Incompatibility systems in which individuals bearing identical alleles reject each other favor the maintenance of a diversity of alleles. Mushroom mating type loci (MAT) encode for dozens or hundreds of incompatibility alleles whose loss from the population is greatly restricted through negative frequency selection, leading to a system of alleles with highly divergent sequences. Here, we use DN...

Purpose. To improve the elements of technology for growing tomato hybrids by method low-volume hydroponics in glass greenhouses conditions IV light zone Ukraine. Conduct an economic and biological assessment establish response new F1 to environmental factors; study dynamics fruiting determine most early-ripening productive ones; influence plant productivity on yield formation when grown greenho...

Våren 1999 handlade Folkkultursarkivets årliga frågelista om mathushållning med tyngdpunkt på dagens förhållanden. Frågelistan "Vad har vi för mat i dag?" väckte stort intresse och sammanlagt kom det in 161 svar som omfattar drygt 1000 sidor text. Åldersspridningen var stor. De äldsta svarade är födda 1910-talet, de yngsta 1990-talet. Därmed återspeglas så gott hela 1900-talet frågesvaren efter...

Differences in cell morphology, concanavalin A-induced receptor redistributions, and the cooperativity of the inhibition of 5'-nucleotidase (AMPase) by concanavalin A (Con A) have been investigated in ascites sublines of the 13762 rat mammary adenocarcinoma cells treated with microfilament- and microtubule-perturbing drugs. By scanning electron microscopy MAT-C1 cells exhibit a highly irregular...

PURPOSE Meniscal allograft transplantation (MAT) has become an accepted treatment option for patients undergoing meniscectomy with recalcitrant pain in the corresponding compartment. Whether MAT can oppose cartilage degeneration is unclear. Our purpose was to perform a systematic review of available literature to answer the following: (1) Does MAT prevent advancing chondrosis? (2) Who is the id...

Marrow adipose tissue (MAT) is an endocrine organ with the potential to influence skeletal remodeling and hematopoiesis. Pathologic MAT expansion has been studied in the context of severe metabolic challenge, including caloric restriction, high fat diet feeding, and leptin deficiency. However, the rapid change in peripheral fat and glucose metabolism associated with these models impedes our abi...
