Leukemia cell karyotypes were determined at diagnosis for 136 of 159 consecutive patients with acute lymphoblastic leukemia (ALL) who were followed for up to 35 mo. Ninety patients (67%) had abnormal karyotypes. Five chromosome categories were designated, based on the distribution of modal numbers: hyperdiploid greater than 50 (n = 41), hyperdiploid 47-50 (n = 18), pseudodiploid (n = 28), norma...

The subject of therapist's crying in therapy (TCIT) has been virtually ignored in the literature, with only 1 qualitative dissertation and 3 case studies devoted to the topic. This mixed-method survey study explored therapists' experiences with and attitude toward TCIT. Six hundred eighty-four U.S. psychologists and trainees filled out the survey online, revealing that 72% of therapists report ...

Climate change is recognized as an important threat to global biodiversity because it increases the risk of extinction of many species on the planet. Mexico is a megadiverse country and native tree species such as red cedar (Cedrela odorata) can be used to maintain forests while helping mitigate climate change, because it is considered a fast growing pioneer species with great economic potentia...

A trial to control G. m. morsitans with the use of 980 odour-baited, insecticide-impregnated targets was conducted in a 300 km2 area in the Eastern Province of Zambia between 1989 and 1991. The area is highly cultivated and cattle density is high (about 8 cattle/km2). Targets were deployed along roads and tracks. Deployment was restricted to suitable tsetse habitat. The effect of the targets on...

The great medieval settlement of Angkor in Cambodia [9th-16th centuries Common Era (CE)] has for many years been understood as a "hydraulic city," an urban complex defined, sustained, and ultimately overwhelmed by a complex water management network. Since the 1980s that view has been disputed, but the debate has remained unresolved because of insufficient data on the landscape beyond the great ...

Situated at the furthest northeastern edge of Canada, the island of Newfoundland (approximately 110,000 km2) and Labrador (approximately 295,000 km2) today constitute a province characterized by abundant natural resources but low population density. Both landmasses were covered by the Laurentide ice sheet during the Last Glacial Maximum (18,000 years before present [YBP]); after the glacier ret...

The exodus of people from rural areas to cities brings many detrimental environmental, social and cultural consequences. Monitoring spatiotemporal change by referencing the historical timeline or incidence has become an important way to analyze urbanization. This study has attempted to attain the cross-sectional analysis of Kathmandu valley that has been plagued by rampant urbanization over the...

The dynamic relationship between vegetation and climate is now widely acknowledged. Climate influences the distribution of vegetation; and through a number of feedback mechanisms vegetation affects climate. This implies that land-use changes such as deforestation will have climatic consequences. However, the spatial scales at which such feedbacks occur remain largely unknown. Here, we use a lar...
