Authors: Ibrahim Saira , Andleeb Tayyaba , Ramzan Khan Muhammad , Uzair Muhammad
Published: February 2025

Inositol phosphate kinases (IPKs) play vital roles in the synthesis and regulation of cellular levels of inositol polyphosphates, which perform vital functions in eukaryotic cells as second messengers. Due to the vital biological roles of the inositol phosphates, the kinases involved in their synthesis have gained great attention. The IPK gene family has not been extensively studied in bread wheat (Triticum aestivum). In the present study, we reported a genome-wide identification, phylogenetic analysis and expression patterns of the IPK gene family in wheat. Gene structure, genome distribution, motif conservation, and gene ontology enrichment analysis were carried out systematically. A total of 24 inositol phosphate kinase (IPK) genes were identified in the wheat genome that belonged to 8 homoeologous groups. The TaIPK genes were distributed on chromosomes 1, 2, 3, 4, 5 and 7 in all the three sub-genomes A, B, and D. Based on phylogenetic analysis, these genes were classified into four subfamilies. The subfamilies were defined based on conserved domains, motifs, chromosome locations, and gene structures. Eight pairs of paralogous IPKs were identified based on the phylogenetic relationships among wheat IPKs. Gene ontology enrichment analysis revealed the significant role of IPK genes in different biological and molecular processes in addition to their role in inositol phosphate signaling. At different developmental stages, all the 24 TaIPKs exhibited diverse expression patterns in different tissues showing diversity in their biological functions. The current study identified and explored the properties of 24 IPK genes in the wheat genome at diverse levels, thus providing a strong foundation for researchers to understand the family of these kinases in wheat.

Published: February 2025

Pinus roxburghii (P. roxburghii) is an important ecological and industrial conifer of the Himalayas. Plant boom is incredibly impacted by way of environmental stresses, in particular high ranges of nitrogen (N) and ozone (O3). This work aims to explore how these factors affect the total protein content and chlorophyll levels of P. roxburghii. Three consortiums were inoculated with two-year-old P. roxburghii seedlings. The stresses of 100 kg N h−1 and 100 ppb O3 were applied for 1 month to study their effect on chlorophyll level and total protein content. To evaluate their potential mitigating effects, the fungal consortium presented promising outcomes for the chosen plant species. The elevated metabolic activities and photosynthesis rate were determined by improved total protein content and high chlorophyll level (p<zero.05). The highest observed protein content (30.57548 µg/ml) occurred under combined O3 and N stress with consortium 1 (C1+O3+N). On the other hand, consortium 2 under nitrogen stress (C2+N3) alone resulted in the lowest protein content (14.537733 µg/ml). In addition, the high photosynthesis rate was determined by enhanced chlorophyll content, and C2-treated under O3 species showed high chlorophyll content C2 had the highest Chlorophyll a levels under O3 stress. C2+O3 had the biggest impact on Chlorophyll a content, while chlorophyll b increased the most. Both C1 and C2 enhanced P. roxburghii stress resistance. Further research is needed to clarify the mechanisms underlying those interactions and perceive the particular fungal lines answerable for the found consequences.

Authors: Rizqi Febriandika Nur , Luthfiyatillah  , Marwan Mujahid bin Syed Azman Syed
Published: February 2025

Indonesia’s e-commerce market, particularly B2C, continues to expand, attracting both domestic and foreign investments. Despite this growth, a notable decline in B2C sales occurred. This drop is largely attributed to rising competition in the market, which has made it increasingly difficult for platforms to retain consumer interest. This study investigates the factors that influence Millennial Muslim consumers’ purchase intentions on B2C e-commerce in Indonesia using structural equation modeling. The respondents in this study were taken from the Millennial generation of e-commerce users. This generation was chosen because they are economically more established than Generation Z and in terms of technology use, are more expert than Baby Boomers. Initially, 700 responses were collected, but after excluding incomplete or non-qualifying data, 434 valid responses were analyzed. The findings reveal that perceived risk (β: 0.206), perceived quality (β: 0.440), and enduring involvement (β: 0.240) positively affect perceived trust, whereas situational involvement (β: -0.331) has a negative impact. Additionally, enduring involvement (β: 0.659), situational involvement (β: 0.133), and perceived trust (β: 0.103) were found to positively influence purchase intention, while perceived risk (β: -0.093) negatively affects it. The study emphasizes that enduring involvement (β: 0.659) is the strongest variable that increase purchase intention in B2C e-commerce. Enduring involvement refers to a consumer’s long-term interest and engagement with a product category, driven by personal relevance, values, or consistent motivations.

