Extracellular vesicle surface engineering with integrins (ITGAL & ITGB2) to specifically target ICAM-1-expressing endothelial cells.

Extracellular vesicles (EVs) are taken up by most cells, however specific or preferential cell targeting remains a hurdle. This study aims to develop an EV that targets cells involved in inflammation, specifically those expressing intercellular adhesion molecule-1 (ICAM-1). To target these cells, we overexpress the ICAM-1 binding receptor "lymphocyte function-associated antigen-1" (LFA-1) in HEK293F cells, by sequential transfection of plasmids of the two LFA-1 subunits, ITGAL and ITGB2 (CD11a and CD18).

Lewy body diseases and the gut.

Gastrointestinal (GI) involvement in Lewy body diseases (LBDs) has been observed since the initial descriptions of patients by James Parkinson. Recent experimental and human observational studies raise the possibility that pathogenic alpha-synuclein (⍺-syn) might develop in the GI tract and subsequently spread to susceptible brain regions. The cellular and mechanistic origins of ⍺-syn propagation in disease are under intense investigation.

Allele expression was quantified by haplotypes from long-read data, with 42,900 allele expression events compared.

Toward a biological definition of neuronal and glial synucleinopathies.

Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases-collectively called synucleinopathies-which include Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, we summarize the drawbacks of the current clinical definition of synucleinopathies and outline the rationale for moving toward an earlier, biology-anchored definition of these disorders, with or without the presence of clinical symptoms.

Microstructure evolution during solution annealing of an Al-Zn-Mg-Cu alloy with La additions.

The high-strength 7xxx Al alloys are frequently used due to their excellent properties. To achieve these properties, heat treatment is crucial. In this study, the influence of La on the microstructure evolution of Al-Zn-Mg-Cu alloys during solution annealing, the first step of heat treatment, was investigated.

An artificial insurance framework for a hydrogen-based microgrid to detect the advanced cyberattack model.

Microgrid systems have evolved based on renewable energies including wind, solar, and hydrogen to make the satisfaction of loads far from the main grid more flexible and controllable using both island- and grid-connected modes. Albeit microgrids can gain beneficial results in cost and energy schedules once operating in grid-connected mode, such systems are vulnerable to malicious attacks from the viewpoint of cybersecurity. With this in mind, this paper explores a novel advanced attack model named the false transferred data injection (FTDI) attack aiming to manipulatively alter the power flowing from the microgrid to the upstream grid to raise voltage usability probability.

Practical naloxone communication tips for pharmacists: Lessons learned from the Linguistic Model of Patient Participation in Care.

Background: Opioid overdose is an ongoing public health issue in the rural United States and can be countered by increasing access to the opioid antagonist naloxone. Community pharmacists are well-positioned to offer and dispense naloxone to patients at risk of opioid overdose, but still experience a range of communication barriers. Understanding rural patient communication preferences is essential to prepare pharmacists to discuss naloxone in a patient-centered manner.

Predictors of Mortality in Venoarterial Extracorporeal Membrane Oxygenation Regardless of Early Left Ventricular Unloading: A National Experience.

Objective: The use of an intra-aortic balloon pump (IABP) has been suggested to unload the left ventricle while on venoarterial extracorporeal membrane oxygenation (VA-ECMO) for cardiogenic shock (CS), leading to possibly improved in-hospital mortality. However, the predictors of mortality on dual mechanical circulatory support have not yet been evaluated, especially in real-world clinical settings. Therefore, a case-control study was conducted to determine the rate of all-cause mortality associated with VA-ECMO use regardless of left ventricular (LV) unloading, and with early LV unloading in the setting of CS, and to identify the predictors of mortality associated with VA-ECMO, with concurrent early LV unloading.

Absolute membrane protein abundance of P-glycoprotein, breast cancer resistance protein, and multidrug resistance proteins in term human placenta tissue and commonly used cell systems: Application in physiologically based pharmacokinetic modeling of placental drug disposition.

The placenta acts as a barrier, excluding noxious substances while actively transferring nutrients to the fetus, mediated by various transporters. This study quantified the expression of key placental transporters in term human placenta (n = 5) and BeWo, BeWo b30, and JEG-3 placenta cell lines. Combining these results with pregnancy physiologically based pharmacokinetic (PBPK) modeling, we demonstrate the utility of proteomic analysis for predicting placental drug disposition and fetal exposure.
