Unravelling the fruit quality, bioactive potential and genetic insights of Indian coffee plum [Flacourtia jangomas (Lour.)Raeusch.] plants under Terai natural vegetation of West Bengal The present study aimed to unveil the morpho-biochemical characters of fruits, the presence of bioactive compounds and genetic diversity of different Indian coffee plum plants selected from the natural vegetation of the Terai region of West Bengal during the years 2022-23 and 2023-24. A wide array of variationin fruit morphology and quality aspects concerning fruit length (14.7 to 22.4 cm), fruit diameter (17.1 to 23.7 cm), fruit weight (4.37 to 7.82 g), number of seeds (5.8 to 11.1), TSS (6.2 to 10.9ºBrix), acidity (0.40 to 0.52 %), reducing sugar (4.02 to 5.80 %) and ascorbic acid content (100.5 to 156.7 mg/100g)wasnoticed. Fruits of selected plants also possessed comprehensive variation in antioxidants (63.9 to 88.7 % of DPPH inhibition), total phenols (145.7 to 278.6 µgGAE/g), flavonoids (85.1 to 163.9 mgQE/g), anthocyanin content (33.5 to 56.4 µg/100g) and carotenoid content (1.135 to 1.6114 mg/100 g). A positive correlation was noted among fruit size, quality parameters such as TSS, acidity and ascorbic acid content.Ascorbic acid content was foundto be positively correlated with fruit size, total sugar, antioxidant activity, phenol, flavonoid and carotenoids. A remarkable negative correlation was also noted between the number of fruits per cluster and the number of seeds per fruit, with other parameters. The entire population of Indian coffee plumplantsrepresented three major clusters, comprising 8, 3 and 9 different plants, based on three different parameter clusters, to create such variation. ICPG-J5 is ideal for the commercial fresh fruit market due to its large,heavier fruit and excellent biochemical properties, ascorbic acidand strong antioxidant activity. ICPG-J7 stands out for processing purposes, as it has the largest fruit size, highest weight and a balanced sweet-tangy profile. ICPG-J2 is the best choice for functional food applications, rich in flavonoids, anthocyanins and strong antioxidant properties, making it valuable for health-focused products.

Environmental Sensitivity and Digit Ratio (2D:4D): Negative Results The current study explored the associations between different levels of developmental plasticity factors—specifically, prenatal androgen exposure and the personality trait related to environmental sensitivity. We recruited participants from Japan (184 females and 90 males) and India (94 females and 86 males) and measured their personality traits of environmental sensitivity and an indirect indicator of prenatal androgen exposure, the ratio of the lengths of the index (2nd digit: 2D) and ring (4th digit: 4D) fingers (2D:4D). Overall, the analyses stratified by country and sex did not reveal a clear correlation between environmental sensitivity and 2D:4D ratios in any of the subsamples. In one subgroup, the environmental sensitivity of Japanese females showed a weak positive correlation with the left- and two-handed mean 2D:4D ratios; however, this correlation approached zero when outliers were removed and the data were reanalyzed. Finally, we considered possible explanations for the inconsistent findings regarding the associations among different levels of plasticity factors.

Improvement in The Distribution of Machinery in Drying and Finishing: A Practical Approach for The Textile Industry in Lima, Peru This research addresses the issue of non-compliance with lead times in the delivery of finished fabrics at a textile company in Lima, Peru. The study proposes an improvement in the machinery layout of the Drying and Finishing area as a practical solution. Through an in-depth analysis of the production line, it was determined that wet processing stages were poorly organized, lacking defined flow paths and causing inefficiencies. A causeeffect diagram was developed to identify key factors impacting lead time, such as programming inefficiencies, excessive work-inprocess inventory, and inadequate setup practices. These factors were evaluated using a prioritization matrix, leading to a proposal to redistribute coil and machinery space within the plant. The redesign layout incorporates principles of minimum distance, optimal flow, flexibility, and safety. The proposed changes are expected to reduce internal transport times by at least 25%, thereby improving planning, scheduling, and overall operational efficiency.

