Bioaccumulation Of Trace Metals For Daily Fish Consumption From Selected Former Tin Mining Ponds In Peninsular Malaysia: A Review On Safety Of Fish Consumption, Mohd Hafiz Rosli, Amirul Azuan Md Joni, Nur Khaliesah Abdul Malik Dec 2021

Bioaccumulation Of Trace Metals For Daily Fish Consumption From Selected Former Tin Mining Ponds In Peninsular Malaysia: A Review On Safety Of Fish Consumption, Mohd Hafiz Rosli, Amirul Azuan Md Joni, Nur Khaliesah Abdul Malik

Makara Journal of Science

Tin mining was the predominate mining industry in Malaysia, especially during the mid-19th century. Most of the former mining areas have been reused for aquaculture purposes. Fish produced from former mining areas have been misunderstood as a high health risk if consumed due to their likelihood of containing high heavy metal content in their tissue. Therefore, we review national information on trace metals levels in the tissue of fish from selected former mining ponds in Peninsular Malaysia, together with background concentration of trace metals in their surroundings and food security and human health implications. Seven trace metals (Cu, Zn, As, …

Makara Journal of Science

A photocatalyst supported on magnetic material allows the simple technique by using an external magnetic material to separate photocatalyst from the treated water. Thus, it is a magnetically separable nanoparticles photocatalyst (MSNP). The use of superparamagnetic nanoparticles that do not pose spontaneous magnetic moment thus could be dispersed in water and can be recollected easily by an external magnetic bar. We prepare Fe3O4/SiO2/TiO2 composite by hetero agglomeration of Fe3O4/SiO2 and TiO2 at a pH range of 3 to 6.2 in an aqueous slurry.The Fe3 …

IGC Proceedings (1977-2023)

A long term experiment was set to test the hypothesis that agropastoral systems could improve crop and animal production, being more profitable and sustainable relative to economical, biological and environmental aspects, than continuous and traditional crop and grazing pasture systems. Five farming systems are being tested: two traditional (continuous soybean annual cropping and continuous pasture cropping) and three agropastoral systems (two combinations of four by four years of rotational crop-pasture systems and one by three years of crop-pasture rotation). Animal production in continuous pasture cropping measured as liveweight gain/ha (LWG) are declining along the years in the sub-treatment without fertilizer …

Evaluation Of A Number Of Grass Species For Restoring Degraded Semi-Arid Rangelands In Southern Africa, K. Kellner, S. De Wet

IGC Proceedings (1977-2023)

The biophysical environment is an important determinant of land degradation in both commercial and communal land tenure systems in South Africa. According to a recent study on the status of land degradation, approximately 25% of the total land cover in South Africa is degraded. Several technologies exist to restore the soil and vegetation degraded areas in natural pastures. To improve the production and biodiversity potential for agricultural and conservation uses in these rangelands, a common restoration technology includes the cultivation the eroded and compacted soil surfaces by rip- ploughing and the re-vegetation with high productive, palatable and perennial species.

A Snapshot Investigation Into The Availability And Access To Codeine-Containing Medications Amongst The Irish Population., Katie O'Brien, Pádraig Mckeown, Joseph Phelan

International Undergraduate Journal of Health Sciences

Codeine phosphate is a mild to moderate analgesic and has a weak cough suppressant activity that is available to purchase as an over the counter (OTC) painkiller in Ireland as a compound product. In recent years, countries such as Australia have introduced laws that prohibit the sale of the drug without a valid prescription. This move by Australia begs the question as to why this legislation was introduced and should Ireland follow suit.

The primary aims of the study were to determine knowledge among the general public of codeine-containing medications and their usage levels. The survey also investigated whether current …

Implications Of Salinity Normalization Of Seawater Total Alkalinity In Coral Reef Metabolism Studies, Travis A. Courtney, Tyler Cyronak, Alyssa J. Griffin, Andreas J. Andersson Dec 2021

Implications Of Salinity Normalization Of Seawater Total Alkalinity In Coral Reef Metabolism Studies, Travis A. Courtney, Tyler Cyronak, Alyssa J. Griffin, Andreas J. Andersson

Marine & Environmental Sciences Faculty Articles

Salinity normalization of total alkalinity (TA) and dissolved inorganic carbon (DIC) data is commonly used to account for conservative mixing processes when inferring net metabolic modification of seawater by coral reefs. Salinity (S), TA, and DIC can be accurately and precisely measured, but salinity normalization of TA (nTA) and DIC (nDIC) can generate considerable and unrecognized uncertainties in coral reef metabolic rate estimates. While salinity normalization errors apply to nTA, nDIC, and other ions of interest in coral reefs, here, we focus on nTA due to its application as a proxy for net coral reef calcification and the importance for …

Inhibition Of Bruton Tyrosine Kinase Reduces Neuroimmune Cascade And Promotes Recovery After Spinal Cord Injury, Chen Guang Yu, Vimala Bondada, Hina Iqbal, Kate L. Moore, John C. Gensel, Subbarao Bondada, James W. Geddes

Physiology Faculty Publications

Microglia/astrocyte and B cell neuroimmune responses are major contributors to the neurological deficits after traumatic spinal cord injury (SCI). Bruton tyrosine kinase (BTK) activation mechanistically links these neuroimmune mechanisms. Our objective is to use Ibrutinib, an FDA-approved BTK inhibitor, to inhibit the neuroimmune cascade thereby improving locomotor recovery after SCI. Rat models of contusive SCI, Western blot, immunofluorescence staining imaging, flow cytometry analysis, histological staining, and behavioral assessment were used to evaluate BTK activity, neuroimmune cascades, and functional outcomes. Both BTK expression and phosphorylation were increased at the lesion site at 2, 7, 14, and 28 days after SCI. Ibrutinib …


The Utilization Of Enzymes And Enzyme Products For Antimicrobial Effects, Brandon Edward Burdette Dec 2021

The Utilization Of Enzymes And Enzyme Products For Antimicrobial Effects, Brandon Edward Burdette

Theses and Dissertations

Bacterial resistance is outpacing the discovery of novel antimicrobials. Therefore, it is essential to look at antimicrobials using novel methods. MTAN is a crucial enzyme for some bacteria such as Helicobacter pylori. Transition state analog inhibitor design and fragment-based drug design are drug design approaches typically used independently, but combining these techniques yields inhibitors that bind tightly and are effective in pM concentrations. We demonstrate the efficacy of the combined techniques by investigating the inhibition of HpMTAN, which is an essential enzyme. Enzyme byproducts can also be effective for causing bacterial cell death, hydrolyzing GsdmD by caspases-1/4/5/11 results in an …
