RESUMO

BACKGROUND: One of the current challenges is to secure wheat crop production to meet the increasing global food demand and to face the increase in its purchasing power. Therefore, the current study aimed to exploit a new synthesized nanocomposite to enhance wheat growth under both normal and drought regime. The effectiveness of this nanocomposite in improving the microbiological quality of irrigation water and inhibiting the snail's growth was also assessed. RESULTS: Upon the employed one-step synthesis process, a spherical Fe/Cu/P nanocomposite was obtained with a mean particle size of 4.35 ± 1.524 nm. Cu2+, Fe2+, and P4+ were detected in the dried nanocomposite at 14.533 ± 0.176, 5.200 ± 0.208, and 34.167 ± 0.203 mg/ml concentration, respectively. This nanocomposite was found to exert antibacterial activity against Escherichia coli and Salmonella typhi. It caused good inhibition percent against Fusarium oxysporum (43.5 ± 1.47%) and reduced both its germination rate and germination efficiency. The lethal concentration 50 (LC50) of this nanocomposite against Lanistes carinatus snails was 76 ppm. The treated snails showed disturbance in their feeding habit and reached the prevention state. Significant histological changes were observed in snail digestive tract and male and female gonads. Drought stress on wheat's growth was mitigated in response to 100 and 300 ppm treatments. An increase in all assessed growth parameters was reported, mainly in the case of 100 ppm treatment under both standard and drought regimes. Compared to control plants, this stimulative effect was accompanied by a 2.12-fold rise in mitotic index and a 3.2-fold increase in total chromosomal abnormalities. CONCLUSION: The finding of the current study could be employed to mitigate the effect of drought stress on wheat growth and to enhance the microbiological quality of irrigation water. This is due to the increased efficacy of the newly synthesized Fe/Cu/P nanocomposite against bacteria, fungi, and snails. This methodology exhibits potential for promoting sustainable wheat growth and water resource conservation.

RESUMO

PURPOSE: This study aimed to evaluate the effect of adding platelet-rich plasma (PRP) during FGM to close medium-sized TM perforations. METHODS: This prospective randomized case-control study was conducted from February 2017 to March 2022. We included 320 patients with a medium-sized TM perforation with inactive mucosal otitis media. Transcanal FGM managed all patients under general or local anesthesia according to the patient preference. According to PRP, patients were divided into two groups: the first with PRP (170 patients) and the other without PRP (150 patients). We evaluated the closure rate of both groups one month, six months, and one year after the surgery. Also, we assessed the audiological performance before and one year after the operation for the patients with a successful closure. RESULTS: The closure rate was 87.6 % in the first group and 72.7 % in the second group, with a statistically significant difference between both groups as the P-value, was 0.001. Successful closure of the ABG to <10 dB occurred in 95.3 % of group A and 90.8 % of group B without a statistically significant difference between both groups (P-value = 0.163). CONCLUSIONS: This prospective comparative study on a relatively large number of patients revealed that FGM effectively closed medium-sized TM perforations. It also significantly improved postoperative audiological performance in both groups. Adding PRP during the FGM enhanced the closure success and the healing process without recorded complications. We recommend using the PRP in the routine FGM for closing medium-sized TM perforations.

RESUMO

INTRODUCTION: Burn injuries are underappreciated injuries that cause significant morbidity and mortality. Burn injuries, especially severe burns, trigger immunological and inflammatory responses, metabolic abnormalities, and distributive shock, all of which can be extended to multiple organ failures. Aloe vera (A. vera) has been exploited for its medicinal properties for centuries. The goal of the present study is to examine the therapeutic effect of topical and oral administration of A. vera against deep second-degree burn in rats. MATERIALS AND METHODS: skin burn was created on the back of rats, and wound healing was assessed within the three examined groups; control, topical A. vera and oral A. vera throughout 30 days. Wound tissues were examined histologically, immunohistochemically for the expression of transforming growth factor beta-1 (TGF-ß1), peroxiredoxin (Prdx6), and mRNA abundance of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) was assessed. RESULTS: Our finding showed acceleration of wound contraction with both topical and oral A. vera administration. Maturation of granulation tissues was seen in both A. vera-supplemented groups. The topical application of A. vera revealed marked remodelling of the granulation tissues and higher expression levels of TGF-ß1, VEGF, bFGF, and Prdx6 in comparison with control and oral A. vera groups (P < 0.001). CONCLUSION: Both oral and topical applications of A. vera have beneficial effects in deep second-degree burn wound healing by boosting the growth factors and antioxidant status of skin tissue. The topical treatment was more efficient in accelerating wound healing and hence could be used efficiently to treat second-degree burns.

