Self-incompatibility in Solanaceae is controlled by a single multiallelic locus, the S-locus. The S-allele associated ribonucleases (S-RNases) in the pistil are involved in pollen rejection. In this work, we analyzed two newly isolated lines of Petunia hybrida, termed PB and PF. They both had the same set of S-RNases (SB1- ...

Home pregnancy test kits are more sensitive than many pregnancy kits used in laboratories or health centres. Nurses should know the sensitivity of the kit used in their centre or laboratory. A positive home pregnancy test should always be treated as the correct result until sufficient tests have been carried ...

Nausea and vomiting during pregnancy affect approximately 50% to 70% of all pregnant women. Although most cases of nausea and vomiting in pregnancy resolve spontaneously and are not associated with compromised nutritional status, a small percentage of cases progress to hyperemesis gravidarum (severe nausea and vomiting during pregnancy). Hyperemesis gravidarum ...

Attachment of Fusobacterium nucleatum to various oral surfaces is mediated by several adhesins anchored on its outer surface. Monoclonal antibodies (MAbs) were prepared and used to identify the putative galactose-binding adhesin of F. nucleatum PK1594. Four unique MAbs, 8G7, 26B9, 28G11, and 29D4, were isolated on the basis of their ...

The anterior processes of snakes may transfer odorants from the tongue to the vomeronasal (VN) organ. To test whether the anterior processes are required for a vomeronasally mediated behavior, the authors tested garter snakes (Thamnophis sirtalis) preoperatively and after cauterization of the anterior processes or control cauterization with artificial earthworms ...

We report a documented case of rubella reinfection during pregnancy in a previously vaccinated woman with residual antibody titre to rubella of 15 IU/ml. The reinfection occurred following an exposure to rubella virus (contact with 6-year-old daughter with clinical rubella) between the 7th and 10th week of pregnancy which resulted ...

Pharmacologic stimulation during head-up tilt test (HUT) is used to increase the diagnostic yield of the test to detect vasovagal syncope. Reported lack of specificity of stimulation with intravenous isoproterenol has made a pharmacologic alternative desirable. Because nitrates are known to cause syncope of a vasovagal origin, we administered sublingual ...

(+)-(R)- and (-)-(S)-salsolinol, dopamine-derived tetrahydroisoquinolines, were tested as substrates of pig brain soluble and membrane-bound catechol-O-methyltransferase (COMT) and as inhibitors of O-methylation of dopamine by soluble COMT in vitro. Methylation products were separated by high-performance liquid chromatography with electrochemical detection. Quantification of the products showed that O-methylation of (+)-(R)-salsolinol by ...

Pregnancy induces several haemostatic perturbations. Some authors described possible acquired activated protein C resistance (APCR) during normal pregnancy. We wanted to test this possibility and to evaluate if this acquired APCR might contribute to the known increased tendency to thrombosis associated with pregnancy. To answer the first hypothesis, we tested ...

Two cases of Coxsackie B viral meningo-encephalitis in pregnant women are described. Both patients recovered well and delivered healthy babies, but because of delay in establishing the aetiology of their infections both mothers, and one child, received acyclovir therapy. The differential diagnosis of non-pyogenic meningo-encephalitis in late pregnancy can present ...

We have reviewed our patch test results for preservative allergy from 1982 to 1993. 8 preservatives were included: formaldehyde, 2-bromo-2-nitropropane-1,3-diol (Bronopol(TM)), quaternium-15 (Dowicil 200TM), imidazolidinyl urea (Germall 115TM), diazolidinyl urea (Germall IITM), parabens, 5-chloro-2methyl-isothiazolin-3-one (Kathon CG(TM)) and 1,2-dibromo-2,4-dicyanobutane (one of the constituents of Euxyl K 400TM). Whereas the allergy rate ...

This study compared two Rorschach administration methods across a number of test variables. With a within-subjects, counter-balanced design, 20 female subjects randomly received either an initial Rapaport (Rapaport, Gill, & Schafer, 1968) or an Exner (Exner, 1974, 1986) Rorschach administration. Results showed that the Exner administration produced significantly more Color ...

Melatonin is a weak dose-independent lightening agonist in fish skin, a moderate dose-dependent lightening agonist in toad skin and a potent lightening agent in frog and lizard skins (reversing in a dose-dependent manner the darkening caused by alpha-melanocyte-stimulating hormone). In frog skins, previous exposure to melatonin reduced further lightening actions ...

BACKGROUND: Rubella virus may be transmitted to the fetus following rubella reinfection in early pregnancy. The mechanisms responsible for maternal-fetal transmission in women with pre-existing rubella antibodies are, however, unclear. OBJECTIVES: To evaluate the protective role of rubella specific neutralising antibodies and cell-mediated immunity in rubella reinfection. STUDY DESIGN: Rubella ...

This article describes two gravid patients who presented with first-trimester sialorrhea and hyperemesis. Although excessive salivation, especially when accompanied by protracted nausea and vomiting, is an unusual occurrence, it can have serious consequences for both the mother and fetus when left untreated. Initially, phenothiazine was prescribed and later belladonna alkaloid ...

Hyperemesis gravidarum is a potentially dangerous disorder of pregnancy characterized by severe and protracted vomiting. It is suggested that psychosocial factors may have a role in determining whether the pregnant woman experiences a transient spell of mild vomiting or progresses towards the much rarer but more significant pernicious vomiting. Psychotherapy, ...

The prevalence of bacteriuria in Pakistani women and its association with complications of pregnancy was studied. Out of 1579 women, 77 had bacteriuria (4.8%). There was no association of age, gravidity, parity, haemoglobin, pre-eclampsia, mode of delivery, gestational age at delivery, preterm delivery and low birth-weight with presence of bacteriuria. ...

The causes of nausea and vomiting in pregnancy are still not clearly understood, nor is there one simple, effective treatment. Nausea and vomiting do not appear to be associated with fetal morbidity, malnutrition or death. Carbohydrate-rich snacks at frequent intervals seem to provide relief. Health education on healthy sandwiches and ...

Nausea and fatigue are uncomfortable, sometimes almost debilitating, symptoms of pregnancy. Anecdotally, fatigue seems worse as nausea increases. This descriptive correlational study investigated the relationship between nausea and fatigue during early pregnancy. Fifty-one women who received prenatal care at two obstetrics and gynecology nurse-midwifery practices in a large metropolitan area ...

Two replicons were isolated independently from different IncHI1 plasmids. One was isolated from R27, and a second was isolated from pIP522. We demonstrate, by DNA-DNA hybridization experiments, that these maintenance regions are different and that they are specific to, and carried by, all IncHI1 plasmids tested. In view of this ...
