Abstract
BACKGROUND AND STUDY AIM The klotho protein, a multifunctional protein, has been shown to be associated with a wide range of endocrine diseases and has been linked to thyroid tumourigenesis. However, the relationship between serum klotho levels and thyroid hormones remains poorly understood. This study aimed to explore the correlation between serum klotho levels and thyroid hormones. METHODS Data was obtained from the NHANES cycles 2007-2008, 2009-2010, and 2011-2012. A total of 4674 participants were recruited for this study. Statistical analysis was using multiple linear regression analyses, and restricted cubic spline plots (RCS) to investigate the association between serum klotho levels and serum levels of thyroid hormones. RESULTS In the unadjusted covariate model, ln(klotho) significantly positively correlated with tT3, tT4, fT3, tT4/fT4, and tT3/fT3 (all P<0.01) and negatively correlated with TSH, tT4/tT3, and fT4/fT3 (all P<0.05). Furthermore, tT3, tT4, fT3and tT3/fT3 (P < 0.05) were still significant in the adjusted model. And it is worth noting that there is an approximately L-shaped nonlinear relationship between ln(klotho) and fT3,tT3 with a cut-off point of 6.697 (P-non-linear < 0.05). The stratification analysis showed gender and iodine level differences in the relationship between serum Klotho levels and thyroid hormones. CONCLUSION There is an L-shaped nonlinear relationship between ln(klotho) and fT3, tT3, suggesting that klotho could be involved in the physiological regulation of thyroid function.

Abstract
BACKGROUND Bone mineral density is an important indicator of osteoporosis, and its variation with volatile organic compounds exposure has rarely been studied. However, the relationship between chloroform (an essential volatile organic compounds component) and bone mineral density remains unclear. Consequently, we aimed to explore the relationship between chloroform alone and bone mineral density or bone mineral content. METHODS Herein, 2,553 individuals aged 18 and above from the National Health and Nutrition Examination Surveys (NHANES) in 2009-2010, 2013-2014, and 2017-2020, were included. We employed two independent t-tests and multi-linear regression models to statistically assess the relationship between chloroform exposure and BMD/BMC in the spine and femoral area. RESULTS A "V"-shaped correlation between chloroform exposure and bone mineral density or bone mineral content (BMD/BMC) was observed in the unadjusted model, particularly in the Ward's triangle and femoral neck as a whole. A negative correlation was specifically observed for the Ward's triangle BMD/BMC and L4 BMD/BMC. On the other hand, in the adjusted model, a dominantly negative correlation between the L4 BMC and chloroform exposure was observed over a range of exposure levels. The subgroup analysis revealed a negative correlation between chloroform concentrations and BMC in the femur and spine, especially in women and the 65-80 age population. CONCLUSION Our study revealed a "V" shaped correlation between chloroform and BMD/BMC of the femur and spine in U.S. adults. This finding highlights the fact that prolonged exposure to chloroform may cause the changes in BMD/BMC.

Abstract
The present study utilized the National Health and Nutrition Examination Survey (NHANES) database to examine the relationship between serum levels of heavy metals and Diabetic retinopathy (DR) in individuals aged over 30 years with type 2 diabetes mellitus (T2DM) in the United States. A cross-sectional analysis was conducted on 1583 individuals with T2DM from the NHANES 2011-2020, including 331 individuals in the DR group and 1252 individuals in the non-DR group. We collected data on serum levels of heavy metals, DR, and serum albumin for descriptive statistics, linear regression, and logistical regression analysis. After adjusting for age, gender, race and other factors, there was no statistically significant association between blood cadmium, selenium, mercury, or lead and DR. However, serum manganese (Mn) and DR had a significant negative association (β = - 0.2045, 95% CI = - 0.3484, - 0.0606). Serum albumin partially modulated the indirect influence of serum Mn on the incidence of DR, accounting for 12.80% of the association between serum Mn and DR. There was a negative association between serum Mn levels and the prevalence of DR in people with T2DM. Mn intake at least in this study has a little influence on the onset and development of DR.

