    In 1994, a series of human bones was found at the Sidrón cave in Borines (Concejo de Piloña, Asturias), Spain. Since the investigators suspected that they were dealing with human remains from the Spanish Civil War (1936-1939), the bones were collected by the Civil Guard, but were not subjected to archeological scrutiny. The finding was reported then to the corresponding authorities, who had them sent to the Laboratory of Forensic Anthropology of the Forensic Institute of Madrid (Spain), where an anthropological study was undertaken. This revealed the extraordinary palaeoanthropological and palaeopathological interest of the remains. The specimen studied herein, a mandible catalogued as SDR 7-8 (SIDRON 7-8) by the Forensic Laboratory in Madrid (Spain) and belonging to Homo neanderthalensis, with an age of 90,000 to 40,000 years BCE, showed special characteristics of oral pathology, making it a specimen of great palaeodontological interest.Key words: Mandible, Neanderthal, oral pathology, Sidrón, Asturias

    SERS study of thiocarbonyl compounds adsorbed on metal nanoparticles

    Thiocarbonyl compounds have been reported to exhibit interesting biological and pharmacological properties but they are many often characterized by their toxicological effects. However the chemistry of thiobenzoic acid (TBA) and thiobenzamide (TB) has not been fully studied yet. Some of the biological studies of TBA are related to the tautomerism of thiocarboxylic acids and the important role that the -C(=O)-S and -C(=S)-O functional groups play in the catalytic activities of enzymes such as cysteine or serine proteases.1 On the other hand, TB and derivatives are well known hepatotoxins and have been used as inhibitor in enzymatic reactions and in pharmacy due to their microbial activity.2 From a chemical point of view, thiocarboxylates are an interesting type of molecules having two different donor atoms, a soft sulfur donor atom and a hard oxygen donor one. The presence of these unlike groups can lead to the bonding with metal surfaces. Likewise the interaction of thiobenzamide and their derivatives with metals is of great interest because both the sulfur and nitrogen atoms are also able to coordinate with the surface. Therefore the high affinity of these molecules for metal surfaces makes them suitable SERS target adsorbates. Taking advantage of the fact that SERS spectroscopy is both surface selective and highly sensitive we have attempted to determine the molecular structure of TBA and TB once they are adsorbed on the metal. The main objective of this work is focussed on discussing the observed vibrational wavenumber shifts of TBA and TB upon adsorption on silver nanoparticles. In this work the SERS substrates have been prepared by using different colloidal silver solutions according to the method described by Creighton et al.3 and Leopold and Lendl.4 The analysis of the vibrational wavenumbers shifts of the Raman and SERS spectra allow us to know the adsorption process (Figure 1). In the case of TBA, the wavenumber of the SERS band assigned to (C=O) vibrational mode shows an important blue shift up to 40 cm-1 with respect to the Raman whereas the (C-S) band undergoes a red shift up to 40 cm-1. These results suggest a unidentate coordination of TBA to the silver surface through the sulfur atom. On the other hand, the SERS band assigned in the case of TB to Amide III (mainly (CN)) exhibits a significant blueshift up to 41 cm-1, and the SERS band assigned to Amide I (mainly (CS)) shows a red shift up to 11 cm-1. These wavenumber shifts indicate that TB interacts to the silver surface through the sulfur atom. Interestingly, in previous SERS studies of pyridinecarboxamides and benzamide we have observed that some SERS bands assigned to 1;ring, Amide I (mainly (C=O)) and Amide III (mainly C-N)) show wavenumber shifts of +50, -50 and +10 cm-1, respectively, which were attributed to the deprotonation of carboxamide group.5,6 Finally, in order to verify experimental results DFT calculations have been carried out for different silver complexes of TBA and TB concluding that the unidentate coordination is the most likely interaction of both of them.Universidad de Málaga.

    Sleep is a quality-of-life indicator. Sleep alterations have health consequences. The objective of the study was to analyze the sleep pattern in elderly people with metabolic syndrome. A cross-sectional study was carried out on a sample of 326 participants of node 01 of the PREDIMEDPLUS study (University of Malaga). The hours of sleep were quantified objectively with an accelerometer, and subjectively, with a self-reported questionnaire. The average duration of sleep (hours) measured with the accelerometer was higher in women (6.6±0.1) than in men (6.2±0.1); these data differ from self-reported data of 6.7h±0.1 hours in men and 7.3h±0.1 in women. 43% of men and 30% of women sleep less than 6 hours. A high percentage of participants have a poor sleep. In addition, future methodological investigations of sleep assessment are needed.El sueño es un indicador de la calidad de vida.

