Identification of biological markers for neuropsychiatric disorders
… The positive correlation of these biochemical markers with the diagnosis of dementia and depression suggests the presence of a similar pathological 'pattern' underlying both disorders which is in agreement with the hypothesis of a common substrate of vascular pathology in both dementia and …

Biological Markers in First-Episode Schizophrenia /// Биологични маркери при първи шизофренен епизод
Шизофренията е психично разстройство, което се среща само при хомо сапиенс. Психотични симптоми са описвани в литературата от векове, но въвеждането на термина се реализира през 1911 г. от Ойген Блойлер в Швейцария. Нелек въпрос е дали шизофренията, както я познаваме сега, е съществувала в …

Using Multiple Biological Markers to Measure Sickle-Cell Disease Severity and Cognitive Risk
… deficits is critical for effective intervention. Biological measures of disease severity may serve as clinical markers of neurological complications; however the relationship between such markers and cognitive deficits in this population remains unclear. Mixed evidence for the relationship may …

Effect of allopurinol and hemin on some biological markers of aging in broiler chickens
Uric acid has been hypothesized as one of the most important antioxidants in limiting the accumulation of advanced glycolated endproducts in broiler breeder hens. This study was designed to quantitatively manipulate the plasma uric acid concentrations using hemin and allopurinol and determine its …

Exploring relationships between stress and olfaction as mediated by neuropeptide y
… and depression has been well documented, but the biological processes underpinning the relationship are not understood. This study explored a potential relationship between olfactory sensitivity, stress, and resilience to stress, specifically examining neuropeptide y (NPY) as a mediator. In phase …

The detection and treatment of alcohol dependence
… In healthy individuals and in clinical samples, biological markers showed early signs of the syndrome in healthy men. A comparison of Lothian general population data with Edinburgh hospital admission data showed that heavier alcohol consumption predicted admission to a general hospital bed. …

Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence.
… value of immunohistochemical (IHC) expression of biological markers is unclear. The tissue-preserving, high throughput tissue microarray (TMA) technique for analysis of immunohistochemical expression of biological markers was validated for Ki-67, and was found to yield results comparable to …

Longitudinal Visualization of Neurodegeneration: Digital Biopsy of the Retina
… isolated physiology of the eye, the classical markers of inflammation are not detectable in-vivo without an invasive biopsy. The major aims of this dissertation are to explore optical methods for a digital biopsy and demonstrate their utility in animal models of disease. In this dissertation, …

Neurodegenerative Biomarkers in Healthy Elderly - with special reference to the preclinical pattern of biological and cognitive markers for Alzheimer’s disease
… disorder has a long preclinical phase. Several biological markers for detecting and predicting AD have been validated over the years, where CSF biomarkers are one of the most recent and accurate markers. The generally perceived notion today is that these biological markers will be altered also …

Mathematical Models of Hepatitis B Virus Dynamics during Antiviral Therapy
… we will analyze this model to determine the biological markers (e.g. liver proliferation, immune responses, and drug efficacy) that determine the different decay patterns. We will also investigate how such markers affect the length of therapy and the amount of liver damage.

Detection of Nucleic Acid Disease Biomarkers Using Solid-State Nanopores
… has been achieved. While this device utilizes biological nanopores, Solid-State Nanopore sensors were also initially investigated to develop sequencing devices. Significant efforts are being made to this day towards this end, with advances and improvements being made to amplifiers and using …

Kent Kiehl’s Search for the Criminal Brain America’s self-proclaimed “psychopath whisperer” says he can predict criminality in incarcerated people. Is the legal system buying it?
… researchers have attempted to uncover the biological roots of criminality. The process has been both scientifically dubious and ethically fraught. While biological theories of criminal behavior faded after World War II, they arose again in the 1990s and early 2000s, when new brain imaging …

Neurophysiological evaluation of sensory gating and selective attention in schizotypal personality
… disorders. Investigations of biological markers for schizophrenia in schizotypal subjects have tried to test this relationship. Given that there is considerable evidence for both sensory gating and binaural selective attention abnormalities in schizophrenia, as reflected by …

GENOMIC AND EPIGENETIC APPROACHES IN THE CLINICAL AND PROGNOSTIC STRATIFICATION OF CHRONIC LYMPHOCYTIC LEUKEMIA
… The aim of the study is to identify novel biological markers that may be clinically relevant to envisage specific risk subgroups of CLL patients using both genomic (integrated FISH and microarray technology) and an epigenetic approach in highly purified B-cell populations obtained from …

The potential of epigenetic methods to provide evidence of torture
… types of torture is often a challenge. Finding biological markers of torture would potentially contribute to solve this problem.
 Methods: Scientific literature review.
 Results: Methods to analyse certain biological marks present in the genetic material (the DNA), called epigenetic …

Neural and Behavioral Evidence for a Link Between Mobile Technology Usage and Intertemporal Preference
… pathways that have been previously implicated as biological markers for individual differences in intertemporal preference. Regression analyses revealed that both pathways predicted delay discounting performance, but only vSTR-vmPFC predicted mobile technology engagement. Taken together, the …

Novel approaches to evaluate osteoarthritis in the rabbit lateral meniscectomy model
… of osteoarthritis and to identify possible biological markers. First, 21 male, New Zealand White rabbits were divided into 3 groups (n = 7 / group). A randomly selected left or right stifle underwent a lateral meniscectomy. The 3 groups were: corticosteroid administration, forced exercise …
