Lattice Dynamics of CuZnSn(S ,Se ) Kesterite Thin-Film Solar Cells Studied by Nuclear Inelastic Scattering.

Phonons play a crucial role in thermalization and non-radiative recombination losses in semiconductors, impacting the power conversion efficiency of solar cells. To shed light on the lattice dynamics in CuZnSn(S ,Se ) (CZTSSe) thin-film solar cells and validate the extensive number of theoretical studies, we determine the Sn-partial phonon density of states (Sn-PDOS) by nuclear inelastic X-ray scattering. CZTSSe-based devices, one with near-stoichiometric and two with off-stoichiometric compositions, are investigated, and the results are correlated with the corresponding power conversion efficiencies (PCEs) of 3.

Comparison of the structure-function properties of wild-type human apoA-V and a C-terminal truncation associated with elevated plasma triglycerides.

Background: Plasma triglycerides (TGs) are causally associated with coronary artery disease and acute pancreatitis. Apolipoprotein A-V (apoA-V, gene ) is a liver-secreted protein that is carried on triglyceride-rich lipoproteins and promotes the enzymatic activity of lipoprotein lipase (LPL), thereby reducing TG levels. Little is known about apoA-V structure-function; naturally occurring human variants can provide novel insights.

Gene editing for dyslipidemias: New tools to "cut" lipids.

Effective lipid lowering therapies are essential for the prevention of atherosclerosis and cardiovascular disease. Available treatments have evolved in both their efficacy and their frequency of administration, and currently include monoclonal antibodies, antisense oligonucleotides and siRNA approaches. However, an unmet need remains for more effective and long-lasting therapeutics.

Phonon confinement and interface lattice dynamics of ultrathin high- rare earth sesquioxide films: the case of EuO on YSZ(001).

The spatial confinement of atoms at surfaces and interfaces significantly alters the lattice dynamics of thin films, heterostructures and multilayers. Ultrathin films with high dielectric constants (high-) are of paramount interest for applications as gate layers in current and future integrated circuits. Here we report a lattice dynamics study of high- EuO films with thicknesses of 21.

ILRUN Promotes Atherosclerosis Through Lipid-Dependent and Lipid-Independent Factors.

Background: Common genetic variation in close proximity to the gene are significantly associated with coronary artery disease as well as with plasma lipid traits. We recently demonstrated that hepatic inflammation and lipid regulator with ubiquitin-associated domain-like and NBR1-like domains (ILRUN) regulates lipoprotein metabolism in vivo in mice. However, whether ILRUN, which is expressed in vascular cells, directly impacts atherogenesis remains unclear.

History of Rabies Incidence and Rabies Control in Serbia in Support of the Zero by 2030 Campaign to Eliminate Dog-Mediated Human Rabies.

Urban (principally canine-mediated) rabies has been a public health risk for people living in Serbia for centuries. The first legal act in urban rabies prevention in Serbia was established in 1834 by introducing high taxes for pet dog owners. Five years later in 1839, the first set of literature describing rabies prevention was issued by the health department from The Serbian Ministry of Interior.

Lattice Dynamics and Structural Phase Transitions in EuO.

Using the density functional theory, we study the structural and lattice dynamical properties of europium sesquioxide (EuO) in the cubic, trigonal, and monoclinic phases. The obtained lattice parameters and energies of the Raman modes show a good agreement with the available experimental data. The Eu-partial phonon density of states calculated for the cubic structure is compared with the nuclear inelastic scattering data obtained from a 20 nm thick EuO film deposited on a YSZ substrate.

Application of Date ( L.) Fruit in the Composition of a Novel Snack Bar.

The aim of the present study was to evaluate the possibilities for using date fruit from the Kingdom of Saudi Arabia in the formulation of a novel snack bar while replacing the used honey with date paste. The technological, textural, microbiological and sensory qualities of the obtained food products were evaluated during storage for 12 days after their production. Date palm fruit in the form of date paste was used as an ingredient in the composition of the new snack bars that also included nuts and dried fruits.

Tick-Borne Encephalitis Virus Seropositivity among Tick Infested Individuals in Serbia.

Tick-borne encephalitis (TBE), caused by the TBE virus (TBEV), is a life-threatening disease with clinical symptoms ranging from non-specific to severe inflammation of the central nervous system. Despite TBE is a notifiable disease in Serbia since 2004, there is no active TBE surveillance program for the serologic or molecular screening of TBEV infection in humans in the country. This prospective cohort study aimed to assess the TBEV exposure among tick-infested individuals in Serbia during the year 2020.

Possibility of Immediate Introduction of a Single-Dose Antibody Induction Test as a Refinement of the NIH Test for Inactivated Rabies Vaccine Potency Determination.

Antibody induction test (AIT) is a promising candidate as a refinement of the troublesome National institutes of Health (NIH) test in the sense of animal welfare 3R approach for determination of potency of inactivated rabies vaccines for veterinary and human use. In this study, we initially try to develop AIT as a suitable alternative to NIH test, to achieve a reduction of test duration and diminish animal suffering by omitting intracerebral CVS infection and measuring humoral immunity upon vaccination. Designs of both multi-dose and single-dose AIT were examined.

Reduction of Autophagic Accumulation in Pompe Disease Mouse Model Following Gene Therapy.

Background: Pompe disease is a fatal neuromuscular disorder caused by a deficiency in acid α-glucosidase, an enzyme responsible for glycogen degradation in the lysosome. Currently, the only approved treatment for Pompe disease is enzyme replacement therapy (ERT), which increases patient survival, but does not fully correct the skeletal muscle pathology. Skeletal muscle pathology is not corrected with ERT because low cation-independent mannose-6-phosphate receptor abundance and autophagic accumulation inhibits the enzyme from reaching the lysosome.

Phonon confinement and spin-phonon coupling in tensile-strained ultrathin EuO films.

Reducing the material sizes to the nanometer length scale leads to drastic modifications of the propagating lattice excitations (phonons) and their interactions with electrons and magnons. In EuO, a promising material for spintronic applications in which a giant spin-phonon interaction is present, this might imply a reduction of the degree of spin polarization in thin films. Therefore, a comprehensive investigation of the lattice dynamics and spin-phonon interaction in EuO films is necessary for practical applications.

Anomalous Lattice Dynamics of EuSi_{2} Nanoislands: Role of Interfaces Unveiled.

We report a systematic lattice dynamics study of EuSi_{2} films and nanoislands by in situ nuclear inelastic scattering on ^{151}Eu and ab initio theory. The Eu-partial phonon density of states of the nanoislands exhibits anomalous excess of phonon states at low and high energies, not present in the bulk and at the EuSi_{2}(001) surface. We demonstrate that atomic vibrations along the island-substrate interface give rise to phonon states both at low and high energies, while atomic vibrations across the island-island interface result in localized high-energy phonon modes.

Genetic and Epigenetic Drug Targets in Myelodysplastic Syndromes.

Background: Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal disorders of hematopoietic system, characterized by genetic, epigenetic or microenvironmental alterations of aging hematopoietic stem cells. Pathophysiology of MDS comprises the suppression of normal hematopoiesis and reduced myeloid progenitor cells differentiation, with the main consequence of peripheral cytopenias and increased risk to evolution in acute myeloid leukemia (AML).

Method: This review summarizes the evolving understanding of the role of genetic and epigenetic alterations involved in pathogenesis and current and future strategies for therapeutic targeting in myelodysplastic syndromes.
