A Qualitative Examination of Parent Engagement in a Family-Based Childhood Obesity Program.

Low parent engagement is frequently identified as a barrier to effective implementation of family-based childhood obesity prevention and control programs. A more nuanced understanding of factors affecting parent engagement is important for improving implementation and, ultimately, program efficacy. This qualitative study examined factors influencing parent engagement in a family-based childhood obesity prevention and control program.

Gonadogenesis and slow proliferation of germ cells in juveniles of cultured yellowfin tuna, Thunnus albacares.

To develop techniques for seedling production of yellowfin tuna, the behavior of primordial germ cells (PGCs) and gonadogenesis were examined at 1-30 days post hatching (dph) using morphometric analysis, histological examination, and in situ hybridization. Immediately after hatching, PGCs were located on the dorsal side of the posterior end of the rectum under the peritoneum of the larvae, and at 3 dph they came into contact with stromal cells. PGCs and stromal cells gradually moved forward from the anus prior to 5 dph.

A highly sensitive sandwich ELISA for the determination of glycomacropeptide to detect liquid whey in raw milk.

Milk processing industries and distributors have problems with adulteration of liquid milk by the addition of bovine cheese whey. Recently, the detection of fraudulent manipulation of milk with whey has focused on the identification of glycomacropeptide (GMP). Current non-immunological methods to detect GMP in dairy products are expensive and time-consuming or have low sensitivity.
