Sense of space: Tactile sense for exploratory behavior of roots
In soil, plant roots grow in heterogeneous environments. Plant roots are always facing the difficulty of searching effectively the patchy natural resources, such as water, oxygen, ions and mineral nutrition.

Personalized Zebrafish Models for Fusion‐Positive Pediatric Sarcomas
ABSTRACT Clinical sequencing efforts have revolutionized our approaches to categorizing pediatric cancers in real time. This has dramatically improved our ability to profile pediatric tumors, identify actionable vulnerabilities, and influence clinical care.

Root Tropisms: New Insights Leading the Growth Direction of the Hidden Half
Tropisms are essential responses of plants, orienting growth according to a wide range of stimuli. Recently, considerable attention has been paid to root tropisms, not only to improve cultivation systems, such as those developed for plant-based life ...

Weight Spaces and Root Spaces of Kac-Moody Algebras
Let \({\mathfrak g} (A)\) be the Kac-Moody algebra associated to a symmetric generalized Cartan matrix. The purpose of the paper under review is to give an explicit realization of the weight spaces of an integrable highest weight \({\mathfrak g} (A)\)-module \(L(\lambda)\) and the weight spaces of the universal enveloping algebra \(U({\mathfrak n}_ -)\)

Powers of roots in linear spaces
Let \(K\) be a number field, \(n>0\) be a positive integer. Let \(\alpha\) be an algebraic number such that \(\alpha^n=:\kappa\) belongs to \(K\) and no power of \(\alpha\) with smaller positive exponent lies in \(K\). The authors are interested in linear relations over \(K\) among the powers \(\alpha^j\) with \(0\leq ...

Insertion of Continuous Real Functions on Spaces, Bispaces, Ordered Spaces and Pointfree Spaces—A Common Root [PDF]
A biframe is a triple consisting of a frame (called the total part of the biframe) and two subframes which together generate the total part. In the same way that a frame has its co-frame of sublocales which can be made into a frame by reverse inclusion, a biframe also has what could informally be called a ``biframe of sublocales''. For a given biframe,

ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Effects of Simulated Space Radiations on the Tomato Root Proteome
Plant cultivation on spacecraft or planetary outposts is a promising and actual perspective both for food and bioactive molecules production. To this aim, plant response to ionizing radiations, as an important component of space radiation, must be ...
