Dynamic frothability index (DFI) is a characteristic of any frother which presents useful information about frothing properties. The objective of this study is to introduce a prediction model for estimation of DFI value of dual-frother blends. Model uses the DFIs of frothers and mole ratio of weaker frother to calculate the blend’s DFI. The model reliability was confirmed by comparing the exper...

OBJECTIVE This retrospective, single-center study was designed to distinguish severe diabetic foot infection (DFI) from moderate DFI based on the presence or absence of systemic inflammatory response syndrome (SIRS). RESEARCH DESIGN AND METHODS The database of a single academic foot and ankle program was reviewed and 119 patients were identified. Severe DFI was defined as local infection asso...

BACKGROUND We assessed sperm DNA fragmentation index (DFI) in cancer patients before and after treatment to evaluate if sperm DNA integrity is compromised by cancer itself or its treatment. METHODS In a prospective study, DFI was assessed in 127 patients diagnosed with testicular germ cell tumours (TGCT), Hodgkin's lymphoma (HL), non-Hodgkin's lymphoma (NHL) and various malignancies. The seve...

BACKGROUND There is considerable uncertainty as to the significance of a high sperm DNA fragmentation index (DFI) for achieving a successful pregnancy. METHODS The sperm DFI of 124 patients undergoing 192 IVF cycles and of 96 patients undergoing 155 ICSI cycles was determined using the sperm chromatin structure assay on neat sperm. RESULTS The rate of continuing pregnancies in ICSI cycles (...

BACKGROUND We evaluated the impact of testicular germ cell cancer (TGCC), its treatment and length of follow-up on sperm DNA integrity. METHODS In 96 TGCC patients, semen was collected at specific intervals until 5 years after treatment. Sperm DNA integrity was assessed by the sperm chromatin structure assay (SCSA, n = 193) and by the terminal deoxynucleotidyl transferase-mediated dUTP nick-e...

Little information exists about boar sperm chromatin quality and fertility within a commercial setting. The objective of this report is to provide information about boar sperm chromatin integrity and its relationship to fertility. The sperm chromatin structure assay (SCSA) was used retrospectively to characterize sperm from 18 sexually mature boars having fertility information. Boar fertility w...

The displacement- and frequency-noise-free interferometer (DFI) is a multiple laser interferometer array for gravitational-wave detection free from both the displacement noise of optics and laser frequency noise. So far, partial experimental demonstrations of the DFI have been done in 2D table top experiments. In this Letter, we report the complete demonstration of a 3D DFI. The DFI consists of...

Daily feed intake (DFI) is an important consideration for improving feed efficiency, but measurements using electronic feeder systems contain many missing and incorrect values. Therefore, we evaluated three methods for correcting missing DFI data (quadratic, orthogonal polynomial, and locally weighted (Loess) regression equations) and assessed the effects of these missing values on the genetic ...

Objective: To investigate the effect of sperm DNA fragmentation index (DFI) on the clinical outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods: Infertile couples were prospectively recruited in the Reproductive Center in Jiaozuo Maternal and Child Care Service Centre in Henan, China, from July 2015 to December 2016. All the recruited 228 infertile coup...
