Nucleic acid-based therapy has become an increasingly important strategy for treating a variety of human diseases. In systemic therapy, a therapeutic gene must be delivered efficiently to its target tissues without side effects. To deliver a therapeutic gene such as plasmid DNA (pDNA) or small interfering RNA (siRNA) to target tissues by systemic administration, cationic carriers such as cationic liposomes and polymers have been commonly used as a non-viral vector. However, the binary complex of therapeutic gene and cationic carrier must be stabilized in the blood circulation by avoiding agglutination with blood components, because electrostatic interactions between positively charged complexes and negatively charged erythrocytes can cause agglutination, and the agglutinates contribute to high entrapment of the therapeutic genes in the highly extended lung capillaries. One promising approach for overcoming this problem is modification of the surface of cationic complexes with anionic biodegradable polymers such as hyaluronic acid, chondroitin sulfate, or polyglutamic acid. As another approach, we recently developed a sequential injection method of anionic polymer and cationic liposome/therapeutic gene complex (cationic lipoplex) for delivery of a therapeutic gene into the liver or liver metastasis. In this review, we describe recent advances in the delivery of therapeutic genes by lipid- and polymer-based carrier systems using anionic polymers.

Evaluation of semen characteristics is an important and prior for semen preservation. The aim of this study was to collection and evaluation of indigenous buck semen in the coastal region of Bangladesh. The semen was collected from bucks through artificial vagina method. The colour, odour, volume, viscosity, mass activity, consistency, concentration and individual sperm motility were analysed and recorded after collection from pre-selected four bucks. The colour and odour of all buck (B) semen were creamy white to milky white and fishy smell, respectively. In this study, we found that the average volume of B-1, B-2, B-3 and B-4 were 0.74, 0.98, 0.42 and 0.60 ml, respectively. The average grading of viscosity of B-1, B-2, B-3 and B-4 were 3.2, 3.8, 2.6 and 3.0, respectively. The average grading of mass activity of B-1, B-2, B-3 and B-4 were 3.6, 3.2, 2.4 and 3.4, respectively. The consistency of B-1, B-2, B-3 and B-4 were 4.2, 4.8, 2.8 and 4.0, respectively. The concentration of B-1, B-2, B-3 and B-4 were 1.58, 1.94, 0.62 and 1.54 ×109 per ml of semen volume. The average percentage of individual sperm motility of B-1, B-2, B-3 and B-4 were 81, 71, 66 and 80%, respectively. Viscosity, mass activity, consistency, concentration and individual sperm motility were significantly (p < 0.05) correlate with each other. It may be concluded that the data about semen of the bucks are in acceptable level for preservation. Further study will be designed for the evaluation of viability and motility of sperm before and after freezing as liquid semen.

Background/aim: Amitriptyline belongs to class of known as tricycline antidepresant (TCA) that is being used to treat anxiety and depressive states. It may help improve mood and feelings of well-being, relieve anxiety and tension, help to improve sleep and increase energy level. The study investigated the effect of amitriptyline on learning and memory using eighteen (18) healthy Swiss mice of both sexes weighing 16 – 25 g. Method: The animals were divided into three (3) groups consisting of six (6) animals each. Group 1 served as the control group, Group 2 was administered with amitriptyline at a dose of 3 mg/kg body weight dissolved in 3 mls of distilled water, and used to test for learning, while Group three was also given similar administration like Group 2, but used to test for memory. All the animals were tested for learning and memory performance using Novel object recognition task and Morris water maze test. Results: The results obtained from the Novel object recognition task showed that there was a significant decrease (p < 0.05) in total object approach in acquisition trial of amitriptyline treated group when compared to the acquisition trial of the control group. There was a significant decrease (p < 0.05) in retention trial of amitriptyline group when compared to retention trial in the control group. There was a significant decrease (p < 0.05) in total duration exploring objects in acquisition trial of amitriptyline treated group when compared to the acquisition trial of the control group. There was a significant increase (p < 0.05) in total duration exploring objects in retention trial of amitriptyline treated group when compared to the retention trial of the control group. There was a significant decrease (p < 0.05) in the index of habituation of amitriptyline treated group when compared to the control group. The index of discrimination showed a significant increase (p < 0.05) in amitriptyline treated group when compared to the control group and a significant decrease (p < 0.05) in amitriptyline group when compared to the control group. In the Morris water maze test, Day 1 – 3 were for acquisition training, day 4 – 6 reversal training, day 7 the probe trial day and day 8 the visible platform day. During acquisition training in the Morris water maze test, there was no significant difference in Swim latencies in day 1 and 2. However in day 3, there was a significant increase (p < 0.05) in swim latency of group compared to control group and a significant decrease (p < 0.05) in swim latency of amitriptyline treated group compared to the control group. During reversal training in day 1, 2 and 3, there was no significant difference in swim latency among the three groups. Results for the retention quadrant in the probe trials showed a significant decrease (p < 0.01) in amitriptyline group when compared to the control group. Conclusion: Results suggest that amitriptyline impairs learning and memory functions.

