Using a DNA mini-barcode within the ITS region to identify toxic Amanita in mushroom poisoning cases.

Mushroom poisoning contributes significantly to global foodborne diseases and related fatalities. Amanita mushrooms frequently cause such poisonings; however, identifying these toxic species is challenging due to the unavailability of fresh and intact samples. It is often necessary to analyze residues, vomitus, or stomach extracts to obtain DNA sequences for the identification of species responsible for causing food poisoning. This usually proves challenging to obtain usable DNA sequences that can be analyzed using conventional molecular biology techniques. Therefore, this study aimed to develop a DNA mini-barcoding method for the identification of Amanita species. Following the evaluation and optimization of universal primers for DNA mini-barcoding in Amanita mushrooms, we found that the internal transcribed spacer (ITS) gene sequence primer ITS-a was the most suitable DNA barcode primer for identifying Amanita species. Forty-three Amanita samples were subsequently amplified and sequenced. The sequences obtained were analyzed for intra- and inter-species genetic distances, and a phylogenetic tree was constructed. The findings indicated that the designed primers had strong universality among the Amanita samples and could accurately identify the target gene fragment with a length of 290 bp. Notably, the DNA mini-barcode accurately identified the 43 Amanita samples, demonstrating high consistency with the conventional DNA barcode. Furthermore, it effectively identified DNA from digested samples. In summary, this DNA mini-barcode is a promising tool for detecting accidental ingestion of toxic Amanita mushrooms. It may be used as an optimal barcode for species identification and traceability in events of Amanita-induced mushroom poisoning. KEY POINTS: • Development of a DNA mini-barcoding method for Amanita species identification without fresh samples. • The ITS-a primer set was optimized for robust universality in Amanita samples. • The mini-barcode is suitable for screening toxic mushroom species in mushroom poisoning cases.

Cuticular competing endogenous RNAs regulate insecticide penetration and resistance in a major agricultural pest.

BACKGROUND: The continuously developing pesticide resistance is a great threat to agriculture and human health. Understanding the mechanisms of insecticide resistance is a key step in dealing with the phenomenon. Insect cuticle is recently documented to delay xenobiotic penetration which breaks the previous stereotype that cuticle is useless in insecticide resistance, while the underlying mechanism remains scarce. RESULTS: Here, we find the integument contributes over 40.0% to insecticide resistance via different insecticide delivery strategies in oriental fruit fly. A negative relationship exists between cuticle thickening and insecticide penetration in resistant/susceptible, also in field strains of oriental fruit fly which is a reason for integument-mediated resistance. Our investigations uncover a regulator of insecticide penetration that miR-994 mimic treatment causes cuticle thinning and increases susceptibility to malathion, whereas miR-994 inhibitor results in opposite phenotypes. The target of miR-994 is a most abundant cuticle protein (CPCFC) in resistant/susceptible integument expression profile, which possesses capability of chitin-binding and influences the cuticle thickness-mediated insecticide penetration. Our analyses find an upstream transcriptional regulatory signal of miR-994 cascade, long noncoding RNA (lnc19419), that indirectly upregulates CPCFC in cuticle of the resistant strain by sponging miR-994. Thus, we elucidate the mechanism of cuticular competing endogenous RNAs for regulating insecticide penetration and demonstrate it also exists in field strain of oriental fruit fly. CONCLUSIONS: We unveil a regulatory axis of lnc19419 ~ miR-994 ~ CPCFC on the cuticle thickness that leads to insecticide penetration resistance. These findings indicate that competing endogenous RNAs regulate insecticide resistance by modulating the cuticle thickness and provide insight into the resistance mechanism in insects.

The role of PIWIL4 and piRNAs in the development of choroidal neovascularization.

Wet age-related macular degeneration (wAMD) is the leading cause of blindness among the elderly in industrialized nations. Anti-vascular epidermal growth factor (VEGF) therapy via intravitreal injection is the most effective clinical treatment for wAMD due to high concentrations of VEGF that promote choroidal neovascularization. While PIWI proteins participate in various biological processes, their function in AMD remains unclear. In this study, we discovered that PIWIL4 expression is elevated in a laser-induced choroidal neovascularization (CNV) model and that it regulates angiogenesis in vitro and in vivo. Differentially expressed piwi-interacting RNAs (piRNAs) were identified in a CNV model and were shown to potentially regulate angiogenesis via bioinformatics analysis. PIWIL4 knockdown inhibits VEGF secretion and VEGFR2 phosphorylation. Overall, PIWIL4 may serve as a novel target to block pathological choroidal neovascularization, and the study of the PIWI-piRNAs pathway in wAMD highlights its broad function in somatic cells.

