In June 2017 we celebrate the 90th anniversary of the pioneer discovery of cerebral angiography, the seminal imaging technique used for visualizing cerebral blood vessels and vascular alterations as well as other intracranial disorders. Egas Moniz (1874-1955) was the...

Exogenous control over intracellular acidification: Enhancement via proton caged compounds coupled to gold nanoparticles and an alternative pathway with DMSO.

Data in brief

Carbone M, Sabbatella G, Antonaroli S, Remita H, Orlando V, Biagioni S, Nucara A.
PMID: 26870760
Data Brief. 2016 Jan 21;6:745-9. doi: 10.1016/j.dib.2015.12.032. eCollection 2016 Mar.

Proton caged compounds exhibit a characteristic behavior when directly dosed into cells or being coupled to gold nanoparticles prior to the dosing. When irradiated in the near ultraviolet region, they release protons that interact with intracellular HCO3 (-) to...

Int J Dev Neurosci. 1985;3(4):331-40. doi: 10.1016/0736-5748(85)90066-8.

Murine muscular dystrophy is characterized by a reduction of the 10S molecular form of acetylcholinesterase (AChE); this reduction occurs in both strains of dystrophic mice and at the time of the phenotypic appearance of the disease. In the present...

Environ Monit Assess. 1995 Jan;34(1):59-72. doi: 10.1007/BF00546246.

An innovative miniaturized kit based on the use of 2-week-old ozone-supersensitive tobacco germlings (Nicotiana tabacum L. cv. Bel-W3) raised in tissue culture plates was utilized, in conjunction with four calibrated automatic analyzers, to monitor the distribution of phytotoxic ground...

Compartment-dependent mitochondrial alterations in experimental ALS, the effects of mitophagy and mitochondriogenesis.

Frontiers in cellular neuroscience

Front Cell Neurosci. 2015 Nov 06;9:434. doi: 10.3389/fncel.2015.00434. eCollection 2015.

Amyotrophic lateral sclerosis (ALS) is characterized by massive loss of motor neurons. Data from ALS patients and experimental models indicate that mitochondria are severely damaged within dying or spared motor neurons. Nonetheless, recent data indicate that mitochondrial preservation, although...

Method for generating solitons sustained by competing nonlinearities by use of optical rectification.

Optics letters

Torres JP, Palacios SL, Torner L, Crasovan LC, Mihalache D, Biaggio I.
PMID: 18026524
Opt Lett. 2002 Sep 15;27(18):1631-3. doi: 10.1364/ol.27.001631.

We put forward a method for generating engineerable competing quadratic and cubic nonlinearities in suitable settings in which frequency generation is accompanied by optical rectification. The novel scheme is based on the full exploitation of the geometrical conditions that...

BACKGROUND: Down's syndrome (DS) is characterized by several immunological defects, especially regarding T cell compartment. DS is considered the best example of accelerated ageing in humans. Direct observations of the thymus have shown that in DS this organ undergoes...

Property tuning in charge-transfer chromophores by systematic modulation of the spacer between donor and acceptor.

Chemistry (Weinheim an der Bergstrasse, Germany)

Bures F, Schweizer WB, May JC, Boudon C, Gisselbrecht JP, Gross M, Biaggio I, Diederich F.
