The proton (H) has been proved to be another important energy storage ion besides Zn in aqueous zinc-inorganic batteries with moderate electrolytes. H storage usually possesses better thermodynamics and reaction kinetics than Zn, and is found to be an important addition for Zn storage. Thus, understanding, characterizing, and modulating H storage in inorganic cathode materials is particularly important.

Breast cancer (BC) is the most common malignancy among women and a leading cause of cancer-related deaths of females worldwide. It is a complex and molecularly heterogeneous disease, with various subtypes that require different treatment strategies. Despite advances in high-resolution single-cell and multinomial technologies, distant metastasis and therapeutic resistance remain major challenges for BC treatment.

The Yellow River water of an urban area located in the middle and lower reaches of the Yellow River was taken as the research object, in which the seasonal and along-range distribution of total culturable bacteria, typical antibiotic resistant bacteria (amoxicillin resistant bacteria and sulfamethoxazole-resistant bacteria), and their corresponding typical resistance genes [-lactam resistance gene () and sulfamamide resistance genes ( and ), as well as were investigated. The results showed that the total culturable bacteria, -lactam-resistant bacteria and sulfonamide-resistant bacteria in the Yellow River Basin were significantly affected by temperature and human activities. The composition and quantity of their genera had obvious spatiotemporal distribution characteristics, in which and were dominant in the composition and number of bacteria.

Effective screening and early detection are critical to improve the prognosis of gastric cancer (GC). Our study aims to explore noninvasive multianalytical biomarkers and construct integrative models for preliminary risk assessment and GC detection. Whole genomewide methylation marker discovery was conducted with CpG tandems target amplification (CTTA) in cfDNA from large asymptomatic screening participants in a high-risk area of GC.

This study aimed to investigate the relationship between the promoting effect of Zuogui Pills on ovarian and vaginal angiogenesis in early-aging rats and mobilization factors granulocyte-macrophage colony-stimulating factor(GM-CSF), stromal cell-derived factor-1(SDF-1), and their receptors of endothelial progenitor cells(EPCs) and explore the mechanism of Zuogui Pills in improving reproductive hypofunction in early-aging rats. Ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) was used to analyze the chemical components of the extract of Zuogui Pills. Forty 14-month-old female early-aging rats with estrous cycle disorder were randomly divided into a blank group, a conjugated estrogen group(conjugated estrogen suspension, 65 μg·kg~(-1)), and low-(11 g·kg~(-1)) and high-dose(33 g·kg~(-1)) Zuogui Pills groups, with 10 rats in each group.

Objective: Systemic chemotherapy is the first-line therapeutic option for head and neck squamous cell carcinoma (HNSCC), but it often fails. This study aimed to develop an effective prognostic model for evaluating the therapeutic effects of systemic chemotherapy.

Methods: This study utilized CRISPR/cas9 whole gene loss-of-function library screening and data from The Cancer Genome Atlas (TCGA) HNSCC patients who have undergone systemic therapy to examine differentially expressed genes (DEGs).

Article Synopsis
  • The study aimed to understand COVID-19 transmission dynamics during the early pandemic by analyzing a large dataset of cases and their potential transmission pairs.
  • Findings showed that the median incubation period was 7.2 days, with children under 18 having longer incubation periods compared to adults.
  • The research highlighted that peak infectivity happened one day before symptoms appeared, indicating that a significant portion of transmission occurred during the incubation period, which underscores the need for strict control measures like early case detection and quarantining contacts.

Objective: The aim of this study was to detect single nucleotide polymorphisms (SNP) of G protein-coupled receptor 54 (GPR54) gene and explore association of this candidate gene with reproductive traits in Jiaxing Black sows.

Methods: Six pairs of primers of the gene were designed to amplify all exons thus sequences of which were detected by means of direct sequencing and then SNP loci were scanned. The effects of SNPs on total number of piglets born (TNB), number of piglets born alive (NBA), number of still born piglets (NSB), and litter weight at birth (LWB) of Jiaxing Black sows were analyzed.

To investigate breed characteristics and the effect of hybridization of Jiaxing Black Pig (JBP) with Western breeds, the carcass and meat quality traits and flavor substances such as inosinic acids (IMP), intramuscular fat (IMF) in longissimus muscle (LM) from five breeds including JBP, Berkshire, Berkshire × JBP (BJBP), Duroc × Berkshire × JBP (DBJBP), Duroc × Landrace × JBP (DLJBP) were compared in this study. It was found that water holding capacity (WHC) of LM in JBP was significantly higher than that in the other strains (p < 0.01).

Article Synopsis
  • Researchers have developed a low-power 2×2 thermo-optic switch using an X-junction design with a silicon oxynitride (SiON) core and polymer cladding.
  • The innovative design incorporates a slot in the center of the X-junction, optimizing the different thermo-optic properties of SiON and the polymer for better heat efficiency.
  • The experimental switch demonstrates impressive performance with an extinction ratio above 15.34 dB, low switching power of about 59.6 mW, fast switching times (1.42 ms rise and 0.85 ms fall), and minimal insertion and polarization-dependent losses.

A scalable and reconfigurable on-chip optical true time delay line consisting of Mach-Zehnder interferometer (MZI) switches and delay waveguides is proposed and demonstrated with the ultra-low-loss silica waveguide platform. The MZI switches provide the reconfiguration of the light traveling paths and hence different delays. Our proposed structure can be easily scaled to an M bit delay line with a slight increase in dimensions.

Article Synopsis
  • Glucocorticoids (GCs) are commonly prescribed for various conditions like asthma and arthritis but can be ineffective for some patients, leading to GC resistance.
  • This resistance is a significant challenge in treatment and highlights the need for better solutions.
  • The article focuses on how genetic differences affect individual responses to GCs, reviewing the pharmacogenetics involved in their effectiveness for different diseases.

Radiofrequency ablation (RFA) is one of the treatment modes for liver cancer. The trauma caused by RFA is small, and its local curative effect is reliable. Computed tomography (CT) can only be used for axial scans, and parts of the lesion are unclear on plain scans.

Article Synopsis
  • - The H5N2 influenza virus, isolated from a symptomatic dog in China in 2009, has been confirmed to transmit between dogs but its transmission to other species was unclear.
  • - Contact exposure experiments were conducted with susceptible cats and chickens housed near infected dogs, revealing that one cat showed clear infection and others had seroconversion, while eight chickens displayed signs of illness and two died.
  • - The results suggest that close contact with H5N2-infected dogs can lead to the virus spreading to both cats and chickens, indicating possible interspecies transmission.

In 2009, an influenza virus (IV), A/canine/Shandong/JT01/2009 (CA/SD/JT01/09), was isolated from the dog exhibiting respiratory signs in China, and was a novel H5N2. Intraspecies transmission of the virus in dog population had thus far remained unclear. To determine whether the novel H5N2 was transmitted among dogs, we conducted contact exposure and inoculation experiments.
