The Scanning Electron Microscope (SEM) is an electron microscope that produces an image of a sample by scanning it with a focused beam of electrons. The electrons interact with the atoms in the sample, which emit secondary electrons that contain information about the surface topography and composition. The sample is scanned by the electron beam point by point, until an image of the surface is formed. Since its invention in 1942, the capabilities of SEMs have become paramount in the discovery and understanding of the nanometer world, and today it is extensively used for both research and in industry...

When two lineages derived from a common ancestor become reproductively isolated (e.g. Neurospora crassa and N. tetrasperma), genes that have undergone mutation and adaptive evolution in one lineage can potentially become dysfunctional when transferred into the other, since other genes have undergone mutation and evolution in the second lineage, and the derived alleles were never 'tested' together before hybrid formation. Bateson (1909), Dobzhansky (1936), and Muller (1942) recognized that incompatibility between the derived alleles could potentially make the hybrid lethal, sterile, or display some other detriment...

In recent years, there has been an ever growing interest in finding new natural sources of food antioxidants. As a main fruit crop, olive is also valued due to its phenolic-containing leaves. Mathematically based optimization methods are used as powerful tools to extract different antioxidant compounds. The present study is aimed to provide an efficient extraction method for total phenol content (TPC), total flavonoid content (TFC) and antioxidant ability (DPPH scavenging assay and FRAP). The effects of ultrasonic temperature (35-65 °C), ultrasonic time (5-15 min), and ethanol to water ratio (Et: W) (25-75%) were evaluated...

Laryngeal cancer was a well known entity since antiquity and its treatment evolved through several phases. The lack of knowledge in anatomy and pathology as well as the absence of anesthesia and proper instrumentation made the treatment almost impossible. Ancient physicians were performing laryngotomy or tracheotomy in an attempt to prevent the suffocation symptoms produced by tumoral masses. In 19th century the invention of laryngoscope and the advent of pathology and anesthesiology encouraged surgeons to operate on man...

AbstractMycetoma is a chronic soft tissue infection caused by fungal or bacterial pathogens, and is endemic in tropical and subtropical regions. Cases in developed countries outside the mycetoma belt are rare and usually imported by immigrants. Sporadic cases have been reported in Israel. Unpublished cases in the participating medical centers are reported. In addition, a systematic review of the literature was performed. All published mycetoma cases diagnosed in Israel were included with relevant variables collected...

A survey on the cestode fauna of Paragaleus randalli Compagno, Krupp & Carpenter in the Persian Gulf resulted in the discovery of a new trypanorhynch species of the family Otobothriidae Dollfus, 1942, the second otobothrioid species hosted by the family Hemigaleidae Hasse. The new species exhibits the closest morphological similarity to Pristiorhynchus palmi Schaeffner & Beveridge, 2013, the type- and only species of its genus. However, the new species differs from P. palmi in the position of the bothrial pits, the morphology and oncotaxy of the basal armature, the commencement of the hook files on the internal surface, a wider scolex peduncle in the pars bulbosa than in the pars vaginalis, a long neck and the presence of a lateral bothrial groove connecting the two bothrial pits to each other...

The high-ranking German Nazi Reinhard Heydrich (1904-1942) was one of the main organizers of the mass murder of Jews during the Second World War. He died on June 4, 1942, in Prague after having been wounded in Operation Anthropoid planned by the British intelligence services. Since the 1970s and 1980s, Heydrich's death has been frequently presented in British, American, and French literature as the consequence of a bacteriologic attack. Botulinum toxin would have been used in the grenades or ammunition. We discuss the botulinum toxin hypothesis using the now declassified British archives of Operation Anthropoid and of the chemical and bacteriologic warfare centers to assess this hypothesis...

Julius Hallervorden, a distinguished German neuropathologist, admitted on several occasions that he had received some five hundred brains of "euthanasia" victims from the Nazi killing centres for the insane. He investigated the brains in the summer of 1942; however, their traces were subsequently lost. The present study shows, that the Series H, which was part of the Hallervorden collection of brain sections in the Max Planck Institute for Brain Research, comprises the brain sections of the above mentioned five hundred euthanasia victims...

Rabies has no known beginning in Morocco and to date, government control efforts and plans fail to eradicate the disease. A review and analysis of available epidemiological data are crucial to learn lessons from the past and to propose effective actions. Legally, animal rabies is a notifiable disease since 1913 and legislation has been updated periodically since. Dogs have always been considered as both the disease's vector and reservoir, while cattle, other herbivores, and humans are victims. Animal rabies cases evolution from 1942 to 2015 is characterized by ascending phase then decreasing one following structured rabies control plan implementation in 1980s...

Troponins are sensitive markers of myocardial injury and predictive of cardiovascular events, but conventional assays fail to detect slightly elevated troponins in a considerable proportion of the general population. Using a novel ultrasensitive assay, we explored the relationship of troponin levels with the incidence of coronary heart disease (CHD) in a case-cohort sample (mean age 52.5 ± 0.2 years, 51.5% women) comprising 803 CHD cases and 1942 non-cases. Ultrasensitive troponin I was detectable in 99...

Current history would have you believe that the evolution and development of the electronic apex locator for use during root canal procedures emanated from the work of Suzuki in 1942, which was developed as a product by Sunada in 1962. Yes, this is partly correct, however the concept of using electrical means to locate the ends of root canals was brought to the dental profession as early as 1918 by Dr. Levitt Ellsworth Custer, which was not addressed until Suzuki revisited Custer's concepts. This contribution was only one of the many that Custer proffered as he championed the use of electricity in dentistry...

REVIEW
Deborah Charlesworth, Nicholas H Barton, Brian Charlesworth
The role of natural selection in the evolution of adaptive phenotypes has undergone constant probing by evolutionary biologists, employing both theoretical and empirical approaches. As Darwin noted, natural selection can act together with other processes, including random changes in the frequencies of phenotypic differences that are not under strong selection, and changes in the environment, which may reflect evolutionary changes in the organisms themselves. As understanding of genetics developed after 1900, the new genetic discoveries were incorporated into evolutionary biology...

Peste-des-petits ruminants (PPR) is one of the most important infectious diseases of domesticated small ruminants. From the initial identification in 1942 in West Africa, PPR virus (PPRV) has spread throughout much of the developing world. PPRV is now considered endemic throughout Africa, with the notable exception of South Africa, the Middle-East and Israel, as well as South-, East-, and Central Asia. Despite this widespread dispersal, the evolution and transmission of PPRV in endemic populations is not well understood...

REVIEW
Jan M Keppel Hesselink, David J Kopsky
Phenytoin is an 80-year young molecule and new indications are still emerging. The neuroprotective potential of phenytoin has been evaluated for decades. Recently, a positive phase II trial supported its further development in the treatment of optic neuritis in multiple sclerosis. In 1942, however, peripheral neuritis was first reported to be an adverse event of phenytoin, and since then a small but steady stream of publications discussed peripheral polyneuropathy as being a possible adverse event of phenytoin...
