Background
Litsea glaucencens Kuth is an aromatic plant used for food seasoning food and in Mexican traditional medicine. Among, L. glaucencens leaves properties, it has proven antibacterial activity which can be used against opportunistic pathogens like Listeria monocytogenes, a foodborne bacteria that is the causal agent of listeriosis, a disease that can be fatal in susceptible individuals. The aim of this work was to investigate the antibacterial activity of L. glaucescens Kuth leaf extracts against L. monocytogenes and to identify its bioactive components.

Material and Methods
L. glaucences leaves were macerated with four solvents of different polarity (n-hexane, dichloromethane, ethyl acetate, and methanol). To determine the capacity to inhibit bacterial proliferation in vitro, agar diffusion and microdilution methods were used. Next, we determined the minimal bactericidal concentration (MBC). Finally, we determined the ratio of MBC/MIC. Metabolites present in the active methanolic extract from L. glaucescens Kuth (LgMeOH) were purified by normal-phase open column chromatography. The structure of the antibacterial metabolite was determined using nuclear magnetic resonance (1H, 13C, COSY, HSQC) and by comparison with known compounds.

Results
The LgMeOH extract was used to purify the compound responsible for the observed antimicrobial activity. This compound was identified as 5,7-dihydroxyflavanone (pinocembrin) by analysis of its spectroscopic data and comparison with those described. The MIC and MBC values obtained for pinocembrin were 0.68 mg/mL, and the ratio MBC/MIC for both LgMeOH and pinocembrin was one, which indicates bactericidal activity.

Conclusion
L. glaucences Kuth leaves and its metabolite pinocembrin can be used to treat listeriosis due the bactericidal activity against L. monocytogenes.

Published: December 2023

Background
The red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), is an important quarantine pest, which has caused serious economic losses in various palm species, such as coconut, oil palm and date palm. Finding effective biocontrol resources is important for the control of this pest and the protection of palm crops.

Methods
A pathogenic strain HJ-01 was isolated from infected and dead pupa of Tenebrio molitor using tissue separation method. The HJ-01 strain was streak cultured and purified, and its morphological, physiological, biochemical characteristics, and 16S rDNA homology were identified after conducting a pathogenicity test on RPW larvae.

Results
Strain HJ-01 exhibited remarkable pathogenicity against RPW larvae. Under the concentration of HJ-01 suspension was 1.0 × 108 cfu/mL, the mortality rate of RPW reached 82.22%, and the half-lethal time (LT50) was 4.72 days. RPW larvae infected with strain HJ-01 showed reduced movement, decreased appetite, and eventual death. As the treatment progresses, the larvae’s bodies turned red, became soft, and started to rot, resulting in the discharge of liquid. HJ-01 demonstrated the ability to produce scarlet pigment after 24 h of culture on a basic medium. Colonies of HJ-01 appeared convex, bright red, moist, and viscous, opaque in the center, irregular at the edges, and emitted an unpleasant odor. Under microscopic observation, the cells of HJ-01 appeared as short rod-shaped and flagellate, with a size ranging from (1.2–1.8) μm × (1.0–1.2) μm. Genomic DNA extraction was performed on the strain, and the 16S rDNA sequence was amplified, yielding a sequence length of 1445 bp. The sequence of strain HJ-01 displayed a 99.72% similarity to that of Serratia marcescens. Phylogenetic tree analysis further confirmed that strain HJ-01 belonged to S. marcescens. Therefore, the strain HJ-01 has a very good lethal effect on RPW larvae, and it may be used as an effective bacterium for the control of RPW.