Magnetotherapy in Pain Management: Mechanisms, Clinical Applications, and Future Perspectives – A Review Magnetotherapy, the therapeutic application of magnetic fields, has gained increasing attention in recent decades for its potential role in alleviating pain through non-invasive means. By utilizing static or pulsed electromagnetic fields (PEMF), magnetotherapy influences physiological processes such as microcirculation, neural conductivity, inflammation, and tissue repair. This review examines the principles of magnetotherapy, underlying mechanisms, therapeutic applications, and clinical evidence supporting its use in pain management. It further discusses the advantages, limitations, integration with naturopathic practices, and future research prospects. Current literature indicates that magnetotherapy is a safe, adjunctive modality for managing musculoskeletal, neuropathic, and chronic pain, though standardization of treatment parameters and large-scale clinical trials remain essential.

Democratizing essential wood identification information for Central American timber markets with an ergonomically designed, interactive, bilingual smartphone app In 2022, scientists from the Center for Wood Anatomy Research at the USDA Forest Products Laboratory published a field manual entitled Identification of Central American, Mexican, and Caribbean Woods. Bilingual with English and Spanish side-by-side on each page, this publication provided step-by-step processes with simple tools to enable readers with no previous experience in wood anatomy or identification to identify woods of the region. In use, the manual presented potential ergonomic challenges in both print and PDF formats. The objective of this project was to eliminate these challenges by transforming the field manual into a smartphone app. The WhatWood? Central America app was built in Visual Studio 2022 using Microsoft’s .NET Multi-platform App UI (.NET MAUI). The app is available as a free download on both Android and iOS platforms and can run without an internet connection. Ergonomic modifications included small-screen-optimization, adjustable text, image zooming and panning, and a colorblind viewing option. Dichotomous key navigation was automated, removing the need for manual page turning. Quizzes were added to reinforce the learning of anatomical features. The settings page was configured to show only one language at a time to eliminate the potential for confusion caused by parallel translations. Transforming the original source material into a smartphone application has democratized essential wood identification information for the Central American, Caribbean, and Mexican timber markets by making it available at no cost to virtually anyone in the world with a mobile device, delivering content in both Spanish and English, eliminating potential barriers for operators with mild visual impairments, and providing interactive functionality for self-study.

Novel Aeromonas hydrophila subsp. inisa with potential phage-mediated tolerance to benzalkonium chloride Wastewater treatment plants (WWTPs) serve as hotspots for the proliferation and evolution of specialized microorganisms. Among these, Aeromonas hydrophila stands out as a bacterium capable of colonizing diverse aquatic ecosystems. Its resistance to disinfectants, such as benzalkonium chloride (BAC), is particularly concerning in wastewater treatment systems, where such traits can be propagated. Here, we present a genomic characterization of three isolates belonging to a newly identified subspecies, A. hydrophila subsp. inisa , based on comprehensive genomic analyses. These isolates exhibited higher levels of BAC resistance compared to the reference strain ATCC 7966/DSM 3017 (EC50–27 mg/L vs . 24 mg/L) and contained several prophage sequences integrated into their genomes. These prophages were associated with genetic rearrangements, which may underline phenotypic changes, such as increased antimicrobial resistance. Notably, A. hydrophila subsp. inisa 10 exhibited greater genetic rearrangements and resistance to multiple antibiotics, traits not observed in the other isolates. This study provides the first description of a phage-associated A. hydrophila subspecies isolated from a wastewater system in Central America, underscoring the role of bacteriophages in driving bacterial evolution, speciation, and adaptation to highly polluted environments, such as WWTPs.

