Carbon isotopic evidence for the catalytic origin of light hydrocarbons

Geochemical Transactions, 2000
The molecular proportionality between C6 and C7 isomers reported recently (F. D. Mango, Geochim. Cosmochim. Acta, 2000, 64, 1265; ref. 1) is probably the strongest evidence for catalysis yet published. It implicates two cyclopropane-like precursors, [S6]

Instrumental variables estimation of large demand systems with an application to fruit and vegetable demand and price index

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This paper derives the asymptotic properties of an iterated three‐stage least squares (I3SLS) estimator and applies it to estimate a Quadratic Almost Ideal Demand (QUAID) system for 47 fruits and vegetables with endogenous prices. We calculate an exact price index from the estimates and compare it with several commonly used price indexes.

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Advancements on the Mechanism of Soluble Sugar Metabolism in Fruits

Horticulturae
Soluble sugars, primarily fructose, glucose, sucrose, and sorbitol, are crucial determinants of fruit flavor and quality. As a core component of biological metabolism, sugar metabolism provides energy and carbon for fruit development, ultimately ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Polyamine treatments: an effective strategy to improve crop yield and fruit colour and to preserve quality of ‘Mollar de Elche’ pomegranate fruit during storage at chilling temperatures

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change in Spain is altering the optimal conditions for producing high‐quality ‘Mollar de Elche’ pomegranate fruit, due to reduced colour development in husk and arils. In addition, the pomegranate requires storage above 7–10 °C, depending on cultivar, to preserve its quality because it is susceptible to chilling injury (CI ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Traditional Chinese Medicine as an Integrative Adjunct in Oncology Perioperative Practice: Analgesia, Immune Modulation, and Translational Challenges

Medicine Bulletin, EarlyView.
ABSTRACT Traditional Chinese medicine (TCM), including herbal analgesic adjuvants and acupuncture‐based interventions, has gained increasing attention as an integrative strategy for perioperative pain management in oncology. Bioactive phytochemicals—such as terpenoids, flavonoids, alkaloids, and polyphenols—exert multimodal pharmacological effects ...
