[Association between dietary fat intake and risk of polycystic ovary syndrome].

Objective: To analyze the association between dietary fat intake and the risk of polycystic ovarian syndrome(PCOS).

Methods: PCOS patients treated in a tertiary hospital in Anhui Province from October 2021 to October 2022 were selected as the case group, and non-PCOS patients treated in the hospital during the same period were selected as the control group. A total of 262 subjects were included in the study, 131 were included in the case group and 131 in the control group.

Serum Cu, Zn and IL-1β Levels May Predict Fetal Miscarriage Risk After IVF Cycles: A Nested Case-Control Study.

To explore the association between serum-related indicators (levels of inflammatory cytokines and essential trace elements) and miscarriage risk among infertile women undergoing assisted reproductive techniques (ART) on the 14th day after embryo transfer, and to develop and establish a multivariable algorithm model that might predict pregnancy outcome. According to a nested case-control study design, a total of 100 miscarriage cases and 100 live birth controls were included in this study, and women in both groups were infertile and have underwent in vitro fertilization (IVF). Pregnancy tests were performed and serum levels of five essential trace elements (vanadium (V), copper (Cu), zinc (Zn), selenium (Se) and molybdenum (Mo)) and five inflammatory cytokines (interleukin-1β (IL-1β), IL-6, IL-8, IL-10 and tumor necrosis factor-α (TNF-α)) of the participants were measured on the 14th day after embryo transfer.

Resilience of infertile families undergoing in vitro fertilization: An application of the double ABC-X model.

Background: Family resilience plays a crucial role in protecting the mental health and family stability of infertile patients. However, information associated with infertile families resilience is scarce. The double ABC-X model provides a roadmap for this, helps organize knowledge, and lays the foundation for knowledge development.

Algicidal characteristics of novel algicidal compounds, cyclic lipopeptide surfactins from s strain D8, in eliminating blooms.

blooms have caused severe damage to marine ecosystems, the aquaculture industry and human health worldwide. In this study, D8 isolated from an bloom area was found to exert high algicidal activity extracellular metabolite production. This activity remained stable after exposure to different temperatures and light intensities.

Sexual Function, Self-Esteem, and Quality of Life in Infertile Couples Undergoing in vitro Fertilization: A Dyadic Approach.

Purpose: Infertility has adverse effects on the quality of life (QoL) of infertile couples. Previous studies found important associations between sexual function, self-esteem and QoL, but mainly focused on one individual's approach rather than both partners. This study adopted a dyadic approach to evaluate the relationship between sexual function and QoL in couples with infertility through mediation and improving self-esteem.

Exposure to multiple toxic metals and polycystic ovary syndrome risk: Endocrine disrupting effect from As, Pb and Ba.

Background: Polycystic ovarian syndrome (PCOS) affects 5 % ~ 20 % of women of reproductive age and is a serious health problem. Whether exposure to lead (Pb), mercury (Hg), arsenic (As), barium (Ba) or (cadmium) Cd is associated with an increased risk of PCOS, particularly their joint effect as well as their association with the clinical phenotype of PCOS is limited and unclear.

Objectives: We aimed to explore the associations of the blood Pb, Hg, As, Ba and Cd levels and risk of PCOS in Chinese women of reproductive age.

Environmental thallium exposure and the risk of early embryonic arrest among women undergoing in vitro fertilization: thallium exposure and polymorphisms of mtDNA gene interaction and potential cause exploring.

Early embryonic arrest (EEA) leads to cancelation of fresh cycles among infertile women undergoing in vitro fertilization (IVF), bringing a great challenge for IVF. Whether exposure to thallium (Tl) is associated with an increased risk of EEA, especially its interaction with polymorphisms of mitochondria DNA (mtDNA) gene, is worthy of study. A case-control design was performed, including 74 EEA cases with 123 IVF cycles and 157 age and BMI-matched controls with 180 IVF cycles.

A Novel Algicidal Bacterium, sp. YX04, Triggered Oxidative Damage and Autophagic Cell Death in , Which Causes Harmful Algal Blooms.

Phaeocystis globosa causes severe marine pollution by forming harmful algal blooms and releasing hemolytic toxins and is therefore harmful to marine ecosystems and aquaculture industries. In this study, sp. YX04 exerted high algicidal activity against P.

The potential of prodigiosin for control of Prorocentrum donghaiense blooms: Algicidal properties and acute toxicity to other marine organisms at various trophic levels.

Prorocentrum donghaiense, a marine dinoflagellate, causes harmful algal blooms (HABs) characterised by the highest outbreak frequency and most extensive coverage among similar species in the East China Sea. Highly efficient and ecofriendly biocontrol strategies should be developed for HAB control. Prodigiosin is an efficient biological algicide that demonstrated strong algicidal activity towards P.

Nutrient Deficiency and an Algicidal Bacterium Improved the Lipid Profiles of a Novel Promising Oleaginous Dinoflagellate, for Biodiesel Production.

The lipid production potentials of 8 microalgal species were investigated. Among these 8 species, the best strain was a dominant bloom-causing dinoflagellate, Prorocentrum donghaiense; this species had a lipid content of 49.32% ± 1.

Effects of plant diversity on greenhouse gas emissions in microcosms simulating vertical constructed wetlands with high ammonium loading.

Wastewater with relatively high nitrogen concentrations is a major source of nitrous oxide (NO) and methane (CH) emissions and exerts multiple stresses on the environment. Studies have shown that plant diversity plays an important role in ecosystem functioning. However, the effects of plant species diversity on CH and NO emissions under high ammonium (NH-N) loading rates remain unclear.
