Phosphonate-based fungicides are believed to control fungal diseases while also supplying nutrients to plants. However, opinions differ on whether they truly serve as nutrients for plants, and the residues of their transformation products have not yet been thoroughly evaluated or mathematically characterized. To address this gap, this study analyzed data from a two-factorial experiment investigating the effects of Agrifos 400 (potassium phosphonate) application. The experiment involved two soil types: red basalt soil and an organically enriched soil. Three-month-old pepper plants (Piper nigrum L.) were treated with Agrifos at application intervals of 10 and 20 days. The soils were inoculated with pathogenic Pythium spp., known to cause root rot diseases in plants. The soil chemical concentrations were analyzed every ten days, while plant growth parameters (height and leaf numbers) were recorded weekly. A mathematical model describing the fate of Agrifos transformation products was developed and parameterized using this experimental data. The results from the two-month experiment indicated that Agrifos did not enhance plant growth during this period. However, it led to a dramatic increase in soil phosphate (PO₄³⁻) levels, which could pose environmental risks. Despite this, the developed mathematical model demonstrated strong explanatory power, accurately capturing the observed data trends. Consequently, future research should consider integrating this model into broader biogeochemical cycle simulations, particularly those that incorporate chemical transport through soil water. Such integration would support more accurate predictions of the long-term environmental impacts of phosphonate-based products like Agrifos. Full article

Background and Clinical Significance: Carotid stump syndrome (CSS) is a rare and unexpected cause of recurrent ischemic ipsilateral events in the carotid vascular territory despite the demonstrated occlusion of the internal carotid artery (ICA). It is believed to be caused by microemboli due to turbulent blood flow in the patent stump of the occluded ICA that passes through anastomotic channels and retrograde flow into the middle cerebral artery circulation. Case Presentation: We describe the case of a 65-year-old male patient who suffered multiple concurrent transient ischemic attacks (TIAs) with a totally occluded ipsilateral ICA revealed by computed tomography angiography (CTA). He was diagnosed with CSS, which required the safest therapeutic approach. A further investigation with digital subtraction angiography (DSA) was performed, and a trickle of blood flow was observed in the reportedly occluded ICA. The diagnosis of a true ICA occlusion was withdrawn, and a diagnosis of pseudo-occlusion was established, affecting the final treatment strategy. Therefore, the patient underwent an ipsilateral carotid endarterectomy (CEA), and he has remained asymptomatic since then. Conclusions: The differentiation between a pseudo-occlusion and a true ICA occlusion is essential in promptly managing acute recurrent ipsilateral ischemic strokes in the carotid vascular territory. A further investigation with DSA in cases with a totally occluded ICA using CTA is essential for excluding pseudo-occlusions in ipsilaterally symptomatic patients. Full article

Objectives: Oropharyngeal carcinoma is experiencing an increase in incidence and can easily metastasize to the cervical lymph nodes. Therefore, evaluating the tumor boundary and lymph node metastasis before treatment is critical. Both CT and MR may have limitations in describing the specific boundaries of oropharyngeal tumors. To date, no research has applied PET/MR imaging to patients with only oropharyngeal carcinoma and verified its diagnostic value. The aim of our study was to evaluate the diagnostic value of PET/MR in patients with oropharyngeal carcinoma. We prepared PET/MR for comparison with CT/MR for T and N staging, with the aim of exploring the relationship between the imaging parameters and different biological factors. Methods: This was a retrospective, observational study. In total, 13 patients (11 males and 2 females) with oropharyngeal tumors who underwent FDG PET/MR and enhanced CT/MR from July 2021 to December 2022 were retrospectively analyzed. Cohen’s kappa coefficient and the McNemar test were used to compare the consistencies and diagnostic values of FDG PET/MR and enhanced CT/MR imaging in relation to primary tumors and cervical lymph node metastases. Various specific parameters of FDG PET/MR were included in the statistics. Spearman correlation coefficients were used to analyze the relationship between the parameters and the tumor stage, the degree of differentiation, p16 expression, Ki67 expression, and serological tumor markers. Results: The average age of the patients was 61.54 ± 6.62 years old. Preoperative imaging demonstrated good consistency between FDG PET/MR and enhanced CT and MR for the diagnosis of clinical T stage. A total of seven patients underwent surgery directly. Overall, 231 cervical lymph nodes were dissected. Compared to the postoperative histopathological results, PET/MR was significantly more sensitive than enhanced CT/MR imaging (78.57% vs. 50.00%, p < 0.05; 78.57% vs. 64.29%, p < 0.05, respectively). Also, PET/MR showed more accuracy in diagnosing metastatic lymph nodes, but without significance. Combined with PET/MR-specific parameters, the SUV, TLG, and the MTV were found to be higher in the patients with more advanced stages of cancer and lower in those with p16-positive tumors. In addition, they were found to be positively correlated with the level of serum CEA. Conclusions: This is the first study to evaluate the clinical diagnostic value of PET/MR in patients with oropharyngeal carcinoma. We believe that PET/MR has more advantages in describing tumor boundaries. It is more sensitive or even more accurate for the evaluation of metastatic cervical lymph nodes. Full article

