The Effect of Cervical Cancer and Human Papillomavirus Vaccine Education on Vaccination Perception in University Students: A Quasi-Experimental Controlled Educational Intervention.

The study investigated the impact of cervical cancer and human papillomavirus (HPV) vaccine education on university students' vaccination perceptions. This research was conducted with pre- posttest and quasi-experimental design with students enrolled in the department of health services of a university. The sample of the study consisted of 87 students ( = 43 in the intervention group, = 44 in the control group).

Comparison of bacteriological culture method and multiplex real-time PCR for detection of mastitis.

This study includes the evaluation of multiplex real-time PCR (rPCR) kit, which was developed to provide rapid diagnosis of mastitis infections, by working with milk samples of 2 different sources of mastitis and comparing the results with the classical bacteriological culture method (BC). A total of 273 bacteria were isolated in 226 samples (47.88%) out of 472 samples by BC.

Listening effort, fatigue, and streamed voice quality during online university courses.

Understanding the impact of listening effort (LE) and fatigue has become increasingly crucial in optimizing the learning experience with the growing prevalence of online classrooms as a mode of instruction. The purpose of this study was to investigate the LE, fatigue, and voice quality experienced by students during online and face-to-face class sessions. A total of 110 participants with an average age of 20.

Phenotypic evaluation of mast cells in bovine mammary tissue and mastitis in the context of fibrosis.

This research paper addresses the hypothesis that mast cells (MCs) contribute to the formation of mammary fibrosis. MCs are important immune regulatory and immune modulatory cells that play major roles in the inflammatory process. Since there is no detailed knowledge, this research study aimed to comparatively investigate the presence, localization, and immunophenotypes of MCs in healthy and mastitic mammary tissues.

Comparison of Participation in Online Games and Communication Experiences of School-Age Children Who Do and Do Not Stutter: Exploratory Study.

Introduction: Online games provide a socializing environment for children aged 8-10 years, but there is a lack of information in the literature about whether children who stutter (CWS) access online gaming environments as frequently as their nonaffected peers and about their interaction habits. This study aimed to investigate the participation frequency of school-age CWS and children who do not stutter (CWNS) in online games, the speech characteristics during games, and whether they encountered bullying-like behaviors during games.

Methods: A total of 91 CWS (F/M = 18/73; age range = 8-13) and 116 CWNS (F/M = 60/56; age range 8-13) participated in this study.

Localized glucose import, glycolytic processing, and mitochondria generate a focused ATP burst to power basement-membrane invasion.

Invasive cells use transient, energy-consuming protrusions to breach basement membrane (BM) barriers. Using the ATP sensor PercevalHR during anchor cell (AC) invasion in Caenorhabditis elegans, we show that BM invasion is accompanied by an ATP burst from mitochondria at the invasive front. RNAi screening and visualization of a glucose biosensor identified two glucose transporters, FGT-1 and FGT-2, which bathe invasive front mitochondria with glucose and facilitate the ATP burst to form protrusions.

Label-Free Imaging of Lipid Storage Dynamics in Caenorhabditis elegans using Stimulated Raman Scattering Microscopy.

Lipid metabolism is a fundamental physiological process necessary for cellular and organism health. Dysregulation of lipid metabolism often elicits obesity and many associated diseases including cardiovascular disorders, type II diabetes, and cancer. To advance the current understanding of lipid metabolic regulation, quantitative methods to precisely measure in vivo lipid storage levels in time and space have become increasingly important and useful.

Lipid metabolism and lipid signals in aging and longevity.

Lipids play crucial roles in regulating aging and longevity. In the past few decades, a series of genetic pathways have been discovered to regulate lifespan in model organisms. Interestingly, many of these regulatory pathways are linked to lipid metabolism and lipid signaling.

Olfactory specificity regulates lipid metabolism through neuroendocrine signaling in Caenorhabditis elegans.

Olfactory and metabolic dysfunctions are intertwined phenomena associated with obesity and neurodegenerative diseases; yet how mechanistically olfaction regulates metabolic homeostasis remains unclear. Specificity of olfactory perception integrates diverse environmental odors and olfactory neurons expressing different receptors. Here, we report that specific but not all olfactory neurons actively regulate fat metabolism without affecting eating behaviors in Caenorhabditis elegans, and identified specific odors that reduce fat mobilization via inhibiting these neurons.

Fingerprint Stimulated Raman Scattering Imaging Reveals Retinoid Coupling Lipid Metabolism and Survival.

Retinoids play critical roles in development, immunity, and lipid metabolism, and their deficiency leads to various human disorders. Yet, tools for sensing retinoids in vivo are lacking, which limits the understanding of retinoid distribution, dynamics and functions in living organisms. Here, using hyperspectral stimulated Raman scattering microscopy, we discover a previously unknown cytoplasmic store of retinoids in Caenorahbditis elegans.

High-throughput screens using photo-highlighting discover BMP signaling in mitochondrial lipid oxidation.

High-throughput screens at microscopic resolution can uncover molecular mechanisms of cellular dynamics, but remain technically challenging in live multicellular organisms. Here we present a genetic screening method using photo-highlighting for candidate selection on microscopes. We apply this method to stimulated Raman scattering (SRS) microscopy and systematically identify 57 Caenorhabditis elegans mutants with altered lipid distribution.

Olfaction Modulates Reproductive Plasticity through Neuroendocrine Signaling in Caenorhabditis elegans.

Reproductive plasticity describes the ability of organisms to adjust parameters such as volume, rate, or timing of progeny production in order to maximize successful reproduction under different environmental conditions. Reproductive plasticity in response to environmental variation has been observed in a wide range of animals; however, the mechanisms involved in translating environmental cues into reproductive outcomes remain unknown. Here, we show that olfaction modulates reproductive timing and senescence through neuroendocrine signaling in Caenorhabditis elegans.

Label-free biomedical imaging of lipids by stimulated Raman scattering microscopy.

Advances in modern optical microscopy have provided unparalleled tools to study intracellular structure and function, yet visualizing lipid molecules within a cell remains challenging. Stimulated Raman Scattering (SRS) microscopy is a recently developed imaging modality that addresses this challenge. By selectively imaging the vibration of chemical moieties enriched in lipids, this technique allows for rapid imaging of lipid molecules in vivo without the need for perturbative extrinsic labels.

The effects of a wheat germ rich diet on oxidative mtDNA damage, mtDNA copy number and antioxidant enzyme activities in aging Drosophila.

The free radical theory of aging posits that the accumulation of macromolecular damage induced by toxic reactive oxygen species plays a central role in the aging process. Therefore consumption of dietary antioxidants appears to be of great importance. Wheat germ have strong antioxidant properties.

Increase in mitochondrial DNA copy number in response to ochratoxin A and methanol-induced mitochondrial DNA damage in Drosophila.

The current study examined the effects of ochratoxin A (OTA) and methanol on mitochondrial DNA (mtDNA). The results showed that methanol application caused approximately 29 % more damage than the control group, and that there were no significant differences among the other groups in terms of mtDNA damage. The application of 0.
