Abstract
Background
The association between different dietary approaches and quality of life (QoL) has been well-demonstrated in previous research. However, the relationship between glycemic index (GI) and glycemic load (GL) with different dimensions of QoL has not been established. Therefore, we aimed to investigate the relationship between GI and GL with QoL in overweight and obese women.

Methods
Two hundred seventy-six overweight and obese women (body mass index (BMI) ≥ 30 kg/m2), aged 18–64 years old, were included in this cross-sectional study. The amount of dietary intake and GI and GL indexes were established using a valid and reliable Food Frequency Questionnaire (FFQ) containing 147 items. Body composition (using bioimpedance analysis), anthropometrics, and physical activity were assessed. Insulin resistance (HOMA-IR) and hs-CRP were also measured, whilst QoL was measured using the SF-36 (short-form-36), self-administered, questionnaire.

Result
Analyses were performed using multivariable linear regression, considering a wide range of confounding variables, such as age, physical activity, BMI, education, job, smoking, and marriage. We found a significant negative association between glycemic load and quality of life (β = -0.07, 95%CI = -0.13_ -0.01, p = 0.01). No significant associations were observed between glycemic index and quality of life (β = -0.03, 95%CI = -0.81_ 0.75, p = 0.93).

Conclusion
We observed a significant negative association between QoL and GL, but not GI, among overweight and obese women in Iran. Our results need to be confirmed with further well-designed and adequately powered studies that control for clinical confounders.

Published: February 2023

Abstract
Background
World is currently challenging with Covid-19 pandemic. Nutritional status is a determinant factor in the treatment process and recovery for patients with Covid-19. Although a limited data is available about the effects of nutrition on this disease. Therefore, the aim of this study was to identify nutritional problems in patients recovering from Covid-19 before, during and after the disease.

Methods
This qualitative descriptive study was carried out based on the specified inclusion criteria through targeted sampling of 45 patients recovered from Covid-19, 2021–2022. In-depth semi-structured individual interviews were used to collect data. Interviews were recorded, transcribed and analyzed using qualitative content analysis method and MAXQDA Software.

Results
Based on the participants’ description of this stage, it can be reported that most of the individuals who were infected had no specific symptoms. Nutrition-linked problems in the main stage of the disease included troubles in tolerating foods and nutrition (e.g., fatty and solid foods), highly consumed foods in the main stage of the disease (e.g., beverages), individuals’ approaches to improve nutritional challenges (e.g., consumption of herbal teas and soft texture foods) and using supplements. The patients stated fewer nutritional problems after recovering from the disease. The most significant change included their desire to eat solid foods such as rice, bread, pasta and fast foods.

Conclusion
appropriate nutrition with medication can help accelerate the recovery process of the patients, especially hospitalized patients with further severe degrees of the illness.
Gelatin methacryloyl (GelMA) loaded with concentrated hypoxic pretreated adipose-derived mesenchymal stem cells(ADSCs) conditioned medium promotes wound healing and vascular regeneration in aged skin

Abstract

Background
Aging skin is characterized by a disturbed structure and lack of blood supply, which makes it difficult to heal once injured. ADSCs secrete large amounts of cytokines, which promote wound healing and vascular regeneration through paracrine secretion, and the number of cytokines can be elevated by hypoxic pretreating. However, the components of ADSCs are difficult to retain in wounds. Gelatin methacrylate (GelMA) is a photopolymerizable hydrogel synthesized from gelatin and has recently emerged as a potentially attractive material for tissue engineering applications. GelMA loaded with concentrated hypoxic pretreated ADSCs conditioned medium could provide a new method of treating wounds in aged skin.

Methods
Primary ADSCs were isolated from human adipose tissue and characterized by flow cytometry and differentiation test. ADSCs in passages 4-6 were pretreated in the hypoxic and normoxic environments to collect conditioned medium, the conditioned medium was then concentrated to prepare concentrated ADSCs conditioned medium(cADSC-CM)(the one collected from ADSCs under hypoxia was called hypo-CM, and the one from normoxia was called nor-CM). The concentration of cytokines was detected. After treated with cADSC-CM, the abilities of proliferation, migration, and tube formation of human umbilical vascular endothelial cells (HUVECs) were assayed, and Akt/mTOR and MAPK signal pathway was detected using western blotting. GelMA+hypo-CM hydrogel was prepared, and a comprehensive evaluation of morphology, protein release efficiency, degradation rate, mechanical properties, and rheology properties were performed. Full-thickness skin wounds were created on the backs of 20-month-old mice. After surgery, GelMA, GelMA+F12, GelMA+hypo-CM, and GelMA+nor-CM were applied to the wound surface respectively. H&E, Masson, and immunohistochemistry staining were performed, and a laser Doppler perfusion imager was used to evaluate the blood perfusion. The student’s t-test was used for analysis between two groups and a one-way analysis of variance (ANOVA) was used for analysis among multi groups.

