Abstract

Given that the relationship between music education and mathematics education has been speculated for a long time, the study seeks to investigate whether music education has effect on mathematics education or not. It is perceived that children who learn mathematics through music and dance tend to be more active, and would retain the same information well even by verbal instructions. Using a controlled randomized experiment, the study will involve 6th grade school going children from one city. Before the tests are administered in the factors, as music and mathematics, letters seeking permissions from parents will be sent. The letters ...

Homeostasis refers to any self-regulating process by which biological systems attempt to maintain stability despite changes in the external and internal environment (Sturmberg & Martin, 2013). Biological systems interact with each other to maintain a suitable condition of the internal environment for the survival of the living organism. The biological systems of the living organism are in a state of constant change. The regulation of the systems within a given range of various conditions helps to keep the living organisms alive and healthy. The systems also interact with the external environment in different ways. The conditions of the external environment ...

Introduction

The treatment for multitudes of diseases and disorders resulting from genetic reasons have been ambiguous since long as the only cure could be the correction of genes and DNA in the specific region. Gene therapy gave a promising horizon to the correction of such genetic defects whereby molecular tools are applied to reverse the mutation or any other changes in the DNA. The advancing biomedical research have offered several tools for gene therapy since last few decades that have been able to perform the desired roles but with one or the other limitations. Lately, CRISPR-Cas9 based tools for gene ...

Introduction

The body is on an ongoing and continuous quest to maintain an environment characterized with equilibrium. Scientifically, this state is called homeostasis. It is the body’s internal mechanism that is meant to make the person survive, despite the numerous internal and external changes it may encounter. The body of a person who was acutely exposed to a colder than usual environment would, for example, react by preserving the heat that is currently stored in and generated by the body—something which can be done in a lot of ways such as, but may not be limited to vasoconstriction, ...

Immunogenic cell death: the role of SAGE

Immunogenic cell death: the role of SAGE

Introduction

Millions of cells are always being removed in the human body not only to regulate and coordinate the body’s biochemical pathways but also to keep the cells healthy. This particular systematic removal of cells occurs through a selective mechanism called cell death or apoptosis process. Apoptosis is not a new concept in the understanding of the biological workings of the body. This homeostatic death of body cells has been defined as a tolerogenic or a non-immunogenic event for many [1]. However, new discoveries have unearthed the existence of a different concept ...

Immunogenic Cell Death: The Role of RAGE

Introduction Millions of cells are always being removed in the human bodyin order to regulate biological pathways and keep cells healthy through a particular mechanism called cell death or apoptosis. Through apoptosis, such homeostatic death of cells has been defined as a tolerogenic or a non-immunogenic event for many years [1]. However, during the past few years, scientists have discovered the occurrence of a different concept of cell death – immunogenic cell death (ICD), where the death of a cell stimulates a response from the immune system against antigens of a dead cell, and this mechanism of cell death may ...

Introduction

Daily activities performed by human beings is a certain way call for the use of force and energy in executing them. This energy is got from well feeding to ensure that the body muscles, joints, and bones stand up to the necessary task of undertaking a specific activity without much strain or getting tired without completion of the work or activity. Due to this, one must ensure that the body as a whole is fit to undergo the strain brought by the practise exercise to develop the muscles, bone, joints, and the body as a whole.

Principle of specificity is on of the ...

Re-uptake involves the reabsorption of neurotransmitters by any of the neurotransmitter receptors or transporters. The transporters involved are usually of pre-synaptic neurons. Re-uptake occurs after the neurotransmitter has transmitted a neural impulse. Re-uptake is very crucial in order for the normal functioning of synapses to take place. This is because it allows the neurotransmitters to be recycled, thereby regulating their levels in the synapse. This in turn dictates the length of time it takes for a signal - generated by neurotransmitter release - to last. Neurotransmitters are usually large hydrophilic molecules that cannot pass through the neuronal membranes. For this reason, ...

The Central Nervous System is the control system of the human body; it is the core of the human nervous system. The Central Nervous system is made up of the spinal cord and the brain. The brain uses the electrical signal, which is generated by the Central Nervous System. These electrical signals travel via the Peripheral Nervous System effector cells. These effector cells carry out physiological responses whenever the brain demands it. Axonal regeneration occurs successfully in the Peripheral Nervous System. However, regenerative axonal growth starts occurring in the Central Nervous System too, but stops two weeks after the ...

