multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...

Recent research has shown that the color red influences psychological functioning. Red is hypothesized to be linked to aggression and danger in evolution, and these links are enhanced by culture-specific uses of red. Thus, color meanings are thought to be grounded in biologically based proclivities and learned associations. However, to date, there has been no direct evidence for the influence o...

Erythrocytes are flexible cells specialized in the systemic transport of oxygen in vertebrates. This physiological function is connected to their outstanding ability to deform in passing through narrow capillaries. In recent years, there has been an influx of experimental evidence of enhanced cell-shape fluctuations related to metabolically driven activity of the erythroid membrane skeleton. Ho...

A new method to detect the identity of unexpected antibodies in the sera of prospective transfusion recipients is presented. The method is based on a macroscopic hemagglutination inhibition assay. In this assay, incubation of phenotypically defined test red blood cells with patient sera containing non-agglutinating antibodies to one or more specific antigen systems block monoclonal IgM inductio...

BACKGROUND Habitual red meat consumption was consistently related to a higher risk of type 2 diabetes in observational studies. Potentially underlying mechanisms are unclear. OBJECTIVE This study aimed to identify blood metabolites that possibly relate red meat consumption to the occurrence of type 2 diabetes. DESIGN Analyses were conducted in the prospective European Prospective Investigat...

A new preparation method has been successfully utilized for the fabrication of zinc oxide nanoparticles using auto-combustion technique and fuels (tartaric acid: TA, citric CA a mix between them) with molar ratio (Zn:TA; Zn:CA Zn:CA:CA = 1:1:0, 1:0:0.55 1:0.5:0.275). The as-fabricated powder (ZTA, ZCA ZCTA samples) annealed at 500 °C. was tested by different techniques like DRS, UV–Vis, FT-IR, ...

In our previous work, we have identified, in a model wine solution containing malvidin 3-glucoside, epicatechin and acetaldehyde, a new condensation product--hydroxylethyl-malvidin-3-glucoside-ethyl-epicatechin. The objective of this work was to verify the presence of such new condensation products in red wine. For this purpose, red wine was fractionated into various fractions by column chromat...

Direct drain of the cystic duct and drain of the biliary tract through an internal fistula into the duodenum in a 81-year-old man were endoscopically diagnosed without an operation.