RESUMO

Plantar warts continue to represent a therapeutic challenge due to treatment resistance and high recurrence rates. Intralesional methotrexate, a cytotoxic chemotherapeutic agent with in-vitro anti-viral properties has been used for many dermatological indications. Two previous studies evaluated intralesional injection of diluted methotrexate (in 0.5, 1, and 2 mg/ml dilutions) in the treatment of warts and found it poorly effective. The concentrations used in these studies were much lower than those used for other indications. The current, open-label, prospective, pilot study aimed to evaluate the safety and efficacy of the intralesional injection of full concentration (25 mg/ml) methotrexate in the treatment of plantar warts. Twenty patients with plantar warts, 10 (50%) males, and 10 (50%) females, with mean ± SD age of 28.45 ± 8.66 years (range, 18-46 years) received biweekly sessions of intralesional methotrexate (25 mg/ml) until complete clearance or for a maximum of 6 sessions. Complete clearance of warts was achieved in 2 (10%), 6 (30%), and 7 (35%) patients after 4, 5, and 6 sessions, respectively. Another 8 (40%) patients showed partial improvement after 6 sessions. The response rate did not correlate significantly with the number of warts. Nine (45%) patients did not report any side effects. Pain and bruises were reported by 8 (40%) and 6 (30%) patients, respectively. These findings suggest that biweekly sessions of full (25 mg/ml) concentration of methotrexate are a safe and effective treatment for plantar warts. It may be considered an alternative line of treatment for resistant cases.

RESUMO

BACKGROUND AND AIM: Bioprosthetic surgical aortic valve replacement (SAVR) is increasingly adopted in younger patients. We aimed to analyze mid-term follow-up data after SAVR to assess the performance of the prosthesis. METHODS: Data were collected from a single-center series of 154 patients, who underwent SAVR with a bioprosthetic heart valve with the RESILIA tissue at our Heart Centre in Siegburg. All procedural and midterm patient outcomes were documented. RESULTS: Patients had a mean age of 56.8 ± 9.9 years, 35.7% were female, and the mean logistic European system for cardiac operative risk evaluation (EuroSCORE) was 3.4 ± 3.6%. Diabetes (12.3%), atrial fibrillation (10.4%), and chronic obstructive pulmonary disease (COPD) (5.8%) were common comorbidities. The mean surgery duration was 163.8 ± 73.4 min, with the 23 mm (34.4%) and 25 mm (33.8%) heart valves being most frequently implanted. At 3-year follow-up, mean pressure gradient was 13.9 ± 5.9 mmHg, peak gradient was 23.6 ± 7.7 mmHg, and effective orifice area (EOA) was 1.9 ± 0.4 cm². No patient died during the operation, 3 (2.1%) patients within 30 days, and 4 (2.7%) thereafter with an overall mortality of n = 7. Of the surviving patients, 97.8% were in New York Heart Association (NYHA) class I/II and none had structural valve deterioration (SVD). CONCLUSION: Results of our single-center study indicate favorable procedural outcomes. The safety outcomes confirm preliminary earlier results of this novel bioprosthesis but include more patients and a longer midterm follow-up.

RESUMO

The urease enzyme has been an important target for the discovery of effective pharmacological and agricultural products. Thirteen regio-selectively alkylated benzimidazole-2-thione derivatives have been designed to carry the essential features of urease inhibitors. The urease enzyme was isolated from Helicobacter pylori as a recombinant urease utilizing the His-tag method. The isolated enzyme was purified and characterized using chromatographic and FPLC techniques showing a maximal activity of 200 mg/mL. Additionally, the commercial Jack bean urease was purchased and included in this study for comparative and mechanistic investigations. The designed compounds were synthesized and screened for their inhibitory activity against the two ureases. Compound 2 inhibited H. pylori and Jack bean ureases with IC50 values of 0.11; and 0.26 mM; respectively. While compound 5 showed IC50 values of 0.01; and 0.29 mM; respectively. Compounds 2 and 5 were docked against Helicobacter pylori urease (PDB ID: 1E9Y; resolution: 3.00 Å) and exhibited correct binding modes with free energy (ΔG) values of -9.74 and -13.82 kcal mol-1; respectively. Further; the in silico ADMET and toxicity properties of 2 and 5 indicated their general safeties and likeness to be used as drugs. Finally, the compounds' safety was authenticated by an in vitro cytotoxicity assay against fibroblast cells.

