Dramatic recovery after IV thrombolysis in anterior circulation ischemic stroke...

BACKGROUND AND PURPOSE: Dramatic recovery (DR) after thrombolysis is dependent of vessel recanalization and is predictive of favorable clinical outcome. Successful recanalization is not equivalent to DR. Our objective was to assess its frequency and evaluate clinical and biochemical predictors and their prognosis. METHODS: We analyzed prospectively registered data from January 2007 to September 2012. All patie...

Dynamic myelopathy in Hirayama disease

Pyrazole synthesis under microwave irradiation and solvent-free conditions

This paper presents a study of solvent-free reaction conditions using microwave irradiation (MW) to obtain 4,5-dihydro-1H-pyrazoles and dehydrated pyrazoles by the cyclocondensation reaction of 4-alkoxy-1,1,1-trifluoro-3-alken-2-ones [CF3C(O)CH=C(R¹)OR, where R/R¹ = Et/H, Me/Me and Me/Ph] with hydrazines [NH2NH-R², where R² = CO2Me, Ph, CH2CH2OH]. Some reactions were performed under the same reaction conditions...

Effect of postarvest elicitors on ‘fuyu’ persimmon quality during cold storage

Proceedings of the International Conference “Environmentally friendly and safe technologies for quality of fruit and vegetables”, held in Universidade do Algarve, Faro, Portugal, on January 14-16, 2009. This Conference was a join activity with COST Action 924. ; To induce resveratrol synthesis and reduce skin browning in ‘Fuyu’ persimmons, fruit were treated directly after harvest with the following elicitors:...

Caracterização farmacognóstica das folhas e sementes de Albizia lebbeck (L.) Be...

Albizia lebbeck (L.) Benth. é popularmente conhecida no Brasil por coração-de-negro. É uma espécie aclimatada nesse país. As sementes dessa espécie são utilizadas no tratamento de diarréia, disenteria e hemorróidas e as folhas, no tratamento de úlceras e nas conjuntivites alérgicas. Este trabalho foi realizado com a finalidade de determinar as características macroscópicas e microscópicas das folhas e sementes ...

Simultaneous supratentorial and brainstem abscesses due to Listeria monocytogenes.

Multiple supratentorial abscesses caused by Listeria monocytogenes are rare. We report the simultaneous occurrence of multiple supratentorial and brainstem abscesses due to Listeria, in a patient under corticotherapy for an exacerbation of ulcerative colitis. MR imaging features before and after successful conservative treatments are depicted. In immunocompromised patients with supratentorial listerial abscesse...

A solvent-free synthesis of beta-enamino trihalomethyl ketones

An efficient green procedure to prepare a series of twenty-six 4-amino-1,1,1-trihalo-3-alken-2-ones [CX3C(O)CH=C(R¹)NR² R³, where X = F, Cl, R¹ = H, Me, and R²/R³ = H/Ph, H/4-F-Ph, H/Bn, H/(CH2)2OH, Me/Ph, Me/Bu, Et/Et, -(CH2)4-] from the solvent-free reaction of 1,1,1-trihalo-4-alkoxy-3-alken-2-ones with primary and secondary amines at room temperature for five minutes is reported (yields of 73-99%).
