Background and Aim: Understanding the developmental conditions of Cephalopina titillator larvae and their effect on the success of pupation and adult emergence can help prevent and control this disease in camels. Incubating C. titillator larvae in vitro requires optimized conditions that have not been adequately reported in the literature. This study aimed to optimize conditions for harvesting adult flies from third-stage larvae (L3). Materials and Methods: L3 collected from naturally infested camels was washed in sterile saline, weighed, and placed in vials containing local sand. The vials were covered with gauze and incubated at 30°C–36°C with 60%–62% relative humidity in an environmental chamber. Results: A minimum critical weight of 754 mg per larva was found to be essential for the successful eclosion of the adults, regardless of the sex of the emerged flies. The pupariation period lasted 1–8 days (d) and took 5–13 days. Most incubated L3 formed puparia, but most failed to emerge as adults. The success rate of eclosion was 37.1%. The hatched adults survived for up to 18 days, and the females survived longer (12 d; 6–18) than the males (8.1 d; 3–16). Conclusion: The higher eclosion success tendency of certain sand types might be influenced by the sand’s physical and/ or chemical characteristics. The current in vitro conditions resemble those during the hot seasons and are suitable for harvesting viable adults of C. titillator from L3.

Jordan has been one of the leading Arab countries in establishing academic programs in the field of speech-language pathology (SLP) in the Arab region. The first master's program was established at the University of Jordan in 1992 in Amman. The first bachelor's program in SLP was established in 1992 at the private Applied Sciences University in Amman, Jordan. Currently, there are two master's and four bachelor's programs in Jordan. The total number of graduates holding bachelor's degrees from the four programs is 2472, and the total number of graduates with master's degrees is 500. According to the records of the Licensing Unit at the Ministry of Health, there are 142 licensed speech-language pathologists, 754 technician speech-language pathologists, 27 licensed audiologists, 244 technician-audiologists, and seven assistant technician audiologists. The total number of ASHA-certified Jordanian SLPs is around 15. The profession of SLP in Jordan has progressed remarkably in the past twenty years; however, it requires more attention at different levels to continue to advance. More financial support is needed for scholars to conduct more rigorous research. A code of ethics should be developed to promote the service delivery models and SLP services. Additionally, more centers are needed all over the country to service the vast numbers of individuals with communication disorders. A professional association should be established immediately to regulate and promote the profession at all levels.

AbstractThe contemporary business landscape is witnessing a paradigm shift towards environmental sustainability, prompting organizations to adopt green practices. Among these, Green Employee Empowerment (GEE) and Green Training (GT) have emerged as pivotal strategies. This study aims to explore the interplay between GEE, GT, Job Satisfaction, Pro-environmental Behavior (PEB), and Environmental Performance (EP) within hotel organizations. Using a cross-sectional design, a questionnaire survey was administered to 400 full-time employees. The data were analyzed using Partial Least Square- Structural equation modelling (PLS-SEM) v4 techniques. The study’s findings highlight the substantial impact of GEE and GT on both PEB and Job Satisfaction among employees in hotel organizations. Interestingly, the results reveal that GEE significantly influences Environmental Performance (EP), underscoring its role in driving positive outcomes in terms of sustainability practices within hotels. However, the surprising finding is that GT, despite its emphasis on environmental training, has an insignificant impact on EP. This unexpected result warrants further exploration and underscores the need for a nuanced understanding of the effectiveness of different green initiatives in influencing the overall environmental performance. As hotels worldwide grapple with the imperative to adopt sustainable business practices, this study provides valuable insights and a roadmap for hotel organizations seeking to navigate the complex landscape of environmental responsibility and social accountability. The findings provide practical guidance for luxury hotels striving to strike a balance between economic success and environmental stewardship, fostering a holistic approach to sustainability in the hotel industry.

