Abstract. Alzheimer's disease is an extremely serious condition that is challenging to diagnose. We have used experimental data to compare the rate of decay of entorhinal cortex (EC) neurons in various stages of Alzheimer's. We observed that the rate of EC neuron decay in the patients without Alzheimer's is close to zero, linear in mild cases, and quadratic in severe cases. We believe that desc...

The rudimentary horn pregnancy (RHP) (incidence of 1/10,000 to 1/40,000) usually ends up in rupture of gravid horn in second or third trimester, leading to potentially fatal hemorrhage. Modern modalities can diagnose it in a very early pre-rupture stage, thus making medical management possible (1). Acute presentation at an early gestation is a very rare phenomenon. This case reports such an ear...

Laser-induced fluorescence at 337-nm excitation was used in vivo to differentiate neoplastic [cervical intraepithelial neoplasia (CIN)], nonneoplastic abnormal (inflammation and human papilloma viral infection), and normal cervical tissues. A colposcope (low-magnification microscope used to view the cervix with reflected light) was used to identify 66 normal and 49 abnormal (5 inflammation, 21 ...

AIM To evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer. METHODS Only EUS studies confirmed by surgery were selected. Articles were searched in Medline and Pubmed. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and ...

Quality control of textile products is an important stage in textile industries. To this end, the conventional method in fault detection is human inspection. In the present work, Wavelet transform was applied on images of simple circular knitted fabrics to diagnose five regular defects. The results showed that the method applied was accurate and fast in addition to being capable of determining ...

Alzheimer’s disease (AD) is a progressive, neurodegenerative disorder characterized by impairments in multiple cognitive domains and it is hard to diagnose in early stage because it’s not easy to recognize and develop slowly. In this study, we try to evaluate the difference of white matter between AD and health volunteers using diffusion tensor imaging (DTI) and try to provide some evidence for...

In stage V twin-twin transfusion syndrome (TTTS), up to 50% of surviving twins die or experience permanent disabilities, likely due to acute intertwin hemorrhage resulting in sudden severe anemia of the survivor. Although fetal middle cerebral artery (MCA) Doppler studies demonstrate strong correlation with fetal hemoglobin values, acute hemorrhagic events are more difficult to diagnose, and op...

Paranasal sinus malignancies are exceedingly rare. Chronic respiratory tract infections, nasal congestive symptoms and rhinosinusitis are much more prevalent in recent days and manifest many symptoms that overlap with those of sinus malignancy. Symptoms may be nonspecific and indolent for months or even years, leading to delay in diagnosis and consequent advanced diseased stage at presentation....

Introduction: Although more than 95% of breast cancers originate in the mammary ducts, clinicians cannot reliably diagnose cancers at this early intraductal stage. Magnetic resonance spectroscopy (MRS) can distinguish between benign and malignant tissue with specificity and sensitivity upwards of 80%. Unfortunately, conventional methods are limited to late-stage diagnosis, as cm of malignant ti...
