A Theoretical Comparative Study of CO2 Cascade Refrigeration Systems
Applied Sciences, 2019 The objective of this work is the comparison of the different cascade refrigeration systems with CO2 in the low-temperature circuit. A total of 18 different cascade refrigeration systems are examined including the CO2/CO2 cascade system.

Intranuclear cascade models lack dynamic flow [PDF]
, 2006 We study the recent claim that the intranuclear cascade model exhibits collective sidewards flow. 4000 intranuclear cascade simulations of the reaction Nb(400 MeV/nucleon)+Nb are performed employing bound and unbound versions of the Cugnon cascade.

Electromagnetic Cascade in the Early Universe and its Application to the Big-Bang Nucleosynthesis
, 1994 We investigate the electromagnetic cascade initiated by injection of very high energy photons in the early Universe and calculate the cascade spectrum by solving a set of Boltzmann equations numerically.

Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Prevalence of polypharmacy: Comparing the status of Indian states
Indian Journal of Community and Family Medicine, 2019 Introduction: The word “poly” is Greek and means many or much. However, the term polypharmacy has been given definitions connected both to the use of more than a certain number of drugs concomitantly and to the clinical appropriateness of drug use ...

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Global polycrisis: the causal mechanisms of crisis entanglement
Global SustainabilityMultiple global crises – including the pandemic, climate change, and Russia's war on Ukraine – have recently linked together in ways that are significant in scope, devastating in effect, but poorly understood.
