Despite the belief about the persistence of HPV infection in older than 30-year-old women, high-grade lesions might be detected in younger ages; therefore, the purpose of the current study is to determine the worth of HPV infection screening in younger than 30-year-old women.Materials and methods: This cross-sectional study has been executed on 100 under 30-year-old women who have undergone genotyping. Fourteen HPV subtypes including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68 were defined as high risk and the patients were categorized in HPV 16/18 or other high-risk groups. Pap smear and colposcopy were performed for both groups and interpreted as normal, low-risk and high-risk lesions and compared between the groups.Results: In terms of demographic, clinical, and sexual behavioral characteristics, the present study exhibited similarity (P value > 0.05). Pap smear (P value = 0.100) and colposcopy (P value = 0.711) grading did not differ between those with HPV 16/18 versus other high-risk HPV patients. Pap smear and colposcopic findings were weekly in agreement (κ < 0.5, P value < 0.001).Conclusion: Early cytological plus genotyping assessment in women at early child-bearing ages seems logical, as the cervical premalignant lesions have a slow progressing nature and can be easily treated in early stages.","PeriodicalId":94292,"journal":{"name":"Advanced biomedical research","volume":"13 ","pages":"119"},"PeriodicalIF":0.7,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11850943/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143506742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effect of adding dexmedetomidine as an adjuvant to bupivacaine for postoperative pain management.Materials and methods: This double-blind, randomized clinical trial was performed on 80 patients aged 20 to 60 with ASA I and II who were candidates for elective shoulder rotator cuff repair. Forty candidates in the control group received 0.1% bupivacaine intra-articular and extra-articular before surgical wound closure, and 40 patients in the intervention group received 0.1% bupivacaine and dexmedetomidine 1 µg/kg intra-articular and extra-articular. Postoperative sleep disturbance and pain intensity were measured at recovery, 4, 8, 12, 18, and 24 hours after surgery. The results were analyzed by SPSS software version 23, and a P value ≤0.05 was considered significant.Results: There were no significant differences between the two groups regarding the hemodynamic variations (P > 0.05), except 4 hours after surgery when the mean arterial pressure in the intervention group was significantly lower than the control group (P = 0.026). There was a significant reduction in pain scores at 8 and 12 hours after surgery in the intervention group. The night after surgery, sleep quality and the overall RCSQ score in the intervention group were significantly higher than those in the control group.Conclusion: Administering 0.1% bupivacaine and dexmedetomidine 1 µg/kg intra-articular and extra-articular before surgical wound closure effectively reduced the pain intensity and analgesic consumption.

This study evaluated the effects of Lucilia sericata (L. sericata) larvae and Eisenia fetida (E. fetida) earthworm extracts, alone or in combination, on the healing of third-degree burns in male mice.Materials and methods: A third-degree burn model was induced on the skin of the interscapular region. Then, the extracts of larvae and earthworms were topically applied separately or simultaneously every other day for a 21-day period. To evaluate the process of wound healing, macroscopic parameters were monitored and examined during the study period. Finally, the animals were sacrificed, and skin sampling was performed for histological investigations.Results: The results of the study showed that both extracts of larvae and earthworm accelerated the wound-healing process (P < 0.01). The group receiving extract of earthworm had better wound healing than the groups receiving Vaseline and silver sulfadiazine, and histological evidences confirmed these observations. However, the use of two extracts simultaneously did not affect the wound-healing process.Conclusion: The results of this study demonstrated that the extracts of L. sericata larvae and E. fetida earthworm, especially E. fetida, include effective compounds that can significantly enhance the rate of burn wound healing.

Chemotherapy is the primary treatment, but some patients use herbal remedies, such as Peiminine from Fritillaria walujewii, for palliative care. Cancer cells can affect the expression of noncoding RNAs, like microRNA, which can then influence the expression of genes. This research aims to study the effects of Peiminine on Doxorubicin cytotoxicity and detect the expression levels of hsa-miR-106a-5p and hsa-miR-181a-5p in AGS human gastric adenocarcinoma cells.Materials and methods: AGS cells were cultured and treated with different concentrations of Peiminine. An MTT assay was performed to determine the concentration of Peiminine required to prohibit 50% cell growth (IC50) and the cell viability percentage of the AGS cell line. The percentage of AGS cell line apoptosis was determined using acridine orange (AO) and ethidium bromide (EtBr). Finally, molecular studies were conducted to compare hsa-miR-106a-5p and hsa-miR-181a-5p expression in the control and treated groups.Results: According to the study, Peiminine has been found to enhance the cytotoxicity of Doxorubicin, which reduces cell viability and increases apoptosis in the AGS cell line. Furthermore, the study also indicates that the AGS cell line treated with Peiminine shows lower expression of hsa -miR-106a-5p and hsa -miR-181a-5p compared to the control group that was not treated.Conclusion: Peiminine enhances Doxorubicin's effectiveness, inhibits AGS cell line growth, and reduces miRNA expression.

In recent years, NPs have been used as antibiotics to overcome drug resistance or as drug carriers with antimicrobial features. They can also serve as antimicrobial coatings for implants in different body areas. The antimicrobial feature of NPs is based on different mechanisms. For example, the oxidative functions of NPs can inhibit nucleic acid replication and destroy the microbial cell membrane as well as interfere with their cellular functions and biochemical cycles. On the other hand, NPs can disrupt the pathogens' lifecycle by interrupting vital points of their life, such as virus uncoating and entry into human cells. Many types of NPs have been tested by different scientists for these purposes. Silver, gold, copper, and titanium have shown the most ability to inhibit and remove pathogens inside and outside the body.

Notably, this severity was predominantly observed in two male patients with Bruton's disease (BD) and one female patient with autosomal recessive hypogammaglobinemia. Moderate and severe COVID-19 cases were equally distributed (13.33%). In the female subgroup, one patient with common variable immunodeficiency and another with combined immunodeficiency experienced moderate and severe COVID-19, respectively. Conversely, both male patients with moderate and severe COVID-19 had BD.Conclusion: Despite the limited number of severe cases, the absence of cytokine storm manifestation suggests potential protective mechanisms, possibly due to intravenous immunoglobulin therapy and inherent deficiencies within cytokine-producing cells (B and T cells). While IEIs may not be significant risk factors for COVID-19, they offer promising avenues for further research into therapeutic strategies targeting specific immune system components to mitigate severe COVID-19.","PeriodicalId":94292,"journal":{"name":"Advanced biomedical research","volume":"13 ","pages":"112"},"PeriodicalIF":0.7,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11665184/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142883429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
