Calreticulin (Crt) is a molecular chaperone ubiquitously present in the endoplasmic reticulum. In non-human primates, age-related occurrence of anti-Crt antibody has not been reported. We developed an ELISA assay for an anti-Crt antibody and determined the age-related increase in the levels of anti-Crt antibody in three groups of cynomolgus monkeys: juvenile (1.

Theonellamide F induced large vacuoles in 6 types of mammalian cells. The vacuoles induced by theonellamide F in 3Y1 cells accumulated acridine orange, a fluorescent probe indicating the presence of an acidic organelle.

Though somnambulism (sleepwalking) is a well-recognized sleep disorder in humans, a biomedical literature search in Medline and Primate Literature bibliographic databases showed no publications on sleepwalking in non-human primates. From this finding, two inferences can be made. First is that somnambulism may be present in non-human primates; but due to limitations in expertise and methodological resources as well as narrow focus of research interest, until now researchers have not detected it in wild and/or captive conditions.

Since the oxidative stress state (OSS) of an individual depends on hereditary, dietary, and environmental factors, there is a large heterogeneity in the population that may be related to disease incidence and longevity. Hence there is a need to assess how well an individual is coping against OS.

In this paper, I report that Alfred Nobel's creativity can be assigned to two mutually exclusive domains. In the scientific domain, he solved a well-defined problem of his time in the study of explosives, by patenting dynamite, creating blasting gelatin as an ideal explosive and developing a nearly smokeless blasting powder.

The life of 19th century Swedish chemist cum inventor Alfred Nobel can be conveniently divided into two equal phases: pre-nitroglycerine phase (1833-1863) and nitroglycerine phase (1864-1896). According to the records of Ragnar Sohlman, his assistant during his last year of life, Nobel's physical condition began to decline towards the end of the 1870s, and for the last 16 years he suffered from deep depression and anginal pains. Based on Nobel's descriptions of his condition, on his prolonged experimentation with explosives, his strenuous work habit and some recent knowledge about nitroglycerine poisoning, I hypothesize that nitroglycerine poisoning was an aggravating factor which contributed to Nobel's deteriorating health and premature death at the age of 63.

L- Carnosine (beta-alanyl L-histidine), occurring abundantly in skeletal muscles, has been suggested to possess antioxidant and anti-aging properties. Using three different experimental approaches (microscopic, flow cytometric and ELISA for one of the markers of DNA oxidative damage) this study on rat embryonic fibroblasts demonstrates that L-carnosine at 30 mM concentration sustains the retention of cell morphology even during a nutritional insult for five weeks. Also, L-carnosine significantly reduces the formation of 8-hydroxy deoxyguanosine (8-OH dG) in the cells after four weeks of continuous culture.

Three assumptions made for this comparison were (1) that Einstein and his designated controls had equal scientific stature; (2) that their publications were produced in a similar, if not identical, sociocultural milieu; and (3) the number of publications is directly proportional to scientific productivity. At the end of their illustrious careers, Einstein, Freud and Landsteiner accumulated 315, 320 and 345 scientific publications respectively.

In each period (Munich, Switzerland, Berlin and Princeton) of his life, one could identify the medically qualified individuals with whom Einstein was in close contact. These include Max Talmey, Heinrich Zangger, George Nicolai, Hans Mühsam, Janos Plesch and Gustav Bucky.

This is because, among the three existing terms: (a) 'the search for extraterrestrial intelligence' 'excludes biology and is inelegant'; (b) 'extraterrestrial' does not distinguish between the micro-organisms and highly-evolved intelligent life-forms; and (c) 'unidentified flying object' projects a sense of mysticism. On the presence of galactic organisms with distinct intelligence, scientists belong to three camps.

Seasonal changes in the in vivo levels of the prostaglandins (PGs) PGD2, PGE2, and PGF2(alpha) were measured in the brain of the male Asian chipmunk, Tamias asiaticus (n = 111), which underwent hibernation during the period between November and March. The mean level of PGD2 ranged from 36.0 to 85.

A 1900 publication authored by Karl Landsteiner, at the age of 32 years, contained a footnote which stated that, "the serum of healthy human beings not only agglutinates animal red cells, but also often those of human origin, from other individuals". He followed up this statement in his 1901 paper, and concluded that, "My observations reveal characteristic differences between blood serum and red blood cells of various apparently healthy persons" and that "the reported observations may assist in the explanation of various consequences of therapeutical blood transfusions". These significant observations resulted in the discovery of A, B, O and AB blood groups and later led to successful blood transfusions in humans.

The research contributions of 24 Nobelists in medicine (contemporaries of Einstein) who received the Nobel prize between 1912 and 1966 were analyzed. When assessed on three criteria, (a) influence in multiple disciplines, (b) revolutionary in opening new vistas of knowledge, and (c) significant impact to human life, Karl Landsteiner's discoveries of the human blood groups stand out prominently. Thus, Landsteiner seems an appropriate choice to use as a 'control' to analyze Einstein's productivity.

The site of action for the sleep-promoting effect of prostaglandin (PG) D2 was extensively examined in the brain of adult male rats (n = 231). PGD2 was administered at 100 pmol/0.2 microliter per min for 6 hr (2300-0500 hr) through chronically implanted microdialysis probes or infusion cannulae.

His health problems were primarily related to multiple complications of digestive system disorders; liver ailment, stomach ulcer, inflammation of gall bladder, jaundice and intestinal pains. Based on the published autobiographical records and biographies written by his secretary Helen Dukas and collaborators such as Philipp Frank and Banesh Hoffmann, this paper appraises the chronic illness of Einstein.