[Oblique Lumbar Interbody Fusion Combined With 4-Screw Fixation for Treating Two-Level Degenerative Lumbar Diseases:A Finite Element Study].

Objective To demonstrate the feasibility of oblique lumbar interbody fusion (OLIF) combined with 4-screw fixation for treating two-level lumbar degenerative diseases.Methods An intact finite element model of L3-S1 (M0) was constructed and validated.Then,we constructed the M1 model by simulating OLIF surgery at L3/4 and L4/5 segments on the M0 model.By attachment of posterior 4-screw or 6-screw fixation to the M1 model,three 4-screw fixation models (M2-M4) and one 6-screw fixation model (M5) were established.The segmental and overall range of motion (ROM) and the peak von Mises stresses of superior endplate,cage,and posterior screw-rod were investigated under each implanted condition.Results Under the motion modes of forward flexion,backward extension,bilateral (left and right) flexion,and left and right rotation,the L3/4 ROM of M2 model and L4/5 ROM of M3 model increased,while the L3/4 and L4/5 ROM of M4 and M5 models significantly decreased compared with those of M1 model.Under all motion modes,the L4 superior endplate in M2 model and the L5 superior endplate in M3 model showed the maximum peak von Mises stress,and the peak von Mises stresses of L4 and L5 superior endplates in M4 and M5 models were close.The L3/4 cage in M2 model and the L4/5 cage in M3 model showcased the largest peak von Mises stress,and the peak von Mises stresses of cages in M4 and M5 models were close.The peak stresses of internal fixation in M2-M5 models were close.Conclusion Four-screw fixation can replace 6-screw fixation in the OLIF surgery for treating two-level degenerative lumbar diseases.

Advancing treatment strategies for posterior malleolar malunion: The ankle dislocation method.

BACKGROUND: This study aimed to assess the radiological and clinical outcomes of treatment using the ankle dislocation method for posterior malleolar malunion. METHOD: Thirty-one patients with posterior malleolar malunion who underwent treatment using the ankle dislocation method from May 2015 to October 2021 were retrospectively analyzed. Key outcome measures were radiographic parameters (articular step-off, tibiofibular clear space, fibular length, tibial lateral surface angle, and ankle osteoarthritis), clinical scores (American Orthopaedic Foot and Ankle Society ankle-hindfoot scale and Visual Analogue Scale), and patient satisfaction rate. RESULT: Preoperative computed tomography revealed that Bartoní cek types 3 and 4 accounted for 64.5 % (n = 20) of total cases. Most posterior malleolar malunions were accompanied by depressed intercalary fragments (61.2 % [n = 19]). At the final follow-up, radiographic parameters and clinical scores showed significant improvements postoperatively (P < 0.05), with a high patient satisfaction rate of 77.4 %. Subgroup analysis revealed that the posterior malleolar fracture morphology significantly affected postoperative pain, particularly in more complex fractures (P < 0.001). CONCLUSION: The ankle dislocation method effectively exposes the distal tibial articular surface and facilitates the anatomical restoration of joint congruity under direct vision. This approach substantially improves the clinical and imaging outcomes in patients with complex posterior malleolar malunion. LEVELS OF EVIDENCE: Level IV, retrospective case series.

Catalytic Asymmetric P-H Insertion Reactions.

Albeit notable endeavors in enantioselective carbene insertion into X-H bonds (X = C, O, N, S, Si, B), the catalytic asymmetric P-H insertion reactions still stand for a long-lasting challenge. By merging transition-metal catalysis with organocatalysis, we achieve a scalable enantioselective P-H insertion transformation between diazo pyrazoleamides and H-phosphine oxides that upon subsequent reduction delivers a wide variety of optically active ß-hydroxyl phosphine oxides in good yields with high enantioselectivity. The achiral copper catalyst fosters the carbenoid insertion into the P-H bond, while the chiral cinchona alkaloid-derived organocatalyst controls the subsequent enantioselective outcome. Density functional theory (DFT) calculations further reveal that the copper catalyst chelates to the organocatalyst, enhances its acidity, and accordingly promotes the enantioselective proton transfer. Our work showcases the potential of combining transition-metal catalysis with organocatalysis to realize elusive asymmetric reactions.

