A comparison of the moss floras of Chile and New Zealand
No full textChile and New Zealand share a common stock of 181 species of mosses in 94 genera and 34 families. This number counts for 23.3% of the Chilean and 34.6% of the New Zealand moss flora. If only species with austral distribution are taken into account, the number is reduced to 113 species in common, which is 14.5% of the Chilean and 21.6% of the New Zealand moss flora. This correlation is interpreted in terms of long distance dispersal resp. the common phytogeographical background of both countries as parts of the palaoaustral floristic region and compared with disjunct moss floras of other continents as well as the presently available molecular data

Mesograzer interactions with a unique strain of Irish moss Chondrus crispus: colonization, feeding, and algal condition-related effects
No full textMarine macroalgae are exposed to multiple sources of stress. As a result, perennial macroalga habitats have become depleted in many coastlines. Here, we investigated the role of mesograzers in the sharp decline of a unique strain of Chondrus crispus (the giant Irish moss) found solely in a lagoon in Atlantic Canada. This study was prompted by damage resembling grazing scars that appeared on the fronds as the population declined, for which no grazer had been identified. We identified potential grazers of the seaweed by deploying 4 types of experimental clumps of giant Irish moss and sampling the epifauna that colonized them. Laboratory assays were then run with an abundant species, the amphipod Gammarus oceanicus, to measure feeding rates and test whether this mesograzer is capable of consuming the alga and creating measurable damage. G. oceanicus readily consumed the Irish moss at a grazing rate of 5.24 mg amphipod-1 d-1 and created deep lateral grazing wounds similar to those observed in the field. An additional experiment was conducted to assess whether a co-acting stressor in the lagoon, the accumulation of fine sediments, could explain the appearance and spatially patchy distribution of the damage in the population. Giant Irish moss fronds that had been buried under sediment lost twice as much biomass as those that had not. These results suggest that grazer activity and declining conditions in the lagoon have a negative and additive effect on this unique strain of Irish moss, with clear implications for its restoration

Psychosocial interventions for adults with visible differences: a systematic review
No full textBackground. Some individuals with visible differences have been found to experience psychosocial adjustment problems that can lead to social anxiety and isolation. Various models of psychosocial intervention have been used to reduce social anxiety and appearance related distress in this population. The objective of this review was to update a previous systematic review assessing the efficacy of psychosocial intervention programs for adults with visible differences. The original review (Bessell & Moss, 2007) identified 12 papers for inclusion.Methods. A search protocol identified studies from 13 electronic journal databases. Methods: Studies were selected in accordance with pre-set inclusion criteria and relevant data were extracted.Results. This update identified an additional four papers that met the inclusion criteria. Two papers provided very limited evidence for the efficacy of a combined cognitive-behavioural and social skills training approach. None of the papers provided sufficient evidence for the optimal duration, intensity or setting of psychosocial interventions for this population.Discussion. The review concluded that a greater number of Randomised Controlled Trials and experimental studies were required to increase the methodological validity of intervention studies
Maternal betamethasone administration reduces binucleate cell number and placental lactogen in sheep
No full textThe placenta may mediate glucocorticoid-induced fetal growth restriction. Previous studies have examined effects of fetal cortisol in sheep, which reduces placental binucleate cell (BNC) number; the source of ovine placental lactogen (oPL). The effects of maternal GC are unknown. Therefore, this study examined the effects of maternal betamethasone (BET) administration on BNC number, distribution, placental oPL protein levels, and maternal and fetal plasma oPL levels. Pregnant ewes were randomized to receive injections of saline or one (104 days of gestation; dG), two (104 and 111 dG), or three (104, 111, and 118 dG) doses of BET (0.5 mg/kg). Placental tissue was collected before, during, and after the period of BET treatment. Fetal (121-146 dG) and placental (121 dG) weights were decreased after BET when compared with controls. In controls, the mean number of BNCs increased until 132 dG and decreased thereafter. Placental oPL protein levels peaked at 109 dG and remained stable thereafter. Maternal plasma oPL levels in controls increased across gestation; fetal plasma oPL levels decreased. BNCs were reduced by 24% to 47% after BET when compared with controls at all ages studied. Placental oPL protein levels, maternal, and fetal plasma oPL levels were also reduced after BET injections, but recovered to values that were not different to controls near term. BET disrupted the normal distribution of BNCs within the placentome. These data may suggest a placental role in growth restrictive effects of prenatal maternal BET exposure through alterations in placental output of oPL, a key metabolic hormone of pregnancy
The taxonomic status of Bryum arachnoideum C. Müll. and B. lanatum (P. Beauv.) Brid.
No full textA study of an isotype of Bryum arachnoideum C. Müll., a poorly understood species described from tropical Africa, revealed that this species is distinct from B. argenteum Hedw. var. lanatum (P. Beauv.) Hampe. The differences between both species are listed. All specimens from tropical Africa named as B. arachnoideum by the author must be attributed to B. argenteum var. lanatum. The differences between B. argenteum var. argenteum and var. lanatum, both morphologically and ecologically, are so important that it is proposed to treat var. lanatum on a species level as B. lanatum (P. Beauv.) Brid

Psychological impact of visible differences in patients with congenital craniofacial anomalies
No full text© 2015, Singh and Moss; licensee Springer. Background: Patients with craniofacial anomalies often have appearance concerns and related social anxiety which can affect their quality of life. This study assessed the psychological impact of facial and dental appearance in patients with craniofacial anomalies in comparison to a general population control group. Methods: The study involved 102 adult patients (51% male) with congenital craniofacial anomalies and 102 controls (49% male). Both groups completed the Nepali version of Derriford Appearance Scale (DAS) and the Psychological Impact of Dental Aesthetic Questionnaire (PIDAQ) in a clinical setting to assess appearance-related distress, avoidance, and anxiety. Results: There was a significant difference between patients and controls on both PIDAQ (mean score for patients 33.25 ± 9.45 while for controls 27.52 ± 5.67, p < 0.001) and DAS59 scores (mean score for patients 159.16 ± 31.54 while for controls 77.64 ± 6.57, p < 0.001), indicating that patients experienced greater negative psychological impact of living with their appearance (PIDAQ) and more appearance-related distress (DAS) than controls. DAS scores were not associated with gender. There was no association of the place of residence (rural vs. urban) with PIDAQ or DAS59 scores. Conclusions: There is a significant psychological impact of altered facial and dental appearance in patients with craniofacial anomalies compared to controls. There was no effect of locality (rural/urban) on the psychological impact of facial and dental appearance in patients
