Pesticides play a crucial role in modern agriculture, aiding in the protection of crops from pests and diseases. However, their indiscriminate use has raised concerns about their potential adverse effects on human health and the environment. Pesticide residues in food and water supplies are a serious health hazards to the general public since long-term exposure can cause cancer, endocrine disruption, and neurotoxicity, among other health problems. In response to these concerns, researchers and health professionals have been exploring alternative approaches to mitigate the toxic effects of pesticide residues. Bioactive substances called nutraceuticals that come from whole foods including fruits, vegetables, herbs, and spices have drawn interest because of their ability to mitigate the negative effects of pesticide residues. These substances, which include minerals, vitamins, antioxidants, and polyphenols, have a variety of biological actions that may assist in the body’s detoxification and healing of harm from pesticide exposure. In this context, this review aims to explore the potential of nutraceutical interventions as a promising strategy to mitigate the toxic effects of pesticide residues.

Simple Summary Benign prostatic hyperplasia is a common condition in older intact male dogs, and it is often initially lacking in noticeable clinical signs. Due to this asymptomatic nature, it is frequently overlooked in clinical practice. Our study aimed to develop a simplified non-invasive examination plan for the early detection of subclinical benign prostatic hyperplasia in older intact dogs. We established a clinical rectal-scoring system and new diagnostic thresholds using non-invasive methods such as ultrasonography and analysis of canine prostatic-specific esterase from blood serum samples. Our study revealed elevated values of canine prostatic-specific esterase, increased prostatic volume, and higher values of prostatic artery vascular velocities in dogs with subclinical BPH. Additionally, we found a positive relationship between prostatic volume and the age and weight of the dogs. In summary, our findings indicate that multiple non-invasive examinations can aid in identifying or suspecting early stages of BPH based not only on proposed new thresholds for prostatic volume and canine prostatic-specific esterase, but also elevated prostatic artery vascular velocities, changes in size, shape, and echostructure of the prostate gland, and differences in rectal examination. This information enables practitioners’ timely intervention, preventing the progression of prostatic manifestations. Abstract Benign prostatic hyperplasia (BPH) is an androgen-related non-neoplastic enlargement of the prostate gland that commonly affects both reproductive capabilities and the general health of intact dogs. The subclinical form of BPH can be challenging to diagnose due to a lack of clinical signs, even if rectal palpation is performed. Left untreated, this condition poses risks to the dogs’ health and breeding status. This study, involving 65 male dogs, aimed to investigate subclinical BPH through rectal palpation, ultrasonography, and analysis of canine prostatic-specific esterase (CPSE). Of the participants, 35 had subclinical BPH, and 30 served as a healthy control group. Dogs suspected of subclinical BPH, as determined by examination results from ultrasonography and CPSE analysis, underwent fine needle aspiration (FNA) guided by ultrasound to enhance diagnostic precision. Findings revealed distinct differences in rectal palpation and ultrasonography between subclinical BPH and healthy dogs. This study established diagnostic thresholds based on prostatic volume and CPSE values and proposed new thresholds for subclinical BPH. Additionally, results showed that prostate gland volume depended on the weight and the age of the dog. In conclusion, early detection of this condition is possible through various examinations, such as changes in ultrasound features, CPSE levels, and rectal palpation. All together, these methods can aid practitioners in early detection of BPH and assist with scheduling screening programs for dogs, ultimately promoting their overall health and reproductive well-being. In conclusion, we advocate for routine, non-invasive prostate screenings in breeding males, underlining the effectiveness of a combination of various multiple techniques for early subclinical BPH detection.

Heavy metal ions can be introduced into the water through several point and non-point sources including leather industry, coal mining, agriculture activity and domestic waste. Regrettably, these toxic heavy metals may pose a threat to both humans and animals, particularly when they infiltrate water and soil. Heavy metal poisoning can lead to many health complications, such as liver and renal dysfunction, dermatological difficulties, and potentially even malignancies. To mitigate the risk of heavy metal ion exposure to humans and animals, it is imperative to extract them from places that have been polluted. Several conventional methods such as ion exchange, reverse osmosis, ultrafiltration, membrane filtration and chemical precipitation have been used for the removal of heavy metal ions. However, these methods have high operation costs and generate secondary pollutants during water treatment. Biosorption is an alternative approach to eliminating heavy metals from water that involves employing eco-friendly and cost-effective biomass. This review is focused on the heavy metal ions contamination in the water, biosorption methods for heavy metal removal and mathematical modeling to explain the behaviour of heavy metal adsorption. This review can be helpful to the researchers to design wastewater treatment plants for sustainable wastewater treatment.

