A comprehensive immunobiology review of IBD: With a specific glance to Th22 lymphocytes development, biology, function, and role in IBD.

The two primary forms of inflammatory disorders of the small intestine andcolon that make up inflammatory bowel disease (IBD) are ulcerative colitis (UC) and Crohn's disease (CD). While ulcerative colitis primarily affects the colon and the rectum, CD affects the small and large intestines, as well as the esophagus,mouth, anus, andstomach. Although the etiology of IBD is not completely clear, and there are many unknowns about it, the development, progression, and recurrence of IBD are significantly influenced by the activity of immune system cells, particularly lymphocytes, given that the disease is primarily caused by the immune system stimulation and activation against gastrointestinal (GI) tract components due to the inflammation caused by environmental factors such as viral or bacterial infections, etc. in genetically predisposed individuals. Maintaining homeostasis and the integrity of the mucosal barrier are critical in stopping the development of IBD. Specific immune system cells and the quantity of secretory mucus and microbiome are vital in maintaining this stability. Th22 cells are helper T lymphocyte subtypes that are particularly important for maintaining the integrity and equilibrium of the mucosal barrier. This review discusses the most recent research on these cells' biology, function, and evolution and their involvement in IBD.

The selective and sensitive diagnosis of diseases is a significant matter in the early stages of the cure of illnesses. To elaborate, although several types of probes have been broadly applied in clinics, magnetic nanomaterials-aptamers, as new-generation probes, are becoming more and more attractive. The presence of magnetic nanomaterials brings about quantification, purification, and quantitative analysis of biomedical, especially in complex samples. Elaborately, the superparamagnetic properties and numerous functionalized groups of magnetic nanomaterials are considered two main matters for providing separation ability and immobilization substrate, respectively. In addition, the selectivity and stability of aptamer can present a high potential recognition element. Importantly, the integration of aptamer and magnetic nanomaterials benefits can boost the performance of biosensors for biomedical analysis by introducing efficient and compact probes that need low patient samples and fast diagnosis, user-friendly application, and high repeatability in the quantification of biomolecules. The primary aim of this review is to suggest a summary of the effect of the employed other types of nanomaterials in the fabrication of novel aptasensors-based magnetic nanomaterials and to carefully explore various applications of these probes in the quantification of bioagents. Furthermore, the application of these versatile and high-potential probes in terms of the detection of cancer cells and biomarkers, proteins, drugs, bacteria, and nucleoside were discussed. Besides, research gaps and restrictions in the field of biomedical analysis by magnetic nanomaterials-aptamers will be discussed.

Investigating the Effects of Hydro-alcoholic Urtica Dioica Extract and Retinoic Acid on Follicular Development: An Animal Study.

Background: Urtica dioica (UD), as a natural antioxidant, has positive effects on oocyte maturation. This study aimed to investigate the effects of hydro-alcoholic UD extract and retinoic acid on follicular development in an in vitro fertilization (IVF) condition. Methods: A total of 40 female Wistar rats were randomly divided into 5 groups: group 1 received normal saline, group 2 was given 25 mg/kg retinoic acid, group 3 was administered with 100 mg/kg UD extract, group 4 was treated with retinoic acid plus UD extract, and group 5 received 10 mg/kg olive oil. The histomorphometric parameters were analyzed, including the number of follicles, follicular atrophy, fertilized oocytes, 2-cell embryos, dead embryos, and blastocysts. Results: Retinoic acid caused a significant increase in the primary, preantral, and atretic follicles and a substantial decrease in the corpus luteum compared with the control group (p<0.001). The number of preantral, antral follicles, and corpus luteum was significantly higher in group 3 compared with group 1 (p<0.001). Moreover, coadministration of UD plus retinoic acid (group 4) significantly reduced the atretic follicles (p<0.05). Conclusion: Based on the results, UD herbal extract, as a natural antioxidant agent, could reduce the adverse effects of retinoic acid on oocyte maturation in an IVF condition.

Overview of the role and action mechanism of microRNA-128 in viral infections.

Recently in vivo and in vitro studies have provided evidence establishing the significance of microRNAs (miRNAs) in both physiological and pathological conditions. In this regard, the role of miRNA-128 (miR-128) in health and diseases has been found, and its critical regulatory role in the context of some viral diseases has been recently identified. For instance, it has been found that miR-128 can serve as an antiviral mediator and significantly limit the replication and dissemination of human immunodeficiency virus type 1 (HIV-1). Besides, it has been noted that poliovirus receptor-related 4 (PVRL4) is post-transcriptionally regulated by miR-128, representing possible miRNA targets that can modulate measles virus infection. Of note, the downregulation of seminal exosomes eca-miR-128 is associated with the long-term persistence of Equine arteritis virus (EAV) in the reproductive tract, and this particular miRNA is a putative regulator of chemokine ligand 16 (C-X-C motif) as determined by target prediction analysis. In this review, the latest information on the role and action mechanism of miR-128 in viral infections will be summarized and discussed in detail.

