A IMPLEMENTAÇÃO DA EDUCAÇÃO A DISTÂNCIA NO SISTEMA PENITENCIÁRIO: EFETIVAÇÃO DOS DIREITOS FUNDAMENTAIS E RECONHECIMENTO DA DIGNIDADE HUMANA DO APENADO

O presente artigo reporta sobre o direito à educação à distância aos apenados que estejam cumprindo pena no sistema penitenciário, como forma de reconhecimento da dignidade humana do ser encarcerado e uma proposta de efetivação de seus direitos fundamentais e da personalidade. A educação é um instrumento de liberdade e integra o núcleo essencial dos direitos que conduzem à cidadania. É possível afirmar que se trata de direito fundamental, necessário à formação do ser humano, inserido no conteúdo do mínimo existencial, e, portanto, aspecto fundamental à dignificação humana e à ressocialização do apenado. O objetivo deste estudo é analisar, através do método hipotético-dedutivo, que a educação, na modalidade à distância, proporciona a democratização do acesso à informação, à cultura, à formação e, consequentemente, às condições mais dignas de vida ao encarcerado. Assim, se comprovará que a educação se trata de um elemento caracterizador do mínimo existencial e o seu exercício não pode ser postergado, necessitando da atuação prioritária e efetiva do Estado. A principal forma de atuação estatal é por intermédio das políticas públicas, que, nesta pesquisa, configuram-se nas políticas públicas educacionais de promoção humana.   

ENSINO EM EMPREENDEDORISMO NO CURSO DE ADMINISTRAÇÃO EM DUAS INSTITUIÇÕES DE ENSINO SUPERIOR PÚBLICAS DO ESTADO DO PARANÁ

O empreendedor é visto como o agente que, de forma inovadora, provoca mudanças econômicas por meio da introdução de novos produtos e serviços, novas formas organizacionais, novos empreendimentos. O ensino em empreendedorismo é capaz de auxiliar na formação de empreendedores, pois as habilidades destes podem ser adquiridas pelo educando, desde que o educador seja preparado para isto. À luz desta realidade, o objetivo deste artigo é verificar como os projetos pedagógicos dos cursos de Administração da UEM e UEPG abordam o ensino em  empreendedorismo.  Mediante pesquisa descritiva, com abordagem qualitativa, averiguou-se que as instituições mantêm em seus projetos pedagógicos a disciplina de empreendedorismo, mas não foi constatada de forma explícita a intencionalidade de formar o empreendedor. Entretanto, pelo perfil desejado do formando e os objetivos dos cursos,  verificou-se que parte das habilidades empreendedoras são desejadas nos discentes

Zika virus infection in the genital tract of non-pregnant females: a systematic review

This review provides a general overview on the positivity and persistence of Zika virus (ZIKV) in female genital tract (FGT) of non-pregnant women and animals, as well as in cell cultures, and its influence on FGT health. We performed a systematic review based on the PRISMA statement to identify studies focused on “Zika virus” and “non-pregnant female” in PubMed, Embase, Scopus Scholar and Web of Knowledge databases of full-text papers and abstracts published in English, with no restrictions regarding the initial date of publication, up to August 2019. Our search terms yielded 625 records, that were 108 after removal of duplicates, leaving 517 items for title and abstract reviews. Of these, 475 did not meet the inclusion criteria, leaving 42 records for full-text review and resulting in the exclusion of 6 additional records. The remaining 36 met our inclusion criteria. Variations were observed regarding the presence and persistence of ZIKV in lower and upper genital samples. However, the FGT was the place in which ZIKV RNA has been detected, sometimes for relatively long periods, even after the clearance from blood and urine. In addition to the vagina and cervix, the endometrium, uterus and ovary (oocytes and follicles) could also be involved in persistent ZIKV infections. Further prospective studies are needed to assess the effect of ZIKV on FGT health

High molecular prevalence of HPV and other sexually transmitted infections in a population of asymptomatic women who work or study at a Brazilian university

