    (BMC Research Notes, 2020) Kalange, Muhamudu; Nansunga, Miriam; Kasozi, Keneth Iceland; Kasolo, Josephine; Namulema, Jackline; Atusiimirwe, Jovile Kasande; Ayikobua, Emmanuel Tiyo
    Antimalarials are globally used against plasmodium infections, however, information on the safety of new antimalarial combination therapies on the gastric mucosa is scarce. The aim of this study was to investigate the effects of Artesunate-Amodiaquine and Artemether-Lumefantrine on ulcer induction. Malondialdehyde (MDA), reduced glutathione (GSH) and major histological changes in male Wistar rats following ulcer induction using Indomethacin were investigated. Gastric ulcers were in four groups; Group I was administered Artesunate, group II received Artesunate-Amodiaquine, group III received Artemether-Lumefantrine, and group IV was a positive control (normal saline). Group V was the negative control consisting of healthy rats.Antimalarial combination therapies were associated with a high gastric ulcer index than a single antimalarial agent, Artesunate. In addition, levels of MDA were significantly higher in the combination of therapies while levels of GSH were lower in comparison to Artesunate and the negative control. Microscopically, antimalarial combination therapies were associated with severe inflammation and tissue damage than Artesunate in the gastric mucosa showing that antimalarial combination therapies exert their toxic effects through oxidative stress mechanisms, and this leads to cellular damage. Findings in this study demonstrate a need to revisit information on the pharmacodynamics of major circulating antimalarial agents in developing countries.

    Calcium and s100a1 Protein Balance in the Brain– Heart Axis in Diabetic Male Wistar Rats
    (Journal of Basic and Clinical Physiology and Pharmacology, 2021) Kasozi, Keneth Iceland; Nakimbugwe, Dorothy; Ninsiima, Herbert Izo; Kasolo, Josephine; Matama, Kevin; Owembabazi, Elna; Ssempijja, Fred
    Calcium deregulation in diabetes mellitus (DM) is central to the brain–heart axis pathology. This has led to the use of medical plants in complementary medicine such as Amaranthus hypochondriacus (GA). The objective of the study was to establish the effects of grain amaranth feed supplementation on calcium, s100al protein and antioxidant levels on the brain–heart axis in diabetic male Wistar rats. The study involved six groups (n=5) with DM being induced in 20 rats. To the diabetic rats, Group I received mixtard®, Group II was positive control, Groups III and IV received GA feed supplementation at 25 and 50%. In the nondiabetic rats (n=10), Group V received 50% grain amaranth while Group VI was the negative control. The brain and heart tissues were harvested after five weeks and processed using standard methods. Grain amaranth feed supplementation led to improved calcium levels in DM as compared to the positive control. This also led to increased s100a1, antioxidant levels in the brain–heart axis during DM. This then protected the tissues against oxidative damage, thus preserving tissue function and structure. Grain amaranth’s actions on calcium signaling subsequently affected s100a1 protein levels, leading to improved tissue function in diabetes.

    Low Concentrations of Lactobacillus rhamnosus GG (Yoba®) are Safe in Male Drosophila Melanogaster
    (BMC Research Notes, 2019) Kasozi, Keneth Iceland; Bukenya, Aisha; Eze, Ejike Daniel; Kasolo, Josephine; Tayebwa, Dickson Stuart; Ssempijja, Fred; Suubo, Joy; Tamale, Andrew; Echoru, Isaac; Onkoba, Sarah Kemuma Onkoba
    The purpose of the study was to generate information on the safety of probiotics, thus the study objectives were to evaluate the effects of Yoba® on basic physiochemical properties. The study assessed male w1118 Drosophila melanogaster which were provided food supplemented with Yoba® at 1%, 3%, 6%, and 12% on motor function, total protein, catalase activity, and hydrogen peroxide scavenging activity and lifespan.

