The quest for surgical advancements regarding the enhancement of the submental and cervicofacial regions has witnessed a remarkable upsurge in recent years. Informed patients are actively seeking sophisticated plastic surgery techniques to achieve comprehensive rejuvenation in these specific areas. Common complaints expressed by these patients include sagging of the jawline, the emergence of deep perioral wrinkles, and the formation of “marionette lines” within the lower third of the face. Furthermore, the manifestation of age-related signs, including neck laxity, submental adipose accumulation, “witch’s chin” deformity, and weakened platysma musculature, are common within this anatomical region. This literature review aims to summarize recent technical improvements, historical evolution, indications, postoperative care, and challenges for facial rejuvenation of the lower third of the face and neck. The application of minimally invasive procedures as part of a comprehensive approach for an aging face will also be discussed. In this article, an extensive search of the available literature was conducted using leading databases, including PubMed and MEDLINE, with the keywords “neck lift”, “platysmaplasty”, “facial rejuvenation”, “medial platysmaplasty”, “lateral platysmaplasty”, “neck rejuvenation”, and “cervicofacial rejuvenation”.

‘Candidatus Phytoplasma ulmi’ (16SrV-A) is the causal agent of elm yellows (EY), a lethal and/or decline disease of several Ulmus (elm) species and hybrids in North America and Europe. In this study, field observations and PCR assays were used to detect phytoplasma infections in diseased U. minor, U. pumila and U. glabra trees in southern Italy. Also, a multigene sequence analysis employing various less conserved genes was carried out to explore the genetic variation in detected strains. All the symptomatic elm trees tested were infected with ‘Ca. Phytoplasma ulmi’. No other phytoplasmas or variants could be detected. Although ‘Ca. Phytoplasma ulmi’ was already known to occur in southern Italy on European field elm, the current work expands the information on the presence, disease incidence and severity, plant host range and molecular aspects of EY phytoplasma strains occurring in southern Italy. In addition, this is the first report from Italy on the molecular characterization of EY phytoplasma strains through map, imp and groEL gene sequence and phylogenetic analyses. Among the newly detected EY phytoplasma strains, some proved distantly related to each other and to other previously characterized EY phytoplasma strains within the genes examined. This implies the presence of distinct taxonomic entities within the material examined. The occurrence of different strains was not linked to the biological traits and geographical distribution. However, the data obtained may provide a basis for further studies aimed at elucidating several other unknown aspects of the EY agent, knowledge of which is essential for effective disease management and control strategies. The results of the current work also show that the EY phytoplasma is particularly widespread in southern Italy and is of considerable economic and ecological relevance. Full article

The thymidylate kinase (tmk) gene is indispensable for the proliferation and survival of phytoplasma. To reveal the molecular variation and phylogeny of the tmk genes of Candidatus phytoplasma ziziphi, in this study, the tmk genes of 50 phytoplasma strains infecting different resistant and susceptible jujube cultivars from different regions in China were amplified and analyzed. Two sequence types, tmk-x and tmk-y, were identified using clone-based sequencing. The JWB phytoplasma strains were classified into three types, type-X, type-Y, and type-XY, based on the sequencing chromatograms of the tmk genes. The type-X and type-Y strains contained only tmk-x and tmk-y genes, respectively. The type-XY strain contained both tmk-x and tmk-y genes. The type-X, type-Y, and type-XY strains comprised 42%, 12%, and 46% of all the strains, respectively. The type-X and type-XY strains were identified in both susceptible and resistant jujube cultivars, while type-Y strain was only identified in susceptible cultivars. Phylogenetic analysis indicated that the tmk genes of the phytoplasmas were divided into two categories: phylo-S and phylo-M. The phylo-S tmk gene was single-copied in the genome, with an evolutionary pattern similar to the 16S rRNA gene; the phylo-M tmk gene was multi-copied, related to PMU-mediated within-genome transposition and between-genome transfer. Furthermore, the phylogenetic tree suggested that the tmk genes shuttled between the genomes of the Paulownia witches’ broom phytoplasma and JWB phytoplasma. These findings provide insights into the evolutionary and adaptive mechanisms of phytoplasmas. Full article

