Cost-utility analysis and drug pricing for tirzepatide for type 2 diabetes in the Chinese market compared with semaglutide.

AIM: To investigate the most matchable price of tirzepatide (TIRZ) compared with semaglutide (SEMA) in the treatment of type 2 diabetes in China. METHODS: The patient cohort and clinical efficacy data were derived from the SURPASS-2 trial. Cost-utility analysis and a binary search were performed to identify the most matchable price of TIRZ from a Chinese healthcare provider's perspective. RESULTS: After lifetime simulation, the quality-adjusted life years of TIRZ 5, 10, 15 mg and SEMA 1 mg were 11.17, 11.21, 11.27 and 11.12 years, respectively. Despite an initial assumption that the annual cost of TIRZ equals that of SEMA, our analysis revealed that TIRZ is probably more cost-effective than SEMA. A thorough evaluation of pricing showed that the cost ranges for TIRZ at doses of 5, 10 and 15 mg were $1628.61-$1846.23, $1738.40-$2140.95 and $1800.30-$2430.81, respectively. After adjustment in the univariate sensitivity analysis, the cost ranges for TIRZ 5, 10 and 15 mg were $1542.68-$1757.57, $1573.00-$1967.16 and $1576.54-$2133.96, respectively. These cost intervals were validated through robust probabilistic sensitivity analysis and scenario analysis, except for the cost range for TIRZ 5 mg. CONCLUSIONS: This study shows that, using SEMA as a reference, the annual costs for TIRZ 10 and 15 mg are $1573.00-$1967.16 and $1576.54-$2133.96, respectively, for patients with type 2 diabetes in China.

Glucagon-like peptide-1 receptor agonists decrease hyperinsulinemia and hyperandrogenemia in dehydroepiandrosterone-induced polycystic ovary syndrome mice and are associated with mitigating inflammation and inducing browning of white adipose tissue†.

Polycystic ovary syndrome is a complicated hormonal and metabolic disorder. The exact pathogenesis of polycystic ovary syndrome is not clear thus far. Inflammation is involved in the progression of polycystic ovary syndrome. In addition, brown adipose tissue activity is impaired in polycystic ovary syndrome. Interestingly, glucagon-like peptide-1 receptor agonists have been reported to alleviate inflammation and promote browning of white adipose tissue. In this study, the effects of glucagon-like peptide-1 receptor agonists on polycystic ovary syndrome mice were explored. Mice were randomly assigned into four groups: control, dehydroepiandrosterone, dehydroepiandrosterone + liraglutide, and dehydroepiandrosterone + semaglutide. Relative indexes were measured after glucagon-like peptide-1 receptor agonist intervention. Glucose metabolism in polycystic ovary syndrome mice was ameliorated by glucagon-like peptide-1 receptor agonists, while the reproductive endocrine disorder of polycystic ovary syndrome mice was partially reversed. The messenger ribonucleic acid levels of steroidogenic enzymes and the expression of inflammatory mediators in serum and ovaries of polycystic ovary syndrome mice were improved. Furthermore, toll-like receptor 4 and phosphorylation of nuclear factor-kappa B protein levels were decreased by glucagon-like peptide-1 receptor agonists in ovary. Notably, after glucagon-like peptide-1 receptor agonist intervention, the expression of brown adipose tissue marker levels was considerably raised in the white adipose tissue of polycystic ovary syndrome mice. In conclusion, the hyperinsulinemia and hyperandrogenemia of polycystic ovary syndrome mice were alleviated by glucagon-like peptide-1 receptor agonist intervention, which was associated with mitigating inflammation and stimulating adipose tissue browning.

High-Efficiency Extraction of Pantoea alhagi Exopolysaccharides Driven by pH-Related Changes in the Envelope Structure.