Background: WHO grade II Low-grade gliomas (LGGs) need multi-disciplinary treatment from different specialties, directed by new molecular classifications and prognostic markers. Yet regional practice patterns and obstacles are not reported, especially in MENA countries.Method: A cross-sectional survey of physicians from MENA countries (including neurosurgeons, radiation oncologists, and medical oncologists) was conducted. An electronic anonymous survey, including clinical scenarios and evidence-based treatment choices, was distributed at professional conferences. The feedback included responses regarding surgical interventions, adjuvant treatment preferences, and barriers to adoption of IDH-mutant inhibitors.Results: 137 physicians (37.23% neurosurgery, 32.85% radiation oncology, 29.93% medical oncology). Most had 6–15 years of experience (56.21%) and worked in government (51.82%) or academic hospitals (25.55%). Maximal safe resection (MSR), if applicable, was preferred over biopsy (89.05% vs. 10.95%). For residual Astrocytoma, concurrent radiotherapy (RT) with temozolomide (TMZ) (42.34%) was the preferred adjuvant, while 44.53% prefer observation after gross total resection (GTR). For residual Oligodendroglioma, RT followed by PCV (45.99%) was preferred, with 59.85% offered observation post-GTR. Most (96.35%) agreed that resection extent impacts outcomes, while 72.99% objected to extending TMZ beyond six cycles. High-risk stratification varied: 46.72% used age ≥40 years, and 88.32% prioritized residual tumor volume. Although 64.96% supported IDH-mutant inhibitors, 58.39% cited limited availability as a barrier, followed by cost (40.88%) and insufficient long-term data (31.39%). Specialty-specific differences emerged: radiation oncologists tend more to provide adjuvant radiotherapy in the context of persistent seizure post-operatively (χ² = 20.50, p < 0.05), and medical/radiation oncologists more often used age ≥40 for high-risk stratification (χ² = 10.10, p = 0.038).Conclusion: There is a wide variation in the WHO grade II LGGs management among physicians in MENA Countries. These data highlight the importance of locally derived guidelines, the increased availability of molecularly directed therapies, and ongoing collaboration between multiple disciplines to ensure optimal patient outcomes.Key points:•    Maximal safe resection (89.05%) is the dominant surgical approach for WHO grade II LGGs, taking into consideration the location and extent of infiltration, among specialists in MENA Countries, reflecting global consensus on resection extent impacting outcomes (96.35% agreement).•    Adjuvant therapy preferences vary: concurrent RT+TMZ for astrocytomas (42.34%) and sequential RT+PCV for oligodendrogliomas (45.99%), with 59.85% observing post-GTR in oligodendrogliomas.•    IDH-mutant inhibitors (e.g., Vorasidenib) are supported by 64.96% of oncologists, but limited availability (58.39%) and cost (40.88%) hinder adoption.Importance of the study: This multicenter survey is the first to evaluate real-world management trends and barriers for WHO grade II low-grade gliomas (LGGs) among physicians in MENA Countries. While all specialists align with international guidelines in surgical strategies (e.g., maximal safe resection), significant heterogeneity exists in adjuvant therapy choices, particularly for astrocytomas versus oligodendrogliomas. Crucially, we identify systemic barriers—such as limited access to molecular therapies (IDH inhibitors) and cost constraints—that disproportionately affect WHO grade II LGGs care in the MENA Countries. Our findings underscore the urgent need for regionally adapted guidelines and multidisciplinary collaboration to standardize practices aligned with international guidelines. By highlighting disparities in resource availability and specialty-specific decision-making (e.g., radiation oncologists prioritizing post-resection seizures, p < 0.05), this study provides a roadmap for optimizing WHO grade II LGGs management in resource-limited settings and advocates for the inclusion of Arab populations in global trials of novel agents like Vorasidenib.

