The treatment of lymphatic malformations (LMs) represents a great clinical challenge. The present study reported on the treatment of 68 infants with cervical macrocystic LMs using surgical resection. The cases were retrospectively analyzed. All patients underwent pre-operative ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) examinations. The surgery was performed under general anesthesia with endotracheal intubation. Ultrasonograms showed that 24 cases were monolocular, 44 were multilocular, 16 had no echo, 20 had a uniform low-level echo and 32 had a non-uniform low-level echo...

Sexual selection is an intense evolutionary force, which operates through competition for the access to breeding resources. There are many cases where male copulatory success is highly asymmetric, and few males are able to sire most females. Two main hypotheses were proposed to explain this asymmetry: "female choice" and "male dominance". The literature reports contrasting results. This variability may reflect actual differences among studied populations, but it may also be generated by methodological differences and statistical shortcomings in data analysis...

Blood coagulation is a protective response that prevents excessive bleeding upon blood vessel injury. We investigated the relationship between coagulation and the resolution of inflammation and infection by lipid mediators (LMs) through metabololipidomics-based profiling of human whole blood (WB) during coagulation. We identified temporal clusters of endogenously produced prothrombotic and proinflammatory LMs (eicosanoids), as well as specialized proresolving mediators (SPMs). In addition to eicosanoids, a specific SPM cluster was identified that consisted of resolvin E1 (RvE1), RvD1, RvD5, lipoxin B4, and maresin 1, each of which was present at bioactive concentrations (0...

BACKGROUND: The Dual Energy X-Ray Absorptiometry (DXA) is the gold standard for measuring BMD and bone mineral content (BMC). In general, DXA is ideal for pediatric use. However, the development of specific standards for particular geographic regions limits its use and application for certain socio-cultural contexts. Additionally, the anthropometry may be a low cost and easy to use alternative method in epidemiological contexts. The goal of our study was to develop regression equations for predicting bone health of children and adolescents based on anthropometric indicators to propose reference values based on age and sex...

INTRODUCTION: Although rare, cases of abdominal sarcomatosis (AS) after laparotomy/laparoscopic interventions for uterine smooth muscle tumors of uncertain malignant potential (STUMP) have been reported. PRESENTATION OF CASE: We describe a rare case of diffuse abdominal sarcomatosis in a patient that some year earlier had undergone myomectomy for a suspected uterine myoma, which was histologically proven to be a STUMP. Once the patient was admitted at our Department, she underwent a diagnostic laparoscopy that confirmed a condition of peritoneal sarcomatosis disseminated through the entire abdomen, and then a laparotomic total hysterectomy, bilateral salpingo-oophorectomy, and total omentectomy, achieving a complete cytoreduction...

Gallid herpesvirus 2 (GaHV-2) continuously evolves, which reduces the effectiveness of existing vaccines. To construct new GaHV-2 candidate vaccines, LMS, which is a virulent GaHV-2 field strain isolated from diseased chicken flocks in Southwest China in 2007, was modified such that both copies of its meq oncogene were partially deleted. The resulting virus, i.e., rMSΔmeq, was characterized using PCR and sequencing. To evaluate the safety and protective efficacy of rMSΔmeq, specific pathogen-free (SPF) chickens were inoculated with 2000 plaque forming units (pfu) and 20,000pfu of rMSΔmeq immediately after hatching...

An electro-hydraulic shaking table (EHST) is an essential experimental facility to simulate in real-time actual vibration situations. An adaptive controller combined with off-line compensators is proposed to improve the acceleration frequency bandwidth and tracking accuracy of a six-degree-of-freedom (6-DOF) EHST. A servo controller has been employed to implement acceleration closed-loop and coordinate control of the 6-DOF EHST. A recursive extended least-squares algorithm is employed to identify acceleration closed-loop transfer functions and a zero-phase-error tracking controller is used to design off-line inverse model compensators using the identified transfer functions...

BACKGROUND: Chronic rhinosinusitis (CRS) is a commonly observed sequela after radiation therapy to the paranasal sinuses. The histopathologic features of radiation-induced CRS have yet to be determined and may have major implications in disease management. METHODS: A structured histopathology report was utilized to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). Histopathology variables, Lund-Mackay score (LMS), and 22-item Sino-Nasal Outcome Test (SNOT-22) scores were compared among patients with radiation-induced CRS (CRSr), CRS without nasal polyps (CRSsNP), and CRS with nasal polyps (CRSwNP)...

We studied the mechanisms of sensitivity of soft tissue sarcoma cells to alkylating agent temozolomide. The mechanisms of tumor cell sensitivity to temozolomide are complex and are determined by not only the level of O6-methylguanine-DNA-methyltransferase (MGTM) expression, but also activity of oncosuppressor protein p53. A-673 Ewing's sarcoma cells were found to be the most sensitive to temozolomide, whereas temozolomide-treated SK-LMS-1 leiomyosarcoma cells exhibited signs of cell aging.

An endogenous metabolite of 17β-estradiol, 2-methoxyestradiol (2-ME), has affinity for estrogen receptors. This compound was reported to be a promising antitumor drug due to its anti-proliferative effects on a wide range of tumor cell types. Numerous previous studies have been performed to evaluate the cytotoxic effects of 2-ME on tumor cell lines in following the induction of G2/M cell cycle arrest and subsequent apoptosis. Uterine leiomyosarcoma (ULMS) is a relatively rare malignant smooth muscle cell tumor that develops in the uterus muscle layer...
