Intestinal IR increases NO and ONOO(-) production in the lung, which may be involved in intestinal IR-mediated lung injury.

Alzheimer’s disease (AD) is characterized by chronic progressive cognitive deterioration frequently accompanied by psychopathological symptoms, including changes in personality and social isolation, which severely reduce quality of life. Currently, no viable therapies or present-day drugs developed for the treatment of AD symptoms are able to slow or reverse AD progression or prevent the advance of neurodegeneration. As such, non-drug alternatives are currently being tested, including deep brain stimulation (DBS). DBS is an established therapy for several neurological and psychiatric indications, such as movement disorders. Studies assessing DBS for other disorders have also found improvements in cognitive function, providing the impetus for clinical trials on DBS for AD. Targets of DBS in AD clinical trials and animal model studies include the fornix, entorhinal cortex (EC), nucleus basalis of Meynert (NBM), and vertical limb of diagonal band (VDB). However, there is still no comprehensive theory explaining the effects of DBS on AD symptoms or a consensus on which targets provide optimal benefits. This article reviews the anatomy of memory circuits related to AD, as well as studies on DBS rescue of AD in these circuits and the possible therapeutic mechanisms.

Neuronal degeneration linked to apoptosis can be inhibited by a family of proteins known as inhibitors of apoptosis proteins (IAPs). We examined three members of the IAP family that are implicated in the regulation of neuronal death. We assessed NAIP, XIAP, and cIAP-2 protein levels in the entorhinal cortex of non-demented, cognitively impaired and Alzheimer's disease cases. Levels of paired helical filament-1 (PHF-1), a marker of neurofibrillary tangles, were assessed to determine their relationship to IAP levels. NAIP was decreased in AD cases compared to mildly impaired and unimpaired cases, and this decrease was associated with increased PHF-1 levels. Low NAIP levels were associated with higher Braak and Braak tangle stage and cognitive dysfunction. XIAP levels were higher in AD cases and cIAP-2 levels did not vary with clinical status. Our data suggest that decreased NAIP may place neurons at risk for the development of tangles and apoptosis.

Efficient regulation of thermal radiation is an effective way to conserve energy consumption of buildings. Because windows are the least energy-efficient part of buildings, their thermal radiation regulation is highly demanded, especially in the changing environment, but is still a challenge. Here, by employing a kirigami structure, we design a variable-angle thermal reflector as a transparent envelope of windows for their thermal radiation modulation. The envelope can be easily switched between heating and cooling modes by loading different pre-stresses, which endow the envelope windows with the ability of temperature regulation, and the interior temperature of a building model can be reduced by ~3.3 °C under cooling mode and increased by ~3.9 °C under heating mode in the outdoor test. The improved thermal management of windows by the adaptive envelope provides an extra heating, ventilation, and air-conditioning energy savings percentage of 13% to 29% per year for buildings located in different climate zones around the world, making the kirigami envelope windows a promising way for energy-saving utilization.

Currently, city complex building forms are too similar with the lack of thematic characteristics, especially the architectural space matching with Lingnan culture design. City commercial space to generate new changes to stimulate the use of geographical and cultural resonance should not only meet the people's inner needs, but also commercial needs, combined with the urban cultural, geographical, consumer psychology and other factors in order to promote Lingnan culture image in the urban commercial complex space.
