Sensing is a critical function of artificial cells; however, this is challenging to realize using bottom-up approaches. Here, we present a protocol for building protocell membranes that sense cues important for redox biochemistry and signaling by combining synthetic phospholipids and natural lipids. We detail procedures for building giant unilamellar vesicles as protocell models that fluoresce in response to the biologically significant redox agents peroxynitrite, hydrogen peroxide, and hydrogen sulfide. For complete details on the use and execution of this protocol, please refer to (i) Gutierrez and Aggarwal et al. as well as (ii) Erguven and Wang et al..

Background: Prenatally transmitted viruses can cause severe damage to the developing brain. There is unexplained variability in prenatal brain injury and postnatal neurodevelopmental outcomes, suggesting disease modifiers. Of note, prenatal Zika infection can cause a spectrum of neurodevelopmental disorders, including congenital Zika syndrome.

Introduction: Acute normovolaemic haemodilution (ANH) is a perioperative blood management technique involving the removal of whole blood and simultaneous infusion of colloids or crystalloids to achieve haemodilution while maintaining normovolaemia. However, its efficacy in reducing the requirement for perioperative allogeneic blood transfusion remains controversial due to inconsistent findings in the literature. An individualised red cell transfusion strategy, guided by the West China Liu's Score, has demonstrated effectiveness in reducing the need for allogeneic red cell transfusion.

Genetics is the second strongest risk factor for Alzheimer's disease (AD) after age. More than 70 loci have been implicated in AD susceptibility so far, and the genetic architecture of AD entails both additive and nonadditive contributions from these loci. To better understand nonadditive impact of single-nucleotide polymorphisms (SNPs) on AD risk, we examined individual, joint, and interacting (SNPxSNP) effects of 139 and 66 SNPs mapped to the BIN1 and MS4A6A AD-associated loci, respectively.

Background: In cerebral amyloid angiopathy, amyloid beta accumulates within the walls of blood vessels and contributes to impaired vascular integrity and function. In this work, we observe that tau protein similarly builds up along blood vessels in Alzheimer's disease brain.
Method: We obtained frozen inferior temporal cortex from the Massachusetts Alzheimer's Disease Research Center from n = 7 neuropathological confirmed Alzheimer's disease donors and n = 6 normal aging controls.
