Pollen allergy is characterized by a T(H)2-biased immune response to pollen-derived allergens. However, pollen-exposed epithelia do not encounter pure allergen but rather a plethora of protein and non-protein substances. We demonstrated that pollen liberate lipids with chemical and functional similarities to leukotriens and prostaglandins--the pollen associated lipid mediators (PALMs). To date,...

Three palm species common to southern California landscapes were grown and established under mulch treatments. Turfgrass clippings and Eucalyptus sideroxylon mulches increased the growth of king and queen palms and increased survival of king palms. Although palms growing under fresh eucalyptus mulches did not display nutrient de®ciency symptoms, Mexican fan palm and queen palm were not signi®ca...

H+-ATPase activity in leaves and roots of coconut palms growing in 'root wilt disease-prevalent areas' was compared with that of coconut palms growing in 'disease-free areas'. The activity was found to be significantly less in the leaves and roots of palms in the disease-prevalent zone as compared to that in disease-free zone. Histochemical examination of the leaves showed results that corrobor...

PURPOSE To investigate the association between intraoperative palm temperature change and the curative effect of sympathicotomy. METHODS 49 patients with palmar hyperhidrosis were treated with bilateral endoscopic sympathicotomy. Ipsilateral palm temperature was monitored before and at 3-5 min increments after the sympathetic trunk was transected. The maximum temperature elevation (Tmax) was ...

Oil palm (Elaeis guineensis) is the most productive oil bearing crop worldwide. It has three fruit forms, namely dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), which are controlled by the SHELL gene. The fruit forms exhibit monogenic co-dominant inheritance, where tenera is a hybrid obtained by crossing maternal dura and paternal pisifera palms. Commercial palm oil produ...

A healthy 23-year-old woman presented with a six-month history of white lesions on her palms. The lesions would swell after being in water for 15 minutes and return to baseline 10–15 minutes after drying. The patient did not take medications except for oral contraceptive pills, and she was not aware of a family history of similar complaints. Physical examination showed white, slightly transluce...

Sir, Spiny keratoderma is a rare disease characterized by keratotic spicules resembling a “music box spine” located on the palms and soles (1). This entity has been reported under several different names, such as punctate keratoderma (2), punctate porokeratotic keratoderma (3), palmar filiform hyperkeratosis (4), and spiny keratoderma of the palms and soles (1). We present here a case of spiny ...

Fruiting phenologies of two species of palms,Astrocaryum standleyanum L. H. Bailey and Attalea butyracea (Mutis ex L. f) Wess. Boer, isolated on eight small (1.7–3.7 ha) forested islands in the Panama Canal were studied over a 33-month period. Individual palms were permanently marked with numbered aluminum tags and censused each month for the presence of ripe fruits. The dataset consisted of 11...

This paper studies force-closure grasps of rigid objects by using two palms. The two palms are instrumented with tactile sensors capable of detecting the presence of contacts, and are assumed to be respectively installed on two robotic manipulators capable of motion and force control. Established in this paper is an existence condition under which the two palms form a force-closure grasp. The s...

Although object perception is typically associated with the parvocellular (P) pathway, a form of fast "gist" object perception may be due to activity in the magnocellular (M) pathway (Kveraga et al., 2007). Because the M-pathway is typically associated with action, we hypothesized that manipulations of action would influence speeded object perception. In three experiments, participants indicate...
