Things To Know About Malaria

Malaria is an infectious disease caused by a eukaryotic parasite transmitted by mosquitoes. The parasite is called Plasmodium. Malaria is a primary cause of illness and death that endangers more than 3 billion people worldwide. In severe malaria, organs fail to function and metabolic abnormalities occur which lead to serious medical urgencies or fatal consequences.Continue reading “Things To Know About Malaria”

Why Infections From Fungi, Molds, and Yeast Hard To Cure?

When antibiotic medication comes into our mind, we often think of penicillin. Antibiotics similar to penicillin impede with the synthesis of cell wall which is effective in targeting bacteria. Because bacteria have cell wall and eukaryotic cells such as in humans do not, antibiotics are useful for treating bacterial infections. Organisms that are eukaryotes suchContinue reading “Why Infections From Fungi, Molds, and Yeast Hard To Cure?”

Biology Photo: Toxoplasma gondii and Neurotoxoplasmosis

Neurotoxoplasmosis is an infection caused by Toxoplasma gondii parasite. The condition often affects AIDS patients who are immunocompromised resulting in the development of brain abscesses. The parasites are present almost everywhere and cats are the ultimate host. People can become infected by eating meat contaminated with cysts containing inactive form of the parasite shed inContinue reading “Biology Photo: Toxoplasma gondii and Neurotoxoplasmosis”

Types Of Bacterial Meningitis

Bacterial meningitis is a type of meningitis serious enough to cause death and permanent damages. The bacteria that cause the condition enters the central nervous system and may also spread from the throat, nasal cavity, and middle ear. The bacteria that cause the condition are Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, and Streptococcus agalactiae. BacterialContinue reading “Types Of Bacterial Meningitis”

Demyelination Diseases: Multiple Sclerosis and Guillain-Barré Syndrome

Demyelination of axons is caused by several types of diseases including genetic, bacterial infection, and autoimmune disorders. Despite the varied causes, the outcome is similar. The myelin sheath of the axons is degenerated and as a result, the electrical signal travels through the axon at a slower pace. One demyelination-causing disease is multiple sclerosis (MS)Continue reading “Demyelination Diseases: Multiple Sclerosis and Guillain-Barré Syndrome”

Do You Normally Use 10% Of Your Brain?

There are claims that humans only use 10% of their brains. You may have seen a commercial saying that you can unlock the full potential of your mind and use the remaining 90% that were sitting idle. Well, the fact is, this is a myth. Brain activity can be measured using functional magnetic resonance (fMRI)Continue reading “Do You Normally Use 10% Of Your Brain?”

Anesthesia and Endotracheal Intubation Before Surgery

Patients are prepared for general anesthesia before surgery. This includes pre-surgery process of putting the normal homeostatic control on hold. Anesthesiologist takes control of the respiration over the patient’s homeostatic control. The anesthetic drug used relaxes most of the body’s muscle. The breathing and tongue muscles are some of the affected parts during general anesthesia.Continue reading “Anesthesia and Endotracheal Intubation Before Surgery”

Sarcopenia and Aging

Sarcopenia is the irreversible loss of muscle cells due to aging. Even highly trained athletes are susceptible to the condition and this explains the declining of performance as we age. The performance reduction is more observable in people with activity that requires strength and power like sprinting but less observable in people with activity thatContinue reading “Sarcopenia and Aging”

Duchenne Muscular Dystrophy (DMD)

Duchenne muscular dystrophy is a disorder of the muscular system which involves the progressive weakening of the skeletal muscles. The deficiency of the dystrophin protein causes DMD. Dystrophin helps bind the thin filaments of myofibril to the sarcolemma, but with the lack of dystrophin, sarcolemma may tear during muscle contractions which results in the influxContinue reading “Duchenne Muscular Dystrophy (DMD)”

Patellofemoral Syndrome or Runner’s Knee

Patellofemoral syndrome is a common overuse injury for people who are runners. Females have a higher risk and most frequent in teenagers and young adults. The condition develops from too much running especially downhill but also occur in people who do excessive knee bending like jumpers, skiers, cyclist, weight lifters, and soccer players. The primaryContinue reading “Patellofemoral Syndrome or Runner’s Knee”
