The Evolution of Curve Patterns in Adolescent Idiopathic Scoliosis during Chêneau Brace Treatment.

Study Design/setting: This retrospective study analyzed bracing outcomes in AIS patients, focusing on curve pattern changes and brace efficacy.

Objective: To analyze the effectiveness of the Chêneau brace across different curve patterns and to evaluate the tendencies in curve evolution during treatment.

Summary Of Background Data: Adolescent idiopathic scoliosis (AIS) presents diverse curve patterns, each responding differently to bracing.

ZmmiR169q/ZmNF-YA8 is a module that homeostatically regulates primary root growth and salt tolerance in maize.

In response to salt stress, plants alter the expression of manifold gene networks, enabling them to survive and thrive in the face of adversity. As a result, the growth and development of plant roots could be drastically altered, with significant inhibition of the growth of root meristematic zones. Although it is known that root growth is primarily regulated by auxins and cytokinins, the molecular regulatory mechanism by which salt stress stunts root meristems remains obscure.

Molecular Characterization and Efficacy Evaluation of Transgenic Maize Harboring -- for Insect Resistance and Herbicide Tolerance.

Insect infestation and weed interference have a seriously negative impact on the growth, yield, and grain quality of maize. In this study, transgenic maize plants harboring three exogenous genes, , , and , that were constructed into a single T-DNA were developed for protection against insects and weeds. The transgene integration sites on the chromosomes in two transgenic maize events, CVC-1 and CVC-2, were determined using whole genome sequencing and specific PCR detection.

Scoliosis Secondary to Neurofibromatosis Type I Combined With Moyamoya Syndrome: A Case Report.

Case: A 13-year-old girl presenting with scoliosis accompanied by type I neurofibromatosis (NF1) underwent deformity correction surgery. On the second postoperative day, she had sudden-onset acute cerebral infarctions and was diagnosed with moyamoya syndrome. After neurological conservative treatment, at the sixth month after surgery, her symptoms and signs were significantly improved and the daily life was not affected by herself.

A novel fluoroscopy-based robot system for pedicle screw fixation surgery.

Background: Robot-assisted pedicle screw insertion has gained popularity in the spinal surgery field. Due to high cost, these spinal robots are not extensively applied in clinical surgeries. Developing an effective robot system with low cost and high clinical acceptability is one of the future trends.

HS1 Is Involved in Hygromycin Resistance Through Facilitating Hygromycin Phosphotransferase Transportation From Cytosol to Chloroplast.

The transportation of proteins encoded by nuclear genes from plant cytosol to chloroplast is essential for chloroplast functions. Proteins that have a chloroplast transit peptide (cTP) are imported into chloroplasts via translocases on the outer and inner chloroplast envelope. How proteins lacking transit sequence are imported into chloroplast remains largely unknown.

Overexpression of the maize γ-tocopherol methyltransferase gene (ZmTMT) increases α-tocopherol content in transgenic Arabidopsis and maize seeds.

The vitamin E family includes tocopherols and tocotrienols, which are essential lipid-soluble antioxidants necessary for human and livestock health. The seeds of many plant species, including maize, have high gamma (γ)-tocopherol but low alpha (α)-tocopherol contents; however, α-tocopherol is the most effective antioxidant. Therefore, it is necessary to optimize the tocopherol composition in plants.

Interactions of Oryza sativa OsCONTINUOUS VASCULAR RING-LIKE 1 (OsCOLE1) and OsCOLE1-INTERACTING PROTEIN reveal a novel intracellular auxin transport mechanism.

Little is known about the transport mechanism of intracellular auxin. Here, we report two vacuole-localized proteins, Oryza sativa OsCONTINUOUS VASCULAR RING-LIKE 1 (OsCOLE1) and OsCOLE1-INTERACTING PROTEIN (OsCLIP), that regulate intracellular auxin transport and homoeostasis. Overexpression of OsCOLE1 markedly increased the internode length and auxin content of the stem base, whereas these parameters were decreased in RNA interference (RNAi) plants.

ZmSOC1, a MADS-box transcription factor from Zea mays, promotes flowering in Arabidopsis.

Zea mays is an economically important crop, but its molecular mechanism of flowering remains largely uncharacterized. The gene, SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1), integrates multiple flowering signals to regulate floral transition in Arabidopsis. In this study, ZmSOC1 was isolated from Zea mays.

Construction of a genomewide RNAi mutant library in rice.

Long hairpin RNA (hpRNA) transgenes are a powerful tool for gene function studies in plants, but a genomewide RNAi mutant library using hpRNA transgenes has not been reported for plants. Here, we report the construction of a hpRNA library for the genomewide identification of gene function in rice using an improved rolling circle amplification-mediated hpRNA (RMHR) method. Transformation of rice with the library resulted in thousands of transgenic lines containing hpRNAs targeting genes of various function.

GmTMT2a from soybean elevates the α-tocopherol content in corn and Arabidopsis.

Tocochromanol, or vitamin E, plays a crucial role in human and animal nutrition and is synthesized only by photosynthetic organisms. γ-Tocopherol methyltransferase (γ-TMT), one of the key enzymes in the tocopherol biosynthetic pathway in plants, converts γ, δ-tocopherols into α-, β-tocopherols. Tocopherol content was investigated in 15 soybean cultivars and GmTMT2 was isolated from five varieties based on tocopherol content.

Functional analysis of BnMAR element in transgenic tobacco plants.

Scaffold/matrix attachment regions (S/MARs) are defined as genomic DNA sequences, located at the physical boundaries of chromatin loops. Previous reports suggest that S/MARs elements may increase and stabilize the expression of transgene. In this study, DNA sequence with MAR characteristics has been isolated from B.

A simple artificial microRNA vector based on ath-miR169d precursor from Arabidopsis.

Artificial microRNA (amiRNA) is becoming a powerful tool for silencing genes in plants, and several amiRNA vectors have recently been developed based on the natural precursor structures of ath-miR159a, ath-miR164b, ath-miR172a, ath-miR319a and osa-miR528. In this study we generated a simple amiRNA vector (pAmiR169d) based on the structure of Arabidopsis miR169d precursor (pre-miR169d). Two unique restriction sites were created inside the stem region of pre-miR169d, which allows for the artificial miRNA sequences to be cloned as either ~80 bp synthetic oligonucleotides or PCR products.

Rolling circle amplification-mediated hairpin RNA (RMHR) library construction in plants.

Long hairpin RNA (lhRNA) construct-induced gene silencing facilitates the study of gene function in plants and animals, but constructing multiple lhRNA vectors using traditional approaches is both time-consuming and costly. Also, most of the existing approaches are based on sequence-specific cloning of individual sequences, and are therefore not suitable for preparing hpRNA libraries from a pool of mixed target sequences. Here we describe a rolling-circle amplification (RCA)-mediated hpRNA (RMHR) construction system suitable for generating libraries of lhRNA constructs from any gene of interest or pool of genes.
