Which gland in the male and female reproductive tracts perform similar functions? What cell type regulates spermatogenesis in the testes? Which gland does not produce reproductive hormones? Which type of gland fits this description: duct from the ovary that carries the ovum (egg) to ...
Explain why the actions of the thymus demonstrate a close functional connection between the lymphatic system and the endocrine system.Thymus:The thymus is a gland located in the heart of the chest. Its main function is to produce and secr...
thymus description and microphotography are showed in Figure 1A-B. A fully functional thymus contains 10% of immature precursors and 15% of mature thymocytes waiting to reach the bloodstream as naive (antigen-inexperienced) TL. Remaining 75% of the thymocytes are in an intermediate maturation step...
Description: Thyme is valued for its antiseptic and antioxidant properties, and it is an excellent tonic and is used in treating respiratory diseases and a variety of other ailments. The flowering tops are anthelmintic, strongly antiseptic, antispasmodic, carminative, deodorant, diaphoretic, ...
In this chapter, after a brief description of the role of the thymus for immunity, its involution during ageing and the impact on the immunity in the elderly are described. Furthermore, I will discuss attempts to boost thymus function aiming at a rejuvenation of the "old" immune system....
The recent description of tolerance susceptible (TS) and resistant (TR) mice derived by equilibrated intercrossing of eight separate mouse strains and which show opposite phenotypes for oral tolerance induction for several antigens may offer important insights into the polygenic control of the ...
We identified a gap in the availability of volumetric qualitative and quantitative information on the microarchitecture of the thymic structural components (i.e., cortex, medulla and HBs) that can reflect alterations in thymic function under different circumstances. To address this gap, there have bee...
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings). ...
Studies on the immune system of fishes have focused on a relatively small number of species, principally among the teleosts. This summary will be confined mainly to the description of the major lymphoid organs in the teleosts, while the lymphoid organs in some other fishes will be mentioned brie...
the involution, or shrinking, of the thymus, the cortex becomes thin. Lymphocytes disappear and are replaced byfat tissuefrom thepartitionsbetween the lobules. The process of involution is never complete, and the bits of thymus tissue that remain are probably sufficient to maintain its function. ...
