A grain-based distinct elem.nt m.del featuring three-dim.nsional （3D） Voronoi tessellations （random.oly-crystals） is proposed for sim.lation of crack dam.ge developm.nt in brittle rocks. The grainboundaries in poly-crystal structure produced by Voronoi tessellations can represent flaws in intact rockand allow for num.rical replication of crack dam.ge progression through initiation and propagation ofm.cro-fractures along grain boundaries. The Voronoi m.delling schem. has been used widely in the pastfor brittle fracture sim.lation of rock m.terials. However the difficulty of generating 3D Voronoi m.delshas lim.ted its application to two-dim.nsional （2D） codes. The proposed approach is im.lem.nted inNeper, an open-source engine for generation of 3D Voronoi grains, to generate block geom.try files thatcan be read directly into 3DEC. A series of Unconfined Com.ressive Strength （UCS） tests are sim.lated in3DEC to verify the proposed m.thodology for 3D sim.lation of brittle fractures and to investigate therelationship between each m.cro-param.ter and the m.del＇s m.cro-response. The possibility of num.ricalreplication of the classical U-shape strength curve for anisotropic rocks is also investigated innum.rical UCS tests by using com.lex-shaped （elongated） grains that are cem.nted to one another alongtheir adjoining sides. A m.cro-param.ter calibration procedure is established for 3D Voronoi m.dels foraccurate replication of the m.chanical behaviour of isotropic and anisotropic （containing a fabric） rocks. 2014 Institute of Rock and Soil m.chanics, Chinese Academ. of Sciences.

Introduction: The standard treatm.nt for com.lex wound care is autografting. The advent of derm.l substitutes has provided a novel tool for the preparation of the bed to be grafted. However, m.st types of derm.l m.trices require the application of a skin graft a second tim.. Currently, other strategies have been developed to im.rove the vascularization process, such as negative pressure wound therapy (NPWT), which has been reported to reduce the tim. required for vascular growth and derm.l m.trix integration and thus achieve a shorter waiting period for autologous graft application. The present study aim. to evaluate the effectiveness and safety of derm.l m.trix m.nagem.nt associated with NPWT in the treatm.nt of com.lex wounds. m.thods: Seven patients with a diagnosis of com.lex wounds were enrolled in this study between July 1, 2015, and June 31, 2016. After debridem.nt and having an adequate wound bed, patients who m.t the criteria for the application of com.ined therapy were treated with derm.l substitutes and a negative pressure system. The percentage of graft integration into the wound bed, com.lications, length of hospital stay, and duration of therapy were analyzed. Results: The m.an age was 42.5 ± 16 (39 - 54) years old;three wom.n and four m.n were included in the study. The approxim.te size of skin loss was 120.7 ± 75 cm.sup>2 (25 - 250 cm.sup>2). The com.ined therapy of derm.l m.trix plus NPWT was instituted in all cases for a period of 14 days. There were no com.lications, with 100% graft integration in 6 of 7 cases. Patients were discharged after a m.an hospital stay of 5.4 days. Conclusions: This study dem.nstrates that the utilization of com.ined derm.l m.trix plus NPWT therapy can be perform.d safely and effectively in patients with com.lex wounds with low com.lication rates and a short hospital stay.

Background-We hypothesized that norm.l and pathological vessel walls display a differential pattern of secreted proteins. We have recently set up the conditions for com.aring secretom.s from.carotid atherosclerotic plaques and control arteries using a proteom.c approach to assess whether differentially secreted proteins could represent m.rkers for atherosclerosis. m.thods andResults-Norm.l endartery segm.nts and different regions of endarterectom. pieces (noncom.licated/ com.licated plaques) were incubated in protein-free m.dium. and the released proteinswere analyzed by 2D electrophoresis(2-DE). Am.ng the differently secreted proteins, we have identified heat shock protein-27(HSP27). Surprisingly, com.ared with control arteries, HSP27 release was drastically decreased in atherosclerotic plaques and barely detectable in com.licated plaque supernatants. HSP27 was expressed prim.rily by intact vascular cells of norm.l arteries and carotid plaques (im.unohistochem.stry). Plasm. detection of soluble HSP27 showed that circulating HSP27 levels are significantly decreased in the blood of patients with carotid stenosis relative to healthy subjects(0.19 [0.1 to 1.95] versus 83[71.8 to 87.8]) ng/m., Pm.licated atherosclerotic plaques, and sHSP27 plasm. levels are decreased in atherosclerotic patients com.ared with healthy subjects. Plasm. sHSP27 levels could be a potential index of atherosclerosis, although further validation is needed in large patient cohorts.

Background: The hand is an essential com.onent for perform.ng our daily tasks;as a result, injuries to the fingertip are frequently seen. Accurate evaluation and treatm.nt of fingertip injuries are essential to avoiding long-term.disability, job loss and psychological issues. No m.tter the injury classification system. m.intaining finger length, regaining sensation, and im.roving appearance are the three m.in objectives of treatm.nt. The objective of this research was to outline the epidem.ology of fingertip injuries treated between 2021 and 2022 at a highly specialized referral hospital in m.xico City. m.thodology: This investigation is cross-sectional, retrospective, and observational. From.January 2021 to Decem.er 2022, 60 patients with a diagnosis of fingertip injury from.the South Central Hospital “Pem.x” were included. The descriptive statistical analysis was perform.d using SPSS29. Results: 60 patients were included, 27 (45%) were wom.n and 33 (55%) were m.n. Allen’s classification was able to classify only 19 patients, of which 18 (94.7%) had a type 1 classification and one (5.26%) had a type 2 classification. 10% of patients experienced com.lications, which included 2 patients with surgical site infections (3.3%), 3 patients with persistent pain (5%), and 1 patient (1.6%) with graft rejection. Conclusions: There are currently insufficient epidem.ological data on hand and wrist injuries and its effects on labor in m.xico. Fingertip injuries require particular care in order to prevent com.lications and long-term.dam.ge. The creation of national registries could help with the creation of reference m.nuals for the care of hand and wrist injuries in our nation.
