Exposure of Caralluma tuberculata to biogenic selenium nanoparticles as in vitro rooting agent: Stimulates morpho-physiological and antioxidant defense system.

The commercial-scale production of Caralluma tuberculata faces significant challenges due to lower seed viability and sluggish rate of root growth in natural conditions. To overcome these obstacles, using phyto-mediated selenium nanomaterials as an in vitro rooting agent in plant in vitro cultures is a promising approach to facilitate rapid propagation and enhance the production of valuable therapeutic compounds. This study aimed to investigate the impact of phytosynthesized selenium nanoparticles (SeNPs) on the morphological growth attributes, physiological status, and secondary metabolite fabrication in in vitro propagated Caralluma tuberculata. The results demonstrated that a lower dose of SeNPs (100 µg/L) along with plant growth regulators (IBA 1 mg/L) had an affirmative effect on growth parameters and promoted earliest root initiation (4.6±0.98 days), highest rooting frequency (68.21±5.12%), number of roots (6.3±1.8), maximum fresh weight (710±6.01 mg) and dry weight (549.89±6.77 mg). However, higher levels of SeNPs (200 and 400 µg/L) in the growth media proved detrimental to growth and development. Further, stress caused by SeNPs at 100 µg/L along with PGRs (IBA 1 mg/L) produced a higher level of total chlorophyll contents (32.66± 4.36 µg/ml), while cultures exposed to 200 µg/L SeNPs alone exhibited the maximum amount of proline contents (10.5± 1.32 µg/ml). Interestingly, exposure to 400 µg/L SeNPs induced a stress response in the cultures, leading to increased levels of total phenolic content (3.4 ± 0.052), total flavonoid content (1.8 ± 0.034), and antioxidant activity 82 ± 4.8%). Furthermore, the combination of 100 µg/L SeNPs and plant growth regulators (1 mg/L IBA) led to accelerated enzymatic antioxidant activities, including superoxide dismutase (SOD = 4.4 ± 0.067 U/mg), peroxidase dismutase (POD = 3.3 ± 0.043 U/mg), catalase (CAT = 2.8 ± 0.048 U/mg), and ascorbate peroxidase (APx = 1.6 ± 0.082 U/mg). This is the first report that highlights the efficacy of SeNPs in culture media and presents a promising approach for the commercial propagation of C. tuberculata with a strong antioxidant defense system in vitro.

Treatment with onion bulb extract both prevents and reverses allergic inflammation in a murine model of asthma.

CONTEXT: Asthma presents a global health challenge. The main pharmacotherapy is synthetic chemicals and biological-based drugs that are costly, and have significant side effects. In contrast, use of natural products, such as onion (Allium cepa L., Amaryllidaceae) in the treatment of airway diseases has increased world-wide because of their perceived efficacy and little safety concerns. However, their pharmacological actions remain largely uncharacterized. OBJECTIVE: We investigated whether onion bulb extract (OBE) can (1) reverse established asthma phenotype (therapeutic treatment) and/or (2) prevent the development of the asthma phenotype, if given before the immunization process (preventative treatment). MATERIALS AND METHODS: Six groups of male Balb/c mice were established for the therapeutic (21 days) and five groups for the preventative (19 days) treatment protocols; including PBS and house dust mite (HDM)-challenged mice treated with vehicle or OBE (30, 60, and 100 mg/kg/i.p.). Airways inflammation was determined using cytology, histology, immunofluorescence, Western blot, and serum IgE. RESULTS: Therapeutic (60 mg/kg/i.p.) and preventative (100 mg/kg/i.p.) OBE treatment resulted in down-regulation of HDM-induced airway cellular influx, histopathological changes and the increase in expression of pro-inflammatory signaling pathway EGFR, ERK1/2, AKT, pro-inflammatory cytokines and serum IgE. DISCUSSION AND CONCLUSION: Our data show that OBE is an effective anti-inflammatory agent with both therapeutic and preventative anti-asthma effects. These findings imply that onion/OBE may be used as an adjunct therapeutic agent in established asthma and/or to prevent development of allergic asthma. However, further studies to identify the active constituents, and demonstrate proof-of-concept in humans are needed.

Night eating and its relationship with BMI, stress, sleep quality and duration of study among university students.

