Detection of fungal sequences in human brain: rDNA locus amplification and deep sequencing.
Sci Rep
December 2024
Department of Medical Microbiology, Radboudumc, Nijmegen, The Netherlands.
The aetiology of Alzheimer's disease (AD) and Parkinson's disease (PD) are unknown and tend to manifest at a late stage in life; even though these neurodegenerative diseases are caused by different affected proteins, they are both characterized by neuroinflammation. Links between bacterial and viral infection and AD/PD has been suggested in several studies, however, few have attempted to establish a link between fungal infection and AD/PD. In this study we adopted a nanopore-based sequencing approach to characterise the presence or absence of fungal genera in both human brain tissue and cerebrospinal fluid (CSF).

Decoding states of consciousness from brain activity is a central challenge in neuroscience. Dynamic functional connectivity (dFC) allows the study of short-term temporal changes in functional connectivity (FC) between distributed brain areas. By clustering dFC matrices from resting-state fMRI, we previously described "brain patterns" that underlie different functional configurations of the brain at rest.

Porphyria is a rare and often underdiagnosed metabolic disorder that leads to abdominal pain, pelvic pain, changes in neurological states, and digestive issues due to a buildup of porphyrins in the body. Diagnosis can be especially difficult in young women, where symptoms of porphyria often overlap with gynecological conditions. We present a case of a 37-year-old female patient who was experiencing persistent lower abdominal and pelvic pain, brain fog and confusion, and a rash after long sun exposure.

Background: Entropy quantifies the level of disorder within a system. Low entropy reflects increased rigidity of homeostatic feedback systems possibly reflecting failure of protective physiological mechanisms like cerebral autoregulation. In traumatic brain injury (TBI), low entropy of heart rate and intracranial pressure (ICP) predict unfavorable outcome.

Nucleoredoxin (NXN) is a prominent oxidoreductase enzyme, classified under the thioredoxin family, and plays a pivotal role in regulating cellular redox homeostasis. Although the functional characterization of NXN has been extensively studied in mammals, its role in fish remains relatively unexplored. In this study, the NXN gene from Planiliza haematocheilus (PhNXN) was molecularly and functionally characterized using in silico tools, expression analyses, and in vitro assays.
