El objetivo es describir los temas emergentes del fenómeno, los cuales se sistematizan en siete ejes: 1) alteraciones e impacto psicológico; 2) secreto familiar; 3) duelo complicado; 4) estudios sobre la vivencia de la pérdida y la reconstrucción de sí mismo; 5) reestructuración familiar; 6) vulnerabilidad individual y estigmatización; 7) vulneración de los derechos humanos. La investigación con adolescentes y jóvenes es limitada; sin embargo, supone beneficios a ellos y sus familias.

Abstract (analytical) This paper presents a narrative review of the empirical and conceptual production regarding adolescents and young people from Latin America who have been orphaned due to homicide, femicide or the forced disappearance of a parent. The objective is to describe the issues that emerge from this phenomenon. A total of 42 studies that used qualitative approaches were included in this literature review. The findings were systematized in seven thematic areas: 1) alterations, psychological impact and implications for mental health; 2) family secrets and silencing of the incident; 3) complicated grief and chronic suffering; 4) studies on the experiences of loss and the reconstruction of oneself and searching for their own identity; 5) restructuring of families and new roles; 6) individual vulnerability and stigmatization; and 7) violations of human rights. Direct research with adolescents and young people is limited, however when they are included in studies it benefits them and their families.

IgY Antibodies as Biotherapeutics in Biomedicine.

Since the discovery of antibodies by Emil Von Behring and Shibasaburo Kitasato during the 19th century, their potential for use as biotechnological reagents has been exploited in different fields, such as basic and applied research, diagnosis, and the treatment of multiple diseases. Antibodies are relatively easy to obtain from any species with an adaptive immune system, but birds are animals characterized by relatively easy care and maintenance. In addition, the antibodies they produce can be purified from the egg yolk, allowing a system for obtaining them without performing invasive practices, which favors the three "rs" of animal care in experimentation, i.e., replacing, reducing, and refining. In this work, we carry out a brief descriptive review of the most outstanding characteristics of so-called "IgY technology" and the use of IgY antibodies from birds for basic experimentation, diagnosis, and treatment of human beings and animals.

A Key Metabolic Regulator of Bone and Cartilage Health.

Taurine, a cysteine-derived zwitterionic sulfonic acid, is a common ingredient in energy drinks and is naturally found in fish and other seafood. In humans, taurine is produced mainly in the liver, and it can also be obtained from food. In target tissues, such as the retina, heart, and skeletal muscle, it functions as an essential antioxidant, osmolyte, and antiapoptotic agent. Taurine is also involved in energy metabolism and calcium homeostasis. Taurine plays a considerable role in bone growth and development, and high-profile reports have demonstrated the importance of its metabolism for bone health. However, these reports have not been collated for more than 10 years. Therefore, this review focuses on taurine-bone interactions and covers recently discovered aspects of taurine's effects on osteoblastogenesis, osteoclastogenesis, bone structure, and bone pathologies (e.g., osteoporosis and fracture healing), with due attention to the taurine-cartilage relationship.

Estigma internalizado en un grupo LGBT / Internalized Stigma in an LGBT Group

Resumen El objetivo de este artículo es describir el estigma internalizado en un grupo LGBT de Bogotá, Colombia. Se reconocen relaciones de poder y predomina el pensamiento heteronormativo, bicategorial, que configura el estigma sociocultural decantando en un estigma internalizado. Este afecta el desarrollo de sus capacidades y autonomía, limitando un mejor desarrollo humano.

Abstract The objective of this article is to describe the internalized stigma in an LGBT group in Bogota, Colombia. Power relations are recognized and heteronormative, dichotomous thinking predominates, which configures the sociocultural stigma decanting in an internalized stigma. This affects the development of their capabilities and autonomy, by limiting a better human development.

Aberrant sphingomyelin 31P-NMR signatures in giant cell tumour of bone.

