Analisis Risiko Kesehatan Lingkungan (Model Pengukuran Risiko Pencemaran Udara Terhadap Kesehatan)

Kesehatan. Se-dangkan risiko (risk) merupakan fungsi peluang terjadinya gangguan kesehatan dan kepara-han (severity) gangguan kesehatan oleh karena suatu bahaya.Risiko lingkungan merupakan risiko terhadap kesehatan manusia yang disebabkan oleh karena faktor lingkungan, baik lingkungan fisik, hayati maupun sosial-ekonomi-budaya. Salah satu bahaya yang berpotensi menimbulkan dampak bagi kesehatan manusia dan ling-kungan yakni bahaya kimia yang berupa keberadaan polutan di udara.Di Indonesia Analisis Risiko Kesehatan Lingkungan (ARKL) masih belum banyak dikenal dan digunakan sebagai metoda kajian dampak lingkungan terhadap kesehatan. Pa-dahal, di beberapa negara Uni Eropa, Amerika dan Australia ARKL telah menjadi proses central idea legislasi dan regulasi pengendalian dampak lingkungan. Karenanya, merupakan hal penting untuk mengenalkan metode ARKL dalam pengukuran risiko kesehatan yang dapat ditimbulkan karena faktor lingkungan khususnya pencemaran udara

Nonlinear diffusion & thermo-electric coupling in a two-variable model of cardiac action potential

This work reports the results of the theoretical investigation of nonlinear dynamics and spiral wave breakup in a generalized two-variable model of cardiac action potential accounting for thermo-electric coupling and diffusion nonlinearities. As customary in excitable media, the common Q10 and Moore factors are used to describe thermo-electric feedback in a 10-degrees range. Motivated by the porous nature of the cardiac tissue, in this study we also propose a nonlinear Fickian flux formulated by Taylor expanding the voltage dependent diffusion coefficient up to quadratic terms. A fine tuning of the diffusive parameters is performed a priori to match the conduction velocity of the equivalent cable model. The resulting combined effects are then studied by numerically simulating different stimulation protocols on a one-dimensional cable. Model features are compared in terms of action potential morphology, restitution curves, frequency spectra and spatio-temporal phase differences. Two-dimensional long-run simulations are finally performed to characterize spiral breakup during sustained fibrillation at different thermal states. Temperature and nonlinear diffusion effects are found to impact the repolarization phase of the action potential wave with non-monotone patterns and to increase the propensity of arrhythmogenesis

Pengaruh Lama Pajanan Logam Berat Kadmium (Cd) Terhadap Kadar Kalsium (Ca) Dan Kadar Fosfat Pada Tulang Tikus Putih (Rattus Novergicus)

This study aimed to analyze the long exposure to Cadmium (Cd) on the levels of calcium and phosphate bone white mice. This study uses a white rat bone exposed and unexposed Cd were 24 male rats were divided into 4 groups for 0, 2, 4 and 6 weeks. After the surgery and then measured levels of calcium and phosphate bone white mice. The results showed that there were significant differences in the levels of Ca between control and treatment groups. White rat bone Ca levels decreased respectively 118,067 mg/gram of bone; 87,267 mg/gram of bone; 39,667 mg/gram of bone and 13,067 mg/gram bone at weeks 0, 2, 4 and 6. The results of statistical tests performed by Kruskal-Wallis (p=0.000; p0.05), which means that exposure to Cd can not lower phosphate levels significantly due to the reciprocal relationship between Ca and P which resulted in secretion of parathyroid hormone so the bone does not release phosphate in the number of great. Thus concluded that exposure to heavy metals cadmium (Cd) for 6 weeks can reduce bone calcium white mice, but have not been able to reduce levels of phosphate bone white mice significantly

Mechanisms Governing 90Sr Removal and Remobilisation in a VLLW Surface Disposal Concept

