Aquatic macroinvertebrates play a crucial role in freshwater ecosystems, but their diversity remains poorly known, particularly in the tropics. This "taxonomic void" represents limits our understanding of biodiversity patterns and processes in freshwater ecosystems, and the scale at which they operate. We used DNA barcoding to estimate lineage diversity (and the diversity of unique haplotypes) in 224 specimens of freshwater macroinvertebrates at a small spatial scale within the Panama Canal Watershed...

In angiosperm self-incompatibility systems, pollen with an allele matching the pollen recipient at the self-incompatibility locus is rejected. Extreme allelic polymorphism is maintained by frequency-dependent selection favoring rare alleles. However, two challenges limit the spread of a new allele (a tightly linked haplotype in this case) under the widespread "collaborative non-self recognition" mechanism. First, there is no obvious selective benefit for pollen compatible with non-existent stylar...

OBJECTIVE: This study aims to explore the role of GNAS in accelerating the progression of osteoporosis by inhibiting osteogenesis of BMSCs by the Wnt pathway. PATIENTS AND METHODS: GNAS levels in OP tissues and BMSCs undergoing osteogenesis for different time points were detected. Regulatory effects of GNAS on osteogenesis-related gene expressions, ALP activity, capability of mineralization, and activation of the Wnt pathway in BMSCs were assessed through a series of functional experiments. At last,...

OBJECTIVE: Osteogenic differentiation of bone marrow stromal stem cells (BMSCs) is beneficial to the treatment of osteoarthritis (OA). Lnc-RNA BLACAT1 involves in occurrence and development of various diseases. However, the role of Lnc-RNA BLACAT1 in BMSCs differentiation under inflammation remains unclear. MATERIALS AND METHODS: Rat BMSCs were isolated and randomly divided into control group and inflammation group (addition of IL-6). The inflammation group was further divided into BLACAT1 siRNA...

Background: Bronchial occlusion using an endobronchial Watanabe spigot (EWS) is reportedly effective for intractable bronchopleural fistula. Here, we describe a rapid and easy method for bronchial occlusion using a guide sheath (GS) and curette. Methods: Thirty consecutive patients who underwent bronchial occlusion under mild sedation between October 2014 and February 2018 were enrolled. The devices used were a flexible bronchoscope (BF-1T260 or BF-1TQ290), GS (SG-201C; with 30 mm of the...

Background: Research is increasingly raising concerns regarding the negative consequences of children’s use of screens. Summary: This article reviews the literature on the benefits and risks of screen time with attention to explaining possible reasons that children with autism are more at risk for the negative effects of screen time. Based on the science of learning literature, a framework for choosing appropriate digital media for children with autism is described. The 3-component framework considers...

There is a great controversy about hormonal replacement therapy in women among the members of the scientific community. Cancer survivors have sometimes had their ovary function totally or partially destroyed, thus affecting their development and quality of life. In this study, we were looking for adverse effects caused, eventually, by estroprogestative therapy in a cohort of supplemented survivors. The occurrence of breast cancer was our main concern. Ours is a retrospective study based on the clinical...
