Discovery of DCAF16 binders for targeted protein degradation
Authors: Campos Miguel , Riha Isabella , Zhang Chenlu , Mozes Chen , Scheidt Karl , Zhang Xiaoyu
Published: November 2024

Conventional small-molecule drugs primarily operate by inhibiting protein function, but this approach is limited when proteins lack well-defined ligand-binding pockets. Targeted protein degradation (TPD) offers an alternative approach by harnessing cellular degradation pathways to eliminate specific proteins. Recent studies have expanded the potential of TPD by identifying additional E3 ligases, with DCAF16 emerging as a promising candidate for facilitating protein degradation through both PROTAC and molecular glue mechanisms. In this study, we revisited a previously reported compound and discovered that it covalently binds to DCAF16. We further optimized it into a FKBP12-targeting PROTAC, MC-25B. This PROTAC engages DCAF16 at cysteines C177-179, leading to the degradation of nucleus-localized FKBP12. We further demonstrated the versatility of this DCAF16 recruiter by degrading additional endogenous proteins. Compared to the first-generation DCAF16-based PROTAC, which was derived from a fragment electrophile and targets multiple off-target cysteines, this DCAF16 recruiter-based PROTAC exhibits improved proteome-wide selectivity.
Ab initio predictions of adsorption in flexible metal-organic frameworks for water harvesting applications.
Authors: Goeminne Ruben , Van Speybroeck Veronique
Published: November 2024

Recently, metal-organic frameworks like MOF-303 and MOF-LA2-1 have demonstrated exceptional performance for water harvesting applications. To enable a reticular design of such materials, an accurate prediction of the adsorption properties with chemical accuracy and fully accounting for the flexibility is crucial. The computational prediction of water adsorption properties of metal-organic frameworks (MOFs) has become standard practice. However their predictive power to design new materials is hindered by the limited accuracy of the used interatomic potential and the limitations on how to account for the framework flexibility. In this work, we showcase a methodology to obtain chemically accurate adsorption isotherms that fully account for the framework flexibility. The method is founded on very accurate and efficiently trained machine learning potentials and transition matrix Monte Carlo simulations to account for framework flexibility. By first benchmarking the reference electronic level of theory used for the training, quantitatively accurate adsorption isotherms are obtained for MOF-303, a highly topical MOF being investigated for its potential use in water harvesting applications. We show that both an accurate level of theory and a proper inclusion of local and global framework flexibility is vital in the prediction of the adsorption properties of MOF-303. The broader applicability of our methodology is demonstrated through the study of related linker-exchanged materials, MOF-333 and MOF-LA2-1. Analyses of the density profiles of water adsorbed in these MOFs yields deeper insight into the origins and differences of the observed isotherms. An optimal water harvester should have initial seeding sites with intermediate adsorption strength, to prevent detrimental low-pressure water uptake. To increase the working capacity, linker extension strategies can be used while maintaining the initial seeding sites, as was done in the MOF-LA2-1. The proposed methodology is applicable to other guest molecules and MOFs, paving the way to future rational design of MOFs with specific adsorption properties for the application at hand.

Published: November 2024

Obturators are vital for restoring function and appearance in patients with maxillofacial defects, though traditional fabrication involves multiple clinical visits and extended production time. This technique report details a digital approach using computer-aided design/manufacturing (CAD/CAM) and 3D printing to duplicate an obturator for a 74-year-old patient with maxillary bone necrosis. By using a chairside intraoral scanner, we obtained a digital model of the existing obturator, avoiding traditional impression-taking and reducing procedural discomfort. A 3D-printed obturator was fabricated, adjusted with a tissue conditioner, and refined to ensure optimal fit. Laboratory processes included using specialized materials and retention techniques. The digital workflow minimized patient visits and improved comfort, underscoring CAD/CAM and 3D printing's potential to enhance clinical efficiency and quality of life for patients requiring complex prosthetic rehabilitation. This approach highlights the practical benefits of integrating digital and analog methods in maxillofacial prosthetics. (Int J Maxillofac Prosthetics 2024;7:16-19)