Insights into kinetic and regression models developed to estimate the abundance of antibiotic-resistant genes during biological digestion of wastewater sludge
Authors: Poorasgari Eskandar , Örmeci Banu
Published: February 2025

Wastewater treatment plants are hubs of antibiotic-resistant genes (ARGs). During wastewater treatment, ARGs accumulate in wastewater sludge and some survive biological digestion. After land application of digested sludge, ARGs are transported to soil, water, and air, and may encounter humans and animals. ARGs are typically quantified by quantitative polymerase chain reaction (qPCR) on isolated DNA. Nevertheless, DNA isolation and qPCR are time-consuming, expensive, and prone to contamination. Therefore, there is a need to estimate ARGs quantities via methods that can be readily employed. Such estimation would help to protect public health via modifying biological digestion to maximize the removal of ARGs. Two approaches that make such estimation are kinetic and regression modeling. The kinetic models have been mainly of the first order. This review examines the application of the kinetic models to estimate the abundance of ARGs during biological sludge digestion. It also discusses how biological sludge digesters can be designed using kinetic models. The literature provides single and multiple regression models, from which an ARGs -Solids -Nutrients nexus, a focal point of this review, is inferred. This review demonstrates that regression models are mathematical expressions of that nexus. Also, existing challenges are highlighted and suggestions for future are provided.

Authors: Peerzade Sabanaz , Kamat Pooja
Published: February 2025

Rapid urbanization and industrialization have significantly contributed to the pollution and degradation of water bodies through urban runoff, industrial discharge, and inadequate wastewater treatment infrastructure. This study explores the role of machine learning (ML) as a decision-support tool for addressing water quality challenges across diverse environments, including surface water, groundwater, seawater, and wastewater. We evaluated the performance of seven ML models for predicting water quality parameters using data from six years (2014–2019) of the Melbourne Eastern wastewater treatment plant, encompassing energy consumption, climate variables, and wastewater characteristics. Among the models tested, the gradient boosting model demonstrated the highest predictive accuracy, achieving a statistical measure coefficient of determination R2 score of 0.75. Key findings highlight the importance of integrating climate and water quality data to improve prediction accuracy and identify critical water parameters for enhancing future models. This review provides insights into the applicability of ML techniques in water quality management and identifies potential avenues for further research in predictive modeling.

