COVID-19 vaccination campaigns take shape

Covid-19 Vaccination and Reactivation of Varicella Zoster Virus

Introduction: After COVID-19 pandemic in 2020 that mostly affects upper respiratory tract, the scientists investigated an effective vaccine against the virus. As the vaccination of general population started some patients were visited with varicella zoster virus activation following the COVID vaccine.

Flower Petals Take Shape

Spring gardens will soon bloom with an abundance of flowering plants—from cultivated roses to hillside wildflowers. The diversity among flowering plants is remarkable, and even within a single plant, you find an assortment of shapes and sizes. Plant organs—leaves and petals, for instance—clearly have distinct forms and functions and are subject to different evolutionary pressures. Yet scientist...

Watching eyes take shape

Vertebrate eye formation is a multistep process requiring coordinated inductive interactions between neural and non-neural ectoderm and underlying mesendoderm. The induction and shaping of the eyes involves an elaborate cellular choreography characterized by precise changes in cell shape coupled with complex cellular and epithelial movements. Consequently, the forming eye is an excellent model ...

Neurons Take Shape

To construct the intricate network of connections that supports the functions of an adult nervous system, neurons must form highly elaborate processes, extending in the appropriate direction across long distances to form synapses with their partners. As the nervous system takes shape, the process of neuronal morphogenesis is controlled by a broad repertoire of cellular signals. These extracellu...
