Although grief is a reaction to a social loss, it has been viewed almost exclusively through the lens of individual psychology and not sociology. In this article, we suggest that more attention to sociological aspects of grief is warranted. We propose a micro-sociological theory of bereavement and grief to complement, not replace, psychological perspectives. We assert that bereavement represents a state of loss-associated social deprivations (e.g. social disconnection). Furthermore, we postulate that addressing social deprivations (e.g. Entinostat HDAC inhibitor enhancing social connection) will lessen severity of distressing, disabling grief and, thereby, promote adjustment to loss. Future research is needed to test our theory and the hypotheses that follow from it in the service of promoting adaptation to bereavement.Epilepsy is one of the foremost medical disorders. Oxidative stress is a well-known mechanism in epileptogenesis, and many studies suggest that oxidative stress affects the onset and evolution of epilepsy. Here we evaluated the walnut peptide extracts' anti-seizure property in three different mouse seizure models including pentylenetetrazole-induced clonic seizure, chemical kindling, and maximal electroshock. Walnut peptides (20 mg/Kg) were administered by intraperitoneal (IP) injection of mice 60 min before seizure induction in the three models. To delineate the mechanisms of walnut peptides anti-seizure activity, we evaluated the impact of diazepam, flumazenil, and a NOS inhibitor on this activity. Intraperitoneal administration of walnut peptides significantly increased the seizure threshold. Our results also demonstrated that walnut peptides exert their anti-seizure properties through the modulation of benzodiazepine receptors. Thus, walnut peptides may be considered as a new anti-convulsion agent, which can reduce seizure occurrence and slow down seizure progression.

There are three recommended first-line treatments for infantile spasms, adrenocorticotropic hormone (ACTH), oral corticosteroids, and vigabatrin, though non-standard treatments such as topiramate are sometimes selected. Is it uncertain how treatment selection influences health services outcomes.

We conducted a retrospective cohort study of Medicaid beneficiaries newly diagnosed with infantile spasms from 2009-2010. We included infants with a new diagnosis of infantile spasms between age 2-9 months who filled ACTH (reference), prednisolone, vigabatrin, or topiramate prescriptions. Multivariable Cox proportional hazards regression compared time to first emergency department (ED) visit or hospitalization across treatment groups during 2 years of follow-up. Monthly costs for each treatment were examined in 6-month intervals and compared in a multivariable generalized linear model.

Among 256 children with infantile spasms, 116 received ACTH, 62 prednisolone, 15 vigabatrin, and 63 topiramate. The rate of ED v efficacy, and merits additional research.

Compared to other treatments for infantile spasms, use of ACTH was associated with greater cost in the first 6 months of treatment, but not with reduced ED visits or hospitalizations. The cost effectiveness of ACTH depends on its relative clinical efficacy, and merits additional research.Hydrogen gas (H2) mediation of lateral root (LR) branching was previously described. However, related signaling pathway is largely unexplored. In this study, we discovered that application with H2 using hydrogen-rich water, mimicking the responses of exogenous glutathione (GSH), not only enhanced GSH synthesis, but also induced tomato LR development. The changes in the transcripts of auxin signaling-related genes and cell cycle regulatory genes were matched with above phenotypes. The addition of H2 could trigger higher transcript levels of SlGSH1 and SlGSH2, encoding γ-glutamylcysteine synthetase (γ-ECS) and glutathione synthetase (GS), confirming the stimulation of GSH synthesis. These responses were greatly abolished when the inhibitor of γ-ECS was applied. The inhibition in lateral root primordium development, especially in emergence stage, was also observed. Genetic evidence revealed that the defects in GSH production and lateral rooting in Arabidopsis cad2-1, a γ-ECS defective mutant, were obviously abolished in the presence of GSH compared to those in the presence of H2. Further evidence revealed that mRNA levels of target genes elicited by H2 in wild-type, were differentially impaired in mutant plants. Together, above data clearly demonstrated that γ-ECS-dependent GSH production might be closely associated with H2 control of LR branching.

To conduct a longitudinal ecological analysis of the distance to and participation in free weekly outdoor physical activity events (parkrun) in England from 2010 to 2019, and related socioeconomic and ethnic inequalities, to inform policies to support participation in physically active community events.

We calculate distance to the nearest parkrun event for each English Lower Layer Super Output Area (LSOA) each month from January 2010 to December 2019. We then report the trends in distance to and participation in parkrun by Index of Multiple Deprivation quintile. We also report trends in the Relative Index of Inequality (RII) by deprivation for participation and distance to nearest event. We go on to investigate trends in LSOA level determinants (e.g. deprivation and ethnic density) of parkrun participation between 2010 and 2019, using multivariable Poisson regression models.