INTRODUCTION: Night eating is a very common dietary behaviour among university students. This study aims to investigate the relationship between night eating and BMI, stress, sleep quality and duration of study among university students. MATERIALS AND METHODS: A total of 385 university students including foundation and undergraduate students took part in this study. Self-administered online surveys were used to obtain sociodemographic data, and anthropometry measurements including weight and height, night eating during studying, duration of the study, opinion on eating and academic performance, sleep quality, level of depression, anxiety, and stress of the respondents. Questionnaires were validated and IBM SPSS Statistics Software version 26.0 was used to analyse categorical and continuous variables. RESULTS: The findings showed that there was an association between night eaters and coffee consumption with BMI (p<0.001) and sleep quality (p<0.05). However, there was no association (p>0.05) found between the types of food eaten during night studying and the mean duration of the study. The results showed drinking coffee had an association with depression, anxiety, and stress (p<0.05) among Malaysian university students. CONCLUSION: Coffee consumption was common among undergraduate students during studying. Awareness of the risk of overconsumption of caffeine intake should be implemented in the future. However, this study did not include all types of food choices and drinks. Thus, frequency of eating energy dense food during night studying among students should be conducted in the future.

Capsicum annuum Oleoresin Nanoemulgel - Design Characterization and In vitro Investigation of Anticancer and Antimicrobial Activities.

BACKGROUND: The use of naturally occurring bioactive materials is getting great attention owing to their safety and environmental properties. Oily compounds, known as oleoresins, are expected to provide an important source for the natural products industry aiming to develop novel treatments for skin conditions. In this work, Capsicum annuum oleoresin nanoemulgel formulations have been prepared and investigated for their antibacterial and anticancer properties. METHODOLOGY: Several C. annuum oleoresin nanoemulgel formulations were prepared by incorporating a Carbopol 940 gel in a self-nanoemulsifying nanoemulsion consisting of C. annuum, tween 80, and span 80. The systems were characterized for particle size, polydispersity index (PDI), zeta potential, and rheology. The in vitro antimicrobial and cytotoxic activities of the optimum formulation were evaluated. RESULTS: The selected formulation is composed of 40% tween, 10% span 80, and 40% C. annuum oleoresin. This formulation produced a stable nanoemulsion with a narrow PDI value of 0.179 ± 0.08 and a droplet size of 104.0 ± 2.6 nm. Results of the in vitro antimicrobial studies indicated high potency of the systems against methicillin-resistant Staphylococcus aureus (MRSA) (zone of inhibition of 29 ± 1.9 mm), E. coli (33 ± 0.9 mm), K. pneumonia (30 ± 1.4 mm), and C. albicans (21 ± 1.5 mm), as compared to the reference antibiotic, ampicillin (18 ± 1.4 mm against K. pneumonia), and antifungal agent, fluconazole (12 ± 0.1 mm against C. albicans). Furthermore, cytotoxicity results, expressed as IC50 values, revealed that the oleoresin and its nanoemulgel had the best effects against the HepG2 cell line (IC50 value of 79.43 µg/mL for the nanoemulgel) and MCF7 (IC50 value of 57.54 µg/mL), and the most potent effect was found against 3T3 (IC50 value of 45.7 µg/m- L). On the other side, the system did not substantially exhibit activity against By-61 and Hela. CONCLUSION: C. annuum oleoresin and its nanoemulgel can be considered valuable sources for the discovery of new antibacterial, antifungal, and anticancer compounds in the pharmaceutical industry, especially due to their potent activity against various cancer cell lines as well as bacterial and fungal strains.

Benign-by-design plant extract-mediated preparation of copper oxide nanoparticles for environmentally related applications.

A facile, cost-competitive, scalable and novel synthetic approach is used to prepare copper oxide (CuO) nanoparticles (NPs) using Betel leaf (Piper betle) extracts as reducing, capping, and stabilizing agents. CuO-NPs were characterized using various analytical techniques, including Fourier-transform infrared (FTIR) spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), as well as photoluminescence (PL) measurements. The activity of CuO-NPs was investigated towards Congo red dye degradation, supercapacitor energy storage and antibacterial activity. A maximum of 89% photodegradation of Congo red dye (CR) was obtained. The nanoparticle modified electrode also exhibited a specific capacitance (Csp) of 179 Fg-1. Furthermore, the antibacterial potential of CuO NPs was evaluated against Bacillus subtilis and Pseudomonas aeruginosa, both strains displaying high antibacterial performance.

Biosynthesis, characterization, magnetic hyperthermia, and in vitro toxicity evaluation of quercetin-loaded magnetoliposome lipid bilayer hybrid system on MCF-7 breast cancer.

