תקציר Show full text abstract about The vestibular system detects self-motion and in turn genera...» The vestibular system detects self-motion and in turn generates reflexes that are crucial for our daily activities, such as stabilizing the visual axis (gaze) and maintaining head and body posture. In addition, the vestibular system provides us with our subjective sense of movement and orientation in space. The loss vestibular function due to aging, injury, or disease produces dizziness, postural imbalance, and an increased risk of falls – all symptoms that profoundly impair quality of life.
In this talk, I will describe how the brain processes vestibular information in natural conditions. Notably, our work has established how early stages of processing encode vestibular stimuli and integrate them with extra-vestibular cues – for example proprioceptive and premotor information to ensure accurate perception and behaviour. Our experiments have revealed that while vestibular afferents respond identically to externally-generated and actively-generated self-motion, this is not the case at first central stage of sensory processing. Neurons mediating the vestibulo-spinal reflexes, as well as ascending thalamocortical pathways, are robustly activated during externally-generated motion, however their sensory response are cancelled during actively-generated movements. Our work has further revealed that this cancellation of actively-generated vestibular input occurs only in conditions where the actual sensory signal matches the brain’s internal estimate of the expected sensory consequences of active movement. Moreover, when unexpected vestibular inputs becomes persistent during voluntary motion, a cerebellar-based cancellation mechanism is rapidly updated to re-enable the vital distinction between self-generated and externally-applied stimulation to ensure the maintenance of posture and stable perception. In contrast, vestibular pathways mediating the vestibulo-ocular reflex, employ a different strategy. In this pathway, head velocity is robustly encoded whenever the goal is to stabilize gaze, but when the goal is to voluntarily redirect gaze an efferent copy of the gaze command suppresses the efficacy of this reflex pathway. Taken together, these findings have important implications for understanding the neural basis of perception and action during self-motion.

However, clarification of the exact functional roles of the proteins is still at its infancy. It is obvious that none of these proteins serves only the role initially known for it. Pseudokinase Mixed Lineage Kinase Domain-Like (MLKL) by proinflammatory ligands such as TNF triggers necroptosis, programmed cell death in which rupture of cellular membranes yields release of components that are potentially pro-inflammatory, occurs upon phosphorylation of MLKL by RIPK3. We report that MLKL also controls transport of endocytosed proteins, thereby enhancing degradation of receptors and ligands, modulating their induced signaling, and facilitating generation of extracellular vesicles. This role is exerted on two quantitative levels: a constitutive one independent of RIPK3, and an enhancement triggered by RIPK3. RIPK3 activation induces, prior to any sign of death, association of MLKL with ESCRT proteins and the flotillins, and exclusion of phospho-MLKL from cells within vesicles in association with these proteins. We suggest that release of phosphorylated MLKL within extracellular vesicles serves as a mechanism for self-restricting the necroptotic activity of this protein.

Polyamines are essential polycations present in all living cells. Polyamine levels are maintained from the diet and de-novo synthesis, and their decline with age is associated with various pathologies. Here we found that polyamine levels oscillate in a daily manner. Both clock- and feeding-dependent mechanisms regulate the daily accumulation of key enzymes in polyamine biosynthesis through rhythmic binding of BMAL1:CLOCK to conserved DNA elements. In turn, polyamines control the circadian period in cultured cells and animals by regulating the interaction between the core clock repressors PER2 and CRY1. Importantly, we show that the decline in polyamine levels with age in mice is associated with a longer circadian period that can be reversed upon polyamine supplementation in the diet. Our findings suggest a cross talk between circadian clocks and polyamines biosynthesis that participate in circadian control, and open new possibilities for nutritional interventions against the decay in clock’s function with age.
Highlights
• Diurnal regulation of polyamine biosynthesis by circadian clock and feeding.
• Polyamine levels regulate the circadian period in cultured cells and mice.
• Polyamines modulate the interaction between the core clock proteins PER2 and CRY1.
• Lengthening of the circadian period with age can be reversed by polyamines.

Multi-angle light scattering (MALS) is a first-principles technique for determining the molar mass and size of macromolecules and nanoparticles in solution, independently of conformation. In combination with SEC, MALS overcomes these obstacles to characterize the biophysical properties of proteins and other biomolecules, including molecular weight, size, native oligomeric state, dynamic equilibria and degradation products.
This seminar will present the failure modes of analytical SEC, fundamentals of SEC-MALS and examples of applications to a variety of proteins including IgG, insulin, glycoproteins, membrane proteins and protein complexes as well as viruses and virus-like particles. It will touch on the importance of protein quality control for reproducible science and provide a glimpse into how MALS can analyze complicated protein-protein interactions.

However, failure in essentially all real materials is initiated at a heterogeneity (weak spot), which might be at the largest flaw. Thus, a solid with some scratches will generally fracture at the largest one. As a result, a homogeneous electrode model normally cannot, by its very nature, predict cell failure unless it includes adjustable parameters.
In this talk I will review some evidence for the presence and possible importance of heterogeneities in battery electrodes. I will propose that in some cases the critical electrode flaws are relatively rare and statistically distributed through a collection of nominally identical battery samples. Under these conditions there will be two important consequences that are only rarely addressed or even recognized in the academic battery literature:
(1) Failure lifetime may have a wide distribution. For example, my cell phone battery lasts only 18 months; yours lasts 2½ years. In that case, characterizing battery life by a single number may not be very useful.
(2) Degradation may not be uniformly spatially distributed across a pouch cell. This can lead to a misdiagnosis of the problem. For example, if most of the degradation in a pouch cell takes place at the edges, then there may be leaks there. Trying to improve the electrode material would then be attacking the wrong problem.
I will provide evidence for (1) and (2) and discuss why thinking about these factors might be useful for producing longer-lived commercial batteries.

Graphene is the ultimate two-dimensional material consisting of a single layer of sp2 hybridized carbon. Here we explore different approaches to synthesize this carbon allotrope, ranging from chemical conversion to vapor phase deposition. Briefly, graphite can be converted into graphene oxide (GO) sheets, which readily disperse in water, and then can be reduced by various methods.1-2 Due to its unique ability to be solution processed and patterned, GO and chemically converted graphene hold promise for applications ranging from sensors to transparent conducting electrodes.3-4 Chemical vapor deposition onto metal substrates enables the growth of continuous, large-area graphene (Fig. 1). The challenges of growing graphene, controlling the number of layers, transferring graphene and some exciting uses such as laser scribed graphene for supercapacitors will be discussed.5-6
Fig. Large-area single layer graphene transferred onto a silicon substrate with a 300 nm oxide can be seen with the naked eye, while STM imaging enables seeing the honeycomb network of carbon that makes this material so robust.
