The reliability and validity of the Figure of 8 Walk test in older people with knee replacement

The Figure of 8 Walk (F8W) test looks at walking in straight and curved paths in both clockwise and anti-clockwise directions (Fig. 1). The time taken to carry out the test is recorded along with the number

Kelp extracts and their pharmaceutical properties

Kelp extracts and their pharmaceutical properties. AoS

Kelps are a specific type of large brown seaweeds that generally grow on rocky, shallow, nutrient-rich ocean water. The most common examples of kelps found in the South African coastlines include Ecklonia maxima (sea bamboo) (Fig. 1), Ecklonia

When toxicity goes circular: Isoprostanes as markers and effectors of oxidative stress

When toxicity goes circular: Isoprostanes as markers and effectors of oxidative stress. AoS

In normal conditions, there is a dynamic equilibrium between oxidants and antioxidants in the human body; however, when there is an unbalance in this redox state, oxidative stress occurs.  In an unbalanced state, the peroxidation of polyunsaturated

A new link between oxidant stress and lung cancer

A new link between oxidant stress and lung cancer. AoS

DNA repair protects our cells from conditions that cause damage to the genome, which can become a threat to the maintenance and function of our tissues. Our cells have a variety of DNA repair systems.  Most frequent

Enlightening the importance of the NDRGs in the (cancerous) gut

Enlightening the importance of the NDRGs in the (cancerous) gut. AoS

The gastrointestinal (GI) tract is one of the most complex organs of the human body. With its approximate 5m length, a diversity of specialized epithelial cell types (the ‘lining’ of the GI tract), about 80% of our

Physiological brainwashing

Physiological brainwashing. AoS

There is a barrier in the brain, known as the blood-brain barrier, which strictly regulates the exchange of substances between the blood and this organ. The blood-brain barrier restricts the passage of drugs into the brain and

Hydrogen storage in lithium-terminated boron chains

Hydrogen storage in lithium-terminated boron chains

Hydrogen can be used as alternative energy source because of many advantages. Despite the high energy content by mass, hydrogen has low density, and it is necessary to develop an efficient storage medium to use this technology

Zinc promotes myoblast differentiation activating Zip7 transporter and Akt signalling pathway

Skeletal muscle is a heterogeneous, dynamic and plastic tissue, which comprises 40% of adult human body mass. Through contraction and relaxation, skeletal muscles provide movement and stability to the body. Besides the mechanical function, muscle tissue also

Non-traditional cup-plant crop as a prospective substitute for maize at biogas production

Non-traditional cup-plant crop as a prospective substitute for maize at biogas production. AoS

Biogas is a renewable fuel produced from the decomposition of organic materials at anaerobic digestion in special units known as biogas plants. The application of biogas is oriented to heat or electricity generation using the combustion process.

How to improve workers’ satisfaction: The promise of emotional intelligence and work engagement

How to improve workers’ satisfaction. AoS

There is an increased attention paid to which psychological factors help individuals to deal with their daily work-related demands so they feel healthier, happier, and more satisfied at their work. Job satisfaction is a multidimensional psychological response

Exploring early mechanotransduction responses

Exploring early mechanotransduction responses. AoS

Mechanical stress plays a key role in cellular behaviour and fate, affecting the correct development and functionality of tissues and organs. Due to the complexity of the in vivo cellular environment, most mechanotransduction research relies on the

Proteins identified in the immune system of crayfish

Proteins identified in the immune system of crayfish. AoS

Invertebrates characteristically only possess mechanisms of innate immunity, both cellular and humoral, that appear to be activated depending on the pathogens involved. These defense mechanisms are triggered by the activation of the pathogen recognition receptors (PRR). The

The dental nerve circulates in a canal within the mandible

The dental nerve circulates in a canal within the mandible. AoS

The inferior alveolar nerve (IAN) is a sensitive branch of the trigeminal nerve, the 5th pair of cranial nerves. It has an intraosseous path in the mandible, inside the mandibular canal, where it is accompanied by lymphatic,

How processing types change the elemental composition of rice?

According to FAO – Food and Agriculture Organization of the United Nations, world’s rice production reached 501.2 million tonnes in 2016-17 season, which is related to rice being a staple for 7 billion people. Asia is the

Grisel’s syndrome linked to mycoplasma pneumoniae infection

Grisel’s syndrome is a no traumatic atlanto axial subluxation often linked to inflammatory conditions of the head and neck region. The subluxation involves the connection between the first and the second cervical vertebrae   and is recognized to

Inside out: treating infants with gastroschisis

For many parents the first images of their baby on the ultrasound is a joyful time. How many fingers? How many toes? Is it a boy or a girl? For some families however, they are told that

Risk due to explosion of the tank with LPG

Accident events that lead to tank explosion include Boiling Liquid Expanding Vapor Explosion (BLEVE), Mechanical Explosion (ME), Confined Explosion (CE) and Runaway Reaction (RR). Accidents that are accompanied by the explosion of the tank are distinguished by

HIV-1 alters mitochondria in neurons and contributes. AoS

Human immunodeficiency virus type-1 (HIV) enters the brain during the initial stages of infection and can cause neurologic dysfunction. Despite the success of HIV treatment through combination antiretroviral therapy (ART), impaired neurocognitive function remains an important problem

Access to modified peptides with heterocycle backbones using combinatorial chemistry

Applications of peptides in medicinal chemistry have several inherent limitations which can be resolved by use of peptide-like molecules. The cleavage of amide bond by proteases, low permeability, rapid metabolic processing, excretion and unwanted side effects are
