RESUMEN
Ghee production form one of the largest segments of the milk consumption and utilization pattern in India. Recently, cow ghee has become more popular and fetching premium over buffalo ghee as there are innumerable health benefits credit to cow ghee since they contain an important array of nutrients and therapeutic principles. Therefore, the present investigation was conducted to differentiate and characterize cow ghee from buffalo ghee using physico-chemical parameters viz. BR reading, RM value, Polenske value, Kirschner value and different color values. Pure cow and buffalo ghee samples were prepared using creamery butter method. Pure ghee samples (cow and buffalo) and cow ghee samples admixed with buffalo ghee @ 5%, 10%, 15% and 20% were analyzed for above mentioned physico-chemical parameters and different color parameters. The results revealed that BR reading, RM value, Polenske value and Kirschner value of pure cow ghee ranged from 41.87-43.62, 27.5-31.13, 1.30-1.90 and 20.74-24.14 and in buffalo ghee these values ranged from 40.01-43.23, 31.91-39.99, 1.10-1.50 and 26.84-33.96, respectively. The color values i.e. lightness (L), redness(a), yellowness (b), yellowness index (Y) and whiteness index (W) of pure cow ghee ranged from 70.17-81.56, - 14.04 to - 28.96, 59.68-79.31, 74.25-88.92 and 16.07-28.85 and of buffalo ghee ranged from 71.89-83.71, - 1.07 to - 11.92, 1.39-9.61, 5.21-22.46 and 68.74-84.61. BR reading, RM value, Polenske value and L, a, b and Y of cow ghee adulterated with buffalo ghee up to 20% falls within the range of different pure cow ghee samples but whiteness index (W) and Kirschner value of admixed cow ghee (23.91 and 34.86) were having significantly higher values than the pure cow ghee (21.07 and 25.45, respectively). Kirschner Value and whiteness index (W) can be used to distinguish cow ghee from buffalo ghee.
RESUMEN
The main aim of this study was to deliver green tea catechins with enhanced bioavailability using niosomal system. Catechins-loaded niosomes were prepared using food grade surfactant, Tween 60 and membrane stabilizers namely, lauryl alcohol, cetyl alcohol and cholesterol by thin film hydration technique. Catechins-loaded niosomes exhibited a hydrodynamic diameter of 58.48 nm with a narrow size distribution (PDI = 0.13) and zeta potential of - 31.75 mV, suggestive for homogeneity and good stability. Niosomes entrapped about 85.82% of catechin and showed sustained release under simulated GI conditions. Morphology of niosomal vesicles were carried out using scanning electron microscopy-energy X-ray dispersion spectroscopy, transmission electron microscopy and atomic force microscopy. Fourier-transform infrared spectroscopy and High-performance liquid chromatography analysis confirmed successful encapsulation of catechins. Antioxidant activity of catechins was retained in the niosomal form. Fortification of milk with catechins loaded niosomes showed no significant changes on sensory, physicochemical properties and exhibited higher antioxidant property.
RESUMEN
The use of virtual reality (VR) and mixed reality (MR) technology in clinical psychology is growing. Efficacious VR-based treatments for a variety of disorders have been developed. However, the field of technology-assisted psychotherapy is constantly changing with the advancement in technology. Factors such as interdisciplinary collaboration, consumer familiarity and adoption of VR products, and progress in clinical science all need to be taken into consideration when integrating virtual technologies into psychotherapies. We aim to present an overview of current expert opinions on the use of virtual technologies in the treatment of anxiety and stress-related disorders. An anonymous survey was distributed to a select group of researchers and clinicians, using an analytic framework known as Strengths, Weaknesses, Opportunities, and Threats (SWOT). Overall, the respondents had an optimistic outlook regarding the current use as well as future development and implementation of technology-assisted interventions. VR and MR psychotherapies offer distinct advantages that can overcome shortcomings associated with traditional therapy. The respondents acknowledged and discussed current limitations of VR and MR psychotherapies. They recommended consolidation of existing knowledge and encouraged standardisation in both theory and practice. Continued research is needed to leverage the strengths of VR and MR to develop better treatments.Abbreviations: AR: Augmented Reality; MR: Mixed Reality; RCT: Randomised Controlled Trial; SWOT: Strengths, Weaknesses, Opportunities, and Threats; VR: Virtual Reality; VR-EBT: Virtual Reality Exposure-Based Therapy.

