The objective of this study was to evaluate the reproductive risk associated with exposure of adult male Fisher-344 rats to inhaled benzo(a)pyrene (BaP), a ubiquitous environmental toxicant present in cigarette smoke, automobile exhaust fumes and industrial emissions. Rats were assigned randomly to a treatment or control group. Treatment consisted of sub-chronic exposure of rats via inhalation ...
Benzo(a)pyrene (BaP) is a carcinogenic polycyclic aromatic hydrocarbon for human tissues. Still today it is not fully investigated if BaP can affect negatively the male fertility through the BaP‑DNA adducts production. In the present study, BaP Tetrol I‑1 (TI‑1) and BaP Tetrol II‑2 (TII‑2) BaP‑DNA adducts were investigated in spermatozoa of a Sicilian male population. Semen samples from 86 volu...
Human lung cells (ChaGo) derived from a bronchogenic carcinoma synthesize and secrete in the culture medium the alpha subunit of the glycoprotein hormone, human chorionic gonadotropin (alpha-hCG). The synthesis of alpha-hCG by ChaGo cells could be further stimulated by treatment with sublethal concentrations of the polycyclic aromatic hydrocarbons (PAHs), benzo(a)pyrene (BaP), or dimethylbenzan...
Plasma total versus bone alkaline phosphatase as markers of bone turnover in hemodialysis patients. Plasma bone-specific alkaline phosphatase (bAP) has been demonstrated to be more reliable than total alkaline phosphatases (tAP) in providing information about bone turnover in patients with metabolic bone diseases. This study surveyed 42 hemodialysis patients who underwent a systematic transilia...
Bap (biofilm-associated protein) is a 254-kDa staphylococcal surface protein implicated in formation of biofilms by staphylococci isolated from chronic mastitis infections. The presence of potential EF-hand motifs in the amino acid sequence of Bap prompted us to investigate the effect of calcium on the multicellular behavior of Bap-expressing staphylococci. We found that addition of millimolar ...
بهمنظور بررسی اثر کاربرد خارجی هورمونهای مختلف رشد (iaa، ga3 و 6-bap) به همراه آب مقطر (شاهد) در مراحل مختلف رشد و نمو (برجستگیدوگانه، بوتینگ، ابتدای رشد دانه و بوتینگ + ابتدای رشد دانه) سنبله دو رقم گندم (ریژاو و آذر-2)، یک آزمایش دو ساله بهصورت فاکتوریل بر پایه طرح بلوکهای کامل تصادفی در سه تکرار تحت شرایط دیم در مزرعه تحقیقاتی پردیس کشاورزی و منابع طبیعی دانشگاه رازی اجرا گردید. نتایج آ...
a fast and simple modified quechers (quick, easy, cheap, rugged and safe) extraction method based on spiked calibration curves and direct sample introduction was developed for determination of benzo[a]pyrene (bap) in bread by gas chromatography-mass spectrometry single quadrupole selected ion monitoring (gc/ms-sq-sim). sample preparation includes extraction of bap into acetone followed by clean...
One of the main obstacles in providing quality potato seed tubers is long dormancy period seeds. A study that explores this has been carried out to elucidate response release and initiation sprouts differences tuber weight storage duration before immersion cytokinin (6-benzylaminopurine). The was conducted at warehouse UPT Horticulture Parent Seed Kutagadung Berastagi, Department Food North Sum...
The adherence of Staphylococcus aureus to soluble proteins and extracellular-matrix components of the host is one of the key steps in the pathogenesis of staphylococcal infections. S. aureus presents a family of adhesins called MSCRAMMs (microbial surface components recognizing adhesive matrix molecules) that specifically recognize host matrix components. We examined the influence of biofilm-as...
Smoking is a major risk factor for atherosclerosis. In this study, we evaluated the effects of benzo[a]pyrene (BaP, a prominent component of tobacco smoke) on the function and pro-inflammatory response of human endothelial progenitor cells (EPCs). EPCs were isolated from umbilical cord blood and treated with different concentrations (10, 20 and 50 µmol/l) of BaP. The proliferation, migration, a...
