Broadband detection technology is crucial in the fields of astronomy and environmental surveying. Two dimensional (2D) materials have emerged as promising candidates for next-generation broadband photodetectors with the characteristics of high integration, multi-dimensional sensing, and low power consumption. Among these, 2D tellurium (Te) is particularly noteworthy due to its excellent mobility, tunable bandgap, and air stability.

Article Synopsis
  • Insecticide resistance is complicated, and a new study focuses on how the chemosensory system contributes to this resistance, specifically looking at a gene called RpCSP6 and its interaction with the insecticide deltamethrin.
  • The study shows that RpCSP6 is present in various tissues and developmental stages and can be induced by deltamethrin; when this gene is knocked down, insects become more vulnerable to the insecticide.
  • Key findings include the identification of seven important residues that interact with deltamethrin, which can help in developing more effective insecticides that target insect chemosensory proteins (CSPs).

Background: Tamoxifen (TAM) is recommended as the first-line strategy for men with estrogen receptor (ER)-positive early breast cancer who are candidates for adjuvant endocrine therapy in ASCO guideline. Our study aims to analyze the cost-effectiveness of receiving adjuvant endocrine therapy with TAM compared to no TAM, and to assess the cost-effectiveness of using TAM with high adherence over low adherence for ER-positive early male breast cancer in the USA.

Methods: Two Markov models comprising three mutually exclusive health states were constructed: (1) the first Markov model compared the cost-effectiveness of adding TAM with not using TAM (TAM versus Not-TAM); (2) the second model compared the cost-effectiveness of receiving TAM with high adherence and low adherence (High-adherence-TAM versus Low-adherence-TAM).

Article Synopsis
  • CRF-like diuretic hormone receptors (CRF/DHR) are GPCRs that help regulate osmotic balance in insects and could be potential targets for new insecticides.
  • The study focused on two DHR genes from the aphid species Rhopalosiphum padi, revealing that RpDHR1 expression rises after starvation and drops after RNA interference.
  • Findings indicate that RpDHR1 plays a crucial role in helping aphids cope with starvation and dehydration, suggesting its potential as a target for developing novel insecticides.

Articular cartilage injury is a prevalent clinical condition resulting from trauma, tumors, infection, osteoarthritis, and other factors. The intrinsic lack of blood vessels, nerves, and lymphatic vessels within cartilage tissue severely limits its self-regenerative capacity after injury. Current treatment options, such as conservative drug therapy and joint replacement, have inherent limitations.

Many aphid species exhibit both cyclical parthenogenesis (CP) and the obligate parthenogenesis (OP) life history, which are genetically determined. In CP aphid lineages, the parthenogenetic individuals can switch from asexual to sexual reproduction quickly in response to environmental factors such as changes in photoperiod and temperature. However, the OP aphid lineages do not undergo sexual reproduction under any conditions.
