Ailanthus altissima and Robina pseudoacacia are two successful invasive species of floodplains in central Spain. We aim to explain their success as invaders in this habitat by exploring their phenological pattern, vegetative and sexual reproductive growth, and allometric relations, comparing them with those of the dominant native tree Populus alba. During a full annual cycle we follow the timin...

Studies on molecular mechanisms of self-renewal in normal stem cells are required for understanding the cancer stem cell. Self-renewal in many kinds of normal stem cells might be accelerated in the growth of a young organism and in the repair of damaged tissue. This study examined whether the esophagus in growing neonates provides an experimental system for studies on epithelial stem cell renew...

The availability of nitrogen (N) and zinc (Zn) at the specific plant growth stage is crucial for attaining higher nutrient use efficiency (NUE) uptake. An experiment was conducted, having 4-N scheduling [No N; ½[basal]+ ½[3rd visible leaf (VL)]; ¼[basal]+ ½[3rdVL]+ ¼[panicle extended in flag sheath (PEFLS)]; ½[basal] + ¼[3rdVL]+ (PV)], 4-Zn Zn; 2.5 kg/ha [basal]+ 0.25% spray(*) [panicle initiat...

Interactions between tree species determine the dynamics of forest communities. Spatial and temporal changes in resource availability, variation composition spatial distribution trees may alter competitive interactions and, therefore, affect growth productivity. In this study, we analyzed intra inter-specific European beech (Fagus sylvatica L.) silver fir (Abies alba Mill.) southern Italy (Moli...

Background and Objective: Clinical behavior of basal cell carcinoma (BCC) is known to be different according to histological growth pattern and basosquamous cell carcinomas (BSC) are known with their aggressive behavior and metastatic capacity. In this study, we evaluated bcl-2 and cyclin D1 expressions in BCC and BSC cases comparatively, to explore their predictive value on the aggres...

The objective of this study is to evaluate the capability of satellite imagery for the estimation of basal area in Northern Zagros Forests. The data of the high resolution geometric (HRG) sensor of SPOT-5 satellite dated in July 2005 were used. Investigation of the quality of Satellite images shows that these images have no radiometric distortion. Overlaying of geocoded images with the digital ...

Conclusions drawn from the pancreatic (or islet) clamp technique (suppression of endogenous insulin, glucagon, and growth hormone secretion with somatostatin and replacement of basal hormone levels by intravenous infusion) are critically dependent on the biological appropriateness of the selected doses of the replaced hormones. To assess the appropriateness of representative doses we infused sa...

Proactive silviculture treatments (e.g., thinning) may increase C sequestration contributing to climate change mitigation, although, there are still questions about this effect in Mediterranean pine forests. The aim of research was quantify the storage biomass and soil organic carbon Pinus forests along a climatic gradient from North South Iberian Peninsula. Nine experimental spp trials were se...
