Recent advances in chemical synthesis have created new methodologies for synthesizing sequence-controlled synthetic polymers, but rational design of monomer sequence for desired properties remains challenging. In this work, we synthesize periodic polymers with repetitive segments using a sequence-controlled ring-opening metathesis polymerization (ROMP) method, which draws inspiration from proteins containing repetitive sequence motifs. The repetitive segment architecture is shown to dramatically affect the self-assembly behavior of these materials. Our results show that polymers with identical repetitive sequences assemble into uniform spherical nanoparticles after thermal annealing, whereas copolymers with random placement of segments with different sequences exhibit disordered assemblies without a well-defined morphology. Overall, these results bring a new understanding to the role of periodic repetitive sequences in polymer assembly.

Objective: The present study aimed to preliminarily explore the temporal summation (TS) response to repetitive mechanical stimulation in patients with temporomandibular joint disorders (TMD).
Patients And Methods: Twenty patients with unilateral pain in the TMJ and 20 gender- and age-matched healthy controls were included. A modified Quantitative Sensory Testing (QST) protocol was performed including pressure pain thresholds (PPT), mechanical pain thresholds (MPT), and numerical rating scale (NRS) scores of TS effects of 10 repeated 0.

Background: Cervical derangement syndrome (CDS), a form of mechanical neck pain, arises from poor posture, repetitive stress, and segmental dysfunction, resulting in discomfort, restricted cervical mobility, and reduced functional capacity. The study focuses on changes associated with CDS, particularly range of motion (ROM), pain, and functional disability. The study aims to find the effect of kinetic control training (KCT) and the McKenzie approach on CDS.

Rumination is known to have a negative impact on both the process of psychotherapy as well as the development of depressive symptoms and even the probability of relapses in Major Depressive Disorder (MDD). Therefore, treatment approaches focusing on strategies to overcome rumination have been developed over the last decades, e.g.

Segment anything models (SAMs) are gaining attention for their zero-shot generalization capability in segmenting objects of unseen classes and in unseen domains when properly prompted. Interactivity is a key strength of SAMs, allowing users to iteratively provide prompts that specify objects of interest to refine outputs. However, to realize the interactive use of SAMs for 3D medical imaging tasks, rapid inference times are necessary.

Background: Short-read genome sequencing (sr-GS) affords efficient and accurate characterisation of apparently balanced chromosomal rearrangement (ABCR) breakpoints except in 9%-11% of cases that remain undetectable.
Methods: Among 117 ABCR that we studied in patients with abnormal phenotype, 14 (11.9%) could not be detected by our current strategy including sr-GS, alignment against the GRCh38 reference genome and structural variant (SV) detection using Breakdancer V.
