RESUMO
The aim of this study was to evaluate the impact of salt stress on morphological, yield, biochemical, and molecular attributes of different barley genotypes. Ten genotypes were cultivated at Fayoum Research Station, El-Fayoum Governorate, Egypt, during two seasons (2020-2021 and 2021-2022), and they were exposed to two different salt concentrations (tap water as a control and 8000 ppm). The results showed that genotypes and salt stress had a significant impact on all morphological and physiological parameters. The morphological parameters (plant height) and yield attributes (spike length, number of grains per spike, and grain yield per plant) of all barley genotypes were significantly decreased under salt stress as compared to control plants. Under salt stress, the total soluble sugars, proline, total phenol, total flavonoid, ascorbic acid, malondialdehyde, hydrogen peroxide, and sodium contents of the shoots of all barley genotypes significantly increased while the potassium content decreased. L1, which is considered a sensitive genotype was more affected by salinity stress than the tolerance genotypes L4, L6, L9, and Giza 138. SDS-PAGE of seed proteins demonstrated high levels of genetic variety with a polymorphism rate of 42.11%. All genotypes evaluated revealed significant variations in the seed protein biochemical markers, with new protein bands appearing and other protein bands disappearing in the protein patterns of genotypes cultivated under various conditions. Two molecular marker techniques (SCoT and ISSR primers) were used in this study. Ten Start Codon Targeted (SCoT) primers exhibited a total of 94 fragments with sizes ranging from 1800 base pairs to 100 base pairs; 29 of them were monomorphic, and 65 bands, with a polymorphism of 62.18%, were polymorphic. These bands contained 21 unique bands (9 positive specific markers and 12 negative specific markers). A total of 54 amplified bands with molecular sizes ranging from 2200 to 200 bp were produced using seven Inter Simple Sequence Repeat (ISSR) primers; 31 of them were monomorphic bands and 23 polymorphic bands had a 40.9% polymorphism. The techniques identified molecular genetic markers associated with salt tolerance in barley crop and successfully marked each genotype with distinct bands. The ten genotypes were sorted into two main groups by the unweighted pair group method of arithmetic averages (UPGMA) cluster analysis based on molecular markers and data at a genetic similarity coefficient level of 0.71.

Internet and Communication Technologies (ICTs) can foster efficient communication and knowledge acquisition, but there are also tradeoffs in terms of risks to one's privacy. Previous research, including work with the privacy calculus framework, indicates that factors such as perceived risks and benefits of using ICTs, ICT trust, and general privacy concerns can influence individuals' digital privacy-related decisions. One pervasive psychological factor that may potentially alter such privacy-related behaviors is acute stress. Acute stress can promote risk-seeking behaviors and a tendency to prefer immediate rewards over delayed, greater value rewards. However, the effect of acute stress in the applied context of privacy decision making is relatively unknown. Participants (N = 143) in this study were randomly assigned to either an acute stress task (socially evaluated cold pressor task) or an active control task (lukewarm water alone). Results revealed that acute stress condition increased information disclosure, as indexed by accepting more online cookies, sharing one's location more frequently, and revealing greater willingness to self-disclose personal information. In addition, the impact of individuals' levels of perceived risk and benefits, trust, and privacy concern on privacy decision making was examined. However, none of these constructs consistently influenced privacy decisions over and above the effect of stress. Overall, our findings suggest that acute stress has robust, independent influence on privacy decision making.
RESUMO
For many years, we have faced the complications of viral hepatitis and alcohol-related liver diseases such as cirrhosis, decompensation, portal hypertension, and hepatocellular carcinoma (HCC). Recently, we have seen a dynamic change in the field of hepatology. With the significant achievements in eradicating the hepatitis C virus by direct-acting antiviral agents and the rising epidemic of obesity, diabetes mellitus, and metabolic syndrome, there is a paradigm shift in the leading cause of liver cirrhosis and cancer to nonalcoholic fatty liver disease (NAFLD). Current data highlight the rapidly rising incidence of NAFLD-related HCC worldwide and expose the unseen part of the iceberg. In this review, we aim to update knowledge about the pathogenesis of NAFLD-induced HCC, surveillance difficulties, and promising disease markers. Molecular biomarkers, for example, may become a promising cornerstone for risk-stratified surveillance, early detection, and treatment selection for NAFLD-related HCC. Physicians can offer personalized and tailor-made clinical decisions for this unique patient subgroup.
RESUMO
SARS-CoV-2 causes mostly mild cases. However, a considerable number of patients develop fatal acute respiratory distress syndrome due to the cytokine storm and imbalanced immune response. Several therapies depending on immunomodulation have been used, including glucocorticoids and IL-6 blockers. However, their efficacy is not perfect with all patients and patients with concomitant bacterial infections and sepsis. Accordingly, studies on different immunomodulators, including extracorporeal techniques, are crucial to save this category of patients. In this review, we overviewed the different immunomodulation techniques shortly, with a brief review of extracorporeal methods.