Novel biocompatible and effective hyperthermia (HT) treatment materials for breast cancer therapeutic have recently attracting researchers, because of their effective ablation of cancer cells and negligible damage to healthy cells. Magnetoliposome (MLs) have numerous possibilities for utilize in cancer treatment, including smart drug delivery (SDD) mediated through alternating magnetic fields (AMF). In this work, magnesium ferrite (MgFe2O4) encapsulated with liposomes lipid bilayer (MLs), Quercetin (Q)-loaded MgFe2O4@Liposomes (Q-MLs) nano-hybrid system were successfully synthesized for magnetic hyperthermia (MHT) and SDD applications. The hybrid system was well-investigated by different techniques using X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Energy dispersive X-ray (EDX), Vibrating sample magnetometer (VSM), Transmission electron microscope (TEM), and Zeta Potential (ZP). The characterization results confirmed the improving quercetin-loading on the MLs surface. TEM analysis indicated the synthesized MgFe2O4, MLs, and Q-MLs were spherical with an average size of 23.7, 35.5, and 329.5 nm, respectively. The VSM results revealed that the MgFe2O4 exhibit excellent and effective saturation magnetization (MS) (40.5 emu/g). Quercetin drug loading and entrapment efficiency were found to be equal to 2.1 ± 0.1% and 42.3 ± 2.2%, respectively. The in-vitro Q release from Q-loaded MLs was found 40.2% at pH 5.1 and 69.87% at pH 7.4, verifying the Q-loading pH sensitivity. The MLs and Q-MLs hybrid system as MHT agents exhibit specific absorption rate (SAR) values of 197 and 205 W/g, correspondingly. Furthermore, the Q-MLs cytotoxicity was studied on the MCF-7 breast cancer cell line, and the obtained data demonstrated that the Q-MLs have a high cytotoxicity effect compared to MLs and free Q.

Assessment of anticancer, antimicrobial, antidiabetic, anti-obesity and antioxidant activity of Ocimum Basilicum seeds essential oil from Palestine.

BACKGROUND: Many modern pharmaceutical researchers continue to focus on the discovery and evaluation of natural compounds for possible therapies for obesity, diabetes, infections, cancer, and oxidative stress. Extraction of Ocimum basilicum seed essential oil and evaluation of its antioxidant, anti-obesity, antidiabetic, antibacterial, and cytotoxic activities were the goals of the current study. METHOD: O. basilicum seed essential oil was extracted and evaluated for its anticancer, antimicrobial, antioxidant, anti-obesity, and anti-diabetic properties utilizing standard biomedical assays. RESULTS: O. basilicum seed essential oil showed good anticancer activity against Hep3B (IC50 56.23 ± 1.32 µg/ml) and MCF-7 (80.35 ± 1.17 µg/ml) when compared with the positive control, Doxorubicin. In addition, the essential oil showed potent antibacterial (against Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Proteus mirabilis, and Pseudomonas aeruginosa) and antifungal (against Candida albicans) activities. Moreover, as for the anti-amylase test, IC50 was 74.13 ± 1.1 µg/ml, a potent effect compared with the IC50 of acarbose, which was 28.10 ± 0.7 µg/ml. On the other hand, for the anti-lipase test, the IC50 was 112.20 ± 0.7 µg/ml a moderate effect compared with the IC50 of orlistat, which was 12.30 ± 0.8 µg/ml. Finally, the oil had a potent antioxidant effect with an IC50 of 23.44 ± 0.9 µg/ml compared with trolox (IC50 was 2.7 ± 0.5 µg/ml). CONCLUSION: This study has provided initial data that supports the importance of O. basilcum essential oil in traditional medicine. The extracted oil not only exhibited significant anticancer, antimicrobial, and antioxidant properties but also antidiabetic and anti-obesity effects, which provided a foundation for future research.

Impact of vitamin D in children with chronic tonsillitis (immunohistochemical study of CD68 polarisation and proinflammatory cytokines estimation).

