It is used in scientific research, surveillance cameras industry and robotics technology as well. The human interaction with the objects creates a complex stance. Multiple artefacts such as clutter, occlusions, and backdrop diversity contribute to the complexity of this technology. Wi-Fi signals with the usage of their features could help solve some of these issues, with the help of other wearable sensors, such as: RGB-D camera, IR sensor (thermal camera), inertial sensor etc. This paper reviews various approaches for Wi-Fi human motion recognition systems, their analytical methodologies, challenges and proposed techniques along with the aspects to this paper: (a) applications; (b) single and multi-modality sensing; (c) Wi-Fi-based techniques; d) challenges and future works. More research related to Wi-Fi human related activity recognition can be encouraged and improved.

The European Expert Panel has advocated universal screening as a preferable approach of hypercholesterolemia screening as a part of the primary preventive effort. Objective: To assess the relation between dyslipidemia and its risk factors; age and body mass index. Patients and Methods: A cross-sectional study that included 357 of children who visited the Pediatrics General Outpatient Clinic at Zagazig University Hospitals. All subjects were subjected to full history taking, general examination, anthropometric measurements, blood pressure, and laboratory investigations including: non-fasting and fasting lipid profiles. Results: Non-fasting total cholesterol (TC) of ≥ 200 was (14.3%) and < 200 was (85.7%). Non-fasting (LDL) of ≥ 130 was (16.8%) and <130 was (83.2%). HDL category of < 40 was (61.3%) and ≥ 40 was (38.7%). There was no statistically significant difference between age, sex and lipid profiles. There was statistically significant positive correlation between non-fasting triglycerides (TG) and non-fasting HDL and non-fasting non-HDL-C. Conclusion: Obesity was associated with the prevalence of at least one abnormal lipid level. This highlights the importance of paying greater attention to the prevention of cardiovascular disease and obesity in children from an early age.

The conjugation of chitosan with green synthesized silver nanoparticles (SNPs) to form a nanocomposite film will greatly affect the structural properties of chitosan film. This study aimed to evaluate the physical properties of chitosan films doped with different concentrations of SNPs (100-400 g). X-ray diffraction (XRD) and dynamic mechanical analysis (DMA) were measured for pure chitosan and chitosan films doped with SNPs (100-400 g). XRD pattern for chitosan film doped with the highest concentration of SNPs (400 g) showed a decrease in the crystallinity of the chitosan matrix compared with the other doped films. Also, DMA results showed that the storage modulus of the nanocomposite films is dependent on the concentration of SNPs. Accordingly, chitosan film doped with high concentration of SNPs (400 g) affected the structure and viscoelastic behaviour of chitosan. Thus, the integration of green synthesized silver nanoparticles using aloe vera extract with chitosan films identifies promising candidate in biomedical applications.

The applications of silver nanoparticles in the biological environment are always obstructed by oxidation that causes aggregation of nanoparticles which lowers its antibacterial activity. In this research, silver nanoparticles were coated on the surface of mesoporous silica forming mesoporous silver nanoshells (Ag@ MSNs). The prepared nanoparticles were characterized by their zeta potential, particle size, UV absorption spectroscopy, and transmission electron microscopy. Additionally, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) were also performed. The antimicrobial activity of the prepared Ag@MSNs was evaluated against gram-positive and gram-negative pathogens. The results showed that Ag@MSNs are monodispersed with an average size distribution 272 ± 61 nm. Ag@MSNs are highly stable with zeta potential value of 43.3 ± 6.5 mV and an absorption peak at 235 nm. Small-angle X-ray diffraction demonstrated a narrow and strong peak at 2ϴ = 1.71 ο indicating that the Ag@MSNs have an ordered porous structure. Surface coating of mesoporous silica nanoparticles with silver shells increased the contact surface area with the bacterial membrane. Thus, Ag@MSNs significantly inhibited the growth of Staphylococcus aureus and E-coli. In conclusion the present study gives new insights into the synthesis of antimicrobial nano-formulation that can offer a variety of uses in industry and biomedical applications.

Venous thrombosis has an overall yearly incidence of less than 1 in 1000 [2]. A middle-aged female patient without relevant medical history was admitted with syncope and pancytopenia to the critical care unit of Cairo University hospitals. Viral profile and renal and hepatic functions were normal, as well as bone marrow aspirate. Abdominal ultrasound followed by computed tomography of the abdomen showed moderate splenomegaly with no focal splenic lesions for clinical laboratory correlation and portal hypertension with portal vein cavernoma (mostly an organized old thrombosis during pregnancy) for color Doppler evaluation, which confirmed the diagnosis. Thrombophilia screening showed rare multiple thrombophilic genetic defects.

However, other T-helper effector cells; T-helper17 and T-helper2; play a role, particularly in the context of disease type. Aims: We aimed to evaluate serum levels of interleukin (IL)-17 (T-helper17 cytokine) and IL-4 (T-helper2 cytokine) in untreated patients with different types of leprosy, compared to controls. Methods: Using enzyme-linked immunosorbent assay, serum IL-17 and IL-4 levels were estimated in 43 leprotic patients and 43 controls. Patients were divided into six groups; tuberculoid, borderline cases, lepromatous, erythema nodosum leprosum (ENL), type 1 reactional leprosy, and pure neural leprosy. Patients were also categorized according to bacillary load and the presence or absence of reactions. Results: Serum IL-17 was signifi cantly lower in cases (4-61.5 pg/mL; median 19), compared to controls (26-55 pg/mL; median 36) (P < 0.001), and was signifi cantly lower in each type of leprosy compared to controls, with the lowest level in lepromatous leprosy (4-61.5 pg/mL; median 12.5). Signifi cantly elevated serum IL-4 was found in patients (1.31-122.4 pg/mL; median 2.31) compared to controls (1.45-5.72 pg/mL; median 2.02) (P = 0.008), with the highest level among lepromatous leprosy patients (2-87.2 pg/mL; median 28.9), and the lowest in type 1 reactional leprosy (1.4-2.5 pg/mL; median 1.87) (P = 0.006). Conclusion: Defective secretion of IL-17 is related to disease acquisition as well as progression toward lepromatous pole in leprosy patients. The overproduction of IL-4 in patients with lepromatous leprosy may infer their liability to develop ENL. Nevertheless, the small number of the studied population is a limitation.
