The Ab repertoire is not uniform. Some variable, diversity, and joining genes are used more frequently than others. Nonuniform usage can result from the rearrangement process, or from selection. To study how the Ab repertoire is selected, we analyzed one part of diversity generation that cannot be driven by the rearrangement mechanism: the reading frame usage of DH genes. We have used two high-...

Dendrobium huoshanense is a valuable and versatile Chinese herbal medicine with the anecdotal claims of cancer prevention and anti-inflammation. However, its immunological activities are limited to in vitro studies on a few cytokines and immune cell functions. First, we investigated the effects of polysaccharides isolated from DH (DH-PS) on inducing a panel of cytokines/chemokines in mice in vi...

Landraces are valuable genetic resources for broadening the genetic base of elite germplasm in maize. Extensive exploitation of landraces has been hampered by their genetic heterogeneity and heavy genetic load. These limitations may be overcome by the in-vivo doubled haploid (DH) technique. A set of 132 DH lines derived from three European landraces and 106 elite flint (EF) lines were genotyped...

Neuropeptides play essential roles in a variety of physiological responses that contribute to the development and reproduction of insects. Both the diapause hormone (DH) and pheromone biosynthesis activating neuropeptide (PBAN) belong to the PBAN/pyrokinin neuropeptide family, which has a conserved pentapeptide motif FXPRL at the C-terminus. We identified the full-length cDNA encoding DH-PBAN i...

BACKGROUND Dentin hypersensitivity (DH) is a common problem encountered in clinical practice. The purpose of this study was to identify the management approaches for DH among United States dentists. METHODS One hundred eighty five National Dental Practice-Based Research Network clinicians completed a questionnaire regarding their preferred methods to diagnose and manage DH in the practice set...

A facile synthesis and biological applications of silver (DH-AgNps) and gold nanoparticles (DH-AuNps) mediated by the aqueous extract of Angelicae Pubescentis Radix (Du Huo) are explored. Du Huo is a medicinal root belonging to Angelica pubescens Maxim which possesses anti-inflammatory, analgesic, and antioxidant properties. The absorption spectra of nanoparticles in varying root extract and me...

Dermatitis herpetiformis (DH) is an extraintestinal manifestation of coeliac disease. The burden of illness in untreated coeliac disease is known to be considerable, but corresponding evidence for DH is lacking. In this study the burden of DH was evaluated prospectively in 52 patients newly diagnosed with DH using a study questionnaire and a validated Psychological General Well-Being (PGWB) que...

Introduction: Several lunar highland meteorites were found in the Dhofar region of Oman. Here we report the first data on the petrography and mineralogy of four new lunar stones, Dhofar 304, 305, 306 and 307. Dh-304 was found close to Dh-025 and 301, whereas Dh-305, 306 and 307 were recovered nearby Dh-081, 280, 302 and 303. The new meteorites are moderately weathered, impact-melt breccias. No ...

Dermatitis herpetiformis (DH) is a cutaneous manifestation of coeliac disease. Increased bone fracture risk is known to associate with coeliac disease, but this has been only scantly studied in DH. In this study, self-reported fractures and fracture-associated factors in DH were investigated and compared to coeliac disease. Altogether, 222 DH patients and 129 coeliac disease-suffering controls ...

INTRODUCTION Since the beginning of the HIV epidemic in Ceará, disseminated histoplasmosis (DH) has often been detected among AIDS patients. METHODS In order to investigate the clinical and laboratory characteristics, evolution and survival of cases of DH/AIDS coinfection, the medical records on 134 cases of DH admitted to a reference hospital in Ceará between 1999 and 2005 were analyzed. R...