Results
Our results revealed that 1) wounds in aged skin healed more slowly than that in young skin and exhibited poorer perfusion; 2) hypoxic pretreated ADSCs secreted more cytokines including VEGF by activating HIF1α; 3) hypo-CM promoted proliferation and migration of HUVECs through VEGF/Akt/mTOR and MAPK signal pathway; 4) GelMA-hypoCM accelerated wound healing and angiogenesis in aged skin in vivo.

Conclusion
GelMA loaded with concentrated hypoxic pretreated adipose-derived mesenchymal stem cells conditioned medium could accelerate wound healing in aged skin by promoting angiogenesis.

Published: February 2023

AbstractReproductive biology is an important topic that is well explored in many vertebrates, but information about frogs’ reproductive mechanisms could be improved. Therefore, this review aims to provide organized and specific information on frog reproduction. First, we developed schemes that illustrate the general information regarding reproductive biological mechanisms in frogs in a specific way. Then, we described the physiological, histological, and morphological mechanisms of each organ of the reproductive system of male and female frogs. Finally, this manuscript may contribute to a broader understanding of anuran reproductive biology. Since, understanding frogs’ reproductive system permits one to make a comparison with reproduction with other anurans.
Congressional symmetry: years remaining mirror years served in the U.S. House and Senate
Authors: Carey James R. , Eriksen Brinsley , Rao Arni S. R. Srinivasa 
Published: February 2023

AbstractOur overarching goal in this paper was to both test and identify applications for a fundamental theorem of replacement-level populations known as the Stationary Population Identity (SPI), a mathematical model that equates the fraction of a population age x and the fraction with x years to live. Since true stationarity is virtually non-existent in human populations as well as in populations of non-human species, we used historical data on the memberships in both chambers of the U.S. Congress as populations. We conceived their fixed numbers (e.g., 100 Senators; 435 Representatives) as stationary populations, and their years served and years remaining as the equivalent of life lived and life remaining. Our main result was the affirmation of the mathematical prediction—i.e., the robust symmetry of years served and years remaining in Congress over the approximately 230 years of its existence (1789–2022). A number of applications emerged from this regularity and the distributional patterns therein including (1) new metrics such as Congressional half-life and other quantiles (e.g., 95% turnover); (2) predictability of the distribution of member’s years remaining; (3) the extraordinary information content of a single number—the mean number of years served [i.e., derive birth (b) and death (d) rates; use of d as exponential rate parameter for model life tables]; (4) the concept of and metrics associated with period-specific populations (Congress); (5) Congressional life cycle concept with Formation, Growth, Senescence and Extinction Phases; and (6) longitudinal party transition rates for 100% Life Cycle turnover (Democrat/Republican), i.e., each seat from predecessor party-to-incumbent party and from incumbent party-to-successor party. Although our focus is on the use of historical data for Congressional members, we believe that most of the results are general and thus both relevant and applicable to all types of stationary or quasi-stationary populations including to the future world of zero population growth (ZPG).

Published: February 2023

Abstract
Background
Spontaneous bacterial peritonitis (SBP) is a significant complication among cirrhotic patients with ascites and is associated with high mortality. Early diagnosis and treatment of SBP are crucial, as they are associated with better outcomes and lower mortality. The neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) are routine, inexpensive, easily measured markers readily obtained from a complete blood count (CBC). Several studies have addressed the diagnostic role of NLR and MPV in patients with SBP but with different cutoff values, sensitivity, and specificity. Therefore, we conducted this study to validate the clinical utility of NLR and MPV in diagnosing SBP.

Methods
This study included 332 cirrhotic patients with ascites who were admitted to Sohag University Hospitals in Egypt between April 2020 and April 2022. Of these patients, 117 had SBP, and 215 did not. Both NLR and MPV were measured in all patients, and the ability of NLR and MPV to diagnose SBP was assessed using the receiver operator characteristic (ROC) curve analysis.

Results
NLR and MPV were significantly elevated in patients with SBP compared to those without SBP (P < 0.001). At a cutoff value of 5.6, the sensitivity and specificity of the NLR in detecting SBP were 78% and 81%, respectively. In contrast, MPV, at a cutoff value of 8.8 fL, had a sensitivity of 62% and a specificity of 63%. The combination of NLR and MPV did not provide significant additional diagnostic value beyond only using NLR.

