Ultrastructural observations of Beauveria bassiana infection in Xylotrechus rusticus larvae
Jun‐Nan Ding,De-Fu CHI 한국곤충학회 2018 Entomological Research Vol.48 No.3
In the present study we investigated the infection process of Beauveria bassiana on Xylotrechus rusticus larvae using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM results showed that B. bassiana spores germinated on the surface of the larval body and invaded the larva as an appressorium. The hyphae then germinated from the spores and spread throughout the larval body. After the death of the larva, conidiophores formed at one end of the hypha on the surface of the larval body and prepared for a new round of infection. The TEM results showed severe damage to the larval cuticle after hyphae infection. The structure of the cuticle became thinner and eventually flocculent; muscle tissues were dissociated and eventually stuck to the hyphae, and the corpus adiposum was loose and deformed, and eventually degraded.

서한 양웅으로부터 시작하여 사마상여에 대한 평론은 중단된 적이 없었다. 평가의 초점은 “買官”, “竊色”, “劫財” 등 부분에 맞춰있다. 한초 문경시기 “자選”이라는 선관제도를 실행하였는데 사마상여의 “재물로 낭관이 되었다”는 기록은 바로 이러한 나라에서 법률로 정한 방식으로 획득한 것이므로 합법적인 것이지 매관의 문제가 존재하는 것은 아니다. 사마상여와 탁문군이 성도로 도주를 했다는 일도 당시 과부를 취할 때 “협의하여 강제 혼인을 한다”는 방식을 이용했을 뿐이지 역시 겁탈 따위의 문제가 되는 것이 아니다. 사마상여와 탁문군이 탁왕손으로부터 거액의 재산을 얻게 된 일도 대부분 당시 법률상 탁문군이 당연히 획득하게 될 내용이지 재산을 탈취했다는 문제는 존재하지 않는 것이다.

<P>Network formation: Comicellization of polystyrene-block-polyethylene oxide (PS–PEO) with non-ionic surfactants leads to the formation of networks and chains of spheres. The aqueous network solutions are responsive to dilution, undergoing morphological transformations to cylinders with Y junctions and both two- and three-dimensional toroids (see figure). <img src='wiley_img/14394235-2009-10-8-CPHC200900081-content.gif' alt='wiley_img/14394235-2009-10-8-CPHC200900081-content'> </P> <B>Graphic Abstract</B> <P>Network formation: Comicellization of polystyrene-block-polyethylene oxide (PS–PEO) with non-ionic surfactants leads to the formation of networks and chains of spheres.

An integrated bioinformatics analysis of mouse testis protein profiles with new understanding
( Fu Jun Liu ),( Hai Yan Wang ),( Jian Yuan Li ) 생화학분자생물학회(구 한국생화학분자생물학회) 2011 BMB Reports Vol.44 No.5
The testis is major male gonad responsible for spermatogenesis and steroidogenesis. Much knowledge is still remained to be learned about the control of these events. In this study, we performed a comprehensive bioinformatics analysis on 1,196 mouse testis proteins screened from public protein database. Integrated function and pathway analysis were performed through Database for Annotation, Visualization and Integrated Discovery (DAVID) and ingenuity Pathway Analysis (IPA), and significant features were clustered. Protein membrane organization and gene density on chromosomes were analyzed and discussed. The enriched bioinformatics analysis could provide clues and basis to the development of diagnostic markers and therapeutic targets for infertility and male contraception.

An efficient synthesis of 3-halofurans by the intramolecular cyclization of 2-(1-alkynyl)-2-alken-1-ones with cupric halide has been developed. A broad range of 3-chloro- and 3-bromofuran derivatives could be obtained in the present method in moderate to good yields. The 3-halofuran derivatives are potential synthetic intermediates for amplification of molecular complexity.
Prescribed-time Stabilization for a Class of Nonlinear Systems with Control Singularities
Lulu Fu,Ruicheng Ma,Jun Fu 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.2
This paper studies the prescribed-time stabilization of a class of nonlinear systems with control singularities. The settling time is independent of not only the design parameters but also the initial conditions, and can be set according to per our will. By using backstepping, we simultaneously construct a control Lyapunov function (CLF) with singularity and a control law to prescribed-time stabilize the equilibrium point of the studied system in settling time, and avoid all trajectories from crossing the control singularity set. Further, the feasibility region is consistent with the attraction region, and the attraction region is also maximized. That is, the positive invariance condition is achieved. Finally, two examples are presented to illustrate the effectiveness of our proposed method.
Effect of Ginger Extract and Citric Acid on the Tenderness of Duck Breast Muscles

The objective of this study was to examine the effect of ginger extract (GE) combined with citric acid on the tenderness of duck breast muscles. Total six marinades were prepared with the combination of citric acid (0 and 0.3 M citric acid) and GE (0, 15, and 30%). Each marinade was sprayed on the surface of duck breasts (15 mL/100 g), and the samples were marinated for 72 h at 4℃. The pH and proteolytic activity of marinades were determined. After 72 h of marination, Warner Bratzler shear force (WBSF), myofibrillar fragmentation index (MFI), pH, cooking loss, moisture content, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and protein solubility were evaluated. There was no significant (p>0.05) difference in moisture content or cooking loss among all samples. However, GE marination resulted in a significant (p<0.05) decrease in WBSF but a significant (p<0.05) increase in pH and MFI. In addition, total protein and myofibrillar protein solubility of GE-marinated duck breast muscles in both WOC (without citric acid) and WC (with citric acid) conditions were significantly (p<0.05) increased compared to non-GE-marinated duck breast muscles. SDS-PAGE showed an increase of protein degradation (MHC and actin) in WC condition compared to WOC condition. There was a marked actin reduction in GE-treated samples in WC. The tenderization effect of GE combined with citric acid may be attributed to various mechanisms such as increased MFI and myofibrillar protein solubility.
