The Nucleus SUMMARY OF KEY POINTS Nuclear Envelope. Cytoplasm is separated from nucleoplasm by the nuclear envelope, a double set of membranes with a narrow perinuclear space; the outer membrane binds ribosomes and is continuous with the RER.
Hace 5 días · The nucleus is the positively charged centre of an atom and contains most of its mass. It is composed of protons, which have a positive charge, and neutrons, which have no charge. Protons, neutrons, and the electrons surrounding them are long-lived particles present in all ordinary, naturally occurring atoms.
Hace 2 días · Viral interactions with the nucleus, volume II. Viruses are infective agents involved in a plethora of pathologies, ranging from the common cold such as Rhinovirus, to lethal diseases, such as Ebola. In recent times, the world has weathered crises caused by SARS-CoV-2 that killed millions of people worldwide.
Hace 4 días · Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
Hace 3 días · The comparative histological analyses have revealed the specialized functions of ligular adaxial sclerenchyma cells in regulating leaf angle by providing mechanical strength and limiting cell elongation. Additionally, we generated a comprehensive transcriptomic atlas of the ligular region and validated the positive role of bHLH30 and its homolog, bHLH155, in the expansion of leaf angle in maize.
Hace 1 día · Objective. The progression of impulsive-compulsive behaviors (ICB) in Parkinson's Disease (PD) following subthalamic deep brain stimulation (DBS) surgery displays a large inter-patient variability. However, the link between the subthalamic neural activity at the single-neuron level and the postoperative evolution of ICB remains unclear. In this study, we investigated neural features associated ...
Hace 1 día · The properties of an atomic nucleus depend on both atomic and neutron numbers. With their positive charge, the protons within the nucleus are repelled by the long-range electromagnetic force, but the much stronger, but short-range, nuclear force binds the nucleons closely together.
