  Global Inhalable Drugs: New Modes of Drug Delivery Provide Opportunities and Challenges The pharmaceutical industry is continuously innovating new modes of drug delivery to improve treatment options for patients. One emerging area is   delivered via devices such as nebulizers, metered-dose inhalers, and dry powder inhalers. Inhalation provides a non-invasive way to deliver drugs directly into the lungs for local or systemic treatment of conditions like asthma, COPD, and lung infections. It can also be used to deliver drugs into the bloodstream rapidly for quick relief of symptoms. Pulmonary Drug Delivery Circumvents First-Pass Metabolism When drugs are administered orally, they must pass through the liver before entering systemic circulation. This first-pass metabolism renders part of the drug ineffective as it is broken down in the liver before reaching the bloodstream. Inhalation allows drugs to bypass the liver and enter the bloodstream through the alveoli in the lungs....

  Nasometry Devices Nasometry is an objective technique for analyzing the acoustic characteristics of the voice and its nasal quality. Nasometry devices utilize specialized microphones and sensors to identify and quantify the resonance patterns in speech. By measuring nasal airflow and acoustic resonances, nasometry provides quantitative data about the balance between oral and nasal voice production. This objective data can be useful for diagnosing voice disorders, tracking progress during voice therapy, and evaluating the effectiveness of surgical interventions. How Nasometry Works Nasometry systems work by simultaneously recording the acoustic signal from the microphone as well as the nasal airflow signal from a nasal cannula or thermistor. The microphone captures the speaker's full speech waveform, while the nasal sensor detects any airflow through the nose. By comparing these two signals, the nasometer can identify periods of voiced speech and determine the nasalance score -...

  Beta Glucan What are Beta Glucans? Beta glucans are a type of fiber found in the cell walls of mushrooms, yeast, grains such as oats and barley. They are long-chain polysaccharides made up of glucose molecules. The beta glucan fibers found in mushrooms are called beta-D-glucans. Health Benefits of Beta Glucans Boost Immune Function Beta glucans are known as biological response modifiers because they work to enhance the body's natural immune defenses. When beta glucans enter the body, they are recognized by immune cells called macrophages and neutrophils. This prompts the immune cells to increase in number and strengthen their ability to identify and remove pathogens. A stronger immune response means fewer infections to deal with. Reduce Cancer Risk Several studies have linked beta glucan intake to a lowered risk of certain cancers. It is believed that beta glucans help strengthen immune cells' anti-tumor activity. They aid macrophages in detecting and destroying cancer ce...

  CRISPR and CAS In the late 1980s and early 1990s, scientists researching bacteria discovered unusual repeats of DNA segments in the microbial genomes. Further research into these repeated segments found that they played a role in the bacteria's antiviral defense systems. These repeated segments along with associated genes were dubbed "clustered regularly interspaced short palindromic repeats", also known simply as CRISPR. CRISPR works alongside a set of genes known as CRISPR-associated genes, or CAS genes. Together, the CRISPR-CAS system serves as the bacterial immune system, immune cells. It allows bacteria to remember viruses and plasmids that previously infected them so they can recognize and destroy these pathogens again. RNA from CRISPR sequences guide CAS enzymes to match and cut the DNA of the invading virus or plasmid. Breakthrough Applications and Uses in Genome Editing It wasn't until 2012 that scientists realized the tremendous potential for practical...