Increasing numbers of exopolysaccharides and their properties have been explored. However, the difficulty of extracting high-viscosity exopolysaccharides has hindered their further industrialization. In this research, we explored a strategy based on encapsulated structure control under different pH to efficiently extract Pantoea alhagi exopolysaccharides (PAPS). Results showed that at pH levels of 6, 12, and 13, the extraction efficiency of PAPS was elevated, and the yield did not decrease. The rheological properties of the pH-12-treated PAPS were better than those of PAPS treated at pH 7, while the pH-6-treated PAPS decreased. The effects of pH-12-treated PAPS on soil macroaggregates and soil's water evaporation rate were similar to those of PAPS treated at pH 7. In addition, we observed that treatment at pH 12 produced a significantly reduced encapsulated structure compared with treatment at pH 7. The proportion of unsaturated fatty acids after treatment at pH 12 was higher than after treatment at pH 7, which may result in reduced encapsulated structure in pH-12 conditions. These results enrich the understanding of the effect that alters pH conditions on the encapsulated structure to improve the extraction efficiency of exopolysaccharides and provide a theoretical basis for the extraction of exopolysaccharides with extreme viscosity.

LncRNA TUG1 reduces inflammation and enhances insulin sensitivity in white adipose tissue by regulating miR-204/SIRT1 axis in obesity mice.

Prevalence of obesity becomes an important health issue worldwide, but the management of obesity remains unsatisfied. This study aimed to explore the mechanism of long non-coding RNA TUG/miR-204/SIRT1 axis, which was involved in the pathogenesis of obesity. Obesity mouse model was induced by high-fat diet and treated with taurine upregulated gene1 (TUG1) virus via tail intravenous injection. Then, body weight, serum glucose, insulin tolerance, testicular fat weight were detected, as well as the expression of TUG1, microRNA-204 (miR-204), sirtuin1 (SIRT1), and inflammation and fatty accumulation associated proteins and cytokines. Regulatory relationship between TUG1/SIRT1 and miR-204 was confirmed by dual-luciferase reporter activity assay. A high-glucose-induced 3T3-L1 cell model was also constructed to explore the regulatory mechanism of TUG/miR-204/SIRT1 axis in the pathogenesis of obesity at cell level after altering the expression of TUG1, miR-204, and SIRT1. Overexpression of TUG1 could significantly attenuate the weight, serum glucose, glucose, insulin tolerance, fatty accumulation, and inflammation in obesity mice, as well as the elevation of miR-204, but increase the expression of SIRT1, phosphorylated AKT (p-AKT), glucose transporter4 (GLUT4), and peroxisome proliferator activated receptorγ (PPARγ). Both TUG1 and SIRT1 were targets of miR-204 and could be negatively regulated by miR-204. Overexpression of TUG1 could suppress the inflammation in adipocytes via downregulating miR-204 and promote GLUT4/PPARγ/AKT pathway high-glucose-induced inflammation in 3T3-L1 cells. miR-204 inhibitors could also suppress high-glucose-induced inflammation in 3T3-L1 cells via promoting SIRT1/ GLUT4/PPARγ/AKT pathway. LncRNA TUG1 could negatively regulate miR-204 to alleviate inflammation and insulin tolerance via promoting SIRT1/GLUT4/PPARγ/AKT pathway.

Postpartum assessment of the beta cell function and insulin resistance for Chinese women with previous gestational diabetes mellitus.

Gestational diabetes mellitus (GDM) imparts a high risk of developing postpartum diabetes and is considered to be an early stage of type 2 diabetes mellitus (T2DM). In this study, a 75-g oral glucose tolerance test was performed on 472 women with GDM at 6-8 weeks after delivery. The clinical and metabolic characteristics were compared between the patients with normal glucose tolerance (NGT) and abnormal glucose metabolism (AGM). These data were then compared between pre-diabetic and diabetic patients. A total of 37.7% of the women with GDM continued to have abnormal glucose levels after delivery. Compared with the women who reverted to normal, HOMA-IR was significantly higher in AGM. A multiple stepwise regression analysis revealed that age, the postpartum body mass index (BMI), low density lipoprotein-cholesterol (LDL-C), 2 h glucose load plasma glucose (2 h PG), triglycerides (TG), hemoglobin A1c (HbA1c), 1 h glucose load plasma insulin (INS) level, and 2 h INS level were independent risk factors for the development of insulin resistance after delivery. This study has identified a high prevalence of AGM after GDM. Insulin resistance appears to be the major contributor. Any treatment to reduce the postpartum BMI and lipids level may be beneficial to decrease insulin resistance.

