INTRODUCTION: The Morel-Lavallée lesion is an infrequently described, post-traumatic closed de-gloving wound that results from separation of the skin and subcutaneous tissues from the underlying deep fascia as a result of shearing forces that tear perforating vessels and lymphatics. This condition is rare in children and to our knowledge it represents the youngest case of Morel-Lavallée lesion yet reported. PRESENTATION OF CASE: We report on a twelve-month-old girl who presented after a motor vehicle accident with a tender fluctuant mass of the back and buttocks...

The algal extracellular substances (AESs), mainly excreted in the lag and stationary phases, inhibited the algal growth and culture recycle. The AESs consisted of protein-like substances and saccharides, which restrained the algal lipid and protein biosynthesis. Moreover, the increasing reactive oxygen species and anti-oxidative enzymes caused by AESs led to the oxidative damage and suppressed the cell activity. The AESs affected the cells through two possible ways: one is the AESs adhered to the cell surfaces; another is the cells yielded signal molecules in response to the AESs...

BACKGROUND: Fetal growth restriction (FGR) is an unclearly defined condition described as a fetal weight which is too low in relation to gestational age. It is recognized in 10-15% of singleton pregnancies and can lead to severe complications, including stillbirth. To reduce the adverse fetal and neonatal outcomes, many medical interventions are being introduced by obstetricians. These, like all medical procedures, may induce further complications, such as preterm labor and its consequences...

BACKGROUND: The analysis of recent studies on plasmonic photothermal therapy (PPT) after intravenous administration of gold nanorods (GNRs) has demonstrated that the effectiveness of nanoparticle-assisted laser hyperthermia depends on a correct dosage strategy of nanoparticle administration. Accumulation of GNRs in tumor tissue dramatically increases the local heating of the tumor without damage to healthy tissues. However, the optimal doses of GNR intravenous injections (IVIs) for effective accumulation in tumors, and optimal protocols of PPT are not designed yet...

Hyalinizing trabecular tumor was first described by Carney et al. (1) in 1987 and is a rare benign tumor of the thyroid gland that shares some of the microscopic features of medullary and papillary thyroid carcinoma. Hyalinizing trabecular tumor derives from follicular cells, and it is characterized by an apparent trabecular pattern and intratrabecular hyalinization. In this study, we present the case of a 40-year-old female patient with thyroid gland nodules, whose ultrasound results, clinical behavior, and fine-needle aspiration biopsy results were suspicious; the pathology after thyroidectomy indicated hyalinizing trabecular tumor...

Preperitoneal lipomas are rare in clinical practice. Here we report an unexpected diagnosis of a giant preperitoneal fibrolipoma detected intraoperatively during laparoscopic cholecystectomy in a 56-year-old woman. The mass was excised and a histopathological examination confirmed fibrolipoma. No recurrence was found on follow-up. In the literature, there have been many cases with unexpected diagnoses during laparoscopy. Here, we present an incidental giant preperitoneal fibrolipoma, which was overlooked by ultrasound and physical examination, but was detected during laparoscopic cholecystectomy...

Samples were pretreated by ultrasound at 300 W and 28 kHz in three different solutions. The thermal degradation characteristics of the samples were then characterized via thermogravimetric, differential scanning calorimetry, and Fourier transform infrared analysis in a nitrogen environment. The characteristic of gas product release, the formation mechanisms of the main products, and the mechanistic basis for the effects of ultrasound on wood components were studied. The results showed that the gaseous products are the same with ultrasound pretreatment but the amounts are changed...

Nowadays, tumor hypoxia has become a more predominant problem for diagnosis as well as treatment of cancer due to difficulties in delivering chemotherapeutic drugs and their carriers to these regions with reduced vasculature and oxygen supply. In such cases, external physical stimulus-mediated drug delivery, such as ultrasound and magnetic fields, would be effective. In this work, the effect of simultaneous exposure of low-intensity pulsed ultrasound and static magnetic field on colon (HCT116) and hepatocellular (HepG2) carcinoma cell inhibition was assessed in vitro...
