BACKGROUND: Early parenting practices, like infant feeding, can impact children's physical health. Additionally, negative prenatal maternal affect can influence feeding choices, like breastfeeding, and can have a detrimental effect on children's health. However, little is known about the contribution of positive maternal affect during pregnancy on feeding practices and children's health. METHOD: This study explored whether positive prenatal feelings influenced children's health during the first 18 months, and whether early feeding practices mediated the relationship between these two variables...

Bone mineral density (BMD) has been suggested to be associated with atherosclerosis. In the present study, we evaluated the association between lumbar BMD and the segments of carotid intima-media thickness (CIMT), a surrogate marker of subclinical atherosclerosis, in Korean adults, with consideration of sex and menopause status. Among 1,679 Korean adults who enrolled in a Healthy Twin Study, 723 men, 690 premenopausal women, and 266 postmenopausal women measured the CIMT at the common carotid artery intima-media thickness (CCA-IMT), carotid bifurcation intima-media thickness (BIF-IMT), internal carotid artery intima-media thickness (ICA-IMT) using B-mode ultrasound and lumbar BMD using dual-energy X-ray absorptiometry...

A chalcone-based Schiff base (5), capable of detecting iron (III) in partially aqueous media, has been designed, then synthesized by the condensation of 3-formyl-2-hydroxyquinoline and acetophenone. To determine iron (III) ion, a simple spectrofluorimetric method was developed by using the synthesized Schiff base. The developed method was validated by analyzing the certified reference material (CRM-SA-C Sandy Soil C). During the process of the determination of iron in food samples, satisfactory accuracy was obtained for spinach and rocket...

Acute lung injury/Acute Respiratory distress syndrome (ALI/ARDS) is an important cause of mortality in critically ill patients. Macrophages play an important role in the pathogenesis of ALI/ARDS. To investigate the role and underlying mechanisms of circulating monocytes and resident alveolar macrophages (AMs) in ALI/ARDS, we depleted circulating monocytes and AMs by clodronate-loaded liposome (CL) in lipopolysaccharide (LPS)-induced ALI/ARDS mouse model. Our results indicated that depletion of circulating monocytes by intravenous (i...

#7
Junbo Duan, Hui Zhong, Bowen Jing, Siyuan Zhang, Mingxi Wan
The axial resolution of ultrasonic imaging is confined by the temporal width of acoustic pulse generated by the transducer, which has a limited bandwidth. Deconvolution can eliminate this effect and, therefore, improve the resolution. However, most ultrasonic imaging methods perform deconvolution scan line by scan line, and therefore the information embedded within the neighbor scan lines is unexplored, especially for those materials with layered structures such as blood vessels. In this paper, a joint sparse representation model is proposed to increase the axial resolution of ultrasonic imaging...

Alec Hughes, Kullervo Hynynen
Phased arrays have a wide range of applications in focused ultrasound therapy. By using an array of individually driven transducer elements, it is possible to steer a focus through space electronically and compensate for acoustically heterogeneous media with phase delays. In this paper, the concept of focusing an ultrasound-phased array is expanded to include a method to control the orientation of the focus using a Tikhonov regularization scheme. It is then shown that the Tikhonov regularization parameter used to solve the ill-posed focus rotation problem plays an important role in the balance between quality focusing and array efficiency...

Product isolation from aqueous-organic reaction mixtures that contain high concentrations of whole cells constitutes a challenging task in bioprocessing. Stirring of the biphasic reaction media leads to the formation of solvent droplets coated by surface active components and an emulsion forms. We used an early focus on phase separation to simplify a whole-cell bioreduction. Octanol, heptanol, hexanol, hexane and dipropylether were tested as co-solvents in the E. coli catalyzed reduction of o-chloroacetophenone...

We report the case of a patient with multiple empyema present throughout his body, including chronic sinusitis and chronic suppurative otitis media, as well as subsequent epidural empyema, all caused by Streptococcus intermedius. A 38-year-old man presented with chief complaints of headache, left ear discharge, and nasal congestion. Imaging studies revealed pansinusitis, soft tissue signs in the mastoid cells, and otitis media. The patient was treated with meropenem hydrate, 6g/day. While clinical findings indicated improvement of the sinusitis, his headache did not improve...

