Psychosis Assessment in Early-Stage Parkinson's Disease: Comparing Parkinson's Psychosis Questionnaire with the Brief Psychiatric Rating Scale in a Portuguese Sample
Psychotic symptoms in Parkinson's disease (PD) are frequent, disabling, and an important prognostic factor. Thus, screening instruments for detecting psychosis in PD are needed. For this purpose, we applied the Parkinson's Psychosis Questionnaire (PPQ), a short structured questionnaire, which requires no specific training, along with the Brief Psychiatric Rating Scale, expanded version (BPRS-E), for rating general psychopathology, including psychotic symptoms.
We evaluated, in a cross-sectional study, a Portuguese sample of 36 early-stage PD patients (mean age of 73 years; mean duration of illness of 3.2 years). The PPQ total score correlated with the BPRS-E total score (0.359; P = 0.032) and with the BPRS-E-positive symptoms score (0.469; P = 0.004). The prevalence of psychosis (41.7%) was higher than expected. Sampling bias and detection of minor psychotic phenomena may have contributed to this result.
These findings suggest that the PPQ should be further evaluated as a feasible assessment for psychotic symptoms in PD
Alternativas ao processo tradicionalmente utilizado na provĂncia de nampula (Moçambique) para a produção de suco de caju.
Neste documento, descrevem-se dois processos para o aproveitamento do pedĂșnculo de caju: produção de suco parcialmente clarificado, com teor baixo de polpa, e suco de caju clarificado, isento de polpa, adaptados das condiçÔes tradicionais de produção da cajuĂna brasileira para a realidade moçambicana, e que permite obter um produto com boas caracterĂsticas sensoriais e estabilidade de aproximadamente 60 dias estocados em temperatura ambiente.bitstream/item/55351/1/COT11019.pd
The Large Quasar Reference Frame (LQRF) - an optical representation of the ICRS
The large number and all-sky distribution of quasars from different surveys,
along with their presence in large, deep astrometric catalogs,enables the
building of an optical materialization of the ICRS following its defining
principles. Namely: that it is kinematically non-rotating with respect to the
ensemble of distant extragalactic objects; aligned with the mean equator and
dynamical equinox of J2000; and realized by a list of adopted coordinates of
extragalatic sources. Starting from the updated and presumably complete LQAC
list of QSOs, the initial optical positions of those quasars are found in the
USNO B1.0 and GSC2.3 catalogs, and from the SDSS DR5. The initial positions are
next placed onto UCAC2-based reference frames, following by an alignment with
the ICRF, to which were added the most precise sources from the VLBA calibrator
list and the VLA calibrator list - when reliable optical counterparts exist.
Finally, the LQRF axes are inspected through spherical harmonics, contemplating
to define right ascension, declination and magnitude terms. The LQRF contains
J2000 referred equatorial coordinates for 100,165 quasars, well represented
across the sky, from -83.5 to +88.5 degrees in declination, and with 10 arcmin
being the average distance between adjacent elements. The global alignment with
the ICRF is 1.5 mas, and the individual position accuracies are represented by
a Poisson distribution that peaks at 139 mas in right ascension and 130 mas in
declination. It is complemented by redshift and photometry information from the
LQAC. The LQRF is designed to be an astrometric frame, but it is also the basis
for the GAIA mission initial quasars' list, and can be used as a test bench for
quasars' space distribution and luminosity function studies.Comment: 23 pages, 23 figures, 6 tables Accepted for publication by Astronomy

Sistema de produção de milho safrinha de alta produtividade: safras 2008 e 2009.
bitstream/item/47392/1/circ-160.pd
Caracterização do cultivo de milho safrinha de alta produtividade em 2008 e 2009.
O termo milho safrinha Ă© empregado para o cultivo de milho de sequeiro semeado de janeiro a abril, apĂłs a colheita da cultura de verĂŁo. Para caracterizar os sistemas de produção de altas produtividades de milho safrinha foram coletados dados referentes a 1.138 lavouras que obtiveram produtividade acima de 5.000 kg ha-1, nos estados da regiĂŁo Centro-Oeste, em SĂŁo Paulo e no ParanĂĄ. Embora tenham sido constatados rendimentos superiores a 8.000 kg ha-1 em todos os estados produtores de milho safrinha, a maior frequencia Ă© de lavouras com rendimentos entre 5.000 e 7.000 kg ha-1. Nessas lavouras, predominou o plantio de hĂbridos simples e de ciclo precoce, no sistema plantio direto, com o milho sendo implantado no mĂȘs de fevereiro e cultivado geralmente apĂłs a soja. Em SĂŁo Paulo e no ParanĂĄ, predominam o uso do espaçamento convencional, enquanto que nos estados da regiĂŁo Centro-Oeste a utilização de espaçamento reduzido Ă© maior, especialmente em GoiĂĄs. A população de plantas variou de 45 a 65 mil plantas por hectare, com maior frequĂȘncia no uso de 50 a 55 mil plantas por hectare. Cerca de 90% das lavouras receberam tratamento quĂmico com fungicidas para o controle de doenças. O nĂșmero de aplicaçÔes de inseticidas variou de zero atĂ© quatro aplicaçÔes, sendo mais frequente duas e trĂȘs aplicaçÔes
