Courtship interactions are remarkably diverse in form and complexity among species. How neural circuits evolve to encode new behaviors that are functionally integrated into these dynamic social interactions is unknown. Here we report a recently originated female sexual behavior in the island endemic Drosophila species D.

How neural circuits evolve to encode new behaviors that are functionally integrated into these dynamic social interactions is unknown. Here we report a recently originated female sexual behavior in the island endemic species , where females signal receptivity to male courtship songs by spreading their wings, which in turn promotes prolonged songs in courting males.

- Plumbene, similar to graphene, shows promise for enhancing superconducting critical temperature (T) due to strong spin-orbit coupling.
- A study of a buckled plumbene-Au Kagome superstructure reveals it has a higher superconducting gap than both monolayer and bulk lead (Pb) substrates.
- The research confirms this enhanced superconductivity through advanced techniques, suggesting that the combination of plumbene and Au layers activates unique electronic properties.
Article Synopsis
- Monolayer transition metal dichalcogenides, like MoS and PtTe, show promise for developing advanced electronics due to their tunable electronic properties.
- Using scanning tunneling microscopy/spectroscopy, researchers found that the bandgap of MoS decreases logarithmically with increased tunneling current, illustrating an electric-field-induced gap renormalization.
- In contrast, PtTe exhibits a stronger reduction in bandgap and can switch from a semiconductor to a metal at moderate tunneling currents, a behavior tied to its unique surface electronic structure.
Article Synopsis
- Gegen Qinlian decoction (GGQLD) is a traditional Chinese medicine used in clinical settings to manage inflammatory symptoms related to metabolic diseases and protect kidney function, with a specific focus on its effects against hyperuricemia (HUA).
- A study involving 30 HUA patients explored the impact of GGQLD on uric acid levels and inflammatory markers before and after a 4-week treatment, alongside further experimentation using animal models and kidney cells.
- Results indicated that GGQLD decreased inflammation and apoptosis in renal cells by lowering NLRP3 inflammasome expression, enhancing uric acid excretion, and demonstrating a multi-target approach to HUA treatment.
Article Synopsis
- PdSe is a new two-dimensional material known for its high carrier mobility and tunable band gap, making it suitable for various electronic and photonic applications.
- The study reports successful synthesis of few-layer, single-crystal PdSe flakes at a low temperature (300 °C) using low-pressure chemical vapor deposition (CVD) on sapphire substrates.
- Results show that the properties of PdSe, such as layer-dependent band gap shrinkage and strong transistor performance, hint at its potential for high-quality device fabrication.
Article Synopsis
- Cognitive impairments from brain irradiation significantly reduce patients' quality of life, and current preventive measures are ineffective.
- This study shows that electroacupuncture (EA), when applied right after irradiation in rats, can protect the blood-brain barrier and counteract early neuroinflammatory responses, aiding in cognitive function.
- The protective effects of EA on memory are linked to changes in synaptic structures rather than new neuron growth, highlighting its potential as a treatment for cognitive issues in brain tumor patients undergoing radiotherapy.
Purpose: Efficient tumor volume delineation by the combined use of PET/CT scanning is necessary for the proper treatment of non-small cell lung cancer (NSCLC). To understand the effect of variation in background intensity on PET-based gross tumor volume (GTV) delineation, we determined the background standard uptake values (SUVs) in normal lung, aorta (blood pool), and liver tissues and determined GTVs using different methods.
Methods: Thirty-seven previously untreated patients with pathologically confirmed NSCLC underwent PET/CT scanning with (18)F-fluorodeoxyglucose ((18)F-FDG).

Objective: To observe the therapeutic effect of local antibiotic injection into the female prostate on female urethral syndrome (FUS), and search for an effective treatment for this disease.
Methods: This study included 163 FUS patients treated in the out-patient department between July 2009 and December 2010. According to the visiting order, the patients were randomly assigned to Groups A (n = 58), B (n = 55) and C (n = 50).
[Relationship between gene polymorphism of CYP2E1, CYP1A1, IL-4 and medicamentosa-like dermatitis induced by trichloroethylene].

Objective: To investigate the relationship between gene polymorphism of CYP2E1, CYP1A1, IL-4 and susceptibility of medicamentosa-like dermatitis induced by trichloroethylene (TCE).
Methods: 35 patients with medicamentosa-like dermatitis induced by TCE were chosen as the patient group, and 35 healthy workers as control group. The real-time quantitative polymerase chain reaction (PCR) with TaqMan minor groove binding (MGB) probes was used to test single nucleotide polymorphisms (SNP) of CYP2E1, CYP1A1 and IL-4 in the patients with medicamentosa-like dermatitis as well as in the control.
