The Factorial Analysis of Crop Productivity

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1954
Summary The main purpose of this paper is to illustrate how the methods of factor analysis developed by psychologists to analyse what might be called mental productivity may be usefully applied to agricultural data, in order to deal with such problems as crop productivity.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Growth and yield enhancement of lowland rice cultivars by arbuscular mycorrhizal fungi in phosphorus-deficient conditions

Discover Environment
Phosphorus deficiency limits rice production in lowland savannah regions. This study investigated the effects of phosphorus deficiency and arbuscular mycorrhizal fungal (AMF) inoculation on lowland rice cultivars under varying water regimes.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Effects of Cash Crop Production on Food Crop Productivity in Zimbabwe: Synergies or Trade-offs? [PDF]

This paper studies the dynamics between cash cropping and food crop productivity in Gokwe North District in Zimbabwe, a major cotton producing area. The main research issues were: (1) to identify the determinants of commercialized crop production at the ...

Influence of different organic mineral fertilization on the yield structure and on changes of soil properties

Plant, Soil and Environment, 2002
The monitoring was carried on in the years 1996-2000 in the international IOSDV (Internationale Ökologische Stickstoff Dauer Versuche) field trial running since 1983 in Lukavec, Pelhřimov district.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Partial FAK suppression promotes tumor growth, an effect reversed by macrophage p110δ PI3K inactivation

Molecular Oncology, EarlyView.
Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

Mitigating the trade-off between grain yield and vegetative biomass with orthosilicic acid towards enhancing lodging resistance in upland rice

Discover Plants
Achieving a balance between high yield and strong lodging resistance (LR) remains a major challenge in rice improvement, as shifts in biomass accumulation and allocation can enhance yield but weaken plant architecture.
