E-cadherin promotes tumorigenicity in human ovarian surface epithelium
Creators: name: Ong, Aldrich Dixon
Publisher: name: University of British Columbia
Year: 2009

description: Ovarian cancer is the most lethal gynecological cancer in the Western world, but comparatively little is known about its development. Epithelial ovarian carcinomas are thought to originate in the ovarian surface epithelium (OSE), i.e. the mesothelium covering the ovary, but experimental evidence for this origin has been lacking. Contrary to most epithelia where neoplastic progression is associated with loss of E-cadherin, this cell-cell adhesion molecule is sparse in normal human OSE but its expression increases in ovarian epithelial metaplasia and neoplasia. Concurrently, the tumors tend to acquire characteristics of the complex epithelia of the oviduct and uterus. The high proportion of ovarian cancers where such aberrant Mullerian differentiation occurs suggests that this change may confer a selective advantage on the transforming cells. Previous studies in our laboratory showed that increased E-cadherin expression may be a cause of such Mullerian differentiation. E-cadherin was transfected into SV40 large T antigen-immortalized, E-cadherin-negative cells derived from normal OSE. Constitutive expression of E-cadherin re-established normal epithelial markers that had been lost in culture, such as keratin, and induced markers of metaplasia and neoplasia, such as CA125. In the present study, SV40-immortalized, E-cadherin-transfected cells, but not the E-cadherinnegative controls, were found to be anchorage independent and formed transplantable, invasive subcutaneous and intraperitoneal adenocarcinomas in 100% of injected SOD mice. Intraperitoneally injected tumor cells seeded the mesenteries and omentum, invaded the liver and thigh musculature, and produced ascites. The presence of SV40 large T antigen in the tumor cell nuclei confirmed their origin in the transfected OSE cells. This is the first experimental model of ovarian adenocarcinomas derived by genetic manipulations of normal human OSE. The results confirm the potential of OSE to give rise to ovarian epithelial carcinomas and suggest that upregulation of E-cadherin may play a pivotal role in their progression.

description: A broad overview of the current status of proton stability in unified models of particle interactions is given which includes non - supersymmetric unification, SUSY and SUGRA unified models, unification based on extra dimensions, and string-M-theory models. The extra dimensional unification includes 5D and 6D and universal extra dimensional (UED) models, and models based on warped geometry. Proton stability in a wide array of string theory and M theory models is reviewed. These include Calabi-Yau models, grand unified models with Kac-Moody levels $k>1$, a new class of heterotic string models, models based on intersecting D branes, and string landscape models. The destabilizing effect of quantum gravity on the proton is discussed. The possibility of testing grand unified models, models based on extra dimensions and string-M-theory models via their distinctive modes is investigated. The proposed next generation proton decay experiments, HyperK, UNO, MEMPHYS, ICARUS, LANNDD (DUSEL), and LENA would shed significant light on the nature of unification complementary to the physics at the LHC. Mathematical tools for the computation of proton lifetime are given in the appendices. Prospects for the future are discussed.

description: In the urge of designing noble metal‐free and sustainable electrocatalysts for oxygen evolution reaction (OER), herein, a mineral Digenite Cu₉S₅ has been prepared from a molecular copper(I) precursor, [{(PyHS)₂CuI(PyHS)}₂](OTf)₂ (1), and utilized as an anode material in electrocatalytic OER for the first time. A hot injection of 1 yielded a pure phase and highly crystalline Cu₉S₅, which was then electrophoretically deposited (EPD) on a highly conducting nickel foam (NF) substrate. When assessed as an electrode for OER, the Cu₉S₅/NF displayed an overpotential of merely 298±3 mV at a current density of 10 mA cm⁻² in alkaline media. The overpotential recorded here supersedes the value obtained for the best reported Cu‐based as well as the benchmark precious‐metal‐based RuO₂ and IrO₂ electrocatalysts. In addition, the choronoamperometric OER indicated the superior stability of Cu₉S₅/NF, rendering its suitability as the sustainable anode material for practical feasibility. The excellent catalytic activity of Cu₉S₅ can be attributed to the formation of a crystalline CuO overlayer on the conductive Cu₉S₅ that behaves as active species to facilitate OER. This study delivers a distinct molecular precursor approach to produce highly active copper‐based catalysts that could be used as an efficient and durable OER electro(pre)catalysts relying on non‐precious metals.

