Investigations into the molecular mechanism of the bacterial stringent response

open access: yes, 2017
When bacterial cells encounter amino acid starvation or certain other adverse growth conditions, they initiate a ‘global’ regulatory process known as the stringent response.

Facile fabrication of polyurethane-based graphene foam/lead zirconate titanate/polydimethylsiloxane composites with good damping performance

open access: yes, 2018
Using three-dimensional graphene foam as the conductive phase, the temperature range where tan δ > 0.3 for a piezo-damping PGPP composite is broadened to −70 to 100 °C.

Measurement of the neutral kaon regeneration amplitude in carbon at momenta below 1 GeV/c

open access: yes, 1997
The neutral kaon regeneration amplitude in carbon at momenta between 250 and 750~MeV/$c$ was determined by measuring the interference of inherent and coherently regenerated \PKS\ amplitudes.

The importance of the fixation of colour, pattern and form in tropical Pseudocerotidae (Platyhelminthes, Polycladida)

open access: yes, 1995
At last a fixation method that ensures tropical pseudocerotid polyclads are fixed flat, preserved for histological preparation and which also retains their colour pattern has been developed.

The twists and turns of alarmone synthesis in Treponema denticola

open access: yes, 2021
Upon encountering certain environmental stresses, such as amino acid or carbon nutrient starvation, bacteria synthesize two hyper-phosphorylated guanine nucleotide ‘alarmone’ molecules: guanosine 5’-triphosphate, 3’-diphosphate (ppGpp) and guanosine 5’,3’

Herbal Medicine in Diabetes Mellitus: Effectiveness of Punica Granatum Peel Powder in Prediabetics , Diabetics and Complicated Diabetics.

open access: yes, 2015
Diabetes mellitus (DM) is a common worldwide chronic metabolic disorder. Heredity and obesity are well known risk factors for diabetes. DM is one of  the earliest described health problems, nevertheless it is still incurable disease.
