RESUMO
INTRODUCTION: Chronic kidney disease (CKD) stage 5 is a common pathology, the increase in its incidence and prevalence has been noted worldwide. In Algeria, few studies have been done on the epidemiology of chronic kidney disease, the real extent of its incidence in southern Algeria remains unknown. AIM: To determine the incidence in 2017 of chronic kidney disease stage 5 treated by renal replacement in southeastern Algeria. METHOD: During our multicenter, prospective longitudinal regional study, from January 1, 2017 to December 31, 2017, all resident incident cases of CKD stage 5 treated in the region by renal replacement were recruited. RESULTS: The crude incidence of stage 5 CKD treated in 2017 in southeastern Algeria was 75 pmh. The age-standardized incidence rate was 100 pmh, with a male predominance, a M/F sex ratio of 1.59. The average age of incident cases was 48.50 ± 19.12 years. The incidence varies by age group and by wilaya. Diabetes (26.7%) and hypertensive nephropathy (22.6%) represent almost half of the cases and primary glomerulonephritis represents 5.9%. CONCLUSION: CKD stage 5 treated, due to its high incidence in Algeria, with large geographical variations, represents a major public health challenge. It mainly affects young people. Diabetes and high blood pressure represent the two main causes, encouraging prevention efforts to be focused on hypertensives and diabetics in high-risk wilayas.

Phosphate-based NASICON materials are an excellent candidate for both electrode and solid electrolyte materials in sodium-ion batteries (SIBs). The development of new NASICON materials with higher ionic and electronic conductivities based on low cost and abundant elements is necessary for advancement of SIBs. In this study, we report the structure, morphology and conductivity of the earth-abundant Mn/Fe-based NASICON phosphate Na4MnFe(PO4)3. Pure phase powders were synthesized by solution-assisted solid-state reaction, sol-gel and Pechini methods. From refined X-ray diffraction data, the prepared phosphate was found to crystallize in trigonal symmetry with space group R3Ìc. The effect of synthesis method on microstructure and conductivity was investigated using scanning electron microscopy (SEM), atomic force microscopy (AFM) and impedance measurements. Smaller particle size and regular distribution of the powder was designed using a Pechini route. Impedance measurement showed a notable enhancement in conductivity, from 0.543 × 10-7 to 1.52 × 10-7 S cm-1 at 30 °C, when the powder synthesis method was altered from a solution-assisted solid-state reaction to the Pechini route, highlighting the remarkable effect of the synthesis method on conductivity.
RESUMO
Ferroelectric, phase-change, and magnetic materials are considered promising candidates for advanced memory devices. Under the development dilemma of traditional silicon-based memory devices, ferroelectric materials stand out due to their unique polarization properties and diverse manufacturing techniques. On the occasion of the 100th anniversary of the birth of ferroelectricity, scandium-doped aluminum nitride, which is a different wurtzite structure, was reported to be ferroelectric with a larger coercive, remanent polarization, curie temperature, and a more stable ferroelectric phase. The inherent advantages have attracted widespread attention, promising better performance when used as data storage materials and better meeting the needs of the development of the information age. In this paper, we start from the characteristics and development history of ferroelectric materials, mainly focusing on the characteristics, preparation, and applications in memory devices of ferroelectric wurtzite AlScN. It compares and analyzes the unique advantages of AlScN-based memory devices, aiming to lay a theoretical foundation for the development of advanced memory devices in the future.
RESUMO
We report the synthesis of two novel halogenated nitro-arylhimachalene derivatives: 2-bromo-3,5,5,9-tetramethyl-1-nitro-6,7,8,9-tetrahydro-5H-benzo[7]annulene (bromo-nitro-arylhimachalene) and 2-chloro-3,5,5,9-tetramethyl-1,4-dinitro-6,7,8,9-tetrahydro-5H-benzo[7]annulene (chloro-dinitro-arylhimachalene). These compounds were derived from arylhimachalene, an important sesquiterpene component of Atlas cedar essential oil, via a two-step halogenation and nitration process. Characterization was performed using 1H and 13C NMR spectrometry, complemented by X-ray structural analysis. Quantum chemical calculations employing density functional theory (DFT) with the Becke3-Lee-Yang-parr (B3LYP) functional and a 6-31++G(d,p) basis set were conducted. The optimized geometries of the synthesized compounds were consistent with X-ray structure data. Frontier molecular orbitals and molecular electrostatic potential (MEP) profiles were identified and discussed. DFT reactivity indices provided insights into the compounds' behaviors. Moreover, Hirshfeld surface and 2D fingerprint analyses revealed significant intermolecular interactions within the crystal structures, predominantly H-H and H-O contacts. Molecular docking studies demonstrate strong binding affinities of the synthesized compounds to the active site of protein 7B2W, suggesting potential therapeutic applications against various isolated smooth muscles and neurotransmitters.