RESUMO

Introduction: The morbidly adherent placenta (MAP) is usually associated with maternal morbidity and mortality. The objective of this study was to evaluate the uterine cavity after uterine preservation surgeries for MAP. Material and methods: The study group comprised women ≥ 28 weeks pregnant with confirmed MAP, with a desire for future fertility, and who agreed to uterine preservation surgery for MAP. The uterine preservation surgeries done for MAP include the following: uterine artery ligation, placental-myometrial en bloc excision, and/or internal iliac artery (IIA) ligation. Participants managed by uterine preservation surgeries for MAP were evaluated 3-6 months after the surgeries using office hysteroscopies to evaluate the uterine cavity after uterine preservation surgeries (primary outcome). The secondary outcome measures the pregnancy outcome after uterine preservation surgery. Results: The hysteroscopic examination of the uterine cavity after uterine preservation surgery for MAP showed normal uterine cavity in 36 participants (90%), while it showed abnormal uterine cavity in 4 participants (10%). The abnormal hysteroscopic findings were a single abnormal hysteroscopic finding (endometrial polyp) in 2 participants (5%) and 2 abnormal hysteroscopic findings (incompletely healed scar with unilateral tubal ostial occlusion) in 2 participants (5%). The incidence of pregnancy after uterine preservation surgeries for MAP was 7.5% (3/40). Conclusions: The uterine preservation surgeries for MAP in this study had no effect on menstrual pattern, uterine cavity, or future fertility. The effect of uterine preservation surgeries for MAP on menstrual pattern, uterine cavity, and future fertility should be evaluated in future larger studies.

RESUMO

Rusts are a group of major diseases that have an adverse effect on crop production. Those targeting wheat are found in three principal forms: leaf, stripe, and stem rust. Leaf rust causes foliar disease in wheat; in Egypt, this causes a significant annual yield loss. The deployment of resistant genotypes has proved to be a relatively economical and environmentally sustainable method of controlling the disease. Gene pyramiding can be performed using traditional breeding techniques. Additionally, pathotypes can be introduced to examine specific leaf rust genes, or the breeder may conduct more complex breeding methods. Indirect selection via DNA markers linked to resistance genes may facilitate the transfer of targeted genes, either individually or in combination, even in a disease-free environment. The use of selective crosses to counter virulent races of leaf, stripe, and stem rust has resulted in the transfer of several resistance genes into new wheat germplasm from cultivated or wild species. Quantitative trait locus (QTL) technology has been adopted in a wide variety of novel approaches and is becoming increasingly recognized in wheat breeding. Moreover, several researchers have reported the transference of leaf and stripe rust resistance genes into susceptible wheat cultivars.

RESUMO

Recently, low level laser therapy was evaluated as an effective stimulating hair growth. Hair loss is the most common complaint in dermatology (specially females). It causes a significant psychosocial distress and decreased quality of life in affected patients and exists in different types, but the most common types are androgenetic alopecia and telogen effluvium (TE). Although there are many treatments with highest levels of medical evidence, but patients who exhibit intolerance or poor response to these treatments need additional treatment modalities. To evaluate the efficacy and safety low level laser therapy for female pattern hair loss (FPHL) and TE. A prospective interventional study included 20 female patients, 13 were diagnosed as FPHL, and 7 were diagnosed TE. Patients received two sessions per week with Hair Growth System (TOPHAT655) a bicycle-helmet type device. Treatment session of 20 minutes for 16 successive weeks (total of 32 treatments) with follow-up. Patients were evaluated by software-analyzed trichoscopic images, as the primary endpoint was the percent increase in hair counts from baseline to post-treatment. Global photography and patient satisfaction were determined as a secondary end point. Twenty patients completed the study (13 FPHL, 7 TE). FPHL patients baseline hair counts were 222.3 ± 33.5 (N = 13), in TE patients baseline hair counts were 271.2 ± 39.0 (N = 7). Post-treatment hair counts were 255.3 ± 30.4 (N = 13) In FPHL patients (P = .007), and 294.2 ± 38.1 (N = 7) in TE patients (P = .143). Low level laser therapy of the scalp at 655 nm significantly improved hair counts in FPHL, and there is no significance difference in TE patients with no serious adverse events. Additional studies should be considered to determine the long-term effects of low-level laser therapy treatment on hair growth and maintenance, and to optimize laser modality.

