Bin He, Wen Wei, Ji Liu, Yundan Xu, Gang Zhao
Curcumin is an anticancer compound that exerts anti-proliferative and apoptotic effects via multiple molecular targets. The purpose of the present study was to investigate the anticancer effects of curcumin in combination with 5-fluorouracil plus cisplatin (FP) on the MGC-803 human gastric cancer cell line. Following treatment with curcumin and/or FP for 24, 48 and 72 h, cell viability, cell cycle progression and the apoptosis rate were evaluated using an MTT assay, flow cytometry and dual acridine orange/ethidium bromide staining, respectively...

The present review aimed to assess the safety and efficacy of thalidomide and lenalidomide, two immunomodulatory drugs with anti-angiogenic properties, in women with recurrent ovarian, fallopian tube, and primary peritoneal cancer. A systematic review of the literature was conducted whereby Medline and the Cochrane Central Register of Controlled Trials were searched using terms associated with thalidomide, lenalidomide, and recurrent ovarian, fallopian tube and primary peritoneal cancer. Published English language case reports, trials and studies that described the safety and efficacy of thalidomide or lenalidomide alone, or in combination with other drugs were reviewed...

The increasing incidence of obesity and diabetes due to changes in diet, earlier menarche, delayed menopause, late marriage, and declining birth rate have resulted in an increase in the number of endometrial cancer cases over the last few decades. Although surgical therapy is sufficient for early endometrial cancer, there is no effective therapy for patients with advanced and recurrent endometrial cancer. The oncogenic mechanism of endometrial cancer involves microsatellite instability (MSI) caused by dysfunction of DNA mismatch repair genes in 30% of patients...

The repurposing of drugs is becoming increasingly attractive as it avoids the lengthy process and cost implications associated with bringing a novel drug to market. Itraconazole is a broad-spectrum anti-fungal agent. An emerging body of in vivo, in vitro and clinical evidence have confirmed that it also possesses antineoplastic activities and has a synergistic action when combined with other chemotherapeutic agents. It acts via several mechanisms to prevent tumour growth, including inhibition of the Hedgehog pathway, prevention of angiogenesis, decreased endothelial cell proliferation, cell cycle arrest and induction of auto-phagocytosis...

Recent studies suggest that allicin may play a role in chronic kidney disease (CKD), reducing hypertension and oxidative stress and improving renal dysfunction. In the present study, CKD was induced by 5/6 nephrectomy and the animals were divided into four treatment groups as follows: control (C), CKD, CKD+allicin (40 mg/kg pathway oral) (CKDA), and CKD+Losartan (20 mg/kg) (CKDL). After CKD induction, the rats developed hypertension from week 3 to the end of the study. This was associated with increased creatinine and blood urea nitrogen (BUN) levels in serum, increased albuminuria, increased urinary excretion of N-acetyl-β-d-glucosaminidase (NAG), increased nephrin expression, and incrased histological alterations in the cortex...

Increasing evidence accumulates that metabolites of the dissociative anesthetic ketamine contribute considerably to the biological effects of this drug and could be developed as next generation antidepressants, especially for acute treatment of patients with therapy-refractory major depression. Analytical methods for the simultaneous determination of the plethora of hydroxylated, dehydrogenated and/or demethylated compounds formed after administration of ketamine hydrochloride are a prerequisite for future clinical investigations and a deeper understanding of the individual role of the isomers of these metabolites...

Desirable nanosystem that could not only deliver drugs safely and effectively into tumor sites, but also be expected to serve as photosensitizer to realize the photodynamic therapeutic function, would be of great significance in the synergistic cancer therapy. To perform this task, a multifunctional nanosystem has been developed for markedly enhanced cancer therapeutic efficacy by loading chemotherapy agent (doxorubicin hydrochloride, DOX) and photosensitive drug chlorin e6 (Ce6) into the channels of mesoporous zirconium dioxide (ZrO2) layer which coats on Nd(3+)-doped upconversion nanoparticles (UCNPs)...

Diabetes is an irreversible condition characterized by elevated blood glucose levels. Currently, there are no predictive biomarkers for this disease and the existing ones such as hemoglobin A1c and fasting blood glucose are used only when diabetes symptoms are noticed. The objective of this work was first to explore the potential of leucine and isoleucine amino acids as diabetes type 2 biomarkers using their Raman spectroscopic signatures. Secondly, we wanted to explore whether Raman spectroscopy can be applied in comparative efficacy studies between commercially available anti-diabetic drug pioglitazone and the locally used anti-diabetic herbal extract Momordica spinosa (Gilg...

Cell envelopes of many bacteria consist of two membranes studded with efflux transporters. Such organization protects bacteria from the environment and gives rise to multidrug resistance. We report a kinetic model that accurately describes the permeation properties of this system. The model predicts complex non-linear patterns of drug uptake complete with a bifurcation, which recapitulate the known experimental anomalies. We introduce two kinetic parameters, the efflux and barrier constants, which replace those of Michaelis and Menten for trans-envelope transport...

Targeting DNA hypermethylation, using nucleoside analogs, is an efficient approach to reprogram cancer cell epigenome leading to reduced proliferation, increased differentiation, recognition by the immune system, and ultimately cancer cell death. DNA methyltransferase inhibitors have been approved for the treatment of myelodysplastic syndromes, chronic myelomonocytic leukemia, and acute myelogenous leukemia. To improve clinical efficacy and overcome mechanisms of drug resistance, a second generation of DNA methyltransferase inhibitors has been designed and is currently in clinical trials...

OBJECTIVE: We compared the tolerability and efficacy of intranasal sub-dissociative ketamine to intranasal fentanyl for analgesia of children with acute traumatic pain and investigated the feasibility of a larger non-inferiority trial that could investigate the potential opioid sparing effects of intranasal ketamine. METHODS: This randomized controlled trial compared intranasal ketamine 1 mg/kg to intranasal fentanyl 1.5 μg/kg in children 4-17 years old with acute pain from suspected, isolated extremity fractures presenting to an urban level II pediatric trauma center from December 2015 to November 2016...

We evaluated whether the current bioequivalence limit is adequate to ensure safety and efficacy of rivaroxaban in patients under total hip arthroplasty and total knee arthroplasty based on its model informed benefit/risk profile. Clinical data from a total of 7145 patients from 3 phase 2 and 4 phase 3 clinical trials were included in the current model-based exposure-response analysis. The relationships between rivaroxaban exposure measurements (ie, minimum or trough, maximum, average concentration, and area under the concentration-time curve [AUC] at steady state) and clinical outcomes (ie, the probabilities of major bleeding [MB] and venous thromboembolism [VTE]) were modeled using NONMEM 7...

Depression is a common psychiatric disorder and a leading cause of disability world-wide. Traditional Chinese medicine is one of the commonly used complementary and alternative medicine therapies for depression. Clinical trials have been carried out to assess the efficacy and safety of Chinese herbal medicine currently. The exploration of herbal mechanisms of action used for the treatment of depression has also received great attention. This study is performed to summarize the frequently used formulae, patent drugs and single herbs in treating depression, review the literatures of clinical trials in treating depressive disorders, and to list the possible mechanisms involved during the treatment...

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a progressive, enduring, and often irreversible adverse effect of many antineoplastic agents, among which sensory abnormities are common and the most suffering issues. The pathogenesis of CIPN has not been completely understood, and strategies for CIPN prevention and treatment are still open problems for medicine. OBJECTIVES: The objective of this paper is to review the mechanism-based therapies against sensory abnormities in CIPN...
