Global climate change and acquired resistance to insecticides are threats to world food security. Drosophila suzukii, a devastating invasive pest in many parts of the world, causes substantial economic losses to fruit production industries, forcing farmers to apply broad-spectrum insecticides frequently. This could lead to the development of insecticide resistance. We determined the Lethal Concentration50 (median lethal concentration) values of zeta-cypermethrin, spinosad, and malathion insecticides against D...

As a de-ubiquitin enzyme, ubiquitin C-terminal hydrolase (UCH)-L1 has been shown to be overexpressed in several human cancers. However, the function of UCH-L1 in invasion of breast cancers is still unclear. Here we report that the expression of UCH-L1 is significantly higher in cancer cells with higher invasive ability. While ectopic UCH-L1 expression failed to alter cell proliferation in MCF-7 cells, it caused a significant upregulation of cellular invasion. Furthermore, siRNA mediated knockdown of UCH-L1 led to suppression of invasion in UCH-L1 overexpressing MCF-7 cells...

The multifunctional SET/I2PP2A protein is known to be overexpressed in head and neck squamous cell carcinoma. However, SET has been reported to have apparently conflicting roles in promoting cancer cell survival under oxidative stress conditions and preventing invasion and metastasis, complicating efforts to understand the contribution of SET to carcinogenesis. In the present study, we overexpressed SET in a spontaneously immortalized oral keratinocyte cell line (NOK-SI SET) and demonstrated that SET up-regulation alone was sufficient to transform cells...

Osteosarcoma (OS) is one of the most common bone malignancies and occurs almost exclusively in children and adolescents. This study aimed to explore the role of lncRNA maternally expressed gene 3 (MEG3) in OS cells growth and metastasis, and to uncover the possible underlying mechanism. In this study, the expressions of MEG3 in five OS cell lines (MG63, OS-732, SaOS, G292, and 143B) and in a human osteoblast cell line hFOB1.19 were measured by qRT-PCR analysis. The expressions of MEG3, miR-127 and ZEB1 in OS-732 cells were overexpressed or suppressed by transfection...

Functional endoscopic sinus surgery (FESS) has considerably evolved over the past 20 years while minimally-invasive surgery also applies to sinus procedures. Development of new technologies combined with better knowledge of risks has allowed surgeons to achieve improved results in their FESS indications. One of the most difficult areas to visualize using the exclusive endoscopic approach is still the anterior recess of the maxillary sinus. Hence, external approaches, such as the Caldwell-Luc procedure, are still used by many surgeons to ensure visual control of this area in diseases such as fungal balls, mucoceles, inverted papilloma and other tumors...

OBJECTIVES: Minimally invasive plate osteosynthesis (MIPO) is one of the most recent fixation techniques that embody the concept of biological osteosynthesis. Several studies evaluating MIPO in dogs have been published in the recent years. However, there are few clinical reports of MIPO in cats and no description of the surgical approaches. The purpose of our study was to describe the safe corridors for plate insertion in cats using the MIPO technique. METHODS: The surgical approaches for the humerus, radius-ulna, femur and tibia were developed after reviewing the described techniques and surgical approaches for MIPO in dogs, while considering any relevant anatomical difference between dogs and cats...

It is argued that shortcomings of certain approaches to breath analysis research based on superficial interpretation of non-quantitative data are inadvertently inhibiting the progression of non-invasive breath analysis into clinical practice. The objective of this perspective is to suggest more clinically profitable approaches to breath research. Thus, following a discourse on the challenges and expectations in breath research, a brief indication is given of the analytical techniques currently used for the analysis of very humid exhaled breath...

Long non-coding RNA MEG3 has been identified as a tumor suppressor which plays important roles in tumorigenesis; however, its potential role in breast cancer has not been fully examined. Here, we showed that MEG3 was downregulated in breast cancer tissues and cell lines. Overexpression of MEG3 inhibited breast cancer cell proliferation and invasion, suggesting that MEG3 played an important role in breast cancer progression and metastasis. Moreover, MEG3 upregulation caused marked inhibition of angiogenesis-related factor expression...

The main goal of intensive care medicine is helping patients survive acute threats to their lives, while preserving and restoring life quality. Because of medical advancements, it is now possible to sustain life to an extent that would previously have been difficult to imagine. However, the goals of medicine are not to preserve organ function or physiological activity but to treat and improve the health of a person as a whole. When dealing with medical futilities, physicians and other members of the care team should be aware of some ethical principles...

PURPOSE: Histological confirmation of endometrial cancer by dilatation/curettage (D/C) in women with postmenopausal bleeding (PMB) can be challenging due to anesthesiological and/or surgical risks. Thus, less invasive methods for diagnostics are required to identify patients with minimal risk for endometrial cancer (EC) to avoid unnecessary surgical intervention. The objective of this single-center cohort study was to assess the diagnostic validity of transvaginal ultrasound (TVUS) measurements of endometrial thickness (ET) in patients with PMB for the detection of EC...
