Kidney development requires reciprocal interactions between the ureteric bud and the metanephrogenic mesenchyme. Whereas survival of mesenchyme and development of nephrons from mesenchymal cells depends on signals from the invading ureteric bud, growth of the ureteric bud depends on signals from the mesenchyme. This codependency makes it difficult to identify molecules expressed by the ureteric...

Bud outgrowth is a key process in the elaboration of yield and visual quality in rose crops. Although light intensity is well known to affect bud outgrowth, little is known on the mechanisms involved in this regulation. The objective of this work was to test if the control of bud outgrowth pattern along the stem by photosynthetic photon flux density (PPFD) is mediated by sugars, cytokinins and/...

Plant architecture is shaped by endogenous growth processes interacting with the local environment. The current study investigated crown development in young black alder trees, assessing the effects of local light conditions and branch height on individual bud mass and contents. In addition, we examined the characteristics of parent shoots [the cross-sectional area (CSA) of stem and total leaf ...

In budding yeast, the mitotic spindle moves into the neck between the mother and bud via dynein-dependent sliding of cytoplasmic microtubules along the cortex of the bud. How dynein and microtubules interact with the cortex is unknown. We found that cells lacking Num1p failed to exhibit dynein-dependent microtubule sliding in the bud, resulting in defective mitotic spindle movement and nuclear ...

BACKGROUND COPD patients have a higher risk of pneumonia when treated with fluticasone propionate (FP) than with placebo, and a lower risk with budesonide (BUD). We hypothesized that BUD and FP differentially affect the mucosal barrier in response to viral infection and/or cigarette smoke. METHODS We assessed protective effects of equivalent concentrations of BUD and FP on cytokine production...

Functional implications of the recently described fatty acid conjugation of budesonide (BUD) (Tunek, A., K. Sjödin, and G. Hallström, Drug Metabol. Dispos. 1997;25:1311-1317; Miller-Larson, A., E. Hjertberg, H. Mattsson, M. Dahlbäck, A. Tunek, and R. Brattsand, Am. J. Respir. Crit. Care Med. 1997;155:A353 [Abstr.]) were studied in a rat cell line, Rat1, transfected with the activation protein-1...

Mitochondria accumulate at neuronal and immunological synapses and yeast bud tips and associate with the ER during phospholipid biosynthesis, calcium homeostasis, and mitochondrial fission. Here we show that mitochondria are associated with cortical ER (cER) sheets underlying the plasma membrane in the bud tip and confirm that a deletion in YPT11, which inhibits cER accumulation in the bud tip,...

BACKGROUND S. cerevisiae cells must grow to a critical size in G1 in order to pass start and enter the cell cycle. A recent study proposed that in addition to the mother size control in G1, the bud must grow to a critical bud size in G2 in order to enter mitosis. Insufficient bud size would cause G2 arrest enforced by the mitotic inhibitor Swe1p, explaining previous findings that some perturbat...

aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. this species has been endangered at northern forests of iran; therefore micropropagation of adult trees by bud culture may help to reforestation. the best sterilizing treatment was the buds washing with hgcl2% 0.1 solution for 7 ...

Hydrofluoroalkane-134a (HFA) beclomethasone dipropionate (BDP) extrafine aerosol is a pressurized metered dose inhaler (pMD1) available for the treatment of asthma. Unlike most pMDIs, HFA-BDP is a solution, rather than a suspension, of BDP in HFA propellant. This reforrnulation, combined with improvements in inhaler technology, results in the production of aerosol particles of smaller mean mass...