RESUMO

BACKGROUND: To more minimize the minimally invasive valve surgeries, percutaneous vascular access and closure has been used for the establishment of extracorporeal circulation. This study investigates early clinical outcomes of patients who received MANTA for femoral artery closure as first experiences in minimally invasive valve surgery. METHODS: Between January 2019 and July 2019, 103 consecutive patients (mean age: 58 ± 11 years) underwent video-assisted minimally invasive valve surgery through right anterior minithoracotomy at two cardiac surgery referral centers in Germany. Percutaneous cannulation for cardiopulmonary bypass and femoral artery closure with MANTA were performed in all patients: 18-F and 14-F MANTA were used in 88 (85.4%) and 15 (14.6%) patient, respectively. Mitral, aortic, tricuspid, and double valve surgeries were performed in 51 (49.5%), 39 (37.9%), 7 (6.8%), and 6 (5.8%), patients, respectively. Clinical data were prospectively entered into our institutional database. RESULTS: Cardiopulmonary bypass time and cross-clamping time were 69 ± 23 and 38 ± 14 minutes, respectively. Except for two patients with late pseudoaneurysm on 15th and 23th postoperative day, neither major nor minor vascular complications nor vascular closure device failure according to the Valve Academic Research Consortium-2 definition criteria was observed. Additionally, no wound healing disorders or conversion to surgical closure was observed. CONCLUSIONS: MANTA as percutaneous femoral artery closure after decannulation of cardiopulmonary bypass is a safe, feasible, and effective approach and yields excellent early outcomes. Larger size studies are needed to evaluate more the efficacy and safety of MANTA.

RESUMO

The development of sustainable routes to the bio-manufacture of gaseous hydrocarbons will contribute widely to future energy needs. Their realisation would contribute towards minimising over-reliance on fossil fuels, improving air quality, reducing carbon footprints and enhancing overall energy security. Alkane gases (propane, butane and isobutane) are efficient and clean-burning fuels. They are established globally within the transportation industry and are used for domestic heating and cooking, non-greenhouse gas refrigerants and as aerosol propellants. As no natural biosynthetic routes to short chain alkanes have been discovered, de novo pathways have been engineered. These pathways incorporate one of two enzymes, either aldehyde deformylating oxygenase or fatty acid photodecarboxylase, to catalyse the final step that leads to gas formation. These new pathways are derived from established routes of fatty acid biosynthesis, reverse ß-oxidation for butanol production, valine biosynthesis and amino acid degradation. Single-step production of alkane gases in vivo is also possible, where one recombinant biocatalyst can catalyse gas formation from exogenously supplied short-chain fatty acid precursors. This review explores current progress in bio-alkane gas production, and highlights the potential for implementation of scalable and sustainable commercial bioproduction hubs.

RESUMO

Pityriasis versicolor (PV) is a chronic superficial fungal infection. Management using azole drugs leads to drug resistance. The present study aimed to compare the clinical outcome of 0.1% adapalene gel vs 2% ketoconazole cream and their combination in PV. This randomized double-blinded study was conducted on 90 PV patients divided into three equal groups. GI was treated with topical ketoconazole 2% cream twice daily and placebo, GII was treated with topical 0.1% adapalene gel twice daily and placebo and GIII was treated with topical combination of 0.1% adapalene gel (at night) and ketoconazole 2% cream (in the morning). All patients received medications for 4 weeks. Evaluation was done at 2 and 4 weeks and included clinical assessment, laboratory assessment, and patient satisfaction. We found that after 4 weeks of treatment, all groups showed significant improvement. There was better response in GIII in terms of lower rate of positive potassium hydroxide staining, higher rate of significantly improved cases and higher rate of well-satisfied patients. However, the difference fell short of statistical significance. We concluded that a combination of adapalene gel and ketoconazole cream is very effective in treatment of PV with no or mild side effects.

