Effect of a non-dieting lifestyle randomised control trial on psychological well-being and weight management in morbidly obese pre-menopausal women.

Objective This study examined the effects of a non-dieting lifestyle intervention approach for morbidly obese women designed in the framework of the self-determination theory (SDT) and Health at Every Size on weight maintenance and psychological functioning. Participants and design Predominantly white (97%), morbidly obese (BMI ≥ 35 kg m-2 with at least one co-morbid condition or a BMI ≥ 40 kg m-2) pre-menopausal women (N = 62), aged between 24 and 55 years were initially randomly assigned to 12 weeks of lifestyle intervention (IIG) or delayed start control group (DSCG). The program consisted of 3 months intensive lifestyle intervention followed by 9 month maintenance phase. The DSCG group commenced the program after 3 months. Results and conclusions Initially, the IIG showed a significant decrease in body weight (baseline to end of the RCT phase) compared with a significant increase in the DSCG group. However, no significant changes in weight status were evident in either group at 12 months compared with baseline. The 3-month intensive intervention resulted in significantly improved psychological functioning in both groups, which were maintained at 12 months. The study provides additional support for a non-dieting, theory-based, lifestyle approach to weight management and psychological well-being among morbidly obese females

Further studies on a hybrid cell-surface antigen associated with human chromosome 11 using a monoclonal antibody

A monoclonal antibody has been obtained that recognizes an antigen encoded by human chromosome 11. We present evidence that this monoclonal antibody recognizes the same or a similar antigenic activity as that previously called a 1 . Genetic information necessary for a 1 expression and recognition by the monoclonal antibody both map to 11p13 → 11pter. Mutants that have lost a 1 are no longer recognized by the monoclonal antibody. The macroglycolipid fraction of human erythrocyte membranes which contains the a 1 antigenic activity is able to convert antigen-negative Chinese hamster ovary cells into cells which are killed by the monoclonal antibody plus complement.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45556/1/11188_2005_Article_BF01543049.pd

Systematic, continental scale temporal monitoring of marine pelagic microbiota by the Australian Marine Microbial Biodiversity Initiative

Sustained observations of microbial dynamics are rare, especially in southern hemisphere waters. The Australian Marine Microbial Biodiversity Initiative (AMMBI) provides methodologically standardized, continental scale, temporal phylogenetic amplicon sequencing data describing Bacteria, Archaea and microbial Eukarya assemblages. Sequence data is linked to extensive physical, biological and chemical oceanographic contextual information. Samples are collected monthly to seasonally from multiple depths at seven sites: Darwin Harbour (Northern Territory), Yongala (Queensland), North Stradbroke Island (Queensland), Port Hacking (New South Wales), Maria Island (Tasmania), Kangaroo Island (South Australia), Rottnest Island (Western Australia). These sites span ~30° of latitude and ~38° longitude, range from tropical to cold temperate zones, and are influenced by both local and globally significant oceanographic and climatic features. All sequence datasets are provided in both raw and processed fashion. Currently 952 samples are publically available for bacteria and archaea which include 88,951,761 bacterial (72,435 unique) and 70,463,079 archaeal (24,205 unique) 16 S rRNA v1-3 gene sequences, and 388 samples are available for eukaryotes which include 39,801,050 (78,463 unique) 18 S rRNA v4 gene sequences