Background and Aim: Ostrich (Struthio camelus) farming in the United Arab Emirates (UAE) is a relatively new field of farming. Farmed ostriches are susceptible to ectoparasite infestation, which affects their production. This study was conducted to estimate the prevalence of ectoparasites on ostriches raised on a farm in Abu Dhabi Emirate. Materials and Methods: The feathers of 42 ostriches (26 females and 16 males) were collected and morphologically examined for ectoparasites. In total, 283 lice (89 males and 194 females) were collected from birds. However, there were no ticks or other ectoparasites. Lice were preserved in 1.5 mL tubes containing 70% ethanol and were later identified using taxonomic keys. The prevalence, mean intensity of infection, and mean abundance were estimated. Results: One louse species, Struthiolipeurus struthionis was identified. To the best of our knowledge, this is the first report of S. struthionis in ostriches raised in the UAE with an overall prevalence of 88%. The prevalence of lice was significantly higher in July (100%) than that in May (66.7%). Likewise, the mean intensity and abundance of lice were significantly higher in June (10.6 and 9.94, respectively) than in May (3.25 and 2.2, respectively). Conclusion: The high prevalence of lice poses a serious risk to ostrich farming by negatively affecting the health and productivity of ostriches.

Abstract Background End-stage renal disease (ESRD) is a growing cause of morbidity worldwide. Protein malnutrition is common among patients with ESRD. Peritoneal dialysis (PD) offers greater lifestyle flexibility and independence compared to the widely used treatments for ESRD. This study aimed to assess the nutritional status and the quality of life (QOL) of Palestinian patients undergoing PD, as well as the variables affecting these two outcomes. Methods A cross-sectional study was conducted on patients receiving PD at An-Najah National University Hospital, Palestine. The malnutrition-inflammation scale (MIS) was used to measure malnutrition, and the QOL score was evaluated using the Dutch WHOQOL-OLD module. Univariate and multivariate linear regressions were performed to check the association between the QOL and MIS scores. Results The study included 74 patients who were undergoing PD, with an average age of 50.5 ± 16.38. The majority of the patients were females. The study found a significant correlation between malnutrition and lower quality of life (QOL) scores, as measured by the WHOQOL-OLD questionnaire (p

A new species of parasitoid wasp (Braconidae, Microgastrinae) from the kingdom of Saudi Arabia (KSA) is described, Microplitis idreesae sp. nov. The genus is reported for the first time in the Eastern province of the KSA. This is the first host-parasitoid association for Microplitis documented in the country. The new species attacks Mythimna Ochsenheimer (Lepidoptera, Noctuidae). Natural history information is provided such as the association of males with females, geographical location, possible food plants, and details of wasp cocoons. In addition, a fragment of the mitochondrial cytochrome b gene is presented. A taxonomic key to the species of Microplitis reported from the KSA is provided. Characters of this new species and its affinities with the three previous species described from the KSA and four of the closely related to Palaeartic species are also discussed.

The venom derived from various sources of snakes represents a vast collection of predominantly protein-based toxins that exhibit a wide range of biological actions, including but not limited to inflammation, pain, cytotoxicity, cardiotoxicity, and neurotoxicity. The venom of a particular snake species is composed of several toxins, while the venoms of around 600 venomous snake species collectively encompass a substantial reservoir of pharmacologically intriguing compounds. Despite extensive research efforts, a significant portion of snake venoms remains uncharacterized. Recent findings have demonstrated the potential application of neurotoxins derived from snake venom in selectively targeting voltage-gated potassium channels (Kv). These neurotoxins include BPTI-Kunitz polypeptides, PLA2 neurotoxins, CRISPs, SVSPs, and various others. This study provides a comprehensive analysis of the existing literature on the significance of Kv channels in various tissues, highlighting their crucial role as proteins susceptible to modulation by diverse snake venoms. These toxins have demonstrated potential as valuable pharmacological resources and research tools for investigating the structural and functional characteristics of Kv channels.

