Synthesized arsenic nanoparticles and their high potential in biomedical applications: A review.

Arsenic with the scientific name AS is an element that exists everywhere. It is the fourth among the abundant elements in water, the twelfth in the human body, and the twentieth in the earth's crust. This element exists in sulfide, carbonate, and elemental forms.

Leishmanicidal activities of biosynthesized BaCO (witherite) nanoparticles and their biocompatibility with macrophages.

The aim of this study was cost-effective and greener synthesis of barium carbonate (BaCO or witherite) nanoparticles with economic importance, and to evaluate their therapeutic potentials and biocompatibility with immune cells. Barium carbonate nanoparticles were biosynthesized using black elderberry extract in one step with non-toxic precursors and simple laboratory conditions; their morphologies and specific structures were analyzed using field emission scanning electron microscopy with energy dispersive X-ray spectroscopy (FESEM-EDX). The therapeutic capabilities of these nanoparticles on the immune cells of murine macrophages J774 and promastigotes Leishmania tropica were evaluated.

A review study on the anti-trichomonas activities of medicinal plants.

The parasitic diseases represent the most important health risk, especially in underdeveloped countries where they have a deep impact on public health. Trichomoniasis is a prevalent non-viral sexually transmitted disease, and a significant amount of new cases are identified each year globally. Furthermore, the infection is linked with serious concerns such as pregnancy outcomes, infertility, predisposition to cervical and prostate cancer, and increased transmission and acquisition of HIV.

A systematic review of anti- activity of medicinal plants published in the last 20 years.

Amoebiasis has emerged as a major health problem worldwide. It is endemic in the present scenario is different and sub-tropical regions especially in Asia, Latin America and also in Africa. Causative of amoebiasis is a protozoan known as Entamoeba histolytica.

Calcium carbonate nanowires: greener biosynthesis and their leishmanicidal activity.

The synthesis of inorganic rod shape nanostructures is important in chromatography, dentistry, and medical applications such as bone implants, and drug and gene delivery systems. Herein, calcium carbonate (CaCO) nanowires were synthesized using a plant extract and the ensuing nanoparticles were characterized by XRD, FESEM, and HR-TEM. Then, the leishmanicidal effects of biogenic calcium carbonate nanowires were investigated against including the toxicity of varying concentrations of nanoparticles, and the percentage of viable and apoptotic cells based on flow cytometry analysis.

A lentiviral vaccine expressing KMP11-HASPB fusion protein increases immune response to Leishmania major in BALB/C.

Hydrophilic acylated surface protein B (HASPB) is an immunogenic Leishmania-specific protein that antibodies are produced against it in the sera of Leishmania-infected individuals. Kinetoplastid membrane protein 11 (KMP11) is another Leishmania antigen and considered as the suitable candidate for vaccine development Leishmaniasis. It is a highly conserved surface protein expressed in both promastigotes and amastigotes.

miR-20a inhibition using locked nucleic acid (LNA) technology and its effects on apoptosis of human macrophages infected by Toxoplasma gondii RH strain.

Toxoplasma gondii is a ubiquitous and infectious parasite that multiplies in any nucleated cell of warm-blooded animals and humans worldwide. This parasite has intricate mechanisms to reciprocate host-cell apoptosis to exist in the host cell. So far, the details of the parasite interactions with host cells are not well known.

Locked nucleic acid -anti- let-7a induces apoptosis and necrosis in macrophages infected with Leishmania major.

Background: Protozoan parasites of the genus Leishmania are etiologic agents which are intracellular pathogens of vertebrates and replicate inside infected macrophages. Leishmania have developed complex strategies to reverse host immune responses in favor of it. One of the major species causing cutaneous involvements is Leishmania major.
