A length-dependent neuropathy with pain in the feet is a common complication of diabetes (painful diabetic neuropathy, PDN). It was hypothesized that pain may arise from sensitizedhyperactive cutaneous nociceptors, and that this abnormal signaling may be reduced by topical administration of the α 2 -adrenergic agonist, clonidine, to the painful area. This was a randomized, double-blind, placebo-controlled, parallel-group, multi-center trial. Nociceptor function was measured by determining thedoi:10.1016/j.pain.2012.04.014 pmid:22683276 pmcid:PMC3413770 fatcat:fitgc4so5fbrzlyx4kxnrjt6n4

Subjects were then randomized to receive 0.1% topical clonidine gel (n=89) or placebo gel (n=90) applied t.i.d. to their feet for 12 weeks. The difference in foot pain at week 12 in relation to baseline, rated on a 0-10 numerical pain rating scale (NPRS), was compared between groups. Baseline NPRS was imputed for missing data for subjects who terminated the study early. The subjects treated with clonidine showed a trend toward decreased foot pain compared to the placebo-treated group (the primary endpoint; p=0.07). In subjects who felt any level of pain to capsaicin, clonidine was superior to placebo (p<0.05). In subjects with a capsaicin pain rating ≥2 (0-10, NPRS), the mean decrease in foot pain was 2.6 for active compared to 1.4 for placebo (p=0.01). Topical clonidine gel significantly reduces the level of foot pain in PDN subjects with functional (and possibly sensitized) nociceptors in the affected skin as revealed by testing with topical capsaicin. Screening for cutaneous nociceptor function may help distinguish candidates for topical therapy for neuropathic pain.

Recent warming has caused changes in species distribution and abundance 1±3 , but the extent of the effects is unclear. Here we investigate whether such changes in highland forests at Monteverde, Costa Rica, are related to the increase in air temperatures that followed a step-like warming of tropical oceans in 1976 (refs 4, 5). Twenty of 50 species of anurans (frogs and toads) in a 30-km 2 study area, including the locally endemic golden toad (Bufo periglenes), disappeared following synchronousdoi:10.1038/19297 fatcat:6ydmhe75uzdbbloqel3y5jaqn4

Our results indicate that these crashes probably belong to a constellation of demographic changes that have altered communities of birds, reptiles and amphibians in the area and are linked to recent warming. The changes are all associated with patterns of dry-season mist frequency, which is negatively correlated with sea surface temperatures in the equatorial Paci®c and has declined dramatically since the mid-1970s. The biological and climatic patterns suggest that atmospheric warming has raised the average altitude at the base of the orographic cloud bank, as predicted by the lifting-cloud-base hypothesis 9,10 . This hypothesis builds on evidence that rising sea surface temperatures (SSTs) have altered the climates of tropical mountains. Enhanced evaporation from warm ocean surfaces has generated large amounts of water vapour, and latent heat released as this moisture condenses has accelerated atmospheric warming 5 . Because vertical thermal pro®les have tended towards a moist adiabatic lapse rate, the decline in temperature with increasing elevation has diminished, amplifying the warming in the highlands relative to the lowlands 11±13 . Freezing heights have shifted upwards 11 , and glaciers on high tropical mountains are rapidly melting 14 . If temperature-dependent relative humidity surfaces, and thus cloudformation heights, have likewise shifted upwards 10 , organisms may be affected in various ways. Monteverde's stratus±stratocumulus bank, which forms as the trade winds meet the Caribbean slope of the Cordillera de Tilara Ân,¯ow upwards and cool adiabatically, in¯uences several key ecological processes. A lifting cloud base should alter regional hydrology by reducing critical dry-season inputs of mist (low-intensity windblown precipitation) and cloud water (non-precipitating droplets deposited onto vegetation) 15,16 . To examine climate trends, we have analysed patterns of precipitation, stream¯ow, air temperatures and SSTs. The rainfall and air-temperature data (collected by J.H.C.) are from leeward cloud forest (1,540 m; ,1 km west of the Monteverde Cloud Forest Preserve headquarters and ,3 km west of the continental divide). The weather station lies on the western boundary of our 30-ha study plot for anoline lizards, which overlaps a 40-ha plot for birds. Both plots lie within the 30-km 2 anuran study area. The stream-¯ow data (from the Costa Rican Electrical Institute) are for the Rõ Âo Can Äas at Lõ Âbano (300 m; ,23 km northwest of Monteverde). The SST data (from NOAA) are for the Nin Äo-3 region of the equatorial Paci®c (,850 km SW; 1508 W±908 W, 58 N±58 S). Using daily rain-gauge records from the dry season (January± April), we develop a mist-frequency index. These data underestimate windblown inputs 16 but contain signatures of mist events (as well as rare convective showers and wind-driven rains during cold fronts). Because'dry days' (ones without measurable precipitation) represent intervals with little or no mist, their pattern conveys information about the incidence and temporal distribution of mist events. The frequency of dry days is inversely related to mist frequency, so we use the former as a negative index of the latter. letters to nature NATURE | VOL 398 | 15 APRIL 1999 | www.nature.com 611 Figure 1 Trends and¯uctuations in dry-season precipitation and stream¯ow. a, Frequency distributions of daily rainfall by 6-yr periods. b, SSTs (mean anomalies) and dry days in runs $5.

Product flexibility has gained recent attention in companies, which design products for rapidly changing technologies and which are under constant pressure to frequently upgrade their products. In this paper, we develop a method to evaluate product flexibility by performing an empirical study that examines the dependency of flexibility on the number of parts, functions, interfaces, types of interfaces, modules, and the manner of module arrangement. Additionally, a set of guidelines is derived from this study to aid in designing for flexibility.doi:10.1016/j.destud.2004.09.007 fatcat:6vimwsmfcjfobo7psx6dm6jdbu