An understanding of the biochemistry of the giant cell tumour of bone (GCTB) provides an opportunity for the development of prognostic markers and identification of therapeutic targets. Based on metabolomic analysis, we proposed glycerophospholipid metabolism as the altered pathway in GCTB., The objective of this study was to identify these altered metabolites. Using phosphorus-31 nuclear magnetic resonance spectroscopy (31P-NMR), sphingomyelin was determined to be the most dysregulated phospholipid in tissue samples from six patients with GCTB. Enzymes related to its biosynthesis and hydrolysis were examined using immunodetection techniques. High expression of sphingomyelin synthases 1 and 2, but low expression of neutral sphingomyelinase 2 (nSMase2) was found in GCTB tissues compared to non-neoplastic bone tissues. Sphingomyelin/ceramide biosynthesis is dysregulated in GCTB due to alterations in the expression of SMS1, SMS2, and nSMase2.

Metabolic profiling of serum in patients with cartilage tumours using 1 H-NMR spectroscopy: A pilot study.

Cartilage-forming lesions include tumours that can vary in severity from benign enchondromas to high-grade malignant chondrosarcomas. Chondrosarcoma is the second most frequent malignant bone tumour, accounting for 20-30% of all malignant bone neoplasms. Surgery is the standard treatment for cartilage tumours (CTs); however, their incidental diagnosis and the difficult differentiation of low-grade lesions like chondrosarcoma grade I from benign entities like enchondroma are challenges for clinical management. In this sense, the search for circulating biomarkers for early detection and prognosis is an ongoing interest. Targeted metabolomics is a powerful tool that can propose potential biomarkers in biological fluids as well as help to discover disturbed metabolic pathways to reveal tumour pathogenesis. In this context, the aim of this study was to investigate the 1 H nuclear magnetic resonance metabolomic serum profile of patients with CTs contrasted with healthy controls. Forty-one metabolites were identified and quantified; the multivariate statistical methods principal component analysis and partial least squares discriminant analysis reveal a clear separation of the CT group, that is, the differential metabolites that were involved in two main metabolic pathways: the taurine and hypotaurine metabolism and synthesis and degradation of ketone bodies. Our results represent preliminary work for emergent serum-based diagnostics or prognostic methods for patients with chondrogenic tumours.

Dietary chia seeds (Salvia hispanica) improve acute dyslipidemia and steatohepatitis in rats.

Chia seeds (Salvia hispanica L.) are rich in omega fatty acids. Dyslipidemia and steatohepatitis are diseases that require effective treatments in obese and non-obese patients. The aim was to evaluate the effect of chia intake on acute tyloxapol (TI)-induced dyslipidemia, on acute carbon tetrachloride (TC)-induced steatohepatitis, and on mixed damage (TC+TI) in non-obese rats. Four experimental groups were fed for 4 weeks a diet with established rodent food (DE), and four groups were fed a diet with 15% added chia (DC). Plasma samples were analyzed for total cholesterol, triglycerides, glucose, biochemical liver damage markers, and tumor necrosis factor-α (TNF-α). Liver samples were used to quantify glycogen, catalase, lipid peroxidation, and TNF-α. A histopathological analysis was performed. DC intake partially or totally prevented steatohepatitis, and reduced lipids in the dyslipidemic groups. The hypolipidemic and hepatoprotective effects of chia may be correlated to its high content of α-linolenic acid (omega-3) and phenolics. PRACTICAL APPLICATIONS: Metabolic syndrome is associated with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH), which are currently the most common causes of chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. Dyslipidemia is a significant risk factor for NAFLD and NASH. Non-obese patients may have NAFLD or NASH. Metabolic syndrome and dyslipidemia are more strongly associated with NAFLD in non-obese than in obese patients. This is the first study evaluating the hypolipidemic and hepatoprotective effects of chia seed intake on acute dyslipidemia and/or steatohepatitis caused by the individual or combined administration of the inducers tyloxapol and carbon tetrachloride, respectively, in non-obese rats. The pharmacological effects of dietary chia are correlated to its high content of omega-3 and omega-6 (1:1), protein, dietary fiber, and phenolics. The results suggest that inclusion of chia in diets of non-obese patients with dyslipidemia and/or NAFLD/NASH may improve their health state and preventing cirrhosis or HCC.

Beneficial and Deleterious Effects of Female Sex Hormones, Oral Contraceptives, and Phytoestrogens by Immunomodulation on the Liver.

