TL;DR: Developmental series strongly suggest that the so-called epibranchial 5 of actinopterygians does not belong to the epal series because it shares the same chondroblastic layer with ceratobranchial 4 and its ontogenetic emergence is considerably late.
Abstract: Epibranchials are among the main dorsal elements of the gill basket in jawed vertebrates (Gnathostomata). Among extant fishes, chondrichthyans most resemble the putative ancestral condition as all branchial arches possess every serially homologous piece. In osteichthyans, a primitive rod-like epibranchial 5, articulated to ceratobranchial 5, is absent. Instead, epibranchial 5 of many actinopterygians is here identified as an accessory element attached to ceratobranchial 4. Differences in shape and attachment of epibranchial 5 in chondrichthyans and actinopterygians raised suspicions about their homology, prompting us to conduct a detailed study of the morphology and development of the branchial basket of three ostariophysans (Prochilodus argenteus, Characiformes; Lophiosilurus alexandri and Pseudoplatystoma corruscans, Siluriformes). Results were interpreted within a phylogenetic context of major gnathostome lineages. Developmental series strongly suggest that the so-called epibranchial 5 of actinopterygians does not belong to the epal series because it shares the same chondroblastic layer with ceratobranchial 4 and its ontogenetic emergence is considerably late. This neomorphic structure is called accessory element of ceratobranchial 4. Its distribution among gnathostomes indicates it is a teleost synapomorphy, occurring homoplastically in Polypteriformes, whereas the loss of the true epibranchial 5 is an osteichthyan synapomorphy. The origin of the accessory element of ceratobranchial 4 appears to have occurred twice in osteichthyans, but it may have a single origin; in this case, the accessory element of ceratobranchial 4 would represent a remnant of a series of elements distally attached to ceratobranchials 1–4, a condition totally or partially retained in basal actinopterygians. Situations wherein a structure is lost while a similar neomorphic element is present may lead to erroneous homology assessments; these can be avoided by detailed morphological and ontogenetic investigations interpreted in the light of well-supported phylogenetic hypotheses.

TL;DR: The aim of this study was to evaluate the prevalence of dysphoria/depressive symptoms in mothers of autistic children and to identify correlations between quality of life and socio-demographic profile and further research, especially on those variables that were not statistically relevant, is suggested.
Abstract: The aim of this study was to evaluate the prevalence of dysphoria/depressive symptoms in mothers of autistic children and to identify correlations between quality of life and socio-demographic profile. An exploratory, descriptive and cross-sectional study was carried out, involving 20 mothers, by applying a socio-demographic profile questionnaire, the Brazilian version of the Beck Depression Inventory (BDI) and the WHOQOL-Bref quality of life scale. Dysphoria/depression criteria were found in 15% of the mothers. Overall quality of life was evaluated as positive in 70%, however only 40% were satisfied with their health. The Physical domain (mean=69.4) was perceived as the best, and environment domain as the worst (mean=60.8). Quality of life had a positive association with family income and level of education, and a negative association with depression. Considering the results, further research, especially on those variables that were not statistically relevant, is suggested.

TL;DR: This study investigates how collagen into biomimetic matrixes affects hydroxyapatite (HAp) growth by inserting collagen into insoluble Langmuir monolayers containing either 1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC) or octadecylphosphonic acid (OPA) and transferring to titanium supports by means of the LangmuIR-Blodgett (LB) technique.
