The main cause can be traced back to an irregular or absent ...

Introduction I read with great interest the contribution of Maleki et al. entitled ”Normal range of bleeding time in urban and rural areas of Borujerd, west of Iran” that has been published in recent issue of ARYA Atherosclerosis. The bleeding time test (BTT) is an old invivo test for evaluation of platelets function and vascular integrity with low producibility. Its procedure and performance i...

Background. Coexistence of iron deficiency anemia (IDA) and beta thalassemia trait (BTT) has been the topic of few studies. However, no study from our country was found evaluating the effect of iron therapy in patients with concomitant IDA and BTT. Methods. Over a period of two years, 30 patients with concomitant IDA and BTT were included. All the patients had a complete blood count, serum iron...

BACKGROUND The UK Department of Health funds ventricular assist device (VAD) implantation as a bridge to transplantation (BTT) at three centers. The cost-effectiveness of this program has not been established. METHODS All 70 VAD implants for BTT and a consecutive cohort of 71 inotrope-dependent transplant candidates, between April 2002 and December 2004, were prospectively monitored for survi...

Tobacco smoke (TS) is a major cause of human bladder cancer (BC). Two components in TS, 4-aminobiphenyl (4-ABP) and acrolein, which also are environmental contaminants, can cause bladder tumor in rat models. Their role in TS related BC has not been forthcoming. To establish the relationship between acrolein and 4-ABP exposure and BC, we analyzed acrolein-deoxyguanosine (dG) and 4-ABP-DNA adduct...

Exchange of the guest Mn2+ ions in Mn3[(Mn4Cl)3(BTT)8(CH3OH)10]2 (1-Mn2+; BTT=1,3,5-benzenetristetrazolate) with selected cations results in the formation of isostructural framework compounds 1-M (M=Li+, Cu+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+). Similar to the parent compound, the new microporous materials are stable to desolvation and exhibit a high H2 storage capacity, ranging from 2.00 to 2.29 wt ...

This paper address the control problem for the bank-to-turn (BTT) missile, which is a complicated nonlinear system. BTT autopilot is not simple, mainly due to the nonlinear and coupled character of system equations, the lack of a precise model for the missile dynamics and parameters, as well as the appearance of internal and external perturbations. The proposed methodology is an approach includ...

The diagnosis of blade crack faults is critical to ensuring the safety turbomachinery. Blade tip timing (BTT) a non-contact vibration displacement measurement technique, which has been extensively studied for condition monitoring recently. fault methods based on deep learning can be summarized as studying internal logical relationship data, automatically mining features, and intelligently ident...
