Dynamique folliculaire et niveaux plasmatiques de la progestérone chez la brebis Sarde pendant l’anoestrus saisonnier

, 2003
L’activité ovarienne pendant le cycle oestrien de la brebis a été décrite et jusqu’à trois ondes de croissance folliculaires ont été observées (Bister et al., 1999 ; Evans et al., 2000).

Traitement de maîtrise des cycles à base de progestérone (CIDR®) chez la vache : IA systématique ou sur chaleurs observées [PDF]

, 2009
La détection des chaleurs est un des points clé en reproduction bovine. Les protocoles de synchronisation des chaleurs permettent généralement de s’affranchir de cette détection et d’inséminer les vaches systématiquement à un moment prédéterminé.

MPP8 Facilitates DNA DSB Repair via NHEJ to Promote Chemoresistance of TNBC Independent of Methyl‐H3K9 Binding

Advanced Science, EarlyView.
Chemoresistance is often linked to elevated DNA repair. MPP8 is found to promote breast cancer chemoresistance as a novel NHEJ accessory factor independent of its epigenetic functions. Through multiple protein interactions, MPP8 facilitates association of DNAPK and ligase complexes to promote DNA repair progression.

An Engineered Supramolecular Pathway for Enhanced Electrochemiluminescence

Advanced Science, EarlyView.
A supramolecular electrochemiluminescent (ECL) system is presented in which cucurbit[7]uril (CB7) is covalently linked to [Ru(bpy)3]2+, forming a recognition‐responsive emitter. Host‒guest preorganization of tri‐n‐propylamine enables intramolecular ECL, boosting intensity by 162% compared to the standard system.

Progesterone Is Associated With Increased Vasohibin‐2 Expression, Tubulin Detyrosination, and Paclitaxel Sensitivity in PR‐Negative Ovarian Cancer Cells

Cancer Reports
Background Progesterone induces rapid cellular responses in progesterone receptor (PR)‐negative ovarian cancer cells that are consistent with non‐genomic progesterone signaling.

VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

Evolution du taux de progestérone plasmatique au cours du cycle sexuel chez la brebis Djallonké

, 1991
Les chaleurs ont été observées 1 fois par jour chez 11 brebis Djallonké pendant 38 jours consécutifs soit 2 cycles sexuels environ. Durant cette même période, les brebis ont fait l'objet de prélèvements quotidients de sang pour doser la progestérone ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Plasmatic progesterone radioimmunoassay in cow [PDF]

, 1975
peer reviewedLe dosage de la progestérone chez la vache a été réalisé par la méthode radioimmunologique sans purification préalable. Le taux de progestérone varie de 0,60 ng/ml le jour de l'oestrus à 6,4 ng/ml durant la phase d'activité maximale du corps
