NEETMDSThe plateau phase is a sustained depolarization during the action potential, which is a characteristic feature of cardiac muscle cells, including those in the Purkinje fibers, atria, and ventricles. It is caused by the prolonged opening of voltage-gated calcium channels. Among the options provided, Purkinje fibers exhibit this phase.

A white patch on the maxillary ridge, especially in an older patient, should be treated with suspicion for a potentially premalignant or malignant lesion. An immediate biopsy is necessary to establish a definitive diagnosis before proceeding with any prosthetic treatment like preparing a denture.

Dental Materials
In orthodontics, wires with a low load deflection rate are typically preferred for areas requiring large tooth movements because they provide a more constant force as the tooth moves and the appliance is deactivated. This constant force is beneficial for controlling the rate of tooth movement.

Chronic hepatitis, often caused by viral infections such as hepatitis B and C, can persist for years and may lead to chronic inflammation, liver fibrosis, and in some cases, cirrhosis or liver cancer.

Oral Pathology
Diphtheria serious bacterial infection that usually affects the mucous
membranes of the nose and throat.
Diphtheria signs and symptoms usually begin 2 to 5 days after a person becomes
infected. Signs and symptoms may include:
A thick, gray membrane covering the throat and tonsils
A sore throat and hoarseness
Swollen glands (enlarged lymph nodes) in the neck
Difficulty breathing or rapid breathing
Nasal discharge
Fever and chills
Tiredness
Skin (cutaneous) diphtheria
A second type of diphtheria can affect the skin, causing pain, redness and
swelling similar to other bacterial skin infections. Ulcers covered by a gray
membrane also may be a sign of skin diphtheria.

SOLUTION NSAIDS, i.e. Brufen, etc. inhibit tooth movement as they interfere with production of prostaglandins.
• Nimesulide does not interfere with PG production and so can be safely given during tooth movements.

Physiology
The primary mechanism for sodium reabsorption in the distal tubules and collecting ducts is sodium-hydrogen exchange, which occurs through the NHE3 transporter. This allows for the reclamation of sodium while maintaining the acid-base balance by exchanging sodium for hydrogen ions, which are then secreted into the tubular lumen.
