Evaluation of Oxidative Status of Gout Patients in Cameroon

Gout, one of the most painful form of inflammatory arthritis, is characterized by sudden, severe attacks of pain, redness and tenderness in joints, often the joint at the base of the big toe. It’s reported that gout is one of the most frequently referenced medical disorders in the history of mankind and its cases have increased in recent years because of an aging population, the rise in obesity, increasing numbers of people who also have other conditions such as heart disease, kidney disease, and/or diabetes. And it’s the result of too much uric acid in the blood, which is called hyperuricemia.

According to some literature, it has been proved that hyperuricemia is associated to the development of high blood pressure, type II diabetes, chronic kidney disease, cardiovascular and cerebrovascular events and it seems that this relationship is based on oxidative stress, which is essentially an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants.

In this paper, to know about the relationship between these diseases and hyperuricemia, the authors conducted a case-control study from the 4th January to the 4th May 2016 at the Rheumatology service of the Yaoundé Central Hospital and aimed to determine the oxidative status of patients with gout attack. They first collected 60 samples and the average age of gout patients was 58 ± 8 years old that of the controls was 57.6 ± 8 years old; then carried out basic physical examination and collected blood samples; next they conducted biochemical analysis and statistical analysis. 

The findings indicated that people affected by gout had over 50 years old (90%) and the most represented age group was 50 to 60 years old (53%); the average uricemia of cases (81 ± 20 mg/L) was statistically higher than that of the controls; the malondialdehyde (MDA) levels were higher among cases (1.37 ± 0.46 mmol/L) compared to controls (1.14 ± 0.39 mmol/L); and there was no significant difference in serum levels of catalase, superoxide dismutase (SOD) and glutathione peroxidase (GPx) between cases and controls. SOD, GPx, MDA and catalase are markers of oxidative stress.

In conclusion, patients with acute gout have an elevated serum level of malondialdehyde, but their oxidative status seems similar to that of normal individuals.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Evaluation of the Safety and Efficacy of Continuous Use of a Home-Use High-Frequency Facial Treatment Appliance

At present, many home-use beauty devices are available in the market. In particular, many products developed for facial treatment use light, e.g., a flash lamp or a light-emitting diode (LED). In this study, the safety of 4 weeks’ continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin.  Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Fur...
