AGE, AUTOIMMUNITY, AND INFLAMMATION: THE CURIOUS CASE OF IMMUNOSENESCENCE AND INFLAMM-AGING
Authors: Sundaram T. G. , Ahmed Sakir
Published: July 2022

An ever-aging population has caused an increase in the prevalence of diseases which occur in the elderly like diabetes and cancer; and autoimmune disease like rheumatoid arthritis (RA). On the other hand, ageing also causes an increased susceptibility to infections, reactivation of latent infections and a poorer vaccine response. Together, this ageing-related decline in immunity is called immunosenescence and the associated ageing-related inflammation is called inflamm-aging.

In this brief review, we describe the changes seen with ageing in innate and adaptive immunity and how these lead to the various peculiarities associated with ageing in the immune system. TEMRA cells, Senescence associated secretory phenotype (SASP) and exhausted T cells are the main changes that occur in ageing T cells. Age-associated B cells (ABCs) contribute to changes associated with autoimmunity in elderly. In the innate arm, the macrophages-led inflamm-aging cause an overall net pro-inflammatory state. However, the macrophages have reduced phagocytosis leading to accumulation of necrotic and apoptotic debris.

We also attempt to explain how immunosenescence and inflamm-aging cause defective vaccine responses and an increased predisposition to autoimmune diseases. As the average life expectancy of the world continues to increase, this is not just a curiosity to study at whim, but an indispensable part of medicine in the near-future.

POLYPHARMACY AS A THREAT TO AGING POPULATION
SoK: SCT Auditing in Certificate Transparency
Authors: Meiklejohn Sarah , DeBlasio Joe , O’Brien Devon , Thompson Chris , Yeo Kevin , Stark Emily
Published: July 2022

The Web public key infrastructure is essential to providing secure communication on the Internet today, and certificate authorities play a crucial role in this ecosystem by issuing certificates. These authorities may misissue certificates or suffer misuse attacks, however, which has given rise to the Certificate Transparency (CT) project. The goal of CT is to store all issued certificates in public logs, which can then be checked for the presence of potentially misissued certificates. Thus, the requirement that a given certificate is indeed in one (or several) of these logs lies at the core of CT. In its current deployment, however, most individual clients do not check that the certificates they see are in logs, as requesting a proof of inclusion directly reveals the certificate and thus creates the clear potential for a violation of that client’s privacy. In this paper, we explore the techniques that have been proposed for privacy-preserving auditing of certificate inclusion, focusing on their effectiveness, efficiency, and suitability in a near-term deployment. In doing so, we also explore the parallels with related problems involving browser clients. Guided by a set of constraints that we develop, we ultimately observe several key limitations in many proposals, ranging from their privacy provisions to the fact that they focus on the interaction between a client and a log but leave open the question of how a client could privately report any certificates that are missing.
Mixnet optimization methods
Authors: Ben Guirat Iness , Diaz Claudia
Published: July 2022

We propose a method to optimally select mix network parameters for a given deployment context and adversarial model. Our method considers both worstcase and average-case anonymity and selects configurations that meet worst-case constraints while maximizing average anonymity. We apply our methods to mixnet size optimization to determine the number and width of mixnet layers, and provide results for various deployment and adversarial scenarios. For cases where the deployment context suddenly changes (drop in user traffic) we evaluate countermeasures based on mix-generated dummy traffic and show that inexpensive link dummies can significantly boost protection in some of these cases.
DALock: Password Distribution-Aware Throttling
Authors: Blocki Jeremiah , Zhang Wuwei
Published: July 2022

Large-scale online password guessing attacks are widespread and pose a persistant privacy and security threat to users. The common method for mitigating the risk of online cracking is to lock out the user after a fixed number (K) of consecutive incorrect login attempts. Selecting the value of K induces a classic security-usability trade-off. When K is too large, a hacker can (quickly) break into a significant fraction of user accounts, but when K is too low, we will start to annoy honest users by locking them out after a few mistakes. Motivated by the observation that honest user mistakes typically look quite different from an online attacker’s password guesses, we introduce DALock, a distribution-aware password lockout mechanism to reduce user annoyance while minimizing user risk. As the name suggests, DALock is designed to be aware of the frequency and popularity of the password used for login attacks. At the same time, standard throttling mechanisms (e.g., K-strikes) are oblivious to the password distribution. In particular, DALock maintains an extra “hit count" in addition to “strike count" for each user, which is based on (estimates of) the cumulative probability of all login attempts for that particular account. We empirically evaluate DALock with an extensive battery of simulations using real-world password datasets. In comparison with the traditional K-strikes mechanism, our simulations indicate that DALock offers a superior simulated security/usability trade-off. For example, in one of our simulations, we are able to reduce the success rate of an attacker to 0.05% (compared to 1% for the 3strikes mechanism) whilst simultaneously reducing the unwanted lockout rate for accounts that are not under attack to just 0.08% (compared to 4% for the 3-strikes mechanism).

