Airway exposure to multi-walled carbon nanotubes disrupts the female reproductive cycle without affecting pregnancy outcomes in mice [PDF]

open access: yesParticle and Fibre Toxicology, 2017
Background The use of multiwalled carbon nanotubes (MWCNT) is increasing due to a growing use in a variety of products across several industries. Thus, occupational exposure is also of increasing concern, particularly since airway exposure to MWCNTs can ...

PROGESTERONE AND ESTRADIOL PROFILES DURING ESTROUS CYCLE AND GESTATION IN DWARF GOATS (CAPRA HIRCUS) [PDF]

open access: yesPakistan Veterinary Journal, 2008
Serum progesterone and estradiol profiles during estrous cycle, gestation and parturition in four Dwarf goat females (Capra hircus) were monitored. Blood sampling was carried out daily during estrous cycle and on alternate days during gestation till ...

Amino acids in the uterine luminal fluid reflects the temporal changes in transporter expression in the endometrium and conceptus during early pregnancy in cattle [PDF]

open access: yes, 2014
In cattle, conceptus-maternal interactions are critical for the establishment and maintenance of pregnancy. A major component of this early interaction involves the transport of nutrients and secretion of key molecules by uterine epithelial cells to help

Digital workflows for pathological assessment of rat estrous cycle stage using images of uterine horn and vaginal tissue

open access: yesJournal of Pathology Informatics, 2022
Assessment of the estrous cycle of mature female mammals is an important component of verifying the efficacy and safety of drug candidates. The common pathological approach of relying on expert observation has several drawbacks, including laborious work ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

open access: yes, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Immunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle. [PDF]

open access: yes, 2017
BackgroundThe synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex ...

Involvement of D2-like dopaminergic receptors in contextual fear conditioning in female rats: influence of estrous cycle

open access: yesFrontiers in Behavioral Neuroscience, 2022
Introduction: Dopamine has been increasingly recognized as a key neurotransmitter regulating fear/anxiety states. Nevertheless, the influence of sex and estrous cycle differences on the role of dopamine in fear responses needs further investigation.

Characterization of the Estrous Cycle in Octodon degus [PDF]

open access: yesBiology of Reproduction, 2010
We characterized the reproductive cycle of Octodon degus to determine whether reproductive maturation is spontaneous in juveniles and if ovarian cyclicity and luteal function are spontaneous in adults. Laboratory-reared prepubertal and adult females were monitored for vaginal patency and increased wheel-running.

PROFIL HORMON ESTROGEN DAN PROGESTERON PADA SIKLUS BERAHI KAMBING LOKAL (Estrogen and Progesterone Profile in Aceh Local Goat Estrous Cycle )

open access: yesJurnal Kedokteran Hewan, 2009
The aim of this research was to find out the normal estrogen and progesterone profile in local goat estrous cycle.  Five female Aceh local goats which the criteria clinically in good condition, have been giving birth before, 1.5-3.0 years old, and showed