Evidence of self-help interventions for adjustment disorder (AjD) is limited. This study aims at testing in a randomized controlled trial (RCT) the effectiveness of a disorder-specific, Internet-delivered cognitive-behavioural therapy (ICBT) intervention for AjD. Participants were randomly allocated to either an ICBT with brief weekly telephone support (n = 34) or a waiting list group (n = 34). Beck's inventories for depression and anxiety were used as primary outcomes. The secondary outcomes were AjD symptoms, post-traumatic growth, positive and negative affect, and quality of life. In all, 76.5% of the participants completed the intervention. Compared with the control group, participants in the intervention condition showed significantly greater improvement in all outcomes (Cohen's d ranged from 0.54 to 1.21) except in anxiety symptoms measured by Beck Anxiety Inventory (d = 0.27). Only ICBT group showed a significant improvement in post-traumatic growth, positive and negative affect, and quality of life. The number of cases that achieved clinically meaningful change in all outcome measures was also higher in the ICBT group. All therapeutic gains were maintained at 3-, 6- and 12-month follow-ups. The current study provides evidence on the effectiveness of ICBT interventions to reduce the impact of AjD. Results suggest that brief self-help intervention with minimal therapist support is more effective than the mere passage of time in reducing the distress symptoms associated to the disorder and also can confer additional benefits.

BACKGROUND: The Positive and Negative Affect Schedule (PANAS) is the most widely and frequently used scale to assess positive and negative affect. The PANAS has been validated in several languages, and it has shown excellent psychometric properties in the general population and some clinical samples, such as forensic samples, substance users, and adult women with fibromyalgia. Nevertheless, the psychometric properties of the scale have not yet been examined in clinical samples with anxiety, depressive, and adjustment disorders. In addition, the proliferation of Internet-based treatments has led to the development of a wide range of assessments conducted online with digital versions of pen and paper self-report questionnaires. However, no validations have been carried out to analyze the psychometric properties of the online version of the PANAS. The present study investigates the psychometric properties of the online Spanish version of the PANAS in a clinical sample of individuals with emotional disorders. METHODS: The sample was composed of 595 Spanish adult volunteers with a diagnosis of depressive disorder (n = 237), anxiety disorder (n = 284), or adjustment disorder (n = 74). Factor structure, construct validity, internal consistency, and sensitivity to change were analyzed. RESULTS: Confirmatory factor analysis yielded a latent structure of two independent factors, consistent with previous validations of the instrument. The analyses showed adequate convergent and discriminant validity, good internal consistency as well as sensitivity to change. CONCLUSIONS: Overall, the results obtained in this study show that the online version of the PANAS has adequate psychometric properties for the assessment of positive and negative affect in a Spanish clinical population.

