This paper was aimed to investigate the impact of the extraction from raspberry on the Alzheimer disease model protein expression. According to weight, the ovariectomized mice were randomly divided into shame operation group, model group, estrogen positive control group(0.1 g•L⁻¹) and ethyl acetate extraction part control group(in dose of 18 g•kg⁻¹). Each mouse in positive control group was subcutaneous injected of estradiol with 0.2 mL every two days. Raspberry effective parts group were given 0.01 mL•g⁻¹ raspberry ethylacetate extracts, model group and control group were given 0.01 mL•g⁻¹ saline once a day. The drug administration lasted for 32 days. Proteins from mice's hippocampus were extracted, then Nanol-ESI liquid-mass spectrometry system was used for detection and ProteinDiscovery software was used for identification to qualitative analysis different groups of hippocampal proteins by using the software of SIEVE. The results showed that model group compared with the mice of ethyl acetate extraction part control group have 66 differentially expressed proteins including heat shock protein, microtubule protein, protein involved in energy metabolism and protein of brain protection related proteins associated with AD. Those differences protein may be the target that Raspberry prevention and treatment of AD.

Chromatin enables precise and scalable gene regulation with factors of limited specificity.

Biophysical constraints limit the specificity with which transcription factors (TFs) can target regulatory DNA. While individual nontarget binding events may be low affinity, the sheer number of such interactions could present a challenge for gene regulation by degrading its precision or possibly leading to an erroneous induction state. Chromatin can prevent nontarget binding by rendering DNA physically inaccessible to TFs, at the cost of energy-consuming remodeling orchestrated by pioneer factors (PFs).

In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature-dependent sex determination (TSD).

Precipitation recycling, where evapotranspiration (ET) from the land surface contributes to precipitation within the same region, is a critical component of the water cycle. This process is especially important for the US Corn Belt, where extensive cropland expansions and irrigation activities have significantly transformed the landscape and affected the regional climate. Previous studies investigating precipitation recycling typically relied on analytical models with simplifying assumptions, overlooking the complex interactions between groundwater hydrology and agricultural management.

Objective: This study focuses on epidermal growth factor receptor-mutated lung adenocarcinoma, known for frequent brain metastasis. It aimed to compare the clinical outcomes and cost-effectiveness of combining Gamma Knife radiosurgery (GKRS) with tyrosine kinase inhibitors (TKIs) (GKRS+TKI group) versus TKIs alone (TKI group) for the treatment of patients with newly diagnosed brain metastasis in this condition.
Methods: Study characteristics of the two groups were matched using inverse probability of treatment weighting (IPTW).
Identification and validation of soft tissue sarcoma-specific transcriptomic model for predicting radioresistance.

Purpose: We aimed to identify the transcriptomic signatures of soft tissue sarcoma (STS) related to radioresistance and establish a model to predict radioresistance.
Materials And Methods: Nine STS cell lines were cultured. Adenosine triphosphate-based viability was determined 5 days after irradiation with 8 Gy of X-rays in a single fraction.
