The dispersal of Crocodylus from Africa to Europe during the Miocene is not well understood. A small collection of cranial fragments and postcranial elements from the latest Miocene (6.2 Ma) site of Venta del Moro (Valencia, Spain) have previously been referred to Crocodylus cf. C. checchiai Maccagno, 1947 without accompanying descriptions. Here we describe and figure for the first time the crocodylian remains from Venta del Moro, which represent at least two individuals. Our comparisons indicate that this material clearly does not belong to Diplocynodon or Tomistoma—the only two other crocodylians described so far for the European late Miocene. The material is only tentatively referred to cf. Crocodylus sp. because the apomorphies of this genus are not preserved and a referral to C. checchiai cannot be supported on a morphological basis. However, it is likely that this late Miocene species, originally described from Libya (As Sahabi) and later identified also in Kenya, could have dispersed across the Mediterranean Basin multiple times and colonized the southern areas of Mediterranean Europe, as evidenced by several Crocodylus or Crocodylus-like remains described during the past years.

The usual emotional experience of the person (affective style) is an influential factor in therapeutic assimilation. Based on a dynamic model of affect shaped dimensionally by the valence and arousal axes (core affect) that fluctuate over time according to the specific context of the individual, its relationship with different variables was investigated and the changes after a 6-month intervention in a specialized hospital unit (N = 103) were observed. The orthogonal structure of core-affect was confirmed. Emotional valence appeared to be positively related to social skills (r = .375; p < .01) and self-esteem (r = .491; p < .01) and negatively to depressive symptoms (r = –.631; p < .01), general disturbance (r = –.395; p < .01) and suicidality (r = –.490; p < .01). Emotional arousal is associated with impulsivity (r = .345; p < .01). The group of patients with an affective style characterized by negative valence and low arousal core-affect gained less therapeutic benefit compared to those with positive valence core-affect (p < .05). Throughout the treatment, valence became more positive (d = .26; IC 95%: 1.9 – 7.2; p = .001), arousal increased (d = .23; IC 95%: 0.2 – 1.7; p = .015) and variability decreased (d = –.44; IC 95%: (–2.9) – (–1.1); p = .001). Changes in the core-affect are related to therapeutic improvement. Adjusting expectations of change can reduce therapeutic frustration, which is as common as it is harmful in the treatment of severe personality disorders.

The Meta-cognitions Questionnaire 30 (MCQ-30; Wells & Cartwright-Hatton, 2004) has been used to assess individual differences in metacognitive beliefs considered to be central in the metacognitive theory of generalized anxiety disorder (Wells, 2005). In the present study, the psychometric properties, reliability, and validity of a Spanish adaptation of the MCQ-30 were tested in a broad sample of participants (N = 768) of Spanish nationality aged 16–81 years (31.1% males, 68.9% females). Confirmatory factor analysis showed the expected five-factor structure, which was found to be invariant across gender. Internal consistency and test-retest reliability of the subscales were adequate, and the expected relationships to theoretically related variables such as pathological worry, meta-worry, thought suppression and trait anxiety were obtained. Convergent validity with other measures of beliefs about worry was also found. Taken together, these findings suggest that the Spanish version of the MCQ-30 is a valid instrument for evaluating metacognitive beliefs in the Spanish-speaking population.

Background: Dementia is becoming a major public health problem in Latin America (LA), yet epidemiological information on dementia remains scarce in this region. This study analyzes data from epidemiological studies on the prevalence of dementia in LA and compares the prevalence of dementia and its causes across countries in LA and attempts to clarify differences from those of developed regions of the world.
Methods: A database search for population studies on rates of dementia in LA was performed. Abstracts were also included in the search. Authors of the publications were invited to participate in this collaborative study by sharing missing or more recent data analysis with the group.
Results: Eight studies from six countries were included. The global prevalence of dementia in the elderly (≥65 years) was 7.1% (95% CI: 6.8–7.4), mirroring the rates of developed countries. However, prevalence in relatively young subjects (65–69 years) was higher in LA studies The rate of illiteracy among the elderly was 9.3% and the prevalence of dementia in illiterates was two times higher than in literates. Alzheimer's disease was the most common cause of dementia.
Conclusions: Compared with studies from developed countries, the global prevalence of dementia in LA proved similar, although a higher prevalence of dementia in relatively young subjects was evidenced, which may be related to the association between low educational level and lower cognitive reserve, causing earlier emergence of clinical signs of dementia in the LA elderly population.

