Makeup Water Addition Can Affect the Growth of Scenedesmus dimorphus in Photobioreactors

Makeup water constitutes a key component in the water management of microalgal cultivation systems. However, the effect of makeup water addition on microalgal growth remains largely unexplored. This study compared two deionized water addition intervals (1 day and 4 days) for their effect on the growth of Scenedesmus dimorphus (S. dimorphus hereafter) in 2000 mL Pyrex bottles under controlled conditions. Cell counts and dry algal biomass (DAB) were measured to characterize the microalgal growth rate. Water addition intervals impacted algal cell counts but had little effect on DAB. Adding makeup water every day resulted in a higher growth rate (8.80 ± 1.46 × 105 cells mL−1 day−1; p = 0.22, though) and an earlier occurrence of the peak cell count (day 9) than adding it every 4 days (6.95 ± 1.68 × 105 cells mL−1 day−1 and day 12, respectively). It is speculated that water loss over an extended period and the following makeup water addition posed stress on S. dimorphus. Surpassing the peak cell count, S. dimorphus continued to grow in DAB, resulting in an increased cell weight as a response to nutrient starvation. Optical density at 670 nm (OD670) was also measured. Its correlation with DAB was found to be affected by water addition intervals (R2 = 0.955 for 1 day and 0.794 for 4 days), possibly due to a water loss-induced change in chlorophyll a content. This study is expected to facilitate the makeup water management of photobioreactor and open pond cultivation systems.
Prevalence of ocular findings and their association with glycemia in dogs with diabetes mellitus: A 10-year clinical study (2009–2019)

Background: Although ocular findings in diabetic patients are well described, prevalence data for those is unknown. Aim: To describe the prevalence of ocular findings and their association with glycemia in dogs with diabetes mellitus. Methods: Medical records from diabetic dogs assessed by the ophthalmology and the internal medicine services at the Veterinary Teaching Hospital of the Autonomous University of Barcelona were reviewed (2009–2019). Results: Seventy-five dogs (150 eyes) of both genders (51/75 females; 68% and 24/75 males; 32%) and a mean age of 9.37 ± 2.43 years, were included. The most common ocular findings were cataracts (146/150; 97.3%), vitreous degeneration (45/98; 45.9%), anterior uveitis (47/150; 31.3%), aqueous deficiency dry eye (ADDE) (33/150; 22%), diffuse corneal edema (31/150; 20.7%), non-proliferative retinopathy (13/98; 13.3%), and lipid keratopathy (9/150; 6%). The most prevalent type of cataracts observed (78/146; 53.4%) was intumescent, which was commonly accompanied by non-proliferative retinopathy (p = 0.003). Among the diabetic dogs, blood glucose levels were statistically higher in dogs with non-proliferative retinopathy or anterior uveitis (p < 0.005). Conclusions: Ocular complications of diabetes mellitus in dogs are numerous, being the most frequent intumescent cataracts, vitreous degeneration, anterior uveitis, ADDE, diffuse corneal edema, and non-proliferative retinopathy. This high prevalence warrants a more detailed ophthalmic evaluation in diabetic dogs especially for those undergoing cataract surgery. Furthermore, a predisposition for anterior segment inflammation and non-proliferative retinopathy is suggested when fasting plasma glucose is higher than 600 mg/dl.
Electroantennogram and behavioural responses of Plutella xylostella to volatiles from the non‐host plant Mentha spicata

