Responses of insect herbivores and herbivory to habitat fragmentation: a hierarchical meta-analysis.

Loss and fragmentation of natural habitats can lead to alterations of plant-animal interactions and ecosystems functioning. Insect herbivory, an important antagonistic interaction is expected to be influenced by habitat fragmentation through direct negative effects on herbivore community richness and indirect positive effects due to losses of natural enemies. Plant community changes with habitat fragmentation added to the indirect effects but with little predictable impact.

Myrteae phylogeny, calibration, biogeography and diversification patterns: Increased understanding in the most species rich tribe of Myrtaceae.

Myrteae (c. 2500 species; 51 genera) is the largest tribe of Myrtaceae and an ecologically important groups of angiosperms in the Neotropics. Systematic relationships in Myrteae are complex, hindering conservation initiatives and jeopardizing evolutionary modelling.

Incidence of Endemic Burkitt Lymphoma in Three Regions of Mozambique.

Data on the burden and incidence of endemic Burkitt lymphoma (eBL) across Mozambique are scarce. We retrospectively retrieved information on eBL cases from reports of the three main hospitals of Mozambique: Maputo Central Hospital (MCH), Beira Central Hospital (BCH), and Nampula Central Hospital (NCH) between 2004 and 2014. For 2015, we prospectively collected information of new eBL cases attending these hospitals.

Epigenetic Signatures at the RUNX2-P1 and Sp7 Gene Promoters Control Osteogenic Lineage Commitment of Umbilical Cord-Derived Mesenchymal Stem Cells.

Wharton's Jelly mesenchymal stem cells (WJ-MSCs) are an attractive potential source of multipotent stem cells for bone tissue replacement therapies. However, the molecular mechanisms involved in their osteogenic conversion are poorly understood. Particularly, epigenetic control operating at the promoter regions of the two master regulators of the osteogenic program, RUNX2/P57 and SP7 has not yet been described in WJ-MSCs.

Single-unit analysis of the human posterior hypothalamus and red nucleus during deep brain stimulation for aggressivity.

OBJECTIVE Deep brain stimulation (DBS) of the posterior hypothalamus (PH) has been reported to be effective for aggressive behavior in a number of isolated cases. Few of these case studies have analyzed single-unit recordings in the human PH and none have quantitatively analyzed single units in the red nucleus (RN). The authors report on the properties of ongoing neuronal discharges in bilateral trajectories targeting the PH and the effectiveness of DBS of the PH as a treatment for aggressive behavior.

Polycomb PRC2 complex mediates epigenetic silencing of a critical osteogenic master regulator in the hippocampus.

During hippocampal neuron differentiation, the expression of critical inducers of non-neuronal cell lineages must be efficiently silenced. Runx2 transcription factor is the master regulator of mesenchymal cells responsible for intramembranous osteoblast differentiation and formation of the craniofacial bone tissue that surrounds and protects the central nervous system (CNS) in mammalian embryos. The molecular mechanisms that mediate silencing of the Runx2 gene and its downstream target osteogenic-related genes in neuronal cells have not been explored.

The chromatin modifying complex CoREST/LSD1 negatively regulates notch pathway during cerebral cortex development.

The development of the cerebral cortex is a dynamic and coordinated process in which cell division, cell death, migration, and differentiation must be highly regulated to acquire the final architecture and functional competence of the mature organ. Notch pathway is an important regulator of differentiation and it is essential to maintain neural stem cell (NSC) pool. Here, we studied the role of epigenetic modulators such as lysine-specific demethylase 1 (LSD1) and its interactor CoREST in the regulation of the Notch pathway activity during the development of the cerebral cortex.

Efficacy and Safety of Canagliflozin in Type 2 Diabetes Patients of Different Ethnicity.

Objective: To assess the efficacy and safety of the sodium glucose co-transporter 2 (SGLT2) inhibitor canagliflozin in patients of different ethnicities.

Design Setting And Patients: Post hoc analysis of data pooled from four randomized, placebo-controlled, phase 3 studies of adults with inadequately controlled type 2 diabetes mellitus (T2DM).

Interventions: Once daily oral canagliflozin 100 mg or 300 mg, or placebo.

Low-pressure cardiac tamponade: A case report.

