Somatotropin and Lactation

open access: yesJournal of Dairy Science, 1987
Somatotropin, which can now be produced by biotechnology, could have an enormous impact on the dairy industry. Milk yield has been increased up to 40% with daily injections of somatotropin. Cows adjust their nutrient intake to support this increase. Somatotropin does not adversely affect cows' health, although all studies to date have been for less ...

Serotonergic and Dopaminergic Function in Neuropsychiatrically Asymptomatic People With HIV on Antiretroviral Therapy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with HIV (PWH) on antiretroviral therapy (ART) still experience neurocognitive dysfunction and accelerated brain volume loss. To assess whether the serotonergic and dopaminergic systems are affected, we used [11C]DASB positron emission tomography (PET) to assess presynaptic serotonergic function and [18F]FDOPA PET to measure ...

Le lait de jument

open access: yesINRAE Productions Animales, 1991
Les juments produisent en quantité importante (environ 15 kg/j pour une jument de 500-600 kg) un lait dont la composition est assez proche du lait de femme et, pour certains constituants, peut être modifiée en particulier par l’alimentation. Ce lait sert

Herbal Formula Yi‐Fei‐Jie‐Du‐Tang Regulates Epithelial‐Mesenchymal Transition and Vasculogenic Mimicry in Lung Cancer via HIF1A‐Mediated Ferroptosis

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Yi‐Fei‐Jie‐Du‐Tang (YFJDT), a traditional Chinese medicine, has shown potential in lung cancer treatment by targeting key pathways. This study explores the mechanisms of YFJDT using bioinformatics, xenograft models, and A549 cells, demonstrating that YFJDT downregulates HIF1A, promotes ferroptosis, and inhibits epithelial‐mesenchymal transition (EMT ...

Niveau et répartition des apports de concentré hivernaux chez la vache laitière. Résultats sur primipares

open access: yesINRAE Productions Animales, 1990
Cent dix neuf vaches laitières en première lactation ayant vêlé en moyenne le 6 décembre ont été utilisées au cours d’un essai conduit 3 années consécutives. Au cours de l’hiver, tous les animaux recevaient une ration de base composée d’ensilage d’herbe (

Probing lactate exchange and compartmentation in Gray Matter via time-dependent diffusion-weighted MRS [PDF]

open access: yesarXiv
Lactate is crucial in the brain, as it is involved in neuronal activity and memory formation. This is thought to be related to the astrocyte-neuron lactate shuttle hypothesis (ANLS), which has been debated for 30 years, not least because it is difficult to measure lactate compartmentation and exchange in vivo.

A mathematical study of the interaction between oxygen and lactate in an in-vivo and in-vitro tumor [PDF]

open access: yesarXiv
Micro-environmental acidity is a common feature of the tumor. One of the causes behind tumor acidity is lactate production by hypoxic cells of the tumor. Hypoxia is a direct result of the establishment of oxygen gradients. It is commonly observed in the tumor in an in-vitro experimental setup and also in-vivo situation.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.