Plutella xylostella Linnaeus (Lepidoptera: Plutellidae) is one of the most important pests of cruciferous vegetables. Mechanically damaged Mentha spicata Linnaeus (Lamiales: Lamiaceae) strongly repels P. xylostella adults; however, the repellent mechanism remains unclear. In this study, the repellent mechanism was explored based on the electroantennogram (EAG) and behavioural responses of P. xylostella to volatiles from the damaged M. spicata. First, the active volatile compounds in the headspace volatiles of damaged M. spicata were identified by gas chromatography‐electroantennographic detection (GC‐EAD) and gas chromatography–mass spectrometry (GC–MS). Furthermore, the EAG and behavioural responses of P. xylostella to these compounds were investigated. The GC‐EAD results indicated that four compounds, 2,4‐dimethylheptane, 4‐methyloctane, 2‐methylnonane, and myrcene induced EAG responses in female antennae. 2‐methylnonane and myrcene elicited strong dose‐dependent EAG responses starting at a dose of 1 μg/μL. Choice tests in a four‐arm olfactometer showed significant repellent effects of the four compounds on P. xylostella adults at 100 μg/μL, and the repellent indices of 2,4‐dimethylheptane, 4‐methyloctane, 2‐methylnonane, and myrcene were 70.0%, 76.7%, 66.7%, and 73.3% to mated females, respectively. Finally, oviposition repellence assays showed that female adults were significantly repelled by these compounds, and the oviposition repellent index for myrcene was 23.9%. 2,4‐dimethylheptane, 4‐methyloctane, 2‐methylnonane, and myrcene mediate the repellence of wounded M. spicata to P. xylostella adults, suggesting that the four compounds contribute towards developing behavioural regulators of this important pest.
COHOMOLOGY OF GROUPS AND TRANSFER

The purpose of this paper is to show how the transfer (Verlagerung) of a group A into a subgroup B of finite index can be obtained and generalized in the framework of the cohomology theory of groups (cf. [3]1) and of abstract complexes over a ring [2]. The generalized transfers are homomorphisms of the cohomology groups of the subgroup B into those of the group A; they are in general nontrivial and related in a simple way to the restriction homomorphism of the cohomology groups of A into those of B. The situation in which they come up quite naturally is that of a complex over a ring R considered as a complex over a subring S of R; the existence of these homomorphisms as well as their main properties follow very easily from the concepts and methods used in this connection in algebraic topology for the relations between the fundamental group and the homology structure of a space (cf. [3, 2]). The topological meaning of the transfers is not mentioned in this note; it will be studied elsewhere in a more general context, including other topological and algebraic applications.2 In ? 1 we give a brief account of the theory of complexes over a ring and of acyclic complexes. 2 contains the definitions and main theorems in the general situation of complexes over rings mentioned above; they are all based upon the following simple but fundamental result': If C is a complex over the ring R, Cs the same complex considered over a subring S of R, J an S-module, I the group of all S-homomorphisms of R into J (I is an R-module), then there is a natural isomorphism between the (equivariant) cohomology groups H(es , J) Hp(e, I). In ? 3 we consider a group A and a subgroup B and apply ? 2 to the case where R = RA, the integer group ring of A, and S = RB, and where e is free and acyclic. The cohomology groups of e are then the "cohomology groups of A", H'(A, J), and those of Cs the groups HP(B, J); the above result gives the isomorphism HP(B, J) _ HY(A, I). If J is an RA-module, and if the index n of B in A is finite, a certain RA-homomorphism t of I into J is considered; it induces a homomorphism of HP(B, J) into HI(A, J), for any p _ 0, called transfer of B into A. If, as usual, the groups HP(A, J) and HP(B, J) are described by means of cochains which are functions of several variables in A (in B) with values in J, the transfer can be given by an explicit cochain map ? of B into A (cf. 3.3,
A Longitudinal Pilot Study of Stress and Sleep in First-Year Osteopathic Medical Students

