The aim of this paper was to assess the effect of catechol (CH), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (HQC), as a bacterial inhibitor, on keeping the quality of Gerbera Jamesonii cv. Hongyan cut flowers, known to be limited by vascular occlusion. Blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. The results showed th...

In order to investigate H2 rich blowout limit at different blockage ratios and flow velocities, a CFD software FLUENT was used to simulate H2 burning flow field in bluff-body burner, and the software CHEMKIN was adopted to analyze the sensitivity of each elementary reaction. Composition Probability Density Function C-PDF model was adopted to simulate H2 combustion field in turbulence flame. The...

OBJECTIVES This study aimed to evaluate subjective symptom changes in obstructive sleep apnoea hypopnea syndrome patients following nasal surgery, and to explore treatment efficacy in improving patient quality of life. METHODS Patients with nasal blockage accompanied by habitual snoring were stratified into four groups. Their subjective symptoms were evaluated before and after nasal surgery. ...

Various DNA sequences that interfere with transcription due to their unusual structural properties have been implicated in the regulation of gene expression and with genomic instability. An important example is sequences containing G-rich homopurine-homopyrimidine stretches, for which unusual transcriptional behavior is implicated in regulation of immunogenesis and in other processes such as ge...

., When designing a reflector Impulse Radiating Antenna, one must choose an appropriate feed impedance. Using the simplest approximations valid for high feed impedances, one finds that lower feed impedances are always prcfcrablc. However, low feed impedances imply thick feed arms, which incrcasc feed blockage for many designs, thus reducing the radiated field. Low feed impedances also lead to a...

CONCLUSION Blockage of the endolymphatic duct is a significant finding in Meniere's disease. The position of the utriculo-endolymphatic valve (UEV) and blockage of the ductus reuniens in the temporal bones were not found to be directly indicative of Meniere's disease. OBJECTIVE Comparison of blockage of the longitudinal flow of endolymph between ears affected by Meniere's disease and normal e...

Line-of-sight link blockages represent a key challenge for the reliability and latency of millimeter wave (mmWave) terahertz (THz) communication networks. To address this challenge, paper leverages mmWave LiDAR sensory data to provide awareness about environment proactively predict dynamic before they occur. This allows network make proactive decisions hand-off/beam switching, enhancing latency...

Elucidating molecular mechanisms by which lipids regulate protein function within biological membranes is critical for understanding the many cellular processes. Recently, we have found that dimeric αβ-tubulin, a subunit of microtubules, regulates mitochondrial respiration by blocking the voltage-dependent anion channel (VDAC) of mitochondrial outer membrane. Here, we show that the mechanism of...

BACKGROUND We assessed the results and impact of blockage of utero-ovarian anastomoses (UOA) on clinical outcome in women treated by laparoscopic uterine artery occlusion for uterine fibroids. METHODS Between 2004 and 2005, we prospectively analyzed the clinical data for 23 laparoscopic uterine artery occlusion cases combined with blockage of utero-ovarian anastomoses (Group A) and 67 laparos...

BACKGROUND Controlled ovarian hyperstimulation and intrauterine insemination (IUI) cycle is an ideal protocol for some subfertile patients. So, we decided to try this therapeutic protocol for the patients with unilateral tubal blockage diagnosed by hysterosalpingography (HSG). OBJECTIVE To evaluate the effect of unilateral tubal blockage diagnosed by HSG on cumulative pregnancy rate (CPR) of ...
