Abstract
Self-mutilation lesions can represent a clinical diagnosis challenge for healthcare professionals, as patients do not admit to self-mutilation. This leads to failed diagnoses due to the similarity of this condition to other diseases. Searches on the subject were carried out at the PubMed, Periódicos Capes, Scopus, Science Direct and WoS databases, according to the following inclusion criteria: articles in English, Portuguese or Spanish, published from 2018 to June 2023, encompassing case reports, case series and literature reviews. Men are slight more affected by self-mutilation injuries, also presenting the most serious lesions. Self-mutilation injuries are reported globally, mostly in the Asian and American continents. Clinical presentations are varied, but morphology is, in most cases, associated to the form/instrument used for self-mutilation. Greater evidence of diagnosed mental disorders in women and underreporting of these cases in men due to low demands for specialized treatment are noted. A higher prevalence of self-mutilation lesions was verified for men, affecting a wide age range, with the highest number of cases in the USA. The most affected body areas are arms and external genitalia, mostly due to knife use. An association between self-mutilation injuries and mental disorders is clear, with most cases being previously undiagnosed.

Abstract
Polylactic Acid (PLA) and Acrylonitrile-Butadiene-Styrene (ABS) are commonly used polymers in 3D printing for biomedical applications. Dental Pulp Stem Cells (DPSCs) are an accessible and proliferative source of stem cells with significant differentiation potential. Limited knowledge exists regarding the biocompatibility and genetic safety of ABS and PLA when in contact with DPSCs. This study aimed to investigate the impact of PLA and ABS on the adhesion, proliferation, osteogenic differentiation, genetic stability, proteomics, and immunophenotypic profile of DPSCs. A total of three groups, 1- DPSC-control, 2- DPSC+ABS, and 3- DPSC+PLA, were used in in vitro experiments to evaluate cell morphology, proliferation, differentiation capabilities, genetic stability, proteomics (secretome), and immunophenotypic profiles regarding the interaction between DPSCs and polymers. Both ABS and PLA supported the adhesion and proliferation of DPSCs without exhibiting significant cytotoxic effects and maintaining the capacity for osteogenic differentiation. Genetic stability, proteomics, and immunophenotypic profiles were unaltered in DPSCs post-contact with these polymers, highlighting their biosafety. Our findings suggest that ABS and PLA are biocompatible with DPSCs and demonstrate potential in dental or orthopedic applications; the choice of the polymer will depend on the properties required in treatment. These promising results stimulate further studies to explore the potential therapeutic applications in vivo using prototyped polymers in personalized medicine.

Abstract
The objective was to evaluate the effect of human adipose-derived stem cell (hADSC) infusion on impaired hindlimb function and urinary continence after spinal cord contusion in rats. hADSCs were transplanted into the injured spinal cords of rats 7 and 14 days after injury in two groups (B and C). Group C also received methylprednisolone sodium succinate (MPSS) after 3 h of injury. The control group (group A) did not receive corticoids or stem cells. Voiding and motor performance evaluations were performed daily for 90 days post-transplantation. Cells were labeled with PKH26 or PKH67 for in vitro monitoring. For in vivo screening, the cells were evaluated for bioluminescence. The levels of some cytokines were quantified in different times. Euthanasia was performed 90 days post-transplant. β-tubulin III expression was evaluated in the spinal cord of the animals from all groups. As a result, we observed a recovery of 66.6 % and 61.9 % in urinary continence of animals from groups B and C, respectively. Partial recovery of motor was observed in 23.8 % and 19 % of the animals from groups B and C, respectively. Cells remained viable at the site up to 90 days after transplantation. No significant difference was observed in levels of cytokines and thickness of urinary bladders between groups. A smaller percentage of tissue injury and higher concentrations of neuropils were observed in the spinal cords of the animals from groups B and C than control group. Thus, hADSCs transplantation with or without MPSS, contributed to the improvement in voiding and motor performance of Wistar rats submitted to compressive spinal cord injury.

Abstract
Mesenchymal stem cell (MSC) research has demonstrated the potential of these cells to modulate lung inflammatory processes and tissue repair; however, the underlying mechanisms and treatment durability remain unknown. Here, we investigated the therapeutic potential of human bone marrow-derived MSCs in the inflammatory process and pulmonary remodeling of asthmatic BALB/c mice up to 14 d after transplantation. Our study used ovalbumin to induce allergic asthma in male BALB/c mice. MSCs were injected intratracheally in the asthma groups. Bronchoalveolar lavage fluid (BALF) was collected, and cytology was performed to measure the total protein, hydrogen peroxide (H2O2), and proinflammatory (IL-5, IL-13, and IL-17A) and anti-inflammatory (IL-10) interleukin (IL) levels. The lungs were removed for the histopathological evaluation. On day zero, the eosinophil and lymphochte percentages, total protein concentrations, and IL-13 and IL-17A levels in the BALF were significantly increased in the asthma group, proving the efficacy of the experimental model of allergic asthma. On day 7, the MSC-treated group exhibited significant reductions in the eosinophil, lymphocyte, total protein, H2O2, IL-5, IL-13, and IL-17A levels in the BALF, while the IL-10 levels were significantly increased. On day 14, the total cell numbers and lymphocyte, total protein, IL-13, and IL-17A levels in the BALF in the MSC-treated group were significantly decreased. A significant decrease in airway remodeling was observed on days 7 and 14 in almost all bronchioles, which showed reduced inflammatory infiltration, collagen deposition, muscle and epithelial thickening, and mucus production. These results demonstrate that treatment with a single injection of MSCs reduces the pathophysiological events occurring in an experimental model of allergic asthma by controlling the inflammatory process up to 14 d after transplantation.

Abstract
OBJECTIVE The aim of the present study was to analyse the characteristics of salivary production and its composition in individuals with burning mouth syndrome (BMS). STUDY DESIGN Salivary flow rate, concentrations of potassium, iron, chloride, thiocyanate, magnesium, calcium, phosphorus, glucose, total protein and urea, as well as the expression profile of salivary proteins were analysed by SDS-PAGE. RESULTS The mean salivary flow rate among control patients was lower than that of BMS patients. Chloride, phosphorus and potassium levels were elevated in patients with BMS (p = 0.041, 0.001 and 0.034, respectively). Total salivary protein concentration was reduced in individuals with BMS (p = 0.223). Analysis of the expression of salivary proteins by Coomassie blue SDS-PAGE revealed a lower expression of low molecular weight proteins in individuals with BMS compared to healthy controls. CONCLUSIONS These results indicate that the identification and characterisation of low molecular weight salivary proteins in BMS may be important in understanding BMS pathogenesis, thus contributing to its diagnosis and treatment.