Even though classic literature has cultural and educational value in heritage education, students often have trouble becoming interested because of the archaic language, a lack of good learning materials, the idea that the literature is not relevant, and complicated plots. This research aims to enhance heritage education by identifying barriers and drivers in youth engagement with classic Thai literature and exploring how Universal Design for Learning (UDL) principles could be applied to increase motivation in learning classic literature through multimedia. Ten interviews with experts, 100 on-site questionnaires filled out by students aged 15–25 years, and a multimedia e-book were used together in this mixed-methods study. As a case study, the researchers asked both experts and students to read the Thai classic poem “Phra Aphai Mani: Escaping from the Sea Witch” and make suggestions for how it could be better. The results show that there are barriers to heritage education, such as ‘the story is not connected to the present’ (mean = 4.52/5), ‘archaic vocabulary and language barriers’ (mean = 4.36/5), and ‘learning materials’ (mean = 4.25/5). Surprisingly, Thai students showed more positive attitudes towards literature courses than expected based on international trends. Key drivers for enhancing heritage education include ‘classic literature in modern, easy-to-read language’ (mean = 4.65/5), ‘including multimedia’ (mean = 4.58/5), ‘the plot/story adapted to the current era’ (mean = 4.50/5), and ‘new presenting technologies’ (mean = 4.49/5). Next, as an innovative way to improve heritage education, this study developed a free e-book titled “Phra Aphai Mani: Escaping from the Sea Witch”, which includes motion graphics and other multimedia elements. This research contributes to knowledge by demonstrating how UDL can be applied to classic literature within heritage education, enhancing understanding of student needs, and creating more effective, inclusive multimedia teaching methods for preserving and transmitting cultural heritage.

This contribution reconstructs the reflection on witches of Johannes Trithemius (1462–1516), a German Benedictine who took up the pen on several occasions to declare against the spread of witchcraft and the need to solve this problem. The method adopted is to understand Trithemius’ thought from the analysis of his own works, specifically the Antipalus maleficiorum (1505–1508), the Liber octo quaestionum (1515) and what can be known of the De daemonibus (1507–1514). What will emerge will be an articulate reflection, which re-proposes the doctrine of the Malleus maleficarum (1486) enriched with original elements often drawn from popular superstitions. Thus, Trithemius proposes artifices to be immune from witches (e.g., apotropaic amulets) and provides specific indications on how to cure evil spells (exorcism), extending the dissertation to broader issues, such as the gender question, the relationship between witches and children (e.g., sacrifices, proselytes, victims) and developments in exorcism practice.

Composite polymer membranes were obtained using the so-called dry phase inversion and were used for desalination of diluted saline water solutions by pervaporation (PV) method. The tests used a two-layer backing, porous, ultrafiltration commercial membrane (PS20), which consisted of a supporting polyester layer and an active polysulfone layer. The active layer of PV membranes was obtained in an aqueous environment, in the presence of a surfactant, by cross-linking a 5 wt.% aqueous solution of polyvinyl alcohol (PVA)—using various amounts of cross-linking substances: 50 wt.% aqueous solutions of glutaraldehyde (GA) or citric acid (CA) or a 40 wt.% aqueous solution of glyoxal. An ethylene glycol oligomer (PEG 200) was also used to prepare active layers on PV membranes. Witch its help a chemically cross-linked hydrogel with PVA and cross-linking reagents (CA or GA) was formed and used as an active layer. The manufactured PV membranes (PVA/PSf/PES) were used in the desalination of water with a salinity of 35‰, which corresponds to the average salinity of oceans. The pervaporation method was used to examine the efficiency (productivity and selectivity) of the desalination process. The PV was carried at a temperature of 60 °C and a feed flow rate of 60 dm³/h while the membrane area was 0.005 m². The following characteristic parameters of the membranes were determined: thickness, hydrophilicity (based on contact angle measurements), density, degree of swelling and cross-linking density and compared with the analogous properties of the initial PS20 backing membrane. The physical microstructure of the cross-section of the membranes was analyzed using scanning electron microscopy (SEM) method. Full article

