Posterior reversible encephalopathy syndrome (PRES) is diagnosed based on neuroradiological findings. Typically, PRES is reversible and presents with a good outcome; however, fatal outcomes have been reported. We report an autopsied case showing PRES-like neuroradiological findings associated with premedication including tacrolimus for autologous peripheral blood stem cell transplantation in a 28-year-old woman with a 2-year history of acute myeloid sarcoma/acute myeloid leukemia. Neurological examination revealed disturbed consciousness, muscle weakness in all extremities, and bilaterally diminished tendon reflexes...

Opipramol was developed in the 1960s as an antidepressant and has chemical similarities with tricyclic antidepressants. Pharmacodynamic properties with absent reuptake inhibition of serotonin and noradrenaline and agonism at sigma receptors distinguish opipramol from tricyclics. Furthermore, antidepressive effects are smaller than the anxiolytic ones. The mechanism of action of opipramol is currently not sufficiently understood. Agonistic effects at sigma receptors have been linked with therapeutic effects...

OBJECTIVE: For a decade it has been known that the insular lobe epilepsy can mimic frontal lobe epilepsy. We aimed to clarify the pattern of functional coupling occurring during the frontal presentation. METHODS: We analyzed five insular lobe epilepsy patients. Frontal semiology was predominant for three of them, whereas insular semiology was predominant for the two others. We applied the non-linear regression analysis to stereoelectroencephalography-recorded seizures...

Acid treatment of clay minerals is known to modify their properties such as increase their surface area and surface acidity, making them suitable as catalysts in many chemical processes. However, the role of these surface properties during biodegradation processes of polycyclic aromatic hydrocarbons (PAHs) is only known for mild acid (0.5 M Hydrochloric acid) treated clays. Four different clay minerals were used for this study: a montmorillonite, a saponite, a palygorskite and a kaolinite. They were treated with 3 M hydrochloric acid to produce acid activated clay minerals...

With the intensification of human activities, fresh water resources are increasingly being exposed to contamination from effluent disposal to land. Thus, there is a greater need to identify the sources and pathways of water contamination to enable the development of better mitigation strategies. To track discharges of domestic effluent into soil and groundwater, 10 synthetic double-stranded DNA (dsDNA)(3) tracers were developed in this study. Laboratory column experiment and field groundwater and soil lysimeter studies were carried out spiking DNA with oxidation-pond domestic effluent...

#14
Brian S Biesman, Cara Costner
BACKGROUND AND OBJECTIVE: Laser-assisted treatment of tattoos is well recognized to produce opaque epidermal whitening that prevents multiple sequential passes during a single treatment session. The amount of epidermal whitening produced in association with the procedure can be minimized by topical application of perfluorodecalin (PFD), which is an optical clearing agent. This pivotal trial assessed the ability of a transparent PFD-infused patch used in conjunction with a Q-switched nanosecond laser in the treatment of tattoos to permit multiple laser passes during a single 5 minute treatment session in comparison to the number of passes that could be completed using conventional treatment of the tattoo with the laser alone...

AIMS: X-linked adrenoleukodystrophy (X-ALD) is a genetic white matter disorder in which demyelination occurs due to accumulation of very long chain fatty acids. Inflammation in the brain white matter is a hallmark of the pathology of cerebral X-ALD, but the underlying pathogenic mechanisms are still largely unknown. In other inflammatory demyelinating disorders such as multiple sclerosis, the expression of heat shock proteins (HSPs) in combination with interferon-γ (IFN-γ) has been suggested to play a prominent role in the initiation of demyelination and inflammation...

When individuals are highly committed to their romantic relationship, they are more likely to engage in pro-relationship maintenance mechanisms. The present research expanded on the notion that commitment redirects self-oriented goals to consider broader relational goals and examined whether commitment interacts with a promotion and prevention focus to activate derogation of attractive alternatives. Three studies used cross-sectional and experimental approaches. Study 1 showed that romantically involved individuals predominantly focused on promotion, but not prevention, reported less initial attraction to an attractive target than single individuals, especially when highly committed to their relationship...

Vascular plants rely on differences in osmotic pressure to export sugars from regions of synthesis (mature leaves) to sugar sinks (roots, fruits). In this process, known as Münch pressure flow, the loading of sugars from photosynthetic cells to the export conduit (the phloem) is crucial, as it sets the pressure head necessary to power long-distance transport. Whereas most herbaceous plants use active mechanisms to increase phloem sugar concentration above that of the photosynthetic cells, in most tree species, for which transport distances are largest, loading seems, counterintuitively, to occur by means of passive symplastic diffusion from the mesophyll to the phloem...

Antiestrogen-resistant and triple-negative breast tumors pose a serious clinical challenge because of limited treatment options. We assessed global gene expression changes in antiestrogen-sensitive compared with antiestrogen-resistant (two tamoxifen resistant and two fulvestrant resistant) MCF-7 breast cancer cell lines. The branched-chain amino acid transaminase 1 (BCAT1), which catalyzes the first step in the breakdown of branched-chain amino acids, was among the most upregulated transcripts in antiestrogen-resistant cells...

CTCF is a haploinsufficient tumour suppressor gene with diverse normal functions in genome structure and gene regulation. However the mechanism by which CTCF haploinsufficiency contributes to cancer development is not well understood. CTCF is frequently mutated in endometrial cancer. Here we show that most CTCF mutations effectively result in CTCF haploinsufficiency through nonsense-mediated decay of mutant transcripts, or loss-of-function missense mutation. Conversely, we identified a recurrent CTCF mutation K365T, which alters a DNA binding residue, and acts as a gain-of-function mutation enhancing cell survival...

INTRODUCTION: Radiation-free 3D post-operative sequential follow-up in craniosynostosis is hindered by the lack of consistent markers restricting evaluation to subjective comparison. However, using the computed cranial focal point (CCFP), it is possible to perform correct sequential image superposition and objective evaluation. We used this technique for mean volume and shape change evaluation of the head utilizing 3D photos after endoscopically assisted trigonocephaly surgery. METHODS: We performed a mean head shape and volume evaluation on age grouped 3D photos (n = 86) of children who underwent endoscopically assisted strip craniectomy with helmet therapy...
