Successful Treatment of Solitary Bone Metastasis of Non-Small Cell Lung Cancer with Bevacizumab and Hyperthermia

Non-small cell lung cancer (NSCLC) represents 85 % of all malignant lung cancers. In metastatic disease the principle goal of palliative therapy is to prolong survival with least toxicity and best patients’ quality of life. Bevacizumab (BEV) has been approved as first line treatment in combination with platinum based chemotherapy and maintenance therapy in NSCLC. BEV can be added safely to several chemotherapeutic agents, however there is no data on coadministration with thermotherapy. Even in localized disease no robust evidence exists about the beneficial effect of loco-regional thermotherapy on overall survival, but it might be used successfully in symptom palliation. In this article a successful co-administration of BEV and hyperthermia is reported in a patient with monolocalized bone metastasis from previously operated NSCLC. This case suggests that electrohyperthermia can probably be incorporated in palliative therapy added not only to radiotherapy or chemotherapy but also to anti-angiogenic BEV treatment.

Same molecule but different expression: aging and sepsis trigger NLRP3 inflammasome activation,a target of melatonin

The connection between the innate immune system, clock genes, and mitochondrial bioenergetics was analyzed during aging and sepsis in mouse heart. Our results suggest that the sole NF‐κB activation does not explain the inflammatory process underlying aging; the former also triggers the NLRP3 inflammasome that enhances caspase‐1‐dependent maturation of IL‐1β. In this way, aged mice enter into a vicious cycle as IL‐1β further activates the NF‐κB/NLRP3 inflammasome link. The origin of NF‐κB activation was related to the age‐dependent Bmal1/Clock/RORα/Rev‐Erbα loop disruption, which lowers NAD⁺ levels, reducing the SIRT1 deacetylase ability to inactivate NF‐κB. Consequently, NF‐κB binding to DNA increases, raising the formation of proinflammatory mediators and inducing mitochondrial impairment. The cycle is then closed with the subsequent NLRP3 inflammasome activation. This paired contribution of the innate immune pathways serves as a catalyst to magnify the response to sepsis in aged compared with young mice. Melatonin administration blunted the septic response, reducing inflammation and oxidative stress, and enhancing mitochondrial function at the levels of nonseptic aged mice, but it did not counteract the age‐related inflammation. Together, our results suggest that, although with different strengths, chronoinflammaging constitutes the biochemical substrate of aging and sepsis, and identifies the NLRP3 inflammasome as a new molecular target for melatonin, providing a rationale for its use in NLRP3‐dependent diseases.     

Speed-invariant encoding of looming object distance requires power law spike rate adaptation

Neural representations of a moving object’s distance and approach speed are essential for determining appropriate orienting responses, such as those observed in the localization behaviors of the weakly electric fish, Apteronotus leptorhynchus. We demonstrate that a power law form of spike rate adaptation transforms an electroreceptor afferent’s response to “looming” object motion, effectively parsing information about distance and approach speed into distinct measures of the firing rate. Neurons with dynamics characterized by fixed time scales are shown to confound estimates of object distance and speed. Conversely, power law adaptation modifies an electroreceptor afferent’s response according to the time scales present in the stimulus, generating a rate code for looming object distance that is invariant to speed and acceleration. Consequently, estimates of both object distance and approach speed can be uniquely determined from an electroreceptor afferent’s firing rate, a multiplexed neural code operating over the extended time scales associated with behaviorally relevant stimuli.
