Objective: To investigate the feasibility of identifying and measuring the normal sacral plexus (SP) on gynecological transvaginal ultrasound (TVS) examination.

Methods: This was a prospective observational study conducted at a single tertiary gynecological referral center, including consecutive women undergoing TVS for various indications between November 2021 and January 2022. A standardized assessment of the pelvic organs was performed and the presence of any congenital or acquired uterine pathology or ovarian abnormality was recorded.

Some considerations on the dependence to numerical schemes of Lagrangian radionuclide transport models for the aquatic environment.

Lagrangian models present several advantages over Eulerian models to simulate the transport of radionuclides in the aquatic environment in emergency situations. A radionuclide release is simulated as a number of particles whose trajectories are calculated along time and thus these models do not require a spatial discretization (although it is always required in time). In this paper we investigate the dependence of a Lagrangian model output with the grid spacing which is used to calculate concentrations from the final distribution of particles, with the number of particles in the simulation and with the interpolation schemes which are required because of the discrete nature of the water circulation data used to feed the model.

Microbiomes in supragingival biofilms and saliva of adolescents with gingivitis and gingival health.

Background: Important alterations exist in the microbiomes of supragingival biofilm and saliva samples from adolescent patients developing induced or spontaneous gingivitis relative to healthy controls. These and the relationships to dental health are not fully understood yet.

Subjects And Methods: Supragingival biofilm samples (n = 36) were collected from the teeth of 9 adolescents with gingivitis induced by orthodontic appliances, as well as dental plaques (n = 40) from 10 adolescents with spontaneous gingivitis, in addition to similar samples (n = 36) from 9 healthy controls.

Application of intraoral scanner to identify monozygotic twins.

Background: DNA base identification is a proper and high specificity method. However, identification could be challenged in a situation where there is no database or the DNA sequence is almost identical, as in the case of monozygotic (MZ) twins. The aim of this study was to introduce a novel forensic method for distinguishing between almost identical MZ twins by means of an intraoral scanner using the 3D digital pattern of the human palate.

ESTE-DECISION SUPPORT SYSTEM FOR NUCLEAR AND RADIOLOGICAL ACCIDENTS.

Described are functions, models and approaches of software tool Emergency Source Term code (ESTE), which is decision support system for crisis staff in case of nuclear or radiological accidents. The first task of ESTE in emergency situation at nuclear facility is to evaluate state of reactor core or state of fuel in spent fuel pool, on the base of state of barriers which should prevent the release of radionuclides to the environment. The main task is to prepare outputs, which can be utilised for recommendation of protective measures.

Fukushima Cs releases dispersion modelling over the Pacific Ocean. Comparisons of models with water, sediment and biota data.

A number of marine radionuclide dispersion models (both Eulerian and Lagrangian) were applied to simulate Cs releases from Fukushima Daiichi nuclear power plant accident in 2011 over the Pacific at oceanic scale. Simulations extended over two years and both direct releases into the ocean and deposition of atmospheric releases on the ocean surface were considered. Dispersion models included an embedded biological uptake model (BUM).

Does the use of reference organisms in radiological impact assessments provide adequate protection of all the species within an environment?

Non-human biota in radiological risk assessment is typically evaluated using Reference Organisms (ROs) or Reference Animals and Plants (RAPs), for all exposure situations. However, it still remains open whether the use of an increased number of species would improve the ability to demonstrate protectiveness of the environment. In this paper, the representativeness of a broader list of fauna is tested in terms of the geometrical characteristics and habits for radiological risk assessments in the case of routine discharges from a nuclear installation: the Cadarache centre.

alpha2B-adrenoceptor agonist ST-91 antagonizes beta2-adrenoceptor-mediated relaxation in rat mesenteric artery rings.

We sought an isolated vascular preparation and experimental setting where the function of alpha2B-adrenoceptors could be demonstrated by non-recombinant technique. ST-91 (2-[2,6-diethylphenylamino]-2-imidazoline), an alpha 2B-adrenoceptor agonist with a mixed alpha adrenergic receptor type/subtype selection profile antagonized the relaxant effect of isoproterenol in endothelium-denuded rat mesenteric artery rings precontracted with phenylephrine. At 10(-7) M of ST-91, the antagonism was characterized by a rightward shift of isoproterenol dose-response curve (A50=6.

Functional order of assembly of herpes simplex virus DNA replication proteins into prereplicative site structures.

Herpes simplex virus replicates its DNA within nuclear structures called replication compartments. In contrast, in cells in which viral DNA replication is inhibited, viral replication proteins localize to punctate structures called prereplicative sites. We have utilized viruses individually mutated in each of the seven essential replication genes to assess the function of each replication protein in the assembly of these proteins into prereplicative sites.

The herpes simplex virus type 1 regulatory protein ICP0 enhances virus replication during acute infection and reactivation from latency.

ICP0 is a potent activator of herpes simplex virus type 1 gene expression in transient assays and in productive infection. A role for ICP0 in reactivation from latency in vivo has also been suggested on the basis of the observation that viruses with mutations in both copies of the diploid gene for ICP0 reactivate less efficiently than wild-type virus. Because the ICP0 gene is contained entirely within the coding sequences for the latency-associated transcripts (LATs), ICP0 mutants also contain mutations in LAT coding sequences.

Ras controls coupling of growth factor receptors and protein kinase C in the membrane to Raf-1 and B-Raf protein serine kinases in the cytosol.

A dominant negative mutant of Ras, M17 Ras, was used to study the role of Ras in receptor coupling of Raf-1 and B-Raf protein serine/threonine kinases (PSKs). We found that mutant Ras blocks serum- and 12-O-tetradecanoyl phorbol 13-acetate-induced activation of Raf-1 kinase in NIH3T3 cells and Raf-1 as well as B-Raf PSK stimulation by nerve growth factor (NGF) in PC12 pheochromocytoma cells. Mitogen stimulation of Raf kinase was measured by determination of Raf hyperphosphorylation and activity towards exogenous substrates and both of these events were inhibited in cells expressing M17 Ras.

In vivo phosphorylation and membrane association of the fyn proto-oncogene product in IM-9 human lymphoblasts.

The protein product of the src-related proto-oncogene, fyn, was isolated from IM-9 cells with antibodies specific for the amino-terminal 22 residues of the fyn protein. Peptide mapping demonstrated that the fyn protein was distinct from the closely related c-src and c-fgr proteins. The fyn protein from IM-9 cells incorporated [3H]myristate in vivo and was found to be membrane associated.
