OBJECTIVE: Level of serum homocysteine is remarkably common among patients with moderate to sever renal failure. We assessed whether serum homocysteine concentrations were correlated with proteinuria in overt diabetic nephropathy. MATERIALS AND METHODS: A cross-sectional study was carried out on 45 patients (29 males, 16 females) with overt proteinuria. All subjects had type 2 diabetes. Data i...

In general, joints are assumed without clearance in the dynamic analysis of multi-body echanical systems. When joint clearance is considered, the mechanism obtains two uncontrollable degrees of freedom and hence the dynamic response considerably changes. The joints’ clearances are the main sources of vibrations and noise due to the impact of the coupling parts in the joints. Therefore, the syst...

Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...

cystatin c is a 13 kd basic protein that is a member of the cystatin superfamily of cysteine protease inhibitors. the cystatin c gene seems to be a house keeping gene, which is compatible with a stable production rate of cystatin c by most cells. this protein is freely filtered through the glomerulus and almost completely reabsorbed and catabolized by proximal tubular cells. because of these ch...

The nasal cavity possesses many advantages as a site for drug delivery, such as, ease of administration, applicability for long term treatments and a large surface area for absorption. One important limiting factor for nasal drug delivery is the limited time available for absorption within the nasal cavity due to mucociliary clearance. Several drug delivery systems including different kinds of ...

successful clearance of hepatitis b virus (hbv) is a promising event in which host's immune system will attempt to get rid of the virus. the immunological events of hbsag seroclearance have attracted great attention in both natural history investigations and therapeutic trials. recent genome-wide association studies (gwas) has confirmed polymorphisms in the human leukocyte antigen (hla)-dp locu...

peanuts, an oilseed crop, contain about 46% oil. the peanut shell can be used as fuel or pallets and its dry matter as feedstuff. the whole pods consist of 1-6 kernels. shelling is done at harvest time when the pod moisture content is 5-10%. in this research, a peanut sheller was designed and developed to separate the shell from the pod. the sheller included a hopper, sheller cylinder, concave,...

as one of the most promising distributed generation (dg) sources, wind power technology has been widely developed in recent years. doubly fed induction generator (dfig) is currently employed as one of the most common topologies for wind turbine generators (wtgs). this generator operates as a synchronous/asynchronous hybrid generators. therefore, it is necessary to power engineers find understan...
