An internet search was made looking for articles about chemical and physical modalities that are known to induce collagen and elastin formation. Textbooks, independent articles, journals and books on pathology, biochemistry, aesthetic medicine and cosmetic and plastic surgery were used as references. Here, we take a look at various studies, in vitro and in vivo, that lend credence to the products and procedures used in clinical practice to induce neocollagenesis and neoelastinogenesis.

Epigenetic silencing of genes that are important for DNA repair, cell cycle control, apoptosis, and cellular interactions with the extracellular matrix has been causally linked to several subtypes of cancer. Translating this knowledge of the implications of promoter methylation to wide and routine use in clinical pathology laboratories has been more challenging than the case of genetic analyses because epigenetic modifications do not change the underlying sequence of the affected nucleic acid, rendering polymerase chain reaction analysis alone uninformative...

DNA adducts are a measure of internal exposure to genotoxicants and an important biomarker for human risk assessment. However, the employment of DNA adducts as biomarkers in human studies is often restricted because fresh-frozen tissues are not available. In contrast, formalin-fixed paraffin-embedded (FFPE) tissues with clinical diagnosis are readily accessible. Recently, our laboratory reported that DNA adducts of aristolochic acid, a carcinogenic component of Aristolochia herbs used in traditional Chinese medicines worldwide, can be recovered quantitatively from FFPE tissues...

CONTEXT: Historical research on pathology and laboratory medicine services in World War I has been limited. In the Spanish American War, these efforts were primarily focused on tropical diseases. World War I problems that could be addressed by pathology and laboratory medicine were strikingly different because of the new field of clinical pathology. Geographic differences, changing war tactics, and trench warfare created new issues. OBJECTIVES: To describe the scope of pathology and laboratory medicine services in World War I and the value these services brought to the war effort...

Medicines for the treatment of most human pathologies are encumbered by unwanted side effects that arise from the deposition of an effective drug into the wrong tissues. The logical remedy for these undesirable properties involves selective targeting of the therapeutic agent to pathologic cells, thereby avoiding collateral toxicity to healthy cells. Since significant advantages can also accrue by incorporating a therapeutic or imaging agent into a nanoparticle, many laboratories are now combining both benefits into a single formulation...

Understanding the molecular basis of disease requires gene expression profiling of normal and pathological tissue. Although the advent of laser microdissection (LMD) has greatly facilitated the procurement of specific cell populations, often only small amounts of low quality RNA is recovered. This precludes the use of global approaches of gene expression profiling which require sizable amounts of high quality RNA. Here we report a method for processing of snap-frozen tissue to prepare large amounts of intact RNA using LMD...

In December 2009, the American Society for Veterinary Clinical Pathology (ASVCP) Quality Assurance and Laboratory Standards committee published the updated and peer-reviewed ASVCP Quality Assurance Guidelines on the Society's website. These guidelines are intended for use by veterinary diagnostic laboratories and veterinary research laboratories that are not covered by the US Food and Drug Administration Good Laboratory Practice standards (Code of Federal Regulations Title 21, Chapter 58). The guidelines have been divided into 3 reports: (1) general analytical factors for veterinary laboratory performance and comparisons; (2) hematology, hemostasis, and crossmatching; and (3) clinical chemistry, cytology, and urinalysis...

Prevention of injuries and occupational infections in U.S. laboratories has been a concern for many years. CDC and the National Institutes of Health addressed the topic in their publication Biosafety in Microbiological and Biomedical Laboratories, now in its 5th edition (BMBL-5). BMBL-5, however, was not designed to address the day-to-day operations of diagnostic laboratories in human and animal medicine. In 2008, CDC convened a Blue Ribbon Panel of laboratory representatives from a variety of agencies, laboratory organizations, and facilities to review laboratory biosafety in diagnostic laboratories...

In this review, I showed a brief summary of my carrier in multiple special fields (clinical pathologist, anatomical pathologist of lung, respiratory physician and infection control doctor), my studies and my own view of laboratory medicine. We chiefly study pathology of the lung, especially about type II pneumocytes. Type II pneumocytes had abundant surface coat on the apical surface containing a specific carbohydrate structure of Thomsen-Friedenreich (TF) antigen. TF antigen is a marker of type II pneumocytes beyond animal species, and can be used for evaluating activity of various interstitial pneumonia as type II pneumocyte index (number/lmm alveolar length)...

OBJECTIVES: The objectives of the H1N1 2009 serological surveillance project were twofold: to document (1) the prevalence of cross-reactive antibodies to H1N1 2009 by age group in the population of England prior to arrival of the pandemic strain virus in the UK and (2) the age-specific incidence of infection by month as the pandemic progressed by measuring increases in the proportion of individuals with antibodies to H1N1 2009 by age. METHODS: Residual aliquots of samples submitted to 16 microbiology laboratories in eight regions in England in defined age groups in 2008 and stored by the Health Protection Agency serological surveillance programme were used to document age-stratified prevalence of antibodies to H1N1 2009 prior to the arrival of the pandemic in the UK...

During the nineteenth century the analysis of urine was based on technical tools for the quantification of its constituents. The transformation of diagnostic signs into numbers made reference and normal values indispensable for the verification of the transition point between "normal" and "pathological". It needed the reconfiguration of disease concepts to link measured data and values with specific clinical pictures. Ontological disease concepts were replaced by a gradual understanding of health and disease...

BACKGROUND: Physiological changes during pregnancy may affect laboratory parameters. Reference values based on samples from non-pregnant women are not necessarily useful for clinical decisions during pregnancy. There is a need to establish reference values during pregnancy in order to recognize pathological conditions. METHODS: Eight hundred and one women with expected normal pregnancies were included in the study. Of these, 391 had no complications during pregnancy, delivery, or the early postpartum period...

Circa 1660 several favorable factors, instrumental to the invention of neurology, converged at the University of Oxford. Animals and men were believed to have a material soul whose functions throughout the nervous system were accessible to research. In 1659 inductive methods were introduced in clinical medicine by Thomas Willis, the founder of English epidemiology and biochemistry. The Vertuosi,who later founded the Royal Society, performed chemical experiments in teams, and Willis, head of their laboratory, gained experience in teamwork...

Saliva has become an important resource for evaluating physiological and pathological conditions in humans. The use of saliva has many advantages, including the simple and non-invasive method of collection and its easy, low-cost storage. With the addition of modern techniques and chemical instrumentation equipment, there has been an increase in its use for laboratory investigations, applicable for basic and clinical analyses in the fields of medicine and dentistry. The value of these methods for the diagnosis of oral and systemic diseases has been the subject of study by several researchers with the aim of increasing its use alongside complementary exams...
