The role of imperforate tracheary elements and narrow vessels in wood capacitance of angiosperm trees
Authors: Ziemińska Kasia 
Published: March 2023

Summary
There is a broad diversity of imperforate tracheary elements (ITEs) — libriform fibers, fiber-tracheids, true tracheids and vasicentric/vascular tracheids — described thoroughly by Sherwin Carlquist. However, in a quantitative sense, the functional meaning of different ITE types present in the wood of vessel-bearing angiosperms remains unclear because very few structure–function studies measure ITEs’ properties. ITEs with abundant pits and wide pit borders — vascular tracheids, vasicentric tracheids, and true tracheids sensu Carlquist — have been shown to conduct water and, thanks to this conductive ability and the multitude of pits, they could also contribute to wood capacitance. A dataset of 30 temperate angiosperm tree species was reanalysed to record the presence/absence of true, vasicentric, and vascular tracheids including data on conduits15 fraction and vessel-conduit15 contact fraction (conduits15 were defined as cells resembling vessels and with a maximum lumen diameter of 15 μm. They encompassed narrow vessels, vasicentric tracheids, and vessel tails). The presence of tracheids, conduits15 fraction, and contact fraction had no effect on wood capacitance, except, per given wood volumetric lumen water content, species with true tracheids tended to have lower capacitance. These results suggest that the presence of tracheids or conduits15 properties do not limit wood capacitance, but the results do not exclude the potential role these cells may play in internal water dynamics.
Genuine Explanation and the Strong Minimalist Thesis

Abstract
The goal of theoretical inquiry is explanation: Why this, and not that? In the study of language, search for explanatory theory proceeds at two levels: for individual languages (a generative grammar in the broad sense) and for the general faculty of language fl (ug), the latter apparently a true species property, common to humans and without significant analogue in the animal world. ug must meet several conditions: learnability, evolvability, coverage. These conditions appear to conflict, and are far more severe than had earlier been supposed. A solution to the conundrum would be satisfaction of smt for ug combined with recourse to language-independent principles of computational efficiency, with diversity sequestered in components of language subject to simple algorithmic search. For the first time, hopes for such an outcome seem to be on the horizon, with significant implications if the hopes can be realized. I will outline some current work on these topics.

Abstract
For modern Earth, the annual-mean equatorial winds in the upper troposphere are flowing from east to west (i.e., easterly winds). This is mainly due to the deceleration effect of the seasonal cross-equatorial Hadley cells, against the relatively weaker acceleration effect of coupled Rossby and Kelvin waves excited from tropical convection and latent heat release. In this work, we examine the evolution of equatorial winds during the past 250 million years using one global Earth system model, the Community Earth System Model version 1.2.2 (CESM1.2.2). Three climatic factors different from the modern Earth—solar constant, atmospheric CO2 concentration, and land–sea configuration—are considered in the simulations. We find that the upper-tropospheric equatorial winds change sign to westerly flows (called equatorial superrotation) in certain eras, such as 250–230 and 150–50 Ma. The strength of the superrotation is below 4 m s−1, comparable to the magnitude of the present-day easterly winds. In general, this phenomenon occurs in a warmer climate within which the tropical atmospheric circulation shifts upward in altitude, stationary and/or transient eddies are relatively stronger, and/or the Hadley cells are relatively weaker, which in turn are due to the changes of the three factors, especially CO2 concentration and land–sea configuration.

Abstract
The Madden–Julian oscillation (MJO) exhibits pronounced seasonality, with one of the key unanswered questions being the following: what controls the maximum in MJO precipitation variance in the Southern Hemisphere during boreal winter? In this study, we examine a set of global climate model simulations in which the eccentricity and precession of Earth’s orbit are altered to change the boreal winter mean state in an attempt to reveal the processes that are responsible for the MJO’s amplitude in the boreal winter. In response to the forced insolation changes, the north–south asymmetry in sea surface temperature is amplified in boreal fall, which intensifies the Hadley circulation in boreal winter. The stronger Hadley circulation yields higher mean precipitation and stronger mean lower-tropospheric westerlies in the southern part of the Indo-Pacific warm pool. The MJO precipitation variability increases significantly where the mean precipitation and lower-tropospheric westerlies strengthen. In the column-integrated moisture budget of the simulated MJO, only surface latent heat flux feedback shows a trend that is consistent with the MJO’s amplitude, suggesting an important role for the surface latent heat flux feedback in the MJO’s amplitude during the boreal winter. An analysis of the moisture–precipitation relationship in the simulations shows that the increase in the mean precipitation lowers the convective moisture adjustment time scale, leading to the increase in precipitation variance. Our results suggest that the mean-state precipitation plays a critical role in the maintenance mechanism of the MJO.

