Development of an Active Cerebrovascular Autoregulation Model Using Representation Learning: A Proof of Concept Study With Experimental Data.

Background And Objectives: It remains a challenge to monitor cerebrovascular autoregulation (CA) reliably and dynamically in an intensive care unit. The objective was to build a proof-of-concept active CA model exploiting advances in representation learning and the full complexity of the arterial blood pressure (ABP) and intracranial pressure (ICP) signal and outperform the pressure reactivity index (PRx).

Methods: A porcine cranial window CA data set (n = 20) was used.

Dissociation of Macromolecules in Laser-Heated Droplets Monitored by CD-MS.

Charge detection mass spectrometry (CD-MS) is used to monitor the dissociation of large (300 kDa to 20 MDa) protein complexes in droplets heated with a 10.6 μm CO laser. In this approach, electrospray ionization (ESI) is used to produce charged droplets containing macromolecular complexes.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

TKK130 is a 3-Hydroxy-Propanamidine (HPA) with Potent Antimalarial Activity and a High Barrier to Resistance.

Malaria continues to pose a significant burden on populations in endemic areas and requires innovative treatment options. Here, we report the synthesis and preclinical evaluation of the novel 3-hydroxypropanamidine (HPA) , which shows excellent antiplasmodial activity against drug-sensitive and -resistant strains. Moreover, in various human cell lines, the compound shows no cytotoxicity and excellent parasite selectivity.
