Anaemia among school children aged 6-11 years old in Gaza Strip, Palestine

The objective of the study was to determine the prevalence of anaemia among children aged 6-11 old years due to causes other than parasitic infections. The present study was a cross-sectional study that included 1446 school children of both sexes, distributed in three localities (Khanyounis, Gaza and Beit-lahia) of Gaza strip. The cut-off point for anaemia was determined according to the mean of haemoglobin for all studied school age children, which was (12 g/dl) in accordance to WHO criteria. The observed mean level of Hb was 12 g/dl; standard deviation was 0.915 while the normal value is ranged between 8.9-15.2. Anaemia was found slightly higher in girls (36.3%) than boys (34%). The results showed that anaemia constitute a health problem in Gaza with a prevalence of 35.3%. No variation in the prevalence of anaemia among the three studies areas. It is concluded that anaemia still constitutes a health problem among schoolchildren with a present prevalence among school–age children of 35.3%. It is expected that the prevalence of anaemia may be higher than that reported by this study due to Israeli siege to Gaza Strip

Bis(oxonium) tetra­kis(o-toluidinium) cyclo­hexa­phosphate

In the title compound, 4C7H10N+·2H3O+·P6O18 6−, the complete cyclo­hexa­phosphate anion is generated by crystallographic inversion symmetry. In the crystal, the H3O+ ions and the [P6O18]6− anions are linked by O—H⋯O hydrogen bonds, generating infinite layers lying parallel to the ab plane at z = 1/2. These layers are inter­connected by the organic cations, which establish N—H⋯O hydrogen bonds with the [P6O18]6− anions

Regenerative memory in time-delayed neuromorphic photonic resonators

We investigate a photonic regenerative memory based upon a neuromorphic oscillator with a delayed self-feedback (autaptic) connection. We disclose the existence of a unique temporal response characteristic of localized structures enabling an ideal support for bits in an optical buffer memory for storage and reshaping of data information. We link our experimental implementation, based upon a nanoscale nonlinear resonant tunneling diode driving a laser, to the paradigm of neuronal activity, the FitzHugh-Nagumo model with delayed feedback. This proof-of-concept photonic regenerative memory might constitute a building block for a new class of neuron-inspired photonic memories that can handle high bit-rate optical signals

Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory

We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional information on any observed anisotropies. No deviation from isotropy is observed on any angular scale in the energy range between 4 and 8 EeV. Above 8 EeV, an indication for a dipole moment is captured; while no other deviation from isotropy is observed for moments beyond the dipole one. The corresponding $p$-values obtained after accounting for searches blindly performed at several angular scales, are $1.3 \times 10^{-5}$ in the case of the angular power spectrum, and $2.5 \times 10^{-3}$ in the case of the needlet analysis. While these results are consistent with previous reports making use of the same data set, they provide extensions of the previous works through the thorough scans of the angular scales.Comment: Published version.

Serum Islet Cell Autoantibodies During Interferon α Treatment in Patients With HCV-Genotype 4 Chronic Hepatitis

Chronic hepatitis C virus (HCV) infection is a leading cause of end-stage liver disease worldwide and HCV genotype 4 (HCV4) is predominant in African and Middle Eastern countries. It is well established that interferon-α (IFNa) treatment for HCV may trigger serum autoantibodies against pancreatic islet cells (ICA) in a subgroup of patients. Available data on the incidence of ICA during IFNa therapy for chronic HCV4 infection are not conclusive. We investigated the appearance of ICA in 40 naïve Egyptian patients (38 males, 32 ± 6 years) with histologically defined chronic HCV4 infection undergoing IFNa treatment at a dose of 9-million U/week for 24 weeks. Serum samples were collected at baseline and following IFNa therapy and ICA were detected using indirect immunofluorescence. Baseline evaluation indicated that 2/40 (5%) patients had detectable serum ICA. After the completion of the treatment scheme, 12/38 (32%) previously ICA negative patients became ICA positive; however, no patient developed impaired glucose tolerance (IGT) or diabetes during follow-up. In conclusion, we submit that IFNa treatment for chronic hepatitis C (CHC) may induce serum ICA in one-third of Egyptian patients with HCV4. These autoantibodies, however, do not lead to alterations in glucose metabolism