In the era of Artificial Intelligence, the magic of achieving results at the “speed of light” for tasks that until recently required a lot of work and effort shocks, arouses enthusiasm and generates fears at the same time. Therefore, starting from this reality of our days, we proposed within the current research to study the relationship between the factors of technostress (techno-overload, techno-invasion, techno-complexity, techno-insecurity, techno-uncertainty) perceived as a result of the implementation of AI at the societal level and the quality of life, filtering the relationship through the “lens” of the positive and negative affect mediators. The mediation analyses, conducted on a sample of 217 adult Romanian citizens (18–62 years old), suggested that although AI-related technostress does not directly influence quality of life, it has a significant indirect impact through affective traits—general tendencies to frequently experience positive or negative emotions. This indicates that technostress contributes to variations in quality of life by influencing emotional experiences, which mediate the relationship. These findings emphasize not only the absence of a direct effect, but also the importance of the indirect pathway in understanding how individuals are affected by AI-related stress. We believe that the results of the current study can be equally useful in raising awareness of the psychological mechanisms responsible for the quality of life and in understanding the importance of implementing official programs, both technically, regarding the development of skills to understand and work with AI, and psychological support programs, considering the management of emotions, with reference to this technology.

Background and Clinical Significance: Statins are a widely used drug class associated with a plethora of muscular side effects ranging from the subclinical elevation of creatine kinase to fulminant rhabdomyolysis. Cardiac myopathy secondary to statin treatment is rare and was recently reported as a part of statin-induced necrotizing autoimmune myopathy (SINAM). Its occurrence outside of this context is still debated. Case Presentation: We present the case of a 60-year-old male who developed atorvastatin-induced rhabdomyolysis, without associated hydroxymethyl glutaryl coenzyme A reductase (HMGCR) antibodies, with clinical findings of cardiac failure and severe ECG anomalies. The symptoms slowly regressed with statin withdrawal, and the patient made a full recovery. We discuss the recently proposed statin-associated cardiomyopathy (SACM) and the possible mechanisms. We compare our case to the three other cases of statin-induced cardiac myositis found in the literature. Conclusions: We believe that in vulnerable patients, as was our case, statins can determine significant subacute cardiac toxicity. This would seem to occur in the context of severe skeletal muscle injury, probably due to higher metabolic resistance on the part of the myocardium. Also, the available evidence suggests myocardial involvement should be actively investigated in SINAM patients, preferably by cardiac MRI. Full article

There is a widespread belief today, primarily among the agnostics and atheists, and even among the not so active believers, that all forms of religious belief, including Christian Catholicism, should remain outside the political realm, limited to private spirituality. This paper thematises, in the context of “positive laicity”, the way the Catholic Church changed its understanding of politics after the Second Vatican Council, regarding the involvement of believers, as serving the common good in a plural society. Using conciliar and post-conciliar documents as sources for reflection and argumentation, this paper outlines eight theological and anthropological assumptions regarding Catholic involvement in politics within the context of the 21st century, adapting the (post-)conciliar thought to the conditions of today’s globalised world. For Christians to do well in this responsible assignment, the starting point is Jesus Christ, both in the historical and in the cosmic project of God’s world in the making, expressed in the Old Testament as the arrival of God’s Kingdom. This article is methodologically limited, as the title states, to recognise and briefly sketch the content of a few basic theological–anthropological assumptions of Christian participation in politics, without going into the history of the issue, as well as to the authors who dealt with it in various aspects. In conclusion, we notice that the manner of religious action in politics described in this way presupposes that the believer has already left the state of infancy within his ecclesial community and is ready to make decisions within the political community based on his faith, competences and conscience, without clerical tutelage and obstruction.

