In Situ Detection of Phosphorylated Platelet-derived Growth Factor Receptor β Using a Generalized Proximity Ligation Method

2007

Improved methods are needed for in situ characterization of post-translational modifications in cell lines and tissues. For example, it is desirable to monitor the phosphorylation status of individual receptor tyrosine kinases in samples from human tumors treated with inhibitors to evaluate therapeutic responses. Unfortunately the leading methods for observing the dynamics of tissue post-translational modifications in situ, immunohistochemistry and immunofluorescence, exhibit limited sensitivity and selectivity. Proximity ligation assay is a novel method that offers improved selectivity through the requirement of dual recognition and increased sensitivity by including DNA amplification as a…

Epithelial-mesenchymal communication in the pathogenesis of chronic asthma.

2005

Although Th-2-mediated inflammation is a key therapeutic target in asthma, its relationship to altered structure and functions of the airways is largely unknown. In addition to inflammation, asthma is a disorder involving the airway epithelium that is more vulnerable to environmental injury and responds to this by impaired healing. This establishes a chronic wound scenario that is capable of sustaining chronic inflammation as well as remodeling. This response occurs as a consequence of activation of the epithelial-mesenchymal unit, involving reciprocal activities of growth factors belonging to the fibroblast growth factor, epidermal growth factor, and transforming growth factor-beta familie…

Minimum cause--maximum effect: the travelogue of a bullet.

2010

This case report involves a 57-year-old male, accidentally shot in the chest with a small bore firearm. The bullet entered the left hemithorax, disrupting the left internal mammarian artery. It then penetrated the anterior wall of the right ventricle causing a pericardial tamponade. After leaving the base of the right heart it perforated the diaphragm, the liver, the spleen and the pancreas. Finally, it penetrated the abdominal aorta 3 cm proximally to the coeliac trunk and reached its final position paravertebrally. This case report illustrates that the management of even minimum gunshot wounds requires a maximum variety of surgical skills. Keywords: Thoracoabdominal injury; Shotgun wound;…

Airway remodeling in asthma.

2003

Chronic inflammation and remodeling may follow acute inflammation or may begin insidiously as a low-grade smoldering response, especially in the case of immune reactions. The histologic hallmarks of chronic inflammation and remodeling are as follows: (1) infiltration by macrophages and lymphocytes; (2) proliferation of fibroblasts that may take the form of myofibroblasts; (3) angiogenesis; (4) increased connective tissue (fibrosis); and (5) tissue destruction. It is clear that changes in the extracellular matrix, smooth muscle, and mucous glands have the capacity to influence airway function and reactivity in asthma patients. However, it is not known how each of the many structural changes …

Late consequences of traumatic rupture of the diaphragm.

2013

A 54-year-old man was admitted to our clinic due to elevated γ-glutamyltransferase, without any clinical symptoms. About 25 years ago, he had undergone blunt abdominal and thoracic trauma during an accident. No diagnostic measures or therapy had been performed at that time. Serum bilirubin was normal, but the values for alanine transaminase, aspartate transaminase, and alkaline phosphatase were slightly above the reference range. Sonography of the abdomen revealed dilated intrahepatic bile ducts up to 3 mm in diameter and steatosis of the liver grade I. CT scan and MRI of the thorax and abdomen showed a giant hiatal hernia with transposition of upper abdominal organs into the chest. As the …

The use of triamcinolone combined with surgery in major ear keloid treatment: a personal two stages approach

2015

Background: Keloid is a fibroproliferative disorder characterized by an abnormal deposition of collagen within a wound. Despite an increased understanding of wound healing and collagen metabolism, the exact cause, the clinical behavior, and gold standard of treatment for keloids remain an enigma. There is no one right way of treatment, the results are variable, and the management of ear keloids can be difficult and frustrating both for patients and physicians. Traditional techniques include intralesional steroids, topical applications of silicone, vitamins, and segmental excision by lasers or surgery. The purposes of this article are to review the literature concerning the current therapies…

Comments to the paper "do we really need new medical information about the Turin Shroud?".

2015

Abstract Following the interesting arguments raised in a recent letter to the editor, about a paper recently published in this journal, the authors are happy to take a cue from them to clarify some facts that have not been sufficiently treated for space. After a description of the methods used, arguments regarding a blunt trauma on the right shoulder with consequent dislocation, the position of the hands on the pubis with brachial plexus injury, and the wrist nailing that caused retracted thumbs are discussed in detail.

Global, regional, and national burden of diseases and injuries for adults 70 years and older:systematic analysis for the Global Burden of Disease 201…

2022

AbstractObjectivesTo use data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) to estimate mortality and disability trends for the population aged ≥70 and evaluate patterns in causes of death, disability, and risk factors.DesignSystematic analysis.SettingParticipants were aged ≥70 from 204 countries and territories, 1990-2019.Main outcomes measuresYears of life lost, years lived with disability, disability adjusted life years, life expectancy at age 70 (LE-70), healthy life expectancy at age 70 (HALE-70), proportion of years in ill health at age 70 (PYIH-70), risk factors, and data coverage index were estimated based on standardised GBD methods.ResultsGlo…
