Cassia fistula, a flowering plant in the family of Caesalpinaceae (Fabaceae), is used in traditional medicine for several indications. Nevertheless, too little is known about its effects on skin conditions and skin aging. Therefore, in this pioneering study, the extracts of oil-in-water macro-emulsions containing 5% C. fistula (L.) crude pods (i.e., phyto-active formulation) were optimally deve...

Like other color centers (VK, H ) the OF-center in alkali halides has a strong molecular character. It is shown that methods similar to those used in the theory of transition metal salts lead to an understanding of the electronic ground state and g-factor of the Of-center. It is necessary to invoke a weak covalent bonding with the neighbouring ions. This bonding manifests itself in the crystal ...

Ore bodies from which gold is mined are often composed of minerals containing sulfur, sellenium and tellurium. Mercury is also associated with these three elements and is simultaneously dissolved during gold extraction. When cyanide salts are used to extract gold, mercury cyanide complexes that form enhance mercury mobility and increase mercury concentrations in groundwater. In one instance thi...

There is increasing evidence for intercellular trafficking of macromolecules through plasmodesmata (PD) during plant development. Here we study the ability of PD to traffic proteins during embryogenesis and early seedling development in Arabidopsis. Transgenic lines that induce GFP expression only in meristems, MSG (meristem-specific GFP), were used to monitor GFP movement. Cell-to-cell movemen...

L'objectif de cette étude est de déterminer la fréquence, de décrire les circonstances de découverte, les signes cliniques et paracliniques, la composition chimique des calculs prélevés et les difficultés rencontrées dans le traitement des lithiases urinaires. Notre étude a été rétrospective sur une période de six ans (janvier 2005 à décembre 2010) et a eu pour cadre le CHUP-CDG et a concerné 6...

Intense underwater sounds caused by military sonar, seismic surveys, and pile driving can harm acoustically sensitive marine mammals. Many jurisdictions require such activities to undergo marine mammal impact assessments to guide mitigation. However, the ability to assess impacts in a rigorous, quantitative way is hindered by large knowledge gaps concerning hearing ability, sensitivity, and beh...

The prime objective of current investigation was to develop a topical skin care cream (w/o) loaded with Ananas comosus extract versus placebo control, and evaluated non-invasively for changes in skin barrier function i.e., epidermal hydration levels and transepidermal water loss (TEWL), on healthy human volunteers. Active cream carrying 2% extract of Ananas comosus in the internal phase of w/o ...

In the work described in this paper, a method has been developed for direct microscopic observation of the smaller blood vessels of the mammalian lung in the unopened thorax. The behavior of these vessels and the flow of blood through them have been studied under a variety of conditions. We were particularly interested in their normal behavior, in the question of intermittence of the flow of bl...