The Wolf isotopic response (WIR) refers to the development of cutaneous lesions in areas of previously healed but unrelated skin disease. While most are observed in healed herpes zoster, WIR has been reported in various other contexts. Affected areas are believed to exhibit immune dysregulation, lymphatic dysfunction, and altered neuromediator activity, increasing susceptibility to inflammatory, neoplastic, and infectious conditions. This phenomenon aligns with the broader concept of the “immunocompromised district”, which also encompasses the Koebner phenomenon and its reverse. Herein, we present the case of a 96-year-old woman who developed multiple cysts and comedones at the site of a resolved herpes zoster. Due to persistent and refractory inflammation, curettage was performed, and histopathological examination revealed angiosarcoma with a pseudolymphomatous reaction interspersed among the cysts. The coexistence of multiple types of WIR is rare but not unprecedented, highlighting the importance of recognizing the diverse pathologic conditions that can arise in such settings. In this review, we explore the historical evolution of terminology used to describe lesions in vulnerable skin areas and related phenomena. We also provide an updated overview of current pathogenic theories and present a comprehensive compilation of postherpetic reactions reported to date. Full article

As a cancer patient and Old Testament scholar, I will offer my thoughts on how the Old Testament speaks theologically and practically to the human condition in relation to deadly disease. This essay follows (in broad strokes) my lifelong formative theological and ecclesiastical experiences with healing in Scripture and among believers. Episodes in my personal experience will be followed by theological exegesis related to perspectives and passages in the Old Testament that I find pertinent for the topic of cancer or any life-threatening illness or injury in the life of Christians whose faith is connected to the Bible as divine revelation. In particular, and mainly, texts related to wisdom in the Old Testament (Ecclesiastes to be exact) are considered. This is followed by reflections on passages that appear to offer guarantees of healing and then a conclusion that draws personal but also, hopefully, appropriate universal lessons about sickness and mortality from the Hebrew Bible.

Background/Objectives: Research on cashmere goat coat color is crucial for optimizing cashmere goat breeds and increasing their economic value. To identify key genes associated with the formation of cashmere goat coat color and to provide molecular markers for breeding purposes, three healthy, 3-year-old does with similar weights and distinct coat colors—white, black, and light brown—were selected. Methods: Skin samples were collected for transcriptome sequencing, and bioinformatics methods were applied to screen for differentially expressed genes (DEGs) in the skin of cashmere goats with varying coat colors. Real-time fluorescence quantitative PCR (qRT-PCR) and immunofluorescence were subsequently conducted to examine the expression patterns of these DEGs. Results: The results showed that a total of 1153 DEGs were identified across the three groups of cashmere goats. According to GO and KEGG analyses, these DEGs were involved in key biological processes and structures, such as the melanin biosynthetic process (GO:0042438), melanosome membrane (GO:0033162), and melanin biosynthesis from tyrosine (GO:0006583). Employing Cytoscape, a gene interaction network was plotted, highlighting a compact network of DEGs associated with coat color formation. Critical genes identified included TYRP1, TYR, DCT, ASIP, PMEL, LOC102180584, MLANA, TSPAN10, TRPM1, CLDN16, AHCY, LOC106503350, and LOC102175263. qRT-PCR and fluorescence immunohistochemistry further determined that TYRP1, TYR, DCT, and PMEL expression levels were high in black goats (BGs), while ASIP and AHCY expression levels were high in white goats (WGs). The expression levels of these six genes in light brown goats (RGs) were intermediate between those in BGs and WGs. Conclusions: TYRP1, TYR, DCT, and PMEL were believed to play pivotal roles in the formation of black coat color, while ASIP and AHCY regulated the formation of white coat color in cashmere goats.