Abstract Background The Middle East Respiratory Syndrome coronavirus (MERS‐CoV) is still listed on the WHO Research and Development Blueprint of emerging pathogens. Dromedary camels remain the only known animal reservoir of the virus. The animal‐to‐animal as well as the animal‐to‐human transmission in the MERS‐CoV cycles were reported. However, many aspects of these transmission chains are not well studied. One of these directions is the potential roles of various species of arthropods in the transmission of the virus. Objectives The main goal of the current work was to study the roles of several species of arthropods in the transmission of MERS‐CoV. Methodology To achieve this goal, we identified some MERS‐CoV naturally infected dromedary camel populations. We conducted a longitudinal study among these animals for more than 2 months. This was done by repeated testing of nasal swabs biweekly from some selected animals in this population for the presence of MERS‐CoV‐RNAs by real‐time PCR. During the duration of this study, we collected several species of arthropods (Culicoides, Stomoxys, Musca domestica and some Culex species) that shared the habitat and were circulating in this farm during this longitudinal study. Results Our results showing, despite the detection of the viral RNAs in some animals throughout this study, none of the examined species of arthropods tested positive for the viral RNA. Conclusions These results are suggesting that at least the tested species of arthropods may not play roles in the transmission of MERS‐CoV. However, more large‐scale studies are required to explore any potential roles of arthropods in the transmission cycle of MERS‐CoV.

This project is a rehearsal in language and its capacity to refuse comprehensibility. In this experimental process, we will be exploring the boundaries of legibility through a tracing of the shards and fragments embodied in the minor detail. With our sight fixed toward Palestine, we will explore how detail holds radical potential, be it in classical texts in the canon of Palestinian literature, or in the oral testimonies that have emerged from Gaza over the past 6 months. The focus on illegibility and language that defies comprehension exists in the shadow of genocide, where language fails to capture the immensity of the moment. Broken and sharp, it turns inward into a sense closer to emotion than to logic. In that sense, this project is also a rehearsal in utilizing language as matter, as material, as tangible touch.

Veterinary inspection of fish caught at the western side of the Arabian Gulf off the shore of Saudi Arabia in 2017 revealed abnormal irregular zigzag black lines in the skins of 135 out of 1500 (prevalence = 9 %) whitecheek sharks (Carcharhinus dussumieri). These lesions have been noticed in the dorsal and ventral part of the head near the snout and around the eyes, as well as in the skin of the pectoral fins. The parasitological, pathological and ultramorphological aspects of the sampled fish were studied using a light microscope, as well as scanning and transmission electron microscopes. Trichosomoidid-type eggs identified as Huffmanela sp. were found in the superficial layer of the skin. The mature eggs containing larvae (n = 75) were ellipsoidal or spindle-shaped, smooth-shelled, amber-brown to dark brown or even black in colour. The width of the eggs ranged from 34 to 49μm with lengths ranging from 95 to 107μm. The polar plugs of the immature eggs were slightly protruding, whereas mature eggs had clearly protruding polar plugs. The width of the polar plugs ranged from 4.5 – 9.5μm. The shells of the eggs were smooth and there was a thin layer seen near the polar areas. The infected skin exhibited desquamated epithelium, with inflammatory cell aggregations and melanophores in the debris. The underlying musculatures of the skin were free from any eggs, but showed mild pathological changes, including congestion of blood vessels, haemorrhages and oedema. The prevalence of infection showed seasonality, peaking significantly in the spring (18.18 %), with comparable prevalence rates in winter and summer (9.43 % and 8.57 %, respectively). However, infections dropped significantly during the autumn months (3.75 %). It is believed that this is the first study reporting the presence of Huffmanela sp. in whitecheek sharks at El-Jubail Province, Saudi Arabia, Arabian Gulf.

This study aimed at identifying the use of the social media network (Facebook) and its relationship to psychological compatibility of special education teachers by answering four questions that include all the variables of the current study. The study used the descriptive approach and developed a scale to reveal the relationship of Facebook use and psychological compatibility. The psychological scale was applied to a random sample of special education teachers (n=520), who constitute 18% from the study population in Aseer region. The results of the study showed that the period that special education teachers spend using Facebook that received the highest frequency was less than two hours per day. The results revealed that the level of psychological compatibility among special education teachers, who use Facebook was high. There was a negative relationship between the period that special education teachers spend using Facebook and the level of psychological compatibility. The results also indicated that there were no statistically significant differences attributed to the effect of gender on the period of use of Facebook among special education teachers.