Paulownia species not only have significant economic benefits but also show great potential in ecological conservation. However, they are highly susceptible to phytoplasma infections, causing Paulownia witches’ broom (PaWB), which severely restricts the development of the Paulownia industry. Salicylic acid (SA) plays a crucial role in plant disease resistance. However, there have been no reports on the effect of SA on PaWB. Due to the properties of SA, it may have potential in controlling PaWB. Based on the above speculation, the prevention and therapeutic effect of SA on PaWB and its effect on the PaWB-infected Paulownia transcriptome and proteome were studied in this work. The results indicated that 0.1 mmol/L was the optimal SA concentration for inhibiting the germination of Paulownia axillary buds. In terms of resistance physiological indicators, SA treatment significantly affected both Paulownia tomentosa infected (PTI) seedlings and Paulownia fortunei infected (PFI) seedlings, where the activities of peroxidase (POD) and superoxide dismutase (SOD) were enhanced. Malondialdehyde (MDA), O₂⁻, and H₂O₂, however, were significantly reduced. Specifically, after SA treatment, SOD activity increased by 28% in PFI and 25% in PTI, and POD activity significantly increased by 61% in PFI and 58% in PTI. Moreover, the MDA content decreased by 30% in PFI and 23% in PTI, the H₂O₂ content decreased by 26% in PFI and 19% in PTI, and the O₂⁻ content decreased by 21% in PFI and 19% in PTI. Transcriptomic analysis showed that there were significant upregulations of MYB, NAC, and bHLH and other transcription factors after SA treatment. Moreover, genes involved in PaWB-related defense responses such as RAX2 also showed significant differences. Furthermore, proteomic analysis indicated that after SA treatment, proteins involved in signal transduction, protein synthesis modification, and disease defense were differentially expressed. This work provides a research foundation for the prevention and treatment of PaWB and offers references for exploring anti-PaWB methods. Full article

This article investigates the factors that provoked the trial and death sentence of four witches in Bologna in 1559. That is, it aims to elucidate how a witch hunt (albeit a small one) was triggered in a context where demonology was present, but the persecution of witchcraft had been kept at a relatively moderate level (and continued to be so after that). Scholarly contributions on witchcraft and witch hunts are now innumerable, but in general, scholars have focused on the social relations between the alleged witches and the community in which they lived, on the theological culture of the judges, or even on the deep roots of the sabbath. An analysis of a series of trials for magical and superstitious practices held in Bologna shortly before the 1559 convictions reveals how it was possible to move from simple sorcery to actual witchcraft. This transition was accomplished both because of the malefic nature of some of the spells practiced by the defendants and because of the intervention of diocesan judges who, for various reasons, were more determined than their predecessors to prosecute witchcraft harshly. Although the link between simple superstition and witchcraft has already been explored to some extent, it emerges with particular clarity in these events. Full article

Between the 16th and 17th centuries, the conservative characteristic of rural environments and mountain communities represented one of the main worries of the Larian Church, which, despite the work of reform of religious customs undertaken by the order of preachers in the late Middle Ages (not unrelated to the genesis of the accusation of diabolic witchcraft), it found itself confronted with the shortcomings (from the interference of the laity in religious life to suspicious devotions via the mixture of the sacred and magical animistic legacies) originating from decades of neglect in the management of valley parishes and the laxity of the secular clergy. This concern had to be reconciled, from the first decades of the sixteenth century onward, with the need to counter the Protestant presence. The “singular” way in which diocesan ordinaries sought in the aftermath of the Tridentine Council to re-establish orthopraxy in the only diocese in the peninsula subject to secular authorities of the Reformed faith, and in which an Italophone Protestant community was permanently present for several decades, represents an important case study for understanding the anomaly of the local bishop’s courts (and the inquisition) transformed during this time from bitter enemies of the secta strigiarum into “witch lawyers”, and for illuminating the deeper reasons for the limits of the fight against superstitions in the entire peninsula.

