A historical perspective of the growth and development of Pharmaceutical Biology.

In May 2011, Parliament in Uganda adjourned without debating a bill that included the death penalty for some homosexual acts.

The emergence of Hendra and Nipah viruses in the 1990s has been followed by the further emergence of these viruses in the tropical Old World. The history and current knowledge of the disease, the viruses and their epidemiology is reviewed in this article. A historical aside summarizes the role that ...

Although safety-specific transformational leadership is known to encourage employee safety voice behaviors, less is known about what makes this style of leadership effective. We tested a model that links safety-specific transformational leadership to safety voice through various dimensions of trust. Data from 150 supervisor-employee dyads from the United Kingdom oil ...

T his year marks the 150th anniversary of the birth, on 20 June 1861, of Frederick Gowland Hopkins, a father figure of modern biochemistry, which started around the beginning of the 20th century.

This lecture is not a historical lecture, but rather a journey through the "story" of neurology in Italy from its "prehistoric" beginning in the 19th century. The birth of a neurological school is that magical moment in which a founder attracts disciples: the more capable this founder is of transmitting ...

The First World War is traditionally considered in history as a temporary halt for cultural and sporting activities. If the Olympic Games and the Tour de France were actually cancelled, football and rugby were in fact stimulated by the circumstances of war. Indeed, the gathering of allied nations behind the ...

Dihydrogen trioxide (HOOOH) is formed nearly quantitatively in the low-temperature (-70 degrees C) methyltrioxorhenium(VII) (MTO)-catalyzed transformation of silyl hydrotrioxides (R3SiOOOH), and some acetal hydrotrioxides, in various solvents, as confirmed by 1H, and 17O NMR spectroscopy. The calculated energetics (B3LYP) for the catalytic cycle, using H3SiOOOH as a model system, is ...

The photochemistry of two isomeric aryl diazo ketones was investigated by fs time-resolved UV-vis and IR spectroscopies. Both diazo ketone excited states decompose in less than 300 fs by multiple pathways. One pathway involves concerted Wolff rearrangement and nitrogen extrusion, most likely in the syn rotomer. In the anti rotomer ...

This article deals with the history of Indian Alchemy and surveys its gradual and fertile growth in ancient India.

The dictum that patients who have plastic ventilation tubes (grommets) inserted in their tympanic membranes should not go swimming is questioned. A theoretical assessment is made of the pressure necessary to push water through a grommet. This value is compared with practical observations. These values are discussed with reference to ...

Roots and stems of Ottonia anisum contain besides 1-butyl-3,4-methylenedioxybenzene and piperovatine, the novel (2E,4E)-N-isobutyl-9-piperonyl-nona-2,4-dienoic amide.

Precise localization, detection, and recognition of minor changes in testicular lesions are important because teratocarcinoma is notorious for manifesting as secondaries at the time the primary site is obvious to the clinician. In the past, questionable enlargement of the testis due to significant pathology required numerous radiographic invasive special procedures ...

Animal-infective forms of Trypanosoma brucei (Strain 427) were successfully propagated in HEPES-buffered RPMI 1640 medium in the presence of bovine fibroblast-like cells for over 310 days. The organisms grown in this system were morphologically identical to the long slender bloodstream forms, retained their infectivity for mammalian hosts, and displayed variant-antigen ...

Using the electroretinogram as the criterion of retinal activity the flicker fusion frequency, course of dark adaptation, and spectral sensitivity of the pure cone retina of the diurnal gecko, Phelsuma inunguis, were investigated. Both the curve relating flicker fusion frequency to stimulus intensity and that relating the amplitude of the ...

Evidence relating to the structure and properties of swine pepsinogen and pepsin has been reviewed and used to suggest a tentative two dimensional picture of the skeleton of these two proteins. When pepsinogen, a folded single peptide chain, is converted to pepsin, there is a profound change in the physical ...

1. The enzyme which splits threonine to acetaldehyde and glycine has been partially purified from rat liver (five- to sixfold purification) and the name threonine aldolase proposed for it. 2. The general properties of threonine aldolase have been studied. The enzyme is unstable to a pH below 5. The pH ...

(a) Photosynthesis with protoplasm isolated from Chara or Nitella as measured by C(14) fixation has been obtained at a rate 12 to 15 per cent of that of the whole cells. (b) Photosynthesis by cut cells of Chara or Nitella with the vacuolar sap removed was at a rate comparable ...