Published: November 2024

Solanum lycopersicum (tomato) provides a significant amount of vitamins, carotenes,
dietary fibres, minerals, and flavonoids, making it a valuable source of nutrients.
However, chilling injury (CI) affects tomatoes when the temperature falls below 12°C.
Postharvest losses of tomato fruit range from 25% to 42% worldwide, representing losses
both in terms of quantity and quality. This study was conducted to evaluate the
effectiveness of calcium chloride (CaCl2) treatments on tomato fruit’s CI and the
physicochemical quality of postharvest tomato fruit with CaCl2 treatment. Different
strengths of CaCl2 (0.5, 2.5, and 4.5% w/v) and control (distilled water) were prepared,
and the fruits were soaked for 10 mins as a calcium treatment. Tomato fruits were stored
at (5±1°C) prior to the physicochemical analysis; the percentage of chilling injury, surface
pitting, weight loss, pH, total soluble sugar (TSS), and concentration of vitamin C was
determined at 0, 7, 14, 28 and 42 days of storage. The data significance was analysed by
ANOVA test. The result showed that the higher concentration of CaCl2 can significantly
decrease (p<0.05) the chilling injury symptom of the tomato fruit for all treatments. The
treatment of 4.5% w/v of CaCl2 at days 28 and 42 was found to have a lower CI symptom
with (0.66±0.01%) and (1.20±0.01%) respectively. The other physicochemical
characteristics were also changed along the treatment of CaCl2.

The agricultural residues that are not well-managed will cause environmental
deterioration. In fact, they can be used as alternative sources for production and
application in various industries due to their attractive properties such as absorption
ability, mechanical properties and biodegradability. In recent advancements, agricultural
residues are broadly used to form nanocellulose. In this study, nanocellulose was extracted
from plant leaves of coconut (Cocos nucifera), sugarcane (Saccharum officinarum L.) and
lemongrass (Cymbopogon) which are abundant agricultural waste. Chemical pre-treatment
was carried out by boiling dried leaves at 80°C in NaOH. The extraction was conducted
under homogenous conditions using high pressure homogenization with speed at 1000
rpm for 30 mins to produce nanocellulose. The samples were characterized for surface
morphology, UV-Vis spectrum, Fourier transmission using FTIR and water absorption.
The properties displayed by the formed nanocellulose were analysed and compared for
further recommendation. These materials have a high potential to be used in different
fields towards a sustainable future.

Published: November 2024

Breast cancer is one of the cancers with the highest incidence and mortality rate in the
world. Curcuma caesia (Black turmeric) is known to have neuroprotective, anthelmintic,
sunscreen activity, anti-diabetic and also anti-cancer activity. This study aimed to
determine the phytochemical content and possible cytotoxic activity of C. caesia water
extract (EWCC) and C. caesia ethanol extract (EECC) on breast cancer cell lines. Samples
were extracted using two extraction methods, maceration technique using 96% ethanol as
solvent and double boiling using water as a solvent. The phytochemical content, total
phenolic content (TPC), and total flavonoid content (TFC) of each extract were
determined using spectrophotometer method. Cytotoxic activity was measured using MTT
assay on MCF-7 and 4T1 breast cancer cell lines (24 hrs and 48 hrs). Results showed that
EWCC and EECC contained flavonoids, alkaloids, and polyphenols. The values of TPC
and TFC were 106.08 mg GAE/100 g and 4.32 mg QUE/g for EECC, respectively, and
73.29 mg GAE/100 g and 3.40 mg QUE/g for EECC, respectively. Meanwhile, the
cytotoxic activity test found that EWCC did not provide cytotoxic activity on MCF-7 and
4T1 cells. In the MCF-7 cell line, EECC exhibited IC50 values of 212.90 µg/mL at 24 hrs
and 311.91 µg/mL at 48 hrs. Similarly, in the 4T1 cell line, EECC exhibited IC50 values of
161.06 µg/mL at 24 hrs and 150.89 µg/mL at 48 hrs. From these results, it can be
concluded that EECC has cytotoxic activity in MCF-7 and 4T1 breast cancer cell models,
so this extract can be studied more deeply to determine its pathway of action.

Published: November 2024

Kombucha tea is a type of tea that undergoes fermentation through the inclusion of tea
leaves, sugar, and a symbiotic culture of bacteria and yeast (SCOBY). The fermentation
process typically spans a period of around 10 to 15 days. The utilization of this substance
dates back to ancient times, mostly for medicinal purposes. The review has demonstrated
that kombucha tea has distinctive characteristics, including anticancer, antioxidant,
antimicrobial, and antifungal activities. The chemical component of kombucha plays an
important role in kombucha tea which enhances the pharmacological activities such as
acetic acid, lactic acid, phenolics and flavonoids. This paper presents an analysis of recent
findings pertaining to the potential health advantages of kombucha, along with an
examination of the chemical constituents and metabolites generated during the
fermentation process. Additionally, further recommendations are provided for future
investigations in this field.

