Neurosurgeons represent 0.5% of all physicians and currently face a high burden of disease. Physician-scientists are essential to advance the mission of National Academies of Science (NAS) and National Institutes of Health (NIH) through discovery and bench to bedside translation. We investigated trends in NIH neurosurgeon-scientist funding over time as an indicator of physician-scientist workforce training.

We used NIH Research Portfolio Online Reporting Tools (RePORTER) to extractgrants to neurosurgery departments and neurosurgeons from 1993 to 2017. Manual extraction of each individual grant awardee was conducted.

After adjusting for U.S. inflation (base year 1993), NIH funding to neurosurgery departments increased yearly (P < 0.00001). However, neurosurgeon-scientists received significantly less NIH funding compared to scientists (including basic scientists and research only neurosurgeons) (P = 0.09). The ratio of neurosurgeon-scientists to scientists receiving grants was significantly reduced (P  that were awarded NIH grants compared to scientists demonstrates a declining trend. This observed shift is disproportionate in the number of NIH grants awarded to senior level compared to early-career neurosurgeon-scientists, with more funding allocated towards neurosurgical-oncology-related grants.Testis-specific gene antigen 10 (TSGA10) plays an important role in spermatogenesis. However, the exact TSGA10 role and its relationship with the autophagy pathway in the process of spermatids differentiation/maturation is still not clear. Therefore, the present study evaluates the role of TSGA10 gene in the spermatid differentiation/maturation through its effect on autophagy and explores possible underlying pathway(s). Sperm samples from patients with teratospermia were collected. The mRNA and protein level of TSGA10 in these samples were assessed by real-time PCR and western blotting. Using the ingenuity pathway analysis (IPA) software, the gene network and interactions of TSGA10 involved in sperm maturation and autophagy were investigated. Based on these analyses, the expression levels of identified genes in patient's samples and healthy controls were further evaluated. Moreover, using flow cytometry analysis, the levels of reactive oxygen species (ROS( production in teratospermic sperm samples were evaluated. The results showed that the expression levels of TSGA10 mRNA and protein decreased significantly in the teratospermic patients compared to controls (P less then 0.05).

Also, the levels of ROS production in teratospermic sperm samples were shown to be significantly higher compared to those in normal sperms (P less then 0.05). Our findings provide new evidence that simultaneous decrease in TSGA10 and autophagy beside the increased level of ROS production in sperm cells might be associated with the abnormalities in the spermatids differentiation/maturation and the formation of sperms with abnormal morphology.Cerebellar transcranial direct current stimulation (c-tDCS) enhances motor skill acquisition and motor learning in young and old adults. Since the cerebellum is involved in the pathophysiology of Parkinson's disease (PD), c-tDCS may represent an intervention with potential to improve motor learning in PD. The primary purpose was to determine the influence of long-term application of c-tDCS on motor learning in PD. The secondary purpose was to examine the influence of long-term application of c-tDCS on transfer of motor learning in PD. The study was a randomized, double-blind, SHAM-controlled, between-subjects design. Twenty-one participants with PD were allocated to either a tDCS group or a SHAM stimulation group. Participants completed 9 practice sessions over a 2-week period that involved extensive practice of an isometric pinch grip task (PGT) and a rapid arm movement task (AMT). These practice tasks were performed over a 25-min period concurrent with either anodal c-tDCS or SHAM stimulation. A set of transfer tasks that included clinical rating scales, manual dexterity tests, and lower extremity assessments were quantified in Test sessions at Baseline, 1, 14, and 28 days after the end of practice (EOP). There were no significant differences between the c-tDCS and SHAM groups as indicated by performance changes in the practice and transfer tasks from Baseline to the 3 EOP Tests. The findings indicate that long-term application of c-tDCS does not improve motor learning or transfer of motor learning to a greater extent than practice alone in PD.Toll-like receptor (TLR) agonists are emerging as promising vaccine adjuvants and immunomodulators in poultry against many diseases. Infectious bursa disease (IBD) still remains as a major threat to poultry industry. Improving the vaccine mediated immune response would help in better protection against IBD virus infection. Adjuvant potential of TLR3 agonist, Polinosinic polycytidylic acid (Poly IC) with different IBD vaccines has been analyzed in chicken in the present study. Intermediate, intermediate plus IBD vaccine, bursaplex vaccine and their respective poly IC combinations were used for immunization of chicken. IBD specific antibody titers, bursa to body weight ratio, body weight gain and bursal lesion scores were evaluated at weekly interval in different immunization groups. Fold changes in cytokines IL-1β and IFN-γ mRNA expression levels in spleen were also analyzed in different groups. Intermediate plus IBD vaccine induced significantly (P ≤ 0.05) higher IBD specific antibody response at 35 days of age than other groups with comparatively lower body weight gain and moderate bursal lesion score. Poly IC co-administration with intermediate IBD vaccine and bursaplex vaccine improved the IBD specific antibody titers, better body weight gain and moderately less bursal lesion score. However, Poly IC combination with intermediate plus IBD vaccine did not improve the specific immune response. IL-1β levels were up-regulated in intermediate plus and bursaplex group, whereas IFN-γ m RNA expression levels were upregulated in intermediate IBD with Poly IC group. In conclusion, poly IC co-administration with intermediate IBD and bursaplex vaccine was beneficial and improved the specific immune response with least immunosuppression and bursal damage.