[Exosomes and their roles in diabetes mellitus and its complications: from pathogenic, diagnostic and therapeutical perspectives].

Exosome is a kind of nanoscale-size extracellular vesicles secreted by the means of cell active stimulation with outer membrane structure of vacuoles corpuscle. It can carry and transfer a lot of biological molecules, such as DNA fragments, circular RNA (circRNA), messenger RNA (mRNA), microRNA (miRNA), functional proteins, transcription factors, etc., so as to achieve the goal of information transmission between cells. The relationship between exosomes and diabetes has received extensive attention in recent years. The exosomes play an important role in insulin sensitivity, glucose homeostasis and vascular endothelial function. This paper reviews the role of exosomes in the occurrence and development of diabetes and its complications, and discusses the role and prospect of exosomes as a target for diabetes treatment and its role in the diagnosis and treatment of diabetes.

Embedding ultrafine ZnSnO3 nanoparticles into reduced graphene oxide composites as high-performance electrodes for lithium ion batteries.

Ultrafine ZnSnO3 nanoparticles, with an average diameter of 45 nm, homogeneously grown on reduced graphene oxide (rGO) have been successfully fabricated via methods of low temperature coprecipitation, colloid electrostatic self-assembly, and hydrothermal treatment. The uniformly distributed ZnSnO3 nanocrystals could inhibit the restacking of rGO sheets. In turn, the existence of rGO could hinder the growth and aggregation of ZnSnO3 nanoparticles in the synthesis process, increase the conductivity of the composite, and buffer the volume expansion of the ZnSnO3 nanocrystals upon lithium ion insertion and extraction. The obtained ZnSnO3/rGO exhibited superior cycling stability with a discharge/charge capacity of 718/696 mA h g-1 after 100 cycles at a current density of 0.1 A g-1.

Comparison of serum concentrations of humanin in women with and without gestational diabetes mellitus.

Humanin (MT-RNR2) is an endogenous polypeptide that is involved in many diseases, including T2DM. Gestational diabetes mellitus (GDM) is defined as hyperglycemia during pregnancy. The aim of this study was to evaluate serum humanin levels in women with or without GDM and to elucidate possible correlations with anthropometric parameters, metabolic parameters and the incidence of GDM. Eighty-four women with GDM and 73 control women were enrolled in this study. The clinical and biochemical parameters of all subjects were determined. Serum humanin levels were measured by an ELISA. Serum humanin levels were significantly lower in women with GDM than in control women. Moreover, humanin levels were significantly negatively correlated with the presence of GDM, body weight, BMI at 24 weeks of gestation, TG, FPG, 1 hPG, 2 hPG, FINS, and HOMA-IR. In contrast, humanin levels were significantly positively correlated with FT3 and FT4. A binary logistic analysis showed that humanin levels were associated with the incidence of GDM. Additional follow-up studies are needed to highlight whether and how decreased humanin levels play an important role in GDM.

Gender Disparity in the Relationship between Prevalence of Thyroid Nodules and Metabolic Syndrome Components: The SHDC-CDPC Community-Based Study.

The study is aimed to investigate the pathogenesis underlying the increased prevalence of thyroid nodule (TN) in different levels of metabolic syndrome (MetS) components and analyze the relationships between TN and MetS components. A total of 6,798 subjects, including 2201 patients with TN, were enrolled in this study. Anthropometric, biochemical, thyroid ultrasonographic, and other metabolic parameters were all measured. There was obviously sexual difference in the prevalence of TN (males 26.0%, females 38.5%, resp.). The prevalence of TN in hyperuricemia (45.7% versus 37.4%, P = 0.001), NAFLD (41.2% versus 36.4%, P < 0.05), and MetS (41.4% versus 35.4%, P < 0.001) groups was significantly increased only in females. Insulin resistance [OR = 1.31 (1.15, 1.49)], MetS [OR = 1.18 (1.03, 1.35)], and diabetes [OR = 1.25 (1.06, 1.48)] were all independent risk factors for TN in total subjects, whereas, after stratified analysis of gender, MetS [OR = 1.29, (1.09, 1.53)] and diabetes [OR = 1.47, (1.17, 1.84)] are still strongly and independently associated with the higher risks of TN in female subjects, but not in males. Our results suggest that the components of MetS might associate with the higher risks of TN in women than in men, but further cohort study of this gender disparity in the association between TN and MetS is required.

