Introduction
The work of Bion, developing the psychoanalytic theories of Freud and Klein on the origins of anxiety in childhood, includes the hypothesis of a protomental system as a matrix in the human organism in which physical and mental are at first undifferentiated. He defends that the continuing experience by the infant of parental containment of its anxieties, through a process of projection and introjection, develops its capacity for thinking about frustration rather than evading it. This conception was extended to psychosomatic illness, by the hypothesis that, without this experience, frustration may lead to basic assumption mentality and psychosomatic illness rather than emotions and thought.
ObjectivesThis work aims to describe an experimental technique of group psychotherapy, inspired in Bion's principles combined with relaxation techniques, in the context of psychosomatic diseases.
AimsThe authors pretend to identify improvement in clinical symptomatology, quality of life, identification and expression of emotions, in the group submitted to this method, compared to controls.
MethodsIt was performed a weekly group psychotherapeutic session and a weekly relaxation session (using Jacobson's method), along two months. The patients were randomly selected and submitted to psychological evaluation with scales and questionnaires, in the beginning and at the end of the study.
ResultsAt the time of submission of this work, the results of the intervention were in analysis.
ConclusionsThis paper describes an experimental method of psychotherapeutic intervention in the field of psychosomatic disease, using a transdisciplinary perspective.

Introduction
Sleep paralysis (SP) is relatively frequent condition, occurring either at sleep onset or sleep offset. It occurs at least once in a lifetime in 40–50% of normal subjects. During SP, the patient experiences gross motor paralysis, while the sensory system is clear. Hypnogogic and hypnopompic hallucinations are common. This experience might be interpreted as a spiritual phenomenon in several cultures, each one with different interpretations and attributions.
ObjectiveThe authors revisit the clinical presentation of sleep paralysis and how this sleep disorder is seen from a cultural perspective.
AimsTo describe several cultural interpretations of SP.
MethodsA literature review of the theme is shortly surveyed.
ResultsIt is very common during an episode of SP sensing the presence of menacing intruders in one's bedroom. Supernatural accounts of this hallucinated intruder are common across cultures. It has been traditionally labeled “ghost oppression” among the Chinese. In the Abruzzo region (Italy), the supernatural interpretation of the phenomena is called the Pandafeche attack. One study found that nearly half (48%) of the participants from the general Egyptian population believed their SP to be caused by the Jinn, a spirit-like creature. In Southwest Nigeria, Ogun Oru is a traditional explanation for nocturnal neuropsychiatric disturbances. The characteristics of the ‘a dead body climbed on top of me’ phenomenon suggest that is identical to sleep paralysis and a frequent experience among Mexican adolescents.
ConclusionsDepending on the etiological interpretations of SP, which is largely culturally determined, patients react to the event in specific ways.

The BW has been largely used as a selection criterion in genetic selection programmes; however, increases in BW can affect animal metabolism and metabolites. The knowledge of how genetic potential for growth affects the metabolites can give a footprint of growth metabolism. This research aimed to evaluate the effect of genetic potential for post-weaning growth (GG) on performance, carcass traits and serum metabolome of non-castrated Nellore males during the finishing phase. Forty-eight Nellore non-castrated males, with divergent potential for post-weaning growth, were selected and divided into two groups: high potential for post-weaning growth (HG; n = 24) and low potential for post-weaning growth (LG; n = 24). Animals were kept and fed for 90 days where performance and ultrasound carcass traits were evaluated. Blood samples were collected at the beginning and end of feeding period to analyse serum metabolites concentration. The hot carcass weight and dressing percentage were recorded at slaughter. The feedlot performance and carcass traits were not affected by genetic potential. The HG animals had a lower glucose (P = 0.039), glutamate (P = 0.038), glutamine (P = 0.004), greater betaine (P = 0.039) and pyruvate (P = 0.039) compared to the LG group at the beginning of feedlot. In addition, higher creatine phosphate concentrations were observed at the beginning of feeding period, compared to final, for both groups (P = 0.039). In conclusion, the genetic potential for post-weaning growth does not affect performance and carcass traits during the finishing period. Differences in metabolite concentrations can be better found at the beginning of feedlot, providing a footprint of growth metabolism, but similar metabolite concentration at the end of finishing period.

Bendadaite, ideally Fe2+Fe23+ (AsO4)2(OH)2·4H2O, is a new member of the arthurite group. It was found as a weathering product of arsenopyrite on a single hand specimen from the phosphate pegmatite Bendada, central Portugal (type locality). Co-type locality is the granite pegmatite of Lavra do Almerindo (Almerindo mine), Linópolis, Divino das Laranjeiras county, Minas Gerais, Brazil. Further localities are the Veta Negra mine, Copiapó province, Chile; Oumlil-East, Bou Azzer district, Morocco; and Pira Inferida yard, Fenugu Sibiri mine, Gonnosfanadiga, Medio Campidano Province, Sardinia, Italy.
Type bendadaite occurs as blackish green to dark brownish tufts (<0.1 mm long) and flattened radiating aggregates, in intimate association with an intermediate member of the scorodite–mansfieldite series. It is monoclinic, space group P21/c, with a = 10.239(3) Å, b = 9.713(2) Å, c = 5.552(2) Å, β = 94.11(2)°, V = 550.7(2) Å3, Z = 2. Electron-microprobe analysis yielded (wt.%): CaO 0.04, MnO 0.03, CuO 0.06, ZnO 0.04, Fe2O3 (total) 43.92, Al2O3 1.15, SnO2 0.10, As2O5 43.27, P2O5 1.86, SO3 0.03. The empirical formula is (Fe2+0.52Fe3+0.32☐0.16)Σ1.00(Fe3+1.89Al0.11)Σ2.00(As1.87P0.13)Σ2.00O8(OH)2.00·4H2O based on 2(As,P) and assuming ideal 8O, 2(OH), 4H2O and complete occupancy of the ferric iron site by Fe3+ and Al. Optically, bendadaite is biaxial, positive, 2Vest. = 85±4°, 2Vcalc. = 88°, with α 1.734(3), β 1.759(3), γ 1.787(4). Pleochroism is medium strong: X pale reddish brown, Y yellowish brown, Z dark yellowish brown; absorption Z > Y > X, optical dispersion weak, r > v. Optical axis plane is parallel to (010), with X approximately parallel to a and Z nearly parallel to c. Bendadaite has vitreous to sub-adamantine luster, is translucent and non-fluorescent. It is brittle, shows irregular fracture and a good cleavage parallel to {010}. Dmeas. 3.15±0.10 g/cm3, Dcalc. 3.193 g/cm3 (for the empirical formula). The five strongest powder diffraction lines [d in Å (I)(hkl)] are 10.22 (10)(100), 7.036 (8)(110), 4.250 (5)(111), 2.865 (4)(), 4.833 (3)(020,011). The d spacings are very similar to those of its Zn analogue, ojuelaite. The crystal structure of bendadaite was solved and refined using a crystal from the co-type locality with the composition (Fe2+0.95☐0.05)Σ1.00(Fe3+1.80Al0.20)Σ2.00(As1.48P0.52)Σ2.00O8(OH)2·4H2O (R = 1.6%), and confirms an arthurite-type atomic arrangement.
