Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

Plant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.

Effects of Spirulina Enrichment on Bread Quality: Color, Texture, Volatile, and Sensory Properties. [PDF]

Food Sci Nutr
This study explored how the addition of 1%–2% Spirulina powder affects bread quality, focusing on color, texture, volatile compounds, and sensory characteristics. Spirulina mainly influenced bread color and volatile profile, while texture remained largely unchanged. The enriched samples also showed more pronounced bitter and marine notes.

Domino Synthesis of Benzo-fused β,γ-Unsaturated Ketones from Alkenylboronic acids and N-Tosylhydrazone-tethered Benzonitriles [PDF]

, 2019
The transition-metal-free domino reaction between alkenylboronic acids and N-tosylhydrazones from o-(2-oxoalkyl)- and o-(3-oxoalkyl)benzonitriles leads to β,γ-unsaturated indanones and tetralones featuring an α-“all-carbon” quaternary center.

The Mechanisms of Catalysis by Metallo β-Lactamases [PDF]

, 2008
Class B β-lactamases or metallo-β-lactamases (MBLs) require zinc ions to catalyse the hydrolysis of β-lactam antibiotics such as penicillins, cephalosporins, carbapenems, and cephamycins.

Development of In Vitro and In Planta Strategies for Efficient Production of High‐Value Steviol Glycosides

Plant Biotechnology Journal, EarlyView.
ABSTRACT Steviol glycosides (SGs) are a group of sweet‐tasting diterpene glycosides found in Stevia rebaudiana. Production of high‐value SGs, Rebaudioside D (Reb D) and Reb M, is limited by inefficient conversion of Reb A to Reb D and stevioside to Reb E.

The history and analytical chemistry of beer bitter acids

, 1992
The organoleptic characteristics of beer are mainly determined by the bitter-tasting iso-alpha-acids, which in the brewing process are formed from the alpha-acids occurring in hops. Quantification of the individual iso-alpha-acids is not straightforward,

Phenotypic Differentiation Between Highland and Coastal Quinoa Under Cold Stress Conditions

Plant, Cell &Environment, EarlyView.
ABSTRACT Quinoa (Chenopodium quinoa Willd.) is a genetically diverse Andean crop valued for its nutrition and adaptability to varied agro‐climatic conditions with potential for cultivation in European and Mediterranean, particularly on marginal lands. Low temperatures during early sowing can impair germination, while delayed sowing increases the risk ...

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Content of trans- and cis-iso-alpha-bitter acids as indicator of sensorial beer stability.

, 2007
Content of cis- a trans- isomers of iso-α-bitter acids has been studied during beer storage at 8 °C, 20 °C and 30 °C. Stereoisomers of iso-α-bitter acids have been determined in beers by optimised method based on Harms and Nitzsche method.
