This study sheds light on a poorly understood area in insect-plant-microbe interactions,focusing on aphid probing and feeding behavior on plants with varying levels of arbuscular mycorrhizal(AM)fungus root *** investigates a commonly occurring interaction of three species:pea aphid Acyrthosiphon pisum,barrel medic Medicago truncatula,and the AM fungus Rhizophagus irregularis,examining whether aphid-feeding behavior changes when insects feed on plants at different levels of AM fungus colonization(42% and 84% root length colonized).Aphid probing and feeding behavior was monitored throughout 8 h of recording using the electrical penetration graph(EPG)technique,also,foliar nutrient content and plant growth were ***,aphids took longer to reach their 1st sustained phloem ingestion on the 84% AM plants than on the 42% AM plants or on *** aphids showed phloem ingestion on the 84% AM plants relative to the 42% AM *** of the 84% AM plants had higher percent carbon(43.7%)relative to controls(40.5%),and the 84% AM plants had reduced percent nitrogen(5.3%)relative to the 42% AM plants(6%).In conclusion,EPG and foliar nutrient data support the hypothesis that modifications in plant anatomy(e.g.,thicker leaves),and poor food quality(reduced nitrogen)in the 84% AM plants contribute to reduced aphid success in locating phloem and ultimately to differences in phloem sap *** work suggests that *** plants benefit from AM symbiosis not only because of increased nutrient uptake but also because of reduced susceptibility to aphids.

As surgical techniques continue to move towards less invasive techniques,single incision laparoscopic surgery(sILs),a hybrid between traditional multiport laparoscopy and natural orifice transluminal endoscopic surgery,was introduced to further the enhanced outcomes of multiport laparoscopy. The safety and feasibility of sILs for both benign and malignant colorectal disease has been proven. sILs provides the potential for improved cosmesis,postoperative pain,recovery time,and quality of life at the drawback of higher technical skill required. In this article,we review the history,describe the available technology and techniques,and evaluate the benefits and limitations of sILs for colorectal surgery in the published literature.

The effect of baroclinicity on vortex axisymmetrization is examined within a two-layer dynamical *** basic state vortices are constructed with varying degrees of baroclinicity：（i） barotropic,（ii） weak baroclinic,and （iii） strong *** linear and nonlinear evolution of wavenumber-2 baroclinic disturbances are examined in each of the three basic state *** results show that the radial propagating speed of the vortex Rossby wave at the lower level is larger with the stronger baroclinicity,resulting in a faster linear axisymmetrization process in the stronger baroclinic *** is found that the nonlinear axisymmetrization process takes the longest time in the strongest baroclinic vortex among the three different basic vortices due to the weaker kinetic energy transfer from asymmetric to symmetric circulations at the lower level.A major finding in this study is that the same initial asymmetric perturbation can have different effects on symmetric vortices depending on the initial vortex *** numerical weather prediction models,this implies that there exists a sensitivity of the subsequent structural and intensity change solely due to the specification of the initial vertical shear of the tropical cyclone vortex.

The barotropic and baroclinic disturbances axisymmetrized by the barotropic basic vortex are examined in an idealized modeling framework consisting of two *** a Wentzel-Kramers-Brillouin approach,the radial propagation of a baroclinic disturbance is shown to be slower than a barotropic disturbance,resulting in a slower linear axisymmetrization for baroclinic *** slower-propagating baroclinic waves also cause more baroclinic asymmetric kinetic energy to be transferred directly to the barotropic symmetric vortex than from barotropic disturbances,resulting in a faster axisymmetrization process in the nonlinear baroclinic wave case than in the nonlinear barotropic wave case.

1 Approaching East Asian and Intercultural PhilosophyIn contrast to its pre-modern interpretation in the West, still evident in early modern philosophers such as G. W. Leibniz and Christian Wolff, the conception of philosophy in Western modernity has been typically restricted and deformed in ethnocentric and ideological definitions as an intrinsically Western and occidental tradition that contradicts its own ostensibly universal aspirations.1 This questionable understanding of philosophy as a mythical unified self-unfolding transmission from ancient Greece to Western modernity developed in conjunction with the growth of Western colonialism and racial theorizing in the 18th- and 19th-centuries.

Locally advanced non-small cell lung cancer(NsCLC) continues to be a challenging disease to treat. With high rates of both local and distant failures, there is signiicant interest in inding more biologically active chemotherapy regimens that can contribute to reduce both failures. The phase III PROCLAIM trial, recently published in the Journal of Clinical Oncology entitled "PROCLAIM: randomized phase III trial of pemetrexed–cisplatin or etoposide–cisplatin plus thoracic radiation therapy followed by consolidation chemotherapy in locally advanced nonsquamous non-small-cell lung cancer", compared two diferent chemotherapy regimens given concurrently with radiotherapy in patients with stage III non-squamous lung cancer: pemetrexed plus cisplatin versus cisplatin plus etoposide. Both groups received consolidation chemotherapy. After enrolling 598 of planned 600 patients, the study was stopped early due to futility as no diference was seen in the primary end-point of overall survival. since PROCLAIM was designed as a superiority trial, these results suggest that pemetrexed regimens do not ofer a clinical advantage over standard cisplatin plus etoposide. There are some subpopulations who might still beneit from pemetrexed, especially if clinicians are concerned about myelosuppression-related adverse events. Future trials are needed to investigate novel biologic agents and irradiation techniques that can result in more durable local and distant disease control in locally advanced NsCLC.
