Assessing the Impact of TLR4 rs4986790 Polymorphism on Bacterial Meningitis Risk: A Systematic Review and Meta-Analysis
Authors: Sekar Praveen Kumar Chandra , Veerabathiran Ramakrishnan 
Published: November 2024

Abstract

Background and Objectives:
Toll-like receptor (TLR2) gene plays an important role in the pathogenesis of bacterial meningitis (such as meningococcal meningitis and pneumococcal meningitis). The association between TLR4 rs4986790 polymorphism and the susceptibility to bacterial meningitis has been extensively studied. However, the results of these studies remain inconsistent. Therefore, we performed a meta-analysis to evaluate the association between TLR4 rs4986790 polymorphism and the susceptibility to meningococcal meningitis and pneumococcal meningitis.

Methods:
Google Scholar, Embase, and PubMed databases were searched for case–control studies on TLR4 polymorphisms and the risks of meningococcal meningitis and pneumococcal meningitis, published up to May 31, 2024. To assess the strength of the association between TLR4 polymorphism and meningococcal meningitis and pneumococcal meningitis, the odds ratios (ORs) with 95% confidence intervals (CIs) were used. The meta-analysis of the associations between the TLR4 rs4986790 polymorphism and meningococcal meningitis and pneumococcal meningitis was carried out under different genetic models. Meta-analyses were conducted using Cochrane RoB 2 tool and Metagenyo to calculate the ORs and 95% CIs. Fourteen published studies with 3599 cases and 7438 controls were included.

Results:
Overall, there was a strong correlation between TLR4 polymorphisms and meningococcal meningitis observed across three genetic models using a random-effects model: GG + GA vs. AA (OR: 0.34, 95% CI: 0.14–0.79, P = 0.01, I² = 60%); GA vs. AA (OR: 0.34, 95% CI: 0.13–0.91, P = 0.03, I² = 65%); and GG vs. AA (OR: 0.34, 95% CI: 0.14–0.78, P = 0.01, I² = 59%). Conversely, a fixed-effects model also revealed a significant association in the G vs. A model (OR: 0.84, 95% CI: 0.73–0.96, P = 0.01, I² = 38%). In pneumococcal meningitis, a fixed-effects model analysis demonstrated a significant association in the GG vs. AA model (OR: 0.35, 95% CI: 0.14–0.87, P = 0.02, I² = 48%) respectively.

Conclusion:
This meta-analysis showed a strong correlation between TLR4 rs4986790 polymorphism and susceptibility to meningococcal meningitis and pneumococcal meningitis. Further studies with diverse populations are needed to validate and strengthen these findings.
Testicular dislocation: Does timing of detection dictate management? A report of two cases
Authors: Saha Snehasish , Chatterjee Shamita , Bera Pritin 
Published: November 2024

Abstract
Testicular dislocation is a rare condition after blunt trauma to the pelvis and genitalia. It is often overlooked during initial management after trauma, and patients have been reported to present with the condition after months or years after the trauma. Diagnosis is confirmed by imaging, and management is primarily surgical. However, if patients present early with absence of other injuries requiring surgery, a manual reduction can be attempted to reposition the testis. Early management prevents testicular atrophy and spermatogenic dysfunction. Hence, a physical examination of the groin and genitalia should be mandatory in all patients with high energy trauma to the pelvis and genitalia.

Non-torsion algebraic cycles on the Jacobians of Fermat quotients
Authors: Nemoto Yusuke 
Published: November 2024

AbstractWe study the Abel-Jacobi image of the Ceresa cycle
$W_{k, e}-W_{k, e}^-$
, where
$W_{k, e}$
is the image of the k-th symmetric product of a curve X with a base point e on its Jacobian variety. For certain Fermat quotient curves of genus g, we prove that for any choice of the base point and
$k \leq g-2$
, the Abel-Jacobi image of the Ceresa cycle is non-torsion. In particular, these cycles are non-torsion modulo rational equivalence.
Hepatitis B surface antigen-negative but hepatitis B envelope antigen-positive false occult hepatitis B virus infection: A case report
Authors: Yang Shu-Sheng , Fu Fei , Xuan Qian-Kun , Zhang Zhou-Xiang , Li Zhi-Jun , Li Guang-Bo , Yu Xiao-Yu 
Published: November 2024