BACKGROUND: Internet-based treatments appear to be a promising way to enhance the in vivo exposure approach, specifically in terms of acceptability and access to treatment. However, the literature on specific phobias is scarce, and, as far as we know, there are no studies on Flying Phobia (FP). This study aims to investigate the effectiveness of an Internet-based exposure treatment for FP (NO-FEAR Airlines) that includes exposure scenarios composed of images and sounds, versus a waiting-list control group. A secondary aim is to explore two ways of delivering NO-FEAR Airlines, with and without therapist guidance. METHODS: A randomized controlled trial (RCT) was conducted in which 69 participants were allocated to: 1) NO-FEAR Airlines totally self-applied, 2) NO-FEAR Airlines with therapist guidance, 3) a waiting-list control group. Primary outcome measures were the Fear of Flying Questionnaire-II and the Fear of Flying Scale. Secondary outcomes included the Fear and Avoidance Scales, Clinician Severity Scale, and Patient's Improvement scale. Behavioral outcomes (post-treatment flights and safety behaviors) were also included. Mixed-model analyses with no ad hoc imputations were conducted for primary and secondary outcome measures. RESULTS: NO-FEAR Airlines (with and without therapist guidance) was significantly effective, compared to the waiting list control group, on all primary and secondary outcomes (all ps < .05), and no significant differences were found between the two ways of delivering the intervention. Significant improvements on diagnostic status and reliable change indexes were also found in both treatment groups at post-treatment. Regarding behavioral outcomes, significant differences in safety behaviors were found at post-treatment, compared to the waiting list. Treatment gains were maintained at 3- and 12-month follow-ups. CONCLUSION: FP can be treated effectively via the Internet. NO-FEAR Airlines helps to enhance the exposure technique and provide access to evidence-based psychological treatment to more people in need. These data are congruent with previous studies highlighting the usefulness of computer-assisted exposure programs for FP, and they contribute to the literature on Internet-based interventions. To the best of our knowledge, this is the first RCT to investigate the effectiveness of an Internet-based treatment for FP and explore two ways of delivering the intervention (with and without therapist guidance).

BACKGROUND: More research is needed in the field of Internet-delivered Cognitive Behavioral Treatments (ICBTs) for specific phobia in order to understand which characteristics are important in online exposure scenarios. The aim of the present work was to conduct a feasibility pilot study to explore participants' opinions, preferences, and acceptability ratings of two types of images (still images vs 360° navigable images) in an ICBT for Flying Phobia (FP). A secondary aim was to test the potential effectiveness of the two active treatment arms compared to a waiting list control group. An exploratory aim was to compare the role of navigable images vs. still images in the level of sense of presence and reality judgment and explore their possible mediation in treatment effectiveness. METHODS: Participants were randomly allocated to three conditions: NO-FEAR Airlines with still images (n = 26), NO-FEAR Airlines with still and navigable images (n = 26), and a waiting list group (n = 26). Primary outcome measures were participants' opinions, preferences, satisfaction, and acceptance regarding the images used in the exposure scenarios. Secondary outcome measures included FP symptomatology outcomes and measures of sense of presence and reality judgment. RESULTS: Participants in the study preferred navigable images over still images before and after treatment (over 84%), and they considered them more effective and logical for the treatment of their problem. However, adherence in the experimental conditions was low (42.3% dropout rate), and more participants withdrew from the group that included navigable images compared to the group that only included still images (14 vs. 8), with no statistical differences in attrition between the two conditions. NO-FEAR Airlines proved to be effective in reducing FP symptomatology compared to the control group, with large between-group effect sizes on all FP measures (ranging from 0.76 to 2.79). No significant mediation effect was found for sense of presence or reality judgment in treatment effectiveness. DISCUSSION: The results of the current study suggest that participants prefer more immersive images in exposure scenarios, providing data that can help to design useful exposure scenarios to treat specific phobias in the future. They also provide evidence supporting the effectiveness of an ICBT for FP. TRIAL REGISTRATION: Registered at Clinicaltrials.gov (NCT03900559) on April 9, 2019. Retrospectively registered.
RESUMEN
Internet- and mobile-based interventions (IMIs) are being developed for a wide range of psychological disorders and they showed their effectiveness in multiple studies. Specific phobia (SP) is one of the most common anxiety disorders, and research about IMIs for their treatment has also been conducted in recent years. The aim of this paper was to conduct a systematic review and preliminary meta-analysis exploring IMIs for the treatment of SP. A comprehensive search conducted in five different databases identified 9 studies (4 pre-post studies, 5 randomized controlled trials) with 7 Internet-based interventions and 2 mobile-based interventions. Results showed that exposure was the main component of all interventions, and that animal phobia was the most common subtype. Samples included children, adolescents, and adults. A preliminary meta-analysis of the included studies showed that participants receiving IMIs experienced a significant reduction of SP symptoms from pre- to post-treatment (g = 1.15). This systematic review found that there is already some evidence in the literature supporting the potential benefits of IMIs for SP. However, the number of studies included is small and more research should be carried out in the field.
