OBJECTIVE This study evaluated the association between the diagnosis of sleep bruxism (SB), scored by way of polysomnographic (PSG) recordings, clinical conditions and sleep architecture. DESIGN A case-control study was conducted. All records from adults who had undergone polysomnography (PSG) recordings at a private medical outpatient clinic between January 2015 and December 2017 were reviewed. The sample included 58 bruxers (case group) and 58 non-bruxers (control group), identified based on the PSG recording and matched by sex and age. RESULTS Obese individuals had significantly lower chance (OR 0.18; 95 % CI 0.05-0.62; P = 0.005) of an SB diagnosis than individuals with normal BMI. Alcohol consumption significantly increased (OR 2.74; 95 % CI 1.11-6.78; P = 0.029) and OSA decreased the chances (OR 0.55; 95 % CI 0.23-1.30; P = 0.173) of an SB diagnosis. Bruxers had a significantly shorter wake time after sleep onset (WASO) (p = 0.002). As far as non-rapid eye movement (NREM) is concerned, the duration of stage N1 was statistically shorter (p = 0.034) and the duration of stage N3 was statistically longer (p = 0.001) in bruxers. Arousals (p = 0.013), arousals per hour (p = 0.009), respiratory disturbance index (RDI) values (p less then 0.0005) and the apnoea-hypopnea index (AHI) (p = 0.002) were all lower in bruxers than in non-bruxers. CONCLUSION The results of this study support a significant association between SB diagnosis, BMI and alcohol consumption. SB modified the sleep architecture as statistically significant differences were found between bruxers and non-bruxers for WASO, NREM stage N1 and N3, arousals, arousals per hour, RDI and AHI. BACKGROUND There has been growing interest in head impacts related to sports participation due to potential long- and short-term consequences of head injuries. Our purpose was to compare head impact magnitude and frequency between men's and women's intercollegiate soccer players based on head impact mechanism. METHODS 28 collegiate soccer players (16 women age = 19.94 (1.06) years, height = 163.75 (5.15) cm, mass = 61.21 (5.09) kg; 12 men age = 20.25 (1.14) years, height = 180.34 (6.03) cm, mass = 74.09 (9.32) kg) wore xPatch (X2 Biosystems, Seattle, WA) head impact sensors. Each practice and game was video recorded in order to confirm head impacts. The independent variable was impact mechanism (head to head, head to body (other than head), head to ground, ball to head, goal to head, and combination). Sensors collected linear and rotational accelerations and frequency of head impacts per 1000 athlete exposures. FINDINGS Men were more likely to sustain head impacts than women (IRR = 1.74, CI95 = 1.59-1.92). The highest head impact incidence rate for men was head to body (IR = 611.68, CI95 = 553.11-670.25) while the highest impact incidence rate for women was ball to head (IR = 302.29, CI95 = 270.93-333.64). The interaction between sex and mechanism was significant for rotational accelerations (F4, 1720 = 3.757, P = .005, ω2 = 0.013) but not for linear accelerations (F4,1720 = 0.680, P = .606, ω2  less then  0.001, 1 - β = 0.223). INTERPRETATION To reduce the frequency of head impacts in men, perhaps rules governing player to player contact should be more strictly enforced as these data confirm frequent player-to-head contact during soccer practices and games. Prevention efforts for women should be focused on limiting the amount of purposeful heading (planned contact between the head and ball) occurring during play especially since these impacts had higher magnitudes compared to men. The pathways for peripheral-to-central immune communication (P → C I-comm) following sterile lung injury (SLI) are unknown. SLI evokes systemic and central inflammation, which alters central respiratory control and viscerosensory transmission in the nucleus tractus solitarii (nTS). These functional changes coincide with increased interleukin-1 beta (IL-1β) in the area postrema, a sensory circumventricular organ that connects P → C I-comm to brainstem circuits that control homeostasis. We hypothesize that IL-1β and its downstream transcriptional target, cyclooxygenase-2 (COX-2), mediate P → C I-comm in the nTS. In a rodent model of SLI induced by intratracheal bleomycin (Bleo), the sigh frequency and duration of post-sigh apnea increased in Bleo- compared to saline- treated rats one week after injury. This SLI-dependent change in respiratory control occurred concurrently with augmented IL-1β and COX-2 immunoreactivity (IR) in the funiculus separans (FS), a barrier between the AP and the brainstem. At this barrier, increases in IL-1β and COX-2 IR were confined to processes that stained for glial fibrillary acidic protein (GFAP) and that projected basolaterally to the nTS. Further, FS radial-glia did not express TNF-α or IL-6 following SLI. To test our hypothesis, we blocked central COX-1/2 activity by intracerebroventricular (ICV) infusion of Indomethacin (Ind). Continuous ICV Ind treatment prevented Bleo-dependent increases in GFAP + and IL-1β + IR, and restored characteristics of sighs that reset the rhythm. These data indicate that changes in sighs following SLI depend partially on activation of a central COX-dependent P → C I-comm via radial-glia of the FS. Glioblastoma is a kind of malignant tumour and originates from the central nervous system. In the last century, some researchers and clinician have noticed that the psychosocial and neurocognitive functioning of patients with malignant gliomas can be impaired.  https://www.selleckchem.com/products/dl-alanine.html  Many clinical studies have demonstrated that part of patients, adults or children, diagnosed with glioblastoma will suffer from cognitive deficiency during their clinical course, especially in long-term survivors. Many nanoparticles (NPs) can inhibit the biological functions of tumours by modulating tumour-associated inflammation, which provokes angiogenesis and tumour growth. As one of the best antiviral nanoparticles (AVNPs), AVNP2 is the 2nd generation of AVNP2 that have been conjugated to graphite-graphene for improving physiochemical performance and reducing toxicity. AVNP2 inactivates viruses, such as the H1N1 and H5N1influenza viruses and even the SARS coronavirus, while it inhibits bacteria, such as MRSA and E. coli. As antimicrobials, nanoparticles are considered to be one of the vectors for the administration of therapeutic compounds.