RESUMO
New calcium borovanadate glass containing manganese ions within the system x Mn2O3-(30-x) V2O5-50 B2O3-20 CaO has been elaborated* in this work using melt quench process. The primary objective of this research is to examine the influence of introducing Mn2O3 upon the various properties of the elaborated glass specimens including physical, thermal, structural, optical and magnetic properties. X-ray diffraction indicated that the samples prepared were amorphous. The variation in density and molar volume revealed that the structure of the glass matrix cross-links and becomes more compact with increasing Mn2O3 content, which is confirmed when the glass transition temperature is increased. Furthermore, in order to check the group constitution of our glasses, a structural study was carried out using infrared (FTIR) and Raman spectroscopy. The optical characteristics of our vitreous materials were analyzed by UV solid, and the results of the band gap energy and refractive index values revealed an enhancement of non-bridging oxygen atoms (NBOs) with rising Mn2O3 concentration, also suggests that manganese acts as a structure modifier. The low Urbach energy values are an indication that the structure of our glasses is stable and uniform. The magnetic investigation highlighted the presence of the predominant antiferromagnetic order in the glass samples studied, which becomes stronger with the incorporation of more manganese ions into the structure.
RESUMO
In this study, a chemical precipitation approach was adopted to produce a photocatalyst based on bismuth tungstate Bi2WO6 for enhanced and environmentally friendly organic pollutant degradation. Various tools such as X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), optical spectroscopy and X-ray photoelectron spectroscopy, were employed to assess the structural and morphological properties. Hence, the XRD profiles showed a well crystallized Bi2WO6 orthorhombic phase. The photocatalytic performance of the resulting photocatalyst was assessed by the decomposition of Rhodamine B (RhB) and methyl orange (MO) with a decomposition efficiency of 97 and 92%, along with the highest chemical oxygen demand of 82 and 79% during 120 min of illumination, respectively. The principal novelty of the present work is to focus on the changes in the crystalline structure, the morphology, and the optical and the photoelectrochemical characteristics of the Bi2WO6, by tuning the annealing temperature of the designed photocatalyst. Such physicochemical property changes in the as-prepared photocatalyst will affect in turn its photocatalytic activity toward the organic pollutant decomposition. The photocatalytic mechanism was elaborated based on electrochemical impedance spectroscopy, photocurrent analysis, photoluminescence spectroscopy, and radical trapping measurements. The overall data indicate that the superoxide O2â¢- and holes h+ are the principal species responsible for the pollutant photodegradation.
RESUMO
A novel phosphate containing barium, cobalt, and iron was synthesized in single-crystal and polycrystalline forms. Single crystal-based X-ray measurements revealed that it crystallizes in the monoclinic system with the P21/c space group. The structure is made up of linkages between FeO6 octahedra, CoO4 square planar units, CoO5 square pyramidal units, and PO4 tetrahedra through edges and/or vertices. The interconnection of these polyhedra leads to a three-dimensional framework with tunnels along the a-axis where the Ba2+ cations are located. The polycrystalline form was prepared via the sol-gel method and its XRD pattern was refined by the Le Bail method. Morphological and elemental mapping analyses of this phosphate were performed by scanning electron microscopy. In addition, infrared and Raman spectroscopy provided more insights into chemical bonding. The magnetic behavior was antiferromagnetic below TN â¼ 20 K. Optical measurements revealed a direct bandgap with an energy Eg of 2.83 eV.

