Ethical consumers and ethical trade: a review of current literature (NRI Policy Series 12)
This publication reviews the large number of consumer surveys of ethical consumerism, and describes the different types of ethical consumer, their motivation and concerns, their willingness to pay an ethical premium, and the ways they learn about ethical products. It shows how different survey methodologies affect what we know and do not know about ethical consumerism, and highlights how methodological shortcomings are starting to be addressed.The publication reveals that ethical consumerism is a complex phenomenon, something that those calling for greater consumer awareness of ethical issues need to understand when promoting different forms of ethical trade. The fair-trade and organic movements have been at the forefront of understanding this phenomenon, and their experiences offer lessons for the commercial mainstream, particularly the importance of information and awareness as a prerequisite for action. These lessons are also crucial for international development agencies that need to understand the operation of Northern markets if their investment in ethical approaches to trade in developing countries is to pay dividends

The Procedure of Termination of the Criminal Case (Criminal Prosecution) on Rehabilitation Bases in the Russian Federation and Mongolia
The article describes the features of the modern criminal procedure of Mongolia, which consist in the absence of the stage of initiation of criminal proceedings, confluence of a decision of initiation of criminal proceedings and decision about prosecution as an accused, in existence of uniform termination procedure of investigation of the criminal cases subject to termination or referral to court. Comparative legal analysis of rehabilitating grounds for termination of criminal case (criminal prosecution) is carried out. The content of criminal procedural activities at the end of the investigation is considered. The procedure for appealing against decisions on termination of the criminal case is researched. It is characterized by a lack of judicial control in pre-trial proceedings in Mongolia. The procedure and law enforcement practice of realization of the right to rehabilitation is analyzed. The conclusion that departmental regulation hinders its implementation is made. The Authors state that the procedure for termination of the criminal case provided by the Criminal procedure code of Mongolia contains fairly extended guarantees of establishing the truth. The normative regulation completely excludes multiple transfer of the criminal case from the police to prosecutor in the event of discrepancy in the assessment of the qualification of the crime and the completeness of the investigation. The absence of a procedure for the termination of criminal prosecution due to non-involvement is a serious drawback of Mongolian legislation. In general, the mechanism of termination of the criminal case in the criminal procedure legislation of Mongolia is conceptually more consistent and logical, but in terms of elaboration of procedural mechanisms is much inferior to Russian legislation
Tumor detection and elimination by a targeted gallium corrole
Sulfonated gallium(III) corroles are intensely fluorescent macrocyclic compounds that spontaneously assemble with carrier proteins to undergo cell entry. We report in vivo imaging and therapeutic efficacy of a tumor-targeted corrole noncovalently assembled with a heregulin-modified protein directed at the human epidermal growth factor receptor (HER). Systemic delivery of this protein-corrole complex results in tumor accumulation, which can be visualized in vivo owing to intensely red corrole fluorescence. Targeted delivery in vivo leads to tumor cell death while normal tissue is spared. These findings contrast with the effects of doxorubicin, which can elicit cardiac damage during therapy and required direct intratumoral injection to yield similar levels of tumor shrinkage compared with the systemically delivered corrole. The targeted complex ablated tumors at >5 times a lower dose than untargeted systemic doxorubicin, and the corrole did not damage heart tissue. Complexes remained intact in serum and the carrier protein elicited no detectable immunogenicity. The sulfonated gallium(III) corrole functions both for tumor detection and intervention with safety and targeting advantages over standard chemotherapeutic agents

