ATR inhibition has been shown to act synergistically with PARP inhibition and other cancer treatments to enhance anti-tumour activity. ATM-deficiency is a common characteristic of PCa and a synthetic lethal relationship exists between ATM and ATR, with ATR inhibition inducing selective cell death in ATM-deficient PCa cells. The current research highlights the feasibility of therapeutically targeting ATR in ATM-deficient prostate tumours and in combination with other treatments to enhance overall efficacy and reduce therapeutic resistance. ATM also represents an important molecular biomarker to stratify patients into targeted treatment groups and aid prognosis for personalised medicine.
How recoding of fnr, an anaerobic regulatory gene, affects pathogenicity related parameters of Salmonella Typhimurium (STM).
The fnr gene was recoded by substituting all of it's codons with synonymous rare codons of STM. Recoding fnr gene severely reduced the ability of the recoded mutant to compete with wild strain under nutrient depletion condition. Mutants were also less motile than the wild strain and their biofilm forming ability was significantly decreased as compared to wild strain. The recoded strain showed significant reduced survival within murine macrophages (RAW264.7) and monocyte derived macrophage of poultry origin. The colonisation ability of recoded mutant in liver and spleen of mice on day 5 of post infection was significantly reduced. The recoded strain exhibited significant reduction in faecal shedding on day 1 and 5 after infection.
Our study showed that recoding the anaerobic regulator fnr of STM significantly compromised its growth, decreased motility, biofilm forming ability and survival within macrophages. Further, the recoded fnr strain showed reduced colonisation ability and faecal shedding in mice. Thus, these findings highlight that recoding the global anaerobic regulator fnr of Salmonella Typhimurium attenuates its pathogenicity.

We aimed to investigate associations of unclean cooking fuels with depression and anxiety symptoms in a large sample of adults aged ≥65years from six low- and middle-income countries (LMICs).
Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. Unclean cooking fuel referred to kerosene/paraffin, coal/charcoal, wood, agriculture/crop, animal dung, and shrubs/grass. Depression referred to DSM-IV depression based on past 12-month symptoms or receiving depression treatment in the last 12months. Anxiety symptoms referred to severe/extreme problems with worry or anxiety in the past 30days. Multivariable logistic regression analysis and meta-analysis were conducted.
Data on 14,585 people aged ≥65years were analyzed [mean (SD) age 72.6 (11.5) years; maximum age 114years; 55.0% females]. ABT-737 cell line After adjustment for potential confounders, unclean cooking fuel was associated with a significant 2.52 (95%CI=1.66-3.82) times higher odds fthe United Nations Sustainable Goal 7, which advocates affordable, reliable, sustainable, and modern energy for all.
This study aimed to determine the prevalence of substance consumption and mental health problems among Spanish medical students, and their association with sociodemographic factors.
A multicentre cross-sectional study was conducted. Self-reported data on sociodemographic and clinical characteristics were collected, including BDI-II, PHQ-9, brief STAI, and single-item academic burnout (IUBA).
Overall, 1265 students (74.2% female) completed the survey. Of them, 37.4% scored positive for depressive symptoms, as measured by the BDI-II, and more than half (53%) by the PHQ-9. Suicidal ideation was reported by about 12% whilst high levels of state and trait anxiety were informed by 28.8% and 29.4% of the students. The prevalence of burnout was 40.2%. Female and pre-clinical students reported significantly (p<0.01) higher rates of depressive, anxiety, and burnout symptoms. Alcohol, energy drinks, and tobacco were the most frequently used substances. Total scores of self-reported mental health problems negatively correlated (p<0.001) with objective academic results and positively correlated (p<0.02) with the number of substances consumed in the last 30days.
Research-based on self-reported data could favour information bias due to the social desirability effect and memory error.
A high prevalence of substance consumption and several mental health problems was found among medical students, especially females. The relevant influence of academic-related factors on students' well-being may be a call for medical schools to implement initiatives aimed to improve students' ability to detect, address, and seek help for their mental health issues.

