A recent study reported that histone lysine specific demethylase 1 (LSD1, KDM1A) is overexpressed in endometrioid endometrial carcinoma (EEC) and associated with tumor progression as well as poor prognosis. However, the physiological function and mechanism of LSD1 in endometrial cancer (EC) remains largely unknown. In this study, we demonstrate that β-estradiol (E2) treatment increased LSD1 expression via the GPR30/PI3K/AKT pathway in endometrial cancer cells. Both siGPR30 and the PI3K inhibitor LY294002 block this effect...

Salvatore Chirumbolo, Geir Bjørklund
In this article the Proteasome, Endoplasmic Reticulum and Mitochondria (PERM) hypothesis is discussed. The complex machinery made by three homeostatic mechanisms involving the proteasome (P), endoplasmic reticulum (ER) and mitochondria (M) is addressed in order to elucidate the beneficial role of many xenobiotics, either trace metals or phytochemicals, which are spread in the human environment and in dietary habits, exerting their actions on the mechanisms underlying cell survival (apoptosis, cell cycle regulation, DNA repair and turnover, autophagy) and stress response...

Edible insects are gaining more and more attention as a sustainable source of animal protein for food and feed in the future. In Belgium, some insect products can be found on the market, and consumers are sourcing fresh insects from fishing stores or towards traditional markets to find exotic insects that are illegal and not sanitarily controlled. From this perspective, this study aims to characterize the microbial load of edible insects found in Belgium (i.e., fresh mealworms and house crickets from European farms and smoked termites and caterpillars from a traditional Congolese market) and to evaluate the efficiency of different processing methods (blanching for all species and freeze-drying and sterilization for European species) in reducing microorganism counts...

Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

Early and midgestational decidua of mice genetically ablated for expression of the natural killer (NK) cell natural cytotoxicity receptor (NCR; Ncr1(Gfp/Gfp) mice) shows restricted angiogenesis and atypically small uterine (u)NK cells . We hypothesized that NCR1 inactivation disturbs maturation and angiokine production by uterine natural killer (uNK) cells. Using histological and morphometric approaches, we observed that Ncr1(Gfp/Gfp) but not control C57BL/6 (B6) implantation sites sustain immature, non-granulated uNK cells into midpregnancy...

We report the feasibility of using reduced graphene oxide (RGO) as a cost-effective and high performance cathode material for sodium-ion batteries (SIBs). Graphene oxide is synthesized by a modified Hummers' method and reduced using a solid-state microwave irradiation method. The RGO electrode delivers an exceptionally stable discharge capacity of 240 mAh g(-1) with a stable long cycling up to 1000 cycles. A discharge capacity of 134 mAh g(-1) is obtained at a high current density of 600 mA g(-1), and the electrode recovers a capacity of 230 mAh g(-1) when the current density is reset to 15 mA g(-1) after deep cycling, thus demonstrating the excellent stability of the electrode with sodium de/intercalation...

The topology of many real complex networks has been conjectured to be embedded in hidden metric spaces, where distances between nodes encode their likelihood of being connected. Besides of providing a natural geometrical interpretation of their complex topologies, this hypothesis yields the recipe for sustainable Internet's routing protocols, sheds light on the hierarchical organization of biochemical pathways in cells, and allows for a rich characterization of the evolution of international trade. Here we present empirical evidence that this geometric interpretation also applies to the weighted organization of real complex networks...

The Activin/Nodal/TGF-β signaling pathway plays a major role in maintaining mouse epiblast stem cells (EpiSCs). The EpiSC-maintaining medium, which contains Activin A and bFGF, induces differentiation of mouse embryonic stem cells (ESCs) to EpiSCs. Here, we show that Activin A also has an ability to efficiently propagate ESCs without differentiation to EpiSCs when combined with a MEK inhibitor PD0325901. ESCs cultured in Activin+PD retained high-level expression of naive pluripotency-related transcription factors...

"Aqua materials" that contain water as their major component and are as robust as conventional plastics are highly desirable. Yet, the ability of such systems to withstand harsh conditions, for example, high pressures typical of industrial applications has not been demonstrated. We show that a hydrogel-like membrane self-assembled from an aromatic amphiphile and colloidal Nafion is capable of purifying water from organic molecules, including pharmaceuticals, and heavy metals in a very wide range of concentrations...

Periprosthetic joint infection (PJI) of the hip can be difficult to treat and can lead to a number of problems including: i) severe functional decline of the hip joint and ii) increasing financial burden for patients due to long treatment periods and the need for repeated surgical interventions. Because there is risk of inadequate control of infection or relapse of a preexisting infection following the treatment of PJI through surgery, it is important to closely observe clinical symptoms such as systemic fever...

Prevalence of hepatitis C virus (HCV) infection is high in patients with end-stage renal dysfunction, including patients undergoing hemodialysis (HD). The HCV infection itself can cause glomerulonephritis and puts individuals at increased risk of developing end-stage renal disease; fortunately, successful HCV eradication sometimes restore HCV-related renal dysfunction. Moreover, the prognosis of dialysis patients infected with HCV is significantly worse and the renal allograft survival in HCV-infected patients is also worse than in dialysis patients without HCV infection...

This study investigated whether a yoga exercise intervention influenced the sustained attention and discrimination function in children with ADHD. Forty-nine participants (mean age = 10.50 years) were assigned to either a yoga exercise or a control group. Participants were given the Visual Pursuit Test and Determination Test prior to and after an eight-week exercise intervention (twice per week, 40 min per session) or a control intervention. Significant improvements in accuracy rate and reaction time of the two tests were observed over time in the exercise group compared with the control group...

Bronchial inflammation contributes to a sustained elevation of airway hyperresponsiveness (AHR) in asthma. Conversely, omega-3 fatty acid derivatives have been shown to resolve inflammation in various tissues. Thus, the effects of docosapentaenoic acid monoacylglyceride (MAG-DPA) were assessed on inflammatory markers and reactivity of human distal bronchi as well as in a cultured model of guinea pig tracheal rings. Human bronchi were dissected and cultured for 48 h with 10 ng/mL TNF-α or IL-13. Guinea pig tracheas were maintained in organ culture for 72 h which was previously shown to trigger spontaneous AHR...

BACKGROUND: Pramipexole (PPX), a non-ergot dopamine receptor agonist, is a first-line treatment for Parkinson's disease (PD). A critical dose level above which a better benefit-to-harm ratio exists has not been examined. METHODS: Chinese PD patients (n=464) were retrospectively analyzed by PPX maintenance dose, PD stage, combined levodopa dose, and baseline tremor contribution. The sum score of Baseline Activities of Daily Living (part II) and Motor Examination (III) of the Unified Parkinson's Disease Rating Scale (UPDRS II+III) was used as a covariate for final score adjustment...
