Two case histories are presented documenting structural chromosome abnormalities in infertile males. The abnormalities were detected only after application of intracytoplasmic sperm injection (ICSI) was repeatedly unsuccessful or resulted in an abnormal pregnancy. A mosaic Robertsonian translocation 45,XY,der(13;13)(q10; q10)/46,XY,t(13;13)(p10;p10), der(13p;13p) incompatible with normal offspr...

[1] Temperature sensitivity of soil respiration (Q10) is an important parameter in modeling effects of global warming on ecosystem carbon release. Experimental studies of soil respiration have ubiquitously indicated that Q10 has high spatial heterogeneity. However, most biogeochemical models still use a globally constant Q10 in projecting future climate change, partly because no spatial pattern...

Robertsonian translocations (RT’s) are present in 0.1% of the general population and 1% of the infertile population. Two types of RT’s occur more frequently than all others, being 45,XX,rob(13;14)(q10;q10) and 45,XX,rob(14;21)(q10;q10) respectively. In the present report, an uncommon RT in a female with spontaneous repeated abortions is reported. Cytogenetic analysis of a couple with repeated a...

BACKGROUND High oxidative stress and chronic inflammation can contribute to the pathogenesis of coronary artery disease (CAD). Coenzyme Q10 is an endogenous lipid-soluble antioxidant. Statins therapy can reduce the biosynthesis of coenzyme Q10. The purpose of this study was to investigate the effects of a coenzyme Q10 supplement (300 mg/d; 150 mg/b.i.d) on antioxidation and anti-inflammation in...

OBJECTIVE The purpose of this study was to investigate the effect of coenzyme Q10 supplementation on oxidative stress and antioxidant enzyme activity in patients with coronary artery disease (CAD). METHODS This was an intervention study. Patients who were identified by cardiac catheterization as having at least 50% stenosis of one major coronary artery or receiving percutaneous transluminal c...

Ubiquinone (coenzyme Q10, Q10) represents an endogenously synthesized lipid-soluble antioxidant which is crucial for cellular energy production but is diminished with age and under the influence of external stress factors in human skin. Here, it is shown that topical Q10 treatment is beneficial with regard to effective Q10 replenishment, augmentation of cellular energy metabolism, and antioxida...

زمینه و هدف: کشتی ورزشی برخوردی با انقباض‌های برون‌گرای مکرر شدت بالاست. چنین فعالیت‌هایی که شدید انجام می‌گیرد، اختلالات مکانیکی متابولیکی همراه است. بالایی از فعالیت در به‌طور چشمگیری به تولید ناگهانی گونه‌های اکسیژن واکنش‌پذیر بنیان‌های آزاد حین رقابت بازیافت پس هر مسابقه منجر می‌شود، به‌طوری‌که حتی ممکن است طی این دسته فعالیت‌ها، ذخیرة ضداکسایشی به‌شدت کاسته تخلیه شود به‌دنبال ناکارامدی دست...

The impact of aging and physical capacity on coenzyme Q10 (Q10) levels in human blood is unknown. Plasma Q10 is an important factor in cardiovascular diseases. To understand how physical activity in the elderly affects endogenous Q10 levels in blood plasma, we studied a cohort of healthy community-dwelling people. Volunteers were subjected to different tests of the Functional Fitness Test Batte...

How to assess the temperature sensitivity (Q10 ) of soil organic matter (SOM) decomposition and its regional variation with high accuracy is one of the largest uncertainties in determining the intensity and direction of the global carbon (C) cycle in response to climate change. In this study, we collected a series of soils from 22 forest sites and 30 grassland sites across China to explore regi...
