Maximal Strength Training Increases Metabolic Energy Expenditure In Sedentary Adults Classified As Obese, Robert E. Anderson Iii

Theses and Dissertations--Nutrition and Food Systems

Background: Metabolic adaptations reduce resting and non-resting energy expenditure to account for approximately 120 kcal/day. Weight loss promotes greater skeletal muscle efficiency, reducing the energy cost of physical activity and is correlated with declines in skeletal muscle glucose oxidation. Maximal Strength Training (MST) has the potential to upregulate glucose utilization and may offset these metabolic adaptations. Objective: To determine if MST offsets markers of metabolic adaptation by increasing resting and non-resting energy expenditure in sedentary individuals classified as obese. Methods: Five (5) participants (2 females, 3 males), ages 18-35 years, with obesity (BMI 30–45 kg/m2) were enrolled in an 8-week …

Replication Stress Induced By The Ribonucleotide Reductase Inhibitors Guanazole, Triapine, And Gemcitabine In Fission Yeast, Mashael Yahya A Alyahya

Browse all Theses and Dissertations

Replication stress can be produced by various exogenous or endogenous factors that perturb the movement of replication forks. To overcome the stress, the cells provoke the DNA replication checkpoint to mobilize several pathways to protect the forks, maintain genome integrity, and promote cell survival. Defects in the replication checkpoint cause forks collapse, leading to chromosomal DNA damage or cell death. Although the replication checkpoint is crucial for genome integrity in all eukaryotes, the underlying mechanisms remains to be fully understood. To investigate the mechanisms of DRC, hydroxyurea (HU), an established inhibitor of ribonucleotide reductase (RNR), has been widely used in …

The Role Of Action Potential Changes In Depolarization-Induced Failure Of Excitation Contraction Coupling In Mouse Skeletal Muscle, Xueyong Wang, Murad Nawaz, Chris Dupont, Jessica H. Myers, Steve R.A. Burke, Roger A. Bannister, Brent D. Foy, Andrew A. Voss, Mark M. Rich

Physics Faculty Publications

Excitation-contraction coupling (ECC) is the process by which electrical excitation of muscle is converted into force generation. Depolarization of skeletal muscle resting potential contributes to failure of ECC in diseases such as periodic paralysis, intensive care unit acquired weakness and possibly fatigue of muscle during vigorous exercise. When extracellular K+ is raised to depolarize the resting potential, failure of ECC occurs suddenly, over a narrow range of resting potentials. Simultaneous imaging of Ca2+ transients and recording of action potentials (APs) demonstrated failure to generate Ca2+ transients when APs peaked at potentials more negative than –30mV. An AP property that closely …

Sentience And Sentient Minds, John Anthony Webster

Animal Sentience

My commentary builds on Rowan et al.’s (2022) comprehensive review to address the question ‘what do we mean by sentience?’ It suggests how we might recognise degrees of sentience within the animal kingdom, ranging from primitive sensations such as hunger and pain to more complex emotions that determine quality of life.

Koteswara Rao

The Thai Journal of Pharmaceutical Sciences

This study intends to explore the neuroprotective and memory-enhancing properties of Myristica malabarica (MM) leaf extracts on diabetic-induced cognitive decline rats. The models of Y maze and Morris water maze were selected for nootropic activity and neuroprotective properties were deliberate by assessing the levels of Ach, malondialdehyde (MDA), superoxide dismutase (SOD), nitric oxide (NO), catalase (CAT) and glutathione hormone (GSH) in diabetic rat brains. Significantly improved memory and learning with 100 mg/kg (P < 0.01) and 200 mg/kg (P < 0.001) of EAMM (L) and MAMM (L) in Y maze and Morris water maze models. Significant effect was observed in all the extracts with two doses when compared with diabetic control on day 75. The levels of AChE (P < 0.001), MDA (P < 0.01), and NO (P < 0.05) were decreased significantly and significantly raised (P < 0.01) levels of SOD, CAT, and GSH with MAMM (100 and 200 mg/kg) compared with disease control. Further studies on MM leaf are needed as evidence of cognitive impairment in defense against diabetes has been shown to expose its mode of action.

The Thai Journal of Pharmaceutical Sciences

Objectives: The pharmacological basis of anti-inflammatory agents is geared toward maintaining body homeostasis. This study investigated the scientific underpinning and mechanisms of anti-inflammatory activity of root bark of Brenania brieyi. Material and Methods: The plant material was extracted with a mixture of methanol and chloroform (2:1) and fractionated with 0.2 volume water. Egg albumin-induced edema and cotton pellet-induced granuloma models were used to investigate anti-inflammatory activity while the possible mechanisms of actions were evaluated using standard methods. Results: Significant (P < 0.05) reduction in edema and granuloma tissue formation were recorded in fractions treated groups compared with the normal control. There was a significant (P < 0.05) inhibition of membrane hemolysis and phospholipase A2 (PLA2) activity by the fractions compared with the standard drugs, indomethacin, and prednisolone, respectively. Both fractions significantly (P < 0.05) inhibited prostaglandin (PG) synthase and nitric oxide radical activities compared with the control. However, varying doses of both fractions did not inhibit leukocyte migration compared with rats in indomethacin and control groups. The methanol fraction was found to be more potent in most of the tests. Conclusion: These results show that B. brieyi root bark has anti-inflammatory activity, and the potential underlying mechanisms of its action are inhibition of PLA2 and PG involved in inflammatory responses.

Cytotoxic Effect Of Crude Vitex Glabrata Fruit Extracts On Human Cancer Cell Lines, Saraphorn Intarasam, Vorranuch Keerathinant, Mesayamas Kongsema, Kantimanee Pradermwong

The Thai Journal of Pharmaceutical Sciences

Vitex glabrata (VG) or Khai-noa fruit extracts were prepared from three methods; squeezing extract (SE), maceration extract (ME), and ethanol extraction (EE) to evaluate their effects in vitro. By the (1,1-diphenyl-2-picrylhydrazyl) scavenging assay, all extracts revealed very weak antioxidant. Results of (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, a tetrazole) assay showed the increase in cell viability of SE at 100 and 500 μg/ml on TK6 cells after 24 and 48 h treatments (P < 0.01) without affecting Caco-2 cells. Conversely, a dose- and time-dependent cytotoxicity of all extracts revealed at 1000-2000 μg/ml on both cells (P < 0.01). SE showed cytotoxicity on PC-3 cells and anticancer activity when confirmed by clonogenic assay in a dose-dependent manner. SE also showed cytotoxicity on HT-29 cells after 24 h treatment but the cells could recurrent in the clonogenic assay. No effect was observed on MCF-7 cells after SE alone, SE co-treated with MMC treatment, and in the clonogenic assay. Moreover, HT-29 cells revealed a dose-dependent decrease in viability when treated with SE co-treated with MMC by 24 h. Hence, SE can selectively promote cell viability on TK6 and anticancer activity on PC-3. These results suggest that the different potential of SE depends on different cell lines.