Our objective is to describe the epidemiology of stage V chronic kidney disease treated in south-eastern Algeria. Patients and methods: In our regional, multicenter, prospective descriptive study, all patients with stage V chronic kidney disease, residing and treated in south-eastern Algeria between September 1, 2016, and December 31, 2017, were included and followed up until December 31, 2018. Results: Stage V chronic kidney disease is a frequent pathology in the region: 1934 patients were included. It mainly affects young people: the average age of patients was 50.17 ± 16.98 years, with a male predominance of 59.10%. High blood pressure and diabetes are the two main causes. The start of dialysis on a temporary catheter represents 81.5% of cases, the initial management requires emergency dialysis in 91.2% of cases. In total, 97.1% of chronic hemodialysis patients use an arteriove-nous fistula as a permanent vascular access. Conclusion: Our study population is younger than that of developed countries and has fewer comorbidities and disabilities but lower survival and high mortality. The developing national chronic kidney disease stage V registry is becoming an absolute necessity. It will allow to have a better knowledge of its epidemiology and the needs of its care in each region. It can contribute to improving the prevention and management of this disease.

The orthophosphate BaNi2Fe(PO4)3 has been synthesized by a solid-state reaction route and characterized by single-crystal X-ray diffraction and energy-dispersive X-ray spectroscopy. The crystal structure comprises (100) sheets made up of [Ni2O10] dimers that are linked to two PO4 tetra-hedra via common edges and vertices and of linear infinite [010] chains of corner-sharing [FeO6] octa-hedra and [PO4] tetra-hedra. The linkage of the sheets and chains into a framework is accomplished through common vertices of PO4 tetra-hedra and [FeO6] octa-hedra. The framework is perforated by channels in which positionally disordered Ba2+ cations are located.
RESUMO
Single crystals of tricadmium orthophosphate, Cd3(PO4)2, have been synthesized successfully by the hydro-thermal route, while its powder form was obtained by a solid-solid process. The corresponding crystal structure was determined using X-ray diffraction data in the monoclinic space group P21/n. The crystal structure consists of Cd2O8 or Cd2O10 dimers linked together by PO4 tetra-hedra through sharing vertices or edges. Scanning electron microscopy (SEM) was used to investigate the morphology and to confirm the chemical composition of the synthesized powder. Infrared analysis corroborates the presence of isolated phosphate tetra-hedrons in the structure. UV-Visible studies showed an absorbance peak at 289â nm and a band gap energy of 3.85â eV, as determined by the Kubelka-Munk model.
RESUMO
The discovery and development of new potent antimicrobial and antioxidant agents is an essential lever to protect living beings against pathogenic microorganisms and free radicals. In this regard, new functionalized pyrazoles have been synthesized using a simple and accessible approach. The synthesized aminobenzoylpyrazoles 3a-h and pyrazole-sulfonamides 4a-g were obtained in good yields and were evaluated in vitro for their antimicrobial and antioxidant activities. The structures of the synthesized compounds were determined using IR, NMR, and mass spectrometry. The structure of the compound 4b was further confirmed by single crystal X-ray diffraction. The results of the in vitro screening show that the synthesized pyrazoles 3 and 4 exhibit a promising antimicrobial and antioxidant activities. Among the tested compounds, pyrazoles 3a, 3f, 4e, 4f, and 4g have exhibited remarkable antimicrobial activity against some microorganisms. In addition, compounds 3a, 3c, 3e, 4a, 4d, 4f, and 4g have shown a significant antioxidant activity in comparison with the standard butylhydroxytoluene (BHT). Hence, compounds 3a, 4f, and 4g represent interesting dual acting antimicrobial and antioxidant agents. In fact, pyrazole derivatives bearing sulfonamide moiety (4a-g) have displayed an important antimicrobial activity compared to pyrazoles 3a-h, this finding could be attributed to the synergistic effect of the pyrazole and sulfonamide pharmacophores. Furthermore, Molecular docking results revealed a good interaction of the synthesized compounds with the target proteins and provided important information about their interaction modes with the target enzyme. The results of the POM bioinformatics investigations (Petra, Osiris, Molinspiration) show that the studied heterocycles present a very good non toxicity profile, an excellent bioavailability, and pharmacokinetics. Finally, an antiviral pharmacophore (O δ-, O δ-) was evaluated in the POM investigations and deserves all our attention to be tested against Covid-19 and its Omicron and Delta mutants.