Identification of a Novel Function of Adipocyte Plasma Membrane-Associated Protein (APMAP) in Gestational Diabetes Mellitus by Proteomic Analysis of Omental Adipose Tissue.

Gestational diabetes mellitus (GDM) is considered as an early stage of type 2 diabetes mellitus. In this study, we compared demographic and clinical data between six GDM subjects and six normal glucose tolerance (NGT; healthy controls) subjects and found that homeostasis model of assessment for insulin resistance index (HOMA-IR) increased in GDM. Many previous studies demonstrated that omental adipose tissue dysfunction could induce insulin resistance. Thus, to investigate the cause of insulin resistance in GDM, we used label-free proteomics to identify differentially expressed proteins in omental adipose tissues from GDM and NGT subjects (data are available via ProteomeXchange with identifier PXD003095). A total of 3528 proteins were identified, including 66 significantly changed proteins. Adipocyte plasma membrane-associated protein (APMAP, a.k.a. C20orf3), one of the differentially expressed proteins, was down-regulated in GDM omental adipose tissues. Furthermore, mature 3T3-L1 adipocytes were used to simulate omental adipocytes. The inhibition of APMAP expression by RNAi impaired insulin signaling and activated NFκB signaling in these adipocytes. Our study revealed that the down-regulation of APMAP in omental adipose tissue may play an important role in insulin resistance in the pathophysiology of GDM.

Rapamycin improves palmitate-induced ER stress/NF κ B pathways associated with stimulating autophagy in adipocytes.

Obesity-induced endoplasmic reticulum (ER) stress and inflammation lead to adipocytes dysfunction. Autophagy helps to adapt to cellular stress and involves in regulating innate inflammatory response. In present study, we examined the activity of rapamycin, a mTOR kinase inhibitor, against endoplasmic reticulum stress and inflammation in adipocytes. An in vitro model was used in which 3T3-L1 adipocytes were preloaded with palmitate (PA) to generate artificial hypertrophy mature adipocytes. Elevated autophagy flux and increased number of autophagosomes were observed in response to PA and rapamycin treatment. Rapamycin attenuated PA-induced PERK and IRE1-associated UPR pathways, evidenced by decreased protein levels of eIF2α phosphorylation, ATF4, CHOP, and JNK phosphorylation. Inhibiting autophagy with chloroquine (CQ) exacerbated these ER stress markers, indicating the role of autophagy in ameliorating ER stress. In addition, cotreatment of CQ abolished the anti-ER stress effects of rapamycin, which confirms the effect of rapamycin on ERs is autophagy-dependent. Furthermore, rapamycin decreased PA-induced nuclear translocation of NFκB P65 subunit, thereby NFκB-dependent inflammatory cytokines MCP-1 and IL-6 expression and secretion. In conclusion, rapamycin attenuated PA-induced ER stress/NFκB pathways to counterbalance adipocytes stress and inflammation. The beneficial of rapamycin in this context partly depends on autophagy. Stimulating autophagy may become a way to attenuate adipocytes dysfunction.

Effects of Glucagon-Like Peptide-1 Receptor Agonists on Gut Microbiota in Dehydroepiandrosterone-Induced Polycystic Ovary Syndrome Mice: Compared Evaluation of Liraglutide and Semaglutide Intervention.

