Candidemia is defined as being a yeast infection confirmed by the presence of at least one positive Candida blood culture. it is a life threatening infection causing high mortality. The clinical signs are generally compatible with the causative agent (whether there is a deep venous catheter or not). On the other hand and according to the 2012 Revised chapel Hill Classification, granulomatosis with polyangiitis GPA is classified as a vasculitis associated with antineutrophil cytoplasmic antibodies ANCA. it is a systemic disease characterized by the anatomopathological aspect of granuloma. We report the case of a patient who presented an atypical and a very rare revealing mode of GPA which was a bronchopulmonary candidiasis complicated by candidemia. despite its controversy, the combination in the acute phase of antifungal treatment based on intravenous voriconazole and glucocorticoid therapy has made it possible to control candidemia and calm vasculitis.

Recently, a bulk nickelate superconductor La_(3)Ni_(2)O_(7) is discovered at pressures with a remarkable high transition temperature T_(c)~ 80 K. Here, we study a Hubbard model with tight-binding parameters derived from ab initio calculations of La_(3)Ni_(2)O_(7),by employing large scale determinant quantum Monte Carlo and cellular dynamical mean-field theory. Our result suggests that the superexchange couplings in this system are comparable to that of cuprates. The system is a charge transfer insulator as the hole concentration becomes four per site at large Hubbard U. Upon hole doping, two low-energy spin-singlet bands emerge in the system exhibiting distinct correlation properties: while the one composed of the out-of-plane Ni-d_(3z^(2)-r^(2)) and O-p_(z) orbitals demonstrates strong antiferromagnetic correlations and narrow effective bandwidth, the in-plane singlet band consisting of the Ni-d_(x^(2)-y^(2)) and O-p_(x)/p_(y) orbitals is in general more itinerant. Over a broad range of hole doping, the doped holes occupy primarily the d_(x^(2)-y^(2)) and p_(x)/p_(y) orbitals, whereas the d_(3z^(2)-r^(2)) and p_(z) orbitals retain underdoped. We propose an effective t-J model to capture the relevant physics and discuss the implications of our result for comprehending the La_(3)Ni_(2)O_(7) superconductivity.

Many phenomena in nature and technology are associated with the filtration of suspensions and colloids in porous media. Two main types of particle deposition,namely, cake filtration at the inlet and deep bed filtration throughout the entire porous medium, are studied by different models. A unified approach for the transport and deposition of particles based on the deep bed filtration model is proposed. A variable suspension flow rate, proportional to the number of free pores at the inlet of the porous medium, is considered. To model cake filtration, this flow rate is introduced into the mass balance equation of deep bed filtration. For the cake filtration without deposit erosion,the suspension flow rate decreases to zero, and the suspension does not penetrate deep into the porous medium. in the case of the cake filtration with erosion, the suspension flow rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact solution is obtained for a constant filtration function. The method of characteristics is used to construct the asymptotics of the concentration front of suspended and retained particles for a filtration function in a general form. Explicit formulae are obtained for a linear filtration function. The properties of these solutions are studied in detail.

The hydrothermal synthesis of in_(2)O_(3)and CeO_(2)–in_(2)O_(3)is investigated as well as the properties of sensor layers based on these *** the synthesis of in_(2)O_(3),intermediate products in(OH)_(3)and inOOH are formed,which are the precursors of stable cubic(c-in_(2)O_(3))and metastable rhombohedral(rh-in_(2)O_(3))phases,respectively.A transition from c-in_(2)O_(3)to rh-in_(2)O_(3)is observed with the addition of CeO_(2).The introduction of cerium into rh-in_(2)O_(3)results in a decrease in the sensor response to hydrogen,while it increases in composites based on c-in_(2)O_(3).The data on the sensor activity of the composites correlate with XPS results in which CeO_(2)causes a decrease in the concentrations of chemisorbed oxygen and oxygen vacancies in rh-in_(2)O_(3).The reverse situation is observed in composites based on c-in_(2)O_(3).Compared to in_(2)O_(3)and CeO_(2)–in_(2)O_(3)obtained by other methods,the synthesized composites demonstrate maximum response to H_(2)at low temperatures by 70–100℃,and have short response time(0.2–0.5 s),short recovery time(6–7 s),and long-term stability.A model is proposed for the dependence of sensitivity on the direction of electron transfer between in_(2)O_(3)and CeO_(2).

introduction: HiV, the human immunodeficiency virus, is the etiological agent of acquired immunodeficiency syndrome (AidS). The aim of this study was to assess the evolution of the viral load in patients under treatment. Methodology: This was a study carried out from July 2017 to June 2022 at the Point G University Hospital laboratory. The determination of the viral load of patients was carried out by PCR on the ABOTT M2000sp/rt platform. Results: A total of 129 patients infected with HiV-1, aged 19 to 72 years with a mean age of 40.05 years ± 10.71;all on antiretroviral chemotherapy. The female gender predominated among our patients. The most common treatment regimen was 2iNTi + 1iNNTi with 72.9% followed by 2iNTi + 1iNi with 13.2%. As for the combinations of molecules, the combination TdF + 3TC + EFV and TdF + 3TC + dTG predominated, respectively 65.1% and 13.2%. 89.9% of our patients had undetectable viremia after 12 months of treatment (p ith an average viral load which had evolved from 681315.65 copies/ml ± 1616908.484 to M0 at 5742.36 copies /ml ± 35756.883 at M12 (p Conclusion: Generally speaking, antiretroviral treatment had contributed to controlling viral loads, however the therapeutic combination TdF + 3TC + dTG had made it possible to obtain more patients with undetectable viremia instead.
