ЧЕЙН, ЭРНСТ БОРИС
(Chain, Ernst Boris) (1906-1979), английский биохимик, удостоенный в 1945 Нобелевской премии по физиологии и медицине (совместно с А.Флемингом и Х.Флори) за открытие и синтез пенициллина. Родился 19 июня 1906 в Берлине. Окончил университет Фридриха Вильгельма в Берлине, где в 1930 получил степень доктора. В 1930-1933 работал на кафедре химии Института патологии в Берлине. В 1933 эмигрировал в Англию. В 1933-1935 работал в Кембриджском университете под руководством Ф.Хопкинса, с 1935 вел практикум и читал лекции в Оксфордском университете; впоследствии стал профессором этого университета. С 1948 по 1961 - директор Международного центра химической микробиологии в Риме (с 1950 - профессор биохимии там же). С 1961 - профессор биохимии Лондонского университета; оставил этот пост в 1973.
Основная область научных исследований Чейна - биохимия антибиотиков. В 1940 он совместно с Х.Флори выделил из культуры плесневого гриба пенициллин, изучил его химические свойства и структуру. В 1941 впервые применил пенициллин для лечения человека. В 1940 обнаружил, что некоторые бактерии продуцируют фермент пенициллиназу, повышающий их устойчивость к пенициллину. Изучил механизм действия лизоцима, исследовал процессы метаболизма в опухолевой ткани. Разработал методы биохимического микроанализа, технологию некоторых микробиологических производств. Чейн был награжден медалью И.Берцелиуса (1946), медалью Л.Пастера, удостоен премии П.Эрлиха (1954). Умер Чейн в Ирландии 14 августа 1979.

Tongs

Tongs are a type of tool used to grip and lift objects instead of holding them directly with hands. There are many forms of tongs adapted to their specific use.

The first pair of tongs belongs to the Egyptians. Tongs likely started off as basic wooden tongs and then over time progressed to bronze bars as early as 3000BC. Over time they progressed to what are now known as modern-day tongs.

An Egyptian wall painting from 1450 BCE shows a crucible supported between two metal bars. The same painting shows someone holding a small object over a fire with a tong-like instrument. Bronze loops capable of handling heavy crucibles also happened to appear at this time.

  1. Tongs that have long arms terminating in small flat circular ends of tongs and are pivoted at a joint close to the handle used to handle delicate objects. Common fire-tongs, used for picking up pieces of coal and placing them on a fire without burning fingers or getting them dirty are of this type. Tongs for grilling, tongs for serving salad or spaghetti are kitchen utensils of the same type. They provide a way to move, rotate and turn the food with delicate precision, or fetch a full serving in one grab.
  2. Tongs consisting of a single band of bent metal, as in sugar tongs, most asparagus tongs (which are no longer common) and the like. Sugar tongs are usually silver, with claw-shaped or spoon-shaped ends for serving lump sugar. Asparagus tongs are usually similar but larger, with a band near the head that limits how far the tongs can expand. Asparagus tongs for serving were introduced in 18th-century England, with smaller versions for eating asparagus appearing in the 19th century.
  3. Tongs in which the pivot or joint is placed close to the gripping ends are used to handle hard and heavy objects. Driller's round tongs, blacksmith's tongs or crucible tongs are of this type.

Design variations include resting points so that the working end of the tongs does not come into contact with a bench surface.

A myth contained in the classical Jewish text Pirkei Avot states that the first pair of tongs were created by God right before God rested on the Seventh Day. The reasoning is that a blacksmith must use a pair of tongs in order to fashion a new pair of tongs. Accordingly, God must have provided humankind with the first pair of tongs.