Historically, EGFR and KRAS mutations were believed to be mutually exclusive. However, over the past few years, there have been emerging case reports showing the co-existence of both mutations in a single case. The majority of these co-occurring alterations were detected in samples collected from patients with resistance to tyrosine kinase inhibitor (TKI) treatment, indicating a potential functional role in driving resistance to therapy. These co-occurring tumor genomic alterations are not necessarily mutually exclusive, and evidence suggests that multiple clonal and sub-clonal cancer cell populations can co-exist and contribute to EGFR TKI resistance. We have reported such a case of concomitant EGFR and KRAS mutation in a 64-year-old female. This case highlights the importance of continuous molecular testing in managing NSCLC, especially in cases with rare mutation profiles. The emergence of new mutations during treatment can significantly impact the course of therapy and patient outcomes. In this case, the detection of both EGFR and KRAS mutations guided the selection of an appropriate targeted therapeutic strategy, including the use of Amivantamab. Full article

Brucellosis is still the most common zoonosis worldwide despite advanced technology and animal husbandry. Since there is still no effective Brucella vaccine for humans, it is crucial to control the disease in ruminants through eradication and vaccination. Although some countries around the world have achieved this circumstance, every country aims to become free of Brucellosis through vaccination, animal movements, and various eradication measures. For this purpose, the Brucella abortus S19 strain has been used safely for about 100 years. However, due to the O-polysaccharide (OPS) antigen in its structure, the antibody response created by the vaccine causes confusion in serological tests. For this purpose, researchers have provided both mucosal immunity and short-term antibody response by using the B. abortus S19 vaccine in conjunctival form instead of subcutaneous form. This study aimed to determine how long the post-vaccination titer levels persisted in animals vaccinated with vaccines from 3 different companies and different routes. In this study, a total of 115 calves aged 3 to 4.5 months were created in five groups, with 23 animals in each group: group 1 (vaccine brand A), group 2 (vaccine brand B), and group 3 (vaccine brand C) received the two-dose conjunctival vaccine, group 4 received the single-dose subcutaneous vaccine (vaccine brand C), and group 5 received the subcutaneous vaccine (vaccine brand C) plus the booster dose conjunctival vaccine (vaccine brand B). Brucellosis antibody titers were monitored each 21 days until the cattle were 26–28 months old. The collected sera were analyzed using the Rose Bengal Plate Test (RBPT), Serum Agglutination Test (SAT), and Complement Fixation Test (CFT), which are the preferred serological methods for Brucellosis eradication plans worldwide. In the conjunctival vaccination groups, only 3 (13%) of the animals in group 1 developed antibody titers one month after vaccination, and there was no antibody response detected against Brucellosis in group 2 and group 3. In animals that were stimulated conjunctivally, the threshold value of 30 International CFT Units (ICFTUs) (for distinguishing between infective titers and vaccination titers) was observed in one animal each in group 1 and group 2 and 0 animal in group 3. It was found that antibody titers turn to Brucellosis negative in all conjunctival vaccine groups at 7 months after vaccination. In groups 4 and 5, the first-month serological screening detected over 30 ICFTUs in 17 (89.47%) animals and 16 (69.5%) animals, respectively. In group 4, CFT titers were found to fall below 30 on the 17th month and 9.3 on the 22nd month. On the 14th month, the CFT titers of group 5 were found to be below 30, and all animals in this group turned negative after the 19th month. It was found that the single dose B. abortus S19 subcutaneous vaccination in calves caused persistent antibodies in 5% of the population. It is believed that persistent and high antibody titers created by subcutaneous vaccines will cause false positivity and create confusion in Brucellosis eradication programs. Therefore, although there is no clear distinction between vaccinated and infected animals, it has been observed that conjunctival Brucellosis vaccines create more stable antibody titers and decrease rapidly compared to subcutaneous vaccines. Based on the results of this study and the advantages of conjunctival vaccines, more effective eradication programs and antibody monitoring can be carried out in vaccinated herds where Brucellosis outbreaks are observed.

