Reconstruction of bone defects or fractures caused by ageing, trauma and tumour resection is still a great challenge in clinical treatment. Although autologous bone graft is considered as gold standard, the source of natural bone is limited. In recent years, regenerative therapy based on bioactive materials has been proposed for bone reconstruction. Specially, numerous studies have indicated that bioactive ceramics including silicate and phosphate bioceramics exhibit excellent osteoinductivity and osteoconductivity, further promote bone regeneration. In addition, magnesium (Mg) element, as an indispensable mineral element, plays a vital role in promoting bone mineralisation and formation. In this review, different types of Mg-containing bioceramics including Mg-containing calcium phosphate-based bioceramics (such as Mg-hydroxyapatite, Mg-biphasic calcium phosphate), Mg-containing calcium silicate-based bioceramics (such as Mg2SiO4, Ca2MgSi2O7and Mg-doped bioglass), Mg-based biocements, Mg-containing metal/polymer-bioceramic composites were systematacially summarised. Additionally, the fabrication technologies and their materiobiological effects were deeply discussed, Clinical applications and perspectives of magnesium-containing bioceramics for bone repair are highlighted. Overall, Mg-containing bioceramics are regarded as regenerative therapy with their optimised performance. Furthermore, more in-depth two-way researches on their performance and structure are essential to satisfy their clinical needs. © 2024, Chinese Medical Multimedia Press Co ltd. All rights reserved.

Inflammation and angiogenesis, the maj.r pathological changes of osteoarthritis (OA), are closely associated with j.int pain; however, pertinent signalling interactions within subchondral bone of osteoarthritic j.ints and potential contribution to the peripheral origin of OA pain remain to be elucidated. Herein we developed a unilateral anterior crossbite mouse model with osteoarthritic changes in the temporomandibular j.int. Microarray-based transcriptome analysis, besides quantitative real-time polymerase chain reaction, was performed to identify differentially expressed genes (DEGs). Overall, 182 DEGs (fold change ≥ 2, P l and unilateral anterior crossbite groups: 168 were upregulated and 14 were downregulated. On subj.cting significant DEGs to enrichment analyses, inflammation and angiogenesis were identified as the most affected. Inflammation-related DEGs were mainly enriched in T cell activation and differentiation and in the mammalian target of rapamycin/nuclear factor-κB/tumour necrosis factor signalling. Furthermore, angiogenesis-related DEGs were mainly enriched in the Gene Ontology terms angiogenesis regulation and vasculature development and in the KEGG pathways of phosphoinositide 3-kinase-protein kinase B/vascular endothelial growth factor/hypoxia-inducible factor 1 signalling. Protein– protein interaction analysis revealed a close interaction between inflammation-and angiogenesis-related DEGs, suggesting that phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta (Pi3kcd), cathelicidin antimicrobial peptide (Camp), C-X-C motif chemokine receptor 4 (Cxcr4), and MYB proto-oncogene transcription factor (Myb) play a central role in their interaction. To summarize, our findings reveal that in subchondral bone of osteoarthritic j.ints, signal interaction is interrelated between inflammation and angiogenesis and associated with the peripheral origin of OA pain; moreover, our data highlight potential t

Genotypes and Phenotypes of Uygur Children with Xeroderma Pigmentosum: A Case Study in Xinj.ang, China

International j.urnal of Dermatology and Venereology 2024年第3期7卷 144-149页

作者： Qiu Y. Wang W.-j. liang j.-Q. Yakeya B. Wang P. Zhang j.-Z. Kang X.-j. Department of Dermatology and Venereology People's Hospital of Xinjiang Uygur Autonomous Region Xinjiang Uygur Autonomous Region Urumqi 830001 China Xinj.ang Clinical Research Center for Dermatologic Diseases Xinjiang Uygur Autonomous Region Urumqi 830001 China Xinj.ang Key laboratory of Dermatology Research (Xj.S1707) Xinjiang Uygur Autonomous Region Urumqi 830001 China

Obj.ctive: Xeroderma pigmentosum (XP) is a rare autosomal recessive dermatosis caused by genetic defects of DNA repair. This study was performed to detect and analyze the genes of 2 Uygur patients with XP and their families and assess the patients' phenotypes, which may enrich the understanding of the genetic skin disorder spectrum in Xinj.ang area. Methods: We collected the clinical data from 2 patients with XP and peripheral blood samples from the patients and their family members. The patients' DNA was sequenced and detected by Sanger sequencing, and gene mutations were screened. Results: The proband in family 1 presented with brown maculae at the exposure site and squamous cell carcinoma secondary to a facial rash. The proband had a homozygous nucleotide variation of XPC c.2251-2A> G (A change from A to G in the penultimate position of the intron before the 2251 position in the coding region), which was a shear mutation. In this family, both parents were heterozygous, and no similar mutation detected in the sister. In family 2, the proband had scattered black brown spots and papules on the trunk and limbs. and his younger sister was also a patient. The proband and his younger sister had homonucleotide variation of XPA c.631C> T, which was nonsense mutation, resulting in the codon for Arg No.211 being changed into termination codon (***211X), thus terminating the peptide chain synthesis prematurely. All the normal individuals in the two families were heterozygotes, and homozygous mutations occurred in all the patients, which was consistent with the autosomal recessive inheritance. Conclusion: XP is rare in Uygur population. This study expanded the mutation spectrum of XP and provided a basis for early diagnosis, treatment, prognostic prediction, and prenatal genetic consultation. © 2022 Hospital for Skin Diseases (Institute of Dermatology), Chinese Academy of Medical Sciences, and Chinese Medical Association, published by Wolters Kluwer, Inc.

Wind power potential over northern South America using ERA5-land global reanalysis

ClEAN ENERGY 2024年第2期8卷 104-112页

The northernmost region of South America has great potential for wind energy production and is a strategic area for the energy transition. We analysed data from ERA5-land global reanalysis from 1980 to 2020 to determine the wind power potential in this area. Our aim was to identify areas with a high potential for wind energy that could be used to supply energy in case of drought in the region or increases in fuel prices. We compared data from 19 meteorological stations located in Colombia with ERA5-land reanalysis data to generate reliable information for the feasibility and operation of wind farms. According to our analysis, the Colombian Caribbean and Coastal Plain have monthly average wind speeds at 90 m ranging from 4.85 to 10.34 m/s and 3.79 to 6.62 m/s, respectively. Based on wind power density calculations, these regions have the highest wind power density in our study, with a monthly average of between 250 and 399 W/m2. The Caribbean Region had a 69% increase in wind power density from j.nuary to j.ly compared with the annual average. The wind power density in the plains increased from j.nuary to March, while the Mountain Region had higher anomalies from May to October. The Alta Guaj.ra and Paraguana Peninsula have great potential to generate wind energy due to their privileged geographical location. Although ERA5 offers valuable information about wind availability in time and space, it cannot represent the influence of local effects on wind patterns for the Mountain Region. Data from ERA5-land global reanalysis (1980-2020) are used to determine the wind power potential in the northernmost region of South America to identify areas with a high potential for wind energy, which could be used to supply energy in case of drought or increases in fuel prices.
