Published: December 2022

<p>In this research, Thin Layer Chromatography-Densitometry has proven to be a good method for analyzing 1, 1 diphenyl 2-picrylhydrazyl (DPPH) radical scavenging activity, since this approach displayed the similar trends with UV-Vis spectrophotometric method. Three medicinal plants collected from Semarang used to evaluate both methods. The IC<sub>50</sub> value ranged from 25.26 - 4913.74 ppm shown by UV-Vis spectrophotometric and 24.74 – 4674.61 ppm using TLC-Densitometric. Meniran Dechlorophyllated (<em>Phyllanthus niruri)</em> provides the strongest antioxidant activity and the weakest de-chlorophylated parsley <em>(Petroselinum crispum</em>). The paired sample t-test points from a non-dechlorophylation extract using the TLC densitometry test significantly gives a lower IC50 value than the UV spectrophotometry method-has. The maximum increase of peak area under the UV light 365 nm up to 56.08 %. This evidence supports the presumption that the scavenging radical DPPH caused not only decreasing the maximum absorbance under UV light 516 nm but also increasing the absorbance under UV light ± 365 nm.</p>

Published: December 2022

<p>Nano-silica (NS) from rice husk ash was successfully synthesized using a sol-gel process with the addition of <em>po</em><em>lyethylene</em> glycol (PEG) 6000 and polyvinyl alcohol (PVA) as a template. The purpose of this study is to investigate the properties of NS functional groups and the effect of PEG6000 and PVA concentrations (5%, 10%, and 15% (b / v)) on the size, morphology, and distribution of nanosilica. The functional groups of NS are characterized by Fourier transform infrared (FTIR), the size and morphology of NS are characterized by scanning electron microscopy (SEM). In contrast the size analyzer characterizes the particle size distributionof particulate matter (PSA). The results indicated that the addition of PEG-6000 and PVA affected the size and morphology of NS. The FTIR spectra showed the presence of silanol (Si-OH) and siloxane (Si-O-Si) groups. According to the SEM results, the morphology of NS -PEG is round and relatively more uniform than the amorphous morphology of NS-Control and NS-PVA. Instead of PEG-6000, Sol-gel PVA can be obtained with a narrow particle size distribution.</p>

A Complete Model for Mesh Pad Mist Eliminators in Oil and Gas Processing by Analogy with Distillation Packing
Authors: Grim Charles Logan , Al-Zubail Ahmed 
Published: December 2022

Summary
Current models for pressure drop in mesh pads are not adequate for pressure drop critical applications and do not cover the flooding regime commonly encountered when mesh pads are used as a coalescer. In addition, these models do not predict the flooding capacity of mesh pads. Pressure drop and capacity models for mesh pads are presented and compared with literature experimental data for fluid systems ranging from atmospheric pressure to 85-bar natural gas. The experimental data were successfully correlated from the region of countercurrent flow through to flooding of the mesh pads. The model captures, quantitatively, the pressure drop and liquid holdup in mesh pads as well as predicting the flood point of the mesh. When combined with a separation performance method, flooding in layered mesh pads can also be predicted. The model covers both conventional and co-knit mesh pads and can be adapted to other packing geometries, requiring only dry pressure drop data.

Published: December 2022

Abstract
We recently reported that sub-acute myocarditis occurred following the initial two doses of mRNA-based vaccination against COVID-19 (0.3 mL Comirnaty®) in elderly Japanese patients with cardiac dysfunction. The present retrospective study of 76 patients shows that myocarditis following the initial doses persisted for 12 months, was associated with low levels of neutralizing antibodies, and was ameliorated by reducing the third vaccine dose. Low neutralizing antibody levels (<220 U/mL) after the initial doses were an independent predictor of persistent clinical events, defined as death or marked changes in the brain natriuretic peptide levels. When the third dose was reduced (0.1 mL), changes in the brain natriuretic peptide levels were significantly smaller (P = 0.02, n = 25), no deaths occurred due to heart failure, and neutralizing antibody levels increased 41-fold (P < 0.001) compared with the initial doses. Reduced booster doses could facilitate the worldwide distribution of mRNA vaccines.

Published: December 2022

Abstract
This research conducted to determine which minerals might be deficient or excess in Iranian Sistani cattle diet based on mostly-grazed plant species. In late spring season of Sistan basin (located in southwestern Iran), four sites including Saberi, Lorg-Bagh, Kuh-Khaje and Zahak were selected and six major forage species consumed by Sistani cows including Phragmites australis, Bolboschoenus glaucus, Aeluropus lagopoides, Tamarix spp, Cyperus longus and Setaria sp were sampled and analyzed for minerals. Average macro-mineral concentrations of calcium, phosphorus, magnesium, sodium, potassium, chorine, sulfur and micro-minerals of iron, copper, manganese, molybdenum, cobalt and selenium were 17.37, 0.78, 6.85, 15.40, 3.13, 14.22, 9.49 g/kg and 820.2, 20.0, 72.8, 93.2, 0.43, 0.21 and 0.18 mg/kg for sampling sites and 12.14, 0.77, 6.35, 17.85, 3.59, 14.40, 5.01 g/kg and 1106.0, 18.5, 64.8, 122.4, 0.32, 0.19, and 0.16 mg/kg for forage species, respectively. Comparison of the plant minerals with Sistani cattle mineral requirements showed that Sistani cattle grazing natural indigenous forages was exposed to phosphorus deficiency and iron excess.