Aims: This study aims to characterize Stomoxys spp., potential vectors of pathogens in the north-east of Gabon.
Place and Duration of Study: This research was conducted in the Minkébé forest massif, Woleu-Ntem Province, Gabon from April to May 2023 (rainy season).
Methodology: The daily captures were conducted at Mikouka, Massoko and Minkébé using Vavoua and Nzi traps. All captured specimens were morphologically identified to species using binocular microscope (Leica Microsystems ©). The identification was aided by “specific” taxonomic keys. The collected data were organized from Microsoft Office Excel 2013. This database was used to calculate numbers and proportions of specimens observed by species. Several parameters including Apparent Density per Trap per day (ADT), Shannon, Simpson, Pielou and Bray-Curtis indices were evaluated.
Results: A total of 1552 Stomoxys were caught, including 610 at Massoko, 533 at Mikouka and 409 at Minkébé. These specimens belonged to two species: Stomoxys niger niger and Stomoxys omega. Stomoxys niger niger was the most abundant with 1176 specimens caught and an ADT of 4 Stomoxys/trap/day (s/p/d). On the other hand, Stomoxys omega was poorly captured (n= 376; ADT= 1.28). As for the biotopes surveyed, Massoko (n= 619; ADT= 6.42) and Mikouka (n= 533; ADT= 5.44) were the most infested with Stomoxys spp. However, the lowest catches were recorded at Minkébé (n= 409; ADT= 4.17). The Shannon, Pielou and Simpson index values indicate relatively low levels of diversity between sites. The Shannon index reached higher values at Minkébé than at the other study sites. The Simpson and Pielou indices also had higher values at Minkébé. As for the Bray-Curtis index, its values were low between Minkébé and Mikouka (0.592), between Mikouka and Massoko (0.302) and between Minkébé and Massoko (0.384).
Conclusion: Our findings show the coexistence of Stomoxys niger niger and Stomoxys omega in Minkébé. Their presence constitutes a health risk, because these vectors could play a role in the circulation of certain pathogens in the Minkébé forest massif. So, a longitudinal study of these vectors and a screening of their infectious agents are urgently needed.

Soil is a major reservoir of terrestrial carbon and it plays an important role in the global carbon cycle. The soil organic carbon (SOC) is the fundamental factor for sustainable agriculture because of the ability in maintaining the soil fertility which is critical to soil productivity. Soil carbon pool has gained paramount importance in the recent decades owing to the alarming issues of climate change and global warming. Land use change was found to have a larger net effect on SOC storage than projected climate change. Depending on the land use management practices, soils can be a net sink or source for CO2. In this regard the present study was carried out to assess the impact of different land uses on carbon storage and mineralization in soils of selected agro-ecological units of south Kerala.The agro-ecological units (AEUs) of south Kerala namely, southern coastal plain (AEU 1), Onattukara sandy plain (AEU 3), southern laterites (AEU 8), south central laterites (AEU 9) and southern and central foothills (AEU 12) were selected. In each AEU, different agricultural land use categories as described by IPCC for the carbon inventory such as, garden land (coconut), wet land (rice), fallow (uncultivated) and plantation (rubber) were also selected for the study. The potential for carbon mineralization in soil was assessed by evaluating factors such as Total organic carbon, mineralizable carbon, particulate organic carbon, global warming potential, carbon distribution, and turnover. The total organic carbon and particulate organic carbon were higher in rubber land use and AEU 12. The mineralizable C content in soil varied from 1.40 to 3.45, 1.18 to 3.41, 1.04 to 3.04, 1.23 to 3.35 and 1.01 to 3.02 mg g⁻¹ in AEU 1, 3, 8, 9 and 12 respectively. The highest value was observed from AEU 1 and rice land use. Similar trend was obtained for global warming potential of soils based on CO2 evolution which varied from 31.82 to 78.41, 26.89 to 79.02, 22.89 to 69.02, 28.03 to 76.06 and 22.96 to 68.64 in AEU 1, 3, 8, 9 and 12 respectively. The C proportion and turnover rates were in the range of 0.25 to 0.77 and 0.04 to 0.17 respectively. The C proportion was the highest in AEU 12 and rubber land use whereas the C turnover was the highest in AEU 1 and rice land use.

