A foundational tear film model structures the tear film into a mucin layer, an aqueous layer, and an outermost lipid layer (TFLL). Primarily secreted by meibomian glands, the complex mixture of diverse lipid classes contributes to TFLL's unique physicochemical properties. Considering these characteristics, functions of TFLL, such as resistance to evaporation and facilitation of thin film creation, have been established or proposed. However, the impact of TFLL on the oxygenation of the cornea, a transparent tissue without blood vessels, has not been mentioned in any published academic paper. The corneal surface's ongoing metabolic processes, coupled with the replenishment of atmospheric gases, establish an oxygen gradient within the tear film. Accordingly, the transition of oxygen molecules from their gaseous form to the liquid phase is essential, happening through the TFLL. This process hinges on the interplay between lipid layer diffusion and solubility, along with interface transfer, which is modulated by alterations to the physical state and lipid composition. In the absence of research on TFLL, this paper proposes to bring this topic to light for the first time, based on existing knowledge on the oxygen permeability of lipid membranes and the evaporation resistance of lipid layers. Investigations also encompass the oxidative stress, arising from disrupted lipid layers, and its adverse repercussions. Encouraging future basic and clinical research is the function of the proposed TFLL, which seeks to open new paths for the diagnosis and treatment of ocular surface disorders.

Guidelines are crucial for constructing both high-quality care and comprehensive care plans. The quality standards for producing guidelines and the subsequent effort are exceptionally stringent. Subsequently, the adoption of more streamlined methods is imperative.
Within the field of psychiatry, guideline developers investigated the advantages and disadvantages of a dynamic updating approach to digitalized guidelines. This perspective is a critical component of the implementation and should be considered.

Feedforward and feedback signals are inextricably linked in facilitating sensory processing throughout the intricate network of cortical areas within the neocortex. The feedback processing mechanism utilizes higher-level representations to offer contextual insights to lower levels, assisting in crucial perceptual functions, including contour integration and figure-ground segmentation. Despite this, our grasp of the circuit and cellular processes mediating feedback effects is restricted. In mice, utilizing long-range all-optical connectivity mapping, we show the spatially organized nature of the feedback connection from the lateromedial higher visual area (LM) to the primary visual cortex (V1). Feedback's suppressive nature is pronounced when source and target are situated within the same visual space. Differently, if the source is located outside the visual alignment of the target, the feedback is relatively beneficial. Data from two-photon calcium imaging of V1 pyramidal neurons demonstrates that facilitating feedback, integrated nonlinearly within apical tuft dendrites, is triggered by retinotopically offset visual stimuli, inducing local dendritic calcium signals signifying regenerative events. Similar branch-specific local calcium signals are induced by two-photon optogenetic activation of LM neurons projecting to identified feedback-recipient spines in V1. Our research demonstrates that neocortical feedback connectivity and nonlinear dendritic integration work in synergy to create a substrate that supports both predictive and cooperative contextual interactions.

A crucial aspect of neuroscience research is the determination of how behavioral actions manifest as neural activity. As we acquire more detailed large-scale neural and behavioral data, the desire to model neural dynamics during adaptive behaviors intensifies, leading to a crucial exploration of neural representations. Furthermore, while neural latent embeddings might reveal the neurological correlates of behaviors, we currently lack non-linear methods capable of explicitly and comprehensively exploiting the interplay between neural and behavioral data to unveil the complex neural underpinnings of actions. We address this gap by introducing a novel encoding method, CEBRA, which leverages both behavioral and neural data in a (supervised) hypothesis-driven or (self-supervised) discovery-driven approach to generate both consistent and high-performing latent spaces. We establish consistency as a metric for identifying meaningful discrepancies, and the deduced latent representations are useful for decoding purposes. Our tool's effectiveness is validated for calcium and electrophysiology datasets, across sensory and motor activities and in a variety of species performing both simple and complex behaviors. Hypothesis testing on single- and multi-session datasets is facilitated by the system, which can also operate without relying on labels. CEBRA's utility lies in its capacity to map spatial relationships, uncover complex kinematic properties, and generate consistent latent spaces from two-photon and Neuropixels data, culminating in the rapid and accurate decoding of natural videos from visual cortex signals.

Life's complexity relies on the indispensable molecule of inorganic phosphate, denoted as Pi. However, the intricate processes of intracellular phosphate metabolism and signaling in animal tissues are still largely unknown. The effect of persistent phosphorus deficiency on the digestive epithelium of Drosophila melanogaster, leading to hyperproliferation, prompted an investigation into the role of the PXo phosphorus transporter, revealing a downregulation as a result of phosphorus starvation. Pi starvation, coupled with PXo deficiency, led to an increase in the proliferation of cells in the midgut. Further immunostaining and ultrastructural investigations confirmed that PXo uniquely identifies and marks non-canonical multilamellar organelles, specifically, PXo bodies. Furthermore, a Pi imaging technique employing Forster resonance energy transfer (FRET)-based Pi sensor2 revealed that PXo acts to limit cytosolic Pi levels. PXo biogenesis within bodies requires PXo, and Pi deficiency initiates the process of degradation. Proteomic and lipidomic analyses of Pxo bodies highlight their exceptional role as an intracellular phosphate storage site. Thus, the reduction in Pi availability leads to a drop in PXo synthesis and its breakdown throughout the body, a compensatory strategy to elevate cytosolic phosphate.