OBJECTIVE Poor sleep quality is thought to be a contributor to medical student stress. The authors evaluated the effect of high and low periods of academic stress on sleep quality and quantity in first-year medical students. METHODS A group of 25 students in their first year of medical school were provided Fitbit Charge 3 activity trackers for continual use and were surveyed at 4 intervals to assess stress level, sleep quantity, and sleep quality. Fitbit data were collected through the Fitbit mobile app and uploaded to the Fitabase (Small Steps Labs, LLC) server. Data collection times were scheduled around the academic exam schedule. Weeks in which testing occurred were identified as high-stress periods. Results from assessments were compared to nontesting periods of low stress. RESULTS During stressful periods, students slept an average of one hour less per 24-h period, took more naps, and reported poorer sleep quality than during the low-stress periods. No significant change was seen in the 4 surveyed intervals in sleep efficiency or sleep stages. CONCLUSION Students slept less and had poorer quality sleep in their main sleep event during stressful periods but attempted to compensate with increased napping and weekend catchup sleep. The objective Fitbit activity tracker data were consistent with and validated the self-reported survey data. Activity trackers could potentially be used to optimize the efficiency and quality of both student napping and main sleep events as one component of a stress reduction program for medical students.
The Theory of Simple Rings

1. Vector spaces over rings. If R is a ring, we call a set V of elements an R-vector space if its elements form an abelian group under addition and if R is an operator domain on this abelian group, satisfying the usual axiomsnamely the distributive law and the condition that multiplication in the ring is the same as combination of operators. Usually R operates on the left side, and in that case the product of operators corresponds to the function-theoretic product (0-T (x) = o(r (x))) ; but occasionally we write the operators on the other side, and then this is not true. In the following, we shall usually assume that no non-zero vector is annihilated by every element of R. The only spaces we shall consider will be R-subspaces. A space is said to satisfy the minimal condition if any set of R-subspaces contains a smallest one. This is equivalent to the descending chain condition; that is, to the condition that every descending chain of subspaces must be finite. The minimal condition on spaces is occasionally easy to verify by the following:
Leucyl and Cystinyl Aminopeptidase as a Prognostic-Related Biomarker in OV Correlating with Immune Infiltrates

Background It was indicated that tumor intrinsic heterogeneity and the tumor microenvironment (TME) of ovarian cancer (OV) influence immunotherapy efficacy and patient outcomes. Leucyl and cystinyl aminopeptidase (LNPEP) encodes a zinc-dependent aminopeptidase, which has been proved to participant in the vesicle-mediated transport and class I MHC mediated antigen processing and presentation. However, the function of LNPEP in TME of OV and its potential molecular mechanisms have not been determined. Therefore, we aimed to investigate a prognostic biomarker which may be helpful in identifying TME heterogeneity of ovarian cancer. Methods In this study, bioinformatics databases were used to explore the expression profile and immune infiltration of LNPEP. Bioinformatics analyses of survival data and interactors of LNPEP were conducted to predict the prognostic value of LNPEP in OV. The protein levels of LNPEP were validated by Western blot and immunohistochemistry. Results Based on the TCGA data, our data displayed that the mRNA expression of LNPEP was markedly down-regulated in ovarian cancer than that in para-cancer tissues, contrary to the protein level. Importantly, high LNPEP expression was associated with poor prognosis in patients with OV. Furthermore, Cox regression analysis showed that LNPEP was an independent prognostic factor in OV. GO and KEGG pathway analyses indicated the co-expressed genes of LNPEP were mainly related to a variety of immune-related pathways, including Th1 and Th2 cell differentiation, Th17 cell differentiation, and immunoregulatory interaction. Our data also demonstrated that the expression of LNPEP was strongly correlated with immune infiltration levels, immunomodulators, chemokines and chemokine receptors. Conclusion In our study, we identified and established a prognostic signature of immune-related LNPEP in OV, which will be of great value in predicting the prognosis of clinical trials and may become a new therapeutic target for immunological research and potential prognostic biomarker in OV.
General versus Neuraxial Anesthesia on Clinical Outcomes in Patients Receiving Hip Fracture Surgery: An Analysis of the ACS NSQIP Database

