Background and Aim: The combination of vitrification techniques and in vitro maturation can reduce oocyte competence. Mitogen-activated protein kinase and maturation-promoting factor are significant in oocyte meiotic maturation regulation. This study aimed to analyze vitrification's effect, after warming followed by in vitro maturation, on the expressions of protein 38 (p38), cyclin-dependent kinase 1 (CDK1), and cyclin B and oocyte maturation level. Materials and Methods: Immature goat oocytes were soaked in vitrification and warming solutions. The procedure was followed by in vitro maturation and in vitro maturation without post-warming vitrification as a control. These oocytes, along with their cumulus, were vitrified using hemistraw in liquid nitrogen. Oocyte maturation was carried out in a maturation medium that was added with 10 μg/mL of FSH, 10 μg/mL of LH, and 1 μg/mL E2 for 22 h. The expressions of p38, CDK1, and cyclin B were observed using immunocytochemical methods, which were assessed semiquantitatively according to the modified Remmele method. The oocyte maturation level was observed using the aceto-orcein staining method based on the achievement of chromosomes up to the metaphase II stage and/or the formation of the polar body I. Results: p38 expression in vitrified oocytes after warming, followed by in vitro maturation, increased insignificantly (p≥0.05), with the acquisition of 3.91±2.69 and 2.69±0.50 in the control oocytes. CDK1 expression in vitrified oocytes decreased significantly (p≤0.05) after warming, followed by in vitro maturation, with the acquisition of 2.73±1.24 and 7.27±4.39 in the control oocytes. Cyclin B expression in vitrified oocytes decreased insignificantly (p≥0.05) after warming, followed by in vitro maturation, with the acquisition of 3.09±1.4 and 4.18±2.61 in the control oocytes. The proportion of vitrified oocyte maturation levels after warming, followed by in vitro maturation, decreased significantly (p≤0.05), with the acquisition of 45.45% and 77.27% in the control oocytes. Conclusion: This study concluded that vitrification after warming resulted in an insignificant increase in p38 expression, a significant decrease in CDK1 expression, an insignificant decrease in cyclin B expression, and a significant reduction in oocyte maturation levels.
Highlights:1. Most senior high school students live a sedentary lifestyle.2. Hyperinsulinemia and hyperandrogenism were related to an increased risk of PCOS in adolescents.3. Sedentary lifestyle and overweight were found to have a significant correlation with increased risk of PCOS in adolescents. AbstractIntroduction: Adolescent polycystic ovary syndrome (PCOS) is one of the endocrine and metabolic disorders characterized by oligomenorrhea and hyperandrogenism. A sedentary lifestyle in adolescence increases the risk of overweight and obesity. Being overweight may increase the risk of PCOS in adolescents by the mechanism of insulin resistance and hyperinsulinemia, which affects the function of adrenal and ovarium androgen production. The increase of androgen has an important effect on PCOS. This study aimed to examine the relationship between a sedentary lifestyle and being overweight as the risk of PCOS in adolescents.Methods: This was an observational analytic study with a cross-sectional design. This study was held at State Senior High School (SMAN) 5 Surabaya from February to April 2020. The sample of this research was chosen by random sampling of all female students in SMAN 5 Surabaya. The data were collected by direct measurement of student’s weight and height and a questionnaire consisting of Global Physical Activities Questionnaire, menstrual cycle, and Ferriman–Gallwey score. The students were stated at risk of PCOS if they had an abnormal uterine bleeding pattern and had Ferriman–Gallwey score ≥5. The data were analyzed using logistic regression analysis.Results: Of 82 students (100%), 32 students were overweight (39%), 5 students had obesity (6.1%), 44 students were performing a sedentary lifestyle (53.7%), 42 students had Ferriman–Gallwey score ≥5 (51.2%), 38 students had an abnormal uterine bleeding pattern (43.3%), and 35 students were at risk of PCOS (42.6%). Logistic regression analysis showed there was a significant relationship between a sedentary lifestyle and the risk of PCOS (p = 0.004) and a significant relationship between being overweight and the risk of PCOS (p < 0.001). People with a sedentary lifestyle have 6.3 folds higher risk of PCOS than normal people, and people with overweight have 16.2 folds higher risk of PCOS than normal people.Conclusion: Sedentary lifestyle and overweight have the role of increasing the risk of PCOS in adolescents.
