biosights: March 18, 2013 - Breaking egg symmetry

submitted by: JCB
During the first meiotic division of mammalian oocytes, the meiotic spindle and chromosomes move from the interior to the periphery of the cell. Yi et al. reveal that chromosome migration occurs in two sequential phases driven by the actin nucleators Fmn2 and the Arp2/3 complex. This biosights episode presents the paper by Yi et al. from the March 4, 2013, issue of The Journal of Cell Biology and includes an interview with senior author Rong Li (Stowers Institute for Medical Research, Kansas...

Beneficial effects of a higher-protein breakfast on the appetitive, hormonal, and neural signals controlling energy intake regulation in overweight/obese, “breakfast-skipping,” late-adolescent girls

submitted by: hurstn
Background: Breakfast skipping is a common dietary habit practiced among adolescents and is strongly associated with obesity. Objective: The objective was to examine whether a high-protein (HP) compared with a normal-protein (NP) breakfast leads to daily improvements in appetite, satiety, food motivation and reward, and evening snacking in overweight or obese breakfast-skipping girls. Design: A randomized crossover design was incorporated in which 20 girls [mean 6 SEM age: 19 6 1 y;...

MWV Episode 68 - Threading the NEIDL: TWiV Goes Inside a BSL-4

submitted by: MicrobeWorld
Constructed in 2009 in the highly populated South End neighborhood of Boston, Massachusetts, the National Emerging Infectious Diseases Laboratories (NEIDL) facility contains labs that operate at biosafety levels 2, 3 and 4. Due to its location the NEIDL has faced a raft of legal and regulatory hurdles that have prevented BSL-3 and BSL-4 labs from becoming functional. "Threading the NEIDL," is a 1-hour documentary narrated by Vincent Racaniello, PhD, Higgins Professor of Microbiology &...

Vitamin D supplementation and calcium absorption during caloric restriction: a randomized double blind trial

submitted by: shapses
Background: Weight loss (WL) is associated with a decrease in calcium absorption and may be one mechanism that induces bone loss with weight reduction. Objective: Because vitamin D supplementation has been shown to increase true fractional calcium absorption (TFCA), the goal of this study was to examine the effect of vitamin D during WL or weight maintenance (WM). Design: A randomized, placebo-controlled, double-blind 6-wk study was conducted in 82 postmenopausal women [BMI (in kg/...

Earlier introduction of ‘agüitas’ is associated with higher risk for stunting among infants and toddlers in the Western Highlands of Guatemala

submitted by: cmdoak
Background: In many cultures, simple herbal infusions, thin gruels or sweetened water (‘agüitas’ in Guatemalan parlance) are given to infants and toddlers. Formative research shows the use of agüitas in early child feeding to be deeply embedded in Guatemalan culture. Objective: To examine the prevalence and timing of introduction of agüitas during early life in a low-income population of metropolitan Quetzaltenango in relation to child stunting. Design: Responses from 456 mothers of...