RESUMEN
The aim of this study was to develop a niosomal system to deliver milk bioactive peptides with potential for enhanced bioavailability. Milk casein was hydrolyzed with Flavourzyme, and the hydrolysates were ultrafiltered to obtain low-molecular-weight peptides with enhanced antioxidant activity. Biopeptide-loaded niosomes were prepared by a high shear homogenization method. Peptide-loaded niosomes exhibited a mean particle size of 37.64 ± 0.98 nm with narrow size distribution (PDI = 24.66 ± 0.008%) and high zeta potential (-23.36 mV). The niosomes encapsulated about 67% of peptides into the vesicles and showed controlled and sustained release under simulated gastrointestinal conditions as compared to free peptides. The antioxidant activity of the peptides was not affected due to their encapsulation into niosomes. Morphology of peptide-loaded niosomes was determined by scanning electron microscopy, transmission electron microscopy and atomic force microscopy, and the microstructural interactions analyzed by Fourier transform infrared clearly indicated the formation of peptide-loaded niosomes. High-performance liquid chromatography spectra of peptides in the niosomes and the free peptides were similar, thus confirming their entrapment into the niosomes.

BACKGROUND: Flying Phobia (FP) is a prevalent disorder that can cause serious interference in a person's life. ICBT interventions have already shown their efficacy in several studies, but studies in the field of specific phobias are still scarce. Moreover, few studies have investigated the feasibility of using different types of images in exposure scenarios in ICBTs and no studies have been carried out on the role of sense of presence and reality judgement. The aim of the present study is to explore the feasibility of an ICBT for FP (NO-FEAR Airlines) using two types of images with different levels of immersion (still and navigable images). A secondary aim is to explore the potential effectiveness of the two experimental conditions using two types of images compared to a waiting list control group. Finally, the role of navigable images compared to the still images in the level of anxiety, sense of presence, and reality judgement will also be explored. This paper presents the study protocol. METHODS: This study is a three-armed feasibility pilot study with the following conditions: NO-FEAR Airlines with navigable images, NO-FEAR Airlines with still images, and a waiting list group. A minimum of 60 participants will be recruited. The intervention will have a maximum duration of 6 weeks. Measurements will be taken at four different moments: baseline, post-intervention, and two follow-ups (3- and 12-month). Participants' opinions, preference, satisfaction and acceptance regarding the images used in the exposure scenarios will be assessed. FP symptomatology outcomes will also be considered for secondary analyses. The anxiety, sense of presence, and reality judgement in the exposure scenarios will also be analysed. DISCUSSION: This study will conduct a pilot study on the feasibility of an ICBT for FP and it is the first one to explore the evaluation of patients of the two type of images (still and navigable) and the role of presence and reality judgement in exposure scenarios delivered through the Internet. Research in this field can have an impact on the way these scenarios are designed and developed, as well as helping to explore whether they have any effect on adherence. TRIAL REGISTRATION: NCT03900559. Trial Registration date 3 April 2019, retrospectively registered.
RESUMEN
INTRODUCTION: Grief is an emotional reaction to the loss of a loved one with a natural recovery. Approximately 10% of people who lose a loved one develop prolonged grief disorder (PGD). Internet-based and computer-based interventions (ie, internet-delivered cognitive-behavioural therapy, iCBT) are a cost-effective alternative that makes it possible to reach more people with PGD. The main aim of this study is to assess the feasibility of a new iCBT-called GROw-for PGD. As a secondary objective, the potential effectiveness of GROw will be explored. METHODS AND ANALYSIS: This study is a two-arm feasibility randomised trial. A total of 48 adults with PGD who meet the eligibility criteria will be randomised to the experimental group (iCBT: GROw) or the active control group (face-to-face CBT treatment). The treatment is organised sequentially in eight modules in the iCBT format and 8-10 sessions in the face-to-face format, and both formats have the same therapeutic components. There will be five assessment points with qualitative and quantitative evaluations: screening, baseline, after the intervention, 3-month follow-up and 12-month follow-up. Consistent with the objectives, the measures are related to the feasibility outcomes for the main aim of the study (participant adherence, expectations and satisfaction with the treatment, preferences, alliance and utility) and psychological and mental health outcomes for secondary analyses (symptoms of grief, symptoms of depression, symptoms of anxiety, affectivity, quality of life, work and social adaptation, post-traumatic growth, purpose in life, mindfulness and compassion). ETHICS AND DISSEMINATION: The Ethics Committee of the Universitat Jaume I (Castellón, Spain) granted approval for the study (CD/002/2019). Dissemination will include publications and presentations at national and international conferences. TRIAL REGISTRATION NUMBER: NCT04462146.