Inflammatory processes are increasingly attributed to macrophage polarization. Proinflammatory macrophages promote T helper (Th) 1 response, tissue repair, and Th2 responses. Detection of macrophages in tissue sections is facilitated by CD68. Our study is focused on the expression of CD68 and the estimation of proinflammatory cytokines in children's patients with chronic tonsillitis secondary to vitamin D supplementation. This hospital-based Randomized prospective case-control study was conducted on 80 children with chronic tonsillitis associated with vitamin D deficiency where (40 received vitamin D 50,000 IU weekly for 3-6 months and 40 received 5 ml distilled water as placebo). The serum 25-hydroxyvitamin D [25(OH)D] was measured using an Enzyme-linked immunosorbent assay on all included children. Different histological and immunohistochemical studies for the detection of CD68 were done. There was a significantly lower serum level of 25(OH)D in the placebo group versus the vitamin D group (P < 0.001). The levels of pro-inflammatory cytokines, TNFα, and IL-2 significantly increased in the placebo group as compared to the vitamin D group (P < 0.001). The increased level of IL-4 and IL-10 in the placebo group as compared to the vitamin D group was insignificant (P = 0.32, 0.82) respectively. Vitamin D supplementation alleviated the deleterious effect of chronic tonsillitis on the histological structure of the tonsil. Tonsillar tissues of the children in the control and vitamin D groups demonstrated a highly statistically significantly lower number of CD68 immunoexpressing cells compared with those in the placebo group (P < 0.001). Low vitamin D may play a role in chronic tonsillitis. Vitamin D supplementation could help reduce the occurrence of chronic tonsillitis in susceptible children.

Skin healing effects of an innovative polymer-based oil Nigella sativa: a rabbit model experimental study.

OBJECTIVE: Natural wound dressings composed of gelatin (GEL) and chitosan (CH) impregnated with bioactive compounds (Nigella sativa oil) were prepared and characterized to evaluate their potential application. MATERIALS AND METHODS: The formulated composite was subjected to γ-irradiation. In vitro, the ferric-reducing antioxidant power (FRAP) assay and antibiofilm activities were evaluated. In vivo, the tissue wound-healing process was studied by applying GEL-CH-Nigella in dorsal skin rabbit tissue. On days 7 and 14, the biochemical biomarker and histological analysis were determined. RESULTS: At 10 kGy, FRAP assays exhibited the highest antioxidant activity (380 mmol/kg). A significant inhibition of anti-biofilm activity was observed against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) (p<0.01). Fourteen days post-surgery, a significant reduction in thiobarbituric acid-reactive compounds (TBARs) was observed compared to the GEL-CH group. Concerning oxidative stress status, GEL-CH-Nigella significantly improved superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities. A histological analysis revealed that GEL-CH-Nigella accelerated wound closure and improved collagenisation and enhanced epidermal tissue thickness. CONCLUSIONS: These results indicate that GEL-CH-Nigella wound dressing is a promising biomaterial for engineered tissue.

Gender as a Moderator of Spirituality and Spiritual Care in ICU Nurses During COVID-19 Pandemic.

Background: Earlier research has found that female healthcare providers often report greater spirituality and spiritual care than males. This would evoke attention toward factors contributing to such differences, particularly gender. Aim: To examine the moderating effects of gender on the relationships between demographic characteristics of ICU nurses and their perceived spirituality and spiritual care. Methods: A cross-sectional correlational design was used to recruit a national sample of 865 nurses working in ICUs in Jordan and providing care to patients diagnosed with COVID-19. Data were collected using a self-report bilingual version of Spirituality and Spiritual Care Rating Scale (SSC) and analysed using the SPSS software package. Results: Social status, monthly income, and receiving previous courses or lecture training on spirituality and spiritual care were predictors of higher SSCRS scores. Working with COVID-19 patients was a positive predictor (B = 0.074, p = 0.023), suggesting that working with COVID-19 patients is more likely to have a higher level of SSC. Gender was a negative predictor (B = -0.066, p = 0.046), suggesting that female participants are likelier to have a lower SSC score. Conclusion: Working with patients during the COVID-19 pandemic positively impacted nurses' perception of SCC, but female nurses had lower score than male nurses indicating the need for more emphasis on training female nurses and exploring further the areas in which they need more training and to be able to provide an effective SSC. A sustainable up-to-date training and in-service education programs responding to nurses' needs and emerged emergencies crisis need to be integrated into nursing quality of care policy development.

Cathine and cathinone disposition kinetics and neurotransmitter profile in several organs of rats exposed to a single dose of Catha edulis (Vahl) Forssk. ex Endl. extract.

