Nitrogênio e enxofre nas características morfogênicas do capim-marandu em substituição ao capim-braquiária em degradação em solo com baixo teor de matéria orgânica Nitrogen and sulphur on morphogenic characteristics of marandu palisadegrass replacing signalgrass under degradation in a low organic matter soil

Revista Brasileira de Zootecnia, 2008
Foi conduzido um experimento em casa de vegetação objetivando avaliar as características morfogênicas da Brachiaria brizantha cv. Marandu, cultivada com doses combinadas de nitrogênio e de enxofre, em um solo (Neossolo Quartzarênico) coletado de uma ...

Studies on the Tillering Primordium and Tillering Bud in Rice seedlings : (7) Developmental process of the tillering primordium and tillering bud

Japanese Journal of Crop Science, 1958
1) This investigation was undertaken to determine the developmental process of the tillering primordium and tillering bud in rice seedlings. 2) Rice seedlings used in this study were nursed in sand culture from the sowing to the stages of the third foliage leaf, and after then in water culture. Harvested samples were fiked in mixtured fluid of Formalin,

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

Molecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...

PROG1 acts upstream of LAZY1 to regulate rice tiller angle as a repressor

Crop Journal, 2023
Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Studies on the tillering primordium and tillering bud in rice seedlings. : (1) The influence of water depth on the development of tillering primordium and tillering bud,

Japanese Journal of Crop Science, 1951
1. This experiment was made to determine of the influence of water depth upon the growth of tillering primordium and tillering bud of rice seedlings. 2. The degrees of water depth used were three, 0 cm (saturated condition in the soil) 3.0 cm and 5.0 cm. 3.
