Beating the cold: The role of OsTTG1 in developing cold-resistant rice

Plant Physiology
In the face of unpredictable climate patterns, crop growth and yield are becoming increasingly vulnerable, with rice—a staple food crop—being no exception. While much attention has been paid to heat stress and its impact on crops, the effects of cold stress on rice remain underexplored.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Improvements of the Variable Thermal Resistance [PDF]

, 2007
A flat mounting unit with electronically variable thermal resistance [1] has been presented in the last year [2]. The design was based on a Peltier cell and the appropriate control electronics and software. The device is devoted especially to the thermal

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Redefining awn development in rice through the breeding history of Japanese awn reduction

Frontiers in Plant Science
The study challenges the conventional understanding of awn loss as a domestication syndrome, showing instead that many awned varieties continued to be widely grown in Japan until the early twentieth century and that selection for awn reduction was active

Brassinosteroids participate in the control of basal and acquired freezing tolerance of plants [PDF]

, 2016
Brassinosteroids (BRs) are growth-promoting plant hormones that play a role in abiotic stress responses, but molecular modes that enable this activity remain largely unknown. Here we show that BRs participate in the regulation of freezing tolerance.

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Application of molecular genetic methods in rice breeding for cold resistance

Зерновое хозяйство России
Low positive temperatures have a negative impact on all processes occurring at all stages of rice development. This is especially true during the period of seed germination and sprouting, resulting in reduced seed energy and growth strength.

Promoting Antibiotic Stewardship [PDF]

, 2017
Antibiotics are not always prescribed optimally in the outpatient setting for common respiratory illnesses. Providers also spend time reiterating the same facts to patients about antibiotics and why their use is not warranted for their common cold ...
