Acromegaly has been associated with several metabolic health conditions that can increase risks of death and illness. These include heart disease, diabetes, and problems with how the body regulates insulin levels. Multiple studies have found that people living with acromegaly are two to four times more likely to pass away than others of the same age and sex in the general population. Research also suggests a link between acromegaly and higher levels of malondialdehyde (MDA) in the body. MDA is a byproduct formed during natural processes like prostaglandin and lipid peroxidation production that is able to damage genes and has been connected to cancer development. The transmembrane protein known as soluble a-Klotho (SAKL) is named after a Greek deity. Numerous age-related illnesses, including osteoporosis, pulmonary emphysema, skin shrinkage, and atherosclerosis, have been shown to affect α -Klotho-deficient mice. Sixty subjects (30 males and 30 female) Mean ± SD was (53.2±10.5). diagnosed with acromegaly and 30 (15 males and 15 female) healthy group Mean ±SD was (52.1±13.5). the age range between (30-60) years. Laboratory measurement including serum Insulin like growth factor-1 (IGF-1), Growth hormone (GH) Fasting serum glucose (FSG), lipid profile (Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), Very Low-Density Lipoprotein (VLDL)), Soluble a-Klotho (SAKL), Malondialdehyde (MDA). The results showed significantly higher P ≤ 0.01 IGF1, GH, FSG, TC, TG, LDL, VLDL, SAKL, and MDA levels in patients’ group Compared to healthy group. In patients’ group SAKL had a positive significant correlation with HDL, and negative significant correlation (P ˂ 0.01) with LDL, on the other hand, there was a substantial relationship P ˂ 0.01 between (TC, TG, and LDL) with MDA. The research findings suggest that levels of SAKL and MDA are increased in patients with acromegaly, potentially serving as novel biomarkers for assessing active acromegaly. The measurement of SAKL and MDA could prove valuable, particularly in cases where GH and IGF-I results are inconclusive or conflicting
Eco-friendly concrete is produced using the waste of many industries. It reduces the fears concerning energy utilization, raw materials, and mass-produced cost of common concrete. Several stress-strain models documented in the literature can be utilized to estimate the ultimate strength of concrete components reinforced with fibers. Unfortunately, there is a lack of data on how non-metallic fibers, such as polypropylene (PP), affect the properties of concrete, especially eco-friendly concrete. This study presents a novel approach to modeling the stress-strain behavior of eco-friendly polypropylene fiber-reinforced concrete (PFRC) using meta-heuristic particle swarm optimization (PSO) employing 26 PFRC various mixtures. The cement was partia

Sufficient conditions that ensure the appearance of local and Hopf bifurcation of the system have been achieved, and it’s observed that near the free predator, the free second prey and the free first prey equilibrium points there are transcritical or pitchfork and no saddle node. While near the coexistence equilibrium point there is transcritical, pitchfork and saddle node bifurcation. For the Hopf bifurcation near the coexistence equilibrium point have been studied. Further, numerical analysis has been used to validate the main results.
The effect of molecules intersystem crossing (Kisc) on characteristics
(energy and duration) of a Passive Q- switched Laser Pulse has been
studied by mathematical description (rate equations model) for
temporal performance of which was used as a saturable absorber
material (passive switch) with laser. The study shows that the energy
and duration pulse are decreasing while the molecules intersystem
crossing into saturable absorber energy levels is increasing.
Cr2O3 thin films have been prepared by spray pyrolysis on a glass substrate. Absorbance and transmittance spectra were recorded in the wavelength range (300-900) nm before and after annealing. The effects of annealing temperature on absorption coefficient, refractive index, extinction coefficient, real and imaginary parts of dielectric constant and optical conductivity were expected. It was found that all these parameters increase as the annealing temperature increased to 550°C.
This study was undertaken to diagnose routine settling problems within a third-party oil and gas companies’ Mono-Ethylene Glycol (MEG) regeneration system. Two primary issues were identified including; a) low particle size (<40 μm) resulting in poor settlement within high viscosity MEG solution and b) exposure to hydrocarbon condensate causing modification of particle surface properties through oil-wetting of the particle surface. Analysis of oil-wetted quartz and iron carbonate (FeCO₃) settlement behavior found a greater tendency to remain suspended in the solution and be removed in the rich MEG effluent stream or to strongly float and accumulate at the liquid-vapor interface in comparison to naturally water-wetted particles. As su

Magnetic abrasive finishing (MAF) process is one of non-traditional or advanced finishing methods which is suitable for different materials and produces high quality level of surface finish where it uses magnetic force as a machining pressure. A set of experimental tests was planned according to Taguchi orthogonal array (OA) L27 (36) with three levels and six input parameters. Experimental estimation and optimization of input parameters for MAF process for stainless steel type 316 plate work piece, six input parameters including amplitude of tooth pole, and number of cycle between teeth, current, cutting speed, working gap, and finishing time, were performed by design of experiment
