Background Identifying the active ingredients from natural herbal medicines and demonstrating their potential mechanisms are key points in the traditional Chinese medicine(TCM)field.In recent years,increasing studies have focused on the effects and mechanisms of Chinese herbal formulas.Basic studies on these formulas further coincide with the theory and practical use of TCM according to the clinical experiences for thousands of years.Single compounds have specific molecular structures;therefore,their methodologies in effect and mechanism studies are similar in both Western and Eastern medicines,making them more acceptable by researchers worldwide.

Contrary to the opinion about approximation nature of a simple-iteration method, the exact solution of a system of linear algebraic equations (SLAE) in a finite number of iterations with a stationary matrix is demonstrated. We present a theorem and its proof that confirms the possibility to obtain the finite process and imposes the requirement for the matrix of SLAE. This matrix must be unipotent, i.e. all its eigenvalues to be equal to 1. An example of transformation of SLAE given analytically to the form with a unipotent matrix is presented. It is shown that splitting the unipotent matrix into identity and nilpotent ones results in Cramer’s analytical formulas in a finite number of iterations.

Objective: To describe the growth profile of breastfeeding babies following early introduction of infant formulas to improve the feeding pattern of the young infant. Methodology: This is a longitudinal descriptive study conducted in 2 medical clinics in Abidjan from 11-Jun-2013 to 15-Dec-2016 on 100 healthy newborn babies with the introduction of infant formulas before 6 months of life. The anthropometrics parameters were compared to those of WHO. Results: The exclusive breastfeeding rate was 5%. Ablactation occurred within 12 months in 95% of cases. All Infants have doubled and tripled their birth weight at 3 and 9 months respectively. The height and the head circumference at birth increased by 50% and 37% respectively at 12 months. Compared to WHO growth charts, the weight gain for the girls at 3 months was 12.4% higher and for the boys was 7.3% higher at 6 months. On the other hands, the statural gain at 12 months was 50% lower than the WHO standards while the head circumference was 37.8% and 45.5% higher than the WHO standards in boys and girls respectively. At 3 months, the prevalence of stunting was 26.1% for boys and 13.3% for girls. Lastly, at 12 months, the BMI showed 10% overweight and 19% obesity. Conclusion: Breastfeeding associated with an early introduction of infant formulas increases the risk of malnutrition of the young infant. We advise to avoid it and recommend an exclusive breastfeeding.

This study was conducted to examine the nutritional content, contamination levels, and biological effects of 3 local prepared formulas. Formula (1) contained mixed nuts;formula (2) contained moghat, honey and royal jelly, while formula (3) contained honey, fenugreek and royal jelly. Groups of albino rats (90 rats) were randomly allocated to diets of control group or 1 - 3 treatment groups. The tested diets contained 15% carbohydrate. The weight and food intake were recorded. Blood tests were conducted to determine total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, glucose, urea, creatinine, white blood cell count (WBC), red blood cell count (RBC), haemoglobin (HB), mean corpuscular volume (MCV), and haematocrit (HCT). Results showed that bacterial contamination was found in formula (1) and formula (3). Fungal contamination was detected in formula (2) and formula (3). Body weight increased significantly in the rats fed treatment formulas compared to the control group. The blood tests indicated significant increases in the levels of glucose, WBC, HCT, total cholesterol, LDL cholesterol, and triglycerides as well as a significant decrease in HDL level in the group (2) was fed formula (1) the control. In conclusion, these findings indicate that these local formulas may not be safe, and further studies are required to understand the consequences of a long-term consumption of these formulas.
