Compound eyes of insects and crustaceans： Some examples that show there is still a lot of work left to be done

引用

Insect Science 2015年第3期22卷 461-481页

作者： victor Benno Meyer-Rochow Department of Biology University of Oulu P.O. Box 3000 FIN-90014 Oulu Finland

Similarities and differences between the 2 main kinds of compound eye （apposition and superposition） are briefly explained before several promising topics for research on compound eyes are being introduced. Research on the embryology and molecular control of the development of the insect clear-zone eye with superposition optics is one of the suggestions, because almost all of the developmental work on insect eyes in the past has focused on eyes with apposition optics. Age- and habitat-related ultrastructural studies of the retinal organization are another suggestion and the deer cad Lipoptena cervi, which has an aerial phase during which it is winged followed by a several months long parasitic phase during which it is wingless, is mentioned as a candidate species. Sexual dimorphism expressing itself in many species as a difference in eye structure and function provides another promising field for compound eye researchers and so is a focus on compound eye miniaturization in very small insects, especially those that are aquatic and belong to species, in which clear-zone eyes are diagnostic or are tiny insects that are not aquatic, but belong to taxa like the Diptera for instance, in which open rather than closed rhabdoms are the rule. Structures like interommatidial hairs and glands as well as corneal microridges are yet another field that could yield interesting results and in the past has received insufficient consideration. Finally, the dearth of information on distance vision and depth perception is mentioned and a plea is made to examine the photic environment inside the foam shelters of spittle bugs, chrysales of pupae and other structures shielding insects and crustaceans.

Fine structural description of the compound eye of the Madagascar ＇hissing cockroach＇ Gromphadorhinaportentosa （Dictyoptera： Blaberidae）

引用

Insect Science 2008年第2期15卷 179-192页

作者： Monalisa Mishra victor Benno Meyer-Rochow Faculty of Engineering and Sciences Jacobs University (formerly known as International University Bremen) Bremen Germany Department of Biology (Elainmuseo) University of Oulu Oulu Finland

The compound eyes of the wingless adults of the Madagascar ＇hissing cockroach＇ Gromphadorhinaportentosa Sachum, 1853 were examined by light and electron microscopy. Each eye contains 2 400-2 500 mostly hexagonal facets. However, irregularities affecting both shape and size of the ommatidia are relatively common, especially towards the margins of the eye. An individual ommatidium of this eucone type of apposition eye contains eight retinula cells, which give rise to a centrally-fused, tiered rhabdom. The distal end of the latter is funnel-shaped and accommodates the proximal end of the cone in its midst, Further below, the rhabdom （then formed by the rhabdomeres of four retinula cells） assumes a squarish profile with microvilli aligned in two directions at right-angle to each other. Cross sections through the proximal regions of the rhabdom display triangular rhabdom outlines and microvilli （belonging to 3-4 retinula cells different from those involved in the squarish more distal rhabdom） that run in three directions inclined to one another by 120°. Overall the organization of the eye conforms to the orthopteroid pattern and particularly closely resembles that of the American cockroach Periplaneta americana. However, since G. portentosa possesses fewer ommatidia, this could be a consequence of its inability to fly. On the other hand, the large size of the facets and the voluminous rhabdoms suggest considerable absolute sensitivity and an ability to detect the plane of linearly polarized light. Based on the pattern of microvillus orientations in combination with the crepuscular lifestyle G. portentosa leads and the habitat it occurs in, the prediction is made that this insect uses its green receptors for e-vector discrimination in the environment of down-welling light that reaches the forest floor.

Wrapping up the role of pericytes in Parkinson's disease

Neural Regeneration Research 2023年第11期18卷 2395-2396页

作者： Taylor John Stevenson Birger victor Dieriks Department of Pharmacology University of AucklandAucklandNew Zealand Centre for Brain Research University of AucklandAucklandNew Zealand Department of Anatomy and Medical Imaging University of AucklandAucklandNew Zealand

Pericytes are classically defined as contra ctile cells within the central nervous system that regulate blood flow and permeability of the blood-brain barrier(BBB).This one-sided view is gradually changing,and pericytes are now considered versatile cells that can switch their function in response to different stimuli(Uemura et al.,2020).In addition to their role as gatekeepers of the BBB and maintaining homeostasis of the brain’s microenvironment through adj usting the vascular intraluminal dia meter,pericytes are both sensors and initiators of inflammation.

针对空天地一体化网络信息物理系统模型复杂、很难获得网络拓扑先验知识和模型化假设的特点,研究其基于深度强化学习的垂直切换策略。首先,综合考虑系统稳定性、切换开销和网络使用成本约束,将垂直切换策略问题建模为约束马尔可夫决策过程(CMDP),并给出保证可行解存在的充分条件;其次,提出约束-近端策略优化(CPPO)算法解决该问题,并在基站侧引入分布式强化学习机制加速训练收敛。相较于基准策略,仿真验证了所提垂直切换策略的优越性和有效性。

CD74 in antigen presentation,inflammation,and cancers of the gastrointestinal tract

引用

World Journal of Gastroenterology 2009年第23期15卷 2855-2861页

作者： Ellen J Beswick victor E Reyes Department of Pediatrics University of Texas Medical Branch Galveston TX 77555 United States Department of Pediatrics and Microbiology and Immunology University of Texas Medical Branch Galveston TX 77555 United States

CD74 is a protein whose initial role in antigen presentation was recognized two decades ago. Recent studies have revealed that it has additional functions as a receptor for macrophage migration inhibitory factor and as a receptor for an important human pathogen, Helicobacter pylori （H pylon）. The role of CD74 as a receptor is important because after binding of migration inhibitory factor or H pylori, NF-κB and Erkl/2 activation occurs, along with the induction of proinflammatory cytokine secretion. This review provides an up-to-date account of the functions of CD74 and how it might be involved in inflammation and cancer within the gastrointestinal tract.
