A Retrospective Pragmatic Longitudinal Case-Series Clinical Study to Evaluate the Clinical Outcome of Triple-Frequency Ultrasound in Treatment of Cellulite.

Objective: In this single-centre, retrospective, pragmatic, longitudinal case-series clinical study triple-frequency LDM (TF-LDM) technology with frequencies of 1/3/10 MHz and 3/10/19 MHz was applied for treatment of cellulite to reveal the effect of these waves on the cellulite skin and assess the sustainability of treatment outcomes during the long-term follow-up controls.

Methods: Twenty Caucasian females with mild-to-severe gynoid lipodystrophy aged 27-53 years who received cellulite monotherapy with TF-LDM were included in this study. All participants were evaluated at three time points: baseline (T1), on the day of the last treatment (T2), and during the last follow-up (T3).

Cortical assembloids support the development of fast-spiking human PVALB+ cortical interneurons and uncover schizophrenia-associated defects.

Disruption of parvalbumin positive (PVALB+) cortical interneurons is implicated in the pathogenesis of schizophrenia. However, how these defects emerge during brain development remains poorly understood. The protracted maturation of these cells during postnatal life has made their derivation from human pluripotent stem cells (hPSCs) extremely difficult, precluding hPSC-based disease modeling of their role in neuropsychiatric disease.

A Retrospective Pragmatic Two-Center Clinical Study to Evaluate the Clinical Outcome of Triple-Frequency Ultrasound in the Treatment of Mild-to-Severe Acne Vulgaris.

Objectives: Earlier, quickly alternating dual-frequency ultrasound waves (LDM technology) were successfully applied for the treatment of different inflammatory skin conditions such as rosacea and acne. In this retrospective pragmatic two-center clinical study, we applied the triple-frequency LDM (TF-LDM) technology with frequencies of 1/3/10 and 3/10/19 MHz for the treatment of mild-to-severe acne skin to assess the effectivity and sustainability of the treatment outcomes.

Methods: Twenty-two patients with mild-to-severe acne were included in this study: 11 patients were treated with TF-LDM (1/3/10 MHz), and other 11 patients-with TF-LDM (3/10/19 MHz).

Effects of microgravity on human iPSC-derived neural organoids on the International Space Station.

Research conducted on the International Space Station (ISS) in low-Earth orbit (LEO) has shown the effects of microgravity on multiple organs. To investigate the effects of microgravity on the central nervous system, we developed a unique organoid strategy for modeling specific regions of the brain that are affected by neurodegenerative diseases. We generated 3-dimensional human neural organoids from induced pluripotent stem cells (iPSCs) derived from individuals affected by primary progressive multiple sclerosis (PPMS) or Parkinson's disease (PD) and non-symptomatic controls, by differentiating them toward cortical and dopaminergic fates, respectively, and combined them with isogenic microglia.

Establishing Neural Organoid Cultures for Investigating the Effects of Microgravity in Low-Earth Orbit (LEO).

Recent findings from studies involving astronauts and animal models indicate that microgravity increases immune cell activity and potentially alters the white and gray matter of the central nervous system (CNS). To further investigate the impact of microgravity on CNS cells, we established cultures of three-dimensional neural organoids containing isogenic microglia, the brain's resident immune cells, and sent them onboard the International Space Station. When using induced pluripotent stem cell (iPSC) lines from individuals affected by neuroinflammatory and neurodegenerative diseases such as multiple sclerosis (MS) and Parkinson's disease (PD), these cultures can provide novel insights into pathogenic pathways that may be exacerbated by microgravity.
