Six men were subjected to 3500 Hertz pure tones of 1250 millisecond pulse length repeated every 2. 5 seconds for a period of 15 minutes at Sound Pressure Levels of 168 and 178 decibels re .0002 dynes per square centimeter. Temporary Threshold Shifts were measured and compared to temporary threshold shifts induced by similar exposures at lower levels in air in a second group of five men. It was ...
BACKGROUND We explored the expression pattern, prognostic potential, and functional role of microRNA-588 (miR-588) in human breast cancer (BC). MATERIAL AND METHODS The expression pattern of miR-588 was assessed by qPCR in BC cell lines and human BC carcinomas. The correlations between miR-588 and BC patients' clinicopathological characteristics, as well as BC patients' overall survival, were s...
OBJECTIVE Feeding bovine colostrum (BC) improves gut maturation and function and protects against necrotizing enterocolitis, relative to formula in newborn preterm pigs. Before BC can be used for preterm infants, it is important to test if the milk processing, required to reduce bacterial load and increase shelf life, may affect bioactivity and efficacy of a BC product. METHODS We investigate...
B-Crystallin ( BC), a small heat shock protein expressed in high levels in the heart, is phosphorylated on Ser-19, 45, and 59 after stress. However, it is not known whether BC phosphorylation directly affects cell survival. In the present study, constructs were prepared that encode forms of BC harboring Ser to Ala (blocks phosphorylation) or Ser to Glu (mimics phosphorylation) mutations at posi...
UNLABELLED Breast cancer (BC) in young adult patients (YA) has a more aggressive biological behavior and is associated with a worse prognosis than BC arising in middle aged patients (MA). We proposed that differentially expressed miRNAs could regulate genes and proteins underlying aggressive phenotypes of breast tumors in YA patients when compared to those arising in MA patients. OBJECTIVE Us...
The morphology and density of black carbon (BC) cores in internally mixed BC (In-BC) particles affect their mixing state and absorption enhancement. In this work, we developed a new method to measure the morphology and effective density of the BC cores of ambient In-BC particles using a single-particle soot photometer (SP2) and a volatility tandem differential mobility analyzer (VTDMA) during t...
