OBJECTIVES This study sought to assess the impact of permanent pacemaker (PPM) implantation on clinical outcomes among patients undergoing transfemoral transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI is associated with atrioventricular-conduction abnormalities requiring PPM implantation in up to 40% among patients treated with self-expanding prostheses. METHODS Between 2007 ...
The aim of this study was to assess the heavy metal content of the dust generated by the Sagamu cement factory and its attendant health hazards on the immediate environment, especially on the inhabitants of the area. A total of 25 samples were collected and analyzed using inductively coupled plasma-optical emission spectrometry. Records of medical ailments associated with heavy metal toxicity w...
Contents of inorganic elements are very important traits in plants. Some of elements have causal effects on plant growth. Their effects on plant metabolism and therefore quality and quantity of essential oils is crucial. Thus, to obtain relatively good results, different parts of Rosa damascena Mill. genotypes were analyzed. Plants were collected from different provinces including Tehran, East ...
Background and purpose: Treatment and disposal Septage in developed countries is subject to strict regulations and standards, but in most developing countries, there is no decent standard. Septage if not treated properly can create many problems. This quantitative and qualitative study of urban Septage was done in East Mazandaran (Sari, Behshahr, Neka and Galogah) to provide administrative appr...
conclusions results of this study suggest that the extract alone of peganum harmala and heracleum persicum may be useful to treat bacterial infections. objectives the major aim of the current study was to investigate the antimicrobial activity of an extract of the peganum harmala flower and heracleum persicum against acinetobacter baumannii. materials and methods the minimum inhibitory (mic) co...
The study area is located northwest of Iran (38 km SW of Qorveh); which is a part of Sanandaj-Sirjan Zone. The lithology of this pegmatite complex varies from pegmatitic syenogranite to granodiorite, which were intruded in the dolomitic marbels of the area. Field observation, thin sections studies, XRD, XRF and ICP analyses on minerals and rocks in the area show that the composition of these pe...
The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
Megafaunas worldwide have been decimated during the late Quaternary. Many extirpated species were keystone species, and their loss likely has had large effects on ecosystems. Therefore, it is increasingly considered how megafaunas can be restored. The horse (Equus ferus) is highly relevant in this context as it was once extremely widespread and, despite severe range contraction, survives in the...
