To identify the central innervating the mammary nerve, viral retrograde transneuronal labelling methods were employed. Pseudorabies virus 6 microliter was injected into the mammary nerve of adult female Sprague-Dawley rats. After 4 days of survival, the animals were perfused with 4% paraformaldehyde-lysine periodate and their brains were processed for immunohistochemistry and double immunofluorescent staining of Pseudorabies virus or oxytocin using polyclonal antibodies. Several nuclei in brain were retrogradely labelled with Pesudorabies virus.Only a few magnocellular neurons of the paraventricular nucleus throughout whole brain showed double immunoreactivity to Pseudorabies virus and oxytocin. Approximately 11 percent of the oxytocinergic cells of the paraventricular nucleus,especially in three subnuclei[dorsomedial cap, lateral magnocelluar part and ventral part] showed double positive reaction to both Pseudorabies virus and oxytocin. These data demonstrate that some CNS cells projecting to the mammary nerve contained oxytocin and it may acts as a neurotransmitter in this pathway and a hormone targeting milk production and secretion.

The purpose of this study was to evaluate the significance of telomerase activity in gestational trophoblastic disease and the association of telomerase activity in complete hydatidiform mole and subsequent development of persistent gestational trophoblastic tumor. By using the standard telomerase repeat assay, we examined telomerase activity in 2 normal placentas, 31 complete hydatidiform moles, 7 invasive moles, 5 choriocarcinoma tissues and choriocarcinoma cell line (JEG-3). Telomerase activity was detected in 13 of 15 (86.7%) complete hydatidiform mole patients who eventually had chemotherapy for the treatment of persistent gestational trophoblastic tumor. All of the 9 patients with metastatic disease (FIGO Stage III) had telomerase activity in their initial molar tissue. In contrast, telomerase activity was evident in only two of 16 (12.5%) complete hydatidiform mole patients with spontaneous remission. While telomerase activity was not detected in normal placentas, high level of telomerase activity was detected in all of 7 invasive moles, 5 choriocarcinoma tissues and choriocarcinoma cell line (JEG-3). The presence of telomerase activity in a complete hydatidiform mole is associated with the development of persistent gestational trophoblastic tumor, such as invasive mole and choriocarcinoma.

BACKGROUND: Diabetic cardiovascular autonomic neuropathy (CAN) causes perioperative cardiovascular instability. A rapid increase in the desflurane concentration induces tachycardia and hypertension (HTN). This study examined the effects of the cardiovascular response to desflurane on patients with diabetic CAN. METHODS: Forty diabetes mellitus (DM) patients with CAN were divided two groups: one with HTN (DM+HTN group, n = 17) and one without HTN (DM group, n = 23). The control group (n = 20) was composed of healthy patients without DM or HTN. In each group, the concentration of desflurane inspired was increased abruptly to 12.0 vol% 2 minutes after a thiopental injection. The target was to produce an end-tidal concentration of desflurane of 10.0 vol%, which was maintained until the end of the study by adjusting the vaporizer dial setting. The heart rate (HR), mean arterial pressure (MAP), and cardiac index (CI) were measured. RESULTS: The HR, MAP and CI increased significantly in all three groups when compared with the baseline (P<0.05). Additionally, the HR and MAP showed did not differ among the three groups at any of sampling times. However, the CI of the DM group and the DM+HTN group differed when compared with the control group at 90 and 120 seconds after intubation (P<0.05). CONCLUSIONS: In diabetic patients with CAN, the hemodynamic responses to a rapid increase in desflurane concentration are similar to those in non-diabetic patients before endotracheal intubation. However, after endotracheal intubation, increments in CI are blunted in diabetic patients with CAN.

Purpose: This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. Methods: A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, x 2 test and logistic regression analysis were statistical tools used to analyze the data. Results: In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. Conclusion Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.

Purpose: To evaluate the surgical outcomes of a perfluoro-n-octane (PFO)-assisted superior inverted internal limiting membrane (ILM) flap without the peeling-off technique for the treatment of a large macular hole (MH). Methods: This retrospective interventional case series examined 13 eyes with a MH ≥ 400 μm. All eyes underwent 25-gauge pars plana vitrectomy. An ILM flap stained with 0.025% brilliant blue G was made in the superior area of the hole. The ILM in the temporal, nasal, and inferior areas around the hole was not peeled off. The hole was gently covered using the inverted ILM flap, which was stabilized using a small amount of PFO. Fluidair exchange was performed slowly. The small amount of residual PFO was removed by evaporation. The patients were instructed to maintain a facedown position for 1 day postoperatively. Anatomical closure of the hole and visual acuity were assessed postoperatively. Results: The average hole size was 605.08 ± 102.41 μm. Nine eyes had an idiopathic MH, two exhibited age-related macular degeneration, and one each had high myopia and a traumatic MH. All eyes achieved type I closure. The foveal contour improved gradually during follow-up: 92.3% of eyes had a U-shaped fovea, and 61.5% exhibited complete recovery of the ellipsoid zone. The visual acuity improved from 0.91 to 0.55 logarithm of the minimum angle of resolution (p = 0.003). Conclusions The PFO-assisted superior inverted ILM flap without peeling-off was effective for stabilizing the flap over the hole and consequently achieving good anatomical and visual outcomes in large MHs.

Background: Aerobic exercise training and drug therapy are well-established interventions for the prevention and treatment of hypertension and dyslipidemia. We investigated the synergistic effects of aerobic exercise and olmesartan/rosuvastatin on epicardial fat thickness (EFT) and endothelial function in patients with hypertension and dyslipidemia. Methods: A sample of 75 participants with hypertension and dyslipidemia was evaluated for multifactorial cardiovascular risk at baseline and at 6 months of intervention according to anthropometric and hemodynamic components, lipid profile, glycemia, brachial artery flow-mediated dilation (FMD), and EFT. After 3 months of drug therapy only, participants were allocated to one of three conditions: treadmill (n=22), exergame (n=29), or control (n=24). Results: After 12 weeks of drug therapy only, systolic and diastolic blood pressure (3% and 2%, both p<0.05), total cholesterol (6.3%, p<0.01), low-density lipoprotein cholesterol (4.9%, p<0.05), triglycerides (11.1%, p<0.05), fasting blood glucose (10.2%, p<0.01), and glycosylated hemoglobin (3%, p<0.01) were significantly reduced. After 12 weeks of combined aerobic exercise and drug therapy, both the treadmill and exergame groups showed a significant improvement in FMD (both p<0.001) and reduction in EFT (both p<0.001). Systolic and diastolic blood pressures decreased in the treadmill group only (1.9% and 2.7%, respectively, p<0.05). Conclusions Incorporating aerobic exercise into drug therapy regimens can yield synergistic effects, particularly in improving endothelial function and reducing EFT, providing a comprehensive approach to managing cardiovascular risk in patients with hypertension and dyslipidemia.
