Individualized Prediction of Overall Survival Time for Patients with Primary Intramedullary Spinal Cord Astrocytoma: A Population-Based Study.

Background: The incidence rate of primary intramedullary spinal cord astrocytoma (IMSCA) is approximately 0.047 per 100,000 individuals per year, making it the second most common type of intramedullary spinal cord tumor. Due to its rarity, there is a scarcity of related research, and prognostic factors remain unclear.

Copper assisted sequence-specific chemical protein conjugation at a single backbone amide.

Direct, site-specific methods of protein functionalization are highly desirable for biotechnology. However, such methods are challenging due to the difficulty of chemically differentiating a single site within a large protein. Herein, we propose "metal binding targeting" strategy and develop a Copper Assisted Sequence-specific conjugation Tag (CAST) method to achieve rapid (second order rate 8.

New Information: The species (Cramer, [1779]) is the first record of the genus from China.

Constructing an unprecedented {Mn} matryoshka doll with a [Mn(CO)] inorganic core and magnetocaloric effect.

An unprecedented inner [Mn(CO)] inorganic core and [Mn] metal-organic periphery compose a high-nuclearity homometallic single-valent {Mn} molecular aggregate with a [Mn] ⊂ [Mn] ⊂ [Mn] ⊂ [Mn] matryoshka doll-like skeleton that displays a significant magnetocaloric effect (MCE).

Complete mitochondrial genome of the Endangered long-armed scarab (Coleoptera: Euchiridae).

The long-armed scarab is an endangered large insect in southwestern China and neighboring countries. Herein, we present the first complete mitochondrial genome of . The 16,899 bp long circular genome consists of 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes, and a non-coding control region.

OsbHLH6 interacts with OsSPX4 and regulates the phosphate starvation response in rice.

Low soil phosphorus (P) availability is a major limitation for crop production. The molecular mechanisms underlying plant responses and adaptation to phosphate (Pi) deficiency are unclear. OsbHLH6 (hereafter bHLH6), an uncharacterized rice (Oryza sativa) Pi starvation response gene encoding a basic helix-loop-helix protein, was identified by yeast two-hybrid screening using the phosphate response repressor OsSPX4 (hereafter SPX4) as bait.

Strong genetic differentiation among populations of (Coleoptera: Euchiridae) in its native area sheds lights on species conservation.

The long-armed scarab () is an endangered large insect in southwestern China and neighboring countries; however, limited information is available regarding its population genetics, hindering conservation efforts. Therefore, we investigated the population genetic structure and evolutionary history of in southwestern China. Twenty-five haplotypes were obtained from 47 specimens across five populations.

CASEIN KINASE2-Dependent Phosphorylation of PHOSPHATE2 Fine-tunes Phosphate Homeostasis in Rice.

Plants have evolved complex physiological and biochemical mechanisms to adapt to a heterogeneous soil phosphorus environment. PHOSPHATE2 (PHO2) is a phosphate (Pi) starvation-signaling regulator involved in maintaining Pi homeostasis in plants. Arabidopsis () PHO2 targets PHOSPHATE TRANSPORTER1 (PHT1) and PHO1 for degradation, whereas rice () PHO2 is thought to mediate PHOSPHATE TRANSPORTER TRAFFIC FACILITATOR1 degradation.

PROTEIN PHOSPHATASE95 Regulates Phosphate Homeostasis by Affecting Phosphate Transporter Trafficking in Rice.

Phosphate (Pi) uptake in plants depends on plasma membrane (PM)-localized phosphate transporters (PTs). OsCK2 phosphorylates PTs and inhibits their trafficking from the endoplasmic reticulum (ER) to the PM in rice (), but how PTs are dephosphorylated is unknown. We demonstrate that the protein phosphatase type 2C (PP2C) protein phosphatase OsPP95 interacts with OsPT2 and OsPT8 and dephosphorylates OsPT8 at Ser-517.

OsSPL3, an SBP-Domain Protein, Regulates Crown Root Development in Rice.

The major root system of cereals consists of crown roots (or adventitious roots), which are important for anchoring plants in the soil and for water and nutrient uptake. However, the molecular basis of crown root formation is largely unknown. Here, we isolated a rice () mutant with fewer crown roots, named ().

Rice SPX6 negatively regulates the phosphate starvation response through suppression of the transcription factor PHR2.

Phosphorus (P) is an essential macronutrient for plant growth and development, but the molecular mechanism determining how plants sense external inorganic phosphate (Pi) levels and reprogram transcriptional and adaptive responses is incompletely understood. In this study, we investigated the function of OsSPX6 (hereafter SPX6), an uncharacterized member of SPX domain (SYG1, Pho81 and XPR1)-containing proteins in rice, using reverse genetics and biochemical approaches. Transgenic plants overexpressing SPX6 exhibited decreased Pi concentrations and suppression of phosphate starvation-induced (PSI) genes.

[Study of Paints and Drawing Techniques of Fine Brushwork Yunlong Ripples Painting in Qing Dynasty].

In order to study the paints and techniques of decorative patterns of dragon among clouds and water waves, the materials based on a Qing Dynasty meticulous painting were measured by three-dimensional video microscopy, Raman microscopy and energy dispersive X-ray fluorescence spectroscopy. The results showed that the green clothes was firstly colored by Paris green, the decorative patterns of dragon among clouds and water waves were then painted by hematite, the edge was delineated by brass powder at last. The dark yellow area within the decorative patterns was presented due to the interaction of green and red paints.

[Research Progress of Raman Spectroscopy on Dyestuff Identification of Ancient Relics and Artifacts].

As the birthplace of Silk Road, China has a long dyeing history. The valuable information about the production time, the source of dyeing material, dyeing process and preservation status were existed in organic dyestuff deriving from cultural relics and artifacts. However, because of the low contents, complex compositions and easily degraded of dyestuff, it is always a challenging task to identify the dyestuff in relics analyzing field.

Aqueous compatible boron nitride nanosheets for high-performance hydrogels.

Hexagonal boron nitride nanosheets (BNNSs) possess ultimate thermal and chemical stabilities and mechanical strengths. However, the unmodified BNNSs are hydrophobic and insoluble in water, which hinders their use in many technological areas requiring aqueous compatibility. In this work, h-BN was treated with molten citric acid to produce aqueous dispersible boron nitride sheets (ca-BNNSs).

[Raman microspectroscopic analysis of polychrome wooden artifact from the Astana tomb of the tang dynasty, Xinjiang, China].

The Turpan District is characterized by a typical dry climate, so that many organic relics have been well preserved. A piece of wooden artifact with 9 colors was unearthed from Astana graveyard which is rich in cultural connotations. In the present paper, Raman microscopy was employed for in-situ, nondestructive analysis of pigments that remained on this artifact, and many mineral pigments (gypsum, red lead, carbon black, haematite, atacamite) and vegetable dyes (gamboges and indigo) were identified.