Conclusion
Although NLR and MPV allow the detection of SBP, the NLR has higher clinical utility and is superior to MPV in diagnosing SBP.
How to Read The Pentagon Papers
Authors: Puckett Kent 
Published: February 2023

Abstract
This essay understands what it meant and what it means to read The Pentagon Papers in a few related ways. First, when it appeared in 1971, there were at least three different versions of the Papers available. Because, in other words, the reader had to choose between versions from the very start, The Pentagon Papers had to be read both as a text and as a textual event. Second, although the Papers are often remembered as an unmediated document dump, the whole was, in fact, a highly mediated and intensely narrative document, an effort to present the incoherent story—the violence—of Vietnam as a coherent discourse. As a result, they not only demand but also assume interpretation. Finally, the fact that Leslie Gelb, the Department of Defense editor of the Papers, officially introduced its more than seven thousand pages with a pointed reference to Moby-Dick encourages us to look for and to understand how something unexpectedly novelistic supports and maybe subverts the documentary force of The Pentagon Papers.
Open-Circuit Narrative: Programmed Reading in Richard Powers
Authors: Stewart Garrett 
Published: February 2023

Abstract
Long before the eight-stranded weave of ecocritical plot in Richard Powers's Pulitzer Prize–winning The Overstory (2018) and, since then, the interlace between inset astrobiological bedtime stories and the environmentalist passions of family psychodrama in his Booker-nominated Bewilderment (2021), an important turn-of-the-millennium work by this MacArthur-lauded novelist, Plowing the Dark (2000), remains his most strenuous venture in what this article calls the open-circuit structure of his typical multi-plot narratives. Scenes of secretly funded VR aesthetics in the high-tech America of “research and development” are pitted against the contrasting affect, emphatically detached in space and time, of savage sensory deprivation suffered by an Arab American US citizen as jihadist prisoner in Beirut. Only at the eleventh hour of plot time is this man's plight revealed, by proximate cause, to render him, in retrospect, the indirect victim (spoiler alert) of electronic sophistication in American's “wired wars.” Until then, reading swerves between alternate and seemingly unrelated spaces of cyber-optic volatility and cognitive evacuation, virtual over against vitiated—with an all-too-real network of violence hard-wiring them imperceptibly to each other. Beyond the latent dialectic of these disjunct prose episodes, the novel critiques a world “formed” on quite different principles, whose geopolitical systems it confronts on fiction's own resistant verbal terms. To argue the contrary—that literary and societal forms are different from each other only in degree or scale—is, in an especially leveling sense, to rescind crucial differences between the force of depiction and world of force, which every lucid nuance of Powers's unique narrative style would resist.
Keeping Quiet in Tove Jansson's Fair Play
Authors: Yamaguchi Liesl 
Published: February 2023

Abstract
As a follow-up to the Common Knowledge symposium “Apology for Quietism” (15:1 to 16:3), this guest column asks what it means to say nothing. Strictly speaking, to “say nothing” is a contradiction in terms (unless, of course, one says “Nothing,” which is another thing entirely and generally not nothing). This essay explores what it means to say nothing in Tove Jansson's novella Fair Play (first published in Finland Swedish as Rent spel, 1989), an episodic account of the intertwined lives of two elderly artists. Through its careful staging of saying nothing, the text calls attention to the many vital functions that silence serves: exposing tacit expectations, opening up creative and psychological space, enabling otherwise impossible relations. Bringing forth the diversity, complexity, and mystery behind hesitation and reticence, Jansson's novella emerges here as a quiet celebration of conversational practices associated with weakness, redefining the genre of the “love story” along the way.
Contingency All the Way Up
Authors: Mutter Matthew 
Published: February 2023

Abstract
This review-essay examines two books about the history of the modern humanities: Permanent Crisis: The Humanities in a Disenchanted Age by Paul Reitter and Chad Wellmon and Battle of the Classics: How a Nineteenth-Century Debate Can Save the Humanities Today by Eric Adler. Both studies reconstruct genealogies of discourse and practice by which to understand the “crisis” of the humanities, yet they draw disparate lessons from these reconstructions. The review traces the two monographs’ competing accounts of the historical continuity of humanities practices and the moral dimension of humanistic inquiry. Together, Permanent Crisis and Battle of the Classics describe an antinomy that can be neither resolved nor ignored: the methodological norms of the modern university tend to subvert the humanities’ investment in meaning and value, but without that investment, humanistic study loses the motivations and purposes that define it.
Rereading a Poetics of Divination: Oracular Visuality and Iterations of Landscape in Wei-Jin Lyricism
Authors: Noel Thomas Donnelly 
Published: February 2023