description: AT2019wey is a Galactic low mass X-ray binary with a candidate black hole accretor first discovered as an optical transient by ATLAS in December 2019. It was then associated with an X-ray source discovered by SRG in March 2020. After observing a brightening in X-rays in August 2020, VLA observations of the source revealed an optically thin spectrum that subsequently shifted to optically thick, as the source continued to brighten in radio. This motivated observations of the source with the VLBA. We found a resolved source that we interpret to be a steady compact jet, a feature associated with black hole X-ray binary systems in the hard X-ray spectral state. The jet power is comparable to the accretion-disk X-ray luminosity. Here, we summarize the results from these observations.

description: For radiography applications using fast neutrons simultaneously with gammas we have developed a detector with 16 stilbene crystals in a 4$\times$4 2D array with a 5~mm pitch and a depth of 25~mm. The crystal array is read out by Silicon photomultipliers and custom signal processing electronics. The detector prototype was tested using a custom D-D fast neutron generator at the Paul Scherrer Institute. By applying a pulse shape discrimination algorithm the detector is able to detect and distinguish fast neutrons and gammas simultaneously. Various attenuating samples placed between the source and detector with different materials and thicknesses were tested and the measured macroscopic fast neutron cross sections were compared to what was expected. Deviations were studied with the help of detailed Geant4 simulations. The detection efficiency for D-D fast neutrons was measured to be around 10\%.

Professionalisation of Australian Agricultural Economics: 1920 - 1970

description: Australian agricultural economics was on the verge of professional recognition at the beginning of the 1950s. The discipline had emerged from the Second World War in a strong position due primarily to the work of the State Departments of Agriculture, the Economics Departments of the banks, and the pioneering efforts of the Bureau of Agricultural Economics. Agricultural economics as a field of study was being taken up by economics and agricultural science students alike, and research projects in agricultural economics were burgeoning. This paper investigates the factors which contributed to the professionalisation of agricultural economics in Australia after the Second World War. All vocations aspire to professional status but, even when it does receive professional recognition, a vocation is often still questioned regarding the legitimacy of that status. It is therefore significant to explore the origins and evolution of the agricultural economics profession in order to discover the reasons why it came into existence and the process by which the professionalisation occurred. The changed economic environment during and after the Second World War meant that agricultural economists were given opportunities to present a convincing case to pursue the professionalisation of their discipline. The distinguishing and overruling characteristic of a profession is the possession of specialized knowledge which has been acquired as a result of prolonged training. The knowledge is intellectual and based on the exploration of a recognized field of study. The way in which this knowledge is obtained is an important part of the professionalisation process. This paper identifies the economists and scientists who established the discipline of agricultural economics in Australian universities and set it on the path to professionalisation. The second most important aspect of professionalisation is the formation of a professional society for members and the development of a professional journal to disseminate research and other general information to members. The formation of the professional organisation associated with agricultural economics in Australia is examined in this paper. Australian agricultural economics was at the peak of its influence in the 1970s. All the mainland universities had at least one professor of agricultural economics, there was a strong professional association, annual conferences, and bi-annual outlook conferences, and three separate professional journals were in publication. The value of the agricultural economics profession was widely accepted throughout the policy community.

description: The relation between the Toda lattices and similar nonlinear chains and orthogonal polynomials on the real line has been elaborated immensely for the last decades. We examine another system of the differential-difference equations known as the Schur flow within the framework of the theory of orthogonal polynomials on the unit circle. This system can be exhibited in equivalent form as the Lax equation, and the corresponding spectral measure undergoes a simple transformation. The general result is illustrated on the modified Bessel measures on the unit circle and the long time behavior of their Verblunsky coefficients.

Dynamical Formation Scenarios for GW190521 and Prospects for Decihertz Gravitational-Wave Astronomy with GW190521-Like Binaries

