Abstract
Molecular hydrogen is the most abundant molecular species in the universe. While no doubts exist that it is mainly formed on the interstellar dust grain surfaces, many details of this process remain poorly known. In this work, we focus on the fate of the energy released by the H2 formation on the dust icy mantles: how it is partitioned between the substrate and the newly formed H2, a process that has a profound impact on the interstellar medium. We carried out state-of-the-art ab initio molecular dynamics simulations of H2 formation on periodic crystalline and amorphous ice surface models. Our calculations show that up to two-thirds of the energy liberated in the reaction (∼300 kJ mol−1 ∼3.1 eV) is absorbed by the ice in less than 1 ps. The remaining energy (∼140 kJ mol−1 ∼1.5 eV) is kept by the newly born H2. Since it is 10 times larger than the H2 binding energy on the ice, the new H2 molecule will eventually be released into the gas phase. The ice water molecules within ∼4 Å from the reaction site acquire enough energy, between 3 and 14 kJ mol−1 (360–1560 K), to potentially liberate other frozen H2 and, perhaps, frozen CO molecules. If confirmed, the latter process would solve the long standing conundrum of the presence of gaseous CO in molecular clouds. Finally, the vibrational state of the newly formed H2 drops from highly excited states (ν = 6) to low (ν ≤ 2) vibrational levels in a timescale of the order of picoseconds.

Abstract
We present the second dust continuum data release in the Census of High- and Medium-mass Protostars (CHaMP), expanding the methodology trialed in Pitts et al. to the entire CHaMP survey area (280° < ℓ < 300°, − 4° < b < + 2°). This release includes maps of dust temperature (T
d), H2 column density (

), gas-phase CO abundance, and temperature–density plots for every prestellar clump with Herschel coverage, showing no evidence of internal heating for most clumps in our sample. We show that CO abundance is a strong function of T
d and can be fit with a second-order polynomial in log-space, with a typical dispersion of a factor of 2–3. The CO abundance peaks at

d at which this maximal abundance occurs relative to laboratory results is likely due to interstellar UV bombardment in the largest survey fields. Finally, we show that, as predicted by theoretical literature and hinted at in previous studies of individual clouds, the conversion factor from integrated 12CO line intensity (

Abstract
Deep Atacama Large Millimeter/submillimeter Array and Hubble Space Telescope observations reveal the presence of a quenched massive galaxy within the z = 2.91 galaxy group RO-1001. With a mass-weighted stellar age of 1.6 ± 0.4 Gyr this galaxy is one of the oldest known at z ∼ 3, implying that most of its 1011
M
⊙ of stars were rapidly formed at z > 6–8. This is a unique example of the predominantly passive evolution of a galaxy over at least 3 < z < 6 following its high-redshift quenching and a smoking-gun event pointing to the early imprint of an age–environment relation. At the same time, being in a dense group environment with extensive cold gas reservoirs as betrayed by a giant Lyα halo, the existence of this galaxy demonstrates that gas accretion shutdown is not necessary for quenching and its maintenance.
Dark Matter Deficient Galaxies and Their Member Star Clusters Form Simultaneously during High-velocity Galaxy Collisions in 1.25 pc Resolution Simulations

Published: August 2021

Abstract
How diffuse dwarf galaxies that are deficient in dark matter—such as NGC1052-DF2 and NGC1052-DF4—formed remains a mystery. Along with their luminous member globular clusters (GCs), the so-called dark matter deficient galaxies (DMDGs) have challenged observers and theorists alike. Here we report a suite of galaxy collision simulations using the adaptive mesh refinement code Enzo with 1.25 pc resolution, which demonstrates that high-velocity galaxy collisions induce the formation of DMDGs and their star clusters (SCs) simultaneously. With a numerical resolution that is significantly better than our previous study, we resolve the dynamical structure of the produced DMDGs and the detailed formation history of their SCs, which are possible progenitors of the DMDG’s member GCs. In particular, we show that a galaxy collision with a high relative velocity of ∼300 km s−1, invoking severe shock compression, spawns multiple massive SCs

BACKGROUND: Oxidative stress due to free radicals leads to degenerative diseases such as cardiovascular disease. For prevention, high antioxidants food content is needed. AIM: The study aimed to identify the antioxidant activity, proximate compositions, and organoleptic properties of carrot – navel orange marmalade. METHODS: It was an experimental study with five formulations of marmalades, that is, F1 (100 g orange: 0 g carrot), F2 (100 g orange: 25 g carrot), F3 (100 g orange: 50 g carrot), F4 (100 g orange: 75 g carrot), and F5 (100 g orange: 100 g carrot). The organoleptic test assessment was executed through the visual analog scale instrument on hedonic and hedonic quality parameters. The measurement of proximate compositions was conducted according to the Association of Official Analytical Chemists. The carbohydrate was used by difference calculation, while the Brix measured by refractometer. The antioxidant activity was identified by the 1,1-Diphenyl-2-picrylhydrazyl method. RESULTS: The addition of juice and shredded carrot into navel orange marmalade tended to increase organoleptic values. Based on the sensory evaluation, the hedonic value of marmalade F1 had the lowest sensory acceptance value. The marmalade F2 (25% carrot) was dedicated as the most acceptable product with a medium bright color, quite pleasant aroma, a bit sweet, quite thick texture, and overall was quite attractive. Furthermore the carrot added significantly influenced the proximate (carbohydrate, protein, fat, fiber, water, and ash) (p < 0.05) and significantly increased the Brix (p < 0.05). The combination of carrot and orange resulted in a high antioxidant marmalade, with IC50 ranged 16.54 ± 0.02–19.83 ± 0.04 ppm. CONCLUSION: This study revealed that carrot – navel orange marmalade could be a suitable source of antioxidants.

