Hirsutism will be not Considered as Sign of Progressive Disease after Autologous Transplant in POEMS Syndrome

POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) syndrome is a rare multisystem disease characterized by plasma cell dyscrasia and overproduction of vascular endothelial growth factor (VEGF). Skin changes are usually multiple cutaneous angiomas, leukonychia, necrotizing vasculitis, cutaneous thickening of sclerodermiform type and hypertrichosis. VEGF is assumed to be useful in monitoring disease activity, because VEGF levels usually decrease after treatment. We described the case of a young woman with POEMS syndrome characterized by hirsutism and hypertrichosis who underwent autologous bone marrow transplantation . Evolutionwas hallmarked by an improvment of radiological signs and biological markers specially VEGF, while hirsutism didn’t regress.

Detection of the host-specific Bacterioides and Bifidobacteriumsaeculare markers in surface water in Hanam, Vietnam with real-time PCR

The microbiological quality of coastal or river waters can be affected by faecal pollution from human or animal sources. Contamination of fresh produce with pathogenic bacteria can be attributed directly or indirectly to the raw wastewater (domestic, industrial effluents, human and animal excrement). This includes water sources that are routinely used for crop irrigation and produce washing. An efficient MST (Microbial Source Tracking) toolbox consisting of several host-specific markers would, therefore, be valuable for identifying the origin of the faecal pollution in the environment and thus for effective resource management and remediation. As a result, the need for expanding from traditional techniques to molecular methods has been highly recommended.

Mechanisms of Resistance to Kinase Inhibitors and Strategies to Prevent the Development of Drug Resistance

Targeting mutant proteins and associated signaling pathways of driver oncogenes by small molecule kinase inhibitors (KIs) are a promising strategy of cancer therapy. However, despite the initial success of treatment, KIs often become ineffective as intrinsic and acquired resistance. This article reviews the English-language literature to explore the underlying mechanisms of drug resistance and to present a challenge for developing drugs to overcome resistance. Mechanisms of acquired resistance include 1) the selection of pre-existing subclones with other mutations, 2) the emergence of secondary mutations in the target kinase domain, 3) upregulation of kinases both within the same kinase family and their related kinase families, as well as activation of alternative bypass pathways, 4) epithelial-mesenchymal transition, 5) overexpression of pro-survival Bcl-2 family proteins and 6) drug efflux mechanisms. Currently available methods are to obtain tumor biopsy samples at recurrence or progression if the tumor lesion is accessible to a biopsy and to use the second- and third-generation KIs based on the individual need of each patient. Furthermore, recent computational challenges provide design principles to prevent the development of drug resistance. In conclusion, we provide an overview of the postulated resistance mechanisms and highlight the future direction of computational structure-based design of new potent KIs.

Giemsa Staining and Antibody Characterization of Colpodella sp. (Apicomplexa)

Colpodella species are free-living alveolates that possess an apical complex used for attaching to eukaryotic prey protists for ingestion of the cytoplasmic contents of the prey. Colpodella sp. are the closest relatives of the Apicomplexa, a phylum that includes the important human pathogens Plasmodium falciparum, Toxoplasma gondii and Cryptosporidium parvum. In this study, we investigated morphological characteristics of Colpodella (ATCC 50594) in a diprotist culture containing Bodo caudatus as prey in order to identify features differentiating both protists. The level of apical complex protein conservation among free living alveolate relatives of apicomplexans and intracellular apicomplexan pathogens is unknown. Antibodies against proteins of the apical complex in Colpodella sp. are currently unavailable. We performed staining and immunological characterization of Colpodella in a diprotist culture containing B. caudatus to aid routine differentiation of predator and prey in culture. Staining revealed distinguishing morphological features of both protists. The kinetoplast in B.caudatus was identified using Giemsa staining and was used to differentiate B. caudatus from Colpodella sp. trophozoites.

United States Air Force Academy: Identifying Areas at Risk for the Persistence of Plague using the Bioagent Transport and Environmental Modeling System (BioTEMS)

Introduction: Yersinia pestis, the etiologic agent of plague, has caused major pandemics in human history and continues to be both a natural and bioterrorist threat to human populations. Plague exists in nature in either an epidemic or enzootic state. Geographic models of the epidemic state have primarily been developed using flea and reservoir species, however little is known of the enzootic state and potential cryptic reservoir species and few endemic models have been produced.

Scardovia Wiggsiae and the Other Microorganisms in Severe Early Childhood Caries

Severe early childhood caries (S-ECC) is an aggressive form of tooth caries in preschool children. New different bacteria were defined as associated with S-ECC. The aim of this study was to analysis the role of Scardovia wiggsiae and the other cariogenic microorganisms in S-ECC in Turkish children. Two same-sized groups of children were enrolled in the study: the first group consisted of 40 children with S-ECC (mean-age:52.93±11.5months), and the second group consisted of 40 caries-free children (mean-age:49.43±12.47months). The numbers of mutans streptococci, lactobacilli and yeasts were examined by culturing techniques, while the presences of S. wiggsiae, Streptococcus mutans, Streptococcus sobrinus, Actinomyces gerencseriae, Veillonella parvula, Fusobacterium nucleatum were examined by using 16S rRNA-based PCR technique in plaque samples. The prevalence of S. wiggsiae, S. mutans, A. gerencseriae, V. parvula and the numbers of mutans streptococci, lactobacilli, yeasts were found significantly high (P<0.05) in SECC. Also, the presence of S. wiggsiae with either S. mutans, A. gerencseriae, V. parvula or F. nucleatum were associated (P<0.01) with S-ECC. Understanding the effects of bacteria on initiation and progression of S-ECC will also help to improve protective and preventive treatments.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
