Current diagnosis can detect cancer in late stages when therapy options become limited. Early diagnosis is broadly recognized as the key to a better treatment to save lives. The metabolomics approach provides a better understanding of the different types of cancer. They offer promising and potential interventions in biomarkers discovery which eventually will be better suited for individualized medicine. It elucidates endpoint products for other omic processes while significantly improving the understanding of pathogenesis and mechanisms yet to be discovered. Metabolomics offers a less-invasive, cost-effective for predicting, screening, diagnosis, prognosis, and monitoring therapeutic responses of the disease. There are two methods to study the metabolism and metabolites: targeted and untargeted. The workflow of these approaches requires different analytical platforms, such as Nuclear Magnetic Resonance spectroscopy (NMR), Mass Spectrometry (MS), and different bioinformatic tools. This review provides a systematic summary of metabolomics methods in identifying metabolic biomarkers of cancers (colorectal, prostate, breast, bladder, pancreas, lung, and buccal cancers). In addition, the current review will try to shed light on DNA lesions as a potential metabolic biomarker for cancer.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41836231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the composition of honey is dependent on the types and origin of bees’ foods, which are flower nectar and plant honeydew. Thus, this study was done to investigate the influence of spatial variation on the physicochemical and mineral content of stingless bee honey in Terengganu, Malaysia. Honeys produced by Heterotrigona itama were collected from five different locations around Terengganu, Malaysia that are surrounded by different plant diversity. The physicochemical properties, antioxidant activity, total phenolic compounds, total flavonoid compounds, and minerals of stingless bee honey were evaluated. Results obtained show that the pH of honey at all locations differed significantly, ranging from 3.30 to 3.54. The sweetness of honey varied between locations, from 69.30 to 75.76 °Brix. The moisture content of honey ranged from 27.28 to 33.13% and the electrical conductivity from 0.65 to 1.46 mScm -1 , which differed significantly among the five selected locations. The parameters for colour, L* (lightness of the sample), a* (the colour scale from red to green) and b* (the colour scale from yellow to blue) values ranged from 25.02 to 52.55, - 0.12 to 7.42, and 10.36 to 14.88, respectively. The total flavonoid content of honey ranged from 1.41 to 6.64 mg CE/g, while total phenolic content gave a value of 3.94 to 10.54 mg GAE/g. The antioxidant activity of honey gave a value ranging from 71.14 to 85.27%. The location of hives had a significant influence on the amount of minerals in stingless bee honey. It can be concluded that the physicochemical properties and mineral content of honey produced by H. itama were different between locations due to the variation of plant diversity at respective locations.

The cultivation of mushrooms with solid substrates was previously reported to improve their chemical compositions and bioactivities. The effect of the solid-state cultivation of H. erinaceus using jasmine rice media was evaluated with regard to the nutritional value, mycochemicals, and antioxidant activities of the cultivated products. White jasmine rice (R1) and a mixture of white and red jasmine rice (R2) were used as growth substrates for H. erinaceus . The products of their cultivation, such as rice-fermented mycelia (MR1 and MR2) and basidiomata (BR1 and BR2), were assessed to determine their nutritive contents, mycochemicals, and antioxidant activities compared to unfermented rice (R1 and R2) and commercial basidiome (BS). The nutritional values were measured quantitatively, while the mycochemicals were evaluated qualitatively. The antioxidant activity was measured using the level of DPPH scavenging activity. The results showed that H. erinaceus was successfully cultivated on jasmine rice media. The pH of the media was positively correlated with mycelia growth. The R2-fermented mycelium (MR2) product had higher protein levels (11.40 g/100g) compared to unfermented R2 (6.74 g/100g). Basidiome cultivated on R2 media (BR2) exhibited higher protein levels (15.06 g/100g) compared to commercial basidiome (BS) (10.45 g/100 g). The rice-fermented mycelia contained alkaloids, terpenoids, and saponins. The MR2 sample showed the highest level of antioxidant activity (IC 50 =1.26 mg/ml).

In this study the toxicity of both SlNPV and the insecticide synergist pipronyl butoxide (PBO) was investigated against 2 nd and 4 th instar S. littoralis larvae. Different concentrations of the tested viral isolate used (10 6 , 10 7 , 10 8 , 10 9 and 10 10 POB/ml) showed high mortality percentage ranging from 60 to 93% and 56 to 83% for the two tested instar larvae respectively 10 days post treatment. The three PBO concentrations used (0.1, 0.2 and 0.3%) revealed weak toxic effect as they produced 13, 20 and 26% mortality rate for the three tested concentrations respectively 4 days post treatment. To examine the biosafety of the three PBO concentrations (0.1, 0.2 and 0.3%), alone or in combination with SlNPV; in vivo animal studies, and in vitro cell line studies were applied. In vivo evaluations included histomorphometric and immunohistochemical alterations in Caspase-3, Proliferating cell nuclear antigen (PCNA), tumor necrosis factor – alpha (TNF-α) in hepatic and renal tissues, plus serum assessments of malondialdehyde (MDA) and total antioxidant capacity (TAC).
