Detrimental effects of cadmium on male infertility: A review.

Infertility has become a serious health and socio-economic-psychological problem globally. The harmful role of trace metals in male infertility is recognized but still not sufficiently explained. Herein, a comprehensive review was conducted to elucidate the detrimental role of cadmium (Cd) on male infertility, particularly on infertility with unknown (idiopathic) causes.

Individualized dosing of rec-FSH for ovarian stimulation in women with PCOS reduces asynchronous follicle growth.

Purpose: We aimed to evaluate if ovarian stimulation with individualized dosing of recombinant follicle-stimulating hormone (rec-FSH) with follitropin delta compared with standard gonadotropin dosing reduce occurrence of follicular asynchrony in women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF).

Methods: Matched case-control study analyzed occurrence of follicular growth asynchrony during ovarian stimulation and IVF outcomes in women with PCOS. Follicular growth was considered to be asynchronous when one or two leading follicles were at least 4 mm larger in diameter than the rest of the cohort on day 5 and 9 of stimulation.

Novel Green Strategy to Recover Bioactive Compounds with Different Polarities from Horned Melon Peel.

Around 20-30% of the horned melon's weight is peel. This peel is often discarded or underutilized despite containing valuable bioactive compounds. Conventional methods for extracting polyphenols and carotenoids from horned melon peel are typically inefficient, environmentally harmful, or require significant time and energy.

The Impact of High-Dose Fish Oil Supplementation on Mfsd2a, Aqp4, and Amyloid-β Expression in Retinal Blood Vessels of 5xFAD Alzheimer's Mouse Model.

In patients with Alzheimer's disease (AD) and in animal models, the increased accumulation of amyloid β (Aβ) in retinal blood vessels strongly correlates with brain amyloid deposits and cognitive decline. The accumulation of Aβ in blood vessels may result from impaired transcytosis and a dysfunctional ocular glymphatic system in AD. High-dose fish oil (FO) supplementation has been shown to significantly change the expression of major facilitator superfamily domain-containing protein 2a (Mfsd2a), a key regulator of transcytosis, and Aquaporin 4 (Aqp4), an essential component of the glymphatic system in the retinas of WT mice.

Effects of Prenatal Dexamethasone Treatment and Post-Weaning Moderate Fructose Intake on Synaptic Plasticity and Behavior in Adult Male Wistar Rat Offspring.

Early-life glucocorticoid overexposure induces diverse neurodevelopmental outcomes regarding stress reactivity and cognition. Increased fructose consumption has also been associated with alterations in cognitive capacity and behavior. The present study investigated the effects of prenatal dexamethasone exposure on synaptic plasticity, locomotion, anxiety, and recognition memory in adult male Wistar rat offspring, and whether these effects are potentiated by postnatal fructose consumption.

The comprehensive evaluation of nitrate origin and transformation pathways in the oxic alluvial aquifer in Serbia.

Accurate pollution source identification is essential for establishing adequate water management strategies, particularly in groundwater with slow flow and prolonged recharge process allowing long-term pollution retention. An integrated study based on hydrogeochemical, dual isotopic (δN and δO), and microbiological approaches (DN, IRB, and SRB BART tests) along with the statistical data processing was conducted to determine nitrate origin and fate in oxic alluvial groundwater source Ključ in Serbia. The findings from a comprehensive investigation, encompassing 20 groundwater sampling locations during the period 2010-2019, delineated three distinct zones - the hinterland (anthropogenic impact area-untreated sewage inflow), the middle zone (area of mixed influence from fertilizer application, accompanied by a mitigated anthropogenic impact), and the zone of riparian denitrification.

Updating the on the Eco-Friendly Approach for Antioxidants Recovered from Plant Matrices Using Cloud Point Extraction.

The concepts of "green chemistry" are gaining importance in the agri-food sector due to the need to minimize pollution from toxic chemicals, improve the safety and sustainability of industrial processes, and provide "clean-labeled products" required by consumers. The application of the cloud point extraction (CPE) is considered a promising alternative to conventional organic solvents. In the CPE, the separation of compounds from the bulk solution occurs by adding a surfactant (either non-ionic or ionic).

Learning exceptions to category rules varies across the menstrual cycle.

Ways in which ovarian hormones affect cognition have been long overlooked despite strong evidence of their effects on the brain. To address this gap, we study performance on a rule-plus-exception category learning task, a complex task that requires careful coordination of core cognitive mechanisms, across the menstrual cycle (N = 171). Results show that the menstrual cycle distinctly affects exception learning in a manner that parallels the typical rise and fall of estradiol across the cycle.

Augmenting Functional and Sensorial Quality Attributes of Kefir through Fortification with Encapsulated Blackberry Juice.

Kefir is a fermented dairy product claimed to confer many health-promoting effects, but its acidic taste is not appealing to some consumers. Therefore, the aim of this study was to enhance the functional and sensorial quality attributes of kefir through fortification with encapsulated blackberry juice (EBJ). The blackberry juice was successfully encapsulated via freeze-drying using lentil protein isolate (LPI) as the carrier.

Disturbed sleep is associated with reduced verbal episodic memory and entorhinal cortex volume in younger middle-aged women with risk-reducing early ovarian removal.

Introduction: Women with early ovarian removal (<48 years) have an elevated risk for both late-life Alzheimer's disease (AD) and insomnia, a modifiable risk factor. In early midlife, they also show reduced verbal episodic memory and hippocampal volume. Whether these reductions correlate with a sleep phenotype consistent with insomnia risk remains unexplored.

The Expression of Major Facilitator Superfamily Domain-Containing Protein2a (Mfsd2a) and Aquaporin 4 Is Altered in the Retinas of a 5xFAD Mouse Model of Alzheimer's Disease.

