В связи с высокой медико-социальной значимостью пограничных психических нарушений, развивающихся под влиянием различных стрессовых воздействий и патогенных факторов среды, в частности повышенным радиационным фоном, обуславливает необходимость изучения в головном мозге соответствующих нейроморфологических эквивалентов. Однако традиционные нейроморфологические и статистические методы не позволяют однозначно выявить среди множества воздействий приоритетный фактор в поражении структурных элементов головного мозга. Нейроморфологические изменения зависят не только от дозы облучения, но и от времени, прошедшего после воздействия, которое может существенно модифицировать радиационно-индуцированные эффекты. Это связано с тем, что нервная система сама с возрастом подвергается значительной структурно-функциональной перестройке. В связи с этим, необходимо использовать новые подходы, и первостепенная роль в этом должна принадлежать методам системного анализа и обработки информации, в частности математического моделирования
Due to the high medical and social significance of borderline mental disorders that develop under the influence of various stressful influences and pathogenic environmental factors, in particular, an increased radiation background, it necessitates the study of the corresponding neuromorphological equivalents in the brain. However, traditional neuromorphological and statistical methods do not make it possible to unequivocally identify the priority factor in the damage to the structural elements of the brain among the many influences. Neuromorphological changes depend not only on the radiation dose, but also on the time elapsed after exposure, which can significantly modify the radiation-induced effects. This is due to the fact that the nervous system itself undergoes significant structural and functional restructuring with age. In this regard, it is necessary to use new approaches, and the primary role in this should belong to the methods of system analysis and information processing, in particular, mathematical modeling

Indonesia has the 4th largest number of elderly population in the world. Recent studies, had shown that elderly population was associated by higher risk for developing severe infection and worse outcome compared to general population. While growing number of evidence support those finding, few local study had shown similar result. This study was aimed to describe clinical manifestation and outcome of COVID-19 in elderly population. This Observational Cohort studies was conducted on subject admitted on Gelora Joko Samudro observation hut, Gresik for COVID-19 with mild or no symptoms (based on clinical symptom classification of COVID-19 infection of Indonesian Ministry for Health, 5th Revision July 2020) and age over 60 years old. Subjects aged 20-59 were enrolled as paired control group. From total 1238 patient, there are 24 (1.94%) subjects aged more than 60. Majority of the subject were male (75%), with average age 64.7±4.78 years old. Compared to the control group, elderly had lower incidence of symptomatic infection (HR 0.4 CI95% 0.16-0.77), lower incidence of negative conversion (HR 0.1 CI95% 0.03-0.30), longer duration of viral shedding (MD 3.8 CI95% 1.73-5.77) and longer day of inpatient (MD 4.1 CI95% 2.56-5.61). In conclusion, elderly population had lower incidence of symptomatic infection but had worse clinical outcome in negative conversion, duration of viral shedding and day of hospitalization.

The supporting factors are the existence of permits to carry out business group organizational activities, having business group assistants as well as business partners, and promising business group income. While the inhibiting factors are the erratic weather around the location of kelulut honey bee cultivation, the presence of pests from kelulut honey bees, and the lack of skills from the group members in handling post-harvest honey bees. In carrying out the strategy for developing the kelulut honey bee cultivation business, the “PASIR PUTI” Business Group develops initial products by adding stup and planting flower plants that produce pollen to become additional feed for kelulut honey bees, in addition to natural food from the forest around Petak Puti Village. Furthermore, in handling post-harvest, kelulut bee honey products are marketed through business assistants as well as business partners. In pricing, the price of the product offered is sometimes uncertain. The promotion is done through the word of mouth. And the product distribution still uses travel services.

Background: Diabetes mellitus is a metabolic disease known by chronic hyperglycemia which results from defective insulin action and secretion. Various studies have documented liver disease as a major cause of mortality in patients with type 2 diabetes. It is well known that the liver plays an important role in the maintenance of normal glucose levels during fasting as well as in the postprandial period Aim: To evaluate the levels of liver markers in type 2 diabetes patients in Khartoum state. Materials and Methods: The study was conducted in Alribat University hospital, Sudan during the period from January 2018 to April 2019. Hundred subjects were included in the study, fifty patients previously diagnosed with Type 2 diabetes and similar number of age- andgender-matchedhealthy control subjects. The design of the study was cross-sectional, with a retrospective historical review through apersonal interview of all subjects.Blood was collected in a heparinized tube at room temperature and centrifuged for 10 minutes at 3500rpm, Serum liver markers concentrations were estimated by an enzymatic method in a fully Automated Biochemistry Analyzer (Cobas 3546). The data were analyzed using SPSS version 20.Results: The majority of patients were > 55 years. serum level of AST in type 2 diabetic patients and control group respectively were (31.26±10.34, 20.35±6.48) p value= 0.00), serum levels of ALT in type 2diabetic patients and control group respectively were (33.74±6.48, 19.70±6.23) p value= 0.00, serum level of ALP in Type 2 Diabetes patients and control group respectively were (125.20±49.61, 87.90±24.35) p value= 0.00,Serum level of GGT in Type 2 Diabetes patients and control group respectively were (47.72±9.01, 43.48±8.63) p value= 0.026. The mean BMI in type 2 diabetic patients and the control group respectively were (26.36±5.94,19.19±2.67), p value= 0.00, the correlation between duration of disease and liver enzymes GGT,ALT,AST and ALP respectively were (0.47,0.34,0.57,0.93). The current study showed in significant correlation between serum (GGT and ALT) and BMI of patients among type 2 diabetic patients (p value= 0.83,0.863) but significant correlation between serum (AST, ALT) and BMI of patients ( p value= 0.002,0.032).Conclusion: In the present study, a significant increase in the level of liver enzymes, ALT, AST, GGT ALP was observed in type 2 diabetic patients when compared to the normal group. Hence, we found an association between the level of liver enzymes, ALT, AST, and GGT in type 2 diabetic patients. Thus, these liver enzymes can be used as biomarkers for the assessment of type 2 diabetes, and we found no association between the level of liver enzymes, ALT, AST, and GGT in type 2 diabetic patients and duration of disease.