Published: July 2022

Prior researchers have explored the role of FDI and economic growth or financial development and economic growth in a particular sample of countries or region while no collective studies on the effect of FDI, banks and stock market on economic growth in region or income-based groups have been conducted yet. Using a balanced panel data set of the globe of 193 upper middle income (UMI), lower middle income (LMI) and high income (HMI) countries for the period of 1998 to 2018, the study ever the first time explore the role of FDI, banks and stock markets financial development on economic growth by employing static methods and Dynamic approaches which contributes to the scarce literature on the collective and across income-based groups of countries. All model findings for the global panel indicates that FDI affect economic growth significantly and positively in the global panel, lower middle income (LMI) and upper middle income (UMI) countries where it’s not true for high income (HI) countries. Banking sector development also affect economic growth significantly but negatively in the global panel, high income and upper middle-income countries while not significant for the lower middle income (LMI) countries. Stock market development also affects economic growth significantly but negatively in the global panel. Furthermore, the result concludes that FDI have a larger effect on economic growth than does banks or stock market financial development. This study suggest high income countries regards improving FDI attraction, lower middle income (LMI) countries in regards improve banking sector and collectively suggest to improve major driver and functioning of banking sector and stock markets to spur economic growth. This study is beneficial for the government channels and financial sector of the study countries to make further decision.

Physics lessons are factual lessons, and tend to be calculation activities so that a learning model is needed that allows students to be able to think critically and systematically. This writing uses a literature study by reviewing several articles in national journals. From various journal sources
Literature and Sustainable Ecosystem: An Investigation of Selected African Literary Texts
Authors: Ogundokun Sikiru Adeyemi
Published: July 2022

The fact that African literary works have gained considerable patronage in scholarly writings and debates. Most previous studies concern themselves with writers’ styles and themes whereas inadequate attention has been paid to the ecological functionality of the texts. This study, therefore, interrogates the issue of climate change and its effects on human race around the world. Adopting eco-criticism as theoretical framework, a close reading of five purposively selected African literary texts was carried out, with content analysis applied as our methodology. The study reveals that there is a break away from the old tradition of praise songs for Africa, as a continent, and a blind attack on the colonial imperialists. In the selected texts, the writers demonstrate the environmental realities of the modern society by depicting the indices of climate change and its adverse effects on man. It is observed that climate is the topmost factor which affects agriculture (crop and livestock production). Drought, flooding and desertification often cause displacement of people and other living organisms and only a safe environment can guarantee a sustainable national development. The study concludes that the world needs to come together in the fight against environmental degradation for sustainable development.

Background: Adherence to the treatment regimen is among the behaviors, which predict the successful control of the disease and decrease its intensity and negative consequences, which is influenced by several factors. The patient's beliefs and attitudes toward the disease are effective factors in disease management and adherence to treatment, and spiritual health is one of these influential variables. Objectives: The aim of this study was to determine the mediating role of spiritual health in adherence to treatment in patients with cancer. Methods: In this descriptive correlational study, the participants were 234 Iranian patients with cancer, who were selected through convenience sampling, admitted to the oncology wards of 9 selected teaching hospitals in the northern, southern, eastern, and western provinces of the country, as well as the capital in 2021. The research instruments included the Demographic and Clinical Information Questionnaire, Spiritual Well-Being Scale, and Morisky Medication Adherence Scale-8. The path analysis was done to determine the factors related to the degree of adherence to treatment, taking into account the mediating role of spiritual health. Results: The mean age of the participants in the study was 47.27 ± 15.36. The mean scores for spiritual health and adherence to treatment were 76.70 ± 13.75 and 6.47 ± 2.1, respectively. A positive and significant relationship was found between spiritual health and adherence to treatment (P-value < 0.05). The variables of marital status, the time of diagnosis, and being a religious person had a direct effect on spiritual health, and the time of diagnosis indirectly affected treatment adherence. Conclusions: According to the results, the level of spiritual health and adherence to the treatment in patients with cancer was moderate. In addition, the variable of diagnostic time affected adherence to treatment indirectly. Besides, in examining the factors affecting spiritual health, the findings indicated the effect of the variables “being religious”, “marital status”, and “the time of diagnosis”. In addition to strengthening spiritual health, it is necessary to highlight the need to follow therapeutic diets in these patients. Therefore, it is suggested to consider a program to meet the patients with cancer spiritual needs along with the physical care program.