Objective: The objective of this study is to explore the behavior of emotional polymorphism in individuals through the execution of basic tasks.
 
Theoretical Framework: It was found that individuals exhibit various components or variants of emotions within an emotional state, influenced by various external factors classified as general and task-specific. In the first case, the emotional state was composed of Contextual Emotions (EmC), and in the second by Induced Emotions (EmI). Nevertheless, each state comprised a variety of emotional components, even with different valences reported by self-reporting individuals, which was termed Emotional Polymorphism (PEm).
 
Method: A controlled experiment was designed where participants performed two basic tasks using controlled time work systems and perception. Additionally, semi-structured interviews were conducted through self-reporting, where participants were asked for statistical data as well as a description of their emotional valence.
 
Results and Discussion: The results obtained revealed that there are variations in the emotional components (CEm) that make up each emotional polymorphism, considering an initial state comprised of EmC and a final response made up of EmI.
 
Implications of the Research: Managing error through the study of the components that may amplify it can assist in improving the design of interfaces and work systems that are important in the daily lives of users, such as ATMs.
 
Originality/Value: This study contributes to the literature by exploring the behavior of the components of Emotional states, as a result of contextual factors and specific tasks.

Power, Performance, and the Limits of Contemporary Animism as a (De)colonial Perspective for Indian Caste Society
Authors: Prakash Brahma
Published: November 2024

“Contemporary animism” or what is often termed as “new animism” has emerged as one of the most powerful perspectives to understand and decolonize the indigenous cultural practices and knowledge systems in recent years. Brahmanical Hinduism (or neo-Brahmanism) is considered as a cultural-religious practice that still carries undercurrents of animism in India.2 Animist beliefs have remained strongly embedded in Brahminical religious and cultural practices, such as belief in the existence of soul, persona and so on. This article argues that the ethos of neo-Brahmanism is not only antithetical to the perspectivism of contemporary animism, it rather offers a model that can be termed as ‘inverted animism’ or the cultural practices that tend to colonize the radical potentials of animism. Such Hinduism as hegemonic cultural practices disrobe the environment from its personhood, even fetishizes the person, and turns them into objects. It is an ‘animism’ that goes against its own spirit by colonizing the personality of the object, materials and other entities.
Politicising the Public Space: On Dalit Women Sanitation Workers in India
Authors: Patil Smita M.
Published: November 2024

Caste determines the life worlds of people in India in particular and South Asia in general. Historically, it is observed that caste has conditioned the nature of public spaces. Upper castes can appropriate the public spaces legitimized by caste ideology and practice. However, colonial and post-colonial India witnessed changes in the caste system due to its (modern) legal interventions. Paradoxically, caste persists in its crude and subtle forms. It has also acquired new forms in post-independent public spaces. Caste determines certain bodily dispositions within the so-called public spaces. The ambiguous nature of modernity and the weight of tradition have drastically transformed the public space. A socially regulated economy and public institutions are determining the people, space, and mobility of the castes, too. This article investigates the nature of the stigmatized labour of Dalit women sanitation workers (who come under the manual scavenging community) within diverse public urban spaces. It analyses the various questions related to the Dalit women sanitation workers who work in select public universities, urban housing colonies, and slums in Delhi, India. It probes the Dalit women sanitation workers’ day-to-day life in caste-ridden spaces of urban- “public” spaces. One of the central questions that needs to be addressed is whether the socioeconomic space of these Dalit women workers has changed in contemporary India. Why do Dalit women have to do stigmatized work in public spaces? How are purity and pollution reinforced in elusive ways? Thus, it initiates a critique of the Indian feminist understanding of public spaces. This article acts as a way to engage with the epistemic priority of women sanitation workers to problematize Brahmanic feminism in India. Can there be any social-political engagement with the public space in the case of Dalit women sanitation workers? At the level of theory, this article critiques the dominant-Habermasian idea of the public sphere and Nancy Fraser’s counter-public to reflect on conceptual practice grounded in the Dalit women sanitation workers and public space.
Do Teachers have in-group Bias about Student Caste and Socioeconomic Status in India?
Authors: Parashari Shradha
Published: November 2024

