Electronic cigarette usage is becoming increasingly prevalent among school age children and young adults. A known bactericidal agent, propylene glycol, is often used as a carrier for nicotine, flavoring, and additional constituents of electronic cigarette juice. This study examined the relationship between propylene glycol and virulence gene expression in Streptococcus pyogenes, a respiratory tract pathogen commonly found in school-age individuals. A variety of virulence genes controlled by the three stand alone regulators mga, RofA, and Rgg/RopB were sampled in an effort to understand the pathway by which virulence is affected. The genes chosen encode C5a peptidase, fibronectin binding protein, hyaluronate lyase, NAD glycohydrolase, Streptococcal pyrogenic exotoxin A and B, streptodornase, streptokinase, Streptolysin O, and Streptolysin S. No significant change in gene expression was observed, but a novel method to test the effects of aerosols on cells was developed. This method can be used in the

This was a Phase II double-blinded randomized controlled evaluation of safety, immunogenicity and efficacy of MVA85A/AERAS-485 in BCG vaccinated infants without tuberculosis or HIV infection. Infants (126 to 182 days) received intradermal (ID) study vaccine (MVA85A/AERAS-485 or Candida skin test antigen control). All infants were to be followed for at least 15 months after the last infant was enrolled into the study. Given completion of enrollment in 21 months, the total duration of follow-up for each infant was scheduled to be at least 15 months and up to 36 months. Infants were to be followed for the entire duration of the study both for the development of tuberculosis and serious adverse events.. On enrollment to the study, eligible infants were assigned to a study group starting with Study Group 1 and were randomized in a 1:1 ratio within a study group to receive either MVA85A/AERAS-485 or Candida skin test antigen control. Infants were assigned to a safety cohort (Study Group 1), then into ...

1. A specific antibody, demonstrable by the technique of complement fixation, regularly appears, or increases in concentration, in the sera of human beings during an attack of mumps or during convalescence.. 2. Specific dermal hypersensitivity, demonstrable by the injection of heat-inactivated mumps virus, has been shown to develop in 6 human beings after recovery from mumps.. 3. Complement-fixing antibody and the hypersensitive state also emerge as a result of clinically inapparent infection with the virus of mumps.. 4. These two phenomena are apparently unrelated in respect to immunologic mechanisms.. 5. The data presented indicate that the complement fixation test should prove of value both in diagnosis and in the determination of immunity.. 6. The skin test for dermal hypersensitivity, on the other hand, becomes positive after recovery and therefore would appear to be useful only as an index of resistance.. ...

Serum specimens from 12 sick and 20 normal horses were examined for levels of different classes of immunoglobulin (Ig) by a single radial immunodiffusion. The level of IgA in the sera of sick horses was about 50% lower than in the sera of normal horses. By contrast, the level of serum IgG was higher in sick than in normal horses. Phytohemagglutinin (PHA) responsiveness of blood lymphocytes showed transient suppression during the stage of severe diarrhea. The regaining of PHA responsiveness of lymphocytes was observed simultaneously with the recovery process. However, the responsiveness of lymphocytes in recovered horses was still markedly lower than in normal horses. Allergic reactions in sick and normal horses were studied by observing dermal response to the injections of saline extracts from some of the horse feeds. A delayed hypersensitivity reaction to streptokinase-streptodornase and PHA was also studied. The allergic reactions to these extracts were not induced in either sick or normal ...

Contraindication:. Severe allergic reaction (e.g., anaphylaxis) to SPHERUSOL or any component of SPHERUSOL or history of allergic reaction to other coccidioidins. Warnings and Precautions:. Acute hypersensitivity reactions and anaphylaxis have occurred following the administration of other skin test antigens and may occur in individuals following the administration of SPHERUSOL.. Patients receiving beta-blocking drugs may be refractive to the usual dose of epinephrine in cases of hypersensitivity.. Any condition or agent that impairs or attenuates delayed-type hypersensitivity reactions, including infections and use of immunosuppressive drugs, can potentially cause a false negative reaction to SPHERUSOL. Adverse Reactions:. The most commonly reported local adverse reactions were itching and swelling (,75%) and pain (,15%) within 7 days of administration.. Drug Interactions:. Corticosteroids and immunosuppressive agents may suppress the response to the skin test.. Use in Specific ...