The most prevalent type of syndromic obesity is referred to as Prader-Willi Syndrome (PWS), being determined by the lack of expression of paternal genes on chromosome 15q11.2-q13 due to genomic or epigenetic variations, such as DNA and histone methylation or acetylation. The syndrome is frequently associated with behavioral disorders, intellectual deficiencies, short stature, polyphagia, hypogonadism and muscular hypotonia, all stemming from the multiple endocrine dysfunctions characterizing this condition. Cardiovascular (CV) anomalies can manifest even in the early stages of life, and those with PWS have an elevated risk of early onset cardiovascular diseases. The somatic and behavioral aspects of the syndrome interact intricately to cause this increased risk for CV pathologies. Changes in the GH-IGF axis are seen in most Prader-Willi Syndrome (PWS) patients, irrespective of obesity. Specific cardiovascular features of GHD in adult PWS patients include reduced cardiac mass, decreased ejection fraction, and diminished chronotropic response to dobutamine.

Pathogenic Escherichia coli are the most prevalent foodborne bacteria, and their accurate detection in food samples is critical for ensuring food safety. Therefore, a quick technique named viability-qPCR (v-qPCR), which is based on the ability of a selective dye, such as propidium monoazide (PMA), to differentiate between alive and dead cells, has been developed. Despite diverse, successful applications, v-qPCR is impaired by some practical limitations, including the ability of PMA to penetrate the outer membrane of dead Gram-negative bacteria. The objective of this study is to evaluate the ability of lactic acid (LA) to improve PMA penetration and, thus, the efficiency of v-qPCR in detecting the live fraction of pathogens. The pre-treatment of E. coli ATCC 8739 cells with 10 mM LA greatly increased PMA penetration into dead cells compared to conventional PMA-qPCR assay, avoiding false positive results. The limit of detection when using LA-PMA qPCR is 1% viable cells in a mixture of dead and alive cells. The optimized LA-PMA qPCR method was reliably able to detect log 2 CFU/mL culturable E. coli in milk spiked with viable and non-viable bacteria. Lactic acid is cheap, has low toxicity, and can be used to improve the efficiency of the v-qPCR assay, which is economically interesting for larger-scale pathogen detection applications intended for food matrices.

Peri-implantitis (PI), the most widespread condition in the oral cavity, affects patients globally; thus, advanced research in both in vitro and in vivo studies is required. This study aimed to develop peri-implantitis in the rat model by oral contamination with bacteria responsible for PI in humans. The study was carried out in three stages: the extraction of the maxillary first molar to reproduce the human edentation, the mounting of the implant, and finally, the contamination of the device by gavage with Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum and Streptococcus oralis. The hematological examinations showed statistically significant increases for WBCs (white blood cells), Hb (hemoglobin), RBCs (red blood cells), MCH (mean corpuscular hemoglobin), MCHC (mean corpuscular hemoglobin concentration), and PLTs (platelets), but especially for the level of neutrophils and lymphocytes, and the systemic immunoinflammatory index completed the picture related to the inflammatory response triggered as a result of the activity of microorganisms pathogens on oral tissues. By examining the liver and kidney profile, we hypothesized that peri-implantitis is associated with systemic diseases, and the histopathological examination showed peri-implantitis lesions characterized by a marked inflammatory infiltrate with numerous neutrophils and lymphocytes. By corroborating all the results, we successfully developed a rat peri-implantitis model using a mixed bacterial infection through the oral gavage technique.

Vine-growing for the production of wine is one of the oldest and most important agricultural activities worldwide, but the winemaking process leads to vast amounts of waste. Viticulture and vinification by-products have many bioactive molecules, including polyphenols, prebiotic fibers, organic acids, and minerals. While research on the specific human health effects of grapevine residues (pomace, seeds, barks, stalks, canes, and leaves) is still ongoing, the available data suggest the potential to positively modulate the normal and dysbiotic gut microbiota (GM) using polyphenol-rich extracts obtained from winery by-products. This review provides an updated summary of the in vitro and in vivo evidence in animal models and humans concerning the ability of polyphenol-rich winery residue to be used as a GM modulator that supports their nutraceutical applications as a functional ingredient. Additionally, this review aims to enhance interest in viticulture waste (grapevine stems and leaves), as the levels of polyphenols are similar to those found in red grapes or seeds. However, more research is still needed to obtain innovative products. The valorization of winery residues is not only environmentally friendly; it can also be economically beneficial, creating added-value nutraceuticals that modulate microbiota and a new revenue stream for wine producers.

