Co-exposure to high PM2.5 and extreme heat exacerbates cognitive decline in middle-aged and elderly Chinese people

Hygiene and Environmental Health Advances
Cognitive impairment is an increasingly public health concern. However, limited evidence exists regarding the combined effects of fine particulate matter (PM2.5) and extreme heat exposure on cognitive function.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Whole-body PET acceptance test in 2D and 3D using NEMA NU 2-2001 protocol

Journal of Medical Physics, 2007
Integrated PET/CT has emerged as an integral component of oncology management because of its unique potential of providing both functional and morphological images in a single imaging session.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

PCSNet-YOLOv12: YOLOv12-Based Target Detection Model for Winged Aphids on Sticky Traps with Precise Coordinate Synergy Network

Agriculture
In the field of smart plant protection, accurate early monitoring of winged aphids is critical, as it enables the interruption of viral disease transmission and reduces dependence on pesticides.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

The $n$-Color Partition Function and Some Counting Theorems [PDF]

Recently, Merca and Schmidt found some decompositions for the partition function $p(n)$ in terms of the classical Möbius function as well as Euler\u27s totient. In this paper, we define a counting function $T_k^r(m)$ on the set of $n$-color partitions of

A function-field analogue of the Goldbach counting function and the associated Dirichlet series

, 2023
We consider a function-field analogue of Dirichlet series associated with the Goldbach counting function, and prove that it can, or cannot, be continued meromorphically to the whole plane.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Proving the heuristic asymptotic formula for prime counting function

This is a follow up paper to the a previous paper written by the same author. In this paper we prove that the heuristic formula for the prime counting function derived in the previous paper \cite{1} actually approaches the same value as the prime ...
