#1
E Jane Walter, Lothar Lilge
A 12-laser-wavelength, fixed source-detector position, cup-based optical breast spectroscopy (OBS) device was developed for use in large-scale, multi-center trials as a mammographic breast density (MBD) quantification and breast cancer risk pre-screening tool. In this study, the device was evaluated in comparison with a spectrometer-based device used in previous studies. The devices were compared on their ability to predict mammographic percent density (MPD) and to identify women with high MBD from optical spectra...

Supawon Srettabunjong
Suicidal intoxication from massive propranolol ingestion is rare. Surprisingly, no reported cases have involved physicians. The author herein reports a case of self-poisoning death due to ingestion of propranolol by a young male physician. A 31-year-old man with major depressive disorder was found dead in his dormitory room. Fifteen empty packages, each having contained ten 40-mg propranolol tablets, were found without any tablets leftover in his room. A suicide note was also found in his room. He was thus alleged to have ingested 6 g of propranolol for self-poisoning...

PRIMARY OBJECTIVE: Behaviours of Concern (BoC) following traumatic brain injury (TBI) have a significant negative impact on the daily functioning and quality of life for the individual and their family. However, there has been limited research examining the nature and severity of BoC beyond the acute recovery period, including the perspective of the individual with TBI as well as close others (COs). METHODS AND PROCEDURE: Eighty-nine individuals with predominantly severe TBI, at a mean of 11...

α2-antiplasmin (α2AP) is known to be a physiological inhibitor of plasmin. Previously, we showed that α2AP displays various functions, such as promotion of extracellular matrix production, cell growth, and cell differentiation that are not promoted by its function as a plasmin inhibitor. We herein investigated the role of α2AP in bone formation by examining calcein incorporation after its injection in α2AP-deficient mice. We found that α2AP deficiency enhanced the bone formation rate in mice. We also found that the osteocalcin expression and alkaline phosphatase activity were elevated in the femur and serum of the α2AP-deficient mice...

Human being is not spared from a broad-ranged emotional state, including being jealous. Jealousy has both affective-cognitive and behavioural-evaluative dimension where the person perceives, or experiences a real threat on a valued relationship. As this complex emotion becomes irrational and not amenable to reason, it later transforms into a dangerously 'green-eyed monster'. This perilous situation which is viewed as pathological jealousy is a form of delusion, which is maintained by a fixed and false reasoning in an originally entrusted intimate relationship...

This is one of the few examples in which the diverse products have been synthesized just by changing the applied potential. The synthesis of sulfonyl derivatives of p-methylaminophenol were carried out by reaction of the electrogenerated p-methylquinoneimine with sulfinic acids. Various types of mono (MSP), bis (BSP) and tris (TSP) sulfonyl p-methyl aminophenols were obtained by changing the electrode potential, in one pot under green conditions. The mono sulfonyl-p-(methylamino)phenol derivatives (MSP) were assessed for their in vitro antibacterial activity against the gram positive (Staphylococcus aureus) and gram negative (Escherichia coli) strains...

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative...

Training protocols designed to improve dual-task performance of an obstacle crossing and auditory Stroop task (OBS+Stroop) were tested. In Experiment  1 , following baseline collection of OBS+Stroop trials, proximally related walking training was performed, and participants were then retested on the OBS+Stroop test. After training, participants adopted a more cautious obstacle crossing strategy, indicating a potentially safer navigation strategy. Transfer effects from distally related training were then examined (Experiment  2 ); a computer game training paradigm was examined using the same testing protocol as Experiment  1 ...

Parkinson's disease (PD) is a neurodegenerative disease with both motor and non-motor manifestations. Hyposmia is one of the early non-motor symptoms, which can precede motor symptoms by several years. The relationship between hyposmia and PD remains elusive. Olfactory bulb (OB) pathology shows an increased number of olfactory dopaminergic cells, protein aggregates and dysfunction of neurotransmitter systems. In this study we examined tissue levels of dopamine (DA) and serotonin (5-hydroxytryptamine, 5-HT) and their metabolites, of noradrenaline (NA) and of the amino acid neurotransmitters aspartate, glutamate, taurine and γ-aminobutyric acid in OBs of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) treated Macaca fascicularis in different stages, including monkeys who were always asymptomatic, monkeys who recovered from mild parkinsonian signs, and monkeys with stable moderate or severe parkinsonism...

