Stress May Drive Plant Patterns

Plants grow in a wondrous assortment of patterns, from simple to complex, with near mathematical precision. Honeysuckles sprout leaf pairs at regular intervals along their stems, for instance, whereas some succulents form double spirals turning in opposite directions. The big question is how do they do this? New research reported in this issue of PLoS Biology suggests that mechanical stress is ...

Effects of different spinal morphine doses in rats.

BACKGROUND AND OBJECTIVES Spinal morphine promotes adequate pain relief, but is not free from side effects. This study aimed at investigating the effects of different spinal morphine doses. METHODS Five groups of seven rats were studied, 24 h after spinal catheter insertion via cisterna magna under anesthesia with muscular ketamine and xylazine. G1 received 10 microl saline solution; groups G...

Ecological Facilitation May Drive Major Evolutionary Transitions

Intranasal delivery of morphine may offer better effects.

Researchers from Memorial SloanKettering Cancer Center have created a formula that older, long-term smokers and ex-smokers can use to calculate their risk for developing lung cancer. Lung cancer risk is dependent on each individual’s smoking pattern and history. For example, when the formula is used to compute risk, a 52-year-old woman who smoked a pack of cigarettes per day for 25 years and qu...

Low Serum Zinc Level May be Related to Higher Doses of EPO in Hemodialysis Patients

Introduction. Anemia is a complication of chronic renal failure observed in patients on hemodialysis (HD) affecting morbidity and mortality of these patients. It is associated with erythropoietin (EPO) deficiency and can be treated by human recombinant erythropoietin (hrEPO). Iron deficiency has been reported as the first line cause for inadequate response to this treatment. Zinc deficiency in ...
