Aims Heart failure with preserved ejection fraction (HFpEF) is one of the major diagnoses in dyspnoeic subjects, and H2 FPEF score enables robust differentiation of HFpEF. Given ventilatory abnormalities prevail in subjects with HFpEF, the associations between H2 FPEF score and pulmonary function remain to be elucidated. selleck chemicals Methods and results Subjects who presented with exertional dyspnoea and had left ventricular ejection fraction of >50% were eligible for this study. Total lung capacity, forced expiratory volume in the 1 s, and forced vital capacity (FVC) were obtained by pulmonary function tests. Pulmonary artery systolic pressure (PASP), the ratio of early ventricular filling flow velocity to the septal mitral annulus tissue velocity (E/e'), and left ventricular mass (LVM) were measured by echocardiogram. Among a total of 5849 participants (65.6 ± 6.4 years, 54% men), 2453 (41.9%) had low H2 FPEF score (0 ~ 1) and 160 (2.7%) had high H2 FPEF score,6~9 respectively. Subjects with high H2 FPEF score were older and had higher proportion of restrictive and obstructive defect, more morbidities, poorer renal function, lower haemoglobin, higher LVM, E/e' ratio, and PASP. During a mean follow-up duration of 30.0 ± 20.5 months, the H2 FPEF score was significantly associated with mortality [hazard ratio and 95% confidence intervals, 1.063(1.010-1.18)], independent of sex, haemoglobin, renal function, LVM, and comorbidities. Conclusions Either obstructive or restrictive ventilation defects prevail in subjects with high H2 FPEF score, indicating chronic obstructive pulmonary disease (COPD) is commonly associated with HFpEF. In addition, H2 FPEF score was correlated with long-term survival in dyspnoeic subjects with or without concomitant diseases of HFpEF and COPD.Autism has long been considered a predominantly male condition. It is increasingly understood, however, that autistic females are under-recognized. This may reflect gender stereotyping, whereby symptoms are missed in females, because it is assumed that autism is mainly a male condition. Also, some autistic girls and women may go unrecognized because there is a "female autism phenotype" (i.e., a female-typical autism presentation), which does not fit current, male-centric views of autism. Potential biases shown by educators, in their role as gatekeepers for an autism assessment, may represent a barrier to the recognition of autism in females. We used vignettes describing autistic children to test (a) whether gender stereotyping occurs, whereby educators rate males as more likely to be autistic, compared to females with identical symptoms; (b) whether recognition is affected by sex/gender influences on autistic presentation, whereby children showing the male autism phenotype are rated as more likely to be autistism "looks like" in girls. Also, when given identical descriptions of autistic boys and girls, educators were more likely to identify autism in boys. These results suggest that primary school educators might need extra help to improve the recognition of girls on the autism spectrum.Introduction Lactate accumulation in the brain is caused by the anaerobic metabolism induced by ischemic damages, which always accompanies intracerebral hemorrhages (ICH). Our former findings showed that microglia's movement was always directly toward hemorrhagic center with the highest lactate concentration, and penumbra area has the largest density of compactly arrayed microglia. However, the relationship between microglia and lactate concentration has not been well documented. Methods Cerebral hemorrhage model was successfully achieved by injecting collagenase VII (causing stabile localized bleeding) in CPu (striatum) of SD rats. Emodin was used as a potential therapeutic for ICH. The function of the lactate was examined with in vitro culture studies. Then, the effect of lactate on the proliferation, cell survival, migration, and phagocytosis property of microglia was investigated by in vitro culture studies. Results Lactate accumulation was observed with in vivo MRS method, and its concentration was monitored during the recovery of ICH and treatment of emodin. Lactate concentration significantly increased in the core and penumbra regions of hemorrhagic foci, and it decreased after the treatment of emodin. The in vitro culture study was verified that lactate was beneficial for the proliferation, cell survival, migration, and phagocytosis property of the microglia. Conclusion Results from in vitro verification study, investigations from the recovery of ICH, and treatment of emodin verify that lactate plays an important role during the recovery of ICH. This could provide a novel therapeutic approach for ICH.A series of Er3+ -doped magnesium aluminium layered double hydroxides (Er3+ -doped, MgAl-LDHs) with different Mg2+ /(Al3+ +Er3+ ) molar ratios were synthesized using the hydrothermal method. Compositional and structural analyses suggest that the Er3+ -doped MgAl-LDHs kept a hexagonal structure while the Mg2+ /(Al3+ +Er3+ ) molar ratio was at 1.0-4.1. The downconverted emission spectra of the Er3+ -doped MgAl-LDHs showed a red emission at 650 nm and strong infrared emissions at 720, 780, and 850 nm. These infrared emissions were hardly observed in previous downconverted emission spectra of Er3+ -doped materials. In the analysis of the Er3+ energy levels and in relevant published literature, the energy transfer diagram for Er3+ -doped in MgAl-LDHs is described, and infrared emissions at 720, 780, and 850 nm may be attributed to 4 F7/2 →4 I13/2 , 2 H11/2 →4 I13/2 , and 4 S3/2 →4 I13/2 transitions of Er3+ , respectively. Er3+ -doped MgAl-LDHs could have potential application as marking and targeting agents in the processes for drug delivery in consideration of the strong near-infrared Er3+ emissions, as well as the special layered structure of MgAl-LDH.Howy Jacobs reminisces about his many editorials and asks whether they have ever been read by anyone.Objective Reliable data describing the trends and clinicopathological characteristics of oral squamous cell carcinoma (OSCC) in the Nepalese population are very limited. The current study aimed to examine the demographics, trend, and clinicopathological characteristics of OSCC reported to the main referral/tertiary cancer hospital, the B.P. Koirala Memorial Cancer Hospital (BPKMCH) in Nepal for a period of 11 years (1999-2009). Material and methods This is a cross-sectional study. Data were retrieved retrospectively from hospital register maintained in the Department of Ear, Nose, Throat at BPKMCH, categorized into demographic and clinicopathological variables and SPSS (V25) was used for the analysis. Results In a period of 11 years, 3,452 cases of head and neck cancer were registered at the Department of Ear, Nose, Throat, BPKMCH. Out of 1,111 oral cancer cases, 1,081 (97.3%) were OSCC. A trend for increasing number of OSCCs presenting to BPKMCH was observed during that period. OSCC was found to be more common among males (73.
