Regulation of catalase activity variation of tea tree (Camellia sinensis)

open access: yes浙江大学学报. 农业与生命科学版, 2014
Catalase (CAT) is a protective enzyme responsible for the degradation of hydrogen peroxide before it damages the cellular components. All aerobic organisms and many anaerobic organisms possess it in virtually.

Smith-Lemli-Opitz Syndrome

open access: yesPediatric Neurology Briefs, 1996
Clinical features as specific indicators in the diagnosis of Smith-Lemli-Opitz syndrome (SLOS) and the reliability of ultraviolet spectrophotometry (UVS) as a biochemical screening test were examined by an Italian SLOS Collaborative Group of ...

NOVEL ULTRAVIOLET ABSORBERS DERIVED FROM CASHEW NUT SHELL LIQUID: SPECTROPHOTOMETRIC, IN SILICO AND IN VITRO ASSAYS

open access: yesDrug Analytical Research, 2020
The cashew nut shell liquid (CNSL) constituents were isolated by our group leading to four mixtures and seventeen pure compounds, which had chromophoric groups similar to organic ultraviolet (UV) absorbers.

Quasars and the Big Blue Bump [PDF]

open access: yes, 2004
We investigate the ultraviolet-to-optical spectral energy distributions (SEDs) of 17 active galactic nuclei (AGNs) using quasi-simultaneous spectrophotometry spanning 900-9000 Angstrom (rest frame).

Planetary Nebulae as Probes of Stellar Populations [PDF]

open access: yes, 2006
Planetary nebulae (PNe) have the potential to revolutionize our understanding of extragalactic stellar populations. Indeed, in many systems, bright PNe are the only individual objects identifiable from the ground, and, even more often, they are the only ...

Reddened, Redshifted, or Intrinsically Red? Understanding Near-Ultraviolet Colors of Type Ia Supernovae [PDF]

open access: yes, 2017
Understanding the intrinsic colors of Type Ia supernovae (SNe Ia) is important to their use as cosmological standard candles. Understanding the effects of reddening and redshift on the observed colors are complicated and dependent on the intrinsic ...

Screening of wheat grains enriched with wall-bound phenolic compounds

open access: yesMethodsX, 2023
Phenolic compounds are dominant antioxidant factors in whole grains and are essential quality traits in future breeding programs. We proposed a robust set of methods for extraction, screening, and quantitative analysis of soluble and wall-bound (WB ...

UVB-311 nm phototherapy and NAD(+)/NADH metabolism in keratinocytes in patients with psoriasis

open access: yesPrzegląd Dermatologiczny, 2019
Narrow band (311 nm) UVB phototherapy is established treatment for psoriasis. DNA is a target for UVB via formation of cyclobutane pyrimidine dimers, which trigger loss of dendritic cells and macrophages, and inhibit CD4+ and CD8+ T cells.
