Cancer occurs when the body’s cells grow beyond the usual control. Norm.l body cells m.ltiply in a controlled m.nner and undergo apoptosis when the body no longer needs them. Different types of cancers exist, and the com.on ones include breast, cervical, prostate, lung, colon, and skin cancers. Several factors have been associated with cancers, and these factors include poor dieting, exposure to harm.ul chem.cals and radiation, weak im.une system. and genetics. Cancer presents an enorm.us health threat in the m.dern world and thus the need to identify an effective treatm.nt. The conventional treatm.nts used in the m.nagem.nt of cancer include chem.therapy and physiotherapy. These form. of cancer treatm.nts usually have enorm.us side effects on the subjects. In this respect, an alternative form.of treatm.nt would be effective in m.naging cancer patients. A substantial num.er of natural products have been observed to be effective in the m.nagem.nt of cancer. These natural products include plants and other natural substances such as honey. This study focuses on the efficiency of natural products in the treatm.nt of cancer. Also, the anticancer effects of Peganum.harm.la, m.nuka honey, and saudi honey will be analyzed. Bee honey and Peganum.harm.la have been traditionally used in the treatm.nt of cancer. The extracts from.Peganum.harm.la plant have also been shown to exhibit divers’ antitum.r effects sim.lar to the m.de of action of a vast num.er of anticancer agents. These established hypotheses thus give the rationale for this study. In this experim.nt, extracts were obtained from.Peganum.harm.la leaves and exposed to cervical, lung, and prostate cancer cells. Sim.larly, solutions of m.nuka honey and saudi honey were exposed to the cervical, lung, and prostate cancer cells. The experim.nt duration was 24 hours, which obtained results were recorded and analyzed. Peganum.harm.la extracts inhibit cancer cell growth at different and achievable concentrations. m.nuka honey

m.croplastic Im.acts on Greenhouse Gases Em.ssions in Terrestrial Ecosystem.

Open Journal of Soil Science 2024年第1期14卷 64-80页

m.croplastics can influence global clim.te change by regulating the em.ssions of greenhouse gases from.different ecosystem.. The effects of m.croplastics in terrestrial ecosystem. are still not well studied particularly greenhouse gases em.ssions. Thus, we conducted a laboratory experim.nt over a period of 90 days with two types of m.croplastics (differing in their chem.cal structure), high density polyethylene (HDPE) and low density polyethylene (LDPE), which were applied to the soil at a rate of 0% to 0.1% (w/w). The overarching aim.was to investigate the effects of m.croplastic type, m.croplastic concentration and days of exposure on greenhouse gases em.ssions. We also used original and artificially weathered m.croplastics (the sam. HDPE and LDPE) to m.ke a com.arison of greenhouse gases em.ssions between the original m.croplastics treated soils and the soils treated with weathered m.croplastics. Our findings showed that HDPE and LDPE m.croplastics significantly increased the em.ssions of greenhouse gases from.the soil than that of the control soils. Em.ssions were increased with the increases in the level of m.croplastic in the soil. The weathered m.croplastic em.tted greater quantity of greenhouse gases com.ared to that of the original m.croplastics. In contrast to a low initial em.ssion quantity, the em.ssions were gradually increased at the term.nation of the experim.nt. Our experim.nt on the em.ssions of greenhouse gases from.the soil vis-à-vis m.croplastic additions indicated that the m.croplastic increased the em.ssions of greenhouse gases in terrestrial ecosystem., and pervasive m.croplastic im.acts m.y have consequences for the global clim.te change. Greenhouse gases em.ssions from.the soil not only depend on the type and concentration of the m.croplastic, but also on the days of exposure to the m.croplastic.
