BACKGROUND Poor quality dried blood spot (DBS) specimens are usually rejected by virology laboratories, affecting early infant diagnosis of HIV. The practice of combining two incompletely-filled DBS in one specimen preparation tube during pre-analytical specimen processing (i.e., the two-spot method) has been implemented to reduce the number of specimens being rejected for insufficient volume. ...

Confocal microscopy is a three-dimensional (3D) imaging modality, but the specimen thickness that can be imaged is limited by depth-dependent signal attenuation. Both software and hardware methods have been used to correct the attenuation in reconstructed images, but previous methods do not increase the image signal-to-noise ratio (SNR) using conventional specimen preparation and imaging. We pr...

Exfoliative cytopathology (often referred to as non-gynaecological cytology) is an important part of the workload of all diagnostic pathology departments. It clearly has a role in the diagnosis of neoplastic disease but its role in establishing non-neoplastic diagnoses should also be recognised. Ancillary tests may be required to establish a definitive diagnosis. Clinical and scientific teamwor...

background: although, nontuberculous mycobacteria can cause disease in different organisms, they usually are not reported in most countries because scientists in general consider them as non-pathogens. but, increasing nontuberculous mycobacteria diseases occurrence has changed this belief. nevertheless, there is no meta-analysis review about prevalence of nontuberculous mycobacteria in iran. me...

PURPOSE The purpose of this study is to specify a simple procedure for a robust data conversion of radioactivity value between plastic scintillator (PL) and NaI scintillator (NaI) devices. MATERIALS AND METHODS The radioactivity estimate of 100 blood samples was measured by the two devices. The two radioactivities were plotted on the same graph. The least-squares method was applied to obtain ...

background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...