RESUMO
Single crystals of ß-KCoFe(PO4)2, potassium cobalt(II) iron(III) bis-(ortho-phosphate), were grown from the melt under atmospheric conditions. This phosphate crystallizes isotypically with KZnFe(PO4)2 in space group C2/c, adopting a zeolite-ABW type of structure. The structure of the present phosphate is distinguished by an occupational disorder of the two transition-metal sites with ratios Fe:Co of 0.5725:0.4275 for the first and 0.4275:0.5725 for the second site. In the crystal structure, PO4 and (Co,Fe)O4 tetra-hedra are linked through vertices to form elliptical rings with the sequence DDDDUUUU of up (U) and down (D) pointing vertices. Each eight-membered ring is surrounded by four other rings of the same type, delimiting inter-stices with rectangular shape. This arrangement leads to the formation of [(Co/Fe)(PO4)]- ∞ sheets parallel to (001). Stacking of the sheets into a three-dimensional framework results in the formation of two types of channels. The first one is occupied by potassium cations, whereas the second one remains vacant. Calculations of bond-valence sums and charge distribution were used to confirm the structure model.
RESUMO
A series of novel 2-iminothiazolidin-4-one analogs have been synthesized from limonaketone, and structurally characterized by HR-MS, 1 H-NMR and 13 C-NMR spectroscopy techniques, and the structure of compound 4 was elucidated by XRD. The newly synthesized products were biologically evaluated inâ vitro for their cytotoxic activity against human cancer cell lines HT-1080, A549, and MCF-7. Thiazolidinones 9 and 10 were the most active compounds in HT-1080â cell lines (IC50 =15.85±1.75 and 16.13±1.55â µM, respectively). The apoptosis induction of the derivatives 9 and 10 were studied using annexin V staining, caspase-3/7 activity and cell cycle analysis. Compound 10 showed the highest ability of apoptosis induction and caspase-3/7 activation associated with S-phase growth arrest in HT-1080. Meanwhile, compound 9 has a moderate apoptotic effect and G0/G1-phase arrest in the after-mentioned cell. The molecular docking suggested that compounds 9 and 10 formed stable ligand-caspase-3 complexes. Besides, the presence of phenyl moiety in ligand 10 is responsible for the enhancement of the caspase-3 activation by the apparition of two additional hydrogen bonds with Cys163 and Gln161amino acids.

The title compound, C17H17BrN2O5, resulted from the 1,3-dipolar cyclo-addition reaction between dimethyl acetyl-enedi-carboxyl-ate and (3-bromo-benzyl-idene)-4-methyl-5-oxopyrazolidin-2-ium-1-ide in CHCl3. The dihedral angle between the pyrazole rings (all atoms) is 32.91â (10)°; the oxo-pyrazole ring displays an envelope conformation whereas the other pyrazole ring adopts a twisted conformation. The bromo-phenyl ring subtends a dihedral angle of 88.95â (9)° with the mean plane of its attached pyrazole ring. In the crystal, the mol-ecules are linked by C-Hâ¯O hydrogen bonds and aromatic π-π inter-actions with an inter-centroid distance of 3.8369â (10)â Å. The Hirshfeld surface analysis and fingerprint plots reveal that the mol-ecular packing is governed by Hâ¯H (37.1%), Oâ¯H/Hâ¯O (31.3%), Brâ¯H/Hâ¯Br (13.5%) and Câ¯H/Hâ¯C (10.6%) contacts. The energy framework indicates that dispersion energy is the major contributor to the mol-ecular packing.
RESUMO
Rabies is a viral zoonosis that is transmissible to humans via domestic and wild animals. There are two epidemiological cycles for rabies, the urban and the sylvatic cycles. In an attempt to study the epidemiological role of wild canidae in rabies transmission, the present study aimed to analyze the genetic characteristics of virus isolates and confirm prior suggestions that rabies is maintained through a dog reservoir in Tunisia. Virus strains isolated from wild canidae were subject to viral sequencing, and Bayesian phylogenetic analysis was performed using Beast2 software. Essentially, the virus strains isolated from wild canidae belonged to the Africa-1 clade, which clearly diverges from fox-related strains. Our study also demonstrated that genetic characteristics of the virus isolates were not as distinct as could be expected if a wild reservoir had already existed. On the contrary, the geographic landscape is responsible for the genetic diversity of the virus. The landscape itself could have also acted as a natural barrier to the spread of the virus.

