The Performance Operation of Zeolite as Membrane with using Laundry Waste Water



Nanofiltration membranes have a pore size of 0.001 μ which can filter waste water from low organic content until high organic content. Nanofiltration is also used for water softening, removal of micropollutants such as sewage treatment and wastewater. So it can be used for laundry wastewater treatment alternatives.

Zeolite as Membrane

Natural zeolite is a suitable material in the fabrication of membrane because it is not easy to inflate in water and easily form a suspension to coat the membrane as a support. Membrane based zeolite are alsoused widely for the separation of hydrocarbon gases, solvent dehydration, as a catalyst for chemical conversion, pollutants remediation and clean water production.

Human Suicide Study, is there an Association between Suicide and Mental Illness?



Suicide is a major causality of human mortality across the world. Yet human suicide predictions and preventions are difficult to obtain. As a result, in order to find out new ways of solving this situation, human suicide etiological/pathologic study is quite necessary. Previously, human suicide was commonly regarded as a clinical symptom rather than an aspect of human mental illness-related disease that can be traceable from biological or genetic tangible existence discoveries. In order to clarify this matter of etiological/pathologic enigma, we document some events of historic literatures, medical ways of suicide probing and different types of counteractive measurepromotions. After all, genetic/molecular clues available for suicidal linkage between pathogenesis and therapeutics will be established. From these avenues, better clinical suicide predictive systems and therapeutic managements would be invented in future.

Suicide and Mental Illness

A range of social/environmental factors can decide human suicide rates and mortalities. Unveiling the interplay between insider (humangenetics and chemical structures of drugs) and outsider (multifactorialeconomic, social, past bad habits or trauma) is the top priority. However, small-range positive data from relevant medical managements have been repeated, let alone breakthroughs on this medical field.

Effect of Leptin and Oxidative Stress in the Blood of Obese Individuals



Obesity is a multifaceted condition and represents a pandemic that needs urgent attention. Obesity, both directly and indirectly, increases the risk for a variety of disease conditions including diabetes, hypertension, liver disease, and certain cancers, which in turn, decreases the overall lifespan in both men and women. Leptin most likely indicates satietyand fullness of energy stores under physiological conditions, but obesity is characterized by hyperleptinemia and hypothalamic leptin resistance. Many studies have found association between obesity leading to oxidative stress and diabetes mellitus type 2, and many others have shown that the level of ROS increase in obesity. 

Effect of Leptin and Oxidative Stress

Glutathione is a master antioxidant cellular defense, prevent damage to the important components caused by ROS such as free radicals and peroxide. Oxidative stress is an imbalance between oxidant and antioxidant pathways that result in the accumulation of lipid oxidation products such as lipid hydro peroxides and malondialdehyde. These materials are toxic and causeincreased risk of arteriosclerosis in the blood by other lipoproteins. In addition, increased oxidative stress in adults after exercise increases, It has been shown that aerobic exercise reduces oxidative stress in obese men.

Association between Pulse Wave Velocity and the Framingham Risk Score in Patients with different Glucose Metabolism Status



By the end of 2013, diabetes had caused 5.1 million deaths and cost billions for healthcare spending. Without concerted action to prevent diabetes, there will be 592 million people living with the disease in less than 25 years’ time. CVD is the major cause of mortality and morbidity in patients with type 2 diabetes. The clinical relevance of this metabolicsyndrome is related to its role in the development of vascular disease, including endothelium impair, an increase in arterial stiffness and intima-media thickness. Diabetes mellitus and impaired fasting glucose bring carotid arterioles atherosclerosis and hence draw our attention. PWV can intelligently show the flexible degree of aorta blood vessel, and is the gold standard evaluating atherosclerosis.

Pulse Wave Velocity
The research is to investigate the relationship between different glucose metabolism status and PWVand further explore its relationship between PWV, HOMA-IR and FRS. Pre-diabetes has been first described by the WHOin 1980 as impaired glucose tolerance (IGT). In order to avoid the time-consuming and somewhat cumbersome measurement of 2h PG, the ADA proposed to identify pre-diabetes as impaired fasting glucose (IFG) in 1997, which relies on one fasting measurement only. In 2004, the ADA lowered the cutoff point for IFG from 6.1 to 5.6 mmol/l. IFG and IGT are strongly associated with excess body weight and insulin resistance, which is the central feature of the metabolic syndrome metabolic abnormalities and leads the path to diabetes.

Jasmonic Acid: Genetic Pathway, Signal Transduction and Action in Plant Development and Defence



Jasmonic acid (JA) is one of the most signaling phytohormones which play an essential role in plant development and response to biotic and abiotic stresses. It plays a key regulatory role in root elongation, pollen production, germination, fruit ripening, plant senescence. Additionally, it activates plant defenses against pests, pathogens and abiotic stress. Jasmonic acid and its derivative methyl jasmonate are abundant in plant cellsand have a physiological signaling mechanism. Recently, jasmonates have been reported to be the active forms precursors comprising certain amino acid conjugates. Jasmonates are generally synthesized and accumulated upon environmental or developmental stimuli. Jasmonate signal transduction process is regulated by a signaling mechanism embracing certain repressor proteins which control different transcription factors regulating the expression of jasmonate responsive genes.

Jasmonic Acid

The first step of JA synthesis takes place in chloroplasts membranes, where a phospholipase generates both of α-linolenic acid and hexadecatrienoic acid from membrane phospholipids. JAs synthesisoccurs generally from the α-linolenic acid precursor through the octadecanoidpathway. Chloroplastic 13-lipoxygenase oxidizes αLA forming the 13-hydroperoxy derivative of linolenic acid. The Arabidopsis genome comprises six genes encoding lipoxygenases. Three of such genes (LOX2, LOX3 and LOX4) regulate JA production. The next steps of JA synthesis occur in the peroxisome.
