The 2008 financial crisis was a systemic problem with deep-rooted structural causes that created opportunities to engage in financial malfeasance, a form of corporate wrongdoing. However, few quantitative studies exist on the effects of organizational and political-legal arrangements on financial malfeasance. In this paper, we examine the effects of organizational and political-legal arrangements that emerged in the 1990s in the FIRE sector (i.e., financial, insurance, and real estate) on financial malfeasance...

Plants belonging to the genus Pennisetum have been reported to be resistant to atrazine, a widely used herbicide that also can cause serious pollution of soil and water. To evaluate the enzymatic antioxidant defense mechanism to the oxidative stress of atrazine, experiments focusing on the malondialdehyde (MDA) content and antioxidant enzyme in the leaf and root of Pennisetum americanum (L.) K. Schum (P. americanum) during long-term (68days) atrazine exposure were carried out. The test plant had not suffered obvious lipid membrane peroxidation, which was further confirmed by the result that the MDA content in the root and the leaf of the test plant did not significantly increase when treated with various concentrations of atrazine...

BACKGROUND: Calcium deposits in the aortic valve and mitral annulus have been associated with cardiovascular events and mortality. However, there is no accepted standard method for scoring such cardiac calcifications, and most existing methods are simplistic. The aim of this study was to test the hypothesis that a semiquantitative score, one that accounts for all visible calcium on echocardiography, could predict all-cause mortality and stroke in a graded fashion. METHODS: This was a retrospective study of 443 unselected subjects derived from a general echocardiography database...

Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD. Postoperatively, 46 patients (0.66 %) presented decline in consciousness with a positive finger-nose test (or failure to be tested) after wake up from the anesthesia, whom were focused on in this study...

Deprivation of mineral nutrients causes significant retardation of plant growth. This retardation is associated with nutrient specific and general stress-induced transcriptional responses. In this study we adjusted the external supply of iron, potassium and sulfur to cause the same retardation of shoot growth. Nevertheless, limitation by individual nutrients resulted in specific morphological adaptations and distinct shifts within the root metabolite fingerprint. The metabolic shifts affected key metabolites of primary metabolism and the stress-related phytohormones, jasmonic-, salicylic- and abscisic acid...

Internal pressure is often involved in neurodegeneration; intraocular and intraventricular pressure elevations over 20-30 cmH2O cause glaucoma and hydrocephalus, respectively. Here, we investigated enteric nerve degeneration in colon segments having tumor-induced stenosis and dilation and examined the mechanism of intraluminal pressure involvement. Histological examination revealed that the enteric ganglion neurons and neurites decreased in density in the dilated colons proportionate to the degree of dilation...

Phytoparasitic nematodes can infect a wide range of crop plants, and cause billions of dollars of agricultural losses each year. These parasites represent the largest source of biotic stress experienced by plants. The order Tylenchida comprises the most important parasitic nematodes, particularly the root-knot and cyst nematodes. These parasitic organisms obtain nutrients to support their development through complex interactions with their hosts. Plant-parasitic nematodes secrete a mixture of cell-wall degrading enzymes to facilitate migration through the plant root...

BACKGROUND: One root cause of the neglect of rabies is the lack of adequate diagnostic tests in the context of low income countries. A rapid, performance friendly and low cost method to detect rabies virus (RABV) in brain samples will contribute positively to surveillance and consequently to accurate data reporting, which is presently missing in the majority of rabies endemic countries. METHODOLOGY/PRINCIPAL FINDINGS: We evaluated a rapid immunodiagnostic test (RIDT) in comparison with the standard fluorescent antibody test (FAT) and confirmed the detection of the viral RNA by real time reverse transcription polymerase chain reaction (RT-qPCR)...

Cucumber (Cucumis sativus L.) is threatened by substantial yield losses due to the south root-knot nematode (Meloidogyne incognita). However, understanding of the molecular mechanisms underlying the process of nematode infection is still limited. In this study, we found that M. incognita infection affected the structure of cells in cucumber roots and treatment of the cytoskeleton inhibitor (cytochalasin D) reduced root-knot nematode (RKN) parasitism. It is known that Actin-Depolymerizing Factor (ADF) affects cell structure, as well as the organization of the cytoskeleton...

Nitrogen (N) is an essential macronutrient for plants. The increasingly severe environmental problems caused by N fertilizer application urge alleviation of N fertilizer dependence in crop production. In previous studies, we identified the Tibetan wild barley accessions with high tolerance to low nitrogen (LN). In this study, metabolic analysis was done on two wild genotypes (XZ149, tolerant and XZ56, sensitive) to understand the mechanism of LN tolerance, using a hydroponic experiment. Leaf and root samples were taken at seven time points within 18 d after LN treatment, respectively...

Peripheral nerve injury evokes a complex cascade of chemical reactions including generation of molecular radicals. Conversely, the reactions within nerve induced by stress are difficult to directly detect or measure to establish causality. Monitoring these reactions in vivo would enable deeper understanding of the nature of the injury and healing processes. Here, we utilized near-infrared fluorescence molecular probes delivered via intra-neural injection technique to enable live, in vivo imaging of tissue response associated with nerve injury and stress...