background: Implant as long-acting reversible contraception (LARC) is ideal for Indonesian women. Two-rod implant (2x75mg levonorgestrel) is the most common implant used in Indonesia. Another alternative method is a one-rod implant (1x150mg levonorgestrel). objective: This study evaluated the effectiveness, changes in body weight (BW), and menstrual cycle between the one-rod and two-rod implant acceptors. method: This study was an RCT design with phase II clinical trials; 179 subjects were recruited. Subjects were met with inclusion and exclusion criteria and divided into one-rod and two-rod groups. The variables were evaluated within 12 months. result: This study involved 70 subjects in the one-rod implant group and 66 subjects in the two-rod implant group. At 12 months, there were no differences between the effectiveness of the two types of contraception, and pregnancy was reported in 1.26% vs 1.31%. The concentration of levonorgestrel in the one-rod group was 0.31 ng/dL as the median (IQR: 0.33 ng/dL) and 0.34 ng/dL as the median (IQR: 0.33 ng/dL) in the two-rod group (p=0.438). The BW in the two-rod group increased significantly in month six (p=0.035) and twelve (p=0.017) but not in the one-rod group. Menstrual cycle changes occurred in 51.4% of subjects and 57.6% of subjects in the one- and two-rod groups (p=0.584), respectively. conclusion: At 12 months, one-rod and two-rod implants had similar effectiveness and concentration of levonorgestrel. Significant weight gain happened in the two-rod group, and the weight gain increased in months six and twelve. Menstrual cycle changes have occurred in both.
Introduction: Vaginal laxity, a symptom of pelvic floor dysfunction observed in women, has many negative biological and psychological impacts. Laser treatments and stem cell-based therapies are emerging therapeutic methods for treating this condition. This study aimed to determine changes in vaginal laxity in model rats using a combination therapy of erbium-doped yttrium aluminium garnet (Er:YAG) fractional lasers and topical treatment with amniotic membrane stem cell metabolite products (AMSC-MP). Methods: The experimental animal population comprised 36 female white rats (Rattus norvegicus; 2-day-post-vaginal-delivery rats) allocated into the following four groups (n=9): K1, untreated two-day-post-vaginal-delivery rats; K2, two-day-post-vaginal-delivery rats treated with topical gel without AMSC-MP; P1, two-day-post-vaginal-delivery rats treated with Er:YAG fractional lasers and topical gel without AMSC-MP; P2, two-day-post-vaginal-delivery rats treated with Er: YAG fractional lasers and topical gel containing AMSC-MP. Immunohistochemical (IHC) examination was carried out for the expression and activity of heat shock protein 70 (HSP-70), collagen-1, tissue inhibitors of metalloproteinase 1 (TIMP-1) and matrix metalloproteinase 1 (MMP-1), as well as vaginal mucosal thickness. Results: There was a significant difference (P<0.05) in the expression of HSP-70 among all groups except K2 and P1 (P>0.05); there was no significant difference in type I collagen and TIMP-1 expression between the groups (P>0.05); there was a significant difference (P<0.05) in MMP-1 activity, with the activity in the K2 group (5.79±0.83) being higher than that in the P1 group (4.44±1.82) and that in the K1 group (5.74±1.03) being higher than that in the P2 group (4.24±1.55). Also, there was a significant difference in the thickness of the vaginal mucosa in all groups except K2 and P1 (P>0.05). Conclusion: Er:YAG fractional laser and AMSC-MP combination therapy improved vaginal laxity in model rats by increasing Hsp70 expression and vaginal mucosal thickness and decreasing MMP-1 activity.
Context: Polycystic ovary syndrome (PCOS) is significantly associated with inflammation and oxidative stress. Syzygium polyanthum is a plant rich in pharmacological properties. Aims: To evaluate the anti-inflammation and antioxidant potential of S. polyanthum bioactive compounds using in silico approach. Methods: The S. polyanthum was extracted using the ultrasound-assisted extraction (UAE) method, and the bioactive compounds were screened using Liquid Chromatography–High Resolution Mass Spectrometry (LC-HRMS) analysis. This study predicted the biological activity of S. polyanthum compounds using PASS Online server. Before docking, we analyzed the protein-protein interactions (PPIs) network of TNFα, NF-kB, SOD, and KEAP1. The molecular docking was done using Autodock Vina in PyRx software and visualized using Discovery Studio. Probability to be active (Pa) was determined. Results: The bioactive compounds found in S. polyanthum and used in this study were deoxyphomalone, NCGC00169066-01, and phloretin with retention times [min] of 0.886, 0.907, and 8.323, respectively. The predicted biological activity of compounds and controls were anti-inflammatory, immunosuppressant, TNF expression inhibitor, immunomodulatory and HIF1α expression inhibitor (Pa>0.5 for all S. polyanthum compounds and Pa<0.5 for SPD304, MG-132, and MDF). Based on PPIs network analysis, TNFα, NF-kB, SOD, and KEAP1 are associated. The molecular docking analysis showed that deoxyphomalone, NCGC00169066-01, and phloretin had inhibition potential against TNFα and NF-kB, and activation potential against SOD, due to several residues involved in the interaction of compounds-protein was the same as the interaction of inhibitor (SPD-304 and MG-132) and activator (gallic acid) control against the protein. The residues may have the same inhibition or activation mechanism as the control. However, S. polyanthum bioactive compounds may still have inhibition potential against KEAP1 through Ala548 residue that is also involved in the interaction of DMF-KEAP1. Conclusions: The bioactive compounds of S. polyanthum showed anti-inflammation and antioxidant potential, which may have a good effect in the treatment of PCOS, yet still need to be confirmed in vitro or in vivo research.
