Activity

Expression levels of p-Akt and Akt in the LY294002 group were significantly lower than in the control group (all P less then 0.01). Also, the expression of p-Akt in the 740Y-P group was significantly higher than that in the control group (p less then 0.05). The proliferative activity of EOS, expression of EPO and p-Akt, and the number of migrated cells in the WT EOS group were higher than those in CCR3-/- EOS group (all P less then 0.05). After adding eotaxin, the WT EOS group was higher than the other three groups (all P less then 0.05). Mechanistically, CCR3-/- inhibited EOS’s proliferation, migration, and degranulation by downregulating PI3K/Akt pathway. This data suggests that the knockout of the CCR3 gene in bone marrow cells may inhibit the function of EOS by downregulating the PI3K/Akt pathway, thereby affecting AR; thus, the CCR3 gene may be a target gene for AR therapy.Tubulin-associated unit (tau) has been associated with more than 25 neurological disorders-the so-called tauopathies. Hence, finding a novel therapeutic agent targeting tau to halt the progression of diseases has been of interest. Alzheimer’s disease (AD) and progressive supranuclear palsy (PSP) are the most studied tauopathies. AD is characterized by two cardinal pathological mechanisms amyloid β (Aβ) plaques and neurofibrillary tangles (NFTs), leading to atrophy of the brain. Over the last few years, attention has been on NFTs composed of the hyperphosphorylated microtubule-associated protein tau. Tau contributes to the synaptic plasticity of axons; hyperphosphorylated and aggregated tau have been shown to increase the likelihood of cognitive impairments. PSP is also associated with tau accumulation in NFTs and neuropil threads, making this condition a candidate for tau-targeted therapies. Many tau-targeting therapies have been developed, and clinical trials are being conducted. Tau-targeting drugs are classified into four subgroups based on the pathological target tau phosphorylation inhibitors, stabilizers of microtubules, enhancing tau clearance, and tau aggregation inhibitors. On the other hand, the desired specificity and sensitivity of tau immunotherapy agents without interrupting normal proteome are the fundamental point of tremendous attention. Starting with animal studies of these therapies to clinical trials, both are divided into passive and active immunotherapies, while passive immunotherapies are the method of desire. Targeting aggregation and phosphorylation sites of tau is the chief target of therapies. This article reviews the latest animal and clinical studies of tau-based immunotherapies and tau-targeted drugs for AD and PSP.

A rectus femoris transfer (RFT) surgery with and without a hamstring lengthening (HSL) is used to treat stiff-knee gait in children with cerebral palsy (CP). While current literature has reported that a RFT surgery improves the kinematics at the knee, little is known about the kinematic changes at the hip.

Does a RFT surgery change hip joint kinematics in children with CP?

This retrospective study included children (<18 years old) diagnosed with CP, who underwent a RFT procedure, and who were seen at our institution’s accredited clinical motion laboratory. Patients with both pre- and post-operative gait analysis were identified and comparison between those analyses were performed to identify kinematic differences at the hip and knee. A total of 66 legs from 46 children (mean age 11.1±3.6) met the inclusion criteria.

Overall results revealed that a RFT did not change kinematics at the hip [p>0.05], however, a RFT did increase the maximum knee flexion during the swing period [Mean Difference Post hip kinematics in children with CP.

Pain interference, fatigue, and impaired physical function are common features of idiopathic inflammatory myopathies (IIM). The objective of this study was to evaluate the construct validity and test-retest reliability of the Patient Reported Outcome Information System (PROMIS) Pain Interference 6av1.0, Fatigue 7av1.0, and Physical Function 8bv2.0 instruments.

Patient-Reported Outcome Measures (PROMs) were deployed to adult IIM patients from OMERACT Myositis Working Group (MWG) international clinic sites via two online surveys (2019, 2021). Internal consistency of each PROM was analyzed by Cronbach’s α. Construct validity was determined by a priori hypotheses generated by the MWG with >75% agreement for each hypothesis and calculated with Pearson correlations. Test-retest reliability was assessed using intraclass correlation coefficient with PROMIS instruments administered at time zero and 7 days.

