#1
Hyun-Suk Park, Sang Hyon Oh
Since the industrialization of swine production in the late 1900s, swine farms in the United States, as well as in Europe, have largely become consolidated. Pig farms became larger in size but fewer in number, with 91% of market pigs being produced by large operations with 5,000 or more pigs on-site in the US, and only 3% of the total utilized agricultural land representing organic farming. Such change in the market made it difficult for small farmers to stay competitive, forcing them to find alternative ways to reduce the cost of production and increase profit using the outdoor production system...

Methane (CH4) is one of the most potent greenhouse gases. Although forest and grassland soils generally consume atmospheric CH4, the quantities and spatiotemporal changes in CH4 uptake remain largely uncertain for these ecosystems at the global scale. In this study, we developed an empirical model to estimate the CH4 uptake in global forest and grassland soils during the period 1981-2010. We estimated that the mean values of CH4 uptake were 9.16 (± 3.84) Tg yr(-1) in forest soils and 3.73 (± 1.41) Tg yr(-1) in grassland soils during the study period...

BACKGROUND: China's soil pollution poses serious health risks. However, data regarding the soil ingestion rate (SIR) of the Chinese population, which is critical to assessing associated health risks, are lacking. OBJECTIVES: We estimated soil ingestion of 177 Chinese children from Guangdong, Hubei, and Gansu Provinces. METHODS: We conducted this investigation by employing a tracer mass-balance method. We collected a duplicate of all food consumed and all feces and urine excreted on 1 d () and over 3 consecutive d (), as well as soil samples from play areas and drinking-water samples...

Glaucoma is one of the leading causes of permanent vision loss. It is an ocular disorder caused by increased fluid pressure within the eye. The clinical methods available for the diagnosis of glaucoma require skilled supervision. They are manual, time consuming, and out of reach of common people. Hence, there is a need for an automated glaucoma diagnosis system for mass screening. In this paper, we present a novel method for an automated diagnosis of glaucoma using digital fundus images. Variational mode decomposition (VMD) method is used in an iterative manner for image decomposition...

Duncan Taylor, Ash Harrison, David Powers
Electropherograms are produced in great numbers in forensic DNA laboratories as part of everyday criminal casework. Before the results of these electropherograms can be used they must be scrutinised by analysts to determine what the identified data tells them about the underlying DNA sequences and what is purely an artefact of the DNA profiling process. This process of interpreting the electropherograms can be time consuming and is prone to subjective differences between analysts. Recently it was demonstrated that artificial neural networks could be used to classify information within an electropherogram as allelic (i...

House mice (Mus musculus) emit complex ultrasonic vocalizations (USVs) during social and sexual interactions, which have features similar to bird song (i.e., they are composed of several different types of syllables, uttered in succession over time to form a pattern of sequences). Manually processing complex vocalization data is time-consuming and potentially subjective, and therefore, we developed an algorithm that automatically detects mouse ultrasonic vocalizations (Automatic Mouse Ultrasound Detector or A-MUD)...

Previous studies indicate that lying consumes cognitive resources, especially working memory (WM) resources. Considering the dual functions that WM might play in lying: holding the truth-related information and turning the truth into lies, the present study examined the relationship between the information storage and processing in the lie construction. To achieve that goal, a deception task based on the old/new recognition paradigm was designed, which could manipulate two levels of WM load (low-load task using 4 items and high-load task using 6 items) during the deception process...

Fetal alcohol spectrum disorder (FASD), the result of fetal alcohol exposure (FAE), affects 2-11% of children worldwide, with no effective treatments. Hippocampus-based learning and memory deficits are key symptoms of FASD. Our previous studies show hypothyroxinemia and hyperglycemia of the alcohol-consuming pregnant rat, which likely affects fetal neurodevelopment. We administered vehicle, thyroxine (T4) or metformin to neonatal rats post FAE and rats were tested in the hippocampus-dependent contextual fear-conditioning paradigm in adulthood...

We propose a novel relighting approach that takes advantage of multiple color plus depth images acquired from a consumer camera. Assuming distant illumination and Lambertian reflectance, we model the reflected light field in terms of spherical harmonic coefficients of the Bi-directional Reflectance Distribution Function (BRDF) and lighting. We make use of the noisy depth information together with color images taken under different illumination conditions to refine surface normals inferred from depth. We first perform refinement on the surface normals using the first order spherical harmonics...

Physical condition and an optimized diet are relevant to enhance performance and recovery. The diet composition and meal frequency of eleven elite wheelchair basketball players were estimated using a 3-day food-weighing diary in two months during the precompetitive-period. Performance was determined through a 20 m sprint test. The players consumed 4.2 ± 0.8 meals/day in May and 4.5 ± 0.9 meals/day in June, resulting in total energy intakes of 2492 ± 362 kcal/d and 2470 ± 497 kcal/d, respectively. The macronutrient distribution was 3...