BACKGROUND: Liraglutide, a GLP-1 analogue, exerts several beneficial non-glycemic effects in patients with type-2 diabetes (T2DM), such as those on body weight, blood pressure, plasma lipids and inflammation markers. However, the effects of liraglutide on cardiovascular (CV) risk markers in subjects with the metabolic syndrome (MetS) are still largely unknown. We herein explored its effects on various cardio-metabolic risk markers of the MetS in subjects with T2DM. METHODS: We performed an 18-month prospective, real-world study...

Biosurfactants are important in many areas; however, costs impede large-scale production. This work aimed to develop a global sustainable strategy for the production of biosurfactants by a novel strain of Bacillus amyloliquefaciens. Initially, Bacillus sp. strain 0G was renamed B. amyloliquefaciens subsp. plantarum (syn. Bacillus velezensis) after analysis of the gyrA and gyrB DNA sequences. Growth in modified Landy's medium produced 3 main recoverable metabolites: surfactin, fengycin, and acetoin, which promote plant growth...

Groundwater fluctuation is often overlooked and lack of study in the field contaminant hydrogeology. Hydraulic force from fluctuating groundwater tables leads to dissolution and subsequent enhanced advective transport of petroleum (e.g. BTEX) in contaminated subsurface system. A laboratory investigation of effect of the groundwater table fluctuation (GTF) on BTEX transport, taking toluene as a typical compound, in a typical representative model of aquifers subjected to a daily water-table fluctuation was undertaken in this work...

Present study reports a non-acetone producing Clostridium sporogenes strain as a potential producer of liquid biofuels. Alcohol production was positively regulated by sorbitol and instant dry yeast as carbon and nitrogen sources respectively. Media optimization resulted in maximum butanol and ethanol titer (gL(-1)) of 12.1 and 7.9 respectively. Depending on the combination of carbon sources, the organism was found to manipulate its metabolism towards synthesis of either ethanol or butanol, thereby affecting the total alcohol titer...

In an organized assembly in Arabidopsis thaliana plant, proton loss from the radical cation of zeaxanthin (Zea(+)) was found to occur under intense illumination, a possible component in photoprotection. A stable neutral radical is formed because of the favorable proton loss at C4(4') position(s) of the terminal ends of Zea(+) that extends the unpaired spin density distribution (notation Zea(4) or Zea(4') by symmetry). Proton loss from the radical cation of β-carotene (β-car(+)) to available proton acceptors was also detected in a PSII sample upon irradiation...

Distributions of a total of 21 elements were monitored in significantly lead-zinc polluted area using moss species (Hypnum cupressiforme and Camptothecium lutescens) used interchangeably, covering a denser sampling network. Interspecies comparison was conducted using Box-Cox transformed values, due to their skewed distribution. The median concentrations of trace elements in the both mosses examined decreased in the following order: Fe>Mn>Zn>Pb>Cu>Ni∼Cr∼As>Co>Cd>Hg. For almost all analyzed elements, H...

PURPOSE: Transplantation of in vitro cultured limbal epithelial stem cells (LESCs) is a treatment widely used for LESC deficiency. However, the number of limbal tissue donors is limited, and protocols for LESC cultivation often include compounds and/or feeder layers that can induce side effects and/or increase the cost of the culture procedure. We investigated the feasibility of obtaining more than one limbal primary culture (LPC) from the same biopsy using a culture medium in which several potentially harmful compounds were replaced at the same time by biosafe supplements, allowing the LESC cultivation without feeder layers...

A reactive phosphorescent probe for aza-heterocyclic drugs and toxins was developed, affording a supramolecular emission-switch-on chemosensor in water. Complex formation of the heterocycles with a platinum(II) precursor proceeds readily at ambient conditions, allowing for facile analyte screening. 52 structurally diverse compounds were tested, out of which 23 pyridines, imidazole, and triazoles formed strongly emissive complex aggregates. Importantly, they all can be clearly distinguished from each other through a principal component analysis, but often already by simple visual inspection, e...

Ethylene (C2H4) is a gaseous phytohormone that is involved in numerous aspects of plant development, playing a dominant role in senescence and fruit ripening. Exogenous ethylene applied during early plant development triggers the triple response phenotype; a shorter and thicker hypocotyl with an exaggerated apical hook. Despite the intimate relationship between plants and bacteria, the effect of exogenous ethylene on bacteria has been greatly overlooked. This is partly due to the difficulty of controlling gaseous ethylene within the laboratory without specialized equipment...