Surveys were sent to 368 participants in total; participants who completed each questionnaire varied (n=ents with IIM. Internal consistency of these instruments was excellent. A ceiling effect was noted in the Pain Interference instrument.The disorder of amino acid metabolism and the abuse of small molecule drugs pose serious threats to public health. However, due to the limitations of existing detection technologies in sensing cinnamaldehyde (CAL) and l-Arginine/l-Lysine (l-Arg/l-Lys), there is an urgent need to develop new sensing strategies to meet the severe challenges currently facing. Herein, nitrogen-doped carbon dots (N-CDs) were developed using a simple one-pot hydrothermal carbonization method. These N-CDs exhibited numerous distinctive characteristics such as excellent photoluminescence, high water dispersibility, favorable biocompatibility, and superior chemical inertness. Strikingly, the as-prepared CDs as a highly efficient fluorescent probe possessed significant sensitivity and selectivity toward CAL and l-Arg/l-Lys over other analytes with a low detection limit of 58 nM and 16 nM/18 nM, respectively. The fluorescence of N-CDs could be quenched by CAL through an electron transfer process. Then, the strong electrostatic interaction between l-Arg/l-Lys and N-CDs induced the efficient fluorescence recovery. More importantly, the outstanding biosafety and excellent analyte-responsive fluorescence characteristics of N-CDs have also been verified in living cells as well as in serum and urine. Overall, the N-CDs had a wide application prospect in the diagnosis of amino acid metabolic diseases and small molecule drug sensing.The complex [Pt(AEP)Cl2]; C-1 (where, AEP = 1-(2-Aminoethyl) pyrrolidine) and its hydrolyzed diaqua form cis-[Pt(AEP)(H2O)2]2+; C-2 were synthesized for their bioactivity and in vitro kinetic study with bioactive thiol group (-SH) containing ligands (like; L- cysteine and N-ac-L- cysteine) for their biological importance for ‘drug reservoir’ activity. The Thermal Gravimetric Analysis (TGA) was executed to confirm about the weight loss due to coordinated water molecules at high temperature range. At pH 4.0, the substitution behavior of C-2 with the thiols was studied in pseudo-first order reaction condition. The interaction mechanism of thiols with complex C-2 to their corresponding thiol substituted C-3 [Pt(AEP)(L-cys)] and C-4 [Pt(AEP)(N-ac-L-cys)] (where L-cys = L-cysteine and N-ac-L-cys = N-ac-L- cysteine) were proposed from their thermodynamical activation parameters (ΔH≠ and ΔS≠), which were obtained from Eyring equation. Estrone DNA and BSA binding activity of the complexes C-1 to C-4 were investigated by gel e recognised anticancer drug cisplatin. The Reactive Oxygen Species (ROS) production was assessed by DCFDA assay in presence of the Pt(II) complexes.New antimalarial compounds with novel mechanisms of action are urgently needed to combat the recent rise in antimalarial drug resistance. Phenotypic high-throughput screens have proven to be a successful method for identifying new compounds, however, do not provide mechanistic information about the molecular target(s) responsible for antimalarial action. Current and emerging target identification methods such as in vitro resistance generation, metabolomics screening, chemoproteomic approaches and biophysical assays measuring protein stability across the whole proteome have successfully identified novel drug targets. This review provides an overview of these techniques, comparing their strengths and weaknesses and how they can be utilised for antimalarial target identification.Litter traits are critical economic variables in the pig industry as they represent a production indicator that can serve to determine sow fertility. In this study, a genome-wide association study on litter traits, including total number born (TNB), number born alive (NBA), litter birth weight (LBW), average birth weight (ABW), and piglet uniformity (PU), was carried out on two pig breeds (Yorkshire and Landrace). A total of 3 637 pigs of both breeds were genotyped using the GeneSeek GGP Porcine 50K SNP BeadChip. A mixed linear model (MLM) and fixed and random model circulating probability unification (FarmCPU) were employed in the genome-wide association studies for litter traits using combined data from the two pig breeds and data from each breed separately. Additionally, the heritability of traits was estimated using three methods-pedigree-based best linear unbiased prediction (PBLUP), genomic best linear unbiased prediction (GBLUP), and single-step best linear unbiased prediction (ssGBLUP)-and was found to lie between 0.065 and 0.1289, 0.0478 and 0.0938, 0.0793 and 0.0935, 0.1862 and 0.2163, and 0.0327 and 0.0419 for TNB, NBA, LBW, ABW, and PU, respectively. We also compared the genomic prediction accuracies and unbiasedness for litter traits of the three BLUP models. Our results indicated that the ssGBLUP method provided higher predictive accuracies and more rational unbiasedness compared with the PBLUP and GBLUP methodologies. Furthermore, based on their possible roles, eight candidate genes (INHBA, LEPR, HDHD2, CTNND2, RNF216, HMX1, PAPPA2, and NTN1) were identified as being linked with litter traits. In the middle of the test, these genes were found to be connected with pig metabolism and ovulation rate. Our results provide the insights into the genetic architecture of litter traits in pigs, and the potential single nucleotide polymorphisms (SNPs) and candidate genes identified may benefit economic profits in pig-breeding industry and contribute to improve litter traits.The design of fluorescence sensor for selective detection of Fe2+ is very important as it is part of different biochemical redox system related to a number of diseases. In many occasion sensors are unable to distinguish Fe2+ from Fe3+ ions. In the present work, we report simple chalcone type sensors for sensing Fe2+ ions in semi aqueous system. The receptors R1 and R2 have showed excellent sensing properties at pH 7 in CH3OH-H2O (11, v/v) solvent system. The fluorescence emission intensity of the complexes between hosts and Fe2+ is least affected by the other competitive metal ions leading to the formation of very tight host-guest complex. The LOD for the R1 and R2 for Fe2+ are 1.91 μM and 3.54 μM respectively, which is quite low in compared to the many other reported sensors. The practical applicability of these sensors is determined by the detection of Fe2+ in real water samples. So chalcones would be cost effective PET inhibited fluorescence sensor for Fe2+.
