces with glycidol

Published: March 2011

AbstractThe ionic species created by the O2‐plasma treatment of poly(styrene) surfaces are able to initiate the polymerization of glycidol in the absence of any initiator. Consequently, thin hydrophilic films of poly(glycidol) are formed at the surface of oxygen plasma‐treated polymer surfaces upon treatment with glycidol. These were characterized with the aid of X‐ray photoelectron spectrometry, contact angle measurements, and scanning electron microscopy. A significant decrease of unspecific protein adsorption at the plasma‐treated glycidol‐modified surfaces was evidenced using fluorescence microscopy. © 2011 Wiley Periodicals, Inc.

AbstractFor diapause eggs of the silkworm, Bombyx mori, diapause initiation is prevented with hydrochloric acid (HCl) at around 20 h post‐oviposition while diapause status is terminated with chilling around 5°C. To investigate whether hydrogen peroxide (H2O2) and catalase expression are involved in diapause initiation and termination, the concentration of H2O2, relatively higher levels of catalase mRNA and activity of catalase were compared between (1) 20‐h‐old diapause eggs and the HCl‐treated diapause eggs, and (2) 10‐day‐old diapause eggs and the 5°C‐chilled diapause eggs. Compared to diapause eggs, the HCl‐treated eggs had significantly higher H2O2 concentrations (up from approximately 1–3 µmol/g fresh mass to 5–8 µmol/g fresh mass), higher relative level of catalase mRNA (up from 0 to 35.2%) and higher catalase activity (up from 2.51 units/mg protein to 4.97 units/mg protein) at 96 h post‐treatment. On the other hand, the 5°C chilling resulted in significant increases of H2O2 concentration (up from 0.79 µmol/g fresh mass to 5.57 µmol/g fresh mass), relative level of catalase mRNA (up from 0 to 71.4%) and catalase activity (up from 0.88 units/mg protein to 3.42 units/mg protein) within 120 days. The results obtained in this work suggest that variations of H2O2 and catalase expression in Bombyx eggs are involved in diapause initiation and termination. © 2011 Wiley Periodicals, Inc.
Prenatal administration of retinoic acid upregulates insulin‐like growth factor receptors in the nitrofen‐induced hypoplastic lung
Authors: Ruttenstock Elke , Doi Takashi , Dingemann Jens , Puri Prem 
Published: March 2011

AbstractBACKGROUND: Pulmonary hypoplasia (PH) is the main cause of mortality in newborns with congenital diaphragmatic hernia (CDH). Prenatal administration of retinoic acid (RA) stimulates alveologenesis in the nitrofen‐induced pulmonary hypoplasia. Insulin‐like growth factor receptors (IGFRs) play a crucial role in alveologenesis during lung development. We recently demonstrated that IGFRs were downregulated in later stages of lung development in the nitrofen CDH model. Several studies suggest the ability of RA to regulate insulin‐like growth factor signaling. We hypothesized that IGFRs pulmonary gene expression is upregulated after the administration of RA in the nitrofen‐induced CDH model. METHODS: Pregnant rats were exposed to either olive oil or nitrofen on day 9 (D9) of gestation. RA was given intraperitoneally on days D18, D19, and D20. Fetal lungs were dissected on D21 and divided into control, control + RA, CDH, and CDH + RA group. IGFRs gene and protein expression were determined using RT‐PCR and immunohistochemistry. RESULTS: mRNA expression levels of IGFRs were significantly increased in control + RA and CDH + RA compared with CDH group. Immunoreactivity of IGFRs was markedly increased in control + RA and CDH + RA compared with CDH lungs. CONCLUSIONS: Upregulation of pulmonary gene and protein expression of IGFRs after prenatal RA treatment in the nitrofen model suggests that RA may promote lung growth by stimulating IGFRs mediated alveologenesis.

AbstractThere are public concerns regarding possible carcinogenic or cancer‐promoting effects of radiofrequency electromagnetic fields (RF‐EMFs) because of the extensive use of wireless mobile phones and other telecommunication devices in daily life. However, so far it is unclear if non‐thermal exposure of single EMF exposure in animal studies has a direct influence on carcinogenesis. Here, carcinogenic effects of combined signal RF‐EMFs on AKR/J mice, which were used for the lymphoma animal model, were investigated. Six‐week‐old AKR/J mice were simultaneously exposed to two types of RF signals: single code division multiple access (CDMA) and wideband code division multiple access (WCDMA). AKR/J mice were exposed to combined RF‐EMFs for 45 min/day, 5 days/week, for a total of 42 weeks. The whole‐body average specific absorption rate (SAR) of CDMA and WCDMA fields was 2.0 W/kg each, 4.0 W/kg in total. When we examined final survival, lymphoma incidence, and splenomegaly incidence, no differences were found between sham‐ and RF‐exposed mice. However, occurrence of metastasis infiltration to the brain in lymphoma‐bearing mice was significantly different in RF‐exposed mice when compared to sham‐exposed mice, even though no consistent correlation (increase or decrease) was observed between male and female mice. However, infiltration occurrence to liver, lung, and spleen was not different between the groups. From the results, we suggested that simultaneous exposure to CDMA and WCDMA RF‐EMFs did not affect lymphoma development in AKR/J mice. Bioelectromagnetics 32:485–492, 2011. © 2011 Wiley‐Liss, Inc.

ABSTRACTA rapid, sensitive and specific method to quantify cyproheptadine in human plasma using amitriptyline as the internal standard (IS) is described. The analyte and the IS were extracted from plasma by liquid‐liquid extraction using a diethyl‐ether/dichloromethane (70/30; v/v) solvent. After removing and drying the organic phase, the extracts were reconstituted with a fixed volume of acetonitrile/water (50/50 v/v) + 0.1% of acetic acid. The extracts were analyzed by high performance liquid chromatography coupled to electrospray tandem mass spectrometry (LC‐MS/MS). Chromatography was performed isocratically using an Alltech Prevail C18 5 µm analytical column, (150 mm x 4.6 mm I.D.). The method had a chromatographic run time of 4 min and a linear calibration curve ranging from 0.05 to 10 ng/mL (r2 > 0.99). The limit of quantification was 0.05 ng/mL. This HPLC/MS/MS procedure was used to assess the bioequivalence of cyproheptadine in two cyproheptadine + cobamamide (4 mg + 1 mg) tablet formulations (Cobactin® [cyproheptadine + cobamamide] test formulation supplied from Zambon Laboratórios Farmacêuticos Ltda. and Cobavital® from Solvay Farma (standard reference formulation)). A single 4 mg + 1 mg [cyproheptadine + cobamamide] dose of each formulation was administered to healthy volunteers. The study was conducted using an open, randomized, two‐period crossover design with a 1‐week washout interval. Since the 90% CI for Cmax and AUCs ratios were all within the 80‐125% bioequivalence limit proposed by the US Food and Drug Administration, it was concluded that the cyproheptadine test formulation (Cobactin®) is bioequivalent to the Cobavital® formulation for both the rate and the extent of absorption of cyproheptadine.
