Abstract
BACKGROUND Imbalances in alkali elements (AEs) and alkaline earth elements (AEEs) cause reproductive disorders. However, it remains unclear whether AEs/AEEs in follicular fluid have a relationship with the serious reproductive disorder known as diminished ovarian reserve (DOR). METHODS A nested case‒control study was carried out in China. Follicular fluid samples from 154 DOR patients and 154 controls were collected and assessed for nine AEs/AEE levels. Both the mixed and single effects of the elements on DOR were estimated with a Bayesian kernel machine (BKMR) and logistic regressions. RESULTS The DOR group had higher median concentrations of Li, Na, and K in follicular fluid (all P values < 0.05). The logistic regression showed that compared with their lowest tertile, the high tertiles of K [OR:2.45 (1.67-4.43)], Li [OR: 1.89 (1.06-3.42)], and Cs [OR: 1.97 (1.10-3.54)] were significantly associated with the odds of DOR. The BKMR model reported that the DOR likelihood increased linearly across the 25th through 75th percentiles of the nine-AE/AEE mixture, while the AE group contributed more to the overall effect. CONCLUSION This study revealed an association in which the likelihood of DOR increased with higher overall concentrations of AE/AEEs in follicular fluid. Among the nine detected elements, K, Li, and Cs exhibited significant individual associations with DOR. We provide new clues for the environmental factors on female fertility decline. TRIAL REGISTRATION Retrospectively registered.

Pomegranate (Punica granatum) peel alleviates lithium-induced alterations in the thyroid gland of rats by modulating apoptosis and oxidative stress. Anat Rec (Hoboken) 2023; 306:537-551. [PMID: 36370004 DOI: 10.1002/ar.25122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 10/05/2022] [Accepted: 10/26/2022] [Indexed: 11/13/2022]
Abstract
Lithium carbonate (LC) is known to alter thyroid gland function. Pomegranate (PG) is a fruit with multiple antioxidant and antiapoptotic properties. Here, we studied the effect of PG on LC-induced morphological and functional alterations in the thyroid glands of rats. Rats were divided into four groups: control, lithium, lithium-PG, and PG. After 8 weeks, the rats were sacrificed, the levels of thyroid hormones and oxidative stress markers were estimated, and thyroid tissues were subjected to histological, immunohistochemical, and ultrastructural evaluations. Compared to the control group, the lithium group showed significant changes in thyroid hormone levels, greater expression of the oxidant marker malondialdehyde, and lower expression of the antioxidant marker superoxide dismutase (SOD). Most of these changes improved upon PG treatment. Histological evaluation of the thyroid in the lithium group showed disorganization and follicle involution. Additionally, the periodic acid Schiff staining intensity and SOD immunoreactivity declined significantly, whereas the collagen fiber content and Bax immunoreactivity increased. The follicular ultrastructure showed marked distortion. These changes were mitigated upon PG treatment. In conclusion, PG alleviated the morphological and functional changes in the thyroid glands induced by LC by modulating apoptosis and oxidative stress.

Characterization of Aspergillus niger MK981235 xylanase with extraction of anti-hepatotoxic, antioxidant, hypocholesterolemic and prebiotic Corchorus olitorius stems xylooligosaccharides. Int J Biol Macromol 2020; 166:677-686. [PMID: 33152359 DOI: 10.1016/j.ijbiomac.2020.10.225] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 09/21/2020] [Accepted: 10/28/2020] [Indexed: 01/17/2023]
Abstract
The object of this study was to utilize agro-industrial waste Corchorus olitorius stems (molokhia stems, MS) as substrate, for Aspergillus niger MK981235 xylanase production and as source of biologically active xylooligosaccharides (XOS). This study succeeded in utilization of Aspergillus niger MK981235 xylanase under different saccharification conditions designed by central composite design (CCD) for extraction of 15 biologically active XOS (anti-hepatotoxic, antioxidant, hypocholesterolemic and prebiotic) with different monosaccharides constituents composition and percent. A. niger MK981235 xylanase showed the highest activity 6.60 U·ml-1 at 50 °C with 1.5% xylan. The kinetics included Km and Vmax were determined to be 6.67 mg·ml-1 and 20 μmol·ml-1·min-1, respectively. Moreover, A. niger MK981235 xylanase thermodynamics Ea (activation energy) and Ed (activation energy of denaturation) were determined to be 21.95 and 39.51 KJ·mol-1, respectively. The highest prebiotic effect (growth promation) was exerted by the central MS XOS on Lactobacillus plantarum and Lactobacillus rhamnosus (125 and 135.3%, respectively). Also, the central MS XOS, exerted the highest cholesterol reduction and antioxidant activities 74.7 and 92%, respectively, showed remarkable in vivo protective role against the hepatic toxicity of lithium carbonate evaluated by changes in body weight, liver function markers (AST, ALT, Alb, total bilirubin) and tissue makers (MDA and GSH).
