oxalic acid/atrophy

Sclerotinia sclerotiorum, a pathogen of more than 600 host plants, secretes oxalic acid to regulate the ambient acidity and provide conducive environment for pathogenicity and reproduction. Few Aspergillus spp. were previously proposed as potential biocontrol agents for S. sclerotiorum as they

Microorganisms generally degrade wood when moisture, oxygen and other environmental factors provide favorable growing conditions. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to study the development and transformation of the products formed during

Reported similarities in the acute toxic effects of 1,2-dibromo-3-chloropropane (DBCP), 3-chloro-1,2-propaneoxide (epichlorohydrin, ECH), 3-chloro-1,2-propanediol (alphachlorohydrin, ACH), and oxalic acid (OA) have been suggested as presumptive evidence that the metabolism of DBCP to OA, via ECH and

Immunohistochemisty with RD3, a monoclonal antibody specific for three-repeat (3R) tau, is sometimes hampered by diffuse neuronal staining on formalin-fixed, paraffin-embedded sections pretreated with formic acid and heating. Additional pretreatment with potassium permanganate followed by oxalic

Ethylene glycol can cause both renal and developmental toxicity, with metabolism playing a key role in the mode of action (MOA) for each form of toxicity. Renal toxicity is ascribed to the terminal metabolite oxalic acid, which precipitates in the kidney in the form of calcium oxalate crystals and

Live sea cucumbers (Stichopus japonicus) were stored in a solution containing oxalic acid and tea polyphenols as natural metal ion chelators. The inhibitory effects of these chelators on the autolysis phenomenon and the underlying mechanism of action were investigated for the first time by using

Two mildly demented patients with emotional disorder presented massive cortical argyrophilic grains (ArG) in the limbic area and coiled bodies mainly in the white matter. Immunohistochemically, the ArG consisted of partially ubiquitinated full-length phosphorylated tau. A modified Gallyas-Braak

Semiacute toxicity of cola fluid, Coca-Cola, conducting for approximately a month in rats, was studied. A trend of cariogenicity of Coca-Cola was strongly indicated. When the fluid was given ad libitum, decarbonized Coca-Cola and carbohydrate solution, consisted 8% of glucose and 3.5% of sugar and

The prevalence of nontuberculous mycobacteria (NTM) recovered from patients with cystic fibrosis (CF) appears to be increasing, probably related to improved surveillance and microbiological procedures and an increase in the life expectancy of patients with CF. The distinction between active lung

The effect of the actions of some lichens on the quality of ceramic roofing tiles was investigated in view of textural and microstructural changes considering their biocorrosion resistance. Two types (extruded and pressed) of the real ceramic roofing tiles aged 6 to 10 years, as well as the ceramic

The oxidizing enzyme laccase produced by many fungi is generally considered to be active in the biodegradation of lignin, a major plant cell wall component highly resistant to microbial attack. The enzyme is secreted at high levels by the P-type of the highly aggressive pathogen Heterobasidion

Double immunofluorolabeling for 3-repeat (3R) and 4-repeat (4R) tau was performed with two monoclonal antibodies, RD3 and RD4, after an additional pretreatment with potassium permanganate and oxalic acid to eliminate nonspecific 3R tau cytoplasmic staining. This method involves hyperdilution of one

Fluoride phosphors as red components for warm WLEDs have attracted a tremendous amount of research attention. But these phosphors are extremely sensitive to moisture, which seriously limits its practical industrial applications. To tackle with this problem, unlike all the straight-forward preventive

Soil and rock surfaces support microbial communities involved in mineral weathering processes. Using selective isolation, fungi were obtained from limestone surfaces of Mayan monuments in the semi-arid climate at Yucatan, Mexico. A total of 101 isolates representing 53 different taxa were studied.

Ten of 100 mature ewes were afflicted with acute oxalate toxicosis within 40 hours after being temporarily penned in a lot that contained considerable growing Rumex crispus (curly dock). Clinical signs of toxicosis included excess salivation, tremors, ataxia, and recumbency. Affected ewes were