    Lycopene Improves on Basic Hematological and Immunological Parameters in Diabetes Mellitus
    (BMC research notes, 2019) Eze, Ejike Daniel; Afodu, Adam Moyosore; Kasolo, Josephine; Kasozi, Keneth Iceland
    Diabetes is associated with an upset of hematological and immunological parameters in humans, however information on the effects of Lycopene is scarce. The aim of the study was to gain information on basic changes in hematological parameters as markers for safety since anemia as a complication in diabetic chemotherapy has been reported.Lycopene had anti-anemic effects and improved on the immune status of diabetic rats and these observations were dose independent. There was a decrease in neutrophil, low neutrophil–lymphocyte ratio and platelet counts and stable albumin, globulin levels. Lycopene could exert its protective effects through a balance of basic hematological physiological variables.

    Synergistic action of propolis with levodopa in the management of Parkinsonism in Drosophila melanogaster
    (Journal of Complementary and Integrative Medicine, 2020) Ayikobua, Emmanuel Tiyo; Kasolo, Josephine; Kasozi, Keneth Iceland; Eze, Ejike Daniel; Safiriyu, Abass; Ninsiima, Herbert Izo; Kiyimba, Kennedy; Namulema, Jackline; Jjesero, Edward; Ssempijja, Fred; Semuyaba, Ibrahim; Kimanje, Kyobe Ronald; Kalange, Muhamudu; Okpanachi, Alfred Omachonu; Nansunga, Miriam
    The Phosphatase and tensin-induced putative kinase 1 (PINK1B9) mutant for Drosophila melanogaster is a key tool that has been used in assessing the pathology of Parkinsonism and its possible remedy. This research was targeted toward determining the effects of ethanolic extract of propolis, with levodopa therapy in the management of Parkinsonism. The PINK1B9 flies were divided into groups and fed with the different treatment doses of ethanoic extract of propolis. The treatment groups were subjected to 21 days of administration of propolis and the levodopa at different doses after which percentage climbing index, antioxidant activity and lifespan studies were done.Propolis alone improved motor activity, antioxidant and lifespan in Drosophila melanogaster than in PINK1 flies. Propolis in combination with levodopa significantly (P<0.05) improved physiological parameters at higher than lower concentrations in Parkinsonism Drosophila melanogaster demonstrating its importance in managing side effects associated with levodopa. Propolis is a novel candidate as an alternative and integrative medicinal option to use in the management of Parkinsonism in both animals and humans at higher concentrations.

    Unique Circulating microRNA Profiles in Epidemic Kaposi’s Sarcoma
    (Research Square, 2020) Muwonge, Haruna; Kasujja, Hassan; Atugonza, Carolyne; Kasolo, Josephine; Lugaajju, Allan; Nfambi, Joshua; Damani, Ali Moses; Sembajwe, Larry Fred; Kimuli, Ivan; Nakazzi, Faith; Nakanjako, Damalie; Kateete, David Patrick; Bwanga, Freddie
    The Human herpesvirus 8 (HHV-8), causes Kaposi's sarcoma (KS). Kaposi sarcoma in HIV/AIDS patients is referred to as epidemic KS, and is the most common HIV-related malignancy worldwide. Lack of a diagnostic assay to detect latent and early stage disease has increased disease morbidity and mortality. Serum miRNAs have previously been used as potential biomarkers of normal physiology and disease. In the current study, we profiled the unique serum miRNAs in patients with epidemic KS to generate baseline data to aid in developing a miRNA-based non-invasive biomarker assay for Epidemic KS. This was a comparative cross-sectional study involving 27 patients with epidemic KS, and 27 HIVpositive adults with no prior diagnosis, or clinical manifestation of KS. DNA and RNA were isolated from blood and serum collected from study participants respectively. Nested PCR for circulating HHV-8 DNA was performed on the isolated DNA, whereas miRNA library preparation and sequencing for circulating miRNA was performed on the RNA samples. The miRge2 pipeline and EdgeR were used to analyze the sequencing data.
