This autoradiographic study demonstrates the distribution of a range of small solutes and macromolecules in the mucosa of the guinea-pig small intestine after intracardiac injection. The substances investigated were: 14C-urea, 3H-mannose, 3H-inulin, and 125I polyvinylpyrrolidone (PVP). Small bowel biopsies were taken at intervals from one to 60 minutes after injection and the tissues processed ...

A study of community barriers vaccine uptake is needed. Purpose: This aimed analyze affecting acceptance in City. Methods: The collected data from 323 City people. Fear pain, doubts about vaccine, perception fe...

Introduction: Trinidad is a small island middle income country with a high prevalence of type 2 Diabetes. As much as 60% of patients are likely to need insulin therapy in the future. The first step in preparing a patient to convert to insulin therapy is to determine barriers to insulin therapy. The aim of this study is determine barriers to initiating insulin therapy in a primary care setting i...

OBJECTIVES To determine the type of joint and soft tissue injections carried out by general practitioners (GPs) in the Bath area and factors affecting activity. METHODS A questionnaire was sent to 360 GPs requesting information on injections carried out during the previous 12 months, referral pathways for injection, barriers to injecting and training. RESULTS We received 251 replies. The co...

BACKGROUND Pre-eclampsia and eclampsia are serious complications of pregnancy and major causes of maternal mortality and morbidity worldwide. According to systematic reviews and WHO guidelines magnesium sulphate injection (MgSO4) should be the first -line treatment for severe pre-eclampsia and eclampsia. Studies have shown that this safe and effective medicine is unavailable and underutilized i...

Pigmented rabbits were given an intravitreous injection of 0.1 ml of various concentrations of test drug, and vitreous fluorophotometry was done 6 and 24 hr after injection. Dibutyryl cyclic adenosine monophosphate (AMP) and 8-bromo-cyclic AMP caused reversible intravitreous fluorescein leakage only at relatively high concentrations. Adrenergic agents that are effective stimulators of adenylate...

Cross-tolerization of T lymphocytes after apoptotic cell uptake by dendritic cells may be involved in self-tolerance maintenance. Furthermore, immunosuppressive properties are attributed to apoptotic cells. This study evaluated the consequences of apoptotic leukocyte administration in a restrictive engraftment model of murine bone marrow (BM) transplantation. Sublethally irradiated recipients r...

BACKGROUND Needle exchange programmes (NEP) provide injection drug users (IDU) with sterile injection equipment and receive used needles in exchange. In this paper we describe the use of new syringes and NEP by IDU and characteristics associated with using NEP in 1993. METHODS Street-recruited IDU were interviewed in five US locations: Atlanta, Philadelphia, Chicago, New York City, and Los An...

Contact resistances often contribute significantly to the overall device resistance in organic field-effect transistors (OFETs). Understanding charge injection at the metal-organic interface is critical to optimizing OFET device performance. We have performed a series of experiments using bottom-contact poly(3-hexylthiophene) (P3HT) OFETs in the shallow channel limit to examine the injection pr...