Objectives Periodontal disease is a multifactorial inflammatory disease that can have major welfare implications in cats. This study aimed to report the frequency and demographic risk factors of periodontal disease and to explore associations with common comorbid disorders in cats in the UK. Methods The study included a random sample of 18,249 cats obtained from 1,255,130 cats under primary care during 2019 from clinics participating in the VetCompass programme. All disorders recorded during 2019 were extracted and reported. Risk factor and comorbid disorder analysis used multivariable logistic regression modelling. Results Periodontal disease had a 1-year period prevalence of 15.2% (95% confidence interval [CI] 14.72–15.76). Breeds with the highest prevalence included Siamese (18.7%, 95% CI 12.24–26.72) and Maine Coon (16.7%, 95% CI 11.37–23.18). The median age of cats with periodontal disease (9.47 years, interquartile range [IQR] 5.96–12.97) was higher than for cats without periodontal disease (4.94 years, IQR 1.95–9.51; P <0.001). Increasing adult body weight, increasing age and sex–neuter status were significantly associated with rising odds of periodontal disease. Cats with periodontal disease had a higher median count of comorbid disorders per individual cat (3, IQR 2–4, range 1–14) than cats without periodontal disease (1, IQR 0–2, range 0–15; P <0.001). Cats with periodontal disease had 1.79 times the odds (95% CI 1.62–1.99, P <0.001) of diagnosis with at least one comorbid disorder disease than cats without periodontal disease. Conclusions and relevance Periodontal disease is the most common specific diagnosis in cats and is confirmed as a leading health issue in cats. Ageing is identified as the strongest predictor of periodontal disease risk in cats, suggesting the potential for increasing health gains from emphasis on dental care and health in cats as they age. The study offers evidence on a close link between periodontal disease and reduced overall health in cats.

Bacopa monnieri is an important medicinal plant widely used in various food systems and gaining interest these days for its health benefits such as boosting brain function and improving quality of life. The objective of the present study was to examine the safety of Bacognize®, a standardized botanical extract obtained from the whole herb Bacopa monnieri (L.) Wettst., in subchronic toxicity and genotoxicity studies conducted in compliance with Good Laboratory Practice (GLP) and test guidelines established by the Organization for Economic Cooperation and Development (OECD). In the subchronic toxicity study, treatment with Bacognize® did not result in any toxicologically significant treatment-related changes in clinical observations, and in the clinical pathology as studied by hematology, serum chemistry, urinalysis, and terminal necropsy. Treatment-related adverse effects were not observed in ophthalmic examinations, body weights, body weight gains, feed consumption, and organ weights. The results of genotoxicity studies as assessed by gene mutations in Salmonella typhimurium, in vitro chromosome aberrations and in vivo micronucleus test did not reveal any genotoxicity of Bacognize ®. The no-observed-adverse-effect level (NOAEL) for Bacognize® was established based on the subchronic study and was determined as at least 1000 mg/kg bw/day. These results indicate that Bacognize® does not cause significant adverse effects and suggest its tolerability up to 1000 mg/kg (highest dose tested) for the daily administration of 90 days in rats.
Phosphoproteomic analysis on ovarian follicles reveals the involvement of LSD1 phosphorylation in Chicken follicle selection

Abstract
Background
Follicle selection in chickens refers to the process of selecting one follicle from a group of small yellow follicles (SY, 6–8 mm in diameter) for development into 12–15 mm hierarchal follicles (usually F6 follicles), which is controlled by sex hormones including follicle-stimulating factor (FSH), estrogen and progesterone. Follicle selection is a critical process impacting egg production in chicken, therefore, is the focus of many studies. Phosphorylation is important for the proper function of proteins, thus, needs to be analyzed by proteomic level.

