Purpose: To investigate the effect of conservative treatment of unilateral condylar fractures on jaw symmetry in children.
Methods: Twenty-four children with unilateral condylar fractures were divided into control group and experimental group according to the treatment methods, with 12 cases in each group. The control group received surgery, and the experimental group received conservative treatment with intermaxillary traction combined with occlusal pads. The treatment effects of the two groups were compared, and the imaging improvement, three-dimensional structure of the jaw, mandibular motor and occlusal relationship, and facial nerve injury were compared after treatment. SPSS 17.0 software package was used for statistical analysis.
Results: There was no significant difference in the total effective rate, total effective rate of imaging, disturbance of occlusal relationship, and incidence of facial nerve injury between the two groups (P>0.05). The transverse diameter of the condyles was significantly longer in the experimental group than in the control group, and the width of the condyles and bony condylar deflection in the experimental group were significantly smaller than those in the control group (P<0.05). The degree of mouth opening after treatment in both groups was increased, which was more remarkably in the experimental group after treatment than in the control group (P<0.05).
Conclusions: Children with unilateral condylar fractures can obtain similar treatment effects with surgical treatment with conservative treatment. After treatment, the children's mandibular motor function and jaw symmetry are well restored.

Current fetal alcohol spectrum disorders (FASD) studies primarily focus on alcohol's actions on the fetal brain although respiratory infections are a leading cause of morbidity/mortality in newborns. The limited studies examining the pulmonary adaptations in FASD demonstrate decreased surfactant protein A and alveolar macrophage phagocytosis, impaired differentiation, and increased risk of Group B streptococcal pneumonia with no study examining sexual dimorphism in adaptations. We hypothesized that developmental alcohol exposure in pregnancy will lead to sexually dimorphic fetal lung morphological and immune adaptations.

Background: Visual Thinking Strategies (VTS) is an evidence-based pedagogical approach that uses art analysis and structured inquiry to enhance observation, critical thinking, and teamwork, especially in medical training for clinical skills development. This study aimed to compare the short-term and delayed follow-up effects of integrating Visual Thinking Strategies and Visual Thinking Activity (VTA) tasks based on the PRISM Model with Observation Exercises (OE) on medical students' observation skills, including the number of observations, number of words used, and time spent describing observations.
Method: This pre- and post-test experimental study with a control group was conducted among first-year medical students at Gonabad University of Medical Sciences during the 2023-2024 academic year.

Background: Lung adenocarcinoma is the most common form of lung cancer and one of the most life-threatening malignant tumors. Ferroptosis is an iron-dependent regulatory cell death pathway that is crucial for tumor growth. SNX30 is a key regulatory factor in cardiac development; however, its regulatory mechanism and role in inducing ferroptosis in lung adenocarcinoma remain unclear.

Background: Prophylactic parenteral administration of antibiotics is strongly recommended to prevent surgical site infection (SSI). Cefoxitin is mainly administered intravenously in colorectal surgery. The current standard method for administering prophylactic antibiotics in adults is to administer a fixed dose quickly before skin incision.
