Background: Heart failure (HF) in elderly patients with concurrent hypotension presents a therapeutic challenge due to limited standard HF therapies' applicability. Recombinant human brain natriuretic peptide (rhBNP) and vasoactive medications have shown potential in HF management, but their combined efficacy in elderly patients with HF and hypotension remains understudied.
Methods: This retrospective cohort study included elderly HF patients with hypotension who received rhBNP alone (Group A, n = 68), rhBNP with dobutamine (Group B, n = 74), or rhBNP with dopamine (Group C, n = 71).
Background: Ga-DOTA-FAPI-04 is a new positron imaging agent, and its application in bone metastasis has been limited. The purpose of this retrospective study was to compare the diagnostic ability of Ga-DOTA-FAPI-04 PET/CT and F-FDG PET/CT to detect bone metastases in patients with different types of cancer.
Methods: A total of 293 patients with pathologically confirmed primary malignancies were examined with Ga-DOTA-FAPI-04 PET/CT and F-FDG PET/CT within one week.
Time domain two-dimensional infrared (2DIR) spectroscopy extends the capabilities of traditional infrared spectroscopy by revealing information on vibrational modes' anharmonicities, couplings, and energy transfer processes, making it a powerful tool for studying fast dynamic processes. Recent advancements in mid-IR laser technology and detection methods have significantly improved the resolution and acquisition rate of 2DIR spectroscopy. Despite these exciting developments, 2DIR spectroscopy remains limited by Abbe's diffraction limit, which restricts its spatial resolution.

A systematic, global characterisation of AKI occurring in patients with cirrhosis is lacking. We therefore aimed to assess global differences in the characteristics, management, and outcomes of AKI in hospitalised patients with cirrhosis.

Background: Hepatitis E virus (HEV) infection is endemic in China. However, there are scarce data of HEV infection among hospital attendees seeking medical treatment or examination for various reasons.
Objective: We aim to investigate the prevalence and incidence of HEV infection by time, age, sex, and across departments in a tertiary hospital.
Metabolic-dysfunction-associated steatohepatitis (MASH) remains a major health challenge. Herein, we identify sphingomyelin phosphodiesterase 3 (SMPD3) as a key driver of hepatic ceramide accumulation through increasing sphingomyelin hydrolysis at the cell membrane. Hepatocyte-specific Smpd3 gene disruption or pharmacological inhibition of SMPD3 alleviates MASH, whereas reintroducing SMPD3 reverses the resolution of MASH.

In this study, the apparent photodegradation, photo-oxidation towards reactive oxygen species (ROS, •OH and O), and photo-modified toxicity were investigated for the four ionizable CFs: cefoxitin (CFX), cephalothin (CEF), cefoperazone (CFP) and cefazolin (CFZ). Under simulated sunlight irradiation (λ > 290 nm), their multivariate photo-transformation kinetics varied as a function of pHs and the dominant protonated states of the CF in question (HCFs, HCFs and CFs).

The APOE ε4 allele is a major genetic contributor to AD pathogenesis, with synaptic dysfunction being a central hallmark in its pathophysiology. While the role of APOE4 in reducing SNARE protein levels has been established, the underlying molecular mechanisms of this interaction remain obscure.

However, conventional detection methods relying on antigen-antibody interactions often face challenges such as high costs and lengthy procedures. Novel detection methods based on antigen-aptamer interactions offer a potentially superior alternative.

Methods: 250 CHB patients were enrolled, including treatment-naïve patients and those interrupted anti-HBV drugs for ≥ 6 months (Part A, n=125), and patients who had taken ETV for ≥1 year and had achieved viral suppression (Part B, n=125). Patients were randomly allocated to receive 120 mg GLS4/100 mg RTV plus 0.
After a stroke, abnormal changes in neural oscillations that are related to the severity and prognosis of the disease can occur. Resetting these abnormal neural oscillations is a potential approach for stroke rehabilitation. Transcranial alternating current stimulation (tACS) can modulate intrinsic neural oscillations noninvasively and has attracted attention as a possible technique to improve multiple post-stroke symptoms, including deficits in speech, vision, and motor ability and overall neurological recovery.

Quantum dot (QD) light-emitting diodes (QLEDs) are promising candidates for next-generation displays because of their high efficiency, brightness, broad color gamut, and solution-processability. Large-scale solution-processing of electroluminescent QLEDs poses significant challenges, particularly concerning the precise control of the active layer's thickness and uniformity. These obstacles directly impact charge transport, leading to current leakage and reduced overall efficiency.
