Analysis Comparing the Recovery of Airway Reflexes and Cognitive Ability After Sevoflurane with Desflurane Anesthesia.

Introduction: Although sevoflurane and desflurane have nearly identical blood-gas solubilities, current research suggests that airway reflexes recover more quickly with desflurane than sevoflurane; however, cognitive function recovery varies substantially. The current study was piloted to appraise the lengths of time needed to recover from anesthesia following desflurane and sevoflurane anesthesia. Materials and Methods: A prospective clinical trial was piloted among 70 adult non-obese subjects who underwent elective surgery and were classified I-II by the "American Association of Anesthesiologists (ASA)". Sevoflurane and desflurane were tested among the subjects who were equally distributed. These agents were used in accordance with a normal general anaesthesia procedure. After they were extubated, tests for regaining cognitive function and airway reflexes were carried out, and different time intervals were recorded. The observations were calculated and P < 0.05 was used to conduct the statistical analysis. Results: The average amount of time that passed between the patient's first vocal response and their first successful completion of the swallowing test was analogous between the two groups (T2) with 5.25 ± 3.11 vs 5.01 ± 2.12 in sevoflurane and desflurane, respectively. There was no significant variance at T2. For all the other time intervals of T1, T3, and T4, there was evidence of the significant variance.(P = 0.003; 0.0013; <0.001, respectively). Conclusion: Desflurane causes patients to recover more quickly than sevoflurane does after laparoscopic cholecystectomy under controlled circumstances.

Knowledge and Perception about Health Risks of Cigarette Smoking among Youngsters in Jazan Region, Saudi Arabia.

Context: Cigarette smoking is a global public health concern, particularly in developing countries. Saudi Arabia has a high prevalence of smoking among young individuals, highlighting the need for interventions to address this issue. Aims: This study aimed to evaluate the awareness, attitude, smoking rates, and perception of health risks among young individuals in the Jazan region of Saudi Arabia. The goal was to identify areas for improvement and develop effective strategies to combat smoking and promote healthier lifestyles. Methods and Materials: A cross-sectional survey was conducted at the out-patient department of the College of Dentistry, Jazan University, over a 3-month period. A questionnaire consisting of 15 open-ended questions was administered to eligible patients. Statistical Analysis Used: Statistical analysis was performed using the Chi-squared test with a P- value of <0.05. Results: Out of 300 participants, the majority were males, university students, and non-smokers. Among smokers, electronic cigarettes were the most used form. Starting smoking with friends was a common trend. Females smoked fewer times per day compared to males. Participants expressed concerns about the damaging effects of smoking on health. Conclusions: Targeted interventions and educational programs are needed to address smoking behaviors among young individuals in the Jazan region. Gender-specific interventions, family involvement, and promoting school connectedness are crucial in reducing smoking rates. Graphic health warnings on cigarette packs have the potential to improve knowledge and quitting intentions. Continued research and surveillance are necessary to inform evidence-based policies and interventions to combat youth smoking.

Isolation Systems and its Effectiveness in Oral and Maxillofacial Surgery: A Systematic Review.

Introduction: The success of restoration processes depends on the efficient control of moisture and microorganisms. Dental restorative procedures frequently use rubber dams as an isolation technique. There is still room for evidence-based discussion over how rubber dam use affects the durability and caliber of dental restorations. In this review, the effects of rubber dam isolation vs alternative isolation techniques for dental restorative procedures are compared. Materials and Procedures: An extensive online search in the various databanks of the EMBASE, Medline, Pubmed, and Scopus was conducted. The keywords searched were "isolation, oral surgery, dental surgery, retractors, rubber dam, and methods of isolation." The studies selected were longitudinal research design and randomized trials. To ascertain the risk of bias, meta-analysis was carried out. The outcome was measured as the successful restoration at the end of follow-up period representing the thorough isolation. Results: A total of 1342 people were involved in six studies from across the world that were carried out between 2010 and 2015. High bias risk existed in all the studies. Five investigations compared the rubber dam vs cotton rolls. Due to discrepancies in the data supplied, one study was omitted from the analysis. Three of the four trials that were still running showed restored survival rates with all having a follow-up of at least six months. The survival of the restored composite teeth for six months in rubber dam isolation with odds ratio of 2.29, 1.38, and 1.00 at the end of six months, one year and one and half year respectively. However, the evidence was very low and speculative. The isolation was seen effective in the primary teeth specifically for the proximal lesions. None of the included studies discussed side effects or provided information on the treatment's upfront costs. Conclusion: The application of rubber dams in dental techniques may result in successful outcome compared to cotton rolls, according to some low-certainty evidence revealed in this research. Other times, the evidence is really ambiguous. It is necessary to conduct additional, high-quality studies investigating how rubber dam use affects various restorative procedures.