Targeting FSCN1 with an oral small-molecule inhibitor for treating ocular neovascularization.

BACKGROUND: Ocular neovascularization is a leading cause of blindness and visual impairment. While intravitreal anti-VEGF agents can be effective, they do have several drawbacks, such as endophthalmitis and drug resistance. Additional studies are necessary to explore alternative therapeutic targets. METHODS: Bioinformatics analysis and quantitative RT-PCR were used to detect and verify the FSCN1 expression levels in oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV) mice model. Transwell, wound scratching, tube formation, three-dimensional bead sprouting assay, rhodamine-phalloidin staining, Isolectin B4 staining and immunofluorescent staining were conducted to detect the role of FSCN1 and its oral inhibitor NP-G2-044 in vivo and vitro. HPLC-MS/MS analysis, cell apoptosis assay, MTT assay, H&E and tunnel staining, visual electrophysiology testing, visual cliff test and light/dark transition test were conducted to assess the pharmacokinetic and security of NP-G2-044 in vivo and vitro. Co-Immunoprecipitation, qRT-PCR and western blot were conducted to reveal the mechanism of FSCN1 and NP-G2-044 mediated pathological ocular neovascularization. RESULTS: We discovered that Fascin homologue 1 (FSCN1) is vital for angiogenesis both in vitro and in vivo, and that it is highly expressed in oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV). We found that NP-G2-044, a small-molecule inhibitor of FSCN1 with oral activity, can impede the sprouting, migration, and filopodia formation of cultured endothelial cells. Oral NP-G2-044 can effectively and safely curb the development of OIR and CNV, and increase efficacy while overcoming anti-VEGF resistance in combination with intravitreal aflibercept (Eylea) injection. CONCLUSION: Collectively, FSCN1 inhibition could serve as a promising therapeutic approach to block ocular neovascularization.

Hypoxia-induced AFAP1L1 regulates pathological neovascularization via the YAP-DLL4-NOTCH axis.

BACKGROUND: Pathological neovascularization plays a pivotal role in the onset and progression of tumors and neovascular eye diseases. Despite notable advancements in the development of anti-angiogenic medications that target vascular endothelial growth factor (VEGF) and its receptors (VEGFRs), the occurrence of adverse reactions and drug resistance has somewhat impeded the widespread application of these drugs. Therefore, additional investigations are warranted to explore alternative therapeutic targets. In recent years, owing to the swift advancement of high-throughput sequencing technology, pan-cancer analysis and single-cell sequencing analysis have emerged as pivotal methodologies and focal areas within the domain of omics research, which is of great significance for us to find potential targets related to the regulation of pathological neovascularization. METHODS: Pan-cancer analysis and scRNA-seq data analysis were employed to forecast the association between Actin filament-associated protein 1 like 1 (AFAP1L1) and the development of tumors and endothelial cells. Tumor xenograft model and ocular pathological neovascularization model were constructed as well as Isolectin B4 (IsoB4) staining and immunofluorescence staining were used to assess the effects of AFAP1L1 on the progression of neoplasms and neovascular eye diseases in vivo. Transwell assay, wound scratch assay, tube forming assay, three-dimensional germination assay, and rhodamine-phalloidin staining were used to evaluate the impact of AFAP1L1 on human umbilical vein endothelial cells (HUVECs) function in vitro; Dual luciferase reporting, qRT-PCR and western blot were used to investigate the upstream and downstream mechanisms of pathological neovascularization mediated by AFAP1L1. RESULTS: Our investigation revealed that AFAP1L1 plays a crucial role in promoting the development of various tumors and demonstrates a strong correlation with endothelial cells. Targeted suppression of AFAP1L1 specifically in endothelial cells in vivo proves effective in inhibiting tumor formation and ocular pathological neovascularization. Mechanistically, AFAP1L1 functions as a hypoxia-related regulatory protein that can be activated by HIF-1α. In vitro experiments demonstrated that reducing AFAP1L1 levels can reverse hypoxia-induced excessive angiogenic capacity in HUVECs. The principal mechanism of angiogenesis inhibition entails the regulation of tip cell behavior through the YAP-DLL4-NOTCH axis. CONCLUSION: In conclusion, AFAP1L1, a newly identified hypoxia-related regulatory protein, can be activated by HIF-1α. Inhibiting AFAP1L1 results in the inhibition of angiogenesis by suppressing the germination of endothelial tip cells through the YAP-DLL4-NOTCH axis. This presents a promising therapeutic target to halt the progression of tumors and neovascular eye disease.

