Hypoperfusion injury related to blood pressure decrease in acute hypertensive intracerebral hemorrhage continues to be a controversial topic. Aggressive treatment is provided with the intent to stop the ongoing bleeding. However, there may be additional factors, including autoregulation and increased intracranial pressure, that may limit this approach. We present here a case of acute hypertensive intracerebral hemorrhage, in which aggressive blood pressure management to levels within the normal range led to global cerebral ischemia within multiple border zones. Global cerebral ischemia may be of concern in the management of hypertensive hemorrhage in the presence of premorbid poorly controlled blood pressure and increased intracranial pressure.

Objective: We describe a patient diagnosed with acute neuroborreliosis presenting with anterior optic neuritis (papillitis) in a non-endemic region. Case Presentation: A 43-year-old previously healthy right handed man admitted due to an insidious onset of severe headache and spells of ascending paresthesias from his right foot into his right arm and face followed by speech arrest and clumsiness of his right hand. His neurologic exam was significant for somnolence, nuchal rigidity and Kernig and Brudzinski signs were present. MRI of the brain with gadolinium showed diffuse hyperintense signal involving the supra and infratentorial cortical sulci, with associated faint diffuse leptomeningeal enhancement, consistent most likely with diffuse leptomeningoencephalitis. EEG: normal. CSF VDRL was negative. Dilated fundus exam revealed mild optic nerve edema more significant to the left than to the right eye, confirmed and measured by spectral domain OCT (Optical Coherence Tomography). There was an evidence of posterior uveitis with an early vitreous hemorrhage superficial to the left optic nerve. Lyme disease serum antibody (IgM) Immunoblotting was positive in 2 bands confirming the diagnosis of neuroborreliosis. Conclusion: Optic nerve involvement in Lyme disease is an uncommon complication that should be confirmed by specific diagnostic criteria to establish its causal relation.

In this work,we studied the adsorption of modified cellulose nanocrystals onto solid surfaces by quartz crystal microbalance with dissipation monitoring(QCM-D).Cellulose nanocrystals obtained from tunicate(CNC)were modified at reducing end by amidation *** different functionalities were investigated:a polyamine dendrimer(CNC-NH_(2)),which interacts with gold surface by the amine groups;and a biotin moiety(CNC-Biot),which has a strong affinity for the protein streptavidin(SAV).QCM-D results revealed different adsorption behaviors between modified and unmodified ***,unmodified CNCs covered almost all the surface forming a rigid and flat layer whereas reducing end modified CNCs remained rather upright forming a hydrated and viscoelastic layer with lower surface *** analysis of adsorption kinetics allowed the calculation of an apparent collision rate factor,which resulted 10-fold higher for unmodified CNCs compared to reducing end modified CNCs,therefore,demonstrating the different adsorption behavior.

This work aims at characterizing organic matter produced by an alga Euglena gracil~ and a cyanobacteria Microcystis aeruginosa and assessing the evolution of its characteristics during growth. A culture medium was optimized. The species growth phases were monitored using both visible spectrophotometry and flow cytometry cell counting. Organic matter fractionation according to hydrophobicity and specific UV absorbance （SUVA） index were used to specifically characterize the produced algal organic matter （AOM）. The AOM characteristics were both growth phase and species dependent. However, a similar evolution was observed. The hydrophilic fraction （HPI） was the major fraction whatever the growth phases and was almost the only one produced during lag and exponential phases. It represented around 75% of AOM during exponential phase and then decreased when the stationary phase appeared. It represented 46% and 60% of the AOM during late decline phase for the cyanobacteria and the alga respectively. The hydrophobic （HPO） and transphilic （TPH） fractions started to appear from the beginning of the stationary phase with more hydrophobic compounds coming from intracellular organic material of dying cells. HPO and TPH percentages still increased during the decline phase probably because of two additional processes： photo-dissolution and leaching of particulate organic matter from cells fragments. A comparison of AOM during late decline phase and natural organic matter （NOM） from Glane River （France） underlined that AOM was more fiydrophilic and presented a lower SUVA for each fractions than NOM. However, the difference between NOM and AOM hydrophobicity narrowed during decline phase.