Purpose: Polycystic ovary syndrome (PCOS) is a frequent cause of infertility in reproductive-age women. Our work aims to evaluate the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on gut microbiota, with metabolic parameters including body weight and the hormone profile in PCOS. Patients and Methods: Dehydroepiandrosterone (DHEA)-induced PCOS mice were established and then treated with two GLP-1RAs: liraglutide and novel form semaglutide for four weeks. Changes in body weight and metabolic parameters were measured. Fecal samples were collected and analyzed using metagenomic sequencing. Results: Liraglutide and semaglutide modulated both alpha and beta diversity of the gut microbiota in PCOS. Liraglutide increased the Bacillota-to-Bacteroidota ratio through up-regulating the abundance of butyrate-producing members of Bacillota like Lachnospiraceae. Moreover, liraglutide showed the ability to reverse the altered microbial composition and the disrupted microbiota functions caused by PCOS. Semaglutide increased the abundance of Helicobacter in PCOS mice (p < 0.01) which was the only bacteria found negatively correlated with body weight. Moreover, pathways involving porphyrin and flavonoids were increased after semaglutide intervention. Conclusion: Liraglutide and semaglutide improved reproductive and metabolic disorders by modulating the whole structure of gut microbiota in PCOS. The greater efficacy in weight loss compared with liraglutide observed after semaglutide intervention was positively related with Helicobacter. The study may provide new ideas in the treatment and the underlying mechanisms of GLP-1RAs to improve PCOS.

High-throughput single-cell assay for precise measurement of the intrinsic mechanical properties and shape characteristics of red blood cells.

The intrinsic physical and mechanical properties of red blood cells (RBCs), including their geometric and rheological characteristics, can undergo changes in various circulatory and metabolic diseases. However, clinical diagnosis using RBC biophysical phenotypes remains impractical due to the unique biconcave shape, remarkable deformability, and high heterogeneity within different subpopulations. Here, we combine the hydrodynamic mechanisms of fluid-cell interactions in micro circular tubes with a machine learning method to develop a relatively high-throughput microfluidic technology that can accurately measure the shear modulus of the membrane, viscosity, surface area, and volume of individual RBCs. The present method can detect the subtle changes of mechanical properties in various RBC components at continuum scales in response to different doses of cytoskeletal drugs. We also investigate the correlation between glycosylated hemoglobin and RBC mechanical properties. Our study develops a methodology that combines microfluidic technology and machine learning to explore the material properties of cells based on fluid-cell interactions. This approach holds promise in offering novel label-free single-cell-assay-based biophysical markers for RBCs, thereby enhancing the potential for more robust disease diagnosis.

Adaptive laboratory evolution of Naematelia aurantialba under high temperature for efficient production of exopolysaccharide.

Liquid fermentation could revolutionize mushroom polysaccharide production, but the low temperature constraint hampers the process. This study implemented adaptive laboratory evolution (ALE) to enhance the thermotolerance of Naematelia aurantialba strains and increase expolysaccharide production. After 75 ALE cycles at 30 °C, the adaptive strain surpassed the wild-type strain by 5 °C. In a 7.5 L fermentor at 30 °C, the ALE strain yielded 17 % more exopolysaccharide than the wild type strain at 25 °C. Although the exopolysaccharide synthesized by both strains shares a consistent monosaccharide composition, infrared spectrum, and glycosidic bond composition, the ALE strain's exopolysaccharide has a larger molecular weight. Furthermore, the ALE strain's exopolysaccharide exhibits superior cryoprotection performance compared to that produced by the original strain. The adapted strain demonstrated lower ROS levels and increased activity of antioxidant enzymes, indicating improved performance. Fatty acid profiling and transcriptomics revealed reconfiguration of carbohydrate metabolism, amino acid metabolism, and membrane lipid synthesis in thermophilic strains, maintaining cellular homeostasis and productivity. This study provides efficient strains and fermentation methods for high-temperature mushroom polysaccharide production, reducing energy consumption and costs.

Efficacy of cementless porous tantalum tibial components versus cemented tibial components in primary total knee arthroplasty: A meta-analysis.