Abstract
AIMS To identify and evaluate the application of two novel monoclonal antibody (mAb) 2G12 against outer membrane protein (Omp) C and mAb 12B1 targeting the O chain of the lipopolysaccharides (LPS) of Escherichia coli O157:H7 (ECO157). METHODS AND RESULTS The sensitivity and specificity of these two antibodies were evaluated with eight ECO157 strains and 68 untargeted strains. mAb 2G12 and 12B1 had no detectable binding with any of the non-O157 strains at 6·0 log10 CFU per ml, while its high specificity and affinity remained with all ECO157 strains. When a higher level (8·0 log10 CFU per ml) was tested, 2G12 and 12B1 did not react with 82·35 and 97·06% of the non-O157 strains respectively. Based on the pair of two antibodies, the sandwich enzyme-linked immunosorbent assay detected 100% (8/8) of ECO157 strains and none of the non-ECO157 strains. The detection limit of ECO157 strains in pure culture were 4·2 ± 0·2 log10 CFU per ml. When the developed test was applied to artificially inoculated beef samples, the detection limit was 6·0 log10 CFU per gram without enrichment and 1·0 log10 CFU per gram after 12 h of enrichment. CONCLUSIONS The two novel antibodies identified in this study served as great candidates for the recovery, and detection of ECO157 from different environmental and food samples. SIGNIFICANCE AND IMPACT OF THE STUDY ECO157-specific detection was improved by a combination of the novel OmpC mAb and LPS mAb with defined target antigen and good specificity.

Abstract
BACKGROUND Dipeptidyl peptidase-4 (DPP-4) inhibitor and pioglitazone combination therapy have been widely used for patients with inadequate glycemic control on monotherapy. This meta-analysis assessed the efficacy and safety of this combination therapy in patients with type 2 diabetes mellitus (T2DM). METHODS We searched the MEDLINE, Embase, and Cochrane databases. Studies were eligible if they were randomized controlled trials (RCTs) on DPP-4 inhibitor and pioglitazone combination therapy in patients with T2DM through the end of February 2016, using the keywords "alogliptin," "dutogliptin, " "linagliptin," "saxagliptin," "sitagliptin," "vildagliptin," "gliptins," "DPP-4 inhibitor," and "pioglitazone." RCTs were selected if they compared DPP-4 inhibitors and pioglitazone as combination therapy; treatment duration was ≥12 weeks; and the reported data included hemoglobin A1c (HbA1c) or fasting plasma glucose (FPG) change, total or any other system Adverse Events (AEs). We estimated effect size with random-effects or fixed-effects meta-analysis, I statistic was used to estimate heterogeneity of results. RESULTS Seven RCTs were included. Compared with pioglitazone monotherapy, combination DPP-4 inhibitor and pioglitazone therapy were associated with increased reduction in HbA1c ([MD]-0.64%;-0.73 to -0.55) and FPG ([MD] -0.94; -1.12 to -0.76) levels, more patients in the combination therapy groups versus pioglitazone monotherapy groups had an A1c of < 7% ([OR]2.52; 2.18, 3.17) at the end of the studies, but was not associated with further reduction in higher risk of hypoglycaemia, edema, or any other system AEs. We also noticed that DPP-4 inhibitor and pioglitazone combination therapy were associated with better improvement of pancreatic β-cell function. CONCLUSIONS DPP-4 inhibitor and pioglitazone combination therapy provided better glycemic control, both according to HbA1c and FPG levels, than pioglitazone monotherapy. Safety analysis showed well tolerance of combination therapy, even in hypoglycemic and edema AEs. However, additional large-scale, high quality, long-term follow-up clinical trials are necessary to confirm its long-term effectiveness.

Abstract
Co-occurrence of aflatoxin B1 (AFB1) and deoxynivalenol (DON) is one of the most common mycotoxin contaminations in cereal crops and food ingredients. However, the mechanism of their combined toxicity is poorly understood. In the current investigation, the hepatoma HepG2/C3A cell line was used to explore the combined cytotoxicity of AFB1 and DON. The values of IC50, based on a sulforhodamine B (SRB) assay, were 4.5 mM and 18.7 mM for DON and AFB1, respectively. The analysis of cytotoxicity endpoints using the combination index (CI) theory revealed that the changes of mitochondrial membrane permeability and ATP resulted from an additive cytotoxic effect (CI≈1) of AFB1 and DON. However, the endpoints of double strand DNA (ds-DNA), reactive oxygen species (ROS) and cell viability (SRB) were synergistically (CI<1) affected in a dose-dependent manner. RNA-seq analysis demonstrated a number of uniquely expressed genes in their combination (AFB1: 2.5 mM, DON: 0.56 mM), indicating a synergistic interaction between AFB1 and DON at a molecular level. Additional transcriptomics analysis showed that the endoplasmic reticulum stress-associated JNK/p38/MAPK pathway was induced by DON, whereas the p53 signalling pathway was activated by AFB1. The expression profiles of apoptosis-related genes caspase-3, Bax and Bcl-2 suggested a mitochondria-mediated apoptosis pathway that was shared between AFB1 and DON. Thus, different cytotoxicity pathways and their converging at the apoptotic process might be the mechanism of the additive/synergistic cytotoxicity of AFB1 and DON to HepG2/C3A cells.