In the present study, following a one-pot two-step protocol, we have synthesized novel sulfonamides-isoxazolines hybrids (3a-r) via a highly regioselective 1,3-dipolar cycloaddition. The present methodology capitalized on trichloroisocyanuric acid (TCCA) as a safe and ecological oxidant and chlorinating agent for the in-situ conversion of aldehydes to nitrile oxides in the presence of hydroxylamine hydrochloride, under ultrasound activation. These nitrile oxides could be engaged in 1,3-dipolar cycloaddition reactions with various alkene to afford the targeted sulfonamides-isoxazolines hybrids (3a-r). The latter were assessed for their antineoplastic activity against model leukemia cell lines (Chronic Myeloid Leukemia, K562 and Promyelocytic Leukemia, HL-60).

Xanthogranulomatous pyelonephritis may, rarely, occur as a renal cystic mass. We report a case report of a 50-year-old with a history of medically treated renal lithiasis, who consults for left low back pain. Imaging findings concluded to a Bosniak type-3 hemorrhagic cystic mass of the left kidney. The diagnosis of xanthogranumolatous pyelonephritis on its focal form was made histologically. The diagnosis of xanthogranulomatous pyelonephritis is often difficult even with surgical findings and frequently a histological surprise. This points out the importance of identifying it in pre-operative staging; the diagnosis may be suggested by the association of chronic pyelonephritis, renal stones and hypovascular renal tumor syndrome without specificity at sonography and CT.
RESUMO
INTRODUCTION: Penile fracture is a urologic emergency and is defined as the rupture of the tunica albuginea of the cavernous body in erection. AIM: Our study aims to evaluate patients with penile fracture and to identify the factors that may influence the sexual function after surgical repair. METHODS: A total of 138 patients who were diagnosed with penile fracture between January, 1999 and December, 2018 were reviewed. Clinical features, perioperative assessment, time from injury to surgery, tunica defect properties, and presence of urethral injury were assessed. MAIN OUTCOME MEASURES: Sexual function was evaluated by three parameters six months after surgical repair: International Index of Erectile Function-5 (IIEF-5) questionnaire, penile curvature and the presence of a painful intercourse. All factors that could potentially influence these parameters were analyzed. RESULTS: The mean age was 31.2 years (19-55). Presentation delay ranged from 1 to 5 days (mean = 16.8 hours) while surgery delay was 14.3 hours ().The most common cause of penile fracture in our patients was forcefully bending of the erect penis to achieve detumescence in 62 cases (44.9%). On multivariate analysis, we found that the presentation delay and the fracture site located in the proximal shaft of the penis showed significant difference in the occurrence of postoperative ED (P = 0.03 and P = 0.015 respectively). Presentation delay, elective incision and tuncial leak located in the proximal shaft (P = 0.045; P = 0.018 and P = 0.022 respectively) were associated with higher penis curvature. CONCLUSION: Immediate surgical repair and circumferential degloving incision for tunical leaks located in the proximal shaft of the penis are recommended in order to decrease the incidence of ED after surgical repair of penile fractures.

RESUMO
INTRODUCTION AND IMPORTANCE: Horseshoe kidney has unique anatomical features, such as a complex blood supply. We report a patient with renal tumor in a horseshoe kidney in close contact with the vena cava, who underwent open tumorectomy. CASE PRESENTATION: A 72-year-old woman was referred to our hospital with a 4-cm enhancing mid-pole mass in the right moiety of a horseshoe kidney. Open tumorectomy was performed with parenchymal clamping. The warm ischemia time was 18 min. Pathologic examination confirmed a diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins. At 3 months postoperatively, computed tomography showed no local recurrence or metastasis and renal function was intact. CLINICAL DISCUSSION: Horseshoe kidney is a rare congenital abnormality. Renal cell carcinoma is the most frequent tumor in adults having this anomaly and treatment in localised tumors if usually tumorectomy. Surgery may be challenging in some cases because of its difficulty. CONCLUSION: Open surgery remains the standard treatment for horseshoe kidney tumors because of anatomic complexity and especially in cases where the tumor is difficult to extirpate.
