Associations between body dissatisfaction, importance of appearance, and aging anxiety with depression, and appearance-related behaviors in women in mid-life.

The impacts of body dissatisfaction have been widely studied among adolescent girls, but much less in women in mid-life. In this study, we evaluated the associations between body dissatisfaction, psychological health and behaviors used to manage age-related changes, in an online survey of 331 women aged 45-65. Body dissatisfaction, importance of appearance and aging anxiety were associated with higher depression scores.

Bovine and ovine blood mononuclear leukocytes differ markedly in innate immune responses induced by Class A and Class B CpG-oligodeoxynucleotide.

Cytosine-phosphate-guanosine (CpG)-DNA can induce an impressive array of innate immune responses that may directly or indirectly contribute to the clearance of infectious agents. Assays, such as lymphocyte proliferative responses, have been used to demonstrate that the immunostimulatory activity of CpG-DNA is conserved among a broad range of vertebrate species, but no studies have been completed to determine if qualitative differences exist among species for CpG-oligodeoxynucleotide (ODN)-induced innate immune responses. In this study, we assessed the capacity of a Class A (ODN 2216) and a Class B (ODN 2007) CpG-ODN to induce innate immune responses in two closely related species, ovine (n = 28) and bovine (n = 29).

Safety and efficacy of CpG-containing oligodeoxynucleotides as immunological adjuvants in rabbits.

The efficacy of oligodeoxynucleotides containing unmethylated CpG dinucleotides (CpG ODN) as an adjuvant for rabbits was assessed alone and in combination with aluminum hydroxide (CpG/alum). The CpG/alum combination elicited a greater immune response to several antigens compared to Freund's adjuvant. A non-CpG/alum combination did not have the same effects as CpG/alum suggesting that the adjuvanticity was related to the CpG motifs.

Safety of CpG oligodeoxynucleotides in veterinary species.

Bacterial DNA and synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG motifs in particular sequence contexts (CpG ODN) are recognized as a danger signal by the innate immune system of vertebrates. For this reason, CpG ODNs have a potential application as both an adjuvant and nonspecific immune modulator and are currently being evaluated in a number of human and veterinary clinical trials. Given their potent immunostimulatory activity, CpG ODNs could possibly induce adverse reactions.

Biological activity of immunostimulatory CpG DNA motifs in domestic animals.

Bacterial DNA contains a much higher frequency of CpG dinucleotides than are present in mammalian DNA. Furthermore, bacterial CpG dinucleotides are often not methylated. It is thought that these two features in combination with specific flanking bases constitute a CpG motif that is recognized as a "danger" signal by the innate immune system of mammals and therefore an immune response is induced when these motifs are encountered.
