Periodontal response to nonsurgical accelerated orthodontic tooth movement.
Periodontol 2000
January 2025
ADA Forsyth Institute, Cambridge, Massachusetts, USA.
Tooth movement is a complex process involving the vascularization of the tissues, remodeling of the bone cells, and periodontal ligament fibroblasts under the hormonal and neuronal regulation mechanisms in response to mechanical force application. Therefore, it will inevitably impact periodontal tissues. Prolonged treatment can lead to adverse effects on teeth and periodontal tissues, prompting the development of various methods to reduce the length of orthodontic treatment.

Photobiology Applied to Health (PhotoBioS) - Research and Development Institute- R&DI, University of Vale do Paraíba, Univap. Shishima Hifumi Avenue, 2911, 12244-000, São José dos Campos, São Paulo, Brazil. Electronic address:
Acinetobacter baumannii stands out for its antimicrobial resistance and high capacity to cause hospital infections, posing a severe threat to global public health. Thus, there is an urgent need for new therapeutic strategies. This work applied photodynamic therapy (PDT) with curcumin to Acinetobacter baumannii, and bacterial cell viability was assessed.

Aging Ment Health
January 2025
Institute for Applied Social Sciences, Cener Health, Music Therapy Lab, Technical University of Applied Social Sciences Würzburg-Schweinfurt, Würzburg, Germany.
Objectives: Due to the limited effectiveness of pharmacological treatment, there is a growing need to explore non-pharmacological psychosocial interventions such as music therapy when treating the behavioural and psychological symptoms of dementia (BPSD).
Method: We randomised 57 nursing home residents into individual active music therapy plus standard care (aMT), individual receptive music therapy with tactile sound vibration plus standard care (rMT), or the standard care control group (CG). A trained music therapist provided 12 sessions over 6 weeks.
Application of fourier transform infrared vibrational spectroscopy in identifying early biochemical changes in lipid profiles of individuals undergoing Roux-en-y gastric bypass.
BMC Surg
January 2025
Postgraduate Program in Nutrition and Health, Health Sciences Center, Federal University of Espírito Santo, Av. Mal. Campos, 1468 - Maruípe, Vitória, 29047-100, ES, Brazil.
Background: Fourier transform infrared spectroscopy (FTIR) is an analytical technique increasingly applied in biological analysis. This study investigates the application of FTIR to identify early biochemical changes, particularly in lipid profiles, in individuals undergoing Roux-en-Y gastric bypass (RYGB).
Methods: An observational study involving patients from a university hospital's Bariatric and Metabolic Surgery Program, with evaluations performed before (T0) and two months after (T1) RYGB.
Raman, ROA, and luminescence spectra of chiral lanthanide complexes with L- and D-alanine.
Spectrochim Acta A Mol Biomol Spectrosc
January 2025
Laboratory for Spectroscopy, Molecular Modeling and Structure Determination, Institute of Nuclear Chemistry and Technology, 16 Dorodna Street, 03-195 Warsaw, Poland. Electronic address:
The Raman spectra of lanthanide [Ln(HO)(Ala)](ClO) crystals were measured with 488, 532, 633, and 1064 nm laser lines, and ROA of complexes in water were collected using 532 nm excitation. As in IR and VCD, ν(CO) stretching and β(OCO) bending vibration bands showed a tendency typical to the lanthanide contraction effect. However, in Raman, the effect is less pronounced than the IR spectrum because it is strongly perturbed by lanthanide ion luminescence, which comes from the 4f → 4f transitions.
