8 ± 1.5 mM). The remarkable activity of Inu-ISO3 on linear and branched inulin spotlights this enzyme as a potential player in the treatment of agricultural residua for the generation of added-value products.This study assessed ankle kinematics, surface electromyography, and center-of-pressure (COP) progression relative to the medial border of the foot during a side-cutting task in individuals with and without chronic ankle instability (CAI). Thirty participants (CAI = 15; Controls = 15) performed a side-cutting task on a force platform while 3-dimentional ankle kinematics, COP position, and surface electromyography from the tibialis anterior, medial gastrocnemius, fibularis longus, fibularis brevis, vastus medialis, and semitendinosus were recorded on the testing leg. Ankle kinematics, root-mean-square muscle activity and COP position relative to the medial boarder of the foot were compared between CAI and healthy controls (p less then 0.05). Significantly greater ankle internal rotation from 35-54% of the stance phase (p = 0.032) was found for the CAI group compared to controls. Furthermore, significantly greater tibialis anterior muscle activity from 86-94% of the stance phase (p = 0.022) and a more medial COP position from 81-100% (p less then 0.05) and of the stance phase was also observed in the CAI group. Less lateral COP progression and increased tibialis anterior activation in the CAI group could reflect a protective movement strategy during anticipated side-cutting to avoid recurrent injury. However, greater ankle internal rotation during mid-stance highlights a potential 'giving way' mechanism in individuals with CAI.Feline bocavirus-1 (FBoV-1) was first discovered in Hong Kong in 2012, and studies have indicated that the virus may cause feline hemorrhagic enteritis. Currently, there is a lack of an effective and quantitative method for FBoV-1 detection. In this study, a TaqMan-based quantitative real-time PCR (qPCR) for FBoV-1 detection was established. read more Primers and probes were designed to target the conserved region of the FBoV-1 NS1 gene. The sensitivity analysis indicated that the minimum detection limit was 4.57 × 101 copies/μL. The specificity test revealed no cross-reaction with seven other common feline viruses, including the same species-FBoV-2 and FBoV-3. The sensitivity of this method was 100 times higher than that of conventional PCR (cPCR). The established method showed good repeatability, with the intra-assay and inter-assay coefficients of variation of 0.18%-1.00% and 0.27%-0.45%, respectively. Furthermore, the analysis of feline feces revealed that the detection rate by qPCR was 7.0% (9/128), whereas that by cPCR was 4.7% (6/128). In conclusion, the established qPCR assay can quantitatively detect FBoV-1 with a high sensitivity, high specificity, and good reproducibility, making it a promising technique for the clinical detection of and basic and epidemiological research on FBoV-1.
Breast cancer is a type of cancer with a high incidence and mortality rate worldwide. Change in epigenetic mechanisms enhances cancer cell progression. Histon deacetylase 2 (HDAC2) was found to act as a potential oncogene in different malignancies. For better understanding the mechanisms related to breast cancer development, we investigated the role of HDAC2 in breast cancer and the inhibitory effect of miR-646 on this oncogene.

A total of thirty cancerous tissues and 30 adjacent non-cancerous specimens and also three breast cancer cell lines were enrolled in the study. Quantitative reverse transcriptase PCR (qRT-PCR) was employed to detect the HDAC2 and miR-646 expression level in the studied samples. The biological roles of HDAC2 and miR-646 were investigated through manipulating the expression level of HDAC2 or miR-646 in breast cancer cells. Finally, we evaluated whether the HDAC2 is a direct target for miR-646.

In this study, we found HDAC2 is significantly upregulated in cancerous specimens and cell lines compared to non-cancerous tissues and normal cell line. On the other hand, miR-646 expression was decreased in clinical specimens and breast cancer cells compared to non-cancerous samples. Knocking out of the HDAC2 and overexpression of miR-646 inhibited breast cancer cell growth but promoted cell death, while untreated groups showed inverse results. Furthermore, we showed that in the breast cancer cells, miR-646 regulates the progression and proliferation by suppressing HDAC2.

Taken together, our study identified a miR-646/HDAC2 regulatory function in the breast cancer development and introduced a therapeutically target for breast cancer.

Excessive mitochondrial fission was observed in diabetic kidney disease (DKD). Phosphoglycerate mutase family member 5 (PGAM5) plays an important role in mitochondrial fission by dephosphorylating the dynamin-related protein 1 at Ser637 (DRP1S637). Whether PGAM5 participates in the mitochondrial fission in diabetic renal tubular injury is unknown. Clinical trials have observed encouraging effect of Sodium-glucose cotransporter 2 (SGLT2) inhibitors on DKD though the underling mechanisms remain unclear.

We used KK-Ay mice as diabetic model and Empagliflozin (Empa) were administrated by oral gavage. The mitochondrial fission and the expressions of phosphorylated AMP-activated protein kinase (p-AMPK), specificityprotein1 (SP1), PGAM5 and DRP1S637 were tested. We also examined these changes in HK2 cells that cultured in normal glucose (NG), high glucose (HG) and high glucose+Empa (HG + Empa) environment. Then we verified our deduction using AMPK activator (5-aminoimidazole-4-carboximide Riboside, AICAR), inhibitor (Compound C), si-SP1 and si-PGAM5. Lastly, we testified the interaction between SP1 and the PGAM5promotor by CHIP assay.

The mitochondrial fission and the expression of SP1, PGAM5 increased and the expression of p-AMPK, DRP1S637 decreased in diabetic or HG environment. These changes were all reversed in Empa or AICAR treated groups. These reversal effects of Empa could be diminished by Compound C. Either si-SP1 or si-PGAM5 could alleviate the mitochondrial fission without affection on AMPK phosphorylation. Finally, the CHIP assay confirmed the interaction between SP1 and the PGAM5 promotor.

The PGAM5 aggravated the development of diabetic renal tubular injury and the Empa could improve the DKD by alleviating mitochondrial fission via AMPK/SP1/PGAM5 pathway.
