Abstract
Immune checkpoints regulate the immune system response. Recent studies suggest that flavonoids, known as phytoestrogens, may inhibit the PD-1/PD-L1 axis. We explored the potential of estrogens and 17 Selective Estrogen Receptor Modulators (SERMs) as inhibiting ligands for immune checkpoint proteins (CTLA-4, PD-L1, PD-1, and CD80). Our docking studies revealed strong binding energy values for quinestrol, quercetin, and bazedoxifene, indicating their potential to inhibit PD-1 and CTLA-4. Quercetin and bazedoxifene, known to modulate EGFR and IL-6R alongside estrogen receptors, can influence the immune checkpoint functionality. We discuss the impact of SERMs on PD-1 and CTLA-4, suggesting that these SERMs could have therapeutic effects through immune checkpoint inhibition. This study highlights the potential of SERMs as inhibitory ligands for immune checkpoint proteins, emphasizing the importance of considering PD-1 and CTLA-4 inhibition when evaluating SERMs as therapeutic agents. Our findings open new avenues for cancer immunotherapy by exploring the interaction between various SERMs and immune checkpoint pathways.

Abstract
Integrating fertility control techniques using steroid hormones after lethal control can help reduce post control rebuildup of rodent populations. The current study is the first to assess the antifertility effects of quinestrol in male lesser bandicoot rat, Bandicota bengalensis which is the predominant rodent pest species in Southeast Asia. Rats in different groups were fed bait containing 0.00%, 0.01%, 0.02%, and 0.03% quinestrol for 10 days in laboratory and evaluated immediately, and 15, 30, and 60 days after treatment discontinuation for effect on reproduction and other antifertility parameters. Effect of 0.03% quinestrol treatment for 15 days was also observed in managing rodent populations in groundnut crop fields. Treatment resulted in average consumption of 19.53 ± 1.80, 67.63 ± 5.50, and 246.67 ± 1.78 mg/kg bwt active ingredient by three treated groups of rats, respectively. No reproduction was observed in female rats mated with male rats treated with 0.03% quinestrol, even 30 days after cessation of treatment. Post-mortem examination showed a significant (P < 0.0001) effect of treatment on organ weights (testis, cauda epididymis, seminal vesicles, and prostate gland) and different sperm parameters (sperm motility, sperm viability, sperm count, and sperm abnormality) in the cauda epididymal fluid with partial reversibility after 60 days. A significant (P < 0.0001) effect of quinestrol on the histomorphology of testis and cauda epididymis was observed, suggesting its effect on spermatogenesis. Affected cell association and cell count in seminiferous tubules did not fully recover within 60 days of stopping treatment. Evaluation of the effects of quinestrol treatment in groundnut fields showed greater reductions in rodent activity in fields treated with 2% zinc phosphide followed by 0.03% quinestrol treatment as compared to fields treated with 2% zinc phosphide alone. Research concludes that quinestrol has the potential to reduce fecundity and post control rebuildup of B. bengalensis populations, but long-term studies of the effectiveness of quinestrol under large-scale field conditions are needed to use it as part of an integrated pest control program for rodents.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2023; 192:105408. [PMID: 37105635 DOI: 10.1016/j.pestbp.2023.105408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 03/07/2023] [Accepted: 03/22/2023] [Indexed: 06/19/2023]
Abstract
Anti-reproductive potential of papaya seed chloroform extract-based solid lipid nanoparticles (PSCEN) was investigated for the first time in lesser bandicoot rat, Bandicota bengalensis. Mature male rats (n = 30 per group) were fed bait (loose mixture of cracked wheat, powdered sugar, and groundnut oil in the ratio 88:10:2) containing two different concentrations of PSCEN (5% and 10%) in a bi-choice condition for 15 days with one group as vehicle control. The ingestion of active ingredient in 15 days treatment was significantly (P ≤ 0.05) higher by rats treated with 10% PSCEN (39.17-58.70 g/kg body weight) as compared to rats treated with 5% PSCEN (21.30-33.23 g/kg body weight). A dose dependent significant (P ≤ 0.05) decrease was observed in the level of testosterone, FSH, LH and GnRH in plasma of treated rats. A significant (P ≤ 0.05) decrease was also observed in level of total soluble proteins, total lipids, phospholipids and cholesterol in both plasma and testicular tissue, and level of 17β-HSD and 3β-HSD in testicular tissue indicating anti-reproductive effects of PSCEN treatment. There was observed significant (P ≤ 0.05) effect of treatment on histomorphology of testis and cauda epididymis in the form of reduced tubular diameter, germinal epithelial thickness, number of germ cells and dissociation of epithelial cycle in seminiferous tubules, and reduced tubular diameter, increased epithelial thickness, vacuolization, loose contact of principle cells and reduced number of spermatozoa in the cauda epididymal tubules. Maximum antifertility effect was observed with 10% PSCEN treatment, which was not reversed upto 105 days of treatment withdrawal indicating long-term efficacy. The current investigation suggests the use of PSCEN in the management of reproduction of B. bengalensis by exerting influence on testicular and cauda epididymal functions and biochemical parameters.

