The voices and protests of China's labour NGOs and their effort to promote migrant worker rights

Labour NGOs in China are relatively new organizations that emerged in the 1990s and have spread during the 2000s. Migrant workers in China are weak both socially and economically and have been lacking ways of voicing grievances and protesting. Grassroots labour NGOs for migrant workers seem to be an efficient channel for their voices. This paper examines how labour NGOs emerged and how they function in the context of current Chinese society. This paper adopts the case study method to describe three NGOs in Beijing and Shenzhen. The paper shows that these NGOs are using different methods to resolve migrant worker problems. At the same time, they are voicing the migrants' grievances and protesting in their own ways.

La consulta previa en el Perú: avances y retos

El propósito de este trabajo es examinar los esfuerzos realizados y los retos pendientes tras cinco años de implementación del derecho a la consulta previa en el Perú, entre 2011 y mediados del 2016. Este trabajo se divide en tres secciones. La primera ofrece una visión general de los procesos de consulta que se han producido en el Perú hasta diciembre de 2015. La segunda sección examina el papel de los diferentes grupos de interés en relación con este nuevo derecho, mientras que la tercera examina tres casos relacionados directa o indirectamente con las industrias extractivas. El trabajo termina con conclusiones sobre la importancia y los retos de poner en práctica este derecho, y con reflexiones acerca de cómo la elección de un nuevo gobierno en 2016 podría afectar este proceso.

Enantiospecific synthesis of tricyclo5.2.1.0(4,8)]decanes via acid catalysed rearrangement of isotwistanes

An acid catalysed rearrangement was employed for the enantiospecific conversion of isotwistanol to tricyclo5.2.1.0(4.8)]-decanes, which provided support for the proposed biosynthesis of allopupukeananes from pupukeananes. The strategy has been further extended to the enantiospecific synthesis of a homobrexane. (c) 2005 Elsevier Ltd. All rights reserved.

Study of the reaction between 1,2,3-trihydroxybenzene and 8-hydroxyquinoline in the solid state

1.2,3-Trihydroxybenzene (THB) reacts with 8-hydroxyquinoline (8HQ) in the solid state forming an orange-coloured charge transfer complex THB* (8HQ)(2). When the reaction was carried out in a petri dish, or when the vapours of 8HQ were allowed to react with solid THB (gravimetric study), the reaction product separated out as good quality, shiny single crystals. X-Ray diffraction studies on single crystals showed that they belong to the orthorhombic system with a = 15.408(1), b = 16.276(1), c = 7.825(1) Angstrom, Z = 4, D-x = 1.413 g cm(-3) and space group Pnaa. From the crystallographic evidence it has been found that the proton of the middle OH group of THB is transferred to the N atom of 8HQ. This accounts for the observed colour change. Kinetic studies on the solid state reaction showed that the 8HQ molecules diffuse towards THB, and the lateral diffusion occurs through surface migration, grain boundary diffusion and vapour phase diffusion. Gravimetric studies of the reaction between solid THB and 8HQ vapour showed that the diffusion of 8HQ molecules into the crystal lattice of THB has a higher energy of activation than that observed when the reactants are in contact. The nature of the crystal packing in the reaction product indicates diffusion of 8HQ molecules into the crystal lattice of THB along the c-axis, to occupy the cavities present between the THB molecules in the unit cell.

Sequence context analysis of 8.2 million single nucleotide polymorphisms in the human genome

We analyzed n-mers (n=3-8) in the local environment of 8,249,446 human SNPs and compared their distribution with that in the genome reference sequences. The results revealed that the short sequences, which contained at least one CpG dinucleotide, occurred

Chirality in the new generation of antidepressants: stereoselective analysis of the enantiomers of mirtazapine, N-demethylmirtazapine, and 8-hydroxymirtazapine by LC-MS.

Mirtazapine is an antidepressant that acts specifically on noradrenergic and sertonergic receptors. A LC-MS method was developed that allows the simultaneous analysis of the R-(-)- and S-(+)-enantiomers of mirtazapine (MIR), demethylmirtazapine (DMIR), and 8-hydroxymirtazapine (8-OH-MIR) in plasma of MIR-treated patients. The method involves a 3-step liquid-liquid extraction, an HPLC separation on a Chirobiotic V column, and MS detection in electrospray mode. The limit of quantification (LOQ) for all enantiomers was 0.5 ng/mL, and the intra- and interday CVs were within 3.3% to 11.7% (concentration ranges 5-50 ng/mL). A method is also presented for the quantitative analysis of glucuroconjugated MIR and 8-OH-MIR. S-(+)-8-OH-MIR is present in plasma mainly as its glucuronide. Preliminary data suggest that in all patients, except in those comedicated with CYP2D6 inhibitors such as fluoxetine and thioridazine, R-(-)-MIR concentrations were higher than those of S-(+)MIR. Moreover, fluvoxamine seems also to inhibit the metabolism of MIR. Therefore, this method seems to be suitable for the stereoselective assay of MIR and its metabolites in plasma of patients comedicated with MIR and other drugs for routine and research purposes.

Molecular interactions between the penetration enhancer 1,8-cineole and human skin

Penetration enhancers are chemicals that temporarily and reversibly diminish the barrier function of the outermost layer of skin, the stratum corneum, to facilitate drug delivery to and through the tissue. In the current study, the complex mechanisms by which 1,8-cineole, a potent terpene penetration enhancer, disrupts the stratum corneum barrier is investigated using post-mortem skin samples. In order to validate the use of excised tissue for these and related studies, a fibre optical probe coupled to an FT-Raman spectrometer compared spectroscopic information for human skin recorded from in vivo and in vitro sampling arrangements. Spectra from full-thickness (epidermis and dermis) post-mortem skin samples presented to the spectrometer with minimal sample preparation (cold acetone rinse) were compared with the in vivo system (the forearms of human volunteers). No significant differences in the Raman spectra between the in vivo and in vitro samples were observed, endorsing the use of post-mortem or surgical samples for this investigational work. Treating post-mortem samples with the penetration enhancer revealed some unexpected findings: while evidence for enhancer-induced disruption of the barrier lipid packing in the stratum corneum was detected in some samples, spectra from other samples revealed an increase in lipid order on treatment with the permeation promoter. These findings are consistent with phase-separation of the enhancer within the barrier lipid domains as opposed to homogeneous disruption of the lipid lamellae.
