The invention belongs to the technical field of biological medicines, and relates to a pharmaceutical composition for treating cancer, in particular to an anti-tumor pharmaceutical composition with a synergistic effect and application thereof. The pharmaceutical composition reduces the dosage of single drug through the synergistic effect between drugs, and overcomes the strong toxic effect of the drug on cells. Solid tumor cell apoptosis is induced by increasing intracellular reactive oxygen species levels. The composition consists of arsenic trioxide and cobalt salt. The molar ratio of the arsenic trioxide to the cobalt salt is 1:1-1:10, preferably 1:2-1: 5. The cobalt salt is selected from cobalt acetate, cobalt chloride, cobalt phosphate, cobalt silicate, cobalt succinate, cobalt fumarate and cobalt sulfate. The pharmaceutical composition is used for synergistically inhibiting the growth of tumor cells and promoting the apoptosis of the tumor cells.

Research in industrial workers and professionals exposed to formaldehyde suggests that occupational exposure to this important chemical is associated with increased risk for myeloid leukemia. The significance, however, of these observations for occupational and environmental health is uncertain because of inconsistencies among epidemiologic studies and lack of a demonstrated mechanism through which formaldehyde can cause leukemia. Cytogenetic damage is one potential leukemogenic mechanism, but there are few studies of formaldehyde-exposed humans. Some experimental data suggest that epigenetic changes in myeloid cells could also be involved. We plan to study 40 workers exposed to high levels of formaldehyde and 40 unexposed controls to examine the hypothesis that formaldehyde is associated with these changes. To determine formaldehyde exposure, we will incorporate a number of methods, including questionnaires to determine potential past exposure and on-site monitoring to determine current average and peak intensities of exposure. We will then examine differences in aneuploidy and structural abnormalities in myeloid progenitor cells cultured from peripheral blood. We will specifically look for differences in genes associated with myeloid leukemia such as monosomy 7 and trisomy 8 using interphase and Octochrome FISH. We will also determine whether aberrant methylation in progenitor cells, specifically hypermethylation of genes associated with myeloid leukemia, is higher in those exposed to formaldehyde. This study will substantially contribute to our understanding of the leukemogenic potential of formaldehyde, which has important public health and regulatory implications.
ETHNOPHARMACOLOGICAL RELEVANCE: Fraxinus excelsior L. (FE), commonly known as the ash, belongs to the Oleaceae family and has shown several pharmacological and biological properties, such as antioxidant, immunomodulatory, neuroprotective, and anti-inflammatory effects. It has also attracted the most attention toward neuroinflammation. Moreover, FE bark and leaves have been used to treat neurological disorders, aging, neuropathic pain, urinary complaints, and articular pain in traditional and ethnomedicine. Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder resulting from the involvement of amyloid-beta, metal-induced oxidative stress, and neuroinflammation.
AIM OF THE STUDY: The objective of the current study was to assess the neuroprotective effects of hydromethanolic extract from FE bark in an AlCl3-induced rat model of AD.
MATERIALS AND METHODS: The maceration process was utilized to prepare the hydromethanolic extract of FE bark, and characterized by LC-MS/MS. To assess the anti-AD effects of the FE extract, rats were categorized into five different groups, AlCl3; normal control; FE-treated groups at 50, 100, and 200 mg/kg. Passive avoidance learning test, Y-maze, open field, and elevated plus maze behavioral tests were evaluated on days 7 and 14 to analyze the cognitive impairments. Zymography analysis, biochemical tests, and histopathological changes were also followed in different groups.
RESULTS: LC-MS/MS analysis indicated the presence of coumarins, including isofraxidin7-O-diglucoside in the methanolic extract of FE as a new isofraxidin derivative in this genus. FE significantly improved memory and cognitive function, maintained weight, prevented neuronal damages, and preserved the hippocampus's histological features, as demonstrated by behavioral tests and histopathological analysis. FE increased anti-inflammatory MMP-2 activity, whereas it decreased that of inflammatory MMP-9. Moreover, FE increased plasma antioxidant capacity by enhancing CAT and GSH while decreasing nitrite levels in the serum of treated groups. In comparison between the treated groups, the rats that received high doses of the FE extract (200 mg/kg) showed the highest therapeutic effect.
