Although the prevalence number was low compared to other head traumas, its morbidity and mortality number were higher. Brain abscess formation is one of the many PBI complications. Due to direct inoculation of foreign body and its debris, PBI commonly leads an infection process. However, the infection process is supposed to be overcome by administering broad-spectrum antibiotics prophylactically. This case presented an inevitable brain abscess despite of the adequate antibiotics administration. Conclusion Despite adequate antibiotics has been administered, cerebellar abscess after penetrating brain injury is still found challenging to manage. Therefore, holistic-multidisciplinary approaches are needed.Background Prevalence of self-reported methamphetamine use has remained relatively stable over the past decade; however, deaths and seizures involving methamphetamine have been increasing. Research is needed to determine if select subgroups in the US are at increased risk for use. Methods We examined data from individuals ages ≥12 from the 2015-2018 National Survey on Drug Use and Health (n = 226,632), an annual nationally representative cross-sectional survey of non-institutionalized individuals in the US. Log-linear trends in past-year methamphetamine use were examined, stratified by demographic and drug use characteristics. Results Methamphetamine use increased in the US from 2015 to 2018, including among those reporting past-year use of ecstasy/MDMA (6.1 % to 10.8 % [p = .018], a 78.2 % increase), cocaine (8.4 % to 11.8 % [p = .013], a 40.1 % increase), and among those reporting past-year prescription opioid misuse (5.4 % to 8.0 % [p = .019], a 49.2 % increase). Increases were particularly pronounced among those reporting past-year use of heroin (22.5 % to 37.4 % [p = .032], a 66.2 % increase) and LSD (5.1 %-= to 10.3 % [p = .002], a 100.4 % increase). Small increases were also detected among heterosexuals (0.6 % to 0.7 % [p = .044], a 16.2 % increase), those with a high school diploma or less (1.0 % to 1.2 % [p = .020], a 22.0 % increase), and among those receiving government assistance (1.4 % to 1.8 % [p = .046], a 26.2 % increase). Conclusions Methamphetamine use is increasing among people who use other drugs with sharp increases among people who use heroin or LSD in particular, and this could have serious public health consequences. Results may signal that methamphetamine use may continue to increase in the general population.Analysis of post-mortem liver for toxicological reasons is a considerable option when blood is unavailable. The development of analytical methods for tissue specimens is not as straightforward as for biological fluids as tissue presents challenges to the analytical chemist. The present study reports the development of a UHPLC-MS/MS method for the detection and quantification of 84 drugs and pharmaceuticals in human liver. The selected target drugs include pharmaceutical drugs and drugs of abuse. Sample preparation was studied using QuEChERS and different ratios of solvent volume and sample mass. Best results were attained by homogenizing 1 g of liver with acetonitrile K2CO3 buffer (pH = 10), QuEChERS salts MgSO4/ NaCl (1st purification step) and PSA/ 150 mg MgSO4 (2nd purification step). The extracted sample was analysed on UHPLC-MS/MS in multiple reaction monitoring mode (MRM) on a reversed-phase (Acquity BEH C18) column. Elution was accomplished by gradient program of mobile phase A water, 0.1% formic acid and B methanol, 0.1% formic acid that lasted 17 min. RVX-208 in vitro The method was specific, without interferences from the complex matrix. Sensitivity was satisfactory with limit of detection (LOD) ranging from 0.01 ng/g to 4.94 ng/g. Validation study was based on the guidelines of international bodies and included evaluation of recovery, carry-over, matrix effect, accuracy, stability, and precision of the method. The method performed satisfactory in relation to established bioanalytical criteria and was therefore applied to the analysis of liver tissue obtained post-mortem from chronic drug abusers, offering unambiguous identification and quantitative determination of drugs in postmortem blood.Lipophilic antioxidant determination is of relevance in health and diseases. Several HPLC methods exists but rare are those including coenzyme Q10 with carotenoids, retinol and tocopherols. Here a single-step extraction was proposed for the detection of retinol, α and γ-tocopherols, lutein, zeaxanthin, trans-ß-carotene, α-carotene, ß-cryptoxanthin and lycopene as well as coenzyme Q10. A single HPLC column was used and UV-vis diode array detection was performed. Echinenone, alpha-tocopherol nicotinate and coenzyme Q4 were employed as internal standards. Intra-assay and inter-assay precision were respectively 1.4-7.9% and 2.2-15.8%. Accuracy was validated using SRM 968e. LOD (limit of detection) and LOQ (limit of quantification) obtained were sufficient for nutritional epidemiological study and routine clinical application.Background The combination of Panax ginseng and Angelica sinensis (CPA) has been used to treat stroke for one thousand years and demonstrated clinically to have satisfied effects. However, the underlying mechanism remains unknown. Purpose We investigate whether CPA has neuroprotective effects via suppressing Nod-like receptor protein 3 (NLRP3) inflammasome and microglial pyroptosis against ischemic injury in transient middle cerebral artery occlusion (MCAO) rats. Methods Male rats were divided randomly into sham operated, MCAO, MCC950 (NLRP3-specific inhibitor) and CPA groups. Neurological deficits, glucose uptake, infarct size, activation of NLRP3 inflammasomes, microglial pyroptosis and related signaling pathways were detected. BV-2 microglial cells subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) were used in in vitro experiments. Results Compared with sham rats, elevated level of proinflammatory interleukin-1β (IL-1β) in plasma, neurological function deficit, reduced glucose uptake in ipsilatsion.Background Cyperenoic acid, one of the main chemical constituents of the root of Croton crassifolius, exhibited potent anti-angiogenic property on the zebrafish embryo model with little cytotoxicity. Nevertheless, its anti-angiogenic mechanism and anti-tumor effect have not been investigated. Purpose To investigate the anti-angiogenic mechanisms of cyperenoic acid and evaluate it whether could exert anti-tumor effect by inhibiting angiogenesis. Study design Targeting vascular endothelial growth factor receptor-2 (VEGFR2) pathway to inhibit tumor angiogenesis is a significant strategy for cancer treatment. Initially, the anti-angiogenic effect of cyperenoic acid as well as the mechanisms of the action was studied using both in-vitro and in-vivo methodologies. Then, its anti-tumor effect through anti-angiogenesis by attenuating VEGFR2 signaling pathway was evaluated. Methods The in-vitro inhibitory effect of cyperenoic acid on the vascular endothelial growth factor (VEGF)-induced angiogenesis was evaluated using human umbilical vein endothelial cells (HUVECs) model.
