A Simple and User-Friendly Method for High-Quality Preparation of Pollen Grains for Scanning Electron Microscopy (SEM).

Pollen is becoming an increasingly important subject for molecular researchers in genetic engineering, plant breeding, and environmental monitoring. To broaden the scope of these studies, it is essential to develop accessible methods for scientists who are not specialized in palynology. The article presents a simplified technical procedure for preparing pollen grains for scanning electron microscopy (SEM).

Automating physical intuition in nonlinear fiber optics with unsupervised dominant balance search.

Identifying the underlying processes that locally dominate physical interactions is the key to understanding nonlinear dynamics. Machine-learning techniques have recently been shown to be highly promising in automating the search for dominant physics, adding important insights that complement analytical methods and empirical intuition. Here we apply a fully unsupervised approach to the search for dominant balance during nonlinear and dispersive propagation in an optical fiber and show that we can algorithmically identify dominant interactions in cases of optical wavebreaking, soliton fission, dispersive wave generation, and Raman soliton emergence.

Isolated Medial Platysmaplasty and Harmonization of the Lower Third of Face with Local Fat Autograft: A Case Report.

One of the most common complaints of patients seeking plastic surgery is the presence of age-related changes in the lower third of the face. These often include vertical platysmal bands, a double chin, Venus rings, the absence of the cervico-mental angle, hypertonicity of the muscles in the mental area, and insufficient projection of the chin. The development and implementation of less-traumatic methods of correction of the lower third of the face and harmonization of the projection of the cervico-mental region remain relevant.

Microsurgical Clip Reconstruction of a True Posterior Communicating Artery Aneurysm.

Approximately 25% of intracranial aneurysms originate at the internal carotid artery and posterior communicating artery (PCoA) junction. In contrast to typical PCoA aneurysms, which are usually saccular, a subset known as true PCoA aneurysms arise directly from the PCoA. These represent about 1.

CRISPR/Cas9-mediated мultiplexed multi-allelic mutagenesis of genes located on A, B and R subgenomes of hexaploid triticale.

The first-time generation of hexaploid triticale plants harbouring variable panels of novel mutations in gene families involved in starch biosynthesis has been achieved by the subgenome-independent multiplexed CRISPR/Cas9-mediated editing.
