In silico screening of 10,143 metal-organic frameworks (MOFs) and 218 all-silica zeolites for adsorption-based and membrane-based He and N separation was performed. As a result of geometry-based prescreening, structures having zero accessible surface area (ASA) and pore limiting diameter (PLD) less than 3.75 Å were eliminated.

Materials And Methods: The NSCLC A549 cell line was treated with cisplatin (0.2 μg/ml), vinorelbine (2 nM), VPA (1 mM) and IR (2.
Kidneys play an important role in retinol turnover. We postulated that retinol homeostasis is disturbed in diabetic nephropathy. The aim of this research was to study the effect of kidney impairment on urinary excretion and on serum concentrations of retinol in type 2 diabetes mellitus patients.

However, effective doses of ionizing radiation (IR) have a high risk of side effects. To increase sensitivity of PCa to IR we pretreated human androgen-refractory DU145 PCa cells with a combination of sodium valproate (VPA), a well-tolerated drug with histone deacetylases inhibiting activity, and 1,25-dihydroxyvitamin D3, 1,25(OH)2D3, the active metabolite of vitamin D, a well known anticancer agent.

The effect of treating the androgen-resistant PCa cell line DU145 with a combination of the anti-EGFR drug cetuximab and 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) was evaluated.
Materials And Methods: DU145 cells were treated with 5 nM cetuximab, 100 nM 1,25(OH)2D3 or a combination of both.
Background: The active metabolite of vitamin D3, 1,25(OH)2D3, is known to possess anti-proliferative and pro-differentiative activities in prostate cancer (PCa) cells. However, its clinical use is limited because of the risk of hypercalcemia. Concurrent administration of lower doses of 1,25(OH)2D3 together with other anticancer drugs may help to overcome this obstacle and lead to an effective and tolerable therapy.

Background: Many medications prescribed to children worldwide have not been approved for pediatric use because the necessary clinical trials have not yet been performed. Children given these drugs have been shown to be at increased risk for adverse drug reactions.
Objective: The aim of this study was to assess the extent of unapproved (off label and/or unlicensed) use of medications in pediatric intensive care units (PICUs) in Israel.
Urinary excretion of vitamin A was studied in patients with multiple myeloma (MM). Eight of the 12 patients studied excreted retinol in urine; only one of them had elevated serum creatinine (115-150 micromol/L). There was a highly significant correlation between urinary retinol and serum creatinine (P < 0.

The formulations currently available have been designed for oral and rectal administration. However, they are not practical in young patients with vomiting and diarrhoea, or in those who refuse to take the full dose.

Here, we examined whether these beneficial effects of LF 16-0687 Ms are altered when CHT is accompanied by acute ethanol administration.
Methods: Six groups of rats (n = 8 per group) were examined during combination of the following experimental conditions: CHT versus sham operation, LF 16-0687 Ms 3 mg/kg subcutaneously versus saline, and ethanol 2 g/kg versus saline.
