Lymphocyte Depletion Rate as a Biomarker of Radiation Dose to Circulating Lymphocytes During Fractionated Partial-Body Radiation Therapy [PDF]
, 2022 PURPOSE: Radiation causes exponential depletion of circulating lymphocyte populations; in turn, radiation-induced lymphopenia is associated with worse survival for many solid tumors, possibly owing to attenuated antitumor immune responses.

"Adaptive response" - some underlying mechanisms and open questions [PDF]
, 2008 Organisms are affected by different DNA damaging agents naturally present in the environment or released as a result of human activity. Many defense mechanisms have evolved in organisms to minimize genotoxic damage. One of them is induced radioresistance

Molecular Adaptation during a Rapid Adaptive Radiation [PDF]
Molecular Biology and Evolution, 2013 "Explosive" adaptive radiations on islands remain one of the most puzzling evolutionary phenomena and the evolutionary genetic processes behind such radiations remain unclear. Rapid morphological and ecological evolution during island radiations suggests that many genes may be under fairly strong selection, although this remains untested.

, 2021 An adaptive response results in a reduced effect of a high challenging dose of a stressor after a smaller, inducing dose has been applied a few hours earlier. Radiation-induced fibrosarcoma (RIF) cells did not show an adaptive response, i.e.

Reed bamboos drive skull shape evolution in bush frogs of the Western Ghats, Peninsular India
Ecology and Evolution, 2023 Reed bamboo is a major ecological and economic resource for many animals, including humans. Nonetheless, the influence of this plant's evolutionary role on the morphology of animal species remains unexplored.

Polygenic adaptation from standing genetic variation allows rapid ecotype formation
eLife, 2023 Adaptive ecotype formation can be the first step to speciation, but the genetic underpinnings of this process are poorly understood. Marine midges of the genus Clunio (Diptera) have recolonized Northern European shore areas after the last glaciation.

Disincentives of organizational routines transfer
Annals of Business Administrative Science, 2019 In the case of sales and marketing organization reform discussed in this paper, organizational routines with excellent results were created. Despite visibility and standardization in a form usable for other organizations, the routines were not ...

A Novel Body Plan Alters Diversification of Body Shape and Genitalia in Live-Bearing Fish
Frontiers in Ecology and Evolution, 2021 Major evolutionary innovations can greatly influence subsequent evolution. While many major transitions occurred in the deep past, male live-bearing fishes (family Poeciliidae) more recently evolved a novel body plan.