A Systematic Review and Meta-Analysis of the Association between Residual Shunts after Patent Foramen Ovale Closure and Long-Term Cerebrovascular Events.

BACKGROUND: The association between a patent foramen ovale (PFO) and cryptogenic stroke (CS) is well established, and the benefits of PFO closure are clearly recognized. This study aimed to investigate the presence of a residual shunt in patients who have experienced cryptogenic cerebrovascular events following a PFO closure. METHODS: Two researchers systematically searched the PubMed and Embase online database for pertinent clinical studies published between January 2000 and July 2021 concerning the recurrence of cerebrovascular events after PFO closures. RESULTS: Upon screening an initial list of 2,342 articles, six studies were identified, involving 2,083 patients. Overall, the analysis indicated a marked difference in the recurrence of cerebrovascular events in 8.89% of residual shunt (RS) cases compared to only 2.90% of non-RS cases. The summary odds ratio was 3.484 (95% confidence interval, 2.169-5.596), which suggested that RS may be a risk factor for recurrent cerebrovascular events in patients that experienced PFO-related cerebrovascular events within 6 months after PFO closure surgery. CONCLUSIONS: The presence of RS significantly increases the risk of recurrent cerebrovascular events in patients with clinical PFO closure.

Objective: To analyze the effect of comprehensive nursing intervention on the efficacy of spleen aminopeptide combined with aerosol inhalation in the treatment of pediatric pneumonia. Methods: This is a retrospective study. Eighty children with pneumonia admitted to Baoding children's Hospital from March 2020 to March 2021 were included and randomly divided into two groups. Children in the control group received routine treatment and nursing measures, while those in the experimental group received comprehensive nursing intervention on the basis of routine treatment in the control group. The differences in clinical effect, symptom improvement time, nursing quality score and satisfaction score between the two groups were compared and analyzed. Results: The efficacy of the experimental group was significantly higher than that of the control group (p=0.02). After comprehensive nursing intervention, the cough disappearance time, body temperature recovery time, pulmonary rales disappearance time and hospitalization time in the experimental group were significantly shorter than those in the control group, with statistically significant differences (p<0.05). The scores of nursing quality such as health guidance, nursing operation, and medication management in the experimental group were higher than those in the control group, with significant differences in the data comparison between the groups (p<0.05). The satisfaction of the experimental group was 100%, which was higher than 90% of the control group, with a statistically significant difference (p=0.04). Conclusion: Comprehensive nursing intervention boasts various significant effects in the treatment of pediatric pneumonia, such as rapid amelioration of the condition, improvement of efficacy, and enhancement of nursing quality and satisfaction.

LncRNA-599547 contributes the inductive property of dermal papilla cells in cashmere goat through miR-15b-5p/Wnt10b axis.