The role of miRNA-128 in the development and progression of gastrointestinal and urogenital cancer.

Increasing data have shown the significance of various miRNAs in malignancy. In this regard, parallel to its biological role in normal tissues, miRNA-128 (miR-128) has been found to play an essential immunomodulatory function in the process of cancer initiation and development. The occurrence of the aberrant expression of miR-128 in tumors and the unique properties of miRNAs raise the prospect of their use as biomarkers and the next generation of molecular anticancer therapies. The function of miR-128 in malignancies such as breast, prostate, colorectal, gastric, pancreatic, esophageal, cervical, ovarian and bladder cancers and hepatocellular carcinoma is discussed in this review. Finally, the effect of exosomal miR-128 on cancer resistance to therapeutics and cancer immunotherapy in certain malignancies is highlighted.

Circulating and dietary advanced glycation end products and obesity in an adult population: A paradox of their detrimental effects in obesity.

Background: The detrimental role of advanced glycation end products (AGEs) against cardio-metabolic health has been revealed in several previous reports. However, the results of studies regarding the association between AGEs and obesity measurements are inconsistent. In the current meta-analysis, we aimed to quantitatively summarize the results of studies that evaluated the association between circulating and dietary AGEs with obesity measurements among the adult population. Methods: A systematic search from PubMed, Embase, and Scopus electronic databases until 30 October 2022 retrieved a total of 21,429 observational studies. After duplicate removal, title/abstract screening, and full-text reading by two independent researchers, a final number of 18 manuscripts remained to be included in the meta-analysis. Results: Those in the highest category of circulating AGEs had ~1.5 kg/m2 reduced BMI compared with those in the lowest AGEs category [weighted mean difference (WMD): -1.485; CI: -2.459, -0.511; p = 0.003], while a nonsignificant increase in BMI was observed in the highest versus lowest category of dietary AGEs (WMD: 0.864, CI: -0.365, 2.094; p = 0.186). Also, lower amounts of circulating AGEs in individuals with obesity versus individuals without obesity were observed (WMD: -57.220, CI: -84.290, -30.149; p < 0.001). AGE type can be considered as a possible source of heterogeneity. Conclusion: In the current meta-analysis, we observed an inverse association between circulating AGEs and body mass index among adults. Due to low study numbers, further studies are warranted to better elucidate these results.

The impact of aerosol box on tracheal intubation during the COVID-19 pandemic: a systematic review.

INTRODUCTION: This study aimed to summarize the effect of the aerosol box on tracheal intubation in patients with COVID-19. AREAS COVERED: According to the PRISMA guidelines, a systematic search was performed to identify relevant literature on the 'impact of the aerosol box on tracheal intubation during the COVID-19 pandemic' in different electronic databases up to March 2021. Based on a set of predefined inclusion and exclusion criteria, 447 articles were screened. Finally, 20 articles were included in the current systematic review. The findings showed that the use of aerosol box during intubation could reduce droplet contamination on the healthcare workers but not necessarily aerosols. An increase in the time of intubation with the aerosol box was also observed in 9 out of 12 studies (75%); however, three studies reported no significant difference in the time of intubation with and without the aerosol box. Most studies (8 out of 9, 89%) were also shown that intubation with the aerosol box may lead to more difficulty. EXPERT OPINION: The proceduralist and other healthcare workers involved in airway management of COVID-19 infected patients should decide whether to apply the aerosol box with caution, balancing between benefits and risks, especially in difficult airway circumstances.

PCSK9 pathway-noncoding RNAs crosstalk: Emerging opportunities for novel therapeutic approaches in inflammatory atherosclerosis.

A variety of mechanisms contribute to the occurrence and development of inflammatory atherosclerosis (IA), resulting in cardiovascular disease. PCSK9 (proprotein convertase subtilisin/ kexin type 9) has now been recognized as a key player in the pathophysiology of atherosclerosis. Following PCSK9 activation, LDL receptors (LDLR) are degraded and as a result, LDL cholesterol (LDLC) levels are increased. Increasing evidence reports that the PCSK9 axis mediates IA through different pathways, such as LDLR, LOX1, NF-kB, and TLR4. In recent years, PCSK9 pathway dysregulation has been identified as one of the fundamental mechanisms involved in IA. Recently, the importance of epigenetic factors, in particular, in non-coding RNAs, including miRNAs and long ncRNAs (lncRNAs) as well as circular RNAs (circRNAs) in the regulation of physiological and pathological events has received great attention. In this regard, an expanding body of research has revealed that different ncRNAs play important roles in the progression of inflammatory atherosclerosis through targeting genes related to the PCSK9 pathway at the post-transcriptional level. Of importance, the current study aimed to review the relationship between the various ncRNAs and PCSK9 pathway to identify the molecular mechanisms underlying IA pathogenesis as well as to introduce the novel PCSK9 pathway-related therapeutic interventions in combating IA.