A study was carried out to analyse the production and composition of milk from Malagueña goats of different genotypes for the content of αs1-casein. Twenty goats were used, half of them with a high (HG) and half with a low (LG) genetic capability for αs1-casein synthesis. Among the ten HG goats, seven had BB and three had AB genotypes, whereas there were seven EF and three FF genotypes among the LG goats. The goats were fed a diet differing in crude protein content, 136 and 177 g/kg dry matter for diet 1 (D1) and diet 2 (D2), respectively. For each genotype group, a trial was conducted, with each of the two diets in a two-period balanced change-over design, in which the milk production and composition were analysed. The genotype was found to determine milk composition, with that produced by the HG goats being higher in total solids, protein, αs1-casein, αs2-casein and fat. Analysis of milk production values and, especially, those of the yields of the different components, revealed an interaction between the factors. HG goats that consumed D1 were more productive than LG goats, but this ceased to be so when the D1 diet was replaced by D2. However, LG goats, although less productive than HG ones when the D1 diet was consumed, showed increased productive capacity when D1 was replaced by D2. The main difference for the fatty acid profile of the dairy fat is that the milk fat produced by the HG goats contained higher levels of short and medium-chain fatty acids. From these results, it is concluded that, in terms of favouring production, the advantage of replacing animals with a low capacity for αs1-casein synthesis with those of a high capacity seems to depend on the protein level in the diet. Similarly, the advantage of changing to a diet of higher protein content depended on the animal's genotype.

Benzyladenine, a synthetic cytokinin, stimulates DNA metabolism during maize germination; apparently such stimulation occurs in two phases, and during the first phase stimulations of DNA synthesis, of protein kinase activity (both α-amanitin repressible), of DNA polymerase and poly ADP-ribosyl polymerase activities are observed. Since the evidence suggested that the effects produced by BA were due, at least partially, to transcriptional activation, attempts were made to discover genes, by subtractive hybridization of a cDNA library or by differential display, whose expression depended on the presence of BA; however these were unsuccessful. BA modulated the expression of a limited number of genes only. The possible mechanism by which BA could be promoting DNA metabolism during maize germination is discussed.

The effect of natural and artificial seed ageing has been compared in terms of physiological and biochemical responses of several maize genotypes. The physiological parameters were: viability, germinability, emergence in sand and dry matter accumulation. The biochemical parameters were: DNA synthesis and DNA polymerase activity. A close and direct relationship was found between seed deterioration and DNA metabolism in all maize materials which responded to ageing according to their genetic constitution; i.e., vigorous genotypes suffered less severe damage or recovery was faster than in the low-vigour genotypes. Coordination of events at appropriate times would seem a critical factor for proper seed germination.

The search for germination-specific genes has been a laborious and unrewarding task, since many of the genes expressed during germination are also expressed in embryogenesis or in other developmental stages. By using mRNA differential display of transcript populations from maize (Zea mays L.) embryo axes, germinated for different times with or without a previous osmopriming treatment, a 682 bp cDNA was isolated that was present only after 24 h germination, and absent during osmopriming or during early germination. Screening of a cDNA library using the 682 bp probe yielded a 1554 bp cDNA that contained an open reading frame coding for 436 amino acids. This gene, referred to as ZmAA9-24, was expressed in root tissues, but was not detected in shoot or leaf tissues. Expression of ZmAA9-24 occurred earlier during germination (by 15 h) if embryo axes were imbibed in the presence of cytokinins or if seeds were previously osmoprimed. The predicted protein sequence of ZmAA9-24 is 39.6% identical to the product of the recently identified Arabidopsis gene COBRA (54.5% in the central region), which appears to participate in the regulation of cell expansion, particularly in roots, and belongs to the glycosylphosphatidylinositol (GPI)-anchored protein family. ZmAA9-24 expression might be regulated by both cell expansion and the cell cycle, processes that have a central role during seed germination.

Objective: To evaluate the potential contribution of “extrinsic” contamination of intravenous fluids in hospital bacteremia and infection.
Design: Prospective cross-sectional survey of infusate contamination, December 1992 to December 1993.
Setting: A pediatric department (1,500 admissions per year) in a general, urban teaching hospital, serving low-income patients.
Samples and Patients: Infusate samples (0.5 to 1.0 mL) from the injection port used by the staff were taken for cultures from all febrile or septic patients in hospital wards. At least four samples were taken each day; if no febrile or septic patients were available, other patients were sampled at convenience.
Results: A 6.8% positive culture rate (87 contaminates in 1,277 infusates) was obtained, without significant differences among the wards. Gram-negative organisms were recovered from 56 samples (62.9%), mainly of the tribe Klebsielleae (56.1%). Coagulase-negative staphylococci were isolated in 30 samples (33.7%). There was no significant difference between the febrile-septic group and the asymptomatic group in the rate of infusate contamination (P=.59). In eight patients, the same organisms were recovered from infusate and blood culture. The overall bacteremia rate was 2.5 per 100 discharges.
Conclusions: Compared to previous reports, higher infusate contamination rates and different organisms (mainly gram-negative) were observed. In hospitals of underdeveloped countries, nosocomial infection control frequently is disregarded. Infusate contamination may be common and could lead to gram-negative bacteremia. In such settings, it seems advisable to perform surveillance studies to identify infusate contamination, because a single infusate contamination could be a signal for an epidemic.
