RESUMO

Aim: To explore the perception and lay understanding of sexual intercourse and sexual life experiences among infertile couples before, during, and after undergoing an assisted reproduction technology (ART) program. Method: The participants of this descriptive qualitative study were Indonesian couples with infertility who underwent an ART program. Semi-structured interviews were conducted between September and December 2022, and the participants' responses were recorded. Data were analyzed using a step-by-step analysis based on Braun's qualitative analysis. The study was reported based on the Consolidated Criteria for Reporting a Qualitative Research (COREQ) Checklist. Results: Fifty participants were included, and five themes were developed before and two themes during or after the ART program. The couples' knowledge varied as they experienced sexual intercourse at different periods, such as before, during, and after the ART program. Many participants reported that ART affected their emotions and mood, leading to decreased desire to engage in sexual intercourse. However, some used sexual intercourse as a basis for creating optimism and confidence in having offspring. Furthermore, couples perceived that the purpose of sexual intercourse is not only to have offspring but also to improve communication, promote intimacy, and express affection. In contrast, some perceived the ART program as time consuming, preventing them from engaging in sexual activities. However, not all couples considered sexual activity solely as a means of procreation. They concluded that sexual behavior is not only determined by genetics. Conclusion: Couples who underwent the ART program regardless of its effectiveness were aware that sexual interaction is not only for having children but also for preserving harmony and familial connection.

RESUMO

Shortening the aging duration and enhancing the functional components of garlic present significant technical challenges that need to be addressed. Thus, this study aimed to evaluate the potential role of pulsed electric field (PEF) treatment, a novel nonthermal food processing method, in promoting and enhancing the functional attributes of aged garlic. Our results showed that 2-4 kV/cm PEF pretreatment increased S-allyl cysteine (SAC), total polyphenol (TPC), and flavonoid contents (TFC) compared with un-pretreated garlic during aging. The browning and texture-softening were also significantly improved during processing time, though the latter showed no significant difference from the eighth day to the end of the aging process. The principal component analysis results showed that PEF positively affects the SAC and TFC formations without adverse effects. Among the PEF pretreatments, 3 kV/cm is the most effective in enhancing functional component production compared with the other PEF pretreatments. Therefore, PEF pretreatment is a time-saving process that promotes and enhances the functionality of aged garlic.

RESUMO

Background: Traditional Chinese Medicine (TCM), has been used for hepatocellular carcinoma (HCC) at every therapeutic stage, even before tumor formation. However, the efficacy of TCM in reducing the incidence of HCC in patients with chronic hepatitis B-related cirrhosis remains unclear. This study aims to address this gap. Methods: Publications were collected from PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, Sino Med, VIP, and Wan Fang Databases. Relative risk (RR) was calculated with a 95 % confidence interval (CI). Heterogeneity was assessed. The Cochrane Collaboration's tool was used to assess the risk of bias. Results: 10 studies with 2702 patients showed that the combination therapy significantly reduced the incidence of HCC in patients with post-hepatitis B cirrhosis at 1, 3, and 5 years. However, the preventive effects of TCM were in compensated cirrhosis, but not the decompensated cirrhosis. Furthermore, TCM correlated with improved liver function and enhanced virological response. Conclusion: Combination therapy with TCM demonstrated the certain potential in reducing the incidence of HCC in patients with hepatitis B cirrhosis. This is attrinuted to the improvement of liver function and enhancement of the viral response. However, the efficacy of TCM in the field still needs more high-quality RCTs to provide stronger evidence in the future.

RESUMO

The biochemical SRX (super-relaxed) state of myosin has been defined as a low ATPase activity state. This state can conserve energy when the myosin is not recruited for muscle contraction. The SRX state has been correlated with a structurally defined ordered (versus disordered) state of muscle thick filaments. The two states may be linked via a common interacting head motif (IHM) where the two heads of heavy meromyosin (HMM), or myosin, fold back onto each other and form additional contacts with S2 and the thick filament. Experimental observations of the SRX, IHM, and the ordered form of thick filaments, however, do not always agree, and result in a series of unresolved paradoxes. To address these paradoxes, we have reexamined the biochemical measurements of the SRX state for porcine cardiac HMM. In our hands, the commonly employed mantATP displacement assay was unable to quantify the population of the SRX state with all data fitting very well by a single exponential. We further show that mavacamten inhibits the basal ATPases of both porcine ventricle HMM and S1 (Ki, 0.32 and 1.76 µM respectively) while dATP activates HMM cooperatively without any evidence of an SRX state. A combination of our experimental observations and theories suggests that the displacement of mantATP in purified proteins is not a reliable assay to quantify the SRX population. This means that while the structurally defined IHM and ordered thick filaments clearly exist, great care must be employed when using the mantATP displacement assay.
