Increased expression of Nppc and Npr2 in ovarian tissues from mice with polycystic ovary syndrome

Weight loss is an efficient therapy for obese polycystic ovary syndrome (PCOS) patients. Here we evaluate the effect of dietary weight reduction on clinical performance in obese PCOS patients. Medical records of fifty obese PCOS patients (age 27 ± 5 years) who had calorie-controlled dietary intervention were reviewed. The patients had a 1200-kcal/day diet until ovulation or for up to three months. Changes in body weight, body mass index (BMI), blood pressure, menstruation, acne, and hirsutusm, serum levels of endocrine hormones and adipocytokines, glucolipid metabolism index and insulin resistance were assessed. Menstrual cycle, ovulation andrelapse in the following six months were also reviewed. All patients had menstrual disorder, 43 had acne, and 26 were hirsute. After weight loss, the BMI decreased from 27.89 ± 3.06 to 25.70 ± 2.42 kg/m2 (p < 0.001). Acne and hirsutusm was improved in 39 and 14 patients, respectively. Regular menstruation was restored in 26 patients and lasted for 3.12 months on average. Endocrine hormones levels, adipocytokines levels, glucolipid metabolism and insulin resistance were shifted toward balance. Weight relapse was seen in 11 patients. No side effects occurred. Dietary intervention in obese PCOS patients can improve relevant clinical problems but weight relapse is an issue

Evaluating the Economic Performance of Reverse Polymerization Technology for Waste Tyre Recycling in Sub-Saharan Africa

The unlawful and uncontrolled disposal of waste tyres is greatly disturbing in terms of the environmental concerns and the economic misfortune. In combating this menace, there is growing interest in the application of efficient and environmental-friendly alternatives to the traditional recycling methods for waste tyres. Pyrolysis can be considered as an appropriate non-conventional method for complex materials such as tyres. Several works have been made to improve pyrolysis process towards higher yield and quality of biofuels and greater energy efficiency. This study considers Reverse Polymerization, a microwave-assisted pyrolysis process to extract complete yield and higher quality of valuable products, while avoiding toxic emissions into the environment. The feasibility of such innovative recycling process in Sub-Sahara Africa is essential in order to convince concerned authorities to buy into such advanced technologies with great benefits. The investment analysis and economic performance indicators from the study demonstrated that the operation of such proposed recycling system in the continent is economically feasible. However, the operation of such facility under the present market conditions might highly be challenged by high investment risk as the project is highly capital intensive.

Sedoanalgesia During Dental Treatment of a Patient with Sanfilippo Syndrome: A Case Report

Sanfilippo syndrome, a type of mucopolysaccharidosis (MPS), is an autosomal recessive lysosomal storage disease. The disorder is characterized by bone abnormalities (i.e. abnormally long arms and legs when compared with the trunk length), as well as abnormal bone shapes and skin thickening.In general, patients with Sanfilippo syndrome have sharp and coarse facial features, thickening of the lips and enlargement of the mouth and tongue. Hypoplasia of hard dental tissue is also present. The parents of a 5-year-old female patient were referred to Konya Oral and Dental Health Hospital because of tooth pain. A full dental examination could not be conducted because the patient was not cooperative. Thus, we decided to perform the patient’s treatment under general anaesthesia. As the patient had a history of difficult intubation and the planned dental procedures could be completed in a short time, under sedoanalgesia.

Barycentric Coordinates for Polycons

This discussion is limited to two-space although much of the analysis has been generalized to higher dimensions. Barycentric coordinates are needed in some applications for polygons with concave vertices. Such elements do not have rational barycentrics and mean-value coordinates (Floater, 2003) [1] are widely used.

Polycyclic Aromatic Hydrocarbons Separation from Oil-Contaminated Soil Using Supercritical and Subcritical Water

Finding an environmental-friend and an affordable method to remove contaminated soils from polycyclic aromatic hydrocarbons (PAHs) is now an attractive field for researchers. PAHs are slightly soluble, thus hardly dissolve in organic compounds, and also biological and chemical degradation processes are not effective to remove them, and the process of extracting these pollutants from soil is a complex process. Super-critical fluid extraction is an innovative process in the field of contaminated soil treatment. Extraction with super-critical fluid is a simple and rapid extraction process which uses supercritical fluids as solvents. This method addresses extraction methods using supercritical and subcritical fluid. The results showed that the supercritical fluid process is very suitable to remove the pollutants such as PHCs, PAHs, PCBs, dioxins, Furans, phenols, Chlorophenols, insecticides, metals and radioactive substances. The supercritical fluid extraction using CO2 also has the ability to effectively eliminate organic and inorganic compounds present in different contaminated soils. Moreover, this method is more economical for polluted soil treatment compared to other available methods. On the other hand, using this method that uses water is environment-friendly and has lower cost and a higher safety level. Research has also shown that pressurized hot water extraction (SWE) is a better way to extract PAHs. In this method, the extraction process can be improved by combining the SWE process with the oxidation process by adding oxidants such as air, oxygen, hydrogen peroxide, etc.

Gene Therapy in Sickle Cell Disease

Sickle cell disease is a prevalent and severe monogenic disorder resulting from a homozygous missense mutation in the β-globin gene that leads to polymerization of hemoglobin S. Clinical manifestations of the disease can be critical with considerable morbidity and mortality. One treatment option for the disease is bone marrow transplantation. However this method is restricted to the patients with an appropriately matched donor. Gene therapy by either gene insertion or gene editing, utilizing patient’s own cell is a primary therapeutic option to cure sickle cell disease. However, very less clinical trials have been performed with genetic therapy for treating Sickle cell disease (SCD). Since a couple of decades significant progress has been made in the area of gene therapy for treating monogenic hemoglobin disorders. Numerous therapies are currently in clinical trial stages or in preclinical stages. The safety and efficacy of gene therapy has been greatly improved with the initial use of γ-retrovirus vectors, followed by next-generation lentivirus vectors, and latest gene editing techniques. Although the clinical interpretation of gene therapy has been successful, it involves some limitations including complex cellular abnormalities, inadequate transgene expression, and challenges in achieving effective and persistent inhibition of polymerization of hemoglobin S. This review intends to discuss gene therapy strategies specific to Sickle cell disease, present state of the field, and current status of the gene therapy clinical trials.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