Whether the use of neuraxial anesthesia or general anesthesia leads to more favorable postoperative outcomes in patients receiving hip fracture surgery remains unclear. We used data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Data Files between 2016 and 2020 to investigate the association of neuraxial anesthesia and general anesthesia with morbidity and mortality after hip fracture surgery. Inverse probability of treatment weighting (IPTW) was used to balance the baseline characteristics, and multivariable Cox regression models were used to estimate the hazard ratio (HR) with a 95% confidence interval (CI) for postoperative morbidity and mortality among the different anesthesia groups. A total of 45,874 patients were included in this study. Postoperative adverse events occurred in 1087 of 9864 patients (11.0%) who received neuraxial anesthesia and in 4635 of 36,010 patients (12.9%) who received general anesthesia. After adjustment for IPTW, the multivariable Cox regressions revealed that general anesthesia was associated with increased risks of postoperative morbidity (adjusted HR, 1.19; 95% CI, 1.14–1.24) and mortality (adjusted HR, 1.09; 95% CI, 1.03–1.16). The results of the present study suggest that, compared with general anesthesia, neuraxial anesthesia is associated with lower risks of postoperative adverse events in patients undergoing hip fracture surgery.
Gross Morphological and Histological Features of Larynx in Yankasa Sheep ‎‎(Ovis aries)‎

The present study, conducted on the larynx of five adult Yankasa sheep of local breed, aimed at exploring its basic anatomy and histological features. The larynx consists of four cartilages; the unpaired epiglottis rostroventral, unpaired thyroid ventrally, dorsal paired arytenoid, and caudal unpaired cricoid. These cartilages presented distinct morphological features and were connected to each other by ligaments. The intrinsic laryngeal muscles include; the dorsal cricoarytenoid and transverse arytenoid muscles. The lateral cricoarytenoid was concealed by the thyroid laminae. The ventrally located thyroarytenoid and cricothyroid muscles. The laryngeal cavity comprised of rostral vestibule, a narrow middle glottic cleft and a wide infraglottic cavity caudally. Histologically, the epiglottis was lined by stratified squamous keratinized epithelium, the thyroid cartilage was lined by pseudostratified columnar epithelium, whereas the arytenoid cartilage was lined by pseudostratified columnar ciliated epithelium with goblet cells. The loose irregular loose connective tissue of the propria submucosa comprised of connective tissue cells mainly fibroblast, and fine blood capillaries, whereas the deeper part presented glandular tissues, ducts, fat cells and cartilages. It is envisaged that the study has provided basic information on gross and histological feature of the larynx in the Yankasa sheep.
Global well-posedness of a haptotaxis model with spatial and age structure

A system of non-linear partial differential equations modeling tumor invasion into surrounding healthy tissue is analyzed. The model incorporates haptotaxis, i.e., the directed migratory response of tumor cells to the extracellular environment, as well as spatial and age structure of the tumor cells. Global existence and uniqueness of nonnegative solutions is shown.
Religious Coping Strategies For Nurses’ Work Related Stress: A Scoping Review

<div><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td align="left" valign="top"><p><em>Stress was recognized internationally as a work hazard for nurses</em><em>, but e</em><em>ffective coping can prevent work stress. Religious coping is the type of emotional coping that </em><em>is </em><em>widely used by nurses. A compilation of studies related to the role of religious coping in nurses’ </em><em>work-related</em><em> stress is still limited. The purpose of this scoping review is to determine the use of religious coping</em><em> technique</em><em> in nurses and its impact on stress. Methods: This scoping review was carried out following the PRISMA Statement recommendations checklist, Items for Systematic Reviews, and Meta-Analyses—Extension for Scoping Reviews (PRISMA-SCR). Databases for literature searching were SCOPUS, Springer Link, and Science Direct. The search strategy was (nurse or nursing) and (religious or spiritual) and coping and (job stress or work stress or occupational stress). Only original research articles, published within the last 10 years, in English or Indonesian, free full</em><em>-</em><em>text availability</em><em>, and focusing on nurses’ religious coping synthesized by the authors</em><em>.

