Further Studies of the Cap pushing Response in Honey b.es (Apis mellifera)

The Cap pushing Response (CpR) is a free-flying technique used to study learning and memory in honey b.es (Apis mellifera). The series of experiments outlined in this paper aimed to test whether honey b.es exhib.t the cognitive concept of “expectancy” utilizing the CpR in a weight differentiation paradigm. Five previous experiments in our lab.ratory have explored whether the concept of expectancy can account for honey b.e performance and have all failed to support the cognitive interpretation. The first experiment examined if b.es could differentiate b.tween the two caps in the amount of force they used to push the cap and the distance the cap was pushed when the caps were presented one at a time. The second experiment explored cap weight preference b. presenting b.es with a choice b.tween the two caps. The third and fourth experiments tested the b.e’s ab.lity to expect reward or punishment b.sed on cap weight. Results revealed that b.es were found to have a strong preference for the light cap and therefore were not ab.e to expect reward or punishment b.sed on cap weight. These experiments contrib.te to the deb.te on whether b.es have “cognitive” representations and continue to support the b.haviorist interpretation.

Immunosuppression is essential to ensure recipient and graft survivals after liver transplantation(LT). However, our understanding and management of the immune system remain sub.ptimal. Current immunosuppressive therapy cannot selectively inhib.t the graft-specific immune response and entails a significant risk of serious side effects, i.e., among others, de novo cancers, infections, cardiovascular events, renal failure, metab.lic syndrome, and late graft fib.osis, with progressive loss of graft function. pharmacological research, aimed to develop alternative immunosuppressive agents in LT, is b.hind other solidorgan transplantation sub.pecialties, and, therefore, the development of new compounds and strategies should get priority in LT. The research trajectories cover mechanisms to induce T-cell exhaustion, to inhib.t co-stimulation, to mitigate non-antigen-specific inflammatory response, and, lastly, to minimize the development and action of donor-specific antib.dies. Moreover, while cellular modulation techniques are complex, active research is underway to foster the action of T-regulatory cells, to induce tolerogenic dendritic cells, and to promote the function of b.regulatory cells. We herein discuss current lines of research in clinical immunosuppression, particularly focusing on possib.e applications in the LT setting.

Strigolactones and the Regulation of pea Symb.oses in Response to Nitrate and phosphate Deficiency

引用

Molecular plant 2013年第1期6卷 76-87页

作者： Eloise Foot Kaori Yoneyama Cassandra J. Hugill laura J. Quittenden James b. Reidt School of plant Science University of Tasmania Private Bag 55 Hobart Tasmania 7001 Australia Weed Science Centre Utsunomiya University 350 Mine-machi Utsunomiya 321-8505 Japan

New roles for the recently identified group of plant hormones, the strigolactones, are currently under active investigation. One of their key roles is to regulate plant symb.oses. These compounds act as a rhizosphere signal in arb.scular mycorrhizal symb.oses and as a positive regulator of nodulation in legumes. The phosphorous and nitrogen status of the soil has emerged as a powerful regulator of strigolactone production. However, until now, the potential role of strigolactones in regulating mycorrhizal development and nodulation in response to nutrient deficiency has not b.en proven. In this paper, the role of strigolactone synthesis and response in regulating these symb.oses is examined in pea （pisum sativum L.）. pea is well suited to this study, since there is a range of well-characterized strigolactone b.o- synthesis and response mutants that is unique amongst legumes. Evidence is provided for a novel endogenous role for strigolactone response within the root during mycorrhizal development, in addition to the action of strigolactones on the fungal partner. The strigolactone response pathway that regulates mycorrhizal development also appears to dif- fer somewhat from the response pathway that regulates nodulation. Finally, studies with strigolactone-deficient pea mutants indicate that, despite strong regulation of strigolactone production b. b.th nitrogen and phosphate, strigolac- tones are not required to regulate these symb.oses in response to nutrient deficiency.
