Phosphatidylinositol-3 kinase (PI3K) inhibitor and histone deacetylase (HDAC) inhibitor have been developed as potential anticancer drugs. However, the cytotoxicity of PI3K inhibitor or HDAC inhibitor alone is relatively weak. We recently developed a novel HDAC/PI3K dual inhibitor FK-A11 and confirmed its enhanced cytotoxicity when compared to that of PI3K inhibitor or HDAC inhibitor alone on several cancer cell lines. However, the in vivo antitumor activity of FK-A11 was insufficient. PD98059 We conducted high-throughput RNA interfering screening and identified gene LPIN1 which enhances the cytotoxicity of FK-A11. Downregulation of LPIN1 enhanced simultaneous inhibition of HDAC and PI3K by FK-A11 and enhanced the cytotoxicity of FK-A11. Propranolol, a beta-adrenoreceptor which is also a LPIN1 inhibitor, enhanced the in vitro and in vivo cytotoxicity and antitumor effect of FK-A11. These findings should help in the development of FK-A11 as a novel HDAC/PI3K dual inhibitor.Sleep disruption and deprivation are highly prevalent among parents of an infant. However, most postpartum sleep studies focus solely on mothers, and few studies have investigated whether sleep differs between first-time and experienced parents. The present study aimed to determine whether self-reported sleep duration and quality differ between first-time and experienced mothers and fathers during the postpartum period. A total of 111 parents (54 couples and three single mothers) of 6-month-old infants completed a 2-week sleep diary to evaluate measures of sleep duration, sleep continuity, and sleep quality. An analysis of covariance model was used to compare the sleep variables of first-time to experienced parents. Breastfeeding frequency, infant sleep location, depression, education, and work status were used as co-variables. First-time mothers reported a longer consecutive nocturnal sleep duration (mean [SEM] 297.34 [17.15] versus 246.01 [14.79] min, p less then .05), fewer nocturnal awakenings (mean [SEM] 1.57 [0.20] versus 2.12 [0.17], p less then .05), and rated their sleep quality higher (mean [SEM] score 7.07 [0.36] versus 5.97 [0.30], p less then .05) than experienced mothers, while total nocturnal sleep duration did not differ. There were no differences in subjective sleep measures between first-time and experienced fathers. The present study indicates that experienced mothers reported more fragmented sleep and perceived having worse sleep quality than first-time mothers, but that paternal sleep did not differ as a function of parental experience. These findings have clinical implications for healthcare professionals working with families of various configurations and sizes.Cigarette smoking is still the largest contributor to disease and death worldwide. Successful cessation is hindered by decreases in prefrontal glutamate concentrations and gray matter volume due to daily smoking. Because nondaily, intermittent smoking also contributes greatly to disease and death, understanding whether infrequent tobacco use is associated with reductions in prefrontal glutamate concentrations and gray matter volume may aid public health. Eighty-five young participants (41 nonsmokers, 24 intermittent smokers, 20 daily smokers, mean age ~23 years old), underwent 1 H-magnetic resonance spectroscopy of the medial prefrontal cortex, as well as structural magnetic resonance imaging (MRI) to determine whole-brain gray matter volume. Compared with nonsmokers, both daily and intermittent smokers exhibited lower concentrations of glutamate, creatine, N-acetylaspartate, and myo-inositol in the medial prefrontal cortex, and lower gray matter volume in the right inferior frontal gyrus; these measures of prefrontal metabolites and structure did not differ between daily and intermittent smokers. Finally, medial prefrontal metabolite concentrations and right inferior frontal gray matter volume were positively correlated, but these relationships were not influenced by smoking status. This study provides the first evidence that both daily and intermittent smoking are associated with low concentrations of glutamate, creatine, N-acetylaspartate, and myo-inositol and low gray matter volume in the prefrontal cortex. Future tobacco cessation efforts should not ignore potential deleterious effects of intermittent smoking by considering only daily smokers. Finally, because low glutamate concentrations hinder cessation, treatments that can normalize tonic levels of prefrontal glutamate, such as N-acetylcysteine, may help intermittent and daily smokers to quit.

Persistent back/and or leg pain is a common outcome after spinal surgery (otherwise known as failed back surgery syndrome [FBSS]). Studies have shown that spinal cord stimulation (SCS) at 10kHz provides effective analgesia in FBSS patients with both back and leg pain symptoms and in those with predominant back pain. This study is the first to evaluate the therapy in FBSS patients with predominant leg pain.

The safety and efficacy of 10kHz SCS was evaluated in an uncontrolled, open-label, prospective study of FBSS patients with predominant leg pain in the Netherlands. Follow-ups were performed at 1, 3, 6, and 12months post implantation.

Sixty out of 68 patients (88%) experienced sufficient pain relief during a stimulation trial. Of these, 58 proceeded to permanent implantation of a 10kHz SCS system. After 12months of treatment, 80% of patients experienced ≥50% reduction in baseline leg pain, and a similar proportion (76%) experienced ≥50% reduction in baseline back pain. At least two-thirds of patients were also leg pain and back pain remitters (visual analog scale [VAS] ≤2.5cm). The therapy was also associated with a general improvement in patients' quality of life, as measured by secondary outcomes including disability, perception of health improvement, mental well-being, and satisfaction. A positive impact on opioid consumption was also observed.

Consistent with previous findings, 10kHz SCS for the treatment of FBSS patients with predominant radicular symptoms is safe and effective and is associated with improved quality of life.