CONCLUSION: FE rich in coumarins could be an effective anti-AD adjunct agent, passing through antioxidant and anti-inflammatory pathways. These results encourage further studies for the development of this extract as a promising agent in preventing, managing, or treating AD and related diseases.
BACKGROUND: Relation between the emergence of ITP and the presence of TNFα 308G/A polymorphism in the involved individuals has been studied by previous researchers in different ethnicity, but a definite result was not gained. So, this meta-analysis was performed to find an absolute answer to the question whether TNF-α-308G/A polymorphism is a susceptibility factor for ITP or not?
METHODS: Electronic databases including PubMed, Google scholar, and Science Direct were searched and case control studies compatible to the defined inclusion criteria were selected; their references were also evaluated manually. Pooled OR with 95 % confidence intervals (CIs) as a strength of association between TNF-α-308G/A polymorphism and risk of ITP were calculated using a random-effect model. Funnel plot and Egger's linear regression test were conducted to examine the risk of publication bias.
RESULTS: Totally, 16 eligible articles were found involving 1470 ITP cases and 2324 healthy controls. The Meta-results revealed that TNFα 308G/A polymorphism is associated with increased risk of ITP under the genetic models of recessive (OR: 1.54, 95 % CI: 1.03-2.29), dominant (OR: 2.29, 95 % CI: 1.44-3.64), and the heterozygote (OR: 2.46, 95 % CI:1.49-4.6). Subgroup analysis suggested a remarkable role for this SNP as a risk factor in the Caucasian ethnicity and the chronic subtype.
CONCLUSION: TNFα 308G/A polymorphism can be an ITP susceptibility factor in the Caucasian population and the chronic subtype. Although more studies in large scale are needed for clinical decision but this finding can be used in the clinical trials to prevent the ITP consequences in the involved individuals.

There are many subjects who are conscious of ameliorating the symptoms within about one hour for the eyes and nose, thus demonstrating the quick efficacy of the tested samples.  <P>COPYRIGHT: (C)2004,JPO
Endothelial cell (EC) barrier disruption and inflammation are the pathological hallmarks of vascular disorders and acute infectious diseases and related conditions, including the coronavirus disease 2019 (COVID-19) and sepsis. Ubiquitination plays a critical role in regulating the stability, intracellular trafficking, and enzymatic activity of proteins and is reversed by deubiquitinating enzymes (DUBs). The role of DUBs in endothelial biology is largely unknown. In this study, we report that USP40, a poorly characterized DUB, prevents EC barrier disruption through reductions in the activation of RhoA and phosphorylation of myosin light chain (MLC) and cofilin. Furthermore, USP40 reduces EC inflammation through the attenuation of NF-ĸB activation, ICAM1 expression, and leukocyte-EC adhesion. We further show that USP40 activity and expression are reduced in response to endotoxin challenge. Global depletion of USP40 and EC-targeted USP40 depletion in mice exacerbated experimental lung injury, whereas lentiviral gene transfer of USP40 protected against endotoxin-induced lung injury. Using an unbiased approach, we discovered that the protective effect of USP40 occurs through the targeting of heat shock protein 90β (HSP90β) for its deubiquitination and inactivation. Together, these data reveal a critical protective role of USP40 in vascular injury, identifying a unique mechanistic pathway that profoundly impacts endothelial function via DUBs.
The XL TDR is indicated for reconstruction of the disc following discectomy in skeletally mature subjects with symptomatic degenerative disc disease (DDD) of the lumbar spine at one level from L1-L5. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history radiographic studies.
BACKGROUND: The addition of pembrolizumab (pembro) to neoadjuvant chemotherapy (NAC) is standard of care for the treatment of early triple-negative breast cancer (TNBC) after KEYNOTE-522 trial demonstrated improved pathologic complete response (pCR) rates with the combination. However, the optimal treatment strategy for TNBC remains uncertain as questions persist about which patients benefit from pembro and the best treatment schedule and regimen. We identified real-world clinical characteristics and treatment variables associated with response to NAC plus pembro.
