BACKGROUND: Several medicinal properties have been reported for plants in the genus Evolvulus, such as a brain tonic and antifungal from Evolvulus alsinoides, and a sedative and an anthelmintic from Evolvulus nummularius. Therefore, the correct identification of the source plants is critically important. The aim of this research was to investigate the micromorphology of two Evolvulus taxa used for herbal medicines compared with one worldwide ornamental species by using peeling, paraffin embedding, acetolysis, and SEM methods in order to support species identification...

Radix Bupleuri (Chaihu) has been used as a traditional medicine for more than 2000 years in China, Japan, Korea, and other Asian countries. Phytochemical studies demonstrated that this plant contains essential oils, triterpenoid saponins, polyacetylenes, flavonoids, lignans, fatty acids, and sterols. Crude extracts and pure compounds isolated from Radix Bupleuri exhibited various biological activities, such as anti-inflammatory, anticancer, antipyretic, antimicrobial, antiviral, hepatoprotective, neuroprotective, and immunomodulatory effects...

James L Gutmann
The use of microscopes in dentistry has become quite popular since the late 1980s. However, its origin for dental applications can be traced to the early 20th century, when a microscope, invented by an American biologist named Greenough, working in the Zeiss Company, was adapted for use in dentistry. Initially it had been used in botany, metallurgy, and zoology, in addition to revolutionizing the study of coral and entomology.

In tests of object recognition, individual differences typically correlate modestly but nontrivially across familiar categories (e.g. cars, faces, shoes, birds, mushrooms). In theory, these correlations could reflect either global, non-specific mechanisms, such as general intelligence (IQ), or more specific mechanisms. Here, we introduce two separate methods for effectively capturing category-general performance variation, one that uses novel objects and one that uses familiar objects. In each case, we show that category-general performance variance is unrelated to IQ, thereby implicating more specific mechanisms...

Matthew Holmes
Modern methods of analysing biological materials, including protein and DNA sequencing, are increasingly the objects of historical study. Yet twentieth-century taxonomic techniques have been overlooked in one of their most important contexts: agricultural botany. This paper addresses this omission by harnessing unexamined archival material from the National Institute of Agricultural Botany (NIAB), a British plant science organization. During the 1980s the NIAB carried out three overlapping research programmes in crop identification and analysis: electrophoresis, near infrared spectroscopy (NIRS) and machine vision systems...

María Jesús Santesmases
This essay presents the early days of human cytogenetics, from the late 1950s until the mid 1970s, as a historical series of images. I propose a chronology moving from photographs of bodies to chromosome sets, to be joined by ultrasound images, which provided a return to bodies, by then focused on the unborn. Images carried ontological significance and, as I will argue, are principal characters in the history of human cytogenetics. Inspired by the historiography of heredity and genetics, studies on visual cultures, the conceptualization of circulation, and the sociology of pregnancy, I suggest that cytogenetics, through its focus on pregnancy, pregnant women, and their offspring, found strategic living materials that stabilized human chromosome studies as a biomedical, post-eugenics practice...

Islam and its followers had created a civilization that played very important role on the world stage for more than a thousand years. One of the most important specific qualities of the Islamic civilization is that it is a well-balanced civilization that brought together science and faith, struck a balance between spirit and matter and did not separate this world from the Hereafter. This is what distinguishes the Islamic civilization from other civilizations which attach primary importance to the material aspect of life, physical needs and human instincts, and attach greater attention to this world by striving to instantly satisfy desires of the flesh, without finding a proper place for God and the Hereafter in their philosophies and education systems...

The purpose of this historical review is to summarize the work of the Dutch physician, chemist and anatomist Gerard Blaes (Blasius). A detailed account of his life and work is presented with emphasis on his contribution to anatomy. In particular, special reference is made to his innovative description of the spinal cord and spinal nerves. The contribution of Gerard Blasius to neuroanatomy was remarkable when taking into account the limited technology and lack of modern devices of his era. As a true man of his era, he had a significant contribution in research and teaching of anatomy, botany and chemistry...

The meeting of the Lenin All-Union Academy of Agricultural Sciences (VASKhNIL) that occurred from July 31 to August 7, 1948, declared Michurinism to be the only "correct theory" of biology in the Soviet Union. As of that moment, Michurinist biology officially took center stage in Soviet scientific institutions, and it was further developed over the next fifteen years. Scientists from all of the former Soviet Republics participated in the Michurinist campaign. In Lithuania, this campaign started in the autumn of 1948...

Natural products are an interesting source of new therapeutics, especially for cancer therapy as 70% of them have botany origin. Propolis, a resinous mixture that honey bees collect and transform from tree buds, sap flows, or other botanical sources, has been used by ethnobotany and traditional practitioners as early in Egypt as 3000 BCE. Enriched in flavonoids, phenol acids and terpene derivatives, propolis has been widely used for its antibacterial, antifungal and anti-inflammatory properties. Even though it is a challenge to standardize propolis composition, chemical analyses have pointed out interesting molecules that also present anti-oxidant and anti-proliferative properties that are of interest in the field of anti-cancer therapy...

Exogenous short biologically active peptides epitalon (Ala-Glu-Asp-Gly), bronchogen (Ala-Glu-Asp-Leu), and vilon (Lys-Glu) at concentrations 10(-7)-10(-9) M significantly influence growth, development, and differentiation of tobacco (Nicotiana tabacum) callus cultures. Epitalon and bronchogen, in particular, both increase growth of calluses and stimulate formation and growth of leaves in plant regenerants. Because the regulatory activity of the short peptides appears at low peptide concentrations, their action to some extent is like that of the activity of phytohormones, and it seems to have signaling character and epigenetic nature...

Food poisoning is frequently caused by the accidental ingestion of toxic plants that possess strong morphological similarities to edible plants. False helleborine (Veratrum album) is one of the most common plants involved in such accidents. In cases of poisoning by toxic plants, rapid and accurate identification, usually based on the morphological or chemical analysis of plant parts, is required for appropriate medical treatment or forensic investigation. However, morphological examinations require experience in systematic botany because the samples are fragmentary, and chemical analysis of natural compounds can be difficult...

ETHNOPHARMACOLOGICAL RELEVANCE: It is not always possible to correlate the "emic" terms to the "etic" ones during ethnopharmacological surveys, especially regarding those related to Culture-Bound Syndromes (CBS). Nevertheless, it is the role of ethnopharmacology to address these correlations, since they are the basis for the understanding of potential bioactives. AIM AND OBJECTIVES: This study reports the clinical manifestations and therapeutic resources used for the treatment of CBS among some riverine inhabitants of Brazilian Amazonia...