Mean distance to the nearest parkrun event decreased from 34.1km in 2010, to 4.6km in 2019. Throughout the period, parkrun eventsce of the most deprived areas was 29% that of the least deprived. Participation was shown to have increased over the past 10 years which can be split into two distinct phases from 2010 to 2013 participation increased super-linearly and inequality in participation fell dramatically; from 2013 to 2019 participation increased linearly, and inequality in participation remained stable. Despite parkrun's ambitions of creating inclusive events and engaging with deprived communities, the socioeconomic gradient in participation rates remained high and stable since 2013. Gaining a better understanding of the reasons why parkrun grew so quickly may be useful for other physical activity movements, while further analysis of the relatively lower participation rates in areas with higher socioeconomic deprivation is important for developing initiatives to encourage physical activity in these communities.Diuron, a commonly used herbicide and antifouling biocide, has been frequently detected in seawater. The effects of diuron on fish behaviour are currently poorly understood. Herein, the marine medaka (Oryzias melastigma) was continuously exposed to environmentally realistic levels of diuron from the fertilised egg stage to the adult stage. Behavioural evaluation of adult marine medaka indicated that exposure to diuron increased anxiety in the light-dark test and increased predator avoidance. In addition, diuron exposure significantly reduced aggression, social interaction, shoaling, and learning and memory ability. However, only negligible variations in foraging behaviour and in behaviour in the novel tank test were observed. Marine medaka chronically exposed to diuron also showed decreased levels of dopamine in the brain, and changes were observed in the transcription of genes related to dopamine synthesis, degradation and receptors. Exposure to 5000 ng/L diuron caused significant downregulation of the expression of the genes of tyrosine hydroxylase and monoamine oxidase and significantly upregulated the expression of the genes of the D5 dopaminergic receptor. The relative expression of the D4 dopaminergic receptor was significantly upregulated in the 50, 500 and 5000 ng/L diuron-treated groups. These findings highlight the significant neurotoxic effects of diuron and the extent to which this may involve the dopaminergic system of the brain. More broadly, this study reveals the ecological risk associated with environmentally realistic levels of diuron in marine animals.The role of COX-2 induced PGE2 in the site-specific regulation of inflammatory mediators that facilitate disparate wound healing in the tail and limb of a lizard was studied by analysing their levels during various stages of healing. The activity of COX-2 and concentration of PGE2 surged during the early healing phase of tail along with the parallel rise in EP4 receptor. PGE2-EP4 interaction is corelated to early resolution (by 3 dpa) of inflammation by rising the antiinflammatory mediator IL-10. This likely causes reduction in proinflammatory mediators viz., iNOS, TNF-α, IL-6, IL-17 and IL-22. Conversely, in the limb, COX-2 derived PGE2 likely causes rise in inflammation through EP2 receptor-based signalling, as all the proinflammatory mediators stay elevated through the course of healing (till 9 dpa), while expression of IL-10 is reduced. This study brings to light the novel roles of IL-17 and IL-22 in programming wound healing. As IL-17 reduces in tail, IL-22 behaves in reparative way, causing conducive environment for scar-free wound healing. On the contrary, synergic elevation of both IL-17 and Il-22 form a micro-niche suitable for scarred wound healing in limb, thus obliterating its regenerative potential.N-methyl-d-aspartate receptors (NMDARs) are expressed abundantly in the brain and play a crucial role in the regulation of central nervous system (CNS) development, learning, and memory. During early neuronal development, NMDARs modulate neurogenesis, neuronal differentiation and migration, and synaptogenesis. The present study aimed to examine the developmental expression of NMDARs subunits, NR1 and NR2B, in the developing hippocampus of neonatal rats during the first two postnatal weeks. Fifty-four male offspring were randomly divided into three age groups, postnatal days (P) 0, 7, and 14. Real-time-PCR, western blotting, and immunohistochemistry (IHC) analyses were employed to examine and compare the hippocampal expression of the NMDA receptor subunits. The highest mRNA expression of NR1 and NR2B subunits was observed at P7, regardless of its laterality. The mRNA expression of both subunits in the right hippocampus was significantly higher than that of the left one at P0 and P7. Similarly, the highest protein level expression of NR1 and NR2B subunits was also observed at P7 in both sides hippocampi. Although the protein expression of NR1 was significantly higher on the right side in all studied days, the NR2B was significantly higher in the right hippocampus only at P7. The analysis of optical density (OD) has shown a marked increase in the distribution pattern of the NR1 and NR2B subunits at P7 in all hippocampal subregions. In conclusion, there is a marked right-left asymmetry in the expression of NR1 and NR2B subunits in the developing rat hippocampus, which might be considered as a probable mechanism for the lateral differences in the structure and function of the hippocampus in rats.

Endometriosis is a disease that significantly affects the quality of life of patients. Continuous pelvic pain seen in patients disrupts their well-being. The aim of this study is to examine the changes in depression and sleep disorders in patients with endometriosis before and after the operation.

Forty-two women aged 18-49 with an indication for operation due to the diagnosis of stage 4 endometriosis and without a known psychiatric disorder were included in the study. Pittsburgh Sleep Quality Index and Beck Depression Inventory were used to compare sleep quality and mood of endometriosis patients before and after surgery.

The mean age of the patients was 33.8±7.6. The mean BMI of the patients was 24.6±4.1. Endometrioma diameter was 248.42±95.7cm3 in patients with poor sleep quality, while it was 296.11±271.53cm3 in patients with good sleep quality, and a significant difference was observed (p<0.05). Poor sleep quality and severe depression were significantly higher in patients with infertility complaints.
