Optimization design and application of library face recognition access control system based on improved PCA.

The application of face recognition technology in Library Access Control System (LACS) has an important impact on improving the security and management efficiency of the library. However, the traditional face recognition methods have some limitations in the face of complex environmental conditions such as illumination and posture change. To solve this problem, an improved method combining the Aggregating Spatial Embeddings for Face Recognition (ASEF) algorithm and Principal Component Analysis (PCA) is proposed.

Single-dose suraxavir marboxil for acute uncomplicated influenza in adults and adolescents: a multicenter, randomized, double-blind, placebo-controlled phase 3 trial.

Suraxavir marboxil (GP681) is an antiviral drug inhibiting the polymerase acidic protein (PA) of RNA polymerase, of influenza. It has shown therapeutic activity against influenza A and B virus infections in preclinical studies. In this multicenter randomized, double-blind, placebo-controlled, phase 3 trial, we aimed to investigate the efficacy and safety of single-dose suraxavir marboxil (40-mg oral dose) in otherwise healthy outpatients aged 5-65 years with uncomplicated influenza unaccompanied by severe issues.

SERS-based simplified analysis of paraquat in poisoning cases: Bypassing complicated pretreatment with antioxidant sensor.

Applying antioxidant coating materials to prepare surface-enhanced Raman spectroscopy (SERS) sensing substrates can effectively enhance the sensitivity and stability for the analysis of molecules. In this study, we have leveraged SERS to develop an innovative sensor for the swift identification of Paraquat (PQ), enabling on-site detection of this herbicide. The newly devised sensor distinguishes itself through its exceptional oxidation resistance.

Exosomes derived from umbilical cord mesenchymal stem cells promote healing of complex perianal fistulas in rats.

Background: Complex perianal fistulas, challenging to treat and prone to recurrence, often require surgical intervention that may cause fecal incontinence and lower quality of life due to large surgical wounds and potential sphincter damage. Human umbilical cord-derived MSCs (hUC-MSCs) and their exosomes (hUCMSCs-Exo) may promote wound healing.

Methods: This study assessed the efficacy, mechanisms, and safety of these exosomes in treating complex perianal fistulas in SD rats.

Pyruvate Kinase M2-Responsive Release of Paclitaxel and Indoleamine 2,3-Dioxygenase Inhibitor for Immuno-Chemotherapy of Nonsmall Cell Lung Cancer.

Paclitaxel (PTX) is a first-line chemotherapeutic drug for non-small cell lung cancer (NSCLC) but it can induce indoleamine 2,3-dioxygenase (IDO) activation, which severely lowers down its immuno-chemotherapeutic effect. To address this issue, a smart peptide hydrogelator Nap-Phe-Phe-Phe-Lys-Ser-Thr-Gly-Gly-Lys-Ala-Pro-Arg-OH (Nap-T), which co-assembles with PTX and an IDO inhibitor GDC0919 to form a hydrogel GP@Gel Nap-T, is rationally designed. Upon specific phosphorylation by pyruvate kinase M2 (PKM2), an overexpressed biomarker of NSCLC, Nap-T is gradually converted to Nap-Phe-Phe-Phe-Lys-Ser-Thr(HPO)-Gly-Gly-Lys-Ala-Pro-Arg-OH (Nap-Tp), leading to dehydrogelation and sustained release of PTX and GDC0919 within NSCLC tissues.

Effects of pepper-maize intercropping on the physicochemical properties, microbial communities, and metabolites of rhizosphere and bulk soils.

Background: Intercropping increases land use efficiency and farmland ecological diversity. However, little is understood about whether and how soil biota, metabolites, and nutrients change under interspecific competition among plants. Thus, this study aimed to explore the changes in the physicochemical properties, microbial communities, and metabolites of rhizosphere and bulk soils of pepper monocropping and pepper-maize intercropping systems.

Here, we report a case of monoclonal gammopathy of renal significance, who had manifestations of IgA vasculitis, including purpura, gastrointestinal bleeding and joint pain.

Kawasaki disease involving both the nervous system and cardiovascular system: a case report and literature review.

Background: Kawasaki disease (KD), an acute self-limiting vasculitis, is the main cause of acquired heart disease. Timely diagnosis and treatment can mitigate the occurrence of complications and improve patient prognosis. Facial nerve paralysis (FNP) and ptosis are rare complications of KD and are rarely reported, but FNP is considered a high risk factor for coronary aneurysms.

Utilizing electrospinning to fabricate porous polyvinylidene fluoride/cellulose nanocrystalline/MXene films for wearable pressure sensors.

Flexible, stable, and highly sensitive pressure sensors have garnered significant interest for their potential applications in wearable electronics and human-computer interaction. However, pressure sensor substrates prepared by electrospinning currently face challenges related to inadequate mechanical properties and low conductivity. Therefore, fabricating films with high flexibility, excellent mechanical properties, and sensing capabilities is still a great challenge.

9-PAHSA ameliorates microvascular damage during cardiac ischaemia/reperfusion injury by promoting LKB1/AMPK/ULK1-mediated autophagy-dependent STING degradation.

Background: Considering that cardiac microvascular injury may play a more critical role than cardiomyocyte injury in the pathology of early ischaemia/reperfusion (I/R) injury, therapeutic strategies targeting the microvasculature are highly desirable. Palmitic acid-9-hydroxystearic acid (9-PAHSA) is a new class of bioactive anti-inflammatory lipids widely distributed in vegetables, fruits and medicinal plants, especially broccoli and apple. However, the pharmacological effects and underlying mechanisms of 9-PAHSA in protecting- against cardiac microvascular I/R injury have rarely been studied.

Our study endeavors to investigate the causal association between BC and CVD, with a focus on identifying potential metabolic mediators and elucidating their mediation effects in this causality.

Methods: In this study, we conducted two-sample Mendelian randomization (MR) to estimate the causal effect of BC (overall BC, ER+ BC, ER- BC) from the Breast Cancer Association Consortium (BCAC) on CVD including coronary heart disease (CHD), hypertensive heart disease (HHD), ischaemic heart disease (IHD), and heart failure (HF) from the FinnGen consortium.

Two-dimensional optical multiple-order differentiations based on spatial spectrum modulation.

Optical differential operations have recently attracted considerable attention owing to the capabilities of ultrafast speed and low power consumption. The transfer function, which embodies the frequency-domain characteristics of differential systems, plays an important role in differentiator design. Here, we report a super-Gaussian aperture differential filter, and we reveal unique characteristics of odd- and even-order transfer functions and corresponding differential effects via spatial spectrum modulation.

Regression prediction of tobacco chemical components during curing based on color quantification and machine learning.

Color is one of the most important indicators to characteristic the quality of tobacco, which is strongly related to the variations of chemical components. In order to clarify the relationship between the changes of tobacco color and chemical components, here we established several prediction models of chemical components with the color values of tobacco based on machine learning algorithms. The results of correlation analysis showed that tobacco moisture content was highly significantly correlated with the parameters such as a, H and H°, the reducing sugar and total sugar content of tobacco was significantly correlated with the color values, and the starch content was highly significantly correlated with the color values except for b and C.
