An injury to a peripheral nerve in animals often leads signs of neuropathic pain including hyperalgesia heat, cold and mechanical stimuli. The role injured intact fibers was evaluated rats subjected an L5 spinal ligation-and-cut ('modified SNL lesion'). To assess the contribution afferents, dorsal rhizotomy performed immediately before, or 7 days after modified lesion. study adjacent nerves, L4 up-down method Dixon (Dixon WJ, Annu Rev Pharmacol Toxicol 1980;20:441-462) used measure paw...

An L5 spinal nerve ligation (SNL) in the rat leads to behavioral signs of mechanical hyperalgesia. Our recent finding that an dorsal root rhizotomy did not alter hyperalgesia following SNL suggests signals originating from proximal stump injured are essential. We postulate Wallerian degeneration fibers altered properties adjacent intact nociceptive afferents. To investigate role sensory versus motor fibers, five injury models were examined concurrently a blinded fashion. ganglionectomy...

Adjacent vertebral fracture (AVF) is a serious complication of percutaneous vertebroplasty (PVP) or kyphoplasty (PKP) for osteoporotic compression (OVCF). This study aimed to explore the incidence and risk factors AVF following PVP PKP in postmenopausal women. The was determined by spinal radiographic examinations. potential were identified univariate analysis, followed multivariate logistic regression analyses determine independent factors. In total, 674 women who treated with from December...

Denervation in man often results shiny, dry, thin skin. A previous study has shown that the epidermis of glabrous skin rat becomes approximately 40% thinner within 1 week following sciatic nerve transection, but which fiber type or types influence epidermal thickness is unknown. In this study, we compared effects on selective sensory, motor, and sympathetic denervation. Protein gene product 9.5 calcitonin gene-related peptide immunocytochemical staining were used to determine extent...

Determining mineral prospecting targets is crucial for prediction and evaluation. In this study, an evaluation index system solid exploration metallogenic target assessment was established using the Analytic Hierarchy Process (AHP) Naoniushan area (China). Furthermore, integrated model combining geology–aerogeophysics–geochemistry developed copper, lead, zinc, silver, other polymetallic deposits. The information content of each in reasonably assigned, central southern parts Daxinganling were...

To reduce the energy consumption and total annual cost (TAC) of conventional extractive distillation (CED) process, this study focuses on process intensification by combination salt-based DESs entrainers, partial heat-integrated intermediate reboilers for 2-propanol + water separation process. The vapor-liquid equilibrium experiments showed that (ChCl:U:CaCl2)1:2:0.36 is most promising among all entrainers investigated. Based thermodynamic study, conceptual design CED was created to examine...

During shield tunneling, interactions with existing structures, such as pile foundations and bridges, are frequently encountered, leading to a growing implementation of cutting techniques. This study utilizes metro tunnel project crossing under ring expressway bridge in city Northeast China develop refined three-dimensional finite difference method (FDM) model. The 3D FDM model investigates the mechanical responses structure due through residual foundations. proposed numerical is validated...

Progress in the exploration of uranium deposits Qinling region is impacted by a number factors, including extensive forest distribution, large-scale terrain segmentation, and hidden ore bodies. Airborne gamma-ray spectrometry measurement direct method for exploration, with data containing rich mineralization information. In addition to surface information, such measurements also contain some information on deep mineralization. Based geological characteristics specific area region,...

Multi-stage axial compressors play a crucial role in aerospace propulsion systems, as their exit flow field characteristics directly impact engine performance and stability. This study conducted numerical simulations on the first 3.5 stages of NASA 74A transonic multi-stage compressor to analyze under different typical operating conditions. The research primarily investigated airflow deflection angle, radial velocity distribution, variation patterns. Additionally, effects inlet angle...

This study determined the content of metal elements (As, Cd, Cr, Hg, Pb) in 9 edible mushrooms using ICP-MS, and evaluated harm long-term consumption to human health. The results showed that concentrations decreased order Cd > As Cr Pb Hg mushrooms. As, Pb, were 22.95%, 8.20%, 1.64%, 3.28% higher, respectively, than maximum standards China, whereas did not exceed limit. detection rate Morchella esculenta (L.) Pers (M. esculenta), Agaricus blazei Murill (A. blazei) relatively high. single...

We have demonstrated previously that acute nerve compression produces ischemia/reperfusion injury in rat sciatic nerve. In this study, we evaluated the effects of deferoxamine, an antioxidant, on recovery from after compression. The nerves male Sprague-Dawley rats, 370 to 430 g, were subjected 24 hours with Silastic tubing. control group received intravenous saline solution at time decompression. therapeutic deferoxamine (50 mg per kilogram) removal Nerve tissues within and distal site...

This study aimed to evaluate the difference and consistency between single-photon emission computed tomography-computed tomography (SPECT-CT) MRI in diagnosing osteoporotic vertebral compression fractures (OVCFs) identifying active lesions.All 46 patients underwent SPECT-CT examinations. The pain body sites were determined using both during percutaneous kyphoplasty (PKP). differences before after treatment assessed visual analog scale scores evaluated a paired t-test. Furthermore, conformity...
