3D printing in palliative medicine: systematic review.

Background: Three-dimensional printing (3DP) enables the production of highly customised, cost-efficient devices in a relatively short time, which can be particularly valuable to clinicians treating patients with palliative care intent who are in need of timely and effective solutions in the management of their patients' specific needs, including the relief of distressing symptoms.

Method: Four online databases were searched for articles published by December 2020 that described studies using 3DP in palliative care. The fields of application, and the relevant clinical and technological data were extracted and analysed.

Effects of post-curing duration on the mechanical properties of complex 3D printed geometrical parts.

This study aims to assess the efficacy of post-curing guidance supplied by 3D printing resin manufacturers. Current guidance applies generically to all geometries with the caveat that post-curing should be extended for 'large' or 'complex' geometries but specific guidance is not provided. Two vat-polymerisation 3D printers (Form3B, Figure 4 Standalone) were used to print test models in 6 biocompatible resins (Pro Black, Med White, Med Amber, Biomed Black, Biomed White, Biomed Amber).

Three-Dimensional Printed Devices for Health Care in Response to the Coronavirus Disease 2019: Lessons Learned to Date.

During the first surge of the coronavirus disease 2019 (COVID-19) there was a tremendous global response from three-dimensional (3D) printing communities and individuals to support local health care systems and staff. The responses involved a range of 3D printer users from amateur makers to conglomerate manufacturers creating personal protective equipment (PPE) and other supplies of which there were shortages. These new supply chains resulted from the democratization of 3D printing, open source file sharing, mass production of desktop machines, and the relatively cheap cost of 3D printers.

Differences between Fragaria clones by fourth derivative room temperature spectroscopy of intact leaves.

Clones of Fragaria were characterized by the attenuance (absorption) spectra of their photosynthetic apparatus. This method uses fourth derivative analysis of spectra of intact lamina of detached leaves at room temperature (20-25 C). Twenty-one different species and hybrids of Fragaria were examined.

Photocontrol of petiole elongation in light-grown strawberry plants.

The mode of phytochrome control of elongation growth was studied in fully-green strawberry (Fragaria x Ananassa Duch.) plants. Petiole growth showed two distinct types of response to light.
