Airway eosinophilic inflammation is a characteristic feature of allergic asthma. Exposure to allergens produced by the German cockroach (Blattella germanica) is a risk factor for allergic disease in genetically predisposed individuals, and has been linked to an increase in asthma morbidity among cockroach-sensitive inner city children. To determine the role and contribution of specific HLA clas...

AIM To evaluate German cockroach (Blattella germanica) allergen levels in house dust and skin reactivity to German cockroach in adult atopic and non-atopic subjects in inland areas of Croatia. METHODS Blattella germanica group 2 (Bla g 2) allergen was measured using the enzyme-linked immunosorbent assay (ELISA) on test strips (Dustscreen(TM) test, Heska AG, Switzerland) in 94 house dust sampl...

An all-chain-wireless brain-to-brain system (BTBS), which enabled motion control of a cyborg cockroach via human brain, was developed in this work. Steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI) was used in this system for recognizing human motion intention and an optimization algorithm was proposed in SSVEP to improve online performance of the BCI. The cyborg...

Abstract The German cockroach (Blattella germanica ) is a pest often found in apartments, houses, food-handling areas, hospitals, and healthcare facilities Indonesia. It searches for food dirty places such as trash cans, sewers, septic tanks. will feed on almost anything, including fecal matter humans. So, this habit causes the can act vector several pathogenic bacteria increases risk of variou...

BACKGROUND Exposure to cockroach allergen is prevalent in inner-city homes and is associated with an increased risk of cockroach sensitization. OBJECTIVE We sought to determine the prevalence of cockroach allergen exposure in suburban middle-class homes and to study its relationship to cockroach sensitization. METHODS Children with asthma, 6 to 17 years of age, were recruited from 3 pediatr...

Inspired by nature’s effective use of tactile feedback for rapid maneuvering, we have designed a passive, highly compliant tactile sensor for Sprawlette, a hexapedal running robot. To bridge the gap between between biology and design, we have taken initial steps toward understanding how the cockroach, Periplaneta americana, uses antenna feedback to control its orientation as it runs along a wal...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...
