Engineering of 2‐ketoacid Decarboxylases for Production of Isobutanol and Other Fusel Alcohols in Saccharomyces cerevisiae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Isobutanol is a fusel alcohol that can be produced microbially for use as a biofuel or upgraded into sustainable aviation fuel (SAF). A key enzyme in the isobutanol biosynthetic pathway is 2‐ketoacid decarboxylase (KDC), which irreversibly decarboxylates 2‐ketoisovalerate (KIV) to yield isobutyraldehyde.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Nail in Chicken Gizzard [PDF]

Journal of the American Medical Association, 1911
To the Editor: —The following account may prove of interest: I have before me, on my desk, a dried chicken gizzard which has been opened and cleaned in the usual manner. Through the thick part of one half is a round aperture, ⅛ of an inch in diameter—in the dried specimen—at the internal opening and ¼ of an inch in diameter on the external surface ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

How to Fish With Respect: A Transformation of Human‐Fish Relations in Riverside Amazonia

American Anthropologist, EarlyView.
ABSTRACT Riverside inhabitants of the Middle Xingu River Basin, in the Brazilian Amazonia, frequently say that it is important to respect animals and the forest spirits who protect them. In recent decades, however, the development of an iced fish industry in the region has changed what respect means and how it is expressed when it comes to fishing ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

The Content of Dietary Melatonin in 119 Food Items and Its Relationship With Chronic Diseases: Results of the CUME+ Study

Journal of Human Nutrition and Dietetics, Volume 39, Issue 1, February 2026.
ABSTRACT Background Dietary melatonin, naturally occurring in plant‐ and animal‐based foods, has been linked to beneficial effects on sleep, mood and metabolic health. Although evidence suggests that food‐derived melatonin may elevate circulating levels, few studies have assessed its intake through habitual diets or explored associations with chronic ...

Effects of Sodium Butyrate Forms on Carcass Performance, Pulmonary Hypertension, Metabolic Health and Oxidative‐Inflammatory Responses in Broiler Chickens Under Cold Stress at High Altitude

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Encapsulated sodium butyrate outperforms its non‐encapsulated form by enhancing gut health, reducing oxidative stress and pulmonary hypertension and improving carcass yield in broilers exposed to high‐altitude cold stress, offering an effective nutritional strategy for challenging environments.
