The study was carried out to enumerate fungal contamination, and toxigenicity of Aspergillus flavus strains on cacao beans during drying storage. As many as 3500 g storage were purchased from smallholder farmers the plantation areas at Karo Regency, Northern Sumatera. percentage contaminated by fungi conducted using direct plating. Fungal populations soil determined dilution followed pour plate...

The P. angelicae group from China was studied, and six new species are described: P. hanmiensis, n. sp., P. nanlingensis, n. sp., P. reduncicauda, n. sp., P. spargocerca, n. sp., P. subincana, n. sp., and P. varimargina, n. sp. A key to the identification of males of the 40 Chinese species is given.

abstract cation exchange capacity (cec) is an important characteristic of soil in terms of nutrient and water holding capacities and contamination management. measurement of cec is laborious and time-consuming. therefore, cec estimation through other easily - measured properties is desirable. in this study, ptfs for estimation of cation exchange capacity from basic soil properties such as parti...

The aim of this study was to identify cancer stem cells (CSC) from three hepatocellular carcinoma (HCC) cell lines and to screen for specific microRNAs (miRNAs) regulating CSCs. Side population (SP) phenotype analysis was used. Four factors in the staining process, the incubation time, shaking interval, culture time and Hoechst 33342 concentration were explored, respectively, to define the SP s...

abstract- the information on the spatial properties of soil is vital to improve soil management and to increase the crop productivity. geostatistical analysis technique is one of the most important methods for determining the spatial properties of soil. the aim of this study was to investigate spatial variability of soil chemical and physical attributes for field management in eastern shiraz, i...

The bacteriophage T4 spackle gene, which maintains host membrane integrity, mapped at the same position as gene 40 (head morphogenesis). The cloned spackle gene complemented and cross-reactivated a gene 40 mutant. Like the spackle mutant, gene 40 mutants were defective in genetic exclusion. Apparently, genes spackle and 40 are the same gene.

Background: establishing a regular respiratory condition in the infants is one of the basic considerations in NICU.  Newborns show noticeable breath alterations in response to even low concentrations of some fragrance. Aim: determining the effect of breast milk odor on oxygen saturation and respiratory rate in premature infants. Methods: In this four-group randomized clinical trial, 180 prematu...

Magnesium borate hydroxide (MBH) nanowhiskers were synthesized using a one step hydrothermal process with different surfactants. The effect surfactants have on the structure and morphology of the MBH nanowhiskers has been investigated. The X-ray diffraction profile confirms that the as-synthesized material is of single phase, monoclinic MgBO(2)(OH). The variations in the size and shape of the d...

Methods suggested for the determination of carbon monoxide in blood may be considered as belonging to either of these two classes: first, those in which the relative content of carbon monoxide in blood is measured; second, those in which the absolute quantity of carbon monoxide per given quantity of blood is determined. In the first class, the result is expressed as the percentage saturation of...
