The music focuses on all levels of consciousness and promotes healing through sound and physical response which can reduce anxiety, resulting in relaxation. This study aimed to investigate the effectiveness of Lanna music for relaxation and reducing stress. A randomized controlled trial enrolled 52 persons with mild to moderate stress and/or depression. Participants were randomly assigned to either the experimental group, who listened to Lanna music for 60 minutes, or the control group, who were instructed to lie down in a comfortable position without the Lanna music. In addition, demographic data, blood pressure, heart rate, respiration rate, alpha brain wave frequency and the responses to the relaxation visual analog rating scale were collected. Descriptive statistics, a repeated measures ANOVA, a paired t-test and an independent t-test were used to test the effects of Lanna music in reducing stress. The analysis showed a significant reduction (P < .05) in the mean score of heart rate, respiration rate, and systolic and diastolic blood pressure (P < .05) after listening to the traditional Lanna music. Additionally, there was no significant increase in the mean score of the alpha brain wave after 30 minutes. The study results showed that Lanna music for relaxation had an overall significant effect on stress reduction. Listening to Lanna music can reduce heart rate, respiration rate, and blood pressure, especially increasing the alpha brain waves which has the clinical impact of stress reduction and relaxation responses. These findings indicated the positive effect of traditional Lanna music for relaxation and reducing stress.

HA was used for coating Ti alloy using the electrophoretic deposition dip coating (EP2D) method. The coating applied three variations, including the DC voltages variation of 25 V and 50 V, the withdrawal speeds of 0.1 mm/s, 0.5 mm/s, 1 mm/s, and the calcination temperatures of 750°C and 950°C. Energy dispersive X-Ray spectroscopy (EDS) revealed the Ca/P molar ratio of HA was 1.63, which is close to the stoichiometric ratio of HA at 1.67. The distance between the crystal planes of the HA was 2.81Å. This result also is relative to the crystal plane of the HA at 2.88Å. The EP2D process and the calcination temperature treatment will remove the B-type carbonate apatite phase, so the purity of the HA layer is higher. SEM results show that the HA layer formed was more homogeneous and thicker at the DC voltage of 50 V and the withdrawal velocity of 0.1 mm/s. At this voltage and velocity, minor cracking and agglomeration were produced. The density of the HA layer was higher with increasing calcination temperature and DC voltages.

Swimming exercises were carried out 3x/w for 4 weeks with an intensity of 6% of body weight and the duration was 70% of maximum swimming time. Irisin levels were measured using the ELISA method. The data analysis techniques used were one-way ANOVA test and Tukey's HSD post-hoc test. The results that were obtained from this experimental study were mean levels of irisin in G1 (1.86 ± 0.06 ng/mL), G2 (2.66 ± 0.12 ng/mL), G3 (3.43 ± 0.35 ng/mL), and (P ≤ 0.001).

This study aims to evaluate the mortality and factors related to these in PICU patients treated with vancomycin. A retrospective study was conducted in PICU patients given vancomycin from April 2018 to April 2019. The following variables were included: age, sex, underlying disease, diagnosis, length of stay (LOS) in PICU, Pediatric Index of Mortality 2 (PIM 2) score, mechanical ventilator use, renal replacement therapy (RRT), laboratory data, vancomycin dose, trough serum vancomycin concentration (Ctrough) and mortality rate. One hundred and sixty pediatric patients were enrolled into the study (median age 12 months, range 2-180 months, 69.4% male). Ctrough of vancomycin (10–20 mg/L) was recorded in 32.5% (n = 52) of cases. Septic shock was the most common diagnosis (49.3%) and the mortality rate was 39.4%. Results indicated that children who had a vancomycin Ctrough outside the therapeutic range, mechanical ventilator use and RRT use were statistically significantly associated with higher mortality rate (adjusted OR 3.29, 95% CI, 1.41-7.69; P <0.05), (adjusted OR 6.22, 95% CI, 1.67-23.16; P < 0.05) and (adjusted OR 10.41, 95% CI, 2.62-41.37; P < 0.05).

The aim of this study was to study the protective and osteogenic effects of dodder seed extract at gene expression level in human gingival cells. In this research, dodder seeds were blended and boiled in water before freeze-drying to preserve as dried powder. Total phenolic content and antioxidant assay were performed. MTT assay was performed with human gingival cells. The concentrations of 100, 250 and 500 µg / mL had no effect on cell viability when cultivated for 48 hours. The extract at the concentration of 250 µg / mL was chosen to treat human gingival cells for many time points to observe the expressions of osteogenic, inflammatory, antioxidant and cancer gene markers by real-time PCR. The results showed that dodder seed water extract could increase the expressions of osteogenic markers; OPN, OCN and Col-I genes. Moreover, dodder seed water extract induced mineralization of human gingival cells cultured in 3D structure. Change of BCL2, CAS3 and LC3 expression indicated involvement in apoptotic process of dodder seed water extract. Significant changes in gene expression of antioxidant markers (GST1, SOD1 and TXNRD1), inflammatory marker (Cox-2) and epithelial cell marker (α-SMA) without change of important cancer genes were observed.

The discovery and validation of novel anticancer compounds remains challenging. Garlic has many medicinal properties that can combat various diseases. Organosulfur present in garlic has been shown to induce apoptosis in cancer cells; however, the underlying mechanism of action of non-organosulfur compounds from garlic in controlling cancer cells remains unclear. The present study aimed to analyze the efficacy of organosulfur and non-organosulfur compounds, including the flavonoid, terpenoid, and saponin groups, as inhibitors of C-C chemokine receptor type 5 (CCR5) and C-X-C chemokine receptor type 4 (CXCR4), which play significant roles in the progression of cancer. To determine the interactions between the active compounds of garlic and these receptors (CCR5 and CXCR4), molecular docking was performed using the PyRx v.0.8 software. Amino acid residues were analyzed and visualized using Biovia Discovery Studio and PyMol, respectively. Non-organosulfur compounds exhibited better results than the organosulfur compounds in binding affinity analysis. Tigogenin (from the saponin group) is considered to be a CCR5 inhibitor, while lupeol (from the terpenoid group) is considered to be a CXCR4 inhibitor. In conclusion, our results suggest that garlic compounds could be promising inhibitors of CCR5 and CXCR4, which are highly expressed in cancer. However, further research is needed to validate the in vitro and in vivo activities of garlic compounds for the inhibition of cancer progression.
