Background: The renin angiotensin system (RAS) has been proposed as a potential modifier of the development of Alzheimer's disease (AD). However, prospective studies of RAS are sparse especially among cognitively normal individuals with type 2 diabetes mellitus (T2DM) and other vascular risk factors. We aimed to determine whether plasma levels or activity of the RAS marker ACE-1 predicts cognitive decline over an 8-year period in this population.

Understanding the penetration behaviour of pesticide active ingredient (AI) in the presence of adjuvants is important in managing application efficacy and minimizing residues. This study investigates the impact of non-ionic surfactant alkylphenol ethoxylates (APEOs) on the penetration of two pesticides, systemic thiabendazole and non-systemic phosmet, in apple and spinach. Surface-enhanced Raman Spectroscopy (SERS) was employed using two different detection methods, namely XZ depth mapping and XY area mapping, in conjunction with liquid Chromatography with tandem mass spectrometry (LC-MS/MS) to investigate the penetration of various pesticide formulations over time.

Changes in brain mitochondrial metabolism are coincident with functional decline; however, direct links between the two have not been established. Here, we show that mitochondrial targeting via the adiponectin receptor activator AdipoRon (AR) clears neurofibrillary tangles (NFTs) and rescues neuronal tauopathy-associated defects. AR reduced levels of phospho-tau and lowered NFT burden by a mechanism involving the energy-sensing kinase AMPK and the growth-sensing kinase GSK3b.

Background: National Comprehensive Cancer Network guidelines recommend sentinel lymph node biopsy (SLNB) for patients with > 10% risk of positivity, consider SLNB with 5-10% risk, and foregoing with < 5% risk. The integrated 31-gene expression profile (i31-GEP) algorithm combines the 31-GEP with clinicopathologic variables, estimating SLN positivity risk.

Methods: The i31-GEP SLNB risk prediction accuracy was assessed in patients with T1-T2 tumors enrolled in the prospective, multicenter DECIDE study (n = 322).

Triplet excited states in organic semiconductors are usually optically dark and long-lived as they have a spin-forbidden transition to the singlet ground state and therefore hinder processes in light-harvesting applications. Also, triplets often cause damage to the system as they can sensitize the formation of reactive singlet oxygen. Despite these unfavorable characteristics, there exist mechanisms through which we can utilize triplet states, and that constitutes the scope of this review.

Understanding the causes of past atmospheric methane (CH) variability is important for characterizing the relationship between CH, global climate and terrestrial biogeochemical cycling. Ice core records of atmospheric CH contain rapid variations linked to abrupt climate changes of the last glacial period known as Dansgaard-Oeschger (DO) events and Heinrich events (HE). The drivers of these CH variations remain unknown but can be constrained with ice core measurements of the stable isotopic composition of atmospheric CH, which is sensitive to the strength of different isotopically distinguishable emission categories (microbial, pyrogenic and geologic).

Background: Nurses perform frequent heart rate (HR) and blood pressure (BP) monitoring, a widespread and longstanding practice, after cardiac catheterization (CC) to identify vascular access site complications for femoral and radial arterial approach in adult patients.

Objective: The objective of this scoping review was to answer two questions: (1) how does the available evidence support frequent HR and BP monitoring after CC via femoral and radial approach in adult patients and (2) how does this practice prompt bedside nurses in identifying the procedure's major vascular access site complications, including bleeding, hematoma, and pseudoanurysm?

Method: Following the scoping review approach, literature search was conducted (PubMed, CINAHL, Google Scholar) by two co-authors and medical librarian. We reviewed, evaluated, and analyzed the evidence from twenty articles.
