individuals under stress or with compromised immunity.

PathologyMcroscopic picture of red blood cells (RBCs) in thalassemia, the following
characteristics are typically observed:
Microcytic: The RBCs are smaller than normal (microcytic)
due to the reduced hemoglobin content.
Hypochromic: The RBCs have a lower concentration of
hemoglobin, leading to a paler appearance (hypochromic).
Target cells: These are RBCs that have a bullseye
appearance due to an abnormal distribution of hemoglobin within the cell.
Target cells are often seen in thalassemia due to the imbalance of globin
chains and the resultant membrane changes.

Oral MedicinePenciclovir is the correct answer as it is not available in a cream formulation. Acyclovir and docosanol are available in cream formulations for the treatment of cold sores. Lysine is an amino acid supplement that may help reduce the frequency of herpes outbreaks but is not a medication specifically designed to treat herpes labialis.

Oral PathologyPeriapical granulomas were diagnosed as well-circumscribed periapical
radiolucency measuring less than 1.5 cm in diameter, periapical cysts were
characterized by well-defined periapical radiolucency with sclerotic borders
measuring greater than 1.5 cm, and periapical abscesses were characterized by
ill-defined periapical radiolucency with diffuse margins.
While bone resorption can occur in the presence of a periapical granuloma, it
is not a prerequisite for its formation. A periapical granuloma can develop in
response to pulp necrosis or infection without necessarily requiring bone
resorption to occur first. The granuloma can form as a reaction to the
inflammatory process, regardless of the state of the surrounding bone.

PhysiologyThe primary mechanism of H+ secretion by parietal cells is through the action of the H+-K+ ATPase pump, also known as the proton pump. This enzyme is responsible for actively transporting H+ ions into the gastric lumen while moving K+ ions into the cells, thereby acidifying the gastric content.