RESUMO

INTRODUCTION: A rapidly evolving evidence suggests that smell dysfunction is a common symptom in COVID-19 infection with paucity of data on its duration and recovery rate. OBJECTIVES: Delineate the different patterns of olfactory disorders recovery in patients with COVID-19. METHODS: This cross-sectional cohort study included 96 patients with olfactory complaint confirmed to be COVID-19 positive with recent onset of anosmia. All patients were inquired for smell recovery patterns using self-assessment questionnaires. RESULTS: Ninety six patients completed the study with mean age 34.26 ±â€¯11.91 years. Most patients had sudden anosmia 83%. Loss of smell was accompanied by nonspecific inflammatory symptoms as low-grade fever (17%) and generalized body ache (25%). Nasal symptoms were reported by 33% of patients. Some patients reported comorbidities as D.M (16%), hypertension (8%) or associated allergic rhinitis (25%), different patterns of olfactory recovery showed 32 patients experiencing full recovery (33.3%) while, 40 patients showed partial recovery (41.7%) after a mean of 11 days while 24 patients (25%) showed no recovery within one month from onset of anosmia. CONCLUSION: The sudden olfactory dysfunction is a common symptom in patients with COVID-19. Hyposmia patients recover more rapidly than anosmic ones while the middle age group carried the best prognosis in olfactory recovery. Females possess better potentiality in regaining smell after recovery and the association of comorbidities worsen the recovery rate of olfactory dysfunction in patients with COVID19. LEVEL OF EVIDENCE: Level 2b a cross-sectional cohort study.

RESUMO

BACKGROUND: Suture-less aortic valves aim to achieve better outcomes and to aid and facilitate the minimally invasive aortic valve replacement procedure by tackling the issue of cross-clamp time, which is an independent predictor of postoperative outcomes, especially in patients with serious comorbidities. By reducing the number of sutures, the time for suture placement is reduced. Our meta-analysis tried to assess the safety and haemodynamic performance of the suture-less aortic valve prostheses to ascertain their benefits as a viable alternative to current established measures. METHOD: From their inceptions to February 2017, six electronic databases were searched. Relevant studies using commercially accessible suture-free valves to replace the aortic valve have been recognised. Based on the predefined endpoints, data were collected and analysed. RESULTS: For incorporation in qualitative and quantitative analyses, 24 studies were recognised, with a total number of 5,073 patients undergoing suture-less aortic valve replacement. Mortality incidence at the 30-day and 12-month follow-ups were 2.5% and 2.7%, respectively, while the incidences of thromboembolic events (1.6%) and paravalvular leak (0.5%) were acceptable. CONCLUSIONS: Current available evidence indicates that sutureless aortic valve replacement is a safe operation showing low mortality and complication rates, with satisfactory haemodynamic performance.

RESUMO

A cross-sectional survey was conducted in Egypt from November 2015 to June 2016. Sexually active adult men were interviewed by a questionnaire designed by the authors. All the participants were evaluated by the abridged 5-item version of the International Index of Erectile Function (IIEF). A total of 3,000 sexually active Egyptian males participated in this study, 946 (31.53%) reported using PDE5Is at least once, and 2054 (68.47%) have never used them. The majority of those who used PDE5Is obtained them for recreational purposes mainly for pleasure (58.35%) and to increase duration/frequency of the intercourse (15.6%). Only 26.05% used PDE5Is to treat ED. The main source of obtaining PDE5Is was friends, relatives and colleagues (62.79%); 25.16% of users obtained the drug by themselves, and 6.66% were prescribed the drug by a pharmacist. Only 5.39% of users obtained the drug after a specialist physician consultation. Sildenafil was the most commonly used PDE5I (90.6%), and most of the users (88.05%) used them in an occasional manner even in the presence of erectile dysfunction, while 11.95% used the drug in a regular manner for every intercourse. PDE5Is are frequently used by the Egyptian male population, and most of them seemed to take them as recreational medications.