In June 2019, Par Pharmaceutical Companies, Inc. reported that Tuberculin, Purified Protein Derivative Aplisol® was expected to be in limited supply for 3-10 months. The CDC had not modified its recommendations for baseline TB testing due to the shortage. However, serial TB testing schedules were recommended to be modified in settings with a low likelihood of TB exposure. The shortage has since been resolved. Normal TB testing schedules may be resumed without the need to substitute Tubersol® or an interferon-gamma release assay (IGRA) blood test.. ...

Interferon gamma (IFNγ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes or tuberculin-sensitized mouse peritoneal lymphocytes challenged with PPD; the resulting supernatants were shown to inhibit growth of vesicular stomatitis virus. Those reports also contained the basic observation underlying the now widely employed interferon gamma release assay used to test for tuberculosis. In humans, the IFNγ protein is encoded by the IFNG gene. IFNγ, or type II interferon, is a cytokine that is critical for innate and adaptive immunity against viral, some bacterial and protozoal infections. IFNγ is an important activator of macrophages and inducer of Class II major histocompatibility complex (MHC) molecule ...

A glass-adherent human lymphoma cell line was found to produce an inhibitor of human in vitro lymphocyte blastogenic responses. The responses to mitogens, antigens, and allogeneic leukocytes were inhibited over 90%, as assayed by DNA synthesis or morphology. The effect was not associated with cytotoxicity and was reversible by washing the inhibited cells. The material was a nondialyzable, heat-stable protein. Its activity was not affected by its deoxyribonuclease and ribonuclease but was destroyed by Pronase. Most important, the inhibitor was species and tissue specific; it did not inhibit mouse lymphocytes or a variety of human tissue culture cell lines. The relationship of this material to regulation of lymphoid function and to the etiology and pathogenesis of cancer is discussed.. ...

HelloMy name is joao and Im 35 years old and healthy until now.I did a MRI (magnetic ressonance - 3 T) exam to my cervical, without contrast. After this exam, I went to bed and woke up in the middle of the night with a burning sensation all over my back. I looked in the mirror and my back and shoulders were full of wrinkles (depressions). It seemed like a dermographism (Pressure urticaria) but with a burning sensation associated (a kind of mechanical /dynamic allodynia). I asked my wife to take a picture: http://s3.amazonaws.com/medhelp_images/profiles/1070027_fs?1258314187 (I know this is the marks of the sheets, but I never ever had the skin so sensitive, and these are depressions, not erruptions. It takes only a few minutes for them to came out, and they burn) I also had a strange diarreha and my hair and genitals burn for some months. After 7 months this kind of allergy is still here. Every time I brush or make pressure to my body, there are these depressions on my skin and this burning ...

Sera from rabbits with early experimental syphilis were tested for their effect on in vitro lymphocyte transformation responses to related specific antigens (sonicated T. pallidum), unrelated specific antigens (sheep erythrocytes), and the T cell mitogen, concanavalin A. Results were compared with responses in preinfection sera and in sera from sham-infected rabbits. Titration experiments in which normal serum was used indicated that optimal lymphocyte responsiveness is obtained with a final serum concentration of 1%. Under these conditions, no differences in concanavalin A stimulation were observed in cultures with syphilitic sera. Responses to sonicated T. pallidum were inhibited, but only by 17 to 25% when compared with the response in preinfection sera. In cultures containing 10% serum, inhibition of lymphocyte proliferation to sonicated T. pallidum antigens was evident with sera from all syphilitic animals from day 10 (55% inhibition) through day 31 (80% inhibition) of infection. Responses ...

