Patient‐Level Barriers and Facilitators to Inpatient Physical Therapy in Adolescents and Young Adults With a Hematological Malignancy: A Qualitative Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite their increased risk for functional impairment resulting from cancer and its treatments, few adolescents and young adults (AYAs) with a hematological malignancy receive the recommended or therapeutic dose of exercise per week during inpatient hospitalizations.

Comparison of cavitation erosion of NiCrBSi and AISI 316L coatings deposited by powder plasma transferred Arc welding

Acta Polytechnica
This study carefully compares the effect of microstructure and hardness on the cavitation wear resistance of PPTA (Powder Plasma Transferred Arc) deposited coatings. Deposits were made on a substrate of S235JR structural steel.

Mechanical characterisation of water-jet shot peened H13 tool steel surface

Journal of Mechanical Engineering and Sciences, 2022
A wear-resistant surface is achievable via the surface treatment of various sources such as laser, water-jet, ion beam, and plasma. This paper investigates the parameters of water-jet shot-peened H13 tool steel for minimum surface roughness and maximum ...

The Effect of Heat Treatment on Mechanical Properties of Cu-0.93 mass％Ni-0.24 mass％P Alloy [PDF]

, 2019
Cu-Ni-P alloys are the typical precipitation-hardening material. Thus, Cu-Ni-P alloys are expected to apply alternative materials for heat-exchanger tubes.

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Improved Hardness of Approximating Chromatic Number [PDF]

, 2013
We prove that for sufficiently large K, it is NP-hard to color K-colorable graphs with less than 2^{K^{1/3}} colors. This improves the previous result of K versus K^{O(log K)} in Khot [14]

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.