Authors:   , Alves Larissa de Sant’ Ana
Published: February 2025

A dexmedetomidina vem sendo amplamente utilizada na medicina veterinária,
entretanto estudos que avaliem a farmacocinética e farmacodinâmica em baixas doses
administradas através de bolus intravenoso em cães, ainda é limitada. O objetivo do presente
estudo foi avaliar a farmacocinética e farmacodinâmica da dexmedetomidina (2 μg/kg) após
administração de bolus IV em seis cães adultos, hígidos (6,8 ± 3,0 kg), com velocidade de 1
μg/kg/minuto. Os parâmetros farmacocinéticos foram obtidos pela cromatografia líquida de
ultra eficiência acoplada a espectrometria de massas (UPLC-MS/MS), por coletas sanguíneas
seriadas, obtendo-se as concentrações plasmáticas do fármaco nos momentos basal e 0,05, 0,1,
0,15, 0,2, 0,25, 0,3, 0,35, 0,5, 1, 1,5, 2, 3, 4 e 5 horas após o bolus. Para farmacodinâmica, a
FC, f, PAS, PAM e PAD, a glicemia e o escore de sedação embasado pela END de Grint (0-
21), considerando-se leve (4 a 6), moderada (6 a 12) ou profunda (13 a 21), foram avaliados no
momento basal (T0), a cada 3 minutos (T3 a T21) e após 30 (T30) e 60 (T60) minutos, sendo p
≤ 0,05. Como resultados farmacocinéticos, a concentração plasmática do fármaco no tempo
zero (C0) foi de 3,13 ± 1,15 ng/mL, o tempo de meia-vida (T1/2) foi de 28,28 ± 6,14 minutos,
enquanto a área sob a curva (AUC) foi 467,44 ± 60,42 ng/mL/min, o clearance (Cl) 5,46 ± 0,91
mL/min/kg e o volume de distribuição (Vdss) foi 146,19 ± 21,04 mL/kg. A FC (bpm) reduziu
significativamente a partir de T6 (79 ± 21) até T21 (78 ± 31), comparado ao T0 (116 ± 28). A f
(mrpm) diminuiu desde T3 (43 ± 44) até T60 (41 ± 23), sendo T0 = 70 ± 48. A PAS, PAM e
PAD (mmHg) elevou-se em T18, mas ao final das avaliações (T60) não tinham mais alterações
estatisticamente relevantes. A glicemia não demonstrou alteração considerável
estatisticamente. Ocorreu sedação em todos momentos pós-bolus, com pico máximo em T12
(END 8 ± 6). A dose de 2 μg/kg da dexmedetomidina por via intravenosa, causou sedação
moderada em cães hígidos. Apesar de rápida metabolização e excreção, verificou-se alterações
cardiovasculares, porém sem repercussão clínica importante nos pacientes estudados.

Authors:   , Lima Jéssica Monique dos Santos
Published: February 2025

A pecuária representa importante atividade no Brasil, contribuindo
consideravelmente com a economia interna e externa, além de possuir papel fundamental na
constituição da renda e alimento para famílias agricultoras. Entretanto, esta atividade apresenta
grandes desafios, em especial na região nordeste, com períodos de escassez hídrica plurianuais,
fator limitante ao desenvolvimento da criação animal. Desta forma, a pesquisa teve como
objetivo avaliar o efeito da restrição hídrica nos parâmetros fisiológicos e sanguíneos em
caprinos. O experimento foi realizado no Laboratório de Medicina Interna Veterinária
(LABMIV), localizado na Universidade Federal Rural do Semi-Árido (UFERSA). Foram
utilizados 5 caprinos machos, sem raça definida, clinicamente saudáveis, pesando entre 20 e 25
kg de peso vivo (PV). Os animais foram submetidos ao modelo experimental cross-over com 3
tratamentos e 5 repetições, sendo os tratamentos experimentais divididos em três grupos, G0
(grupo controle), G9 (grupo com restrição hídrica de 9 horas) e G22 (grupo com restrição
hídrica de 22 horas). Foram avaliados os parâmetros fisiológicos, frequência respiratória e TPC
(Tempo de preenchimento capilar); coleta de sangue para realização de hemograma e análises
bioquímicas de glicose, ureia, creatinina, proteínas totais, albumina, colesterol e triglicerídeos;
e coleta de urina, esta realizada na primeira micção do animal logo após a higienização do balde
coletor, às 7 horas. As demais avaliações foram realizadas em dias distintos, o quarto e quinto
dia (D4, D5); sétimo dia (D7); décimo dia (D10) em que, ao final deste os animais iniciaram o
período de reidratação, recebendo água e comida ad libitum para que ocorresse a estabilização
hídrica, antes de iniciar o tratamento seguinte; e a última coleta realizada no décimo segundo
dia de experimento (D12). Na análise física da urina, nos grupos G9 e G22, foi possível observar
alteração na coloração, sendo essas alterações acentuadas no G22. O consumo de feno diminuiu
consideravelmente no G9. Em relação a avaliação bioquímica, a maior média encontrada para
glicose foi D7 do G22 (62,85 mg/dL); na ureia D10 do G9 (63,54 mg/dL); proteínas totais D10
do G22 (7,26 g/dL); albumina D10 do G9 (5,37g/dL); colesterol D4 do G9 (69,51 mg/dL);
triglicerídeos D5 do G9 (55,35 mg/dL); e creatinina no D7 e D10 do G22 (1,32 mg/dL). Para o
hematócrito, houve diferença (p<0,05) no D5 do G0 (27,07), G9 (36,47) e G22 (19,33). O
número de hemácias não diferiu (p>0,05) entre os grupos, exceto no D7 (5,95x106/uL) do G22.
Para o VCM houve diferença (p<0,05) no D5 e D7 dos três grupos, sendo o D7 (36,36fL) do
G22 superior aos demais dias experimentais. Ao analisar a FR e TPC, não houve diferença
(p>0,05) entre os grupos. Os resultados indicaram que apesar de terem passado por diferentes
níveis de restrição hídrica, os animais não apresentaram desequilíbrio no estado geral, pois
mantiveram o peso corporal, ressaltando que os caprinos podem sobreviver sob privação de
água até 22 horas sem efeitos nocivos.
Aplicação de protótipo de vibrações sonoras durante a maturação in vitro (MIV) de oócitos bovinos (Bos taurus): um estudo preliminar
Authors:   , Paulino Ruan da Cruz
Published: February 2025