TY - JOUR. T1 - Interaction of acute phase reactive (APR) proteins with lectins. T2 - Its relationship to lymphocyte transformation. AU - Kudo, J.. AU - Okubo, H.. AU - Ikuta, T.. PY - 1982/1/1. Y1 - 1982/1/1. N2 - The effect of human α1-acid glycoprotein (α1 AGP), α1-antitrypsin (α1AT), and haptoglobin (Hp) on lectin-induced lymphocyte transformation was examined in vitro. Alpha1-AGP had a suppressive effect on phytohemagglutinin (PHA)-induced lymphocyte response, while it tended to accelerate concanavalin A (Con A) and pokeweed mitogen (PWM)-induced response. Alpha1-AT inhibited Con A-induced response but had no effect on PHA- and PWM-induced response. Hp (type 2-2) markedly inhibited all of the three lectin-induced responses. In order to examine the mechanism of the inhibition, the binding of the proteins to Con A and PHA was measured. Alpha1-AGP bound well to PHA and to some extent to Con A. Alpha1-AT bound to Con A but not to PHA. Hp had a strong affinity to both and inhibited the ...

TY - JOUR. T1 - Lysozyme stimulates lymphocyte proliferation in monocyte-depleted mixed lymphocyte cultures. AU - Rinehart, John J.. AU - Cerilli, James G.. AU - Jacob, Harry S.. AU - Osserman, Elliott F.. PY - 1982/3. Y1 - 1982/3. N2 - Human LZM was found to enhance 3H-thy uptake and lymphoblast transformation in monocyte-depleted MLC. The effect was maximal (up to sixfold increase) in low level (, 10,000 cpm) MLC. Maximal MLC enhancement was obtained with 250 μg/ml LZM; higher LZM concentrations appeared to be inhibitory. LZM enhancement of MLC could not be demonstrated in the presence of monocytes. LZM did not enhance lymphocyte responses to SKSD. Several observations support the possibility that LZM enhancement of MLC is due to LZM augmentation of stimulator cell antigenicity. LZM pretreatment of stimulator but not responder lymphocytes enhanced MLC. This enhancement was blocked by the LZM inhibitor tri-GlcNAc. LZM enhancement of MLC was maximum when the antigenic stimulus was minimized ...

In direct ELISA, the method of antigen mobilization is not specific. When serum is used as the source of target antigen, the proteins in the sample may stick to microtiter plate well and analyte in serum must compete with other proteins to bind with the well surface. This problem is eliminated by using secondary antibody specific for the test antigen in Indirect or sandwich ELISA. This is the key difference between direct and Indirect ELISA.. ...

The negative effects on adult height were greater for children who were younger when they enrolled in the trial, but these differences were not significant. The investigators found that the difference in growth velocity occurred primarily in prepubertal children who were 5-10 years of age at enrollment. The evaluation of cumulative dose also demonstrated a dose-response effect. Patients who received higher daily doses of inhaled steroids during the treatment had a correspondingly greater reduction in their average adult height. Other factors associated with a lower adult height were Hispanic ethnicity and female sex as well as skin test reactivity and vitamin D insufficiency. Of interest, cumulative prednisone exposure during the treatment phase was not associated with differences in adult height. The height difference ultimately displayed by the children resulted from differences in their growth velocity in the first 2 years after trial enrollment. Kelly and colleagues concluded that this ...

To the editor: Evaluation of the reported association between streptokinase therapy and the Guillain-Barré syndrome (1, 2) brings to light problems encountered by the Food and Drug Administration (FDA) in investigating serious, unexpected drug- or biologic-product-related events. Guillain-Barré syndrome has been reported to occur after viral and bacterial illnesses, immunization with swine influenza and other vaccines, surgical procedures, psychological disorders, and pregnancy (3). The syndrome is presumed to be the result of an abnormal immunologic process. Streptokinase, a bacterial protein, elicits a host immune response, and so, development of the syndrome after exposure to streptokinase may be biologically plausible.. One ...
