is one of the most economically important agricultural pests that cause serious crop losses worldwide, and the indiscriminate chemical application causes resistance development in a major obstacle to successful control. In this study, we selected the up-regulated expression gene , which was enriched into juvenile hormone pathway though transcriptome sequencing analysis of the cotton aphids that fed on transgenic cotton lines expressing ds (the TG cotton). The gene was overexpressed in cotton aphids which fed on the TG cotton, and its expression profile during the nymphs was clarified.

Scalp high-frequency oscillations (sHFOs) are a promising non-invasive biomarker of epilepsy. However, the visual marking of sHFOs is a time-consuming and subjective process, existing automatic detectors based on single-dimensional analysis have difficulty with accurately eliminating artifacts and thus do not provide sufficient reliability to meet clinical needs. Therefore, we propose a high-performance sHFOs detector based on a deep learning algorithm.

Background: The growth and development transition of insects are mainly mediated by ecdysone. As one of the ecdysone-induced transcription factors, E74 is involved in many physiological processes of insect growth and development. However, E74 and its function in Helicoverpa armigera remains unclear.

After myocardial injury, cardiac fibroblasts (CFs) differentiate into myofibroblasts, which express and secrete extracellular matrix (ECM) components for myocardial repair, but also promote myocardial fibrosis. Recombinant fibroblast growth factor 2 (FGF2) protein drug with low molecular weight can promote cell survival and angiogenesis, and it was found that FGF2 could inhibit the activation of CFs, suggesting FGF2 has great potential in myocardial repair. However, the regulatory role of FGF2 on CFs has not been fully elucidated.

Background and Objective: The optimization of macrocirculatory hemodynamics is recommended by current sepsis guidelines. However, microcirculatory dysfunction is considered the cause of severe sepsis. In the present study, we designed to verify whether the application of Shenfu injection (SFI) restores microcirculation, thereby improving tissue perfusion and inhibiting organ dysfunction, resulting in improved outcomes.

Smoothened is a key receptor of the hedgehog pathway, but the roles of Smoothened in cardiac development remain incompletely understood. In this study, we found that the conditional knockout of from the mesoderm impaired the development of the venous pole of the heart and resulted in hypoplasia of the atrium/inflow tract (IFT) and a low heart rate. The blockage of led to reduced expression of genes critical for sinoatrial node (SAN) development in the IFT.

Coronavirus disease 2019 (COVID-19) broke out in December 2019. Due its high morbility and mortality, it is necessary to summarize the clinical characteristics of COVID-19 patients to provide more theoretical basis for future treatment. In the current study, we conducted a retrospective analysis of the clinical characteristics of COVID-19 patients and explored the risk factors for the severity of illness.

Article Synopsis
  • This study looked at 47 COVID-19 patients in an ICU in Wuhan, China, to identify risk factors for mortality.
  • Results showed that patients who died had higher rates of septic shock and worse scores on assessment scales like SOFA and APACHE II compared to survivors.
  • Key findings indicated that a higher SOFA score and a lower lymphocyte count at admission were significant independent risk factors for poor outcomes in these patients.

Background: The novel 2019 coronavirus (COVID-19) has largely abated in China; however, sporadic or imported cases are still a concern, while in other countries, the COVID-19 pandemic persists as a major health crisis.

Methods: All patients enrolled in this study were diagnosed with COVID-19 from February 21, 2020 to April 14, 2020 in Wuhan. We retrospectively analyzed the patients admitted to the ICU (137 patients) and general wards (114 patients) of Wuhan Leishenshan Hospital in China.

Purpose: Tanshinone IIA (Tan IIA), a compound extracted from , can improve type II diabetes, while the molecular mechanisms underlying Tan IIA-mediated protective effects in diabetic nephropathy are unclear. This study explored the protective actions of Tan IIA on renal tissues in streptozotocin (STZ)-induced diabetic nephropathy.

Materials And Methods: Tan IIA (2, 4, 8 mg/kg/day) was daily administered to STZ-treated rats by intraperitoneal injection for 42 days.

  • Nucleic acid detection methods are essential for diagnosing diseases, especially during the COVID-19 pandemic, but existing techniques have limitations in speed and accuracy.
  • The innovative CRISPR-Cas9-assisted DNA detection (CADD) method was developed to overcome these challenges by using specific guide RNAs and a rapid incubation process at room temperature.
  • This new technique can quickly detect various DNA samples, including those from high-risk human papillomaviruses in clinical samples, and can yield results in just 30 minutes, making it suitable for on-the-spot testing.

Flavonoids are extensively distributed secondary metabolites in land plants. They play a critical role in plant evolution from aquatic to terrestrial and plant adaption to ultraviolet radiation. However, the downstream branching pathway of flavonoids and its regulatory mechanism in bryophytes, which are the most ancient of terrestrial plants, remain unclear.

The fast and cost-effective DNA extraction is critical for all DNA-based detections. Here, we fabricated a new kind of polyacrylamide microsphere (PAMMP) in various sizes with two methods, spot polymerization (large size but low yield) and modified inverse microemulsion polymerization (small size but high yield). The fabricated PAMMPs have strong autofluorescence (fPAMMPs), including both visible fluorescence (VF) and near-infrared fluorescence (NIRF), which can remain very stable in various stringent conditions including strong acid and alkali and high temperature.

Article Synopsis
  • Researchers created a new technique, called CRISPR-assisted enhancer, to improve the efficiency of gene activation using the deactivated CRISPR/Cas9 system (dCas9).
  • This method combines dCas9 with a powerful CMV enhancer and uses two different systems to recruit the enhancer to target genes.
  • The new approach significantly boosts gene expression compared to traditional dCas9 activators, working effectively on both introduced reporter genes and natural genes in various cell types.

Cancer is caused by a series of alterations in genome and epigenome and exists in multiple complex forms, making it difficult to be prevented and/or treated. Telomerase, an enzyme responsible for the maintenance of telomere, is silent in most normal somatic cells but activated in 90% of cancer cells, making it an excellent target for cancer therapy. Therefore, various telomerase activity inhibitors have been developed to treat cancer but all failed due to side effects.

This study develops a new method for detecting and typing target DNA based on Cas9 nuclease, which was named as ctPCR, representing Cas9-sgRNA- or CRISPR-typing PCR. The technique can detect and type target DNA easily, rapidly, specifically, and sensitively. This technique detects target DNA in three steps: (1) amplifying target DNA with PCR by using a pair of universal primers (PCR1); (2) treating PCR1 products with a process referred to as CAT, representing Cas9 cutting, A tailing and T adaptor ligation; (3) amplifying the CAT-treated DNA with PCR by using a pair of general-specific primers (gs-primers) (PCR2).

Many diseases are associated with the abnormal activation of NF-κB and its signaling pathway. NF-κB has become an important target for disease treatment and development of new drugs. Many various NF-κB inhibitors were therefore developed; however, they have difficulties to become clinical drugs due to their adverse side effects resulted from the affected normal physiological functions of this transcription factor.
