Microwaves (MWs) deliver relatively high temperatures into biological tissue and cover a large ablation zone. This study aims to evaluate the efficacy and effectiveness of water-cooled double-needle MW ablation arrays in assisting the hepatic transection of an pig model. Our research program comprised computer modeling, tissue-mimicking phantom experiments, and pig liver experiments. Computer modeling was based on the finite element method (FEM) to evaluate ablation temperature distributions. In tissue-mimicking phantom and pig liver ablation experiments, the performances of the water-cooled MW ablation array and conventional clamp crushing liver resection were compared. FEM showed that the maximum lateral ablation diameter at 100 W output and a duration of 60 s was 3 cm (assessed at 50 °C isotherm). In the phantom, the maximum transverse ablation diameter of the double-needle MW ablation increased rapidly to 3 cm in 60 s at 50 W. The blood loss and blood loss per transection area in Group A were significantly lower than those in Group B (18 (7-26) ml vs. 34 (19-57) ml, and 2.4 (2-3.1) ml/cm vs. 6.9 (3.2-8.3) ml/cm , respectively) (  < 0.05). The transection speed in Group A (2.6(1.9-3.8) cm /min) was significantly faster than that in Group B (1.7(1.1-2.2) cm /min) (  < 0.05). In this experimental model, the new water-cooled MW array-assisted liver resection (LR) has the potential advantage of less blood loss and rapid removal than the conventional LR.

Thermal, mechanical, and biocompatibility properties and cell behavior was assessed and compared to 100% collagen type I hydrogels to demonstrate their utility as a tissue model for 3D in vitro testing.Results A combination (i.e., containing both collagen 'C/KNT') hydrogel was more thermally stable than pure collagen hydrogels and resisted thermal degradation when incubated at a hyperthermic temperature of 47°C for heating durations up to 60 min with a higher melting temperature measured by DSC. An increase in the storage modulus was only observed with an increased collagen concentration rather than an increased KTN concentration; however, a change in ECM structure was observed with greater fiber alignment and width with an increase in KTN concentration. The C/KTN hydrogels, specifically 50/50 C/KTN hydrogels, also supported the growth and of fibroblasts and MDA-MB-231 breast cancer cells similar to those seeded in 100% collagen hydrogels.Conclusion This multi-protein C/KTN hydrogel shows promise for future studies involving thermal stress studies without compromising the 3D ECM environment or cell growth.The effects of chronic coffee consumption on the cardiovascular system are still under debate. Aortic stiffness, wave reflections, and central and peripheral blood pressure (BP) are milestone indicators of cardiovascular-risk. We sought to investigate the association between coffee and caffeine consumption, arterial stiffness, and central/peripheral BP. Aortic stiffness was evaluated via pulse wave velocity (PWV); wave reflections with the augmentation index (AIx);peripheral systolic BP (SBP), diastolic BP (DBP), and central BP (cSBP/cDBP) were non-invasively assessed. Coffee and caffeine consumption was ascertained using a questionnaire. A linear inverse relationship between coffee and caffeine consumption and arterial stiffness and central and peripheral BP was found.Light coffee and caffeine consumers showed β-coefficients for PWV-0.15, SBP-3.61, DBP-2.48, cSBP-3.21, and cDBP-2.18 (all p values less then 0.05).Present findings suggest that coffee and caffeine consumption is inversely associated with arterial stiffness and central and peripheral BP in a large population sample. Interventional prospective studies are needed to demonstrate the causal association. This study analyzed the potential diagnosis and therapeutic challenges of retroperitoneal schwannoma (RSs) in a specialized gynecology hospital. A retrospective review was performed in our hospital from 2000 to 2018. https://www.selleckchem.com/products/ipi-145-ink1197.html A literature search of RSs was conducted using PubMed database. 45 patients were identified (22 from our hospital and 23 from the literature review). The majority of patients presented asymptomatic (22/45). Among them, 25 cases were misdiagnosed as adnexal cysts, 13 uterine fibroids, 1 ovarian malignancy and 6 pelvic masses. Intraoperative exploration revealed that the masses were located in the retroperitoneal space. The median diameter was 6.2 cm (range 3.0-9.8 cm) in our hospital compared with 9.3 cm (6-15 cm) in literature review. Complete resection was performed in 37 patients and subtotal resection in 8 patients. The pathological results confirmed the diagnosis of benign schwannoma and no recurrence was found in the follow-up data. The preoperative diagnosis of RSs is difficult to make because of its nonspecific characteristics. In a specialized gynecology hospital, it is more important to differentiate the benign and malignant of mass before surgery. Surgical complete resection of tumor is recommended and recurrence is unusual after complete resection.

Underage motorcycle riding in Indonesia has long been and continues to be common among its citizens. This study aimed to analyse motorcycle risky behaviours associated with motorcycle accidents among adolescents in Jakarta metropolitan area. This is a cross-sectional study employing a self-report survey of 3880 students from 37 junior and senior high schools in the Jakarta metropolitan area, Indonesia, between April and June 2019. About 40% of the respondents reported that they ever involved in motorcycle accidents in the past 12 months. Speeding, using a mobile phone, drowsy driving, and wrong-way riding were significantly associated with motorcycle accidents. Further, red-light running, applying sudden brake, eating, smoking or drinking, listening to music, drunk driving and drowsy driving have an influence on the severity of motorcycle accidents. 91.3% of motorcycle drivers in our samples did not have a driving license, and approximately 39% of them had involved in motorcycle accidents. More stringent controls from parents, schools and the government are needed to inhibit motorcycle use by minors.