BACKGROUND: COVID- 19 vaccines have been released, giving a major hope of getting rid of the dark pandemic crisis. The availability of vaccines does not necessarily mean that the mass vaccination program is a success. We aimed to investigate COVID-19 vaccination knowledge level, acceptance rate, and perception state among Egyptians. METHODS: An analytical cross-sectional online survey was carried out utilizing a selfadministered adult questionnaire that assesses vaccination acceptance with related sociodemographic factors and perceptions based on health belief model perspectives. Predictors of vaccination acceptance were based on logistic regression analysis. RESULTS: We analyzed data for 957 participants, aged 18-78 years, 55.7% were females, and 66.9% were healthcare workers (HCWs). About one-fourth had a history of confirmed COVID-19 infection and 56.5% would accept to have one of the COVID-19 vaccines, where "Pfizer" was the preferable one (37.8%), while "AstraZeneca" was the most rejected vaccine (26.8%). The 1st vaccine dose was received by 273 (28.5%) of which 260 were intended to receive the 2nd dose. Vaccine efficacy, side effects, protection time, and administration route were essentially among the factors that may influence their decision to accept COVID-19 vaccines. About 83.1% had good knowledge about vaccination which was significantly higher with increased age, among graduates/professionals, governmental workers, HCWs in addition to those able to save/invest money, had a history of confirmed COVID-19 infection and intending to have COVID-19 vaccine. Perceptions that vaccination decreases the chance of getting COVID-19 or its complications (OR = 9.28; CI: 5.03-17.12), vaccination makes less worry about catching COVID-19 (OR = 6.76; CI: 3.88-11.76), and being afraid of getting COVID-19 (OR = 2.04; CI: 1.26-3.31) were strong significant predictors for vaccine acceptance. CONCLUSION: Vaccine campaigns should emphasize vaccine benefits and highlight the severity of infection while addressing barriers to vaccination in order to improve vaccine coverage among populations.

BACKGROUND: Mental health apps have shown promise in improving mental health symptoms, including depressive symptoms. However, limited research has been aimed at understanding how specific app features and designs can optimize the therapeutic benefits and adherence to such mental health apps. OBJECTIVE: The primary purpose of this study is to investigate the effect of avatar customization on depressive symptoms and adherence to use a novel cognitive behavioral therapy (CBT)-based mental health app. The secondary aim is to examine whether specific app features, including journaling, mood tracking, and reminders, affect the usability of the mental health app. METHODS: College students were recruited from a university study recruitment pool website and via flyer advertisements throughout campus. A total of 94 participants completed a randomized controlled trial in which they were randomized to either customization or no customization version of the app. Customization involved personalizing a virtual avatar and a travel vehicle to one's own preferences and use of one's name throughout the app. Participants completed a 14-day trial using a novel CBT-based mental health app called AirHeart. Self-report scores for depressive symptoms, anxiety, and stress were measured at baseline and after the intervention. Postintervention survey measures also included usability and avatar identification questionnaires. RESULTS: Of the 94 enrolled participants, 83 (88%) completed the intervention and postintervention assessments. AirHeart app use significantly reduced symptoms of depression (P=.006) from baseline to the end of the 2-week intervention period for all participants, regardless of the customization condition. However, no differences in depressive symptoms (P=.17) or adherence (P=.80) were observed between the customization (39/83, 47%) and no customization (44/83, 53%) conditions. The frequency of journaling, usefulness of mood tracking, and helpfulness of reminders were not associated with changes in depressive symptoms or adherence (P>.05). Exploratory analyses showed that there were 3 moderate positive correlations between avatar identification and depressive symptoms (identification: r=-0.312, P=.02; connection: r=-0.305, P=.02; and lack of relatability: r=0.338, P=.01). CONCLUSIONS: These results indicate that CBT mental health apps, such as AirHeart, have the potential to reduce depressive symptoms over a short intervention period. The randomized controlled trial results demonstrated that customization of app features, such as avatars, does not further reduce depressive symptoms over and above the CBT modules and standard app features, including journal, reminders, and mood tracking. However, further research elucidating the relationship between virtual avatar identification and mental health systems is needed as society becomes increasingly more digitized. These findings have potential implications for improving the optimization of mental health app designs. TRIAL REGISTRATION: Open Science Framework t28gm; https://osf.io/t28gm.
RESUMO
Infantile hemangiomas (IHs) are common vascular tumors. In most cases, a benign course with favorable outcome can be anticipated. IH typically present as cutaneous lesions either with a localized or diffuse segmental distribution. Segmental hemangiomas in the face may be associated with brain and cardiac anomalies (PHACES syndrome), whereas airway involvement has been reported to be associated with hemangiomas in the "beard" area. Multiple cutaneous hemangiomas may be associated with visceral hemangiomas (commonly in the liver). In this report, we present a new association where deep paravertebral hemangiomatous lesions were observed to be associated with cutaneous back hemangiomas in two consecutive cases.
RESUMO
The aim of this study was to compare efficacy and safety of different combination regimens in re-treatment of HCV in the setting of inaccessibility of resistance testing. This real-life prospective study included 86 chronic HCV infected patients who experienced failure of treatment treated at Faculty of Medicine Ain shams Research Institute (MASRI) since 2018. 64% of the patients were males, with median age 50.2 years. They were re-treated using 1 of 3 proposed regimens of DAA combinations. One group received PAR/OMB/SOF/RBV for 12 weeks, another group received SOF/DAC/SIM/RBV for 12 weeks and a third received SOF/DAC/RBV for 24 weeks. Response to different regimens was assessed by comparing sustained virologic response (SVR) of each. Monitoring the occurrence of adverse events was performed. SVR was achieved in all but 3 patients (96.5% SVR), one in the SOF/DAC/SIM/RBV group and two in the SOF/DAC/RBV group. The group receiving RBV had more anaemia and hyperbilirubinemia. The first treatment regimen used was a significant predictor to SVR achievement. This study presents alternative treatment regimens for re-treatment of HCV patients in areas with limited resources in the case of non-availability of other regimens as velpatasvir, voxilaprevir, grazoprevir, elbasvir.