    Nikodym boundedness property for webs in sigma-algebras

    Full text link
    [EN] A subset B of an algebra A of subsets of Omega is said to have property N if a B-pointwise bounded subset M of ba(A ) is uniformly bounded on A , where ba(A ) is the Banach space of the real (or complex) finitely additive measures of bounded variation defined on A with the norm variation. Moreover B is said to have property sN if for each increasing countable covering (B_m)_m of B there exists B_n which has property N and B is said to have property wN if given the increasing countable coverings (B_m_1 )_m_1 of B and (B_m_1m_2...m_pm_(p+1) )_m_(p+1) of B_m_1m_2...m_p , for each p,m_i &#8712; N, 1<= i <= p + 1, there exists a sequence (n_i )_i such that each B_n_1n_2...n_r , r &#8712; N, has property N. For a &#963;-algebra S of subsets of Omega it has been proved that S has property N (Nikodym Grothendieck), property sN (Valdivia) and property w(sN) (Kakol López-Pellicer). We give a proof of property wN for a &#963;-algebra S which is independent of properties N and sN. This result and the equivalence of properties wN and w2N enable us to give some applications to localization of bounded additive vector measures.This work was supported for the second named author by the Spanish Ministerio de Economía y Competitividad under Grant MTM2014-58159-PLópez Alfonso, S.; Mas Marí, J.; Moll López, SE.

    A cytoplasmic Slo3 isoform is expressed in somatic tissues

    Slo3 is a pH-sensitive and weakly voltage-sensitive potassium channel that is essential for male fertility in mouse and whose expression is regarded as sperm-specific. These properties have proposed Slo3 as a candidate target for male contraceptive drugs. Nonetheless, the tissue distribution of Slo3 expression has not been rigorously studied yet. Applying computational and RT-PCR approaches, we identified expression of two short Slo3 isoforms in somatic mouse tissues such as brain, kidney and eye. These isoforms, which seem to result of transcription starting sites between exons 20 and 21, have an identical open reading frame, both encoding the terminal 381 amino acids of the cytosolic Slo3 domain. We corroborated the expression of these isoforms in mouse brain and testis by Western-blot. The complete isoform encoding the Slo3 ion channel was uniquely detected in testis, both at transcript and protein level. Although the functional role of the cytosolic Slo3 isoforms remains to be established, we propose that they may have a functional effect by modulating Slo channels trafficking and/or activity. This study confirms that expression of full-length Slo3 is sperm-specific but warns against developing contraceptive drugs targeting the C-terminal tail of Slo3 channels

    The impact of age and comorbidity on the postoperative outcomes after emergency surgical management of complicated intra-abdominal infections

    Age-adjusted Charlson Comorbidity Index (a-CCI) score has been used to weight comorbid conditions in predicting adverse outcomes. A retrospective cohort study on adult patients diagnosed with complicated intra-abdominal infections (cIAI) requiring emergency surgery was conducted in order to elucidate the role of age and comorbidity in this scenario. Two main outcomes were evaluated: 90-day severe postoperative complications (grade ≥ 3 of Dindo-Clavien Classification), and 90-day all-cause mortality. 358 patients were analyzed. a-CCI score for each patient was calculated and then divided in two comorbid categories whether they were ≤ or &gt; to percentile 75 (= 4): Grade-A (0–4) and Grade-B (≥ 5). Univariate and multivariate regression analyses were performed, and the predictive validity of the models was evaluated by the area under the receiver operating characteristics (AUROC) curve. Independent predictors of 90-day severe postoperative complications were Charlson Grade-B (Odds Ratio [OR] = 3.49, 95% confidence interval [95%CI]: 1.86–6.52; p &lt; 0.0001), healthcare-related infections (OR = 7.84, 95%CI: 3.99–15.39; p &lt; 0.0001), diffuse peritonitis (OR = 2.64, 95%CI: 1.45–4.80; p &lt; 0.01), and delay of surgery &gt; 24 hours (OR = 2.28, 95%CI: 1.18–4.68; p &lt; 0.02). The AUROC was 0.815 (95%CI: 0.758–0.872). Independent predictors of 90-day mortality were Charlson Grade-B (OR = 8.30, 95%CI: 3.58–19.21; p &lt; 0.0001), healthcare-related infections (OR = 6.38, 95%CI: 2.72–14.95; p &lt; 0.0001), sepsis status (OR = 3.98, 95%CI: 1.04–15.21; p &lt; 0.04) and diffuse peritonitis (OR = 3.06, 95%CI: 1.29–7.27; p &lt; 0.01). The AUROC for mortality was 0.887 (95%CI: 0.83–0.93). Post-hoc sensitivity analyses confirmed that the degree of comorbidity, estimated by using an age-adjusted score, has a critical impact on the postoperative course following emergency surgery for cIAI. Early assessment and management of patient’s comorbidity is mandatory at emergency setting