O efeito estimulante da vibração em sistemas vivos desempenha um papel relevante na
transdução mecânica, essencial para o desenvolvimento celular. No intuito de aumentar a taxa
de sucesso da Produção In Vitro de Embriões (PIVE), o uso de vibrações de baixa frequência
durante a Maturação In Vitro (MIV) vem se mostrando promissor. Nesse contexto, objetivouse
avaliar validar um dispositivo que emite frequências sonoras e o efeito destas vibrações
durante a maturação de oócitos bovinos. Para isso, oócitos provenientes de ovários coletados
em abatedouro foram maturados e submetidos a vibrações por 5 segundos, intervalo de 60
minutos, durante 24h, nas frequências de 30 e 50 hz, enquanto o grupo controle foi mantido
sem o efeito das vibrações. Ao final da maturação, os oócitos foram expostos ao marcador
Hoechst 33342 visando avaliar a maturação nuclear e ao Mitotracker Red, visando avaliar a
maturação citoplasmática e potencial de membrana mitocondrial (PMM). Os dados foram
expressos em valores de média ± erro padrão. Após verificação da normalidade por Shapiro-
Wilk e homocedasticidade de variância por Levene, diferenças estatísticas entre os grupos
experimentais para cada variável estudada foram verificadas (p < 0,05). Nas variáveis
analisadas, não houve diferença significativa (P>0,05) entre o grupo controle e os grupos com
vibrações de 30Hz e 50Hz. Por se tratar de uma tecnologia ainda pouco estudada, o presente
estudo sinaliza perspectivas de novos ensaios com vibrações e protótipos durante a MIV e
demais etapas da PIVE em bovinos.

Orale historie heeft verschillende betekenissen. Oorspronkelijk is mondelinge geschiedenis gedefinieerd als getuigenissen en persoonlijke herinneringen van mensen die bepaalde gebeurtenissen uit de eerste hand hebben meegemaakt of die dicht genoeg bij de gebeurtenissen stonden om zich deze te herinneren. Het accent van mondelinge geschiedenis ligt op het verzamelen van gegevens over het verleden door middel van ooggetuigenverslagen van historische gebeurtenissen. De methode van mondelinge geschiedenis wordt vaak gebruikt voor het verzamelen van folkloristisch materiaal, zoals ook in het geval van Curaçao.