Flow-through columns were used to assess potential long-term trends in 90Sr biogeochemistry and transport in a Finnish near-surface very low-level waste (VLLW) repository concept. Experiments simulated the effects of water intrusion and flow through the repository barrier and backfill materials, examining impacts on 90Sr migration. Artificial rainwater containing 2.0 mg/L stable Sr (as a proxy for 90Sr) was pumped through column systems that had varying compositions from a matrix of rock flour (backfill material), bentonite (backfill/sealing material), and carbon steel (waste encapsulation material), for 295 days. Effluent geochemistry was monitored throughout. Sr retention behaviour in all column systems was broadly similar. Sr removal from influent rainwater was marked (~95% removed) at the beginning of the experiments, and this degree of removal was maintained for 20 days. Thereafter, Sr concentrations in the effluents began to rise, reaching ~2 mg/L by 295 days. Further, 56%–67% of added Sr was retained in the repository materials over the 295-day reaction period. Analysis of the effluents indicated that colloids did not form; as such, Sr output was likely to be aqueous Sr2+. Upon completion of the experiment, solid-associated Sr distribution and speciation in the columns were assessed through column sectioning and post-mortem analyses, which encompassed the following: total acid digests, sequential extractions, and XAS analysis. The total acid digests and sequential extractions showed that Sr was evenly distributed throughout the columns and that the majority (68%–87%) of solid-associated Sr was in the exchangeable fraction (MgCl2). This suggested that a major part of the solid-phase Sr was weakly bound to the column materials via outer-sphere sorption. Interestingly, a smaller amount of Sr (7%–23%) could only be extracted by aqua regia, suggesting that a proportion of Sr may bind more strongly to the barrier materials. XAS analysis of select samples confirmed that the dominant Sr phase was sorbed to the rock flour and bentonite, but not corroded carbon steel. Columns were also subject to remobilisation experiments using artificial rain- and seawater without added Sr. While rainwater remobilised Sr slowly, high-ionic strength seawater remobilised Sr at much higher rates in the systems containing bentonite. Interestingly, Sr was well retained in the rock flour-only system following rain and seawater intrusion. Overall, the results indicate that the column materials provide reactive surfaces for Sr removal should it be released from waste packages; however, the backfill and barrier materials have limited retention capacity, and the dominant sorption interaction is relatively weak. The safety case for the shallow disposal of radioactive waste should consider the possibility of seawater intrusion and that the bentonite-bound Sr was significantly more susceptible to remobilisation following seawater, despite retaining slightly more Sr during sorption experiments

Activating transcription factor 3 is a positive regulator of human IFNG gene expression

IL-12 and IL-18 are essential for Th1 differentiation, whereas the role of IFN-α in Th1 development is less understood. In this microarray-based study, we searched for genes that are regulated by IFN-α, IL-12, or the combination of IL-12 plus IL-18 during the early differentiation of human umbilical cord blood CD4+ Th cells. Twenty-six genes were similarly regulated in response to treatment with IL-12, IFN-α, or the combination of IL-12 plus IL-18. These genes could therefore play a role in Th1 lineage decision. Transcription factor activating transcription factor (ATF) 3 was upregulated by these cytokines and selected for further study. Ectopic expression of ATF3 in CD4+ T cells enhanced the production of IFN-α, the hallmark cytokine of Th1 cells, whereas small interfering RNA knockdown of ATF3 reduced IFN-γ production. Furthermore, ATF3 formed an endogenous complex with JUN in CD4+ T cells induced to Th1. Chromatin immunoprecipitation and luciferase reporter assays showed that both ATF3 and JUN are recruited to and transactivate the IFNG promoter during early Th1 differentiation. Collectively, these data indicate that ATF3 promotes human Th1 differentiation

Genetic support for the causal role of insulin in coronary heart disease

Epidemiological studies have identified several traits associated with CHD, but few of these have been shown to be causal risk factors and thus suitable targets for treatment. Our aim was to evaluate the causal role of a large set of known CHD risk factors using single-nucleotide polymorphisms (SNPs) as instrumental variables.Peer reviewe
