The terraces of the pre-MIS 12 Bytham River provide a framework for dating occupation to MIS 13 and 15, while during MIS 11, archaeological sites with rich environmental records can be dated to substage level. We suggest there are six chronologically and typologically distinct assemblage types that reflect a series of population incursions into Britain. We review the broader European lithic record, which is consistent with the Cultural Mosaic Model. In developing the model, we suggest that during stable climate, localized cultures developed, while climatic change led to shifts in population, with increased knowledge exchange and gene flow. We suggest that group expression through material culture was an important stage in social development by promoting group cohesion, larger group size, better cooperation, improved knowledge transfer, and enabling populations to survive in larger foraging territories in northern Europe.A novel series of hydrazone derivatives were designed and synthesized. Their structures were characterized by IR, 1H NMR, 13C NMR and HR-MS spectroscopic methods. The newly synthesized compounds were evaluated for their inhibitory activity against monoamine oxidase enzymes (MAO-A and MAO-B). Compounds 2a, 2k, 4a and 4i showed significant inhibitory activity against MAO-A, with IC50 value in the range of 0.084-0.207 µM compared to reference drug moclobemide (IC50 value = 6.061 µM). These compounds (2a, 2k, 4a and 4i) were exposed to cytotoxicity tests to establish their preliminary toxicological profiles and were found to be non-cytotoxic. Moreover, the most effective compound 4i was evaluated using enzyme kinetics and docking studies to elucidate the plausible mechanisms of inhibition of MAO-A. According to enzyme kinetic studies, compound 4i was a reversible and competitive inhibitor with similar inhibition features as the substrates. Also, it was seen that this compound was settled down very properly at the active site of MAO-A enzyme by doing important interactions owing to the docking studies. Finally, ADME predictions were applied to estimate pharmacokinetic profiles of synthesized compounds. According to calculated ADME predictions, all parameters of the compounds were within the standard ranges in terms of "Rule of Five" and "Rule of Three" and it was detected that the synthesized compounds (2a-4i) have good and promising pharmacokinetic profiles.Two novel series of Dihydropyrimidine-hydroxamic acid hybrids (4a-4l and 5a-5l) were designed, synthesized and evaluated for in vitro Helicobacter pylori urease inhibition. In vitro enzyme inhibition screening led to the discovery of three potent urease inhibitors 2-[[4-(4-hydroxy phenyl)-6-oxo-1,6-dihydropyrimidine-2-yl]-amino]-N-hydroxy acetamide (4g), 2-[[4-(4-chloro phenyl)-6-oxo-1,6-dihydropyrimidine-2-yl]-amino]-N-hydroxy acetamide (4b) and 3-[[4-(3-methoxy phenyl)-6-oxo-1,6-dihydropyrimidine-2-yl]-amino]-N-hydroxy propanamide (5l). Compound 4g showed excellent urease inhibition with IC50 value of 14 ± 1 nM, indicated by its strong interactions with both metallic Ni++ ions, Gly279, His221, Ala365, Asp362, Asn168, Arg338 and His322 residues of the active site of urease. Further, compounds 4b and 5l displayed very good activity with IC50 value of 0.082 ± 0.004 µM and 0.14 ± 0.013 µM respectively compared to standard Acetohydroxamic acid (IC50 - 27.4 ± 1.2 µM). Kinetic studies revealed that a mixed inhibition with both competitive and non-competitive aspects is involved in the urease inhibition mechanism. see more The in vitro urease inhibition results were supported by molecular docking studies. Collectively, this study indicates that 4g could be considered as promising lead molecule that can be further developed as a potent drug molecule for the treatment of Helicobacter pylori caused gastritis for further studies.

Humor and sarcasm may be used as potential coping strategies during challenging times, and to improve wellbeing. We investigated changes in humor and sarcasm use during the COVID-19 pandemic in participants with varying anxiety and depression symptom severity, and in those with versus without psychiatric disorders.

Online data was collected from N=661 Canadian adults during the height of COVID-19-related restrictions. Depression and anxiety symptom severity were assessed using the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder (GAD-7) scale. Participants were queried on current presence/absence of a psychiatric disorder, and on changes in humor and sarcasm use during compared to before the pandemic.

Participants with any vs. no depression symptoms reported more sarcasm and humor use during the pandemic. Respondents with mild and severe vs. no anxiety symptoms reported using more sarcasm. However, those with any vs. no anxiety symptoms used less humor during the pandemic. Finally, lessuring times of distress. Our findings have implications for using humor in therapy in individuals with mental health struggles and mood disorders.

The stare-in-the-crowd (SITC) effect describes the ability to detect self-directed gaze in a crowd. Given the importance of gaze detection in initiating and maintaining social interactions, there is a need to better characterize the SITC effect.

Autistic and neurotypical young adults were presented with four SITC conditions. Eye tracking outcomes and arousal were compared by diagnosis and condition using repeated measures analysis of variance. Hierarchical regression was used to explore behavioral measures.

