"Polynesians" Natural Recordings by Native Speakers
People who are of ethnic Polynesian origin or descent, particularly those who inhabit the islands of Polynesia in the Pacific Ocean, including Hawaii, New Zealand, Samoa, Tahiti, Tonga, and other island groups.
Polymyxin is a type of antibiotic that is used to treat various bacterial infections. It is a group of bactericidal compounds that work by disrupting the bacterial cell membrane, ultimately causing cell death. Polymyxin is typically used to treat infections caused by Gram-negative bacteria, such as Pseudomonas aeruginosa, E. coli, and Acinetobacter baumannii.It is effective against a wide range of bacteria, including those that are resistant to other antibiotics. However, polymyxin can also have some side effects, such as nephrotoxicity (kidney damage) and neurotoxicity (nerve damage).Polymyxin is often used in combination with other antibiotics, and it is available in various forms, including topical and injectable forms. In addition to its antibacterial properties, polymyxin has also been found to have some antimicrobial properties against other types of microorganisms, such as fungi and viruses.
Polymyxins are a group of antibiotics that work by damaging the bacterial cell membrane, ultimately leading to cell lysis and death. The most common members of the polymyxin family are polymyxin B and polymyxin E (also known as colistin).Polymyxins are typically used to treat serious bacterial infections, particularly those caused by gram-negative bacteria. They are often used when other antibiotics have failed or are ineffective.The mechanism of action of polymyxins involves binding to the lipid A domain of the lipopolysaccharide outer membrane of the bacterial cell wall, causing a disruption of the cell membrane and leading to changes in membrane permeability, impaired nutrient uptake, and ultimately, cell death.Polymyxins are administered intravenously (into a vein) and are often used in intensive care settings to treat conditions such as pneumonia, sepsis, and infections of the urinary tract. However, they are associated with several side effects, including nephrotoxicity (kidney damage) and neurotoxicity. Due to these risks, their use is limited and typically reserved for severe, life-threatening infections.
A somewhat obscure word!Polyneme (plural: polynemes) refers to a long, narrow stem or peduncle that connects a fruit or an inflorescence (a cluster of flowers) to its receptacle or stalk. In botanical terms, a polyneme is a type of stalk or peduncle that supports a cluster of flowers, typically above a single point, such as in the case of umbels or panicled inflorescences.
The family of fish commonly known as threadsails or threadfins. They are found in tropical and subtropical waters around the world, and are characterized by their long, thin filaments that extend from their dorsal and anal fins.
Polynemoid refers to the resemblance or similarity between two things, often in a superficial or deceptive way. It can also imply a type of imitative or phonetic duplication, especially in linguistic or phonetic contexts.
Polyneural refers to something that is related to or consisting of multiple nerves. In neuroscience, it can describe a condition where there is damage to multiple nerves or a neural network, or it can refer to a type of axon with multiple branching fibers.
Polyneuropathy is a medical condition in which multiple peripheral nerves are damaged, leading to muscle weakness, numbness, and pain. It is a type of neuropathy, which is a broader term that refers to damage to a single peripheral nerve or multiple peripheral nerves. The damage to the nerves can be caused by various factors such as exposure to toxins, nutritional deficiencies, diabetes, autoimmune diseases, and certain medications.Symptoms of polyneuropathy can include:<em> Weakness or muscle wasting in the affected limbs</em> Numbness or tingling sensations in the hands and feet<em> Pain or burning sensations in the legs, arms, hands, or feet</em> Difficulty walking or maintaining balance<em> Changes in reflexes</em> Difficulty controlling muscles, leading to muscle spasms or crampsTreatment for polyneuropathy typically involves managing the underlying cause and symptoms. This can include medications such as antidepressants, anticonvulsants, or pain relievers to manage pain and muscle spasms. Physical therapy and exercise can also help maintain muscle strength and mobility. In some cases, surgical intervention may be necessary to repair any nerve damage.It's worth noting that polyneuropathy is a broad term that encompasses a range of conditions, and the specific symptoms and treatment can vary depending on the underlying cause and severity of the condition.
