Treatment possibilities for acquired and hereditary diseases by gene therapy: a review

Therapeutic nucleic acids demand specificity and accuracy in design as well as delivery strategies used in replacement or silencing of the target gene. Gene therapy is believed to be the therapy in which the root cause of the diseases can be treated at the molecular level. Generally gene therapy helps in the identification of the origin of the disorder instead of using drugs to diminish or control the symptoms. The application of nucleic acids to treat and control diseases is known as “gene therapy.” Gene therapy consists on the substitution or addition of a functional gene into the nucleus of a living cell, in order to treat a disease or repair a dysfunction, caused by this gene failure. This therapy is used to correct defective genes, which are responsible for genetic diseases. Thus, gene therapy can be used to prevent, treat or regulate hereditary or acquired disorders, by the production of therapeutic proteins. The gene therapy is mediated by the use of viral and non-viral vectors to transport foreign genes into somatic cells to restorative defective genes. This review focuses on viral vectors in detail.

Anti-ulcer activity of psidium guajava on pylorus ligation induced gastric ulcer in albino rats

The present study deals with the phytochemical analysis and evaluation of antibacterial activity of hydroalcohol, acetone, and hexane extracts of the leaves of Psidium guajava. The antimicrobial activity was measured by the agar well diffusion method. Gastric volume, pH, total and free acidity and the ulcerative index was also measured in hydroalcoholic extract of Psidium guajava on gastric ulcer pyloric ligation in rat. Glycosides, terpenoids, and tannins are only present in the hydro alcohol extract. The extracts are tested against gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus, Bacillus subtilis) bacterial strains. The zone of inhibition against microorganisms is direct proportional to the concentration of extract. Maximum zone of inhibition (24mm) against Staphylococcus aureus except hexane extract was seen. Psidium guajava leaves show maximum phytochemicals compounds and inhibition of microorganisms in hydroalcoholic extract. So the hydroalcoholic extraction was used for anti-ulcer activity. The present study was performed in pylorus ligation induced gastric ulcer model in albino rats in which the ability of hydroalcoholic extracts of Psidium guajava was tested at a dose level of 400 mg/kg body weight orally and compared with Ranitidine (10 mg/kg) as standard. From the results it is concluded hydro alcohol leaf extracts of Psidium guajava 400 mg/kg dose level showed significant anti-ulcer activity when compared to that of standard drug.

The effects of different forms of risk communication on judicial decision making

When mental health experts provide information to courts on the results of a risk assessment conducted on a defendant or patient, they engage in “risk communication.” We examined the effects of four different forms of risk communication (prediction, categorical, risk factors/risk management, or hybrid) on judges’ (n = 253) perceptions of risk assessment evidence introduced in a case where they must decide whether to release from the hospital an individual found not guilty by reason of insanity. Judges who received information in the risk factors/risk management form were more likely to release the patient than were those who received prediction-based or categorical risk information. Judges with greater experience hearing cases involving risk assessment evidence were also more likely to release. Moreover, judges who had positive attitudes towards risk assessment and social science evidence in general, were more likely to find the risk assessment evidence introduced in the particular case to be understandable, relevant, and dispositive. Implications of the results for how mental health experts communicate risk information to the courts are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Determine the relationship between hypertension and uterine fibroids

Background: Numerous studies have linked uterine fibroids to hypertension, suggesting that this condition may be a risk factor unique to women. These days, fibroids are the main cause of myomectomy and hysterectomy. This study aimed to ascertain the relationship between uterine fibroids and hypertension in Saudi women. Methods: This case-control study was carried out between January 2023 and January 2024 on patients with uterine fibroids and non-uterine fibroids who had an appointment for surgery at the gynecological department of the Maternal and Children Hospital (MCH) Sakaka, Aljouf, Saudi Arabia. Blood pressure readings and fibroid diameters are important factors in studying uterine fibroids. Results: The 140 individuals who were split into 70 cases and 70 control groups had average ages of 41.62±2.16 and 44±1.10. 95 participants had menorrhagia, which was the most common ailment in both groups. In contrast to the controls, the uterine fibroid cases had significantly higher rates of anemia (54.2%), OCP (12.8%), infertility (11.4%), and abortion (37.1%) (P<0.001). 48.5% of uterine fibroids had hypertension, compared to 17.1% of controls (P<0.001).Conclusion: There is a considerable relationship between uterine fibroids and hypertension. Anemia, infertility, and abortion are higher in uterine fibroid cases.