Objective: This study intended to determine visual health of the school children and investigate its relationship with screen time. Methods: This was a school-based cross-sectional study using multistage cluster sampling. A self-reported and interviewer-administered questionnaire were used to compile screen time information. Children presenting visual acuity was evaluated with Snellen chart and non-cycloplegic refraction was performed to those acuities worse than 6/12. Data analysis was performed using SPSS version 22. A p-value ≤0.05 with 95% CI was considered as statistically significant. Results: About 87% children had normal or near normal visual acuity and 13% had visual impairment. The prevalence of refractive error was 22.8%. Astigmatism was the most prevailing type of refractive error, 10%. The children spent on average of 13.82 hours per week on screen time. Television is the most popular electronic devices. Boy spent more time on gaming consoles than girl. There was no statistically significant relationship between refractive error and screen time (p=0.581). Conclusion: The prevalence of refractive error among school children was 23%. The children spent nearly 14 hours per week on screen time. There was no statistically significant relationship between refractive error and screen time. Periodical children vision screening is paramount for early detection of vision impairment and provide possible intervention.
Cutting Edge: CD36 Mediates Phagocyte Tropism and Avirulence of Toxoplasma gondii
Authors: Zhao Yanlin , Reyes Jojo , Rovira-Diaz Eliezer , Fox Barbara A , Bzik David J , Yap George S 
Published: August 2021

Abstract
Resistance and tolerance are vital for survivability of the host–pathogen relationship. Virulence during Toxoplasma infection in mice is mediated by parasite kinase–dependent antagonism of IFN-γ–induced host resistance. Whether avirulence requires expression of parasite factors that induce host tolerance mechanisms or is a default status reflecting the absence of resistance-interfering factors is not known. In this study, we present evidence that avirulence in Toxoplasma requires parasite engagement of the scavenger receptor CD36. CD36 promotes macrophage tropism but is dispensable for the development of resistance mechanisms. Instead CD36 is critical for re-establishing tissue homeostasis and survival following the acute phase of infection. The CD36-binding capacity of T. gondii strains is negatively controlled by the virulence factor, ROP18. Thus, the absence of resistance-interfering virulence factors and the presence of tolerance-inducing avirulence factors are both required for long-term host–pathogen survival.
The Influence of Education and Environment on Patient-Reported Outcome Use in Athletic Training Clinical Practice
Authors: Howard Jennifer S. , Hoch Johanna M. , Tinsley Jennifer , Sciascia Aaron 
Published: August 2021

Context
There have been multiple education reforms aimed at incorporating patient-reported outcome measures (PROMs) into routine clinical care. However, many factors can impact PROM use, including employment setting/policies or access to literature.

Objective
To explore the influence of educational background and employment setting/policies on athletic trainer (AT) attitudes and practices related to PROM use in the secondary and collegiate settings.

Design
Cross-sectional survey.

Setting
Secondary schools; National Collegiate Athletic Association Division I, II, and III; National Association of Intercollegiate Athletics; and junior colleges.

Patients or Other Participants
Five hundred and seven ATs working in secondary and collegiate settings.

Data Collection and Analysis
An established scale evaluating attitudes toward PROMs was distributed to a purposeful sample of 4000 ATs. Also included were questions concerning use of PROMs, employer policies related to PROMs, access to non–National Athletic Trainers' Association (NATA) journals, and educational background. Scores on each scale were compared based on educational background, employment setting/policies, and access to non-NATA scientific journals using Kruskal-Wallis tests with a Bonferroni correction. Frequency of PROM use was evaluated using chi-square tests (α = .05).

Results
PROMs were viewed positively across all participants, with more positive attitudes toward PROMs observed among those with clinical doctorates (P = .029) compared to those with master's or bachelor's degrees and by those with an athletic training-–related postprofessional master's degree (P = .030) compared to a non–athletic training master's degree. There were no differences in attitudes based on timing of professional degree completion. There were no differences in the usage of PROMs based on educational background or employment setting, with only 10% of respondents reporting routine PROM use. However, access to non-NATA scientific journals (P = .016) and employer policies related to the use of PROMs were associated with increased use of PROMs (P &lt; .001).

