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.

Identifying Sustainable Practices for Tapping and Sap Collection from Birch Trees

Tapping and collecting sap from birch trees ( Betula , sp.) for the production of beverages and syrup is gaining increased levels of interest. Although the practice of tapping birch trees and collecting sap has been ongoing for millennia across the world, there remain some critical data needed in order to make science-based decisions about the production practices required to optimize yields and ensure sustainable outcomes are achieved in the long-term. In this study, experiments were conducted to determine two pieces of information essential to identify practices necessary to ensure tapping trees for birch sap collection were both sustainable and profitable—the selection of the time to initiate tapping birch trees to obtain maximum yields, and the volume of nonconductive wood (NCW) associated with taphole wounds in birch trees. The yields obtained from various timing treatments varied between sapflow seasons, but indicated that using test tapholes to choose the appropriate ti

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university
