The EEG (electroencephalogram) is a test that detects electrical activity in the brain using sensors placed along the scalp. It was one of the earliest brain imaging techniques, with the first human EEG recorded in 1924. During a typical EEG, electrodes are placed on the head according to the international 10-20 system and the brain's electrical activity is recorded as the patient performs various tasks like hyperventilating or having a light shone in their face. The EEG is noninvasive, portable, and able to detect changes in brain activity with good temporal resolution, though it has limited spatial resolution.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
IGE has developed a technology to convert waste plastics into fuels like diesel, petrol and LPG through a catalytic restructuring process combined with an indirectly fired gas turbine. They have demonstrated this technology at a 40 tonne per day plant. IGE plans to build 4 commercial plants over 3 years to process 126,000 tonnes of waste plastics annually, diverting plastic from Australian landfills. The business model relies on low costs from proven technologies and selling fuel products to meet Australian standards to sophisticated fuel users and blenders, without subsidies or tipping fees.

Sleep physiology and EEG waves in humans PPTAnupamaDeepak2
EEG records electrical activity of the brain through electrodes placed on the scalp. It detects brain waves including alpha, beta, theta, and delta waves which are characterized by their frequencies and amplitudes. EEG is used to diagnose epilepsy and help localize brain tumors. Sleep involves cycles of NREM and REM sleep. NREM sleep has 4 stages and is characterized by slowing of brain activity and reduced muscle tone. REM sleep involves desynchronized brain activity similar to being awake and causes paralysis of muscles except eyes and diaphragm. Disorders include insomnia, sleepwalking, narcolepsy, sleep apnea, and REM behavior disorder.
The document discusses electroencephalography (EEG), which records the electrical activity of the brain from the scalp. It describes how Hans Berger first recorded EEG in 1929. It explains the different types of brain waves seen in a normal EEG - alpha, beta, theta, and delta waves. It discusses how EEG is used to study epilepsy, sleep disorders, brain tumors, and other neurological conditions. It also covers how EEG recordings are performed, including electrode placement and provocation tests.
Electroencephalography is the technique used to acquire electrical signals of brain through electrodes which are placed by certain montage. Different wave patterns can be observed which is useful in detecting any abnormal conditions or neurological brain disorders in human beings. There is broad future scope for medical research and creating EEG based equipments for real time applications.

GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

This guideline is directed principally toward new Molecular Entities that are
likely to have significant use in the elderly, either because the disease intended
to be treated is characteristically a disease of aging ( e.g., Alzheimer's disease) or
because the population to be treated is known to include substantial numbers of
geriatric patients (e.g., hypertension).
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
