Traditional and professional birth attendants influence on womens decisions of birth place and type of birth assistance : a qualitative study in Tang…

2012

Author's version of an article in the journal: Nordisk Sygeplejeforskning. Also available from the publisher at: http://www.idunn.no/ts/nsf/2012/01/art02 Almost half of all Tanzanian women deliver at home, alone, assisted by family members or traditional birth attendants. The aim of this article was to expand existing knowledge on how pregnant and laboring women's preferences and decisions of birth place and type of assistance are influenced. A qualitative study with semi-structured interviews, with two traditional birth attendants and one midwife, and a participatory observation was conducted at a health clinic in Tanga District, Tanzania. It was found that the interaction between pregnant…

Plasma corticosteroids, free fatty acids, insulin and glucose in maternal blood during delivery.

1970

Plasma-corticosteroids (PCS), free fatty acids (FFA), insulin and glucose were determined continously in maternal blood during the entire course of delivery, from the first stage of labour until 6 hours after delivery. A steep increase in the PCS and FFA concentration could be noticed from the onset of labour (PCS: 37,8±11.2 µg/100 ml;\(s_{\bar x} \),p≦0.01; FFA: 556±106.6 µVal/l;\(s_{\bar x} \),p≦0.01) to the birth of the child (PCS: 96.8±19,5 µg/100 ml;\(s_{\bar x} \),p≦0.01; FFA: 1129±220 µVal/l;\(s_{\bar x} \),p≦0.01) and basal levels were already reached 6 hours later (PCS: 36.0±18.5 µg/100 ml;\(s_{\bar x} \),p≦0.01; FFA: 538±192.8 µVal/l;\(s_{\bar x} \),p≦0.01). The rise of insulin an…

Passive exposure to nicotine from e-cigarettes

2016

A procedure based on the use of ion mobility spectrometry (IMS), after liquid-liquid microextraction (LLME), has been successfully employed for the determination of passive exposure to nicotine from cigarette and e-cigarette smoking. Nicotine has been determined in exhaled breath and oral fluids of both, active and passive smokers. The aforementioned studies, made in closed environments, evidenced that the exhaled breath after conventional blend cigarette smoke provides nicotine levels of the order of 220 ng per puff, in the case of experienced smokers, being exhaled only 32 ng in the case of e-cigarettes. On the other hand, the nicotine amount in oral fluids of passive vapers was between 8…

Highly-fluorescent BODIPY-functionalised metallacages as drug delivery systems

2022

With the aim of designing new metallosupramolecular architectures for drug delivery, research has focused on porous 3-dimensional (3D)-metallacages able to encapsulate cytotoxic agents protecting them from metabolism while targeting them to cancer sites. Here, two self-assembled [Pd2L4]4+ cages (CG1 and CG2) featuring 3,5-bis(3-ethynylpyridine)phenyl ligands (L) exo-functionalised with dipyrromethene (BODIPY) groups have been synthesised and characterised by different methods, including NMR spectroscopy and mass spectrometry. 1H NMR spectroscopy studies shows that the cages are able to encapsulate the anticancer drug cisplatin in their hydrophobic cavity, as evidenced by electrostatic poten…

Encapsulation capacity and natural payload delivery of an anticancer drug from boron nitride nanotube.

2016

The behavior of confined anticancer carboplatin (CPT) molecules in a single (10, 10) boron nitride nanotube (BNNT) was studied by means of molecular dynamics simulations. Our study revealed a very large storage capacity of BNNT. Analysis of the energy profiles depending on the number of confined molecules, and on their spatial organization allowed us to quantify the ability of BNNT to vectorize CPT. Indeed, BNNT despite its small radius presented a large inner volume that favored stable encapsulation of multiple active anticancer molecules. Moreover, in our molecular dynamics simulations, the empty BNNT and the BNNT filled with CPT diffused spontaneously to the cell membrane and were able t…

Brain Tumor-Derived Extracellular Vesicles as Carriers of Disease Markers: Molecular Chaperones and MicroRNAs

2020

Primary and metastatic brain tumors are usually serious conditions with poor prognosis, which reveal the urgent need of developing rapid diagnostic tools and efficacious treatments. To achieve these objectives, progress must be made in the understanding of brain tumor biology, for example, how they resist natural defenses and therapeutic intervention. One resistance mechanism involves extracellular vesicles that are released by tumors to meet target cells nearby or distant via circulation and reprogram them by introducing their cargo. This consists of different molecules among which are microRNAs (miRNAs) and molecular chaperones, the focus of this article. miRNAs modify target cells in the…

Cancer screening and health system resilience: Keys to protecting and bolstering preventive services during a financial crisis

2012

The aim of this paper is to elucidate the rationale for sustaining and expanding cost-effective, population-based screening services for breast, cervical and colorectal cancers in the context of the current financial crisis. Our objective is not only to promote optimal delivery of high-quality secondary cancer prevention services, but also to underline the importance of strengthening comprehensive cancer control, and with it, health system response to the complex care challenges posed by all chronic diseases. We focus primarily on issues surrounding planning, organisation, implementation and resources, arguing that given the growing cancer burden, policymakers have ample justification for e…

Anti-tumor activity of CpG-ODN aerosol in mouse lung metastases

2013

Studies in preclinical models have demonstrated the superior anti-tumor effect of CpG oligodeoxynucleotides (CpG-ODN) when administered at the tumor site rather than systemically. We evaluated the effect of aerosolized CpG-ODN on lung metastases in mice injected with immunogenic N202.1A mammary carcinoma cells or weakly immunogenic B16 melanoma cells. Upon reaching the bronchoalveolar space, aerosolized CpG-ODN activated a local immune response, as indicated by production of IL-12p40, IFN-γ and IL-1β and by recruitment and maturation of DC cells in bronchoalveolar lavage fluid of mice. Treatment with aerosolized CpG-ODN induced an expansion of CD4+ cells in lung and was more efficacious tha…
