Rendimento de grãos de híbridos de milho em duas densidades de plantas com e sem a retirada dos perfilhos Grain yield of maize hybrids at two plant densities with and without tillers removal

Ciência Rural, 2009
O milho não possui um mecanismo efetivo de compensação de espaços vazios na lavoura. Desse modo, híbridos perfilhadores podem ser mais eficientes no aproveitamento dos recursos ambientais, principalmente sob baixas populações de plantas.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Effects of plant population and nitrogen fertilizer on yield and efficiency of maize-bean intercropping. [PDF]

, 2014
Nitrogen supply and plant population are basic parameters for cereal-legume intercropping. In order to study plant population and nitrogen fertilizer effects on yield and yield efficiency of maizebean intercropping, a field experiment was established ...

Predictors of response and rational combinations for the novel MCL‐1 inhibitor MIK665 in acute myeloid leukemia

Molecular Oncology, EarlyView.
This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...

Regulation of Cydia pomonella in the Northern German climate [PDF]

, 2008
Population control of the codling moth (Cydia pomonella) is of great importance in ecological fruit-growing. In the work described here we attempted (1) to determine the efficacy of plant protection preparations certified for organic fruit production ...

Epidemics in Networks of Spatially Correlated Three-dimensional Root Branching Structures

, 2011
Using digitized images of the three-dimensional, branching structures for root systems of bean seedlings, together with analytical and numerical methods that map a common 'SIR' epidemiological model onto the bond percolation problem, we show how the ...

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Tumor and germline testing with next generation sequencing in epithelial ovarian cancer: a prospective paired comparison using an 18‐gene panel

Molecular Oncology, EarlyView.
Genetic testing in epithelial ovarian cancer includes both germline and tumor‐testing. This approach often duplicates resources. The current prospective study assessed the feasibility of tumor‐first multigene testing by comparing tumor tissue with germline testing of peripheral blood using an 18‐gene NGS panel in 106 patients.

Distribuição de sementes de milho e soja em função da velocidade e densidade de semeadura Distribution of corn and soybean seeds in function of the sowing speed and density

Ciência Rural, 2009
Com o objetivo de avaliar a distribuição de sementes de milho e soja por uma semeadora-adubadora de precisão em função da velocidade de trabalho e da densidade de sementes, foi conduzido um experimento em pista de areia conforme norma internacional.