This article studies the extent of teacher’s in-group bias in occupational expectations and grading on the basis of a student’s caste and socioeconomic status. The article adopts an experimental approach and draws on data generated from 122 teachers from 19 schools in Delhi, India. The caste and socio-economic status of students were randomly assigned to a set of essays written by them such that the assigned characteristics were not related to essay quality. The results show that high caste teachers hold higher occupational expectations from their in-group category and are biased against the low caste category. For instance, high caste teachers assign 0.53 per cent or 0.019 points higher occupational expectations to high caste students and assign 5.6 per cent or 0.19 points lower occupational expectations to low caste students. The magnitude of coefficients is small but significant at 5 per cent level (P value<0.005). In terms of marks assigned, results show, that high caste teachers assign 2.36 points or 3.22 per cent higher marks when the assigned characteristics belong to a high caste; indicating in-group bias/favor for the same caste. The coefficient is positive and significant at 5 per cent level (P- value < 0.05). In contrast, high caste teachers are shown to be biased against low caste students as they assign 2.41 points or 3.41 per cent lower marks when the assigned characteristics is a low caste. Given the ultra-competitive nature of schooling in India and the importance of grades in determining access to higher education in India, even a point disadvantage is substantial.
Populism, anti-populism and minorities: Governmental discourses on the Romani people in Greece (2015-2022)
Authors: Markou Grigoris
Published: November 2024

The beginning of the 21st century is characterized by the rise of extremism nationalism, racism and xenophobia that deeply affect minority rights, such as the Roma that face diachronically blatant discrimination and racism. Due to the fact that many of the political leaders who underestimate the rights of minorities express often a populist discourse, a debate has opened up about the relationship between populism and minorities. There are many scholars who believe that populism tends to undermine liberal features like minority protections. But is populism necessarily an anti-pluralist and anti-minority phenomenon? What about the case of left-wing populism? Why do we avoid focusing on the relationship between anti-populism and minorities? In this article, we examine the relationship between populism, anti-populism and minorities through the case of two different governmental discourses in crisis-ridden Greece. Specifically, we focus on the governmental political discourse and policies of the populist SYRIZA (2015-2019) and anti-populist ND (2019-2022) on Roma, with the aim of showing that populism is not necessarily anti-pluralist, while anti-populism is not always pluralist, as both phenomena can follow inclusionary or exclusionary logics.
The Visible ‘Caste Gaps’ amid an ‘Invisible’ Caste System in West Bengal, India: A Study of Discrimination in Bengali Society
Authors: Patra Manas
Published: November 2024

The invisibility of the caste system in Bengal is so firmly ingrained in the psyche of the upper-caste Bengali Hindu population that any acknowledgement of the same by the bhadralok class appears to be a pipe dream. This moral high ground of the bhadralok directly stands antithetical to the rampant cases of caste-based discrimination in the aforementioned state on a regular basis. However, this very inconspicuous nature of the caste system in Bengal has been hogging the centre stage of academic attention in recent years and has become a well-studied phenomenon in the process. Several scholars have catapulted fresh discussions on the visibly strong undercurrents of the caste system in Bengal and accorded a new legitimacy to the different ways in which caste caters to exclusion and discrimination on socioeconomic lines. Still, Bengal’s caste system remains relatively mild and lenient in popular perceptions compared to other states, owing to its strong pedigree as a cultural hotbed. Amid this invisibility of caste in public understanding, the economic (and occupational), religious, ideological and cultural gaps exuding from the allegedly ‘invisible’ caste system between the ‘bhadralok’ class and the marginalised communities are ironically very visible. Nevertheless, such existing caste gaps in several fields have remained relatively unexplored as there is not a great deal of scholarship acknowledging the tangible presence of these gaps. Therefore, I have, in my article, attempted to analyse these patent apertures and the lack of reciprocity in occupational, cultural and ideological transactions between the bhadralok and the so-called ‘chotolok’ as the byproducts of the deeply ossified caste hierarchy in Bengal that has gradually whittled away the human agency of the state’s severely disadvantaged marginalised groups.