The liver is considered the laboratory of the human body because of its many metabolic processes. It accomplishes diverse activities as a mixed gland and is in continuous cross-talk with the endocrine system. Not only do hormones from the gastrointestinal tract that participate in digestion regulate the liver functions, but the sex hormones also exert a strong influence on this sexually dimorphic organ, via their receptors expressed in liver, in both health and disease. Besides, the liver modifies the actions of sex hormones through their metabolism and transport proteins. Given the anatomical position and physiological importance of liver, this organ is evidenced as an immune vigilante that mediates the systemic immune response, and, in turn, the immune system regulates the hepatic functions. Such feedback is performed by cytokines. Pro-inflammatory and anti-inflammatory cytokines are strongly involved in hepatic homeostasis and in pathological states; indeed, female sex hormones, oral contraceptives, and phytoestrogens have immunomodulatory effects in the liver and the whole organism. To analyze the complex and interesting beneficial or deleterious effects of these drugs by their immunomodulatory actions in the liver can provide the basis for either their pharmacological use in therapeutic treatments or to avoid their intake in some diseases.

Dimensión interaccional de las configuraciones familiares en adolescentes fumadores / Interactional dimension of family configuration on adolescent smokers

Objetivo: Analizar la dimensión interaccional de la configuración familiar en adolescentes fumadores. Método: Diseño cualitativo de tipo interpretativo mediante estudio de caso. Incluyó a 28 adolescentes fumadores de laPreparatoria No. 5 de la Universidad de Guadalajara, Jalisco México. A todos se les realizó una entrevista semiestructurada, mediante análisis narrativo. Resultados: Se identificó una configuración interaccional caracterizada por padres que no se involucran en los hechos relevantes de la vida de los adolescentes fuera del hogar, la presencia de secreto familiar para encubrir el tabaquismo adolescente, patrones familiares contradictorios: de lo prohibitivo a lo permisivo sobre el uso de tabaco. Los padres varones ofrecieron a sus hijos del mismo sexo estrategias para fumar sin ser descubiertos; persistió la desconfianza parental expresada en largos interrogatorios ante la solicitud de un permiso. Conclusión: Las configuraciones familiares de los adolescentes con tabaquismo actual mostraron disfuncionalidad en la dimensión interaccional que los hace altamente susceptibles al tabaquismo. La interacción en torno al secreto familiar,el enojo y consejos superficiales sin mayor indagación, juegan un papel importante en la conducta tabáquica de los adolescentes, por cuanto se convierten en unpatrón de intercambio que permite un manejo velado de esta adicción(AU)

Objective: To analyze the interactional dimension of family configuration in adolescent smokers. Method: A qualitative interpretative design-based research through case study included 28 adolescent smokers from the pre-university school No. 5 of University of Guadalajara in Jalisco, Mexico. A semi-structured interview was administered to all of them through a narration analysis. Results: Interactional configuration characterized by parents not involved in the relevant facts of adolescents' lives outside the home, the presence of family secret to cover up adolescent smoking and contradictory family patterns ranging from prohibition to authorization of smoking was identified. Fathers provided their male children with some strategies for smoking without being discovered; parental distrust persisted in the form of lengthy interrogations when they ask for permission to smoke. Conclusion: The family configurations of smoking adolescents at present show impaired functionality in the interactional dimension, which makes them highly exposed to smoking. The interaction of family secrecy, anger and slight advising with no further inquiry plays a fundamental role in the smoking behavior of adolescents; since they become a sort of pattern of exchange that allows the veiled management of this addiction(AU)

Evaluation of antioxidant and hepatoprotective effects of white cabbage essential oil.