METHODS: Patients with early TNBC treated with NAC plus pembro between February 2020 and September 2023 were identified. Univariate and multivariate analysis was performed using logistic regression to identify factors associated with pCR. Cox proportional hazard prediction models were used to identify predictors of invasive disease-free survival and overall survival in this cohort.
RESULTS: A pCR was achieved in 75 (63.6%) of 118 patients. Age at diagnosis (P = .04), Ki-67 (P = .004), duration from start of pembro to surgery (P = .006) and NAC to surgery (P = .01), number of cycles of pembro (P = .04) and NAC (P = .02), and completion of at least 8 cycles of pembro (P = .015) and NAC (P = .015) were each significantly associated with pCR in univariate analysis. In multivariate analysis, patients younger than 55 years at time of diagnosis (vs age > 55 years) and those completing at least 8 cycles of pembro remained predictive of pCR (OR's 2.50, 2.49, P = .035 and .037, respectively).
CONCLUSIONS: In this real-world analysis of patients with TNBC treated with NAC plus pembro, younger age and the completion of at least 8 cycles of pembrolizumab were associated with pCR.

PURPOSE:To obtain a water-soluble algin fiber containing an antibiotic substance included in the fiber, having antibacterial property and useful as medical materials such as gauze, bandage and patch by incorporating an antibiotic substance in a water-soluble algin fiber. CONSTITUTION:An aqueous dope containing an antibiotic substance and a water- soluble alginic acid salt (e.g. sodium alginate) is extruded into a large amount of a hydrophilic organic solvent (e.g. acetone) to effect the substitution of water in the aqueous dope with the solvent and obtain the objective fiber. The concentration of the water-soluble algin in the aqueous dope is 3-20wt.%. Since an antibiotic substance used as an ointment or injection is contained in a water-soluble algin fiber, the fiber has antibacterial activity, prevents the bacterial injury such as infectious diseases in the case of using the fiber as a coating material for scald and wound and keeps the activity of the antibiotic substance over a long period.
This is a randomized single-center parallel study with a control group design. A blinded block randomization in groups of four was performed in equal parts toward the treatment (TPC) or the control (regular standard-of-care) group using randomization.com. Group assignment was kept in a closed envelope which was opened by the participant at the end of the baseline visit. Therefore both, the movement disorder specialist as well as the physiotherapist, were blinded to the randomization result for the baseline assessment up to the beginning of the first physiotherapy training session.

Therapeutic effects were evaluated at follow-up visits after 12 weeks (first visit, short-term effect) and after 26 weeks (second visit, long-term effect) comparing standard-of care with the TPC. Clinical evaluation is stated in detail below. Primary outcome assessment of this study was the change between baseline and follow-up assessment in treatment to control group in the spastic paraplegia rating scale (SPRS) score as a validated measure of disease severity (see Reference). Secondary outcome assessment was the change in walking distance in the Three-Minute-Walking test (3MW). Further exploratory outcome assessments were evaluated as effect sizes as specified below.
This study addresses a crucial necessity in the field of noninvasive liver fibrosis diagnosis by introducing the concept of continuous shear wave elastography (C-SWE), utilizing an external vibration source and color Doppler imaging. However, an application of C-SWE to assess liver elasticity, a deep region within the human body, arises an issue of signal instability in the obtained data. To tackle this challenge, this work proposes a method involving the acquisition of multiple frames of datasets, which are subsequently compressed. Furthermore, the proposed frame-to-frame equalization method compensates discrepancies in the initial phase that might exist among multiple-frame datasets, thereby significantly enhancing signal stability. The experimental validation of this approach encompasses both phantom tests and in vivo experiments. In the phantom tests, the proposed technique is validated through a comparison with the established shear wave elastography (SWE) technique. The results demonstrate a remarkable agreement, with an error in shear wave velocity of less than 4.2%. Additionally, the efficacy of the proposed method is confirmed through in vivo tests. As a result, the stabilization of observed shear waves using the frame-to-frame equalization technique exhibits promising potential for accurately assessing human liver elasticity. These findings collectively underscore the viability of C-SWE as a potential diagnostic instrument for liver fibrosis.