Eulimnadia Packard, 1874 is the most species rich and widely distributed genus within the Limnadiidae (Reed et al. 2015). Species identification relies primarily on egg morphology as adult morphological characters show high variability, sometimes within the same populations and hence of little use (Rabet, 2010; Rogers et al. 2012). Seven species are currently known from the Indian subcontinent (sensu Rogers & Padhye 2015) and SE Asia (Rogers et al. 2016). Of these, four species, viz. E. compressa (Baird, 1860), E...

Alzheimer´s disease (AD) is characterized by progressive dementia, initially presenting olfactory dysfunction. Despite the olfactory bulb (OB) is the first central structure of the olfactory pathway, we lack a complete molecular characterization of the transcriptional events that occurs in this olfactory area during AD progression. To address this gap in knowledge, we have assessed the genome-wide expression in postmortem OBs from subjects with varying degree of AD pathology. A stage-dependent deregulation of specific pathways was observed, revealing transmembrane transport, and neuroinflammation as part of the functional modules that are disrupted across AD grading...

Pure amnesia (amnesic syndrome) is an organic brain syndrome characterized by impairment in episodic memory, with either an anterograde or sometimes retrograde loss of memories. Although episodic memory is impaired, semantic memory, immediate memory, and procedural memory are preserved. The Papez circuit is a network of nerve fibers and nerve centers that starts and ends in the hippocampus travelling by way of the fornix, mammillary bodies, anterior thalamic nuclei, cingulate gyrus, and parahippocampal gyrus...

BACKGROUND: As crucial markers in identifying biological elements and processes in mammalian genomes, CpG islands (CGI) play important roles in DNA methylation, gene regulation, epigenetic inheritance, gene mutation, chromosome inactivation and nuclesome retention. The generally accepted criteria of CGI rely on: (a) %G+C content is ≥ 50%, (b) the ratio of the observed CpG content and the expected CpG content is ≥ 0.6, and (c) the general length of CGI is greater than 200 nucleotides...

AIM: To retrospectively evaluate the diagnostic performance of free-breathing diffusion-weighted imaging (FB-DWI) with modified imaging parameter settings for detecting hepatocellular carcinomas (HCCs). METHODS: Fifty-one patients at risk for HCC were scanned with both FB-DWI and respiratory-triggered DWI with the navigator echo respiratory-triggering technique (RT-DWI). Qualitatively, the sharpness of the liver contour, the image noise and the chemical shift artifacts on each DWI with b-values of 1000 s/mm(2) were independently evaluated by three radiologists using 4-point scoring...

Unified analysis of complex reactions of an activity-based probe with proteins in a proteome remains an unsolved challenge. We propose a power expression, rate = k(obs)[Probe](α), for scaling the progress of proteome-wide reactions and use the scaling factor (0 ≤ α ≤ 1) as an apparent, partial order with respect to the probe to measure the "enzyme-likeness" for a protein in reaction acceleration. Thus, α reports the intrinsic reactivity of the protein with the probe. When α = 0, the involved protein expedites the reaction to the maximal degree; when α = 1, the protein reacts with the probe via an unaccelerated, bimolecular reaction...

We present a case of an incidental diagnosis of panhypopituitarism in a 68-year-old African American man admitted to our psychiatric inpatient unit with symptoms suggestive of schizophrenia. The case was unusual as a first-episode psychosis given the patient's age. In the course of his admission, the patient's clinical condition deteriorated culminating in a sudden altered mental status which prompted a transfer to the medical floors and further investigations. A head CT scan and a pituitary MRI revealed a near total resection of the pituitary while laboratory investigations revealed hyponatremia and a grossly low hormone profile...

The negative emotional consequences associated with life stress exposure in an individual can affect the emotional state of social partners. In this study, we describe an experimental rat model of social stress contagion and its effects on social behaviour and cardiac autonomic and neuroendocrine functions. Adult male Wistar rats were pair-housed and one animal (designated as "demonstrator" (DEM)) was submitted to either social defeat stress (STR) by an aggressive male Wild-type rat in a separate room or just exposed to an unfamiliar empty cage (control condition, CTR), once a day for 4 consecutive days...
