Treatment pattern among patients with relapsed/refractory multiple myeloma (RRMM) who had received pomalidomide-based regimens in Taiwan.

Background/purpose: The treatment landscape of relapsed/refractory multiple myeloma (RRMM) is rapidly evolving in Taiwan. The present study aimed to assess the treatment patterns among RRMM patients in Taiwan.

Methods: This retrospective, chart review-based, non-interventional study collected data on RRMM patients (≥20 years old) receiving pomalidomide-based treatment between January 2017 and December 2020 across five sites in Taiwan.

Effect of surface inclination on vertical loading rate and footstrike pattern in trail and road runners.

Trail runners have been reported to be more injury prone than road runners. Limited past studies have examined the difference in the running biomechanics between the two groups of runners. More importantly, the effect of surface inclination has not been fully investigated.

Synthesis of unsymmetrical 1,3-diynes via alkyne cross-metathesis.

The tungsten benzylidyne complex [PhC≡W{OSi(OtBu)3}3] (1) efficiently catalyses the metathetic conversion between symmetrical and unsymmetrical 1,3-diynes, which provides the opportunity to prepare the latter species directly from terminal alkynes by a combination of copper-catalysed homocoupling and catalytic alkyne cross-metathesis (ACM).

[Antitumor effect of calcium phosphate cement incorporating doxorubicin microspheres].

Objective: To investigate the antitumor effect of calcium phosphate cement incorporated with doxorubicin microspheres.

Methods: The absorbance at 490 nm of SaoS-2 cells cultured for 5 days in the media containing the extract of the cement incorporating doxorubicin microspheres was measured using Cell Counting Kit-8. SaoS-2 cells were adjusted to the density of 2x10(7) ml(-1) and injected into the left buttock of nude mouse in the volume of 0.