Sexually transmitted infections (STIs) represent a global health problem with variable prevalence depending on the geographical region and the type of population. Human papillomavirus (HPV) encompasses widespread virus types related to cervical carcinogenesis. The present study investigated the molecular prevalence of HPV and seven other important STIs in asymptomatic women working or studying at a Brazilian university. A secondary aim was to assess cytological abnormalities associated with HPV and other STIs coinfections. We recruited 210 women from a Brazilian university. HPV was detected using a single-round polymerase chain reaction (sPCR) followed by a viral genotyping by restriction fragment length polymorphism (RFLP-PCR). The presence of seven STIs: Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, Trichomonas vaginalis, Mycoplasma genitalium, herpes simplex virus (HSV)-1 and HSV-2 was detected by multiplex PCR (M-PCR). Furthermore, cytological findings and epidemiological characteristics were evaluated.The mean age of the participants was 27.1 years old. HPV prevalence was 33.8%, and HPV16 was the most frequently detected papillomavirus genotype. Moreover, multiple HPV infections were common (42.2%). We detected at least one STI agent in 11.4% of the tested women, most frequently C. trachomatis (6.7%). Among HPV-positive women, 14.1% were coinfected with other STI agents. Cytological abnormalities were observed in 9.5% of smears, and HPV-DNA, high-risk HPV (HR-HPV), HPV16 and HPV multiple infections were associated with abnormal cytological findings. There was a high prevalence of HPV, and C. trachomatis was the most prevalent STI agent, with low rates of cytological abnormalities. These findings highlight the need of timely STI diagnosis in young asymptomatic women and of a public policy design for STI prevention

Selective photodynamic effects on cervical adenocarcinoma cells provided by F127 Pluronic®-based micelles modulating hypericin delivery

Cervical cancer is a leading cause of death among women. The endocervical adenocarcinoma (ECA) represents an aggressive and metastatic type of cancer with no effective treatment options currently available. We evaluated the antitumoral and anti-migratory effects of hypericin (HYP) encapsulated on Pluronic F127 (F127/HYP) photodynamic therapy (PDT) against a human cell line derived from invasive cervical adenocarcinoma (HeLa) compared to a human epithelial cell line (HaCaT). The phototoxicity and cytotoxicity of F127/HYP were evaluated by the following assays: colorimetric assay, MTT, cellular morphological changes by microscopy and long-term cytotoxicity by clonogenic assay. In addition, we performed fluorescence microscopy to analyze cell uptake and subcellular distribution of F127/HYP, cell death pathway and reactive oxygen species (ROS) production. The PDT mechanism was determined with sodium azide and D-mannitol and cell migration by wound-healing assay. The treatment with F127/HYP promoted a phototoxic result in the HeLa cells in a dose-dependent and selective form. Internalization of F127/HYP was observed mainly in the mitochondria, causing cell death by necrosis and ROS production especially by the type II PDT mechanism. Furthermore, F127/HYP reduced the long-term proliferation and migration capacity of HeLa cells. Overall, our results indicate a potentially application of F127/HYP micelles as a novel approach for PDT with HYP delivery to more specifically treat ECA

<p>Abstract</p> <p>Background</p> <p>Repetitive sequences are the major components of the eukaryotic genomes. Association of these repeats with transcribing sequences and their regulation in buffalo <it>Bubalus bubalis </it>has remained largely unresolved.</p> <p>Results</p> <p>We cloned and sequenced <it>RsaI </it>repeat fragments pDp1, pDp2, pDp3, pDp4 of 1331, 651, 603 and 339 base pairs, respectively from the buffalo, <it>Bubalus bubalis</it>. Upon characterization, these fragments were found to represent retrotransposons and part of some functional genes. The resultant clones showed cross hybridization only with buffalo, cattle, goat and sheep genomic DNA. Real Time PCR, detected ~2 × 10⁴copies of pDp1, ~ 3000 copies of pDp2 and pDp3 and ~ 1000 of pDp4 in buffalo, cattle, goat and sheep genomes, respectively. <it>RsaI </it>repeats are transcriptionally active in somatic tissues and spermatozoa. Accordingly, pDp1 showed maximum expression in lung, pDp2 and pDp3 both in Kidney, and pDp4 in ovary. Fluorescence <it>in situ </it>hybridization showed repeats to be distributed all across the chromosomes.</p> <p>Conclusions</p> <p>The data suggest that <it>RsaI </it>repeats have been incorporated into the exonic regions of various transcribing genes, possibly contributing towards the architecture and evolution of the buffalo and related genomes.

