The carbon and nitrogen (N) metabolism of rice under different mid-stage N compensation timings is unclear. Two Japonica super rice cultivars were examined under four N compensation timings (N1-N3: N compensation at mid-tillering, panicle initiation, and spikelet differentiation. N0: no N compensation) and CK with no N application.

  • Pegpesen® is a new once-weekly treatment for growth hormone deficiency (GHD) in children, designed to offer an alternative to daily human growth hormone therapy.
  • A phase 3 clinical trial involving 391 children showed that Pegpesen® had a growth velocity similar to daily rhGH, indicating it is non-inferior.
  • The safety and adherence profiles for Pegpesen® were comparable to daily rhGH, suggesting it could be a beneficial option due to lower dosage requirements.

The KRAS G12C mutations, as crucial biomarkers, are closely associated with non-small cell lung cancer. Here, a novel label-free electrochemical biosensor with synergistic signal amplification of photocell energy transfer-reversible addition fragmentation chain transfer (PET-RAFT) and ring-opening polymerization (ROP) was developed for the first time for sensitive detection of KRAS G12C mutations. Specifically, hairpin DNA (hDNA), which act as biomolecular probe, was self-assembled on Au electrode surface by Au-S bond.

  • - This phase 3 study evaluated a 6-month prolonged release formulation of triptorelin for treating central precocious puberty (CPP) in Chinese children, focusing on its efficacy, safety, and pharmacokinetics.
  • - In an open-label trial involving 66 children (93.9% girls), the treatment successfully suppressed luteinizing hormone (LH) levels in all participants by month 6, with 98.5% maintaining this suppression at month 12, alongside other positive hormone and development outcomes.

Methylmalonic acidemia (MMA) is the most common inborn organic acidemia, presenting multisystemic complications. Uric acid may have neurotoxic or neuroprotective effects due to its antioxidant or pro-inflammatory properties; however, its role in MMA brain injury remains unclear. We examined the correlation between the serum uric acid levels and brain imaging features of MMA.

Structure determines the properties. However, whether electronic structure determines geometry or geometry determines electronic structure seems a philosophical question in a chicken and egg situation, which remains unclear. In this work, by applying density functional theory (DFT) and DMRG(4,4)-CASSCF methods, theoretical investigation suggested that the dual antiaromaticity in cyclo[2]carbons with even should be attributed to the electron correlation effect, instead of decreased geometric symmetry, which actually exists in all cyclo[2]carbon molecules and does not point out the essence.

To investigate the fine starch structure characteristics and formation mechanism of high-quality appearance soft rice, two high-quality and low-quality soft rice varieties (HA-SR and LA-SR, respectively) were selected. Differences in appearance quality, fine starch structure, and activity of key enzymes involved in starch synthesis during the grain-filling stage were compared. The results showed that compared with LA-SR, HA-SR were less chalky, more transparent, had larger starch grains, a lower content of shorter chains (DP 6-24), a higher content of longer chains (DP ≥ 25), lower relative crystallinity, fewer ordered structures, more amorphous structures and larger thicknesses of semi-crystalline lamellae.

  • Rational nitrogen application can boost rice yield and eating quality, but too much can harm both and pollute the environment.
  • Reduced nitrogen application with dense planting (RNDP) is beneficial for maintaining rice yield and improving nitrogen efficiency, yet its effects on grain quality were previously unclear.
  • A two-year study found that while reduced nitrogen alone decreased yield, RNDP maintained yield and significantly improved rice eating quality due to changes in starch structure and properties.

Background: Transient neonatal diabetes mellitus (TNDM) is a rare form of diabetes mellitus that usually presents within the first 6 mo of life. Patients often enter remission within several months, although relapse can occur later in life. Mutations in the gene, which encodes the sulfonylurea receptor 1 of the ATP-sensitive potassium channel in pancreatic beta cells, are associated with TNDM and permanent neonatal diabetes.

  • The production of ammonia from nitrogen sources is complex due to competitive adsorption and transfer processes, making catalyst design challenging.
  • The study takes inspiration from natural nitrogenases and designs a two-component metal-sulfur-carbon (M-S-C) catalyst using sulfur-doped carbon-supported ruthenium (Ru) for nitrate reduction to ammonia.
  • The catalyst exhibits impressive ammonia yield and efficiency over extended periods, highlighting the importance of Ru single atoms and their coordination with sulfur in enhancing reaction pathways, contributing to a deeper understanding of catalyst mechanisms for nitrogen reduction.