BACKGROUND: Total knee arthroplasty involves the use of cemented tibial components for fixation. In recent years, cementless porous tantalum tibial components have been increasingly utilized. The aim of this meta-analysis was to compare the efficacy of cementless porous tantalum tibial components with traditional cemented tibial components in terms of postoperative outcomes following total knee arthroplasty. METHODS: Relevant literature was retrieved from Cochrane Library, PubMed, Embase, and Web of Science using the search terms "(trabecular metal OR Porous tantalum)" AND "knee" up to July 2023. The weighted mean difference with a 95% confidence interval was used as the effect size measure to evaluate the functional recovery of the knee joint, radiological analysis, complications, and implant revisions between cementless porous tantalum tibial components and traditional cemented tibial components after total knee arthroplasty. Review Manager 5.3 was utilized to conduct a comparative analysis of all included studies. RESULTS: Nine studies with a total of 1117 patients were included in this meta-analysis, consisting of 447 patients in the porous tantalum group and 670 patients in the cemented group. Radiological analysis demonstrated that the porous tantalum group had better outcomes than the cemented group (P < .05). The combined results for the 5-year and 10-year follow-ups, range of motion, Western Ontario and McMaster University Osteoarthritis Index, complications, and implant revisions showed no significant differences between the porous tantalum and cemented groups. CONCLUSION: The results of the 5-year and 10-year follow-ups indicate that the use of cementless porous tantalum tibial components is comparable to traditional cemented tibial components, with no significant advantages observed. However, at the 5-year follow-up, the porous tantalum group demonstrated a good bone density in the proximal tibia. Future studies with a larger sample size, long-term clinical follow-up, and radiological results are needed to verify the differences between the 2 implants.

Metabolomic profiling reveals decreased serum cysteine levels during gestational diabetes mellitus progression.

Gestational diabetes mellitus (GDM) is a pregnancy-related metabolic disorder associated with short-term and long-term adverse health outcomes, but its pathogenesis has not been clearly elucidated. Investigations of the dynamic changes in metabolomic markers in different trimesters may reveal the underlying pathophysiology of GDM progression. Therefore, in the present study, we analyzed the metabolic profiles of 75 women with GDM and 75 women with normal glucose tolerance (NGT) throughout the three trimesters. We found that the variation trends of 38 metabolites were significantly different during GDM development. Specifically, longitudinal analyses revealed that cysteine (Cys) levels significantly decreased over the course of GDM progression. Further study showed that Cys alleviated GDM in female mice at gestational day 14.5 possibly by inhibiting phosphoenolpyruvate carboxykinase to suppress hepatic gluconeogenesis. Taken together, these findings suggest that the Cys metabolic pathway might play a crucial role in GDM and that Cys supplementation represents a potential new treatment strategy for GDM patients.

In vitro digestion and fecal fermentation of basidiospore-derived exopolysaccharides from Naematelia aurantialba.

Mushroom polysaccharides exhibit numerous health-enhancing attributes that are intricately linked to the breakdown, assimilation, and exploitation of polysaccharides within the organism. Naematelia aurantialba polysaccharides (NAPS-A), highly prized polysaccharides derived from mushrooms, remain shrouded in uncertainty regarding their characteristics pertaining to gastrointestinal digestion and gut microbial fermentation. The study aimed to understand the digestion and fecal fermentation patterns of NAPS-A. After simulated digestion, NAPS-A's physicochemical properties remained unchanged. However, during in vitro fecal fermentation, indigestible NAPS-A underwent significant changes in various properties, such as reducing sugar, chemical composition, constituent monosaccharides, Molecular weight, apparent viscosity, FT-IR spectra, and microscopic morphology. Notably, NAPS-A was effectively utilized by the gut microbiota, with unchanged properties after digestion but altered after fermentation. It influenced gut microbe composition by increasing beneficial bacteria (Lactobacillus, Faecalibacterium, and Roseburia), lowering pH, and producing short-chain fatty acids. NAPS-A fermentation enriches carbohydrate, fatty acid, and amino acid metabolic pathways through PICRUSt prediction analysis. Overall, these findings emphasize NAPS-A's role in regulating gut bacteria and their metabolic functions, despite its challenging digestibility.

The effects of economic status on metabolic control in type 2 diabetes mellitus at 10 metabolic management centers in China.

