Snow survey by aerial photographs

GeoJournal, 1972
On the occasion of the heavy snow fall in January, 1963 in Hokuriku district the Geographical Survey Institute started its snow surveys by aerial photographs on a scale of 1 : 20, 000. Snow depth was measured at snow fissures on the slopes or exposed snow sections near the water on the photographs, using Stereotope, the third order instrument.

Lactoferrin treatment activates acetylcholinesterase, decreasing acetylcholine levels in non‐small cell lung cancer (NSCLC) cell culture supernatants, inhibiting cell survival

FEBS Open Bio, EarlyView.
Representation of the suggested mode of action of lactoferrin (Lf) in nonsmall cell lung cancer (NSCLC) A549 cells. Lf induces activation of caspase‐3 by activating p53 and AChE leading to decreased ACh concentrations. In turn, ACh signaling leads to activation of VEGF and AKT and blocking of caspase‐3.

Long‐term culture of skin biopsies: maintenance of fibroblast production and competency of reprogramming

FEBS Open Bio, EarlyView.
Skin biopsies taken from a patient with an ultra‐rare disorder as well as controls were cultured for up to 473 days. The chunks of skin were serially transferred to a new culture plate when confluent with fibroblasts. Different generations of fibroblasts were analyzed for cell and molecular properties, proliferation, and competence for reprogramming to

Abundance and density of lesser prairie‐chickens and leks in Texas

Wildlife Society Bulletin, 2013
Lesser prairie‐chickens (LEPCs; Tympanuchus pallidicinctus) have experienced population declines due to both direct and indirect habitat loss, including conversion of native rangeland to cropland and disturbance from energy development.
