Philip R. White (1901–1968)—a tribute

The groundbreaking research carried out by Philip R. White in the 1930s and 1940s played a critical early role in the development of modern plant biotechnology and the production of biotech crops. He gained instant fame and became a historical figure early in his career by becoming the first person to attain unlimited growth of cultured plant tissues. White was one of the best known and most influential figures of his generation in plant cell culture research. His tireless and lifelong efforts to promote the use of plant cell culture systems inspired a generation of scientists and stimulated much scientific activity. White was not only a brilliant and visionary scientist but also a highly principled man who spoke courageously about the great moral and political issues of his day. He was admired as much for his science as for his humanity. His belief that plant cell culture research was not well represented at national and international meetings, and his deeply held conviction that science had to be international and without borders in order to be of service to humankind led to the founding of the International Association for Plant Biotechnology in 1963, currently the largest forum for the international plant biotechnology community. This tribute honors and celebrates Philip R. White for his inspiring science, for his kind and generous mentoring of young scientists, for his advocacy of plant cell culture research and its applications, for his promotion of international scientific exchange and cooperation, and for his leadership in the founding of the International Association for Plant Biotechnology.

It reviews his career and also his major publications, including also arguments against him made by his principal critics and his responses to these. It points out the specificity of his contributions and argues for his unique importance in defining and developing the field of ethnic and race relations in British sociology during the second half of the twentieth century and into the present century. It also mentions his many contributions to public life.     

The evolutionary ideas of F. M. (Ladimir) Klacel, teacher of Gregor Mendel

Abstract: A philosopher and teacher, F. M. (Ladimir) Klacel (1808-1882), educated in what is now the Czech Republic, developed his own explanation for the origin and interaction of living organisms. Klácel, a member of the Augustinian Monastery in Brno, influenced his younger colleague, Friar Gregor Mendel, who went on to formulate concepts in heredity that are still recognized for their profound insight. A mutual interest in the natural sciences of these two friends provided a basis for their discussions of the relationship between religion, evolution, and society. Klacel's outspoken defense of his proposals caused him to lose favor with both the Church and the authorities, and he immigrated to America in 1869. His failing health and inability to communicate with the English-speaking populace, unfortunately, limited his influence in his new environs. In this paper we trace the roots of Klacel's philosophy and elucidate his incorporation of ideas from Hegel, Darwin, and others. An investigation of Klacel's recipe for a successful society reveals his belief in the universality of life and his optimistic hope for human achievement.     

Prison became second home for psychiatrist (George Scott).

Retired prison psychiatrist George Scott recalls his career working in Canada''s penal system, including his peacemaking role in a hostage-taking incident and his work with Steven Truscott. Life "inside" is dangerous for guards, inmates, staff and psychiatrists, he says, but he never regretted his decision to devote his career to studying criminal behaviour.     

Symbiogenesis: the hidden face of Constantin Merezhkowsky

Constantin Merezhkowsky is celebrated today for his theory of symbiogenesis, postulated in the early decades of the twentieth century, particularly that chloroplasts were symbiotic cyanophytes (cyanobacteria). While biologists point singularly to what they see as his heroic achievement, its neglect and subsequent rediscovery, we introduce a broader and much more complex perspective on his science, his troubled life and career. We present a view of Merezhkowsky as zoologist, anthropologist, botanist, philosopher, and novelist. We explain the genesis of his theory of the origin of chloroplasts and of nucleus and cytoplasm as symbionts, as well as his depiction of the geo-chemical context of the origins and early evolution of life on earth. We also disclose his sordid social and political activities, his eugenics and racist writings, his paedophilia, and his metaphysics. Finally, we describe the context of his elaborate suicide in 1921.     

Pavlov and integrative physiology

Ivan Petrovich Pavlov was the first physiologist to win the Nobel Prize. The Prize was given in 1904 for his research on the neural control of salivary, gastric, and pancreatic secretion. A major reason for the success and novelty of his research was the use of unanesthetized dogs surgically prepared with chronic fistulas or gastric pouches that permitted repeated experiments in the same animal for months. Pavlov invented this chronic method because of the limitations he perceived in the use of acute anesthetized animals for investigating physiological systems. By introducing the chronic method and by showing its experimental advantages, Pavlov founded modern integrative physiology. This paper reviews Pavlov's journey from his birthplace in a provincial village in Russia to Stockholm to receive the Prize. It begins with childhood influences, describes his training and mentors, summarizes the major points of his research by reviewing his book Lectures on the Work of the Digestive Glands, and discusses his views on the relationship between physiology and medicine.     