Significant interaction of diagnosis and condition was found for eye tracking outcomes. Overall, autistic participants exhibited less looking than neurotypical participants. Interest area dwell time, fixation count, and second fixation duration were significantly higher for conditions with shifting gaze, as well as conditions with more self-directed gaze across participants. Two hierarchical regression models of gaze behaviors with advanced theory of mind as a predictor were significant.

Autistic individuals respond to various gaze conditions in similar patterns to neurotypical individuals, but to a lesser extent. These findings offer important targets for social interventions.

The integration of baker's yeast wastewater (BYW) for an innovative two-step waste biorefinery process by producing protein-rich fungal biomass and biogas along with COD and nutrients removal was the main object of the present research. In the first step, fungal biomass production from BYW was investigated using four species of filamentous fungi. The maximum biomass yield of 5.13 g/L BYW containing 43.8% mycoprotein and 36.3% COD removal was achieved by A. oryzae. In the second step, to produce biogas and further remove organic matter, the effluent of fungal fermentation was subjected to anaerobic digestion and COD removal between 22.4 and 44.2% was obtained. Overall, 1 m3 of BYW yielded 5.13 kg of protein-rich biomass and 1.42 m3 of methane. Additionally, pigment production using N. intermedia was investigated, and 1.54 mg carotenoids/g biomass was produced.The feasibility of co-fermentation of food waste and spent mushroom substance for lactic acid with Aspergillus niger cellulase replacing commercial cellulase was explored. In this study, Enterococcus mundtii was used in this study because it could utilize hexose and pentose. When the ratio of food waste and spent mushroom substance was 12, lactic acid concentration was 39.22 g/L, 39.28% higher than the weighted average of experimental lactic acid concentrations, indicating that the co-fermentation had positive synergistic effects. Results showed 92.62% of sugars of pretreated spent mushroom substance was released by Aspergillus niger cellulase. Moreover, when Aspergillus niger cellulase was added into the lactic acid fermentation system at 24 h, lactic acid concentration reached 48.72 g/L, which was 22.97% higher than that of the control group with commercial cellulase, because of the disappearance of Veillonella and Saccharomycetales with the Aspergillus niger cellulase addition, thus making more substrates converted into lactic acid.Due to its rarity, there is a dearth of prospective data on optimal therapeutic strategies in male breast cancer (MBC). Treatment recommendations are mostly extrapolated from evidence in female breast cancer (FBC). Data show that MBC has unique clinical and biological characteristics distinct from FBC. Evidence from retrospective studies suggests that effective therapeutic interventions are often underutilized in MBC and this can compromise outcomes. Population based studies contribute significantly towards the understanding of rare cancers. Multiple studies have demonstrated that adjuvant radiation is associated with improved local control and survival in high risk subgroups of MBC. Multi-center consortia studies contribute significantly towards generating prospective data and optimizing diagnostic and therapeutic strategies in these rare cancers. Enhancing the implementation of treatment recommendations and minimizing disparities in access to care will lead to improved outcomes.This study evaluated the impact of the TLR7 Gln11Leu (rs179008) and TLR9 -1237 T/C (rs5743836) single nucleotide polymorphisms (SNPs) on susceptibility to placental infections and pregnancy complications in 455 Brazilian women. Demographic, socioeconomic, gynecological, and clinical characteristics of the women were collected. Placental tissues were sampled from pregnant women and human and viral DNA was extracted. Human alphaherpesvirus 1 (Herpes simplex virus type 1, HSV-1), Human alphaherpesvirus 2 (Herpes simplex virus type 2, HSV-2) and Human betaherpesvirus 5 (Human cytomegalovirus, HCMV) were detected by nested PCR. TLR9 and TLR7 SNPs were genotyped by PCR amplification of bi-directional specific alleles (Bi-PASA) and restriction fragment length polymorphism (RFLP), respectively. Infections at the time of birth were detected in 45.71 % of women. The presence of the TT genotype (recessive model) of the TLR7 SNP was associated with increased susceptibility to HSV-1 infection (O.R. = 2.23, p = 0.05). The presence of the C allele of the TLR9 SNP, in heterozygosis or homozygosis (dominant model), decreased the infection risk by HCMV (O.R. = 0.31, p-mod less then 0.05). The TT genotype (recessive model) of the TLR7 SNP was significantly associated (p  less then  0.05) with increased occurrence of pre-treated hypertension. The codominant model of the TLR9 SNP was significantly associated (p  less then  0.05) with reduced risk of hospitalization during pregnancy. In combination, the AA/CT (TLR7-TLR9) genotypes significantly decreased the risk of placental infection by HSV-1 and/or HSV-2 (O.R. = 0.47, p = 0.02), the susceptibility to all infectious agents considered in combination (O.R. = 0.4, p = 0.00), and the need of hospitalization (O.R. = 0.48, p = 0.02). In conclusion, TLR7 and TLR9 SNPs are potential modulating factors for the risk of placental infections and pregnancy complications.