description: The gravitational-wave (GW) detection of GW190521 has provided new insights on the mass distribution of black holes and new constraints for astrophysical formation channels. With independent claims of GW190521 having significant pre-merger eccentricity, we investigate what this implies for GW190521-like binaries that form dynamically. The Laser Interferometer Space Antenna (LISA) will also be sensitive to GW190521-like binaries if they are circular from an isolated formation channel. We show, however, that GW190521-like binaries that form dynamically may skip the LISA band entirely. To this end, we simulate GW190521 analogues that dynamically form via post-Newtonian binary-single scattering. From these scattering experiments, we find that GW190521-like binaries may enter the LIGO-Virgo band with significant eccentricity as suggested by recent studies, though well below an eccentricity of $e_{\rm 10Hz} \lesssim 0.7$. Eccentric GW190521-like binaries further motivate the astrophysical science case for a decihertz GW observatory, such as the kilometer-scale version of the Midband Atomic Gravitational-wave Interferometric Sensor (MAGIS). Pre-merger observations of GW190521-like binaries with such a decihertz GW detector would be able to constrain the eccentricity of GW190521-like binaries to greater precision than with just LIGO-Virgo alone. These eccentricity constraints would also provide additional insights into the possible environments that GW190521-like binaries form in.

description: Shortages of wood for burning and construction have begun to create serious environmental problems in sub-Saharan Africa. Kenya is of particular interest both because of its high population pressure and its commitment to au active reforestation movement. This paper examines the contribution that the fast-growing species, Leucaena leucocephala, can make in this effort. A simple statistical model was used to determine the soil and climatic factors that affect its growth; these results are then compared with existing conditions in Kenya. Estimated coefficients for growth and estimated output prices were used to derive a function relating the present value of net revenue to rotation length. It is demonstrated that the economically optimal rotation is just under three years. Implications for the role of L. leucocephala in addressing the projected demand for fuel and wood in Kenya are indicated.

description: This paper proposes a REversible Second-ORder Taylor (RESORT) expansion of the expenditure function to compute compensated income from ordinary demand functions as an alternative to the algorithm proposed by Vartia. These algorithms provide measures of Hicksian welfare changes and Konus-type cost of living indices. RESORT also validates the results by checking the matrix of compensated price effects. obtained through the Slutsky equation, for symmetry and negative semi-definiteness as required by expenditure minimization. In contrast, Vartia's algorithm provides no validation procedure. RESORT is similar to Vartia's algorithm in using price steps. It computes compensated income at each step "forward" from the initial to the terminal prices, and insures that the compensated income computed "backward" is equal to its value computed in the "forward" procedure. Thus, RESORT is "reversible" and guarantees unique values of compensated income for each set of prices and, as a result, also unique measures of welfare changes and cost of living indices. These unique results are not, however, guaranteed by the usual Taylor series expansion for computing compensated income.

description: A group behavior of a heterogeneous multi-agent system is studied which obeys an "average of individual vector fields" under strong couplings among the agents. Under stability of the averaged dynamics (not asking stability of individual agents), the behavior of heterogeneous multi-agent system can be estimated by the solution to the averaged dynamics. A following idea is to "design" individual agent's dynamics such that the averaged dynamics performs the desired task. A few applications are discussed including estimation of the number of agents in a network, distributed least-squares or median solver, distributed optimization, distributed state estimation, and robust synchronization of coupled oscillators. Since stability of the averaged dynamics makes the initial conditions forgotten as time goes on, these algorithms are initialization-free and suitable for plug-and-play operation. At last, nonlinear couplings are also considered, which potentially asserts that enforced synchronization gives rise to an emergent behavior of a heterogeneous multi-agent system.

description: In a recent paper, we proposed the possibility that supersymmetry breaking is communicated dominantly via a U(1)' vector multiplet. We also required that the U(1)' plays a crucial role in solving the mu problem. We discuss here in detail both the construction and the phenomenology of one class of such models. The low energy spectrum generically contains heavy sfermions, Higgsinos and exotics ~10-100 TeV; an intermediate M_Z' ~ 3-30 TeV; light gauginos ~100-1000 GeV, of which the lightest can be wino-like; a light Higgs with a mass of ~140 GeV; and a singlino which can be very light. We present a set of possible consistent charge choices. Several benchmark models are used to demonstrate characteristic phenomenological features. Special attention is devoted to interesting LHC signatures such as gluino decay and the decay patterns of the electroweak-inos. Implications for neutrino masses, exotic decays, R-parity, gauge unification, and the gravitino mass are briefly discussed.