Maternal depression and anxiety in the perinatal period affect the quality of maternal sensitivity and mentalizing abilities. Few studies analyzed implicit mentalizing in relation to maternal distress. The aims of the study were to examine the relation between nonverbal mentalizing - parental embodied mentalizing (PEM) - and maternal depression and anxiety, verbal mentalizing, and maternal styles of interaction; and to test PEM as a mediator of the effect of maternal distress on styles of interaction.
81 mother-infant dyads have been recruited. At infant three months, maternal depression was assessed using the Edinburgh Postnatal Depression Scale, anxiety with State Trait Anxiety Inventory, and reflective functioning with Reflective Functioning Scale. Mother-infant interactions were coded with various approaches PEM for nonverbal mentalizing, Mind-mindedness coding system for Mind-mindedness, and CARE-Index for maternal styles of interaction.
Maternal depression and state anxiety were negatively correla programs for mothers focused also on implicit mentalizing.
The assessment of psychological well-being and euthymia represents an emerging issue in clinical psychology and psychiatry. Rating scales and indices such as the 5-item version of the World Health Organization Well-Being Index (WHO-5) and the Euthymia Scale (ES) were developed but insufficient attention has been devoted to the evaluation of their cross-cultural validity. This is the first study using Clinimetric Patient-Reported Outcome Measures (CLIPROM) criteria to assess cross-cultural validity and sensitivity of five different versions of the WHO-5 and ES.
A multicenter cross-sectional study involving a total of 3762 adult participants from different European (i.e., Italy, Poland, Denmark) and non-European (i.e., China, Japan) countries was conducted. Item Response Theory models (Mokken and Rasch analyses) were applied.
Mokken coefficients of scalability were found to range from 0.42 to 0.84. The majority of the versions of the WHO-5 fitted the Rasch model expectations. Paired t-tests revealed that the Italian and Danish WHO-5 versions were unidimensional. Person Separation Reliability indices showed that the Polish, Danish, and Japanese ES versions could reliably discriminate between subjects with different levels of euthymia.
A convenience sampling was used, thus limiting the generalizability of study findings. In addition, no measures of negative mental health were administered.
WHO-5 can be used in international studies for cross-cultural comparisons since it covers transcultural components of subjective well-being. Findings also suggest that the ES can be used as a cross-cultural screening tool since it entailed the clinimetric property of sensitivity.

Peritrophins have essential roles in providing porosity and strength to the PM that lines the shrimp midgut. Acute hepatopancreatic necrosis disease (AHPND), caused by strains of V. parahaemolyticus, is known to initially colonize the shrimp stomach and simultaneously disrupt its structural barriers (e.g., cuticle or epithelial tissues) to reach the hepatopancreas. Although stomach and hepatopancreas were identified as target tissues involved in AHPND pathogenesis, our results indicated that peritrophin in peritrophic membrane has a crucial role in determining not only colonization of AHPND-causing bacteria but also their tissue distribution. As the interaction between LvPeritrophin (LvPT) and WSSV (white spot syndrome virus) is not well understood, we noted that LvPT expression was upregulated in shrimp stomach challenged with either WSSV or AHPND. In an in vitro pathogen binding assay, there was strong binding of recombinant LvPT WSSV and AHPND-causing V. parahaemolyticus, and various bacteria. Furthermore, dsRNA-mediated LvPT silencing inhibited WSSV gene expression and viral genome replication. However, downregulation of LvPT gene expression increased copies of AHPND-causing bacteria in shrimp digestive tract, and facilitated bacterial colonization in stomach. In conclusion, we speculated that LvPT might regulate bacterial colonization during AHPND, whereas in WSSV infection, LvPT silencing favored the host. Although recombinant LvPT had strong binding with WSSV, the precise role of LvPT in WSSV infection needs further investigation. These findings increased our understanding of host-pathogen interactions in AHPND and WSSV infection that can be applied in shrimp aquaculture for developing effective antibacterial and antiviral strategies.Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) in mammals is a multifunctional protein. In this study, PCSK9 of marine fish Epinephelus coioides was characterized. The full-length cDNA of E. coioides PCSK9 was 2458 bp in length containing 185 bp 5' UTR, 263 bp 3' UTR and 2010 bp open reading frame (ORF) encoding 669 amino acids with the predicted molecular weight of 71 kDa and the theoretical PI of 6.6. Similar to other members of PCSK9 family, E. coioides PCSK9 has three conserved domains Inhibitor_ I9 super family, Peptidases_ S8_ PCSK9_ Proteinase K_ like, and PCSK9_ C-CRD super family. E. coioides PCSK9 mRNA could be detected in all the tissues examined by real-time quantitative PCR, with the highest expression in the brain, followed by skin, trunk kidney, head kidney, intestine, blood, liver, spleen, gill, muscle and heart. E. coioides PCSK9 was distributed in both the cytoplasm and nucleus. The expression of E. coioides PCSK9 was significantly upregulated during Singapore grouper iridovirus (SGIV) infection.
