The response after application of various concentrations of sodium lauryl sulfate (SLS) on human skin is reported. The induced changes associated variable degrees of roughness and erythema characterizing rough dermatitic skin (RDS). These clinical changes were almost invariably (less than 5%
While half of the world's population is at risk of malaria, the most vulnerable are still children under five, pregnant women and returning travelers. Anopheles mosquitoes transmit malaria parasites to the human host; but how Plasmodium interact with the innate immune system remains largely
The versatility of nanoparticle design has established nanotechnology as a potential "one-stop solution" to many biological and medical applications. The capacity to control nanoparticle size, shape, and surface chemistry has enabled their use as imaging contrast agents or carriers for drugs and
Spreading lesions clinically resembling lymphangitic sporotrichosis developed on the right arm and chest of a 60-year-old man with chronic lymphocytic leukemia. Acid-fast bacilli were seen in exudates from lesions and in biopsies, and were cultured from them. The isolant grew initially as a
Current bare metal stents can be improved by nanotechnology to support the simultaneous acceleration of endothelialization and consequent reduction of immune cell responses after implantation. In our prior study, electron beam deposition was utilized to create different scales of roughness on
Lipopolysaccharide (LPS) is the major pathogen-associated molecular pattern of Gram-negative bacterial infections, and includes smooth (S-LPS) and rough (R-LPS) chemotypes. Upon activation by LPS through CD14, TLR4/MD-2 heterodimers sequentially induce two waves of intracellular signaling for
OBJECTIVE
The initial contact of blood with biomaterials and subsequent recruitment of inflammatory and marrow-derived stromal cells are among the first phases of bone regeneration. The aim of this study was to investigate the migratory potential of mesenchymal stem cells by treating rat bone marrow
Besides bone, two other tissues directly contact an osseous implant and/or attachments to it: epithelium and soft connective tissues including the gingival connective tissue. These tissues have received less attention than bone, but are required because of the transmucosal nature of endosseous
The laminated inclusions in the rough endoplasmic reticulum (RER) are peculiar structures seen only in some cases of chondrocytes of pseudoachondroplasia. These ultrastructurally unique organelles have not yet been reported in inflammatory malignant fibrous histiocytoma (MFH). We describe an omental
The ovine brucellosis caused by Brucella ovis has tropism for reproductive tissues but until now the mechanism of bacterial persistence is not understood. Cytokine expression profiles were studied for 8 months in rams after being experimentally infected with the rough virulent strain of B. ovis
Various treatments have been used to change both the topography and chemistry of titanium surfaces, aiming to enhance tissue response and reduce healing times of endosseous implants. Most studies to date focused on bone healing around dental implants occurring later during the healing cascade.
Infection of sheep with Brucella ovis results in ovine brucellosis, a disease characterized by infertility in rams, abortion in ewes and increased perinatal mortality in lambs. During the course of the infection both the ovine immune response and host cell gene expression are modified. The objective
Recent advances in lipopolysaccharide (LPS) biology have led to its use in drug discovery pipelines, including vaccine and vaccine adjuvant discovery. Desirable characteristics for LPS vaccine candidates include both the ability to produce a specific antibody titer in patients and a minimal host
Wound healing is a complex and sequential biological process that involves multiple stages. Although various nanomaterials are applied to accelerate the wound healing process, only a single stage is promoted during the process, lacking hierarchical stimulation. Herein, hollow CeO2
Mycobacterium abscessus is a prevalent pathogenic mycobacterium in cystic fibrosis (CF) patients and one of the most highly drug resistant mycobacterial species to antimicrobial agents. It possesses the property to transition from a smooth (S) to a rough (R) morphotype, thereby influencing
