Abstract:

Asymmetrical sinusoidal whole-body rotation sequences with half-cycles at different velocities induce self-motion misperception. This is due to an adaptive process of the vestibular system that progressively reduces the perception of slow motion and increases that of fast motion. It was found that perceptual responses were conditioned by four previous cycles of asymmetric rotation in the dark, as the perception of self-motion during slow and fast rotations remained altered for several minutes. Surprisingly, this conditioned misperception remained even when asymmetric stimulation was performed in the light, a state in which vision completely cancels out the perceptual error. This suggests that vision is unable to cancel the misadaptation in the vestibular system but corrects it downstream in the central perceptual processing. Interestingly, the internal vestibular perceptual misperception can be cancelled by a sequence of asymmetric rotations with fast/slow half-cycles in a direction opposite to that of the conditioning asymmetric rotations.

Full text

Abstract:

Lipid asymmetry, the difference in the lipid composition in the inner and outer lipid monolayers (leaflets) of a membrane, is an important feature of eukaryotic plasma membranes. Investigation of the biophysical consequences of lipid asymmetry has been aided by advances in the ability to prepare artificial asymmetric membranes, especially by use of cyclodextrin-catalyzed lipid exchange. This review summarizes recent studies with artificial asymmetric membranes which have identified conditions in which asymmetry can induce or suppress the ability of membranes to form ordered domains (rafts). A consequence of the latter effect is that, under some conditions, a loss of asymmetry can induce ordered domain formation. An analogous study in plasma membrane vesicles has demonstrated that asymmetry can also suppress domain formation in natural membranes. Thus, it is possible that a loss of asymmetry can induce domain formation in vivo.

Full text

Abstract:

The cycloaddition of α-hydroxy orthoquinodimethane, generated photochemically from 2-methylbenzaldehyde, to the fumarate and acrylate of S-methyl lactate has been found to give a single diastereomer with high asymmetric induction (>95% de). This reaction provides a new and versatile synthetic route to substituted tetralins of high optical purity. A trans stereochemistry between the vicinal hydroxyl and carboxylactyl groups has been established for these cycloadducts. This is in contrast to previous work where cis stereochemistry has always been found for major cycloadducts of α-hydroxy o-QDMs. The high asymmetric induction, unusual diastereoselectivity, and the potential use of these reactions in asymmetric synthesis are discussed. Keywords: o-quinodimethanes, Diels–Alder, asymmetric, cycloaddition, induction, diastereoselective.

Abstract:

Asymmetric cell division can produce daughter cells with different developmental fates and is often accompanied by a difference in cell size. A number of recent genetic and in vivo imaging studies in Drosophilaand Caenorhabditis elegans have begun to elucidate the mechanisms underlying the rearrangements of the cytoskeleton that result in eccentrically positioned cleavage planes. As a result, we are starting to gain an insight into the complex nature of the signals controlling cytoskeletal dynamics in the dividing cell. In this commentary we discuss recent findings on how the mitotic spindle is positioned and on cleavage site induction and place them in the context of cell size asymmetry in different model organisms.

Abstract:

Consistent left-right asymmetry in organ morphogenesis is a fascinating aspect of bilaterian development. Although embryonic patterning of asymmetric viscera, heart, and brain is beginning to be understood, less is known about possible subtle asymmetries present in anatomically identical paired structures. We investigated two important developmental events: physiological controls of eye development and specification of neural crest derivatives, inXenopus laevisembryos. We found that the striking hyperpolarization of transmembrane potential (Vmem) demarcating eye induction usually occurs in the right eye field first. This asymmetry is randomized by perturbing visceral left-right patterning, suggesting that eye asymmetry is linked to mechanisms establishing primary laterality. Bilateral misexpression of a depolarizing channel mRNA affects primarily the right eye, revealing an additional functional asymmetry in the control of eye patterning byVmem. The ATP-sensitive K+channel subunit transcript, SUR1, is asymmetrically expressed in the eye primordia, thus being a good candidate for the observed physiological asymmetries. Such subtle asymmetries are not only seen in the eye: consistent asymmetry was also observed in the migration of differentiated melanocytes on the left and right sides. These data suggest that even anatomically symmetrical structures may possess subtle but consistent laterality and interact with other developmental left-right patterning pathways.