Published: July 2022

Abstract
An extensive exploration of the model parameter space of axisymmetric early type galaxies (ETGs) hosting a central supermassive black hole (SMBH) is conducted by means of high-resolution hydrodynamical simulations performed with our code MACER. Global properties such as (1) total SMBH accreted mass, (2) final X-ray luminosity and temperature of the X-ray emitting halos, (3) total amount of new stars formed from the cooling gas, and (4) total ejected mass in the form of supernovae and active galactic nuclei (AGN) feedback induced galactic winds, are obtained as a function of galaxy structure and internal dynamics. In addition to the galactic dark matter halo, the model galaxies are also embedded in a group/cluster dark matter halo; finally, cosmological accretion is also included, with the amount and time dependence derived from cosmological simulations. Angular momentum conservation leads to the formation of cold H i disks; these disks further evolve under the action of star formation induced by disk instabilities, of the associated mass discharge onto the central SMBH, and of the consequent AGN feedback. At the end of the simulations, the hot (metal-enriched) gas mass is roughly 10% the mass in the old stars, with twice as much having been ejected into the intergalactic medium. The cold gas disks are approximately kiloparsec in size, and the metal-rich new stars are in 0.1 kpc disks. The masses of cold gas and new stars are roughly 0.1% of the mass of the old stars. Overall, the final systems appear to reproduce quite successfully the main global properties of real ETGs.
Thermocline Depth on Water-rich Exoplanets
Authors: Lai Yanhong , Yang Jun 
Published: July 2022

Abstract
Water-rich exoplanets are a type of terrestrial planet that is water-rich and whose ocean depth can reach tens to hundreds of kilometers with no exposed continents. Due to the lack of exposed continents, neither western boundary current nor coastal upwelling exists, and ocean overturning circulation becomes the most important way to return the nutrients deposited in the deep ocean back to the thermocline and to the surface ocean. Here we investigate the depth of the thermocline in both wind-dominated and mixing-dominated systems on water-rich exoplanets using the global ocean model MITgcm. We find that the wind-driven circulation is dominated by overturning cells through Ekman pumping and subduction and by zonal (west–east) circum-longitudinal currents, similar to the Antarctic Circumpolar Current on Earth. The wind-influenced thermocline depth shows little dependence on the ocean depth, and under a large range of parameters, the thermocline is restricted within the upper layers of the ocean. The mixing-influenced thermocline is limited within the upper 10 km of the ocean and cannot reach the bottom of the ocean even under extremely strong vertical mixing. The scaling theories for the thermocline depth on Earth are applicable for the thermocline depth on water-rich exoplanets. However, due to the lack of exposed continents, the zonal and meridional flow speeds are not in the same magnitude as that in the oceans of Earth, which results in scaling relationships for water-rich exoplanets being a little different from that used on Earth.
Probing Population III Initial Mass Functions with He ii/Hα Intensity Mapping

Published: July 2022

Abstract
We demonstrate the potential of line-intensity mapping to place constraints on the initial mass function (IMF) of Population III stars via measurements of the mean He ii 1640 Å/Hα line-intensity ratio. We extend the 21cmFAST code with modern high-redshift galaxy-formation and photoionization models, and estimate the line emission from Population II and Population III galaxies at redshifts 5 ≤ z ≤ 20. In our models, mean ratio values of He ii/H α ≳ 0.1 indicate top-heavy Population III IMFs with stars of several hundred solar masses, reached at z ≳ 10 when Population III stars dominate star formation. A next-generation space mission with capabilities moderately superior to those of CDIM will be able to probe this scenario by measuring the He ii and Hα fluctuation power spectrum signals and their cross-correlation at high significance up to z ∼ 20. Moreover, regardless of the IMF, a ratio value of He ii/Hα ≲ 0.01 indicates low Population III star formation and, therefore, it signals the end of the period dominated by this stellar population. However, a detection of the corresponding He ii power spectrum may be only possible for top-heavy Population III IMFs or through cross-correlation with the stronger Hα signal. Finally, ratio values of 0.01 ≲ He ii/Hα ≲ 0.1 are complex to interpret because they can be driven by several competing effects. We discuss how various measurements at different redshifts and the combination of the line-intensity ratio with other probes can assist in constraining the Population III IMF in this case.

