Length of semitendinosus and gracilis tendons and the relationship of graft length and leg length.

Background: Hamstring tendon has been more popularly used in anterior cruciate ligament reconstruction. Quadruple semitendinosus graft had some benefits and decreased the donor site morbidity.

Objective: This study presented the length of semitendinosus and gracilis in Thai people and used the leg length to estimate the tendon graft length.

The location of pes anserinus insertion in Thai people.

Background: The semitendinosus and gracilis tendon are commonly used for ligamentous reconstruction. Inaccurate skin incision may cause complications such as cutting the main tendon, inadequate graft length and sciatic nerve injury. There have been no reports about the insertion site of these tendons among Thai people.

Molecular characterization and analysis of a truncated serotonin receptor gene expressed in neural and reproductive tissues of abalone.

In molluscs, the neurotransmitter serotonin (5-HT) has been linked to a variety of biological roles including gamete maturation and spawning. The possible involvement of 5-HT in abalone gamete release was demonstrated by a dose-dependent increase in Haliotis rubra gonad contractile bioactivity following 5-HT stimulation. Physiological functions associated with 5-HT, are mediated through binding to 5-HT receptors.

Presence of arylsulfatase A and sulfogalactosylglycerolipid in mouse ovaries: localization to the corpus luteum.

Arylsulfatase A (AS-A) is a lysosomal enzyme, which catalyzes the desulfation of certain sulfogalactolipids, including sulfogalactosylglycerolipid (SGG), a molecule implicated in cell adhesion. In this report, immunocytochemistry revealed the selective presence of AS-A in the corpus luteum of mouse ovaries. Immunoblotting indicated that mouse corpus luteum AS-A had a molecular mass of 66 kDa, similar to AS-A of other tissues.

Egg-laying-hormone immunoreactivity in the neural ganglia and ovary of Haliotis asinina Linnaeus.

Immunoreactivity against the abalone egg-laying hormone (aELH) was detected in the fine granules of type 1 and 2 neurosecretory (NS) cells, neurites in the neuropil, and blood sinuses in the connective tissue sheath of the cerebral, pleuropedal, and visceral ganglia of the tropical abalone, Haliotis asinina Linnaeus. The number of positive NS cells, and the intensity of staining in the ganglia, varied and might be related to the stage of ovarian cycle. At any stage, positive cells were most numerous in the pleuropedal, and least numerous in the visceral ganglion.
