In order to identify transporters and chelating agents that may be involved see more in transport and deposition of zinc in the barley grain, expression profiles have been generated of four different tissue types: the transfer cells, the aleurone layer, the endosperm, and the embryo. Cells from these tissues were isolated with the ‘laser capture microdissection’ technology and the extracted RNA was subjected to three rounds of T7-based amplification. The amplified RNA was subsequently hybridized to Affymetrix

22K Barley GeneChips. Due to the short average length of the amplified transcripts and the positioning of numerous probe sets at locations more than 400 base pairs (bp) from the poly(A)-tail, a normalization approach was used where the probe positions were taken into account. On the basis of the expression levels of a number of metal homeostasis genes, a working model is proposed for the translocation of zinc from the phloem to the storage sites in the developing grain.”
“Purpose Distress caused by cancer may have an important

impact on the quality of a couple’s relationship. This investigation examined perceived relationship changes in a sample of cancer patients and their partners, accounting for gender and role (i.e., patient or partner). Patients and Methods A total of 209 patients with different cancer types and stages and their Smoothened Agonist partners completed questionnaires with items on psychological distress (anxiety and depression), quality of life, and perceptions regarding phosphatase inhibitor positive and negative relationship changes. Results A total of 149 patients (71.3%)

and 156 partners (74.6%) reported that the diagnosis of cancer had changed their relationship. Of these, 121 (57.9%) patients and 116 (55.5%) partners reported positive changes only, whereas eight patients (3.8%) and 18partners (8.6%) indicated negative changes only. Twenty patients (9.6%) and 22 partners (10.5%) had experienced both positive and negative changes. In male patients and partners, negative dyadic changes were associated with lower quality of life and higher levels of anxiety and depression. This finding was similar in female partners, but not in female patients. The association between perceived negative relationship changes and both increased psychological distress and reduced quality of life remained significant even when controlled for gender and congruency of perception. Conclusions Although most couples in our sample reported growing closer while dealing with cancer, a small but sizeable percentage observed negative changes in their relationships, and these negative changes resulted in increased psychological distress and worse quality of life. Female partners were at greatest risk for these negative perceptions. Copyright (c) 2012 John Wiley & Sons, Ltd.