Repurposing Alkylating Agents in Melanoma via CSA Silencing: A Novel Therapeutic Strategy Melanoma is the deadliest form of skin cancer, with resistance to alkylating agents such as Temozolomide (TMZ) and Dacarbazine (DTIC) further limiting the efficacy of these drugs, which remain palliative options when modern immunotherapies and targeted therapies fail. Here, we identify the Cockayne Syndrome group A (CSA) protein—a key component of Transcription-Coupled Nucleotide Excision Repair (TC-NER)—as a novel driver of melanoma chemo-resistance. CSA is markedly over-expressed in both primary and metastatic melanoma cells. Silencing CSA using Antisense Oligonucleotides (ASOs) robustly reduces melanoma cell proliferation, induces apoptosis, and—critically—sensitizes cells to low doses of TMZ and DTIC, while sparing normal cells. Notably, although CSA loss-of-function underlies Cockayne Syndrome (CS), a disorder characterized by defective repair of UV-induced DNA damage, these patients do not exhibit an increased incidence of skin cancer. This paradox highlights a unique biological context in which impaired CSA function promotes cellular apoptosis rather than carcinogenesis, suggesting that CSA inhibition could selectively cripple melanoma cells. These findings establish CSA as a promising therapeutic target to overcome chemo-resistance in melanoma. Combining CSA inhibition with alkylating agents offers a potential salvage strategy in patients with refractory disease and warrants further preclinical and clinical investigation.

Performance Evaluation of Periwinkle Shell Powder as Alternative to Silica Flour in High Temperature Well Cementing Operation The effect of high temperature on cement slurry is a problem in the oil and gas drilling industry. Over the years, silica flour was used to prevent the strength of cement that results from high temperature effect. But the silica flour is imported and not environmentally friendly. Hence, the need for local material that can serve as alternative becomes imperative. Periwinkle shell (Tympanostomus fuscatus) was tested in the laboratory to determine its potential use in place of the synthetic silica flour. The shell was pulverised, calcinated, and subjected to laboratory test following the requirement API RP 10B for cement testing. Cement slurry density of 15ppg at 25%BWOC, 30%BWOC and 35%BWOC concentrations of periwinkle shell powder, and temperature range of 2000C and 2500C were conducted. Rheology test, API fluid loss, compressive strength, equivalent circulating density, and annular pressure loss were examined for its suitability to be used as an additive in cement slurry. The results showed that Periwinkle shell powder gave similar results with the silica flour based on its rheological properties, equivalent circulating density (ECD), and annular pressure loss. In addition, periwinkle shell powder performed better than silica flour in all concentrations, temperatures and curing times. The results of this study showed that periwinkle shell powder is a potential alternative for silica flour as an additive for cement strength retrogression for well cementing operation.

Biochemical Assessment of Oxidative Stress in African Catfish (Clarias Heterobronchus) from Oil-Polluted Rivers in The Niger Delta, Nigeria This study ascertained the biochemical state of the African catfish, Clarias heterobronchus, from the Oloibiri and Warri rivers in Nigeria's Niger Delta, both of which have been exposed to crude oil spills for 50 years. Fish samples (n=10 each) were obtained from the two rivers and also from a fish pond in Ibadan, Oyo State, Nigeria which served as checkpoint (reference location). The physicochemical properties of the two rivers were examined as well as the concentration of heavy metals in the fish samples. The catfish's muscle, liver, gut, and gills were also examined for the activities of catalase, superoxide dismutase, glutathione S-transferase, glutathione, and malondialdehyde production. Both rivers' pH values (6.35 for Oloibiri and 6.03 for Warri river) were below the threshold that various regulatory agencies have determined is acceptable (6.5-8.5 USEPA). The control water had a high dissolved oxygen (DO) concentration (6.69±1.15 mg/l), while the Oloibiri (4.50±0.50 mg/dl) and Warri (4.01±0.25 mg/l) rivers had lower DO concentrations. The two rivers had significantly greater amounts (p&lt;0.05) of all the heavy metals evaluated than the control. Total hydrocarbon content (THC) concentrations in the control, Oloibiri, and Warri rivers were 9.52, 35.32, and 48.56 mg/l respectively. In every tissue analyzed, the MDA levels of Clarias heterobronchus were significantly (P &lt;0.05) higher in the fish from the Oloibiri and Warri rivers than in the control group. When compared to the control, lipid peroxidation in the gills of fish from the Warri River increased by 222%, while those from the Oloibiri River increased by 184%. The organs of fish from the Oloibiri and Warri rivers had significantly higher (p&lt;0.05) levels of expression of antioxidant enzymes. Overall, oxidative stress in key organs and tissues (muscle, liver, gut, and gills) indicated that Clarias heterobronchus from the Olobiri and Warrı rivers are physiologically stressed.