It is estimated that 30% of people older than 60 years suffer from hyposalivation or dry mouth. Drinking water frequently has been recommended as a safe, non-pharmacologic way to combat hyposalivation. The saliva in patients with dry mouth is acidic. Beverages consumed daily may have an erosive potential on teeth. The pH and the mineral content of the beverage determine its erosive potential. An acidic beverage, therefore, may have harmful effects on mineralized tooth structures, causing erosion of enamel, dentin, and cementum...

Although many approaches to the restoration of edentulous maxillae and mandibles have been developed, these treatments can be costly and time-consuming, and involve extensive grafting of the edentulous ridges. The All-on-4® treatment concept has been shown to be a viable alternative, with limited grafting required, using at least four regular-platform implants to support an acrylic, screw-retained provisional prosthesis before the fabrication of a definitive prosthesis. This case presentation will discuss the use of narrow-platform (3...

In this work, an elegantly designed host-guest recognition-assisted electrochemical release was established and applied in a reusable electrochemical biosensor for the detection of microRNA-182-5p (miRNA-182-5p), a prostate cancer biomarker in prostate cancer, based on the DNA cross configuration-fueled target cycling and strand displacement reaction (SDR) amplification. With such design, the single target miRNA input could be converted to large numbers of single-stranded DNA (S1-Trp and S2-Trp) output which could be trapped by cucurbit[8]uril-methyl viologen (CB-8-MV2+) based on the host-guest recognition, significantly enhancing the sensitivity for miRNA detection...

Currently, diagnosis of colon cancer is based on manual examination of histopathological images by a pathologist. This can be time consuming and interpretation of the images is subject to inter- and intra-observer variability. This may be improved by introducing a computer-aided diagnosis (CAD) system for automatic detection of cancer tissue within whole slide hematoxylin and eosin (H&E) stains. Cancer disrupts the normal control mechanisms of cell proliferation and differentiation, affecting the structure and appearance of the cells...

Chronic cutaneous wound infections and surgical site infections (SSIs) present a huge burden on the healthcare system and can lead to increased morbidity and mortality. Current diagnostic methods of identifying and confirming infection involve culture-based and molecular methods. Both techniques are time consuming and delays commonly lead to un-targeted empirical treatment. An ideal diagnostic method would be non-invasive and highly sensitive and detect pathogenic organisms with a high degree of accuracy in order to allow targeted treatment...

1 I. 1 II. 2 III. 5 IV. 10 12 References 12 SUMMARY: Photosynthesis is one of the most important biological processes on Earth. It provides the consumable energy upon which almost all organisms are dependent, and modulates the composition of the planet's atmosphere. To carry out photosynthesis, plants require a large cohort of genes. These genes encode proteins that capture light energy, store energy in sugars and build the subcellular structures required to facilitate this energy capture. Although the function of many of these genes is known, little is understood about the transcriptional networks that coordinate their expression...

The main objective of this work was to investigate the effects of feeding Lys-deficient diets on muscle biochemical characteristics, particularly intramuscular fat concentration and fatty acid profile, in a fatty (Iberian) and a conventional pig genotype (Landrace × Large White [LDW]) maintained in identical experimental conditions. Performance and plasma metabolite changes were also monitored. Twenty-eight barrows of 10 kg initial BW, 14 of Iberian and 14 of LDW breed, were randomly assigned to each of 2 experimental diets in a 2 × 2 factorial arrangement (2 breeds × 2 diets)...

Current methods used for oral administration of pathogens to piglets are stressful for the animals because of fixation and use of inoculation methods such as oral gavage. In the present study an alternative way to challenge piglets with Typhimurium (ST) is investigated. The strategy was to incorporate the in a feed matrix, which is fed to the piglets and eaten voluntary. Different types of feed matrices were tested for their absorption capacity, handling properties, and palatability to piglets. Furthermore, the viability of ST in feed matrices was studied...

This study was conducted to determine whether circulating concentrations of blood isoprostanes can be used as an effective biomarker in lambs to predict degradation of color and/or lipid stability in meat. Lambs ( = 84) were fed diets of either lucerne pasture, annual ryegrass pasture, a commercial feedlot pellet, or a combination of annual ryegrass and feedlot pellet for 8 wk, including a 2-wk adaptation period. Blood isoprostane concentration at wk 0, 4, 6 or 8 of feeding was determined. Blood isoprostane concentration for each animal was then correlated with muscle biochemical components that impact color and/or lipid oxidative status during retail display...