Control of post-harvest storage losses in water chestnut (Trapa bispinosa Roxburg) fruits by natural functional herbal coating and gamma radiation processing.

Water chestnut (Trapa bispinosa Roxburg) has short shelf life even after drying due to insect infestations resulting in huge economic losses to farmers. Study was performed including coating with Aloe-vera gel, air drying, LDPE packaging and gamma irradiation (≤ 1 kGy) were evaluated for their efficacy in controlling storage losses. The study was performed with complete randomized design up to 6-month storage period. Physico-chemical properties analysis indicated, weight loss (0.11-0.88%), damage (upto 6.5%) and lesser grain borer infestation (up to 16 no. per packet) during storage at different intervals. Moisture content ranged (9.25-10.10%), protein (8.82-8.89%), fat (0.90-1.00%), carbohydrate (76.83-76.89%), total ash (3.11-4.18%), total sugar (5.83-5.89%), reducing sugar (1.84-1.88%), non-reducing sugar (3.98-4.02%), amylose (66.54-66.64%), in-vitro starch digestibility (3.14-3.18%), phenolics (0.14-0.18%), acidity (0.11-0.12%) and ascorbic acid (41.66-50.00 mg/100 g). These treatments were not found to affect the quality attributes significantly however; it helps in controlling insect infestations at ambient condition. The sensory score of the product, 'Sev' was ranked as like slightly to moderately range. It could be concluded that water chestnut with combinations of 50% aloe-vera gel +0.75 kGy gamma radiation treatment could be stored up to 6 months with retention of quality attributes.

Malondialdehyde, an Oxidative Stress Marker in Oral Squamous Cell Carcinoma-A Systematic Review and Meta-Analysis.

OBJECTIVE: To qualitative and quantitatively review published literature assessing the oxidative stress marker malondialdehyde (MDA) in oral squamous cell carcinoma (OSCC). METHODOLOGY: Pubmed (MeSH), Science Direct, Scopus, Web of Science, Willey Online Library, Cochrane, and Cross Reference were searched for studies assessing MDA levels in OSCC samples. RESULTS: From the 1008 articles identified, 849 were excluded based on title and abstract screening due to duplication and irrelevance to the topic of interest. Full-text assessment of the remaining 159 articles led to the inclusion of only 46 articles that satisfied the selection criteria. Of these, only 26 studies had data compatible for quantitative analysis. The MDA levels in OSCC groups are significantly increased (p < 0.00001) in plasma, serum, and saliva samples in the majority of the studies evaluated. In contrast, MDA levels in OSCC tissue samples are significantly attenuated (p < 0.00001) compared to healthy controls, supported by fewer studies. CONCLUSIONS: The augmented MDA levels in plasma, serum, and saliva samples of the OSCC reflect the heightened oxidative stress level accurately. Further studies are required to understand the attenuated MDA levels in the tissue samples of OSCC. Correlation analysis between MDA levels with established clinicopathological prognostic markers could aid in formulating oxidative stress-based prognostication and treatment planning.

EGFR family and Src family kinase interactions: mechanics matters?

Receptor tyrosine kinases (RTKs), such as the EGF receptor family, and adhesion molecules, such as integrins, have historically been viewed to have distinctly separable roles in the cell. In this classical view, integrins mediate mechanical interactions between the cell and its surrounding extracellular matrix while RTKs handle signaling to modulate cellular behavior. Although crosstalk between these receptor pathways has been known to exist for a long time, this has generally been attributed to effects significantly downstream from the receptors themselves. In recent years, however, EGFR family RTKs have been found to directly participate in integrin-mediated force sensing, revealing a more complex interplay among these cellular components than originally appreciated. Here we briefly review the classical understanding of EGFR family RTK signaling and then provide a broadened perspective based on recent results.

Dynein Clusters into Lipid Microdomains on Phagosomes to Drive Rapid Transport toward Lysosomes.

Diverse cellular processes are driven by motor proteins that are recruited to and generate force on lipid membranes. Surprisingly little is known about how membranes control the force from motors and how this may impact specific cellular functions. Here, we show that dynein motors physically cluster into microdomains on the membrane of a phagosome as it matures inside cells. Such geometrical reorganization allows many dyneins within a cluster to generate cooperative force on a single microtubule. This results in rapid directed transport of the phagosome toward microtubule minus ends, likely promoting phagolysosome fusion and pathogen degradation. We show that lipophosphoglycan, the major molecule implicated in immune evasion of Leishmania donovani, inhibits phagosome motion by disrupting the clustering and therefore the cooperative force generation of dynein. These findings appear relevant to several pathogens that prevent phagosome-lysosome fusion by targeting lipid microdomains on phagosomes.