Activated Bone Marrow-Derived Macrophages Eradicate Alzheimer's-Related Aβ42 Oligomers and Protect Synapses.
Impaired synaptic integrity and function due to accumulation of amyloid β-protein (Aβ42) oligomers is thought to be a major contributor to cognitive decline in Alzheimer's disease (AD). However, the exact role of Aβ42 oligomers in synaptotoxicity and the ability of peripheral innate immune cells to rescue synapses remain poorly understood due to the metastable nature of oligomers. Here, we utilized photo-induced cross-linking to stabilize pure oligomers and study their effects vs. fibrils on synapses and protection by Aβ-phagocytic macrophages. We found that cortical neurons were more susceptible to Aβ42 oligomers than fibrils, triggering additional neuritic arborization retraction, functional alterations (hyperactivity and spike waveform), and loss of VGluT1- and PSD95-excitatory synapses. Co-culturing neurons with bone marrow-derived macrophages protected synapses against Aβ42 fibrils; moreover, immune activation with glatiramer acetate (GA) conferred further protection against oligomers. Mechanisms involved increased Aβ42 removal by macrophages, amplified by GA stimulation: fibrils were largely cleared through intracellular CD36/EEA1+-early endosomal proteolysis, while oligomers were primarily removed via extracellular/MMP-9 enzymatic degradation. In vivo studies in GA-immunized or CD115+-monocyte-grafted APPSWE/PS1ΔE9-transgenic mice followed by pre- and postsynaptic analyses of entorhinal cortex and hippocampal substructures corroborated our in vitro findings of macrophage-mediated synaptic preservation. Together, our data demonstrate that activated macrophages effectively clear Aβ42 oligomers and rescue VGluT1/PSD95 synapses, providing rationale for harnessing macrophages to treat AD
A study on structure and functions of organs involved in the formation of Mongolian Khuumii sound
Khuumii (throat or overtone singing) is a unique form of art derived from the nomadic population of Central Asia, which is a type of singing in which the singer manipulates the resonances (or formants) created as air travels from the lungs, past the vocal folds, and out of the lips to produce a melody. A total of 60 participants, aged 18-60 years (54 men and 6 women), were selected by non-random sampling method using cross-sectional study. X-ray, endoscopy, and sound research method were used in the study, and the composition of blood gas was analysed. X-ray examination determined the state during each different types of Khuumii; Shakhaa and Kharkhiraa. As the basic timbre of Shakhaa Khuumii went up progressively the larynx grew and the compression strength increased, while the basic timbre went down, and the larynx became lower. In the case of Kharkhiraa Khuumii, the larynx position was elevated to a relatively small extent compared to Shakhaa Khuumii and the distance between the sublingual bone and the larynx was large. The sublingual bone trunk lowered during Shakhaa Khuumii, while it was slightly elevated during Kharkhiraa Khuumii. The laryngeal endoscopy evaluated the movement of true and false vocal chords, glottal volume, movements of epiglottis and arytenoid cartilage, and mucosa. Furthermore, the sound frequency is 2-4 times higher than that of normal speech, and sound volume is 0.5-1 times higher. The blood gas composition test showed partial pressure (pO2), and saturation of oxygen (SaO2) decreased after performing Khuumii. In the case of Shakhaa and Kharkhiraa Khuumi, it is appropriate to divide Khuumii into two main types according to structural and functional changes in the organs involved

HER3-targeted protein chimera forms endosomolytic capsomeres and self-assembles into stealth nucleocapsids for systemic tumor homing of RNA interference in vivo.
RNA interference represents a potent intervention for cancer treatment but requires a robust delivery agent for transporting gene-modulating molecules, such as small interfering RNAs (siRNAs). Although numerous molecular approaches for siRNA delivery are adequate in vitro, delivery to therapeutic targets in vivo is limited by payload integrity, cell targeting, efficient cell uptake, and membrane penetration. We constructed nonviral biomaterials to transport small nucleic acids to cell targets, including tumor cells, on the basis of the self-assembling and cell-penetrating activities of the adenovirus capsid penton base. Our recombinant penton base chimera contains polypeptide domains designed for noncovalent assembly with anionic molecules and tumor homing. Here, structural modeling, molecular dynamics simulations, and functional assays suggest that it forms pentameric units resembling viral capsomeres that assemble into larger capsid-like structures when combined with siRNA cargo. Pentamerization forms a barrel lined with charged residues mediating pH-responsive dissociation and exposing masked domains, providing insight on the endosomolytic mechanism. The therapeutic impact was examined on tumors expressing high levels of HER3/ErbB3 that are resistant to clinical inhibitors. Our findings suggest that our construct may utilize ligand mimicry to avoid host attack and target the siRNA to HER3+ tumors by forming multivalent capsid-like structures
