Case Report A white male aged 37 years was referred to one of us (L.M.) by a general practitioner on August 3, 1959, because of a painful lump on the right side of the nose of 10 days' duration. The condition had been treated as a dacryocystitis with antibiotics by mouth, oxytetracycine eye ointment, and infra-red rays for 4 days. In spite of the treatment the lump had grown larger. The right e...

In the wilds of Africa, when it’s time for a family of elephants gathered at a watering hole to leave, the matriarch of the group gives the “let’s-go rumble” — as it’s referred to in scientific literature — kicking off a coordinated and well-timed conversation, of sorts, between the leaders of the clan. First, the head honcho moves away from the group, turns her back and gives a long, slightly ...

Drought down-regulates above- and belowground carbon fluxes, however, the resilience of trees to drought will also depend on the speed and magnitude of recovery of these above- and belowground fluxes after re-wetting. Carbon isotope composition of above- and belowground carbon fluxes at natural abundance provides a methodological approach to study the coupling between photosynthesis and soil re...

The effects of exogenous abscisic acid (ABA) and its two agonists, Sulfacetamide (Sa) and Sulfasalazine (SS) on tolerance of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under drought stress were studied. Eight-week plants were treated with ABA (25 and 50 mg/L), Sulfacetamide (Sa) (25, 50 and 100 mg/L) and Sulfasalazine (SS) (25, 50 and 100 mg/L). Solutions were sprayed daily and samp...

Short-term waterlogging stress-induced changes in phosphatase (P-ase) activities in relationship with phosphorus were studied in sorghum (Sorghum bicolor). Waterlogging was imposed by watering 3-day-old grown seedlings with water. The shoots and roots were harvested and P-ase activities were estimated. Significant waterlogging stress-induced increase in shoot and root P-ase activities coupled w...

Climate change is expected to alter precipitation patterns. Droughts may become longer and more frequent, and the timing and intensity of precipitation may change. We tested how shifting precipitation patterns, both seasonally and by frequency of events, affects soil nitrogen availability, plant biomass and diversity in a shrub-steppe temperate grassland along a natural productivity gradient in...

In this paper, the authors examine the impacts of large price changes (or shocks) on the abnormal returns (ARs) of a set of 39 national stock indices. Their initial results support returns continuations for both positive and negative shocks in line with prior results. After controlling for market size, their findings provide support for over-reaction, return continuations and market efficiency,...
