Melatonin (Mel) is a conserved chemical that has been found in far-removed evolutionary organisms. Additionally, it has been proposed that Mel is a stand-alone plant growth regulator whose action is presumably similar to that of IAA and may moderate the effects of other plant growth regulators. Twelve medicinal herbs were divided into parts, and their melatonin concentrations were measured. These plants Ziziphus spina-christi, , Eucalyptus comaldulensis, Melissa officinalis, Alhagi maurorum, Lavandula angustifolia, Vitex agnus-sactus, Piper nigrum, Hordeum vulgare, Matricaria chamomilla, Borago officinalis, Solanum lycopersicum and Citrus aurantium .

Obesity is documented as a significant health concern and considered a primary risk factor for the progression of many diseases, such as hypertension, diabetes, malignancies, and periodontitis. Proinflammatory cytokines released in response to these health conditions are of great importance and establish the link between diagnosis and treatment. The present study was conducted to assess levels of chemerin and visfatin in saliva and to evaluate the impact of obesity on periodontitis. Ninety participants were included in the study and dived into three groups: (Group I: obese and periodontitis

Show MoreIn this paper, the conditions under which the occurrence of the local bifurcation (such as saddle-node (SN), transcritical (TC), and pitchfork (PT)) of all stable points of a food web model have been investigated. Fear and anti-predator responses involving the Holling-type IV and Growly-Martin functional responses have been found. It has been shown that there are transcritical and pitchfork bifurcations near H3, H4, and H6 as well as a saddle-node bifurcation close to the positive equilibrium point. In addition, there is a saddle-node bifurcation in close to the positive equilibrium point. These divergences have materialised into existence. In conclusion, To prove that the analytical
... Show MoreThe problem of estimating the number of clusters k is considered one of the major challenges for partition clustering. The k-means algorithm is a division-based clustering method where only objects are entered into a set of K, and the algorithm decides the number group initially, but there is no specific way to estimate the best number for the cluster. The outcome of the clustering process can be better after being performed in more than one attempt. Therefore, the optimal count of iterations can be identified through a steady method in advance that can determine the time and number of rounds. So, the problem is finding the optimal number (k) in an easy and fast way. The aim of this paper is to use a genetic algorithm (GA) with

... Show MoreThe complexation between folic acid and a typical polyaromatic hydrocarbon, fluorene, was investigated using FTIR and UV spectra. Appearance of a new IR band at 2401cm−1 demonstrates that NH2–C=N moiety on pterin ring in folic acid is protonated when fluorene is introduced. The emergence of two charge transfer bands at 217 nm and 278 nm in UV difference spectra shows the presence of π-π complexation between folic acid and fluorene. These experiments confirm that fluorene could combine with the pterin ring of folic acid through π-π donor–acceptor interaction and induce the protonation process in folic acid upon strengthening electron accepting ability of pterin ring. The results suggest that complexatio