Result
In this study, we compared the phosphoproteomes of SY and F6 follicles in laying hens and identified 2,386 phosphoproteins and 5,940 phosphosites, of which 4,235 sites of 1,963 phosphoproteins were quantified. From SY to F6 follicles, 190 phosphorylation sites of 149 proteins changed significantly, among which the phosphorylation level of lysine demethylase 1 A (LSD1) at the conserved 54th serine (LSD1Ser54p) was significantly upregulated in F6 follicles compared to SY follicles (p < 0.05); however, the expression of chicken LSD1 were not significantly different on both mRNA and protein levels. LSD1Ser54p is mainly located in the nucleus of both SY and F6 follicles, and was higher in F6 follicles than that of SY follicles revealed by both immunofluorescence and Western blotting. LSD1Ser54p level increased after treatment with 5 ng/mL and 10 ng/mL of FSH in the theca cells and the granulosa cells of pre-hierarchal follicles, and with 50 ng/mL in granulosa cells of hierarchal follicles. In the theca cells of hierarchal follicles, estrogen stimulated the level of LSD1Ser54p in a dosage-dependent manner, and in granulosa cells of pre-hierarchal follicles, 10 ng/mL of estrogen increased LSD1Ser54p expression. Treatment with 50 ng/mL of progesterone increased LSD1Ser54p expression in theca cells of pre-hierarchal follicles, and with 10 to 100 ng/ml enhanced LSD1Ser54p expression in the granulosa cells of hierarchal follicles.

Conclusion
The expression dynamics of LSD1Ser54p in follicles from SY to F6 and its regulation by sex hormones suggest that it is involved in chicken follicle selection.
When disaster strikes: staff recall and the use of staff recall systems during mass patient influx at Norwegian emergency primary health care centers – a cross-sectional study
Authors: Friberg Fredrik Femtehjell , Nilsson Heléne , Leonardsen Ann-Chatrin Linqvist 
Published: March 2023

AbstractBackgroundIn Norway, planning for disasters has been specifically emphasized since the incidents on July 22nd,2011. Every municipality is now legislated to have a contingency plan that includes plans for staff recall during situations with mass influx of patients. Whether the primary health care services in Norway are prepared for mass influx of patients remains unclear.Aims of the studyThe aims of this study were (1) to assess the experiences of head doctors at emergency primary health care centers (EPHCC) in Norway with mass influx of patients, (2) to explore mass influx and staff recall procedures in use, (3) to assess head doctors’ experiences with staff recall systems, and (4) to assess their perspective on automatized staff recall systems. We also wanted to assess whether there were differences between small and large EPHCCs regarding whether they had plans in place.MethodsThe study had a cross-sectional, multicenter design, using a self-developed questionnaire. The questionnaire was developed utilizing recommendations from the Delphi technique, including an expert group and piloting. A purposive sampling strategy was used, including head doctors from Norwegian EPHCCs (n = 169). Data were analyzed using the Statistical Package for the Social Sciences, and included descriptive statistics, Chi-Square tests and Shapiro-Wilks. Free-text answers were analyzed by content analysis.ResultsA total of 64 head doctors responded to the questionnaire. The results show that 25% of the head doctors had experienced mass influx of patients at their EPHCC. In total 54.7% of Norwegian EPHCCs did not have disaster plans that consider mass influx situations. The majority of EPHCCs plan to recall staff one by one (60.3%) or through Short-Message-Systems (34.4%). Most EPHCCs had available telephone “alarm” lists (81.4%), that are updated regularly (60.9%). However, only 17.2% had plans that consider loss of mobile phone connection or internet. In total, 67,2% of the head doctors reported to have little experience with automatized staff recall systems, and 59,7% reported to have little knowledge about such systems. There were no significant difference between small and large EPHCCs in having plans or not.ConclusionEven though our results show that few EPHCCs experience mass influx of patients, it is important to be prepared when such incidents do occur. Our results indicate that it is still potential for improvement regarding plans for staff recall and implementation of staff recall systems at Norwegian EPHCCs. Involving national disaster medicine experts in the process of generating tools or checklists could aid when constructing disaster plans. Education and implementation of training for mass influx situations at all levels should always be highlighted.
Environmental factors influencing women’s childbirth experiences in labor–delivery–recovery–postpartum unit: a qualitative cross-sectional study

Published: March 2023

Abstract
Background
Women’s experiences of birth environment influence their mental health and that of their families. Identifying women’s childbirth experiences in the labor–delivery–recovery–postpartum unit (LDRP) unit can help design a peaceful environment. Therefore, this study aimed to evaluate environmental factors influencing women’s childbirth experiences in LDRP unit.

Methods
This qualitative cross-sectional study was conducted on 20 women with a childbirth experience in the LDRP unit. A purposive sampling was performed and continued until data saturation. The data were collected through unstructured interviews and analyzed using inductive content analysis.

Results
Data analysis led to the extraction of three categories: physical security, a meaning-oriented environment, and physical comfort. The physical security category was obtained from three sub-categories: privacy, bed ergonomics, and the possibility of medical interventions. The meaning-oriented environment category was extracted from four sub-categories: promising symbols of becoming a mother, a peaceful environment, and a spiritual environment, and the physical comfort category was extracted from three sub-categories: minimizing noise pollution, ambient lighting, and LDRP internal design.