Future research needs to analyze how the types of stressors and religiosity affect religious coping. </em></p><p> </p></td></tr></tbody></table></div><p><strong><em>Keyword:</em></strong> <strong><em>Nurse, Religious Coping, Work Stress</em></strong></p>
Student Attitudes Towards Distance Learning at a Large Urban Public College

Student attitudes towards distance learning can affect both the acquisition of knowledge and the motivation to learn. This study explores student attitudes towards the following four topics: (1) technological and environmental impediments towards distance learning, (2) asynchronous vs. synchronous course preferences, (3) online vs. in-person course preferences, and (4) attitudes towards taking online courses in the future. The findings of the study are based on two anonymous online surveys conducted in the spring and fall of 2020 among students at a large urban public college located in the Northeast U.S. The study reveals that a significant number of students have unreliable Internet and live in homes not conducive for online learning. By a narrow margin, students prefer an asynchronous to a synchronous approach to online learning. Along several dimensions covering different facets of the classroom experience, students prefer in-person courses to online courses. The disparities favoring in-person classes are most noticeable with respect to the ability to concentrate in class sessions, feeling motivated to learn, and developing friendship ties with classmates. Distinctive profiles exist among students who opt for these different teaching modalities. Those students who are more positively disposed towards in-person classes tend to be younger, freshmen or sophomores, those experiencing higher stress levels, and those whose physical arrangements at home are not conducive for learning. Importantly, though, a majority of students say they were inclined towards taking more online course in the future.
The Role of Gratitude in a Positive Psychology Group Intervention Program Implemented for Undergraduate Engineering Students

Over the past decades, research on positive psychology for building strengths has proliferated. The present study aimed to explore the effect of gratitude in a 5-week positive psychology group program for undergraduate engineering students which included an intermediary 2-week gratitude intervention. In a mixed-design, 69 students from three engineering departments of the School of Pedagogical and Technological Education (ASPETE), assigned to the intervention (N = 34) and the control group (N = 35), with an average age of 21.52 years (SD = 4.63), were administered the Gratitude Questionnaire—six item form (GQ-6), the Modified Differential Emotions Scale (mDES), the Connor–Davidson Resilience Scale (CD-RISC), the Subjective Happiness Scale (SHS), and the Life Orientation Test—Revised (LOT-R). The condition experimental vs. control group was designated as the between-subjects factor, and time, that is, baseline vs. post intervention, was set as the within-subjects factor. Students who received the intervention reported significantly higher levels of gratitude. The increase in gratitude was due to the positive psychology group program. In addition, gratitude showed a significant effect on happiness and optimism, but failed to attain a significant impact on positive and negative emotions and resilience. Further research is needed to elucidate the effectiveness of positive psychology programs for undergraduate engineering students and the intervening cognitive processes.
Root Growth and Defense Response of Seedlings against Fusarium oxysporum in Sand Culture and In Vitro—A Comparison of Two Screening Approaches for Asparagus Cultivars

Two rapid asparagus (Asparagus officinalis L.) screening methods, in sand culture and in vitro, were tested to evaluate the response of young seedlings against F. oxysporum f. sp. asparagi (isolate Foa1). Root morphological parameters were evaluated and correlated with the symptomatology and expression of the defense-related genes at 5 and 7 dpi. In sand cultivation, the Foa1-inoculated cultivars showed no visible disease symptoms on their roots until 7 dpi. Two-factorial ANOVA statistics found no significant interaction between the cultivars and treatments for most root parameters but some differences between the cultivars. The in vitro Foa1-inoculated cultivars showed high susceptibility according to their symptomatology and differed greatly in the length of the primary root at 5 dpi. In some cultivars, the primary root length and root surface area were higher upon Foa1 inoculation. The expression changes were very different among the cultivars, with significant induction of PR1, POX, and PAL at 5 dpi in all cultivars in vitro but only in two cultivars in sand cultivation. The in vitro screening method, although more artificial, seemed to be more reliable than sand cultivation since the fungus was able to develop well in the culture medium. In sand-filled pots, the fungus may have been hindered in its development, even though a considerable higher amount of Foa1 was inoculated. In addition, the fungal growth was easily trackable in tubes, while in sand cultivation, the results were only visible after pulling the seedlings out of the pots 12 dpi.