Nicotinamide mononucleotide (NMN) has emerged as a promising therapeutic intervention for age-related disorders, including type 2 diabetes. In this study, we confirmed the previously observed effects of NMN treatment on glucose uptake and investigated its underlying mechanisms in various tissues and cell lines. Through the most comprehensive proteomic analysis to date, we discovered a series of novel organ-specific effects responsible for glucose uptake as measured by the IPGTT: adipose tissue growing (suggested by increased protein synthesis and degradation and mTOR proliferation signaling upregulation). Notably, we observed the upregulation of thermogenic UCP1, promoting enhanced glucose conversion to heat in intermuscular adipose tissue while showing a surprising repressive effect on mitochondrial biogenesis in muscle and the brain. Additionally, liver and muscle cells displayed a unique response, characterized by spliceosome downregulation and concurrent upregulation of chaperones, proteasomes, and ribosomes, leading to mildly impaired and energy-inefficient protein synthesis machinery. Furthermore, our findings revealed remarkable metabolic rewiring in the brain. This involved increased production of ketone bodies, downregulation of mitochondrial OXPHOS and TCA cycle components, as well as the induction of well-known fasting-associated effects. Collectively, our data elucidate the multifaceted nature of NMN action, highlighting its organ-specific effects and their role in improving glucose uptake. These findings deepen our understanding of NMN’s therapeutic potential and pave the way for novel strategies in managing metabolic disorders.

The growth of plants is intricately influenced by interconnected biochemical and physiological activities throughout different phases, in response to environmental conditions. This study exploresthe impact of greenhouse climate on the growth, yield, and biochemistry of winter-grown cherry tomatoes (Cheramy F1). Climatic conditions ranged from a minimum of 10.5°C to the highest of 41.3°C (average 21.22°C) temperature during the vegetative stage and from 8.2°C to 32.3°C (average 20.89 °C) during the fruit-bearing stage, with an average CO2 concentration fluctuated within the range of 385.61 ppm to 510.30 ppm and an average light intensity of 94.62 to 240.45 W/m². W/m². This study assessed various growth parameters, such as plant Height, leaf growth, stem diameter, leaf spacing, leaf count, leaf area, and inflorescence count per plant. The key results of this study revealed the Progressive Growth Report (PGR), predicting daily potential growth. Rates: plant height (2.86 to 3.81 cm/day), mature old leaf growth (0.003988 m2/day), middle younger leaf growth (0.008733 m2/day), top nascent leaf growth (0.010722 m2/day), three to five leaves per week and one inflorescence per week. Additionally, accidental observations were noted. unusual plant growth and yield responses due to varied plant postures in the greenhouse. A non-significant interaction was found between fruit keeping quality (Shelf days), fruit height, fruit diameter, and inflorescence number. The results of this study offer valuable insights for optimizing greenhouse operations, aiming to improve cherry tomato yields and quality while fostering environmental sustainability. An analysis of variance was used to statistically analyze the presented results at a confidence level of p < 0.05.

By analysing big data collected from 1990 to 2017 on the consumption behaviours of men and women living alone and in heterosexual couples in Switzerland, we classified 75 food items in terms of their consumption within couple versus single households. We defined and quantified the gender dominance exhibited in the food purchasing activities of couples. Our results showed that to form consumption of couples, the average consumption of single women weighted 0.6, while that of men weighted 0.38. In addition, couples were found to consume more drinks and pricier foods than singles. Our findings span various areas, including the socioeconomics of food, food choice, social eating, gender power, eating behaviour and population and consumer studies. The robustness of the findings may be validated for other countries and cultures, and the findings may be of interest to researchers from various fields.

Following the Russian invasion of Ukraine, the European Union (EU) lifted import tariffs for Ukrainian commodities to maintain Ukrainian exports to the world market. This led to a considerable decrease of prices for cereals and oilseeds in affected Member States. The European Commission has allocated 56 million euros to farmers in Bulgaria, Poland and Romania to compensate them for losses caused by this opening of the EU. This money has been supplemented by another 56 million euros from national budgets. As the funds were insufficient to fully compensate farmers for their losses, the three Member States had to define selective criteria when deciding on the distribution of the funds. Bulgaria opted for acreage‐based compensation payments for sunflower producers, and Romania chose to support farmers storing wheat, thereby excluding smaller producers without storage facilities. Poland compensated a large range of crop producers but cut the amount paid to the largest farms. A comparison of these three approaches is a good case in point for demonstrating the interplay between emergency relief and political priorities of national governments.