OBJECTIVE: This study investigated the association of economic status with metabolic index control in type 2 diabetes mellitus (T2DM) patients. METHODS: In total, 37 454 T2DM patients from 10 National Metabolic Management Centers in China were recruited and categorized into two groups: a high-gross domestic product (GDP) group (n = 23 993) and a low-GDP group (n = 13 461). Sociodemographic characteristics, medical histories, and lifestyle factors were recorded. Logistic regression and interaction analysis were performed to evaluate the association of economic status and healthy lifestyle with metabolic control. RESULTS: Compared to the low-GDP group, there were fewer patients with glycated hemoglobin (HbA1c) levels ≥7% in the high-GDP group. Fewer patients with a high GDP had an abnormal metabolic state (HbA1c ≥ 7%, blood pressure [BP] ≥130/80 mm Hg, total cholesterol [TCH] ≥4.5 mmol/L or body mass index [BMI] ≥24 kg/m2 ). The risks of developing HbA1c ≥ 7% (odds ratios [OR] = 0.545 [95% CI: 0.515-0.577], p < .001), BP ≥ 130/80 mm Hg (OR = 0.808 [95% CI: 0.770-0.849], p < .001), BMI ≥ 24 kg/m2 (OR = 0.840 [95% CI: 0.799-0.884], p < .001), and an abnormal metabolic state (OR = 0.533 [95% CI: 0.444-0.636], p < .001) were significantly lower in the high-GDP group even after adjustment for confounding factors. Younger participants; those with a family history of diabetes, normal weight, and a physical activity level up to standard; and those who did not drink alcohol in the high-GDP group were predisposed to better glycemic levels. CONCLUSIONS: T2DM patients in economically developed regions had better metabolic control, especially glycemic control. A healthy lifestyle had an additive effect on achieving glycemic goals, even among high-GDP patients.

Emerging Schemes for Advancing 2D Material Photoconductive-Type Photodetectors.

By virtue of the widely tunable band structure, dangling-bond-free surface, gate electrostatic controllability, excellent flexibility, and high light transmittance, 2D layered materials have shown indisputable application prospects in the field of optoelectronic sensing. However, 2D materials commonly suffer from weak light absorption, limited carrier lifetime, and pronounced interfacial effects, which have led to the necessity for further improvement in the performance of 2D material photodetectors to make them fully competent for the numerous requirements of practical applications. In recent years, researchers have explored multifarious improvement methods for 2D material photodetectors from a variety of perspectives. To promote the further development and innovation of 2D material photodetectors, this review epitomizes the latest research progress in improving the performance of 2D material photodetectors, including improvement in crystalline quality, band engineering, interface passivation, light harvesting enhancement, channel depletion, channel shrinkage, and selective carrier trapping, with the focus on their underlying working mechanisms. In the end, the ongoing challenges in this burgeoning field are underscored, and potential strategies addressing them have been proposed. On the whole, this review sheds light on improving the performance of 2D material photodetectors in the upcoming future.

Effects of osteogenic growth peptide C-terminal pentapeptide and its analogue on bone remodeling in an osteoporosis rat model.

This study aimed to explore the effects of osteogenic growth peptide C-terminal pentapeptide (G36G), and its analog G48A on bone modeling in rats with ovariectomy-induced osteoporosis. Ovariectomized rats were administered PBS (OVX group), risedronate (RISE group), G36G combined with risedronate (36GRI group), G36G (G36G group), or G48A (G48A group). The sham-operation rats (SHAM group) were administered PBS. Serum osteocalcin and IGF-2 levels in the SHAM, OVX, G36G, G48A, and RISE groups were observably lower than the 36GRI group (P < 0.01) and the bone mineral density of the entire femur, distal metaphysis, and lumbar L1-L4 in the 36GRI group were notably increased (P < 0.05). The bending energy of the 36GRI group was prominently higher than the other groups (P < 0.05). Other features measured in the study that provided significant outcomes was the ratio of femora ash weight/dry weigh, parameters of trabecular bone volume (TBV)/total tissue volume, TBV/sponge bone volume, mean trabecular plate thickness, mean trabecular plate space, bone surface, parameters of sfract(s) and sfract(d), tetracycline-labeled, and osteoid surfaces. Bone loss in ovariectomized rats may be partially inhibited by G36G and G48A. A combination treatment with G36G and risedronate may be an effective intervention for osteoporosis.
