Effectiveness of different combinations of phenoxetol and formaldehyde on preservation of histological features in human cadaveric tissues.

Background: Fixation preserves the tissues in a close to the life-like state by preventing its autolysis and putrefaction. Formalin has long been considered the close to ideal fixative for histological studies. With the awareness of occupational hazards, a few researchers have tried phenoxetol as a secondary preservative which offered comparable histological results to that of formalin.

Nutrient based classification of Phyllospora comosa biomasses using machine learning algorithms: Towards sustainable valorisation.

Sustainable seaweed value chains necessitate accurate biomass biochemical characterisation that leads to product development, geographical authentications and quality and sustainability assurances. Underutilised yet abundantly available seaweed species require a thorough investigation of biochemical characteristics prior to their valorisation. Abundantly available Australian seaweed species lack such comprehensive investigations within the global seaweed industrial value chains.

Leveraging nuclear receptor mediated transcriptional signaling for drug discovery: Historical insights and current advances.

Nuclear receptors (NRs) are ligand-activated transcription factors that regulate gene expression in response to physiological signals, such as hormones and other chemical messengers. These receptors either activate or repress the transcription of target genes, which in turn promotes or suppresses physiological processes governing growth, differentiation, and homeostasis. NRs bind to specific DNA sequences and, in response to ligand binding, either promote or hinder the assembly of the transcriptional machinery, thereby influencing gene expression at the transcriptional level.

Central venous pressure as a method of optimising atrio-ventricular delay after cardiac surgery.

Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.

Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.
