Metabolic cold adaptation (MCA) is a controversial hypothesis suggesting that cold adapted species display an elevated metabolic rate (MR) compared to their warm climate relatives. Here we test for the presence of MCA within 65 species of drosophilid flies reared under common garden conditions. MR was measured at both 10 and 20°C for both sexes and data was analyzed in relation to the natural thermal environment of these species. We found considerable interspecific variation in MR ranging from 1.34 to 8.99 µW mg(-1) at 10°C...

Ion transport in plants is not only strictly regulated on a transcriptional level, but it is also regulated posttranslationally. Enzyme modifications such as phosphorylation provide rapid regulation of many plant ion transporters and channels. Upon exposure to high ammonium concentrations in the rhizosphere, the high-affinity AMmonium Transporters (AMT) in Arabidopsis thaliana are efficiently inactivated by phosphorylation to avoid toxic accumulation of cytoplasmic ammonium. External ammonium stimulates the phosphorylation of a conserved threonine in the cytosolic AMT1 C-terminus, which allosterically inactivates AMT1 trimers...

OBJECTIVE: Cortical excitability differs between treatment responders and nonresponders in new-onset epilepsy. Moreover, during the first 3 years of epilepsy, cortical excitability becomes more abnormal in nonresponders but normalizes in responders. Here, we study chronic active epilepsy, to examine whether cortical excitability continues to evolve over time, in association with epilepsy duration and treatment response. METHODS: We studied 28 normal subjects, 28 patients with moderately controlled epilepsy (≤4 seizures per year) and 40 patients with poorly controlled epilepsy (≥20 or more seizures per year)...

In recent years, versatile genetic tools have been developed and applied to a number of filamentous fungi of industrial importance. However, the existing techniques have limitations when it comes to achieve the desired genetic modifications, especially for efficient gene targeting. In this study, we used Aspergillus carbonarius as a host strain due to its potential as a cell factory, and compared three gene targeting techniques by disrupting the ayg1 gene involved in the biosynthesis of conidial pigment in A...

Hydrogen peroxide (H2O2) is becoming significant due to its extensive applications, so determination of H2O2 is very important topic in analytical chemistry. Metal-free "graphene alloy" - nitrogen (N) and sulfur (S) heteroatoms co-doped reduced graphene oxide (NS-rGO) was produced via a simple one-step thermal annealing procedure using a mixture of 5-amino-2-mercapto-1,3,4-thiadiazole (AMT) and graphene oxide (GO). The obtained metal-free NS-rGO composite showed better electrocatalytic activity toward the reduction of H2O2 compared with the reduced graphene oxide (rGO)...

The use of online crowdsourcing services like Amazon's Mechanical Turk (AMT) as a method of collecting behavioral data online has become increasingly popular in recent years. A growing body of contemporary research has empirically validated the use of AMT as a tool in psychological research by replicating a wide range of well-established effects that have been previously reported in controlled laboratory studies. However, the potential for AMT to be used to conduct spatial cuing experiments has yet to be investigated in depth...

BACKGROUND: Post-operative cognitive impairment is common in elderly patients following surgery for hip fracture, with undertreated pain being an important etiological factor. Non-opioid based analgesic techniques, such as nerve blocks, may help reduce the risk of cognitive complications. The aim of this study was to investigate whether receiving a fascia iliaca compartment block (FICB) as part of a pre-operative analgesic regime increased the odds of high post-operative abbreviated mental test scores (AMTS) when compared with conventional analgesia without a nerve block...

Autologous serum (AS) and amniotic membrane transplantation (AMT) are used in the treatment of several ocular surface diseases. AMT is associated with a surgical intervention. Surgery could be avoided by using eye drops prepared from an amniotic membrane homogenate (AMH) or amniotic membrane suspension (AMS). EGF, bFGF, IL-6 and IL-8 were detected in AMS. However, EGF and bFGF concentrations in AMS were about 1.7-17× lower than in AMH, and IL-6 and IL-8 could not be detected in AMH. 100 % AMS, 15 and 30 % AMH significantly decreased proliferation of human corneal epithelial cells (HCECs) compared to controls (p = <0...

BACKGROUND: Controlling antibiotic use in healthcare establishments limits their consumption and the emergence of bacterial resistance. AIM: To evaluate the efficiency of an innovative antibiotic stewardship strategy implemented over three years in a university hospital. METHODS: An antimicrobial multi-disciplinary team (AMT) [pharmacist, microbiologist and infectious disease specialist (IDS)] conducted a postprescription review. Specific coding of targeted antibiotics (including broad-spectrum β-lactams, glycopeptides, lipopeptides, fluoroquinolones and carbapenems) in the computerized physician order entry allowed recording of all new prescriptions...

Transcranial magnetic stimulation (TMS) of the primary motor cortex (M1) can be used to evaluate descending corticomotor influences on spinal reflex excitability through modulation of the Hoffman reflex (H-reflex). The purpose of this study was to characterize between-session reliability of cortical, spinal, and cortical-conditioned spinal excitability measures collected from the soleus muscle. Thirteen able-bodied young adult participants were tested over four sessions. Intraclass correlation coefficients were calculated to quantify between-session reliability of active motor threshold (AMT), unconditioned H-reflexes (expressed as a percentage of Mmax), and conditioned H-reflexes using short-latency facilitation (SLF) and long-latency facilitation (LLF)...

BACKGROUND: Medication errors continue to be a significant source of patient harm in the operating room with few concrete countermeasures. The organization and identification of medication syringes may have an impact on the commission of medication errors in anesthesia, so a team of physicians and designers at the University of Washington created the Anesthesia Medication Template (AMT) to define a formal way of organizing the anesthesia workspace. The purpose of this study is to assess the ability of the AMT to reduce perioperative medication errors by anesthesia providers...

BACKGROUND: Rh50 proteins belong to the family of ammonia permeases together with their Amt/MEP homologs. Ammonia permeases increase the permeability of NH3/NH4(+) across cell membranes and are believed to be involved in excretion of toxic ammonia and in the maintenance of pH homeostasis. RH50 genes are widespread in eukaryotes but absent in land plants and fungi, and remarkably rare in prokaryotes. The evolutionary history of RH50 genes in prokaryotes is just beginning to be unveiled...

Leucine-rich repeat kinase 2 (LRRK2) has been linked to familial and sporadic Parkinson's disease. However, it is still unresolved whether LRRK2 in dopaminergic (DAergic) neurons may or may not aggravate the phenotype. We demonstrate that knocking down (KD) the Lrrk gene by RNAi in DAergic neurons untreated or treated with paraquat (PQ) neither affected the number of DAergic clusters, tyrosine hydroxylase (TH) protein levels, lifespan nor locomotor activity when compared to control (i.e. TH/+) flies. KD transgenic Lrrk flies dramatically increased locomotor activity in presence of TH enzyme inhibitor alpha-methyl-para-tyrosine (aMT), whereas no effect on lifespan was observed in both fly lines...

The autobiographical memory test (AMT) is a widely used measure to assess the specificity of autobiographical memories. Reduced Autobiographical Memory Specificity (AMS) or increased overgeneralization of memories is considered as a cognitive hallmark of depression. Therefore, reduced AMS is the subject of much psychopathological research, and is a promising target for psychological interventions. Although considerable evidence has been gathered on the clinical relevance of reduced AMS over the past decades, studies on AMS have been mainly conducted in Western populations, and few have been conducted in Asian populations...
