To investigate the effects of nitrogen (N) application rate and planting density (D) on the contents of lipid and free fatty acid, fatty acid composition, yield and quality of rice grain, a field experiment was conducted using Koshihikari (japonica) as experimental material from 2021 to 2022 with three N levels (90, 150 and 210 kg ha, denoted as N1, N2 and N3, respectively) and three transplanting densities (19.0 × 10, 26.7 × 10 and 40.

Reasonable nitrogen (N) and potassium (K) application rates can effectively improve fertilizer use efficiency, rice yield and quality. A two-year field experiment was conducted with combined application of three N rates (135, 180, and 225 kg ha, denoted as N1-N3) and four K rates (0, 90, 135, and 180 kg ha, denoted as K0-K3) using super indica hybrid rice cultivar Yixiangyou (YXY) 2115 to explore the effects of co-application of N and K on rice growth and development. The results indicated that the combined application of N and K had significantly interactive effects on dry matter (DM) accumulation, nutrients absorption, N harvest index (NHI), K harvest index (KHI), spikelets per panicle and most rice quality indexes.

Article Synopsis
  • Gastric ulcers (GU) are common and have serious health impacts, with Ruda-6 (RD-6) showing promise as a treatment based on traditional Mongolian medicine.
  • Researchers conducted a comprehensive study using network analysis and RNA sequencing to uncover how RD-6 protects against GU by identifying its targets and pathways.
  • The results indicated that RD-6 significantly improved gastric damage and reduced inflammation through the IL-17 signaling pathway, implicating specific genes in its therapeutic effects.

Federated learning (FL) and split learning (SL) are two emerging collaborative learning methods that may greatly facilitate ubiquitous intelligence in the Internet of Things (IoT). Federated learning enables machine learning (ML) models locally trained using private data to be aggregated into a global model. Split learning allows different portions of an ML model to be collaboratively trained on different workers in a learning framework.

Article Synopsis
  • - Euphorbiaceae is a plant family mainly found in tropical and subtropical regions, known for its economic importance due to products like rubber, oil, and medicinal materials.
  • - The study identified 244 glutathione S-transferase (GST) genes across four Euphorbiaceae species, realizing that these proteins are crucial for functions like detoxification, stress response, and growth regulation.
  • - Analysis revealed that Euphorbiaceae GST genes are evolutionarily conserved and grouped into 10 subfamilies, with findings suggesting their specific roles in stress resistance and herbicide detoxification, laying groundwork for future research.

Purpose: To observe the effect of a brain-computer interface-operated lower limb rehabilitation robot (BCI-LLRR) on functional recovery from stroke and to explore mechanisms.

Methods: Subacute-phase stroke patients were randomly divided into two groups. In addition to the routine intervention, patients in the treatment group trained on the BCI-LLRR and underwent the lower limb pedal training in the control group, both for the same time (30 min/day).

The relationship between right to left shunt (RLS) and non-headache symptoms (NHS) in episodic migraine is unknown. This study aimed to investigate the incidence and classification of RLS in episodic migraineurs, calculate the occurrence rate of NHS, and analyze the associations between RLS and NHS. We consecutively recruited 204 episodic migraine patients.

Recently, numerous microRNAs (miRNAs) have been considered as key players in the regulation of neuronal processes. The purpose of the present study is to explore the effect of miR-25 on hippocampal neuron injury in Alzheimer's disease (AD) induced by amyloid β (Aβ) peptide fragment 1 to 42 (Aβ1-42) via Kruppel-like factor 2 (KLF2) through the nuclear factor-E2-related factor 2 (Nrf2) signaling pathway. A mouse model of AD was established through Aβ1-42 induction.

Data fusion in the Internet of Things (IoT) environment demands collecting and processing a wide variety of data with mixed time characteristics, both real-time and non-real-time data. Most of the previous research on data fusion was about the data processing aspect; however, successful data transmission is a prerequisite for high-performance data fusion in IoT. On the other hand, research on data transmissions in IoT mainly focuses on networking without sufficiently considering the special requirements of the upper-layer applications, such as the data fusion process, that are consuming the transmitted data.

Rationale: Acute compartment syndrome is a highly aggressive condition, which needs rapid diagnosis and surgical emergency. Most cases are caused by trauma, fractures, surgeries, or vascular injury, while other causes are easily misdiagnosed.

Patients Concerns: A 29-year-old female, with a medical history of an insect bite on the left calf but not recent trauma, was admitted to the hospital due to the swelling and pain around the bite area.

Background: Both high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) and low-frequency rTMS (LF-rTMS) are reported to benefit upper limb motor function rehabilitation in patients with stroke. However, the efficacy of combining LF- and HF-rTMS (LF-HF rTMS) has not been adequately explored, especially in the early phase of stroke.

Objective: To compare the effects of LF- and LF-HF rTMS on the upper limb motor function in the early phase post stroke.

A field plot experiment was conducted to study the effects of seed dressing with imidacloprid at the pesticide/seed mass ratios of 6:10000, 9:10000, and 12:10000 on the seedlings growth and protective enzyme activities of high-yielding summer maize. Seed dressing with an imidacloprid/seed mass ratio of 6:10000 increased the seedlings height, primary root length, secondary root number, aboveground fresh mass, and underground fresh mass by 2.81 cm, 2.
