Histological study of SlNPV infection on body weight and peritrophic membrane damage of Spodoptera litura larvae
No full textSanjaya, Machmudin D, Kurniawati ND. 2010. Kajian histologis infeksi SlNPV terhadap berat badan dan kerusakan
membran peritrofik larva Spodoptera litura. Nusantara Bioscience 2: 135-140. Pengaruh infeksi SlNPV pada berat badan dan kerusakan
membran peritrofik larva Spodoptera litura Fab. telah dilakukan. Metode yang digunakan adalah analisis probit, dan berdasarkan LD 50
virus yang terinfeksi untuk mengetahui berat badan dan kerusakan pasca infeksi. Kerusakan struktur histologi yang disebabkan oleh
infeksi SlNPV (0, 315, 390, 465, 540 dan 615 PIB/mL) diamati setelah 0, 12, 24, 72 dan 96 jam pasca infeksi. Preparasi histologis
dibuat dengan metode parafin setelah fiksasi dengan larutan Bouin, kemudian diiris setebal 7 um dan diwarnai dengan Hematoxilin-
Eosin. Hasil penelitian menunjukkan bahwa paparan SlNPV menyebabkan penurunan konsumsi pangan terutama pada 540 PIB/mL
dengan rata-rata 0.1675 mg. Pengamatan deskriptif pada struktur histologi membran peritrophic yang terkena infeksi SlNPV
menunjukkan kecenderungan kerusakan, sementara pada kontrol tidak ada kerusakan sama sekali. Semakin lama paparan virion di
dalam lumen midgut maka semakin tinggi terjadinya kerusakan membran peritrofik. Kerusakan paling parah terjadi 96 jam setelah
infeksi. Hasilnya membuktikan bahwa virion haNPV dapat menghancurkan struktur histologi midgut.

The Exception That Proves the Rule: How Sodium Chelation Can Alter the Charge-Cell Binding Correlation of Fluorescein-Based Multimodal Imaging Agents
No full textIn the present study we describe and explain an aberrant behavior in terms of receptor binding profile of a fluorescein-based multimodal imaging agent for gastrin releasing peptide receptor (GRPR) visualization by elucidating a chelating mechanism on sodium ions of its fluorescent dye moiety. This hypothesis is supported by both biological results and spectroscopic analyses of different fluorescein-carrying conjugates and an equally charged set of analogous tartrazine-based GRPR-binding imaging agents. Fluorescein interacts with sodium which reduces the overall negative charge of the dye molecule by one. This reduction in apparent total net charge explains the exceptional behavior found for the fluorescein-based multimodal bioconjugate in the context of the charge-cell binding correlation hypothesis
Direct observation of Fermi-pressure-driven electron-hole plasma expansion in GaAs on a picosecond time scale
No full textApplying pump and probe differential reflection (Delta R) and transmission (Delta T) of femtosecond light pulses inr either co- or counterpropagating pump and probe geometries, a direct time of flight method with submicrometer resolution is presented. With this technique we study the density-dependent transport of photogenerated carrier plasmas perpendicular to the surface of GaAs samples for delay times 20 ps less than or equal to tau less than or equal to 1 ns. At a pump fluence of 800 mu J cm(-2) a relatively sharp charge-carrier front was observed, with high velocities of 14 x 10(5) cm/s at a delay time tau approximate to 20 ps, decreasing as v proportional to tau(-2/3) to 2 x 10(5) cm/s at tau approximate to 350 ps. The arrival times tau of the carriers at a fixed sample thickness depend on the fluence of the pump pulses F such as tau proportional to 1/F-0.45. The results are discussed in the framework of diffusive transport with a strongly density-dependent diffusivity D. The data can be described consistently with the assumption of Fermi pressure as the dominating driving force fur plasma expansion

The Missing Link in the Monogermanide Series: YbGe
No full textHigh-pressure, high-temperature synthesis at 12 GPa between 750 and 1000 °C for 30 to 300 min yields the last missing rare-earth metal monogermanide, YbGe. Powder and single-crystal X-ray diffraction measurements reveal that the compound crystallizes in a FeB-type structure (space group Pnma, a=7.901(2) Å, b=3.8981(9) Å, and c=5.873(2) Å). The results of the chemical bonding study, while supporting the presence of polyanionic Ge chains interacting with the surrounding Yb through multi-atomic polar bonds, suggest a transitional scenario between the monogermanides formed by alkaline-earth elements and those formed by trivalent rare-earth metals
Purification and kinetics of juvenile hormone esterase from the cabbage looper, Trichoplusia ni (Hubner)
No full textA method for purifying juvenile hormone esterase from the haemolymph of Trichopulsia ni (Hubner) was developed. The procedure resulted in a single protein band when electrophoresed on SDS-polyacrylamide gels. The enzyme consisted of a single polypeptide chain of mol. wt 48,000 as determined by gel electrophoresis and gel filtration chromatography. Enzyme activity was stable in 40% sucrose for more than 5 months, and unstable when exposed to charged environments at low enzyme concentration. The enzyme possessed apparent Km values of 1.13 × 10-6 and 0.402 × 10-6 M for JH I and JH III, respectively. © 1983
