Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

open access: yesAdvanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Predicting the degree of P saturation of selected Andisols from the Azores (Portugal) by the acidified ammonium oxalate and the Mehlich 3 methods Avaliação do grau de saturação de P nos Andossolos dos Açores (Portugal) pelos métodos do oxalato de amónio e de Mehlich 3

open access: yesRevista de Ciências Agrárias, 2007
Extractable aluminium (Al), iron (Fe), and phosphorus (P) were assessed on twenty eight soil horizons from a representative range of Andisols from the Azores, using the acidified ammonium oxalate method (Alo, Feo and Po) and the Mehlich 3 method (AlM3 ...

Where geology meets pedology: Late Quaternary tephras, loess, and paleosols in the Mamaku Plateau and Lake Rerewhakaaitu areas [PDF]

open access: yes, 2012
On this trip we focus on tephrostratigraphy and soil stratigraphy together with aspects of palaeoenvironmental reconstruction over long and short time-spans.

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

open access: yesAdvanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Postsynaptic Complexin Mediates Constitutive Exocytosis of Nicotinic Acetylcholine Receptor

open access: yesAdvanced Science, EarlyView.
Beyond its established presynaptic role, complexin is identified as a postsynaptic regulator of neurotransmitter receptor trafficking. By promoting constitutive and activity‐dependent exocytosis of nicotinic acetylcholine receptors, complexin controls spontaneous synaptic signaling at the C.

A climo and litho soil-sequence on the Vico volcano (Italy) [PDF]

open access: yes, 1988
A la suite d'une cartographie pédologique détaillée de la majeure partie de l'appareil volcanique de Vico (Italie), une séquence topoclimatique a été définie. Cing profils ont été choisis à des altitudes représentatives des principales zones climatiques.

Endoplasmic Reticulum Geometry Dictates Neuronal Bursting via Calcium Store Refill Rates and Exposes Selective Neuronal Vulnerability

open access: yesAdvanced Science, EarlyView.
The ER's continuous tubular network is maintained by ER‐shaping proteins whose mutation or dysregulation contributes to neurodegenerative diseases. Here, we show that ER morphology sets the speed of Ca2+ store replenishment between firing events. Disrupting ER continuity slows intra‐ER Ca2+ redistribution from extracellular refill (SOCE) sites, driving

Efectos de tratamientos de labranza sobre la resistencia a la penetración de un Andisol Effects of tillage treatments on penetration resistance on an andisol

open access: yesAgronomía Colombiana, 1992
Se evaluó el efecto sobre la resistencia a la penetración de cuatro implementos de labranza (arado de cinceles, arado de discos, rastrillo californiano y arado rotatorio) en un Andisol (Andic-Eutropept) serie Tibaitatá.

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

open access: yesAdvanced Science, EarlyView.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic
