Leptin is one of the
best known hormone markers for obesity. There is a limited anthropometric data in
the Gaza Strip that reveals and arouses the nutritional status among all age groups
especially adolescents aged 15 - 19 years old. The study aimed to assess the effect
of Leptin hormone, lipid profiles, Body Mass Index (BMI) and waist circumference
among secondary school age students in the Gaza Strip. Methodology: A cross sectional
study included 442 cases of teenagers aged 15 - 19 years old from governmental and
private schools in the Gaza strip. Blood samples were collected for analysis of
Leptin hormone and lipid profile and measuring waist circumference for the teenager.
Results: The mean of serum Leptin was (28.7) higher among cases than controls (28.1),
but it was statistically insignificant (P = 0.85). It was found that there is a
significant correlation between Leptin hormone and total cholesterol (Chol) (r =
0.24), high density cholesterol (HDL) (r = 0.27) and low density cholesterol (LDL)
(r = 0.16). There was no relationship between Leptin hormone and triglycerides (TG)
(r = -0.02). There was relationship between Leptin hormone and waist circumference
in both males and females (r = 0.519, 0.544), respectively. There was no statistical
significant deference noticed between Leptin hormone of obese objects and Leptin
hormone of normal BMI objects of the same age (t-test = 0.93, P = 0.85). Conclusion:
There are significant correlations between Leptin hormone and total Chol, HDL and
LDL except for TG, and there were significant relationships between Leptin hormone
and waist circumference which reflect the central obesity among males and females.
There is no association between Leptin level and BMI.
In this article,
the modified simple equation method has been extended to celebrate the exact solutions
of nonlinear partial time-space differential equations of fractional order.
Firstly, the fractional complex transformation has been implemented to convert
nonlinear partial fractional differential equations into nonlinear ordinary
differential equations. Afterwards, modified simple equation method has been
implemented, to find the exact solutions of these equations, in the sense of
modified Riemann-Liouville derivative. For applications, the exact solutions of
time-space fractional derivative Burgers’ equation and time-space fractional
derivative foam drainage equation have been discussed. Moreover, it can also be
concluded that the proposed method is easy, direct and concise as compared to
other existing methods.
