The widespread use of β-lactam antibiotics has given rise to a dramatic increase in clinically-relevant β-lactamases. Understanding the structure/function relation in these variants is essential to better address the ever-growing incidence of antibiotic resistance. We previously reported the backbone resonance assignments of a chimeric protein constituted of segments of the class A β-lactamases TEM-1 and PSE-4 (Morin et al. in Biomol NMR Assign 4:127-130, 2010. doi: 10.1007/s12104-010-9227-8 ). That chimera, cTEM17m, held 17 amino acid substitutions relative to TEM-1 β-lactamase, resulting in a well-folded and fully functional protein with increased dynamics...

A procedure to regenerate cassava (Manihot esculenta Crantz) cultivars from Cameroon via somatic embryogenesis (SE) was developed. Shoot apical meristems and immature leaf lobes were used as explants on Murashige and Skoog (MS) basal medium containing 33 or 50 µM of the auxins Picloram (Pic), 2,4-Dichlorophenoxyacetic acid (2,4-D), Dicamba (Dic), and α-Naphthalene acetic acid. Cultivar performance was assessed using SE and number of somatic embryos produced. Overall, the frequency of primary somatic embryogenesis (PSE) and the mean number of somatic embryos produced varied considerably with genotype, type of auxin and concentration tested...

Since mushrooms have many bioactive components, they have been used as components in folk medicine. Because mycelium has an advantage when it comes to large-scale production, this study aimed to evaluate the antioxidant properties and anti-tyrosinase activity from 55 mycelia in culture media. Relatively high 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity was detected from the ethanol extract of culture media including mycelium (EECiM) of Morchella esculenta var. esculenta (MEVE), Auricularia polytricha (APO), Tremella aurantia (TAU), Volvariella bombycina (VBO), and Oudemansiella sp...

The brain combines information across sensory modalities to construct finely calibrated multisensory models of the body. The parameters of these models are largely dependent upon online sensory feedback, particularly visual. For example, visually magnifying a body part recalibrates somatosensory perception on it. Tool use has also been shown to recalibrate tactile perception on the tool-using limb. Here, we show that vision during tool use is both necessary and sufficient for recalibrating tactile perception...

Vection is an illusory perception of self-motion that can occur when visual motion fills the majority of the visual field. This study examines the effect of the duration of visual field movement (VFM) on the perceived strength of self-motion using an inertial nulling (IN) and a magnitude estimation technique based on the certainty that motion occurred (certainty estimation, CE). These techniques were then used to investigate the association between migraine diagnosis and the strength of perceived vection. Visual star-field stimuli consistent with either looming or receding motion were presented for 1, 4, 8 or 16s...

Chalcones and Mannich bases are a group of compounds known for their cytotoxicities. In this study restricted chalcone analogue, compound 2-(4-hydroxybenzylidene)-2,3-dihydroinden-1-one MT1, was used as a starting compound to synthesize new mono Mannich bases since Mannich bases may induce more cytotoxicity than chalcone analogue that they are derived from by producing additional alkylating center for cellular thiols. In this study, cyclic and acyclic amines were used to synthesize Mannich bases. All compounds were tested against Ca9-22 (gingival carcinoma), HSC-2, HSC-3 and HSC-4 (oral squamous cell carcinoma) as tumour cell lines and HGF (gingival fibroblasts), HPC (pulp cells) and HPLF (periodontal ligament fibroblasts) human normal oral cells as non tumour cell lines...

BACKGROUND: Elevated concentrations of LDL cholesterol are associated with the development of atherosclerosis and therefore are considered an important target for intervention to prevent cardiovascular diseases. The inhibition of cholesterol absorption in the small intestine is an attractive approach to lowering plasma cholesterol, one that is addressed by drug therapy as well as dietary supplementation with plant sterols and plant sterol esters (PSEs). OBJECTIVE: This study was conducted to test the hypothesis that the cholesterol-lowering effects of PSE require hydrolysis to free sterols (FSs)...

The hypothesis of this study was that peanut sprout extracts (PSE) could reduce fat accumulation through activating the transcription of SREBP-1c genes. Sprague-Dawley (SD) were randomly assigned into two groups and fed the following diet for 4 weeks; 10 normal fat (NF, 7 g of fat/100 g diet) and 30 high fat (HF, 20 g of fat/100 g diet). After 4 weeks, the HF group was divided into three groups; HF, HF with 15 mg of PSE/kg diet (HF+low PSE, 0.025% resveratrol), and HF with 30 mg of PSE/kg diet (HF+high PSE, 0...

There is no consensus guidelines for treating duodenal variceal bleeding, which is a rare and life-threatening complication of portal hypertension. Here we report an exceedingly unusual case in a 9-year-old boy who had developed left-sided portal hypertension after surgical treatment for pancreatoblastoma followed by a duodenal variceal bleeding with massive melena, severe anemia (hemoglobin 4.5 g/dL) and hypovolemic shock. Emergency partial splenic arterial embolization (PSE) provided a reduction of variceal bleeding and improved blood pressure...

The impact of depression interventions is often attenuated in women who have experienced trauma. We explored whether psychological avoidance could explain this phenomenon. We synthesized two pilot randomized trials of problem-solving education (PSE) among a total of 93 urban mothers. Outcomes included depressive symptoms and perceived stress. Mothers with avoidant coping styles experienced an average 1.25 episodes of moderately severe depressive symptoms over 3 months of follow-up, compared to 0.40 episodes among those with non-avoidant coping (adjusted incident rate ratio [aIRR] 2...

OBJECTIVE: Pegylated-interferon/ribavirin (peg-IFN/RBV) therapy with a protease inhibitor is the standard therapy for genotype 1b chronic hepatitis C. Despite improving treatment outcomes, patients with thrombocytopenia are often difficult to treat because interferon commonly exacerbates thrombocytopenia. In this study, partial splenic embolization (PSE) was performed in patients with hypersplenism-induced thrombocytopenia to determine the effectiveness of this method as a potential treatment...

β-Lactamases and extended-spectrum β-lactamases (ESBLs) producing pathogenic bacteria were widely studied previously in China, but were seldom focused on foodborne Salmonella. In this study, an investigation concerning β-lactamases and ESBLs producing Salmonella recovered from retail raw chickens was performed. Sixty of 699 foodborne Salmonella isolates were detected as β-lactamases and ESBLs-producing ones that covered 12 Salmonella serotypes and exhibited different pulsed-field gel electrophoresis genotypes...