Sequence studies of the entire exome and transcriptome of lymphoma tissues have identified MYD88 and PIM1 as involved in the development and oncogenic signaling. We aimed to determine the frequency of MYD88 and PIM1 mutations, as well as their expressions in conjunction with the clinicopathological parameters identified in mature large B-cell non-Hodgkin lymphomas. The ten-year retrospective study included 50 cases of mature large B-cell lymphoma, diagnosed at the Pathology Department of the Emergency County Hospital of Constanţa and Săcele County Hospital of Brasov. They were statistically analyzed by demographic, clinicopathological, and morphogenetic characteristics. We used a real-time polymerase chain reaction technique to identify PIM1 and MYD88 mutations as well as an immunohistochemical technique to evaluate the expressions of the 2 genes. Patients with lymphoma in the small bowel, spleen, brain, and testis had a low-performance status Eastern Cooperative Oncology Group ( P = .001). The Eastern Cooperative Oncology Group performance status represented an independent risk factor predicting mortality (HR = 9.372, P < .001). An increased lactate dehydrogenase value was associated with a low survival ( P = .002). The international prognostic index score represents a negative risk factor in terms of patient survival (HR = 4.654, P < .001). In cases of diffuse large B-cell lymphoma (DLBCL), immunopositivity of MYD88 is associated with non-germinal center B-cell origin ( P < .001). The multivariate analysis observed the association between high lactate dehydrogenase value and the immunohistochemical expression of PIM1 or with the mutant status of the PIM1 gene representing negative prognostic factors (HR = 2.066, P = .042, respectively HR = 3.100, P = .004). In conclusion, our preliminary data suggest that the oncogenic mutations of PIM1 and MYD88 in our DLBCL cohort may improve the diagnosis and prognosis of DLBCL patients in an advanced stage.

Goji berries, long valued in Traditional Chinese Medicine and Asian cuisine for their wide range of medicinal benefits, are now considered a ‘superfruit’ and functional food worldwide. Because of growing demand, Europe and North America are increasing their goji berry production, using goji berry varieties that are not originally from these regions. European breeding programs are focusing on producing Lycium varieties adapted to local conditions and market demands. By 2023, seven varieties of goji berries were successfully registered in Romania, developed using germplasm that originated from sources outside the country. A broader project focused on goji berry breeding was initiated in 2014 at USAMV Bucharest. In the present research, five cultivated and three wild L. barbarum genotypes were compared to analyse genetic variation at the whole genome level. In addition, a case study presents the differences in the genomic coding sequences of BODYGUARD (BDG) 3 and 4 genes from chromosomes 4, 8, and 9, which are involved in cuticle-related resistance. All three BDG genes show distinctive differences between the cultivated and wild-type genotypes at the SNP level. In the BDG 4 gene located on chromosome 8, 69% of SNPs differentiate the wild from the cultivated genotypes, while in BDG 3 on chromosome 4, 64% of SNPs could tell the difference between the wild and cultivated goji berry. The research also uncovered significant SNP and InDel differences between cultivated and wild genotypes, in the entire genome, providing crucial insights for goji berry breeders to support the development of goji berry cultivation in Romania.

Background: Visceral leishmaniasis is a vector-borne immune-related disease that manifests mainly by lowering of immune protective T-helper-1 cells and onset of diseasepromoting T-helper-2 cells therefore the treatment of visceral leishmaniasis depends on boosting the immune status of the host. Methods: In this study, two traditional medicinal plants Withania somnifera and Tinospora cordifolia were selected, and their whole plant extracts were used for treating visceral leishmaniasisinfected BALB/c mice. Observing the case of immune suppression and balance of Th-1/Th-2 dichotomy during visceral leishmaniasis in mind, the efficacy of these combined herbal drugs against visceral leishmaniasis infected mice was evaluated by monitoring the restoration of Thelper- 1 type protective immune response. Results: To evaluate the effectiveness of these drugs against visceral leishmaniasis, reactive nitrogen species and reactive oxygen species were measured. Biochemical parameters were also performed from blood serum samples during this study, and normalized results were obtained in visceral leishmaniasis-infected mice treated with Withania somnifera and Tinospora cordifolia subgroup. The Amphotericin B treated subgroup was considered as standard positive control during the experiment. Conclusion: A combination of herbal drugs resulted in a successful clearance of Leishmania parasite as well as increased immune protective T-helper-1 cells, suggesting these drugs as efficient antileishmanial agents.

