Prevalence and Risk Factors of Voice Disorders in University Teaching Faculty Members: A Pilot Study
Voice disorder is a multifactorial impairment. Several studies have shown that there is a direct relationship between voice problems and voice-related jobs. Therefore, professional voice users, including teachers, are at high risk of voice disorders, which threatens the employment positions. Also, the investigation of voice impairments among faculty members seems essential. The purpose of this study is to assess the prevalence of voice disorders in faculty members, its impact on the physical, emotional, and functional status of this job group, with and without voice disorders, and the correlation of voice disorders with some risk factors. Methods The participants of this study were 114 university teaching faculty members of Mashhad University of Medical Sciences, with a mean age of 43.95±0.98 years. The current cross-sectional descriptive-analytical study used a demographic questionnaire and Voice Handicap Index (VHI) as the data collection instruments. In the present study, based on VHI test results, participants with a total VHI score greater than 14.5 are considered to have voice disorders. Results The prevalence of voice disorders among university teaching faculty members was 27.19%. There was a significant correlation between allergy and voice disorders (P= 0.04). Significant differences were also found between the two study groups in terms of the total score of the VHI and its subscales (P <0.001). Conclusions Considering the 27.19% prevalence of voice disorders among university teaching faculty members and its effect on the total VHI score, our results confirm that education, prevention, and treatment programs are critical to lessen the frequency of voice disorders related to teaching. However, it has been found that this job group with voice disorders is four times more likely to have allergies than those without voice disorder, which indicates the importance of controlling this problem

Hippo-YAP/TAZ signaling in breast cancer: Reciprocal regulation of microRNAs and implications in precision medicine
Breast cancer is a molecularly heterogeneous disease and the most common female malignancy. In recent years, therapy approaches have evolved to accommodate molecular diversity, with a focus on more biologically based therapies to minimize negative consequences. To regulate cell fate in human breast cells, the Hippo signaling pathway has been associated with the alpha subtype of estrogen receptors. This pathway regulates tissue size, regeneration, and healing, as well as the survival of tissue-specific stem cells, proliferation, and apoptosis in a variety of organs, allowing for cell differentiation. Hippo signaling is mediated by the kinases MST1, MST2, LATS1, and LATS2, as well as the adaptor proteins SAV1 and MOB. These kinases phosphorylate the downstream effectors of the Hippo pathway, yes-associated protein (YAP), and transcriptional coactivator with PDZ-binding motif (TAZ), suppressing the expression of their downstream target genes. The Hippo signaling pathway kinase cascade plays a significant role in all cancers. Understanding the principles of this kinase cascade would prevent the occurrence of breast cancer. In recent years, small noncoding RNAs, or microRNAs, have been implicated in the development of several malignancies, including breast cancer. The interconnections between miRNAs and Hippo signaling pathway core proteins in the breast, on the other hand, remain poorly understood. In this review, we focused on highlighting the Hippo signaling system, its key parts, its importance in breast cancer, and its regulation by miRNAs and other related pathways
Protective effect of co-enzyme Q10 on testicular tissue and sperm parameters in adult male rats treated with Sunset Yellow FCF
Objective: To determine the protective effect of co-enzyme Q10 (CoQ10) on testicular tissue and sperm parameters in male rats treated with Sunset Yellow FCF.
Methods: Sixty male Sprague-Dawley rats were randomly divided into 6 groups of the control, CoQ10 (10 mg/kg/day), low dose of Sunset Yellow (2.5 mg/kg), high dose of Sunset Yellow (70 mg/kg), low dose of Sunset Yellow (2.5 mg/kg) plus CoQ10, and high dose of Sunset Yellow (70 mg/kg) plus CoQ10. The drugs were administered via daily oral gavages for 6 weeks. At the end of the experiment, sperm analysis, stereological and histological assessments of the testis were carried out.
