Primary Immunodeficiencies: A Field in Its Infancy

Science, 2007
A paradigm shift is occurring in the field of primary immunodeficiencies, with revision of the definition of these conditions and a considerable expansion of their limits. Inborn errors of immunity were initially thought to be confined to a few rare, familial, monogenic, recessive traits impairing the development or function of one or several leukocyte

Primary wound healing in the septic field

The American Journal of Surgery, 1968
Abstract 1. 1. Attention is directed to the apparent low incidence of wound infection after the emergency thoracotomy for cardiac massage is carried out under septic conditions. In the hope of learning some reason for this a group of fifty-four such patients was evaluated, showing the procedure to result in three infections (5.5 per cent). 2.

A technique for field matching in primary breast irradiation

International Journal of Radiation Oncology*Biology*Physics, 1983
The intrinsic divergence of photon beams presents serious matching problems in three-field treatment of the breast and the adjoining supraclavicular area. A method is presented in which appropriate beam blocking combined with suitable isocentric rotation of the treatment couch neutralize the affects of divergence so that proper matching is achieved at ...

Calibration. Primary—Secondary—Field

The Journal of the Acoustical Society of America, 1997
The primary calibration of acoustic and vibration transducers are well standardized and confirmed by a round-robin inter-laboratory test. Secondary calibration is also very common with traceability to primary calibration. Examples of setups for microphone and accelerometer secondary calibration are discussed regarding accuracy, frequency response ...

Visual field loss in primary congenital glaucoma

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2015
To assess the visual field defects in primary congenital glaucoma (PCG) and to identify associated risk factors.In this cross-sectional study visual fields of consecutive PCG patients were examined using Humphery Field Analyzer (HFA) or Goldmann visual field (GVF).

Primary Aldosteronism: A Field on the Move

2016
Primary aldosteronism is the most common form of secondary hypertension, and is highly prevalent in patients with resistant hypertension. The diagnosis of primary aldosteronism in real life is time consuming and might be tricky. The screening for primary aldosteronism (whom to screen and how to screen), the confirmation of the diagnosis (four tests are

VACTERL as primary, polytopic developmental field defects

American Journal of Medical Genetics, 1999
Previously we proposed that the VACTERL association represents a dysmorphogenetic response of the primary developmental field, i.e., polytopic developmental field defects (DFD). As such, it should conform to the essential attributes of a DFD, namely, heterogeneity, homology, and phylogeneity.

High-field MRI of primary gallbladder carcinoma

Gastrointestinal Radiology, 1988
The magnetic resonance (MR) imaging features are described in a case of gallbladder carcinoma presenting as a fungating mass associated with gallstones as well as biliary obstruction due to pancreaticoduodenal lymph node metastasis. The MR findings complemented diagnostic observations made on preoperative sonography and computed tomography of the ...

SPACE-TIME FLUCTUATIONS COUPLED TO PRIMARY FIELDS

Modern Physics Letters A, 1992
The β-functions and the c-function are calculated in a two-dimensional field theory where the coupling parameters are functions of fields. The action of the theory is given by a combination of the Polyakov action for string theory and the Zamolodchikov action for the deformation of conformal field theory.
