The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. It is therefore not really surprising to find out that the list of contributing authors, who were awarded a Nobel Prize, is quite long: Kurt Alder, Derek H.R. Barton, George Wells Beadle, Dorothy Crowfoot-Hodgkin, Otto Diels, Hans von Euler-Chelpin, Paul Karrer, Luis Federico Leloir, Linus Pauling, Vladimir Prelog, with Walter Norman Haworth and Adolf F.J. Butenandt serving as members of the editorial board. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.
Preterm neonates remain at increased risk for adverse bilirubin-related outcomes, including acute bilirubin encephalopathy relative to term infants. Yet, most vulnerable neonates are likely to benefit from the potent anti-oxidant properties of bilirubin. Evidence-based guidelines for the management of hyperbilirubinemia in preterm infants, however, are lacking. High concentrations of unconjugated bilirubin can cause permanent neurologic damage in infants, evident through magnetic resonance imaging of chronic bilirubin encephalopathy or kernicterus. There is a growing concern that exposures to even moderate concentrations of bilirubin may lead to subtle but permanent neurodevelopmental impairment referred to as bilirubin-induced neurologic dysfunction. Our current use of phototherapy to decrease bilirubin loads and its potential photo-oxidant properties is a biological conundrum that has been questioned in the use of phototherapy for very low birth weight neonates. In this issue of Clinics in Perinatology, we provide updates on the current understanding of the biology, mechanisms of increasing bilirubin load due to hemolysis, decreased bilirubin binding capacity and glucose-6-phosphate dehydrogenase deficiency, as well as clinical strategies to operationalize the thresholds for hyperbilirubinemia interventions in preterm infants.

For more than 45 years, Avery & MacDonald’s Neonatology has been the premier text on the pathophysiology and management of both preterm and full-term neonates, trusted by neonatologists, neonatology fellows, pediatricians, neonatal nurse practitioners, and ob/gyn practitioners worldwide. Continuing the tradition of excellence established by Drs. Gordon B. Avery and Mhairi G. MacDonald, this fully revised eighth edition features three new lead editors, numerous new chapters, reorganized and updated content, and an increased focus on global neonatology.
The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin, proteins, or nucleic acids. The final sections discuss the methodology used and the fundamental processes encountered by the biomolecules described, including diagenesis, catagenesis, and metagenesis. The second contribution covers the distribution of phthalides in nature and the findings in the structural diversity, chemical reactivity, biotransformations, syntheses, and bioactivity of natural and semisynthetic phthalides.
• Explores the different groups--from research labs to the military--who were seeking how best to utilize LSD and other promising psychedelics like mescaline • Reintroduces forgotten scientists like Robert Hyde and Rosalind Heywood • Looks at the CIA’s notorious top-secret mind-control program MKUltra • Reveals how intellectuals, philosophers, artists, and mystics of the 1950s used LSD to bring ancient rites into the modern ageExploring the initial stages of psychedelic study in Europe and America, Thomas Hatsis offers a full history of the psychedelic-fueled revolution in healing and consciousness expansion that blossomed in the 1950s--the first “golden age” of psychedelic research. Revealing LSD as a “wonder child” rather than Albert Hofmann’s infamous “problem child,” the author focuses on the extensive studies with LSD that took place in the ’50s. He explores the different groups--from research labs to the military to bohemian art circles--who were seeking how best to utilize LSD and other promising psychedelics like mescaline. Sharing the details of many primary source medical reports, the author examines how doctors saw LSD as a tool to gain access to the minds of schizophrenics and thus better understand the causes of mental illness.The author also looks at how the CIA believed LSD could be turned into a powerful mind-control weapon, including a full account of the notorious top-secret program MKUltra. Reintroducing forgotten scientists like Robert Hyde, the first American to take LSD, and parapsychologist Rosalind Heywood, who believed LSD and mescaline opened doors to mystical and psychic abilities, the author also discusses how the infl uences of Central American mushroom ceremonies and peyote rites crossbred with experimental Western mysticism during the 1950s, turning LSD from a possible madness mimicker or mind weapon into a sacramental medicine. Finally, he explores how philosophers, parapsychologists, and mystics sought to use LSD to usher in a new age of human awareness.

Abstract: This book discusses the possibility that the activity of any substance that is health-promoting or health-destructive in a given concentration may reverse its role and become respectively health-destructive or health-promoting at a different concentration. The author presents numerous examples of vitamins and minerals that reverse their customary action at different concentrations. It is speculated that the reverse effect may be used to find new therapies for cancer and other diseases.
