Projective linear groups as maximal symmetry groups

A maximal symmetry group is a group of isomorphisms of a three-dimensional hyperbolic manifold of maximal order in relation to the volume of the manifold. In this paper we determine all maximal symmetry groups of the types PSL(2, q) and PGL(2, q). Depending on the prime p there are one or two such groups with q=pk and k always equals 1, 2 or 4.

Childhood sexual abuse. Women's health when starting in group therapy

Childhood sexual abuse has been shown to be common among adult women, 15-30% in prevalence studies, and among mentally ill women, 25-77%. These women often suffer from depression, anxiety, sexual and relationship problems. Suicide attempts and self-destructive behaviour are common. Within the Department of Psychiatry at Lund University Hospital, 45 women with experiences of childhood sexual abuse

Activation of latent protease function of pro-hK2, but not pro-PSA, involves autoprocessing

BACKGROUND: Human glandular kallikrein 2 (hK2) and prostate-specific antigen (PSA) are members of an extensive kallikrein family of proteases. Both proteases are secreted as zymogens or proenzymes containing a seven amino acid propeptide that must be proteolytically removed for enzymatic activation. The physiological proteases that activate pro-hK2 and pro-PSA are not known. METHODS: The pro-hK2 p

Rapid induction of apoptosis in B-cell lymphoma by functionally isolated human antibodies

Novel panning and screening methodology was devised to isolate high affinity human recombinant scFv antibody fragments with functionally associated properties in B lymphoma cells. The approach was used to generate a panel of apoptosis-inducing antibodies specific for antigens differentially expressed in B lymphoma vs. T leukaemia cells. The selections resulted in an antibody pool with near perfect

Formation of highly hygroscopic soot aerosols upon internal mixing with sulfuric acid vapor

The hygroscopic properties of submicron soot particles during internal mixing with gaseous sulfuric acid have been investigated using a combined tandem differential mobility analyzer (TDMA) and differential mobility analyzer-aerosol particle mass analyzer (DMA-APM) technique. Fresh particles exhibit no change in mobility size and mass at subsaturated conditions, whereas particles exposed to gaseou

The Cell Physiology of Biphasic Insulin Secretion

Glucose-stimulated insulin secretion consists of a transient first phase followed by a sustained second phase. Diabetes (type II) is associated with abnormalities in this release pattern. Here we review the evidence that biphasic insulin secretion reflects exocytosis of two functional subsets of secretory granules and the implications for diabetes.

Separation of lactic acid-producing bacteria from fermentation broth using a ceramic microfiltration membrane with constant permeate flow

The influence of several operating parameters on the critical flux in the separation of lactic acid-producing bacteria from fermentation broth was studied using a ceramic microfiltration membrane equipped with a permeate pump. The operating parameters studied were crossflow velocity over the membrane, bacterial cell concentration, protein concentration, and pH. The influence of the isoelectric poi

Determining Critical Process Parameters and Process Robustness in Preparative Chromatography - A Model-Based Approach

This paper presents a model-based method to aid in the process validation for the purification of pharmaceutical drugs. The critical process parameters are identified by simulating process disturbances, and this information is then used to determine if the process control space is robust. Simulations are chosen to analyze the entire control space to also find nonlinearities and interaction effects

Transition probabilities for some spectral lines of N III

Transition probabilities based on sophisticated configuration-interaction wave functions have been obtained for transitions between the 20 lowest lying fine-structure levels of the 2s(2)2p, 2s2p2, 2p3, 2s(2)3s, 2s(2)3p and 2s(2)3d states of N III. The calculations were performed using the CIV3 code of Hibbert, and small empirical adjustments were introduced to the diagonal Hamiltonian matrix eleme

Value at Risk with time varying variance, skewness and kurtosis-the NIG-ACD model

A new model for financial returns with time varying variance, skewness and kurtosis based on the Normal Inverse Gaussian (NIG) distribution is proposed. The new model and two previously suggested NIG models are evaluated by their Value at Risk (VaR) forecasts on a long series of daily Standard and Poor's 500 returns. All three models perform very well compared with extant models and clearly outper

Delay between fusion pore opening and peptide release from large dense-core vesicles in neuroendocrine cells.

Peptidergic neurotransmission is slow compared to that mediated by classical neurotransmitters. We have studied exocytotic membrane fusion and cargo release by simultaneous capacitance measurements and confocal imaging of single secretory vesicles in neuroendocrine cells. Depletion of the readily releasable pool (RRP) correlated with exocytosis of 10%-20% of the docked vesicles. Some remaining ves

Adolescents with alpha1-antitrypsin deficiency have high alpha2-macroglobulin and low neutrophil lipocalin and elastase levels in plasma

Eighteen-year-old adolescents with alpha1-antitrypsin (alpha1AT) deficiency have mostly normal lung function tests. We hypothesized that compensatory increases in other protease inhibitors and/or a decreased leukocyte activity might favorably affect the protease/protease-inhibitor balance in alpha1AT-deficient adolescents. At the age of 18 y 46 PiZZ (severe deficiency), 22 PiSZ (moderate deficienc

Radiative lifetime measurements of even-parity levels of singly ionized erbium

Radiative lifetime measurements were performed by time-resolved laser-induced fluorescence (LIF) technique for eight even-parity levels of the astrophysically important ion Er+ over the energy range from 33753 to 55317 cm(-1). Free erbium ions were generated by a laser-induced plasma. A narrow bandwidth UV laser pulse (1 ns) was employed to populate selectively the short-lived upper levels, and th

The Medical ANtiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation (MANTRA-PAF) Trial: clinical rationale, study design, and implementation

No large randomized multicentre trial has evaluated the efficacy of radiofrequency ablation (RFA) vs. anti-arrhythmic drug (AAD) therapy as a first-line treatment of paroxysmal atrial fibrillation (AF). The Medical ANtiarrhythmic Treatment or Radiofrequency Ablation (MANTRA-PAF) trial is a randomized, controlled, parallel group, multicentre study designed to test whether catheter-based RFA is supe

Effects and serum levels of glibenclamide and its active metabolites in patients with type 2 diabetes

Objective: To study the effects and serum levels of glibenclamide (Gb) and its active metabolites in patients on chronic Gb medication on different daily doses. Material and methods: Fifty patients with type 2 diabetes on regular Gb therapy (1.75-14.0 mg daily). Blood samples were taken immediately before and 90 min after regular Gb intake. A standardized breakfast was served 30 min after drug int

An office procedure to detect vestibular loss in children with hearing impairment

As coexisting vestibular and cochlear lesions are of etiological importance, evaluation of children with congenital or early acquired hearing impairment (HI) should include vestibular assessment. A rotation test requires specific equipment and allows only detection of bilateral vestibular impairment. An impulse or head thrust test allows assessment of one ear at a time, detects more pronounced cal
