Exploring the determinants of unhealthy dietary behaviors among pregnant women in China using the Theory of Planned Behavior-a cross-sectional study.

Background: Pregnant women in China are at risk of malnutrition due to an interplay of physiological, psychosocial, and environmental factors. Understanding the factors influencing dietary behaviors in pregnant women is vital for promoting maternal and infant health. This study explores the determinants of dietary behaviors among pregnant women in China based on the Theory of Planned Behavior (TPB).

syn-tasiRnas targeting the coat protein of potato virus Y confer antiviral resistance in .

Trans-acting small interfering RNAs (tasiRNAs) are 21-nt phased (phased siRNAs) resulting from successive DCL-catalyzed processing from the end of a double-stranded RNA substrate originating from the RDR of an AGO-catalyzed cleaved RNA at a micro RNA target site. Plant tasiRNAs have been synthesized to produce synthetic tasiRNAs (syn-tasiRNAs) targeting viral RNAs that confer viral resistance. In this study, we engineered syn-tasiRNAs to target potato virus Y (PVY) infection by replacing five native siRNAs of TAS1c with 210-bp fragments from the coat protein (CP) region of the PVY genome.

Methyltransferase-like (METTL) homologues participate in antiviral responses.

Methyltransferase (MTase) enzymes catalyze the addition of a methyl group to a variety of biological substrates. MTase-like (METTL) proteins are Class I MTases whose enzymatic activities contribute to the epigenetic and epitranscriptomic regulation of multiple cellular processes. N-adenosine methylation (mA) is a common chemical modification of eukaryotic and viral RNA whose abundance is jointly regulated by MTases and METTLs, demethylases, and mA binding proteins.

Strategies for Engineering Virus Resistance in Potato.

Potato () is an important vegetable crop that plays a pivotal role in the world, especially given its potential to feed the world population and to act as the major staple food in many developing countries. Every year, significant crop loss is caused by viral diseases due to a lack of effective agrochemical treatments, since only transmission by insect vectors can be combated with the use of insecticides, and this has been an important factor hindering potato production. With the rapid development of molecular biology and plant genetic engineering technology, transgenic approaches and non-transgenic techniques (RNA interference and CRISPR-cas9) have been effectively employed to improve potato protection against devastating viruses.

Same-Day Cancellation is Higher in Outpatient Pars Plana Vitrectomy for Proliferative Diabetic Retinopathy.

Purpose: Safety and efficiency of ambulatory pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR) patients is worthy of attention, since patients always have severe systemic diseases. The purpose of this study was to compare the incidence of same-day cancellation of PPV for PDR between outpatients and inpatients and to analyze the causes of cancellations.

Patients And Methods: This is a retrospective review of consecutive PPV procedures for PDR from January 2019 to April 2021 at either the ambulatory or the inpatient surgery center in an academic tertiary referral center.

Comparison of 3 Rates for the Continuous Infusion of Mivacurium During Ambulatory Vitreoretinal Surgery Under General Anesthesia: A Prospective, Randomized, Controlled Clinical Trial.

Purpose: Mivacurium, the shortest-acting benzylisoquinoline nondepolarizing neuromuscular blocker used in clinical practice, is suitable for short-term ambulatory operations under general anesthesia. We investigated the neuromuscular blockade effect of different maintenance doses of mivacurium during ambulatory vitreoretinal surgery under general anesthesia and tried to determine the appropriate maintenance dose.

Patients And Methods: Ninety-nine patients undergoing general anesthesia for elective ambulatory vitreoretinal surgery were randomly divided into three groups using the random number table method.

AlkB RNA demethylase homologues and N -methyladenosine are involved in Potyvirus infection.

Proteins of the alkylation B (AlkB) superfamily show RNA demethylase activity removing methyl adducts from N -methyladenosine (m A). m A is a reversible epigenetic mark of RNA that regulates human virus replication but has unclear roles in plant virus infection. We focused on Potyvirus-the largest genus of plant RNA viruses-and report here the identification of AlkB domains within P1 of endive necrotic mosaic virus (ENMV) and an additional virus of a putative novel species within Potyvirus.

The Reversible Methylation of m6A Is Involved in Plant Virus Infection.

In recent years, m6A RNA methylation has attracted broad interest and is becoming a hot research topic. It has been demonstrated that there is a strong association between m6A and viral infection in the human system. The life cycles of plant RNA viruses are often coordinated with the mechanisms of their RNA modification.

A Spiro-MeOTAD/GaO/Si p-i-n Junction Featuring Enhanced Self-Powered Solar-Blind Sensing via Balancing Absorption of Photons and Separation of Photogenerated Carriers.

Solar blind ultraviolet (SBUV) self-powered photodetectors (PDs) have a great number of applications in civil and military exploration. GaO is a prospective candidate for SBUV detection owing to its reasonable bandgap corresponding to the SBUV waveband. Nevertheless, the previously reported GaO photovoltaic devices had low photoresponse performance and were still far from the demands of practical application.

Inhibitory Effect of Osthole from (L.) on a Common Fungal Pathogen of Potato.

Preparation of Substrate for Flavorant from Chicken Bone Residue with Hot-Pressure Process.

Hot-pressure extraction (HPE), which is regarded as a "green" technology, was applied to extract nutrients (protein, collagen, and minerals) from chicken bone residue (CBR). Amino acids (AA), color, and volatile flavor compounds of chicken bone extract (CBE) were also investigated. Results showed that contents of protein, total soluble solids, minerals, and collagen of CBE were positively correlated with extraction time and temperature.

The influence of p38 mitogen-activated protein kinase inhibitor on synthesis of inflammatory cytokine tumor necrosis factor alpha in spinal cord of rats with chronic constriction injury.

Background: Tumor necrosis factor alpha (TNF-alpha) could trigger p38 mitogen-activated protein kinase (MAPK) activation. Conversely phosphorylated p38 (p-p38) could induce the upregulation of TNF-alpha. In this study, we examined the hypothesis that chronic constrictive injury (CCI) of the sciatic nerve could promote spinal cord release of TNF-alpha and produce allodynia via the p38 MAPK pathway.