Cucumber plants (Cucumis sativus) displaying symptoms of phyllody, sterility, and flower virescence were observed in fields located in the Dianbai district of Guangdong province, China. Total DNA was extracted from the symptomatic plants; this was followed by molecular detection using a set of universal phytoplasma primer pairs, R16mF2/mR1, P1/P7, and SecYF1(II)/SecYR1(II). This resulted in the PCR amplification of products corresponding to expected sizes of 1.4 kb, 1.8 kb and 1.7 kb, respectively. The 16S rDNA sequence obtained exhibited 100% similarity with the eggplant phyllody phytoplasma, the ‘Cleome rutidosperma’ witches’ broom phytoplasma, and the ‘Desmodium ovalifolium’ witches’ broom phytoplasma strain DeOWB, all of which belong to the 16SrII group. Phylogenetic analysis, based on the 16S rDNA gene and SecY gene sequences, confirmed the close affiliation of the detected phytoplasma isolate, tentatively designated as cucumber phyllody phytoplasma (CuPh) China isolate, with the 16SrII-A subgroup. Additionally, virtual restriction fragment length polymorphism (RFLP) analysis of the 16S rDNA sequence revealed a pattern that was identical to that of the 16SrII-A subgroup. This is the first report of cucumber phyllody phytoplasma in China. Full article

Cassava witches’ broom disease (CWBD) is one of the most devastating diseases of cassava (Manihot esculenta Crantz), and it threatens global production of the crop. In 2017, a phytoplasma, Candidatus Phytoplasma luffae (Ca. P. luffae), was reported in the Philippines, and it has been considered as the causal agent, despite unknown etiology and transmission of CWBD. In this study, the nationwide occurrence of CWBD was assessed, and detection of CWBD’s pathogen was attempted using polymerase chain reaction (PCR) and next-generation sequencing (NGS) techniques. The results showed that CWBD has spread and become severe, exhibiting symptoms such as small leaf proliferation, shortened internodes, and vascular necrosis. PCR analysis revealed a low phytoplasma detection rate, possibly due to low titer, uneven distribution, or absence in the CWBD-symptomatic cassava. In addition, NGS techniques confirm the PCR results, revealing the absence or extremely low phytoplasma read counts, but a surprisingly high abundance of fastidious and xylem-limited fungus, Ceratobasidium sp. in CWBD-symptomatic plants. These findings cast doubt over the involvement of phytoplasma in CWBD and instead highlight the potential association of Ceratobasidium sp., strongly supporting the recent findings in mainland Southeast Asia. Further investigations are needed to verify the etiology of CWBD and identify infection mechanisms of Ceratobasidium sp. to develop effective diagnostic and control methods for disease management.

This study examines the importance of cupuassu, a tropical fruit native to the Amazon, to Brazil’s biodiversity, the Amazon biome, and its potential for economic development. Cupuassu is a Non-Timber Forest Product and a fruit of the Theobroma genus, which also includes cocoa. Just in the state of Pará alone, cupuassu production in 2019 was over 4100 t with a gross value of 2.6 million USD produced. However, cupuassu cultivation still needs investment through technological advances to overcome threats such as witches’ broom disease and mycotoxin contamination. Cupuassu fruit is composed of pulp, seeds, and a shell; all these parts have a chemical composition with numerous bioactive compounds, especially the seeds, which also contain stimulant compounds, besides lipids and proteins. The processing of the whole cupuassu fruit has its economic value in the commercialization of the pulp, the extraction of cupuassu butter, and a product called Cupulate^®. However, in this process, the cake resulting from the oil pressing, often considered a waste product, has potential as a source of proteins, peptides, lipids, and bioactive molecules with functional and nutritional properties. Recycling this fruit processing waste can create high-value-added products for various industries and promote a circular economy. Full article

