Anatomical analysis of the radial nerve and arcade of Frohse in the cubital fossa using human cadavers.

BACKGROUND: The radial nerve (RN) is a peripheral nerve that originates from the posterior bundle of the brachial plexus and carries C5-Th1 fibers. In the cubital fossa radial nerve divides into a superficial branch of the radial nerve (SBRN) and a deep branch of the radial nerve (DBRN). Next DBRN enters under the arcade of Frohse (AF) and changes its name to posterior interosseous nerve of antebrachii (PIN). The AF was first described in 1908 by Frohs and Frankel. It is the superior proximal part of the supinator muscle, which can be tendinous or membranous. MATERIALS AND METHODS: Eight dissected upper limbs were examined to measure the distances and characteristics of the RN, DBRN, SBRN and AF, utilizing precise electronic caliper. RESULTS: The average distance from the point of branching of the RN into its terminal branches to the AF was 54.64 mm on average. In half of the cases DBRN divided before entering the AF. The average distance from the point of branching of the DBRN to the AF in these cases was 13.88 mm. The width of the AF averaged 8.60 mm. Five tendinous AF and three membranous AF were identified. CONCLUSIONS: A thorough understanding of the anatomy of the radial nerve and its branches in the cubital fossa, as well as the AF, is important for the development of anatomy and may also contribute to the reduction of surgical complications during procedures in this area.

Kazimierz Funk: Polish vitamins' discoverer. / Kazimierz Funk - polski odkrywca witamin.

Kazimierz Funk, born on February 23, 1884, in Warsaw, demonstrated an early inclination toward the field of human physiology. He charted his scientific trajectory within esteemed European scientific institutions, commencing at the age of 16 in Geneva, where he pursued studies in natural sciences. Subsequently, he continued his academic endeavors in Bern, culminating in the attainment of his doctorate in 1904. Following this, Funk relocated to Paris and secured a position at the Pasteur Institute. In France, his research concentrated on elucidating the role of trace elements in the human body. In 1906 he transitioned to Berlin, collaborating with Hermann Fisher (1852-1919) to investigate proteins and cancer processes. In 1910, Funk ventured to London, joining the Lister Institute, where he initiated research on beriberi disease. His investigations led to the isolation of a substance pivotal in treating the ailment, which he termed "vitamin" (derived from 'vita' meaning life and 'amine' indicating a nitrogen-containing compound). Despite four nominations for the Nobel Prize (in 1914, 1925, 1926, and 1946), Kazimierz Funk didn't receive the prestigious accolade. In 1925, at the urging of Dr. Ludwik Rajchman (1881-1965), the director of the National Institute of Hygiene, Funk assumed the directorship of the Biochemistry and Hygiene of Nutrition Branch at the National School of Hygiene. Under Funk's guidance, Poland became the third European country to produce insulin. Kazimierz Funk passed away on November 19, 1967, in New York City, at the age of 83. His significant contributions to the fields of biochemistry and nutrition endure as a testament to his enduring impact on scientific understanding. This proposal aims to condense and emphasise Kazimierz Funk's diverse scientific interests and the various scientific teams and sites he collaborated with, which ultimately led to his groundbreaking discover.

Study of social awareness regarding body donations for scientific and educational purposes.

BACKGROUND: The basis of teaching anatomy is the understanding of the body's structures using human cadavers. Body donation should be a fully conscious and voluntary act. There is a growing demand for human cadavers in medical universities. To meet these demands, it is necessary to understand the societal awareness regarding body donation. MATERIALS AND METHODS: The study utilized a proprietary single-choice questionnaire while maintaining the anonymity of the respondents. The study included 1004 individuals, comprising 700 women and 304 men. The analysis employed the Mann-Whitney test, Pearson's chi-squared test with calculation of the Cramer's V coefficient. RESULTS: Among the respondents, 56.37% consider donating their bodies for scientific and educational purposes. Among the concerns associated with donation, fear of lack of proper respect for the remains by students (18.23%), family opposition (16.24%), and religious reasons (9.16%) were highlighted. Non-religious individuals are more inclined to donate their bodies for scientific and educational purposes than religious individuals (p < 0.001). Residents of rural areas and small towns are less likely to consider donating their bodies for scientific and educational purposes than residents of large cities (p = 0.002). As many as 85.76% of respondents believe that human remains are essential for effective anatomy education. CONCLUSIONS: Increasing public awareness of cadaver donation may contribute to increasing the effectiveness of anatomy teaching at medical universities.

Sir Frederick Grant Banting - the discoverer of insulin. On the 100th anniversary on the Nobel Prize.

Over the past thousands of years, diabetes has deprived people all over the world of their lives. Until 1922, mankind remained powerless. However, change came, with Frederick Banting (1891-1941), the discoverer of insulin. This breakthrough discovery was made not by a great scientist, but by a hard-working and persistent doctor. Perhaps Banting's conscientiousness and integrity stemmed from where he grew up? A small farm in the provinces certainly influenced his further development. A development that was not obvious, because as a child little Freddie had learning difficulties. Determination led him to medicine. It must not have been without surprise to Professor MacLeod (1876-1935) when, in his office at the University of Ontario, he heard from the 30-year-old doctor that he had an idea on how to save lives from an incurable disease. The opportunity Banting was given, he used effectively. Together with the help of his student Charles Best (1899-1978), he isolated insulin. The dissemination of insulin in Poland was very quickly taken up by Kazimierz Funk (1884-1967), the discoverer of thiamine and creator of the term 'vitamin'. As head of the Department of Biochemistry at the National Institute of Hygiene (PZH), he began producing insulin from bovine pancreases in 1924. He carried out this initiative using his private funds, equipping the laboratory with the appropriate equipment. Banting's remarkable feat was rewarded in 1923. Nobel Prize, which he shared with MacLeod. The fact that the actual co-discoverer of insulin, Charles Best, was not included in the award outraged Banting to such an extent that he decided not to accept the prize. After much persuasion, he changed his mind, but shared the financial reward with his faithful assistant. The discoverer's determination and behaviour in the face of success provides an invaluable lesson for today's doctors and scientists. By following the principles Banting espoused, we can honour his memory.