This research investigates employee empowerment’s role in the relationship between quality management practices (QMPs) and innovation performance at five-star hotels in Jordan. A total of 400 workers who work in five-star hotels in Jordan were given a questionnaire with 29 questions that measured QMPs, employee empowerment, and innovation performance. The obtained data were analyzed by PLS-SEM. The results show that quality policy (QP) has an insignificant influence on employee empowerment and innovation performance, while quality commitment (QC) and quality education and training (QET) have a positive and significant influence on employee empowerment and innovation performance. The results also reveal that employee empowerment has a positive influence on innovation performance. Finally, employee empowerment as a mediator variable was not working on the relationship between QP and innovation performance but showed a significant role as a partial mediator between QC and innovation performance as well as QET and innovation performance. Discussion, theoretical and managerial implications for future research, and limitations are presented.

(1) Background: Water is necessary for the preparation of some medicines found in pharmacies where the local water source does not meet the required purity. This study aimed to investigate the presence of coliform contamination in water used for drug reconstitution in community pharmacies in Jordan. (2) Methods: Two water samples from 50 randomly selected community pharmacies representing all Jordanian governorates were filtered and then cultured in plate count agars to determine total microbial count, and in m-Endo Agar Les and Eosin Methylene Blue (EMB) agar to cultivate Escherichia coli (E. coli). The presence of E. coli was further characterized with gram stains, biochemical tests, and Polymerase chain reaction (PCR). Antibiotic susceptibility of isolated E. coli was tested against a variety of standard antibiotics. (3) Results: Community pharmacies used droppers filled with water from coolers (62%), bottled water (20%), boiled tap water (16%) and tap water (2%). The majority of the sampled water contained coliform bacteria (88%), and E. coli was isolated from 26% of all samples. Statistical analysis showed no significant difference in the percentage of contaminated water samples based on its source location. Nonetheless, the results showed a tendency for higher proportions of contamination in droppers filled from boiled tap water (37.5%; SE: 17.1), followed by water from water coolers (25.8%; SE: 7.9), and then from bottled water (20%; SE: 12.7). All of the isolated E. coli were sensitive to gentamycin, ciprofloxacin and levofloxacin. The susceptibility of the isolates to ceftazidime, doxycycline, tetracycline, azithromycin and amoxicillin/clavulanic acid were 92%, 61%, 46%, 23% and 15%, respectively. (4) Conclusions: This study confirms the widespread presence of multidrug-resistant bacteria in water intended for reconstituting drugs in local pharmacies. These findings expose an alarming situation that needs special attention by the acting pharmacists and competent authorities. Higher levels of personal hygiene in the pharmacies coupled with regular inspection of water quality may reduce the risk of microbial contamination in compounded products, especially multidrug-resistant strains of E. coli and other index microorganisms.

Background: In this experimental study, we aimed to assess the acaricidal effects of Elettaria cardamomum L. essential oil (ECEO) against Hyalomma anatolicum tick in cattle from Saudi Arabia. Methods: Gas chromatography-mass spectrometry (GC-MS) was performed to identify the chemical composition of ECEO. The acaricidal, larvicidal, and repellent activity of ECEO against H. anatolicum was studied through the adult immersion test (AIT), the larval packet test (LPT), the vertical movement behavior of tick’s larvae technique, anti-acetylcholinesterase (AChE) activity, and oxidative enzyme activity. Results: By GC/MS, the most compounds were 1,8-cineole (34.3%), α-terpinyl acetate (23.3%), and α-pinene (17.7%), respectively. ECEO significantly (p < 0.001) increased the mortality rate as a dose-dependent response. After ECEO Treatment, number of eggs, egg weight, and hatchability significantly declined as a dose-dependent response. ECEO at concentrations of 5 µL/mL and above completely killed the larva. The LC50 and LC90 values for ECEO were 1.46 and 2.68 µL/mL, respectively. ECEO at concentrations of 10, 20, and 40 µL/mL showed 100% repellency activity up to 60, 120, and 360 min incubation, respectively. ECEO, especially at ½ LC50 and LC50, significantly inhibited GST and AChE activities of H. anatolicum larvae compared to the control group. Conclusions: We found promising adulticidal, larvicidal, and repellent effects of ECEO against H. anatolicum as a vector of theileriosis in Saudi Arabia. We also found that ECEO displayed these activities through inhibiting AChE and GST. Nevertheless, additional investigations are required to confirm the accurate mechanisms and the relevance of ECEO in practical application.