Abstract
We quantitatively discuss the influence of quenched disorder on the ferromagnetic quantum phase transition in metals, using a theory that describes the coupling of the magnetization to gapless fermionic excitations. In clean systems, the transition is first order below a tricritical temperature T_{tc}. Quenched disorder is predicted to suppress T_{tc} until it vanishes for residual resistivities ρ_{0} on the order of several μΩ cm for typical quantum ferromagnets. We discuss experiments that allow us to distinguish the mechanism considered from other possible realizations of a first-order transition.

Abstract
Acute-on-chronic hepatitis B liver failure (ACHBLF) has a poor prognosis in patients with hepatitis B virus infection. The role of the neutrophil-lymphocyte ratio (NLR), which reflects the inflammatory status of the patient before treatment, has never been studied in this setting. To investigate the predictive value of NLR in patients with ACHBLF, a retrospective cohort with 216 patients and a prospective validation cohort with 73 patients were recruited. Multivariate analyses showed that total bilirubin (TBIL), NLR, age and model for end-stage liver disease (MELD) score had prognostic significance for survival. Both NLR (0.781) and MELD score (0.744) had higher ROC curves, which differed significantly from those for age (0.615) and TBIL (0.691), but not from each other (P = 0.94). NLR ≤ 2.36 predicted lower mortality (with 91.6% sensitivity and 86.0% negative predictive value), and NLR >6.12 was a warning sign for higher mortality risk (with 90.1% specificity and 80.3% positive predictive value). These results demonstrated that pretreatment NLR was associated with the prognosis of patients with ACHBLF, and elevated NLR predicted poor outcome within 8 weeks. We suggest that NLR cut-offs of ≤ 2.36 and >6.12 are powerful markers for predicting mortality in ACHBLF.

Abstract
Downregulation of hSSB1, a single-stranded DNA-binding protein, causes increased radiosensitivity, defective checkpoint activation and genomic instability. However, the mechanisms of hSSB1 function in these responses remain to be uncovered. Here, we present evidence that hSSB1 directly binds p21 and this interaction may prevent p21 from ubiquitin-mediated degradation. Furthermore, both promotion of the G1/S transition and abrogation of the G2/M checkpoints induced by hSSB1 knockdown are partially dependent on p21. Most importantly, hSSB1 and p21 levels are positively correlated in human hepatocellular carcinomas (HCC), as determined by immunostaining. Therefore, hSSB1 may positively modulate p21 to regulate cell cycle progression and DNA damage response, implicating hSSB1 as a novel, promising therapeutic target for cancers such as HCC.

Abstract
We model friction acting on the tip of an atomic force microscope as it is dragged across a surface at nonzero temperatures. We find that stick-slip motion occurs and that the average frictional force follows (absolute value lnv)(2/3), where v is the tip velocity. This compares well to recent experimental work, permitting the quantitative extraction of all microscopic parameters. We calculate the scaled form of the average frictional force's dependence on both temperature and tip speed as well as the form of the friction-force distribution function.

Abstract
Phospholipase D (PLD) has been implicated in various processes, including signal transduction, membrane trafficking, and membrane degradation. Multiple forms of PLD with distinct biochemical properties have been described in the cell. In Arabidopsis, PLDalpha and PLDgamma, but not PLDbeta, were detected in guard cells, and antisense suppression resulted in a specific loss of PLDalpha. The abrogation of PLDalpha rendered plants less sensitive to abscisic acid and impaired stomatal closure induced by water deficits. PLDalpha-depleted plants exhibited accelerated transpirational water loss and a decreased ability to tolerate drought stress. Overexpression of PLDalpha enhanced the leaf's sensitivity to abscisic acid. These findings provide molecular and physiological evidence that PLDalpha plays a crucial role in regulating stomatal movement and plant-water status.

Abstract
Phospholipase D (PLD), which hydrolyzes phospholipids into free head groups and phosphatidic acid (PA), may regulate cellular processes through the production of lipid and lipid-derived messengers. We have genetically abrogated PLD alpha, the most prevalent isoform of PLD in plants, and the depletion of PLD alpha in Arabidopsis decreased the levels of PA and superoxide production in Arabidopsis leaf extracts. Addition of PA promoted the synthesis of superoxide in the PLD alpha-depleted plants, as measured by chemiluminescence and superoxide dismutase-inhibitable, NADPH-dependent reduction of cytochrome c and nitroblue tetrazolium. The PA-enhanced generation of superoxide was associated mainly with microsomal membranes. Among various lipids tested, PA was the most effective stimulator with the optimal concentrations between 100 and 200 microM. The PA-promoted production of superoxide was observed also in leaves directly infiltrated with PA. The added PA was more effective in stimulating superoxide generation in the PLD alpha-depleted leaves than in the PLD alpha-containing, wild-type leaves, suggesting that PA produced in the cell was more effective than added PA in promoting superoxide production. These data indicate that PLD plays a role in mediating superoxide production in plants through the generation of PA as a lipid messenger.

