Motivational Interviewing to Increase Physical Activity Behavior in Cancer Patients: A Pilot Randomized Controlled Trials
OBJECTIVE:
This pilot randomized controlled trial (RCT) aimed at evaluating the feasibility and potential efficacy of a motivational interviewing (MI) intervention to increase physical activity (PA) behavior in cancer patients.
METHODS:
Participants were randomly assigned to an experimental group with standard care plus 12 MI sessions within 12 weeks or a control group with standard care only. The number of recruited participants and the modality of recruitment were recorded to describe the reach of the study. The acceptability of the study was estimated using the attrition rate during the intervention phase. The potential efficacy of the intervention was evaluated by analyzing the PA behavior.
RESULTS:
Twenty-five participants were recruited within the 16-month recruitment period (1.6 participants per month). Five participants (38.5%) from the experimental group (n = 13) and one participant (8.3%) from the control group (n = 12) dropped out of the study before the end of the intervention phase. No group by time interaction effect for PA behavior was observed at the end of the intervention.
CONCLUSION:
Due to the low recruitment rate and compliance, no conclusion can be drawn regarding the efficacy of MI to increase PA behavior in cancer patients. Moreover, the current literature cannot provide any evidence on the effectiveness of MI to increase PA in cancer survivors. Future RCTs should consider that the percentage of uninterested patients to join the study may be as high as 60%. Overrecruitment (30% to 40%) is also recommended to accommodate the elevated attrition rate
Velocidade de embebição de sementes de soja submetidas a diferentes recobrimentos.
O tratamento de sementes de soja é uma prática utilizada para aumentar o desempenho das sementes, especialmente durante as fases iniciais do ciclo. A utilização do tratamento de sementes com polímeros tem sido uma alternativa para os agricultores por permitir melhor fi xação dos princípios ativos utilizados no tratamento químico. Entretanto, esses produtos não devem afetar as propriedades fisiológicas e físicas das sementes, como a velocidade de embebição. Assim, o objetivo do trabalho foi estudar o efeito de diferentes recobrimentos na velocidade de embebição das sementes de soja. Foram utilizados dois lotes de sementes de soja das cultivares SYN1263 RR e BMX Potência RR, as quais foram submetidas a seis diferentes recobrimentos: 1: Testemunha (ausência de fungicida, inseticida e polímero); 2: Fungicida + Inseticida; 3: Fungicida + Inseticida + Polímero A; 4: Fungicida + Inseticida + Polímero B; 5: Polímero A; 6: Polímero B. O fungicida e o inseticida utilizados foram Derosal Plus (carbendazim + thiram) e Cropstar FloRite 1197 (Nitral Urbana (imidacloprido + tiodicarbe), respectivamente, e os polímeros ) (A) e Laborsan (Laborsan) (B). Para a determinação da velocidade de embebição, as sementes foram dispostas sobre papel germitest umedecido 2,25 vezes o peso do papel seco e incubadas àtemperatura de 20°C, mensurando-se a massa das sementes em intervalos regularesde 1h, durante um período de 24h. De acordo com os resultados, o recobrimento das sementes de soja com os polímeros FloRite1197 (Nitral Urbana) e Laborsan (Laborsan) isolados ou em associação com o fungicida e inseticida não retardam a velocidade de absorção de água

The structure of Chariklo's rings from stellar occultations
Two narrow and dense rings (called C1R and C2R) were discovered around the
Centaur object (10199) Chariklo during a stellar occultation observed on 2013
June 3. Following this discovery, we planned observations of several
occultations by Chariklo's system in order to better characterize the physical
properties of the ring and main body. Here, we use 12 successful occulations by
Chariklo observed between 2014 and 2016. They provide ring profiles (physical
width, opacity, edge structure) and constraints on the radii and pole position.
Our new observations are currently consistent with the circular ring solution
and pole position, to within the km formal uncertainty for the ring
radii derived by Braga-Ribas et al. The six resolved C1R profiles reveal
significant width variations from to 7.5 km. The width of the fainter
ring C2R is less constrained, and may vary between 0.1 and 1 km. The inner and
outer edges of C1R are consistent with infinitely sharp boundaries, with
typical upper limits of one kilometer for the transition zone between the ring
and empty space. No constraint on the sharpness of C2R's edges is available. A
1 upper limit of m is derived for the equivalent width of
narrow (physical width <4 km) rings up to distances of 12,000 km, counted in
the ring plane
Second harmonic generation in SiC polytypes
LMTO calculations are presented for the frequency dependent second harmonic
generation (SHG) in the polytypes 2H, 4H, 6H, 15R and 3C of SiC. All
independent tensor components are calculated. The spectral features and the
ratios of the 333 to 311 tensorial components are studied as a function of the
degree of hexagonality. The relationship to the linear optical response and the
underlying band structure are investigated. SHG is suggested to be a sensitive
tool for investigating the near band edge interband excitations.Comment: 12 pages, 10 figure

Observation of Pulsed Gamma-rays Above 25 GeV from the Crab Pulsar with MAGIC
One fundamental question about pulsars concerns the mechanism of their pulsed
electromagnetic emission. Measuring the high-end region of a pulsar's spectrum
would shed light on this question. By developing a new electronic trigger, we
lowered the threshold of the Major Atmospheric gamma-ray Imaging Cherenkov
(MAGIC) telescope to 25 GeV. In this configuration, we detected pulsed
gamma-rays from the Crab pulsar that were greater than 25 GeV, revealing a
relatively high cutoff energy in the phase-averaged spectrum. This indicates
that the emission occurs far out in the magnetosphere, hence excluding the
polar-cap scenario as a possible explanation of our measurement. The high
cutoff energy also challenges the slot-gap scenario.Comment: Slight modification of the analysis: Fitting a more general function
to the combined data set of COMPTEL, EGRET and MAGIC. Final result and
conclusion is unchange