Apoptosis is an evolutionarily conserved and tightly regulated cell death pathway. Physiological cell death is important for maintaining homeostasis and optimal biological conditions by continuous elimination of undesired or superfluous cells. The BH3-only pro-apoptotic members are strong inducers of apoptosis. The pro-apoptotic BH3-only protein Noxa activates multiple death pathways by inhibiting the anti-apoptotic Bcl-2 family protein, Mcl-1, and other protein members leading to Bax and Bak activation and MOMP. On the other hand, Puma is induced by p53-dependent and p53-independent apoptotic stimuli in several cancer cell lines. Moreover, this protein is involved in several physiological and pathological processes, such as immunity, cancer, and neurodegenerative diseases. Future heat shock research could disclose the effect of hyperthermia on both Noxa and BH3-only proteins. This suggests post-transcriptional mechanisms controlling the translation of both Puma and Noxa mRNA in heat-shocked cells. This study was also the chance to recapitulate the different reactional mechanisms investigated for caspases.

The purpose of this research was to examine the mediating effect of empowerment on the linkage between Total Quality Management (TQM) and service recovery performance in the hotel industry. Although much has been written about TQM, empowerment and service recovery performance, but the role of empowerment as a mediator in the relationship between TQM and service recovery performance has remained a relatively unexplored research area. A 93-item questionnaire is designed to measure TQM, empowerment and service recovery amongst employees in five-star hotels in Jordan, and 254 usable questionnaires were used in this study. Principal components analysis determined the factor structure and regression analysis determined the relationships between the study’s variables. The results revealed that the TQM implementations have positive effects on empowerment and service recovery performance. Moreover, the study found the full mediating effect of empowerment in the relationship between TQM and service recovery performance. Implications, limitations and future research are discussed at the end. This study proposes model of influence of TQM in service recovery performance, whereby empowerment fully mediates this relationship.

Vertebrates are hosts to numerous parasites, belonging to many different taxa. These parasites differ in transmission, being through either direct contact, a faecal-oral route, ingestion of particular food items, vertical or sexual transmission, or by a vector. Assessing the impact of diet on parasitism can be difficult because analysis of faecal and stomach content are uncertain and labourious; and as with molecular methods, do not provide diet information over a longer period of time. We here explored whether the analysis of stable isotopes in hair provides insight into the impact of diet and the presence of parasites in the rodent Myodes glareolus. Twenty-one animals were examined for parasites and their hair analysed for stable isotopes (C and N). A positive correlation between δ15N and one species of intestinal parasite was observed in females. Furthermore, several ectoparasites were negatively correlated with δ15N, indicating that infections are further associated with foraging habits (size and layout of the home range, length and timing of foraging, interaction with other rodents, etc.) that set the rodents in direct contact with infected hosts. Although a limited number of animals were included, it seemed that the isotope values allowed for identification of the association between diet and parasite occurrence in this rodent. We therefore propose that this method is useful in providing further insight into host biology, feeding preferences and potential exposure to parasites species, contributing to the understanding of the complex relationship between hosts and parasites.

This paper draws on the perceptions of middle managers in Jordan to identify what determines upper management’s decision in International Hotel Chains (IHC) to invest in out-of-country training (OCT). A model employing the presence of relationships between ‘attitudes’, ‘benefits and usefulness’, ‘barriers’ and ‘IHC’s decision’ to invest in OCT, was proposed and examined. A total of 261 middle managers from IHCs in Jordan provided responses to a structured survey. Confirmatory factor analysis validated the dimensions for each construct. Structural equation modelling (SEM) was used to test the relationships among the four constructs of the study. The results showed a direct relationship between attitudes and benefits/usefulness to IHC’s decision to invest in OCT, and demonstrated the mediating role of attitudes in the inverse r

