Comparative study of some species of the genus Acer L. in the Hirkan flora using dendrochronological methods [PDF]
BIO Web of ConferencesRecently, due to global climate change and unregulated human economic activities, biodiversity has significantly degraded, which has led to changes and reductions in the ranges of species.

Frontiers in Plant Science, 2021 A bimodal radial growth (RG) pattern, i.e., growth peaks in spring and autumn, was repeatedly found in trees in the Mediterranean regions, where summer drought causes reduction or cessation of cambial activity. In a dry inner Alpine valley of the Eastern

The radial growth of univalent functions
Journal of Computational and Applied Mathematics, 2004 Let \(f(z)= z+ a_2z^2+\cdots\) be a function analytic and univalent in the unit disk, i.e. \(f\) belongs to the well-known class \(S\). Denote by \[ \underline\alpha(\theta)= \liminf_{r\to 1-}\,{\log| f(re^{i\theta}|\over \log(1/(1- r))} \] and \(I(f)= \{\theta\in [0, 2\pi): \underline\alpha(\theta)> 0\}\). It follows from a classical result of \textit{

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Snow Cover and Permafrost Soil Temperature Influence on the Radial Growth of Trees in Central Yakutia [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2012 Analysis of snow cover and permafrost soil temperature regime and their influence on the radial growth of trees in Central Yakutia were carried out. Snow depth and the period of its establishment in the previous year determines the intensity and rate of ...

In Vitro Effects of Leaf Extracts from Brassica rapa on the Growth of Two Entomopathogenic Fungi
Journal of Fungi, 2021 This study aimed to determine the inhibitive or stimulatory effects of leaf extracts from two Brassica rapa subspecies on the hyphal growth of two well-known entomopathogenic fungi, Cordyceps fumosorosea and Beauveria bassiana.

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...