The lncRNA-599547 (619-nt in length) is identified in secondary hair follicle (SHF) of cashmere goat, but its functional roles in regulating the inductive property of dermal papilla cells (DPCs) remains unknown. We found that lncRNA-599547 had significantly higher expression in dermal papilla of cashmere goat SHF at anagen than its counterpart at telogen. The overexpression of lncRNA-599547 led to a significant increase of ALP and LEF1 expression in DPCs (p < 0.05), whereas, the siLncRNA-1 mediated silencing of lncRNA-599547 significantly down-regulated the expression of ALP and LEF1 in DPCs (p < 0.05). Based on biotin-labeled RNA pull-down assay, we found that lncRNA-599547 directly interacted with chi-miR-15b-5p in DPCs. Based on both overexpression and silencing analysis of lncRNA-599547, our results indicate that lncRNA-599547 promotes the expression of Wnt10b in DPCs but without modulating its promoter methylation level. Using the mRNA-3'UTR fragments of goat Wnt10b containing the predicted binding sites of chi-miR-15b-5p in Dual-luciferase Reporter Assays, we show that lncRNA-599547 modulates the expression of Wnt10b at the chi-miR-15b-5p mediated post-transcriptional level. Taken together, our results indicate that lncRNA-599547 sponges miR-15b-5p to positively regulate the expression of Wnt10 gene, and thereby contributes the inductive property of DPCs in cashmere goat.

Therapeutic effect of the sulforaphane derivative JY4 on ulcerative colitis through the NF-κB-p65 pathway.

The efficacy of the sulforaphane derivative JY4 was evaluated in acute and chronic mouse models of ulcerative colitis induced by dextran sodium sulfate. Oral administration of JY4 led to significant improvements in symptoms, with recovery of body weight and colorectal length, together with reduced diarrhoea, bloody stools, ulceration of colonic tissue and infiltration of inflammatory cells. The oral bioavailability of JY4, determined by comparing oral dosing with injection into the tail vein, was 5.67%, which was comply with the idea in the intestinal function. Using a dual-luciferase reporter assay, immunofluorescence studies, western blot analysis and immunohistochemical staining, JY4 was shown to significant interfere with the NF-κB-p65 signaling pathway. By preventing the activation of NF-κB-p65, JY4 inhibited the overexpression of downstream inflammatory factors, thereby exerting an anti-inflammatory effect on the intestinal tract. This study thus provides a promising candidate drug, and a new concept for the treatment of ulcerative colitis.

[Normalized diagnosis and treatment of small penis: Advances in studies].

Small penis is abnormal development of the male external genitalia with unknown etiology. It is closely related to abnormal endocrine or pubertal development, chromosomal or genetic abnormalities. Pubertal growth retardation and secondary hypogonadism are commonly complicated by small penis or small testis; primary hypogonadal lesion develops in the testis; testosterone deficiency often results in small penis and short stature; sexual dysfunction and male infertility tend to occur in adult men. Attention should be paid to the four aspects concerning the clinically standardized diagnosis and treatment of small penis, namely, accurate measurement of the stretched penile length, active screening of possible causes, diagnosis and differential diagnosis, and active and effective clinical interventions for the purpose of increasing the penile length and improving the prognosis, patient's quality of life, and natural pregnancy rate.

Biocatalytic Enantioselective ß-Hydroxylation of Unactivated C-H Bonds in Aliphatic Carboxylic Acids.

Catalytic selective hydroxylation of unactivated aliphatic (sp3 ) C-H bonds without a directing group represents a formidable task for synthetic chemists. Through directed evolution of P450BSß hydroxylase, we realize oxyfunctionalization of unactivated C-H bonds in a broad spectrum of aliphatic carboxylic acids with varied chain lengths, functional groups and (hetero-)aromatic moieties in a highly chemo-, regio- and enantioselective fashion (>30 examples, Cß/Cα>20 : 1, >99 % ee). The X-ray structure of the evolved variant, P450BSß -L78I/Q85H/G290I, in complex with palmitic acid well rationalizes the experimentally observed regio- and enantioselectivity, and also reveals a reduced catalytic pocket volume that accounts for the increased reactivity with smaller substrates. This work showcases the potential of employing a biocatalyst to enable a chemical transformation that is particularly challenging by chemical methods.

Impact of chronic outward force on arterial responses of proximal and distal of long superficial femoral artery stent.

