[Selenium (Se)uptake and transformation mechanisms and physiological function in plant: A review].

Selenium (Se) is an essential nutrient for many organisms, including microbe, animal and human, but the Se uptake and transformation mechanisms and physiological roles in plant still are controversial until now. Se could improve the growth and tolerance of plant at an appropriate le-vel, but could be toxic at higher levels. Research concerning Se uptake and metabolism in plant were promoted by Se biofortification and Se phytoremediation induced by the issues of Se deficiency in food and Se pollution in special areas.

Effect of bed width on the quality of compressions in simulated resuscitation: a randomized crossover manikin study.

Objectives: To investigate the effects of bed width on the quality of chest compressions during simulated in-hospital resuscitation.

Methods: Each candidate performed two 2-minute cycles of compression-only cardiopulmonary resuscitation on an adult manikin placed on either an emergency stretcher (narrow bed) or a standard hospital bed (wide bed) in random order at 1 day intervals. We conducted subjective assessments of cardiopulmonary resuscitation quality and rescuer fatigue at the end of each session, using surveys.

Up-down hand position switch may delay the fatigue of non-dominant hand position rescuers and improve chest compression quality during cardiopulmonary resuscitation: a randomized crossover manikin study.

Previous studies have shown improved external chest compression (ECC) quality and delayed rescuer fatigue when the dominant hand (DH) was in contact with the sternum. However, many rescuers prefer placing the non-dominant hand (NH) in contact with the sternum during ECC. We aimed to investigate the effects of up-down hand position switch on the quality of ECC and the fatigue of rescuers during cardiopulmonary resuscitation (CPR).

Kaempferol pretreatment modulates systemic inflammation and oxidative stress following hemorrhagic shock in mice.

Background: Kaempferol has been reported as beneficial for both acute and chronic inflammatory diseases. This study aims to investigate whether kaempferol affects systemic inflammation and oxidative stress in the heart, lung, and liver after hemorrhagic shock in mice.

Methods: Male C57/BL6 mice underwent hemorrhagic shock (mean arterial pressure of 35 mmHg for 90 min) and were arbitrarily divided into Sham, hemorrhagic shock (HS), and Kae groups (n = 10 in each group).

Dual-phase 99mTc-MIBI imaging findings in sporadic primary hyperplasia of parathyroid glands.

Primary hyperplasia of parathyroid is uncommon and rarely documented in literatures. We report an 18-year-old female patient with hyperparathyroidism due to unifocal primary hyperplasia of parathyroid glands. Dual-phase Tc-MIBI imaging was performed for this patient.

Protective effects of lipoxin A4 in testis injury following testicular torsion and detorsion in rats.

Purpose: To investigate the protective effects of lipoxin A4 (LXA4) in rat testis injury following testicular torsion/detorsion.

Methods: A rat testicular torsion model has been established as described. Rats were randomly divided into 6 groups: sham group, torsion group, torsion/detorsion (T/D) group, and T/D plus LXA4-pretreated groups (3 subgroups).

The MTHFR C677T polymorphism and prostate cancer risk: new findings from a meta-analysis of 7306 cases and 8062 controls.

Methylenetetrahydrofolate reductase (MTHFR) is an essential enzyme involved in folate metabolism; a single nucleotide polymorphism (SNP) C677T has been reported to be linked with altered incidences of several diseases. We here conducted a meta-analysis of 15 published epidemiological studies with a total of 7306 cases and 8062 controls to evaluate its association with prostate cancer risk with overall and subgroup analyses. No statistical relationship was found overall with any genetic model (TT vs.

Expression patterns of ER, HER2, and NM23-H1 in breast cancer patients with different menopausal status: correlations with metastasis.

Objective: This study was designed to analyze expression patterns of estrogen receptor (ER), human epidermal growth factor receptor-2 (HER2/ERBB2), and nonmetastatic protein 23 (NM23-H1/NME1) proteins in patients with invasive ductal carcinoma and different menopausal status to identify their relationships with axillary lymph node metastasis.

Materials And Methods: 213 pre-menopausal and 177 post-menopausal women diagnosed with invasive ductal carcinoma were evaluated for ER, HER2, and NM23-H1 protein expression by immunohistochemistry. When HER2 immunoreactivity was equivocal (category 2+), specimens were confirmed by fluorescence in situ hybridization.

Cloning and expression pattern of a spermatogenesis-related gene, BEX1, mapped to chromosome Xq22.

Through screening a human fetal brain cDNA library, a cDNA similar to the mouse Bex1 was isolated. This new gene was named brain expressed X-linked protein 1 (BEX1). Northern blot analysis revealed a 1.