Monocropping makes agriculture more susceptible to the adverse effects of climate change. Resilient agriculture systems that can buffer crops against various agricultural vulnerabilities is the need of the hour. In this context, a study was conducted to assess the impact of various rice based cropping systems on soil health.
Aims: To study the effect of different rice based cropping systems on soil enzyme activity and organic carbon.
Study Design: Randomized block design, Replications – 3.
Place and Duration of Study: Integrated Farming System Research Station (IFSRS) of Kerala Agricultural University located at Karamana, Thiruvananthapuram, during kharif, rabi and summer seasons of 2019-2020.
Methodology: The experiment consists of eleven cropping systems (T1 : rice - fallow - fallow, T2 : rice - rice - fallow, T3 : rice - daincha - cowpea, T4 : (rice + daincha) - rice - green gram, T5 : rice - cassava - amaranthus, T6 : rice - cassava - cowpea, T7 : rice - para grass - fodder cowpea, T8 : rice - fodder cowpea - fodder maize, T9 : rice - okra - culinary melon, T10 : rice - okra - yard long bean and T11 : rice - rice – amaranthus).
Results: Soil organic carbon and enzyme activities were found highest in the cropping system (rice+daincha) – rice – green gram during kharif. During rabi, soil organic carbon and activity of urease and acid phosphatase were highest in rice- daincha- cowpea while dehydrogenase activity was highest in rice- fodder cowpea – fodder maize. During summer, rice- okra – yard long bean, rice- cassava- amaranthus and rice- cassava – cowpea recorded the highest urease, acid phosphatase and dehydrogenase activity, respectively. The organic carbon was highest for the sequence rice – okra –culinary melon. The soil organic carbon and enzyme activities were least in rice- fallow-fallow cropping sequence during all the three cropping seasons.
Conclusion: Brown manuring, use of leguminous crops and cover crops in the crop sequence instead of leaving the land fallow and addition of organic sources of nutrition increase the soil organic carbon and enzymatic activity of microbes. The increase in soil organic carbon and activity of enzymes in soil owing to crop rotation of rice with arable crops relies on the crop species which are cultivated.

Authors: Srivastav Yash , Kumar Vijay , Srivastava Yashi , Kumar Madhaw 
Published: December 2023

A common condition in the world, Peptic Ulcer condition is sometimes referred to as stomach ulcers or peptic ulcers. PUD is caused by a defect in the mucosa of the stomach or duodenum that extends beyond the muscularis mucosa. PUD is the consequence of an imbalance between the aggressive and defensive elements impacting the mucosa, which occurs after gastric mucosal lesions. Peptic ulcer disease (PUD) is a widespread ailment affecting 5–10% of the world's population, with notable racial and regional variations. As a result of an imbalance between the aggressive and defensive elements impacting the mucosa, comes gastric mucosal injuries. The word "peptic" comes from the hormone pepsin, which is essential in causing mucosal breakdown. The most common cause of upper gastrointestinal bleeding in the Western world is bleeding from peptic ulcers (PUs). High rates of morbidity, mortality, and medical costs are linked to it. This review article covers the pathophysiology, aetiology, medical therapy, diagnosis, symptoms, and signs of Peptic Ulcer Disease (PUD).

Published: December 2023

AbstractLatinas holding doctoral degrees are few and far between in the academic world as compared to their White female counterparts (National Center for Educational Statistics, 2020). We explore a crucial topic of Chicana/Latina feminism, which resists traditional theoretical concepts and methodologies in the field of adult education. Chicana/Latina feminism is a feminist theory that has transcended academic disciplines since its conception in ethnic women's studies. Therefore, the purpose of this paper is to offer an in‐depth look at Chicana/Latina feminism by defining the origins of a Chicana feminist theory, exploring the need to decolonize adult educational research to allow a more inclusive space for women of color in academia, attesting to the application of a Chicana feminist epistemology with the use of testimonios, and discussing the implications of embedding Chicana feminist perspectives in adult educational research.
The black feminist: Don't exclude the voice that nurtures you
Authors: Pippins Esther S. , Pippins Essie‐Elizabeth 
Published: December 2023

AbstractIn this article, we survey quotes, narratives, and theories of Black feminist scholars to provide some historical context of the Black feminist voice that challenged notions of achievable equity and elucidated the uniqueness of challenges relative to intersecting identities such as race and gender. The article delves into three Black feminist theories in adult educational studies to explore how core tenets of these particular theories could inform the development of an adult learning model. Next, we describe our proposed adult learning model based on a restorative justice structure centered in core concepts of the evolutionary voice of Black feminism.