description: A reform to the Kyoto Protocol that allows signatories to pay a fine instead of meeting the target level of abatement would achieve three goals. First, it would defuse one U.S. objection to the agreement: the concern that the cost of achieving the target might turn out to be extremely high. Second, unlike other cost-reducing measures (such as trade in pollution permits) it would increase the equilibrium number of signatories in a non-cooperative participation game. Third, it would make it easier to force signatories to comply with their obligations. We study the participation game under an escape clause using both a Nash Equilibrium and the concept of a stable set when nations are “farsighted”. We compare our results to a prominent model of International Environmental Agreements (IEAs) which finds that the equilibrium size of an IEA tends to be small when the benefits of cooperation are large. We show that with an escape clause and a properly chosen level of fine, a large IEA can be formed even when the benefits of cooperation are large.

description: Turbulence in space plasmas usually exhibits two regimes separated by a spectral break that divides the so called inertial and kinetic ranges. Large scale magnetic fluctuations are dominated by non-linear MHD wave-wave interactions following a -5/3 or -2 slope power-law spectrum. After the break, at scales in which kinetic effects take place, the magnetic spectrum follows a steeper power-law $k^{-α}$ shape given by a spectral index $α> 5/3$. Despite its ubiquitousness, the possible effects of a turbulent background spectrum in the quasilinear relaxation of solar wind temperatures are usually not considered. In this work, a quasilinear kinetic theory is used to study the evolution of the proton temperatures in an initially turbulent collisionless plasma composed by cold electrons and bi-Maxwellian protons, in which electromagnetic waves propagate along a background magnetic field. Four wave spectrum shapes are compared with different levels of wave intensity. We show that a sufficient turbulent magnetic power can drive stable protons to transverse heating, resulting in an increase in the temperature anisotropy and the reduction of the parallel proton beta. Thus, stable proton velocity distribution can evolve in such a way as to develop kinetic instabilities. This may explain why the constituents of the solar wind can be observed far from thermodynamic equilibrium and near the instability thresholds.

It is shown through specific examples how these CP-odd invariants can also be useful to determine the character of CP breaking (i.e. whether it is hard or soft CP breaking) in a given Higgs Lagrangian. We analyse in detail the cases of two and three Higgs doublets.

description: The objective of this study was to develop a dynamic programming procedure using economic analyses to assist in optimizing expenditures in the pavement resurfacing program in Kentucky. Benefit relationships were determined from expected accident reduction, improved comfort, time savings, fuel savings, and maintenance savings. The only cost input to the program was the resurfacing cost of each project.  Dynamic programming was adapted to the selection of projects for resurfacing. Over $8.4 million of additional user benefits would have been realized in 1976 if dynamic programming had been used in selecting projects. The benefit-cost ratio of sections selected for resurfacing was 3.21; dynamic programming would have yielded 4.22.

description: An emerging approach for the activation of the nitrogen molecule is the light‐driven splitting of the N–N bond. Less than ten examples for complexes capable of N₂ photoactivation are currently known, and the underlying photophysical and photochemical processes after light absorption are largely unresolved. All complexes have a central [M(µ‐η¹:η¹‐N₂)M] unit with equivalent ligand spheres around each metal. For several of these complexes, small modifications of the ligand sphere result in thermal rather than photochemical activity. Herein, we analyse the electronic structures and computed UV/Vis spectra of four complexes: two thermally and two photochemically active complexes, each either involving molybdenum or tungsten. The analysis of electronic structures and spectra is based on the molecular orbitals, difference densities and the charge‐transfer numbers provided by TheoDORE. We find that the spectra of the photochemically active complexes contain excitations with more ligand‐to‐metal charge‐transfer character and higher intensity, providing a plausible explanation for light‐induced nitrogen splitting.

description: Bose condensation is responsible for many of the most spectacular effects in physics because it can promote quantum behavior from the microscopic to the macroscopic world. Bose condensates can be distinguished by the condensing object; electron-electron Cooper-pairs are responsible for superconductivity, Helium atoms for superfluidity, and ultracold alkali atoms in vapors for coherent matter waves. Electron-hole pair (exciton) condensation has maintained special interest because it has been difficult to realize experimentally, and because exciton phase coherence is never perfectly spontaneous. Although ideal condensates can support an exciton supercurrent, it has not been clear how such a current could be induced or detected, or how its experimental manifestation would be altered by the phase-fixing exciton creation and annhilation processes which are inevitably present. In this article we explain how to induce an exciton supercurrent in separately contacted bilayer condensates, and predict electrical effects which enable unambiguous detection.