Budd-chiari syndrome in gaucher disease type iii in an adult libyan male: letter to the editor

Gaucher Disease (GD) is the most common lysosomal storage disorder. The prevalence of GD is approximately 1/100,000, and type III GD accounts for 5% of cases. [1] It is an autosomal recessive disease due to a GBA gene mutation, leading to glucocerebrosidase enzyme deficiency. [1,2] Gaucher disease (GD) is categorized into three types according to clinical presentation: [3] Type I, which is non-neuronopathic and most common, particularly among Ashkenazi Jews; Type II, which is acute neuronopathic and marked by significant neurological involvement and high mortality rates; and Type III, which is subacute neuronopathic, exhibiting both systemic and neurological symptoms. In this report, we discuss a 24-year-old man from Libya diagnosed with GD type III. His diagnosis was established at the age of one due to symptoms including pallor, poor appetite, and hepatosplenomegaly. Laboratory tests indicated a hemoglobin level of 5.6 g/dL, chitotriosidase activity of 18,742 μmol/L, and an angiotensin-converting enzyme level of 251 UI/L. Genetic analysis confirmed a homozygous L444P mutation. He underwent splenectomy at the age of three, and enzyme replacement therapy (ERT) was administered intermittently with regular follow-ups until 2011. In December 2023, the patient experienced two weeks of abdominal pain, distension, and fatigue. A physical examination revealed ascites, dilated abdominal veins, and an enlarged liver and spleen.

Secured scheduling techniques of network resource management in vehicular communication networks

Scheduling is the need of every project. Without scheduling, projects don’t fulfill time constraints, go over spending plan. It is a process utilized by teams to organize and structure their resources so the tasks they need to complete are scheduled based on availability and capability. This process is more beneficial if it is required to allocate and assign task to the resources without allocating their schedules. This paper reviews different types of network scheduling techniques, which are used to schedule a task. These techniques are very effective and help us to preplan the whole scheduling process

Risk factors associated with preterm birth of women who gave birth in abia state university teaching hospital, aba, southeast, nigeria

Background: Preterm birth remains a leading cause of neonatal morbidity and mortality worldwide. Identifying its risk factors is essential for developing targeted interventions to improve maternal and neonatal health. This study investigated the sociodemographic, obstetric, medical, and lifestyle risk factors associated with preterm birth among women who delivered at Abia State University Teaching Hospital (ABSUTH), Aba, Southeast Nigeria. Methods: A hospital-based case-control study was conducted at ABSUTH. The study population comprised all the women who gave birth at the facility who met the criteria. Data were collected through structured interviewer-administered questionnaires and medical record reviews. Key variables included maternal age, education level, socioeconomic status, obstetric history, medical conditions, lifestyle factors, and antenatal care utilization. Descriptive statistics, chi-square tests, t-tests, and logistic regression were performed using SPSS version 25, with statistical significance set at p < 0.05. Results: A total of 9125 deliveries were recorded during the period of this study, including 1,962 cases (preterm births, <37 weeks gestation) and 7,163 controls (term births, ≥37 weeks gestation). Chi-square analysis showed significant associations between preterm birth and maternal age (p < 0.05), low education level (p < 0.001), low socioeconomic status (p = 0.0351), previous preterm birth (p < 0.001), short pregnancy interval (p < 0.001), hypertension (p < 0.001), diabetes (p < 0.001), infections (p < 0.001), smoking (p < 0.001), alcohol consumption (p < 0.001), and inadequate antenatal visits (p < 0.001). Logistic regression confirmed that hypertension, diabetes, infections, previous preterm birth, and inadequate antenatal visits were independent predictors of preterm birth. Conclusion: The findings highlight the multifactorial nature of preterm birth, with medical conditions, lifestyle behaviors, and inadequate antenatal care playing crucial roles. Early identification and management of these risk factors through improved maternal health services and health education may reduce the burden of preterm birth in the study setting.

