Despite the availability of anticancer drugs, breast cancer remains the most death-causing tumor-related disease in women. Hence, there is a need for discovery and development of efficient alternative drugs, and sources such as plants need to be explored. In this study, antioxidant capacities and inhibitory effects against MCF7 cells of the extracts of stem bark of three Nigerian medicinal plants (Detarium microcarpum, Guiera senegalensis, and Cassia siamea) were investigated. The D. microcarpum extracts had the highest antioxidant and antiproliferative effects, followed by that of G. senegalensis, and the C. siamea extracts had minimal effects. The IC50 values of the methanol and aqueous extracts from the three plants that inhibited the proliferation of MCF7 cells ranged from 78–> 500 μg/ml. Moreover, all the plant extracts but the aqueous extract of Cassia siamea exhibited antimetastatic action and induced apoptosis and cell cycle arrest in MCF7 cells. Liquid chromatography/time-of-flight/mass spectrometry profiling revealed that the five potent extracts contain many phenols and omega-6 fatty acids, and some of the identified compounds (isorhamnetin, eupatorin, alpinumisoflavone, procyanidin B3, syringin, and gallic acid) have been reported to have antiproliferative effects on cancer cells. Hence, the stem bark of these plants could be potential sources of antibreast cancer agents.

A Cross-sectional Study was carried out to determine the prevalence of gastrointestinal (G.I.)  helminths parasites in slaughtered cattle at Azare abattoir, Katagum Local Government Area, Bauchi State, North-Eastern Nigeria. One hundred and twenty faecal samples were examined using the floatation and sedimentation method. Out of the total samples tested, G.I. helminths infections were detected in 62samples tested, giving an overall prevalence of 51.6%. Class nematodes are the most diverse class (56.5%) and then followed by trematodes (35.5%), while cestodes are the least prevalent (8.1%). There was a statistically significant difference in P-value >0.05.  The sex revealed that males (52.6%) are more susceptible to G.I. helminths infection than females (50.0%) even though there is no statistical difference at P-value >0.05. However, the prevalence of G.I. helminths to age revealed a statistical difference at P-value >0.05, where the young have the highest prevalence of 59.5%.  The Red Bororo breeds had the highest prevalence of 75%, while the least was recorded in White Fulani and Sokoto Gudali, 40% each. There was a statistically significant difference at P-value >0.05. This study revealed that Fasciola spp (15%) is the most prevalent G.I. helminths parasites detected, followed by Oesophagostomum spp (11.7%); Haemonchus spp (9.2%); Strongyloides spp (8.3%), Schistosoma spp (3.3%); and Moniezia spp (1.67%). Our findings from the present study revealed a high prevalence of G.I. helminths species affecting cattle in Azare and Nigeria as a whole. Therefore, there is a great need for proper advocacy on the need for appropriate management, regular deworming practices, and improved cattle hygiene to boost animal production. This will help in curbing great lost to Nigeria's economy and the world in general.

This research field has received tremendous attention from researchers because of the many applications of the synthesized nanomaterials in medicine, telecommunication, engineering, and textile industry, to mention but a few (Hanan et al., 2018). In Medicine, nanoparticles are used in drug development and delivery. The nanoparticles are used for the delivery of drug to a specific target in cells, tissues or organs. Nanoparticles can as well be used for infectious disease and cancer therapy (Thakkar et al., 2010; Hanan et al., 2018). There are many physical and chemical methods
