Environmental Load Evaluation of Reuse Parts for Automobiles

Abstract Reuse parts are parts removed from scrap automobiles that can be still used. In general, reuse parts reduce not only the cost for replacement of failed parts but also the environmental load. This study quantitatively evaluates environmental loads, such as the amount of CO2 emission during the production of brand new parts, in order to quantify the beneficial effect of the reuse parts. The amount of CO2 emission can be calculated from the power consumption and operating time of each tool and machine employed. Reuse parts generate 0.62 kg of CO2 per automobile when produced, which corresponds to 1,212 kg per year. However, the amount of CO2 emitted from scrapping automobiles without producing new replacement parts is 3,063 kg per year. Therefore, the production of replacement parts emits three times less CO2 than scrapping

LIPUS effect on osteoarthritic TMJs

The aim of this study was to assess the effect of low-intensity pulsed ultrasound (LIPUS) application on rat temporomandibular joints (TMJs) with early-stage of osteoarthritis-like conditions induced by mechanical overloading. Fifteen-week-old male Wistar rats were divided into two experimental groups and a control group (n = 10 each). Both TMJs of all rats in one experimental group were subjected to mechanical overloading for 5 d, and those in the other experimental group were exposed to LIPUS for 20 min/d after overloading. Condyles were assessed using micro-computed tomography, histology and histomorphometry. LIPUS treatment attenuated cartilage degeneration, decreased the number of osteoclastic cells and restored the expression of aggrecan after an initial decrease induced by mechanical overloading. These results indicate that LIPUS may have a protective effect on the early progression of TMJ osteoarthritis

Expectant management of a herniated amniotic sac presenting as silent uterine rupture: a case report and literature review.

Foetal membranes bulging into the abdominal cavity is a unique initial manifestation of silent or complete uterine rupture during pregnancy. Since silent uterine rupture has potential risk for complete uterine rupture, which leads to acute life-threatening complications for both the mother and baby, it is difficult to determine whether to manage expectantly or surgically, including repair of the uterine wall or termination of the pregnancy, especially in the early second trimester. We present here a case of a herniated amniotic sac with overstretched uterine wall of the fundus presenting as silent uterine rupture, which was incidentally detected on routine ultrasonography at 18 weeks' gestation in a 38-year-old primigravida with a history of myomectomy for diffuse uterine leiomyomatosis. Magnetic resonance imaging examination revealed that the myometrium thickness was fully maintained at the site of the foetal membranes ballooning. The pregnancy was therefore managed expectantly and continued to successful delivery at 30 weeks' gestation. The precise assessment of the uterine wall may be essential to manage a herniated amniotic sac presenting as silent uterine rupture and to optimise the outcome of the pregnancy. We review all cases of a herniated amniotic sac out of focally overstretched uterine wall before 34 weeks' gestation

Peritoneal Recurrence of Initially Controlled Hepatocellular Carcinoma after Living Donor Liver Transplantation

It is well known that the presence of end-stage liver disease increases the risk of developing hepatocellular carcinoma (HCC). Liver transplantation (LT) for patients within the Milan criteria has become a standard treatment for HCC in most developed centers worldwide. However, a major cause of death in cirrhotic patients with HCC after transplantation is tumor recurrence, including peritoneal recurrences, which develops rarely but presents a significant problem with regard to their management. Our experience includes two cases with HCC within the Milan criteria of peritoneal recurrences after living donor LT. Both patients had interventions for HCC in their medical history before LT, and we propose that these might have been a possible cause of the HCC peritoneal recurrence