Synchronization of stochastic switching complex networks with a target of nonzero inputs
Authors: Tian Huanhuan , Wang Peijun 
Published: December 2023

SummaryIn this article, we study the mean square synchronization problems for complex networks with a target of nonzero inputs under stochastic switching topology that is driven by an ergodic continuous‐time Markov process. First, we design an adaptive continuous controller based on relative full states that is consist of a synchronization term and an uncertainty elimination term, where the latter term can completely eliminate the effects of target's nonzero inputs and is continuous by adding an exponential decay function with positive initial values into the denominator. By developing a stochastic Lyapunov function, we show that zero error synchronization in the mean square sense can be achieved if the union of switching graphs contains a directed spanning tree with the target being the root. Second, we design an adaptive continuous controller based on relative outputs. Finally, we give two simulation examples to validate the theoretical results.
Bio‐Inspired Artificial Retinas Based on a Fibrous Inorganic–Organic Heterostructure for Neuromorphic Vision

Published: December 2023

AbstractTo create artificial visual perception systems, artificial retina structures that can imitate the behavior of the biological retina in human vision are of great interest. However, these devices have limited abilities to emulate the structure and working principles of human retinas and the fiber‐shaped structure of optic nerves. Here, a bio‐inspired artificial retina based on a fibrous photonic artificial synapse (FPAS) formed by organic–inorganic heterojunctions on a single fiber is proposed. The two‐terminal structure of the FPAS can emulate the structure and working principle of the human retina, fiber‐shaped optic nerves, and the synaptic functions of optic neurons. The proposed FPAS is operated without external power by modulating the capture and release of photo‐generated carriers and the photo‐gating effect at the barriers formed by organic–inorganic heterojunctions. A bio‐inspired artificial retina structure can be created by aligning an FPAS on a flexible substrate to detect and memorize patterned ultraviolet light distribution for a certain period of time, after which the stored pattern image gradually decays. This artificial bio‐inspired retina device has great potential for use in wearable fiber‐structured neuromorphic visual systems.
Generative Modeling, Design, and Analysis of Spider Silk Protein Sequences for Enhanced Mechanical Properties
Authors: Lu Wei , Kaplan David L. , Buehler Markus J. 
Published: December 2023

AbstractSpider silks are remarkable materials characterized by superb mechanical properties such as strength, extensibility, and lightweightedness. Yet, to date, limited models are available to fully explore sequence‐property relationships for analysis and design. Here a custom generative large‐language model is proposed to enable the design of novel spider silk protein sequences to meet complex combinations of target mechanical properties. The model, pretrained on a large set of protein sequences, is fine‐tuned on ≈1,000 major ampullate spidroin (MaSp) sequences for which associated fiber‐level mechanical properties exist, to yield an end‐to‐end forward and inverse generative approach that is aplied in a multi‐agent strategy. Performance is assessed through: 1) a novelty analysis and protein type classification for generated spidroin sequences through Basic Local Alignment Search Tool (BLAST) searches, 2) property evaluation and comparison with similar sequences, 3) comparison of resulting molecular structures, and 4) a detailed sequence motif analyses. This work generates silk sequences with property combinations that do not exist in nature and develops a deeper understanding of the mechanistic roles of sequence patterns in achieving overarching key mechanical properties (elastic modulus (E), strength, toughness, failure strain). The model provides an efficient approach to expand the silkome dataset, facilitating further sequence‐structure analyses of silks, and establishes a foundation for synthetic silk design and optimization.