OBJECTIVES: Catha edulis (Vahl) Forssk. ex Endl. (Khat) is a stimulant plant that contains cathine and cathinone, which its abuses induce euphoria, alertness, and motor activity. Since the toxicokinetics of these substances remain unclear, this study was carried out to investigate the disposition kinetics of cathine and cathinone, the neurotransmitter profile, following a single dose of C. edulis extract in rats. METHODS: Twenty-four adult male Wistar albino rats (250-300 g) were randomly selected and divided into six groups of four rats each. All groups received a single oral dose of 2,000 mg/kg body weight, and blood and tissue samples from the brain, lung, heart, liver, and kidney were obtained at intervals of 0.5, 1, 2.5, 5, 12, and 24 h. The cathine and cathinone concentrations were identified and quantified using ion trap ultra-high performance liquid chromatography (HPLC-IT/MS). The neurotransmitter profile was detected using the quadrupole time of flight UPLC-QTOF/MS method. RESULTS: The lung, liver, and heart tissues attained the highest levels of cathine, while the highest level of cathinone was determined in the heart. Cathine and cathinone concentrations in the blood and heart peaked at 0.5 h. The concentrations peaked in the brain 2.5 h later, indicating that the heart had an immediate effect, whereas the brain had a longer-lasting one. They have longer half-lives (2.68 and 5.07 h, respectively) and may remain in the brain for longer durations (3.31 and 2.31 h, respectively). The neurotransmitters epinephrine, dopamine, norepinephrine, and serotonin were detected in a delayed, prolonged and organ-specific manner. CONCLUSIONS: Cathine and cathinone were deposited in considerable concentrations in all tissues analyzed, with the highest Cmax in the lung and Tmax in the heart tissues but not in the brain. In addition, neurotransmitters such as adrenaline, dopamine, norepinephrine, and serotonin were differentially detected in all tested samples in a organ-specific fashion. More study is needed to identify cathine and cathinone's effects on neurotransmitter profiles. Nevertheless, these findings provided a further basis for experimental, clinical, and forensic investigations.

Nephroprotective Effect of Diosmin against Cisplatin-Induced Kidney Damage by Modulating IL-1ß, IL-6, TNFα and Renal Oxidative Damage.

Cisplatin (CP) is a platinum compound of the alkylating agent class that is used for the treatment of various types of cancer. However, CP treatments in cancer patients are accountable for nephrotoxicity, as it is a major adverse effect. Hence, this research study was proposed to investigate the nephroprotective effect of diosmin, a flavonoid glycoside of hesperidin derivatives against cisplatin-induced kidney damage. Wistar rats received a single intraperitoneal (i.p) injection of CP (7.5 mg/kg, i.p) to induce nephrotoxicity. The administration of CP significantly (p < 0.001) increased the markers of kidney function test (creatinine, blood urea nitrogen, and uric acid) and demonstrated histopathological changes in the kidney of the CP-treated nephrotoxic group. In addition, the CP-treated nephrotoxic group demonstrated a significant (p < 0.001) increase in lipid peroxidation (LPO) levels and depleted activities of reduced glutathione (GSH), glutathione peroxidase (GPx), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT).However, diosmin (100 and 200 mg/kg) treatments significantly reduced the elevated levels of kidney function test parameters and restored structural changes in the kidney (p < 0.001). The administration of diosmin (100 and 200 mg/kg) significantly (p < 0.001) reduced LPO levels, increased GSH content and showed improvements in the activities of GPx, GR, SOD and CAT. The markers of inflammatory cytokines such as IL-1ß, IL-6 and TNFα significantly (p < 0.001) increased in the CP-treated nephrotoxic group, whereas diosmin (100 and 200 mg/kg) treatments significantly (p < 0.001) reduced the elevated levels of these cytokines. The findings of this research demonstrate the nephroprotective effect of diosmin against CP-induced kidney damage. Therefore, we conclude that diosmin may be used as a supplement in the management of nephrotoxicity associated with CP treatments in cancer patients.

Comparing and contrasting different herbal products intended for the management of obesity approved in the Palestinian markets.

BACKGROUND: The use of conventional medical therapies has proven to have many setbacks and safety concerns that need further improvement. However, herbal medicine has been used for over 2000 years, and many studies have proven the use of herbs to be effective and safe. This article discussed the efficacy of different herbal products used in the management of obesity. To evaluate the efficacy of seven herbal-based weight loss products currently available on the Palestinian market, using in vitro assays to screen for antioxidants, anti-amylase, and anti-lipase effects for each product. METHOD: Pancreatic lipase and salivary amylase inhibitory activities, as well as antioxidant analysis, were tested in vitro on a variety of herbal products. Then the IC50 was measured for each test. RESULTS: The anti-lipase assay results, IC50 values in (µg/mL) of each of the seven products (Product A, product B, product C, product D, product E, product F, and product G) were 114.78, 532.1, 60.18, 53.33, 244.9, 38.9, and 48.97, respectively. The IC50 value for orlistat (Reference) was 12.3 µg/ml. On the other hand, the IC50 value for alpha amylase inhibition of the seven products (Product A, product B, product C, product D, product E, product F, and product F) were 345.93, 13,803.84 (Inactive), 73.79, 130.91, 165.95, 28.18, and 33.11 µg/ml respectively, while acarbose (Reference) was 23.38 µg/ml. The antioxidant activity (IC50 values) for the seven products (Product A, product B, product C, product D, product E, product F, and product F) were 1258.92, 707.94, 79.43, 186.20, 164.81, 17.53, and 10.47 µg/ml respectively. While the IC50 value for Trolox was 2.70 µg/ml. CONCLUSION: It can be concluded that the seven products showed varied anti-lipase, anti-amylase, and antioxidant effects. However, products F and G showed superiority in all categories.

