Ovarian function can start to decline a few years before the eventual cessation of the menstrual cycle. The average age of menopause in the UK is 51 years, and it is a retrospective diagnosis after 12 months of amenorrhoea. Women can experience many symptoms such as vasomotor and vulvovaginal symptoms that impact them physically, psychologically, sexually and thus their overall wellbeing. Women may have medical contraindications to hormonal therapy or may prefer non-hormonal or alternative treatments. This review looks at the evidence, efficacy, and safety of a range of complementary or alternative treatments and non-hormonal pharmacological treatments for the treatment of vasomotor symptoms and vulvovaginal atrophy of menopause.Obstetric and gynaecology undergraduate training is an intense time for learners as they encounter various health conditions related to women's health and also learn about pregnancy care and birth. The experience is directed to familiarise students with basic clinical management of gynaecological conditions, also develop communication and related core examination and procedural skills. Similarly, midwifery training encompasses independent care of low-risk pregnant women and assist in care of high-risk pregnancy in partnership with obstetricians. Although its necessary to acquaint most learners with core clinical skills in obstetrics and gynaecology, learning opportunities on patients can be limited, due to the intrusive nature of women's health examination. Simulation Based Education (SBE) can facilitate learning hands-on clinical examination and procedural skills, using realistic part-task and high-fidelity simulators prior to approaching patients. This can apply to both medical and midwifery undergraduate training, further creating opportunities for professional interaction and shared learning space to facilitate interprofessional education. IPE has been shown to improve professional relationships in practicing clinicians. This learning pedagogy can be applied in the undergraduate setting as well, to decrease risk of conflict and appreciate roles of other interprofessional staff in future clinical practice. In this chapter we highlight some challenges faced by medical and midwifery undergraduates in their learning from a global perspective. We also describe some teaching and learning initiatives that can be applicable across various settings of obstetrics, gynaecology medical undergraduate and midwifery teaching with relevant case studies to facilitate new graduates preparedness for practice.Surgery is the best option for patients with early stage non-small cell lung cancer (NSCLC). However, the rate of local and metastatic recurrences following surgery alone is high, especially in NSCLC patients with N2 lymph node involvement. A recent American study showed that 60% of lung cancers are diagnosed in an advanced stage, and less than 20% are diagnosed in an early, resectable stage. The same study reported the 5 year survival of patients with stage IV NSCLC was 6% compared to 50% in patients with resectable NSCLC depending by stage. The addition of adjuvant or neoadjuvant chemotherapy only improves 5 year survival by 5%-10%. Recently, immunotherapy with or without chemotherapy and novel targeted therapies have yielded excellent results, in terms of both progression-free survival and overall survival, in advanced NSCLC. Published studies have shown a benefit in using immunotherapy and targeted therapy in both the adjuvant and neoadjuvant settings with many further studies still ongoing. Here we review the published data on immunotherapy and targeted therapy in the adjuvant and neoadjuvant settings in patients with operable NSCLC.Prostate cancer (CaP) is the most common malignant neoplasm of the urinary tract. The current recommendations for CaP diagnosis rely on the prostate-specific antigen levels and a digital rectal examination for anatomical abnormalities. However, these diagnostic tools are not highly sensitive. In particular, prostate-specific antigen has a low positive predictive value (approximately 30%). Thus, there is a need to develop biomarkers to improve the early clinical detection of CaP. Several novel technologies enable the identification of biomarkers from diverse sources, including the urine, serum, and prostate tissues. Furthermore, advances in genomic techniques have enabled the analysis of novel biomarkers, such as deoxyribonucleic acids (DNAs), ribonucleic acids (RNAs), proteins, and circulating tumor cells. Previous studies have demonstrated that RNAs are potential diagnostic biomarkers for various cancers using high-throughput sequencing analysis. The sensitivity and specificity of RNA biomarkers are higher than those of protein biomarkers. Polymerase chain reaction enables the amplification of trace levels of RNAs with high sensitivity and specificity. RNA biomarkers provide dynamic insights into cellular states and regulatory processes when compared with DNA biomarkers. Additionally, multiple copies of various RNAs in a cell provide more information than DNA. The levels of specific RNAs in CaP tissues are upregulated when compared with those in non-cancerous tissues. Additionally, RNAs can be easily isolated from various body fluids. see more Thus, RNAs are potential non-invasive biomarkers for CaP. Moreover, the analysis of RNA levels adjusted for each stage of CaP enables the determination of prognostic individualized therapy for aggressive or progressive CaP. This review focused on the diagnostic and prognostic values of RNAs for CaP.The interaction between mechanical loading and energy availability on bone health in male endurance athletes merits further investigation. The purpose of this study was to compare bone status in male competitive runners and road cyclists and to investigate the influence of energy availability (EA) on bone mineral density (BMD). 