History of Arachis Including Evidence of A. hypogaea L. Progenitors
Authors: Simpson C. E. , Krapovickas A. , Valls J. F. M. 
Published: April 2010

Abstract
The genus Arachis L. probably originated as a geocarpic form of Stylosanthes Sw. on the old Brazilian Shield in what is now southwestern Mato Grosso do Sul, Brazil or northeastern Paraguay. Several mid-Tertiary uplifts followed, raising the penaplain and the ancient Arachis with it. The two most ancient species are still found in the area today, comprising the taxonomic section Trierectoides Krapov. and W.C. Gregory. From this beginning the other species and sections evolved as the shield was uplifted and eroded by the tributaries. The more advanced species, but still quite ancient, are in sections Extranervosae Krapov. and W.C. Gregory, Triseminatae Krapov. and W.C. Gregory, Heteranthae Krapov. and W.C. Gregory, and Erectoides Krapov. and W.C. Gregory. The evolution and distribution of these species was a slow process because of the geocarpic fruit, which would have limited movement to an estimated 1 m/yr. However, after several geologic uplifts, flowing water likely played a large part in the distribution of the Arachis species. From the early materials evolved the more advanced species in sections Caulorrhizae Krapov. and W.C. Gregory, Procumbentes Krapov. and W.C. Gregory, and Rhizomatosae Krapov. and W.C. Gregory. The evolution of species in the most advanced section Arachis, which includes the cultivated peanut, has overlapped the distribution of other sections, and the distribution of some members of section Arachis has been strongly affected by man. There is evidence that development of the major domesticated species, A. hypogaea L., did not occur in the wild, and extensive supportive data now exist on two other cultivated Arachis species still grown in Brazil for food and medicinal use—A. villosulicarpa Hoehne and A. stenosperma Krapov. and W.C. Gregory. Arachis hypogaea seeds likely moved to China and Africa with ancient mariners well before the time of Columbus. After discovery of the Western Hemisphere and the conquests, many forms of A. hypogaea spread to Africa and Asia. Later the cultivated peanut traveled in slave ships from Africa into the southeastern U.S., Central America, and northeast South America, thus returning modified germplasm to the Americas. No evidence has been found that native Americans brought the peanut, along with corn (Zea mays L), to the east coast of North America in pre-Columbian times.

Authors: Chowdhury Sarthak , Ray Prabuddha 
Published: April 2010

The empirical study revealed that among the various types of constraints (as perceived by the respondents) regarding the adoption of IPM technologies in the Pointed Gourd (Trichosan thes dioica Roxb.) production, the lack of knowledge of the respondents about the Economic Threshold Limit (ETL) concept ranked first closely followed by the lack of knowledge of the respondents regarding the bio-pesticides (under the category of knowledge and information constraints) in second position, the lack of knowledge of the respondents about the Integrated Pest Management (IPM) techniques ranked third position, closely followed by lack of training of the respondents on the proper use of pesticides in the fourth position. The result also showed that among six numbers of different categories of perceived constraints, knowledge and information constraints with a rank score of 2769 enjoyed first rank position, distantly followed by administrative and managerial constraints (with a rank score of 1586) in the second position, technological and communication constraints with a rank score of 1249 in the third position, socio-economic constraint (rank score of 828) in the fourth position.

Abstract
Myeloid cells play a crucial role in controlling infection. Activation of these cells needs to be tightly regulated, because their potent effector functions can damage host tissue. Inhibitory receptors expressed by immune cells play an important role in restricting immune cell activation. In this study, we have characterized a hitherto unidentified ITIM-bearing receptor that is highly expressed on human neutrophils and monocytes: signal inhibitory receptor on leukocytes-1 (SIRL-1). The chromosomal location of SIRL-1 is adjacent to the human leukocyte receptor complex on chromosome 19q13.4 and contains two ITIMs in its cytoplasmic tail. As a classical ITIM-bearing receptor, SIRL-1 is capable of inhibiting FcεRI-mediated signaling and can recruit the Src homology 2 domain-containing phosphatases Src homology region 2 domain-containing phosphatases 1 and 2. To investigate the specific involvement of the individual ITIMs in this study, mutational analysis was performed, which revealed that both ITIMs are crucial for SIRL-1 inhibitory function and phosphatase recruitment. When primary cells were stimulated in vitro, SIRL-1high monocytes produce less TNF-α than SIRL-1low monocytes. Thus, SIRL-1 is a novel inhibitory immune receptor belonging to the growing family of ITIM-bearing receptors that is implied in the regulation of phagocytes.
The Inflammasome Mediates Hyperoxia-Induced Alveolar Cell Permeability
Authors: Kolliputi Narasaiah , Shaik Rahamthulla S. , Waxman Aaron B. 
Published: April 2010

