OBJECTIVE To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and D. farinae in pediatric patients with atopic dermatitis (AD), and to assess the therapeutic value of using acaricides with other environmental anti house dust mites (HDM) measures. METHODS Ninety-eight children with AD were chosen randomly from the Pediatric Allergy Clinic in Al-Noor Hospital, Khal...

Background. Bronchial smooth muscle cells (BSMC) are a major source of proinflammatory and proangiogenic cytokines and chemokines, including VEGF and CXC-chemokines. CXC-chemokines act primarily on neutrophils, mediating their recruitment to and activation at the site of inflammation. In humans, house-dust mite (HDM) allergens can cause asthmatic exacerbations and trigger an inflammatory respon...

Epidemiological studies indicate that cigarette smoke exposure is a risk factor for increased sensitisation and asthma development. The aim of this study was to examine the impact of cigarette smoke on sensitisation and allergic airway inflammation in response to a low dose of house dust mite (HDM), and to obtain potential mechanistic insights. Mice were exposed to low doses of HDM extract comb...

BACKGROUND AND PURPOSE When house dust mite (HDM), a common allergen, comes into the mucosal membrane, it may stimulate innate immunity. However, the precise role of interleukin- (IL-) 25 in the development of HDM-induced nasal allergic inflammation is still unclear. Therefore, we investigated the role of IL-25 in allergic rhinitis (AR) patients sensitized to HDM. METHODS To confirm the produ...

The HDM-4 aids in estimating the deterioration of pavement as well intricate interactions between environment, vehicles, surface, and structure pavement. It predicts how roads will deteriorate over time due to increased traffic. current study was carried out at Hyderabad, particularly which are subjected heavy adopted for Dhulapally Bahadurpally (DB), Gandimaisamma Bowrampet (GB), Medchal (GM),...

Crustacean shellfish allergy is an important cause of food allergy and anaphylaxis in Asia. The major allergen in shellfish allergy is tropomyosin, a pan-allergen that is also found in house dust mites and cockroaches. Tropomyosins from house dust mites (HDMs) have a high sequence homology to shellfish tropomyosins, and cross-reactivity between HDM and shrimp tropomyosins has been demonstrated....

Experimental mouse models of asthma have broadened our understanding of the mechanisms behind allergen-induced asthma. Typically, mouse models of allergic asthma explore responses to a single allergen; however, patients with asthma are frequently exposed to, and tend to be allergic to, more than one allergen. The aim of the current study was to develop a new and more relevant mouse model of ast...

House dust mite (HDM) is the major source of allergen in house dust and is strongly associated with the development of asthma. HDM can evoke a direct, nonallergic inflammatory reaction in vitro. We aimed to determine whether this apparent nonallergic, inflammatory response can be observed in a more complex in vivo setting. Vehicle, Alum or HDM (Dermatophagoides pteronyssinus 5 microg, i.p. with...

The anticancer peptide PNC-27, which contains an HDM-2-binding domain corresponding to residues 12-26 of p53 and a transmembrane-penetrating domain, has been found to kill cancer cells (but not normal cells) by inducing membranolysis. We find that our previously determined 3D structure of the p53 residues of PNC-27 is directly superimposable on the structure for the same residues bound to HDM-2...

BACKGROUND Antibody Directed Enzyme Prodrug Therapy (ADEPT) can be used to generate cytotoxic agents at the tumor site. To date non-human enzymes have mainly been utilized in ADEPT. However, these non-human enzymes are immunogenic limiting the number of times that ADEPT can be administered. To overcome the problem of immunogenicity, a fully human enzyme, capable of converting a non-toxic prodru...