Abstract:

Background: The paper deals with the modelling of a traction Linear Induction Motor (LIM) for public transportation. Typical problems arising from the electromagnetic finite element model development are described. The end effect causes asymmetry of phase impedances of the LIM. Because of that, if the LIM is supplied from the voltage inverter, which is usually the case, the phase currents become asymmetric. This causes performance calculation discrepancies in models that assume phase current symmetry. Aim: The aim of the paper is to develop a method for calculating the imbalanced three-phase LIM currents to precisely predict the LIM performance. Methods: Here, a method is developed to calculate the LIM phase current asymmetry by means of a self-developed electromagnetic finite element program – ELMAG, capable of adapting mesh generation based on Reynolds, Péclet and skin-depth numbers. Results: The calculated asymmetric currents are used in a real size traction LIM calculation in COMSOL, to derive the performance characteristics for comparison with the results achieved when supplying the LLIM with the symmetric three phase current. Conclusion: These results show that the natural asymmetry of the currents is an important factor that must be considered in appropriately calculating the LIM performance.

Abstract:

Attempts to obtain enantiomerically enriched tetrahydrofuran derivatives via an intramolecular oxy-Michael addition reaction of ε-hydroxyenone is discussed. Despite previous difficulties associated with the asymmetric induction of this reaction, which can proceed even without a catalyst, a highly efficient asymmetric induction was realized using a bifunctional organocatalyst derived from a cinchona alkaloid. The reaction could be extended to ζ-hydroxyenone to yield an optically active tetrahydropyran derivative with a high ee. In these reactions, it is important for the gentle acidic and basic sites in the bifunctional organocatalyst to be arranged properly within the molecular skeleton of the catalyst. The high performance asymmetric induction relied on the affinity of the catalyst for the substrate, which played an important role. A disubstituted tetrahydropyran synthesis could be effectively performed via kinetic resolution using ζ-hydroxyenone containing a secondary alcohol moiety using a chiral phosphoric acid catalyst.

Abstract:

The past ten years have seen impressive advances in asymmetric synthesis. This review summarizes the recent advances in a particular set of asymmetric reactions, the reactions of diazo compounds catalyzed by transition metal complexes. Additionally, the emphasis of this summary is on reactions wherein the induction arises from a catalyst or an auxiliary, rather than some inherent asymmetry of the substrate. The covered reactions fall into two reaction types; cyclopropanations and insertions. The cyclopropanation section of this review describes how high stereoselectivities are possible using either chiral auxiliaries or various metal complexes. Both these strategies are effective for producing optically-enriched intermediates; however, the use of catalysts to control the stereochemistry of the cyclopropanation reaction is much more common than the corresponding use of auxiliaries Workers in the asymmetric cyclopropanation field have primarily used Cu(l) and Rh(ll) complexes as catalysts for these reactions, although several complexes of other metals do afford high asymmetric induction. Both inter- and intramolecular cyclopropanations afford synthetically useful selectivities. The insertion section of this review summarizes recent advances in the use of auxiliaries and catalysts for controlling the stereoselectivity of the insertion into various bonds. Insertion into C-H bonds are by far the most intensively studied, although there has been some success with asymmetric insertions into 0-H, S-H, Si-H and C-0 bonds. Complexes of Rh(ll) are almost universally employed for asymmetric insertions. As in the case of cyclopropanations, both inter- and intramolecular insertions can proceed with useful selectivities. Again, catalyst control has proven a more versatile way to control absolute stereochemistry than auxiliary control.
