Objectives Positive energy homeostasis due to overnutrition and a sedentary lifestyle triggers obesity. Obesity has a close relationship with elevated levels of betatrophin and may increase the risk of developing metabolic syndrome. Therefore, lifestyle modification through a nonpharmacological approach based on physical exercise is the right strategy in lowering betatrophin levels. This study aimed to analyze the effect of moderate-intensity interval and continuous exercises on decreased betatrophin levels and the association between betatrophin levels and obesity markers in women. Methods A total of 30 women aged 20–24 years old were randomly divided into three groups. Measurement of betatrophin levels using Enzyme-Linked Immunosorbent Assay (ELISA). Data analysis techniques used were one-way ANOVA and parametric linear correlation. Results The results showed that the average levels of betatrophin pre-exercise were 200.40 ± 11.03 pg/mL at CON, 203.07 ± 42.48 pg/mL at MIE, 196.62 ± 21.29 pg/mL at MCE, and p=0.978. Average levels of betatrophin post-exercise were 226.65 ± 18.96 pg/mL at CON, 109.31 ± 11.23 pg/mL at MIE, 52.38 ± 8.18 pg/mL at MCE, and p=0.000. Pre-exercise betatrophin levels were positively correlated with age, BMI, FM, WHR, FBG, and PBF (p≤0.001). Conclusions Our study showed that betatrophin levels are decreased by 10 min post-MIE and post-MCE. However, moderate-intensity continuous exercise is more effective in lowering betatrophin levels than moderate-intensity interval exercise. In addition, pre-exercise betatrophin levels also have a positive correlation with obesity markers.

Purpose:We aimed to evaluate surgical outcomes of high-grade bursal rotator cuff-tear repairs. Methods: This systematic review was performed in May 2020 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed. Inclusion criteria were English-language studies reporting the results of pain improvement, functional outcome scores, and radiographic examinations after repair of bursal side partial rotator-cuff tears at any time point in patients of any age and with all levels of evidence. Exclusion criteria were articles not in English, in vitro or animal studies, epidemiological studies, and such article types as technical notes or narrative reviews. Results: Of 58 articles, five were included in this study, of which three and two had level III and IV evidence, respectively, four were comparative studies, and one was a case series. Visual analogue scales were used in four of the five studies, all showing improvement in pain assessment from 5.87 preoperatively to 1.02 postoperatively. All five studies showed significant improvement on each functional outcome score at the final follow-up. The retear rate for all studies was 10.97% (27 of 246). Conclusion: High-grade bursal side partial-thickness rotator cuff-tear repair gave satisfactory results in terms of pain scores, range of motion, and functional outcomes. The retear rate was still considerably high (10.9%), necessitating better understanding of the basic science, such as molecular mechanisms during adaptation, to improve the surgical technique.

Background Melanoma is one of the most aggressive types of cancer and it has shown a remarkable surge in incidence during the last 50 years. Melanoma has been projected to be continuously rising in the future. Therapy for advanced-type melanoma is still a challenge due to the low response rate and poor 10-year survival. Interestingly, several epidemiological and preclinical studies had reported that vitamin D deficiency was associated with disease progression in several cancer types. In vivo and in vitro studies revealed anti-proliferative, anti-angiogenic, apoptosis, and differentiation induction effects of calcitriol in various cancers. However, information on the effects of calcitriol (1,25(OH) 2 D 3 ) on melanoma is still limited, and its mechanism remains unclear. Material/Methods In the present study, by utilizing B16–F10 cells, which is a melanoma cell line, we explored the anti-proliferative effect of calcitriol using cell viability assay, near-infrared imaging, expression of apoptosis-related genes using real-time polymerase chain reactions (PCR), and the expression of apoptosis proteins levels using western blot. In addition, we also assessed calcitriol uptake by B16–F10 cells using high-performance liquid chromatography (HPLC). Results We found that calcitriol inhibits melanoma cell proliferation with an IC 50 of 93.88 ppm (0.24 μM), as shown by cell viability assay. Additionally, we showed that B16–F10 cells are capable of calcitriol uptake, with a peak uptake time at 60 min after administration. Calcitriol was also able to induce apoptosis-related proteins such as caspase-3, caspase 8, and caspase-9. These effects of calcitriol reflect its potential utility as a potent adjuvant therapy for melanoma. Conclusions Calcitriol inhibits cell proliferation and induces apoptosis in B16–F10 cells.

Mangosteen has several important elements for biological activities such as antioxidant, anti-inflammatory, anti-bacterial and anti-cancer. There are γ-mangostin, αmangostin, flavonoids, saponins, and tannins which could stimulate the collagen deposition and accelerate wound healing process. Burn injury cause deep wound in the skin and often cause cicatrix and keloid scar on the skin. However, there is limited information about role of mangosteen in skin wound healing after burn injury. Fifty 10 week-old male rats, were subjected to burn injury using automatic temperature control. Burn injury was created by direct contact of hot plate (170°C) for 15 seconds on rats' inter scapula region. We elaborated the role of extract mangosteen in skin wound healing by applying daily gel contain with active compound derived from mangosteen. There was no significant weight change during treatment period. We observed that there was significant increase of Epidermal Growth Factors (EGF) expression in 14 as shown in immunohistochemistry and confirmed by western blot protein results. Taken together, mangosteen peel extractmediated changes in the expression of growth factors in burned rat skins. Mangosteen peel extract might have a role in the acceleration of skin wound healing.
