The influence of ultraviolet light irradiation on the pitting corrosion performance of a Zr_(2)Ni metallic glass was examined using electrochemical methods and immersion test in 0.05 mol/L Nacl *** the results of potentiostatic polarization,the pitting potential of the ultraviolet light-irradiated sample shifted positively with a value of~300 mV,revealing the enhanced pitting corrosion resistance of the *** corrosion morphology after the immersion test also demonstrated lower degree of corrosion damage and improved pitting resistance of the sample with ultraviolet light irradiation.X-ray photoelectron spectroscopy analysis revealed more zirconium enrichment in the passive film and no chloride ions adsorption for the samples with ultraviolet irradiation,accounting for the suppression of the pit generation and *** findings indicate that ultraviolet light irradiation improves the pitting corrosion resistance of the Zr-based metallic glasses,which are promising structural materials to be used in corrosion environments with high ultraviolet irradiation.

To investigate the surface damage of a material by He ions,a dispersion-strengthened W-1wt%Tic alloy was irradiated by 5-keV He ions at 773 K,973 K,and 1173 K up to an ion dose of 1.8×10^(21)He m−2,*** He bubble formation was observed under transmission electron microscopy at any temperature for He doses less than 1.5×10^(20)He m^(−2).When this dose was exceeded,He bubbles grew and void swelling increased with increasing irradiation ***,the growth of He bubbles and the void swelling became more pronounced with increasing irradiation *** to the published data on commercially available pure W,the formation of He bubbles was suppressed by Tic particles in the W-Tic alloy,especially at low doses.

cerebral ischemia is one of the leading causes of morbidity and mortality worldwide. Although stroke （a form of cerebral ischemia）-related costs are expected to reach 240.67 billion dollars by 2030, options for treatment against cerebral ischemia/stroke are limited. All therapies except anti-thrombolytics （i.e., tissue plasminogen activator） and hypothermia have failed to reduce neuronal injury, neurological deficits, and mortality rates following cerebral ischemia, which suggests that development of novel therapies again st stroke/cerebral ischemia are urgently needed. Here, we discuss the possible mechanism（s） underlying cerebral ischemia-induced brain injury, as well as current and future novel therapies （i.e., growth factors, nicotinamide adenine dinucleotide, melatonin, resveratrol, protein kinase c isozymes, pifithrin, hypothermia, fatty acids, sympathoplegic drugs, and stem cells） as it relates to cerebral ischemia.

Department of General IcU the First Affiliated Hospital of Zhengzhou University Zhengzhou 450052China.

To explore the clinical characteristics and related risk factors of intracerebral hemorrhage (IcH) lesions identified on susceptibility-weighted imaging (SWI) sequences in patients with recent subcortical small infarct (RSSI). The patients with lenticulostriate artery territory RSSI admitted to the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from January 2019 to December 2022 was retrospectively collected. Demographic information, past medical history, laboratory, and imaging data were collected. Observe the IcH lesions in patients on the brain SWI sequence and divide RSSI patients into the coexisting-IcH group (=37) and the non-IcH group (=324) according to whether they have IcH. At the same time, the hemorrhage-related imaging features coexisting such as cerebral microbleeds (cMBs), cerebral surface siderosis (cSS), and probable cerebral amyloid angiopathy (cAA). Multifactorial logistic regression model was used to analyze the associated factors of IcH lesions in RSSI patients. A total of 361 patients with RSSI in the lenticulostriate artery territory area were included. The mean age was (60±12) years, with 243 male patients (67.3%). Among them, 37 patients (10.2%) had coexisting IcH lesions, mainly presenting as strict deep type [29 cases (78.4%)], with others including strict lobar type [2 cases (5.4%)], infratentorial type [2 cases (5.4%)], and mixed type[ 4 cases (10.8%)]. 30 cases (8.3%) had concomitant strict lobar cMBs, 5 cases (1.4%) had cSS, and 23 cases (6.4%) met the Boston 2.0 criteria for probable cAA. Multivariate logistic regression model analysis revealed that the high-grade enlargement of perivascular spaces in the basal ganglia (HEPVS) (=3.356,95%:1.208-9.320,=0.020) were associated with the presence of IcH lesions. When the total cerebral small vessel disease (cSVD) burden score was used to represent other cSVD imaging markers for analysis, the cSVD total burden score (=2.319,95%:1.596-3.372,<0.001) was also