In their new book From Breakthrough to Blockbuster: The Business of Biotechnology, Donald Drakeman, Lisa Drakeman, and Nektarios Oraiopoulos revisit a question posed by Harvard Business School Professor Gary Pisano about the ability of small, entrepreneurial biotechnology companies to compete against large pharmaceutical companies in a research-driven, capital-intensive, and highly regulated industry. While Pisano in his 2006 book Science Business: The Promise, the Reality, and the Future of Biotech found biotech had failed to live up to its promise and that large pharmaceutical companies should turn to their internal R&D because they had the resources needed to produce innovative medicines.
CLIMBING THE SPIRAL STAIRCASE HOW WOMEN CAN NAVIGATE THEIR CAREERS AND ACCELERATE SUCCESS
Authors: Book Reviewer: Nola E Masterson MS
Published: July 2022

Climbing the Spiral Staircase is focused on advice to women executives, who want to advance in their career, and desire an opportunity to join in the C Suite and on Boards of Directors. These may be women in the corporate world, or scientists that have not thought of themselves as executives yet. Certainly, a pharmaceutical or biotech company has multiple need for women in upper levels of management. Meyer gives practical advice and penetrating analysis of gender issues that are rarely acknowledged in self-help books. Her premise is that once we accept that gender makes for a different trajectory in women’s careers, we can begin to plan for it, and use the bias to succeed. Meyer comes from a heritage of South African white women and views her experience as a pioneer, chartering new territory. She sees leadership as a way of living.

Published: July 2022

[Objective] Junior nurses’ perceived risk level may affect their career satisfaction and performances. This study sought to investigate the current situation of risk perception level of junior nurses with undergraduate degrees and to determine its influencing factors, with the aim to provide a reference for nursing managers to carry out targeted training and education for junior nurses. [Methods] A total of 484 junior nurses with undergraduate degrees from five tertiary hospitals in Guangdong Province were selected by the convenience sampling method as the research participants. The general information questionnaire, risk perception questionnaire and the Chinese version of the Positive and Negative Affect Schedule (PANAS) scale were used for the survey. [Results] The enrolled junior nurses scored 85.84±13.56 (Full score was 100) on the risk perception survey. Working years, positive and negative affect, gender, and personality characteristics were the main influencing factors for junior nurses’ risk perception levels (P<0.05). [Conclusions] Junior nurses' risk perception was at a moderate and acceptable level. However, their risk perception was higher in dimensions such as physical function, occupational exposure, and time. Therefore, nursing managers should pay attention to high-risk perception items, and targeted measures should be taken according to different characteristics of nurses to improve their ability to correctly recognize risks and eliminate negative emotions in order to improve the quality of nursing services.

O objetivo deste trabalho foi prospectar publicações científicas e patentes com os representantes do gênero. A consulta foi realizada em bancos de publicações científicas e de patentes, utilizando os termos Ageratum e mentrasto. Foi possível observar um expressivo número de publicações científicas (761) em detrimento dos depósitos de patentes (294) e em ambos os documentos se destaca a área medicinal e agronômica, sendo a China a maior detentora dos depósitos (90%). Nenhuma patente concedida ou em avaliação foi encontrada no Instituto Nacional de Propriedade Industrial (INPI), apesar de terem sido compiladas 37 dissertações/teses no Brasil na área farmacológica e agronômica, campos de grande interesse comercial. Isso demonstra a falta de incentivo à propriedade intelectual na Academia do País e a necessidade das pesquisas estarem alinhadas para solucionar alguma carência da sociedade.

O presente artigo trata do monitoramento de tecnologias associadas com a aplicação do ácido ascórbico, a partir da busca de informações em bancos de patentes, utilizando a plataforma PatentInspiration®. O ácido ascórbico é um nutriente necessário a várias reações metabólicas e uma substância importante por seu caráter antioxidante, podendo ser utilizado como conservante natural de alimentos, cosméticos e fármacos. Para o levantamento das tecnologias associada ao ácido ascórbico, aplicou-se como critério de busca uma associação de palavras-chave, a saber: “ácido ascórbico”, “natural”, “conservante” e “conservante natural”. O período considerado foi de 2000 a 2018/6, resultando um total de 9.603 patentes depositadas, com o maior número de depósito recuperados no ano de 2014. A partir desse levantamento patentário, constatou-se que a principal tecnologia de aplicação do ácido ascórbico como conservante natural é uma formulação de conservantes acrescida de outros aditivos e antioxidantes naturais e que a aplicação dessas tecnologias se concentra na indústria alimentícia.