Neonatal palliative care: Assessing the nurses educational needs for terminally ill patients.

BACKGROUND: For terminally sick neonates and their families, it's crucial to provide holistic nursing care that incorporates both curative and palliative care as much as feasible. It is well known that the biggest obstacle to delivering palliative care for neonatal children is a lack of training for nurses. Aim: The aim of this research is to investigate the experiences of nurses who provide care for neonates who are terminally ill as well as their educational requirements for neonatal palliative care. METHOD: A cross-sectional descriptive study was conducted among 200 nurses working in a tertiary center providing care for terminally ill neonates in Saudi Arabia. Data was collected from using Neonatal Palliative Care Questionnaire (QNPC) from January 2021 to March 2021. RESULTS: Two hundred nurses were surveyed (the response rate was 79%). The mean age of the 158 participants was 35.67 (standard deviation (SD): 7.43), and the majority were female (151; 95.6%). The majority were bachelor's holders (119; 75.3%), with more than 5 years of experience in providing care for neonates (100; 63.3%). Most of the participants reported not receiving any education about palliative care (115; 72.8%). Nurses reported a moderate level of experience in all areas of neonatal palliative care. The total mean score of palliative care experiences of neonates was 3.42 (SD: 1.35). However, the majority of nurses reported little experience discussing the transition period to palliative care for neonates 2.95 (SD: 1.93), the discussion of code status (DNR) during terminal illness of neonates 3.11 (SD: 1.54) and spiritual support 2.90 (SD: 1.55). CONCLUSION: The assessment of the fundamental skills of neonatal palliative care by nurses was insufficient. To enhance the quality of care, it is crucial to incorporate education on neonatal palliative care into programs for nursing staff development.

The rationale of applying inspiratory/expiratory muscle training within the same respiratory cycle in children with bronchial asthma: a placebo-controlled randomized clinical investigation.

OBJECTIVE: Even though positive implications of inspiratory muscle training (In-MT) have been established in children and adolescents with bronchial asthma (C/AwBA), the role of combined inspiratory and expiratory muscle training (Ex-MT) within the same respiratory cycle (In/Ex-SC) is still unknown. This study was, therefore, set out to explore the effect of In/Ex-SC on respiratory muscle strength, pulmonary functions, and control of asthma symptoms in C/AwBA. METHODS: This was a placebo-controlled randomized clinical investigation that included 51 C/AwBA (12-18 years). Participants were assigned randomly into three groups: Placebo, In-MT only, or combined In/Ex-SC training (n = 17, each group). The training was conducted for ∼35 min, thrice/week over 12 weeks. The maximal inspiratory (IPmax) and expiratory (EPmax) pressure (indicating the strength of the inspiratory and expiratory muscles, respectively), pulmonary functions [forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC index], and asthma control test (ACT) were assessed before and after the intervention. RESULTS: The In/Ex-SC yielded larger increases in IPmax and EPmax than either the Placebo training (P=.031 and P=.009 respectively) or the In-MT (P=.029 and P=.032 respectively). Further, In/Ex-SC produced favorable improvement in FEV1, FVC, and FEV1/FVC compared to the Placebo training (P=.001, P=.004, and P=.0005 respectively) or In-MT (P=.038, P=.037, and P=.025 respectively) training. Furthermore, In/Ex-SC led to better control of asthma symptoms than the Placebo (P<.001) or In-MT (P=.002) training. CONCLUSION: This study provides evidence that combined In/Ex-SC can considerably improve respiratory muscle strength, enhance pulmonary function, and promote control over asthma symptoms in C/AwBA.

Acute urinary retention in a 27-year-old male secondary to benign prostatic hyperplasia treated with Holmium Enucleation of the Prostate (HOLEP).