The growing body of research on children’s understanding of extraordinary minds has demonstrated that children believe in the persistence of mental functioning after death. However, beyond the continuity of mind, the supernatural conception of death often involves the concept of the disembodied mind, which transcends the constraints of the physical body, possessing supernatural mental capacities. The current study investigated whether children differentiate between a dead agent’s mind and ordinary minds in terms of their perceptual and information-updating capacities. In a location-change false-belief task, which involved a story of a mouse protagonist that was either eaten by an alligator or not, 4- to 6-year-old Korean children (N = 114) were asked about the mental states of the protagonist, an ordinary adult (mom), and God. The results showed (1) older children’s tendency to respond in a way that differentiated (the living) mom from the dead protagonist, (2) an increasing trend of differentiating God’s super-knowingness from ordinary minds with age, and (3) inconclusive evidence regarding children’s differential responses to the dead versus living protagonist. This study suggests that children are not predisposed to view dead agents as possessing a disembodied and supernatural mind, highlighting the importance of cultural learning in the development of such religious concepts.

This case report highlights the use of continuous infusion of meropenem in a 42-year-old septic female patient with periprosthetic infection and end-stage renal disease receiving prolonged intermittent renal replacement therapy (PIRRT). Antibiotic infusion in patients receiving renal replacement therapy has its own peculiarities. There are many studies on the optimal dosing regimen for meropenem in renal dysfunction, but studies on the optimal infusion duration in these patients are limited. The patient was admitted with complaints of wounds, necrosis zones of the right upper limb, restriction of joint movements, and temperature increase up to 38 °C. The patient was treated with a continuous infusion of meropenem 2 g per day receiving renal replacement therapy three times a week (12 h). Also during hospitalization, the patient underwent hip disarticulation and excision of necrotic tissues. The patient was further transferred to a specialized nephrology department for further treatment. We believe that in this clinical case, the use of continuous infusion of meropenem in the complex therapy of sepsis in a patient with CKD undergoing PIRRT sessions helped to lead to clinical improvement in the patient. Further studies are needed. Full article

Background: Acute disseminated encephalomyelitis (ADEM) is a rare, immune-mediated inflammatory disorder of the central nervous system (CNS), typically characterized by the acute onset of multifocal demyelination. The pathogenesis of ADEM remains unclear, but it is believed to be triggered by an autoimmune response, often following viral infections or vaccinations. Case report: This case report describes a 3-year-old child who developed ADEM after receiving two concurrent influenza vaccines: one for seasonal influenza and one for the 2009 H1N1 pandemic. The patient presented with motor regression, mild pleocytosis in cerebrospinal fluid (CSF), and typical MRI findings of ADEM. Steroid pulse therapy resulted in rapid improvement, and the patient recovered fully without sequelae. Results: Although the influenza vaccine has been linked to ADEM in some studies, it remains uncertain whether the simultaneous administration of both vaccines contributed to the onset of ADEM. While influenza vaccines are considered safe and effective by health organizations such as the CDC, data suggest that the incidence of ADEM and other neurological complications is significantly higher after natural influenza infections compared to vaccination. This highlights the importance of vaccination in preventing severe outcomes. Conclusions: This case underscores the importance of monitoring and reporting adverse events following vaccination to refine our understanding of rare complications like ADEM. While simultaneous vaccine administration warrants further research, the benefits of vaccination in preventing severe complications from natural infections far outweigh the risks. Continued vigilance and improved surveillance systems are essential for maintaining public confidence in vaccination programs. Full article

Agroforestry improves the stability and productivity of agro-ecosystems and reduces environmental pressures, making it extremely flexible and useful in a variety of physical and social contexts. This practice is crucial to farmers’ livelihoods on both an ecological and economical level. Using an interview schedule, data were gathered from 170 heads of rural families who were chosen at random. Of the responders, the majority (77.5%) were young (25 to 40 years old). Of those who had completed more than five years of schooling, only 46.7% were literate, while a sizable majority (53.3%) were illiterate. For the vast majority of responders (62.4%), farming was their primary source of income. Given that over 54% of the respondents only owned up to five acres of land, small farming was extremely common. The majority (61.3%) were considered poor with a monthly income of less than PKR 18,000. “good source of fuel wood” was placed at the top (mean = 3.1%) when it came to the effect of agroforestry on the food security of rural households. One of the main obstacles was having a small land holding (mean = 2.52). The majority of respondents believed that the primary benefit of agroforestry was a reduction in soil loss. The amount of land held, income source, and educational attainment all significantly correlated with the perception of poverty. The study found that the best way of sustainably assuring food security in the study area and satisfying rural residents’ needs for food for extended periods of time is to incorporate agroforestry into the current farming system.