Pdf - attention is all you need

The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 Englishto-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.0 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.

Techniques, indications, and complications of kidney biopsy: a narrative review

Accurate diagnosis of the cause of acute or chronic kidney dysfunction may require a percutaneous kidney biopsy (PKB). Unfortunately, the invasive nature of the procedure can lead to potential complications that may discourage the KBs. Lack of appropriate communication skills, experienced personnel and equipment, and high procedure costs can negatively impact complication rates and the frequency of conducted KBs. This nonsystematic review assesses KB procedures, indications, contraindications, complications, post-KB monitoring time, and cost. We looked for reviews and original articles published between January 2010 and Jan 2025 on Google, Google Scholar, and PubMed. Different keywords, phrases, and sentences include PKB, renal biopsy, native PKB, ultrasound guide, CT-guided, PKB, allograft PKB, and PKB procedures. KB makes histopathological and immunohistological diagnosis possible, which are necessary for diagnosis and treatment. It is often used despite the known complications. KB and other biochemical assays have tracked transplant rejection and antirejection drugs. Automatic gun spiral needles sizes 14 and 16 capture enough samples with fewer complications than gauge sizes 18 and 20. KB cost is another issue, especially in low-income areas, and deserves additional study.

Translanguaging and reading comprehension of filipino esl intermediate learners

This study investigated the connection between translanguaging and reading comprehension of Filipino ESL intermediate learners. The respondents were intermediate pupils enrolled in the selected central schools in Bicol, Philippines. The respondents' ages range from 8 to 12 years old, and 124 students (27.55%) were males while 326 students (72.44%) were females. The descriptive-correlational method was used in the study. The descriptive method was used to describe the reading performance of the ESL intermediate learners and their translanguaging factors, while Pearson Product Moment Correlation was used to determine the relationship between the two variables. The primary instruments used were validated teacher-made reading comprehension test and translanguage factors survey questionnaire. Data disclosed that the general reading comprehension of the ESL intermediate learners along with vocabulary, drawing inferences, and getting the main idea, are very satisfactory. Meanwhile, the different translanguaging factors, along with personal, teacher, and social, were surveyed and identified in the study. The statistical test revealed that the reading comprehension of the respondents was significantly correlated with the identified translanguaging factors. Thus, it is recommended that teachers should promote group discussions and allow open interactions in the classroom. Teachers should allow the use of both the home language and English; employ translanguaging pedagogy in teaching reading; foster an understanding and acceptance of linguistic differences; promote multilingualism, and allow indigenous languages to be used in education to facilitate meaningful learning.

Review on the cardioprotective role of pinocemrin in atherosclerosis, myocardial infarction and related vascular-myocardial remodeling

Cardiovascular diseases represent a formidable global health challenge, standing as the foremost cause of both mortality and morbidity. Atherosclerosis and myocardial infarction, as primary contributors to this epidemiological burden, underscore the urgent need for effective therapeutic interventions with minimal side effects. Natural compounds derived from plants have emerged as promising candidates, given their enhanced efficacy and reduced adverse effects. Phytochemicals, in particular, have garnered attention for their potential as alternative therapeutic agents. This review delves into the cardioprotective potential of pinocembrin (5,7-Dihydroxy flavanone), a compound extracted from various plants and honey. Renowned for its antioxidant and anti-inflammatory properties, pinocembrin demonstrates significant cardioprotective effects through the modulation of diverse signaling pathways. Atherosclerosis and myocardial infarction entail intricate cellular mechanisms involving oxidative stress, inflammatory responses, cellular remodeling, and programmed cell death. Pinocembrin, by targeting key factors within these pathways, exhibits cardioprotective actions. While existing research underscores its effectiveness, further investigations are warranted to elucidate the impact of pinocembrin on additional cardiovascular conditions and explore novel molecular targets, thus paving the way for future advancements in therapeutic interventions.