A 57-year-old woman presented with a large idiopathic pericardial effusion with subsequent cardiac tamponade, in whom the intrapericardial pressure measured by pericardiocentesis was not elevated. The patient did not present with the classical clinical features of cardiac tamponade, requiring echocardiographic follow-up to make accurate diagnosis and treatment. This entity called low-pressure cardiac tamponade has been diagnosed anecdotally being an insidious condition that requires a high degree of suspicion.

Granulocyte colony-stimulating factor (G-CSF) upregulates β1 integrin and increases migration of human trophoblast Swan 71 cells via PI3K and MAPK activation.

Multiple cytokines and growth factors expressed at the fetal-maternal interface are involved in the regulation of trophoblast functions and placental growth, but the role of G-CSF has not been completely established. Based on our previous study showing that G-CSF increases the activity of matrix metalloproteinase-2 and the release of vascular endothelial growth factor in Swan 71 human trophoblast cells, in this work we explore the possible contribution of G-CSF to cell migration and the G-CSF-triggered signaling pathway. We found that G-CSF induced morphological changes on actin cytoskeleton consistent with a migratory cell phenotype.

Real-world evaluation of glycemic control among patients with type 2 diabetes mellitus treated with canagliflozin versus dipeptidyl peptidase-4 inhibitors.

Objective To evaluate glycemic control among patients with type 2 diabetes mellitus (T2DM) treated with canagliflozin (CANA) vs. dipeptidyl peptidase-4 (DPP-4) inhibitors. Methods Using integrated claims and lab data from a US health plan of commercial and Medicare Advantage enrollees, this matched-control cohort study assessed adult T2DM patients receiving treatment with CANA or DPP-4 inhibitors (1 April 2013-31 December 2013).

The Time Is Right for a New Classification System for Diabetes: Rationale and Implications of the β-Cell-Centric Classification Schema.

The current classification system presents challenges to the diagnosis and treatment of patients with diabetes mellitus (DM), in part due to its conflicting and confounding definitions of type 1 DM, type 2 DM, and latent autoimmune diabetes of adults (LADA). The current schema also lacks a foundation that readily incorporates advances in our understanding of the disease and its treatment. For appropriate and coherent therapy, we propose an alternate classification system.

Factors Associated With Delays in Seeking Medical Attention in Patients With ST-segment Elevation Acute Coronary Syndrome.

Methods: Prospective cohort study in consecutive patients with ST segment elevation infarction.

High-Resolution Faraday Rotation and Electron-Phonon Coupling in Surface States of the Bulk-Insulating Topological Insulator Cu_{0.02}Bi_{2}Se_{3}.

We have utilized time-domain magnetoterahertz spectroscopy to investigate the low-frequency optical response of the topological insulator Cu_{0.02}Bi_{2}Se_{3} and Bi_{2}Se_{3} films. With both field and frequency dependence, such experiments give sufficient information to measure the mobility and carrier density of multiple conduction channels simultaneously.

Regulation of Murine Ovarian Epithelial Carcinoma by Vaccination against the Cytoplasmic Domain of Anti-Müllerian Hormone Receptor II.

Anti-Müllerian hormone receptor, type II (AMHR2), is a differentiation protein expressed in 90% of primary epithelial ovarian carcinomas (EOCs), the most deadly gynecologic malignancy. We propose that AMHR2 may serve as a useful target for vaccination against EOC. To this end, we generated the recombinant 399-amino acid cytoplasmic domain of mouse AMHR2 (AMHR2-CD) and tested its efficacy as a vaccine target in inhibiting growth of the ID8 transplantable EOC cell line in C57BL/6 mice and in preventing growth of autochthonous EOCs that occur spontaneously in transgenic mice.

Recombinant vaccinia virus GLV-1h68 is a promising oncolytic vector in the treatment of cholangiocarcinoma.

Although early stage cholangiocarcinoma (CC) can be cured by surgical extirpation, the options for treatment of advanced stage CC are very few and suboptimal. Oncolytic virotherapy using replication-competent vaccinia virus (VACV) is a promising new strategy to treat human cancers. The ability of oncolytic VACV GLV-1h68 to infect, replicate in, and lyse three human CC cell lines was assayed in vitro and in subcutaneous flank xenografts in athymic nude mice.
