Effects of intelligence and approximate number system on the non-symbolic division ability in preschoolers.

Recently, it has become evident that cognitive abilities such as the approximate number system (ANS), number knowledge, and intelligence affect individuals' fundamental mathematical ability. However, it is unclear which of these cognitive abilities have the greatest impact on the non-symbolic division ability in preschoolers. Therefore, in the present study, we included 4- to 6-year-old Korean preschoolers without prior formal education of division in order to test their ability to solve non-symbolic division problems, ANS acuity, and intelligence, and to determine the interrelationships among those functions ( = 38).

Adverse postnatal developmental effects in offspring from humidifier disinfectant biocide inhaled pregnant rats.

Inhalation exposure to polyhexamethylene guanidine phosphate (PHMG-P), one of the primary biocides used in humidifier disinfectants, caused a fatal pulmonary disease in Korea. Pregnant women were also exposed to PHMG-P, and subsequent studies showed that PHMG-P inhalation during pregnancy adversely affects their health and embryo-fetal development. However, the postnatal developmental effects after birth on prenatally PHMG-P-exposed offspring have not yet been investigated.

Dual Inhibition of P-gp and BCRP Improves Oral Topotecan Bioavailability in Rodents.

P-glycoprotein (P-gp) inhibition has been studied to overcome multidrug resistance in cancer chemotherapy but failed in clinical trials due to low/toxic effects. Recently, a dual modulation of transporters and natural derivatives have been examined to surmount this limitation. We examined breast cancer resistance protein (BCRP) inhibition in vitro and in vivo by P-gp inhibitors derived from natural compounds in previous studies.

Anticalcification effect of a combination of decellularization, organic solvents and amino acid detoxification on glutaraldehyde-fixed xenopericardial heart valves in a large-animal long-term circulatory model.

Objectives: We aimed to investigate the effect of a combination of anticalcification treatments, which were effective for preventing calcification in a small animal experiment, on glutaraldehyde-fixed xenopericardial valves using a large-animal long-term circulatory model.

Methods: Valved conduits were made of porcine pericardium as a leaflet and bovine pericardium as a conduit and were implanted into the right ventricular outflow tract of goats under cardiopulmonary bypass. The goats were divided into study (glutaraldehyde + combined anticalcification treatment, n = 6) and control (glutaraldehyde alone, n = 9) groups.