Mixed production systems play a vital role in the economic sustainability and ecological balance of agroecosystems. Cocoa and plantain are key crops in Ecuador but face phytosanitary challenges, like witches’ broom and black sigatoka diseases, especially when cultivated under monocropping systems. Combining habitat manipulation with adaptive pathogen management (APM) strategies can mitigate these challenges, but their efficacy in mixed cropping systems remains unclear. This study investigates disease and pest incidence in mixed cocoa–plantain systems during the establishment phase, focusing on the impact of spatial arrangements. Mixed agroecosystems showed a lower witches’ broom incidence in cocoa than monocultures. Whereas, in plantain, there was a consistent black sigatoka incidence across spatial arrangements but a lower infection rate per leaf within mixed systems. We found varied nematode populations with monocultures hosting the highest root damage due to phytoparasitic nematodes. Weevil populations were also influenced by spatial arrangements with monocultures among the highest. Overall, mixed agroecosystems influence disease and pest incidence, potentially hindering pathogen spread. Plantain–cocoa associations reduce disease incidence in cocoa but may not affect the overall incidence of black sigatoka in plantain, at least during the establishment phase. Continued monitoring is crucial for understanding the long-term impacts and microclimatic effects on pest populations that could offer sustainable pest management strategies, reducing the reliance on chemical pesticides.

Background: Eyelid dermatitis is a common, multifactorial, chronic, and/or relapsing condition with a considerable impact on life quality that represents a diagnostic and treatment challenge. Methods: We carried out a single-blind, controlled, randomized, parallel-group study to evaluate the efficacy of two dermo-cosmetics (cream for the eyelids and eye contour area and cleansing face cream) in which the key ingredient was witch hazel extract, compared to generic cream, in the treatment of patients affected by eyelid dermatitis. Enrolled subjects were treated and followed-up for 4 weeks; dermatological evaluation was objectively performed using the DLQI, OSDI, NRS–itch, and EDSI indicators. Results: The products tested proved to be more effective than the placebo in ameliorating the dermatitis in the treated patients, based on all considered dermatological scores. In the treatment arm, we observed a reduction in both DLQI score and in the indicators related to the extension of dermatitis, greater than that observed in the control arm. Conclusions: This comparative study demonstrates the role of dermo-cosmetic products tested not only as a support treatment, but also as a first-choice clinical approach. Full article

Tamarisk witches’ broom, yellowing, and little leaf symptoms were observed during 2018–2023 surveys of rural deserts in central regions of Iran with the highest disease incidence up to 72% in Chah Afzal (Yazd province). A verification of the presence and identity of phytoplasmas associated with these symptoms was then performed. Tamarisk tree branch cuttings obtained from symptomatic plants sprouted up to 90.3% but with 15–25 days’ delay compared to the asymptomatic ones and showed internode shortening and witches’ broom, while the branch cuttings from asymptomatic plants had normal growth and sprouted up to 97.8%. Phytoplasma transmission by dodder bridges to periwinkle did not succeed, while nested polymerase chain reaction on the phytoplasma ribosomal gene followed by RFLP and phylogenetic analyses revealed the presence of ‘Candidatus Phytoplasma asteris’, ‘Ca. P. australasiae=australasiaticum’, and ‘Ca. P. trifolii’ (ribosomal subgroups 16SrI-B, 16SrII-D, and 16SrVI-A, respectively) in the samples from symptomatic plants only. Further amplifications were performed on selected phytoplasma-positive samples on tuf and secA genes, and the produced sequences indicated the presence of mixed phytoplasma infection in some of the samples. In particular, in the tuf gene, a mixed infection of ‘Ca. P. australasiae=australasiaticum’ and ‘Ca. P. trifolii’ was detected, while in the secA gene, the presence of ‘Ca. P. asteris’ or ‘Ca. P. tritici’ strains was identified. The first-time detection of diverse phytoplasma strains in symptomatic T. aphylla suggests that this species represent a relevant source of infection for the agricultural crops and for landscape plants especially when temperature allows insect vector transmission, and therefore, it represents a risk in every environment especially in the frame of climatic changes.