BACKGROUND: Adjustment Disorders (AjD) are one of the most prevalent psychological problems in primary and hospital care. It is necessary to have evidence-based instruments to help professionals diagnose and better understand this problem, which has been little studied. This study presents an adaptation of the Inventory of Complicated Grief for the assessment of AjD symptoms, referred to as the Inventory of Stress and Loss (ISL), and explores the differences in the response to stressful situations between general and clinical Spanish populations. METHODS: The general sample included 208 participants, and the clinical sample 91 patients with AjD. RESULTS: Results showed that the ISL has high internal consistency. Confirmatory factor analysis showed one single factor, as in the original questionnaire. With respect to concurrent validity, the ISL correlated positively with the STAI-T. Finally, significant differences were found in the total score on the questionnaire between the clinical and general samples, and between men and women in the general sample. CONCLUSIONS: Results suggest that the ISL is a simple, useful assessment tool that exhibits good psychometric properties and makes it possible to differentiate normal reactions to a stressful situation from pathological reactions.

Adjustment disorder (AjD) is one of the most common disorders in clinical practice, and its symptoms are severe enough to cause great distress and functional impairment. The AjD CBT protocol specifically developed for this disorder has shown positive results when delivered face to face and through virtual reality. Despite existing evidence supporting the benefits of therapeutic homework as part of a psychological intervention, little is known about how to increase homework engagement in psychotherapy. This study examines the feasibility (doability, initial efficacy and acceptability) of a digital support system to deliver homework via the Internet in the treatment of AjD. Participants were randomly assigned to a traditional homework condition or a digital support system condition. Both interventions resulted in statistically significant improvements, with large effect sizes, in all the outcome measures at post-treatment, with no significant differences between groups. At 12-month follow-up, these therapeutic gains were maintained, and an improvement was even observed in both conditions, with no significant differences between groups. Additionally, treatment satisfaction predicted efficacy in both groups separately and when the whole group was considered. This is the first study to explore the feasibility an initial efficacy of delivering a therapeutic homework component for AjD through the Internet.

Antecedentes: los Trastornos Adaptativos (TA) son uno de los problemas psicológicos más prevalentes en atención primaria y hospitalaria. Necesitamos disponer de instrumentos basados en la evidencia que ayuden a los profesionales a diagnosticar y a atender mejor este problema tan poco estudiado. Este estudio presenta la adaptación del Inventario de Duelo Complicado para la evaluación de los síntomas del TA, denominado Inventario de Estrés y Pérdida (IEP), y explora las diferencias en la respuesta a situaciones estresantes entre la población general y clínica española. Métodos: la muestra general incluyó 208 participantes, y la muestra clínica 91 participantes con TA. Resultados: los resultados mostraron que el IEP tiene una alta consistencia interna. El análisis factorial confirmatorio mostró un único factor, como el cuestionario original. En cuanto a la validez convergente, el IEP correlacionó positivamente con el STAI-R. Finalmente, se encontraron diferencias significativas en la puntuación total del cuestionario entre la muestra general y clínica, y entre hombres y mujeres de la muestra general. Conclusiones: los resultados sugieren que el IEP es una herramienta de evaluación simple y útil que muestra buenos resultados psicométricos y hace posible diferenciar las reacciones normales ante un acontecimiento estresante de las patológicas
