Functionally distinct assembly of vascular plants colonizing alpine cushions suggests their vulnerability to climate change.

Ann Bot 2018 Dec 12. Epub 2018 Dec 12.

Institute of Botany, The Czech Academy of Sciences, Průhonice, Czech Republic.

Background And Aims: Alpine cushion plants can initially facilitate other species during ecological succession, but later on can be negatively affected by their development, especially when beneficiaries possess traits allowing them to overrun their host. This can be reinforced by accelerated warming favouring competitively strong species over cold-adapted cushion specialists. However, little empirical research has addressed the trait-based mechanisms of these interactions. Read More

Efficacy and predictors of response to inhaled corticosteroid treatment for chronic cough.

Korean J Intern Med 2018 Dec 13. Epub 2018 Dec 13.

Lung Research Institute of Hallym University College of Medicine, Chuncheon, Korea.

Background/aims: Inhaled corticosteroids (ICS) are a treatment of choice for eosinophilic airway diseases, but their efficacy for other causes of chronic cough is controversial.

Methods: We conducted a prospective observational study to determine the ICS efficacy and clinical predictors of response to ICS in patients with upper airway cough syndrome (UACS) or unexplained chronic cough (UCC). Sixty-eight patients with UACS and 33 patients with UCC (duration of cough ≥ 8 weeks) were treated with ICS: 250 µg of fluticasone propionate or 400 µg of budesonide twice a day at physician's discretion.

Gene expression is implicated in the ability of pikas to occupy Himalayan elevational gradient.

PLoS One 2018 12;13(12):e0207936. Epub 2018 Dec 12.

Department of Biology, Stanford University, Stanford, California, United States of America.

Species are shifting their ranges due to climate change, many moving to cooler and higher locations. However, with elevation increase comes oxygen decline, potentially limiting a species' ability to track its environment depending on what mechanisms it has available to compensate for hypoxic stress. Pikas (Family Ochotonidae), cold-specialist small mammal species, are already undergoing elevational range shifts. Read More

Storage of aerobic granular sludge embedded in agar and its reactivation by real wastewater.

J Water Health 2018 Dec;16(6):958-969

School of Architectural and Surveying & Mapping Engineering, Jiangxi University of Science and Technology, Ganzhou 341000, Jiangxi, China E-mail:

Aerobic granular sludge (AGS) was preserved using an agar embedding method to maintain its stability. No obvious damage was imposed on the granular appearance during 30 days of cold and dry storage, but the granular microstructure had an uneven surface with a large number of holes. The results were consistent with the extinction of microbial communities and the monitored consumption of extracellular polymeric substances, in which granular specific oxygen utilization rate and mixed liquor volatile suspended solids/mixed liquor suspended solids ratio, respectively, decreased by 72.

Biology Department, Concordia University, 7141, Sherbrooke, W. Montreal (Quebec), H4B 1R6, Canada.

Background: Members of the Early Salt Induced 3 (Esi3/RCI2/PMP3) gene family in plants have been shown to be induced in response to both biotic and abiotic stresses and to enhance stress tolerance in both transgenic plants and Saccharomyces cerevisiae. Esi3 was first identified as a salt stress induced gene in the salt tolerant wild wheat grass, Lophopyrum elongatum, and subsequently homologous genes in many other species were found to be members of the gene family. These include Arabidopsis thaliana and Oryza sativa where they are referred to as Rare Cold Inducible 2 (RCI2), and Zea mays where they are referred to as Plasma Membrane Protein 3 (PMP3). Read More

MicroRNAs (miRNAs) are endogenous small non-coding RNAs of about 20 - 24 nt, known to play important roles in plant development and adaptation. There is an accumulating evidence showing that the expressions of certain miRNAs are altered when grafting, an agricultural practice commonly used by farmers to improve crop tolerance to biotic and abiotic stresses. Bottle gourd is an inherently climate-resilient crop compared to many other major cucurbits, including watermelon, rendering it one of the most widely used rootstocks for the latter. Read More

Impact of Acute Dietary Nitrate Supplementation during Exercise in Hypertensive Women.

Med Sci Sports Exerc 2018 Dec 5. Epub 2018 Dec 5.

Department of Kinesiology, Kansas State University, Manhattan, KS.

Introduction: the aim of the current investigation was to examine if dietary nitrate supplementation would improve vascular control in hypertensive post-menopausal women (PMW). We tested the hypotheses that acute dietary nitrate supplementation would 1) significantly decrease arterial blood pressure (BP) at rest and during exercise; 2) increase limb blood flow during steady-state exercise; and 3) improve functional sympatholysis during steady-state (SS) exercise.

Methods: ten hypertensive PMW underwent a randomized, double-blind placebo-controlled trial with a nitrate-rich (NR) or nitrate poor (NP) supplement. Read More

Development of a simplified Cold Intolerance Symptom Severity questionnaire in patients with peripheral nerve injury.

Int J Rehabil Res 2018 Dec 10. Epub 2018 Dec 10.

Istituti Clinici Scientifici Maugeri, IRCCS, Bioengineering Unit of Veruno Institute (NO) Italy.

The aim of this study was to analyse the Cold Intolerance Symptom Severity (CISS) questionnaire in its Italian validated version, using Rasch analysis, to gain insights for a possible refinement of the questionnaire. The CISS was administered to a convenience sample of 96 consecutively recruited outpatients with upper limb peripheral nerve injury. Data were analysed using Rasch analysis. Read More

Taboo gesticulations as a response to pain.

Scand J Pain 2018 Dec 7. Epub 2018 Dec 7.

School of Psychology, Keele University, Keele, Staffordshire, UK.

Background and aims Prior research indicates that swearing increases pain tolerance and decreases pain perception in a cold pressor task. In two experiments, we extend this research by testing whether taboo hand gesticulations have a similar effect. Methods Study 1 focused on males and females who, across two trials, submerged an extended middle finger (taboo) and an extended index finger (control) in ice water until discomfort necessitated removal.

The depot-specific and essential roles of CBP/p300 in regulating adipose plasticity.

J Endocrinol 2019 Feb;240(2):257-269

Naomi Berrie Diabetes Center, Department of Pathology and Cell Biology, Vagelos College of Physicians and Surgeons, Columbia University, New York, New York, USA.

Fat remodeling has been extensively explored through protein deacetylation, but not yet acetylation, as a viable therapeutic approach in the management of obesity and related metabolic disorders. Here, we investigated the functions of key acetyltransferases CBP/p300 in adipose remodeling and their physiological effects by generating adipose-specific deletion of CBP (Cbp-AKO), p300 (p300-AKO) and double-knockout (Cbp/p300-AKO) models. We demonstrated that Cbp-AKO exhibited marked brown remodeling of inguinal WAT (iWAT) but not epididymal WAT (eWAT) after cold exposure and that this pattern was exaggerated in diet-induced obesity (DIO).

Use of a Qualification Phantom for PET Brain Imaging in a Multicenter Consortium: A Collaboration Between the Pediatric Brain Tumor Consortium and the SNMMI Clinical Trials Network.

J Nucl Med 2018 Dec 7. Epub 2018 Dec 7.

Children's Hospital Boston, United States.

The purpose of this study was to assess image quality and quantitative brain PET across a multi-center consortium. All academic centers and children's hospitals in the Pediatric Brain Tumor Consortium (PBTC) scanned a phantom developed by the Society of Nuclear Medicine and Molecular Imaging Clinical Trials Network (SNMMI CTN) for the validation of brain PET studies associated with clinical trials. The phantom comprises 2 separate, fillable sections: a resolution/uniformity section and a clinical simulation section. Read More