This paper looks at a panel of beach recreators from southern California and tests two possible reasons for seasonally changing preferences. We find that seasonal effects can have a substantial impact on the relative utility to the consumer of water quality and money.

description: Introduction : Ce travail explore le phénomène du suicide assisté (de bilan) chez la population âgée, lié au sentiment de vie accomplie et apporte des pistes d’accompagnement adaptées. Ce thème pousse au questionnement éthique et juridique. Le rôle du soignant, au-delà du soin, est d’offrir un accompagnement, se voulant non jugeant, individualisé et centré sur le projet de vie/mort. Questions de recherche : « Quelles sont les motivations des personnes âgées de plus de 65 ans, ne souffrant d’aucune maladie incurable menaçant leur vie et d’aucun trouble psychiatrique, à faire le choix de mourir ? » « En tant que soignant, comment les accompagner ? » Méthodologie : Ce travail est une revue de littérature. Les articles de devis quantitatifs et qualitatifs sont sélectionnés grâce à des mots clés isolés par l’outil PICO, et trouvés sur la base de données CINAHL. Ils sont traduits de l’anglais au français, analysés avec une grille quantitative/qualitative et articulés avec la théorie de l’auto-transcendance de Pamela Reed. Résultats : En Suisse, la population a accès au suicide assisté, sous réserve de certains critères. Malgré cette offre, une partie de la population reste en demande d’une assistance au suicide pour motif de vie accomplie. Ce phénomène divise et peine à être envisagé. La complexité d’évaluation du sentiment de vie accomplie, son accompagnement et l’influence du contexte socio-culturel sont les arguments principaux à cette dernière.

description: Human–robot collaboration can enhance productivity of production lines and reduce human ergonomic risk. The numbers and types of robots and stations in which robots are allocated need to be determined. Operations should be scheduled carefully when a human and robot work on a part in a station to obtain a feasible operation allocation with the highest efficiency and lowest ergonomic risk. A mixed-integer linear programming model, constraint programming model, and Benders decomposition algorithm were developed to analyse advantages of collaborative robots in assembly lines. An energy expenditure method was used to evaluate ergonomic risk. By scheduling and balancing collaborative human–robot assembly lines, operational advantages and scheduling constraints from human–robot collaboration were studied when immobile and mobile robots are used. Regression lines were developed that can help managers determine how many and what types of robots are best for a line and what the impact of robot mobility on robot and line performance can be. The best configuration for equipping a line with collaborative robots is when (number of robots)/(number of stations) is near .7 and about 37% of robots are mobile. Robots can be efficiently used in lines with both a small and large number of passive resources and in simple and mixed-model lines.

description: Pedestrian safety for school-age children has been a growing problem in recent years. Children between the ages of five and nine represent less than 10 percent of Kentucky's population but over 16 percent of all pedestrian fatalities. A study was conducted to evaluate the effectiveness of regulatory school flashers used in school zones to reduce vehicle speeds and alert motorists of pedestrian activity and to determine measures which promote safety in school zones.  Speed studies were conducted during flashing and non-flashing periods at 48 school zones where regulatory school flashers were used. The locations involved a variety of speed limits (15.6 to 24.6 m/s (35 to 55 mph)), highway types (two-lane and four-lane roads), location types (rural areas, towns, and large cities), and pedestrian and traffic volumes.  Average speed reduction during flashing periods was only 1.6 m/s (3.6 mph); 71 percent of the locations showed speed reductions less than 1.8 m/s (4 mph). Only two locations had speed reductions over 4.5 m/s (10 mph). Flashers in 24.6-m/s (55-mph) zones were found to increase the potential for inter-vehicle accidents. The presence of crossing guards or police resulted in speed reductions of approximately 4 m/s (9 mph). High pedestrian volumes in several school zones contributed to a 0.9-m/s in virtually no speed reductions. Excessively long flashing periods resulted in speed reductions of less than 1.2-m/s (2.6 mph).  Recommendations included routine inspections and improved maintenance of school flashers. Postmounted flashers should be replaced with overhead flashers in commercial areas or where sight distance is restricted. Speed enforcement was encouraged for some locations, and uniformed crossing guards were recommended where short vehicle gaps or high speeds prevail. For locations with 24.6-m/s (55-mph) to 15.6-m/s (35-mph) speed limits, the speed limits in the school zones should be increased from 11.2 m/s (25 mph) to 15.6 m/s (35 mph) during flashing periods. Special pedestrian phasing was recommended for several traffic signals near school zones.

