Secondary Protein Aggregates in Neurodegenerative Diseases: Almost the Rule Rather than the Exception.

The presence of protein aggregates is a hallmark of many neurodegenerative diseases, including Parkinson's disease (PD), Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD). Traditionally, each disease has been associated with the aggregation of specific proteins, which serve as disease-specific biomarkers. For example, aggregates of α-synuclein (α-syn) are found in α-synucleinopathies such as PD, dementia with Lewy bodies (DLB), and multiple system atrophy (MSA).

Biological and therapeutic implications of RKIP in Gastrointestinal Stromal Tumor (GIST): an integrated transcriptomic and proteomic analysis.

Background: Gastrointestinal stromal tumors (GIST) represent a significant clinical challenge due to their metastatic potential and limited treatment options. Raf kinase inhibitor protein (RKIP), a suppressor of the MAPK signaling pathway, is downregulated in various cancers and acts as a metastasis suppressor. Our previous studies demonstrated low RKIP expression in GIST and its association with poor outcomes.

Spontaneous intracerebral haemorrhage associated with early-onset cerebral amyloid angiopathy and Alzheimer's disease neuropathological changes five decades after cadaveric dura mater graft.

Cerebral amyloid angiopathy (CAA) is a small vessel disease, causing spontaneous intracerebral hemorrhage (ICH) in the elderly. It is strongly associated with Alzheimer disease (AD), as most CAA patients show deposition of Aβ-i.e.

DNA Recovery Using Ethanol-Based Liquid Medium from FTA Card-Stored Samples for HPV Detection.

Introduction: Alternative methods of dry storage and transportation may be a viable alternative to the use of liquid storage medium for cervical samples, especially for screening programs in places with few resources.

Objective: The objective of this study is to verify the viability and efficacy of human papillomavirus DNA (HPV-DNA) detection in cervical cell samples collected and stored on a Flinders Technology Associates (FTA) card (Whatman Indicating FTA® Elute Micro Card) and subsequently recovered in ethanol-based liquid medium and to compare the results to those obtained using samples stored directly in ethanol-based liquid medium.

Study Design: Thirty-four women submitted to ETZ (excision of the transformation zone of the cervix) were included in this study.

Human papillomavirus genotyping as a tool for cervical cancer prevention: from commercially available human papillomavirus DNA test to next-generation sequencing.

The biological importance of human papillomavirus (HPV) in the field of medicine - related to cervical carcinogenesis - has been extensively reported in the last decades. For the first time, a direct correlation between cause and effect to explain a cancer development was completely achieved in medical research. Consequently, the Nobel Prize was awarded to HZ Hausen in 2008 for his efforts to understand the effects of persistent infection of oncogenic types of HPV and malignancy transformation.
