Study Design. A retrospective study of 87 patients who underwent posterior lumbar interbody
fusion (PLIF) at L4–L5 for L4 degenerative spondylolisthesis. Objective. To clarify: 1) the …

The widespread occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
has led to a pandemic of coronavirus disease 2019 (COVID-19). The S spike protein of …

Epigenetics refers to heritable changes in patterns of gene expression that occur without
alterations in DNA sequence. The epigenetic mechanisms involve covalent modifications of …

We report the observation of a narrow charmoniumlike state produced in the exclusive decay
process B±→ K±π+ π− J/ψ. This state, which decays into π+ π− J/ψ, has a mass of 3872.0±…

We present the final report from a series of precision measurements of the muon anomalous
magnetic moment, a μ=(g− 2)/2. The details of the experimental method, apparatus, data …

The T2K experiment observes indications of ν μ→ ν e appearance in data accumulated with
1.43× 10 20 protons on target. Six events pass all selection criteria at the far detector. In a …

MicroRNAs (miRs) are small noncoding RNAs that regulate gene expression by binding to
target messenger RNAs (mRNAs), leading to translational repression or degradation. Here, …

A distinct peak is observed in the π±ψ′ invariant mass distribution near 4.43 GeV in B→ K
π±ψ′ decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of M…

The ligands for programmed cell death 1 (PD-1), an immunoinhibitory receptor belonging to
CD28/cytotoxic T lymphocyte antigen 4 family, are PD-1 ligand 1 and 2 (PD-Ls). Recent …

We study B→ K (*) ℓ+ ℓ− decays (ℓ= e, μ) based on a data sample of 657× 10 6 BB pairs
collected with the Belle detector at the KEKB e+ e− collider. We report the differential branching …