Abstract
OBJECTIVE To study the relationship between human leukocyte antigen (HLA)-DRB1 and DQ alleles and the genetic susceptibility of type 1 diabetes in North Chinese children. METHODS Polymerase chain reaction (PCR) techniques were used to amplify the second exon of DRB1 and DQ alleles, after which sequence specific olignucleotide probe (SSOP) dot blot hybridization techniques were used to analyze the amplified products. RESULTS DRB1 * 0301, DQA1 * 0301, DQB1 * 0201 alleles and DRB1 * 0301-DQA1 * 0501-DQB1 * 0201 haplotype were significantly increased in patients, while DQA1 * 0103 and DQB1 * 0601 alleles were significantly increased in controls. The distribution of DR4 and DR9 haplotypes in patients and controls were not significantly different, but DR3/DR4 and DR4/DR9 heterozygotes were significantly increased in patients. CONCLUSIONS DRB1 * 0301, DQA1 * 0301 and DQB1 * 0201 confer susceptibility while DQA1 * 0103 and DQB1 * 0601 confer protection to type 1 diabetes. DRB1 * 0301-DQA1 * 0501-DQB1 * 0201 haplotype offers a predisposition to type 1 diabetes in North Chinese. Although the distribution of DR4 and DR9 in patients and controls had no significant difference, DR3/DR4 and DR3/DR9 heterozygotes were significantly increased in patients, showing that the susceptive effects of DR3 and DR4 or DR4 and DR9 haplotypes could be added up.

Abstract
Phospholipase D (PLD) is encoded by a multiple gene family, and several PLDs from Arabidopsis have been characterized at the molecular biological and biochemical levels. PLDalpha is the most abundant plant PLD and exhibits a number of different biochemical properties to the other isoforms. The other PLDs have many overlapping catalytic properties but display some unique patterns of expression during development and in response to stress cues. Accumulating data indicate that different PLDs have multiple and different roles in plant responses to stress.

Abstract
The physical locations of the 18S-5.8S-26S rDNA sequences were examined in three sorghum species by fluorescence in situ hybridization (FISH) using biotin-labeled heterologous 18S-5.8S-26S rDNA probe (pTa71). Each 18S-5.8S-26S rDNA locus occurred at two sites on the chromosomes in Sorghum bicolor (2n = 20) and S. versicolor (2n = 10), but at four sites on the chromosomes of S. halepense (2n = 40) and the tetraploid S. versicolor (2n = 20). Positions of the rDNA loci varied from the interstitial to terminal position among the four accessions of the three sorghum species. The rDNA data are useful for investigation of chromosome evolution and phylogeny. This study excluded S. versicolor as the possible progenitor of S. bicolor.

Abstract
To study the effects of Chinese herbal medicine Tangshenkang (TSK) capsule on diabetic nephropathy (DN), 57 patients with DN were randomly divided into two groups, the treated group and the control group, they were treated with TSK capsule and the conventional therapy respectively. There were serious disorders of metabolism in DN patients, that showed the TXB 2/6-keto-PGF1 alpha ratios and lipid peroxidase (LPO) levels were higher than that of healthy people. After 6 weeks treated with TSK capsule the albuminuria levels reduced obviously (decreased 51%), renal plasma flow (RPF) increased, glomerular filtration rate and the LPO levels decreased and a positive correlation was observed between albuminuria levels and TXB 2/6-keto-PGF1 alpha ratios while the clearance rate of creafinin didn't improve significantly. There were no significant difference in the above-mentioned parameters in the control group before and after treatment. These results suggested that TSK capsule possessed a significant effect in improving albuminuria and glomerular function. And the effect of TSK might be due to its adjusting TXB 2/6-keto-PGF1 alpha ratios and its lipid-peroxidation in DN patients.

Abstract
The galactic cosmic rays (GCR) contain fully stripped nuclei, from Hydrogen to beyond the Iron group, accelerated to high energies and are a major component of the background radiation encountered by satellites and interplanetary spacecraft. This paper presents a GCR model which is based upon our current understanding of the astrophysics of GCR transport through interstellar and interplanetary space. The model can be used to predict the energy spectra for all stable and long-lived radioactive species from H to Ni over an energy range from 50 to 50,000 MeV/nucleon as a function of a single parameter, the solar modulation level phi. The details of this model are summarized, phi is derived for the period 1974 to present, and results from this model during the 1990/1991 CRRES mission are presented.
