Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

open access: yesThe FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

open access: yesThe FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...

Evaluating RNAlater® as a preservative for using near-infrared spectroscopy to predict Anopheles gambiae age and species. [PDF]

open access: yes
Mosquito age and species identification is a crucial determinant of the efficacy of vector control programmes. Near-infrared spectroscopy (NIRS) has previously been applied successfully to rapidly, non-destructively, and simultaneously determine the age ...

Towards an integrated molecular understanding of plant hormones

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

The Efficacy of Food‐Grade Substances to Protect Dietary Glutamine From Ruminal Degradation

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to investigate the use of four, low cost, food‐grade substances to protect glutamine from microbial degradation in vitro, and subsequently validate their efficacy in vivo. Two in vitro trials were conducted using 250 mL bottles replicated in triplicate to test beeswax‐, paraffin wax‐, zein‐, and rice bran wax ...

Cuticular Hydrocarbons as Sex Pheromone of the Bee Colletes cunicularius and the Key to its Mimicry by the Sexually Deceptive Orchid, Ophrys exaltata [PDF]

open access: yes, 2018
Male Colletes cunicularius bees pollinate the orchid, Ophrys exaltata, after being sexually deceived by the orchid's odor-mimicry of the female bee's sex pheromone. We detected biologically active volatiles of C. cunicularius by using gas chromatographic-
