1. Transcriptional profiling of uterine leiomyoma rats treated by a traditional herb pair, Curcumae rhizoma and Sparganii rhizoma
The aim of this study was to elucidate the concise effects of a traditional herb pair, Curcumae rhizoma-Sparganii rhizoma (CRSR), on uterine leiomyoma (UL) by analyzing transcriptional profiling. The UL rat model was made by intramuscular injection of progesterone and gavage administration of diethylstilbestrol. From 11 weeks of the establishment of the mode

2. Response of vital functions, Apgar and cortisol in the prognosis of vigor against neonatal factors of lambs
RESUMO: O manejo dos cordeiros durante o período neonatal tem sido objeto de estudo em diversas pesquisas devido às adaptações orgânicas vitais e hormonais sofridas pela cria após o parto. Todavia, o gênero, número de filhotes e o tipo de parto parecem desempenhar um papel importante para melhor compreensão do vigor neonatal. Além disso, o estudo d

3. Concentração sérica de progesterona, pH da vagina e morfometria corpórea de cervas gestantes (Cervus unicolor) em cativeiro
ABSTRACT The aim was to study pregnant cervus in captivity, to obtain body morphometric data, serum progesterone concentrations, and pH of the vagina. Females of cervus (Cervus unicolor), (n=8) between 2 and 3 years old were used in November during breeding season. After sedation, in one collection, the following was measured: body weight 54.50 ± 18.70kg, b

4. Serum 25-hydroxyvitamin D levels in patients with Granulomatosis with Polyangiitis: association with respiratory infection
OBJECTIVES: To determine the possible association of serum 25-hydroxyvitamin D (25OHD) levels with disease activity and respiratory infection in granulomatosis with polyangiitis patients during two different periods: winter/spring and summer/autumn. METHODS: Thirty-two granulomatosis with polyangiitis patients were evaluated in the winter/spring, and the s

5. Novel immunoassay for TSH measurement in rats
ABSTRACT Measuring thyroid hormones is an important aspect for the study of metabolism and for monitoring diseases in both human and animal models. The traditional method for hormone measurement in rats is the radioimmunoassay (RIA). However, the RIA is associated with some practical disadvantages, including the use of radioactive material, the need for spec

6. Neuropeptide Y, substance P, and human bone morphogenetic protein 2 stimulate human osteoblast osteogenic activity by enhancing gap junction intercellular communication
Bone homeostasis seems to be controlled by delicate and subtle “cross talk” between the nervous system and “osteo-neuromediators” that control bone remodeling. The purpose of this study was to evaluate the effect of interactions between neuropeptides and human bone morphogenetic protein 2 (hBMP2) on human osteoblasts. We also investigated the effects

7. Live weight and metabolic hormone profile in steers moved in drives
The objective was to determine the effects of driving on the growth of steers during 55 days of moving by drive and 84 days after the arrival. Twenty-five steers were randomly chosen from a herd of 1,000 Nellore cattle, which were evaluated in two periods: the driving period, in which animals were moved a distance of 700 km on foot for 55 d; and the post-dri

8. Changes in cardiac aldosterone and its synthase in rats with chronic heart failure: an intervention study of long-term treatment with recombinant human brain natriuretic peptide
The physiological mechanisms involved in isoproterenol (ISO)-induced chronic heart failure (CHF) are not fully understood. In this study, we investigated local changes in cardiac aldosterone and its synthase in rats with ISO-induced CHF, and evaluated the effects of treatment with recombinant human brain natriuretic peptide (rhBNP). Sprague-Dawley rats were

9. Stress in Pimelodus maculatus (Siluriformes: Pimelodidae) at different densities and times in a simulated transport
The transportation of live fish is a routine procedure in aquaculture, and includes a series of stressful stimuli such as an increase in the stocking density of specimens per volume of water, and abrupt changes in water quality. This study evaluated the water quality and the stress levels on Pimelodus maculatus (Lacépède, 1803) fingerlings transported in p

10. Culture of bovine ovarian follicle wall sections maintained the highly estrogenic profile under basal and chemically defined conditions
Follicle cultures reproduce in vitro the functional features observed in vivo. In a search for an ideal model, we cultured bovine antral follicle wall sections (FWS) in a serum-free defined medium (DM) known to induce 17β-estradiol (E2) production, and in a nondefined medium (NDM) containing serum. Follicles were sectioned and cultured in NDM or DM for 24 o

11. Psychological stress alters the ultrastructure and increases IL-1β and TNF-α in mandibular condylar cartilage
Psychological factors can be correlated with temporomandibular disorders (TMDs), but the mechanisms are unknown. In the present study, we examined the microstructural changes and expression of proinflammatory cytokines in mandibular condylar cartilage of the temporomandibular joint (TMJ) in a psychological stress animal model. Male Sprague-Dawley rats (8 wee

12. Correlations of circulating peptide YY and ghrelin with body weight, rate of weight gain, and time required to achieve the recommended daily intake in preterm infants
The objective was to elucidate the relationships between serum concentrations of the gut hormone peptide YY (PYY) and ghrelin and growth development in infants for potential application to the clinical observation index. Serum concentrations of PYY and ghrelin were measured using radioimmunoassay from samples collected at the clinic. For each patient, gestat
