The major pathological feature of Parkinson’s disease (PD) is a progressive loss of dopamine-producing neurons of the substantia nigra pars compacta (SNc), resulting in a reduction of dopamine (DA) content in the target field of these neurons, the striatum (STR). The present evidences suggest that female sex hormones may influence the onset and severity of PD symptoms. PD is more prevalent in m...

background and aims: infectious bronchitis (ib), caused by infectious bronchitis virus (ibv), is an acute and highly contagious disease in chickens. ibv is considered mainly as a respiratory infection, other clinical manifestations, including renal, enteric and reproductive signs can be observed. since there has been no study on evaluation of changes in biochemical parameters during ib infectio...

background: the internet addiction, also described as pathological internet use (piu), is conceptualized by an individual's in­ability to control his or her use of the internet, which eventually causes marked distress and/or functional impairment. the aim of the present study was to investigate the prevalence of the piu among adolescence, in relation to different internet ac­tivities, and to ex...

Constrained non-negative matrix factorization (CNMF) is an effective machine learning technique to cluster documents in the presence of class label constraints. In this work, we provide a novel application of this technique in research on neuro-degenerative diseases. Specifically, we consider a dataset of documents from the Netherlands Brain Bank containing free text describing clinical and pat...

introduction: cloacal malformation is an extremely rare fetal pathological condition but an important anomaly that presents as a variety of defects. it predominantly affects females, with prevalence of 1 in 50,000 births. prenatal ultrasonography usually showed oligohydramnios and the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous...

breast cancer is the most common type of cancer among women. the important key to treat the breast cancer is early detection of it because according to many pathological studies more than 80% of all abnormalities are still benign at primary stages; so in recent years, many studies and extensive research done to early detection of breast cancer with higher precision and accuracy.infra-red breast...

The clinical and pathological findings in 23 patients with ischaemic lesions of the alimentary tract (ischaemic enterocolitis) are described. These are compared with findings in 13 patients with occlusive thrombosis of the superior mesenteric artery. The pathological features distinguishing the two conditions are discussed. Ischaemic enterocolitis was found to be a relatively common condition (...

The hereditary spastic paraplegias are a group of neurodegenerative conditions that all share the principal clinical feature of progressive lower limb spastic paralysis, caused by either failure of development or progressive degeneration of the corticospinal tract. The conditions are characterised by extreme genetic heterogeneity, with at least 20 genes involved. Until recently, no functional o...