Male infertility is frequently caused by idiopathic or unexplained reasons, resulting in an increase in demand for assisted reproductive technologies. In buffaloes, more than in other animals due to reproductive hardiness, successful fertilization needs spermatozoa to effectively transit the female reproductive system to reach the oocyte. This mechanism naturally picks high-quality sperm cells for conception, but when artificial reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, or intrauterine insemination are utilized, alternative techniques of sperm selection are necessary. Currently, technology allows for sperm sorting based on motility, maturity, the lack of apoptotic components, proper morphology, and even sex. This study provides current knowledge on all known techniques of sperm cell sorting in buffaloes, evaluates their efficiency, and discusses the benefits and drawbacks of each approach.

There is great interest in the development of prosthetic limbs capable of complex activities that are wirelessly connected to the patient’s neural system. Although some progress has been achieved in this area, one of the main problems encountered is the selective acquisition of nerve impulses and the closing of the automation loop through the selective stimulation of the sensitive branches of the patient. Large-scale research and development have achieved so-called “cuff electrodes”; however, they present a big disadvantage: they are not selective. In this article, we present the progress made in the development of an implantable system of plug neural microelectrodes that relate to the biological nerve tissue and can be used for the selective acquisition of neuronal signals and for the stimulation of specific nerve fascicles. The developed plug electrodes are also advantageous due to their small thickness, as they do not trigger nerve inflammation. In addition, the results of the conducted tests on a sous scrofa subject are presented.

Maintaining a rural-urban balance is absolutely necessary in the context of the challenges related to food security and environmental protection as well as the perspectives of urban agglomeration. This paper highlighted the impact of the main events from the last 30 years on the rural population. This study used the vector autoregressive model (VAR) to investigate the estimates and analyse the dynamic impact of innovations on the system of variables. Key issues that influenced certain periods in the analyzed interval were highlighted, which clearly show the impact on the analyzed variables using variance decomposition. The cost of living in rural areas is increasing, so more and more inhabitants give up growing certain crops or raising certain animals, thus having to search for food to survive, leading to additional wage income to cover these costs.

The increasing incidence of diabetes has prompted the need for new treatment strategies, including natural products that reduce glycemia values. This work examined the in vitro and in vivo antihyperglycemic effects of new metabiotics derived from Boletus edulis extracts. The metabiotics were obtained from 100% B. edulis, and two other products, CARDIO and GLYCEMIC, from Anoom Laboratories SRL, which contain other microbial species related to B. edulis. Our in vitro investigations (simulations of the microbiota of patients with type 2 diabetes (T2D)) demonstrated that B. edulis extracts modulate the microbiota, normalizing its pattern. The effects were further tested in vivo, employing a mouse model of T2D. The tested extracts decreased glycemia values compared to the control and modulated the microbiota. The metabiotics had positive effects on T2D in vitro and in vivo, suggesting their potential to alleviate diabetes-associated microbiota dysbiosis.

SCDP-Nucet has an essential activity in aquaculture-especially in the genetic improvement of cultured carp and the preservation and usage of freshwater fish genotypes using advanced integrated technologies for fish farming. Climate changes have a crucial role in fish farming because they negatively affect the water bodies and the fish metabolism. This study aims to monitor the water quality of ponds associated with weather data during two years (i.e., 2022 and 2023), from May to September. The climate change implications on fish habitats were also discussed.

Differentiation of amniotic fluid stem cells (AFSCs) into multiple lineages is controlled by epigenetic modifications, which include DNA methylation, modifications of histones, and the activity of small noncoding RNAs. The present study investigates the role of miRNAs in the differentiation of AFSCs and addresses how their unique signatures contribute to lineage-specific differentiation. The miRNA profile was assessed in AFSCs after 4 weeks of endothelial and muscular differentiation. Our results showed decreased expression of five miRNAs (miR-18a-5p, miR-125b-5p, miR-137, miR-21-5p, and let-7a) and increased expression of twelve miRNAs (miR-134-5p, miR-103a-3p, let-7i-5p, miR-214-3p, let-7c-5p, miR-129-5p, miR-210-3p, let-7d-5p, miR-375, miR-181-5p, miR-125a-5p, and hsa-let-7e-5p) in endothelial progenitor cells (EPCs) compared with undifferentiated AFSCs. AFSC differentiation into smooth muscle revealed notable changes in nine out of the 84 tested miRNAs. Among these, three miRNAs (miR-18a-5p, miR-137, and sa-miR-21-5p) were downregulated, while six miRNAs (miR-155-5p, miR-20a-5p, let-7i-5p, hsa-miR-134-5p, hsa-miR-214-3p, and hsa-miR-375) exhibited upregulation. Insights from miRNA networks promise future advancements in understanding and manipulating endothelial and muscle cell dynamics. This knowledge has the potential to drive innovation in areas like homeostasis, growth, differentiation, and vascular function, leading to breakthroughs in biomedical applications and therapies.