BACKGROUND
Occult hepatitis B infection (OBI) is characterized by the detection of hepatitis B virus (HBV) DNA in serum (usually HBV DNA < 200 IU/mL) or the liver but negativity for hepatitis B surface antigen (HBsAg). The diagnosis of OBI relies on the sensitivity of assays used in the detection of HBV DNA and HBsAg. HBsAg assays with inadequate sensitivity or inability to detect HBV S variants may lead to misdiagnosis of OBI in people with overt HBV infection.
CASE SUMMARY
We report a HBsAg-negative but hepatitis B envelope antigen-positive patient who had a significant HBV DNA level. The patient was initially diagnosed as having OBI. However, sequence analysis revealed a unique insertion of amino acid residues at positions 120-124 in the S protein, which affects the formation of a disulfide bond that is associated with the formation of a loop. It is well known that there is an overlap between the S protein and Pol protein. We found that this new insertion site occurred in polymerase/reverse transcriptase domain, indicating that this insertion might be involved in HBV pathogenicity. The patient was finally diagnosed with a false OBI.
CONCLUSION
An insertion of amino acid residues at positions 120-124 of the S protein affects the formation of immunodominant epitopes and results in negative HBsAg levels.
The Vision of Energy Security by Key Power Centers (Russia, China, USA, and the EU)
Authors: Borovsky Yu V. 
Published: November 2024

The 2020s have witnessed increasing instability in energy security. The COVID-19 pandemic, which profoundly impacted the global economy and energy industry; the fierce confrontation between Russia and the West over the war in Ukraine, which has significantly disrupted global energy supplies; the ongoing tensions of tensions in the hydrocarbon-rich Middle East; and imbalances arising from the fourth energy transition are among the key factors destabilizing the global energy supply system, resulting in high volatility in energy prices. Countries’ approaches to energy security remain largely conventional, focusing on three core aspects: security of energy supply, energy independence, and security of energy demand.This study comprehensively analyzes the current understanding of energy security by Russia, China, the USA, the EU, based on their fundamental doctrinal documents. The findings indicate that Russia, as a self-sufficient country and major energy exporter, views its energy security through the lenses of security of energy demand, security of energy supply, and energy independence. China prioritizes security of energy supply and strives for energy independence amid the energy transition, a natural approach given its critical dependence on hydrocarbon imports and status as the world’s largest source of greenhouse gases. The United States, despite becoming a net oil and gas exporter, continues to prioritize security of energy supply and energy independence, with an increasing emphasis on security of energy demand. The European Union, critically dependent on hydrocarbon imports, focuses primarily on security of energy supply and energy independence within the context of the energy transition.While Russia, China, the US, and the EU predominantly view energy security defensively, the US and the EU also adopt an offensive stance. Unlike China, the US, the EU, and Russia politicize their understanding of energy security. Despite this, Russia and China demonstrate openness to international energy cooperation, whereas the US and the EU are more inclined to promote their energy sector interests through confrontation.
Corrosion of Surface-Treated Type 304 Stainless Steel in Alkaline Subcritical Water

Published: November 2024

Surface treatment can reduce corrosion of stainless steel in hot-pressurized (subcritical/supercritical) water and, thus is being considered to control corrosion of austenitic stainless steel Type 304 (Fe-18Cr-8Ni) for application to hydrothermal liquefaction (HTL) conversion of biomass. Typical HTL conversion processes involve hot (250°C to 374°C), pressurized (4 MPa to 22 MPa) subcritical water as the conversion medium with the addition of a homogenous alkaline catalyst. The objective of this research was to determine the relative extent to which well-established surface treatments could reduce corrosion of Type 304 in simulated HTL alkaline water, with the chromia-forming Alloy 33 (Fe-33Cr-32Ni) serving as a comparative baseline. Surface treatments examined include grinding, shot peening, sandblasting, and chemical pickling. Corrosion was assessed using gravimetric measurements made after 10 d of immersion in simulated HTL alkaline water at 310°C and 10 MPa in a static autoclave test system. Analysis of the starting (preimmersion) and corroded (postimmersion) surfaces was conducted using a variety of surface characterization techniques. None of the surface treatments reduced corrosion of Type 304, relative to the mechanically-ground surface, despite achieving the desired outcomes before and during immersion. Alloy 33 is less susceptible to corrosion than Type 304 due to the formation of a more protective Cr2O3 sublayer at the oxide/metal interface.

Methods predicting the tightness of the tube-tubesheet flaring joints of heat exchangers are considered; the mechanisms of elastoplastic deformation during the creation of a mechanical roll expansion joint have been studied, and the main parameters of the mechanical flaring processes, which determine the tightness and reliability of the joints, have been established. It is shown that the performance and tightness of joints made by mechanical rolling is due to the level of contact stresses in the area plastic deformation of elements. Finite-element modeling process of expanding copper pipes into holes in tube sheets with two annular grooves has been performed, and analysis of the stress-strain state of the interaction zone of elements after the formation a contact and under the action of operational loads is given. The main unfavorable factors affecting the tightness and strength of the rolling joint are determined.

