Creating focal lesions in primary visual cortex (V1) provides an opportunity to study the role of extra-geniculo-striate pathways for activating extrastriate visual cortex. Previous studies have shown that more than 95% of neurons in macaque area V2 and V3 stop firing after reversibly cooling V1. However, no studies on long term recovery in areas V2, V3 following permanent V1 lesions have been ...
HIV-1 infection is characterized by an ongoing replication leading to T-lymphocyte decline which is paralleled by the switch from CCR5 to CXCR4 coreceptor usage. To predict coreceptor usage, several computer algorithms using gp120 V3 loop sequence data have been developed. In these algorithms an occupation of the V3 positions 11 and 25, by one of the amino acids lysine (K) or arginine (R), is a...
OBJECTIVE The false-positive rate (FPR) is a percentage-score provided by Geno2Pheno-algorithm indicating the likelihood that a V3-sequence is falsely predicted as CXCR4-using. We evaluated the correlation between FPR obtained by V3 population-sequencing and the burden of CXCR4-using variants detected by V3 ultra-deep sequencing (UDPS) and Enhanced-Sensitivity Trofile assay (ESTA). METHODS 54...
Cubic bipartite graphs with girth at least 6 correspond to symmetric combinatorial (v3) configurations. In 1887 V. Martinetti described a simple reduction method which enables one to reduce each combinatorial (v3) configuration to one from the infinite set of so-called irreducible configurations. The aim of this paper is to show that a slightly extended set of reductions enables one to reduce e...
سابقه و هدف: علت اصلی پاتولوژیک بسیاری از بارداری های منجر به سقط همچنان ناشناخته مانده است. hla-g4 (human leukocyte antigen) و hla-g5 دو ایزوفرم غشایی (g4) و محلول (g5) از مولکول های غیر کلاسیک کلاس ib می باشند که در ایجاد تحمل بین مادر و جنین نقش دارند. در این مطالعه بیان این دو ایزوفرم و نیز بررسی تفاوت میزان تأثیر بیان هر آنتی ژن در زنان باردار تهدید به سقط در مقایسه با گروه شاهد ارزیابی شد...
Let Cp denote the cyclic group of order p where p ≥ 3 is prime. We denote by V3 the indecomposable three dimensional representation of Cp over a field F of characteristic p. We compute a set of generators, in fact a SAGBI basis, for the ring of invariants F[V3 ⊕ V3]p . Our main result confirms the conjecture of Shank[15], for this example, that all modular rings of invariants of Cp are generate...
We investigated the functional properties of neurons in extrastriate area V3. V3 receives inputs from both magno- and parvocellular pathways and has prominent projections to both the middle temporal area (area MT) and V4. It may therefore represent an important site for integration and transformation of visual signals. We recorded the activity of single units representing the central 10 degrees...
Re: Discrete alterations in the BZLF1 promoter in tumor and non-tumor-associated Epstein-Barr virus.
In their recent article, Gutiérrez et al. (1) identified three Epstein–Barr virus (EBV) variants in the BZLF1 promoter Zp (Zp-P [considered the prototypical sequence], Zp-V3, and Zp-V4) and postulated that these might result in different lytic potentials and be differentially expressed among individuals with nonmalignant and malignant diseases. Hong Kong and Southern China are considered to be ...
OBJECTIVE We sought to investigate the incidence of complications associated with V2 Guideliner, understand the mechanisms and evaluate the impact of alterations made to the V3 Guideliner. METHODS Retrospective analysis of consecutive cases employing V2 Guideliner from two university teaching hospitals. Complications were identified, analysed and classified into major versus minor ones. To un...
