The use of chemical fertilizers in agriculture, while effective for plant nutrition, poses environmental pollution risks due to their overuse and imbalance. Sustainable agricultural solutions are required to reduce reliance on chemical fertilizers. Biofertilizers, which harness the potential of beneficial soil microorganisms, are a promising alternative.

Remarkably, resorcinols with electron-withdrawing groups and halogens, which are reported in the literature as the most challenging precursors in this cyclization, are tolerated. This method leads to a variety of 2-substituted resorcin[]arenes in a single synthetic step with isolated yields up to 98%.

Therefore, we aim to investigate how MQ either in positive or negative dimensions affect different cardiovascular risk factors and diseases.
Recent Findings: We systematically searched different databases in September 2023 for longitudinal studies conducted to assess the contribution of MQ to well-established cardiovascular risk factors and diseases.
Background: Radiotherapy is one of the primary treatments for cancer, but it can cause damage to normal tissues and lead to side effects. The use of radiosensitizers can enhance the sensitivity of cancer cells to radiation, thereby reducing the amount of radiation required and minimizing damage to healthy tissues. Bismuth selenide nanoparticles (Bi2Se3 NPs) have been shown to have potential as radiosensitizers.

This approach provides a facile and versatile synthesis for functionalized 2-1,4-benzoxazines under metal-, reagent-, and solvent-free conditions. Experimental and computational studies revealed the pivotal role of 1,5-acyl migration as the self-catalytic step in the reaction selectivity.

Aim: The present study aimed to determine changes in the genital self-image and its relationship with women's sexual function in the third trimester of pregnancy and postpartum.
Methods: The participants of this prospective cohort study included 301 eligible pregnant women chosen through stratified random sampling with proportional allocation from comprehensive health centers in Gorgan, Iran.
Background: This study aimed to evaluate the psychometric indicators of the Persian version of the Sense of Belonging in Nursing School scale (SBNS).
Methods: The study conducted in Shahroud and Semnan schools of nursing and midwifery in Iran examined nursing students using a cross-sectional approach by convenience sampling method from 3/6/2023 to 24/8/2023. To assess the SBNS scale, the forward-backward procedure was used to translate it into Persian.
Recycling and revalorization of waste are currently essential for sustainable growth. Mill scale, a waste product from steel production industries, which contains high levels of iron and minimal impurities, is proposed in this study as the source to synthesize magnetite nanoparticles (FeO) for an enhancement of a lactate biosensor range. The synthesized FeO nanoparticles were coated with polydopamine (PDA) to prevent aggregation and degradation, creating a stable platform for immobilizing lactate oxidase enzyme (LOx) on their surfaces.

Achieving prolonged emulsion stability is challenging and depends on various factors, with particular emphasis on droplet size, shape, and spatial distribution. Addressing this issue necessitates an effective investigation of these parameters and finding solutions to enhance emulsion stability.

Among the ligands of human PXR is hyperforin, a constituent of St John's wort (SJW) extracts and potent inducer of human CYP3A4. It was the aim of this study to compare the effect of hyperforin and SJW formulations controlled for its content on CYP3A23-3A1 in rats.

Accordingly, it is important to use risk management and control programs in all departments of these organizations.
Objective: The present study was conducted for the first time to evaluate the risk management status of the operating room and laboratory departments of Hamadan hospitals in 2022.
Background: Pregnant women experience several changes in their appearance, body shape and body image. In some studies, there has been a relationship between these changes and the type of delivery. This study aimed to investigate the relationship of the prenatal body image and genital image with the mode of delivery preferred by pregnant women in Gorgan in 2020.

Materials And Methods: This descriptive research was conducted in order to investigate the frequency of unnecessary requests for CT scan and radiography of patients referring to the imaging department of Be'sat Hospital in Hamadan in a 4- to 6-month period. Patient information, including gender, age, type of CT scan test, the reason for requesting the test, the expertise of the requesting physician, and the result of the radiologist's report on each test, was extracted and collected.
Microfluidic paper-based analytical devices (µPADs) are leading the field of low-cost, quantitative in-situ assays. However, understanding the flow behavior in cellulose-based membranes to achieve an accurate and rapid response has remained a challenge. Previous studies focused on commercial filter papers, and one of their problems was the time required to perform the test.

By slit cutting with carefully designed geometries, desirable mechanical behaviors-such as accurate shape morphing, tunable auxetics, super-stretchability, buckling, and multistability-can be imparted to otherwise inflexible sheet materials. In addition, the kirigami sheet provides a versatile platform for embedding different electronic and responsive components, opening up avenues for building the next generations of metamaterials, sensors, and soft robotics.

Several rodent models of back pain are used in current investigations.
View Article and Find Full Text PDFWe employed density functional theory (DFT) methods to investigate the most plausible mechanism of cyclization/ring expansion of proline with -alkynylbenzaldehyde. This one-pot reaction starts with the in situ formation of azomethine ylide, which can undergo three different reaction pathways to form the final product. Two mechanisms are based on nucleophilic addition and 4π-electrocyclization of the azomethine ylide, and our results indicate that the rate-determining step (RDS) of these two cyclizations are 40.