Recent Progress in Aptamer-Functionalized Metal-Organic Frameworks-Based Optical and Electrochemical Sensors for Detection of Mycotoxins.

Mycotoxin contamination in foodstuffs and agricultural products has posed a serious hazard to human health and raised international concern. The progress of cost-effective, facile, rapid and reliable analytical tools for mycotoxin determination is in urgent need. In this regard, the potential utility of metal-organic frameworks (MOFs) as a class of crystalline porous materials has sparked immense attention due to their large specific surface area, adjustable pore size, nanoscale framework structure and good chemical stability. The amalgamation of MOFs with high-affinity aptamers has resulted in the progress of advanced aptasensing methods for clinical and food/water safety diagnosis. Aptamers have many advantages over classical approaches as exceptional molecular recognition constituents for versatile bioassays tools. The excellent sensitivity and selectivity of the MOF-aptamer biocomposite nominate them as efficient lab-on-chip tools for portable, label-free, cost-effective and real-time screening of mycotoxins. Current breakthroughs in the concept, progress and biosensing applications of aptamer functionalized MOFs-derived electrochemical and optical sensors for mycotoxins have been discussed in this study. We first highlighted an overview part, which provides some insights into the functionalization mechanisms of MOFs with aptamers, offering a foundation to create MOFs-based aptasensors. Then, we discuss various strategies to design high-performance MOFs-based aptamer scaffolds, which serve as either signal nanoprobe carriers or signal nanoprobes and their applications. We perceived that applications of optical aptamers are in their infancy in comparison with electrochemical MOFs-derived aptasensors. Finally, current challenges and prospective trends of MOFs-aptamer sensors are discussed.

Intimate partner violence against pregnant women during the COVID-19 pandemic: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to estimate the pooled prevalence of (intimate partner violence) IPV against pregnant women in the COVID-19 pandemic. A literature search was conducted in PubMed, Web of Science, and Scopus for observational studies regarding the prevalence of IPV against pregnant women during the COVID-19 pandemic. The search was performed with the following keywords: intimate partner violence, domestic violence, battered women, wife assault, partner assault, wife abuse, partner abuse, femicide, domestic homicide, pregnancy, gestation, pregnant women, COVID-19, SARS-CoV-2, 2019-nCoV, Coronavirus Disease-19, 2019 Novel Coronavirus, Wuhan Coronavirus, SARS Coronavirus 2, Wuhan Seafood Market Pneumonia Virus. Heterogeneity between the studies was assessed using Cochran's Q test and I2 index. In addition, a random-effects model was used to estimate the prevalence of IPV. Data analysis was performed in Stata software version 16. Six articles met our inclusion criteria, which were conducted on 2213 pregnant women. The pooled prevalence of total IPV was estimated at 22 percent (95 percent Confidence Interval [CI]: 4-40 percent). Moreover, the pooled prevalence of psychological, physical, and sexual violence was reported to be 24 percent (95 percent CI: 13-35 percent), 14 percent (95 percent CI: 7-20 percent), and 6 percent (95 percent CI: 4-9 percent), respectively. Publication bias was significant (P = .01). According to the results, IPV against pregnant women has been relatively prevalent during the COVID-19 pandemic. Therefore, identifying the women who are at the risk of IPV is essential to preventing the consequences of maternal-fetal abuse and designing strategies to facilitate the reporting of violence during pandemics.

Considering the importance of SPR biosensors in the diagnosis of enocomarker CA 125, the main focus of the present study is to consolidate the research work from the past two decade to the present. Also, the advantages and challenges in SPR biosensors development have been considered in the detection of CA 125 oncomarker.

Current Progress in Aptasensor for Ultra-Low Level Monitoring of Parkinson's Disease Biomarkers.

In today's world, Parkinson's disease (PD) has been introduced as a long-term degenerative disorder of the central nervous system which mainly affects approximately more than ten million people worldwide. The vast majority of diagnostic methods for PD have operated based on conventional sensing platforms, while the traditional laboratory tests are not efficient for diagnosis of PD in the early stage due to symptoms of this common neurodegenerative syndrome starting slowly. The advent of the aptasensor has revolutionized the early-stage diagnosis of PD by measuring related biomarkers due to the myriad advantages of originating from aptamers which can be able to sensitive and selective capture various types of related biomarkers. The progress of numerous sensing platforms and methodologies in terms of biosensors based on aptamer application for PD diagnosis has revealed promising results. In this review, we present the latest developments in myriad types of aptasensors for the determination of related PD biomarkers. Working strategies, advantages and limitations of these sensing approaches are also mentioned, followed by prospects and challenges.
