    Get PDF
    Colorectal Cancer (CRC) is dangerous cancer that causes many cases of death in the world. This cancer spike occurred in 2020 with 1.15 million cases and is expected to increase in 2040 by 1.92 million CRC cancer cases. Some of the most popular drugs used for CRC chemotherapy are 5-Fluorouracil, Oxaliplatin, and Irinotecan. The effects caused by chemotherapy using synthetic drugs are loss of appetite, fatigue, vomiting, numbness, hair loss, and low blood cell count. Anthocyanins are a group of flavonoid compounds and polyphenols with antioxidant, antimutagenic, and anticancer activity that can be developed as CRC anticancer. Anthocyanins do not cause side effects in CRC patients. This article is a review of anthocyanin activity to reduce the risk of colorectal cancer (CRC) in terms of molecular mechanisms, the proliferation ability of cancer cells, and promoting apoptosis of CRC cells

    Get PDF
    Background: The hallmark of HIV infection is the progressive loss of immune cells called the CD4 cells weakening the immune system and leaving individuals vulnerable to various opportunistic infections (OIs) and other illnesses, ranging from pneumonia to cancers. Diabetes/hyperglycemia complication on set among the HIV infected has been suggested by several authors although very a minimal interest has been paid on this subject. This study looked at the correlation between hyperglycemia (a risk factor of DM) and HIV infection among HIV-infected individuals in Nyeri County Hospital-Kenya. Methods:  This was a case-control study involving 193 individuals who were grouped into two groups of 97 HIV-positive HIV-Negative individuals (also referred to as study control group) based on negative HIV results and fasting blood glucose level 4.4 ± 2.2mmol/L. and 96 participants who were HIV positive. Results:  A total of 193 individuals were enrolled, grouped into 97 subjects of HIV-negative individuals (control group) and 96 participants who were HIV-positive. In the study 13.54% of HIV-positive were hyperglycemic compared to 6.18% HIV- ve individuals (mean glucose level 7.6 ± 5.1 and 4.4 ± 1.1mmol/L, respectively (P>0.05) r=0.023). Conclusion: The study identified Hyperglycemic as a likely complication in HIV-infected individuals with a need to study the effect of individual diabetes mellitus risk factors in HIV-infected individuals

    Most cyberattacks including data breaches, identity theft, fraud, and other issues, are known to be caused by malware. Some of the malware attacks are categories as adware, spyware, virus, worm, trojan, rootkit, backdoor, ransomware and command and control (C&C) bot, based on its purpose and behaviour. Malware detectors still utilise signature-based approaches to detect malicious software, which can only detect known malware. Attacks by malware pose a serious threat to people's and organizations' cybersecurity globally. These attacks are occurring more frequently and more frequently lately. Over eight billion malware attacks occurred in 2020, up 4% over the previous year, according to a Symantec report. It is crucial that computer users safeguard their computers with a malware detector like an antivirus, anti-spyware, etc. When creating a machine learning model to differentiate between malicious and benign files, it might be challenging to use domain-level expertise to extract the necessary attributes. This research aims to create a malware detector that uses a trained random forest classifier model to find malware and stop zero-day assaults. A dataset (including both harmful and benign software PE header information) was obtained from virusshare.com and used to train the random forest classifier in order to create this malware detector. The Random Forest Classifier generate greater accuracy when compared with other machine learning classifiers, such as KNN (K-Nearest Neighbors), Decision Tree, Logistic Regression etc., the random forest classifier gives a better accuracy of 99.4%. The Classifier model used here will be a better option to use in order to efficiently and effectively detect malware, it shows that the methodology can be utilized as the basis for an operational system for detecting an unknown malicious executable

    A study conducted from January through May 2023 to assess the concentrations of heavy and transitional metals in a commonly used local feed ingredient in a farmed Nile tilapia diet (Oreochromis niloticus) in Tanzania. Eleven fish feed ingredients such as, sunflower seed cake (SFSC), wheat pollard (WP), maize bran (MB), fish meal (FM), freshwater shrimp (FWS), cattle blood meal (CBM), bone meal (BM), soya bean meal (SBM), and rice bran (RB), brewers’ spent grain (BSG) and Taro leaves (Colocasia esculenta; TL) were randomly sampled from feed manufacturers, animal feeds’ centers and other animal feeds suppliers in Arusha  and Dar es Salaam region for inclusion in this study. Heavy metals and transition metals in feed ingredients were analyzed using the Energy-Dispersive X-rays Fluorescence (XRF) (Xla Pro-Spectrometer/German) at the Tanzania Atomic Energy Commission (TAEC) laboratory. The results showed that most of the fish-feed ingredients used in this study comply with the maximum allowable concentrations in Nile tilapia diets-according to the Tanzania bureau of standards and the European commission. However, the results showed that, the concentrations of reported metals (As, Pb, Cd, Hg, Co, Cu, Mo, Mn, Ni, Ag, V, Cr, Fe and Zn) varied significantly (p < 0.05 ) in most of the  analyzed local feed  ingredients collected in Tanzania. The study has paved the way for other researchers to further assess more feed ingredients used not only on heavy metals but other potential contaminants in feeds to ensure sustainable fish farming in Tanzania