The regeneration of nerves throughout the human body has been a subject of much interest in biology recently. The unique characteristics of both the central nervous system (CNS) and the peripheral nervous system (PNS) provide insights into the mechanisms occurring after once damage occurs. A good understanding of tThe differences between these mechanisms also may lead to new therapies for nerve-damaged patients, including stroke patients. Following injury, the nerves in the CNS of an adult mammal will not regenerate, while the PNS will. These differences appear in every stage of axon regeneration. Within hours of axotomy, the PNS begins ...

Abstract

Bones are formed through a process known as osteogenesis from three different lineages. This process takes place through two different methods, which are intramembranous ossification and endochondral ossification. A large increment in bone mass takes place in childhood, as well as puberty, through the formation of endochondral bone. At this point, growth hormones are known to play a role. This paper will focus on the process of cartilage and bone formation and the stimulation of bone formation by the growth hormone. There are a number of factors that regulate the formation of bone, while growth hormone affects a number of factors related to ...

In clinical transplantation, an observed complication is that previous red blood cell (RBC) transfusions may reduce the risk of solid organ transplant rejection but increase the risk of bone marrow transplant (BMT) graft failure (Storb and Weiden, 1981). This statement is seemingly a contradiction. It is difficult to understand how RBC transfusions can both reduce the risk of solid organ transplant rejection and increase the risk of BMT rejection. But this contradiction can be resolved by understanding three considerations. First, the immune system is extremely complex and attempts to control its effects routinely have both positive and negative effects ( ...

Salmeterol is part of a broader group of drugs known as adrenergic agonists; it works specifically by binding to β2 receptors of the adrenergic receptor family, which are activated by the binding of the endogenous neurotransmitters, norepinephrine and epinephrine. The adrenergic receptors are as well part of a broader group of receptors known as G-protein coupled receptors. The G-protein receptor family is composed of a single peptide with seven trans-membrane regions that are attached to a G protein, Gs, Gq, or GI (Harvey & Champe, 2008). The G protein has 3 subunits; the α, β, and γ subunits; the α subunit in the resting state is bound to ...

Part ABriefly discuss the signalling process which occurs when salmeterol binds to its targetReceptor

The receptor to which salmeterol binds The drug salmeterol binds to the active sites of beta-2-adrenergic receptor . This is a category of G protein-coupled receptors. Beta-2-adrenergic receptors have specific actions in the body. They are responsible for the relaxation of smooth muscles relaxation of a non-pregnant uterus, dilation of arteries in the skeletal muscles, contraction of the sphincter muscles and anabolic processes in the skeletal muscle. The receptor has a three dimensional crystallographic structure. The receptors work by ensuring rapid and specific signaling. The receptors couple with Gs G protein, the result being the activation of adenylyl cyclase. The receptors have ...

Cell Mediated Immunity

Cell mediated is one of the components of the immune response. it involves the expression of cells like natural killer cells, phagocytic cells and antigen-presenting cells. it also involves the release of various forms of cytokines. the varies ways by which cell mediated immunity protect the body includes the activation of macrophages and natural killer cells in order to empower them to destroy antigenic agents like pathogens. it also leads to the formation of substances that modulate the function of cells involved in cell-mediated immunity. In addition, cell-mediated immunity helps in protection of the body by leading to activation ...

Introduction

A stroke is a medical condition which is characterized by rapid loss of brain function which is caused by interruption in the blood supply to the various parts of the brain. It can be due to a blockage and it’s known as thrombosis or lack of blood flow known as ischemia or a leakage of blood that is hemorrhage (Feigin, 2005). It results in the person’s inability to move certain parts of the body. The brain is designed in such a way that the right hemisphere always controls the left side of the body while the left hemisphere controls the ...

a) Explain why the effort of hormonal (Endocrine ) control tends to be slow whereas nervous control is usually very fast.

Endocrine control is normally slower when compared to nervous control majorly because hormones once released by the endocrine gland have to travel via the circulation to reach their target receptors on the effector organ which generally takes more time. Meanwhile, information relayed by nerves is in form of impulses (that is, action potentials generated due to electrical excitation produced by a change in the charge across the surface membrane of the neuron evoked by the stimuli) that simply travel along the ...
