A 44-year-old man on active duty in the Marines presented with a dry, red patch of skin on his back that had been present for two days. The rash was pruritic and painful to touch. There was no discharge from the lesion. The patient did not have fever or new environmental co...

The term "alkaliphile" is used for microorganisms that grow optimally or very well at pH values above 9 but cannot grow or grow only slowly at the near-neutral pH value of 6.5. Alkaliphiles include prokaryotes, eukaryotes, and archaea. Many different taxa are represented among the alkaliphiles, and some of these have been proposed as new taxa. Alkaliphiles can be isolated from normal environmen...

Introduction: Poisonings are an important problem in children. Identifying risk factors related with unintentional poisonings can help reduce their incidence and severity. The objective of this study was to define the characteristics of unintentional poisonings in children, with particular attention on drugs and household products. Materials and Methods: Observational retrospective study perfor...

Pricing Prototypical Products When we think of colas, Coca-Cola first comes to mind. Products such as Cola-Cola, Tide laundry detergent and Chapstick lip balm are the prototypical products in their respective categories. Over three decades, research in consumer psychology has accumulated evidence on how prototypicality structures memory, shapes the composition of consideration set and influence...

Eutrophication, regarded as the most immediate environmental consequence of extensive phosphorus usage in contemporary societies, has received wide attention. If the current level of human-induced global environmental impacts continues, there is a chance of occurrence of nearly 2.4–2.7-fold increase in nitrogen and phosphorus driven eutrophication of terrestrial, freshwater and marine ecosystem...

Proteases are a group of enzymes, found in all living organisms and are essential for the cell growth and differentiation. The proteases have wide applications in pharmaceutical, leather, laundry, food and waste processing industries. Their catalytic function is to hydrolyze peptide bonds of proteins and break them down into polypeptides or free amino acids. The present study was aimed at isola...

The common bed bug, Cimex lectularius (L.) (Hemiptera: Cimicidae) is known to become associated, from time to time, with clothing or linen. In such locations, it may escape insecticide treatment, and may be carried to new locations. We test the suggestion that laundering is sufficient to kill all life stages and thus help prevent reinfestation and dispersion. We establish minimum temperatures f...
