Tanzania Journal of Science

Comparative in vitro antioxidant activities of aqueous extracts of Garcinia kola and Buchholzia coriacea seeds were carried out using 2, 2-diphenyl 1-picrylhydrazyl (DPPH) free radical scavenging activities, ferric reducing antioxidant power (FRAP) and inhibition of lipid peroxidation assays. Total phenolics, alkaloids, tannins, saponins and flavonoids constituents of the samples were also determined. G. kola seeds contained higher concentrations of secondary metabolites compared to B. coriacea seeds except flavonoids. Both G. kola and B. coriacea exhibited minimum percentage inhibition when compared with the gallic acid. However, B. coriacea exhibited significantly (p < 0.05) higher percentage DPPH scarvenging activities (44.66%) when compared with G. kola (43.62%) at maximum concentration of 100 µg/mL. G. kola on the other hand, showed higher percentage inhibition of lipid peroxidation when compared with B. coriacea at all tested concentrations. Percentage FRAP by B. coriacea was significantly (p < 0.05) higher than G. kola at 100 µg/mL (46.65%, and 38.35%, respectively) and 50 µg/mL (38.75%, and 46.05%, respectively), while lower percentage FRAP of the G. kola than B. coriacea were recorded at 25 µg/mL (24.26% and 38.24%, respectively) and 12.5 µg/mL (34.41% and 37.41%, respectively). Therefore, Garcinia kola and B. coriacea showed appreciable antioxidant activities at varying concentrations and this may be due to the presence of various phenolic compounds in both samples Keywords:    Buchholzia coriacea; Garcinia kola; Antioxidant; DPPH free radicals; Secondary metabolites.

Leaf Traits Can Be Used To Predict Rates Of Litter Decomposition, Marc Rosenfield, Jennifer L. Funk, Jason K. Keller, Catrina Clausen, Kimberlee Cyphers

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Strong relationships exist between litter chemistry traits and rates of litter decomposition. However, leaf traits are more commonly found in online trait databases than litter traits and fewer studies have examined how well leaf traits predict litter decomposition rates. Furthermore, while bulk leaf nitrogen (N) content is known to regulate litter decomposition, few studies have explored the importance of N biochemistry fractions, such as protein and amino acid concentration. Here, we decomposed green leaves and naturally senesced leaf litter of nine species representing a wide range of leaf functional traits. We evaluated the ability of traits associated with leaf and …

Spatial Heterogeneity Utilization In Ct Images For Lung Nodule Classication, Dmitrii Cherezov

USF Tampa Graduate Theses and Dissertations

Lung cancer (LC) is leading in the number of deaths among the other types of cancer. According to the American Cancer Society, 135,720 deaths during 2020 in the USA will be associated with LC. The patient 5-year survival rate of 16\% was reported in 1986 and 19% in 2019. One of the reasons why survival rate remains low is that the majority of patients diagnosed with cancer had stages III and IV. In contrast, a 5-year survival rate of 70% was reported for patients of stage IA after surgical resection in the National Lung Screening Trial.

School of Biological and Marine Sciences

Light is a crucial element for plant growth and production. High-pressure sodium (HPS) lamps are considered not very electrically efficient as they generate high radiant heat, and as a consequence, there has been a lot of interest in replacing HPS lamps with new more efficient lighting sources in the form of light-emitting diodes (LEDs). LEDs have a linear photon output with the electrical input current, and this great feature allows the design of lighting arrays that match the plant’s needs. In the current study, light spectrum absorbance of pigments extracted from 14 plant species was analyzed. Two absorbance peaks were …

Are All Running Training Loads Created Equal?, Megan Renee Ryan

Electronic Theses and Dissertations Archive

Training load (TL) is defined as the product of external and internal loads. Various types of external loads can be used in calculating running TL. The purpose of this study was to compare week-to-week changes among different TL in runners. Nine male cross-country runners participated in two consecutive weeks of training monitoring. Sessions rate of perceived exertion (sRPE) was collected after each run. External loads included miles, minutes, Step Count, Bone Stimulus, and estimated cumulative peak vertical force. Paired t-tests and Cohen's d effect sizes were used to compare between-week percent change (%?) among TL measures and minutes (p< 0.05). Different between-week%? were found between sRPExMinutes (p = 0.002), sRPExStep Count (p = 0.006), sRPExForce (p = 0.002), and miles (p = 0.019) compared to minutes. Findings suggest that using TL allows for more individualized monitoring of the training physiological loads in high school runners.
