Polypeptide Hormones
Produced by:
- Pituitary Gland (e.g., Human Growth Hormone - HGH, Luteinizing Hormone - LH)
- Pancreas (e.g., insulin)
- Hypothalamus (e.g., Growth Hormone-Releasing Hormone - GHRH)

Temporal Adverbials, Aspect, and Event Types in English
In-Adverbials with Simple Past Tense
In-adverbials combined with the simple past tense typically express the 'size' or duration of a [+durative] [+telic] eventuality. As a result:
- With states, they are usually anomalous because states are [–telic].
- With activities, they are usually anomalous because activities are [–telic].
- With accomplishments, which are [+durative] [+telic], they are perfectly natural and express the duration of the event.
- With achievements, which are [–durative], they typically express the time elapsed before the event (onset reading). However, this reading is often more natural with the preposition within.
- With semelfactives, they are usually anomalous because semelfactives are [–durative] [–telic].
In-Adverbials with
...Common STIs: Syphilis, Gonorrhea, Chlamydia
Syphilis
Caused by: The spirochete bacterium Treponema pallidum.
Signs and Symptoms
Primary Stage
Classically presents with a single chancre (firm, painless, non-itchy skin ulceration) that forms approximately 21 days after exposure. These ulcers are usually on the penis, in the vagina, around the anus, and in the mouth. The chancre disappears within 4 to 8 weeks without medication.
Secondary Stage
Diffuse rash which frequently involves the palms of the hands and soles of the feet. May include latent syphilis with few to no symptoms.
Tertiary Stage
Begins after primary and secondary symptoms resolve. Involves neurological or cardiac symptoms. Can lead to difficulties coordinating muscle movements, paralysis, gradual blindness, and death.

...Alice's Encounter with the Caterpillar
Initial Encounter
The Caterpillar and Alice looked at each other for some time in silence. At last the Caterpillar took the hookah out of its mouth, and addressed her in a languid, sleepy voice.
Question of Identity
“Who are YOU?” said the Caterpillar.
This was not an encouraging opening for a conversation. Alice replied, rather shyly, “I—I hardly know, sir, just at present—at least I know who I WAS when I got up this morning, but I think I must have been changed several times since then.”
“What do you mean by that?” said the Caterpillar sternly. “Explain yourself!”
“I can't explain myself, I'm afraid, sir,” said Alice, “because I'm not myself, you see.”
“I'm afraid I can't put it more clearly,” Alice replied very politely,...
