The level of cyclic nucleotides in biological material undergoes changes due to endoscopic treatment of gastric and duodenal ulcers with the help of helium-neon laser radiation which, in addition to dynamics of the clinical picture and gastroduodenoscopic data, makes it possible to diagnose the disease remission and in certain cases to predict the course of peptic ulcer.

This study aims to assess the effects of aquatic training (AT) and its combination with photobiomodulation (PBM) on cytokine synthesis and plantar muscle morphology during compensatory hypertrophy (H) in Wistar rats. H was induced by bilateral ablation of synergistic muscles, and PBM using a laser (780 nm). AT involved 60 min sessions, 5 times/week, for 7 and 14 days.

This in-vitro study assessed the influence of the shade of human teeth on the transmission of near-infrared light. A total of 40 teeth were used. After cleaning the root surface and removing cementum, the teeth were sectioned into slices 3 mm thick, with each comprising a portion of the crown (enamel-dentine (ED)) and of the root (dentine only).

Spinal cord injury (SCI) is a significant cause of lifelong disability, with no available disease-modifying treatments to promote neuroprotection and axon regeneration after injury. Photobiomodulation (PBM) is a promising therapy which has proven effective at restoring lost function after SCI in pre-clinical models. However, the precise mechanism of action is yet to be determined.

Phase transitions in the mantle control its internal dynamics and structure. The post-spinel transition marks the upper-lower mantle boundary, where ringwoodite dissociates into bridgmanite plus ferropericlase, and its Clapeyron slope regulates mantle flow across it. This interaction has previously been assumed to have no lateral spatial variations, based on the assumption of a linear post-spinel boundary in pressure and temperature.

Synergistic therapy combining photothermal therapy (PTT) and chemodynamic therapy (CDT) has proven to be a highly effective strategy for cancer treatment. However, PTT heavily relies on the accumulation of therapeutic agents at the tumor site. The peroxidase (POD) activity of common catalysts can be rapidly exhausted during the accumulation process, prior to laser intervention, thereby diminishing the synergistic enhancement effect of the combined therapy.
