We propose a method for object localization in fluorescent tomography (FT) in the presence of a highly heterogeneous background. Existing approaches typically assume a homogeneous background distribution; thus, they are incapable of accurately accounting for the more general case of an unconstrained, possibly heterogeneous, background. The proposed method iteratively solves the inverse problem over a solution space partitioned into a background subspace and an object subspace to simultaneously estimate the background and localize the target fluorescent objects. Simulation results of this algorithm applied to continuous-wave FT demonstrate effective localization of target objects in the presence of highly heterogeneous background distributions.

Background: In clinical practice, creative arts therapy is frequently utilized for the treatment of traumatized adults, with reports of favorable outcomes. However, the effectiveness of this intervention in post-traumatic stress disorder (PTSD) treatment has not yet been definitively established through meta-analysis. In this meta-analysis, we aim to assess the effectiveness of creative arts therapy in the management of PTSD.

Background: Previous studies have indicated that retinol and vitamin D may be associated with the oncogenesis of tongue cancer. Therefore, we aimed to assess the causal relationships of retinol and vitamin D with the risk of tongue cancer using the two-sample Mendelian randomization (MR) method.
Methods: Single nucleotide polymorphisms (SNPs) related to retinol, vitamin D and tongue cancer were obtained from the up-to-date genome-wide association study (GWAS) catalogue, which was screened for instrumental variables (IVs).
Background: FT596 is an induced pluripotent stem-cell (iPSC)-derived chimeric antigen receptor (CAR) natural killer (NK) cell therapy with three antitumour modalities: a CD19 CAR; a high-affinity, non-cleavable CD16 Fc receptor; and interleukin-15-interleukin-15 receptor fusion. In this study, we aimed to determine the recommended phase 2 dose (RP2D) and evaluate the safety and tolerability of FT596 as monotherapy and in combination with rituximab. We also aimed to evaluate the antitumour activity and characterise the pharmacokinetics of FT596 as monotherapy and in combination with rituximab.

Background: Early-onset major depressive disorder (EO-MDD) is characterized by its significant heterogeneity, hindering progress in research. Traditional case-control studies, like group-level structural covariance network, struggle to capture individual heterogeneity among EO-MDD patients.
Methods: In this study, T1-weighted structural magnetic resonance imaging was obtained from 185 participants, including 103 EO-MDD patients and 82 healthy controls.