18 competitive runners and 19 road cyclists (20-50 years) participated in this study. Areal BMD and body composition were assessed by dual energy x-ray absorptiometry. Volumetric bone variables at the 4% and 66% tibia sites were assessed by peripheral quantitative computed tomography. Energy availability (EA, 7-day dietary and exercise logs) and resting metabolic rate (RMR, open circuit spirometry) were measured as indicators of energy status. Bone loading history, calcium intake, and training history were assessed by questionnaires. After adjusting for age, runners had significantly greater (p less then 0.05) areal BMD (femoral neck, left total hip), Z-scores (total body, hips sites), total bone mineral content and trabecular variables (bone mineral content, volumetric BMD, bone strength index) at tibia 4% site, and total volumetric BMD at tibia 66% site than the cyclists (p ≤ 0.05). At the tibia 66% site, cyclists had significantly greater (p less then 0.05) total area, periosteal circumference, endosteal circumference, and strength-strain index than runners. Energy variables were similar for runners and cyclists; however, RMR and RMR ratio (measured RMR/predicted RMR) were significantly lower in cyclists (p less then 0.001). In conclusion, there were site-specific differences in hip and tibia bone characteristics between runners and cyclists. RMR was associated with several bone outcomes; however, EA was not related to bone health in runners or to dual energy x-ray absorptiometry bone variables in cyclists.mRNAs translation to proteins constitutes an important step of cellular gene expression that is highly regulated in response to different extracellular stimuli and stress situations. The fine control of protein synthesis is carried out both qualitatively and quantitatively, depending on the cellular demand at each moment. Post-translational modifications, in turn regulated by intracellular signaling pathways, play a key role in translation regulation. Among them, ubiquitination, whose role is becoming increasingly important in the control of translation, determines a correct balance between protein synthesis and degradation. In this review we focus on the role of ubiquitination (both degradative K48-linkage type and non-degradative K63-linkage type and monoubiquitination) in eukaryotic translation, both at the pre-translational level during the biogenesis/degradation of the components of translational machinery as well as at the co-translational level under stressful conditions. We also discuss other ubiquitin-dependent regulatory mechanisms of mRNA protection and resumption of translation after stress removal, where the ubiquitination of ribosomal proteins and associated regulatory proteins play an important role in the global rhythm of translation.Kojic acid (KA) is a representative secondary metabolite of Aspergillus oryzae, but the underlying molecular mechanisms that regulate KA production are unknown. This study tried to find a genetic factor of KA production in A. oryzae, with a special focus on liquid cultures. We screened a gene predicted to encode HirA, a subunit of the histone chaperon, the HIR complex. A gene disruption strain of hirA showed decreased KA production in liquid culture, whereas it showed increased KA production in plate culture. We confirmed that a decrease/increase of KA production observed by hirA disruption was caused by altered expression of kojA and kojR. These observations suggested the regulatory role of histone chaperon in secondary metabolism in filamentous fungi. So far as we know, this report is the first showing that disruption of a gene resulted in the opposite effect on KA production in liquid and plate cultures in A. oryzae.Euglena gracilis, a phototrophic protist, is a valuable biomass producer that is often employed in sustainable development efforts. E. gracilis accumulates wax esters as byproducts during anaerobic ATP production via the reductive tricarboxylic acid cycle, utilizing the storage carbohydrate β-1,3-glucan paramylon as the carbon source. Here, we report a library screening for chemical stimulators that accelerate both wax ester production and paramylon consumption. Among the 115 compounds tested, we identified nine compounds that increased wax ester production by more than 2.0-fold relative to the solvent control. In the presence of these nine compounds, the paramylon content decreased compared with the control experiment, and the residual paramylon content varied between 7% and 26% of the initial level. The most active compound, 1,4-diaminoanthracene-9,10-dione (OATQ008), stimulated wax ester production up to 2.7-fold within 24 h, and 93% of the cellular paramylon was consumed. In terms of the structural features of the chemical stimulators, we discuss the potential target sites to stimulate wax ester production in mitochondria under anaerobic conditions.Our body is central to our sense of self, and distorted body representations are found in several serious medical conditions. This paper reviews evidence that distortions of body representations are also common in healthy individuals, and occur in domains including tactile spatial perception, proprioception, and the conscious body image. Across domains, there is a general tendency for body width to be overestimated compared to body length. Intriguingly, distortions in both eating disorders and chronic pain appear to be exaggerations of this baseline pattern of distortions, suggesting that these conditions may relate to dysfunction of mechanisms for body perception. Distortions of body representations provide a revealing window into basic aspects of self-perception.
