Toward the remote monitoring of armed conflicts.

The war in Ukraine has pushed the role of satellite imagery in armed conflicts into the spotlight. For a long time, satellite images were primarily used for military and intelligence purposes, but today they permeate every aspect of armed conflicts. Their importance in influencing the course of armed conflicts will further grow as progress in deep learning makes automated analysis progressively possible.

Isolation and partial characterization of insulin of the honeybee (Apis mellifica).

In the honeybee (Apis mellifica), insulin-like material was partially purified with acid ethanol extractions by a classic method for recovering insulin and following gel filtration on a Sephadex G-50 column. The preparations were characterized by their ability to cross-react with porcine insulin antibodies. Insulin-like biological activity was demonstrated using the insulin bioassay.

Insulin as a growth regulator of arterial smooth muscle cells: effect of insulin of I.G.F.I.

The proliferation of smooth muscle cells in the vessel wall plays an important role in the development of an atherosclerosis. The insulin-like growth factor I (I.G.

Interaction of receptors for insulin-like growth factor I, platelet-derived growth factor, and fibroblast growth factor in rat aortic cells.

Serum contains various growth factors which regulate the proliferation of cells. We investigated the growth of cultured arterial smooth muscle cells under the influence of insulin-like growth factor I (IGF I), fibroblast growth factor (FGF), and platelet-derived growth factor (PDGF), and examined the effect of these growth factors on the binding of [125I] IGF I and on the binding of [125I]PDGF to these cells. IGF I, FGF, and PDGF stimulated [6-3H]thymidine incorporation into DNA of confluent cultures of cells which were incubated in modified Dulbecco's modified Eagle medium.

Radioimmunoassay for the measurement of insulin-like growth factor I in patients with pituitary disease in comparison with commercially available somatomedin-C radioimmunoassays.

A highly sensitive and specific radioimmunoassay for the measurement of insulin-like growth factor I (IGF I) has been developed. The IGF I concentrations were measured in sera of normal subjects, patients with acromegaly, hypophysectomized patients and patients with hyperprolactinaemia. The results were compared with the results obtained after measurement of IGF I in the sera of the same patients with two commercially available radioimmunoassays for somatomedin-C.
