A method for detection of active form of analytes in a sample and/or for determination of ability of tested substances to bind to the active site of these analytes has the following steps: a) analyte or group of analytes from the sample is immobilized on the surface of a solid carrier; b) analyte or group of analytes is incubated with a detection probe; c) then the solid carrier is washed to remove unbound detection probe; and subsequently, the amount of bound detection probe is determined.

Presented herein are compositions, methods, and kits for determining whether a pulmonary nodule is cancer and/or is not cancer.

Three recombinant E. coli strains produce the enzymes CPD-photolyase, 6,4-bifunctional photolyase and 6,4-photolyase, from bacterial Antarctic isolates of the genus Hymenobacter the first one and Sphingomonas the others. It is also disclosed a process of production and purification of the recombinant enzymes with high performance, high degree of purity and high catalytic repair activity, having applications in, but it is not limited to, cosmetics and pharmaceutical industry. A fast, cheap and qualitative method is provided for the determination of the CPD photolyase activity.

Compositions and methods of treating an inflammatory disease in a subject are provided. Accordingly there is provided a method comprising administering to the subject a therapeutically effective amount of an agent which selectively inhibits activity and/or expression of iron regulatory protein (IRP) 1 and not IRP2, thereby treating the inflammatory disease in the subject. Also provided is a pharmaceutical composition comprising, as an active ingredient, an agent which selectively inhibits activity and/or expression of IRP1 and not IRP2, and a pharmaceutically acceptable carrier or excipient. Also provided are methods of identifying an agent that selectively modulates an activity of an IRP member of an IRP family of polypeptides and not of an additional IRP member of said IRP family of polypeptides.

The present disclosure relates to the use of an agent that inhibits the activity of or decreases the levels of an L-dopa decarboxylase conjointly with levodopa (L-dopa) in the treatment of a condition.

The present disclosure relates to compositions and methods for identifying a subject at risk for traumatic brain injury. In particular, the instant disclosure is directed to identification of the levels of the proteins MMP-9 (Matrix Metallopeptidase 9), NSE (Neuron Specific Enolase) and VCAM-1 (Vascular Cell Adhesion Molecule 1) in a subject sample, and correlation of these protein levels with the presence of intracranial injury. In certain embodiments, subject age, gender and hemoglobin level are also correlated with the presence of intracranial injury.

The present invention provides methods for identifying biomarker proteins that exhibit differential expression in subjects with a first lung condition versus healthy subjects or subjects with a second lung condition. The present invention also provides compositions comprising these biomarker proteins and methods of using these biomarker proteins or panels thereof to diagnose, classify, and monitor various lung conditions. The methods and compositions provided herein may be used to diagnose or classify a subject as having lung cancer or a non-cancerous condition, and to distinguish between different types of cancer (e.g., malignant versus benign, SCLC versus NSCLC).

A method of selecting a treatment for a subject having cancer is disclosed. The method comprises: (a) determining a level of catalytic activity of at least one DNA repair enzyme in a biological sample of the subject; and (b) selecting an immune checkpoint regulator as a treatment for a subject having a statistically significant different level of catalytic activity of said DNA repair enzyme as compared to the catalytic activity of said DNA repair enzyme in a biological sample of a healthy subject.

The disclosure provides peptides and pharmaceutical compositions thereof. Such peptides can be useful, for example, in treating various human diseases such as immunological diseases. In some embodiments, the peptides are useful as immunotherapeutics for modulating regulatory and effector molecules of the mammalian immune system.

The presently disclosed invention relates to a method of diagnosing Multiple Sclerosis (MS) in a patient comprising obtaining a sample from the patient, determining a level of one or more H2S generating enzymes in the sample from the patient, and diagnosing the patient with MS when the level of the one or more H2S generating enzymes is one of at least 15% higher or lower than a control level for the one or more H2S generating enzymes, and at least 10% higher or lower than a control level for the one or more H2S generating enzymes.