CONTEXT: There have been no reports of the extraction of essential oil (EO) from white cabbage [Brassica oleracea L. var. capitata (L.) Alef. f. alba DC. (Brassicaceae)] (Bocfal) or its chemical composition, antioxidant activity, or hepatoprotective effects. OBJECTIVE: To extract Bocfal EO, to identify and quantify its chemical components, to assess their antioxidant capacity, and to evaluate the hepatoprotective properties of Bocfal EO. MATERIALS AND METHODS: Bocfal EO was obtained using hydrodistillation (200 mm Hg/58 °C). The chemical composition was analyzed using GC-MS and was quantified using GC-FID. The antioxidant activity of Bocfal EO and its main constituents was evaluated using TBARS in rat brain homogenates. A Bocfal EO hepatoprotective effect (192 mg/kg) on acute carbon tetrachloride (CT)-induced liver damage was determined in rats using biochemical markers and histological analysis. Diallyl disulphide (DADS) (1 mmol/kg) was used as a control for comparison. RESULTS: Bocfal EO contained organic polysulphides (OPSs), such as dimethyl trisulphide (DMTS) 65.43 ± 4.92% and dimethyl disulphide (DMDS) 19.29 ± 2.16% as major constituents. Bocfal EO and DMTS were found to be potent TBARS inhibitors with IC50 values of 0.51 and 3 mg/L, respectively. Bocfal EO demonstrated better hepatoprotective properties than did DADS (p < 0.05), although both slightly affected the hepatic parenchyma per se, as observed using histopathology. DISCUSSION AND CONCLUSION: The antioxidant properties of Bocfal EO and DMTS may be the mechanism of hepatoprotective action; the parenchymal disturbances by Bocfal EO or DADS alone may be related to the high doses used.

Structural dimension: family composition of adolescent smoking in public school of guadalajara, mexico

This study was performed in a high school on a metropolitan area of Guadalajara Jalisco, Mexico. Objective: To analyze the structural patterns of the families of adolescent smokers in a public high school of Universidad de Guadalajara. Method: A qualitative study with 28 adolescent smokers. Family relationships, rules, boundaries, hierarchy, and movements and reactions of parents and its relation to smoking were evaluated by semi structured interviews. A narrative analysis of the transcribed interviews was conducted. Results: The relationship between parents and teenagers were characterized by poor emotional connection, the existence of alliances and coalitions to keep secret smoking. The existence of family rule prohibiting smoking, and the coexistence of little clarity about the consequences for their violation, the presence of a father/mother/ brother smoking tobacco accomplice to keep secret and inefficient movements and reactions of parents against their smoking teens. Conclusions: The patterns familiar adolescent smokers included structural dysfunctions in vital areas of operation: low connection family relationships, alliances and coalitions to keep secret smoking, smoking and porous borders with ineffective monitoring movements to smoking. This configuration provides a high permittivity for installation of addiction.

Effect of Heterotheca inuloides essential oil on rat cytoskeleton articular chondrocytes.

Osteoarthritis is characterised by progressive loss of articular cartilage through the increase of catabolic metalloproteinases, and chondrocyte cytoskeleton disruption has also been reported. In this regard, we studied the effect of Heterotheca inuloides essential oil (HIEO) on the distribution and immunolocalisation of actin, vimentin and tubulin of chondrocytes from cultured rat articular cartilage explants in the presence of the cytoskeleton disassembly agent acrylamide. After 48 h, chondrocytes treated with acrylamide showed changes in actin immunolocalisation and shrinkage, loss of tubulin compartmentalisation and vimentin collapse and redistribution. However, the immunostaining pattern of these three proteins in acrylamide- and HIEO-treated chondrocytes simultaneously retained their typical characteristics. These results suggest that HIEO promotes protein cytoskeleton reorganisation without providing a preventive effect of acrylamide-associated disassembly. However, it is also possible that HIEO prevents vimentin disorganisation by chemical interaction with acrylamide.

Monoarthritis of the knee with unusual lesions in adults associated with varicella-zoster virus infection.

Varicella-zoster virus-associated arthritis has not been well documented in adults. We present the case of a 27-year-old female patient with monoarthritis of the knee associated with clinical symptoms typical of varicella. Arthroscopic examination showed unusual oval and circular lesions in cartilage, some of which measured 5 +/- 3 mm in diameter in weight-supporting zones. Such lesions have not been described previously and were type III-A lesions on the Noyes scale or grade IV on the Outerbridge scale. On microscopic observation, synovial fluid cultures and hemocultures were negative for the presence of bacteria. A biopsy sample and synovial liquid from the affected knee produced a positive polymerase chain reaction for varicella-zoster virus, genotype E. These findings suggest a strong relation between clinical varicella infection and important lesion invasion in the knee articulation of such a young adult, probably related to the virus. However, it remains necessary to corroborate this relation between cartilage destruction and clinical symptoms of varicella associated with monoarthritis of an adult knee. Nevertheless, it is advisable to initiate the appropriate antiviral treatment in adults with varicella-related gonalgia because the lesions produce the most severe effects on exposure to the knee bone.