Abstract
A hallmark of hyperoxic acute lung injury is the influx of inflammatory cells to lung tissue and the production of proinflammatory cytokines, such as IL-1β; however, the mechanisms connecting hyperoxia and the inflammatory response to lung damage is not clear. The inflammasome protein complex activates caspase-1 to promote the processing and secretion of proinflammatory cytokines. We hypothesized that hyperoxia-induced K+ efflux activates the inflammasome via the purinergic P2X7 receptor to cause inflammation and hyperoxic acute lung injury. To test this hypothesis, we characterized the expression and activation of inflammasome components in primary murine alveolar macrophages exposed to hyperoxia (95% oxygen and 5% CO2) in vitro, and in alveolar macrophages isolated from mice exposed to hyperoxia (100% oxygen). Our results showed that hyperoxia increased K+ efflux, inflammasome formation, release of proinflammatory cytokines, and induction of caspase-1 and IL-1β cleavage both in vitro and in vivo. The P2X7 agonist ATP enhanced hyperoxia-induced inflammasome activation, whereas the P2X7 antagonist, oxidized ATP, inhibited hyperoxia induced inflammasome activation. In addition, when ATP was scavenged with apyrase, hyperoxia-induced inflammasome activation was significantly decreased. Furthermore, short hairpin RNA silencing of inflammasome components abrogated hyperoxia-induced secretion of proinflammatory cytokines in vitro. These results suggest that hyperoxia induces K+ efflux through the P2X7 receptor, leading to inflammasome activation and secretion of proinflammatory cytokines. These events would affect the permeability of the alveolar epithelium and ultimately lead to epithelial barrier dysfunction and cell death.
NKT Cell-Dependent Regulation of Secondary Antigen-Specific, Conventional CD4+ T Cell Immune Responses

Published: April 2010

Abstract
NKT cells are considered to be innate-like regulatory cells. However, their regulatory functions in adaptive immune responses have not been studied in detail. In this study, we investigated the immunoregulatory functions of NKT cells during the secondary phase of an Ag-specific CD4+ T cell response. When compared with OVA-specific effector CD4+ T cells adoptively transferred into NKT cell-deficient naive CD1d−/− mice, the same T cells transferred into naive CD1d+/− mice exhibited substantially stronger immune responses on OVA challenge. The enhanced immune response of the transferred CD4+ T cells in the presence of NKT cells correlated with an increase in their proliferation in vivo. In addition, T cells transferred into CD1d+/− recipients showed enhanced cytokine productions relative to T cells in CD1d−/− recipients. To elucidate the physiological relevance of the regulatory role of NKT cells in a disease setting, OVA-specific asthma was induced in recipient mice after adoptive transfer of OVA-specific CD4+ T cells. CD1d+/− recipients showed stronger asthmatic phenotypes in all indications when compared with CD1d−/− recipients. Taken together, these results suggest that NKT cells are critical for the regulation of Ag-specific, conventional CD4+ T cells during the secondary phase of an adaptive immune response.
Three‐Dimensional Atomic Force Microscopy – Taking Surface Imaging to the Next Level
Authors: Baykara Mehmet Z. , Schwendemann Todd C. , Altman Eric I. , Schwarz Udo D. 
Published: April 2010

AbstractMaterials properties are ultimately determined by the nature of the interactions between the atoms that form the material. On surfaces, the site‐specific spatial distribution of force and energy fields governs the phenomena encountered. This article reviews recent progress in the development of a measurement mode called three‐dimensional atomic force microscopy (3D‐AFM) that allows the dense, three‐dimensional mapping of these surface fields with atomic resolution. Based on noncontact atomic force microscopy, 3D‐AFM is able to provide more detailed information on surface properties than ever before, thanks to the simultaneous multi‐channel acquisition of complementary spatial data such as local energy dissipation and tunneling currents. By illustrating the results of experiments performed on graphite and pentacene, we explain how 3D‐AFM data acquisition works, what challenges have to be addressed in its realization, and what type of data can be extracted from the experiments. Finally, a multitude of potential applications are discussed, with special emphasis on chemical imaging, heterogeneous catalysis, and nanotribology.

Published: April 2010

AbstractThe non‐volatile polarization of a ferroelectric is a promising candidate for digital memory applications. Ferroelectric capacitors have been successfully integrated with silicon electronics, where the polarization state is read out by a device based on a field effect transistor configuration. Coupling the ferroelectric polarization directly to the channel of a field effect transistor is a long‐standing research topic that has been difficult to realize due to the properties of the ferroelectric and the nature of the interface between the ferroelectric and the conducting channel. Here, we report on the fabrication and characterization of two promising capacitor‐less memory architectures.
Enhancement of oral bioavailability of paclitaxel after oral administration of Schisandrol B in rats

Published: April 2010

AbstractPaclitaxel is a substrate of the efflux transporters such as P‐glycoprotein, and is mainly metabolized by the liver. Schisandrol B (Sch B), one of the active components in Schisandra, has been reported to be able to inhibit the activity of P‐gp and CYP3A. It might be possible that Sch B would alter the pharmacokinetic behavior of paclitaxel. Therefore, the purpose of this study was to investigate the effect of Sch B on the pharmacokinetics of paclitaxel administered orally and intravenously in rats. Paclitaxel were administered to rats orally (30 mg/kg) or intravenously (0.5 mg/kg) with or without the concomitant administration of Sch B (10 or 25 mg/kg). Oral pharmacokinetic parameters of paclitaxel were significantly altered when pretreated with Sch B. There were significant increases in AUC0‐24h (from 297.7±110.3 to 838.9±302.1 h*ng/ml; p<0.05) and Cmax (from 51.7±20.1 to 136.4±35.5 ng/ml; p<0.05) in the presence of Sch B (25 mg/kg). The pharmacokinetic parameters for i.v. paclitaxel were not significantly affected by Sch B in contrast to that of oral administration. Since the presence of Sch B enhanced the systemic exposure of paclitaxel, their pharmacokinetic interaction should be taken into consideration. As the oral bioavailability of paclitaxel was increased about 3‐fold in the presence of Sch B, the concomitant use of Sch B may provide a benefit in the oral delivery of paclitaxel.
