Association between serum vitamin E and bacterial vaginitis in women: a cross-sectional study.

Introduction: Bacterial vaginitis (BV) is a common vaginal disease. Vitamin E has been shown to reduce BV by enhancing immune function, but no studies have analyzed the relationship between vitamin E and BV at different BMIs and ages.

Method: This study used 2242 participants from four cycles of NHANES 1999-2006 in American.

Asymmetric Low Temperature Bonding Structure with Thin Solder Layers Using Ultra-Thin Buffer Layer.

Asymmetric Cu to In/Sn bonding structure with Ni ultrathin buffer layer (UBL) on Cu side is investigated in this research. The usage of Ni UBL slows down intermetallic compound (IMC) formation during bonding. Asymmetric structure can separate electrical isolation and solder process to avoid interaction, which can prevent IMC formation during polymer curing.
