Resumen
A simple method to synthesize carbonaceous porous foams is described, forming simultaneously micropores and macropores, by polymerizing in the external phase of highly concentrated water-in-oil (W/O) emulsions, and pyrolizing the resulting macroporous polymer foam. Highly concentrated W/O emulsions were prepared with 1,1-dichloroethene monomer in the external phase, which was polymerized at low temperature by a redox initiator. Monolithic low-density macroporous foams were obtained after polymerization and purification by soxhlet extraction. These foams were mainly macroporous, with low surface area (?28 m2 g-1) and negligible microporosity and mesoporosity, as expected. The size (2-10 ?m) and morphology of the macropores were consistent with the droplet size (2-10 ?m) and shape (polyhedral) of the highly concentrated W/O emulsions. Pyrolization of the macroporous polymer foams allowed the formation of micropores while the macroporous texture was preserved, and consequently, dual micro/macroporous carbonaceous monoliths were obtained, with a large surface area (>800 m 2 g-1). These materials were characterized by optical microscopy, scanning and transmission electron microscopy, N2 sorption isotherms, infrared absorption spectroscopy and elemental analysis. The influence of pyrolysis temperature (300, 400 and 500 C) was studied. " 2013 Elsevier Inc.

The exchanges (1;19) and (12;21) were ascertained through a balanced carrier, whereas the t(9;13) was first diagnosed in a boy with a trisomy 9p syndrome and der(9p13p). Results of FISH analyses with the appropriate ?-satellite probes were as follows. Family 1, t(1;19): the D1Z5 probe gave a strong signal on both the normal chromosome 1 and the der(1q19p) as well as a weak signal on the der(1p19q). Family 2, t(9;13): the centromere-9 alphoid and D13Z1/D21Z1 probes under standard stringency gave no signal on the der(9p13p) in both the proband and a carrier brother, whereas the der(9q13q) was labelled only with the centromere-9 alphoid repeat in the latter; yet, this probe under low stringency revealed a residual amount of alphoid DNA on the der(9p13p) in the carrier. Family 3, t(12;21): the D12Z3 probe gave a signal on the normal chromosome 12 and the der(12p21q), whereas the D13Z1/D21Z1 repeat labelled the der(12q21p), the normal chromosome 21, and both chromosomes 13. Out of 101 WATs compiled here, 73 are distinct exchanges, including 32 instances between chromosomes with common alphoid repeats. Moreover, 7/9 of recurrent WATs involved chromosomes from the same alphoid family. Thus constitutional WATs appear to recur more frequently than other reciprocal exchanges, often involve chromosomes with common alphoid repeats, and can mostly be accounted for the great homology in alphoid DNA that favours mispairing and illegitimate nonhomologous recombination.",,,,,,,,,"http://hdl.handle.net/20.500.12104/41447","http://www.scopus.com/inward/record.url?eid=2-s2.0-34548269996&partnerID=40&md5=c307c0d74a5c7a0bce3a4e1d150abad6 http://ovidsp.ovid.com/ovidweb.cgi?T=JS&CSC=Y&NEWS=N&PAGE=fulltext&D=med5&AN=17666779",,,,,,"3",,"Journal of Applied Genetics",,"261 268",,"48",,"Scopus MEDLINE WOS",,,,"Index Medicus;Abnormalities, Multiple/ge [Genetics];Abnormalities, Multiple/pa [Pathology];Adolescent;Centromere;Child;Chromosomes, Human, Pair 1/ge [Genetics];Chromosomes, Human, Pair 12/ge [Genetics];Chromosomes, Human, Pair 13/ge [Genetics];Chromosomes, Human, Pair 19/ge [Genetics];Chromosomes, Human, Pair 21/ge [Genetics];Chromosomes, Human, Pair 9/ge [Genetics];Craniosynostoses/ge [Genetics];Craniosynostoses/pa [Pathology];Family;Female;Humans;In Situ Hybridization, Fluorescence;Karyotyping;Male;Phenotype;Recombination, Genetic;Repetitive Sequences, Nucleic Acid;Translocation, Genetic;Trisomy",,"Alphoid DNA; Human chromosomes; translocation (1;19); Translocation (12;21); Translocation (9;13); Whole-arm exchange",,,,,,"Familial whole-arm translocations (1;19), (9;13), and (12;21): A review of 101 constitutional exchanges",,"Article"

However, Hispanics with RA develop high rates of coronary disease; there are no studies about the frequency and factors related to high levels of homocysteine in Mexican patients. Objective: To evaluate the prevalence and characteristics associated with hyperhomocysteinaemia in Mexican patients with RA. Methods: One hundred and fifty-two patients with RA were compared with 153 controls. The assessment in RA included clinical characteristics, disease activity (RADAR), functioning (HAQ-Di and global functional status), comorbidity, and radiological damage. Laboratory determinations included total serum homocysteine (tHcy), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), and lipid profile. Results: Median levels of homocysteine were higher in RA compared with controls (11.3 vs. 9.3, p < 0.001). Twenty per cent of the patients with RA had hyperhomocysteinaemia (> 15 ?mol/L) compared with 6% in controls (p < 0.001). There was statistical association between hyperhomocysteinaemia in RA with male gender (p < 0.001), impairment in the global functional status (p=0.004), higher radiological damage (p=0.001), and CRP (p=0.04). There was no association with RADAR, HAQ-Di, or RF, methotrexate dose or duration of use. In the adjusted multivariate model, the two variables associated with higher risk for hyperhomocysteinaemia were male gender (OR=4.2, 95% CI 2 to 12, p=0.006) and higher radiological damage (III-IV) (OR=3.4, 95% CI 1.3 to 9, p=0.01). Conclusions: Our data show a high prevalence of hyperhomocysteinaemia in Mexican patients with RA. More effort is required to evaluate and treat earlier this coronary risk factor.
