Activity of ammonia-oxidizing bacteria (AOB) to simultaneous variation in Zn(2+) concentration (0.01-3.5mg/L), temperature (23-33°C), and AOB concentration (3-30 × 10(6)gene copies/mL) in a steel industry wastewater treatment plant was evaluated. Two equations were developed to describe the lag period (i.e., AOB acclimation) and ammonia oxidation rate(More)
Changes in algal and bacterial communities during thiocyanate (SCN(-)) decomposition in a microalga-mediated process were studied. Pyrosequencing indicated that Thiobacillus bacteria and Micractinium algae predominated during SCN(-) hydrolysis, even after its complete degradation. Principal components analysis and evenness profiles (based on the(More)
In mammals, the increased secretion of arginine-vasopressin (AVP) (antidiuretic hormone) and oxytocin (natriuretic hormone) is a key physiological response to hyperosmotic stress. In this study, we examined whether chronic hyperosmotic stress weakens GABA(A) receptor-mediated synaptic inhibition in rat hypothalamic magnocellular neurosecretory cells (MNCs)(More)
The number of vertebrae is defined strictly for a given species and depends on the number of somites, which are the earliest metameric structures that form in development. Somites are formed by sequential segmentation. The periodicity of somite segmentation is orchestrated by the synchronous oscillation of gene expression in the presomitic mesoderm (PSM),(More)
Hematogenous metastasis to skeletal muscle from urothelial carcinoma is extremely rare and metastatic disease to skeletal muscle tends to be found in people with advanced-stage neoplasm. We report in this paper a case of left sartorius muscle metastasis from urothelial cell carcinoma. A left nephroureterectomy with bladder cuff excision was performed and(More)
Histamine, a neurotransmitter/neuromodulator implicated in the control of arousal state, exerts a potent phase-shifting effect on the circadian clock in the rodent suprachiasmatic nucleus (SCN). In this study, the mechanisms by which histamine resets the circadian clock in the mouse SCN were investigated. As a first step, Ca(2+) -imaging techniques were(More)
Due to recent developments in nanotechnology, nanomaterials (NMs) such as graphene oxide (GO) may enter the soil environment with mostly unknown consequences. We investigated the effects of GO on soil microbial activity in a 59-day soil incubation study. For this, high-purity GO was prepared and characterized. Soils were treated with up to 1 mg GO g(-1)(More)
Rice straw is one of the most abundant renewable energy sources available. Through anaerobic acidogenesis, the substance of rice straw can be converted to volatile fatty acids (VFAs). VFAs itself is of value and is a precursor to biofuels. Hence, it can be converted to mixed alcohols by addition of hydrogen, and biodiesel can be produced as a carbon source(More)
Qualitative and quantitative molecular analysis techniques were used to determine associations between differences in methanogenic microbial communities and the efficiency of batch anaerobic digesters. Two bioreactors were initially seeded with anaerobic sludge originating from a local municipal wastewater treatment plant and then supplemented with swine(More)
Digital tomosynthesis (DTS) provides slice images of an object using conventional radiographic methods with high in-plane resolution. The objective of this study was to explore the potential of DTS for describing microstructural, stiffness and stress distribution properties of vertebral cancellous bone. Forty vertebrae (T6, T8, T11, and L3) from 10 cadavers(More)