INTRODUCTION: Benign prostatic hyperplasia (BPH) is common in the ageing male. Clinical manifestations like retention impact on a patient's quality of life. Alterations in androgen activity at the androgen receptor complex level in the prostate contribute to prostatic hyperplasia with the highest incidence occurring in males in their 70's. There remains a paucity of cases in young males who develop acute urinary retention secondary to BPH. We present a case of a 27-year-old male who developed acute urinary retention secondary to BPH who required a Holmium Laser Enucleation of his Prostate (HOLEP). CASE DESCRIPTION: A 27 year old man was admitted in acute urinary retention. BPH was diagnosed via way of radiological imaging and histological assessment. After pre-operative sperm banking and suprapubic catheterisation, the patient underwent a HOLEP. He had biochemically confirmed hypogonadotrophic hypogonadism which was at odds with his muscular, physical appearance. Total testosterone levels had fluctuated following admission suggesting an exogenous substance was interfering with the hypothalamic-pituitary-gonadal axis but he denied exogenous steroid use. RESULT: The patient successfully passed his voiding trial on the second post-operative day and remained catheter free. Post-operative uroflowmetry and sexual function remain unknown as patient disengaged with follow up. CONCLUSION: HOLEP prostatectomy is a safe and effective way of managing BPH in younger patients following sperm banking and assessment by endocrinology.

Preclinical study of vitamin D deficiency in the pathogenesis of metabolic syndrome in rats.

OBJECTIVE: To explore the impact of vitamin D deficiency (VD-) in the pathogenesis of metabolic syndrome (MetS). MATERIALS AND METHODS: Models of (VD-) and (MetS) were induced in male Wister rats by dividing into four groups, group-I for the development of (VD-) by intraperitoneal injection of paricalcitol for 3 weeks, group II for (MetS) model by adding 10% fructose to their drinking water for 8 weeks, the group III for induction of combined (VD- + MetS) and group-IV as a control. Ultimately, the parameters of (VD-) and (MetS) were assessed at zero time and after 8 weeks. RESULTS: Both (VD-) and (MetS) groups alone displayed a remarkable enhancement of blood pressure, glucose and insulin levels, triglycerides, cholesterol, and low-density lipoproteins with a reduction of high-density lipoproteins. Additionally, all distinguishing features of obesity were substantially increased. Nevertheless, the combined group (VD-+MetS) demonstrated an expeditious and substantial increase in all the aforesaid parameters compared to the (VD-) and (MetS) groups alone. CONCLUSIONS: The hallmark of this study, reinforces a new frontier of awareness of the deleterious effect of (VD-) on each component of (MetS). Eventually, supplementation of vitamin D can circumvent the elements of (MetS) and needs further validation by determination of (VD-) molecular pathway on the parameters of (MetS).

Phytochemical Analysis and Antioxidant, Antibacterial, and Antifungal Effects of Essential Oil of Black Caraway (Nigella sativa L.) Seeds against Drug-Resistant Clinically Pathogenic Microorganisms.

Nigella sativa (NS) is a plant that has long been utilized in traditional medicine as a treatment for certain diseases. The aim of this work was to valorize the essential oil (EO) of this species by phytochemical analysis and antimicrobial and antioxidant evaluation. EO was extracted by hydrodistillation from the seeds of Nigella sativa (EO-NS). Phytochemical content of EO-NS was evaluated by use of gas chromatography coupled to mass spectrometry (GC-MS/MS). Antioxidant ability was in vitro determined by use of three assays: 2.2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing power (FRAP), and total antioxidant capacity (TAC) relative to two synthetic antioxidants: BHT and quercetin. Antimicrobial effect was evaluated against four clinically important bacterial strains (Staphylococcus aureus, ATCC 6633; Escherichia coli, K12; Bacillus subtilis, DSM 6333; and Proteus mirabilis, ATCC 29906) and against four fungal strains (Candida albicans, ATCC 10231; Aspergillus niger, MTCC 282; Aspergillus flavus, MTCC 9606; and Fusarium oxysporum, MTCC 9913). Fifteen constituents that accounted for the majority of the mass of the EO-NS were identified and quantified by use of GC-MSMS. The main component was O-cymene (37.82%), followed by carvacrol (17.68%), α-pinene (10.09%), trans-sabinene hydrate (9.90%), and 4-terpineol (7.15%). EO-NS exhibited significant antioxidant activity with IC50, EC50, and total antioxidant capacity (TAC) of 0.017 ± 0.0002, 0.1196 ± 0.012, and 114.059 ± 0.97 mg EAA/g, respectively. Additionally, EO-NS exhibited promising antibacterial activity on all strains under investigation, especially on E. coli K12 resulting in inhibition diameter of 38.67 ± 0.58 mm and a minimum inhibitory concentration (MIC) of 1.34 ± 0.00 µg/mL. Also, EO-NS had significant antifungal efficacy, with a percentage of inhibition of 67.45 ± 2.31% and MIC of 2.69 ± 0.00 µg/mL against F. oxysporum, MTCC 9913 and with a diameter of inhibition 42 ± 0.00 mm and MIC of 0.67 ± 0.00 µg/mL against C. albicans. To minimize development of antibiotic-resistant bacteria, EO-NS can be utilized as a natural, alternative to synthetic antibiotics and antioxidants to treat free radicals implicated in microbial infection-related inflammatory reactions.

