Regulation of pathway choice in DNA repair after double-strand breaks.

DNA damage signaling is a highly coordinated cellular process which is required for the removal of DNA lesions. Amongst the different types of DNA damage, double-strand breaks (DSBs) are the most harmful type of lesion that attenuates cellular proliferation. DSBs are repaired by two major pathways-homologous recombination (HR), and non-homologous end-joining (NHEJ) and in some cases by microhomology-mediated end-joining (MMEJ).

From an Invasive Weed to an Insecticidal Agent: Exploring the Potential of in Insect Management Strategies-A Review.

is weed with a wide range of chemical constituents, including primary and secondary metabolites such as alkaloids, flavonoids, tannins, saponins, and terpenoids. These compounds contribute to its medicinal and pesticidal potential. The essential oils and different solvent fractions derived from exhibit notable variations in their respective chemical compositions across various plant parts, spatial distributions, and interspecific comparisons.

Solid-state self carbo-passivation for refurbishing colloidal dispersity of catalytic silica nanoreactors.

Silica-based nanostructures are among the most utilized materials. However, a persistent challenge is their irreversible agglomeration upon drying and heat treatments, restricting their homogeneous colloidal re-dispersion - a mandatory requirement for diverse bio-applications. We address this bottleneck by developing a self carbo-passivation (SCP) strategy: silica nanoparticles (NPs), pre-included with the catalytic metal precursors and organosilanes undergo thermochemical conversion with highly controlled interior-to-surface segregation of nanometer-scale "carbonaceous skin patches".

Neuroplastic Responses to Chiropractic Care: Broad Impacts on Pain, Mood, Sleep, and Quality of Life.

Objectives: This study aimed to elucidate the mechanisms of chiropractic care using resting electroencephalography (EEG), somatosensory evoked potentials (SEPs), clinical health assessments (Fitbit), and Patient-reported Outcomes Measurement Information System (PROMIS-29).

Methods: Seventy-six people with chronic low back pain (mean age ± SD: 45 ± 11 years, 33 female) were randomised into control ( = 38) and chiropractic ( = 38) groups. EEG and SEPs were collected pre and post the first intervention and post 4 weeks of intervention.

Appraisal of malachite green biodegradation and detoxification potential of laccase from Trametes cubensis.

The laccase from the newly isolated Trametes cubensis was investigated for its potential to degrade malachite green (MG) dye. Optimized solid-substrate fermentation enhanced laccase production by 8.8-fold, reaching an activity of 6577.