Setaria tundra is a mosquito-borne filarial nematode of cervids in Europe. It has recently been associated with an emerging epidemic disease causing severe morbidity and mortality in reindeer and moose in Finland. Here, we present the first report of S. tundra in six roe deer (Capreolus capreolus) collected between October 2010 and March 2014 in Denmark. The deer originated from various localities across the country: the eastern part of the Jutland peninsular and four locations on the island Zealand. With the exception of one deer, with parasites residing in a transparent cyst just under the liver capsule, worms (ranging from 2 to >20/deer) were found free in the peritoneal cavity. The worms were identified as S. tundra by morphological examination and/or molecular typing of the mitochondrial 12S rRNA and cox1 genes, which showed 99.1–99.8% identity to previously published S. tundra isolates from Europe. Roe deer are generally considered as asymptomatic carriers and their numbers in Denmark have increased significantly in recent decades. In light of climatic changes which result in warmer, more humid weather in Scandinavia greater numbers of mosquitoes and, especially, improved conditions for development of parasite larvae in the mosquito vectors are expected, which may lead to increasing prevalence of S. tundra. Monitoring of this vector-borne parasite may thus be needed in order to enhance the knowledge of factors promoting its expansion and prevalence as well as predicting disease outbreaks.

Echinococcus multilocularis is an endemic parasite of red foxes in several European countries. This parasite has been present for decades in central Europe i.e. Switzerland, Eastern France, Southern Germany and Austria, which constitute the core endemic area of Europe. In the Scandinavian countries Sweden and Denmark, several recent findings were made in foxes. To better understand the dynamics and geographic spread of E. multilocularis in Europe, genetic studies have been undertaken using the DNA microsatellite marker EmsB. In Europe, the parasite spread in hitherto non-endemic areas was suspected to take place after founder events, in which the core endemic area presents a wider genetic diversity in comparison to newly endemic areas. However, identical parasite profiles can be shared between them, highlighting the parasite spreading in a mainland-island system. In this study, Swedish (27 adult worms from seven red foxes) and Danish (38 adult worms from nine red foxes) isolates were examined using fragment size analyses of the tandemly repeated microsatellite EmsB in order to compare the genetic profiles of the Scandinavian worms with a reference collection of European worm isolates from seven countries. Six EmsB profiles were detected in the Scandinavian panel. Three profiles were described in Denmark and four in Sweden. Only one of these profiles was detected in both countries. All profiles identified in the present study have previously been found in other European countries, suggesting an epidemiological link. Due to the relatively low number of Scandinavian E. multilocularis isolates analysed so far, firm conclusions cannot be made regarding the true genetic diversity. Nevertheless, the low genetic variation detected in Sweden and Denmark in this study is similar to the values obtained from peripheral areas of the main European endemic focus, which were more recently colonized by E. multilocularis; and continuous surveillance of this parasite is warranted to provide further insight into its epidemiology in Scandinavia.

Toxins from marine animals provide molecular tools for the study of many ion channels, including mammalian voltage-gated potassium channels of the Kv1 family. Selectivity profiling and molecular investigation of these toxins have contributed to the development of novel drug leads with therapeutic potential for the treatment of ion channel-related diseases or channelopathies. Here, we review specific peptide and small-molecule marine toxins modulating Kv1 channels and thus cover recent findings of bioactives found in the venoms of marine Gastropod (cone snails), Cnidarian (sea anemones), and small compounds from cyanobacteria. Furthermore, we discuss pivotal advancements at exploiting the interaction of κM-conotoxin RIIIJ and heteromeric Kv1.1/1.2 channels as prevalent neuronal Kv complex. RIIIJ’s exquisite Kv1 subtype selectivity underpins a novel and facile functional classification of large-diameter dorsal root ganglion neurons. The vast potential of marine toxins warrants further collaborative efforts and high-throughput approaches aimed at the discovery and profiling of Kv1-targeted bioactives, which will greatly accelerate the development of a thorough molecular toolbox and much-needed therapeutics.
