Mechanism of Action of Hydroxychloroquine as an Antirheumatic Drug

Mechanism of Action of Hydroxychloroquine as an Antirheumatic Drug Abstract The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis and systemic lupus erythematosus. These compounds lead to improvement of clinical and laboratory parameters, but their slow onset of action distinguishes them from glucocorticoids and nonsteroidal antiinflammatory agents. Chloroquine and hydroxychloroquine increase pH within intracellular vacuoles and alter processes such as protein degradation by acidic hydrolases in the lysosome, assembly of macromolecules in the endosomes, and posttranslation modification of proteins in the Golgi apparatus. It is proposed that the antirheumatic properties of these compounds results from their interference with "antigen processing" in macrophages and other antigen-presenting cells. Acidic cytoplasmic compartments are required for the antigenic protein to be digested and for the pept

Navigating the Climate Crisis: Understanding Climate Change and Environmental Sustainability

  Introduction: In recent years, the discourse surrounding climate change and environmental sustainability has reached a critical juncture. With scientific consensus confirming the reality of climate change and its far-reaching consequences, the urgency to take action has never been greater. In this article, we delve into the intricacies of climate change, explore its impact on the environment and society, and discuss strategies for mitigating its effects and fostering sustainability. Understanding Climate Change: At its core, climate change refers to long-term shifts in global or regional climate patterns. While variations in climate are natural phenomena, human activities, particularly the burning of fossil fuels and deforestation, have significantly accelerated the pace of climate change. The emission of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) traps heat in the Earth's atmosphere, leading to global warming and alterations in weather

Virulence Meets Metabolism: The Unique Evolution of Staphylococcus aureus

Staphylococcus blogger vinod Kumar ☝ Staphylococcus aureus (Staph) is a versatile pathogen that infects many areas of the body and has a number of strategies for avoiding the immune response. In this episode, Niki Spahich from The Scientist’s Creative Services Team spoke with Anthony Richardson, an associate professor of microbiology and molecular genetics at the University of Pittsburgh, to learn how the bacterium fine-tunes its metabolism to survive in the host and why Staph’s metabolism makes it especially dangerous for people with diabetes. The Scientist Speaks is a podcast produced by The Scientist’s Creative Services Team. Our podcast is by scientists and for scientists. Once a month, we bring you the stories behind news-worthy molecular biology research. This month's episode is sponsored by Sartorius.

HAZARD ANALYSIS AND CRITICAL CONTROL POINT (HACCP) SYSTEM AND GUIDELINES FOR ITS APPLICATION. And All HACCP concept And Conclusion

All Concept of HACCP PREAMBLE The first section of this document sets out the principles of the Hazard Analysis and Critical Control Point (HACCP) system adopted by the Codex Alimentarius Commission. The second section provides general guidance for the application of the system while recognizing that the details of application may vary depending on the circumstances of the food operation The HACCP system, which is science based and systematic, identifies specific hazards and measures for their control to ensure the safety of food. HACCP is a tool to assess hazards and establish control systems that focus on prevention rather than relying mainly on end-product testing. Any HACCP system is capable of accommodating change, such as advances in equipment design, processing procedures or technological developments. HACCP can be applied throughout the food chain from primary production to final consumption and its implementation should be guided by scientific evidence of risks to human health

Sugar pateint avoid this fruit because these fruits could be increase sugar levels

You can eat fruits—but some are higher in sugar than health experts would prefer. Here's our quick list of fruits for diabetics to avoid.   Pineapple You can tell when biting into a juicy piece of pineapple that it’s probably high in sugar. That sweet, sticky juice running down your chin contains about 16 grams of sugar per cup. You can cut back on the serving size by topping a yogurt parfait with diced pineapple.   Sweetened Cranberries Real cranberries are low in sugar and contain only 4 grams in an entire cup. However, once you dry them out and add sweetener, they’re no longer a healthy choice for people with diabetes. Rather than having dried cranberries on their own, use a small handful as a topping for oatmeal or   Raisins While raisins are an easy snack on-the-go, they’re not the best choice if you’re watching your blood sugar. According to the health experts people with diabetes should limit their fruit portions to 15 grams of carbohydrates. One cup of raisins contains 115