Conclusion
Educational reforms have enhanced the attitudes of practicing ATs toward PROMs; however, environmental facilitators, such as expanded access to scientific literature and policies regarding the use of PROMs, are necessary to increase the use of PROMs.

Published: August 2021

Abstract
Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is a B-cell lymphocytic neoplasm with indolent clinical course. If identified early, observation is opted. Many variables lead to the initiation of treatment. Authors describe a 62-year-old male presenting with shortness of breath and found to have white cell count of 1360 × 109/L and subsequently was diagnosed with CLL/SLL. The patient received leukapheresis along with tumor lysis treatment and systemic chemotherapy with fludarabine, cyclophosphamide, and rituximab regimen. His course was complicated with deep venous thrombosis, extensive cutaneous, and sinus mucosa involvement by CLL/SLL. The patient clinically improved and on follow-up clinic visits documented normalization of his white cell counts. The case report brings up a rare presentation of CLL/SLL with such an extreme high white cell count, leukostasis symptoms and extramedullary involvement of disease and encourages providers to be vigilant of rare presentation of CLL/SLL.
Influence of Intestinal Helminth Burden on Clinical Manifestations, Therapeutic Response, and Leishmania braziliensis Load in Patients with New World Cutaneous Leishmaniasis

ABSTRACT.
Leishmania braziliensis is the most important cause of cutaneous leishmaniasis (CL) in the Americas. A Th1-type immune response is required to control Leishmania infection, but an exaggerated inflammatory response leads to the development of ulcers seen in CL. Infection with intestinal helminths has the potential to inhibit the Th1 response in a manner that depends both on the species of helminth present as well as the burden of helminthiasis. We conducted a prospective cohort study of CL patients from an endemic area between January and December 2017 with either negative or high intestinal helminth burden to characterize relationships between helminth burden, L. braziliensis quantification within CL lesions, clinical aspects of CL, and therapeutic response. Of 234 participants with leishmaniasis who underwent stool examination at the time of diagnosis, 45% had detectable helminth infection. The overall cure rate after 90 days was 66%, with a median time to resolution of disease of 40 days (interquartile range: 30–65 days). There was no significant association between the type of helminth infection or the magnitude of intestinal helminth burden at the time of diagnosis and L. braziliensis genomic DNA (gDNA) detected in biopsies from CL lesions. Likewise, there was no association between helminth burden and response to treatment after 90 days. Considering quantification of parasite DNA in CL lesions, participants who were cured at 90 days had a median of 0.017 ng/mg gDNA, and participants who failed therapy had a median of 0.091 ng/mg gDNA (P = 0.03). The results indicate that cutaneous Leishmania load may influence therapeutic response in CL.

Authors: Mammeri M. 
Published: August 2021

In the theoretical research of chaotic dynamical system, the different type of bifurcations is a very interesting powerful tool for analyzing the qualitative behavior of chaotic dynamical system; this short paper is devoted to analysis of a simple 2-D symmetry discrete chaotic map with quadratic and cubic nonlinearities. The dynamical behaviors of the map are investigated by mathematical analysis and simulated numerically using package of Matlab . We compute numerically the bifurcation diagram and largest Lyapunov exponent and phase portraits. The research results indicate that there are interesting nonlinear physical phenomena in this simple 2-D symmetry discrete cubic map, such as symmetry bifurcation, Hopf bifurcation, symmetry breaking bifurcation and identical symmetric attractors. The important nonlinear physical phenomena obtained in this paper would benefit the study of the cubic chaotic map and the development of the theory of chaotic discrete dynamical systems.

Published: August 2021

Abstract
Importance: Occupational performance limitations (OPLs) are poorly understood sequelae of concussion. This study aimed to establish the need for occupational therapy services for people who have sustained a concussion and to support the profession’s role in facilitating occupational performance for college students experiencing signs and symptoms after concussion.
Objective: To describe the types and frequency of, and assess risk factors for, OPLs in college students after concussion.
Design: Cross-sectional descriptive study.
Setting: Web-based survey on Qualtrics.
Participants: A total of 220 participants completed the survey; of those, 52 (23.6%) self-identified as having sustained a concussion and were further asked about OPLs after the concussion.
Results: Eighty-nine percent (n = 46) of the participants reported an OPL in at least one area, and higher OPL scores were associated with the number of concussion symptoms (r = .34, p = .02) and increased recovery time (≥3 days vs. &lt;3 days, p = .006).
Conclusions and Relevance: College students reporting concussions with more symptoms that persisted for longer periods were more likely to experience occupational performance loss. Frequent OPLs were reported in occupations associated with the participants’ primary role of student. These results indicate a unique need for occupational therapy intervention with students to facilitate their continued success in academic pursuits.
What This Article Adds: People who have sustained a concussion experience OPLs. Occupational therapy has a role in facilitating a return to occupational performance during recovery, especially in helping college students with concussion return to the classroom.