Com a crescente conscientização sobre o aquecimento global, o aumento de preço e a escassez dos combustíveis fósseis, torna-se necessário pesquisar e desenvolver fontes de energia alternativas. Uma possível fonte substituta é a biomassa, que tem grande quantidade de energia armazenada, mas perde boa parte desta para o ambiente nos processos de decomposição. O biogás é fonte de energia abundante, não poluidora, barata e que não compete com outras culturas e nem com a produção alimentícia. A partir desse contexto, o presente trabalho teve como objetivo apresentar um estudo prospectivo do estágio das pesquisas e da proteção patentária na área de biogás, syngas e catálise. Para tal, foram feitas pesquisas em bases de dados acadêmica e de patentes utilizando-se as seguintes combinações de palavras: “biogas”, “syngas” e “syngas and cataly*”. Concluiu-se que as pesquisas sobre syngas e catálise apresentam baixa maturidade e que existe bastante espaço para desenvolvimento tecnológico nessa área, incentivado, muitas vezes, por políticas públicas específicas em diversos países.

Mitochondrial DNA mutations in ageing and cancer
Authors: Smith Anna L. M. , Whitehall Julia C. , Greaves Laura C.
Published: July 2022

Advancing age is a major risk factor for malignant transformation and the development of cancer. As such, over 50% of neoplasms occur in individuals over the age of 70. The pathologies of both ageing and cancer have been characterized by respective groups of molecular hallmarks, and while some features are divergent between the two pathologies, several are shared. Perturbed mitochondrial function is one such common hallmark, and this observation therefore suggests that mitochondrial alterations may be of significance in age‐related cancer development. There is now considerable evidence documenting the accumulation of somatic mitochondrial DNA (mtDNA) mutations in ageing human postmitotic and replicative tissues. Similarly, mutations of the mitochondrial genome have been reported in human cancers for decades. The plethora of functions in which mitochondria partake, such as oxidative phosphorylation, redox balance, apoptosis and numerous biosynthetic pathways, manifests a variety of ways in which alterations in mtDNA may contribute to tumour growth. However, the specific mechanisms by which mtDNA mutations contribute to tumour progression remain elusive and often contradictory. This review aims to consolidate current knowledge and describe future direction within the field.

Solid polymer electrolytes (SPEs) represent one of the most suitable options to overcome durability and safety issues. Herein, three‐component SPEs based on poly(vinylidene fluoride‐co‐hexafluoropropylene) as a binder, the 1‐butyl‐3‐methylimidazolium thiocyanate ionic liquid as an ionic conductive component, and zeolites, to improve SPE ionic conductivity and electrochemical stability, are prepared and characterized. Different zeolite and zeolite‐like structures (clinoptilolite, ETS‐4, and ETS‐10) are used, and the effect of lithium‐ion exchange in their structures is evaluated. A clear influence of the ion exchange process on the crystallinity of the prepared samples is observed, which plays a key role in the conduction mechanisms. The ionic conductivity of the samples at room temperature is of the order of 10−3 S cm−1, making them suitable for battery applications. The assembled batteries show promising results at room temperature, proving that the ion exchange has a positive effect on battery performance. The ion‐exchanged clinoptilolite sample presents the best performance at a prolonged cycle number, with an initial discharge capacity of about 130 mAh g−1 at C/10, and a capacity retention of 70% after 50 cycles. Thus, it is proved that the ion exchange process in microporous silicates represents a suitable strategy to develop high‐performance solid‐state lithium‐ion batteries (LIBs).

Calcium phosphate (CaP) is frequently used as coating for bone implants to promote osseointegration. However, commercial CaP coatings via plasma spraying display similar microstructures, and thus fail to provide specific implants according to different surgical conditions or skeletal bone sites. Herein, inspired by the formation of natural biominerals with various morphologies mediated by amorphous precursors, CaP coatings with tunable microstructures mediated by an amorphous metastable phase are fabricated. The microstructures of the coatings are precisely controlled by both polyaspartic acid and Mg2+. The cell biological behaviors, including alkaline phosphatase activity, mineralization, and osteogenesis‐related genes expression, on the CaP coatings with different microstructures, exhibit significant differences. Furthermore, in vivo experiments demonstrate the osseointegration in different types of rats and bones indeed favors different CaP coatings. This biomimetic strategy can be used to fabricate customized bone implants that can meet the specific requirements of various surgery conditions.