The Philosophical Origins of Mitchell's Chemiosmotic Concepts

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early in his life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the z at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology. This revised version was published online in July 2006 with corrections to the Cover Date.     

The role of routine serum testosterone testing: routine hormone analysis is not indicated as an initial screening test in the evaluation of erectile dysfunction

A 60-year-old male physician is self-referred to your office for evaluation of his erectile dysfunction, which has been worsening for 5 years. He reports his erections rarely achieve fullness for penetration, and he is unable to ejaculate. He has tried sildenafil citrate (Viagra(R); Pfizer Inc, New York, NY) with mild success in the past. He has a strong libido and feels healthy. He rarely exercises, but is on his feet most of the day at work. He has been healthy his whole life and never seeks a doctor's attention. He has no other medical problems. His only medication is a baby aspirin once a day. His physical examination, including genitalia, is normal. As part of his initial visit, should his serum testosterone level be checked by his urologist?     

Julius Wagner-Jauregg and the Legacy of Malarial Therapy for the Treatment of General Paresis of the Insane

Julius Wagner-Jauregg, a preeminent Austrian psychiatrist was awarded the Nobel Prize in Medicine in 1927 for the development of malaria therapy for the treatment of neurosyphilis, or general paresis of the insane. Despite being only one of three psychiatrists to win a Nobel Prize, he has faded from public consciousness and his name recognition pales in comparison to his contemporary and fellow Austrian, Sigmund Freud. This paper explores his contributions to the field of biological psychiatry and also touches upon reasons, such as the growing bioethics movement, his controversial affiliation with the Nazi Party, and the evolution of neurosyphilis, that explain why Wagner-Jauregg is not more widely celebrated for his contributions to the field of psychiatry, even though his malarial treatment could be considered the earliest triumph of biological psychiatry over psychoanalysis.     

Size-specific defensive structures in a horned weevil confirm a classic battle plan: avoid fights with larger opponents

A rigid sheath that extends deep into the prothorax of male Parisoschoenus expositus serves to receive the horns of opponents in battles over females. The male cannot use his own horn unless he receives his opponent's horn in his sheath. The length of a male's sheath is always approximately equal to the length of his own horns, so his body design is appropriate only for horn-locking battles with males whose horns are equal to or shorter than his own. Horn length and sheath length are dimorphic with respect to each other and to an indicator of body size. The switch points between morphs are very nearly the same for several relationships, so the different aspects of fighting morphology are tightly coordinated.     

Abraham Flexner and the development of the Yale School of Medicine. 1999

Abraham Flexner first toured the Yale University School of Medicine in preparation for his report of 1910, but it was just the beginning of his relationship with the school. While his review of Yale in his report was generally favorable, he mentioned several shortfalls that needed to be improved to make the school acceptable. Throughout the next twenty-five years, Flexner worked with Deans George Blumer and Milton C. Winternitz to improve the school's finances, infrastructure, and quality of education through his work with the Carnegie Foundation and General Education Board. Flexner has been given great accolades for his work on medical education for the country, but little mention is made of him at Yale, even though he was one of the most influential figures in the development of Yale in the last century.     

Hans Zinsser: a tale of two cultures

Hans Zinsser, president of the Society of American Bacteriologists in 1926, was known as much for his literary and textbook writing as for his scientific contributions. He was a widely known scientist and person of letters. His early interests in poetry and other forms of literature were maintained and developed during his career as a microbiologist, and his most enduring legacy is based on his writing about microbiology for a general readership as well as his reflective and philosophical autobiography.

