Epilepsy is a chronic disorder with reoccurrence of unprovoked seizures that happens because of the electrical events that occur in the brain. An epileptic seiszure is a central nervous system disorder that affects neuron activity by causing an excessive amount of activity in the brain. This can be attributed to a large amount of action potentials that don’t allow for any relief, which can cause damage to the cell. Antiepileptic drug therapy for epilepsy even though proven to give relief to…

Noroviruses (NoV) are important human pathogens and a major public health threat. Noroviruses are non-enveloped, single-stranded, positive sense RNA viruses that cause acute gastroenteritis in humans (1-4). Noroviruses have been referred to as ‘cruise ship viruses’ from well-publicized cruise ship outbreaks although these outbreaks account for less than 1% of all outbreaks worldwide (5). The symptoms and illness associated with Norovirus infections is often referred to as ‘stomach flu’, despite…

and the release of NFkB which enter the nucleus. NFkB is a transcription factor that is normally found in cytoplasm. IkB activates transcription of genes for inflammatory cytokines, which are synthesized in the cytoplasm and secreted through the endoplasmic…

Lipids, or fats, are processed and consumed in the small digestive tract. We will figure out how bile salts emulsify fat so pancreatic lipase can process it. We will likewise figure out how fats first enter lymphatic vessels, called lacteals, before entering your blood course. Nourishments, for example, meats, dairy items, seeds, nuts, and oils, contain dietary fat. Fat is a typical illustration of a lipid, and in this lesson you will find out about the one of a kind way lipids, for example,…

proteins into the nucleus occurs via a channel called nuclear pore complex (NPC), which penetrates and spans the nuclear envelope, a double membrane that separates the nucleus from the cytoplasm. The outer nuclear membrane is continuous with the endoplasmic reticulum, hence giving a shorter pathway for proteins to enter the nucleus; inner nuclear membrane contains proteins acting as binding site for nuclear lamina, indirectly providing support for the NPC as the primary function of nuclear…

power decrease can be out of order downward into four separate stage, these be; 1. Muscle commencement: The coast nerve stimulates an act potential (impulse) to pass downward a neuron to the neuromuscular connection. This stimulate the sarcoplasmic reticulum to let go calcium into the power…

1 mm to 1 m, and each axon synapses with 1 000 to over 10 000 neurons. Every axon’s cytoplasm (or axoplasm) contains neurofibrils, neurotubules, small vesicles, lysosomes, and mitochondria. It cannot create proteins because it has no rough endoplasmic reticulum. A plasma axolemma (cell membrane) surrounds the entire axon to protect it. In a multipolar neuron, the axons’s base is attached to the soma at a thickened cone-shaped region called the axon hillock. Nerve impulses occur between the…

The purpose of this EEI is to create and analyse an experiment that relates to and supports the theory of osmosis in biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference…

as a result of using ultrasound leads to the destruction of the integrity of muscle cells and sub-cellular components, such as the endoplasmic reticulum, increase the rate and efficiency of enzymatic reactions in beef and lamb muscle; and also cause a selective heating effect on collagen .One study states that sonication of beef muscle with an intensity of 2 W/ cm2 for 2 h at a frequency of…
