The invention provides methods, kits and reagents for diagnosing fibromyalgia (FM) in an individual by determining whether the levels of one or more cytokines in the individual are altered, as compared to control levels. The altered level(s) or patterns of expression of the cytokines measured in the affected individual compared to the level from the control is predictive/indicative of FM in the individual.

The subject invention pertains to systems and methods diagnosing, monitoring and treating women for successful embryo implantation and establishment of pregnancy using peripheral blood cytokine profiling and administration of immune-modulators to establish an implantation-promoting microenvironment in the uterus.

An encryption device for performing virtual and real operations and a method of operating the encryption device. The method includes performing a virtual operation; when a real operation request signal is received, determining whether the virtual operation being performed is completed; and in response to the virtual operation being completed, performing a real operation in response to the real operation request signal.

An anti-IL5 nanoantibody, and a coding sequence for coding the anti-IL5 nanoantibody, a corresponding expression vector, a host cell capable of expressing the anti-IL5 nanoantibody, and a method for producing the anti-IL5 nanoantibody are provided. The nanoantibody can specifically recognize IL5 from humans and cynomolgus monkeys, does not recognize IL5 from mice, and has a good binding activity. The nanoantibody has a good IL5/IL5R blocking activity. The blocking activity is obviously superior to that of a control antibody Nucala. The nanoantibody can effectively inhibit the proliferation of TF-1 cells induced by IL5, and the inhibition activity thereof is superior to that of the control antibody Nucala. The expression yield of the nanoantibody in Pichia pastoris can reach 13 g/L, and the purity of target protein expressed in the supernatant is high.

EphA2 T-cell epitope are provided herein. The epitopes include peptides corresponding to specific fragments of human EphA2 protein containing one or more T-cell epitopes, and conservative derivatives thereof. The EphA2 T-cell epitopes are useful in an assay, such as an ELISPOT assay, that may be used to determine and/or quantify a patient's immune responsiveness to EphA2. The epitopes also are useful in methods of modulating a patient's immune reactivity to EphA2, which has substantial utility as a treatment for cancers that overexpress EphA2, such as renal cell carcinoma (RCC). The EphA2 epitopes also can be used to vaccinate a patient against EphA2, by in vivo or ex vivo methods.

Provided herein is a method for measuring the levels of chronic inflammaging (SCI) of a subject. In some embodiments, the method may comprise measuring the amount of two or more of the proteins CXCL9, TRAIL, IFNG, EOTAXIN and GROA in a sample (e.g., blood serum) from the subject calculating a score based on the weighted amounts of each of those proteins.

The present invention relates to a method of diagnosing over active bladder disorder (OAB), the method comprising: measuring the concentrations of adenosine triphosphate (ATP), acetylcholine (ACh), nitrite, monocyte chemoattractant protein 1 (MCP-1) and interleukin 5 (IL-5) in a sample obtained from a subject; normalising the concentrations to the concentration of creatinine (Cr) in the sample; range standardising the normalised concentrations and subject's age to the following values: Age to 120 years old; ATP/Cr to 0.000001 mole/mgxdl.sup.1; ACh/Cr to 0.1 mole/mgxdl.sup.1; Nitrite to 200 nM/mgxdl.sup.1; MCP-1/Cr to 100 pgxml.sup.1/mgxdl.sup.1; IL-5/Cr 100 pgxml-mgxdl.sup.1; applying the normalised and range standardised concentrations to the following formula: Logit (p)=1.7381.4044.9852.914subject's age+3315.9595435.254[ATP]/[Cr]+(25204.19420268.337)[ACh]/[Cr]+26.79932.967[nitrite]/[Cr]+6.75525.132 [MCP-1]/[Cr]+(61.838148.740) [IL-5]/[Cr] and calculating Logit; wherein a Logit value above a predetermined threshold indicates that the subject has OAB. Methods for monitoring the progression of OAB using the method, kits for use in the method and computer systems and programs configured to execute the method are also provided.
