[1] The Devils Hole (DH) calcite record from the Great Basin, Nevada, provided the first radiometrically dated time series of late‐Pleistocene climate fluctuations,. In doing so, DH suggested that the penultimate deglaciation, Termination II (T‐II), occurred at 142 ± 3 ka, which is ∼10 kyr before the associated rise in summer insolation, helping to launch the “causality problem” for Milankovitc...
The guanine-nucleotide exchange factor Trio encodes two DH-PH domains that catalyze nucleotide exchange on Rac1, RhoG and RhoA. The N-terminal DH-PH domain is known to activate Rac1 and RhoG, whereas the C-terminal DH-PH domain can activate RhoA. The current study shows that the N-terminal DH-PH domain, upon expression in HeLa cells, activates Rac1 and RhoG independently from each other. In add...
Diuretic hormone 44 (DH) is a bioactive neuropeptide that mediates osmotic balance in a wide variety of insects through increases in cAMP. It is structurally similar to mammalian corticotrophin releasing factor (CRF) peptides. In the moth Manduca and the cricket Acheta, functional studies have shown that its cognate receptor (DH-R) is related to the mammalian CRF receptor. The Drosophila genome...
This paper assesses the performance of dual header pulse interval modulation (DH-PIM) over indoor optical wireless systems. DH-PIM being anisochronous scheme offers a built-in symbol synchronization capability. Theoretical and simulation results demonstrate that DH-PIM offers shorter symbol length, improved transmission rate and bandwidth requirement and a comparable power spectral density prof...
BACKGROUND Dermatitis herpetiformis (DH) is a specific dermatological manifestation of coeliac disease and 80% of DH patients have gluten sensitive enteropathy manifested by crypt hyperplasia and villous atrophy. Matrix degradation mediated by collagenase 1 (MMP-1) and stromelysin 1 (MMP-3) has previously been implicated in the pathobiology of coeliac intestine and cutaneous DH blisters. AIMS...
Introduction: During the last few years, numerous lunar meteorites have been discovered in the Dhofar region of Oman. All of them are lunar highland brec-cias, except for Dhofar 287A, which is a mare basalt. In this paper, we present the first trace-element chemistry of these new lunar highland meteorites: Dhofar 280, 301-310. Mineralogy and petrology of these meteorites have been reported in [...
Geomagnetically induced currents (GICs) in technological conductor systems are a manifestation of the ground effects of space weather. Large GICs are always associated with large values of the time derivative of the geomagnetic field, and especially with its horizontal component (dH/dt). By using the IMAGE magnetometer data from northern Europe from 1982 to 2001, we show that large dH/dt’s (exc...
BACKGROUND No data are available on the incidence of drug hypersensitivity (DH) reactions in outpatient settings of tertiary allergy/immunology clinics. Our aims were to document the frequency of outpatient hospital admissions due to DH reactions to allergy/immunology clinics in adults and the management of these reactions in real life. We also investigated whether drug allergy affected social ...
Although enzymatic hydrolysates of soy protein isolate (SPI) have physiological functionality, partially hydrolyzed SPI exhibits bitter taste depending on proteases and degree of hydrolysis (DH). To determine proteolysis conditions for SPI, it is important to evaluate bitterness during enzymatic hydrolysis. Taste dilution analysis (TDA) has been developed for the screening technique of taste-ac...
Dermatitis herpetiformis (DH), described over 100 years ago, is a life-long blistering skin disease that can appear at any age. Dapsone controls the rash effectively and has been used for over 50 years in the treatment of DH. Major landmark in the research of DH was 30 years ago the discovery of granular IgA deposits in the upper papillary dermis,1 and further differentiation of an autoimmune d...