Abstract
While Chinese poets of the early medieval period have long been credited with the development of shanshui 山水 (landscape) poetry, the precursors of the prosody they employed merit further scrutiny. This article argues that an ancient poetics of visual augury informed early medieval shanshui lyricism and that similar iterations of nature writing emerged earlier than is often recognized. By tracing the use of the divinatory utterance yangfu 仰俯 (looking up and looking down) in earlier depictions of the natural world, the author reconsiders the visual poetics of later shanshui literature alongside texts that use analogous mantic terminology. This study concludes that, while China's first “nature poets” constructed imagery, lyrics, and personae that appear distinct if not even contradictory to one another, the poets relied on a common visual prosody derived from preestablished mantic approaches to the natural world and its representation. In so doing, this article also further highlights the underappreciated prosodic and ideological indebtedness of later shanshui poets to the authors of the Eastern Han and provides insight into the correlations that ran between diverse forms of linguistic visuality and the poetic explorations of the natural world in early China.
Space and Identity: Self-Representation of a Ming Nanjing Courtesan in Transformation
Authors: Chen Jiani 
Published: February 2023

Abstract
This article examines the poetic collections of the Ming woman writer Yang Wan 楊宛 (ca. 1600–ca. 1647), whose transformation of identity from a courtesan celebrity to a gentry wife was one of the most representative in the category of courtesan turned concubine/wife. Her marriage lasted for decades, and her role as a family woman fully developed over time. By approaching her writings from the perspective of space, it reveals how a woman perceived and interpreted her changing status by framing her self-representation and emotional expression within two feminine spaces: the pleasure quarter and the inner chamber. Yang Wan's identity transformation and her strategic exploration of the gendered spaces along with their diverse symbolic codes contribute to our knowledge of the social, textual, and cultural mobility of late imperial China.
Introducing the Tele-OCS: A validated remotely administered version of The Oxford Cognitive Screen
Authors: Webb Sam S. , Carrick Chloe , Kusec Andrea , Demeyere Nele 
Published: February 2023

Background Remote cognitive assessments are increasingly used with the rising popularity of teleneuropsychology. Here, we evaluated the performance of the remotely administered Oxford Cognitive Screen (Tele-OCS) compared to in-person administration in adult stroke survivors. Methods 40 stroke survivors (M age = 69.30, SD = 10.44; sex = 30% female) completed in-person and remote versions of the OCS on average 30 days apart, with different trained examiners. The order of administration was counterbalanced. Cohen’s d estimates were used to compare performance between modalities. Results We found that the proportion of OCS subtasks impaired did not differ across modalities (d = 0). With regards to raw subtask scores, only the picture naming subtask and executive score from the trail making subtask were found to be statistically different across modalities, though raw differences were minimal (<1 point difference on average). These statistical differences did not affect impairment classifications. Conclusions The Tele-OCS classified cognitive impairments in a comparable way to the in-person version. The validation of the Tele-OCS allows for remote assessment to increase accessibility and pragmatically aid in addressing the clinical need for stroke-specific cognitive screening in a wider population.
Effect of Sawing Variation on Hardwood Lumber Recovery—Part II: Board Count
Authors: Thomas Edward , Buehlmann Urs 
Published: February 2023

Abstract
Sawing variation (SV) describes all variations that exist in the production of lumber due to machine, material, set works, feed works, and cutting parameters. The necessary oversizing of board thickness due to SV diminishes sawmill profits and hence efforts must be made to reduce the variation. However, such efforts are costly and sawmill personnel generally do not know at which point efforts to reduce (SV) become more costly than oversizing the boards. In an accompanying paper we examined the impact of SV on lumber volume recovery and found that volume recovery increased comparatively more for thinner than for thicker kerfs and that the effect of reduced SV became more pronounced as diameter increased. In this second manuscript, the effect of SV on the quantity of boards sawn for a range of hardwood log diameters using the US Forest Service's LOg ReCovery Analysis Tool sawmill simulation software was researched and compared with the volume improvement from an earlier paper. Results showed that significant differences in the number of boards obtained was dependent on the log diameters sawn, the lumber target thickness, and the change (reduction) in SV. A minimal average recovery improvement of 3 percent due to reduced SV was observed across all kerf thicknesses, equating to a potential production value improvement of $336,000 for an 8 million board feet mill. All sawmills can benefit from reducing SV, but mills that saw large-diameter logs might consider pursuing SV reduction more aggressively than a sawmill sawing mostly small-diameter logs.