description: We investigate properties of the interstellar medium (ISM) in galaxies hosting long-duration gamma-ray bursts (GRBs) from an analysis of atomic species (MgI, FeI) and excited fine-structure levels of ions (e.g. SiII). Our analysis is guided primarily by echelle observations of GRB 050730 and GRB 051111. These sightlines exhibit fine-structure transitions of OI, SiII, and FeII gas that have not yet been detected in intervening quasar absorption line systems. Our results indicate that the gas with large MgI equivalent width (e.g. GRB 051111) must occur at distances >~50pc from GRB afterglows to avoid photoionization. We examine the mechanisms for fine-structure excitation and find two processes can contribute: (1) indirect UV pumping by the GRB afterglow provided a far-UV intensity in excess of 10^6 times the Galactic radiation field; and (2) collisional excitation in gas with electron density n_e>10^4 cm^-3. The observed abundances of excited ions are well explained by UV pumping with the gas at approximately a few hundred pc from the afterglow for GRB 051111 and r<100pc for GRB 050730, without invoking extreme gas density and temperature in the ISM. We show that UV pumping alone provides a simple explanation for all reported detections of excited ions in GRB afterglow spectra. The presence of strong fine-structure transitions therefore may offer little constraint for the gas density or temperature. We discuss additional implications of UV pumping including its impact on chemical abundance measurements, new prospects for observing line-strength variability, and future prospects for studying the gas density and temperature. Finally, we list a series of criteria that can distinguish between the mechanisms of UV pumping and collisional excitation.

description: Considering environmental, social, and governance (ESG) factors becomes increasingly important for companies and investors. However, “ESG” is not clearly defined so far and, therefore, it is difficult to measure the ESG activity of companies. We analyze the extent and changes in 10‐K reports and proxy statements on ESG, using a textual analysis and creating an ESG dictionary. The results show an average of 4.0 % ESG words on total words in the reports. The ESG word list with 482 items can be used to quantitatively examine the extent of ESG reporting, which will be helpful especially for SRI investors. Our classification of 40 subcategories allows a highly granular analysis of different ESG related aspects. Moreover, indications for a relation between changes in reporting and real events, especially negative media presence, are detected. Regulatory bodies have to be aware of the use of such words and how they are used.

description: This paper investigates determinants of competition in agro-food trade between five transition Central European Countries (CEC-5) (Czech Republic, Hungary, Poland, Slovakia, and Slovenia) and the European Union (EU-15) countries during the preenlargement years 1995-2003. We distinguish between one-way exports and imports, and two-way successful and unsuccessful price and quality competition in agro-food trade between the CEC-5 and the EU-15. The effect of trade balance on trade competition is found more significant than the effect of export-import unit values difference. Natural and human factor endowments increase price competition and reduce unsuccessful quality competition. Higher level of economic development reduces quality competition, whereas the size of the economy reduces price competition and increases quality competition. Agricultural labor productivity improves price and quality competition. Less quality differentiated products increase price competition. Research and development (R&D) expenditures improve quality competition.

description: The purpose of the study was to determine the cost-effectiveness of widening lanes and shoulders on rural, two-lane roads. Information concerning geometries, accidents, and traffic volumes was obtained for over 15,000 miles (25,000 km) of roads. Reductions in accident rates occurred as lane and shoulder widths increased. Run-off-road and opposite direction accidents were the primary accident types associated with narrow lanes and shoulders. Reductions in accidents ranged from 10 to 39 percent for lane widening and 6 to 21 percent for shoulder widening. Priority listings were prepared for 531 projects based on critical rate factor. Priority listings were also prepared for tbe top 120 lane widening projects and the top 36 shoulder-widening projects based on benefit-cost ratios.

description: Basal Stem Rot (BSR) disease in oil palms is a significant concern in the agricultural landscape. Caused by Ganoderma sp, it poses a growing economic threat within the industry. The imperative shift is now towards preserving existing palms rather than replacing them, crucial for sustaining productivity and profitability. The challenge lies in the persistent, asymptomatic nature of the disease and the monocropping practices. Detecting BSR early is essential for effective management due to the alarming rise in its incidence. Integrated approaches, encompassing cultural practices, chemical control, and biological agents, are vital to combat this formidable pathogen and ensure the longevity of oil palm plantations.
