Fast growth conditions uncouple the final stages of chromosome segregation and cell division in Escherichia coli. [PDF]

PLoS Genetics, 2017
Homologous recombination between the circular chromosomes of bacteria can generate chromosome dimers. They are resolved by a recombination event at a specific site in the replication terminus of chromosomes, dif, by dedicated tyrosine recombinases.

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie International Edition, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Angiotensin I-Converting Enzyme Inhibitory Substances in Black Matpe.

Nippon Eiyo Shokuryo Gakkaishi, 1998
ブラックマッペ, その発芽体, およびブラックマッペ抽出粉末試料のペプシン加水分解物中のACE阻害活性を調べ, ブラックマッペに含まれる阻害因子について精製を試みた。またペプシン加水分解物をSHRに投与し, 生体内での効果をも検討した。1) ブラックマッペおよびその発芽体の抽出液にACE阻害活性が認められた。2) この物質を精製したところ, ゲル濾過より分子量は400～800と推定された。またおもな阻害因子は逆相カラムには吸着されず, 水系の溶媒で溶出し親水性の物質と推察された。3) この阻害因子はペプシンで分解されなかった。またブラックマッペ抽出物中のタンパク質を, ペプシン処理した加水分解物には, 活性が認められなかった。4) ブラックマッペ抽出粉末試料のペプシン加水分解物を ...

TGF‐β1 Directly Sensitizes Capsaicin‐Sensitive Lung Vagal Neurons to Promote Airway Hypersensitivity

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Transforming growth factor‐β1 (TGF‐β1) is a pleiotropic cytokine implicated in the pathogenesis of inflammatory airway diseases such as asthma. Airway hypersensitivity (AHS), arising from sensitization of capsaicin‐sensitive lung vagal (CSLV) afferents, is a hallmark of these airway diseases.

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...

Localization of MatP and SlmA on the E. coli chromosome.

, 2013
E. coli cells expressing fluorescent derivatives of matP (matP-Cherry) (top panel) and SlmA (GFP-SlmA) (bottom panel). An overlay of phase contrast and fluorescence images is shown for matP, whereas separate fluorescence and DIC images are shown for SlmA.

Recovery of Vibrio cholerae polarized cellular organization after exit from a non-proliferating spheroplast state.

PLoS ONE, 2023
Vibrio cholerae, the causative agent of cholera epidemics, is a rod-shaped bacterium with a highly polarized cellular organization. It can survive harmful growth conditions by entering a non-proliferating spheroplast state, which involves loss of the ...

The Antipsychotic Aripiprazole Induces Cytotoxicity in Bladder Cancer Cells While Preserving Urothelial and Bladder Function

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
Current bladder cancer therapies can cause toxicity and bladder dysfunction. Brief intravesical‐like aripiprazole exposure reduced bladder cancer cell viability and was associated with redox stress and caspase‐3 activation, while ex vivo findings suggested preserved bladder structure and function, warranting further investigation as a potential ...