A novel Bifidobacterium infantis-mediated TK/GCV suicide gene therapy system exhibits antitumor activity in a rat model of bladder cancer

Bladder cancer is the ninth most common malignancy in the world. Successful clinical management remains a challenge. In order To search for novel targeted and efficacious treatment, we sought to investigate anti-tumor activity of BI-TK suicide gene therapy system in a rat model of bladder tumors. We first constructed and tested an anaerobic Bifidobacterium infantis-mediated thymidine kinase (BI-TK) suicide gene therapy system. To test the in vivo efficacy of this system, we established a rat model of bladder tumors, which was induced by N-methyl-nitrosourea perfusion. Bifidobacterium infantis containing the HSV-TK (i.e., BI-TK) were constructed by transformation of recombinant plasmid pGEX - TK. The engineered BI-TK was injected into tumor-bearing rats via tail vein, followed by intraperitoneal injection of ganciclovir (GCV). Using the rat model of bladder tumors, we found that bladder tumor burdens were significantly lower in the rats treated with BI-TK/GCV group than that treated with normal saline control group (p <0.05). While various degrees of apoptosis of the tumor cells were detected in all groups using in situ TUNEL assay, apoptosis was mostly notable in the BI-TK/GCV treatment group. Immunohistochemical staining further demonstrated that the BI-TK/GCV treatment group had the highest level of caspase3 protein expression than that of the empty plasmid group and normal saline group (p < 0.05). Thus, our results demonstrate that the Bifidobacterium infantis-mediated TK/GCV suicide gene therapy system can effectively inhibit rat bladder tumor growth, possibly through increasing caspase 3 expression and inducing apoptosis

Oligosaccharide Binding Proteins from Bifidobacterium longum subsp. infantis Reveal a Preference for Host Glycans

Bifidobacterium longum subsp. infantis (B. infantis) is a common member of the infant intestinal microbiota, and it has been characterized by its foraging capacity for human milk oligosaccharides (HMO). Its genome sequence revealed an overabundance of the Family 1 of solute binding proteins (F1SBPs), part of ABC transporters and associated with the import of oligosaccharides. In this study we have used the Mammalian Glycan Array to determine the specific affinities of these proteins. This was correlated with binding protein expression induced by different prebiotics including HMO. Half of the F1SBPs in B. infantis were determined to bind mammalian oligosaccharides. Their affinities included different blood group structures and mucin oligosaccharides. Related to HMO, other proteins were specific for oligomers of lacto-N-biose (LNB) and polylactosamines with different degrees of fucosylation. Growth on HMO induced the expression of specific binding proteins that import HMO isomers, but also bind blood group and mucin oligosaccharides, suggesting coregulated transport mechanisms. The prebiotic inulin induced other family 1 binding proteins with affinity for intestinal glycans. Most of the host glycan F1SBPs in B. infantis do not have homologs in other bifidobacteria. Finally, some of these proteins were found to be adherent to intestinal epithelial cells in vitro. In conclusion, this study represents further evidence for the particular adaptations of B. infantis to the infant gut environment, and helps to understand the molecular mechanisms involved in this process

BackgroundCervical cancer is a major public health problem in resource-limited settings, particularly among HIV-infected women. Given the challenges of cytology-based approaches, the efficiency of new screening programs need to be assessed.SettingCommunity and hospital-based clinics in Gaborone, Botswana.ObjectiveTo determine the feasibility, and efficiency of the \u201cSee and Treat\u201d approach using Visual Inspection Acetic Acid (VIA) and Enhanced Digital Imaging (EDI) for cervical cancer prevention in HIV-infected women.MethodsA two-tier community-based cervical cancer prevention program was implemented. HIV-infected women were screened by nurses at the community using the VIA/EDI approach. Low-grade lesions were treated with cryotherapy on the same visit.ResultsFrom March 2009 through January 2011, 2,175 patients were screened for cervical cancer at our community-based clinic. 253 (11.6%) were found to have low-grade lesions and received same-day cryotherapy. 1,347 (61.9%) women were considered to have a normal examination and 575 (27.3%) were referred for further evaluation and treatment. Of the 1,347 women initially considered to have normal exams, 267 (19.8%) were recalled based on weekly quality control assessments. 210 (78.6%) of the 267 recalled women and 499 (86.8%) of the 575 referred women were seen at the referral clinic. Of these 709 women, 506 (71.4%) required additional treatment. Overall, 264 CIN stage 2 or 3 were identified and treated, and six micro-invasive cancers identified were referred for further management.ConclusionsOur \u201cSee and Treat\u201d cervical cancer prevention program using the VIA/EDI approach is a feasible, high-output and high-efficiency program, worthy of considering as an additional cervical cancer screening method in Botswana, especially for women with limited access to the current cytology-based screening services.20122014-01-08T00:00:00ZP30 AI045008/AI/NIAID NIH HHS/United StatesU2G PS001949/PS/NCHHSTP CDC HHS/United States1U2GPS001949/PHS HHS/United StatesIP30 AI 45008/AI/NIAID NIH HHS/United States22134146PMC388408