The study aims to identify the possibility of rainwater harvesting in industrial zones (Eskisehir Organized Industrial Zone (EOIZ), Baksan Industrial Site, Matbaacılar Site, ESTIM Wholesalers Site, Auto Gallery, EMKO Furniture and Woodworks, Teksan Industrial Site, Auto Industrialists and Small Industry, Craft Industrial Site, New Organized Industrial Zone Development Area, and Small and Medium-sized Enterprises (SMEs)) with high water use and concentrated impermeable areas. In this case, the amount of rainwater accumulated in impermeable regions was calculated using GIS and RS to reduce the rainwater load that accumulated or reached the wastewater treatment plant. The study will directly contribute to the displaying of the green water footprint resulting from industrial impermeable zones. This work for industrial areas will be pioneering. This study was analyzed using open-source GIS software and Google Earth software, a free application that allows experts in various trade branches of rainwater harvesting in the industrial region, industrialists, and researchers who want to conduct research in this area to do so quickly and easily. When viewed from this perspective, it is clear that the work has original value in the subject and makes significant contributions to the literature. Furthermore, this work directly contributes to the Sustainable Development Goals of "Clean Water and Sanitation" and "Climate Action".

In the territory of the Republic of Kazakhstan, the national project is currently being implemented Development of a Geoid Model of the Republic of Kazakhstan as a Basis for an Integrated State System of Coordinates and Heights, according to which the relevant model of the geoid for the territory of Kazakhstan will be formed and the gravity calibration line will be established to calibrate relative gravimeters. In this regard, a relevant scientific problem aims to select the optimal high-degree global gravity field model, which should best describe the long-wave component of the geoid model for the Republic of Kazakhstan. To select the optimal model were made the comparisons of the calculated height anomalies and the components of deflection of the vertical (DOV) obtained from global geopotential models XGM2019e_2159, SGG-UGM-2, SGG-UGM-1, ЕGM2008, GECO and EIGEN-6C4 with terrestrial precision measurements. In total, 59 Laplace stations and 154 high-precision levelling stations were involved in the precision analysis. Modelling of the characteristics of the Earth’s gravity was performed with software developed at the physical geodesy laboratory of the Siberian State University of Geosystems and Technologies.
The study results suggest that the high-degree global geopotential models have an approximately common modeling error, which has a negative average value from –0.092 to –0.123 m. It may indicate a regular drift in the system of normal heights and the difference between the actual W0 and the normal U0 of potentials. In addition to the constant shift, there is a positive drift from west to east and north to south, which may indicate the accumulation of systematic errors in the geometric leveling method. The standard deviation of the component of deflection of the vertical in the plane of meridian Δ in the regions with the altitudes less than 500 m varies from 0.93 to 1.13 arcseconds, in the regions with the altitudes greater than 500 m, from 1.26 to 1.54 arcseconds, while the standard deviation of the component of the deflection of the vertical in the plane of the first vertical Δ in the regions with the altitudes less than 500 m varies from 0.70 to 0.84 arcseconds, in the regions with the altitudes greater than 500 m, from 0.62 to 0.81 arcseconds.
Based on the results given in Table 4, with the selection criteria being standard deviations, range, and mean values, the model SGG-UGM-2 was chosen the optimal high-degree global geopotential model which best describes the long-wave component of the model of the geoid for the Republic of Kazakhstan.
The Use of Unmanned Aerial Vehicles in the Documentation of Recreation Areas Within The Scope Of Cultural Heritage: The Example of The Ancient City Of Kilistra
Authors: Varol Fatih
Published: November 2024

Historical buildings have been damaged by natural events and human hands for centuries. For this reason, the importance of studies on the preservation, documentation and restoration of historical buildings is increasing all over the world. In addition, the use of technological opportunities is also becoming important in order to carry out more comprehensive studies on the sustainability of historical buildings. Studies on modeling many cultural heritage (CH) works around the world continue. In order to evaluate these models in reconstruction studies, precise data about the structure must be obtained. In parallel with technological developments, the measurement sensitivity of the devices used in this field has also increased. In addition, different technological tools that will assist in measurement activities are entering our lives day by day. Unmanned Aerial Vehicle (UAV) systems are one of them. 3D data obtained from UAVs and photogrammetric systems are sensitive data obtained quickly and at low cost. This data provides the opportunity to be used in interdisciplinary studies. This study investigates the use of UAVs in the digital documentation study of the Ancient City of Kilistra in Konya/Gökyurt. The results of the study showed that UAVs are much more practical and effective than traditional measurement techniques. It has been revealed that, if appropriate conditions are provided, UAVs can be a suitable alternative in terms of time and cost in documenting recreational CH sites. Finally, it has been determined that the high-resolution digital maps obtained not only speed up the process of documenting large areas, but also provide advantages in terms of accuracy and precision.