Conclusions
These study results showed that women’s experience of giving birth in LDRP was accompanied by perceiving physical security, a meaning-oriented environment, and physical comfort. Moreover, the results indicated that the childbirth experience in the LDRP unit might be influenced by physical and emotional environmental factors. Therefore, in order to design a peaceful environment, it is necessary to take into account these factors.
An intergenerational reading of climate change-health concern nexus: a qualitative study of the Millennials’ and Gen Z participants’ perceptions
Authors: Petrescu-Mag Ruxandra Malina , Petrescu Dacinia Crina , Ivan Adrian , Tenter Ancuta 
Published: March 2023

Abstract
Background
The study of climate change through a generational lens is meaningful when one considers the distinct attitudes, behaviors, values, and motivations of each generation. Individuals born between 1980 and 1999, referred to as the Millennial Generation (Millennials) and individuals born up to five years before or after 2000, referred to as Generation Z (Gen Z), may differ widely in their views, values, attitudes, and behaviors. This may lead to conflicts between these two cohorts. As Gen Z enters the labor market, their first-level supervisors will be, in many cases, the Millennials, who may view the topic of climate change-health concern nexus very differently than their Gen Z subordinates. Considering the perspectives of each generation may offer insights on how to engage them to act in an environmentally responsible way to counteract climate change effects.

Objective
The study reveals similarities and differences in how Millennials and Gen Z perceive the climate change-health concern nexus, which illuminates the understanding of the potential generational conflicts and the critical points where intervention is needed.

Method
Interview data from 41 participants were analyzed via thematic analysis using the Quirkos software program. Reporting is in accordance with the COREQ guidelines.

Results
The interview questions elicited responses related to five dimensions: (i) Views of individual and community health; (ii) Knowledge around climate change; (iii) Perceived health impact; (iv) Attitudes towards climate change; (v) Behaviors related to climate change. The findings revealed a set of commonalities and differences in understanding the climate change-health concern nexus between the participants representative of each of the generations examined. One main result is that while most interviewees perceived changes in summer and winter temperatures, they failed to articulate how climate change affected their health.

Conclusion
Thematic analysis revealed that the commonalities of views outweigh the differences between the two generations. A relevant remark is that participants can be described rather as “observers” than “players” since they do not tend to see themselves (through their behavior and their contribution) as active participants in the goal to fight climate change. Consequently, both generations undergo what Stephen Gardiner [1] called “intergenerational buck-passing.”

Abstract
Background and aims
As reported, hypertension (HTN) plays a leading role in explaining mortality worldwide, but it still has many confounding factors. This study explored whether the number of parity and age matters for HTN among couples from the Tehran Lipid and Glucose Study (TLGS).

Methods
This study was conducted on 2851 couples from TLGS. All the variables were collected based on the standard protocol. The participants were categorized into four and five categories according to the number of parity (childless, one, two, three, or more parities) and age (18-30y, 30-40y, 40-50y, 50-60y, and 60-70y), respectively. Spline regression models via log link function for the binary outcome and linear link function for continuous outcomes were applied to evaluate the effect of interaction term age and parity categories on the desired outcome.

Results
Among the total of 2851 pairs, 2.3% had no child, 9.5% had 1 child, 38.4% had 2 children, and 49.8% had ≥ 3 children. The adjusted risk (95% CI) of HTN in females aged 40-50y with 1 child, 2 and ≥ 3 children compared to no child were 1.14(1.04, 1.26), 1.05(1.01, 1.10), 1.12(1.07, 1.17), respectively (p < 0.05). Moreover, in those aged 50-60y with 2 and ≥ 3 children, the risk of HTN significantly increased by 4%. In females aged 60-70y with ≥ 3 children compared to those without children, the risk of HTN increased by 2%. For males aged 30-40y with 2 children compared to the no child group, the adjusted risk of HTN increased by 17%, while for those with ≥ 3 children in the same age group, this risk significantly decreased by 13%. Moreover, in males aged 30-40y with 2 children, risk ratio of HTN increased by 17%, but in males with ≥ 3 children, it decreased by 13% and in those in the same groups but aged 40-50y the risk increased by 6% and 11%, respectively.

Conclusion
Our findings suggest that gender, childlessness, having one child, and multi-parity had different impacts on HTN. Further research is needed to confirm our findings.
