Regulation of MHC class II gene expression by the class II transactivator
Nature Reviews Immunology, 2005MHC class II molecules are pivotal for the adaptive immune system, because they guide the development and activation of CD4+ T helper cells. Fulfilling these functions requires that the genes encoding MHC class II molecules are transcribed according to a strict cell-type-specific and quantitatively modulated pattern.

Correction of Class II malocclusion with Class II elastics: A systematic review
American Journal of Orthodontics and Dentofacial Orthopedics, 2013Although Class II elastics have been widely used in the correction of Class II malocclusions, there is still a belief that their side effects override the intended objectives. The aim of this systematic review was to evaluate the true effects of Class II elastics in Class II malocclusion treatment.A search was performed on PubMed, Scopus, Web of ...

Root resorption in Class II malocclusion treatment with Class II elastics
American Journal of Orthodontics and Dentofacial Orthopedics, 2016The objective of this investigation was to compare the amount of apical root resorption in nonextraction treatment of Class II malocclusions with and without Class II elastics.A sample of 54 patients with Class II Division 1 malocclusion, retrospectively selected, was divided into 2 groups.

[structures: see text] A class II aldolase-mimicking synthetic polymer was prepared by the molecular imprinting of a complex of cobalt (II) ion and either (1S,3S,4S)-3-benzoyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (4a) or (1R,3R,4R)-3-benzoyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (4b) in a 4-vinylpyridine-styrene-divinylbenzene copolymer ...

Class II antiarrhythmic agents
Pharmacology & Therapeutics, 1988The concept of/3-adrenoceptors stems from work published by Ahlquist (1948) following a systematic study of the effects of five catecholamines. He found that these compounds had a specific order of potency in eliciting excitatory responses, such as the contraction of smooth muscle of the iris, blood vessels and sphincters.

Journal of Esthetic and Restorative Dentistry, 2001
Improvements in adhesive materials and techniques have contributed to the clinical success of posterior composite restorations. However, even with those improvements, the gingival margin of a Class II composite restoration remains a difficult area to seal predictably and therefore represents a potential location for failure.

Immunology Today, 1992
H-2O is a recently described non-polymorphic mouse MHC class II molecule. Here, Lars Karlsson and colleagues describe the discovery of the H-2Ob and H-2Oa loci and the pattern of expression of H-2O, and speculate on the possible function of this unusual molecule.

An Extension of a Class of Polynomials. II
SIAM Journal on Mathematical Analysis, 1971In this paper we study the algebraic structure of the class of polynomials $\{ u_n !H_n (x)\} $ in x, where $\{ {H_n (x)} \}$ satisfies the functional equation $D_u H_n (x) = H_{n - 1} (x)$ for $n = 1,2, \cdots $, and where $D_u $ is a general operator, linear and distributive, which transforms a polynomial of degree n in x into one of degree $n - 1 ...

Class II treatment in orthodontics
American Journal of Orthodontics, 1976T he diagnosis, treatment, and retention of Class II malocclusions have been a constant source of study and discussion since they comprise a large segment of an orthodontist’s practice. Treatment results may range from successes to improvements to failures.

Soluble HLA class I and class II in Japanese
Human Immunology, 1994Soluble human leukocyte antigens (sHLA) class I (sHLAI) and class II (sHLA-II) in sera or plasma can be quantitatively measured by enzyme-linked immunosorbent assay (ELISA) [1, 2]. Several reports state that individuals with particular HLA allotypes have a higher sHLA-I concentration than those without that particular allotype [1-5].
