The Benefits Of Astaxanthin To Improve Pain Relief In Patients With Painful Diabetic Neuropathy: An Open-Label, Randomized Controlled Trial, Rizaldy Taslim Pinzon, Mary Rose Angelina Budi Harsana Dec 2021

The Benefits Of Astaxanthin To Improve Pain Relief In Patients With Painful Diabetic Neuropathy: An Open-Label, Randomized Controlled Trial, Rizaldy Taslim Pinzon, Mary Rose Angelina Budi Harsana

Pharmaceutical Sciences and Research

Treatment of diabetic neuropathy is still carried out by providing symptomatic therapy, which only improves ± 50% of the total symptoms felt by patients, but does not tackle the underlying causes of the disease. Astaxanthin is a potent antioxidant, anti-inflammatory, and anti-diabetic carotenoid that could be an additional treatment option. We aimed to measure the effectiveness of administering astaxanthin as an additional therapy to improve the impact of pain and discomfort experienced daily by diabetes mellitus patients with painful diabetic neuropathy. We conducted a randomized experimental study with an open label design of 36 patients who had been diagnosed with painful ...

Makara Journal of Science

We proposed a technique for improving the platinum (Pt) Schottky contact dark current of the AlN/GaN/AlN/Si(111) substrate. The AlN/GaN/AlN/ heterostructure sample was successfully grown on a silicon substrate by radio frequency molecular beam epitaxy. The high quality of the interlayer heterostructure sample was verified by transmission electron microscopy (TEM). From the TEM image, a good quality single interface layer with spacing less than 1 nm was detected. The strong significant peaks obtained by X-ray diffraction measurement indicated that the sample has a high structural quality for each grown layer. Dry oxidation and thermal annealing ...

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 ...

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 ...

Irrigation and Melioration

Investigations of the design of a combined machine equipped with an innovative casing and a leveler apron are presented, and the parameters of the leveler apron are substantiated. It was experimentally established that when the height of the drawing prism is exceeded by more than 200 mm, due to the falling of the crumbling part of the soil onto the rotor, the soil is thrown forward in the direction of the machine. Therefore, to eliminate soil waste, it is necessary either to reduce the height of the drag prism, or to increase the distance between the rotor and the leveling ...