Response of Rhizobacterial strains and organic amendments on chickpea growth.

Plant Growth Promoting Rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and promote plant growth through a variety of mechanisms such as phosphate solubilization, phytohormones production, antifungal activity and also improve plant growth and yield. Field experiment was carried out to investigate the residual effect of organic amendments plus soil microbes along with integrated nutrient management. (PGPR) are important soil organism that promotes plant growth and yield root colonization is an example of a direct and indirect mechanism. The treatments included control, (inorganic fertilizer and no organic fertilization).Five bacterial strains were identified morphologically and biochemically screened from the rhizospheres of chickpea, lentil, barseem, mungbean, and sesame. The experiment was conducted at the Arid Zone Research Center in D.I.Khan (Pakistan). The majority of isolates resulted in significant increase in shoot length, root length, and dry matter production of Cicer arietinum seedlings' shoot and root. The experiment represented that isolates treated plots with rhizobium strain inoculation resulted in greater plant height (35.000 cm) and nodule count (38.00) No of pods per plant-1 (44.66) when compared to the control treatment, While (Mesorhizobium cicero) along with organic amendments showed significant response the greater root length (50 cm) was observed in T4 treatment. The Performance of rhizobial strains on chickpea germination in an arid environment was found to significantly increase crop germination percentage. This combination thus increases nitrogen and phosphorus uptake in inoculation treated plots. The study found that plots with inoculation treatments yielded significantly higher than non-treated plots Treatment with Mesorhizobium Cicero and compost resulted in a higher grain yield (8%) as compared to the control. The greater grain yield was observed in Treatment T4 (183.67).The result showed that use of PGPR have the potential to increase nutrient absorption from soil while improved growth of chickpea.

A comprehensive analysis of clinical, quality of life, and cost-effectiveness outcomes of key treatment options for benign prostatic hyperplasia.

Treatment options for men with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) have variable efficacy, safety, and retreatment profiles, contributing to variations in patient quality of life and healthcare costs. This study examined the long-term cost-effectiveness of generic combination therapy (CT), prostatic urethral lift (PUL), water vapor thermal therapy (WVTT), photoselective vaporization of the prostate (PVP), and transurethral resection of the prostate (TURP) for the treatment of BPH. A systematic literature review was performed to identify clinical trials of CT, PUL, WVTT, PVP, and TURP that reported change in International Prostate Symptom Score (IPSS) for men with BPH and a prostate volume ≤80 cm3. A random-effects network meta-analysis was used to account for the differences in patient baseline clinical characteristics between trials. An Excel-based Markov model was developed with a cohort of males with a mean age of 63 and an average IPSS of 22 to assess the cost-effectiveness of these treatment options at 1 and 5 years from a US Medicare perspective. Procedural and adverse event (AE)-related costs were based on 2021 Medicare reimbursement rates. Total Medicare costs at 5 years were highest for PUL ($9,580), followed by generic CT ($8,223), TURP ($6,328), PVP ($6,152), and WVTT ($2,655). The total cost of PUL was driven by procedural ($7,258) and retreatment ($1,168) costs. At 5 years, CT and PUL were associated with fewer quality-adjusted life years (QALYs) than WVTT, PVP, and TURP. Compared to WVTT, the incremental cost-effectiveness ratios (ICERs) for both TURP and PVP were above a willingness-to-pay threshold of $50,000/QALY (TURP: $64,409/QALY; PVP: $87,483/QALY). This study provides long-term cost-effectiveness evidence for several common treatment options for men with BPH. WVTT is an effective and economically viable treatment in resource-constrained environments.