BACKGROUND: Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR). This study aimed to investigate the impact of COF of oversizing SENS on ISR of SFA. METHODS: In patients with implanted SENS in SFA, intimal hyperplasia especially between proximal segment and distal segment was evaluated by quantitative angiography, and the impact of COF on mid-term angiographic outcomes was investigated. In addition, porcine model with implanted SENS was used to evaluate the impact of COF on angiographic and histopathologic outcomes at 1 month. Excised stented arteries were evaluated by histopathologic analysis. RESULTS: We analyzed 65 SENS in 61 patients with follow-up angiography at 6 months to 1 year. The baseline diameter was 6.8 ± 0.71 mm and length were 97.0 ± 33.8 mm for the SENS. The ratio of the diameter of the stent to the reference vessel was 1.3 ± 0.24 at the proximal portion and 1.53 ± 0.27 at the distal portion (P < 0.001). In the long SFA stent, stent-to-vessel ratio was significantly higher in the distal stent than in the proximal stent (1.3 ± 0.2 vs. 1.55 ± 0.25, P = 0.001). ISR incidence was higher at the distal stent (37.3% vs 52.6%, P = 0.029). All 11 pigs survived for 4 weeks after SENS implantation. The vessel diameter was 4.04 ± 0.40 mm (control group) vs 4.45 ± 0.63 mm (oversized group), and the implanted stent diameter was 5.27 ± 0.46 mm vs. 7.18 ± 0.4 mm (P = 0.001). The stent-to-vessel diameter ratio was 1.31 ± 0.12 versus 1.63 ± 0.20 (P < 0.001). After 4 weeks, restenosis % was 29.5 ± 12.9% versus 46.8 ± 21.5% (P = 0.016). The neointimal area was 5.37 ± 1.15 mm2 vs. 8.53 ± 5.18 mm2 (P = 0.05). The restenosis % was 39.34 ± 8.53% versus 63.97 ± 17.1% (P = 0.001). CONCLUSIONS: COF is an important cause of restenosis in the distal portion of the SFA stent. Optimal sizing of the SFA stent is important to reduce the incidence of restenosis. Therefore, COF was an important factor of restenosis following distal SFA stenting.

LncRNA-MEG3 Regulates the Inflammatory Responses and Apoptosis in Porcine Alveolar Macrophages Infected with Haemophilus parasuis Through Modulating the miR-210/TLR4 Axis.

Haemophilus parasuis (H. parasuis, HPS) can elicit serious inflammatory responses and cause enormous economic loss to swine industry worldwide. However, the factors responsible for systemic infection and inflammatory responses of HPS have not yet been fully clarified. In this study, we found that lncRNA-MEG3 was significantly up-regulated in porcine alveolar macrophages (PAMs) infected with HPS. The gain- and loss-of-function analysis confirmed that lncRNA-MEG3 participated in the inflammatory responses and apoptosis in HPS-infected PAMs, which was assessed via several inflammatory cytokine genes (TNF-α, IL-1ß, and IL-6) and apoptotic factors (Bcl-2, Bax, and C-caspase-3). Based on biotin-labeled RNA pull-down assay, we found that lncRNA-MEG3 bound with miR-210 in HPS-infected PAMs. Based on both overexpression and knockdown analysis of lncRNA-MEG3, our results indicated that lncRNA-MEG3 promoted the expression of TLR4 in HPS-infected PAMs. Using dual-luciferase reporter assays, we showed that lncRNA-MEG3 positively regulated the expression of TLR4 gene in HPS-infected PAMs through miR-210 pathway. Taken together, our results indicated that lncRNA-MEG3 participated in the inflammatory responses and apoptosis in HPS-infected PAMs through modulating the miR-210/TLR4 axis. The results from this investigation provided significant information for a novel target to control HPS infection in swine.

Identification and molecular analysis of cashmere goat lncRNAs reveal their integrated regulatory network and potential roles in secondary hair follicle.

Long non-coding RNAs (lncRNAs) is a class of eukaryotic transcripts with length of more than 200 bp. They contribute to the regulation of gene expressions involved in multiple processes including the skin cell proliferation, differentiation, and reconstruction of the secondary hair follicles (SHFs). In this study, firstly, we identified 16 putative lncRNAs from SHFs of cashmere goat based on the EST sequences from NCBI database. Secondly, we investigated their transcriptional pattern in SHFs of cashmere goat, and constructed their ceRNA regulatory networks. The RT-qPCR results showed four lncRNAs (lncRNA-475074, -052149, -052140, and -051789) were significantly up-regulated, and nine lncRNAs (lncRNA-711032, -475083, -475070, -052139, -052127, -052037, -051903, -051847, and -051804) were significantly down-regulatd in anagen SHFs of cashmere goat. CeRNA networks analysis revealed complex interactional relationship among lncRNAs, miRNAs and mRNAs. Further, the KEGG pathway enrichment was performed for the potential target genes of the identified lncRNAs based on bioinformatics technique, and the results indicated that differentially expressed lncRNAs directly or indirectly might regulate potential target genes. Our results from this study will provide a significant information for further exploring the functions and possible mechanisms of the identified lncRNAs in SHFs of cashmere goat.