Despite advances in treatment, a significant proportion of patients with chronic lymphocytic leukemia (CLL) will relapse with drug-resistant disease. The imipridones, ONC-201 and ONC-212, are effective against a range of different cancers, including acute myeloid leukemia (AML) and tumors of the brain, breast, and prostate. These drugs induce cell death through activation of the mitochondrial protease, caseinolytic protease (CIpP), and the unfolded protein response (UPR). Here we demonstrate that the novel imipridone analog, TR-57, has efficacy as a single agent and synergises with venetoclax against CLL cells under in vitro conditions that mimic the tumor microenvironment. Changes in protein expression suggest TR-57 activates the UPR, inhibits the AKT and ERK1/2 pathways and induces pro-apoptotic changes in the expression of proteins of the BCL-2 family. The study suggests that TR-57, as a single agent and in combination with venetoclax, may represent an effective treatment option for CLL.

Glaucoma is a complex neurodegenerative disease characterized by optic nerve damage and visual field loss, and remains a leading cause of irreversible blindness. Elevated intraocular pressure (IOP) is a critical risk factor that requires effective management. Emerging research underscores dual roles of bioactive lipid mediators in both IOP regulation, and the modulation of neurodegeneration and neuroinflammation in glaucoma. Bioactive lipids, encompassing eicosanoids, specialized pro-resolving mediators (SPMs), sphingolipids, and endocannabinoids, have emerged as crucial players in these processes, orchestrating inflammation and diverse effects on aqueous humor dynamics and tissue remodeling. Perturbations in these lipid mediators contribute to retinal ganglion cell loss, vascular dysfunction, oxidative stress, and neuroinflammation. Glaucoma management primarily targets IOP reduction via pharmacological agents and surgical interventions, with prostaglandin analogues at the forefront. Intriguingly, additional lipid mediators offer promise in attenuating inflammation and providing neuroprotection. Here we explore these pathways to shed light on their intricate roles, and to unveil novel therapeutic avenues for glaucoma management.

Long QT Syndrome (LQTS) is a genetic heart disorder that can induce cardiac arrhythmias. The most prevalent subtype, LQT1, stems from rare variants in the KCNQ1 gene. Utilizing induced pluripotent stem cells (iPSCs) enables detailed cellular studies and personalized medicine approaches for this life-threatening condition. We generated two LQT1 iPSC lines with single nucleotide nonsense mutations, c.1031 C > T and c.1121 T > A in KCNQ1. Both lines exhibited typical iPSC morphology, expressed high levels of pluripotent markers, maintained normal karyotype, and possessed the capability to differentiate into three germ layers. These cell lines serve as important tools for investigating the biological mechanisms underlying LQT1 due to mutations in the KCNQ1 gene.
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a grievous disease that adversely affects human health and life. β-elemene is a type of sesquiterpenoid extracted from Curcuma wenyujin (Zingiberaceae) and displays effects on suppressing tumor growth. However, the regulatory impact of β-elemene in COPD development is not reported.
OBJECTIVE: This study explored the functioning of β-elemene in the progression of COPD.
MATERIAL AND METHODS: The cell survival rate was confirmed through Cell Counting Kit-8 (CCK-8) assay. The cell apoptosis was evaluated through flow cytometry. The protein expressions were examined through western blot. The levels of malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen species (ROS) were examined through the corresponding commercial kits. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-1β were inspected through Enzyme-Linked Immunosorbent Assay (ELISA).
RESULTS: The study demonstrated that β-elemene exaggerated cell viability and reduced cell apoptosis in BEAS-2B human bronchial epithelial cell line stimulated by cigarette smoke extract (CSE). Oxidative stress was heightened after 5% CSE induction, but this impact was counteracted by β-elemene treatment. In addition, enhancive inflammation induced by cigarette smoke was attenuated by β-elemene treatment. Finally, our results indicated that the triggered the phosphatidylinositol 3-kinase-protein kinase B-mechanistic target of rapamycin (PI3K/AKT/mTOR) pathway mediated by cigarette smoke was refrained by β-elemene treatment.
CONCLUSION: It was concluded that β-elemene reduced cigarette smoke-triggered inflammation, apoptosis, and oxidative stress in human bronchial epithelial cell line, and refrained PI3K/AKT/mTOR signaling pathway. This study proposed that β-elemene could act as a hopeful drug for the treatment of COPD.
