The social development scene in Bangladesh is characterised by a strong presence of non-governmental organizations (NGOs). The NGOs emerged following the war of liberation to help the communities in distress as part of post-war rehabilitation. Afterwards, with assistance from foreign donor agencies, they expanded their activities to deliver a variety of services including microcredit, essential...
Non-government organisation engagement in the sanitation sector: opportunities to maximise benefits.
Non-government organisations (NGOs) have long played a role in delivering sanitation services to communities in Southeast Asia and Pacific countries, particularly in rural areas. In contrast with large scale infrastructure focused initiatives, NGO programs commonly focus on building linkages between technical and social realms. Drawing on the breadth and depth of NGO experiences, there are oppo...
In biomedical applications, polyethylene glycol (PEG) functionalization has been a major approach to modify nanocarriers such as nano-graphene oxide for particular biological requirements. However, incorporation of a PEG shell poses a significant diffusion barrier that adversely affects the release of the loaded drugs. This study addresses this critical issue by employing a redox-responsive PEG...
Neisseria gonorrhoeae (Ngo), the etiologic agent of gonorrhea, induce a number of proinflammatory cytokines by contact to epithelial cells. Cytokine genes and a variety of other immune response genes are activated as a result of the regulatory function of immediate early response transcription factors including activator protein 1 (AP-1). Since it is established that phosphorylation of c-Jun, t...
BACKGROUND Infection of the Fallopian tubes (FT) by Neisseria gonorrhoeae (Ngo) can lead to acute salpingitis, an inflammatory condition resulting in damage primarily to the ciliated cells, with loss of ciliary activity and sloughing of the cells from the epithelium. Recently, we have shown that Ngo infection induced apoptosis in FT epithelium cells by a TNF-alpha dependent mechanism that could...
A facile and green strategy is reported for the fabrication of nanosized and reduced covalently PEGylated graphene oxide (nrGO-PEG) with great biocompatibility and high near-infrared (NIR) absorbance. Covalently PEGylated nGO (nGO-PEG) was synthesized by the reaction of nGO-COOH and methoxypolyethylene glycol amine (mPEG-NH2). The neutral and purified nGO-PEG solution was then directly bathed i...
Background Non-governmental organizations (NGOs) have a key role in improving health in low- and middle-income countries. Their work needs to be synergistic, complementary to public services, and rooted in community mobilization and collective action. The study explores how an NGO and its health services are perceived by the population that it serves, and how it can contribute to reducing barri...
Graphene oxide (GO) has been extensively explored in nanomedicine for its excellent physiochemical, electrical, and optical properties. Here, polyethylene glycol (PEG) and polyethylenimine (PEI) are covalently conjugated to GO via amide bonds, obtaining a physiologically stable dual-polymer-functionalized nano-GO conjugate (NGO-PEG-PEI) with ultra-small size. Compared with free PEI and the GO-P...
Introduction Positron emission tomography (PET) tracers has the potential to revolutionize cancer imaging and diagnosis. PET tracers offer non-invasive quantitative imaging in biotechnology and biomedical applications, but it requires radioisotopes as radioactive imaging tracers or radiopharmaceuticals. Method This paper reports the synthesis of 18F-nGO-PEG by covalently functionalizing PEG w...
Neisseria gonorrhoeae (Ngo) has developed multiple immune evasion mechanisms involving the innate and adaptive immune responses. Recent findings have reported that Ngo reduces the IL-1β secretion of infected human monocyte-derived macrophages (MDM). Here, we investigate the role of adenosine triphosphate (ATP) in production and release of IL-1β in Ngo-infected MDM. We found that the exposure of...