Endocrine and developmental correlates of unilateral cryptorchidism in a wild baboon

A wild, group-living 8.5-year-old adult baboon was found to have only a single palpable testicle, the only case of cryptorchidism found among more than 200 males that we have examined. This young adult had an unusually small body size for his age, one that was comparable to that of immature males two years younger, and during maturation his body mass was increasingly small for his age. As a young adult, he also had very low testosterone concentrations, which, in combination with his small size, history of impaired growth, and the absence of any obvious scars around the scrotum, suggest that this is a case of spontaneous unilateral cryptorchidism of unknown cause rather than one of monorchidism arising from injury. Despite striking differences in his growth, adult body size, and testosterone levels, the male's cryptorchidism seemed to have relatively little effect on his social and sexual maturation in his natal group. Nonetheless, it may be related to his inability to gain entry into another group after dispersal.     

“Pharmacognosy”! What’s that? you spell it how?

In this autobiographical sketch, the author discusses the development of his interest in the biological sciences, crediting his father, his first employer, his high school science teacher, and his college pharmacognosy professor with initially shaping his career. His early work on ergot alkaloid biosynthesis and subsequently, together with students and colleagues, on the toxic constituents of basidiomycetes is detailed. This is followed by comments on his developing interest in the therapeutic utility of herbs and phytomedicinals. A concern with the beneficial use of such products stemmed largely from observations made during sabbatical leaves and frequent travel in Germany. The importance of such botanicals (not currently recognized as drugs in the United States) in our developing health-care system is emphasized. The author concludes his comments by thanking his wife, his teachers, his students, and his many colleagues and friends for their unstinting assistance and support during his entire career.     

Goethe's Morphology: Urphänomene and Aesthetic Appraisal

This paper examines the relationships betweenGoethe's morphology and his ideas on aestheticappraisal. Goethe's science of morphology was toprovide the method for making evident purephenomena [Urphänomene], for makingintuitable the necessary laws behind theperceptible forms and formation of livingnature, through a disciplined perception. Thisemphasis contrasted with contemporary studiesof generation, which focused upon hiddenformative processes. It was his views onaesthetic appraisal that informed theseepistemological precepts of his science. Hisstudy of antique artefacts convinced Goethethat these should be prototypes for all art,since they made perceptible the ideal of art,its archetypes or objective forms. His ambitionwas to eliminate the subjective elements hecontended were leading contemporary art astray.He argued that the techniques he developed forcultivating the perception of the idealexemplars of art could become a model forscience, enabling the intuition of theobjective forms of nature through a similardisciplined and cultivated perception. Thispaper also examines some of the widermotivations for the particular emphases Goethegave to his science and aesthetics, noting asimilar impulse to discipline unruly forces inhis life – in his work as an administrator forthe Weimar court and Jena University, in hisvision of an ideal German culture centred onthe aristocracy, and in his literaryproductions and biographical writings. Finallyit discusses the extent to which those unrulyelements nevertheless remained a potent anddisturbing presence in his understanding ofnature, his art and his life.     

The Context of Ecosystem Theory

Arthur George Tansley's paper “The Temporal Genetic Series as a Means of Approach to Philosophy,” published here for the first time, provides the philosophical context for the development of his ecosystem theory. His rejection of idealist reasoning, his concern with ethics, and his long standing interest in Freudian psychology as well as mechanistic reasoning comprised the intellectual underpinnings for his thinking on systems and ecosystem theory.     

Interactions among adult males and females before and after the death of the alpha male in a free-ranging troop of Japanese macaques

This report documents the social interactions among adult Japanese macaques in a free-ranging troop before and after the death of the alpha male, who died at 28 years of age after occupying his rank position for 17 years. The alpha male’s physical condition had deteriorated due to his extreme age for several months before his death. However, he maintained his alpha position. When he was attacked by the second-ranking adult male, he was rescued by the alpha female. Thereafter, whenever the second-ranking male approached him, the alpha male screamed for the alpha female’s support. The number of adult females to whom the alpha male maintained proximity during his last four months was similar to that during the same period of the previous year. Prior to his death, the alpha male was observed in close proximity to the alpha female much more frequently than was the second-ranking male. These results indicate that the alpha male maintained his position by depending on female support and particularly that of the alpha female.     

Sir William Osler revisited.

The basis of Sir William Osler''s fame is elusive to almost all and the appropriateness of such recognition is questioned by many. His many contributions as a practitioner, teacher, writer, and scientist in medicine do not adequately explain his prominence 60 years following his death. It was his participation in the covenant of medicine and the special components of that relationship that may account for his hold on his followers today.
