Isolation of Human Monoclonal scfv Antibody Specifically Recognizing the D2-5-Ht1a Heteromer.

Abstract:

Antibody phage display has become a useful technique for discovering and optimizing target-specific monoclonal antibodies suitable for many applications, including therapeutic ligands, which may act as direct pharmacological compounds or may be used as targeting ligands for controlled drug delivery. Recently, the D2-5-HT1A heteromer, which is formed by the dopamine D2 and serotonin 5-HT1A receptors has attracted attention as a potential target of antipsychotic drugs. Therefore, the aim of the study was to identify scFv monoclonal antibodies that are able to specifically recognize epitopes formed within the heteromer structure. Because both receptors are membrane proteins, it is important to conduct bio-panning experiments in the most natural conditions, in which the presented antigens (D2-5-HT1A heteromers) are in their native form and possibly in their best-preserved spatial struc...

Exploring the Feasibility of Supporting UK Partners Living Alongside Veterans with PTSD: A Pilot Study of the Together Programme (TTP)

Abstract:

Background

Romantic partners living alongside veterans with Post Traumatic Stress Disorder (PTSD) appear at increased risk of secondary traumatic stress (sPTSD) and common mental health difficulties (CMD) compared to the general population.  The severity of symptoms implies the need for structured, bespoke and evidence-based interventions.

Objective

The aim of this study was to explore the feasibility of offering a community support programme (The Together Programme, TTP) for military partners. TTP was developed based upon a number of US programmes and consisted of 10 hours of group-based support delivered over a five-week course. 56 participants engaged in TTP over a year at nine locations across the UK and were followed up three months later.

Postmenopausal women are at an increased risk of Cardiovascular Disease. We aimed to investigate whether this risk differed between individuals with a naturally occurring and other reasons for menopause within a large population-based Iranian sample.

Study Design

A total number of 1763 postmenopausal women (defined by amenorrhea for more than a year, or FSH > 30-40 mIU/ml), 900 of them with a natural menopause and 863 of them with other reasons for menopause caused by (hysterectomy without oophorectomy or one side oophorectomy, hysterectomy with oophorectomy or two side oophorectomy without hysterectomy) were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Biochemical and hematological risk factors were measured in all the subjects and the data were ana...

High-Resolution SD-OCT and EDI-OCT in the Evaluation and Management of Multifocal Serpigenoed Choroditis

Abstract:

Purpose

To describe spectral domain optical coherence tomography (SD-OCT) and enhanced depth image OCT (EDI-OCT) findings of multifocal serpiginoid choroditis (MSC) , including affected layer of retinal involvement, changes at the vitreoretinal interface, and response to therapy.

Methods

A retrospective review of 20 eyes (14 patients) with MSC. Each patient underwent a complete ophthalmologic examination, fundus photography, fundus autoflorecence (FAF) and OCT imaging of the affected retina at the initial visit and on each follow-up.

Results

In acute stage, SD-OCT showed hyperreflective areas involving the outer retinal layers which include retinal pigment epithelium (RPE), photoreceptor outer segment tips (POST), inner segment...

Massive Left Atrium from Severe Mitral Stenosis due to Rheumatic Heart Disease: Clinical Images Not Usually Seen in Modern Radiology and Ultrasound

Abstract:

Rheumatic heart disease is becoming far less common in the developed world, and therefore expsoure to its complications are been seen less by clinicians. With the increasing ease of world travel, patients with less commonly seen medical conditions are increasingly presenting to Hospitals requiring management of their complications. We present a case of an elderly lady who was a tourist in Australia, who presented with complications of her rheumatic heart disease, and her subsequent radiological and echocardiographic investigations were a significant surpirse for her treating clinicians.

Early Prediction of Alzheimer’s Disease Using OCT Imaging Technique

Abstract:

Alzheimer’s Disease (AD) is one amongst the overwhelming types of dementia that distresses the brain nerve cells leading to a perpetual loss in memory and creating a lot of difficulties for the family members in caretaking. The prediction of the disease at an earlier stage is a common problem. The most prevalent imaging modalities used for diagnosing AD are Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). They can provide valuable information regarding the changes in internal and external brain regions and activities for diagnosing AD. But the relevant studies made on retina reveals that in addition to brain changes there are some variations on the retina layers of the AD patients. Therefore, the retina can be used as a biomarker for diagnosing AD. There are different techniques available for an eye examination. Most noticeable of them are Fundus Imaging and Optical Coherence...

Validity of the Titmus Vision Screener: A Comparison with the Snellen Chart

Abstract:

Given limited knowledge regarding validity of the Titmus vision screener, we sought to compare visual acuity measurements obtained from the Titmus with that from the Snellen chart and assess the validity properties of the Titmus as a screening instrument to detect vision impairment. Visual acuity was measured in 150 participants recruited from an academic ophthalmology practice, using the Snellen chart as well as the Titmus vision screener. Visual acuities from the Titmus and Snellen were compared and validity of the Titmus vision screener was assessed by computing sensitivity and specificity. Using Snellen visual acuity as the reference standard, the sensitivity of the Titmus vision screener to detect vision impairment, defined as visual acuity worse than 20/40, was 92% (95% CI (72.5, 98.6)) and the specificity was 64% (95% CI (57.9, 70.1)). Comparisons of the precise visual acuity level revealed poor agreement between the two methods (weighted Kappa: 0.15, 95% C...

Selective Cytotoxicity of Damsin Derivatives in Breast Cancer Cells

Abstract:

Cancer is the leading cause of death worldwide, and there is a constant need for new treatment strategies. Sesquiterpene lactones containing a 3-methylenedihydrofuran-2(3H)-one (or α-methylene-γ-lactone) moiety, for example damsin (1), are Michael acceptors that affect biological processes such as cell proliferation, death/apoptosis, and cell migration, by interfering with cell signalling pathways. Although the reactivity of the α-methylene-γ-lactone moiety is important for these effects, the Michael addition is reversible and it can be assumed that also other parts of the molecules will moderate any given biological activity. In this investigation, the cytotoxicity of 23 -methylene--lactones towards normal breast epithelial MCF-10A cells as well as breast cancer JIMT-1 cells is compared. Most of the investigated compounds are semisynthetic derivatives prepared by the condensation of the natural product damsin (1) w...

Adrenomedullin as a Protein with Multifunctional Behavior and Effects in Various Organs and Tissues

Abstract:

In literature, it has been reported that adrenomedullin, which is generally thought to have vasodilator, natriuretic and diuretic effects, is synthesized in almost all body, especially CNS, vascular muscles and endothelium, heart, liver, lung, kidney, gastric mocosa, intestinal endothelium and various blood cells. It has been found that the possible effects of adrenomedullin can be demonstrated directly or indirectly by means of active mediators, neuropeptides, enzymes and hormones. It is also suggested that it regulates the endocrine system by affecting the hypothalamic-pituitary axis. It increases in heart failure, acute coronary syndromes, hypertensive conditions, cerebrovascular accessory, chronic renal failure and periodontitis and decreases in peptic ulcer and intestinal diseases. However, it is still not clear whether increase/decrease in adrenomedullin level is a cause of a disease or is a result of damage due to an illness. This peptide, which could be th...
