Despite wide temporal and regional diversity of rotavirus strains being reported throughout the Indian subcontinent, a study based in Lahore, Pakistan identified the G2P and G9 genotypes as the most prevalent among children suffering acute gastroenteritis.2 Nevertheless, it has been shown that rotavirus vaccines (Rotarix and Rotateq) generate heterotypic immune response, providing equivalent efficacy against a vast range of rotavirus genotypes.
However, these lower titers most likely are due to the [sG.sub.HeV] vaccine being heterotypic because the [PRNT.sub.50] titers against HeV in a similar African green monkey study were 640-1,280 on day of challenge (28).

A broad spectrum of lesions can be considered in differential diagnosis: infections, ranula, obstruction of the submandibular duct, tumors of the sublingual and other minor salivary glands, lymphadenopathy, thyroglossal duct cysts, lymphatic malformations, epidermoid cysts, neurofibromas, hemangiomas, heterotypic gastrointestinal cysts, foregut duplication cysts [1, 4, 5, 9].
Since introduction of OPV in 1961, the cumulative iVDPV serotype distribution is iVDPV2 (66%), iVDPV3 (17%), iVDPV1 (12%), and heterotypic mixes (i.e., types 1 and 2 or types 2 and 3) (5%).
Although caruncles are usually benign, they should be surgically excised and histopathologically examined since they may be the indicators of lymphoma, clitoral venous thrombosis, urethral thrombosis, pseudoneoplastic lesions, urethral polyps, malign melanoma, intestinal heterotypic, angiomatous lesions, and diastolic urethral stenosis (5,6,7,8,9,10,11).
Thymic nurse cells participate in heterotypic internalization and repertoire selection of immature thymocytes; their removal from the thymus of autoimmune animals may be important to disease etiology.
Heterotypic spheroids reflect tissue environments in vivo, and, at least theoretically, permit construction of larger tissue models by higher order assembly of individual spheroids.
According to researchers, early signs of BD can fall into a relatively characteristic "homotypic" pattern, consisting mainly of symptoms or other features associated with mood disorders; or a "heterotypic" pattern of other symptoms including anxiety and disruptive behaviour.
have used FluidFM-based SCFS to compare both homotypic (between MCF7 breast cancer cell line) and heterotypic adhesion forces (between MCF10A breast cancer cells and nontumorigenic HS5 cells).
