In the nasopharynx, AD1-PNS, AD2-PNS, PNS-Ba and PNS-Ho measurements revealed a significant increase in the SA group compared to the other groups (P<.05). In the oropharynx, PNS-Ep measurement increased significantly in the RME group (P<.05). In the total pharyngeal airway area, an increase was detected in the SA, Alt-RAMEC, and RME groups.
The most effective protraction method in terms of pharyngeal airway dimensions, especially in the nasopharynx, is the application of the face mask with skeletal anchorage. A greater increase in vertical airway length (PNS-Ep) was observed with RME.

Therefore, the prediction of the immunomodulatory bioperformance of biomedical devices following implantation is of utmost importance. Herein, liquefied capsules are proposed as immunomodulatory miniaturized 3D platforms for the high-content combinatorial screening of different polymers that could be used generically in scaffolds. Additionally, the confined and liquefied core of capsules affords a cell-mediated 3D assembly with bioinstructive microplatforms, allowing to study the potential synergistic effect that cells in tissue engineering therapies have on the immunological environment before implantation. As a proof-of-concept, three different polyelectrolytes, ranging in charge density and source, are used. Poly(L-lysine)-, alginate-, and chitosan-ending capsules with or without encapsulated mesenchymal stem/stromal cells (MSCs) are placed on top of a 2D culture of macrophages. Results show that chitosan-ending capsules, as well as the presence of MSCs, favor the balance of macrophage polarization toward a more regenerative profile, through the up-regulation of anti-inflammatory markers, and the release of pro-regenerative cytokines. Overall, the developed system enables the study of the immunomodulatory bioperformance of several polymers in a cost-effective and scalable fashion, while the paracrine signaling between encapsulated cells and the immunological environment can be simultaneously evaluated.Targeted drug delivery using a microrobot is a promising technique capable of overcoming the limitations of conventional chemotherapy that relies on body circulation. However, most studies of microrobots used for drug delivery have only demonstrated simple mobility rather than precise targeting methods and prove the possibility of biodegradation of implanted microrobots after drug delivery. In this study, magnetically guided self-rolled microrobot that enables autonomous navigation-based targeted drug delivery, real-time X-ray imaging, and microrobot retrieval is proposed. The microrobot, composed of a self-rolled body that is printed using focused light and a surface with magnetic nanoparticles attached, demonstrates the loading of doxorubicin and an X-ray contrast agent for cancer therapy and X-ray imaging. The microrobot is precisely mobilized to the lesion site through automated targeting using magnetic field control of an electromagnetic actuation system under real-time X-ray imaging. The photothermal effect using near-infrared light reveals rapid drug release of the microrobot located at the lesion site. After drug delivery, the microrobot is recovered without potential toxicity by implantation or degradation using a magnetic-field-switchable coiled catheter. This microrobotic approach using automated control method of the therapeutic agents-loaded microrobot has potential use in precise localized drug delivery systems.Lasers are effective treatments for benign hyperpigmentations but may be difficult especially in darker skin type. In this randomized split-face controlled study on benign hyperpigmentations and pigmented scars, we compare the standard Single Pass (SP) emission with the MultiPass emission (MoveoPL) 755 alexandrite laser. Patients, skin types I-IV, with solar lentigines and ephelides of the face, chest, and hands and patients with pigmented scars of the legs, underwent laser treatment, by treating one side of the body or half scar using the SP and the other side using MoveoPL. Improvements according to a grading score system, side effects, and patient satisfaction were recorded. About 63 patients were enrolled. An overall improvement of benign hyperpigmentations and pigmented scars was recorded, with a grading score (±SD) of 2.8 ± 0.8 for SP and 3.6 ± 0.5 for MoveoPL (range, 0-4). SP emission showed best results in skin types I-II whereas MotusPL obtained successfully results in all the phototypes analyzed (types I-IV). Patients preferred MoveoPL as it was associated with fewer side effects. Both standard SP and MoveoPL emission are effective and safe. MoveoPL showed a higher efficacy and safety profile for the treatment of hyperpigmentations.
To examine the patterns of cortical gray matter thickness in multiple sclerosis (MS) patients.
Seventy-four MS patients-clinically isolated syndrome (4%), relapsing-remitting MS (79%), and progressive MS (17%)-and 21 healthy controls (HCs) underwent 1.5Tesla T1-weighted 3D MRI examinations to measure brain cortical thickness in a total of 68 regions of interest. Using hierarchical cluster analysis with multivariate cortical thickness data, cortical thickness reduction patterns were cross-sectionally investigated in MS patients.
The MS patients were grouped into three major clusters (Clusters 1, 2, and 3). Most of the regional cortical thickness values were equivalent between the HCs and Cluster 1, but decreased in the order of Clusters 2 and 3. Only the thicknesses of the temporal lobe cortices (the bilateral superior and left middle temporal cortex, as well as the left fusiform cortex) were significantly different among Clusters 1, 2, and 3. In contrast, temporal pole thickness reduction was evident ex in the progressive phase.
