The objective of this study was to assess the efficacy of cephapirin intrauterine treatment preceding a timed artificial insemination protocol in lactating dairy cows with purulent vaginal discharges (PVDs). Holstein dairy cows (n = 1247) from 18 herds were enrolled in a controlled randomized clinical trial. At 34 days in milk (DIM; ±7 days), cows had a genital examination (transrectal palpation, vaginoscopy, and uterine bacteriology). They were randomly assigned to either the control group (CONT, no treatment) or the treatment group (CEPH) consisting of 1 intrauterine infusion of 500-mg cephapirin benzathine (RCL) (Metricure, Merck Animal Health, Montreal, Canada) regardless of the uterine health status...

In the context of genito-pelvic pain, consideration of interpersonal goals is particularly relevant given that couples' distress is often predicated upon the relational setting. However, relationship goals have not been examined in this population. We investigated (1) the associations between relationship goals and women's pain during intercourse as well as the sexual, relational, and psychological well-being of women with provoked vestibulodynia (PVD) and their partners and (2) the moderating role of sexual goals in these associations...

Nanocomposite SiOx particles have been produced by a single step plasma spray physical vapor deposition (PS-PVD) through rapid condensation of SiO vapors and the subsequent disproportionation reaction. Core-shell nanoparticles, in which 15 nm crystalline Si is embedded within the amorphous SiOx matrix, form under typical PS-PVD conditions, while 10 nm amorphous particles are formed when processed with an increased degree of non-equilibrium effect. Addition of CH4 promotes reduction in the oxygen content x of SiO x , and thereby increases the Si volume in a nanocomposite particle...

Quantitative evaluation of hindlimb ischemia is essential for early diagnosis and therapy of peripheral arterial disease (PAD). Dynamic imaging using near-infrared (NIR) fluorophore indocyanine green (ICG) is a noninvasive and effective tool to monitor multiple vascular parameters including perfusion rate (PR), perfusion vascular density (PVD) and hemodynamics. It has been previously demonstrated that temperature changes could lead to significant variations of blood flow rate and vascular perfusion. In this paper, multiparametric evaluation of hindlimb ischemia was performed at different temperatures...

Provoked vestibulodynia (PVD)-a recurrent, localized vulvar pain-interferes with couples' sexual relationships as evidenced by lower sexual satisfaction compared to controls. Little is known about what components of sexual satisfaction contribute to this lower satisfaction. Using the Interpersonal Exchange Model of Sexual Satisfaction (IEMSS), we compared the sexual exchanges (sexual rewards and costs, relative sexual rewards and costs, balance of sexual rewards and costs, balance of relative sexual rewards and costs, equality of sexual rewards and costs) and sexual satisfaction of 50 women with PVD and their male partners to 50 matched-control couples...

Peripheral vascular disease (PVD) is a chronic disabling illness that frequently results in the occlusion of arteries in lower limbs and may cause ischemia, gangrene, or infection. The single most significant factor contributing to both the onset and progression of PVD is smoking, which has addictive properties. Once smoking becomes a habitual behavior, combined with the atherosclerotic process, a disastrous pathway ensues. The aim of this project was to gain an understanding of the beliefs of patients with PVD who smoked...