В статье получены пленки высокоэнтропийного сплава CrMnFeCoNiCu, осажденные на стальную подложку посредством вакуумного напыления в режиме магнетронного испарения. Проведено исследование локальной атомной структуры и фазового состава. Установлено, что структурное состояние сплава CrMnFeCoNiCu определяется суперпозицией вкладов эквиатомных простых кубических решеток с параметрами решеток пространственной группы P1. Обнаружен вклад в интегральную интенсивность рефлексов двух фаз, S1 и S2, которые составляют 65.7, 28.9 % соответственно. Для решеток S1, S2 методом теоретического анализа получено пространственное распределение атомов, позволившее убедиться в том, что выбранный нами сплав является твердым раствором, а также в отсутствии вторичных фаз.
The films of the high-entropy alloy CrMnFeCoNiCu were deposited on a steel substrate by magnetron vacuum deposition. We studied the local atomic structure and phase composition and established that CrMnFeCoNiCu alloy is described by the superposition of contributions from equiatomic simple cubic lattices with the P1 space group lattices. A contribution to the integral intensity of reflections from two phases, S1 and S2 provided 65.7 and 28.9 %, respectively. For the S1 and S2 lattices, using theoretical analysis, we obtained the spatial distribution of atoms, which made it possible to verify that the alloy under study represents a solid solution with the absence of secondary phases.

Проведено исследование деформируемости при прокатке алюминиевого сплава 1580, в котором скандий частично заменен малыми добавками эрбия и иттербия. Образцами служили слитки с поперечным сечением 60×200 мм, полученные литьем на установке для полунепрерывного литья. В работе было выполнено компьютерное моделирование процессов горячей и холодной прокатки слитков в программе Deform-3D, которое показало, что использование критерия Кокрофта–Латама позволяет корректно прогнозировать величину суммарного обжатия, приводящего к появлению трещин при горячей и холодной прокатке сплава 1580, легированного малыми добавками Er и Yb, что подтверждено результатами физического эксперимента. Проведенные после этого горячая прокатка слитков на стане дуо 330, а затем холодная прокатка на стане MDM ARIETE LS 400×240 подтвердили определенный виртуальным экспериментом ресурс пластичности сплава, как при горячей, так и при холодной прокатке. Установлено также, что механические свойства сплава 1580, легированного малыми добавками Er и Yb, после отжига в диапазоне температур 250–400 °С практически соответствуют свойствам сплава 1580 марочного состава, что позволяет сделать заключение о возможности снижения в нем содержания скандия путем его замены эрбием и иттербием.
A study was carried out on the deformability during rolling of aluminum alloy 1580, in which scandium was partially replaced by small additions of erbium and ytterbium. The samples were ingots with a cross section of 60×200 mm, obtained by casting in a semi-continuous casting installation. The work carried out computer modeling of the processes of hot and cold rolling of ingots in the Deform-3D program, which showed that the use of the Cockcroft–Latham criterion allows one to correctly predict the amount of total reduction leading to the appearance of cracks during hot and cold rolling of alloy 1580 alloyed with small additions of Er and Yb , which is confirmed by the results of a physical experiment. The subsequent hot rolling of the ingots on the DUO 330 mill and then cold rolling on the MDM ARIETE LS 400×240 mill confirmed the plasticity life of the alloy, determined by the virtual experiment, both during hot and cold rolling. It was also established that the mechanical properties of alloy 1580, alloyed with small additions of Er and Yb, after annealing in the temperature range 250–400°C practically correspond to the properties of alloy 1580 of the grade composition, which allows us to conclude that it is possible to reduce the scandium content in it over time. due to its replacement with Er and Yb.
Biography, Women’s Friendship, and Anglo-Catholicism: Lady Georgiana Fullerton and Her Circle
Authors: Harrison Carol E. , Wisdom Maria LaMonaca 
Published: November 2024

Abstract
The English novelist Georgiana Fullerton belonged to a cosmopolitan circle of literary friends, including especially the French writer Pauline Craven, née La Ferronnays, who published a biography of Fullerton after her death. Elizabeth Gaskell’s Life of Charlotte Brontë (1857)—a work that similarly presented itself as a tribute from one author to another as well as testimony to an intimate friendship—offers significant context for Craven’s efforts. Departing from Gaskell’s emphasis on marriage and domesticity, Craven drew on the hagiography tradition that was enjoying a mid-nineteenth-century revival. She presented her subject as a saint in the making and affirmed that Lady Georgiana’s literary talents were central to her exemplary virtue. Broader analysis of the dozens of biographical subjects that Fullerton, Craven, and their friends chose indicates a desire to reintroduce Englishwomen to an international Catholic sisterhood that they had lost with the Reformation.