Exploring performance parameters of artificial allosteric protein switches

Biological information processing networks rely on allosteric protein switches that dynamically interconvert biological signals. Construction of their artificial analogues is a central goal of synthetic biology and bioengineering. Receptor domain insertion is one of the leading methods for constructing chimeric protein switches. Here we present an in vitro expression-based platform for the analysis of chimeric protein libraries for which traditional cell survival or cytometric high throughput assays are not applicable. We utilise this platform to screen a focused library of chimeras between PQQ-glucose dehydrogenase and calmodulin. Using this approach, we identified 50 chimeras (approximately 23% of the library) that were activated by calmodulin-binding peptides. We analysed performance parameters of the active chimeras and demonstrated that their dynamic range and response times are anticorrelated, pointing to the existence of an inherent thermodynamic trade-off. We show that the structure of the ligand peptide affects both the response and activation kinetics of the biosensors suggesting that the structure of a ligand:receptor complex can influence the chimera's activation pathway. In order to understand the extent of structural changes in the reporter protein induced by the receptor domains, we have analysed one of the chimeric molecules by CD spectroscopy and hydrogen-deuterium exchange mass spectrometry. We concluded that subtle ligand-induced changes in the receptor domain propagated into the GDH domain and affected residues important for substrate and cofactor binding. Finally, we used one of the identified chimeras to construct a two-component rapamycin biosensor and demonstrated that core switch optimisation translated into improved biosensor performance.

Covid19 vaccine production in india – changing market scenario

India is in the midst of a severe second wave of Covid-19. As per the Global Commission for Post-Pandemic Policy by mid-April of 2021, India had manufactured nearly 17 percent of all Covid-19 vaccine doses globally. It was the world’s fourth-largest producer, after China (about 36 percent), the United States (about 22 percent) and the European Union (more than 17 percent). Even so, following a shortage of vaccines and with insufficient local production, Government of India decided to import more foreign vaccines with quicker approval process for vaccines accepted in US/EU markets. India is currently using made-in-India vaccines, namely, Covishield manufactured by Serum Institute India and Covaxin of Bharat Biotech in its COVID-19 immunisation programme. The shortcoming in the production of vaccines and its dissemination within the country urges one to understand who the local producers are and how the market is playing out. This paper looks at the evolving market structure of vaccine production in India in the textbook framework of an oligopoly market. We use secondary data sources and daily newspaper briefs.

Ecofriendly synthesis of pure and modified cumno3: it’s application as gas sensor

Recently, novel materials like gas-sensing metal oxides, mixed metal oxides, and modified mixed metal oxides have attracted great attention owing to their key roles in monitoring environmental pollution, security in hospitals, homes, and public places, and hazardous emissions from industries and automobile exhaust. Initially, the mechanochemical (MCh) method was employed for the synthesis of the CuMnO3 catalyst and then the modification of CuMnO3 through the hydrothermal route. These synthesized catalysts were characterized by Ultraviolet Violet-Diffused Reflectance (UV-DRS) spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The average particle size obtained for 3 % Fe/CuMnO3 was found to be 14–28 nm. The present work proclaimed that among all the synthesized 1,3,5 % Fe/CuMnO3 materials, the 3 % Fe modified CuMnO3 material shows significant gas sensing properties towards highly toxic H2S gas released from sewage plants, oil, and natural gas industries, among NH3, CO2, H2S, H2, CO2 and Cl2 with moderate temperature requirements and excellent selectivity.
