| The ejaculated semen consists of two major components viz. sperm cells (spermatozoa) and the fluid part obtained after centrifugation called seminal plasma. The spermatozoa originate from the semniferous tubule and are suspended in the seminal plasma. The seminal plasma is composed of secretions contributed by the testis, epididymis, seminal vesicles, ampullae, prostate and bulbourethral glands. About 60-80 % of the ejaculated semen of the bull originates from these sources. Seminal plasma is a highly complex biological fluid containing proteins, amino acids, enzymes, fructose and other carbohydrates, lipids, major... |

| ABSTRACT A new point-of-care HIV viral load, mPIMA HIV-1/2 VL, Abbott, USA, has been recently developed. This point-of-care viral load requires no skilled person to run and uses a small plasma volume (50 µL). However, obtaining 50 µL of plasma can be a challenge in limited resource settings. We validated a simple and easy method to obtain enough amount of plasma to run a point-of-care viral load. The study utilized 149 specimens from patients failing antiretroviral therapy. At least 250 µL of whole blood was collected in a microtube/EDTA from fingerstick (fs-plasma) and immediately centrifuged. Parallel collection of... |

| With the increasing use of artificial insemination techniques, little importance has been given to seminal plasma, since it is substituted by other diluters. However, natural sexual intercourse would not work without seminal plasma as diluter for spermatozoa in the epididimus. The study of seminal plasma brings important information for the research on diluters, which are made to substitute the forme. Thus, if the seminal plasma composition were known, it would be easier to preserve semen samples, specially those of species that present cryopreservation problems. Beside, knowledge on "fertility markers" that may be present... |

| In the present study the upper reference limits (URLs) for resting plasma norepinephrine, epinephrine, serum aldosterone, plasma renin activity, aldosterone/ renin activity ratio, as well as urinary vanillylmandelic acid in healthy Egyptian normotensive subjects over a range of ages (5-60 yr) were established. There was a significant age effect on plasma norepinephrine, UVMA, serum aldosterone and PRA, whereas a single URL for plasma epinephrine level is satisfactory. In uncomplicated untreated essential hypertensive subjects (5-60 yr), the average prevalence of elevation in the plasma... |

| ABSTRACT The purpose of this work was to evaluate the influence of the clinical profile on lamotrigine (LTG) plasma concentrations from patients with refractory epileptic seizures. In this cross-sectional study, therapeutic monitoring of LTG, and questionnaires with 75 patients with refractory epileptic seizures of a Hospital in Ribeirão Preto-SP-Brazil were performed. The multiple linear regression model was used to verify association between the LTG plasma concentrations and the independent variables. Covariance analysis was used to compare the mean LTG plasma concentration among the co-medication groups. The LTG plasma... |

| It is well known that an injection of prostaglandin F2α (PGF2α) or its analogue during the mid luteal phase of the estrous cycle induces a rapid decrease in plasma progesterone (P4) concentration, followed by luteolysis in the cow. There is evidence that a potent vasoactive peptide, endothelin-1 (ET-1), is produced in the bovine corpus luteum (CL), and that it is directly involved in luteolysis. We previously found that ET-1 concentrations in the peripheral plasma increase during the period of luteolysis and ovulation in cows. However, it is not clear whether the elevation of peripheral plasma ET-1 concentration observed during luteolysis and ovulation... |

| Abstract Coronary artery bypass grafting reduces plasma L-carnitine and may impair the production of myocardial energy. L-carnitine supplementation may elevate plasma L-carnitine and increase cardiac mechanical efficiency. The objective of this study was to verify the recovery of preoperative plasma LC in patients with heart failure undergoing coronary artery bypass grafting supplemented with a daily oral dose of 50 mg / kg. Volunteers with ischemic heart failure who underwent surgery were randomized into a supplemented group (A-received 50 mg / kg L-carnitine) or placebo group (B) for 60 days. Supplementation was started on the third postoperative day.... |

| The objective of this study was to evaluate the effects of egg yolk and seminal plasma on the viability of cryopreserved goat semen. To this end, four fertile Saanen bucks, aged between 10 months and 1 year, and weighing 18 to 25 kg, were used. Semen was collected from each buck by the artificial vagina method at the end of breeding season (June-July). The extender used was the yolk citrate, which was split into two equal aliquots: 5% egg yolk (2.5 mL egg yolk: 47.5 mL citrate solution) were added to one of the samples and 10% egg yolk (5.0 mL egg yolk: 45.0 mL citrate solution) were added to another. The sperm motility and vigor after thawing and post thermal resistance test (TRT) were evaluated and the data were... |

| Although HCV has hepatic tropism, the presence of the virus in extra-hepatic compartments has been well documented. Platelets have been described as carriers of the virus in the circulation and may be a natural reservoir for the virus. However, few studies have been performed to evaluate the levels of HCV RNA in plasma and platelets are equal or differ in some way. Therefore, the aim of this study was to perform a comparative evaluation of the stability of HCV RNA in plasma and isolated platelets. Four aliquots of whole plasma obtained from patients infected with HCV were incubated at 37 °C for 0, 48, 96 and 144 h. After incubation, the |

| The purpose of this work was to evaluate the effects of the water-soluble fraction of gasoline (WSFG) on the Neotropical freshwater fish Prochilodus lineatus. The WSFG was prepared by mixing gasoline in water (1:4) and animals were exposed for 6, 24 and 96h to 5% diluted WSFG or only to water. After exposure, blood was collected from the caudal vein and the gills were removed. The following parameters were analyzed: hematological (hemoglobin, hematocrit, number of red blood cells), osmo-ionic (plasma Na+, Cl- and K+ and plasma osmolarity), metabolic (total plasma proteins and glucose), endocrine (cortisol), density and distribution of chloride cells [CC]... |

| OBJECTIVE: One approach to identifying HIV-1 vaccine candidates is to dissect the natural antiviral immune response in treatment-naïve individuals infected for over ten years, considered slow progressor patients (SPs). It is suspected that SP plasma has strongly neutralizing antibodies (NAb) targeting specific HIV viral epitopes. METHODS: NAbs levels of 11 HIV-1-infected SPs were detected by PBMC-based neutralization assays. To investigate SP NAb epitope, this study used a biopanning approach to obtain mimotopes of HIV-1 that were recognized by SP plasma NAbs. IgG was purified from hightiter NAb SP plasma, and used as the ligand for three rounds of... |
