Enhanced soil quality with reduced tillage and solid manures in organic farming – a synthesis of 15 years

open access: yesScientific Reports, 2020
Demands upon the sustainability of farming are increasing in step with climate change and diversity loss. Organic farming offers a viable approach. To further improve organic management, three strategies with potential to enhance soil quality are being ...

Short-term impacts of different tillage practices and plant residue retention on soil physical properties and greenhouse gas emissions

open access: yes, 2021
Reducing tillage intensity and plant residue retention have the potential to mitigate climate change by reducing soil greenhouse gas emissions. Few comparative studies have explored the effects of different tillage practices and plant residue retention ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Genome-wide identification of CRF gene family members in four rice subspecies and expression analysis of OsCRF members in response to cold stress at seedling stage

open access: yesScientific Reports
Cytokinin Response Factors (CRFs) play a crucial role in plant growth and development, hormone signaling, and responses to biotic and abiotic stresses. However, there have been no reports on CRF genes in rice until now.

Exogenous melatonin confers drought stress by promoting plant growth, photosynthetic capacity and antioxidant defense system of maize seedlings [PDF]

open access: yesPeerJ, 2019
Melatonin is an important biologically active hormone that plays a vital role in plant growth and development. In particular, it has been investigated for its roles in abiotic stress management.

Straw Return and Nitrogen Fertilization to Maize Regulate Soil Properties, Microbial Community, and Enzyme Activities Under a Dual Cropping System

open access: yesFrontiers in Microbiology, 2022
Soil sustainability is based on soil microbial communities’ abundance and composition. Straw returning (SR) and nitrogen (N) fertilization influence soil fertility, enzyme activities, and the soil microbial community and structure.

Residue retention promotes soil carbon accumulation in minimum tillage systems: Implications for conservation agriculture.

open access: yesScience of the Total Environment, 2020
Crop residue retention and minimum tillage (including no-tillage, NT, and reduced tillage, RT) are common conservation tillage practices that have been extensively applied for improving soil health and reducing the negative environmental impact caused by

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Precision Tillage: Online variation of tillage depth

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Agriculture, 1970
Precision Farming equipment is more and more common on modern, large scale farm enterprises. With basic equipment being available, an important condition for the use of site-specific approaches is given. Site-specific approaches may help to increase the efficiency of a farm enterprise, as well as may help to achieve certain, predefined goals.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
