We concluded that stronger brain-behavior correlation in AMD may suggest a role for region-specific connectivity in supporting memory in the context of AMD.Estrogen receptor alfa (ERα) is expressed in approximate 70% of breast cancer (BC) which is the most common malignancy in women worldwide. To date, the foremost intervention in the treatment of ER positive (ER+) BC is still the endocrine therapy. However, resistance to endocrine therapies remains a major hurdle in the long-term management of ER + BC. Although the mechanisms underlying endocrine resistance are complex, cumulative evidence revealed that ERα still plays a critical role in driving BC tumor cells to grow in resistance state. selleckchem Fulvestrant, a selective estrogen receptor degrader (SERD), has moved to first line therapy for metastatic ER + BC, suggesting that removing ERα would be a useful strategy to overcome endocrine resistance. Proteolysis-Targeting Chimera (PROTAC) technology, an emerging paradigm for protein degradation, has the potential to eliminate both wild type and mutant ERα in breast cancer cells. Excitingly, ARV-471, an ERα-targeted PROTAC developed by Arvinas, has been in phase 1 clinical trials. In this review, we will summarize recent progress of ER-targeting PROTACs from publications and patents along with their therapeutic opportunities for the treatment of endocrine-resistant BC.Dysfunction of bone marrow mesenchymal stem cells (BMSCs) is involved in the pathogenesis of steroid-induced osteonecrosis of the femoral head (SONFH). Long noncoding RNAs (lncRNAs) contribute to biological effects exerted on BMSCs by regulating the expression of genes. However, most recent studies have focused on the role of lncRNAs in modulating the imbalance between osteogenic and adipogenic differentiation but not apoptosis, proliferation, cell cycle and migration of BMSCs, especially in Dex-treated BMSCs. In this study, we conducted a microarray analysis to investigate the differential expression profiles of lncRNAs between human BMSCs (hBMSCs) obtained from patients with SONFH and control patients with femoral neck fracture. The microarray analysis showed that a total of 48 differentially expressed lncRNAs were identified in hBMSCs between the two groups, including 24 upregulated lncRNAs and 24 downregulated lncRNAs. Among of them, LINC00473 was found to be significantly downregulated. In the following study, we found that 10-6 mol/L Dex significantly inhibited proliferation, arrested cell cycle at the G1 phase, increased caspase-3 activity, induced apoptosis and impeded the migration of hBMSCs, while downregulation of the expression of LINC00473 produced results that were in line with the results of the microarray analysis in a time-dependent manner. Interestingly, upregulation of LINC00473 attenuated the negative effects caused by 10-6 mol/L Dex on hBMSCs, except for cell cycle arrest. Furthermore, it should be noted that LINC00473 had no effect on the proliferation and cell cycle of hBMSCs in the absence of Dex. Collectively, our data revealed that LINC00473 attenuated apoptosis, promoted the proliferation and migration of Dex-induced hBMSCs, which are not involved in interference with the cell cycle of hBMSCs.The correlation between potato components and Maillard reaction derivative harmful products (MRDHPs) formation during heat-processing was assessed in nine commercial potato varieties in China. Principal component analysis (PCA) combined with canonical correlation analysis (CCA) approach was performed to explore their relationships. The variables contributing most to the PCA results were extracted for CCA, and the results indicated that several amino acids, including lysine, tryptophan, alanine, phenylalanine, aspartate, and glutamate, have significant impacts on acrylamide and β-carboline heterocyclic amine formation. Moreover, 5-O-caffeoylquinic acid, 3-O-caffeoylquinic acid, α-solanine, and α-chaconine were also important factors associated with acrylamide and β-carboline heterocyclic amine formation. Optimally using raw potato varieties based on the impacts of these factors can help control MRDHP formation during thermal processing. For the first time, such approach was applied, which may be a useful tool for discovering the correlation of food components and MRDHPs.Olive anthracnose is caused by fungal species within the Colletotrichum acutatum, C. gloeosporioides and C. boninense complexes. Anthracnose causes severe pre- and post-harvest olive drupe fall. This study aimed to design a species-specific qPCR assay, based on klap1 gene, suitable for C. acutatum s.s. quantification in cv. link2 Galega Vulgar fruit samples. The developed qPCR assay presented a detection limit of 10.14 fg/reaction, and a linear cycle threshold of R2 = 0.996. C. acutatum inoculum was detected in pulverized olive fruits, and in early infection stages, before symptom appearance, 16 h after inoculation (Ct values = 28.29 ± 1.1). In olive samples, the derived melting curve was specific presenting a single dissociation peak (Tmelting = 88.7 °C). The designed assay was effectively applied in C. acutatum detection and quantification using infected olive samples, with a LOD of 0.59 ng and a LOQ of 1.8 ng, allowing its application to orchard management.Gold nanoparticles (AuNPs)-based lateral flow assay (LFA) enables a rapid detection of tetracycline (TET) in food samples but suffers from low sensitivity. Herein, metal-polydopamine framework (MPF), as a label, was employed to load monoclonal antibodies (mAbs) directly as the probe in LFA for highly sensitive sensing of TET. Combining zeolitic imidazolate framework (ZIF-67) and polydopamine (PDA), a stable MPF with large size, well water-dispersible, excellent affinity and optical properties was prepared through a versatile layer-by-layer assembly (LLA) strategy. Under optimized conditions, the biosensor (MPF-LFA) exhibited a great linear relationship in the range of 0.09-6 ng/mL and a detection limit of 0.045 ng/mL for TET detection, which was over 66-fold more sensitive than traditional AuNPs based LFA. Furthermore, the MPF-LFA was successfully applied to the screening of TET in fish, chicken, milk and shrimp samples with satisfied recoveries from 91% to 114%.The objective of this study was to investigate the effects of four commercial lactic acid bacteria (LAB), namely L. acidophilus, L. casei, L. helveticus and L. link3 plantarum, on the phenolic profiles, antioxidant capacities and flavor profiles of jujube juices prepared from two crop varieties (Ziziphus Jujuba cv. Muzao and Hetian). Results showed that both jujube juices were excellent matrices for LAB growth with more than 11 log CFU/mL of viable counts at the end of fermentation. LAB fermentation dramatically increased total phenolic content, while decreased total flavonoid content of jujube juices. However, antioxidant capacities based on DPPH and FRAP methods were significantly improved by LAB fermentation and positively correlated with caffeic acid and rutin contents. Furthermore, a total of 74 volatile compounds were identified and increased in total content by LAB fermentation, which resulted in 22 and 19 new flavor volatiles formation in Muzao juice and Hetian juice, respectively.Fat-filled milk powders (FMP) are inexpensive milk alternatives predominantly exported to developing countries to satisfy growing demands for dairy proteins. Harsh climatic and sanitary conditions, poor border controls and relatively long periods for distribution and storage enhance the inherent vulnerability of FMP to fraud and stability. Rapid, low-cost methods are needed for extensive routine authentication of FMP products. This study investigated, for the first time, the sample integrity and the quality dynamics of 7 Nigerian FMP brands stored for 7 weeks at 40 °C. The prominent melamine and urea absorption peaks were absent, but protein contents were below the permitted limit. The peak absorbance of the OH functional group increased while the tryptophan contents decreased with storage time. Multiclass analyses differentiated the fresh FMP brands from one another, and from those that were aged. Robust interval-PLS predictions obtained for storage time may be excellent indicators of FMP freshness and stability.Quinoa protein possesses great amino acid profiles and can be a potential food ingredient with broad applications. The objective of this study was to investigate the effect of different drying methods, namely freeze drying, spray drying, and vacuum drying on the functional and physicochemical properties of quinoa protein isolate, e.g., morphology, amino acid composition, SDS-PAGE profile, sulfhydryl/disulfide content, secondary structure, surface hydrophobicity, and thermal stability. The freeze-dried protein exhibited the highest emulsification capacity and stability and oil binding capacity, which was contributed to its higher surface hydrophobicity, while the spray-dried sample had the highest solubility and water absorption capacity at pH 7. Gels (8%) prepared with the freeze-dried protein had higher elastic and viscous modulus than that from others. The freeze-dried protein had the highest maximal denaturation temperature but lowest enthalpy, which may be attributed to its higher amount of random coil but lower percent of regular α-helix and β-sheet structures. Overall, quinoa protein isolate from different processing methods demonstrated distinct functional properties. This information will be useful to optimize quinoa protein production and benefit its applications.This paper reports an experimental study of the formation and properties of dark chocolate prepared using novel CB alternative fats (CBAs) symmetric (OSatO) and asymmetric (SatSatO) mixed-acid triacylglycerols (TAGs), in which Sat and O represent saturated fatty acids (stearicS + palmiticP) and oleic acid moieties, respectively. It was found that the ternary fat mixtures of CB/SatSatO/OSatO with a ratio of CB/(SatSatO + OSatO) of 11 formed the most stable β-form of the double chain length (DCL) structure (β-2), which revealed sufficient hardness and sharp melting profiles around body temperature without tempering processes. Fat bloom formation was not observed in dark chocolate with CBAs at ratios of CB/SatSatO/OSatO of 50/20/30-50/0/50 during the one-year storage test at temperatures between 15 °C and 30 °C. Overall, the present study has shown that fat mixtures made of CB/SatSatO/OSatO, which are rich in oleic acid moieties, can be employed as a cocoa butter equivalent (CBE) fat without tempering procedures.
Physical and emotional parent-infant closeness activate important neurobiological mechanisms involved in parenting. In a neonatal care context, most research focuses on physical (parental presence, skin-to-skin contact) aspects; insights into emotional closeness can be masked by findings that overemphasise the barriers or challenges to parenting an infant during neonatal care.

To explore existing qualitative research to identify what facilitates and enables parents' experiences of emotional closeness to their infants while cared for in a neonatal unit.

A systematic review using meta-ethnographic methods. Search strategy involved searches on six databases, author runs, and backward and forward chaining. Reciprocal translation was used to identify and compare key concepts of parent-infant emotional closeness.

Searches identified 6992 hits, and 34 studies from 17 countries that involved 670 parents were included. Three overarching themes and associated sub-themes were developed. 'Embodied connections' describes how emotional closeness was facilitated by reciprocal parent-infant interactions, spending time as a family, and methods for parents to feel connected while physically separated.
