Deciphering the functional role of EGR1 in Prostaglandin F2 alpha induced luteal regression applying CRISPR in corpus luteum of buffalo

Biol. Res; 54 (), 2021
BACKGROUND: PGF2α is essential for the induction of the corpus luteum regression which in turn reduces progesterone production. Early growth response (EGR) proteins are Cys2-His2-type zinc-finger transcription factor that are strongly linked to cellular proliferation, survival and apoptosis. Rapid eleva...

The role of prostaglandin F2α on ovulation and LH release in cows

This study aimed to evaluate the role of prostaglandin F2α (PGF) on ovulation. In Experiment 1, cows were randomly allocated to two treatments to receive 150 μg of d-Cloprostenol (PGF Group, n = 12) or 2 mL of NaCl 0.9% (Control Group, n = 11) and CIDRs, were removed 4 days later. No cow ovulated in...

Endometrial prostaglandin F2α in vitro production and its modulation regarding dominant follicle position in cattle

Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several molecular pathways in endometrial cells, including the synthesis of PGF2α; however, ...

Aumento de estresse oxidativo no sangue de pacientes com ostomia

Arq. gastroenterol; 55 (2), 2018
ABSTRACT BACKGROUND: Ostomy is a surgical procedure that creates a stoma that aims to construct a new path for the output of feces or urine. The relationship of oxidative stress (OxS) markers in patients with ostomy is still poorly described. OBJECTIVE: The present study was aimed at investigating th...

Radioiodine-induced oxidative stress in patients with differentiated thyroid carcinoma and effect of supplementation with vitamins C and E and selenium (antioxidants)

ABSTRACT Objective The objective of this study, in addition to confirming that therapy with 131I causes oxidative stress, was to evaluate the effect of supplementation with vitamins C and E and selenium on this phenomenon by measuring plasma 8-epi-PGF2a, a marker of lipid peroxidation. Subjects and met...

Desempenho reprodutivo de novilhas acasaladas aos 26 meses de idade submetidas a sincronização de estros com pgf2 alfa administrado por via intramuscular ou intravulvar

O objetivo do presente trabalho foi avaliar a resposta reprodutiva de novilhas, aos 26 meses de idade, submetidas à inseminação artificial em estro, observado ao início da estação de acasalamento, seguida de estro induzido por um análogo sintético da PGF2 α administrado por via intramuscular ou ...

Custo do tratamento de drogas antiglaucomatosas: latanoprost, travoprost, bimatoprost e unoprostona isopropílica
Cost of antiglaucoma drug treatment: latanoprost, travoprost, bimatoprost and unoprostone isopropyl

Arq. bras. oftalmol; 66 (6), 2003
OBJETIVO: Determinar o custo do tratamento clínico antiglaucomatoso com drogas de ação úveo-escleral considerando o numero de gotas por frascos, volume médio das gotas assim como a duração máxima do tratamento propiciada por frasco. MÉTODOS: Realizou-se estudo experimental utilizando oito frasco...

Half dose of prostaglandin F2a is effective to induce luteolysis in the synchronization of ovulation protocol for fixed-time artificial insemination in buffalo (Bubalus bubalis)

O objetivo desse estudo foi avaliar a eficiência da meia dose de PGF2alfa no protocolo de sincronização da ovulação (GnRH/PGF2alfa/GnRH) para inseminação artificial em tempo fixo em bubalinos. Foram utilizadas 262 búfalas ( 40 dias pós-parto), divididas em dois grupos (Grupo 1, n = 125, GnRH/ ½...

Cardioplegia cristalóide, barotrauma e funçäo endotelial: consideraçöes experimentais
Crystalloid cardioplegia, barotrauma and endothelium function: experimental considerations

O presente ensaio experimental estudou o efeito da infusao de soluçao cardioplégica cristalóide a altas pressoes sobre a funçao endotelial de artérias epicárdicas de caes. Nao se encontraram alteraçoes a nível de receptores (curvas dose-respostas à ACH e ADP; da transduçao do sinal iniciado nos...
