BACKGROUND Previous studies have found that social activities are beneficial for the reduction of cognitive decline (CD) in the elderly. However, knowledge regarding the types of social activities that reduce CD in later life is limited. The aim of this study is to examine which type of social activities reduce CD 4 years later among young-old (Y-O) and old-old (O-O) adults. METHODS We conduc...

Core decompression (CD) of the femoral head is one of the effective treatments of avascular necrosis (AVN), especially in the early stages of the disease. To investigate further the value of CD in treating the AVN, this study was performed on patients with symptomatic AVN with different etiologies who were treated with CD. This study was carried out on 25 patients (with the total number of 37 f...

Toxic heavy metal pollution of water and soil is a major environmental problem, and most conventional remediation approaches do not provide acceptable solutions. Wetland plants are being used successfully for the phytoremediation of trace elements in natural and constructed wetlands. This study demonstrates the phytoremediation potential of water hyacinth Eichhornia crassipes, for the removal o...

The objective of the present study was to compare the chemical and sensory properties of regular cream cheese (control) and cholesterol-reduced cream cheese manufactured using crosslinked β-cyclodextrin (β-CD) or powdered β-CD. Crosslinked β-CD was made using adipic acid. The composition of cream cheese treated by the crosslinked β-CD was similar to the regular cream cheese. Approximately 91% o...

OBJECTIVE To investigate the relationship between cognitive delay (CD) and behavior problems between ages 9 months and 5 years, while adjusting for covariates related to CD. METHODS Data were from 4 waves of the Early Childhood Longitudinal Study, Birth Cohort (n = 8000). Children were classified as typically developing (TD) or as having resolved, newly developed, or persistent CD between 9 a...

The complex formation between Cd(II) ions and N-acetylcysteine (H(2)NAC) in aqueous solution was investigated using Cd K- and L(3)-edge X-ray absorption and (113)Cd NMR spectroscopic techniques. Two series of 0.1 M Cd(II) solutions with the total N-acetylcysteine concentration c(H2NAC) varied between 0.2-2 M were studied at pH 7.5 and 11.0, respectively. At pH = 11 a novel mononuclear [Cd(NAC)(...

Background: Various industries produce and discharge wastes containing different heavy metals into the environment. Apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. Method: The cadmium (Cd) (II) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of Aspergillus versicolor were examined a...

Reported here is an organic-cation templated 4-connected anionic boron imidazolate framework [N(CH(3))(4)][Cd(SH)(2)B(im)(4)] (ABIF-1, im = imidazolyl), which is synthesized from the reaction of the supertetrahedral Cd(10)S(4)(SPh)(12) cluster with [N(CH(3))(4)]Cl and NaB(im)(4). The work represents an important step in the expansion of boron imidazolate frameworks from neutral BIFs to anionic ...

Cathepsin D (CD) up-regulation has been associated with human malignancy and poor prognosis. Thrombin up-regulated CD mRNA and protein in eight tumor cell lines as well as in human umbilical vascular endothelial cells (HUVEC). Thrombin increased the secretion of CD by 3- to 8-fold and enhanced chemotaxis ( approximately 2-fold) in 4T1 murine mammary CA cells, which was completely inhibited with...

CD studies of the deoxyoligomer series d(pT)(n) and d(pA)(n) show increasing CD maxima for oligo (dT)'s with chain length variation from two to seven, while oligo (dA)'s exhibit a decreasing CD maximum. Concentrated solutions of NaClO(4) cause a decrease in the CD of longer oligo (dT)'s towards the CD of d(pT)(2) which is different from oligo dA's. Probably base-sugar interactions are important...