Authors: Luo Duosheng , Zhao Yaru , Fang Zhaoyan , Zhao Yating , Han Yi , Piao Jingyu , Rong Xianglu , Guo Jiao 
Published: December 2022

Abstract
Background: Tianhuang formula (THF) is a Chinese medicine prescription that is patented and clinically approved, has been shown to improve energy metabolism, but the underlying mechanism remains poorly understood. The purpose of this study is to clarify the potential mechanisms of THF in the treatment of type 2 diabetes mellitus (T2DM).
Methods: A murine model of T2DM was induced by high-fat diet (HFD) feeding combined with low-dose streptozocin (STZ) injections, and the diabetic mice were treated with THF by gavaging for consecutive 10 weeks. Fasting blood glucose (FBG), serum insulin, blood lipid, mitochondrial Ca2+ (mCa2+) levels, mitochondrial membrane potential (MMP) as well as ATP production were analyzed. The target genes and proteins expression of visceral adipose tissue (VAT) was tested by RT-PCR and western blot, respectively. The underlying mechanism of the regulating energy metabolism effect of THF was further explored in insulin resistance model of 3T3-L1 adipocytes cultured with dexamethasone (DXM).
Results: THF restored impaired glucose tolerance and insulin resistance in diabetic mice. Serum levels of lipids were significantly decreased, as well as fasting blood glucose and insulin in THF-treated mice. THF regulated mCa2+ uptake, increased MMP and ATP content in VAT. THF increased the mRNA and protein expression of AMPK, phosphorylated AMPK (p-AMPK), MICU1, sirtuin1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α). THF could increase the mCa2+ level of 3T3-L1 adipocytes and regulate mitochondrial function. The protein expression of AMPK, p-AMPK, mCa2+ uniporter (MCU) and MICU1 decreased upon adding AMPK inhibitor compound C to 3T3-L1 adipocytes and the protein expression of MCU and MICU1 decreased upon adding the MCU inhibitor ruthenium red.
Conclusions: These results demonstrated that THF ameliorated glucose and lipid metabolism disorders in T2DM mice through improvement of AMPK/MICU1 pathway-dependent mitochondrial function in adipose tissue.

Viewing angle control for automotive display using hybrid nematic liquid crystals
Authors: Oh seungwon , Lee jaehwan , An chanheon , Lee giho 
Published: December 2022

Abstract
As many displays are installed inside electric vehicles, technologies for controlling the viewing angles are attraction. We demonstrate a viewing-angle controllable device comprising hybrid-aligned nematic (HAN) liquid crystals. In the narrow viewing mode, the optical axis distribution in the HAN cell changes from hybrid to twist by changing the viewing angle from normal to oblique. The proposed HAN cell can be switched to wide viewing mode by applying a vertical electric field. Therefore, the switchable viewing-angle-controllable device can control the driver's viewing angle and block the reflected light from the co-driver's window. The proposed mechanism can be further applied to construct an achromatic polarization rotator with angle-dependence.

Published: December 2022

Abstract

Background Adolescents and young adults are a diverse patient population with unique healthcare needs including sensitive and confidential services. Many clinics serving this population began offering telemedicine during the Covid-19 pandemic. Little is known regarding patient and parent experiences accessing these services via telemedicine. Methods To assess for trends and disparities in telemedicine utilization in the first year of the pandemic, we used the electronic health record to obtain patient demographic data from an adolescent and young adult medicine clinic in a large urban academic institution. Characteristics of patients who had accessed telemedicine were compared to those who were only seen in person. Mean age was compared using t-test, while other demographic variables were compared using chi-squared test or Fisher’s exact test. We performed qualitative semi-structured interviews with patients and parents of patients in order to characterize their experiences and preferences related to accessing adolescent medicine services via telemedicine compared to in-person care. Results Patients that identified as female, white race, Hispanic/Latinx ethnicity were more likely to have utilized telemedicine. Telemedicine use was also more prevalent among patients who were privately insured and who live farther from the clinic. Although interview participants acknowledged the convenience of telemedicine and its ability to improve access to care for people with geographic or transportation barriers, many expressed preferences for in-person visits. This was based on desire for face-to-face interactions with their providers, and perception of decreased patient and parent engagement in telemedicine visits compared to in-person visits. Participants also expressed concern that telemedicine does not afford as much confidentiality for patients. Conclusions More work is needed to address patient and parent preferences for telemedicine as an adjunct modality to in-person adolescent and young adult medicine services. Optimizing quality and access to telemedicine for this patient population can improve overall healthcare for this patient population.