Correlation analysis of candidate gene SNP for high-yield in Liaoning cashmere goats with litter size and cashmere performance.

This study was designed to identify the relationship of four genes (GDF9, BMPR-IB, FecB and ESR) polymorphisms in the 3'UTR region with litter size and cashmere performance of Liaoning cashmere goats (LCG, n = 1140). The ESR C463T and T575G loci of LCG were genotyped. The results of correlation analysis showed that five effective single nucleotide polymorphisms (SNPs) loci (C47T, C94T, C299T, C463T and T575G) were found in the four genes. The lambing number of CC and CT genotypic individuals at FecB C94T locus was significantly higher than that of TT genotypic individuals (45.7 and 46.8%, respectively); the lambing number of CC genotypic individuals at ESR C463T locus was significantly higher than that of CT, TT genotypic individuals (9 and 15%, respectively); There was a positive correlation between CC genotype at C463T locus and cashmere fineness. In this study, the relationship between FecB C94T and ESR C463T loci C alleles and lambing number in LCG was preliminarily revealed. These results further confirmed that FecB and ESR genes may be significantly correlated with high fecundity of LCG.

Ketogenic diet in women with polycystic ovary syndrome and liver dysfunction who are obese: A randomized, open-label, parallel-group, controlled pilot trial.

AIM: To evaluate the effect of a ketogenic diet (KD) in women with polycystic ovary syndrome (PCOS) and liver dysfunction who were obese. METHODS: Women with PCOS and liver dysfunction who were obese were enrolled in this prospective, open-label, parallel-group, controlled pilot trial, and randomly received KD (KD group) or conventional pharmacological treatment (Essentiale plus Yasmin, control group) in a 1:1 ratio for 12 weeks. The primary endpoint was the liver function markers. Secondary endpoints included the menstrual cycle, anthropometric characteristics, body composition, hormonal levels, and metabolic biomarkers. RESULTS: Of the 20 eligible participants enrolled, 18 participants completed the study. The KD group reported a significant reduction in anthropometric characteristics and body composition from baseline to week 12 (all p < 0.05). In addition, there were significant reductions in menstrual cycle, plasma estradiol, and progesterone levels in two groups (all p < 0.05), but no significant between-group difference was observed. KD significantly reduced the liver function markers compared with control group (p < 0.05). The signs of fatty liver disappeared in six out of seven fatty liver participants in KD group after 12 weeks of intervention, while only one of 10 fatty liver participants in control group disappeared. CONCLUSIONS: In addition to improving the menstrual cycle, KD had the additional benefits of reducing blood glucose and body weight, improving liver function, and treating fatty liver compared to traditional pharmacological treatment in women with PCOS and liver dysfunction who were obese.

Enhanced Electrochemical Performance of Aprotic Li-CO2 Batteries with a Ruthenium-Complex-Based Mobile Catalyst.

Li-CO2 batteries are regarded as next-generation high-energy-density electrochemical devices. However, the greatest challenge arises from the formation of the discharge product, Li2 CO3 , which would accumulate and deactivate heterogenous catalysts to cause huge polarization. Herein, Ru(bpy)3 Cl2 was employed as a solution-phase catalyst for Li-CO2 batteries and proved to be the most effective one screened so far. Spectroscopy and electrochemical analyses elucidate that the RuII center could interact with both CO2 and amorphous Li2 C2 O4 intermediate, thus promoting electroreduction process and delaying carbonate transformation. As a result, the charge potential is reduced to 3.86 V and over 60 discharge/charge cycles are achieved with a fixed capacity of 1000 mAh g-1 at a current density of 300 mA g-1 . Our work provides a new avenue to improve the electrochemical performance of Li-CO2 batteries with efficient mobile catalysts.