Abstract
We present sensitive NH3 (1,1)–(7,7) line images from the Karl G. Jansky Very Large Array toward successive shocks, which are associated with the blueshifted outflow lobe driven by the compact protobinary system L1157. Within a projection distance of 0.1 pc, our observations not only trace the quiescent and cold gas in the flattened envelope, but also illustrate the complex physical and chemical processes that take place where the high-velocity jet impinges on its surrounding medium. Specifically, the NH3 ortho-to-para ratio is enhanced by a factor of 2–2.5 along the jet path, where the velocity offset between the line peak and the blueshifted wing reaches values as high as 10 km s−1; it also shows a strong spatial correlation with the NH3 column density, which is enhanced to >1016 cm−2 toward the shock cavities. At a linear resolution of 1500 au, our refined temperature map from the seven NH3 lines shows a gradient from the warm B0 eastern cavity wall (>120 K) to the cool cavity B1 and the earlier shock B2 (<80 K), indicating shock heating.
Association between the Habitual Snack Consumption at School and the Prevalence of Overweight in Adolescent Students in Tasikmalaya, Indonesia

Published: July 2022

Background: Worldwide, More than 340 million children and adolescents have overweight problems, and snacking habits are likely contributing factors. However, little is known about habitual snack consumption in school, especially regarding snack types that may lead to overweight.
Purpose: Our study aims to analyse the association between habitual snack consumption and the prevalence of overweight in junior high school students.
Methods: An observational study with a cross-sectional design was conducted in Tasikmalaya, West Java, Indonesia, involving 397 participants from five public junior high schools. The habitual snack consumption included the consumption habits of various types of snacks (sweet-fried snacks, salty-fried snacks, sweet-non-fried snacks, salty-non-fried snacks, fruits, and sugar-sweetened beverages) measured by a food frequency questionnaire (FFQ) and categorised into rarely and often. The overweight status was determined based on the BMI-for-age z-score (BAZ) and categorised into not-overweight and overweight. We analysed the data using a logistic regression test.
Results: The habits of often consuming sweet-fried snacks (p<0.001; aOR=5.448; 95% CI=2.303–12.886), salty-fried snacks (p=0.040; aOR=3.662; 95%CI=1.063-12.621), and sugar-sweetened beverages (p=0.026; aOR= 3.100; 95%CI=1.143-8.407) were risk factors associated with overweight.
Conclusion: The habit of often consuming sweet-fried snacks was a risk factor for being overweight with the greatest odds. Therefore, education on healthy snacks could be included in school learning materials to prevent overweight in adolescent students.
Accuracy of the Preoperative Predicted Percentage of Tissue Altered Calculation in Refractive Surgery Planning for Myopic LASIK
Authors: Smadja David , Mimouni Michael , Shoshani Avi , Kaiserman Igor , Lavy Itay , Santhiago Marcony R. 
Published: July 2022

PURPOSE:
To determine the reliability of the percentage of tissue altered (PTA) calculation as part of the planning strategy for myopic laser in situ keratomileusis (LASIK) by comparing the estimated PTA provided by preoperative calculation to the postoperative PTA actually achieved in microkeratome-assisted myopic LASIK.

METHODS:
This retrospective study included 3,624 eyes of 3,624 patients who underwent mechanical microkeratome-assisted LASIK surgery for myopic correction. The calculated preoperative PTA values based on the planned flap thickness and ablation depth were compared with the actual achieved postoperative PTA using the difference of corneal central thickness postoperatively for assessing the achieved ablation depth and the intraoperative ultrasound-assisted flap thickness measurement. Regression analysis was performed to reveal preoperative parameters that might influence PTA calculation accuracy.

RESULTS:

The mean difference between the estimated and achieved PTA was 0.451 ± 3.45% (
P
< .001) (95% CI: 0.3708 to 0.5322) with a preoperative and postoperative mean PTA of 31.07 ± 4.07% and 31.52 ± 5.78%, respectively. The differences between the achieved and planned maximum ablation depth and flap thickness were 4.32 ± 13.70 µm (
P
< .001) and −1.61 ± 13.66 µm (
P
< .001), respectively.

CONCLUSIONS:
Although a statistically significant difference was found between the preoperative calculated PTA and actually achieved PTA, the difference in PTA value (less than 1%) was clinically non-significant and indicated a highly reliable metric for preoperative refractive surgery planning.