Introduction: Ankle sprain is a widespread impairment in sport groups; this impairment leads to an absence from the workplace. The ankle sprains incidence rates are induced by height, weight, BMI, physical fitness, level of match, classification of sport, and personal exposure to sport. Methods: A longitudinal case-control study was executed to verify the outcome of risk factors for ankle sprain at a Military Male School between 2012 and 2013 of 4987 people at risk for ankle sprain, a total of 234 cadets sustained new ankle sprains during the study, 432 non-injured cadets randomly selected as the control group. Results: Regarding to the total people at risk in our study the incidence rate was approximately 5/1000 ankle sprain-years. Cadets with ankle sprains had higher weight, BMI and higher scores in Army Physical Fitness test than the control group. Ankle sprain occurred most commonly during athletics (51.4%). Ankle sprain incidence rate did not significantly vary from different athletic competitions after controlling for athlete-exposure. Soccer and Ball Games had the highest ankle sprain incidence rate. Conclusion: Higher weight, increased BMI, greater physical conditioning and athlete exposure to selected sports were all risk factors for ankle sprain.

A thought-provoking debate in the popular literature concerning vaccination has blossomed in recent years [1-6]. While “traditionalists” support universal immunization against a variety of infectious diseases, many influential individuals hold that vaccinations do far more harm than good. The web sites vactruth.com and anhinternational.org are typical web sites to visit to understand their concerns.  More details on the debate, offering commentary on both sides of the issue, can be explored at wikipedia.org/wiki/Vaccine_controversies. In essence, however, those arguing for the universal use of vaccines point to the many millions of lives saved since mass immunization programs were introduced and further argue that resistance to routine vaccination is almost always based on false information. Those arguing against the routine use of vaccines usually either contend that the vaccines are unsafe (often maintaining that vaccine components such as formaldehyde or thimerosal are highly toxic) or alternately argue that governments simply do not have the moral authority to encroach on an individual’s freedom to make medical decisions for themselves or for their children.

Ventricular Septal Defect, also known as VSD is a rare and life-threatening complication associated with MI. Therefore, it should be immediately diagnosed and treated. Transcatheter closure of the ventricular septal defect is a new alternative treatment approach compared to surgery. In this case, we presented a patient with post-infarct basal ventricular septal defect whose ventricular septal defect was closed using an atrial septal defect closure device. The ability to successfully close such a large defect via catheter is promising for the treatment of patients with VSD.

Diabetes mellitus increases the possibility of different cancers. Scientists have substantiated the link of diabetes with increased prevalence, augmented progression and improved cancer aggression. Research has strengthened link of diabetes with the colorectal cancer risk among various cancers. Diagnosis and treatment have made some progress in recent years, but Colorectal is major issue for the health of people even today. In order to reduce cancer mortality, there is importance of prophylaxis, evaluation and proper treatment. Factors distressing cancer prognosis is required by policy-making system for beneficial approaches of cancer patients and improvement of disease. Eventually diabetes- specific strategies for different cancers are explored.

Background: Pseudomonas aeruginosa is one of the top five pathogens causing healthcare-associated infections. Biofilm formation is nowadays a major problem. Aim: The aim of this study was to examine the prevalence of virulence genes in clinical isolates of Pseudomonas aeruginosa at Suez Canal University Hospitals with respect to the site of infection and microbial resistance of the strains. Materials and methods: A cross-sectional descriptive study was carried out on 47 Pseudomonas aeruginosa strains collected from hospitalized patients from December 2015 to August 2017. To detect biofilm formation, we used Tissue Culture Plate Method. The virulence genes (toxA, algD, nan1, pslA and pelA) were amplified using PCR technique. Results: The highest sensitivity was to Imipenem and Ciprofloxacin (85.1% and 68.1% respectively).With respect to the virulence genes, toxA gene was detected in 45 isolates (95.7%), algD gene in 42 isolates (89.4%), pslA in 42 isolates (89.4%) %), pelA cted in 41 isolates (87.2%) and nan1gene was detected in 19 isolates (40.45%). Conclusions and Recommendations: We conclude that there is relationship between virulence genes and biofilm formation in Pseudomonas aeruginosa. We recommend the expansion of work on a larger sample size in a longer period of time.

Loneliness was a major concern of people during the recent COVID-19 pandemic. Now, that the pandemic is mainly gone, it is still a global issue. This commentary reviews the impact on that loneliness has on our cognitive, behavioral and affective functioning. These effects are described, along with the stigma that often accompanies loneliness and which makes it hard for people to acknowledge and admit that they are lonely, and seek help from healthcare professionals. This commentary, aside from describing the various negative implications of loneliness, highlights the need for society to address the issue. While it cannot be eliminated, the population can be taught how to recognize it, and how to offer assistance to those who struggle with it.
