Ageing is a complex process that affects all living organisms. Senescence is not only conceivable in multicellular organisms, but also in unicellulars. Unlike certain diseases that have specific morbidity rates, ageing is a physiological process that affects all individuals that live long enough (unaffected by i.e. predation or famine) to experience senescence.
Penelitian terkini menunjukkan bahwa Toksin Botulinum A (yang sering dikenal dengan nama dagang Botox) memiliki keunggulan signifikan dalam menangani berbagai disfungsi saluran kemih bagian bawah (Lower Urinary Tract Dysfunctions/LUTDs). Hal ini mencakup kondisi kompleks seperti sistitis interstisial, disfungsi sfingter uretra, serta gangguan peradangan kandung kemih yang selama ini sulit diata…

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applic…
Sebagai instrumen fundamental dalam seluruh proses komunikasi, tanda telah menjadi pusat penyelidikan intelektual modern melalui disiplin semiotika. Thomas A. Sebeok, salah satu pemikir paling berpengaruh dalam bidang ini, menyajikan dalam volume ini kumpulan esai yang mengeksplorasi "Doktrin Tanda-tanda"—sebuah tradisi intelektual yang berakar dari pemikiran Locke dan Peirce hingga era konte…

The amide bond represents a privileged motif in chemistry. The recent years have witnessed an explosion of interest in the development of new chemical transformations of amides. These developments cover an impressive range of catalytic N-C bond activation in electrophilic, Lewis acid, radical, and nucleophilic reaction pathways, among other transformations. Equally relevant are structural and t…
