Leap Motion Controller (LMC) is a gesture sensor consists of three infrared light emitters and two infrared stereo cameras as tracking sensors. LMC translates hand movements into graphical data that are used in a variety of applications such as virtual/augmented reality and object movements control. In this work, we intend to control the movements of a prosthetic hand via (LMC) in which fingers are flexed or extended in response to hand movements. This will be carried out by passing in the data from the Leap Motion to a processing unit that processes the raw data by an open-source package (Processing i3) in order to control five servo motors using a micro-controller board. In addition, haptic setup is proposed using force sensors (FSR) and vibro-motors in which the speed of these motors is proportional to the amount of the grasp force exerted by the prosthetic hand. Investigation for optimal placement of the FSRs on a prosthetic hand to obtain convenient haptic feedback has been carried out. The results show the effect of object shape and weight on the obtained response of the FSR and how they influence the locations of the sensors.

Background: Peripheral blood lymphocytes (PBL)of Rheumatoid arthritis (RA)patients have a property of phenotypic and functional activation. Glutathione S- transferase pi (GSTπ) has been implicated in playing an important role in the initiation and progression of cellular activation.Objectives: To determine the percentage of cellular expression of GSTπ in the lymphocytes of RA patients in comparison with controls and to explore the relation between its cellular expression and disease activity pattern.Patients and Methods: This prospective study included46 RA patients and 17 healthy controls. Blood samples were taken and from all subjects PBL were isolated and then smeared on slides. The cellular reactivity for GSTπ was determined by immunocytochemistry technique.Results: This study found lower expression of GSTπ in the RA patients with a statistical significant difference with control group, while no statistical difference was found in RA with high and minimum disease activity groups. No correlation was observed between GSTπ with Disease Activity Score (DAS).Conclusion: Although the decrease in the expression of GSTπ in PBLs was pronounced in RA patients, however it doesn’t correlate with disease activity state.

The current research deals with molecular systematics study of the genus Eryngium (Apiaceae) in Iraq. The study included molecular characteristics traits of chloroplast matK & trnL-F gene that have reliable value in separate and determinate the genus from others genera in Apiaceae family. The result of molecular study reaches to investigated the phylogenetic relation of the species belongs to Erymgium using five in-group species E. campestre L., E. creticum Lam., E. billardieri Del., E. glomerutum Lam. and E. thyrosoideum Boiss and one out-group pycnocycla aucheriana were used as related species. Based on trnL-F & matK intergeneric chloroplast gene.