Cerebral amyloid angiopathy (CAA) is characterized by amyloid β (Aβ) accumulation in the blood vessels and is associated with cognitive impairment in Alzheimer's disease (AD). The increased accumulation of Aβ is also present in the retinal blood vessels and a significant correlation between retinal and brain amyloid deposition was demonstrated in living patients and animal AD models. The Aβ accumulation in the retinal blood vessels can be the result of impaired transcytosis and/or the dysfunctional ocular glymphatic system in AD and during aging.

The main predictive factors of worse outcome in patients with COVID-19 infection hospitalized in temporary COVID hospital.

Introduction: After the Serbian community hospitals had reached their full capacity during the pandemic, new institutions were enrolled into the coronavirus disease 2019 (COVID-19) system as temporary COVID hospitals (TCH). These hospitals usually had no intensive care units (ICU) and no possibility to treat severely ill patients. The aim of this study was to identify risk factors at the time of triage that could help identify patients that will require ICU treatment and cannot be treated in a TCH.

The presymptomatic treatment with 3HFWC nanosubstance decreased plaque load in 5XFAD mouse model of Alzheimer's disease.

Introduction: In the present study, we assessed the effects of the hyper-harmonized-hydroxylated fullerene-water complex (3HFWC) on Alzheimer's disease (AD) neuropathological hallmarks in 5XFAD mice, an AD animal model.

Methods: The 3-week-old 5XFAD mice were exposed to 3HFWC water solution ad libitum for 3 months in the presymptomatic phase of pathology. The functional effects of the treatment were confirmed through near-infrared spectroscopy (NIRS) analysis through machine learning (ML) using artificial neural networks (ANNs) to classify the control and 3HFWC-treated brain tissue samples.

The double-edged sword of PCOS and gender: exploring gender-diverse experiences of polycystic ovary syndrome.

Past research on polycystic ovary syndrome (PCOS), a chronic endocrine condition, has focused on the experiences of cisgender women. The purpose of the present study was to address the knowledge gap about gender-diverse individuals by exploring their lived experiences with PCOS and to better understand if and how their gender identity affected their experience of PCOS. To explore this, we recruited nine non-binary people and one transgender man with a PCOS diagnosis for qualitative interviews.

Integration of enzymatic modification and ultrafiltration for the production of pectin fractions with highly potent antioxidant capacity as green valorization of sugar beet pulp.

Enzymatic hydrolysis of pectin followed by ultrafiltration of hydrolysate was applied with the aim to produce fractions with potent antioxidant capacity. Pectin was isolated from waste sugar beet pulp by acidic extraction, washed by diafiltration and concentrated by ultrafiltration. Enzymatic hydrolysis was performed with endo-polygalacturonase, and hydrolysate was processed by ultrafiltration into four fractions using membranes in series of decreasing cut-offs from 10 to 1 kDa.

Food Restriction Counteracts Dexamethasone-Induced Downregulation of Genes Involved in Cholesterol Homeostasis in Rat Brain during Aging.

Glucocorticoids are the most potent anti-inflammatory agents known. Limited in vivo data are available to characterize the mechanism underlying their cognitive side effects and transient occurrence of steroid psychosis. Cholesterol is important for proper neurotransmission and brain plasticity, and disruption of its homeostasis in the brain has been closely associated with memory decline during aging and in age-related neurodegenerative disorders.

Review of the effects of polycystic ovary syndrome on Cognition: Looking beyond the androgen hypothesis.

Polycystic-ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age, and many features associated with PCOS - such as elevated androgens, insulin resistance and inflammation - are known to affect cognition. However, effects of PCOS on cognition are not well-understood. Here we review the current literature on PCOS and cognition, note the extent of PCOS symptomatology studied in relation to cognitive outcomes, and identify key research gaps and common methodological concerns.

Elemental profiling of human semen with confirmed normozoospermia: Baseline levels for 44 elements.

Background: As a consequence of the progressive decline in human semen quality in recent decades, modern epidemiological investigations have identified several trace elements that could be responsible for this phenomenon. However, their levels in semen have not been clearly elucidated, particularly for elements present in ultra-trace levels.

Methods: We aimed to determine the levels of 39 (ultra)trace elements and 5 macroelements in human semen samples with confirmed normozoospermia using ICP-based techniques.

Examination of Trace Metals and Their Potential Transplacental Transfer in Pregnancy.

With the ever-growing concern for human health and wellbeing, the prenatal period of development requires special attention since fetuses can be exposed to various metals through the mother. Therefore, this study explored the status of selected toxic () and essential trace metals () in the umbilical cord (UC) sera, maternal sera, and placental tissue samples of 92 healthy women with normal pregnancies. A further aim focuses on the potential transplacental transfer of these trace metals.

Levels of non-essential trace metals and their impact on placental health: a review.

According to recent research, even low levels of environmental chemicals, particularly heavy metals, can considerably disrupt placental homeostasis. This review aims to explore the profile of non-essential trace metals in placental tissues across the globe and to specify trace metal(s) that can be candidates for impaired placental health. Accordingly, we conducted an extensive survey on relevant databases of peer-reviewed papers published in the last two decades.

Sex and Gender Science: The World Writes on the Body.

Sex and Gender Science seeks to better acknowledge that the body cannot be removed from the world it inhabits. We believe that to best answer any neuroscience question, the biological and the social need to be addressed through both objective means to learn, "how it is like" and subjective means to learn, "what it is like." We call bringing the biological and social together, "Situated Neuroscience" and the mixing of approaches to do so, Very Mixed Methods.