Results: The normal morphology (by 41.1%) and progressive spermatozoa (by 74.8%), testicle volume (by 33.4%), lumen volume (by 38.3%), interstitial tissue volume (by 44.7%), seminiferous tubule volume (by 40.7%), and number of spermatogonia (by 53.9%) and Leydig cells (by 70.7%) reduced in the rats that received high doses of Sunset Yellow in comparison to the control group. Nonetheless, all these alterations were recovered by CoQ10 treatment in the CoQ10 plus high dose of Sunset Yellow group. Furthermore, low doses of Sunset Yellow did not affect different parameters of the testis and sperm.
Conclusions: CoQ10 could, to some extent, prevent structural changes of the testis induced by the high dose of Sunset Yellow
Preparation and Characterization of Maltodextrin Microcapsules Containing Walnut Green Husk Extract
In recent years, the field of natural antimicrobial and antioxidant compounds is one of the main research topics in the food industry. Application of agricultural residues is mainly cheap, and available resources are receiving increased attention. Walnut green husk is one of the agricultural residues that is considered as natural compounds with biological properties because of phenolic compounds. In this study, maltodextrin 10% was used for microencapsulation of walnut green husk extract. At first, the extract was examined to consider extraction yield, total phenolic compounds, and antioxidant activation. The results showed the extraction yield of 81.43%, total phenolic compounds of 3997 [mg GAE/100 g], antioxidant activity [DPPH] of 84.85% for walnut green husk extract. Antioxidant activity is about 75%-81% and by DPPH. At the next stage, microencapsulation was done by spry-drying method. The microencapsulation efficiency was 72%-79%. The results of SEM tests confirmed this microencapsulation process. In addition, microencapsulated and free extract was more effective on gram-positive bacteria’s rather than the gram-negative ones. According to the study, walnut green husk can be used as a cheap antioxidant and antimicrobial compounds due to sufficient value of phenolic compounds
Pulmonary fibrosis: Therapeutic and mechanistic insights into the role of phytochemicals
Pulmonary fibrosis (PF) is the devastating consequence of various inflammatory diseases of the lung. PF leads to a reduction of lung function, respiratory failure, and death. Several molecular pathways are involved in PF, such as inflammatory cytokines including tumor necrosis factor α (TNFα), tumor necrosis factor β1 (TNFβ1), interleukin 6 (IL-6), and interleukin 4 (IL-4), reactive oxygen species, matrix metalloproteases, and transforming growth factor-beta (TGF-β). Targeting these processes involved in the progression of PF is essential for the treatment of this disease. Natural products, including plant extracts and active compound that directly target the processes involved in PF, could be suitable therapeutic options with less adverse effects. In the present study, we reviewed the protective effects and the therapeutic role of various bioactive compounds from plants in PF management
The importance of hsa-miR-28 in human malignancies
MicroRNA production in tumorigenesis is dysregulated by a variety of processes, such as proliferation and removal of microRNA genes, aberrant transcriptional regulation of microRNAs, disrupted epigenetic alterations, and failures in the miRNA biogenesis machinery. Under some circumstances, miRNAs may act as tumorigenic and maybe anti-oncogenes. Tumor aspects such as maintaining proliferating signals, bypassing development suppressors, delaying apoptosis, stimulating metastasis and invasion, and promoting angiogenesis have been linked to dysfunctional and dysregulated miRNAs. MiRNAs have been found as possible biomarkers for human cancer in a great deal of research, which requires additional evaluation and confirmation. It is known that hsa-miR-28 can function as an oncogene or tumor suppressor in many malignancies, and it does this by modulating the expression of several genes and the downstream signaling network. MiR-28–5p and miR-28–3p, which originate from the same RNA hairpin precursor miR-28, have essential roles in a variety of cancers. This review outlines the function and mechanisms of miR-28–3p and miR-28–5p in human cancers and illustrates the miR-28 family's potential utility as a diagnostic biomarker for prognosis and early detection of cancers
