Ex Input:
The effects of a zinc supplement on maternal zinc status and milk zinc concentrations through > or = 7 mo of lactation were examined. Seventy-one lactating women received either a daily 15-mg zinc supplement (ZS, n = 40) or placebo (NZS, n = 31) started by 2 wk postpartum in a double-blind, randomized design. Overall mean zinc intakes were 13.0 +/- 3.4 mg/d for the NZS group and 25.7 +/- 3.9 mg/d (including supplement) for the ZS group. Plasma zinc concentrations of the ZS group were significantly higher than those of the NZS group (P = 0.05). Milk zinc concentrations declined significantly over the course of the study for all subjects but were not affected by zinc supplementation. The mean dietary zinc intake observed in the nonsupplemented group was adequate to maintain normal maternal zinc status and milk zinc concentrations through > or = 7 mo lactation. Similar controlled intervention trials in less well-nourished populations will be required to assess the impact of lower zinc intakes on milk zinc concentrations.

Ex Output:
Zinc supplementation during lactation: effects on maternal status and milk zinc concentrations.

Now that we have a good understanding of the DNA double strand break (DSB) repair mechanisms and DSB-induced damage signalling, attention is focusing on the changes to the chromatin environment needed for efficient DSB repair. Mutations in chromatin remodelling complexes have been identified in cancers, making it important to evaluate how they impact upon genomic stability. Our current understanding of the DSB repair pathways suggests that each one has distinct requirements for chromatin remodelling. Moreover, restricting the extent of chromatin modifications could be a significant factor regulating the decision of pathway usage. In this review, we evaluate the distinct DSB repair pathways for their potential need for chromatin remodelling and review the roles of ATP-driven chromatin remodellers in the pathways.

Ex Output:
Roles of chromatin remodellers in DNA double strand break repair.

Octreotide, an effective treatment for acromegaly, induces gall bladder stones in 13-60% of patients. Because knowledge of stone composition is essential for studies of their pathogenesis, treatment, and prevention, this was investigated by direct and indirect methods in 14 octreotide treated acromegalic patients with gall stones. Chemical analysis of gall stones retrieved at cholecystectomy from two patients, showed that they contained 71% and 87% cholesterol by weight. In the remaining 12 patients, localised computed tomography of the gall bladder showed that eight had stones with maximum attenuation scores of < 100 Hounsfield units (values of < 100 HU predict cholesterol rich, dissolvable stones). Gall bladder bile was obtained by ultrasound guided, fine needle puncture from six patients. All six patients had supersaturated bile (mean (SEM) cholesterol saturation index of 1.19 (0.08) (range 1.01-1.53)) and all had abnormally rapid cholesterol microcrystal nucleation times (< 4 days (range 1-4)), whilst in four, the bile contained cholesterol microcrystals immediately after sampling. Of the 12 patients considered for oral ursodeoxycholic acid (UDCA) treatment, two had a blocked cystic duct and were not started on UDCA while one was lost to follow up. After one year of treatment, five of the remaining nine patients showed either partial (n = 3) or complete (n = 2) gall stone dissolution, suggesting that their stones were cholesterol rich. This corresponds, by actuarial (life table) analysis, to a combined gall stone dissolution rate of 58.3 (15.9%). In conclusion, octreotide induced gall stones are generally small, multiple, and cholesterol rich although, in common with spontaneous gall stone disease, at presentation some patients will have a blocked cystic duct and some gall stones containing calcium.

Ex Output:
Composition of gall bladder stones associated with octreotide: response to oral ursodeoxycholic acid.