RESUMO

Unlike the epidermis, which regenerates continually, hair follicles anchored in the subcutis periodically regenerate by spontaneous repetitive cycles of growth (anagen), degeneration (catagen), and rest (telogen). The loss of hair follicles in response to injuries or pathologies such as alopecia endangers certain inherent functions of the skin. Thus, it is of interest to understand mechanisms underlying follicular regeneration in adults. In this work, a phytochemical rich in the natural vitamin E tocotrienol (TRF) served as a productive tool to unveil a novel epidermal pathway of hair follicular regeneration. Topical TRF application markedly induced epidermal hair follicle development akin to that during fetal skin development. This was observed in the skin of healthy as well as diabetic mice, which are known to be resistant to anagen hair cycling. TRF suppressed epidermal E-cadherin followed by 4-fold induction of ß-catenin and its nuclear translocation. Nuclear ß-catenin interacted with Tcf3. Such sequestration of Tcf3 from its otherwise known function to repress pluripotent factors induced the plasticity factors Oct4, Sox9, Klf4, c-Myc, and Nanog. Pharmacological inhibition of ß-catenin arrested anagen hair cycling by TRF. This work reports epidermal E-cadherin/ß-catenin as a novel pathway capable of inducing developmental folliculogenesis in the adult skin.

RESUMO

AIM: The aim of this work is to assess the effectiveness of hysteroscopic tubal occlusion using iso-amyl-2-cyanoacrylate, among infertile women with hydrosalpinx prior to in vitro fertilization (IVF). METHODS: Hysteroscopic injection of fallopian tubes with hydrosalpinx by 0.5 mL iso-amyl-2-cyanoacrylate was done in 40 infertile women planning for IVF. The patients were then followed-up after 1 and 3 months, with hysterosalpingography (HSG) to confirm complete tubal occlusion. Reinjection with iso-amyl-2-cyanoacrylate was done in these patients with incomplete tubal occlusion after 1 month of the first injection, followed by HSG 2 months later to confirm complete tubal occlusion. Data were prescribed as range, mean and standard deviation (for parametric variables) and range, number and percentage (for categorical variables). RESULTS: The total number of tubes injected in this study was 54, 42 (77.8%) of which were completely occluded after one injection while 12 (22.2%) were partially occluded. Reinjection of the partially occluded tubes was done, and (HSG) of all patients after 3 months of the primary injection confirmed 48 (88.9%) of the tubes completely occluded while 6 (11.1%) remained partially occluded. Thirty-two (80%) patients underwent one cycle of IVF/ET (embryo transfer), while 8 (20%) patients did not appear for follow-up. Among the patients who underwent IVF/ET, 24 (75%) got pregnant, while 8 (25%) failed to conceive. Among the pregnant patients, 8 (33.3%) delivered at term, 3 (12.5%) had first trimester abortion, while the remaining 13 (54.2%) did not deliver yet. CONCLUSION: Iso-amyl-2-cyanoacrylate used for hysteroscopic tubal occlusion in patients with hydrosalpinx prior to IVF is safe and effective.

RESUMO

OBJECTIVES: Assessment of adding lidocaine to dexamethasone in the intratympanic injections for the treatment of subjective idiopathic tinnitus (SIT). METHOD: A prospective, controlled, randomized, double-blind study of forty-four patients with SIT diagnosed in the Department of Otolaryngology, Tanta University Hospital, a tertiary academic medical centre from March 2015 to October 2016. 44 patients were recruited in the study and were categorized into two groups; (A) included 22 patients managed with ITLD, and (B) included 22 patients managed with intratympanic postoperative ITD injection. Intratympanic injections were double-blind performed three times with one weak interval. After three and six months, the tinnitus improvement was studied using the following parameters: Arabic tinnitus questionnaires (ATQ), loudness matching test and Tinnitus handicap index (THI). RESULTS: The effectiveness rates of ITLD for idiopathic tinnitus reported in the ATQ, THI, and in the loudness matching test were 74.5% in the ITDL group and 50.0%, 50.5%, and 40.0% in the ITD group, respectively. Statistically, there was a significant difference between both groups in 6 months duration. CONCLUSION: ITLD seems to be effective for SIT than ITD alone. The indication of ITLD for tinnitus needs to be limited to specific cases of resistant medical treatment.
