In this paper, a series of novel derivatives of camptothecin substituted norcantharimide was designed by mimic strategy. These compounds were synthesized in moderate yields by directly coupling CPT with N-amino acid norcantharimides. Their cytotoxicity to four human tumour cell lines (HepG2, BGC-803, SW480 and PANC-1) and normal human cell lines L-O2 and HIEC was evaluated. The synthesized CPT substituted norcantharimide analogs (3g and 3f) showed better anti-hepatocarcinoma activity than CPT. Compounds 3d, 3e, 3g, 3h and 3i also showed strong inhibition activity against BGC803.The ecology of a biofilm is a complex function of different factors, including the presence of microbial metabolites excreted by the inhabitants of the biofilm. This study aimed to assess the effect of patulin, and N-(3-oxododecanoyl)-L-homoserine lactone (3-oxo-C12-HSL) on inter-kingdom biofilm formation between a filamentous fungus and bacteria isolated from drinking water. The filamentous fungus Penicillium expansum and the bacteria Acinetobacter calcoaceticus and Methylobacterium oryzae were used as model species. M. oryzae biofilm formation and development was more susceptible to the presence of the quenching molecules than A. calcoaceticus biofilms. Patulin reduced M. oryzae biofilm growth while 3-oxo-C12-HSL caused an increase after 48 h. The presence of P. expansum had a detrimental effect on M. oryzae cell numbers, while an advantageous effect was observed with A. calcoaceticus. The overall results reveal that quorum sensing and quenching molecules have a significant effect on inter-kingdom biofilm formation, especially on bacterial numbers.Angiotensin-converting enzyme 2 (ACE2) facilitates the cellular entry of the severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2), which causes the coronavirus-2019 (COVID-19) disease. Recent reports have shown worse outcomes in men with COVID-19 infection compared to women. We review the hypothesis that sex-related differences in outcomes in COVID-19 are due to different activity of ACE2 between men and women. HSP990 We also show that studies in humans have demonstrated no significant difference in serum ACE2 levels between healthy men and women. However, men with hypertension and heart failure typically have higher level of serum ACE2 activity compared to women. We hypothesize that the worse outcomes in men with COVID-19 compared to women is likely due to higher prevalence of hypertension and heart failure among men compared to women. To test this hypothesis, studies to compare the outcomes of COVID-19 infection between men and women with no preexisting heart diseases are needed.
Severity of unilateral coronal synostosis (UCS) can vary. Quantification is important for treatment, expectations of treatment and natural outcome, and education of the patient and parents.
Retrospective study.
Primary craniofacial center.
Twenty-three preoperative patients with unilateral coronal craniosynostosis (age < 2 years).
Utrecht Cranial Shape Quantifier (UCSQ) was used to quantify severity using the variables asymmetry ratio of frontal peak and ratio of frontal peak gradient.
The UCSQ variables were combined and related to visual score using Pearson correlation coefficient; UCSQ and visual score were additionally compared to Di Rocco classification by one-way analysis of variance or Kruskal-Wallis test. All measurements were made on computed tomography scans.
Good correlation between UCSQ and visual score was found (
= 0.67). No statistically significant differences were found between group means of UCSQ in the 3 categories of Di Rocco classification (
= 0.047;
> .05). Kruskal-Wallis test showed no significant differences between group means of visual score in the 3 categories of Di Rocco classification (Kruskal-Wallis
(2) = 0.871;
> .05).
Using UCSQ, we can quantify UCS according to severity using characteristics, it outperforms traditional methods and captures the whole skull shape. In future research, we can apply UCSQ to 3D-photogrammetry due to the utilization of external landmarks.

Caring for loved ones with palliative needs can be very stressful for carers'. To address this growing issue, an online Home Caregiver Support Program course was created to provide information to non-professional home caregivers about end-of-life care.
To measure non-professional caregivers' perceived level of competence in addressing physical, psychological, social, and spiritual needs before and after completing online training modules.
Learners rated their competence before and after completing online modules addressing 4 key dimensions relevant to palliative caregivers. Self-ratings of competence were assessed through surveys, completed before and after the online modules. Scores from before and after each module were compared to determine if the online course had increased participant competence. The Wilcoxon signed rank test was used to analyze participant responses to the pre- and post-survey questions.
A total of 176 participants who completed one or more of the online modules between July 2017-December 2018, 70 (40%) of the participants completed at least one pre- and post-module survey and did not declare themselves as a professional caregiver. Participating in the online Home Caregiver Support Program increased participants' ratings of perceived competence in all domains (p < .01). This significance was maintained when professional caregivers were added to our analysis.
After the completing the modules, participants' self-ratings of perceived competence increased suggesting that participants completing the online program had improved knowledge in addressing the physical, psychological, social, and spiritual challenges faced by non-professional caregivers.
