Grandparent caregiving in Cambodian skip-generation households: Roles and impact on child nutrition.

This study aims to understand nutrition-related roles, responsibilities and ethical issues of grandparents caring for their grandchildren in skip-generation households in rural Cambodia. Over the past decade, Cambodia has experienced a rise in economic migration of working age populations. This has resulted in increasing numbers of 'skip-generation' households, in which grandparents and grandchildren co-reside without parents, reflecting potential household vulnerability.

ARGONAUTE PIWI domain and microRNA duplex structure regulate small RNA sorting in Arabidopsis.

Small RNAs (sRNAs) are loaded into ARGONAUTE (AGO) proteins to induce gene silencing. In plants, the 5'-terminal nucleotide is important for sRNA sorting into different AGOs. Here we show that microRNA (miRNA) duplex structure also contributes to miRNA sorting.

[Blood coagulation disorders of circulation in the transplant and their prevention in small intestine esophagoplasty].

An analysis of 158 completed esophagoplastics has shown that necroses of the transplant made their appearance in 7.8% of cases, fistulas of anastomoses--in 38%. The basis of pathogenesis of these complications is microthromboses of venules and small veins of the intramural blood circulation of the mobilized small intestine transplant (syndrome of local hypercoagulation).

[Palliative resection of the esophagus in cancer].

The clinico-morphological analysis of patients subjected to resection of the esophagus for cancer has shown palliative operations to be fulfilled in 26,9% of cases. Among the causes the first place is occupied by operations inadequate to the local, then metastatic and lastly intraorganic spread of tumor. The analysis of remote results shows little efficiency of such interventions and their expediency.

[Indications for the surgical and combined treatments of cancer of the thoracic portion of the esophagus].

Remote results of the surgical treatment of 120 patients and combined treatment (radiotherapy and surgery) of 43 patients with carcinoma of the oesophagus have been studied. Results of the treatment of groups of patients with the similar prognosis based on the quantitative assessment of unfavourable influence of such factors as the tumor, patient's organism and treatment are compared.
