Serial transverse sections were cut through the foregut
at the following developmental stages: larvae at hatching and at 8, 13, 24, 31, 42, and 49 days post-hatching (one to four specimens each) and post-larvae at 6, 12, 24, and 48 h after velum loss and 3, 4, and 5 days after velum loss (two specimens each).
Neuroenteric cysts are foregut
duplication cysts associated with vertebral anomalies.
analyses of many commercially important shrimps have shown that penaeid shrimps are omnivorous and benthic faunas are dominant in their diet followed by detritus [1-5].
The mechanism by which exclusion of the duodenum and upper jejunum reverses diabetes (the so-called foregut
theory) has not been fully explained, and "without data regarding the change in gut hormones, such as glucagon, gastric inhibitory peptide, and glucagon-like peptide 1, we cannot elucidate the underlying mechanisms," the investigators added.
His special interests are in benign and malignant diseases of the foregut
The saliva of the Guatemalan potato moth larvae (Tecia solanivora), a major pest, which forces many farmers to spray plants with pesticides in South America, contains compounds in its foregut
that elicits a system-wide response in the Colombian Andes commercial potato plant (Solanum tuberosum), researchers have found.
The high-risk procedures included nonesophageal thoracic surgery, which had a 3.8-fold risk of postoperative pneumonia, compared with the lowrisk operations, and aortic (2.6), intestinal (2.5), brain (2.9), foregut
and hepatopancreatobiliary (4.1), and other abdominal operations (2.1).
No other abnormalities of the foregut
The proventriculus is an organ situated between the foregut
and midgut, its lumen lined by cuticle with teeth-like projections.
(1990), Wolfe and Felgenhauer (1991), Mikami and Takashima (1993) and Lemmens and Knott (1994), in which substantial morphological changes occurred in the digestive system during metamorphosis by the reduction of mandibles and the number of setae in the mouthpart appendages and poorly developed foreguts
. Abrunhosa and Kittaka (1997a,b) reported similar observations during non-feeding stages in megalopae (transitory stage) of Paralithodes crabs (an important fishing resource of the Northern Pacific) related to the poorly developed feeding appendages (mouthparts and foregut
) and, more recently, during the zoeal stages of the thalassinid Lepidophthalmus siriboia Felder and Rodrigues, 1993.
These are also known as bronchopulmonary foregut
malformations, comprising congenital cystic adenomatoid malformation (CCAM), congenital pulmonary airway malformation (CPAM), congenital lobar emphysema (CLE), broncho pulmonary sequestrations (BPS) and bronchogenic c ysts.
Then, 21 tissues (telencephalon, hypothalamus, mesencephalon, cerebellum, myelencephalon, liver, spleen, heart, eye, skin, foregut
, gill, white muscle, hindgut, midgut, red muscle, trunk kidney and gonad) were removed immediately and stored in liquid nitrogen.
