Loss of function of the carbon catabolite repressor CreA leads to low but inducer-independent expression from the feruloyl esterase B promoter in Aspergillus niger

Author(s): Reijngoud J; Arentshorst M; Ruijmbeek C; Reid I; Alazi ED; Punt PJ; Tsang A; Ram AFJ;

Objective: With the aim to decipher the mechanisms involved in the transcriptional regulation of feruloyl esterase encoded by faeB, a genetic screen was performed to isolate A. niger mutants displaying inducer-independent expression from the faeB promoter. Result: PfaeB-amdS and PfaeB-lux dual reporter strains were constructed and used to isolate trans-a ...

Genetic Characterization of Mutations Related to Conidiophore Stalk Length Development in Aspergillus niger Laboratory Strain N402

Author(s): Demirci E; Arentshorst M; Yilmaz B; Swinkels A; Reid ID; Visser J; Tsang A; Ram AFJ;

Aspergillus niger is an important filamentous fungus in industrial biotechnology for the production of citric acid and enzymes. In the late 1980s, the A. niger N400/NRRL3 strain was selected for both fundamental and applied studies in relation to several processes including gluconic acid and protein production. To facilitate handling of A. niger, the N400 ...

Individuals With Mild Cognitive Impairment and Alzheimer's Disease Benefit From Audiovisual Speech Cues and Supportive Sentence Context

Author(s): Alexandre Chauvin

Purpose Speech perception in noise becomes difficult with age but can be facilitated by audiovisual (AV) speech cues and sentence context in healthy older adults. However, individuals with Alzheimer's disease (AD) may present with deficits in AV integration, potentially limiting the extent to which they can benefit from AV cues. This study investigate ...

Neurobehavioral, neurochemical and synaptic plasticity perturbations during postnatal life of rats exposed to chloroquine in-utero

Author(s): Olajide OJ; Alliy ZO; Ojo DO; Osinubi OO; Bello SO; Ibrahim FE; Adukwu FO; Abikoye TO; Gbadamosi IT; Mutholib NY; Bamisi O; Ajiboye OJ; Okesina AA; Alli-Oluwafuyi A; Oyewole AL; Nafiu AB; Akinola O;

Despite reports that quinoline antimalarials including chloroquine (Chq) exhibit idiosyncratic neuropsychiatric effects even at low doses, the drug continues to be in widespread use during pregnancy. Surprisingly, very few studies have examined the potential neurotoxic action of Chq exposure at d ...

Anxiety-like behavior in female mice is modulated by STAT3 signaling in midbrain dopamine neurons

Author(s): Fernandes MF; Lau D; Sharma S; Fulton S;

The central signaling actions of cytokines are mediated by signal transducer and activator of transcription (STAT3). STAT3 activation plays a pivotal role in the behavioral responses to the adiposity hormone leptin, including in midbrain dopamine (DA) neurons where it mediates the influence of leptin to diminish physical activity and running reward in mal ...

How cerebral cortex protects itself from interictal spikes: The alpha/beta inhibition mechanism

Author(s): Pellegrino G; Hedrich T; Sziklas V; Lina JM; Grova C; Kobayashi E;

Interactions between interictal epileptiform discharges (IEDs) and distant cortical regions subserve potential effects on cognition of patients with focal epilepsy. We hypothesize that "healthy" brain areas at a distance from the epileptic focus may respond to the interference of IEDs by generating inhibitory alpha and beta oscillations. We predict that m ...

Association Between Pain Catastrophizing and Pain and Cardiovascular Changes During a Cold-Pressor Test in Athletes

Author(s): Lentini M; Scalia J; Lebel FB; Touma F; Jhajj A; Darlington PJ; Dover G;

Context: Athletes are often exposed to pain due to injury and competition. Using preliminary evidence, researchers have shown that cardiovascular measures could be an objective measure of pain, but the cardiovascular response can be influenced by psychological factors, such as catastrophizing. Objective: To use a painful cold-pressor test (CPT) to measur ...

Data-driven methods distort optimal cutoffs and accuracy estimates of depression screening tools: a simulation study using individual participant data

Author(s): Bhandari PM; Levis B; Neupane D; Patten SB; Shrier I; Thombs BD; Benedetti A;

Objective: To evaluate, across multiple sample sizes, the degree that data-driven methods result in (1) optimal cutoffs different from population optimal cutoff and (2) bias in accuracy estimates. Study design and setting: A total of 1,000 samples of sample size 100, 200, 500 and 1,000 each were randomly drawn to simulate studies of different sample size ...

Weight bias and support of public health policies

Author(s): Edache IY; Kakinami L; Alberga AS;

Objectives: Public health policies have been proposed to help address prevalent Canadian obesity rates. Along with the increase in obesity prevalence, explicit weight bias is also rampant in Western society. This paper aimed to assess the association between explicit weight bias attitudes and Canadian public support of these policy recommendations. Metho ...

Putting ATM to BED: How Adipose Tissue Macrophages Are Affected by Bariatric Surgery, Exercise, and Dietary Fatty Acids

Author(s): Turner L; Santosa S;

With increasing adiposity in obesity, adipose tissue macrophages contribute to adipose tissue malfunction and increased circulating proinflammatory cytokines. The chronic low-grade inflammation that occurs in obesity ultimately gives rise to a state of metainflammation that increases the risk of metabolic disease. To date, only lifestyle and surgical inte ...

Identifying potential drug targets and candidate drugs for COVID-19: biological networks and structural modeling approaches

Author(s): Selvaraj G; Kaliamurthi S; Peslherbe GH; Wei DQ;

ackground: Coronavirus (CoV) is an emerging human pathogen causing severe acute respiratory syndrome (SARS) around the world. Earlier identification of biomarkers for SARS can facilitate detection and reduce the mortality rate of the disease. Thus, by integrated network analysis and structural modeling approach, we aimed to explore the potential drug targ ...