Abstract
PURPOSE The present study aimed to record the prevalence, risk factors, molecular identification, and phylogeny of Nippostrongylus brasiliensis found in the small intestine of the lesser bandicoot rat, Bandicota bengalensis, a wild rodent species. METHODS A total of 100 bandicoot rats live trapped at two commensal urban locations (50 each), i.e., a fish market and railway station, in Ludhiana, Punjab State (India), from November 2020 to October 2021, were analysed for the presence of N. brasiliensis, a nematode parasite of zoonotic importance. RESULT Overall, the small intestine of 43.00% of the rats was found severely infected with bright red coloured adult N. brasiliensis of both sexes (total of 1439 specimens). Faecal samples contained ellipsoidal and thin-shelled eggs measuring 62.25-74.70 m in length and 33.20-37.35 m in breadth. No significant (P > 0.05) effect of host age, sex, or season was observed on the rate of infection. The parasite intensity and mean abundance ranged from 27.68-38.04 and 10.52-18.26, respectively, indicating a high risk of disease transmission. Based on the morphology, the nematode parasite was identified as Nippostrongylus sp. Molecular identification was confirmed through PCR amplification of the mitochondrial cytochrome oxidase I gene, which showed a single band of approximately 355 bp. A comparison of the present isolate with the available sequences of Nippostrongylus species across the globe showed 100% nucleotide homology with N. brasiliensis sequences available in GenBank from Japan (AP017690), the USA (U57035), and New Zealand (NC033886). CONCLUSION The study indicates that B. bengalensis inhabiting commensal urban areas is a reservoir host for N. brasiliensis, which if transmitted to humans and animals visiting the area may pose a potential health risk. The study thus suggests proper rodent population management close to human habitations to avoid the transmission of disease-causing agents.

Abstract
Pesticides are widely used to control crop diseases, which have made an important contribution to the increase of global crop production. However, a considerable part of pesticides may remain in plants, posing a huge threat to animal safety. Thiram is a common pesticide and has been proven that its residues in the feed can affect the growth performance, bone formation, and intestinal health of chickens. However, there are few studies on the liver metabolism of chickens exposed to thiram. Here, the present study was conducted to investigate the effect of thiram exposure on liver metabolism of chickens. Metabolomics analysis shows that 62 metabolites were down-regulated (ginsenoside F5, arbekacin, coproporphyrinogen III, 3-keto Fusidic acid, marmesin, isofumonisin B1, 3-Hydroxyquinine, melleolide B, naphazoline, marmesin, dibenzyl ether, etc.) and 35 metabolites were up-regulated (tetrabromodiphenyl ethers, deoxycholic acid glycine conjugate, L-Palmitoylcarnitine, austalide K, hericene B, pentadecanoylcarnitine, glyceryl palmitostearate, quinestrol, 7-Ketocholesterol, tetrabromodiphenyl ethers, etc.) in thiram-induced chickens, mainly involved in the metabolic pathways including glycosylphosphatidylinositol (GPI)-anchor biosynthesis, porphyrin and chlorophyll metabolism, glycerophospholipid metabolism, primary bile acid biosynthesis and steroid hormone biosynthesis. Taken together, this research showed that thiram exposure significantly altered hepatic metabolism in chickens. Moreover, this study also provided a basis for regulating the use and disposal of thiram to ensure environmental quality and poultry health.

Abstract
The effect of combined levonorgestrel (P) and quinestrol (E) on the fertility of striped field mouse (Apodemus agrarius) has not been evaluated. We performed a series of experiments in both the laboratory and field to assess the effect of P and/or E on the fertility of A. agrarius. In the laboratory, to test the time-dependent anti-fertility effects of P and E, as well as their mixtures, 90 male striped field mice were randomly assigned to 6 treatment groups (n = 60), and a control group (n = 30). Mice in 3 treatment groups were administered 1 of the 3 compounds (1 mg⋅kg- 1 [body weight] EP-1, 0.34 mg⋅kg-1 E, 0.66 mg⋅kg-1 P) for 3 successive days (another half for 7 successive days) via oral gavage; mice were then sacrificed 15 and 45 days after initiating the gavage treatment. Our findings indicated that E and EP-1 treatment, but not P or control treatment, significantly decreased the sperm count in the caudal epididymis, as well as the weight of the testes, epididymides, and seminal vesicles. Additionally, fertile female mice mated with E- and EP-1-treated males produced smaller pups. These data indicate that E and EP-1 can induce infertility in male A. agrarius. In the field, the population density of A. agrarius was significantly influenced by EP-1, and the rodent density in the treatment group was lower than that in the control group. Overall, our results indicate that EP-1 is an effective contraceptive in A. agrarius, a dominant rodent species in the farmland.

Abstract
The black rat is considered one of the world's top pests. With increased restrictions on rodenticides, new alternatives to manage rats are urgently needed. Research on the use of contraceptive hormones, levonorgestrel (LE), and quinestrol (QU), have been evaluated against some rodent species, and this research is the first study to assess these on black rats. Hormones were incorporated into rodent bait at 10 and 50 ppm concentrations singly and in combination (EP-1). Groups of 10 animals of each sex were fed the baits over 7 days. Lower bait consumption was observed with slight body mass reductions. On dissection, it was observed that the uterus was in a state of edema and male reproductive organs weighed less with reduced sperm counts/motility. The 2 most promising baits, 50 ppm QU and EP-1, were used to assess impact on pregnancy and litter size. Pregnancy was reduced from 70% success when both males and females consumed untreated bait, down to 30% when males had consumed contraceptive bait but females had not, and down to 0% when females had consumed contraceptive bait, regardless of whether they had paired with a treated or untreated male. Litter size in the untreated pairs was 8 pups, but only 4 pups in those cases where the male only had consumed the contraceptive. Further studies should investigate how long the effect lasts and its reversibility. Field studies at the population level may also shed light on the practicality of using contraceptive baits for black rats in different habitats.
