Predictors of successful weight loss in children treated at a community hospital-based tertiary care pediatric weight management program.

Childhood obesity is a major public health concern. However, predictors of successful outcomes for patients treated at multidisciplinary community hospital-based pediatric weight management programs remain poorly understood. We conducted a retrospective analysis to evaluate 633 pediatric patients from ages 2 to 18 at a tertiary pediatric weight management program in 2018.

Child-feeding practices among Chinese-American and non-Hispanic white caregivers.

This study compared child-feeding and related practices with child weight status between Chinese-American and non-Hispanic white caregivers who attended three community health centers. Study participants were caregivers of 50 Chinese-American and 108 non-Hispanic white children aged 2-12 years who completed a short version of the child feeding questionnaire in English or Chinese. The feeding behaviors assessed were concern, pressure, restriction, and monitoring.

Ligand binding and inhibition of an oxygen-sensitive soluble guanylate cyclase, Gyc-88E, from Drosophila.

Soluble guanylate cyclase (sGC) uses a ferrous heme cofactor as a receptor for NO and once bound activates the enzyme for the conversion of GTP to cGMP. The heme cofactor in sGC does not bind oxygen, thereby allowing it to selectively bind NO despite a cellular concentration of oxygen (microM) that is much higher than signaling concentrations of nitric oxide (nM). The molecular details of this ligand discrimination against oxygen have emerged and allowed for predictions regarding ligand specificity in the sGC family.

Nitric oxide binding to prokaryotic homologs of the soluble guanylate cyclase beta1 H-NOX domain.

The heme cofactor in soluble guanylate cyclase (sGC) is a selective receptor for NO, an important signaling molecule in eukaryotes. The sGC heme domain has been localized to the N-terminal 194 amino acids of the beta1 subunit of sGC and is a member of a family of conserved hemoproteins, called the H-NOX family (Heme-Nitric Oxide and/or OXygen-binding domain). Three new members of this family have now been cloned and characterized, two proteins from Legionella pneumophila (L1 H-NOX and L2 H-NOX) and one from Nostoc punctiforme (Np H-NOX).

Vitamin E status in children with cystic fibrosis and pancreatic insufficiency.

Vitamin E status was compared in 69 children (7.0-10.0 years) with cystic fibrosis and pancreatic with the National Health and Nutrition Examination Survey III sample (6.

A molecular basis for NO selectivity in soluble guanylate cyclase.

Soluble guanylate cyclases (sGCs) function as heme sensors that selectively bind nitric oxide (NO), triggering reactions essential to animal physiology. Recent discoveries place sGCs in the H-NOX family (heme nitric oxide/oxygen-binding domain), which includes bacterial proteins from aerobic and anaerobic organisms. Some H-NOX proteins tightly bind oxygen (O2), whereas others show no measurable affinity for O2, providing the basis for selective NO signaling in aerobic cells.
