To use Bioengineering methodology is used to achieve, at five anatomical sites, a detailed, quantitative assessment of the return of blood content to the blanched area, during the Capillary Refill (CR) test. An observational, non-randomized, experimental study on 23 healthy subjects (14 females) was performed in our climate controlled skin physiology laboratory. Our main outcome measures were based on the chronological assessment and quantification of red blood cell concentration (RBC) after the release of blanching pressure in the CR test, using Tissue Viability Imaging (TiVi), a digital photographic technique based on polarisation spectroscopy...

Yong Pu, Almudena Veiga-Lopez
BACKGROUND: Although the 3T3-L1 preadipocyte cell line represents an informative model for in vitro adipogenesis research, primary cultured cells are often needed to understand particular human or animal metabolic phenotypes. As demonstrated by in vitro cultured preadipocytes from large mammalian species, primary cultured cells require specific adipogenic differentiation conditions different to that of the 3T3-L1 cell line. These conditions are also species-specific and require optimization steps...

This study aimed to investigate the effect of supplemental camphor on the performance and immune functions of Japanese quail by feeding graded levels (0 (control), 250, 500, 750, 1000, 5000 or 10 000 ppm) of camphor during a 42-day feeding trial. In all, 280 1-day-old quail chicks were randomly assigned into 28 cages of 10 chicks each with separate feeders. The results clearly demonstrated that camphor did not have a significant effect on BW, BW gain, total experimental average daily feed intake, feed conversion ratio, internal organ relative weights and biochemical parameters such as uric acid, albumin, total protein and triglyceride; however, plasma cholesterol concentration was significantly different in a linear manner, in which 500 ppm of camphor resulted in a lower level of cholesterol...

Behçet's disease (BD) is an inflammatory multisystemic disorder associated with orogenital ulcers, uveitis and skin lesions with unpredictable episodes of exacerbations and remissions. Even though several immunological and environmental factors contribute to BD progression, its ethiopathogenesis remains uncertain and elusive. Considered as one of the potent environmental factors that can increase prevalence of some autoimmune and inflammatory disorders, vitamin D deficiency has been linked to several diseases as BD...

INTRODUCTION: Psychological stress is known to cause exacerbation of different skin pathologies including alopecia areata (AA). A hyperactivity of the HPA axis in patients affected by AA (AA-patients) was proposed to be a neuroendocrine response to stress. Still little is known about MSH and cortisol production in AA settings. AIM: The aim of the study was to compare trends in a production of melanocyte-stimulating hormone (MSH) and cortisol in patients with AA-patients and healthy controls...

BACKGROUND: Currently the same allergen concentrations for canine intradermal testing (IDT) are recommended for feline IDT. Feline skin reactions are subtle and more difficult to read than canine reactions. This difference may be due to suboptimal allergen concentrations used for IDT in cats. HYPOTHESIS/OBJECTIVES: To determine the irritant threshold concentration (ITC) of 16 pollen allergens using serial dilutions of allergen and intravenous fluorescein. The hypothesis tested was that feline IDT currently is performed at suboptimal allergen concentrations for pollens...

Haptoglobin exerts renal protective function by scavenging free hemoglobin from the urine and blood stream in patients with hemolytic disorders. Recent studies elucidate the relationships between haptoglobin and inflammation. In addition, coagulopathy is often induced by systemic inflammation characterized by the presence of vascular endothelial damage. We hypothesize that haptoglobin might have an anti-inflammatory effect and affect hypercoagulability using rat burn model. Thirty anesthetized rats of six-weeks of age received over 30% full-thickness scald burn on the dorsal skin surface...

Garlic (Allium sativum L.) is grown all over the world as seasoning and medicinal vegetable since 3,000 BC. Allicin is the main component of garlic, being attributed to it the most of its biological activities, such as bactericidal, antifungal and antiviral actions. However, other compounds of garlic present antioxidant, hypocholesterolemic, vasodilator activities, protective action against different types of cancer, and immunomodulatory. Fungal infections are important causes of morbidity and mortality in people mainly in immunosuppressed ones...
