Psychosurgery in the History of Stereotactic Functional Neurosurgery
The paper invites to reappraise the role of psychosurgery for and within the development of functional stereotactic neurosurgery. It highlights the significant and long-lived role of stereotactic neurosurgery in the treatment of severe and chronic mental disorders. Stereotactic neurosurgery developed out of psychosurgery. It was leucotomy for psychiatric disorders and chronic pain that paved the way for stereotactic dorsomedial thalamotomy in these indications and subsequently for stereotactic surgery...

Huisgen's 1,3‐Dipolar Cycloadditions to Fulvenes Proceed via Ambimodal [6+4]/[4+2] Transition States
Ring, ring : Computational studies with density functional theory (DFT) of Huisgen's 1,3‐dipolar cycloadditions and variants subsequently developed by others show that they involve ambimodal [6+4]/[4+2] transition states. Intriguingly, the ambimodal transition state with the nitrile ylide gives both products, favoring the [6+4] adduct, as found experimentally, while the diazomethane reaction is predicted to give only the [4+2] adduct. Abstract Huisgen's 1960 announcement of the concept...

Toward artificial mussel‐glue proteins: Differentiating sequence modules for adhesion and switchable cohesion
The synthesis of artificial mussel‐glue proteins with pH triggered cohesion control mechanism is described by extending the tyrosinase activated polymerization of peptides to sequences having specific modules for cohesion control. The high propensity of those sequence sections to adapt β‐sheets is temporarily suppressed by switch defects. This allows enzymatic activation and polymerization to proceed undisturbed. The β‐sheet formation is regained after polymerization by changing pH from 5.5 to 6.8,...

Activation of the G‐Protein‐Coupled Receptor Rhodopsin by Water
Visual rhodopsin is an important archetype for G‐protein–coupled receptors, which are membrane proteins implicated in cellular signal transduction.  Here we show experimentally for the first time that ~80 water molecules flood rhodopsin upon light absorption to form a solvent‐swollen active state.  An influx of mobile water is sufficient for activating the photoreceptor, and is supported by molecular dynamics (MD) simulations. Combined force‐based measurements involving osmotic and hydrostatic pressure...

Water oxidation with cobalt‐loaded linear conjugated polymer photocatalysts
We report here the first examples of linear conjugated organic polymer photocatalysts that produce oxygen from water after loading with cobalt and in the presence of an electron scavenger. The oxygen evolution rates, which are higher than for related organic materials, can be rationalized by a combination of the thermodynamic driving force for water oxidation, the light absorption of the polymer, and the aqueous dispersibility of the relatively hydrophilic polymer particles. We also used transient...

Modulation of H‐reflex responses and frequency‐dependent depression by repetitive spinal electromagnetic stimulation: from rats to humans and back to chronic spinal cord injured rats
Abstract The lack of propagation of signals through survived fibers is among the major reasons for functional loss after incomplete spinal cord injury (SCI). Our recent results of animal studies demonstrate that spinal electromagnetic stimulation (SEMS) can enhance transmission in damaged spinal cord and this type of modulation depends on the function of NMDA receptors at the neuronal networks below the injury level. Here, our pilot human study revealed that administration of repetitive SEMS induced...
